Abstract
BackgroundPrescribing an antibiotic is a complex process involving an interplay of prescriber’s knowledge, diagnostic acumen and patient factors. Understanding the prescriber rationale is key to provide feedback which might improve appropriateness of antibiotic prescribing. Currently, there are limited data on prescribing and test ordering practices among primary care physicians.MethodsWe surveyed primary care physicians taking care of adults (age 18 years and above). Physicians were contacted through the Idaho State Medical Board by a one-time email containing the survey link. The survey consisted of 25 questions under 2 major themes of diagnostic and antimicrobial stewardship (AS). It assessed physicians’ practice setting, ordering of diagnostic tests and antibiotics for common infections, delivery of patient education regarding antibiotics, availability of antibiogram and antimicrobial stewardship services, and assessment of penicillin allergy. Two infectious diseases physicians independently reviewed the results for appropriateness of testing and antibiotic prescribing per IDSA guidelines.ResultsOf 929 physicians surveyed, 157 (17%) responded. Of the respondents, 95 (61%) were male, the mean age was 50 years, and 72% worked in outpatient settings and were family medicine specialists. Only 55% of physicians reported having an AS program at their healthcare facility. Test-of-cure for C. difficile infection (24%) and UTI (13%) and use of superficial culture data to guide the treatment of osteomyelitis (27%) were the most common reasons for inappropriate testing. Longer than recommended duration, antibiotic combinations with overlap of spectrum, and guideline-discordant indications for prescribing antibiotics were the main reasons for inappropriate antibiotic use. The main factors influencing the decision to prescribe an antibiotic were diagnostic uncertainty (42%), being unsure of patient follow-up (23%) and cost of testing (21%).ConclusionThe survey results highlight the need for prescriber education for decreasing inappropriate test ordering and antibiotic prescribing. Additional studies involving a review of patient records, lab and prescription data are needed to confirm these practices.Disclosures All authors: No reported disclosures.
