The feasibility and generalizability of assessing the appropriateness of antimicrobial prescribing in hospitals: a review of the Australian National Antimicrobial Prescribing Survey.

The National Antimicrobial Prescribing Survey (NAPS) is a web-based qualitative auditing platform that provides a standardized and validated tool to assist hospitals in assessing the appropriateness of antimicrobial prescribing practices. Since its release in 2013, the NAPS has been adopted by all hospital types within Australia, including public and private facilities, and supports them in meeting the national standards for accreditation. Hospitals can generate real-time reports to assist with local antimicrobial stewardship (AMS) activities and interventions. De-identified aggregate data from the NAPS are also submitted to the Antimicrobial Use and Resistance in Australia surveillance system, for national reporting purposes, and to strengthen national AMS strategies. With the successful implementation of the programme within Australia, the NAPS has now been adopted by countries with both well-resourced and resource-limited healthcare systems. We provide here a narrative review describing the experience of users utilizing the NAPS programme in Canada, Malaysia and Bhutan. We highlight the key barriers and facilitators to implementation and demonstrate that the NAPS methodology is feasible, generalizable and translatable to various settings and able to assist in initiatives to optimize the use of antimicrobials.

Topical antimicrobial prescribing patterns in residents of Australian aged-care facilities: use of a national point prevalence survey to identify opportunities for quality improvement.

BACKGROUND: Australian residential aged care facilities (RACFs) are encouraged to participate in an annual Aged Care National Antimicrobial Prescribing Survey. This data source was analysed to describe patterns of topical antimicrobial prescribing and thereby provide insight into antimicrobial stewardship (AMS) changes that might be required. METHODS: 2018 and 2019 survey data was analysed. RESULTS: The overall prevalence of the 52,431 audited residents (629 facilities) who were prescribed 1 or more topical antimicrobials was 2.9%. Of all prescribed antimicrobials (n=4899), 33.0% were for topical application. Most frequently prescribed topical antifungals were clotrimazole (85.3%) and miconazole (9.1%), and antibacterials chloramphenicol (64.1%) and mupirocin (21.8%). Tinea (38.3%) and conjunctivitis (23.8%) were the 2 most common indications. Topical antimicrobials were sometimes prescribed for pro re nata administration (38.8%) and greater than 6 months (11.3%). The review or stop date was not always documented (38.7%). CONCLUSIONS: To reduce the possibility of adverse consequences associated with antimicrobial use, antimicrobial stewardship programs in Australian residential aged care facilities should at least ensure mupirocin is appropriately used, first line antimicrobial therapy is prescribed for tinea, chloramphenicol is prescribed for conjunctivitis only if necessary, pro re nata orders for prescriptions are discouraged and to avoid prolonged duration of prescriptions, review or stop dates are always documented.

Measuring antimicrobial prescribing quality in outpatient parenteral antimicrobial therapy (OPAT) services: development and evaluation of a dedicated national antimicrobial prescribing survey.

BACKGROUND: Antimicrobial stewardship programmes are important in driving safety and quality of antimicrobial prescribing. The National Antimicrobial Prescribing Survey (NAPS) is a point-prevalence audit of inpatient antimicrobial prescribing in Australian hospitals. OBJECTIVES: To design and adapt the NAPS tool for use in the outpatient parenteral antimicrobial therapy (OPAT) and hospital-in-the-home (HITH) setting. METHODS: An inter-disciplinary working group with expertise in OPAT and HITH services was established to adapt the NAPS template for use in the OPAT setting-called HITH-NAPS. This was initially trialled in 5 HITH services, subsequently adapted following participant feedback, then offered nationally to 50 services in 2017. RESULTS: There were 1154 prescriptions for 715 patients audited via the HITH-NAPS. The most common antimicrobials prescribed were cefazolin (22%), flucloxacillin (12%), piperacillin/tazobactam (10%) and ceftriaxone (10%). The most common infections treated were cellulitis (30%) and respiratory tract infections (14%). Eighty-seven percent of prescriptions were assessed as appropriate, 11% inappropriate and 2% not assessable. Prolonged durations of antimicrobials and unnecessarily broad-spectrum antibiotics were used in 9% of prescriptions. CONCLUSIONS: The HITH-NAPS pilot project revealed that auditing of this type is feasible in HITH. It showed that antibiotic use in these HITH services was generally appropriate, but there are some areas for improvement. A national OPAT/HITH-NAPS can facilitate benchmarking between services, identify potentially inappropriate prescribing and help guide quality improvement.
