Nurse visit utilization and blood pressure control: A multi-cohort study in New Zealand

Objective: This study aimed to retrospectively examine the contribution of nurses to population health outcomes with reference to nurse visits and blood pressure measurement in primary health settings. Design: A retrospective study was conducted using New Zealand Health Survey (NZHS) from 2012 to 2017. Sample: Adult population who are 18 years old and over living in New Zealand. Measurements: Age, gender, and ethnicity, the service utilization of primary health care nurse visit and blood pressure measurement were extracted from the NZHS (2012–2017) to compare with the service utilization of primary health care nurses by different demographic groups. Results: Females who have treated hypertension shows higher utilization of nurse visit than males. From 2015 to 2017, the participants in this cohort have visited a primary health care nurse at least more than once within a year. With blood pressure control, the overall pooled results show the impact of visiting primary health nurses on systolic and diastolic blood pressure control. Conclusion: Our study at a national scale, demonstrated the impact of nurse's contribution to population health outcomes among people living with hypertension in New Zealand. Nurses are key to improving population health outcomes and to achieve universal health coverage.
