Abstract

Objectives To analyse the views of general practitioners (GPs) about how they can provide care to homeless people (HP) and to explore which measures could influence their views.

Design Mixed-methods design (qualitative –> quantitative (cross-sectional observational) → qualitative). Qualitative data were collected through semistructured interviews and through questionnaires with closed questions. Quantitative data were analysed with descriptive statistical analyses on SPPS; a content analysis was applied on qualitative data.

Setting Primary care; views of urban GPs working in a deprived area in Marseille were explored by questionnaires and/or semistructured interview.

Participants 19 GPs involved in HP's healthcare were recruited for phase 1 (qualitative); for phase 2 (quantitative), 150 GPs who provide routine healthcare (‘standard’ GPs) were randomised, 144 met the inclusion criteria and 105 responded to the questionnaire; for phase 3 (qualitative), data were explored on 14 ‘standard’ GPs.

Results In the quantitative phase, 79% of the 105 GPs already treated HP. Most of the difficulties they encountered while treating HP concerned social matters (mean level of perceived difficulties=3.95/5, IC 95 (3.74 to 4.17)), lack of medical information (mn=3.78/5, IC 95 (3.55 to 4.01)) patient's compliance (mn=3.67/5, IC 95 (3.45 to 3.89)), loneliness in practice (mn=3.45/5, IC 95 (3.18 to 3.72)) and time required for the doctor (mn=3.25, IC 95 (3 to 3.5)). From qualitative analysis we understood that maintaining a stable follow-up was a major condition for GPs to contribute effectively to the care of HP. Acting on health system organisation, developing a medical and psychosocial approach with closer relation with social workers and enhancing the collaboration between tailored and non-tailored programmes were also other key answers.

Conclusions If we adapt the conditions of GPs practice, they could contribute to the improvement of HP's health. These results will enable the construction of a new model of primary care organisation aiming to improve access to healthcare for HP.

Strengths and limitations of this study

  • Using mixed methods permitted us to have a deeper analysis of a complex phenomenon.

  • We obtained a high quantitative participation rate (73%), compared with similar other studies conducted on general practitioners (GPs).

  • Qualitative analyses were performed by only one data coder. However, to enhance the accuracy of our interpretation process, we discussed our analysis process and conclusions with different actors (directors of this study, interviewed GPs, external actors) on critical times of the interpretation of data.

  • During the quantitative phase, to satisfy our operational objectives, we selected only GPs working in the poorest areas of Marseille: extrapolation of our results should be limited to GPs working in urban area, in low-income suburbs and in countries with similar social policies as in France.

Introduction

The number of homeless people (HP) increased by 50% between 2001 and 2012 in France,1 with a similar rate in Europe during the same time frame.2 In 2012, in France, almost 900 000 people lacked personal housing, and almost 3 000 000 lived under poor-quality housing conditions.3 This situation continues to affect a growing number of households and young people.4 European Federation of organisations working with the people who are homeless (FEANTSA) has recently developed a European Typology of Homelessness and housing exclusion (ETHOS), to improve the understanding and measurement of homelessness in Europe, and provide a common language for transnational exchanges on homelessness.5 This typology considers four operational categories of homelessness:

  • Roofless: people living rough, or in emergency accommodations;

  • Houseless: people living in homeless shelters or receiving longer term support (due to homeless);

  • Insecure: people living in insecure accommodations or under threat of eviction;

  • Inadequate: people living in temporary/non-conventional structures, in unfit housing or under conditions of extreme overcrowding.6

Given the increase of homelessness in the past years, improving the health and social conditions of the homeless has become a priority for European social politics;2 ,7 it is more important than ever to explore the effectiveness and feasibility of a scheme in which ambulatory general practitioners (GPs; family doctors) play a central role in the primary care for the homeless. Indeed, HP have complex healthcare needs, accompanied by somatic, psychiatric and social troubles.8 ,9 These people suffer from higher morbidity9–11 and earlier mortality compared with people with stable housing. The average age of death is between 40 and 50 years12 ,13 and the standardised mortality ratios in high-income countries is typically reported from 2 to 5 times the age-standardised general population.9

They face difficulties in accessing primary care14–16 and go through inadequate therapeutic itineraries, with multiple visits to emergency services.17 ,18 We know that GPs see a significant proportion of the homeless population: 84% of HP declared that had been consulted by a GP within a year of a study performed in France in 2001;19 a Canadian study shows that 43% of HP had a designated family doctor.20 Family doctors are generally viewed positively by precarious patients which includes HP: they build a confident relationship and are seen as a support for these patients.21 However, GPs are not identified by HP as the first person to turn to for medical assistance whenever they feel ill.22 ,23

The debate between developing specialised structures for HP or adapting ‘non-specialised’ general practice for HP has not yet been resolved.24 According to a recent literature review, primary healthcare programmes specifically tailored to homeless individuals might be more effective than standard primary healthcare.25 Such programmes could also yield more appropriate care and give the homeless patient a better experience in their care.26 But tailored programmes have many limitations: these programmes (particularly associative or humanitarian programmes) often have insufficient resources to meet such high-level care needs;27 furthermore, such programmes could reinforce the feeling of exclusion of the homeless, and enhance ghettoisation of their care.28

It has been described that GPs felt multiple difficulties in caring for and ensuring continuity of care for precarious or homeless patients. Most of the studies examining views of GPs in France targeted precarious patients or migrants; they mostly used a descriptive approach or targeted ‘specialised’ or ‘involved’ GPs.29–33

We made the hypotheses that, involving ‘non-specialised’ GPs could improve the health of the homeless, by permitting better access and continuity of global care and patient-centred care, if we can adapt their practice conditions for managing HP's care.

Our first objective was to analyse the views of GPs about how they can provide care to HP and to explore which measures could influence these views. Second, we aimed to:

  • Quantify the exposure of GPs working in a poor area restricted to homelessness,

  • Describe the knowledge of GPs working in a poor area about homelessness,

  • Identify and quantify the difficulties and barriers that GPs face in taking care of HP.

Methods

We performed an explanatory sequential study (qualitative, then quantitative, then qualitative phases), in Marseille (France), between November 2013 and March 2015.

Research by mixed methods was recently developed in the healthcare field, especially in public health and primary care.34–37 These methods involve integrating quantitative and qualitative data collection and analysis in a single study of one phenomenon, in order to obtain wealth, breadth and depth in the analyses of the data collected.38 ,39 These approaches rely on a pragmatic worldview and are of particular interest in complex or multidisciplinary areas, like systems organisations, precariousness40 or homelessness.41 ,42

In the present study, qualitative and quantitative data complement each other:

  • Phase 1 was qualitative and aimed to get a better understanding about the way GPs care for the homeless. For this phase we recruited GPs who were involved with the homeless. Our results highlighted relevant propositions to construct a closed questionnaire for phase 2.

  • Phase 2 aimed to quantify exposure, knowledge, difficulties and involvement of GPs with a standard practice in the care of the homeless. We noticed divergent opinions about how much these GPs could contribute to the health of the homeless. It thus appeared relevant to understand why these GPs had divergent opinions, and why they seemed to be different from the involved GP's opinion.

  • That is why phase 3 aimed to characterise the views of GPs about their role in care giving to the homeless, and to explore deeper which factors could influence these views.

Last, but not least, we propose a deeper reflection by simultaneously discussing the results of both phases.

Phase 1: building hypotheses with GPs involved in care giving for HP (qualitative)

Preliminary assumptions

We aimed to explore and understand practices and knowledge of GPs who already have experience in managing care for HP. At this point, we thought that GPs could be a lever to improve the health of HP. Our questions to explore the views of doctors were built on the basis of a few elements from the literature and first exchanges with several GPs particularly involved in the care of the homeless. The researcher (who performed the interviews and analysis) had no experience in taking care of HP in France, before this phase.

Population and sampling

This phase targeted the GPs who were considered as ‘involved’ with the homeless: GPs who were working in specialised centres for HP or precarious patients, or ambulatory GPs who considered themselves involved in and/or exposed to homelessness. First the GPs were identified working in specialised care centres for precarious or HP. Three of them had already been identified by HB to be particularly involved with the homeless, who had established contact with them before the construction of this protocol. We, then, extended the sample using a ‘snowball’ method. This method is justified when we want access to a specific population that is hard to find and to maximise the chance of acceptance.43 We ensured the diversity of our sample by collecting data on age, sex, characteristics of GPs practice and patients. We stopped the inclusion when saturation of data had been reached.43 We did not perform repeat interviews. GPs were recruited from November 2013 to February 2014.

Data collection

Semistructured interviews explored views of ‘involved’ GPs about:

  • Health, access to healthcare and continuity of care for homeless people;

  • Care giving by GPs for homeless people;

  • Recovering medical histories and using shared electronic medical records for the HP (we did not develop this last part on this research; see online supplementary file 1).

The same investigator (principal author of this article, master thesis student and resident in general practice at this time and who was presented as such) contacted the GPs first by phone, agreed to an appointment with them and then conducted the interviews in places chosen by each GP. The interviews were conducted after two pilot tests. They were conducted face-to-face, recorded (only audio) and then fully transcribed. Field notes were made during and after the interviews, about attitudes of GPs, but not recorded information and the place of the interviews. All the interviews were anonymised as soon as they were concluded. An information letter was given to each GP and a written consent was obtained for publishing the results.

Analyses

We performed a content analysis on the transcriptions, using N-Vivo V.10. This software is useful for qualitative analyses, enabling enhanced validity and rigour in the qualitative analysis process.44 Owing to time and financial constraints, only one data coder performed the analyses (MJ), but all the steps of the coding were followed and approved by HB. We did not return the transcripts to the interviewed GPs, but we asked their opinion about our interpretation of data (during a meeting where we shared the interpretation of the first five interviews, asking for their feedback when results had been written).

Phase 2: describing views of a representative sample of ‘standard’ GPs (quantitative)

We performed a descriptive, cross-sectional study.

Population and sampling

Phase 2 targeted GPs having a standard practice of family medicine in France. They could be exposed or involved in the health of HP, or not. In order to make the script clearer, we named these GPs ‘standard GPs’. We included GPs who were working in the centre or in the northern part of Marseille (the areas which are most affected by homelessness), in private offices or health centres, working alone or in groups. Two public databases of GPs allowed us to identify all GPs who could meet the inclusion criteria. GPs with divergent information in these databases were contacted before randomisation to confirm their eligibility. We then randomised 150 GPs. They were recruited from June 2014 to July 2014.

Data collection

We relied on our results from phase 1 (especially here: thematic about the perceived difficulties), and data from the literature, to prepare the questionnaire for phase 2. We tested the questionnaire on two GPs before the real application. The questionnaire explored GPs' general characteristics, exposures, knowledge and levels of difficulties in care giving and views about how much they can contribute to the primary care of HP (see online supplementary file 1). In order to increase the response rate, we proposed four modes of answer: phone, post mail, internet (with a secured link on SurveyMonkey) or face-to-face. An information letter was given to each GP.

Analyses

We performed descriptive analyses with SPSS V.20, with means and confident intervals. Views of GPs were explored using the Likert scale. The main variable was the opinion of GPs about how much they could contribute to the care of HP.

Phase 3: exploring views of ‘standard’ GPs and understanding which conditions could influence their views (qualitative)

Preliminary assumptions

At this point we had more specific assumptions, given the results of phases 1 and 2. We aimed to get a deeper understanding of the phenomenon. We wanted to explore how the involvement and the effectiveness of GPs about taking care of HP should depend on organisational or individual factors (linked to patients and/or health professional). We expected to find solutions which could be relevant for GPs when they treat HP. The researcher had work experience in two centres for the socially deprived patients before this phase.

Population and sampling

Phase 3 targeted ‘standard’ GPs as defined before. GPs were recruited from the list of those who responded to the questionnaire in phase 2, between December 2014 and March 2015. We used a quota sampling method to have a diversity based on age, sex, type of exercise (private/employed /mixed), having a secretariat or not, working alone or with other GPs at office and exposure to HP in their practice. We stopped inclusion when saturation of data had been reached. We did not perform repeat interviews.

Data collection

We performed semistructured interviews, exploring the views of GPs about: healthcare giving to HP, barriers and difficulties in achieving their contribution (see online supplementary file 1). The same investigator (principal author of this article, doctoral student and resident in general practice at this time, and who was presented as such) contacted the GPs first by phone, agreed to an appointment with them, then conducted the interviews in places chosen by each GP. The interviews were conducted after two pilot tests. They were conducted face-to-face, recorded (only audio) and then fully transcribed. Field notes were made during and after the interviews, about the attitudes of GPs, not recorded information, and the place of the interviews. All the interviews were anonymised as soon as they were concluded. An information letter was given to each GP and a written consent was obtained for publishing the results.

Analyses

We performed an inductive thematic content analysis, using N-Vivo V.10. Owing to time and financial constraints, only one data coder performed the analyses (MJ), but all the steps of the coding were followed and approved by HB. We did not return the transcripts to the interviewed GPs (due to a confidential policy), but we returned the results when they were written, before publication.

Ethics

All the parts of this study were registered on CNIL (French National Commission for Data Protection and Liberties).

Results

Phase 1: results from interviews on ‘involved GPs’

Characteristics of the sample and interview

We interviewed 19 GPs, mostly at their office (among the others, 1 was performed at the GP's residence, 1 in a public area and 2 in the public health department). We obtained data saturation on the 18th interview, confirmed by the 19th. The average duration of the interviews was 1 hour. Five GPs refused to participate (lack of concern of homelessness by two GPs and lack of time for interview by three of them). For five other GPs, we could not obtain first contact. The sample was diversified by age, sex, type of exercise and structure of the exercise. Most of them13 were either employed or had mixed practice. None of them declared receiving any patient with a high or very high social level (table 1).

Table 1

Characteristics of ‘involved GPs’ (phase 1, n=19 GPs)

Coding tree

We developed three main categories on this phase (see online supplementary file 2):

  • Access and continuity of healthcare for the HP;

  • Sharing of medical information when having medical record of the HP;

  • Care for HP by GPs.

This article discussed the main themes on this last category. The themes were derived from the data.

Three categories of difficulties identified in the care of the homeless

We identified three categories of difficulties for GPs in providing care to the homeless (table 2):

  1. Personal difficulties, which included practical questions (money/time/reception/management of consulting) and emotional or psychological consequences for the doctors while they care for HP;

  2. Difficulties with care management: the care management was perceived as complex and heavy. GPs explained these difficulties mostly by: multiple issues for patients, difficulties in knowing medical data and overinvestment of doctors;

  3. Difficulties in interacting with the homeless patients (physical appearance of HP, communication and relation with the patient, comprehension of the patient).

Table 2

Difficulties intented by ‘involved’ GPs about taking care of a homeless in general practice

Personal obstacles and difficulties in healthcare management were identified by some other GPs (respectively, 18 and 16 GPs), than the difficulties in interacting with the homeless patients (14 GPs). When personal dilemmas were identified, they took an important part in the discourse of GPs (108 verbatims), showing that it had important consequences on their view about how they treated the HP. Issues about managing social problems of the patients (social rights, life context and social condition, social rehabilitation) weren't identified as a category of difficulties during the analysis of the involved GPs' speech. This was expressed by the GPs as a limitation for the HP to have access to healthcare, or staying in a stable follow-up relationship.

All GPs spoke of their limitations and about how to correctly manage HP. They described these limitations mostly as experts rather than express their difficulties. Here, the first argument concerned limitations about coordination and follow-up (limitations due to the life context of homeless patients, unstable follow-up relationship, inappropriate answers of ‘standard’ GPs, difficulties to identify supports as specialised centres, limitations of relation between outpatient care and institutional care, lack of information about the medical history of the homeless patients, limitations due to their private practice or common law system). Eight GPs expressed that a proper follow-up was most of the time impossible for chronic diseases.

Strengths of GPs and conditions to improve access and continuity of care for the homeless

GPs as one of the solutions to improve access and continuity of care for the homeless

We asked the involved GPs about which of the solutions could improve the access and the continuity of care for HP. Family doctors or common law system were perceived as one of the solutions by 13 GPs (on the 19 interviewed). Fifteen GPs stated that outpatient treatment could have a positive impact on HP.

They advanced three main arguments:

  1. GPs can prevent and/or get out of precariousness:

It seemed that the contribution of GPs, as family doctors, could be really important when the patients are ‘on the top of the slide’ (as one GP expressed in the focus group performed after the first analyses). GPs are in a good position to know life context and environment of their patients, so that they are the best ones to screen vulnerability. The involved GPs mostly empowered themselves in preventing precariousness of their patients. Some expressed that GPs could help HP to get back to a social stability, to come back in the ‘system’: “I’m sure…with health, taking into account health, it can be a way to get into rehabilitation and the return to socialization” said one GP (working in ‘Permanence d'Accés aux Soins de Santé (PASS) psychiatrique’, a specialised structure for the access to care for precarious people with psychiatric troubles), “we (the GPs) are the entrance of the system…we guide into the system” said another GP (a GP who had worked as a family doctor and was involved in medical consultations for HP into an emergency accommodation).

  1. GPs as a solution for reducing stigmatisation of HP:

Much more than a simple return to common law system, GPs explained that being received in a common medical office, or experiencing hospitality and respect in healthcare encounters, can improve the self-esteem of HP. It can become an integral part of care for HP. For example, a GP who works in a private medical office where he received some HP and also in a structure for treating patients of addictions, explained: “I think that it can be gratifying to be in a waiting room…with a mother and her baby, a little old lady and many other average persons”.

  1. GPs are a strength for beginning and manage a stable follow-up:

GPs felt they could create trust with homeless patients. This trust, combined to positive attitudes, was perceived as a solution to create a positive therapeutic relationship. Furthermore, GPs were described as referent, who can build a solid network around the patient, which can help to provide global care. GPs explained that these elements could permit a better use of care and a more stable follow-up relation for HP. However, they recalled the limits of the management of HP's healthcare for succeeding in the private activity.

A significant proportion of GPs (7 out of 19) spontaneously expressed that working with HP had a favourable impact on them too. It could be for some of them a necessary activity, for others a type of care that suited them better, a challenge they took pleasure to meet, a better relationship or a sense of accomplishment.

Some adaptations are necessary when taking care of HP

Two major adaptations appeared necessary to succeed in improving access and continuity of primary care for HP:

 First, a necessary adaptation for GPs to take care of HP:

All the ‘involved’ GPs (19 GPs) explained in many fields how they must adapt their practice, behaviour or care setup if they want to be efficient in receiving and treating HP. We identified four categories of adaptation. Three of them reflected the difficulties identified by GPs:

  1. Practical setup (19 GPs, 29 verbatim): by proposing an immediate response with no appointment for consultations, using a secretary at office, or practising the ‘third-party payment’ (which means that GPs are directly paid by insurance so that patients need not pay for the consultation);

  2. Interaction with homeless patients (19 GPs, 175 verbatim): by adapting GP's behaviour when treating HP (showing respect and empathy, building a trusting relationship…), understanding differences in behaviour of homeless patients or taming the patient;

  3. Management of care (19 GPs, 175 verbatim): by adapting the objectives of care, or adapting the practice to homeless patient life, with an active outreach strategy (‘going to’ the patient).

The fourth category concerned learning about specificities of precariousness or homelessness (6 GPs, 12 verbatim).

- Second, the importance of a global, medicopsychosocial, management:

In the discussions with 15 GPs, social issues were more important than medical questions when they treated homeless patients, so that the social management became caring for the homeless. Furthermore, 14 GPs explained how the social workers played an important role, to ensure access to healthcare, but also to treat other social problems of the homeless (food, housing). Furthermore, the importance of a multidisciplinary care management was expressed by 13 GPs. They explained here interest of working with a team of different professionals, including street teams, social workers and psychologists. Eight GPs expressed the need to build a network throughout the city to connect professionals who practice with homeless.

Phase 2: results from ‘standard’ GPs who worked in area concerned by homelessness

Characteristics of the sample

Among the 150 doctors randomised, 6 were excluded because they did not meet the inclusion criteria and 38 did not respond to the questionnaire. One hundred and five questionnaires were usable; hence, the response rate was 73% (figure 2). Most of the included GPs were older than 50 years (72%), and were men (74%). Only 9% of them had an employed or mixed practice. Our sample was of a similar age and structure of practice profile to the 2014 average mix of GPs working in medical private office or health centres in France.45 However, there were fewer women (26%) in our sample in comparison to the average (35.4%) (p=0.04; table 3).

Table 3

Flow chart (‘standard GPs’, phase 2). GP, general practitioner.

Exposure and knowledge of ‘standard’ GPs about precarious patients

A large majority of the GPs (79%) declared having already received a homeless at office (table 4). These GPs received very few HP (almost never or few often for 79.2% of them). If they were mostly exposed to moderate homelessness (insecure or inadequate housing for 62.8% of the GPs), a significant proportion of them (37.1%) were more likely to also receive roofless or houseless patients.

Table 4

Exposition and knowledge of ‘standard’ GPs about homelessness

Few GPs (6.1%) underwent a specific training about precariousness. Most of the ‘standard’ GPs had a low level of knowledge about homelessness and precariousness: only 1.2% of the sampled GPs knew the EPICES (Evaluation de la Précarité et des Inégalités Sociales de Santé dans les Centres d'Examen de Santé) score, which is a standard score in France for screening precariousness in general practice,46 ,47 28% of GPs knew the PASS system, which is the institutional system to ensure medical care and social help for people with no access to care in France; and 43% of GPs knew the telephone number for emergency housing service (Service Intégré Accueil Orientation; table 4).

Difficulties perceived by GPs in caring for HP

Social management when caring for HP emerged as the greatest difficulty for ‘standard’ GPs when treating the homeless (mean=3.95/5±0.98, on a Likert scale between 1 (no difficulty) and 5 (very high difficulties; table 5). Other significant difficulties were related to (in decreasing order): retrieving medical information (mean=3.78/5±1.05), management of patient's compliance (mean=3.67/5±0.99), loneliness in practice (mean=3.45/5±1.22) and excessive time necessary for consultation (mean=3.25/5±1.12; table 5).

Table 5

Divergent answers regarding how GPs could contribute to the care of HP

Views of GPs about how much they could contribute to the HP care were divergent, with a mean of 3.05/5±1.04 on Likert scale (between 1 for ‘not at all’ and 5 for ‘very much’). Some GPs gave explanations for this question: a significant part of them spoke about insufficient means, or the necessity to adapt the health system and primary healthcare organisation for permitting such a contribution for ambulatory GPs. Only two of them said that it was not a question concerning GPs or that some GPs would not accept to contribute because of their personal position.

Phase 3: explaining ‘standard’ GPs’ views about their contribution to healthcare for HP (qualitative analysis on a subsample of ‘standard’ GPs)

Characteristics of the subsample and interview

We included 14 GPs, who were differentiated by sex, age, type of practice, number of doctors in the office, secretary and having, or not, and received a homeless patient in the past. Interviews were mostly conducted at their offices (except one which was passed in a public area). The average duration of the records was 29 min. GPs who refused to participate explained that their refusal was because of lack of time for the interview. We obtained data saturation on the 13th interview, confirmed by the 14th. One GP delayed the interview and was not included because data saturation had been reached.

We identified four profiles of GPs:

  1. GPs regularly involved in and who had an experience in the care management of homeless (two GPs): they self-reported a good knowledge of homelessness and many relations to coordinate the care of homeless patients. They recruited homeless because of this profile.

  2. GPs who were exposed to homelessness and felt concerned about the problem (three GPs): they worked on particular deprived areas, or had mixed activities concerning homelessness or precariousness.

  3. GPs who were not exposed to homelessness but felt concerned (four GPs): they worked on suburb(s) areas and were not exposed to the roofless. They reported that they almost never received homeless patients without explaining why.

  4. GPs who were not exposed to homelessness and had negative views (five GPs): they worked also in suburban areas. They showed negative attitudes and views which could prevent homeless patients from consulting again these doctors.

Coding tree

We developed four main categories on this phase (see online supplementary file 2):

  • Health system organisation;

  • View of GPs about HP;

  • Role of GPs when caring for HP;

  • Care for HP by GPs.

The themes were derived from the data.

Conditions for ‘standard’ GPs to be involved in treating the homeless

The qualitative analysis showed that maintaining a stable follow-up was a major condition for GPs to contribute effectively to the care of HP (11 GPs, 26 verbatim; figure 3):

  • For some GPs, the presence of stable follow-up was the reason why they could contribute to the care of HP, as shown in this extract: “Yes [answering the question if GP could contribute, bring something positive to the health of homeless people], because most of the time I see, as I said, finally they come back […] They come back to see me […] they choose me as a family doctor”.

  • For other GPs, a stable follow-up was the most cited condition to enable participation in the care of HP: “it would be necessary to develop a kind of coercion which led them to a little loyalty. Here we can build something”.

  • The last GPs cited failure of follow-up to argue why they could not contribute to the care of HP.

Figure 3

Identified factors to influence the odds of building a stable follow-up of homeless patients (interview with ‘standard’ GPs, phase 3). GP, general practitioner; HP, homeless people.

As shown in figure 3, we identified three main factors that influenced the possibility of maintaining a stable follow-up: attributes of patients, care management conducted by GPs and health system organisation.

The factors that we identified in the speech of GPs were better linked to GPs' care management and to healthcare organisation, than to homeless patients themselves.

  • Concerning health organisation: social management, multidisciplinary practice on a team, backing and active outreach were mentioned as conditions to enhance the follow-up of homeless patients; social issues posed the greatest barrier for these GPs (access to social rights, and housing).

  • Concerning GPs: geographic proximity, attitude, trust in the relationship, education on health and adaptation in the care giving by GP were mentioned as conditions that could enhance the follow-up of homeless patients; negative attitudes and lack of active outreach for the homeless patients were the most barriers to the success of follow-up identified.

Having a stable follow-up relationship seemed to enhance views and attitudes of GPs. Success of a trust-based relationship and recovering social rights were all noted as the elements of a virtuous circle created by the follow-up.

Two others conditions were identified for GPs to effectively contribute to the care of HP:

  • Working in close relation with social workers (9 GPs, 12 verbatim);

  • Adaptation of GPs with better knowledge about homelessness (3 GPs, 4 verbatim).

These conditions seemed also linked to the success or failure of a stable follow-up as shown on figure 3.

Discussion

Main result: GPs could effectively contribute to the care for HP if we adapted the conditions of their practice

In this study, almost 80% of GPs who worked in the centre or the northern part of Marseille had already been exposed to homeless patients. Analysing the three parts of this study, we showed that conditions of GP's practice were a major factor which influenced the views of GPs regarding how they could contribute to care giving for HP. Indeed, in the quantitative part, ‘standard’ GPs felt the most difficulties in the care giving for the homeless due to: social management, retrieving medical information, management of observance of homeless patient, loneliness in practice, time necessary for consultation and complexity of care management. All these items could be improved by a better organisation of primary care, coordination and organisation of general practice. A study performed in the UK in 1996 has showed similar results, of the social problems as the first ones perceived by GPs when they cared for HP (90% of GPs agreed), followed by lack of medical records, complex health problems and alcohol or substance misuse.32 We did not directly ask the ‘standard’ GPs about substance misuse during the questionnaire, but the behaviour of homeless patients was not perceived as an important difficulty. However, during the phase 3 (qualitative), when ‘standard’ GPs perceived difficulties concerning patients with problems of substance misuse, it was a strong barrier for them to accept these patients. In the qualitative analysis performed on ‘standard’ GPs, we identified that a stable follow-up relationship between homeless patients and GPs was a central condition for GPs to be pertinent and effective in the care management of the homeless. This condition seemed to be closely linked to the characteristics of the health system organisation or characteristics of GPs' activity and behaviour than the patients themselves. After analysing the discourse of ‘involved’ GPs, we found that ‘involved’ GPs viewed the follow-up as something difficult to obtain, but a responsibility and challenge for them in the care giving for the homeless. So we can expect to improve this follow-up by adapting the conditions of practice for GPs. We need more data to explore if the conditions of practice influenced GPs or if the view and positions of GPs led them to choose this specific kind of practice. It would be interesting to complete these results by a study comparing a group of employed or mixed GPs and a group of private GPs. We also have to consider the differences between social aspects experienced by GPs and HP. It has been described that being recognised as different members of social classes, or cultural differences (called by E Carde48 ‘differentiation’), can influence the difficulties or views of health professionals about taking care of patients.49 ,50 We asked the involved GPs why they had engaged themselves in homelessness: only two of them spoke about their social origin (worker class) or familial past (alcohol addiction of his father). They mostly expressed a personal involvement due to moral values, and/or generated by their professional career. However, we did not have more details about social origin of the GPs who were interviewed, in phase 1 or 3, or who answered the questionnaire.

Strengths and weaknesses of this study

The choice of a mixed-methods design was justified here by the complex and sensitive nature of our research object. With the integration of multiple perspectives of different actors (GPs who were involved in homelessness and GPs with a standard practice) and quantitative and qualitative data collection, we aimed to provide a more complete and rich understanding of a phenomenon.36 ,38 ,51 ,52 Furthermore, the identification of areas of convergence or divergence among results can increase the rigour of the study and usefulness of the findings.53 Our ‘step-by-step’ process permitted to obtain a complete, rich and credible picture about the question of managing HP by GPs.54

Qualitative methods involve some subjectivity of the investigator during the analysis data process. Owing to financial and time constraints, we were unable to perform the analyses with another investigator. In order to limit the risk of irrelevant interpretations,55 the thematic coding was shared between the researcher and director of this research on each important step of its transformation; here, the use of a software (N-vivo) enhanced the rigour of the analyses.55 ,56 To enhance the rigour of our interpretation process, we discussed our conclusions with the participants of this research (interviewed GPs) at different times: during a meeting after the analysis of the firsts five interview for phase 1 and asking for a feedback about written results of phases 1 and 3. The reflexing process of the researcher was improved by listening to opinions and experiences of other external participants during the whole process of data collection and analyses and an involvement in a charitable association (Médecins du Monde) as a participant observation process throughout the analysis of phase 1. The intellectual effort and the multiple interpretations of actors were written as much as possible by the researcher.57 ,58 This progressive and interactive process has improved the method and the understanding of the results of each phase.

For the quantitative part, we chose to include GPs who worked in the suburbs which were more affected by precariousness, in order to address the problem on a concerned population and to follow a local interventional programme for the homeless in Marseille.59 The sampling process was rigourous so we can consider our sample to be representative of GPs working in the suburbs affected by precariousness. That can explain why our sample was not completely representative of French GPs: we do not want to extend these data to all GPs, but only to GPs who work in urban area and in low-income suburbs. We obtained a good level of response (74%) if we compare to similar design performed on close themes.31 ,32 There was no difference between respondents and non-respondents concerning work area and sex (the only data we had for non-respondents). However, we can suspect that GPs who did not answer the questionnaire had more negative views about HP and GPs role in their care. If the data collection had been diversified to improve the proportion of respondents, it could influence the response of GPs, in particular when it was conducted ‘face-to-face’. Using a standardised questionnaire and the same investigator should have reduced this limit.

Operational propositions for an efficient medical care in primary care for HP: how we can adapt the ambulatory condition of GPs' exercise

Regarding our results and data from other studies, we propose some specific solutions for GPs to improve access and continuity of care for the HP.

A grouped and multidisciplinary practice

The importance of a multidisciplinary and integrated approach (proposing, eg, housing on the same time than healthcare) for HP have already been described.25 ,60 Concerning specifically GPs: GPs' attitudes towards HP has been identified on a qualitative study as the major barrier to give access to primary care for HP.61 As it has been described, the behaviour of health workers with the homeless was modified when they worked in a multidisciplinary structure,62 we can expect that this kind of adaptation could be beneficial to personal experience of care management for GPs63 and enhance positive attitudes which can lead to more convenient access to care for the homeless.

Associate medical, social and psychological care, with the development of closer relations between GPs and social workers

Our study showed how social issues become a part of care when GPs have to care for HP. Other studies performed on precarious patients revealed the necessity to develop closer relationships between health workers and social workers,30 so we can expect that it is the same need when caring for homeless patients. In France, ‘microstructures’ have developed this multidisciplinary scheme, in general practice offices that integrates the presence of psychologist and social workers in a private medical office for 2 hours per week. These programmes concerned drug-addicted patients who lived in highly precarious conditions. This scheme enhanced access and continuity of care concerning prevention and chronic diseases for the patients who were included.64 ,65

Improving knowledge of GPs about precariousness and homelessness

In qualitative analyses, the lack of knowledge of GPs about social questions and the lack of experience of GPs in homelessness seemed to influence their behaviour and capacity to adapt their management for HP. A lack of knowledge about precariousness has already been highlighted in other French studies, where GPs identified training needs for multidisciplinary approach and social questions.31 ,66 ,67 The necessity to improve knowledge and develop training of GPs about homelessness has also been discussed by Riley et al24: for them, it is one of the major solutions (with support of primary care trusts) to make the ‘full integration of HP into mainstream primary care services’ occur. Both ‘standard’ and specialised GPs experienced difficulties when caring for the homeless, struggling to maintain a stable follow-up relationship. The ‘involved’ GPs tended to have more positive views on the homeless patients, they showed a better control of the complex situations of these patients and saw a successful follow-up relationship more as the responsibility of GPs to make it possible than as a condition for GPs to take care for HP.

Considerate non-medical time in remuneration of GPs

It is necessary to adapt the remuneration mode for private GPs, so that they consider the complexity of the care giving for homeless. This way they would be able to spend more time for active outreach, patient support, developing a care relation and coordination of care. These adaptations are described as solutions to improve the use of health system by the homeless, by enhancing care requests, providing them greater self-confidence and enhancing the trust of the homeless patients in the healthcare system.68

Develop a partnership between tailored and non-tailored systems

Lack of knowledge and difficulties for GPs to communicate with social or other specialised centres has been described in a French mixed study performed on GPs about precarious patients.31 Lester and colleagues, analysed the limits of tailored centres for the homeless, describing a similar model, which can ‘create a bridge between separation and integration, opening up access to mainstream care for the majority of HP and also providing immediate transitional primary healthcare and social care services through interested GPs’.30 As some GPs explained it in our interviews, dedicated structures, which answer to the social needs for HP, could be the first contact in care for homeless. The homeless could secondarily be sent to ‘standard’ GPs when they had recovered sufficient social rights and personal capacity to follow an adequate itinerary of care. Wright et al recall that a specialised general practice for HP is ideal to engage them in care and guide them in the ‘appropriate use of primary care’; after this, the patient can be ‘encouraged to register with a mainstream practice’. But Wright et al69 remember that ‘this switch can be difficult not only for patients but also for doctors when there is a strong personal commitment’. It is necessary to identify GPs who could engage in the care of HP, offer them training about precariousness, and foster closer collaboration their practices and those of the dedicated system. These tailored structures could also become a source for crisis management or a support for GPs who need assistance in the care managing of HP.

Conclusion

GPs could effectively contribute to the improvement of the HPs health, if organisational and material conditions of their practices were adapted properly. It is necessary to develop a grouped and multidisciplinary offering, permitting an integrated medicopsychosocial approach. These results will enable the construction of a new model of primary care organisation to improve access to healthcare for HP.
