What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

Researchers in Pakistan are testing whether a mobile app that uses artificial intelligence to send personalized heat-risk alerts can reduce heat-related illness symptoms in adults with chronic conditions such as hypertension, diabetes, kidney disease, heart disease, or obesity. The app combines each person's clinical details with the day's forecast maximum temperature to classify their risk and deliver tailored heat-health messages. A control group receives a generic heat advisory through the same app. The trial measures symptom burden and heat-protective behaviors over six weeks.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
an AI-assisted personalized heat-risk alert system delivered through a mobile app
What this could lead to
If it works, this could offer a low-cost way to protect people with chronic conditions from heat-related illness as extreme heat becomes more common.
What could go wrong
The trial is small and runs for six weeks, so it may not show a clear benefit or may not apply to other settings. Alerts can also be ignored, and phone access or network issues could limit their reach.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 120 people

The number the study aims to enrol. It can still change while the study runs.

Started

Sep 2026

Expected to finish

Oct 2026

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

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.
