Abstrakt:	Introduction: In Sierra Leone, the lack of information on pulmonary embolism (PE) limits the access to evidence-based standard of diagnostic work-up and management of the disease. The objective of this study was to describe the clinical characteristics and management of acute pulmonary embolism in our setting and to determine whether the pre-test probability scoring algorithms were used prior to Computed Tomography Pulmonary Angiogram (CTPA) request. Methods: This retrospective observational study was conducted on CTPA-confirmed PE patients admitted to the Intensive Care Unit, Choithrams Memorial Hospital, in Freetown, Sierra Leone between July 2014 to June 2019. Clinical data, and pertinent investigations related to PE were determined. CTPA findings were correlated with the patient's hemodynamic status. The calculated pretest clinical probability scores (PCPS) for each patient were compared to the CTPA results. Results: CTPA-confirmed PE in the study cohort was 79, with a rate of 16 new PE per year. The frequency of PE was 1.9% of the total hospital admission per year. The mean age was 64.1 ± 17.9 years, median age was 63.3years (range: 23-89 years), with 55.7% of the cohort being females. Dyspnea (78.5%) and tachycardia (69.6%) were the commonest signs and symptoms documented, with immobilization (34.2%) being the prevalent risk factor, while hypertension (48.1%) was the most common co-morbidity. The PCPS algorithm was underutilized, as "Wells Score" was documented in only 9.5% while "modified Geneva score" was never used by hospital physicians. PE with hemodynamic stability was significantly more common than PE with unstable hemodynamic status [55 (69.6%) vs 24 (30.4%), p=0.015]. All patients were managed only with anticoagulants. The overall in-hospital mortality was 17.7%. Conclusion: Since PCPS was hardly calculated by doctors in the diagnosis of PE, the study showed that the diagnostic algorithm for suspected PE was infrequently used in clinical practice. The use of empirical judgement by doctors in requesting for CTPA may have accounted for low rate in the diagnosis of PE per year. The establishment of P.E registry in Sierra Leone is imperative.
