Professionals' awareness of operational antibiotic prescribing controls in UK NHS hospitals

Qualitative study of factors associated with antimicrobial usage in seven small animal veterinary practices in the UK

Responsible use of antimicrobials by veterinarians is essential to contain antimicrobial resistance in pathogens relevant to public health. Inappropriate antimicrobial use has been previously described in practice. However, there is scarce information on factors influencing antimicrobial usage in dogs and cats. We investigated intrinsic and extrinsic factors influencing decision-making of antimicrobial usage in first opinion small animal practices in the UK through the application of qualitative research methods. Semi-structured interviews were conducted with 21 veterinarians from seven veterinary first opinion practices in the UK in 2010. Topics investigated included: a) criteria used for selection of antimicrobials, b) influences by colleagues, c) influences by clients, d) pet characteristics, e) sources of knowledge, f) awareness of guidelines and g) protocols implemented in practice that may affect antimicrobial usage by veterinarians. Hypothetical scenarios selected to assess appropriateness of antimicrobial usage were: a) vomiting in a Yorkshire Terrier due to dietary indiscretion, b) deep pyoderma in a Shar-Pei, c) Feline Lower Urinary Tract disease in an 7 year-old male neutered cat and d) neutering of a 6-months dog. Interviews were recorded and transcribed by the interviewer. Thematic analysis was used to analyse content of transcribed interviews. Data management and analysis was conducted with qualitative analysis software NVivo8 (QSR International Pty Ltd). Antimicrobial usage by participants was influenced by factors other than clinical evidence and scientific knowledge. Intrinsic factors included veterinarian's preference of substances and previous experience. Extrinsic factors influencing antimicrobial selection were; perceived efficacy, ease of administration of formulations, perceived compliance, willingness and ability to treat by pet owners, and animal characteristics. Cost of therapy was only perceived as an influential factor in low, mixed socioeconomic areas. Veterinarians had limited awareness of current recommendations for responsible use in small animal practice. Social norms, particularly verbally agreed protocols influenced veterinarians. Inappropriate antimicrobial usage was identified in the therapy of non-infectious diseases and prophylaxis of routine clean surgical procedures. Discussion of clinical cases with peers and effectiveness meetings in the workplace were useful to veterinarians to share scientific knowledge. Effectiveness meetings can be a common ground for veterinarians to discuss and agree protocols for clinical conditions and surgical procedures. Protocols should be evidence-based, follow current recommendations and take into account the resources available in the workplace. Targeted training of veterinarians in the workplace with peer support should be used to promote responsible antimicrobial usage.

Rationing and deprivation: disease-modifying therapies for multiple sclerosis in the United Kingdom

Unlike other industrialised countries, the UK deferred the routine introduction of disease-modifying therapies (DMTs) for multiple sclerosis (MS) in favour of an experiment. Between 2002 and 2005, MS sufferers were identified, were offered DMTs only if deemed suitable by their physicians, and were monitored thereafter to assess long-term outcomes. It has been demonstrated for other therapies that judgements about suitability to receive treatment are conditioned by the patient's deprivation status. We hypothesised that this would have been the case for DMTs also. Using individual patient data for samples in Nottingham and in Glasgow, we matched patients' postcodes of residence with deprivation scores and confirmed that patients from more deprived areas were less likely to have been prescribed DMTs. A more detailed analysis of the Nottingham data revealed two channels through which this outcome was effected. First, people from less-deprived areas were more likely to possess clinical characteristics, such as less severe disease severity and shorter duration of the disease, that enhanced their suitability for treatment. Second, the analysis of the clinical notes detailing patients' correspondence with the medical teams suggested that less-deprived people were more able to exercise a voice capable of influencing physicians' prescribing decisions.

Impact of the Hospital Pharmacy Initiative for promoting prudent use of antibiotics in hospitals in England

OBJECTIVES

In July 2003, the UK Department of Health announced an allocation of 12 million pounds sterling to hospital pharmacists to improve the monitoring and control of anti-infective use over the ensuing 3 year period (the Hospital Pharmacy Initiative, or HPI). Chief Pharmacists were asked to use this money for developments to promote prudent antibiotic use and monitoring of antimicrobials within their Trusts. This study aimed to evaluate the impact of the HPI funding, which at the time had been in place for nearly 2 years, on pharmacy activities in this area.

METHODS

A postal questionnaire was sent to the pharmacy department of each acute hospital Trust in England, aiming to provide a descriptive overview of the activities of hospital pharmacy staff in the field of anti-infectives and to explore the extent to which these activities were made possible by the HPI funding.

RESULTS

One hundred and forty-one specialist antimicrobial pharmacy staff were employed in 130 responding Trusts; 89% were pharmacists, 7% pharmacy technicians and the remainder administrative staff. Three-quarters of these staff had been employed due to the funding, resulting in review of antimicrobial prescribing guidelines, antibiotic audit projects and multidisciplinary work with Microbiology/Infectious Diseases staff. Thirteen Trusts gave details of drug acquisition cost savings; over the course of a year, these Trusts saved 1.1 million pounds sterling in total.

CONCLUSIONS

The HPI funding has facilitated greater interaction between Pharmacy and Microbiology/Infectious Diseases departments than was previously possible. Significant reductions in antibiotic acquisition costs have been demonstrated, though further work is warranted to fully establish the impact of pharmacy activities on clinical and microbiological outcomes.
