To examine how individual steward characteristics (eg, steward role, sex, and specialized training) are associated with their views of antimicrobial stewardship program (ASP) implementation at their institution.
Descriptive survey from a mixed-methods study.
Two large national healthcare systems; the Veterans’ Health Administration (VA) (n = 134 hospitals) and Intermountain Healthcare (IHC; n = 20 hospitals).
We sent the survey to 329 antibiotic stewards serving in 154 hospitals; 152 were physicians and 177 were pharmacists. In total, 118 pharmacists and 64 physicians from 126 hospitals responded.
The survey was grounded in constructs of the Consolidated Framework for Implementation Research, and it assessed stewards’ views on the development and implementation of antibiotic stewardship programs (ASPs) at their institutions We then examined differences in stewards’ views by demographic factors.
Regardless of individual factors, stewards agreed that the ASP added value to their institution and was advantageous to patient care. Stewards also reported high levels of collegiality and self-efficacy. Stewards who had specialized training or those volunteered for the role were less likely to think that the ASP was implemented due to a mandate. Similarly volunteers and those with specialized training felt that they had authority in the antibiotic decisions made in their facility.
Given the importance of ASPs, it may be beneficial for healthcare institutions to recruit and train individuals with a true interest in stewardship.
To examine inappropriate antibiotic prescribing for acute respiratory tract infections (RTIs) in ambulatory care to help target antimicrobial stewardship interventions.
Design and Setting
Retrospective analysis of RTI visits within general internal medicine (GIM) and family medicine (FM) ambulatory practices at an inner-city academic medical center from 2008 to 2010.
Patient, physician, and practice characteristics were analyzed using multivariable logistic regression to determine factors predictive of inappropriate prescribing; physicians in the highest and lowest antibiotic-prescribing quartiles were compared using χ2 analysis.
Visits with FM providers, female gender, and self-reported race/ethnicity as white or Hispanic were significantly associated with inappropriate antibiotic prescribing. Physicians in the lowest quartile prescribed antibiotics for 5%–28% (mean, 21%) of RTI visits; physicians in the highest quartile prescribed antibiotics for 54%–85% (mean, 65%) of RTI visits. High prescribers had fewer African-American patients and more patients who were younger and privately insured. High prescribers had more patients with chronic lung disease. A GIM practice pod with a low prescriber was 3.0 times more likely to have a second low prescriber than other practice pods, whereas pods with a high prescriber were 1.3 times more likely to have a second high prescriber.
Medical specialty was the only physician factor predictive of inappropriate prescribing when patient gender, race, and comorbidities were taken into account. Possible disparities in care need further study. Stewardship education in medical school, enlisting low prescribers as physician leaders, and targeting interventions to the highest prescribers might be more effective approaches to antimicrobial stewardship.
