Summary Background Risk of mortality following surgery in patients across Africa is twice as high as the global average. Most of these deaths occur on hospital wards after the surgery itself. We aimed to assess whether enhanced postoperative surveillance of adult surgical patients at high risk of postoperative morbidity or mortality in Africa could reduce 30-day in-hospital mortality. Methods We did a two-arm, open-label, cluster-randomised trial of hospitals (clusters) across Africa. Hospitals were eligible if they provided surgery with an overnight postoperative admission. Hospitals were randomly assigned through minimisation in recruitment blocks (1:1) to provide patients with either a package of enhanced postoperative surveillance interventions (admitting the patient to higher care ward, increasing the frequency of postoperative nursing observations, assigning the patient to a bed in view of the nursing station, allowing family members to stay in the ward, and placing a postoperative surveillance guide at the bedside) for those at high risk (ie, with African Surgical Outcomes Study Surgical Risk Calculator scores ≥10) and usual care for those at low risk (intervention group), or for all patients to receive usual postoperative care (control group). Health-care providers and participants were not masked, but data assessors were. The primary outcome was 30-day in-hospital mortality of patients at low and high risk, measured at the participant level. All analyses were done as allocated (by cluster) in all patients with available data. This trial is registered with ClinicalTrials.gov , NCT03853824 . Findings Between May 3, 2019, and July 27, 2020, 594 eligible hospitals indicated a desire to participate across 33 African countries; 332 (56%) were able to recruit participants and were included in analyses. We allocated 160 hospitals (13 275 patients) to provide enhanced postoperative surveillance and 172 hospitals (15 617 patients) to provide standard care. The mean age of participants was 37·1 years (SD 15·5) and 20 039 (69·4%) of 28 892 patients were women. 30-day in-hospital mortality occurred in 169 (1·3%) of 12 970 patients with mortality data in the intervention group and in 193 (1·3%) of 15 242 patients with mortality data in the control group (relative risk 0·96, 95% CI 0·69–1·33; p=0·79). 45 (0·2%) of 22 031 patients at low risk and 309 (5·6%) of 5500 patients at high risk died. No harms associated with either intervention were reported. Interpretation This intervention package did not decrease 30-day in-hospital mortality among surgical patients in Africa at high risk of postoperative morbidity or mortality. Further research is needed to develop interventions that prevent death from surgical complications in resource-limited hospitals across Africa.

Tetanus is a potentially severe but preventable infection. In resource-rich settings, vaccination programmes have reduced tetanus to a rare disease, though still carrying an overall mortality of some 13%. However, in low income settings, tetanus remains common, and is a significant cause of mortality—though major World Health Organisation programmes are successfully targeting neonatal disease. Data concerning the frequency and outcomes of non-neonatal tetanus in low income settings are very sparse. We aimed to utilize a unique intensive care unit-based dataset to elicit clinical and demographic features and mortality in a large cohort of tetanus patients admitted over an eleven year period to a single hospital centre in a rural low-income setting in northern Uganda. A total of 268 patients with tetanus were admitted to the Intensive Care Unit at St Mary’s Hospital, Lacor between 2005 and 2015; the records of 190 were retrievable and had sufficient information to be assessed. 29 were neonates (median age 7 days, IQR 0), 52 children (1-16yrs; median age 11 years, IQR 4.5) and 109 were adults (median age 42 years, IQR 23). There was no seasonal pattern in the frequency of admissions. Of the 190 patients, 69 had endotracheal intubation with intermitent positive pressure ventilation, and 57 patients had central line placement. The overall mortality was 51.5% – 72.4% in neonatal disease, 25% in children and 57.8% in adults. The requirements for neither central line insertion, nor endotracheal intubation, nor intermittent positive pressure ventilation were independently linked to mortality rates. By contrast with neonatal and childhood disease, there was a marked male preponderance in adult tetanus—94 males and 15 females (gender difference p < 0.001) – and although year-on-year breakdown suggested no obvious upward or downward trend over the span of our study in total numbers of tetanus admissions, a trend towards an increasing incidence of adult tetanus was apparent. These findings confirm that adult tetanus remains a major problem in rural low income settings, particularly in males, and suggests that more resources should be devoted to vaccination programmes targeting men.
