Abstract
As a clinical indicator, unplanned admission to the Intensive Care Unit from the operating room has been thought to reflect the quality of anaesthesia care intraoperatively. To explore this concept, we examined all such admissions at three hospitals over a three-month period. Cases were classified according to the Victorian Consultative Council on Anaesthetic Mortality and Morbidity (VCCAMM) classification system and an assessment was made as to whether the admission was inevitable or not. Demographic data were collected as well as co-morbidities, severity of illness, length of stay, discharge functional status and destination.
There were 165 admissions identified: 55.8% were male, the median age was 63.5 years (range 15–90). There were 24 in-hospital deaths: 151 patients suffered serious morbidity or mortality. In 32 patients (19.4%), the morbidity or mortality was considered at least partially anaesthetic-related, and in 20 (12.1 %), under the control of the anaesthetist. There were 28 admissions (17.0%) with a further 9 anaesthetic-related admissions (5.5%) which were considered potentially avoidable. Avoidable anaesthetic-related admissions were due to drug overdosage (5 cases), drug error (1 case), problems relating to preoperative assessment (1 case), aspiration (1 case) and pulmonary oedema (1 case).
These findings suggest that unplanned admission to the Intensive Care Unit from the operating room is not a satisfactory indicator of quality of care by the anaesthesia team. This indicator appears to represent mainly the surgical and medical conditions of the patients, and their complications. Only one in twenty unplanned admissions in this series were potentially avoidable due to complications of the anaesthetic or the postoperative analgesia.
