Abstract
Abstract Background To reduce antibiotic prescribing, antimicrobial stewards must understand patient knowledge, attitudes, and perceptions (KAP) around antibiotics for URIs. Validated patient KAP surveys are scarce and for Veteran patients, nonexistent. We aimed to explore if published results of an exploratory factor analysis (EFA) of a KAP survey in emergency department (ED) patients and an online sample would approximate results in outpatient Veterans. Methods After cognitive testing in Veterans and healthcare providers, we omitted 13 of the 46 questions from the published KAP survey deemed confusing or with low factor loadings. We mailed the 33-item survey to Veterans seen for URI at 18 Veterans Affairs clinics from January 2018 to December 2019. We excluded Veterans not evaluated in-person, with documented dementia, or who died prior to study start. We excluded surveys with > 3 unanswered questions. We used principal component factor analysis (PCFA) with orthogonal varimax rotation (Fig. 1) to assess Veteran responses and Cronbach’s alpha to assess each factor’s internal consistency. We removed questions to reach alpha of >0.7 (Fig. 2). We repeated PCFA and compared results to published EFA factors and loadings for the ED patients and online sample. Results Of 1329 eligible Veterans invited, 474 (36%) returned the survey; 407 met inclusion criteria (Table 1). PCFA of Veterans’ responses yielded 7 Factors (Fig 2). Like ED patients and the online sample, Veteran responses about side effects clustered together. Veteran responses about “antibiotics help” and “antibiotics don’t hurt” clustered together like ED patients. They grouped separately in the online sample. Veteran responses about safety and efficacy (Factors 3 & 5) and knowledge about viruses and bacteria, (Factors 4 & 5) clustered separately (Fig. 2). For ED patients and the online sample, safety and efficacy and virus and bacteria responses clustered together, respectively (Fig. 1). Conclusion While Veterans did share some KAPs around antibiotics for URIs with ED patients and the online sample, this study shows they also have distinct views. Further testing in Veteran and non-Veteran populations should validate and assess reliability of this survey as an antimicrobial stewardship tool. Disclosures Carlos G.
