The feasibility and effectiveness of emergency department based hypertension screening: a systematic review

Abstract

Purpose: Hypertension is a highly prevalent risk factor for cardiovascular disease, and its early identification and management results in reductions in morbidity and mortality. Our objectives were to: (1) determine the extent to which the emergency department (ED) has been used to screen patients for undiagnosed hypertension; (2) estimate the incidence of undiagnosed hypertension in the ED population; (3) identify and describe the programs for ED hypertension screening; and (4) determine the feasibility of ED-based hypertension screening programs and the requirements for further study.

Data sources: An online search of databases (i.e., OVID Search, CINAHL, Scopus, Web of Science), unpublished sources (i.e., ProQuest Dissertation & Theses and Papers First), and grey literature (i.e., OpenSIGLE and the New York Academy of Grey Literature) was conducted. A manual search of the reference lists of relevant studies was also completed.

Conclusion: Hypertension screening in the ED is feasible. Individuals with elevated blood pressure (BP) in the ED should be referred for follow-up. Further study is needed to develop an ED screening tool that is predictive of persistently elevated BP in undiagnosed individuals.

Implications for practice: Nurse practitioners in the ED should identify patients with elevated BP, provide hypertension education, and ensure appropriate intervention and referral.
