Understanding Compliance to an Antibiotic Prescribing Policy: Perspectives of Policymakers and Prescribers

Abstract

Background Antibiotic stewardship programs have been shown to reduce inappropriate institutional antibiotic use. There is no consensus on the strategies, e.g. formulary restrictions, that best improve appropriate use and reduce misuse of antibiotics. Aim To identify facilitators and barriers to compliance with an institutional antibiotic prescribing policy and to compare policymakers' perceptions about the facilitators and barriers that influence compliance with those held by prescribers. Method 5 antimicrobial stewardship committee members (policymakers) and 15 prescribers from a large Sydney hospital participated in a semi‐structured interview. To gauge prescribers' knowledge of the institutional antibiotic policy, case scenarios were included in the interviews with prescribers. Interviews were continued until data saturation was reached. Recurrent themes were analysed and interpreted in terms of a well‐known conceptual framework of barriers to physician adherence to guidelines. Results Antimicrobial stewardship committee members identified lack of knowledge as the main barrier to compliance with the antibiotic prescribing policy. Despite reporting that they were aware of and agreed with the antibiotic prescribing policy, most prescribers did not comply with the policy and referred to clinical information sources when completing the case scenarios. Organisational hierarchies were frequently reported as a barrier by both participant groups. While prescribers considered inapplicability of the antibiotic prescribing policy as an important barrier, antimicrobial stewardship committee members attributed non‐compliance to the policy to prescriber autonomy and personal experience. Conclusion We identified several barriers to compliance with the antibiotic prescribing policy, such as poor knowledge of policy specifics and medical hierarchies. Involving prescribers in policy development, giving them feedback about their prescribing, and improving existing collaboration and decision support platforms may further improve judicious antibiotic use.

Use of theory to plan or evaluate guideline implementation among physicians: a scoping review

“…Several studies used models (6, 14.3%) or frameworks (4, 9.5%). Models or frameworks used more than once included the Cabana Framework of Barriers to Physician Guideline Adherence [ 44 , 52 , 56 ] and the Attitude Social Norm Self Efficacy model [ 43 , 53 ]. Some studies used a combination of two or more theories, models, or frameworks [ 40 , 55 , 60 ], two of which used one or both of the TPB or TDF [ 40 , 55 ].…”

Education to improve vancomycin use: the perspectives of educators and education recipients

“…Qualitative studies with prescribers of vancomycin have shown that poor knowledge of hospital antibiotic guidelines is a key reason for inappropriate antibiotic use . While providing vancomycin‐specific education to health professionals is likely to improve vancomycin dosing and TDM practices, there is limited evidence available to guide the design and implementation of effective education strategies.…”

A realist analysis of hospital patient safety in Wales: applied learning for alternative contexts from a multisite case study

“…57,671 Collectively, their active stewardship of antibiotic prescribing is acknowledged to limit overprescribing 672 and improve adherence to guidelines. [673][674][675][676] However, their oversight of surgical prophylaxis is constrained by the charting and timing of the administration of such drugs within the theatre environment. [677][678][679] There are many other ways in which patients may acquire infections while in hospital.…”
