Oxygen as a drug and scarce commodity: Do we use it rationally?

Résumé

BACKGROUND: Medical grade oxygen is classified as a drug and needs to be prescribed by a qualified healthcare professional. Oxygen therapy is prescribed to people who cannot maintain normal blood oxygen saturation while breathing atmospheric air. The coronavirus disease 2019 (COVID-19) pandemic highlighted the importance of the rational use of this scarce commodity. This study investigated oxygen therapy practices in adult ward patients. METHODS: A cross-sectional study design with an analytical component was used in the adults wards at a National District Hospital and the Pelonomi Academic Hospital in Bloemfontein. Data were collected from patient files, interviews and oxygen measurements of adult patients that received oxygen. RESULTS: One hundred and fifteen patients were included in the study, of whom 47.0% received oxygen without an oxygen prescription. Around 62.3% of the patients with prescriptions did not receive oxygen as prescribed. The prescriptions and oxygen administration for COVID-19 patients were better than for non-COVID-19 patients. A quarter of the patients possibly received oxygen therapy unnecessarily. CONCLUSION: Poor oxygen therapy practices were identified, including prescription errors, oxygen administration errors and oxygen wastage. A protocol should be developed and implemented for the prescription and administration of oxygen therapy. Training should occur to prevent oxygen wastage.Contribution: This study highlighted poor oxygen practices and prescriptions, as well as oxygen wastage in the absence of local oxygen therapy guidelines.
