Objective: The use of multiple medications is frequently observed in older people, especially in those with multimorbidity. The so-called polypharmacy has been associated with adverse health-related outcomes. In particular, among the most serious consequences of polypharmacy the risk of falls and consequent fractures are well-established [1,2]. However, it is noteworthy that the frailest individuals are often excluded from clinical research, limiting the applicability of evidence to specific populations. Older persons with chronic kidney disease (CKD) undergoing hemodialysis indeed represent a growing population of patients characterized by high vulnerability but still marginally studied. Aim of the study was to explore the relationship between the number of prescriptions and fractures in older patients with CKD undergoing hemodialysis. Methods: A retrospective, cross-sectional study was conducted on data coming from 107 older patients with CKD undergoing hemodialysis. Sociodemographic, clinical, and biological data were recorded. A 24- item Frailty Index (FI) was computed according to the model proposed by Searle and colleagues. Unadjusted and adjusted logistic regression models were performed to test the association of prescribed medications with history of fractures. Results: A total of 107 older patients undergoing hemodialysis were included in the study. The mean patient age was 79.1 (standard deviation, SD=7.7) y; 38 (35.5%) participants were women. The mean number of prescribed medications was 9.94 (SD=3.87). The median FI was 0.25 (interquartile range, IQR=0.17-0.29). The number of prescribed medications was significantly associated with fractures (OR 1.18, 95%CI 1.06-1.32, p = 0.003), even after adjustment for potential confounders (OR 1.16, 95%CI 1.03-1.30, p = 0.016). Conclusion: The number of medications is associated with fractures in a population of frail older people undergoing hemodialysis. Further studies are needed to clarify the cause-effect relationship between polypharmacy and fractures in older persons with severe CKD. If the number of medications will be confirmed as a risk factor for fracture, interventions based on deprescribing will become essential in older persons with CKD undergoing hemodialysis.

Abstract
Objective: The use of multiple medications is frequently observed in older people, especially in those with multimorbidity. The so-called polypharmacy has been associated with adverse health-related outcomes. In particular, among the most serious consequences of polypharmacy the risk of falls and consequent fractures are well-established [1,2]. However, it is noteworthy that the frailest individuals are often excluded from clinical research, limiting the applicability of evidence to specific populations. Older persons with chronic kidney disease (CKD) undergoing hemodialysis indeed represent a growing population of patients characterized by high vulnerability but still marginally studied. Aim of the study was to explore the relationship between the number of prescriptions and fractures in older patients with CKD undergoing hemodialysis. Methods: A retrospective, cross-sectional study was conducted on data coming from 107 older patients with CKD undergoing hemodialysis. Sociodemographic, clinical, and biological data were recorded. A 24- item Frailty Index (FI) was computed according to the model proposed by Searle and colleagues. Unadjusted and adjusted logistic regression models were performed to test the association of prescribed medications with history of fractures. Results: A total of 107 older patients undergoing hemodialysis were included in the study. The mean patient age was 79.1 (standard deviation, SD=7.7) y; 38 (35.5%) participants were women. The mean number of prescribed medications was 9.94 (SD=3.87). The median FI was 0.25 (interquartile range, IQR=0.17-0.29). The number of prescribed medications was significantly associated with fractures (OR 1.18, 95%CI 1.06-1.32, p = 0.003), even after adjustment for potential confounders (OR 1.16, 95%CI 1.03-1.30, p = 0.016). Conclusion: The number of medications is associated with fractures in a population of frail older people undergoing hemodialysis. Further studies are needed to clarify the cause-effect relationship between polypharmacy and fractures in older persons with severe CKD. If the number of medications will be confirmed as a risk factor for fracture, interventions based on deprescribing will become essential in older persons with CKD undergoing hemodialysis.File | Dimensione | Formato | |
