    "abstract": "Pulmonary embolism is a common cause of morbidity and mortality. Numerous risk factors have been identified that predispose patients to this disease. This study aims to identify these risk factors and the possible outcomes (recovery or mortality) after receiving treatment from any hospital. Healthcare is expensive in Africa, hence hindering its easy accessibility.\u00a0 PubMed, Scopus, and African Journals Online were searched from the database inception to October 2024 to identify relevant studies. A total of 719 articles were identified, for which 172 duplicate articles were removed. After screening 592 articles by title and abstract, 508 were excluded. Eighty-four articles were screened by full text to determine their eligibility. Finally, 13 articles were used in the final qualitative analysis. We included original research published in English in peer-reviewed journals from January 2000 to September 2024 that reported the risk factors and outcomes of pulmonary embolism, and studies that used computed tomography pulmonary angiography as a diagnosis of acute pulmonary embolism in patients more than 18 years old, irrespective of gender and medical or surgical condition, managed in any African hospital, were included. In total, 7650 patients were included in 13 articles, from 10 countries (Nigeria, Togo, Angola, Kenya, Cameroon, South Africa, Sierra Leone, Egypt, DR Congo, and Ethiopia), and 861 patients had pulmonary embolism. The mean age of the reported patients ranged from 40.8 to 64.4 years across the studies. There were 309 male and 552 female patients diagnosed with pulmonary embolism. The study types included in this review are retrospective studies,\u00a0cross-sectional studies, and case-control studies. Deep vein thrombosis (DVT), heart disease, immobilization, obesity, smoking, recent surgery, and malignancy were the most commonly identified risk factors across the included articles. Pulmonary embolism contributes significantly to morbidity and mortality among African patients, with key risk factors including DVT, immobilization, heart disease, obesity, smoking, recent surgery, malignancy, pregnancy, and contraceptive use. Limited diagnostic resources in low-resource settings pose a major challenge, but adopting affordable diagnostic alternatives and clinical algorithms could improve outcomes by enabling earlier diagnosis and timely treatment. The availability and implementation of a standardized PE treatment protocol will ensure quality care, decrease mortality, and increase recovery rates.",
