Health professional networks as a vector for improving healthcare quality and safety: a systematic review

Abstract

BackgroundWhile there is a considerable corpus of theoretical and empirical literature on networks within and outside of the health sector, multiple research questions are yet to be answered.ObjectiveTo conduct a systematic review of studies of professionals' network structures, identifying factors associated with network effectiveness and sustainability, particularly in relation to quality of care and patient safety.MethodsThe authors searched MEDLINE, CINAHL, EMBASE, Web of Science and Business Source Premier from January 1995 to December 2009.ResultsA majority of the 26 unique studies identified used social network analysis to examine structural relationships in networks: structural relationships within and between networks, health professionals and their social context, health collaboratives and partnerships, and knowledge sharing networks. Key aspects of networks explored were administrative and clinical exchanges, network performance, integration, stability and influences on the quality of healthcare. More recent studies show that cohesive and collaborative health professional networks can facilitate the coordination of care and contribute to improving quality and safety of care. Structural network vulnerabilities include cliques, professional and gender homophily, and over-reliance on central agencies or individuals.ConclusionsEffective professional networks employ natural structural network features (eg, bridges, brokers, density, centrality, degrees of separation, social capital, trust) in producing collaboratively oriented healthcare. This requires efficient transmission of information and social and professional interaction within and across networks. For those using networks to improve care, recurring success factors are understanding your network's characteristics, attending to its functioning and investing time in facilitating its improvement. Despite this, there is no guarantee that time spent on networks will necessarily improve patient care.

Impact of Establishing a Communication Network of Family Physicians on Level of Hba1c and FBS in Patients With Diabetes: A Randomized Clinical Trial

“…The results suggest that the coordination and sharing of information among physicians through a communication network could have a positive impact on enhanced quality of care and health of patients. The findings are consistent with the conclusion of Cunningham et al (30), which showed that integrated communication networks among specialists could promote the coordination and quality of health care services to patients. Additionally, such networks could help identify weaknesses and shortcomings related to the healthcare provided to the patients.…”

Innovation and sustainability in a large-scale healthcare improvement collaborative - seven propositions for achieving system-wide innovation and sustainability

“…This is also congruent with the literature on networks where effective networks have a compelling organising purpose (Cunningham et al, 2011;Malby et al, 2013). This is reflected in responses from the present study where LIQH is seen as more than simply a fluidly organised model that can be used as-and-when:…”

Learning Challenges Associated with Evidence-Based Practice in Rheumatology

“…Participating in formal education outside the workplace and extending professional networks may be effective in enhancing learning and EBP. In a review, Cunningham et al (2011) showed that effective professional networks contributed to the quality of care and patient safety through efficient transmission of information and social and professional interaction within and across networks.…”
