Abstract

Background/Aims: Home oxygen therapy (HOT) costs a great deal every year and demand for the service is growing. In Korea, health insurance has covered HOT since November 1, 2006. The objective of this study was to evaluate clinical features of patients who used long-term HOT due to chronic respiratory failure and to determine the appropriateness of oxygen prescriptions. Methods: Between November 2006 and April 2010, patients prescribed long-term HOT were enrolled in the study at a tertiary university referral hospital and their medical records and telephone survey information were evaluated. In total, 340 patients were evaluated retrospectively. Results: Regarding the initial indications for HOT, their mean $PaO_2$ was 49.8 mmHg and mean $SpO_2$ was 82.2%. Underlying diseases included chronic obstructive pulmonary disease (COPD, 19.8%), lung cancer (12.6%), and interstitial lung disease (11.2%). The admission rate within 1 year was 53.4% and the average number of admissions was 1.64/patient. Other underlying diseases for which oxygen was prescribed, despite not meeting the insurance coverage criteria, were lung cancer (36.6%) and interstitial pneumonia (16.6%). Conclusions: Home oxygen prescriptions have increased since health insurance coverage was extended. However, cases of oxygen prescriptions frequently do not meet the coverage criteria. It is important to discuss extending the coverage criteria to other disease groups, such as interstitial lung disease and lung cancer, in terms of cost-effectiveness. Further, physicians prescribing oxygen therapy should be educated regarding the criteria.
