  • Title: Complications of care in a medical intensive care unit.
    Author: Rubins HB, Moskowitz MA.
    Journal: J Gen Intern Med; 1990; 5(2):104-9. PubMed ID: 2313401.
    Abstract:
    OBJECTIVE: To determine the frequency and nature of complications of care in the medical intensive care unit (MICU). DESIGN: Prospective, observational study. SETTING: Seven-bed MICU in a teaching and referral VA hospital. PATIENTS: 295 consecutive patients admitted to the MICU during a ten-month study period. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Forty-two patients (14%, 95% confidence interval 13%, 16%) experienced one or more complications during their MICU stays. Compared with other MICU patients, those experiencing complications tended to be older (mean age +/- SD: 63.6 +/- 10.1 years vs 59.3 +/- 14.0 years, p less than 0.02) and more acutely ill (mean Acute Physiology Score +/- SD: 18.3 +/- 8.0 vs 12.5 +/- 8.0, p = 0.0001). These patients also had significantly longer MICU lengths of stay (mean +/- SD: 12.3 +/- 14.7 days vs 3.1 +/- 4 days, p less than 0.0001) and higher hospital mortality rates (67% vs 27%, p less than 0.001). The 67% mortality rate among patients with complications significantly exceeded the expected mortality rate of 46% (calculated from the APACHE risk equation). CONCLUSION: Complications of care in the MICU are not rare and may independently contribute to in-hospital mortality. The potential for complications must be recognized when considering ICU care.
