- W2474066920 abstract "Abstract Objectives: To describe the clinical and laboratory characteristics of patients on long-term home oxygen therapy followed up by the home care program of Hospital das Clinicas, School of Medicine, Universidade de Sao Paulo, during a period of 8 years, and to compare groups with and without secondary pulmonary hypertension. To estimate the cost of the program using oxygen concentrators versus oxygen cylinders provided by the hospital. Methods: A descriptive, retrospective cohort study of patients on long-term home oxygen therapy followed up from 2002 to 2009 at the Unit of Pulmonology, Children’s Institute, Hospital das Clinicas, School of Medicine, Universidade de Sao Paulo. Results: We studied 165 patients, of whom 53% were male, with the following medians: age at the beginning of oxygen therapy – 3.6 years; duration of oxygen therapy – 7 years; and survival time after beginning of oxygen therapy – 3.4 years. The main diagnoses were: cystic fibrosis (22%), bronchopulmonary dysplasia (19%), and bronchiolitis obliterans (15%). Of the 33 patients who underwent spirometry, 70% had severe obstructive lung disease. Echocardiogram was performed in 134 patients; 51% of them had secondary pulmonary hypertension. There was a statistically significant association between pulmonary hypertension and need of higher oxygen flows (chi-square, p = 0.011), and pulmonary hypertension and longer duration of oxygen therapy (Logrank, p = 0.0001). There was no statistically significant difference between survival time after the beginning of oxygen therapy and pulmonary hypertension. The average monthly costs of the program were: US$ 7,392.93 for concentrators and US$ 16,630.92 for cylinders." @default.
