Prescribing Data in General Practice Demonstration (PDGPD) project

The PDGPD project is a quality improvement activity for general practitioners (GPs).  The project has been developed by NPS in conjunction with the Australian General Practice Network (AGPN).

The quality improvement intervention gathered feedback on GPs’ prescribing for hypertension and chronic heart failure and used this feedback as a basis for discussions with practice peers and a trained facilitator in order to improve management of people with these conditions. The feedback was in the form of clinical indicator results (such as the percentage of chronic heart failure patients being prescribed a certain treatment when managed by a GP) and was generated by a data extraction software tool widely used by general practices. 

Aim

The aim of the PDGPD project is to determine whether a multifaceted intervention leads to improved prescribing practice and short-term clinical outcomes for patients with hypertension or chronic heart failure. The project will also assess whether the intervention is acceptable and sustainable in general practice. 

Design and methods

The impact on prescribing practice and short-term clinical outcomes (blood pressure control) was evaluated using a pragmatic cluster randomised controlled trial of the project surveys, interviews and focus groups with GPs and other practice staff provided subjective information about the perceived impact of the project on practices and patients.

The project’s acceptability and sustainability were assessed using a survey and focus groups with GPs, interviews and focus groups with project facilitators and interviews with other practice staff. GP feedback and evaluation forms provided additional information on GP acceptance and adoption of the quality improvement activities. 

Collaborators

The intervention was implemented by NPS in collaboration with the AGPN. 

The evaluation is being conducted by the Research & Development team at NPS with the support and advice of the PDGPD study guidance group:

  • Professor Jane Gunn (Professor of Primary Care Research, University of Melbourne)
  • Professor Nigel Stocks (Head, Discipline of General Practice, University of Adelaide)
  • Professor Jon Emery (Head of School and Chair, Department of General Practice, University of Western Australia.

Current status / summary of results

Data collection is complete and analysis and reporting is underway.

Informing practice 

The results from this research are being used to inform other quality improvement programs using data extraction from clinical software.
