Brief Summary

The main objective of this RE-SAMPLE cohort study is to identify from a real-world data (RWD) set that will be collected, a subset of data that can be potentially used as important predictors and parameters for disease progression of COPD and complex chronic conditions, and multi-morbid exacerbations. The secondary objective is to evaluate the feasibility of RWD collection from a patient's perspective. Study design: This is a prospective observational cohort study to collect RWD in patients with COPD and complex chronic conditions, with a maximum of 38 months of follow-up. Measurements are performed and RWD are collected by using the Healthentia mobile phone application at baseline (e.g. patient characteristics), daily (e.g. symptom diary), during follow-up visits and at deterioration, and from hospital data (e.g. healthcare visits). The choice of parameters and measurement tools that will be collected during the cohort will be updated every three months during the first year of the cohort (via protocol amendments). These updates are based on citizen-design sessions and on new literature insights. Prognostic models will be developed including predictors derived from the RWD collection.

Outcome Measures

Primary Outcomes (1)

  • Predictors for exacerbations of COPD and comorbidities

    Prognostic performance of the validated predictive model for COPD and comorbid exacerbations and disease progression from RWD. The measures for progression will be survival, based on all-cause mortality, as well as morbidity. Morbidity is defined as time until first hospitalisation for an acute exacerbation of COPD and CCC, time until first moderate COPD exacerbation, time until first pneumonia, and total number of COPD and CCC exacerbations (extracted from daily symptom diaries) and pneumonia.

    Through study completion, an average of 2.5 years.

Secondary Outcomes (2)

  • Feasibility of the RWD collection.

    Through study completion, an average of 1 year.

  • Feasibility of the RWD collection.

    Through study completion, an average of 1 year

Sampling MethodNon-Probability Sample
Study Population

We aim to enroll 710 patients with both COPD and complex chronic conditions over 28 months (July 2021 until October 2023). Patients will be followed-up for a 38-month period (July 2021 until August 2024). These patients will be recruited from one of the three pilot sites (n=263 from Medisch Spectrum Twente, Netherlands); n=263 from Policlinico Universitario Fondazione Agostino Gemelli, Italy; n=184 from Tartu Ülikooli Kliinikum, Estonia.

You may qualify if:

  • Clinical diagnosis of COPD according to the GOLD criteria \[5\] (FEV1 \< 80% of the predicted value and FEV1/FVC \< 0.70);
  • Patients can be included both at stable state and during exacerbation/hospitalization;
  • At least one comorbidity:
  • Under treatment at one of the pilot sites (MST, TUK, GEM);
  • \>40 years of age;
  • Smoker or ex-smoker;
  • Able to understand, read and write the language spoken in the country of the pilot site.
  • Accessibility to internet;
  • Written informed consent from the subject prior to participation.
  • Furthermore, 25% of the patients should also have ≥ 2 exacerbations, defined as respiratory problems that required a course of oral corticosteroids / antibiotics in the two years preceding study entry; and/or ≥ 1 hospitalisation for respiratory problems in the two years preceding study entry; and/or modified MRC (mMRC) score of 3 or 4 (COPD patients with these scores have a higher chance of exacerbating).

You may not qualify if:

  • Serious other diseases with a low survival rate;
  • Presence of any other active lung disease (e.g., sarcoidosis);
  • Severe psychiatric illness, diagnosed by anamnesis;
  • Maintenance therapy with antibiotics
  • Patients with cognitive impairment (Mini Mental State Examination (MMSE) \< 24)
