Prevalence and co-incidence of geriatric syndromes according to glomerular filtration rate in older patients.

BACKGROUND

Geriatric syndromes are complex clinical manifestations and significant causes of mortality and morbidity. This study was aimed to determine the frequency and co-incidence of geriatric syndromes in older patients with chronic kidney disease (CKD).

METHODS

Older patients were included in this cross-sectional retrospective study. All patients were questioned in terms of geriatric syndromes including dementia, polypharmacy, malnutrition, frailty, probable sarcopenia, urinary incontinence, falls, fear of falling, depression, insomnia, and excessive daytime sleepiness. Geriatric syndromes were evaluated according to Glomerular Filtration Rate (GFR) ≥ 60 ml/min/1.73 m2, 30-59 ml/min/1.73 m2 and < 30 ml/min/1.73 m2.

RESULTS

Of the 1320 patients included, the mean age was 79.6 ± 7.8 and 929 (70%) were female. GFR groups ≥ 60 ml/min/1.73 m2, 30-59 ml/min/1.73 m2, and < 30 ml/min/1.73 m2 comprised of 55%, 38%, and 7% patients, respectively. The rate of ≥ 3 syndromes in the same person was 66.4% in the group with GFR ≥ 60 ml/min/1.73 m2. After age and sex adjusted; it was observed that frailty was 2.5 times, probable sarcopenia 2.4 times, and malnutrition 2.7 times more in those with GFR 30-59 ml/min/1.73 m2 compared to those with GFR ≥ 60 ml/min/1.73 m2 (p < 0.05). Dementia 1.4, frailty 1.55, polypharmacy 2.0, and urinary incontinence were 1.6 times more common in those with a GFR < 30 ml/min/1.73 m2 (p < 0.05).

CONCLUSIONS

Each of the geriatric syndromes and their co-incidence are high in older CKD patients. Geriatricians and nephrologists should be aware of geriatric syndromes in older CKD patients, and they should cooperate for the management of these patients.
