Culture that facilitates change: A mixed methods study of hospitals engaged in reducing cesarean deliveries

Abstract

PURPOSE Large-scale efforts to reduce cesarean deliveries have shown varied levels of impact; yet understanding factors that contribute to hospitals’ success are lacking. We aimed to characterize unit culture differences at hospitals that successfully reduced their cesarean rates compared with those that did not. METHODS A mixed methods study of California hospitals participating in a statewide initiative to reduce cesarean delivery. Participants included nurses, obstetricians, family physicians, midwives, and anesthesiologists practicing at participating hospitals. Hospitals’ net change in nulliparous, term, singleton, and vertex cesarean delivery rates classified them as successful if they achieved either a minimum 5 percentage point reduction or rate of fewer than 24%. The Labor Culture Survey was used to quantify differences in unit culture. Key informant interviews were used to explore quantitative findings and characterize additional cultural barriers and facilitators. RESULTS Out of 55 hospitals, 37 (n = 840 clinicians) meeting inclusion criteria participated in the Labor Culture Survey. Physicians’ individual attitudes differed by hospital success on 5 scales: best practices (P = .003), fear (P = .001), cesarean safety (P = .014), physician oversight (P
