Objectives: The UK Department of Health has made recommendations on safe and appropriate prescribing of anti-infectives. In response, we reviewed our anti-infective policies to ensure they were in line with best practice. As a result, a new adult anti-infective policy was launched. To help facilitate its implementation, a quality improvement programme was established, with the aim of achieving >90% compliance with the new policy.
Methods: Patients under the care of the medical admissions teams who had been prescribed one or more systemic anti-infectives between January and November 2008 were included in the study. Study pharmacists collected data daily on all patients, including the anti-infective(s) prescribed and indication(s) documented on either the patient's drug prescription chart or health records. A definition of compliance was developed, which required documented indication(s) and associated anti-infectives to match the anti-infective policy. A baseline compliance level was established; we then implemented a series of interventions using the plan-do-study-act ('PDSA') approach to monitor and improve compliance. Three overlapping intervention phases were retrospectively identified: raising awareness; education; and weekly feedback of results in the form of run charts distributed to medical teams.
Results: Over the 11 month study period, compliance with the policy increased from 30% to 71%. Since 2008, we have seen the average compliance increase year-on-year to over 90% in 2010 using a sustainable once weekly data collection model.
Conclusions: This study shows that it is possible to use quality improvement methodology to support antimicrobial stewardship within existing resources and suggests that an improvement in policy compliance can be both achieved and sustained.
