Association of organizational culture and climate with variation in the clinical outcomes of collaborative care for maternal depression in community health centers

Background Organizational factors may help explain variation in the effectiveness of evidence-based clinical innovations through implementation and sustainment. This study tested the relationship between organizational culture and climate and variation in clinical outcomes of the Collaborative Care Model (CoCM) for treatment of maternal depression implemented in community health centers. Method Organizational cultures and climates of 10 community health centers providing CoCM for depression among low-income women pregnant or parenting were assessed using the organizational social context (OSC) measure. Three-level hierarchical linear models tested whether variation in culture and climate predicted variation in improvement in depression symptoms from baseline to 6.5-month post-baseline for N = 468 women with care ±1 year of OSC assessment. Depression symptomology was measured using the Patient Health Questionnaire (PHQ-9). Results After controlling for patient characteristics, case mix, center size, and implementation support, patients served by centers with more proficient cultures improved significantly more from baseline to 6.5-month post-baseline than patients in centers with less proficient cultures (mean improvement = 5.08 vs. 0.14, respectively, p = .020), resulting in a large adjusted effect size of d adj = 0.78. A similar effect was observed for patients served by centers with more functional climates (mean improvement = 5.25 vs. 1.12, p
