Incidence, duration and causes of intensive care unit admission following pulmonary resection for malignancy.

Abstract

We assessed the overall incidence and duration of ICU admission following pulmonary resection and attempted to identify patients requiring prolonged ICU stay. Analysis of prospectively collected data on all patients undergoing pulmonary resection for suspected malignant disease that subsequently required ICU admission between March 2002 and October 2003. Of 170 patients 52 (30%) needed intensive care post-operatively: 21 (12%) for less than 24 h and 31 (18%) for more, for which group the average length of stay was 11.3 days. There was no significant difference between the patient groups at ICU admission in terms of median APACHE II scores (12 vs. 14), gas exchange (PaO2/FIO2, 441 vs. 364 mmHg), estimated post-operative absolute FEV1 (1.62 vs. 1.31 l) or predicted percentage FEV1 (61.8% vs. 44.3%). Mean ICU cost was 1,838 sterling pounds vs. 25,974 sterling pounds per admission, respectively. Following pulmonary resection some 18% of patients need a protracted ICU stay at considerable cost. Neither severity of illness scoring, indices of gas exchange at ICU admission, nor predicted post-operative FEV1 identifies such patients.
