Heat adaptation digital messaging
Digital messages to equip and prepare patients for extreme heat events. The first message will to encourage patients to prepare by creating a heat safety plan, and to form Check-in Companion groups among friends, neighbours, and relatives as well as to connect patients with existing key infrastructure that can be vital during heat events (ex: cooling stations and public facilities with air conditioning). When a heat-advisory is announced, additional messages will be sent to alert patients in the Treated group to activate their heat safety plans.

- +Must be using Cliniconex or Qualtrics as a practice tool for communication enabling outreach before the patients are invited to consent to participate in the study.
Exclusion
- −Patients who do not read French or English will be excluded from the study as they will not be able to give informed consentInformed consentThe process of being told what taking part involves, then choosing freely.Read more → or to fill out the surveys. Patients who do not have an email address or text messaging service will be excluded for the same reason. Minors, patients with dementia and people who cannot read and write in English or French will not be eligible because the automated approach to surveying patients makes it impractical to properly obtain their consent.

About This Trial
Extreme heat events pose a significant health threat in Canada, as demonstrated by the 2021 heat wave that claimed over 600 lives in Western Canada. Most heat-related deaths occur indoors and are preventable. Primary care providers (PCPs), who serve 88% of Canadians, are uniquely positioned to identify and support at-risk individuals. Heat Smart, in alignment with Heat Alert and Response Systems (HARS), aims to bridge the gap between primary care and public health to enhance community resilience and reduce health inequities related to extreme heat events. This randomized control trial in Eastern Ontario will examine whether patients receiving tailored digital health messages from their family physician or nurse practitioner change their behaviour to protect themselves from extreme heat-related illness. The Heat Smart study will: * Assess risk: Analyze electronic medical records and patient surveys to identify vulnerable individuals. * Deliver tailored messages: Send personalized digital guidance via e-mail or text, offering heat safety advice and local resource information in English and French. * Issue early warning alerts: Notify at-risk patients of upcoming heat events, prompting action. * Evaluate impact: Use surveys and health data to measure effectiveness in reducing heat-related health impacts. Short-term outcomes include increased awareness and preparedness among patients about heat-related health risks. Long-term goals involve scaling the intervention across Canada to reduce heat-related illnesses, enhance social connectedness, and decrease healthcare utilization.
