RESUMO
HYPOTHESIS: Risk factors for Candida infection in surgical intensive care units (SICUs) change over time. Risk factor progression may influence Candida colonization and infection. DESIGN: Multicenter cohort survey. SETTING: Three urban teaching institutions. PATIENTS: A total of 301 consecutively admitted patients in SICUs for 5 or more days. MAIN OUTCOME MEASURES: Assessment of patients on SICU days 1, 3, 4, 6, and 8 and SICU discharge for risk factors, Candida colonization, and antifungal use. Candida colonization status was categorized as noncolonized (NC), locally colonized (LC) if 1 site was involved, and disseminated infection (DI) if 2 or more sites or candidemia were involved. RESULTS: The most frequent risk factors in the 301 patients enrolled were presence of peripheral and central intravenous catheters, bladder catheters, mechanical ventilation, and lack of enteral or intravenous nutrition. Early risk factors included total parenteral nutrition or central catheter at SICU day 1 and previous SICU admissions or surgical procedures. Peak number of risk factors (mean +/- SD) were as follows: 7.2 +/- 2.6 in NC (n = 229), 9.2 +/- 2.3 in LC (n = 45), and 9.2 +/- 2.6 in DI (n = 27). These numbers were reached at day 8 in the NC and LC groups and day 4 in the DI group. The LC and DI groups had more risk factors on each SICU day than the NC group and longer median SICU length of stay (28 days in the DI group vs 11 and 19 days in the NC and LC groups, respectively). Antifungal therapy, while used most frequently in the DI group, was initiated later for this group than in NC and LC groups. CONCLUSIONS: Risk factors for Candida infection in SICU patients change over time. Patients with DI demonstrate a greater number of and more rapid increase in risk factors than patients in the LC and NC groups. Presence of early risk factors at the time of SICU admission, a high incidence of risk factors, or a rapid increase in risk factors should prompt clinicians to obtain surveillance fungal cultures and consider empirical antifungal therapy.

OBJECTIVE: To quantify the incidence and specify the types of medication administration errors from a list of error-prone medications and to determine if patient harm resulted from these errors. DESIGN: An observational evaluation. SETTING: Five intensive care units (ICUs) in the United States. PATIENTS AND PARTICIPANTS: Eight hundred fifty-one patients who were at least 18 years of age and admitted to surgical, medical or mixed ICUs during a 3 month period were included. INTERVENTIONS: None. MEASUREMENTS AND RESULTS: A list of error-prone medications was adapted from the literature and evaluated for medication errors and patient harm. Of 5,744 observations in 851 patients, 187 (3.3%) medication administration errors were detected. the therapeutic classes most commonly associated with errors were vasoactive drugs 61 (32.6%) and sedative/analgesics 48 (25.7%). The most common type of error was wrong infusion rate with 71 (40.1%) errors. Twenty-one errors did not reach the patient and 159 reached the patient but did not result in harm, increased monitoring or intervention. Five errors required increased patient monitoring and two required intervention. None of the errors resulted in patient death. CONCLUSIONS: This multicenter evaluation found fewer medication administration errors than the published literature, possibly due to the varying observational techniques and pharmacist involvement. Lorazepam and wrong infusion rates are associated with errors that occurred frequently, resulted in the greatest potential for harm and were common oversights in the system. These errors should be considered potential areas for betterment in the medication use process to improve patient safety.
