Introduction and objectives: Oxygen therapy is a significant therapy for respiratory disease. Both Continuous Home Oxygen Therapy (COT) and Home Oxygen Therapy in Other Situations (TO) are cost-effective. A 10-year retrospective study was conducted, aimed at learning about and comparing the continuation time and survival curves (median in months) within a Continuous Home Oxygen Therapy and Non-Invasive Ventilation Program and its relation with the therapy type (COT, TO), reason for the prescription (pathology) and gender. Results: 1752 patients were studied. The annual prevalence of Oxygen Therapy was 90.47/100.000/population/year. For COT the most frequent pathologies were COPD and Pulmonary Fibrosis. The continuation time was 15 months and survival time 23 months. For TO the most frequent prescription was for the treatment of cancer (pulmonary and non-pulmonary); the continuation time was 2 months and survival time 3 months. No significant statistical differences were registered regarding gender in either case, continuation and survival time. The main cause of a Continuous Positive Airway Pressure (CPAP) prescription was Obstructive Sleep Apnea / Hypopnea Syndrome (OSAHS) with a continuation time of 66 months. The main causes of the Bilevel prescription were COPD, obstructive sleep apnea-hypopnea syndrome and neuromuscular diseases, with a continuation time of 34 months. When Oxygen Therapy was added, the continuation time was 46 months. Conclusions: It is essential to know the characteristics of patients, continuation time, survival curves, reasons for dropping and the treatment and equipment prescribed for the pathology, because these data are needed for decision-making aimed at the patient and the oxygen management program.
