Objective:
A pilot study to evaluate a staff training intervention implementing a nurse-led hypertension care model.
Design And Setting:
Clinical and laboratory data from all primary care centres (PCCs) in the Swedish region Västra Götaland (VGR), retrieved from regional registers. Intervention started 2018 in 11 PCCs. A total of 190 PCCs served as controls. Change from baseline was assessed 2 years after start of intervention.
Intervention:
Training of selected personnel, primarily in drug choice, team-based care, measurement techniques, and use of standardized medical treatment protocols.
Patients:
Hypertensive patients without diabetes or ischemic heart disease were included. The intervention and control groups contained approximately 10,000 and 145,000 individuals, respectively.
Main Outcome Measures:
Blood pressure (BP) <140/90 mmHg, LDL-cholesterol (LDL-C) <3.0 mmol/L, BP ending on -0 mmHg (digit preference, an indirect sign of manual measuring technique), choice of antihypertensive drugs, cholesterol lowering therapy and attendance patterns were measured.
Results:
In the intervention group, the percentage of patients reaching the BP target did not change significantly, 56%-61% (control 50%-52%), non-significant. However, the percentage of patients with LDL-C < 3.0 mmol/L increased from 34%-40% (control 36%-36%), p = .043, and digit preference decreased, 39%-27% (control 41%-35%), p = 0.000. The number of antihypertensive drugs was constant, 1.63 - 1.64 (control 1.62 - 1.62), non-significant, but drug choice changed in line with recommendations.
Conclusion:
Although this primary care intervention based on staff training failed to improve BP control, it resulted in improved cardiovascular control by improved cholesterol lowering treatment.

Blood Pressure
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the...
Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
