Impact of Comprehensive Health Resort Treatment on Insomnia and Quality of Life in Older Adults: A Pre-Experimental Study

Introduction: Sleep disorders are common in older adults, and quality of life is often diminished due to gradual declines in physical and mental abilities. Among the treatment strategies routinely applied in older adults, comprehensive health resort treatment is considered a promising option because of its multifaceted nature and low risk of adverse effects. Objective: The primary objective of this study was to evaluate the impact of comprehensive health resort treatment on insomnia and quality of life in older adults. The secondary objective was to examine whether treatment-induced changes in these parameters were associated with participants’ age. Material and Methods: The study group consisted of 83 participants (14 men and 69 women) with a mean age of 71.94 ± 6.00 years who underwent a 21-day comprehensive, individually tailored health resort treatment for degenerative joint disease. Insomnia was assessed using the Athens Insomnia Scale. Health-related quality of life was evaluated with the European Quality of Life Five Dimensions—Five Levels (EQ-5D-5L) instrument. Assessments were conducted twice: upon admission to and discharge from the sanatorium. Results: The mean Athens Insomnia Scale (AIS) score at baseline was 6.97 ± 6.21 across all participants. Following treatment, the AIS score decreased to 4.78 ± 4.95 (p < 0.0001). The baseline mean EQ-5D-5L index was 0.956 ± 0.064. After health resort treatment, the mean EQ-5D-5L index increased to 0.969 ± 0.042 (95% CI: 0.006 to 0.022; p = 0.001). Age was not associated with the magnitude of changes in the AIS score, EQ-5D-5L index or EQ-5D-5L VAS in the studied population. Conclusions: Comprehensive health resort treatment was associated with improvements in insomnia severity and quality of life in older adults, with similar changes observed across age groups. These findings suggest that comprehensive health resort treatment may be a beneficial component of geriatric health care.
