Antibiotic-impregnated catheters associated with significant decrease in nosocomial and multidrug-resistant bacteremias in critically ill patients.

OBJECTIVE: To evaluate the impact of using central venous catheters (CVCs) impregnated with the combination of minocycline and rifampin on nosocomial bloodstream infections (BSIs), morbidity, and mortality in cancer patients in the ICU. DESIGN: Prospective surveillance study consisting of the following two time periods: September 1997 through August 1998 (ie, fiscal year [FY] 1998); and from September 1998 through August 1999 (ie, FY 1999). SETTING: ICUs of a tertiary care hospital in Houston, TX. PATIENTS: Cancer patients in the medical ICU (MICU) and surgical ICU (SICU). INTERVENTIONS: ICUs started using CVCs impregnated with the minocycline-rifampin combination at the beginning of FY 1999. MEASUREMENTS AND MAIN RESULTS: The rates of nosocomial BSIs and other patients' characteristics were compared for the two study periods to determine the impact of using the impregnated catheters in the ICU. Patients' characteristics, including antibiotic use, were comparable for the two study periods in both the MICU and the SICU. The rate of nosocomial BSIs in the MICU unit decreased from 8.3 to 3.5 per 1,000 patient-days (p < 0.01), and decreased in the SICU from 4.8 to 1.3 per 1,000 patient-days (p < 0.01) in FY 1999. Nosocomial vancomycin-resistant enterococcus (VRE) bacteremia also decreased significantly (p = 0.004). Length of stay in the MICU and SICU significantly decreased in FY 1999 (p < 0.01 and p = 0.03, respectively). The duration of hospitalization decreased for MICU and SICU patients (p = 0.06 and p < 0.01, respectively). The rate of catheter-related infections decreased from 3.1 to 0.7 per 1,000 patient-days in FY 1999 (p = 0.02). The decrease in infections resulted in net savings of at least $1,450,000 for FY 1999. CONCLUSIONS: The use of antibiotic-impregnated CVCs in the MICU and SICU was associated with a significant decrease in nosocomial BSIs, including VRE bacteremia, catheter-related infections, and lengths of hospital and ICU stays.

Outcome and cost implications of cardiopulmonary resuscitation in the medical intensive care unit of a comprehensive cancer center.

Intensive care unit (ICU) resources are frequently utilized in the supportive care of hospitalized patients with cancer. Patients with cancer reportedly have poor outcomes from cardiopulmonary resuscitation (CPR). The goal of this study was to evaluate the effectiveness and patient care costs of CPR applied to patients already receiving life support in an ICU. The medical records of patients who developed cardiac arrest and underwent CPR in the ICU of a comprehensive cancer center between 1993 and 2000 were reviewed. ICU charges after the first episode of CPR were analyzed. There were 5,196 admissions to the ICU during this time; 406 (8%) of the patients underwent CPR; 67% had hematologic malignancies or had undergone hematopoietic stem cell transplantation: 256 patients (63%) died at the time of the arrest, and in 150 (37%) spontaneous circulation was restored. There were 104 patients (26%) who survived more than 24 hours but ultimately died during their hospitalization; their mean time to death was 4.3 days (95% confidence interval [CI] 2.9-5.6), and mean ICU charges were $45,877 (95% CI $24,802-$66,952). Seven patients (2%) survived to be discharged. Patients who survived after CPR and were discharged from the hospital were those who had acute ventricular dysrhythmias and were resuscitated promptly. The application of CPR to cancer patients receiving life support is costly and typically does not lead to long-term survival. Cancer patients requiring admission to an ICU should receive full supportive care short of resuscitation. Providing assurances that care will remain appropriate, aggressive, and in accordance with the patient's and family's wishes can optimize compassionate care while avoiding futile life-sustaining interventions.
