Contribution of Final-Year Medical Students to Hypertension Diagnosis in Primary Care Units.

BACKGROUND/

objectiveWorldwide, ~45% of hypertensives remain undiagnosed, and ~26% are adequately controlled. The active involvement of all healthcare professionals in diagnosing hypertension at primary health care units (PHCUs) is linked to better blood pressure (BP) control. There is currently no research examining the potential role of senior medical students in the diagnosis of hypertension. This study aimed to evaluate the contribution of final-year medical students' active participation in the diagnosis of hypertension. The study also examined the prevalence and control of hypertension among health service users in Greek PHCUs.

methodsThis is a cross-sectional convenience sample study. During clinical placement in PHC, sixth-year medical students received systematic training and performed BP measurements, according to the guidelines, in private, well-organized spaces. Adult patients and visitors were enlisted for BP measurements. The BP readings were provided to the participants so they could discuss any concerns about their BP with their physician. Statistical analysis was performed with SPSS. Categorical variables are presented as frequencies. Continuous variables were assessed for normality and, based on their distribution, are expressed as mean ± standard deviation or median (interquartile range). Appropriate tests were performed for the comparisons across groups (chi-square for the categorical variables, and two-sample

resultsIn the present study, 124 medical students performed BP measurements in 68 PHCUs. BP was measured in 704 individuals, aged 61 (IQR: 48.0-73.0) years old; 58.8% were female, 68.3% of whom were patients. The prevalence of hypertension was 56.7%. The control rate was 44.9% (BP < 140 and 90 mmHg among all hypertensives), and the control rate under treatment was 61.0% (BP < 140 and 90 mmHg among treated hypertensives). The involvement of medical students contributed positively, increasing the diagnosis of hypertension in individuals who might not have their BP measured in routine clinical practice. Ninety-nine newly diagnosed hypertensives were detected. Students identified 220 uncontrolled hypertensives and 112 uncontrolled under-treated patients, who were then referred to the consultant physicians.

conclusionsStudents played a critical role in diagnosing hypertension and identifying newly diagnosed hypertensive patients. Embracing interprofessional care in the diagnosis and management of hypertension is essential for achieving better outcomes for our patients. Engaging medical students in BP measurements is a practical and feasible approach to improve hypertension diagnosis and control, taking into consideration the increased workload of PHC physicians. While this action has important medical education implications, the impact on the knowledge level of medical students was not evaluated. Limitations of this study include the assessment of BP in one visit without home BP measurements or a second visit, lack of follow-up of newly diagnosed hypertensives, and the low average number of BP measurements per student.
