AI-powered personalized heat risk alerts for adults with chronic conditions

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This randomized controlled trial will compare an AI-assisted, personalized heat-risk alert system to a generic heat advisory in a six-week study among adults with chronic conditions at a hospital in Gujranwala, Pakistan. On days with very hot forecasts, the AI system classifies participants into low, moderate, or high risk and sends tailored alerts, while the control group gets standard advisories. The primary outcome is the Heat-Related Illness Symptom Score at six weeks; secondary outcomes include protective behaviors and knowledge about heat health. The study aims to determine whether personalization improves responses to extreme heat exposure in vulnerable adults.

Why it matters

Who can join: the full rules

Inclusion Criteria:

* Adults aged 18 years or older attending the outpatient department of the selected tertiary-care hospital during the recruitment period.
* Have a documented diagnosis of at least one chronic non-communicable disease associated with increased susceptibility to heat-related illness, including hypertension, type 2 diabetes mellitus, chronic kidney disease, cardiovascular disease, or obesity (BMI ≥30 kg/m²).
* Have access to a personal smartphone capable of receiving study heat-risk alert notifications.
* Be able to read Urdu or English, or have a household member/caregiver available to read and explain study alerts when required.
* Be willing and able to provide written informed consent.
* Intend to remain within the study catchment area for the duration of the six-week study period to facilitate follow-up.

Exclusion Criteria:

* Patients requiring immediate emergency treatment or hospital admission at the time of recruitment.
* Individuals with severe cognitive impairment, dementia, psychotic illness, or another medical condition that limits their ability to understand study procedures or provide informed consent.
* Patients with terminal illness or those receiving palliative care.
* Individuals with severe visual, hearing, or communication impairments that prevent effective receipt of the study alert intervention and outcome assessment without a reliable caregiver.
* Pregnant women, because pregnancy has distinct physiological responses to heat exposure and would require separate clinical risk stratification beyond the scope of this study.
* Participants currently enrolled in another clinical trial or structured behavioral intervention related to heat-health, climate adaptation, or chronic disease self-management.
* Participants who are unable or unwilling to comply with study procedures or complete the required follow-up assessment.
