Is social capital as perceived by the medical director associated with coordination among hospital staff? A nationwide survey in German hospitals.

Effective coordination among all members of hospital staff has been shown to be associated with better quality of care. The literature indicates that social capital, a form of organizational resource, may facilitate the task of coordination. However, to the best of our knowledge, no study has yet examined this link within a healthcare setting. Thus, the objective of this study was to analyze the relationship between social capital and coordination among hospital staff, as perceived by the medical director being a key informant of the hospital. In 2008, we surveyed the medical directors of 1224 German hospitals by the use of a standardized questionnaire. We conducted stepwise multivariate linear regression and controlled for hospital size, ownership and teaching status. In total, 551 medical directors (45%) responded to the survey. We found social capital to be a significant predictor of coordination (β = 0.444, p < 0.001). The regression model explained 28% of the variance in coordination. Higher levels of social capital can be associated with better coordination among members of hospital staff, as perceived by the medical director. Therefore, investment in social capital may facilitate better organization of work processes in hospitals and may therefore help to improve patient outcomes. However, longitudinal studies are needed in order to explain the causal relationship between social capital and coordination among hospital staff.
