Abstract

Objectives Patients with acute symptoms present not only to general practitioners (GPs), but also frequently to emergency departments (EDs). Patients’ decision processes leading up to an ED self-referral are complex and supposed to result from a multitude of determinants. While they are key providers in primary care, little is known about GPs’ perception of such patients. This qualitative study explores the GPs’ view regarding motives and competences of patients self-referring to EDs, and also GPs’ rationale for or against physician-initiated ED referrals.

Design Qualitative study with semi-structured, face-to-face interviews; qualitative content analysis.

Setting GP practices in Berlin, Germany.

Participants 15 GPs (female/male: 9/6; mean age 53.6 years).

Results The interviewed GPs related a wide spectrum of factors potentially influencing their patients’ decision to visit an ED, and also their own decision-making in potential referrals. Considerations go beyond medical urgency. Statements concerning patients’ surmised rationale corresponded to GPs’ reasoning in a variety of important areas. For one thing, the timely availability of an extended spectrum of diagnostic and therapeutic options may make ED services attractive to both. Access difficulties in the ambulatory setting were mentioned as additional triggers for an ED visit initiated by a patient or a GP. Key patient factors like severity of symptoms and anxiety also play a major role; a desire for reassurance may lead to both self-referred and physician-initiated ED visits. Patients’ health competence was prevailingly depicted as limited, with the internet as an important influencing factor. Counselling efforts by GP were described as crucial for improving health literacy.

Conclusions Health education could hold promise when aiming to reduce non-urgent ED consultations. Primary care providers are in a key position here. Amelioration of organisational shortages in ambulatory care, for example, limited consultation hours, might also make an important impact, as these trigger both self-referrals and GP-initiated ED referrals.

Strengths and limitations of this study

  • This qualitative study explores the perspective of primary care providers on self-referred and physician-initiated emergency department (ED) consultations.

  • Interviews gave detailed and profound insights into decision-making processes and the underlying complex set of considerations.

  • A particular feature of the study is the incorporation of the provider perspective on both patients’ and physicians’ motivations leading up to ED consultations.

  • Deriving estimations of patients’ motives from provider interviews is prone to conjecture, hence a measure of caution is warranted in regard to inferences.

  • Although ED crowding is an international phenomenon, transferability of study results to other settings may be limited, as characteristics of the healthcare system and the specifics of the metropolitan location have influence on consultation patterns.

Introduction   

Patterns of healthcare utilisation are in transition. Especially, in metropolitan settings like Berlin, patients often use more than one care sector and may present either to their general practitioner (GP) or to a hospital emergency department (ED) in case of acute symptoms.1 2 Out-of-hours care in Berlin is principally provided by statutory health insurance physicians. Services include a triage and counselling hotline, a home visit service and two hospital-based urgent care centres. More severe emergencies are handled by the Fire Brigade’s ambulance rescue service. However, patients are at liberty to self-refer to a hospital ED any time, without having to call a hotline or consult a GP before. While part of these patients may in fact be severely ill and subsequently require inpatient treatment, a large proportion of ED visits results in exclusively ambulatory treatment.3 ED utilisation by non-urgent patients represents a growing phenomenon, contributing to crowding and time shortage in ED workflow,4 5 as such patients tie up resources and may even endanger timely treatment of critically ill patients.6–9 Scientific data suggest a detrimental effect of ED crowding and subsequent longer ED waiting times on hard endpoints like short-term mortality of both patients admitted to hospital and ED outpatients. Thus, the potential impact of efforts to reduce ED utilisation by non-urgent cases is substantial, as such cases are considered to account for a high proportion (up to >60%) of ED patient load, depending on study and setting.10–12 In Germany, the current true total number of ED treatments is quite difficult to estimate, as there are no official comprehensive nationwide statistics.13 However, the data sources available suggest a steady rise in total ED consultations over a decade,14 and also a growing proportion of ED outpatient treatments.14 15

Consultation reasons of self-referring patients have been evaluated in a number of recent studies,10 16–19 and utilisation is considered to result from a complex set of motivations, encompassing a lack of connection to continuous primary care, the convenience of low-threshold ED access or the surmised availability of advanced diagnostic options in the hospital setting.19–21 Nescience concerning alternative care facilities for acute illness—or the lack of such alternative offers in the ambulatory care sector—may also play a role for patients self-referring to ED,13 22 as well as patients’ health literacy, which is an important prerequisite for appraising their own symptoms adequately.23 24

There are comparatively few current publications on the views of primary healthcare providers18 21 25–27 regarding patient-initiated ED consultations, which is surprising considering the GP’s key position in patient care and also her or his potentially substantial influence on decision-making.28

However, there is an important additional trigger of ED visits that is less frequently focused: utilisation does not only depend on patients’ self-referral behaviour, but may also be initiated by primary care physicians referring some of their patients to a hospital ED. Interestingly, there is very limited literature concerning GPs’ decision-making processes when ruling for or against referrals. However, previous studies suggest that knowledge about a patient’s personal background as well as the physician’s gut feeling play a role, besides the mere assessment of signs and symptoms.29 Personal characteristics of GPs, like cautiousness versus readiness to take risks, are as well discussed as influencing factors on referral decisions,30 31 as are social issues and other factors of contextual pressure.32 Considering the literature, it is also quite unclear to what extent GPs may potentially decide to refer non-urgent cases to EDs, and why they might do so.

In this study, we therefore wanted to investigate the twofold problem of self-referral and GP-initiated referral to EDs. The aim was to better understand the motivations and decision-making processes of patients and GPs in regard to ED self-referrals and physician-initiated referrals by a qualitative evaluation of the provider perspective. Looking at the patients’ and GPs’ motives, we considered it highly interesting to further assess these in regard to conceivable parallelism, as such has not yet been scientifically addressed to our knowledge. The exploration of this aspect therefore constitutes a particular aim of this study. Furthermore, the situation of self-referrals being discussed as a contributor to ED crowding33 leads up to the very interesting question of whether patients are actually in a capacity to adequately decide on the appropriateness of utilisation, for example, depending on individual health literacy.24 This is why we decided to additionally focus on this aspect.

Consequentially, the main research questions for this study were as follows: What do GPs think about their patients’ motives for self-referring to an ED? How do GPs judge patients’ capacity to make an adequate decision for or against visiting an ED in acute situations? What are GPs’ considerations when initiating referrals to such facilities themselves? As we aimed to gather in-depth insights and thoroughly explore GPs’ views, a qualitative study design was deemed appropriate.

Methods

Study context

This qualitative interview study is a module of the mixed-methods research project ‘EMACROSS’, part of the Berlin-based health services research network EMANet. EMACROSS aims to evaluate the characteristics, motivations and utilisation patterns of patients consulting one of eight EDs in Berlin-Mitte, the district in the city centre of Berlin, Germany. For further details of rationale and design, please refer to the German Clinical Trials Register.34 The quantitative study module consists of a repeat questionnaire survey of ED patients complemented by an analysis of hospital records. While this quantitative part of the project focuses on respiratory diseases as a model condition, we did not restrict our research questions to a single health problem for the qualitative study module presented here. Study design and results are reported in line with the Standards for Reporting Qualitative Research guidelines.35

Sampling and participants

Participants were sampled purposively. We aimed to achieve a diverse sample in regard to age groups, length of professional experience and number of patients per practice. We aimed to diversify our sample according to a set of characteristics that were considered to have a possible influence on the interviewee’s stance, in order to cover a wide spectrum of views. Physician gender has been described as an influencing factor on referral decisions, as well as personal risk tolerance.30 From a theoretical point of view, risk tolerance might be conceivably associated with characteristics like length of professional experience and physician’s age, while there is no literature to prove or discard this. Professional experience might also have influence on the GP’s insight into patients’ motives, which is grounded on her or his personal experience with a larger—or smaller—number of patients treated in the course of her or his career. GPs were recruited (SO) from the GP research network of the Institute of General Practice which is also part of the EMANet consortium. Potential interviewees were sent an information sheet on the study; participants were selected from the pool of responders. The sample consisted of nine female and six male GPs, details of the sample are provided in table 1.

Data collection

A semistructured interview guide with open questions was developed to obtain in-depth, detailed accounts of GPs’ perspectives.36 The basic structure of the first draft was based on the literature16–19 21 22 24 31 and the researchers’ knowledge of the subject (SO and FH; SO is a health scientist and FH is a GP). Questions were intended to generate interview content suitable to answer the study research questions. The guide was then discussed in an interdisciplinary working group for qualitative methods and subsequently adapted. After a first set of interviews, it was revised again according to the experiences gained. Final structure of the interview guide was determined after the third interview (see excerpts in box 1). Interviews were conducted in the interviewees’ practices in Berlin between July and September 2017 (SO). Participants’ written informed consent was obtained a priori. Interviews were audio-recorded and transcribed verbatim (SO), all transcript data were pseudonymized. To document atmosphere, interaction, particularities and potential disturbances, field notes were taken throughout the interview process (SO). Data collection was concluded once no more new topics and viewpoints emerged and content therefore was deemed saturated.37 This was achieved after 15 interviews.

Box 1

Examples of questions from the interview guide

What do you think are the motives of patients for seeking care in an ED?

What do you think about your patients' capacity to make an adequate decision for or against visiting an ED in a case of potential emergency?

Which patients do you refer to the ED and how do you decide?

What are your intentions when referring there?

Can you imagine situations in which you might send patients to the ED who are not severely or threateningly ill?

  • Questions could be individually adapted to the conversation flow of the respective interviews. Complete interview guideline is available from the authors on request.

  • ED, emergency department.

Data analysis

We conducted qualitative content analysis.38 This approach was favoured due to its suitability for describing and understanding social reality, while other conceivable methods (eg, grounded theory) might be more appropriate for purposes of theory generation.39 A first basic structure of the coding tree was based on the topics of the interview guide, which itself had been the result of a deductive process. Additional categories were derived from the interview material inductively during coding. The combination of both approaches allows taking into account both theoretical considerations and aspects and perspectives voiced in the interviews.40 41 For all categories, clear definitions, coding rules and anchor examples were formulated. SO reviewed and coded all interviews. For transcribing, coding and analysis, the qualitative data management software MAXQDA (V. 12 and 2018) was used.

Strategies to enhance trustworthiness

The category system was repeatedly reviewed and discussed within the research team and additionally with an experienced qualitative researcher (MS) from EMANet not directly involved in data collection and analysis. Independent coding was performed by another researcher (FH), results and potential discrepancies in interpretation were discussed in the team. To further prevent involuntarily influencing interpretation of material by implicit expectations and presuppositions of the researchers involved,42 coding and interpretation were peer-reviewed within the interdisciplinary qualitative methods working group to enhance credibility.

Patient and public involvement

Patients were not involved in the design and conduct of the study. Participants were asked whether they would like to receive a report on the study’s findings. Study results will be disseminated to interviewees who desired such.

Results

In the following results section, we first present data on patients’ motives for self-referral and GPs’ referral motives, structured by common themes that emerged during analysis. A further subsection will demonstrate the results regarding GPs’ assessment of patients’ capacity to decide adequately about an ED consultation. The research aim of exploring possible congruities of motives on the patient and physician side will be addressed in the discussion section.

Patients’ motives for self-referral and GPs’ referral motives

Three principal themes emerged during analysis of interview data concerning GPs’ views of patients’ presumed self-referral motives and the passages on GPs’ reasons for referrals to EDs: ‘attractiveness of emergency department care’, ‘patient-specific factors’ and ‘organisational issues’. Corresponding quotes are presented in table 2.

Attractiveness of emergency department care

Patients’ motives for self-referral

Interviewed GPs considered the attractiveness of the ED due to availability of timely and comprehensive diagnostic and treatment options—when compared with the services usually provided in GP practices—a major factor for self-referred ED utilisation. Some stressed that patients may believe in better, safer and more advanced procedures provided in the hospital. Further occasionally mentioned factors were the constant availability of the ED and the surmised presence of specialists there, when compared with generalist services provided in primary care. Convenience reasons, apart from the aforementioned comprehensiveness and ready availability of diagnostics, were also addressed, but altogether seemed not to be considered a pivotal trigger for self-referrals by most interviewees. A few mentioned surmised consultation reasons like patients’ desire to avoid the hassle of making an appointment at a doctor’s office. Some GPs also presumed that in case of practice closure at their own practice, certain patients might prefer the ED to spare themselves the trouble of arranging a consultation at an alternative GP practice. The phenomenon of patients seeking out-of-hours ED care specifically for convenience reasons (eg, after finishing work) was also addressed critically, but only by few participants. Concerning appropriateness of ED utilisation, a number of GPs criticised a questionable and excessive sense of entitlement in some patients, particularly regarding the availability and responsibility of the ED in non-emergency cases.

GPs’ referral motives

Many GPs reported to send patients to the ED if they would consider them in need of diagnostic procedures or treatment not available in the primary care setting, for example, for confirmation or exclusion of a suspected—and potentially threatening—diagnosis. Some GPs especially stressed the fact that hospital infrastructure might allow for a more speedy workup. For a majority of GPs, EDs are the ‘port of call’ where to send patients if they would want them admitted to an inpatient care.

Patient-specific factors

Patients’ motives for self-referral

In the GPs’ experience, acute onset or perceived rapid deterioration of symptoms were important triggers for self-referral. This aspect was mentioned in a majority of interviews. Such ED consultations were judged by the interviewees as legitimate, as they may indicate ‘real emergencies’. Many of the interviewed GPs stressed the important role of ‘perceived severity of illness’ and ‘anxiety’ as reasons for visiting the ED, especially in chronically ill patients. Anxiety in a subjectively threatening situation was frequently described as influenced by patients’ personality traits, for example, a high sensitivity to physical symptoms. The issue of anxiety triggered or augmented by media reports about serious illness or dangerous complications was discussed in this context. A number of interviewees considered this especially a problem in younger patients. GPs surmised that such patients visit the ED for quick and thorough reassurance, a second opinion on their symptoms or other kinds of health information, while in fact not being in any dangerous situation health-wise. Other patient-specific self-referral reasons mentioned in the interviews encompassed a possible lack of trust of the patient in her or his GP, or even doubt about the primary care provider’s competency.

GPs’ referral motives

A majority of GPs reported to refer in cases of acute and severe symptoms, a subject already broached in the ‘attractiveness of emergency department care’ section above. However, it was notable that domestic care situation was another major point of consideration for some of the interviewed GPs when deciding for or against hospital referral, as well as factors like frailty or limited mobility, which might impede adequate outpatient management, even in cases where the health situation would usually not require an ED referral.

Organisational issues

Patients’ motives for self-referral

Access problems in the ambulatory care sector were quite frequently addressed in the interviews. GPs problematized the limitation of consultation hours in primary care and in specialist doctors’ offices, driving patients to the ED off-hours in lack of an alternative. Notably, this seemed not to be perceived as a ‘convenience issue’, but as a problem of availability. In the GPs’ experience, patients with acute symptoms or increasing worries feeling in need of urgent investigation or reassurance might see no other option than presenting to an ED off-hours. Length of appointment waiting times at specialist practices was also problematized: GPs criticised that some ambulatory medical specialists’ schedules may be booked out for months in advance. Patients’ hope of being seen by a physician of the desired specialty more quickly —or at all—might then drive them to an ED self-referral. It was also mentioned that the ED offers a low-threshold access to healthcare for patients not regularly attached to a GP practice.

GPs’ referral motives

Some GPs reported to more frequently refer patients to hospital prior to the weekend or on days when practices might close, and no further outpatient diagnostic investigations might be possible on the day or the following days. One GP indicated that she sometimes felt forced to refer acutely ill patients to the ED if she would not succeed in arranging a necessary appointment at a specialist’s practice.

Patients’ capacity to make an adequate decision

Interviewees’ views regarding the capacity of their patients to make a proper decision on where to go with a perceived health problem were quite heterogeneous. Corresponding quotes are presented in box 2. In the majority of the interviews, GPs tended to judge patients’ general ability to assess their own symptoms adequately as poor, and many were of the impression that such competences were currently in decline. The perceived deficiency in judgement of patients’ own health status was frequently stressed as an important reason for non-urgent ED consultations. The internet as a source of health information was seen very critically in this context, as online information might have a negative impact on patients’ disease perception. Patients’ ability to adequately process and assess information consumed from media sources was frequently deemed limited. Some interviewees stressed the potential escalating effect of frightening information, especially on already anxious patients. The widely perceived lack in patients’ competence in regard to health matters despite abounding information was frequently attributed to a deficiency in health education and even basic medical knowledge especially ascribed to younger patients. Some GPs remarked that in addition to individual health literacy, patients’ respective social environment may also have great influence on how they perceive and appraise their symptoms. The crucial role of the doctor-patient relationship and the importance of the GP as a key health educator were also stressed. Counselling and health education by the individual patient’s GP were mentioned as having a potentially de-escalating effect, as these may help patients not to overinterpret their symptoms. Some GPs also stressed the importance of educating their patients about the function of the ED versus the GP after a non-urgent visit to avert similar events in the future.

Quotes: patients’ capacity to make an adequate decision

‘Not very good, I would say […]. Patients cannot assess this […]. The patients have zero competence there.’ (GP 9)

‘[…] as far as the younger patients are concerned, only 25 percent make the right decision. The general direction is: emergency services are visited much too quickly or hectically, although in fact it may not be really necessary.’ (GP 8)

‘Like I said, nowadays they ‘google’ and then: ‘This is very bad, can get very bad […] and this must be resolved on a Saturday or Friday evening.’ (GP 8)

‘[…] the older ones […] I rarely see them going there without an emergency, I say. […]. They more often go to EDs in cases where I would say ‘Well, these are indications that actually belong in an ED […].’ (GP 15)

‘I think, old patients, the old grandma, the grandpa, who thinks three times before he decides to visit a doctor. He’ll wait until it doesn’t work anymore.’ (GP 10)

‘In this context it is important to me to evaluate the GP’s role differently. I believe that we are the ones who have long-standing and in part intensive relationships with our patients. We are probably the ones who can achieve the most, because we can steer the patients strongly, much better than any other medical specialist can.’ (GP 5)

‘The more I explain, the more the patient knows. The more he knows, the more competent he becomes […]. If I explain well, people are more competent. And health education is important […].’ (GP 1)

‘[…] the most important thing is de-escalation policy […], to put banalities into perspective. Not to over-interpret things and not to stir up anxieties. Because this eventually drives people to the doctor […].’ (GP 1)

Discussion

In the interviews, GPs depicted a wide spectrum of factors potentially influencing their patients’ decision to visit an ED, and also their own decision-making process in possible referrals. Common themes concerned the attractiveness of EDs due to constant and instant availability of an advanced diagnostic and therapeutic spectrum, and patient-specific factors like severity and acuity of symptoms as well as health-related anxiety and a need for reassurance. Organisational shortcomings of practice-based ambulatory care, for example, appointment problems, were also raised as potential triggers for ED utilisation. Patients’ health competence and capacity to decide adequately were frequently depicted as limited, and the impact of health information derived from media sources was seen very critically.

Corresponding factors in patients’ and GPs’ decision-making

Severity and acuity of symptoms

Justifiably, severity and acuity of symptoms were seen as major triggers of ED consultations, as depicted in the ’attractiveness of emergency department care’ and ‘patient-specific factors’ themes. Much has been written about patients and GPs turning to the hospital sector in cases of severe or potentially dangerous symptoms,10 18 43 44 which is not surprising—and altogether adequate—considering the ED’s purpose. However, in the GPs’ view, both reasons for self-referral and physician-initiated referral go far beyond the medical question ‘emergency or not’, and it is very interesting that a number of additional considerations may actually also correspond to each other. As such, conceivable parallel factors have not been discussed before in-depth, they warrant special emphasis.

Perceived shortage of alternative options

Patients as well as GPs might turn to the hospital sector for—real or perceived—lack of alternative ports of call for timely diagnostic procedures or specialist consultations. Access problems in the primary care sector have been described as an important trigger for ED visits in a number of previous works.45–47 In our study, unavailability of practice services of both GPs and medical specialists during weekends and off-hours was problematized as leading to both self-referred and physician-initiated ED visits. Crowding of specialist practices may also make GPs feel forced to refer patients. The identification of lack of access in the outpatient sector as a key factor for patients’ decision-making is in line with the results of Durand et al,21 who interviewed ED healthcare professionals and patients. The situation of patients visiting EDs because they do not have a regular GP—or may not be able to visit her or him for a variety of reasons—was also described by others.17 27

Internationally, a variety of measures to improve out-of-hours care for less urgent acute patients have been evaluated. In the Netherlands, for example, EDs and GP cooperatives have created Emergency Care Access Points (ECAP), where patients are triaged under GP supervision and steered to either GP or ED care, thus avoiding direct patient self-referral to EDs.48 This concept has been shown to reduce ED consultations considerably,49 and evidence for GP cooperatives as an effective concept is convincing.50 A ‘single-desk’ access point model for acute care comparable to the ECAP has been proposed for Germany in a recent expertise by the government-appointed ‘Advisory Council on the Assessment of Developments in the Health Care System’.51 Some authors have however raised concerns regarding the cost-effectiveness of entirely new service models for out-of-hours care, as such might ultimately increase demand, while simple extension of GP opening hours might be a resource-sparing alternative.52

Desire for reassurance and the role of health literacy

A wish for reassurance emerged as another important factor that might prompt both a self-referred and a GP-initiated ED consultation. For one thing, GPs considered health-related anxiety a principal reason for ED self-referrals, as patients perceive themselves as emergencies urgently needing attention. Anxiety as a driving motive for ED consultations was described in a substantial number of international studies.17 21 22 53 A state of anxious concern regarding patients’ general health—besides the worry caused by unclear acute symptoms—was described as an important factor. Correspondingly, the GPs in our sample stressed both the importance of the subjectively threatening acute symptoms and also the general trepidation in regard to potential serious disease or complications. This corresponds to a recent survey by Scherer et al.11 Regarding physicians’ decision-making, the motivations attested to anxious patients are reflected in the doctors’ desire for having the patients’ care ensured while not being available as a provider, for example, when considering whether to admit patients prior to the weekend. Interviewees described how they would consider factors like patients being elderly, frail or alone at home—situations in which physicians might feel anxious that ambulatory management may not suffice to ensure comprehensive care. As already mentioned, previous studies have also discussed the role of factors like GPs’ personal experience and personality traits—like level of cautiousness and apprehensions about the consequences of the decision not to admit.31 Interestingly, such aspects were not overtly addressed by our sample, but may be veiled in descriptions of decisions to refer to EDs to assure care, for example, prior to weekends.

The few available published studies on GPs’ reasoning when deciding about a potential referral suggest that decisions usually result from a complex process of consideration, taking into account many factors besides the medical necessity.31 44 Dempsey and Bekker32 described such processes as an attempt at integration of conflicting consequences for many stakeholders in time-pressured situations, which seems an apt conclusion when looking at our results. Interestingly, GPs in our interview sample seemed to perceive the considerations of patients self-referring to EDs because of access issues or a desire for reassurance as essentially legitimate, when compared with reasons of mere convenience. Understanding for anxiety-driven self-referrals has been correspondingly expressed by GPs in other studies.18 The finding that both factors also feature prominently in the physicians’ decision-making may explain such judgement. Interestingly, while there is a considerable amount of scientific literature on the issue of non-urgent self-referral, the role of GP referrals of patients with non-urgent complaints has not been much evaluated or discussed before, and there is no scientific data quantifying the extent of this phenomenon. Previous studies have suggested that hospital referral rates vary considerably between GPs,54 which cannot be comprehensively explained with the body of evidence available.55 Concerning the underlying reasoning actually leading up to a referral, our data provide a unique insight into potentially underestimated triggers of ED consultations.

While interviewed, physicians ascribed a comparably minor role to convenience issues; the main criticism was notably directed at health literacy and patients’ competence to assess their own symptoms, and therefore at the cognitive and emotional process leading up to the decision to consult, rather than at the decision itself. In the interviews, patients were frequently attested deficiencies in adequately appraising their situation as dangerous or harmless. In this context, internet health information was seen as potentially deleterious to already scared patients. Concern in healthcare professionals about ‘disinformation despite information overflow’ has been reported by others.56 Correspondingly, a higher utilisation of EDs and hospital services by people with low health competence could be shown in international studies,23 57 and also a larger proportion of potentially avoidable consultations in such patients.24 In our interviewees’ statements, the conceived preponderance of younger patients in regard to low health competency and subsequent non-adequate ED visits was quite notable. Other works seem to hint at the genuineness of this perceived phenomenon, finding a higher rate of non-urgent consultations in the young in their quantitative evaluations.58 59 While higher internet use and consumption of online information in younger age groups is an undeniable fact,60 the causal role of media consumption on the path to low health competency voiced in some of our interviews must be considered conjecture, as there is no scientific corroboration. However, the statements relate a ’felt’ connection between two modern-age phenomena. GPs stressed their own role as key health educators in this context. Interestingly, the presumed phenomenon of younger patients constituting a main group of non-urgent ED utilisers is not consistently supported throughout the literature, and other works have stressed the role of chronically ill patients as a high-utilising population.17 61 However, as qualitative studies are not suited to give any estimation regarding prevalence or proportions, we can only relate the impression gained from our interviews here. A conceivable explanation for the comparable dominance of the aspect ‘young people’s consultations’ may be that ED visits by the chronically ill could be perceived by the GPs as altogether legitimate, whereas non-urgent ED consultations by the young—and otherwise healthy—might be more ’memorable' when prompted to think about self-referrals, as they were judged critically.

Strengths and limitations

Our study paints a complex and comprehensive picture of patients’ motives for self-referral and GP referral motives from the provider perspective. Interviews gave detailed and profound accounts of GPs’ views of their patients’ motives and their own thought processes leading to ED referrals. Our results allow relating and comparing both sets of motivations and corresponding decision-making processes.

We are aware that deriving patients’ motives from provider interviews poses the problem of secondhand assumptions and conjecture. However, there also are some important benefits of this approach: first, GPs have experience with a very large number of patients and are not centred on a single case, allowing them a more global and analytical perspective. Second, providers intimately know the mechanisms and structures of the healthcare system, which is important to understand the process of utilisation. As GPs frequently care for their respective patients for many years, they know a lot about their thoughts and decision processes, and are also able to give insights into the role of health competencies. Naturally, this perspective is limited to patients who at least occasionally visit GP practices, and not all ED patients may do so.

Researcher and interviewer bias can never be completely excluded, but we strived to minimise any unwitting influence of our own hypotheses and opinions by constant reflection and peer-review of our research process. Additionally, independent coding was performed to enhance reliability and reveal alternative interpretations. Concerning limitations of our study, the rather cognitive nature or our interview questions should be addressed, as this could have potentially impeded interviewees from revealing deeper layers of personal thoughts and feelings. A member-check was not performed. The composition of the sample could also have influenced the results: only physicians in an age range of 44–64 years were interviewed, and we do not know whether younger GPs might have different reasons for referral. However, as the mean age of GPs in Germany is 55 years,62 our sample reflects the demographics of the target group.

Transferability to other settings is also an issue. The metropolitan setting of Berlin might have influenced the results, as healthcare structures are abundant and close-meshed. This is true for both EDs and physicians’ practices—patients’ choices might be much more limited in rural areas, which could have an impact on decision-making. However, earlier studies hint at a fundamental concordance of considerations in less urbanised settings.13 It must also be noted that access to healthcare services depends markedly on the structures and organisation of the local and national health system, and our results may reflect the specifics of our setting. In Germany, access to GPs, specialist practices or EDs is not restricted in any way, patients can choose freely. Some practices may be based on appointment-only; others might accept walk-ins. Germany has neither a gatekeeping system nor rules for attachment of patients to specific practices, except within some disease management programmes. Therefore, in other settings, consultation patterns might differ.

Conclusions

In the providers’ view, patients’ decisions to self-refer to EDs result from a complex set of motives. Besides the overt central role of severity and acuteness of symptoms, a perceived lack of alternative care offers and a prevalent desire for reassurance emerged as important factors that are mirrored in the GPs’ considerations when deciding about ED referrals. If a patient’s decision is based on a rationale corresponding to the physician’s own reasoning, an ED self-referral may be perceived as comparably legitimate by providers, even if the case may not qualify as a genuine emergency in a medical sense. In this regard, it must be stressed that ‘emergency markers’ like symptom severity and urgency can only partly explain ED consultations, as decision-making for both self-referrals and GP referrals is the result of an intricate set of considerations of medical, psychological, social and organisational nature.

Concerning the desire for reassurance, physicians ascribe a potentially escalating effect to information obtained from the media and the internet, especially in younger patients. A focus on appropriate health education could hold promise when aiming to reduce non-urgent ED consultations. In this regard, primary care providers are in a key position that may allow them a special opportunity to actually make a difference.

Organisational restrictions of the healthcare system—like appointment problems and practice closure times—also strongly influence both patients’ and GPs’ decision-making. Provisions to ensure easier and faster access to diagnostics in the ambulatory sector might make both patients and GPs more comfortable with a decision not to immediately turn to the hospital sector. Naturally, the feasibility, acceptance and impact of such measures need to be evaluated in future studies.
