CHAVES, Jéssica et al. An Audit of Oxygen Therapy Practices in an Internal Medicine Ward. Medicina Interna [online]. 2019, vol.26, n.4, pp.23-27. ISSN 0872-671X.

Introduction: Oxygen (O2) prescription is frequent in an Internal Medicine ward. Recommendations such as the British Thoracic Society establish the appropriate use of O2 in health care. Our objective was to evaluate O2 therapy procedures in an Internal Medicine ward, in light of 2017  British Thoracic Society recommendations. Methods: We conducted an observational study, during a period of 48 hours, which included patients admitted to the Internal Medicine ward of Hospital Central do Funchal, under oxygen therapy, with or without prescription. We analysed: 1) the reason for the prescription, 2) the type of prescription (fixed dose versus peripheral O2 interval saturation oriented dose), 3) accordance between prescription and administration, and 4) monitoring (prescription and registration). Results: From a total of 116 hospitalized patients, 114 (98%) had O2 prescription. Six patients (5.3%) had no hypoxemia, and 57 (50%) had no hypoxemia assessment registration. From the 114 patients with a prescription, only 38 (33%) had targeted saturation range objectives. Of these, 61% did not have prescribed the maximum saturation target and only 8% had the two interval limits defined. From 76 patients (67%) with fixed dose prescription, none had the registrations of the four recommended parameters. Eight (11%) did not receive O2 therapy and 39 (51%) were receiving an O2 dose different from the one prescribed. Monitoring was performed, on average, 2.16 times in a 24 hours period. Five patients (4%) had no monitoring record. Conclusion: The majority of O2 therapy prescriptions did not meet the current recommendations. Therefore, practice optimization is needed in the prescription, administration and monitoring of O2 therapy steps. It is necessary to raise awareness among health professionals and reprise outcome audition.
