To characterize the burden of post-stroke aspiration pneumonia (PSAP), its risk factors, and its impact on clinical outcomes in a Zambian hospital.
The burden of cerebrovascular disease is rising in sub-Saharan Africa, where modern acute stroke interventions are often unavailable. Preventing post-stroke complications such as aspiration pneumonia may hold promise for improving outcomes after stroke in resource-limited settings.

We conducted a prospective cohort study of adults with stroke admitted to University Teaching Hospital (Lusaka, Zambia) between 12/2019-3/2020. Demographic and clinical parameters were captured serially over the admission, including NIH Stroke Scale (NIHSS), Glasgow Coma Scale (GCS), Modified Rankin Scale (mRS), and nine PSAP indicators (e.g. fever, cough, tachypnea, etc). Possible PSAP was defined as ≥2 indicators present, and PSAP as ≥4 present. T-tests and chi-square tests were used to compare clinical parameters between participants with and without PSAP. Logistic regression was used to assess the relative contributions of age, sex, PSAP status, admission NIHSS, mRS, and GCS on inpatient mortality.

125 participants were enrolled: 61% female, mean age 60+/-16 years, 54% ischemic stroke. Thirty-eight (30%) had PSAP, and 32 (25%) had possible PSAP. Swallow screening was documented for only 4 participants. Participants with PSAP were older (67.7 vs 56.1 years, p<0.001), and on admission had higher NIHSS (25.9 vs 16.7, p<0.001), lower GCS (8.1 vs 12.1, p<0.001), and higher mRS (4.96 vs 4.32, p<0.001). PSAP predicted increased inpatient mortality (PSAP 59%, possible PSAP 39%, no PSAP 8%, p<0.001) independent of age, sex, and initial stroke severity (OR=3.07, 95% CI=1.32-7.15, p=0.009).

PSAP is a frequent complication of acute stroke in Zambia, especially among older participants with more severe presentations. PSAP predicts significantly increased inpatient mortality independent of initial stroke severity, suggesting that interventions mitigating PSAP may improve stroke outcomes in Zambia and other resource-limited settings.
