Abstract
Background
Tetanus is a vaccine-preventable infectious disease associated with high mortality rates. Increased vaccination coverage globally and locally has resulted in substantial declines in the number of individuals diagnosed with tetanus. We report annual trends in tetanus admissions and deaths over a decade at a national referral hospital in Uganda.
Methods
This was a retrospective cohort study, using data from an electronic database of patients admitted to medical wards at a national referral hospital between 2011 and 2020. Data were abstracted on demographic characteristics, that is, length of hospital stay and mortality outcome. Admission and mortality rate trends were analyzed using the Mann-Kendall’s trend test, whereas Kaplan-Meier survival curves were used to compare gender survival rates.
Results
During the study period, 459 individuals were admitted with tetanus. Of these, 85.8% (394 of 459) were males, and 26.1% (120 of 459) were aged 20 years or less. Overall, 48.8% (224 of 459) participants died, 85.3% (191 of 224) of whom were males (85.3%, n = 191), although females had a higher mortality rate (50.8%, 33 of 65 vs 48.5%, 191 of 394). Those aged 31–40 years accounted for 23.7% (53 of 224) of the deaths; and 88.7% (197 of 224) of the deaths occurred within the first 7 days of admission. The total number of tetanus admissions declined (TauA = −.6444, P = .0116). However, mortality rates remained stable (TauA = .0222, P > .999). The average length of hospital stay was 8.1 days (standard deviation, 7.5; range, 1–46).
Conclusions
Although tetanus admissions declined, mortality rate remained high. Males were disproportionately affected. We recommend quality-of-care audits for inpatient care improvement and more research on the determinants of infection and mortality to inform vaccination for at-risk men.
