A Quality Improvement Study to Improve Oxygen Prescription in the PICU of a Tertiary Care Centre in Delhi, India

Introduction Oxygen has been gravely misused since its inception as a therapeutic agent. There is a deficit of audits and baseline data for the Indian population, especially in the pediatric age group, which doesn’t allow for standardization of protocols and guidelines. Objective Our study aimed at increasing valid prescription rates to 90% by implementation of quality improvement interventions, and assessing knowledge and perception of healthcare workers towards oxygen therapy. Methodology It followed a before-and-after prospective observational study model where baseline audit data was compared with data observed after the implementation of quality improvement strategies. The data was collected through an audit of the medical records of all pediatric patients receiving oxygen therapy in the PICU. Knowledge and perception of healthcare workers about oxygen therapy were assessed via a self-designed questionnaire. The study was undertaken in three phases, including Quality Improvement (QI) team formation and data collection, root cause analysis, and implementation of Plan-Do-Study-Act (PDSA) cycles. Observations and results In the baseline audit, 1.4% of the prescriptions were complete and valid. Subsequently, over the course of four PDSA cycles, valid prescription rates increased; 62.07% in the first, 79.51% in the second, 81.81% in the third, and 91.42% in the fourth cycle respectively. After applying the chi-square test to compare PDSA4 and baseline data, the p-values for written prescriptions and target saturation were found to be statistically significant. In the healthcare worker survey, we found that 100% of them were aware of indications of oxygen prescription, FiO2, and side effects of excessive usage of oxygen therapy, 95% were aware of conditions affecting pulse-oximetry in the pediatric age group, and 75% knew about target saturation and its significance and the procedure to change alarm settings on the monitor. Conclusion Currently, there exists a lack of effective oxygen prescription audits, especially in India, which can be attributed to a lack of awareness and partly, a lack of initiative. Quality improvement initiatives are effective in improving the valid oxygen prescription rate. However, sustained goals can be achieved through regular audits only.
