Key result
Only ~61% of community pharmacies use validated blood pressure monitors, with rare routine calibration.
Why the study?
The study was conducted to assess the accuracy of digital blood pressure monitors used in English community pharmacies, as well as the overall quality, prevalence, and utilisation of pharmacy blood pressure services.
Cross-Sectional (n=109)
Yes
While community pharmacies in England provide valuable blood pressure screening services, particularly in deprived areas, significant quality enhancements are needed regarding device validation, calibration, and cuff sizes.
Pharmacy BP screening requires device validation and calibration checks before clinical reliance; leaves open questions on service reliability and standardization needs.
OBJECTIVES: The primary objective was to assess the accuracy (calibration and validation status) of digital blood pressure (BP) monitors used within community pharmacy in England and the secondary objectives were to assess the overall quality of the BP service by assessing service prevalence, service utilisation and other in-service considerations. DESIGN: A cross-sectional survey. SETTING: Primary-care retail-pharmacies. PARTICIPANTS: 500 pharmacies that contribute to government dispensing-data were invited by post to complete the survey. Private contractors were excluded. INTERVENTIONS: We conducted a questionnaire survey with a follow-up (September 2018 to December 2018). RESULTS: 109 responses were received. 61% (n=66) of responding pharmacies provided a free BP check to their patients. 40 (61%) pharmacies used recommended validated clinical metres, 6 (9%) had failed validation and 20 (30%) provided too little information to enable us to determine their monitor's status. CONCLUSIONS: Responding pharmacies were able to provide useful BP monitoring services to their patients, though quality enhancements need to be implemented. Majority of pharmacies use validated BP monitors, however, there was a lack of range of cuff sizes, variation in replacement and calibration of monitors and apparent absence of such practice in a minority of pharmacies alongside variation in training standards. We noted higher frequency of BP screening in the most deprived postcodes.We recommend in-service redesign and delivery improvements, and suggest professional bodies and researchers work together to create clearer frameworks for front-line practitioners, creating appropriate incentives to facilitate this service redesign.Funders and policy setters should consider the value added to the National Health Service and other healthcare agencies of such screening by pharmacy providers both nationally and internationally. It has the potential to reduce complications of undiagnosed hypertension and the medicines burden that it creates. Future work should examine the impact of pharmacist-led BP screening on patients.

Barrett et al. (2019) conducted a cross-sectional in Community pharmacy blood pressure screening (n=109). Community pharmacy blood pressure screening services vs. Pharmacies without blood pressure screening services was evaluated on Accuracy (calibration and validation status) of digital blood pressure monitors used within community pharmacy. Among responding pharmacies that provided free blood pressure checks, 61% used recommended validated clinical meters, though only a minority routinely calibrated their devices.
