Iatrogenic events in neonates: beneficial effects of prevention strategies and continuous monitoring.

OBJECTIVES: To assess the impact of continuous incident reporting and subsequent prevention strategies on the incidence of severe iatrogenic events and targeted priorities in admitted neonates. METHODS: We performed preintervention (January 1 to September 1, 2005) and postintervention (January 1, 2008, to January 1, 2009) prospective investigations based on continuous incident reporting. Patient-safety initiatives were implemented for a period of 2 years. The main outcome was a reduction in the incidence of severe iatrogenic events. Secondary outcomes were improvements in 5 targeted priorities: catheter-related infections; invasive procedures; unplanned extubations; 10-fold drug infusion-rate errors; and severe cutaneous injuries. RESULTS: The first and second study periods included totals of 388 and 645 patients (median gestational ages: 34 and 35 weeks, respectively; P = .015). In the second period the incidence of severe iatrogenic events was significantly reduced from 7.6 to 4.8 per 1000 patient-days (P = .005). Infections related to central catheters decreased significantly from 13.9 to 8.2 per 1000 catheter-days (P < .0001), as did exposure to central catheters, which decreased from 359 to 239 days per 1000 patient-days (P < .0001). Tenfold drug-dosing errors were reduced significantly (P = .022). However, the number of unplanned extubations increased significantly from 5.6 to 15.5 per 1000 ventilation-days (P = .03). CONCLUSIONS: Prospective, continuous incident reporting followed by the implementation of prevention strategies are complementary procedures that constitute an effective system to improve the quality of care and patient safety.

Assessment of the value of repeated point-prevalence surveys for analyzing the trend in nosocomial infections.

OBJECTIVE: To assess the value of repeated point-prevalence surveys in measuring the trend in nosocomial infections after adjustment for case mix. SETTING: A 3,500-bed teaching facility composed of 4 acute care hospitals. METHODS: From May 1992 to June 1996, eight point-prevalence surveys of nosocomial infections were performed in the hospitals using a sampling process. The trend of adjusted nosocomial infection rates was studied for the four surveys that collected data on indwelling catheters. Adjusted rates were calculated using a logistic regression model and a direct standardization method. RESULTS: From 1992 to 1996, a total of 20,238 patients were included in the 8 point-prevalence surveys. The nosocomial infection rate decreased from 8.6% in 1992 to 5% in 1996 (P < .001). The analysis of adjusted nosocomial infection rates included 9,600 patients. Four independent risk factors were identified: length of stay greater than 12 days, hospitalization in an intensive care unit, presence of an indwelling urinary catheter, and history of a surgical procedure. After adjustment for case mix, the nosocomial infection rate still showed a downward trend (from 7.2% in 1993 to 5.1% in 1996; P = .02). CONCLUSION: Adjusted prevalence rates of nosocomial infections showed a significant downward trend during the period of this study.
