To investigate the associations between nurse staffing and the incidence and severity of hypoxaemia, arterial hypotension and bradycardia of postoperative patients during their postanaesthesia care unit stay. Nurse understaffing has been associated with adverse patient outcomes in a variety of hospital settings. In the postanaesthesia care unit, nursing shortage is common and can be related to compromised prevention, detection and treatment of adverse events. Observational, single-centre, prospective study that adhered to Strengthening the Reporting of Observational studies in Epidemiology checklist (see Supporting information Appendix S1); 2,207 patients admitted to the postanaesthesia care unit of a tertiary care hospital over a 5-month period were enrolled. Incidence of hypoxaemia (arterial oxygen saturation <95%), arterial hypotension (systolic blood pressure <90 mmHg) and bradycardia (heart rate <50 beats per minute), along with episode severity, was recorded. Patients were classified into three groups as follows: sufficient staffing, low and high understaffing. Risk for hypoxaemia, arterial hypotension and bradycardia was adjusted according to patient, anaesthesia and operation characteristics. The incidence of hypoxaemia...Continue Reading
