Health-related quality of life as predictor of mortality in end-stage renal disease patients: an observational study.

ABSTRACT:

Background

Health-related quality of life (HRQoL) is an important component of patient-centered outcomes and a useful parameter for monitoring quality of care. We assessed HRQoL, its determinants, and associations with mortality in patients with end-stage renal disease (ESRD).

Methods

Short Form-36 was used to assess HRQoL, its domain components, and physical (PCS) and mental (MCS) composite summary scores in altogether 400 (338 incident and 62 prevalent) dialysis patients with median age 64?years, 37% women, 24% diabetes mellitus (DM), 49% cardiovascular disease (CVD), and median estimated glomerular filtration rate (eGFR) of 5.3 (3.0-9.4) ml/min/1.73². Results were analyzed separately for 338 incident patients starting on hemodialysis (HD; 68%) or peritoneal dialysis (PD; 32%), and 62 prevalent PD patients. Mortality risk was analyzed during up to 60?months (median 28?months).

Results

Linear multivariate regression analysis showed that in incident dialysis patients, 1-SD higher PCS associated negatively with 1-SD higher age, DM and CVD, and positively with 1-SD higher hemoglobin and sodium (adjusted r² =?0.17). In 62 prevalent PD patients, 1-SD higher PCS was negatively associated with 1-SD higher age. MCS was not associated to any of the investigated factors. Multivariate Cox regression analysis showed that in incident dialysis patients, 1-SD increase of PCS associated with lower all-cause mortality, hazard ratio 0.65 (95% confidence interval 0.52-0.81), after adjustments for age, sex, DM, CVD, plasma albumin, C-reactive protein and eGFR whereas 1-SD lower MCS did not associate with mortality. In PD patients, neither PCS nor MCS associated with mortality.

Conclusions

MCS did not associate with any of the investigated clinical factors, whereas lower PCS associated with higher age, CVD, DM, and lower hemoglobin and sodium levels. MCS was not associated with mortality, whereas lower PCS associated with increased mortality risk. These results suggest that HRQoL - in addition to its role as patient-centered outcome - matters also for hard clinical outcomes in ESRD patients. Our knowledge about factors influencing MCS in ESRD patients is limited and should motivate further studies.

Project description:BackgroundThe Severe Respiratory Insufficiency (SRI) questionnaire is a specific measure of health-related quality of life (HRQoL) in patients treated with long-term mechanical ventilation (LTMV). The aim of the present study was to examine whether SRI sum scores and related subscales are associated with mortality in LTMV patients.MethodsThe study included 112 LTMV patients (non-invasive and invasive) from the Norwegian LTMV registry in Western Norway from 2008 with follow-up in August 2014. SRI data were obtained through a postal questionnaire, whereas mortality data were obtained from the Norwegian Cause of Death Registry. The SRI questionnaire contains 49 items and seven subscales added into a summary score (range 0-100) with higher scores indicating a better HRQoL. The association between the SRI score and mortality was estimated as hazard ratios (HRs) with 95% confidence intervals (95% CI) using Cox regression models and HRs were estimated per one unit change in the SRI score.ResultsOf the 112 participating patients in 2008, 52 (46%) had died by August 2014. The mortality rate was the highest in patients with chronic obstructive pulmonary disease (75%), followed by patients with neuromuscular disease (46%), obesity hypoventilation syndrome (31%) and chest wall disease (25%) (p?<?0.001). Higher SRI sum scores in 2008 were associated with a lower mortality risk after adjustment for age, education, hours a day on LTMV, time since initiation of LTMV, disease category and comorbidity (HR 0.98, 95% CI: 0.96-0.99). In addition, SRI-Physical Functioning (HR 0.98, 95% CI: 0.96-0.99), SRI-Psychological Well-Being (HR 0.98, 95% CI: 0.97-0.99), and SRI-Social Functioning (HR 0.98, 95% CI: 0.97-0.99) remained significant risk factors for mortality after covariate adjustment. In the subgroup analyses of patient with neuromuscular diseases we found significant inverse associations between some of the SRI subscales and mortality.ConclusionsSRI score is associated with mortality in LTMV-treated patients. We propose the use of SRI in the daily clinic with repeated measurements as part of individual follow-up. Randomized clinical trials with interventions aimed to improve HRQoL in LTMV patients should consider the SRI questionnaire as the standard HRQoL measurement.

Project description:BackgroundOlder patients with end-stage renal disease (ESRD) have experienced diminished quality of life and debilitating symptoms. Conservative management may be a potential treatment option. Currently, limited studies have been conducted about the main outcome of conservative management, including quality of life, symptoms and sleep quality. The aim of this systematic review was to examine the quality of life, symptoms and sleep quality of elderly patients with ESRD undergoing conservative management.MethodsEvidence-based medicine database (JBI and Cochrane) and original literature database (PubMed, Medline, EMbase, Web of Science) were searched up to March 12, 2018. The quality of included papers was evaluated with the Newcastle-Ottawa Scale.ResultsEight studies met the inclusion criteria. The total of 1229 patients were involved with an average age of 60.6 ~ 82 years. Patients choosing conservative management were older and more functionally impaired compared to those opting for dialysis. 55% patients undergoing conservative management had stable or improved quality of life and symptoms in prospective cohort study. However, the results revealed that there were no significant differences in quality of life and symptom between conservative management and renal replacement therapy. Only one study assessed quality of life of older patients using SF-36, with a lower score in physical health subscale of conservative management patients than those of renal replacement therapy. Although more than 40% of the patients had poor sleep quality, no significant difference was found between conservative management and renal replacement therapy. Sleep disorders were associated with fatigue and other symptoms.ConclusionsAlthough there is a limited literature, conservative management is likely to improve quality of life and alleviate symptoms of end-stage renal disease patients with considerable clinical implications mainly in elderly patients. Future study should pay more attention to the various treatment outcomes of conservative management, providing abundant evidence.

Project description:BackgroundPrevious studies have demonstrated that early pre-end-stage renal disease (ESRD) nephrology care could improve postdialysis prognosis. However, less is known about the specific types of interventions responsible for the improved outcomes. We hypothesized that more frequent predialysis laboratory testing is associated with better postdialysis outcomes in incident ESRD patients.MethodsIn all, 23?089 patients with available outpatient laboratory tests performed during the 2-year predialysis (i.e. prelude) period were identified from a total of 52?172 American veterans with chronic kidney disease (CKD) transitioning to dialysis between October 2007 and September 2011. The associations between the frequency of combined laboratory tests, including serum creatinine, serum potassium and hemoglobin (test trio), with postdialysis mortality and hospitalization were examined in multivariable adjusted Cox and logistic regression models.ResultsWhen entering the 2-year prelude period, the mean age (Standard Deviation) of the patients was 66.2 (SD 11.3)?years and the mean estimated glomerular filtration rate was 46.8 (SD 23.9)?mL/min/1.73 m2. In all, 14% of patients had the test trio performed less than twice in 24?months and 8.9% had the trio measured more often than every other month. Over a 2.5-year median postdialysis follow-up period, 15?303 (66.3%) patients died (mortality rate 260/1000 patient-years). The adjusted hazard ratio of all-cause mortality and adjusted odds ratio of the composite of hospitalization or death associated with lab testing done >12/24?months compared with 2-?4/24 months were 0.68 [95% confidence interval (CI) 0.65-0.73] and 0.70 (95% CI 0.62-0.79), respectively.ConclusionsMore frequent laboratory testing in patients with advanced CKD is associated with better clinical outcomes after dialysis. Further examination in clinical trials is needed before the implementation of more frequent laboratory testing in clinical practice.
