Objectives Addressing the social determinants of health has been identified as crucial to reducing health inequities. However, few evidence-based interventions exist. This study emerges from an ongoing collaboration between physicians, researchers and a financial literacy organisation. Our study will answer the following: Is an online tool that improves access to financial benefits feasible and acceptable? Can such a tool be integrated into clinical workflow? What are patient perspectives on the tool and what is the short-term impact on access to benefits?
Methods An advisory group made up of patients living on low incomes and representatives from community agencies supports this study. We will recruit three primary care sites in Toronto, Ontario and three in Winnipeg, Manitoba that serve low-income communities. We will introduce clinicians to screening for poverty and how benefits can increase income. Health providers will be encouraged to use the tool with any patient seen. The health provider and patient will complete the online tool together, generating a tailored list of benefits and resources to assist with obtaining these benefits. A brief survey on this experience will be administered to patients after they complete the tool, as well as a request to contact them in 1 month. Those who agree to be contacted will be interviewed on whether the intervention improved access to financial benefits. We will also administer an online survey to providers and conduct focus groups at each site.
Ethics and dissemination Key ethical concerns include that patients may feel discomfort when being asked about their financial situation, may feel obliged to complete the tool and may have their expectations falsely raised about receiving benefits. Providers will be trained to address each of these concerns. We will share our findings with providers and policy-makers interested in addressing the social determinants of health within healthcare settings.

Strengths and limitations of this study
Multisite study involving clinics in two provinces.
Pragmatic implementation of a novel tool in the real world of busy primary care clinics.
Mixed-methods evaluation, using several data sources to triangulate findings.
Convenience sampling method for patients.
A short follow-up period (4 weeks after intervention) may underestimate the impact of the novel tool.
The WHO defines the social determinants of health (SDOH) as ‘the conditions in which people are born, grow, live, work and age’, and include the material resources a person has available that are necessary to live a healthy life.1 SDOH have been identified as a key reason for health inequities between different individuals and groups within a population and help explain differences in access to health services.2 The WHO Commission on Social Determinants of Health, the British Medical Association and the Canadian Medical Association have all called on the health sector to play a greater role in addressing the SDOH through implementing and evaluating new interventions and serving as a link between disadvantaged communities and social and community services.3–6 Primary care settings in particular are uniquely opportune spaces to take action.7 Primary care providers follow patients longitudinally are community based and often have knowledge of the broader familial and social contexts that shape health and disease.8
One of the most important SDOH is income security: a person’s actual, perceived and expected income.9 10 Income influences the presence and severity of most health conditions. People living in poverty may have difficulty paying rent,11 affording nutritious food,12–15 affording transportation and engaging with others socially.6–9 Many studies have shown that economically marginalised people tend to live shorter lives, experience a greater burden of disease and disability and rate their health status as worse than the wealthy.16–21 One aspect of income security is access to financial benefits.
There are currently few, rigorously evaluated SDOH interventions deployed in clinical settings that have been found to improve material conditions and subsequently the health of individuals and families.22 23 Welfare benefits advice services within general practices in the UK have been found to increase the income of recipients, although improvements in health were not assessed in most studies.24 Similarly, a health promotion service in Toronto, Canada has been developed to assist patients with income security within primary care settings, but the impact has not yet been reported.25 Several studies in the USA have demonstrated the effectiveness of clinic-based interventions at connecting patients to community resources to address SDOH. In Boston, the Well-child Care Visit, Evaluation, Community Resources, Advocacy, Referral, Education study took place in paediatric clinics.26 A waiting room survey screened for social needs and members of the healthcare team provided information on community resources, adding less than 2 min to the visit. At 1 month, 20% of the intervention group parents reported contacting a referred community resource versus 2.2% of parents in the control group.27 The online tool, HelpSteps,28 29 screens for a much larger number of social needs, taking on average 25 min to complete, with 90% of users identifying at least one social need and 96% reporting they would recommend its use to a friend or peer.30 The California iScreen study,31 also tested in paediatric clinics, used the Health Leads32 model and found that social needs can be identified and providing patient supports led to improvements in parent-reported child health.33 In Canada, a paper-based clinical tool has helped train physicians and other health providers to consider poverty as a health issue.34 This tool has been adapted by the College of Family Physicians of Canada for use in all provinces and territories. No studies to date have evaluated the impact of this tool on providers or patients.
Our study focuses on developing, implementing and evaluating an online tool in primary care settings that focuses on access to financial benefits. This study emerges from an ongoing collaboration between family physicians, researchers and a charitable financial literacy organisation, Prosper Canada.35 This paper describes the protocol for this mixed-methods study that will evaluate the implementation and impact of this online tool. Our study will assess: (1) whether health providers find using a tool to address access to financial benefits in a clinical setting feasible and acceptable; (2) lessons learned and opportunities identified to integrate the tool within the regular workflow of primary healthcare organisations and (3) feedback from patients using the online tool and the short-term impacts on awareness and access to benefits.
This study will use qualitative and quantitative methods to evaluate the feasibility and acceptability of using an online tool in primary care to address access to financial benefits. The online income tool will be implemented at six primary care clinics, three in Toronto, Ontario and three in Winnipeg, Manitoba. All sites serve large numbers of patients with complex health needs and low socioeconomic status (table 1).
The intervention is centred on an online tool that guides users through 12 demographic and income-related questions and subsequently generates a customised list of relevant provincial and federal government benefits and tax credits. The initial screening question ‘Do you ever have difficulty making ends meet at the end of the month?’ has been validated in similar settings to identify patients who live below the Canadian poverty line with 98% sensitivity and 64% specificity.36 Further questions were determined based on the eligibility criteria for various federal and provincial benefits and tax credit programme. The tool was first used at a community health centre and with a family health team in Toronto for 1 month to identify technical problems. Following feedback sessions with providers, modifications were made to the tool to improve its overall design for use in this study.
An orientation session will be held at each site to introduce primary care providers to the tool and enrol them in the study as participants. Following this session, the tool will be implemented for a 3-month period. The tool can be used by any member of the healthcare team, including physicians, nurses, nurse practitioners, patient navigators and social workers. Each site will have some flexibility in how the tool will be implemented into the routine workflow of patient care, based on input from providers at the site. Health providers will be encouraged to use the tool with every patient seen. The tool can also be used in an opportunistic way when patients share a health concern that is linked to low income. Patients who consent to participate in the study can then use the tool with their health provider. At this time, study sites do not have a formal, systematic way to identify low-income patients. To minimise bias by providers or reception staff, all patients who present for care in these clinics will be approached. This intervention was not randomised because excluding low-income patients from receiving information on eligible benefits and accessing additional income supports would be unethical. Moreover, the topic may come up in any given appointment depending on the nature of the visit. Given the limited time during appointments at some sites, family physicians will screen patients for low income and refer them to a care coordinator (eg, social worker) to complete the tool (figure 1).
The six clinics testing the tool will introduce the pilot study to healthcare providers and interested providers will be consented to participate. We will aim to have a diverse group of healthcare professionals use the tool with patients including family physicians, nurse practitioners, social workers and patient navigators.
All patients seen at the primary care site are eligible to complete the online tool with their provider. Health providers and clinic staff will inform patients of the study through information sheets provided at the front desk of clinics or during an appointment. After reviewing the information sheet, the patient will note that they consent to proceed. To preserve anonymity, signed consent from patients will not be sought. The inclusion criteria for the 1-month follow-up with patients is as follows: used the tool approximately 1 month ago with their healthcare provider, able to provide consent, 18 years old or above, able to converse in English and able to be reached via telephone or email.
The primary aim of this pilot study is to assess the acceptability and feasibility of the intervention in a clinical setting and assess the short-term impact of the tool on patients. There is no predefined sample for patients completing the tool with their provider. This pilot study will help determine study sample calculations for future clinical trials and the usage and length of time to complete the tool will be monitored.37 Of those patients who complete the tool and survey, a subset will be contacted for follow-up. The target sample size for 1-month follow-up is 200 patients in each province for a total of 400 patients. We anticipate that this sample size will be robust enough to determine the acceptability of using the tool, as well as provide data on impact that will allow for sample size calculation for future studies of the impact of such tools on income itself.
Quantitative data collection
Online tool output
We will collect a set of data points on each use of the tool. We will not be able to distinguish repeat users. The tool will record answers to the following demographic questions: age, immigration status, employment status, whether someone in the household has a disability, household income and how many people live in the household and any existing benefits or tax credits received by the patient. The tool will also track clinic site, start time and end time of use, benefits recommended (output of tool) and proportion of users who complete the tool.
At the end of the tool, patients will be asked to complete a brief survey on their experience of using the tool and to provide contact information if interested in being contacted in the future. This survey will capture whether patients found the tool helpful, whether they would recommend the tool to a friend or family member and whether they understood the information provided to them. Lastly, the survey will use a Likert scale for patients to mark their confidence in taking next steps based on the information provided to them following their initial use of the tool with providers. Since there are no standardised instruments for evaluating this type of intervention the research team developed surveys to learn about patient perceptions of the tool after immediate use. At the end of the tool, we will ask patients’ permission to have a research coordinator follow-up with them via telephone or email to conduct a structured interview 1 month after their use of the tool in the clinic. This subset will be a convenience sample of all patients who provide their contact information and consent to an interview.
Qualitative data collection
Provider focus groups and survey
Three months after participating in the online income tool pilots, providers will be asked to complete an online, anonymous survey about their experience of using the tool. The purpose of this survey is to understand the providers’ perspective on whether they would use the tool in the future and whether they would recommend it to a colleague. Surveys will also capture how many times providers used the tool, whether providers felt they had enough time to do the tool with their patients, as well as the biggest benefit and drawback of using the tool, respectively. Providers at each site will also participate in a focus group discussion that explores the use of the tool over the last 3 months and the barriers and facilitators to implementation. Focus groups will provide a setting for in-depth discussion around the tool’s integration into regular clinical workflow, suggestions for its improvement, provider attitudes about addressing poverty in primary care, as well as factors that inhibited use of the tool during piloting at each site. A set of questions will be used to guide the focus groups and the discussions will be audiorecorded and transcribed verbatim.
Provider observations and feedback
During the 3-month period of pilot testing the online income tool at three sites in Winnipeg and Toronto, respectively, the use of the tool and its accompanying feedback from study team members and participating staff is being collected on an ongoing basis. Analytics regarding the number of times the tool is being used at each site are recorded and shared with study team members on a weekly basis and any feedback shared about the tool in informal conversations during site visits, through email or interim reports is noted in a feedback matrix that will be used when developing the tool in preparation for its next phase of use.
The primary outcome of this study is patient and provider perceptions around the integration of a tool addressing income in primary care settings (assessed through patient surveys, telephone interviews with patients at 4 weeks, provider focus groups and provider surveys). Additional outcomes that will be measured include patient access to financial benefits 4 weeks after their use of the tool (assessed through telephone interview at 4 weeks) (table 2). Descriptive statistics will be calculated (counts, percentages, means) to summarise variables including patient characteristics, usage of the tool and patient outcomes for all six sites. Outcome measures will be dichotomous and a bivariate analysis (using Student t-tests and χ2 tests, as appropriate) will be performed to determine associations between patient characteristics recorded from the tool and outcome measures (eg, whether programme was helpful, whether the patient is confident in taking next steps and whether their financial situation improved). Independent variables associated with positive patient outcomes and negative patient outcomes will be analysed separately. Logistic regression analysis will be performed to identify variables independently associated with patient outcome measures.
A secondary outcome that will be assessed in this study is the providers’ perspectives on the feasibility and acceptability of the tool using qualitative analysis. The field notes and transcripts of the focus groups with providers will be analysed thematically.38 An initial coding framework will be developed using the focus group guide. Two team members will independently read and code transcripts using Dedoose V.7.0.23 (SocioCultural Research Consultants, Los Angeles, California, USA). Themes will be refined in an iterative process by comparing codes with the research team and reaching consensus on a final coding framework. The thematic analysis will focus on identifying key facilitators and barriers to implementation and provider perspectives on the impact of the tool and ways to improve similar tools. Field notes collected throughout the study will help contextualise findings for each site and identify similarities and differences across sites. Open-ended questions from patient and provider surveys will also be thematically coded and categorised. We will identify common experiences associated with using the tool that may provide insight into how the tool works and ways to improve similar tools in the future.
We will organise an advisory committee made of up patients, community agencies and staff to provide ongoing feedback on the project. Our aim is to engage four to six patients to provide input on how to improve the online tool and its use in clinical settings. For this study, the advisory committee will play an important role in understanding how to improve the tool interface and what information will be most useful for patients to improve the tool output. The advisory committee will meet approximately once a month beginning in July 2016 until the end of data collection to help interpret findings, make recommendations to the online tool and suggestions for integrating its use within the care team. Ongoing engagement with patients and stakeholders will help to determine modifications to the tool, contextualise our findings and promote greater uptake in the future.39
Ethics and dissemination
This study has been approved by St Michael’s Hospital Research Ethics Board, the Health Research Ethics Board at the University of Manitoba and the Michael Garron Hospital Research Ethics Board. Informed consent will be obtained for all study participants. Data collected by the online tool will be anonymous, with no link between answers to questions in the tool and personal identifying data. Some patients may feel discomfort when asked the screening question and they may feel shame or fear stigma if they are experiencing income insecurity. We will attempt to lessen this possibility by encouraging health providers to normalise the experience for patients, for example, “I’m asking many of my patients this question over the next 3 months”. Patients may feel obligated to complete the tool with their healthcare providers. During training sessions, all providers will be asked to emphasise that this intervention is optional and not part of routine care. Patients will also be informed that they can stop using the tool at any time. Healthcare providers will also be trained to manage patient expectations by stating that this tool may or may not identify benefits which could provide increased income. All patient and provider surveys will be anonymised. Finally, participants in focus groups will not be identified by name and all transcripts will be anonymised during transcription.
This study uses an ‘upstream’ approach to address a root cause of poor health outcomes: poverty. By exploring the feasibility and acceptability of using an online tool we can establish a standardised process to screen patients for low income in routine primary care settings. We will also examine and report on local factors that influence implementation at the different clinic sites. Moreover, the implementation of the tool will be pragmatic, with the ultimate aim to bring such tools into broader practice through integration into primary healthcare settings. The findings from this study will provide insight into individual-level interventions to address the social determinants of health in primary care. Such tools may be useful to a diversity of primary care providers and could be applicable to other healthcare settings, such as in discharge planning at healthcare institutions. Important strengths of the intervention include opportunities for providers to offer feedback on the content, design and overall usability of the tool and the follow-up with patients about changes in their financial situation. Patients and community agencies represented in the advisory group will help ensure that this study remains focused on patient-centred outcomes and experiences and will contribute particular perspectives to the interpretation of our findings.
We will evaluate the implementation and short-term effects of this online income security tool within six health clinics. We will attempt to engage a broad representation of health providers at each site and will invite all staff to participate in our study. The information provided in the output of the tool may not be suitably tailored to the needs of all individuals. The time frame of this study does not permit us to examine health effects, which we would anticipate would take longer than 1 month to develop, and which would require a more intense intervention. Future research could examine whether using this tool, in coordination with other services, with patients identified as being at risk of developing complex health and social needs could impact on health and health service use.2 40 The hypothesis tested would be that that addressing income security may reduce the risk of poor health and high service use for some patients.
There are several limitations to the proposed the study. First, the study uses a convenience sampling method so participants who declined to use tool or could not be reached at follow-up were not captured. Second, the sites chosen to pilot the tool were already interested in addressing income security at their clinics. Furthermore, all site materials were in English so findings may not be generalisable to other clinical settings. Lastly, while we anticipate that the tool will be able to identify benefits that a patient could be eligible for, the complex process of applying for benefits may be a barrier to improving income security and a 1-month follow-up may be too short of a time frame within which to assess impact. However, this is one of the few studies on SDOH interventions that follows up with patients and a major strength is implementing the tool across multiple sites in two provinces.
This study is timely as awareness and a commitment to act on the SDOH is growing within the health sector in Canada6 22 41 42 and globally.43–45 Continuing medical education events on poverty and health have been established and new medical school curricula is being created.46 These efforts may begin to change medical practice. Yet, there are few studies that have evaluated the implementation and impact of such initiatives. The findings of this study will contribute to the design of SDOH interventions in healthcare, particularly when considering the role of technology and the practical challenges of incorporating interventions into busy health organisations.
