Abstract

Background Oxygen is an essential medication that should be prescribed and administered according to evidence-based guidelines to prevent both hypoxaemia and hyperoxia. Despite the availability of the British Thoracic Society (BTS) guideline, deficiencies in physicians' knowledge of oxygen therapy remain common and may compromise patient safety. This study aimed to assess changes in physicians' knowledge of evidence-based oxygen therapy following a structured educational intervention through a closed-loop clinical audit. Methods A prospective closed-loop clinical audit was conducted in the Internal Medicine Department of Al-Managil Teaching Hospital, Sudan. A total-coverage sampling strategy was employed, with 64 physicians participating in the baseline audit and 64 physicians participating in the re-audit. Knowledge was assessed using the same structured 15-item questionnaire derived from BTS oxygen therapy standards. Following the baseline assessment, a one-month multifaceted educational intervention was implemented. The second audit cycle was conducted using the same assessment tool, and physicians' knowledge before and after the intervention was compared. Results Knowledge improved across all fifteen assessed BTS standards following the educational intervention. The greatest improvement was observed in prescribing target oxygen saturation ranges for all admitted patients, which increased from 16 (25.0%) to 37 (57.8%) (χ² = 14.20, p < 0.001). Significant improvements were also observed in knowledge of oxygen humidification, pulse oximetry limitations, arterial blood gas interpretation, oxygen prescription documentation, and oxygen-induced hypercapnia. Overall, improvements ranged from 14.1 to 32.8 percentage points across the assessed standards. Despite these gains, only one standard exceeded the predefined performance target, indicating persistent knowledge gaps requiring further quality improvement. Conclusion A structured educational intervention was associated with significant improvements in departmental-level physicians' knowledge of evidence-based oxygen therapy. However, persistent deficiencies in several key domains highlight the need for continuous professional education, regular re-audit, and ongoing quality improvement initiatives to strengthen guideline adherence and promote safer oxygen prescribing practices.
