Surgical Safety Checklist Use and Post-Caesarean Sepsis in the Lake Zone of Tanzania: Results from Safe Surgery 2020.

BACKGROUND: Maternal sepsis accounts for significant morbidity and mortality in lower income countries, and caesarean delivery, while often necessary, augments the risk of maternal sepsis. The aim of this study was to investigate the effect of Safe Surgery 2020 surgical safety checklist (SSC) implementation on post-caesarean sepsis in Tanzania. METHODS: We conducted a study in 20 facilities in Tanzania's Lake Zone as part of the Safe Surgery 2020 intervention. We prospectively collected data on SSC adherence and maternal sepsis outcomes from 1341 caesarian deliveries. The primary outcome measure was maternal sepsis rate. The primary predictor was SSC adherence. Multivariable logistic regression was used to estimate independent associations between SSC adherence and maternal sepsis. RESULTS: Higher SSC adherence was associated with lower rates of maternal sepsis (<25% adherence: 5.0%; >75% adherence: 0.7%). Wound class and facility type were significantly associated with development of maternal sepsis (Wound class: Clean-Contaminated 3.7%, Contaminated/Dirty 20%, P = 0.018) (Facility Type: Health Centre 5.9%, District Hospital 4.5%, Regional Referral Hospital 1.7%, P = 0.018). In multivariable analysis, after controlling for wound class and facility type, higher SSC adherence was associated with lower rates of maternal sepsis, with an adjusted odds ratio of 0.17 per percentage point increase in SSC adherence (95% CI: 0.04, 0.79; P = 0.024). CONCLUSIONS: Adherence to the SSC may reduce maternal morbidity during caesarean delivery, reinforcing the assumption that surgical quality interventions improve maternal outcomes. Future studies should continue to explore additional synergies between surgical and maternal quality improvement.

Improving surgical quality in low-income and middle-income countries: why do some health facilities perform better than others?

BACKGROUND: Evidence on heterogeneity in outcomes of surgical quality interventions in low-income and middle-income countries is limited. We explored factors driving performance in the Safe Surgery 2020 intervention in Tanzania's Lake Zone to distil implementation lessons for low-resource settings. METHODS: We identified higher (n=3) and lower (n=3) performers from quantitative data on improvement from 14 safety and teamwork and communication indicators at 0 and 12 months from 10 intervention facilities, using a positive deviance framework. From 72 key informant interviews with surgical providers across facilities at 1, 6 and 12 months, we used a grounded theory approach to identify practices of higher and lower performers. RESULTS: Performance experiences of higher and lower performers differed on the following themes: (1) preintervention context, (2) engagement with Safe Surgery 2020 interventions, (3) teamwork and communication orientation, (4) collective learning orientation, (5) role of leadership, and (6) perceived impact of Safe Surgery 2020 and beyond. Higher performers had a culture of teamwork which helped them capitalise on Safe Surgery 2020 to improve surgical ecosystems holistically on safety practices, teamwork and communication. Lower performers prioritised overhauling safety practices and began considering organisational cultural changes much later. Thus, while also improving, lower performers prioritised different goals and trailed higher performers on the change continuum. CONCLUSION: Future interventions should be tailored to facility context and invest in strengthening teamwork, communication and collective learning and facilitate leadership engagement to build a receptive climate for successful implementation of safe surgery interventions.
