Health Status and Morbidities in Resident Relatives of Patients With COPD

OBJECTIVES: Resident relatives of patients with chronic obstructive pulmonary disease (COPD) may play a major role in obtaining a healthy lifestyle for patients. Little is known about resident relatives. This study aimed to compare health status, morbidities, care dependency, and mobility between patients with COPD and their resident relatives. DESIGN: Cross-sectional study. PARTICIPANTS: Stable patients with moderate to very severe COPD (n = 194) and their resident relatives (n = 194) were visited in their home environment. MEASUREMENTS: Post-bronchodilator spirometry was assessed and generic health status was measured using the EuroQol-5 Dimensions and the Assessment of Quality of Life with 8 dimensions. Care dependency was measured using the Care Dependency Scale. Mobility was measured using the Timed "Up and Go" test (TUG). Morbidities (COPD, hypertension, anxiety and depression, obesity, and muscle wasting) were determined using accepted disease cutoff points and/or receiving specific treatment. RESULTS: Age (patients: 66.0 [8.7], resident relatives: 64.8 [9.7]) and gender (male patients: 53%, male resident relatives: 45%) were comparable. Patients had worse generic health status, higher level of care dependency, and worse mobility. 29% of the resident relatives had airflow limitation based on the Tiffeneau index and 19% based on the lower limit of normal, 33% were current smokers, and 92% had at least one chronic condition. Resident relatives more frequently had hypertension (46% versus 69%). CONCLUSION: Resident relatives of patients with COPD are often current smokers and often have undiagnosed morbidities. Although their health status is better compared with patients, their disease management and health behavior should also be considered when advising patients in obtaining a healthier lifestyle and also when involving them as informal caregivers.
