AbstractTo determine whether on-site physician staffing changed test and procedure use and improved patient outcome in a community hospital intensive care unit (ICU), we studied all ICU admissions for matched periods before and after the staffing change. Compared with the 463 year-1 patients, the 491 year-2 patients were no more likely to receive life-support interventions (respirators, dialysis, or pacemakers), but had substantially more monitoring interventions, such as pulmonary artery catheters (22% v 2%, P less than .0001) and arterial catheters (9% v 0%, P less than .0001). After controlling for factors that predicted death (age, mental status at time of admission, reason for ICU admission), year-2 patients were significantly more likely to survive the ICU and subsequent hospital stay (P = .01). Nearly all of the improvement of survival rate took place among patients with intermediate likelihoods of death; this improved survival rate persisted at the 12-month follow-up (P = .01).
