Predialysis therapeutic care and health-related quality of life at dialysis onset (The pharmacoepidemiologic AVENIR study).

Abstract : BACKGROUND: To determine the impact of the quality of pre-dialysis nephrological care on health-related quality of life (HRQoL) at dialysis onset, which has not been well evaluated. METHODS: All adults who began a dialysis treatment in the administrative region of Lorraine (France) in 2005 or 2006, were enrolled in this prospective observational study. HRQoL was measured using the Kidney Disease Quality of Life V36 questionnaire, which enables calculation of two generic (physical and mental) and three specific dimensions (Symptoms/problems, Effects and Burden of kidney disease). The specific dimensions were scored from 0 to 100 (worst to best possible functioning). Pre-dialysis nephrological care was measured using three indicators: quality of therapeutic practices (evaluated across five main aspects: hypertension/proteinuria, anemia, bone disease, metabolic acidosis and dyslipidemia), time since referral to a nephrologist and number of nephrology consultations in the year preceding dialysis treatment. RESULTS: Two thousand and eighty-three (67.4%) patients were referred to a nephrologist more than 1 month before dialysis initiation and completed the HRQoL questionnaire. Quality of therapeutic practices was significantly associated with the Mental component. Time since referral to a nephrologist was associated with Symptoms/problems and the Effects of kidney disease dimensions, but no relationship was found between the number of nephrology consultations and HRQoL. CONCLUSIONS: HRQoL at dialysis onset is significantly influenced by the quality of pre-dialysis nephrological care. Therefore, disease management should be emphasized.
