1459. Patient-provider communication as a key factor in preventing health care–associated infections in hospitalized patients
Poster Abstract Session: HAI: Surgical Site Infections
Friday, October 28, 2016
Room: Poster Hall
Background: Elderly and minority patients have significantly higher rates of health care-associated infections (HAIs). For surgical patients in particular, the HAI risk increases dramatically with increasing age. The impact of hospital characteristics on HAIs for this population, however, has not been widely researched. Methods: Using the Agency for Healthcare Research and Quality’s (AHRQ) Medicare Patient Safety Monitoring System (MPSMS), patient characteristics were identified for data from 2010 – 2013. The MPSMS data were linked to the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) data to add patient-reported hospital performance as an independent variable. The American Hospital Association annual survey data were used to investigate hospital characteristics. A stepwise regression model test was used to select hospital characteristics for association with HAIs while controlling for patient characteristics. There were 109,974 MPSMS patient records for the study period, of which 2% had an HAI. Results:Stratifying per condition, elderly surgical patients aged 65 and older had dramatically higher rates of HAIs compared to those between the ages of 18-64, with a significant difference in 85+ versus 18-64 years (odds ratio: 4.81). Hospital characteristics were also found to have significant effects on the risk of HAIs. A 34% reduction in the odds of HAI was associated with surgical patients in hospitals with a 10 percentage point higher HCAHPS measure of “communication about medicines.” Patients had fewer HAIs when treated in hospitals with favorable ratings for HCAHPS measures of patient-provider communication.
This finding suggests that health care professionals, who offer patient-centered, team-based care, with caregivers functioning and communicating effectively with patients, achieve better outcomes and have fewer HAIs.
