Objectives: This study aimed to evaluate trauma care capabilities at the primary care level in Muscat, Oman, using World Health Organization guidelines. Methods: This descriptive cross-sectional study was conducted between January and March 2015 at eight primary health centres in Seeb. An English-language questionnaire was distributed to the medical officer or nurse in charge at each centre to determine the number of staff, total population being served, number of emergency trauma cases and availability of ambulances. Subsequently, 10 doctors from each health centre were randomly selected to assess the availability of physical resources as well as their trauma skills and knowledge. Results: There were limited physical and human resources for the management of trauma and a complete absence of trauma administrative functions, such as local trauma registries or quality improvement activities. Conclusion: This study highlighted the need to introduce national guidelines and improve the delivery of trauma services in Oman.
