Screening for the social determinants of health in clinical practice is still widely debated.
A scoping review was used to (1) explore the various screening tools that are available to identify social risk, (2) examine the impact that screening for social determinants has on health and social outcomes, and (3) identify factors that promote the uptake of screening in routine clinical care.
Over the last two decades, a growing number of screening tools have been developed to help frontline health workers ask about the social determinants of health in clinical care. In addition to clinical practice guidelines that recommend screening for specific areas of social risk (e.g., violence in pregnancy), there is also a growing body of evidence exploring the use of screening or case finding for identifying multiple domains of social risk (e.g., poverty, food insecurity, violence, unemployment, and housing problems).
There is increasing traction within the medical field for improving social history taking and integrating more formal screening for social determinants of health within clinical practice. There is also a growing number of high-quality evidence-based reviews that identify interventions that are effective in promoting health equity at the individual patient level, and at broader community and structural levels.
- Social determinants
- Marginalized patients
- Intersectoral action
- Community oriented primary care
- Secondary prevention
Determining whether the social determinants influence health is no longer a topic of debate, at least not within the health field. Landmark documents such as the 2008 Closing the Gap report by the World Health Organization Commission on Social Determinants of Health  and books such as The Spirit Level by Wilkinson and Pickett  have provided substantial evidence to adequately demonstrate that decreasing income, education, social status, and social support is correlated with increased morbidity and premature mortality (also known as the social gradient). Despite the widespread acceptance of the role of social determinants in determining health, whether or not to screen for social determinants of health in clinical care remains a topic of considerable contention.
The two main groups who are less convinced about the value of screening for social determinants of health within clinical care adopt this stance for very different reasons. On the one hand, it has been shown that while many health workers can appreciate the connection between social factors and poor health, common themes explaining their reticence to ask about and address social determinants include being overworked, not knowing how to ask about social determinants or what to do about it once they find out, questioning whether addressing social determinants is part of their role, lacking role models and support in helping patients address the social determinants, being fearful of opening a “Pandora’s box” by embarking on this path, and feeling helpless or powerless in the face of such daunting social challenges . A survey conducted by the Robert Wood Johnson Foundation found that four out of five physicians do not feel confident in their capacity to meet their patients’ social needs, and they believe this impedes their ability to provide quality care .
On the other hand, there are also champions in the field of social determinants who question whether screening is the most appropriate level of intervention. These experts in the field rightly point out that making an impact on social determinants requires broad intersectoral action and whole of government approaches . The factors influencing people’s daily living conditions are generally political and structural . These experts therefore question what value, if any, talking to patients about these issues could possibly do to change the larger political and structural forces at play within a society. They consider that action on the social determinants must occur beyond the health sector, but perhaps do not sufficiently appreciate the potential catalyzing role of frontline health workers in advocating and partnering for broader social change, whether at the grassroots community level or at the broader societal level nationally and globally . Indeed, there are many examples of the important influence of physician advocates in many spheres that affect health, from raising awareness on climate change to the 2017 Nobel Peace Prize being awarded to an initiative launched by International Physicians for the Prevention of Nuclear War.
There is growing interest among frontline health workers, particularly, but not limited to, those working in areas such as immigrant and refugee health, caring for homeless and marginally housed persons, inner city health, Indigenous health, social pediatrics, cultural psychiatry, community-oriented primary care and global health, who want to be equipped with evidence-based guidance on how to better care for and support marginalized populations as part of their day-to-day clinical practice. Indeed, with the Lancet Commission on the Education of Health Professionals for the 21st Century highlighting the need for increasing emphasis on social accountability in medical education , as well as expanding networks of equity-focused medical educators such as Towards Unity for Health (TUFH), there is a strong core group of health professionals wanting to be more proactive when it comes to addressing social determinants in clinical care.
The purpose of this review is therefore to examine the evidence relating to screening for the social determinants of health in clinical care, including identifying (1) what screening tools currently exist, (2) the potential impact screening can have on improving patient outcomes (i.e., effectiveness), and (3) what factors promote health worker uptake and offer of screening in clinical settings (i.e., adherence).

However, as this is an emerging field of research, discussions with key informants and key word searches in Google Scholar were used to identify the grey literature. As well, reference lists of the articles relating to multi-dimensional social risk screening, where there is a dearth of research studies, were scanned to identify other relevant articles using a snowball technique. In this way, a further 41 publications were identified, and data extraction and synthesis was also carried out as detailed above.
Finally, adolopment was used to incorporate evidence that has already been synthesized from previous systematic reviews and meta-analyses. Four evidence-based databases were scanned for high-quality reviews relating to screening for social determinants in clinical care, or related interventions to improve health equity, where the recommendations are to “recommend” or “strongly recommend” the intervention based on moderate- or high-quality evidence. The databases searched include The Canadian Task Force on Preventive Health Care, the US Preventive Services Task Force, the NICE UK database, and the Guide to Community Preventive Services. In total, 27 evidence-based reviews were identified, and these interventions are summarized in a separate table.

Whether to screen
The findings of the review are summarized below according to the following main themes: (1) screening tools to identify social determinants in clinical care, (2) evidence of screening effectiveness for improving health and social outcomes, (3) adherence of health professionals to screening guidelines, and (4) whether or not to screen for social determinants of health and under what circumstances (i.e., balancing the benefits versus potential harms).
Screening tools to identify social determinants
Sample psychosocial screening tool for prenatal care
Do you have any problems that prevent you from keeping your health care appointments?
How many times have you moved in the past 12 months?
Do you feel unsafe where you live?
Do you or any members of your household go to bed hungry?
In the past two months, have you used any form of tobacco? In the past two months, have you used drugs or alcohol (beer, wine or mixed drinks)?
In the past year, has anyone hit you or tried to hurt you?
How do you rate your current stress level—low or high?
If you could change the timing of this pregnancy, would you want it to happen earlier, later, not at all or would you not change it?
Over the last two decades, a growing number of screening tools have been developed to help frontline health workers ask about social determinants of health in clinical care, ranging from identifying food insecurity in specific populations, such as in the elderly  or among diabetic patients , to screening for violence including adverse childhood experiences , intimate partner violence [15, 16], and elder abuse . For instance, Gallione and colleagues conducted a systematic review of screening tools for elder abuse and identified 11 such tools, some of which had been tested and validated . The authors conclude that the choice of which screening tool to choose depends upon the appropriateness to the clinical setting and context.
In terms of screening for violence, which is generally more developed than other social determinants of health content domains, there are publications on screening as it relates to a variety of settings, from the emergency department  to the operating room . As well, there are screening tools not only to identify victims of violence, but also potential perpetrators [21, 22]. However, in terms of screening for social determinants of health more broadly, there are often fewer tools that cover multiple domains in a more comprehensive way. For instance, the Poverty Tool, as the name suggests, focuses primarily on screening for financial insecurity using the simple phrase “do you have trouble making ends meet at the end of the month” . This tool is currently in the process of being evaluated in primary care .
In the field of pediatrics, Morone from the University of Pennsylvania conducted a recent review of screening tools to identify the social determinants of health in pediatric care; however, relatively few were identified, and among these, the majority focused on a limited number of domains and used heterogeneous approaches for identifying patients at increased risk . Similarly, Pai and colleagues from Ontario, Canada, also conducted a review to identify social risk screening tools for pediatric inpatients, and among 44 instruments identified, 61% focused on a single social risk theme, only 18% covered more than 5 themes, and none met the criteria for a valid content and methodologically strong social risk screening instrument for hospitalized children . The authors conclude that more research is needed in this area.

5. Health-related behaviors
• Sense of healthy or unhealthy behaviors
• Facilitators of health promotion (e.g., behaviors among peers)
• Triggers for harmful behaviors and motivation to change (determined through motivational interviewing)
• Diet and exercise habits
• Facilitators or barriers to medication adherence
• Tobacco, alcohol, drug use habits
• Safety precautions: seatbelts, helmets, firearms, street violence
6. Access to and utilization of health care

• Health literacy and numeracy
• Barriers to making appointments (e.g., child care, work allowance, affordability of copayment, transportation)
For specific population subgroups, such as adolescents, the HEADSS psychosocial screening tool has been used for several decades and examines (1) the home environment, (2) education and employment, (3) activities, (4) drugs, (5) sexuality, and (6) suicide and depression . Similarly, the Family First screening tool has been used in school-based medical clinics to assess (1) maternal age; (2) education, income, and employment; (3) mental health problems and addictions; (4) parental attachment; (5) marital discord; and (6) social isolation . Thus, a wide range of screening tools are already in existence, though mostly in terms of assessing a single domain of social risk, with some promising examples of multi-domain tools or approaches to social history taking.
Evidence of screening effectiveness on improving patient outcomes
The evidence of effectiveness of screening for social risk can be divided into two categories: (1) screening for single domains of social risk versus (2) simultaneously screening for multiple domains of social risk. In terms of the former, there is a much larger literature available, as well as several clinical practice guidelines, relating to screening for specific single domains of social risk (e.g., screening for intimate partner violence). However, it is known that social risks tend to cluster. Therefore, intuitively, it makes sense to simultaneously screen for multiple domains of social risk. This is an approach that has long been used by physicians in the field of social medicine, but a relatively recent focus of research inquiry with regards to mainstream care.
The impact of screening for a single domain of social risk
There are many evaluations of screening for single domains of social risk and, in particular, a large literature on screening for different types of violence, particularly intimate partner violence , as well as suicide (self harm), child abuse, and elder abuse .
While a Cochrane Review did not find sufficient evidence to support an association between screening and reduced harm to women experiencing violence , this does not mean that screening is not effective, simply that there is not sufficient evidence at this time to demonstrate an effect . Similarly, an analysis from the UK found that the HITS (Hurts, Insults, Threatens and Screams) scale is a sensitive screening tool able to identify victims of violence in health care settings, most women consider screening for domestic violence to be acceptable, and there is growing evidence of effectiveness for advocacy and psychosocial counselling, nonetheless, universal screening of all women presenting to clinical care in the absence of violence-related concerns or health conditions does not yet meet the criteria of the National Screening Committee of the NHS .
Not surprisingly, the rates of screening for violence in practice across various health care settings (i.e. prenatal care and pediatrics) are variable . Many in the field advocate for developing more evidence-based approaches to assist women when they do disclose abuse and for greater emphasis on training health professionals to respond appropriately to such disclosures . This is important recognizing that addressing such issues in clinical care can be complex and often raises certain ethical challenges  and requires a broader systems approach to ensure patient-centered care, access to appropriate referral pathways, and timely follow-up . Implementation science research is also needed to improve screening uptake and ensure the translation of research findings into routine practice .
In terms of current national guidelines, the US Preventive Services Task Force (USPSTF) recommends that health workers screen all women of childbearing age for intimate partner violence and provide or refer women who screen positive to intervention services (Grade B) . The Canadian Task Force on Preventive Health Care (CTFPHC) considers that while there is insufficient evidence to recommend for or against routine universal screening for violence against either pregnant or nonpregnant women (grade I), “clinicians should be alert to signs and symptoms of potential abuse and may wish to ask about exposure to abuse during diagnostic evaluation of these patients” . There is fair evidence to refer women who have spent at least 1 night in a shelter to a structured program of advocacy services . The Community Preventive Services Task Force (CPSTF) as well as the USPSTF and CTFPHC all recommend the use of early childhood home visitation programs based on strong evidence of their effectiveness in reducing child abuse and neglect among high-risk families [43, 44].
In terms of youth violence, a recent systematic review found evidence that health care-based violence intervention programs reduced recidivism as well as health care and criminal justice system costs . In addition, intermediate outcomes included increased service use, positive attitude change, and decreases in violence-related behavior. Regarding suicide, promising interventions likely to be effective in reducing suicidal behaviors are medical practitioner and gatekeeper education, and restriction of access to lethal means of suicide .
The impact of simultaneous screening for multiple domains of social risk
There is a small but growing body of evidence on the impact of screening for social determinants of health more broadly in clinical care. Early research has shown that health workers who feel at ease asking about social determinants of health in clinical care are more likely to report having helped their patients in addressing these issues .
The Task Force on Community Preventive Services has conducted systematic reviews of early childhood development interventions and family housing interventions and concluded that these interventions do effectively address sociocultural factors that influence health . The Task Force strongly recommends publicly funded, center-based, comprehensive early childhood development programs for low-income children aged 3–5 years which are effective in preventing developmental delay. The Task Force also recommends housing subsidy programs for low-income families involving rental vouchers for use in the private housing market. This has been shown to improve neighborhood safety and reduce family exposure to violence.
Since this is an emerging area of research, there are mostly primary studies available including non-RCT design , as well as a smaller number of RCTs but focusing on diverse types of screening, with a range of different interventions and populations involved, from using patient navigators in primary care , to screening and referral for social risk at routine well child visits . There are also a number of clinical practice guides to promote awareness among frontline clinicians, and either encourage screening  or at least incorporate a social determinants approach in clinical care and be aware of opportunities when it would be appropriate and good clinical practice to do so.
Adherence of health professionals to screening guidelines
Even once there are clear national screening guidelines, implementation remains a challenge in this area which can reduce effectiveness in practice. In the Netherlands, while most clinicians were aware of guidelines to identify and address child abuse, fewer than half routinely used the guideline in clinical care, largely because they were not in the habit of doing so . Factors that prevented clinicians from using the guidelines included being unaware of the content, lacking self-efficacy or confidence in being able to apply the guidelines properly, and not having pre-established linkages with referral resources . Four program components that help to increase clinician self-efficacy for screening include institutional support, clear screening protocols, initial and ongoing trainings, and facilitation of access to onsite and/or offsite referral and support services . Adaptation of screening protocols to different clinical settings is also important to assist clinicians in seeing the relevance of screening .
Another approach to promote adherence to clinical screening guidelines is to provide incentives and to make referral services more widely available. The US Affordable Care Act includes screening and brief counseling for intimate partner violence as part of required free preventive services for women . There is also evidence that more time to address complex issues, even simply adding a few minutes onto the consultation, is helpful , and in primary health care, there is continuity of care and ongoing opportunities to address these issues over time as well as sharing the responsibility for care with a broader clinical team as well as partners working in the community in local NGOs and referral support centers.
Whether or not to screen for social determinants of health
Already a decade ago, Silverstein and colleagues from Boston University had conducted a review on screening for social determinants of health in pediatric primary care, including identifying factors such as maternal depression, domestic and intimate partner violence, school readiness and eligibility for early learning programs, food insecurity, and housing quality and affordability . The authors concluded that each of these factors is closely linked to patient health outcomes and that the growing body of evidence supports social screening and intervention in primary care, while recognizing the need to continue to develop and refine available screening tools and interventions.
More recently, Garg and colleagues warned about avoiding the unintended consequences of screening for social determinants, particularly in the absence of available referral networks to address identified social needs . This sparked a great deal of debate from supporters of screening who argued that even in the absence of available programs and services, screening can help to identify patients who need more support in primary care  and can lay the groundwork for the future development of interventions that are better adapted to patient needs .
This review has demonstrated that over the last few decades, there has been a growing literature on screening for the social determinants of health in clinical practice. There are an increasing number of screening tools for single and multiple dimensions of social risk and also for specific populations ranging from veterans  to the LGBT community . There are also more and more primary research studies and reviews being published that examine the efficacy and effectiveness of screening. For instance, Naz and colleagues  found that health workers who have sensitive and caring ways to ask about social determinants were able to open the door to addressing these issues in clinical care. A cluster RCT conducted by Garg and colleagues  demonstrated that screening for social determinants of health during well child care visits led to greater referral to social support resources, greater odds of being employed and having child care at 12 months of follow-up, and lower odds of being in a shelter. In addition to improving social outcomes, studies have also shown improvements in health outcomes, such as Strong and colleagues  who found that screening for social determinants, and particularly for violence exposure, among youth presenting with injuries led to a reduction in recurrent presentations to clinical care for repeat injuries (i.e., recidivism).
Yet, amassing a body of evidence to demonstrate sufficient benefit in a complex area such as this has resulted in some divergence in national screening recommendations even around single-dimension screening such as screening for intimate partner violence. National recommendations around multi-dimension screening for social risk are not yet available since the evidence base to support such recommendations is highly under-developed at present. More research is still needed in this area to be able to demonstrate whether screening for social risk, and especially for multiple domains of social risk, which require complex and individually tailored interventions, often developed through participatory and community-informed approaches to address local contextual factors  and which lead to multiple relevant outcome measures, will succeed in meeting the Wilson and Jungner screening criteria . There is also an ongoing debate regarding the potential unintended consequences of screening which very much depends on how this is done and how well-trained and prepared the clinical staff are and whether referral resources have been sufficiently mapped out. Thus, while adherence to screening in the area of well-defined clinical practice guidelines already demonstrates certain challenges, as one moves towards more complex areas such as screening for social determinants of health, a far more robust evidence base will be needed to generate widespread support and health care culture change in this area.
In light of the current state of the evidence on screening for the social determinants of health, it is important for frontline clinicians to be aware that even when there is insufficient evidence to recommend universal screening of the general population of asymptomatic individuals using specific screening tools and predetermined interventions, clinicians nonetheless require training to know how to ask about social determinants and how to map out referral resources and implement other models of care (e.g., patient navigators) when social risk is relevant to the clinical presentation. Reasons to do so are multiple including (1) providing whole-person care rather than focusing only on the disease, (2) reducing missed opportunities for diagnosis by having all the important information in terms of living conditions and social context, (3) reducing “revolving door medicine” and recurrent emergency room visits by understanding and addressing the underlying causes of the presenting health issues, (4) providing more cost-effective care by intervening early and preventing hospitalization, (5) increasing adherence to medication and improving health by prescribing medicines that patients can afford and are therefore more likely to take regularly as prescribed, and (6) providing more trauma-informed and structurally competent care.
For instance, unless health workers routinely ask about exposure to violence in the work up of pelvic pain, they may be missing important opportunities for intervention and may instead embark upon a potentially iatrogenic diagnostic odyssey that misses the main factors underlying the clinical presentation . Similarly, unless clinicians ask their patients whether they will be able to afford the medicines being prescribed, this can lead to medication non-compliance and worsening of the health condition . Just because there may be insufficient evidence to recommend universal screening does not mean that social determinants is unimportant or should be left out of clinical care. Rather, having a heightened awareness of social determinants and enquiring about social history is part of good clinical practice that can lead to better adapted diagnosis and management in a wide range of areas.
Indeed, some would even go so far as to say there is an ethical imperative to act on the social determinants of health in clinical care. According to Rapp-Paglicci and Dulmus, medical centers in the US see 1.4 million serious violent crime victims every year; however very few medical centers evaluate patients beyond physical conditions, and even fewer complete toxicology or psychosocial screens to evaluate for substance abuse and psychological conditions as a result of trauma . Victims of violence are often given medical assistance and discharged without recognition of the serious after effects of trauma for both themselves and their families, as well as the high likelihood of re-victimization..

It is also important to note that screening for social risk is a form of secondary prevention. However, there exists a continuum of strategies to improve the health of populations and reduce inequities , from diagnosis and treatment, to the three levels of prevention, to health promotion (i.e., healthy public policies and creating supportive environments for health) , as well as broader intersectoral and whole of government action on the social determinants of health . Beyond what can be done at the doctor-patient level, health workers can be important advocates and catalysts of broader changes to create more supportive environments for health and to change social norms, systems, and structures, to prevent these issues from occurring in the first place. This includes informing local and national policy-makers of effective interventions that do exist and ensuring that these are made available for the local population.
There is a growing body of evidence in support of screening for various aspects of social risk within routine clinical care, as part of a wider continuum of strategies for improving population health and reducing health inequities. At various times in a person’s life, everyone may face challenges in one, or often multiple, domains of social risk. Screening for social determinants of health can help to identify patients who may benefit from greater support in one or more areas, thus promoting whole-person care for the entire population, and particularly for those who are marginalized and underserved.
While there is not always consistency in clinical practice guidelines for single-dimension social risk screening (e.g., for identifying intimate partner violence) due to variability of interventions studied and outcomes measured, and while a great deal more research is needed in the area of multi-dimension screening, which is most relevant to the clinical context and meeting patient needs, there already exist many effective and evidence-based interventions to promote health equity, but clinicians would need to identify patients for whom referral to these interventions would be appropriate and may also need to raise awareness and convince local policy-makers to make these interventions available in the local setting. Thus, screening for social determinants of health is an emerging area of clinical practice that still requires a great deal more research and ongoing continuing medical education on how to do this in practice.
Yet, there is increasing traction within the medical field for improving social history-taking and integrating more formal screening for social determinants of health within clinical practice. There is an increasing diversity of screening tools now available, which can be adapted and tailored to the local context, practice population, and needs. There is therefore a great deal that frontline health workers can already do to begin to address social determinants in clinical practice and beyond.
