Burnout Linked to Hospital Infections
Researchers studied the effect of
nurse staffing and burnout on
catheter-associated urinary tract
Researchers analyzed data previously collected by the Pennsylvania Health Care Cost Containment Council, the American Hospital Association Annual Survey, and a 2006 survey of more than 7,000 registered nurses from 161 hospitals in Pennsylvania to study the effect of nurse staffing and burnout on catheter-associated urinary tract infections (CAUTI) and surgical site infections (SSI), two of the most common HAIs.
Job-related burnout was determined by analyzing the emotional exhaustion subscale from the Maslach Burnout Inventory-Human Services Survey (MBI-HSS) that was obtained from nurse survey responses. The MBI-HSS filters 22 items on job-related attitudes into emotional exhaustion, depersonalization, and personal accomplishment, identifying emotional exhaustion as the key component to burnout syndrome. More than one-third of survey respondents got an emotional exhaustion score of 27 or greater, the MBI-HSS definition for healthcare personnel burnout.
Comparing CAUTI rates with nurses' patient loads (5.7 patients on average), the researchers found that for each additional patient assigned to a nurse, there was roughly one additional infection per 1,000 patients (or 1,351 additional infections per year, calculated across the survey population). Additionally, each 10 per cent increase in a hospital's high-burnout nurses corresponded with nearly one additional CAUTI and two additional SSIs per 1,000 patients annually (average rate of CAUTIs across hospitals was 9 per 1,000 patients; for SSIs it was 5 per 1,000 patients).
Using the per-patient average costs associated with CAUTIs (749 to 832 Dollars each) and SSIs (11,087 to 29,443 Dollars each), the researchers estimate that if nurse burnout rates could be reduced to 10 per cent from an average of 30 per cent, Pennsylvania hospitals could prevent an estimated 4,160 infections annually with an associated savings of 41 million Dollars.
