To determine whether the gender of clinicians making antimicrobial stewardship recommendations has an impact on intervention acceptance rate.

A retrospective, multivariable analysis of antimicrobial stewardship prospective audit and feedback outcomes.

A multisite healthcare system including Mayo Clinic Rochester (MN), Mayo Clinic Arizona, Mayo Clinic Florida and 17 health-system hospital sites, where prospective audit and feedback is performed and documented within an electronic tool embedded in the medical record.

The study included 143 Mayo Clinic clinicians (84 cisfemales and 59 cismales).

Outcomes were analyzed from July 1, 2017, to June 30, 2022, for intervention rates, communication methods, and intervention acceptance by clinician gender, profession, patient age, and intensive care unit (ICU) status of patient.

Of 81,927 rules, 71,729 rules met study inclusion. There were 18,175 (25%) rules associated with an intervention. Most of the rules were reviewed by pharmacists (86.2%) and stewardship staff (85.5%). Of 10,363 interventions with an outcome documented, 8,829 (85.2%) were accepted and 1,534 (14.8%) were rejected. Female clinicians had 6,782 (86.5%) of 7,843 interventions accepted, and male clinicians had 2,047 (81.2%) of 2,520 interventions accepted (P = .19). Female patients had more interventions than male patients (female vs male: 25.9% vs 24.9%; OR, 1.04; 95% CI, 1.02–1.08; P = .001). Patients in the ICU had a significantly lower intervention acceptance rate (ICU vs non-ICU: 78.2% vs 86.7%; OR, 0.56; 95% CI, 0.45–0.7; P < .001).

Female and male clinicians were equally effective at prospective audit and feedback in a multisite antimicrobial stewardship program. Patients in the ICU were less likely to have stewardship interventions accepted.

To investigate differences in the rate of firstline antibiotic prescribing for common pediatric infections in relation to different socioeconomic statuses and the impact of an antimicrobial stewardship program (ASP) in pediatric urgent-care clinics (PUCs).

Quasi-experimental.

Three PUCs within a Midwestern pediatric academic center.

Patients aged >60 days and <18 years with acute otitis media, group A streptococcal pharyngitis, community-acquired pneumonia, urinary tract infection, or skin and soft-tissue infections who received systemic antibiotics between July 2017 and December 2020. We excluded patients who were transferred, admitted, or had a concomitant diagnosis requiring systemic antibiotics.

We used national guidelines to determine the appropriateness of antibiotic choice in 2 periods: prior to (July 2017–July 2018) and following ASP implementation (August 2018–December 2020). We used multivariable regression analysis to determine the odds ratios of appropriate firstline agent by age, sex, race and ethnicity, language, and insurance type.

The study included 34,603 encounters. Prior to ASP implementation in August 2018, female patients, Black non-Hispanic children, those >2 years of age, and those who self-paid had higher odds of receiving recommended firstline antibiotics for all diagnoses compared to male patients, children of other races and ethnicities, other ages, and other insurance types, respectively. Although improvements in prescribing occurred after implementation of our ASP, the difference within the socioeconomic subsets persisted.

We observed socioeconomic differences in firstline antibiotic prescribing for common pediatric infections in the PUCs setting despite implementation of an ASP. Antimicrobial stewardship leaders should consider drivers of these differences when developing improvement initiatives.
