Theorising the social within physician decision making

Can peer effects explain prescribing appropriateness? a social network analysis

BACKGROUND

Optimizing prescribing practices is important due to the substantial clinical and financial costs of polypharmacy and an increasingly aging population. Prior research shows the importance of social relationships in driving prescribing behaviour. Using social network analysis, we examine the relationship between a physician practices' connectedness to peers and their prescribing performance in two German regions.

METHODS

We first mapped physician practice networks using links established between two practices that share 8 or more patients; we calculated network-level (density, average path length) and node-level measures (degree, betweenness, eigenvector). We defined prescribing performance as the total number of inappropriate medications prescribed or appropriate medications not prescribed (PIMs) to senior patients (over the age of 65) during the calendar year 2016. We used FORTA (Fit fOR The Aged) algorithm to classify medication appropriateness. Negative binomial regression models estimate the association between node-level measures and prescribing performance of physician practices controlling for patient comorbidity, provider specialization, percentage of seniors in practice, and region. We conducted two sensitivity analyses to test the robustness of our findings - i) limiting the network mapping to patients younger than 65; ii) limiting the network ties to practices that share more than 25 patients.

RESULTS

We mapped two patient-sharing networks including 436 and 270 physician practices involving 28,508 and 20,935 patients and consisting of 217,126 and 154,274 claims in the two regions respectively. Regression analyses showed a practice's network connectedness as represented by degree, betweenness, and eigenvector centrality, is significantly negatively associated with prescribing performance (degree-bottom vs. top quartile aRR = 0.04, 95%CI: 0.035,0.045; betweenness-bottom vs. top quartile aRR = 0.063 95%CI: 0.052,0.077; eigenvector-bottom vs. top quartile aRR = 0.039, 95%CI: 0.034,0.044).

CONCLUSIONS

Our study provides evidence that physician practice prescribing performance is associated with their peer connections and position within their network. We conclude that practices occupying strategic positions at the edge of networks with advantageous access to novel information are associated with better prescribing outcomes, whereas highly connected practices embedded in insulated information environments are associated with poor prescribing performance.

Review of social networks of professionals in healthcare settings-where are we and what else is needed?

Background

Social Network Analysis (SNA) demonstrates great potential in exploring health professional relationships and improving care delivery, but there is no comprehensive overview of its utilization in healthcare settings. This review aims to provide an overview of the current state of knowledge regarding the use of SNA in understanding health professional relationships in different countries.

Methods

We conducted an umbrella review by searching eight academic databases and grey literature up to April 30, 2021, enhanced by citation searches. We completed study selection, data extraction and quality assessment using predetermined criteria. The information abstracted from the reviews was synthesized quantitatively, qualitatively and narratively.

Results

Thirteen reviews were included in this review, yielding 330 empirical studies. The degree of overlaps of empirical studies across included reviews was low (4.3 %), indicating a high diversity of included reviews and the necessity of this umbrella review. Evidence from low- and middle-income countries (LMIC), particularly Asian countries, was limited. The earliest review was published in 2010 and the latest in 2019. Six reviews focused on the construction or description of professional networks and seven reviews reported factors or influences of professional networks. We synthesized existing literature on social networks of health care professionals in the light of (i) theoretical frameworks, (ii) study design and data collection, (iii) network nodes, measures and analysis, and (iv) factors of professional networks and related outcomes. From the perspective of methodology, evidence lies mainly in cross-sectional study design and electronic data, especially administrative data showing “patient-sharing” relationships, which has become the dominant data collection method. The results about the impact of health professional networks on health-related consequences were often contradicting and not truly comparable.

Conclusions

Methodological limitations, inconsistent findings, and lack of evidence from LMIC imply an urgent need for further investigations. The potential for broader utilization of SNA among providers remains largely untapped and the findings of this review may contain important value for building optimal healthcare delivery networks.

How the study of networks informs knowledge translation and implementation: a scoping review

Background

To date, implementation science has focused largely on identifying the individual and organizational barriers, processes, and outcomes of knowledge translation (KT) (including implementation efforts). Social network analysis (SNA) has the potential to augment our understanding of KT success by applying a network lens that examines the influence of relationships and social structures on research use and intervention acceptability by health professionals. The purpose of this review was to comprehensively map the ways in which SNA methodologies have been applied to the study of KT with respect to health professional networks.

Methods

Systematic scoping review methodology involved searching five academic databases for primary research on KT that employed quantitative SNA methods, and inclusion screening using predetermined criteria. Data extraction included information on study aim, population, variables, network properties, theory use, and data collection methods. Descriptive statistics and chronology charting preceded theoretical analysis of findings.

Results

Twenty-seven retained articles describing 19 cross-sectional and 2 longitudinal studies reported on 28 structural properties, with degree centrality, tie characteristics (e.g., homophily, reciprocity), and whole network density being most frequent. Eleven studies examined physician-only networks, 9 focused on interprofessional networks, and 1 reported on a nurse practitioner network. Diffusion of innovation, social contagion, and social influence theories were most commonly applied.

Conclusions

Emerging interest in SNA for KT- and implementation-related research is evident. The included articles focused on individual level evidence-based decision-making: we recommend also applying SNA to meso- or macro-level KT activities. SNA research that expands the range of professions under study, examines network dynamics over time, extends the depth of analysis of the role of network structure on KT processes and outcomes, and employs mixed methods to triangulate findings, is needed to advance the field. SNA is a valuable approach for evaluating key network characteristics, structures and positions of relevance to KT, implementation, and evidence informed practice. Examining how network structure influences connections and the implications of those holding prominent network positions can provide insights to improve network-based KT processes.

Professionalisation of International Medical Volunteer Work to Maintain Ethical Standards: A Qualitative Study Exploring the Experience of Volunteer Doctors in Relation to UK Policy

Doctors from the United Kingdom are increasingly involved in international medical volunteerism in low- and middle-income countries (LMICs). Although supported by government policy this practice lacks infrastructure and coordination. Volunteer activities can have positive impact but also risk causing harm. Without external governance the responsibility lies with volunteers and their organisations to self-evaluate their activities. This study aimed to explore influences affecting volunteer engagement with ethical standards and evaluative practice. Semi-structured interviews were conducted with seven doctors working in the Scottish National Health Service with volunteer experience in LMICs. Findings were analysed thematically to explore this issue in view of ongoing policy development. Although ethical standards were valued by participants they were unaware of relevant government policy. Influences on volunteer development are unstructured and vary in quality. Evaluation lacks structure and framing. Volunteer physicians face a number of barriers to engaging in critical evaluation of their activities in LMICs. Development and professionalization of medical volunteering in LMICs needs to address volunteer preparation and evaluative practice to maximise the benefits of volunteering, reduce the risk of harm and maximise learning and accountability. Further areas of research are suggested to inform professionalisation of this sector.

The Middle East and Africa Code of Promotional Practices in the Pharmaceutical Industry

The pharmaceutical industry is known for investing heavily in promotions targeted at healthcare professionals (HCPs). Governments around the world try to regulate unwanted promotional practices in different ways. Where binding laws are in place in the U.S.A., European governments favor self-regulation. The purpose of this research is the evaluation of the Middle East and Africa Code of Promotional Practices (MEACPP) as a preliminary draft and its implications. Our paper fills a research gap by looking into the perceptions of the parties involved, analyzing their interests, and predicting possible outcomes. We used a mixed-method approach. Interviews were conducted with pharmaceutical companies and associations; while a questionnaire was administered to HCPs. Our findings suggest that all parties are in favor of more transparency. However, when it comes to disclosing the received financial support, the HCPs are hesitant. An estimated 20% would be willing to fully disclose their received benefits, which is in line with their European colleagues. Multinational pharmaceutical companies follow their own in-house standards and fear being at a competitive disadvantage when local companies can promote their drugs without any strings attached. MEA pharmaceutical companies do not see the potential benefits of analyzing the publicly available data to identify key opinion leaders (KOLs). The limitation of our research is the fact that the MEACPP has not been implemented yet and survey results are therefore based on expectations rather than real events.

Social Networks and Inter-professional Knowledge Transfer: The Case of Healthcare Professionals

This study examines the relationship between the structure of professional networks and patterns of inter-professional knowledge transfer in the healthcare setting. Collecting survey data and qualitative evidence from 118 professionals in a hospital department, we used theory on the sociology of professions and social networks to investigate patterns of knowledge transfer between doctors and nurses. First we found that members of different professions tend to be embedded in distinctive professional cliques, which in turn inhibit effective inter-professional knowledge transfer. Network structure, however, combines with individual characteristics in predicting knowledge transfer patterns. By occupying central positions in closely knit networks, clinical directors can facilitate knowledge transfer patterns between doctors and nurses. And actors who are legitimated both intra-professionally and inter-professionally to occupy brokerage positions in social networks, namely junior doctors and nurse managers, are more likely to gain access to non-redundant, valuable knowledge. The overall picture is one of network structure interplaying with the characteristics of individual actors in shaping the dynamics of professional interactions.

Ethical Integrity in Health Care Organizations: Currents in Contemporary Bioethics

The rise of managed care initiated a steady decline in solo and small group physician practices and the emergence of new delivery models built around large health care organizations (HCOs). Health care reform has only accelerated this trend as public and private payors shift to new payment methodologies that reward clinical and financial integration among providers. As a result, patients increasingly receive care from physicians and other health professionals organized into collaborative partnerships with one another and institutional providers, such as hospitals. As described below, this new organizational dynamic profoundly influences the clinical judgment of physicians. No longer can society simply depend on the professionalism of individual physicians to ensure ethical integrity in the health care setting. Rather, ethical integrity in the health care setting also requires a strong foundation of organizational ethics.

The influence of a professional physician network on clinical decision making

OBJECTIVE

The aim of this study was to examine the role of physicians' professional networks in decision-making processes.

METHODS

A professional network was examined in three stages: content analysis and categorization of discussions concerning decision-making processes, in-depth interviews, and a questionnaire.

RESULTS

The RAMBAM network has professional as well as social roles. On a professional level, physicians seek approval of their initial line of reasoning regarding their clinical cases, but will consider other approaches if such are suggested by persons of professional repute or if answers are based on evidence-based medicine and include referral to a relevant source. On a social level, physicians want to be part of their professional community and share information and experiences.

CONCLUSION

Physicians' professional networks have a social role that is expressed by a feeling of belonging to a community, as well as a professional role of capturing and disseminating medical knowledge during physicians' decision-making processes. Professional networks constitute a unique source of tacit knowledge that extends existing formal knowledge resources.

PRACTICE IMPLICATIONS

The study can increase physicians' awareness of professional networks as a unique source of tacit knowledge and can assist in the future design of medical professional networks as knowledge resources for medical decision making.

Social network analysis in primary care: the impact of interactions on prescribing behaviour

OBJECTIVES

In many healthcare systems of affluent countries, general practitioners (GPs) are encouraged to work in collaborative arrangements to increase patients' accessibility and the quality of care. There are two lines of thought regarding the ways in which belonging to a network can affect GP behaviour: (1) the social capital framework posits that, through relationships, individuals acquire resources, such as information, that allow them to perform better; and (2) the social influence framework sees relationships as avenues through which individual actors influence other individuals and through which behavioural norms are developed and enforced. The objective of this study is to provide an evaluation of the effects of GP network organisation on their prescribing behaviour.

METHODS

We used administrative data from a Local Health Authority (LHA) in Italy concerning GPs organisation and prescriptions.

RESULTS

We found that GPs working in a collaborative arrangement have a similar prescribing behaviour while we did not find a significant relationship between the centrality of a GP and her capability to meet LHA's targets.

CONCLUSIONS

Our data support the conclusion that, in the case of GP collaboration initiatives, the social influence mechanism is more relevant than the social capital mechanism.

Figuring it out in the moment: a theory of unregulated care providers' knowledge utilization in dementia care settings

BACKGROUND

Within the context of knowledge translation, the disconnect between the results of research and the practice patterns of nursing care providers has not been reported in the context of institutional dementia care practice. Therefore, little is known about how knowledge about best dementia care practice, defined broadly as the person-centered approach, gets used by institutional nursing care providers.

AIM

Unregulated care providers provide the majority of nursing care for older people with Alzheimer's disease and related disorders living in long-term care facilities. The purpose of this grounded theory study was to explore the process whereby these workers use knowledge about person-centered care in their dementia care practice.

METHODS

Transcribed data from tape-recorded interviews with 20 unregulated care providers among eight long-term care facilities in Ontario, Canada, were coded and categorized at progressively more abstract levels until concepts and the relationships among them were integrated in a middle-range theory of knowledge utilization.

RESULTS

The theory of Figuring it Out in the Moment illustrates how unregulated care providers in dementia care settings practice in the context of unpredictability, variability, and personal threat. Their use of knowledge about person-centered care is dependent on the existence of certain individual and relational conditions that interrelate with four separate, but interconnected, phases of clinical decision-making and action.

CONCLUSIONS

As a middle-range theory, Figuring it Out in the Moment is concrete and pragmatic information for promoting evidence-based dementia care not included in existing overarching knowledge utilization frameworks. Areas for further investigation include how knowledge utilization is conceptualized, as well as the influences of practitioners' clinical decision-making, the nature of caregiving with particular client populations, and the characteristics of individuals alone and in relationship on the utilization of best practice knowledge.

Redefining accountability in health care: managing the plurality of medical interests

Conflict in health service delivery is common. It is often attributed to disputes between clinicians and patients or their families about treatment decisions and is particularly common in intensive care units (ICUs), in the form of `futility disputes' between families and medical clinicians about decisions to terminate the active treatment of a dying family member. More common, but less prominent in the literature, is conflict within the medical profession about patient care goals and treatment. We contend that managing the plurality of medical interests is essential in achieving a more managed and positive experience for patients and families of the care they receive, and for achieving standards of quality and resource use. From an ethnographic study undertaken in a large ICU in Sydney, Australia, we found that the knowledge and practice differences of multiple medical decision-makers generated conflict, inconsistency of practice and subjectivity of decision-making that impeded coherent clinical decision-making and integrated patient care planning, coordination and care review. Improving patients' and families' experience of care requires medical clinicians and medical managers to accept responsibility for institutionalizing effective communication and decision-making processes within clinical networks and between clinical and managerial domains. Thus, strategies to improve patient care will need to extend beyond the medical profession to incorporate administrative management. We conclude that restructuring communication and decision-making processes is imperative to achieve clinical accountability in the workplace and systems accountability in the organization.

Physician knowledge of Rome symptom criteria for irritable bowel syndrome is poor among non-gastroenterologists

Rome I criteria are highly specific for irritable bowel syndrome (IBS) when red flag signs and symptoms are absent. Physician knowledge of Rome criteria may reduce diagnostic testing. We assessed: (i) physician knowledge of Rome criteria among internists, gastroenterologists and surgeons; (ii) laboratory and endoscopical testing suggested by physicians for sample IBS patients. Physicians of all training levels in internal medicine, gastroenterology, and surgery completed an anonymous questionnaire at a University Medical Center. Subjects were asked to identify Rome criteria among distracters. Sample IBS patients were presented, and physicians were asked to suggest a diagnostic workup based on the choices provided on the questionnaire. Rome knowledge was highest among gastroenterologists and lowest among surgeons. Physicians suggested endoscopical procedures in 67% of IBS patients with diarrhoea and in 46% with constipation. There was no difference among specialties in amount of laboratory or endoscopical testing suggested. Knowledge and use of the Rome criteria or their positive predictive value (PPV) for IBS did not correlate with reduced diagnostic testing. Education regarding the Rome criteria should be extended to surgical specialists who are likely to evaluate and operate on IBS patients. Endoscopical evaluation of IBS patients may be excessive.
