Shop-to-Stop Hypertension: A public screening campaign to detect and manage raised blood pressure in Australian adults

Participants screened and detected with high blood pressure (greater than or equal to 140/90 mmHg) at a SiSU (registered brand name) Health kiosk Station in Bunnings will receive text message-based nudges to a) return for a repeat SiSU Health Station blood pressure check b) visit their GP to check and manage their blood pressure and c) improve their self-care. Participants will have new data captured at each visit they attend a SiSU Health Station over the 12 month study period (study period is defined as 12 months from the date the SiSU Health Station is 'active' for data collection). Although participants are encouraged to attend for a re-check at a SiSU Health Station, this is not a requirement of study participation. Along with blood pressure measures, SiSU health Stations will also be measuring: weight and height (which automatically calculates BMI), body composition, and heart rate, Each visit will take approximately 5-10 minutes to complete. Participants will be able to independently and accurately measure blood pressure without the need for supervision or assistance of other study members. Additionally, no assistance will be required for participants to complete the questions or health measures at the Health Stations. Participants are nudged to go to their general practitioner for further evaluation and management via text messages.. These will be automatically sent using SiSU's text message delivery systems incorporated into the Health Stations that can track delivery of the messages. Messages will be sent to participants at 1 week, 2 weeks and 12 weeks post their initial screening. Messages have been co-designed specifically for this study by consumers, clinicians, and investigators who are experts in messaging design . There are no other readily-available resources for this study. Text message content include: * Encouragement for a recheck of blood pressure at week 1: 'you recorded high blood pressure at the Bunnings health check station. High blood pressure increases your risk of stroke and heart attack. To understand if your blood pressure needs treatment, Cardiologists and heart health researchers at The University of New South Wales would like to remind you to re-check your blood pressure often, ideally within the next 7 days at Bunnings.', * Improve self-care at week 2: 'It is important to check in and have your blood pressure re-checked often. If you have high blood pressure, visit your doctor who can recommend diet and lifestyle changes or treatment options that are effective. Since your first visit, have you re-checked your blood pressure at a SiSU health station at Bunnings again?' * Return for follow up at week 12: 'Blood pressure levels can change over time. To prevent a stroke or heart attack, it’s a good idea to have your blood pressure rechecked this week at a SiSU health station in Bunnings. Have you visited your doctor since you recorded a high blood pressure?' All participants (regardless of blood pressure levels) will also receive an email message after their screening to provide their health check results (including blood pressure) and a link to download the SiSU Health phone app with encouragement to adopt a healthy lifestyle. Adherence to the requests will be captured either at a follow up SiSU health station recheck, response to questions on the kiosk on whether they’ve visited their GP recently, and in response to the questions from the text message nudges.
