High blood pressure readings on in-store machines: a qualitative study of the perspective of pharmacy staff

OBJECTIVES: Emergency department (ED) visits for high blood pressure are on the rise. Yet the majority of these patients are discharged home after their ED evaluation, particularly those who present following an elevated reading on an in-store pharmacy machine. We aimed to gain insight on the practice and referral patterns of pharmacy staff who encounter a patient with an elevated in-store blood pressure (BP) reading. METHODS: We conducted a qualitative study using semi-structured interviews with pharmacy staff (pharmacists and pharmacy technicians/assistants) from California, United States and Ontario, Canada. Interview questions were designed to examine the practice and referral patterns of pharmacy staff for patients with elevated in-store BP readings. Standard descriptive content analysis techniques were used to analyze the data and to develop themes for current practice and referral patterns. RESULTS: Twenty-four interviews were completed: six with pharmacy technicians/assistants and 18 with pharmacists. Canadian pharmacy staff (83%) reported being approached frequently (defined as from weekly up to multiple times per day) by patients concerned about an elevated BP reading on an in-store machine, versus 50% reported by American participants. Participant definition of an elevated BP varied, with systolic values ranging from 120 to 150 mmHg and diastolic values from 60 to 90 mmHg. Participants emphasized the need to converse with and assess their patients prior to providing advice. The most frequently reported advice was to seek referral from an outside health care provider: ED, urgent care, or a primary care practitioner. Severity of the BP reading and symptomatology were reported as determining factors for referring patients to the ED. Pharmacists (92%) reported a lack of corporate and/or governing body policy for managing patients with in-store markedly elevated BP readings. CONCLUSIONS: Managing patients with an elevated BP reading in the community pharmacy setting is complex and not standardized. Referral to an external health care provider, including the ED, was a common theme. The development of a pharmacy referral tool/algorithm may be helpful to refer in-store patients with elevated BP readings to the most appropriate healthcare resources.
