Leveraging sociological systems theory: integrating transformational leadership and social capital to enhance quality of care - an exploratory longitudinal study of German hospitals.

BACKGROUND

Numerous studies have examined ways to improve care quality and patient safety. Further progress could be achieved by leveraging underexplored sociological concepts. To date, transformational leadership and social capital have been examined primarily as isolated factors in healthcare research to explain variations in hospital care quality. Yet, these concepts have rarely been integrated into a broader theoretical framework. Drawing on Parsons' AGIL framework, we identified two key social prerequisites for effective healthcare organizations: goal attainment and integration. We hypothesized that hospitals meeting both criteria would deliver better care quality.

METHODS

Using a 2008 survey of medical directors in German hospitals, we measured transformational leadership (as a proxy for goal attainment) and social capital (as a proxy for integration). Data were matched with quality metrics from nationwide reports (2012-2019) on quality irregularities and quality deficiencies. Hospitals were grouped into high and low categories for both factors using a median split, and longitudinal panel analyses were conducted on 508 hospitals.

RESULTS

The combination of strong transformational leadership and high social capital was associated with significantly fewer quality irregularities, but not with quality deficiencies.

CONCLUSIONS

Our findings suggest that hospital leadership should strategically strengthen both factors to improve organizational capacity for quality improvement. This synergy likely fosters goal-oriented collective action, particularly the collaborative efforts required to enhance care quality and patient safety. Additionally, we propose that applying sociological theory offers valuable insights into the social dynamics essential for maintaining and enhancing quality and safety in healthcare settings.
