Missed Golden Hour? Proportion and Factors Associated with Timely Specialist Review of Very High-Risk Obstetric Mothers in Eastern Uganda: A Retrospective Study.

Background. Timely review of very high-risk mothers by an obstetrician within one hour of admission is very important in enabling fast decision making for emergency intervention. Any delays in review of high-risk obstetric patient such as hypertensive disorders, obstructed labour or haemorrhages increase maternal morbidity and mortality. Globally, more than 260,000 mothers die from pregnancy related causes with sub-Saharan Africa being contributing 70%. To reduce this mortality, the ministry of health of Uganda encourages urgent assessment of all high-risk pregnant mothers. This study assessed the proportion and factors associated with specialist review within one hour of very high-risk obstetric mothers at Mbale Regional Referral Hospital. Methods. A retrospective quantitative study was conducted from June to October 2025 at a tertiary Hospital in Easter Uganda. Systematic sampling was used to select files of mothers triaged as very high (red category). The minimum calculated sample size was 427, but 454 eligible files were analysed to improve precision. Social demographics obstetric characteristics and timing of specialist review ere extracted. Data were entered into excel and analysed using STATA. Descriptive statistics summarized proportions and modified Poisson regression identified factors associated with timely review at 95% CI and p<005. Results. The proportion of very high-risk mothers reviewed within one hour was 33.9 % (95% CI:29.7%-38.4%). In multivariable analysis, foetal heart monitoring conducted once was independently associated with lower likelihood of timely review (aPR=0.575,95% CI:0.334-0.988; p=0.045). No other variables showed significant association. Conclusion. Only one-third of very high-risk mothers received specialist review within one hour below national recommendations. Strengthening obstetric triage and specialist availability is essential to improving emergency obstetric care
