Visit patterns at primary care centres and individual blood pressure level – a cross-sectional study

Abstract Objective: Hypertension is a major cause of cardiovascular disease. Nevertheless, blood pressure (BP) is often inadequately treated. We studied visit patterns at primary health care centres (PHCCs) and their relation to individual BP control. Design and setting: Cross-sectional register-based study on all patients with hypertension who visited 188 PHCCs in a Swedish region. Patients: A total of 88,945 patients with uncomplicated hypertension age 40–79. Main outcome measures: Odds ratio (OR) for the individual patient to achieve the BP target of ≤140/90？mmHg. Results: Overall, 63% of patients had BP？≤？140/90？mmHg (48% BP？<？140/90). The PHCC that the patient was enrolled at and, as part of that, more nurse visits at PHCC level was associated with BP control, adjusted OR 1,10 (95% CI 1.01 to 1.21). Patients visiting PHCCs with the highest proportion of visits with nurses had an even higher chance of achieving the BP target, OR 1.19 (95% CI 1.07 to 1.32). Conclusions: In a Swedish population of patients with hypertension, about half do not achieve recommended treatment goals. Organisation of PHCC and team care are known as factors influencing BP control. Our results suggests that a larger focus on PHCC organisation including nurse based care could improve hypertension care
