Objective:

to describe the patients with cardiovascular disease and the need for home oxygen therapy at the Fundación Cardioinfantil throughout 2018.

Methods:

a descriptive observational study. Hospitalized patients at Fundación Cardioinfantil from January 1, 2018, to December 31, 2018, diagnosed with cardiovascular disease and presenting their first request for home oxygen. Sociodemographic, clinical, laboratory, and imaging variables along with inpatient days and length of stay in the ICU, were collected.

Results:

192 patients were studied. The median age was 74 years (IQR: 64, 25 - 81). The BMI was 25.98 kg/m2 (IQR: 22.74 - 29.67). A total of 47.9% of the population had coronary disease; 49.5% had heart failure; 27.1% had PH, 23% had OSAH, 6.3% had PTE and 16.7% had COPD. The average BNP was 1,430 SD 1,302. The average LVEF was 35.43% SD 15.35 and the median PASP was 53 mmHg (IQR 43 - 65). Altogether, 71.9% required ICU treatment. The average hospital stay was 14.08 days SD 10.1 days. A total of 20.8% of the patients had a PaO2 less than 55 mmHg; 77.1% belonged to the contributive social security regimen.

Conclusions:

we found that only a minority of the study patients for whom CHOT was ordered met the usually accepted criteria. Half of the patients had heart failure, most with reduced LVEF and elevated BNP, criteria which are not currently used for prescribing CHOT. More studies should be performed on the indications for supplementary oxygen therapy in this population. (Acta Med Colomb 2022; 47. DOI:https://doi.org/10.36104/amc.2022.2207).
