Abstract

OBJECTIVES:

To assess the frequency, severity, and preventability of adverse events (AEs) detected using the Global Trigger Tool (GTT) in an acute geriatric hospital.

DESIGN:

A 6-year retrospective study.

SETTING:

An urban Spanish acute geriatric teaching hospital of 200 beds.

PARTICIPANTS:

Ten randomly selected clinical records were chosen every fortnight from January 2007 to December 2012 (1,440 records, 240 per year).

MEASUREMENTS:

Triggers, AEs, Index of the National Coordinating Council for Medication Error Reporting and Prevention (NCC MERP) categories of severity, and Likert scale to evaluate the preventability of AEs.

RESULTS:

Four hundred twenty-four AEs (categories E to I of the NCC MERP Index) were identified in 335 of the 1,440 individuals scrutinized, which corresponded to 29.4 physical injuries per 100 admissions (95% confidence interval (CI) = 25.7-34.7). Of these, 351 (91.7%) occurred 3 or more days after admission; 279 harms (65.8%) were preventable. Significant decreases in the rate of harms per 1,000 patient-days (21.8 vs 27.1, relative risk (RR) = 0.77, 95% CI 0.66-0.91, P = .02) and in high-severity events (categories F to I) (11/720 clinical records in 2011-2012 vs 23/720 clinical records in 2007-2009) (RR = 0.48, 95% CI = 0.24-0.96, P = .04) were observed during the second half of the study from the first. The number needed to alert was 7.8.

CONCLUSION:

The frequency and severity of AEs decreased during the period of study. Factors possibly contributing to the decrease in AEs include new beds with variable height, pressure ulcer prevention, introduction of clinical electronic records, staff training on hand washing, surgical check list, correct patient identification, and Agency for Healthcare Research and Quality surveys on patient safety culture.
