What causes vulnerability in older adults with serious diseases and how it affects care decisions

Official title: A COhort Study on Factors Leading to Vulnerability in Adult Patients With Serious Medical cOnditionS: the COSMOS-I Trial

Run by Tampere University Hospital · NCT07740239 · Data updated 2026-11-12

This study tests how often vulnerability factors appear in older adults with serious illnesses and how these factors influence treatment timing, survival, and quality of life.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 60 or older (or 18+ for specific conditions) with severe non-malignant diseases or locally/advanced/advanced cancers and recent imaging or treatment activity, recruited at participating centers in Tampere, Kuopio, or Oulu.

Probably not a fit

Patients without vulnerability factors or those not undergoing changes in treatment plans may have limited immediate benefit from the screening.

What this trial studies

This prospective, multicenter observational study will enroll about 1,500 adults aged 60 and older (with specific cancer and non-cancer conditions) across Finnish university hospitals. It aims to identify causes of generalized vulnerability, see how these factors relate to time to a full palliative treatment approach, and examine their impact on overall survival and patient-reported quality of life. The study will also assess whether common screening tools for vulnerability perform well in older adults with cancer. Data collection includes imaging and clinical procedures relevant to vulnerability assessment. Results could inform more tailored care planning for vulnerable older patients facing serious illness.

Why it matters

Potential benefit: If successful, the study could improve early identification of vulnerability and support personalized care decisions for older patients with serious diseases.

How similar studies have gone: Prior studies in vulnerability and frailty in older adults with cancer and non-cancer illnesses have shown promising associations with outcomes, but this cohort study is distinct in its multicenter design and focus on generalized vulnerability.
