ABSTRACT
OBJECTIVES: To assess the effect of a point of care (POC) device for testing lipids and HbA1c in addition to testing by community laboratory facilities (usual practice) on the completion of cardiovascular disease (CVD) risk assessments in general practice. METHODS: We conducted a pragmatic, cluster randomised controlled trial in 20 New Zealand general practices stratified by size and rurality and randomised to POC device plus usual practice or usual practice alone (controls). Patients aged 35-79 years were eligible if they met national guideline criteria for CVD risk assessment. Data on CVD risk assessments were aggregated using a web-based decision support programme common to each practice. Data entered into the on-line CVD risk assessment form could be saved pending blood test results. The primary outcome was the proportion of completed CVD risk assessments. Qualitative data on practice processes for CVD risk assessment and feasibility of POC testing were collected at the end of the study by interviews and questionnaire. The POC testing was supported by a comprehensive quality assurance programme. RESULTS: A CVD risk assessment entry was recorded for 7421 patients in 10 POC practices and 6217 patients in 10 control practices; 99.5% of CVD risk assessments had complete data in both groups (adjusted odds ratio 1.02 [95%CI 0.61-1.69]). There were major external influences that affected the trial: including a national performance target for CVD risk assessment and changes to CVD guidelines. All practices had invested in systems and dedicated staff time to identify and follow up patients to completion. However, the POC device was viewed by most as an additional tool rather than as an opportunity to review practice work flow and leverage the immediate test results for patient education and CVD risk management discussions. Shortly after commencement, the trial was halted due to a change in the HbA1c test assay performance. The trial restarted after the manufacturing issue was rectified but this affected the end use of the device. CONCLUSIONS: Performance incentives and external influences were more powerful modifiers of practice behaviours than the POC device in relation to CVD risk assessment completion. The promise of combining risk assessment, communication and management within one consultation was not realised. With shifts in policy focus, the utility of POC devices for patient engagement in CVD preventive care may be demonstrated if fully integrated into the clinical setting.

Despite anecdotes of many chronic care management and integrated care projects around New Zealand, there is no formal process to collect and share relevant learning within (but especially between) District Health Boards (DHBs). We wish to share our experiences and hope to stimulate a productive exchange of ongoing learning. We define chronic care management and integrated care, then summarise current theory and evidence. We describe national policy development (relevant to integrated care, since 2000) including the New Zealand Health Strategy, the NZ Primary Care Strategy, the development of Primary Health Organisations (PHOs), capitation payments, Care Plus, and Services to Improve Access funding. We then describe chronic care management in Counties Manukau, which evolved both prior to and during the international refinement of theory and evidence and the national policy development and implementation. We reflect on local progress to date and opportunities for (and barriers to) future improvements, aided by comparative reflections on the United Kingdom (UK). Our most important messages are addressed as follows: To policymakers and funders--a fragile culture change towards teamwork in the health system is taking place in New Zealand; this change needs to be specifically and actively supported. To PHOs--general practices need help to align their internal (within-practice) financial signals with the new world of capitation and integrated care. To primary and secondary care doctors, nurses, and other carers - systematic chronic care management and integrated care can improve patient quality of life; and if healthcare structures and systems are properly managed to support integration, then healthcare provider professional and personal satisfaction will improve.
