Chronical Illness-related Limitations of the Ability to Cope With Rising Temperatures, Third Wave

NCT06890208 | Recruiting

• 1 other identifier: LPEK-0887
• Study Type: observational
• Target: 240
• Locations: 1 country
• Sites: 1

Brief Summary

The CLIMATE-III Observational Study examines to what extent chronically ill patients experience adverse health effects because of heat and whether the patients' specific health behavior, somatosensory amplification, risk and benefit perception, self-efficacy, health literacy, and the degree of urbanisation of the patients' administration district are associated with these effects. Study participants from Germany and Italy will be included in the sample.

Conditions

Coronary Disease; Myocardial Infarction; Heart Failure; Arrhythmias, Cardiac; Peripheral Artery Disease; Stroke; Ischemic Attack, Transient; Diabetes Mellitus, Type 1; Diabetes Mellitus, Type 2; Pulmonary Disease, Chronic Obstructive; Asthma; Renal Insufficiency; Depressive Disorder; Anxiety Disorders; Schizophrenia; Peripheral Nervous System Diseases

Outcome Measures

Primary Outcomes (1)

• Summary score of severity of adverse health effects

  Observed adverse health effects include nausea, vomiting, tiredness/fatigue, vertigo, circulation problems/syncopes, muscle cramps, headache, extrasystoles, palpitations, edemas, shortness of breath, depressive mood, anxiety, and mental confusion. The severity in each symptom category is defined by the degree of limitations in usual activities from 0=none to 4=very severe. The summary score is calculated by adding the severity of each symptom category.

  15 May 2025 to 30 September 2025

Secondary Outcomes (3)

• Summary score of participants' implementation of protective behavior against heat

  15 May 2025 to 30 September 2025

• Self-rated health

  15 May 2025 to 30 September 2025

• Level of medical service use

  15 May 2025 to 30 September 2025

• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Probability Sample

Study Population

The study is located in different sites in Germany and Italy. Patients from approximately 30 GP practices will be included (15 GP practices in Germany and 15 GP practices in Italy). In each practice, eligible patients receive a flyer including a QR-Code and a short link to register for the online study. After documenting informed consent within the application, patients fill out the baseline questionnaire and receive invitations for 12 subsequent assessments of symptoms by email. The investigators estimated that approximately 1,200 patients will be contacted. From experience with similar studies the investigators anticipated a response rate of 20% (=240 patients).

You may qualify if:

• being 18 years or older
• at least one of the following conditions: Coronary Heart Disease; Myocardial Infarction; Heart Failure; Cardiac Arrhythmias; Peripheral Artery Disease; Stroke; Transient Ischemic Attack; Diabetes Mellitus (Type 1 or 2); Chronic Obstructive Pulmonary Disease; Asthma; Renal Insufficiency; Depressive Disorder; Anxiety Disorders; Schizophrenia; Peripheral Nervous System Diseases.

You may not qualify if:

• no capacity to consent
• severe visual impairment
• insufficient German language skills
• not able to use internet browser (eg, lack of hardware)
