Auditoría de oxígenoterapia de pacientes hospitalizados en establecimientos del Servicio de Salud Talcahuano

Abstract

Abstract Oxygen is a commonly used drug in clinics and its use must be judicious. There are guidelines for oxygen therapy but we ignore if these are respected in our country. We conducted an audit of oxygen therapy by applying a survey to 381 patients in the three hospitals of Talcahuano Public Health Service. The day of the audit 13.7% of the hospitalized patients were on oxygen, most of them with respiratory (46.15%) or cardiovascular (25%) diseases. Indication of O2 administration was given by a physician in 88.5% and there was not registry in 3.8% of the cases. There was not foundation for supplying O2 in 13.3% of patients. A fixed dose was indicated in 75% of cases and 50% had an oximetry value as a target. Oxygen was administered in most of the cases by nasal prongs and Venturi masks. Monitoring was based on pulse oximetry in the less complex hospitals and on arterial blood gases in the tertiary hospital. 100% of patients at urgency ward were receiving a different dose from that indicated at their admission time and none of them had a registry of the new dose. Mean duration of therapy was 7.8 days. We believe our results might represent what is going on with oxygen therapy in our country; having a good foundation and monitoring, we still don t use targets and there is a bad system of registry. We think that it would be advisably to carry out audits on oxygen therapy at national level on regular basis.
