Health-related quality of life predicts outcomes but is not affected by peritoneal clearance: The ADEMEX trial

BACKGROUND: We hypothesized that increasing small solute clearance in peritoneal dialysis (PD) would lead to improvements in patient health-related quality of life (HRQOL). METHODS: Patients were randomized to a control group [standard 4 x 2 L continuous ambulatory peritoneal dialysis (CAPD)] and an intervention group (CAPD with a target creatinine clearance >/=60 L/week/1.73 m(2)). The Kidney Disease Quality of Life Short Form was obtained at baseline and at 6, 12, and 24 months. Physical (PCS), mental (MCS), and kidney disease component summary (KDCS) scores were computed. RESULTS: The two groups were comparable at baseline with respect to HRQOL. Baseline variables highly predictive of better QOL included absence of diabetes, younger age, higher starting GFR, and serum albumin. Baseline values of QOL were highly predictive of survival and hospitalizations. An unadjusted comparison revealed that patients in the intervention group had significantly higher PCS and KDCS scores at six months. However, there were no significant differences between the intervention and control patients at 12 or 24 months. When similar analyses were carried out adjusting for different patterns of patient dropout, there were no significant differences between the two groups at any time point in terms of PCS, MCS, and KDCS scores. CONCLUSION: We found no evidence of a long-term benefit in HRQOL of CAPD patients by increasing peritoneal small-solute clearances when HRQOL parameters were adjusted for patient dropout. Measures of HRQOL have a significant predictive value for patient survival and hospitalizations.     

Health-related quality of life as a predictor of mortality and hospitalization: the Dialysis Outcomes and Practice Patterns Study (DOPPS)

BACKGROUND: We investigated whether indicators of health-related quality of life (HRQOL) may predict the risk of death and hospitalization among hemodialysis patients treated in seven countries, taking into account serum albumin concentration and several other risk factors for death and hospitalization. We also compared HRQOL measures with serum albumin regarding their power to predict outcomes. METHODS: We analyzed data from the Dialysis Outcomes and Practice Patterns Study (DOPPS), an international, prospective, observational study of randomly selected hemodialysis patients in the United States (148 facilities), five European countries (101 facilities), and Japan (65 facilities). The total sample size was composed of 17,236 patients. Using the Kidney Disease Quality of Life Short Form (KDQOL-SFTM), we determined scores for three components of HRQOL: (1) physical component summary (PCS), (2) mental component summary (MCS), and (3) kidney disease component summary (KDCS). Complete responses on HRQOL measures were obtained from 10,030 patients. Cox models were used to assess associations between HRQOL and the risk of death and hospitalization, adjusted for multiple sociodemographic variables, comorbidities, and laboratory factors. RESULTS: For patients in the lowest quintile of PCS, the adjusted risk (RR) of death was 93% higher (RR = 1.93, P < 0.001) and the risk of hospitalization was 56% higher (RR = 1.56, P < 0.001) than it was for patients in the highest quintile level. The adjusted relative risk values of mortality per 10-point lower HRQOL score were 1.13 for MCS, 1.25 for PCS, and 1.11 for KDCS. The corresponding adjusted values for RR for first hospitalization were 1.06 for MCS, 1.15 for PCS, and 1.07 for KDCS. Each RR differed significantly from 1 (P < 0.001). For 1 g/dL lower serum albumin concentration, the RR of death adjusted for PCS, MCS, and KDCS and the other covariates was 1.17 (P < 0.01). Albumin was not significantly associated with hospitalization (RR = 1.03, P> 0.5). CONCLUSION: Lower scores for the three major components of HRQOL were strongly associated with higher risk of death and hospitalization in hemodialysis patients, independent of a series of demographic and comorbid factors. A 10-point lower PCS score was associated with higher elevation in the adjusted mortality risk, as was a 1 g/dL lower serum albumin level. More research is needed to assess whether interventions to improve quality of life lower these risks among hemodialysis patients.     

Predictors and Outcomes of Health‐Related Quality of Life in Caregivers of Cardiothoracic Transplant Recipients

Cardiothoracic transplant programs generally require that transplant recipients have family caregivers to assist them posttransplant. The burden of caregiving on the family members remains poorly understood. If caregivers’ well‐being is compromised by caregiving, it may bode poorly for transplant recipients’ own health in the long‐term posttransplant. We examined caregiver health‐related quality of life (HRQOL) during the first year after their family member's transplant, its predictors and its relationship to subsequent patient survival. Adult (aged 18+) caregivers of 242 cardiothoracic transplant recipients (lung = 134; heart = 108) completed assessments of demographics, psychosocial characteristics and caregiver burden at 2 months posttransplant, and HRQOL at 2, 7 and 12 months posttransplant. Recipients’ survival time was obtained from medical records. Caregiver HRQOL was generally high across the first‐year posttransplant in emotional and social functioning; caregiver physical functioning significantly worsened. There were no differences by type of recipient transplant. Greater caregiver burden predicted poorer caregiver HRQOL in several physical domains at 12 months posttransplant. Transplant recipients whose caregivers had lower perceived general health at 12 months posttransplant showed poorer survival rates during the subsequent 7 years of follow up. Transplant teams should identify those caregivers at risk for poorer general health posttransplant to maximize positive outcomes for the entire family.     

Effect of lower extremity amputation on caregiving burden in caregivers of patients with diabetic foot: Prospective cohort study

Lower extremity amputation as a treatment of diabetic foot ulcer is probably a major burden for the patient's family and friends, who typically act as caregivers and support the patient in coping with the physical disabilities and emotional distress. In the present prospective study, we investigated the effects of different lower extremity amputation levels for diabetic foot ulcer treatment on caregivers of patients with diabetes using the Zarit Burden Interview (ZBI‐12) scale. Patients with diabetic foot ulcers who underwent unilateral major amputation (above‐below knee) and minor amputation of foot (heel sparing) and their caregivers were requested to volunteer to participate in this study from June 2016 to December 2018. The ZBI‐12 form was completed immediately preoperatively and 3 and 6 months after postoperatively. In the minor amputation group, the mean age of the 51 patients was 72.1 years. In the major amputation group, the mean age of the 88 patients was 73.7 years. Both groups of caregivers of patients with minor amputation and major amputations showed a significant improvement in ZBI‐12 score when compared preoperatively and at 3‐ and 6‐month follow‐up visits. The mean ZBI‐12 score was significantly higher in the major than in the minor amputation group in preoperative and all postoperative visits. The absence of the ankle joint in the below‐ or above‐knee amputation renders it more difficult for the amputee to quickly learn the use of prosthesis, thereby increasing the burden of the patient and caregivers. We found that lower extremity amputation for the treatment of chronic diabetic foot ulcers has significantly favourable effect on the caregiver burden, and thereby heel sparing was considerably more effective for the caregiver burden.     

Quality of life in children with chronic kidney disease-patient and caregiver assessments.

BACKGROUND: Children with chronic kidney disease (CKD) require strict dietary and lifestyle modifications, however, there is little information on their quality of life. Our objective was to compare health-related quality of life (HRQOL) in children with different stages of CKD to each other and to a control population. METHODS: A cross-sectional assessment of HRQOL for physical, emotional, social and school domains was performed using the PedsQL Generic Core Scale. Data were collected from 20 children with chronic renal insufficiency (CRI; creatinine > 200 micromol/l), 12 on maintenance haemodialysis or peritoneal dialysis (DIAL) and 27 with renal transplants (TX). Caregiver proxy reports were obtained for CRI (n = 20), DIAL (n = 17) and TX (n = 21). Between-group differences were assessed with ANOVA for the CKD groups; t-tests compared our CKD samples with controls. RESULTS: Children with CKD scored lower than the controls in all subscales, however, only TX compared with controls was significant (P < 0.02). DIAL children scored equal to or higher than the TX group in all domains. Analysis of covariance with number of medications as covariate yielded a significant result for the physical subscale (F = 8.95, df = 3, 53, P = 0.004). Proxy caregiver scores were lower than patient scores in all four domains. CONCLUSIONS: Children with CKD rate their HRQOL lower than the healthy controls do. It may be reassuring to caregivers that children on dialysis rate their HRQOL higher than would be expected. However, it is of some concern that caregiver perception of improved HRQOL following transplantation was not shared by their children in the present study.     

Quality of life of patients with chronic renal allograft rejection and anemia

BACKGROUND: The treatment with recombinant human erythropoietin (rHuEPO) of anemia associated with renal insufficiency (RI) improves the health-related quality of life (HRQOL) of those patients. The objective of this study was to evaluate the HRQOL of patients with chronic allograft nephropathy (CAN) and anemia associated to RI, and the effect of rHuEPO treatment on the HRQOL. METHODS: This prospective study consisted of 17 kidney transplant patients with RI caused by CAN and anemia who received rHuEPO. The hemoglobin (Hb) target was 12 g/dL. Serum Hb, hematocrit (Hct) and creatinine clearance (CrCl) were collected. HRQOL was evaluated with the Kidney Disease Quality of Life Short-Form 36 (SF-36) questionnaire at the start, at the 3rd and 6th month and at the end of the follow-up. SF-36 scores (eight scales, physical component summary (PCS) and mental component summary (MCS) were standardized by age and gender using the Spanish population norms. The "effect size" was also calculated for each score. RESULTS: Hb and Hct statistically improved from the start to the 3rd month and to the end of the study (p<0.01). Although the CrCl remained stable during most of the follow-up, it worsened (p=0.002) around the 13th month. SF-36 scores at the beginning were worse than that of the general population. Three SF-36 scales statistically improved; role-physical, vitality and mental health. The effect size was moderate for pain (0.41), role-emotional (0.39) and MCS (0.42); and large for role-physical (0.65), vitality (0.81) and mental health (0.74). CONCLUSIONS: The poor HRQOL of patients with CAN and anemia improves with rHuEPO treatment, the effect size varying from moderate to large.     

Quality of sleep and health-related quality of life in haemodialysis patients.

BACKGROUND: Sleep complaints are common in haemodialysis patients. In the general population, insomnia impacts negatively on health-related quality of life (HRQoL). The objective of this study was to examine the association between quality of sleep and HRQoL in haemodialysis patients independent of known predictors of HRQoL. METHODS: Quality of sleep was measured using the Pittsburgh Sleep Quality Index (PSQI) and HRQoL was measured using the Medical Outcomes Study 36-item Short Form (SF-36) in 89 haemodialysis patients. RESULTS: Sixty-three (71%) subjects were 'poor sleepers' (global PSQI >5). The SF-36 mental component summary (MCS) and physical component summary (PCS) correlated inversely with the global PSQI score (MCS, r = -0.28, P < 0.01; PCS, r = -0.45, P < 0.01). The PCS score also correlated with age (r = -0.24, P = 0.02), haemoglobin (r = 0.21, P = 0.048) and comorbidity (r = -0.40, P < 0.01), and mean PCS was lower in depressed subjects (26.2 vs 35.9, P = 0.02). Subjects with global PSQI >5 had a higher prevalence of depression, lower haemoglobin and lower HRQoL in all SF-36 domains. The global PSQI score was a significant independent predictor of the MCS and PCS after controlling for age, sex, haemoglobin, serum albumin, comorbidity and depression in multivariate analysis. CONCLUSIONS: Poor sleep is common in dialysis patients and is associated with lower HRQoL. We hypothesize that end-stage renal disease directly influences quality of sleep, which in turn impacts on HRQoL.     

Adolescent Health-Related Quality of Life Following Liver and Kidney Transplantation

Health perceptions of adolescent transplant patients should be considered in providing appropriate healthcare. OBJECTIVES: (i) quantify health-related quality of life (HRQOL) in adolescent liver and kidney transplant patients, (ii) compare caregiver ratings of their children's HRQOL to adolescent self-reports and (iii) examine the relationship between HRQOL and disease-specific disability (DSD). Adolescent liver (n = 51) and kidney (n = 26) transplant recipients and caregivers were surveyed using the CHQ-CF87 and CHQ-PF50. DSD scores were calculated for each patient. The response rate was >70%. Adolescent's psychological and physical health was similar to a healthy population, but general health poorer (p = 0.0006). Caretakers reported lower physical functioning and general health (p = 0.0001) but similar psychological health to a normative population. All caregivers expressed negative emotional impact of their child's health on themselves and family activities (p = 0.0001). Positive correlations were found between liver transplant recipients and caregivers: perceptions of behavior (ICC = 0.55, p < 0.001), mental health (ICC = 0.56, p < 0.001), self-esteem (ICC = 0.68, p 相似文献   

Health-related quality of life in end-stage renal disease patients: the effects of starting dialysis in the first year after the transition period

Background/aims

Prevalent dialysis patients have low scores of health-related quality of life (HRQOL) which are associated with increased risk of hospitalization and mortality. Also in CKD-5 non-dialysis patients, HRQOL scores seem to be lower as compared with the general population. This study firstly aimed to compare HRQOL between CKD-5 non-dialysis and prevalent dialysis patients in a cross-sectional analysis and to assess longitudinal changes over 1 year after the dialysis initiation. Secondly, the correlation between HRQOL and physical activity (PA) was explored.

Methods

Cross-sectional 44 CKD-5 non-dialysis, 29 prevalent dialysis, and 20 healthy controls were included. HRQOL was measured by Short Form-36 questionnaires to measure physical and mental domains of health expressed by the physical component summary (PCS) and mental component summary (MCS) scores. PA was measured by a SenseWear? pro3. Longitudinally, HRQOL was assessed in 38 CKD-5 non-dialysis patients (who were also part of the cross-sectional analysis), before dialysis initiation until 1 year after dialysis initiation.

Results

PCS scores were significantly lower both in CKD-5 non-dialysis patients and in prevalent dialysis patients as compared with healthy controls (p?<?0.001). MCS scores were significantly lower in both CKD-5 non-dialysis patients (p?=?0.003), and in dialysis patients (p?=?0.022), as compared with healthy controls. HRQOL scores did not change significantly from the CKD-5 non-dialysis phase into the first year after dialysis initiation. PA was significantly related to PCS in both CKD-5 non-dialysis patients (r?=?0.580; p?<?0.001), and dialysis patients (r?=?0.476; p?=?0.009).

Conclusions

HRQOL is already low in the CKD-5 non-dialysis phase. In the first year after dialysis initiation, HRQOL did not change significantly. Given the correlation between PCS score and PA, physical activity programs may be potential tools to improve HRQOL in both CKD-5 non-dialysis as well as in prevalent dialysis patients.

     

Patient function and caregiver burden after ambulatory surgery: a cohort study of patients older than 65

Purpose

The primary objective of this prospective cohort study was to assess the impact of ambulatory surgery on patient function one week and one month following surgery among surgical patients ≥ 65 yr of age. Secondary objectives were to determine whether changes in patient function were correlated with increased burden of care in the patient’s primary caregiver and with patient assessments of postoperative pain and quality of life.

Methods

Following Research Ethics Board approval, patients aged ≥ 65 yr undergoing elective ambulatory surgery and their caregivers were recruited. Patients completed the système de mesure de l’autonomie fonctionnelle (SMAF) and the Brief Pain Inventory. Primary caregivers completed the Zarit Burden Interview (ZBI). All measurements were obtained preoperatively and on postoperative days (POD) 7 and 30.

Results

Patient function decreased on POD 7 and had not returned to baseline on POD 30 (mean change in SMAF 6.9; 95% confidence interval (CI) 5.3 to 8.4 on POD 7 and mean change in SMAF 2.6; 95% CI 1.3 to 4.0 on POD 30). Interval changes in caregiver burden were not significant (mean change in ZBI ?0.4; 95% CI ?1.8 to 0.96 on POD 7 and mean change in ZBI ?0.6; 95% CI ?2.1 to 0.8 on POD 30). Decreased patient function was associated with increased caregiver burden at all time points (P < 0.001). Decreased caregiver function at baseline was also associated with higher ZBI (linear association 0.71; P = 0.02).

Conclusions

Patients exhibited reduced function seven days following ambulatory surgery. Patient function largely recovered by POD 30. Caregiver burden was variable and influenced by both patient and caregiver function. This trial was registered with Clinical Trials.gov (NCT01382251).     

Impact of community-level socioeconomic disparities on quality of life after burn injury: A Burn Model Systems Database study

IntroductionIndividual-level socioeconomic disparities impact burn-related incidence, severity and outcomes. However, the impact of community-level socioeconomic disparities on recovery after burn injury is poorly understood. As a result, we are not yet able to develop individual- and community-specific strategies to optimize recovery. Therefore, we aimed to characterize the association between community-level socioeconomic disparities and long-term, health-related quality of life after burn injury.MethodsWe queried the Burn Model System National Longitudinal Database for participants who were> 14 years with a zip code and who had completed a health-related quality of life (HRQOL) questionnaire (VR-12) 6 months after injury. BMS data were deterministically linked by zip code to the Distressed Communities Index (DCI), which combines seven census-derived metrics into a single indicator of economic well-being, education, housing and opportunity at the zip code level. Hierarchical linear models were used to estimate the association between community deprivation and HRQOL 6 months after burn injury, as measured by mental (MCS) and physical (PCS) component summary scores of the SF12/VR12.Results342 participants met inclusion criteria. Participants were mostly male (n = 239, 69 %) and had a median age of 48 years (IQR 33–57 years). Median %TBSA was 10 (IQR 3–28). More than one-third of participants (n = 117, 34 %) lived in a community within the highest two distress quintiles. After adjusting for age, race/ethnicity, number of trips to the operating room (OR) and pre-injury PCS, neighbourhood distress was negatively associated with 6-month PCS (ß-0.05, 95 % CI [−0.09,−0.01]). Increasing age and lower pre-injury PCS were also negatively associated with 6-month PCS. There was no observed association between neighbourhood distress and 6-month MCS after adjustment for age, participant race/ethnicity, number of trips to the OR and pre-injury MCS. Higher pre-injury MCS was associated with 6-month MCS (ß0.54, 95 % CI [−0.41,0.67]).ConclusionsCommunity distress is associated with lower PCS at 6 months after burn injury but no association with MCS was identified. Pre-injury HRQOL is associated with both PCS and MCS after injury. Further study of the factors underlying the relationship between community distress and physical functional recovery (e.g., access to rehabilitation services, availability of adaptations) is required to identify potential interventions.     

Impact of health-related quality of life on repeat protocol biopsy compliance on active surveillance for favorable prostate cancer: results from a prospective cohort in the PRIAS-JAPAN study

ObjectivesThis study aimed to evaluate how health-related quality of life (HRQOL) is related to repeat protocol biopsy compliance.Materials and methodsWe conducted a retrospective analysis using data from a prospective cohort in the Prostate Cancer Research International: Active Surveillance (PRIAS)-JAPAN study between January 2010 and August 2019. We used the Short Form 8 Health Survey (SF-8), as patient-reported outcomes, to assess HRQOL at AS enrollment and the first year of the protocol. The physical component summary (PCS) and mental component summary (MCS) were calculated from SF-8 questionnaires. The primary outcome was the evaluation of the association of HRQOL at enrollment on the first repeat biopsy compliance. The secondary outcome was the comparison of SF-8 scores during AS, stratified by repeat protocol biopsy compliance.ResultsOf 805 patients who proceeded to the first year of the protocol, the non-compliance rate was 15% (121 patients). In the adjusted model, lower MCS at enrollment was significantly associated with the first repeat protocol biopsy non-compliance (odds ratio [OR], 2.134; 95% confidence interval [CI], 1.031-4.42; P = 0.041) but not in lower PCS (OR, 0.667; 95% CI, 0.294-1.514; P = 0.333). All subscales of SF-8 were lower in the non-compliance group than in the compliance group at any point. MCS in the non-compliance group improved over time from the time of AS enrollment (2.34 increased, P = 0.152).ConclusionOur data suggest that lower MCS at AS enrollment using patient-reported outcomes was negatively associated with the first repeat protocol biopsy compliance. Our study may support the availability of a simple questionnaire to extract non-compliance.     

A simple risk score predicts poor quality of life and non-survival at 1 year follow-up in dialysis patients.

BACKGROUND: Quality of life (QoL) in end-stage renal disease patients has become an important focus of attention in evaluating dialysis. We studied risk factors of poor QoL at 1 year follow-up. METHODS: Of a baseline sample of 80 dialysis patients, we contacted 60 patients who were alive at 1 year follow-up. QoL data were obtained for 46 (76.7%) of these patients. QoL measured with the SF-36 [physical health component score (PCS) and mental health component score (MCS)] at 1 year-follow-up was predicted by means of multivariate regression analysis by data collected at baseline using INTERMED-an observer-rated method to assess biopsychosocial care needs-and several indicators for disease severity and comorbidity. RESULTS: The regression models explained 32% of the variance in PCS and 40% in MCS. INTERMED score (P < 0.01) was the only independent risk factor for low MCS, while for low PCS, diabetic comorbidity (P = 0.02) and age (P = 0.03) were independent risk factors. A simple risk score consisting of INTERMED > or =21, diabetic comorbidity and age > or =65 was significantly correlated with non-survival (P = 0.02) and with PCS (P < 0.01) and MCS (P < 0.01) in surviving patients, although not with hospital admissions during follow-up. CONCLUSIONS: A simple risk score based on INTERMED, age (> or =65) and comorbid diabetes (yes/no) can be used to detect patients at risk of poor QoL and non-survival at an early stage of treatment.

Health-related quality of life in Japanese men with localized prostate cancer: Assessment with the SF-8

Objectives:   To evaluate health related quality of life (HRQOL) using the Medical Outcomes Study 8-items Short Form Health Survey (SF-8) questionnaire in Japanese patients with early prostate cancer.
Methods:   A cross-sectional analysis was done in 457 patients with prostate cancer treated with radical prostatectomy, external beam radiotherapy, brachytherapy, androgen deprivation therapy, and watchful waiting or a combination these therapies. General HRQOL was measured using the Japanese version of the SF-8 questionnaire and disease-specific HRQOL was assessed using the Japanese version of the Extended Prostate Cancer Index Composite.
Results:   The external beam radiotherapy group reported significantly lower values for the physical health component summary score (PCS) in comparison to the radical prostatectomy and brachytherapy groups ( P  < 0.05). In the analysis of both the PCS and the mental health component summary score (MCS) over time after treatment, higher scores with time were found in the radical prostatectomy group. No significant change over time after androgen deprivation therapy in the PCS was found. In contrast, the MCS was found to deteriorate in the early period, showing a significant increase over time.
Conclusions:   SF-8 in combination with the Extended Prostate Cancer Index Composite has shown to be a helpful tool in the HRQOL assessment of Japanese patients treated for localized prostate cancer.     

Self-assessed physical and mental function of haemodialysis patients.

BACKGROUND: Physical (PCS) and mental (MCS) component summary scales of the Short Form 36 (SF-36) health survey are validated measures of quality of life (QOL) and functional status. We sought to evaluate the PCS and MCS in haemodialyis patients as compared to the general population and other chronic diseases. METHODS: A cohort of 134 haemodialysis patients (mean age 60.9+/-14.3 years, males 63.4%, Caucasians 66.4%) was followed from January 1996 to December 1998 (mean follow up 14.5+/-5.7 months). SF-36 questionnaires were administered every 3 months and PCS and MCS were calculated. Results were compared to the general population and other chronic diseases. Correlators of PCS and MCS, change in QOL over time, and the correlators of this change were determined. RESULTS: Mean PCS was 36.9+/-8.8 and mean MCS was 47+/-10.7. Compared to the general US population, these represent a decline of 8.7+/-0.8 for PCS (P<0.0001) and 2.7+/-0.8 for MCS (P<0.001). PCS and MCS in end-stage renal disease (ESRD) were lower than in most other chronic diseases studied. Univariate correlators of PCS in haemodialysis patients included age, male sex, haematocrit, serum albumin, and severity of comorbid cardiac and pulmonary illnesses. Multivariate analysis demonstrated independent correlators of PCS to be male sex, serum albumin and severity of comorbid cardiac and pulmonary diseases. Univariate as well as multivariate correlators of MCS included: serum albumin, KT/V(urea), and status living alone. A trend analysis revealed that both PCS and MCS tended to decline in the initial months of dialysis but stabilized over time. Status living alone was a significant predictor of improvement in MCS by univariate as well as multivariate analysis. CONCLUSIONS: Self assessed physical and mental health of haemodialysis patients is markedly diminished compared to the general population and other chronic diseases.     

Health-related quality-of-life changes after laparoscopic and open incisional hernia repair

BACKGROUND: The objective of this matched control study in patients suffering from incisional hernia was to compare laparoscopic open repair (LHR) with open hernia repair (OHR) in terms of long-term health-related quality of life (HRQL) according to the SF-36 Health Survey. METHODS: Twenty-four consecutive patients (18 male, six female; mean age, 55 years) prospectively underwent LHR using expanded polytetrafluoroethylene mesh. The second group, which was matched for age and gender, was subjected to OHR using large pore-sized, low-weight polypropylene meshes. Before and after surgery, HRQL was assessed by the SF-36 Health Survey, which measures eight different health-quality domains, and the SF-36 Physical (PCS) and Mental Component Summary (MCS) score. The SF-36 values were compared to the scores of age-stratified German population controls. RESULTS: The patients were reevaluated 16 months (range, 12-25) after LHR and 28 months (range, 18-52) after OHR, respectively. Before surgery, all of the eight health-quality domains as well as the PCS and MCS scores of both study groups were significantly lower than the corresponding scores of the age-stratified healthy German population. However, the OHR patients had significantly higher physical functioning and vitality scores than the LHR patients. After LHR and OHR, the scores for all eight SF-36 domains significantly increased but were still lower than those of the controls. The LHR patients were still worse than the norm population on both PCS and MCS scores, whereas OHR patients were worse only on PCS but not on MCS. In the long-term follow-up, none of the SF-36 Health Survey domains or the PCS and the MCS scores revealed significant differences between LHR and OHR patients. CONCLUSIONS: LHR was not different from OHR for selected indications that measure long-term outcome and HRQL. SF-36 appears to be an appropriate instrument to measure postoperative HRQL, showing responsiveness to changes in objective outcome measures.     

Different evaluations of the health related quality of life in dialysis patients

BACKGROUND: Sometimes patients on dialysis treatment cannot express their health-related quality of life (HRQoL); and therefore, it is necessary to use the assessment made by their carers. The purpose of this study was to evaluate the agreement between dialysis patients' HRQoL and the assessment made by their carers, and to investigate which variables were associated with the differences found. METHODS: Two hundred and twenty-two pairs of patients and carers were selected from 14 dialysis units. Patients' HRQoL was evaluated by the patients themselves and by their family carer (FAM), nurse (NUR) and physician (PH) using the Karnofsky scale (KS) and the EuroQOL5D (EQ5D) scale. Patients and their family carers answered the Medical Outcome Survey 36-Item Short Form Health Survey (SF-36), and the family carers answered the Zarit burden interview. Physicians scored the patients' comorbidity index and nurses evaluated the Barthel index (BI). RESULTS: The intraclass correlation coefficients (ICC) between the ratings provided by patients and their carers were: KS: 0.80(FAM), 0.76(NUR) and 0.62(PH); EQ5D: 0.42(FAM), 0.48(NUR) and 0.29(PH). The agreement between the EQ5D dimension scores varied from moderate for mobility and self-care to insignificant for pain and anxiety/depression. The variables associated to the size of the differences found were the Zarit burden interview score and the mental component score (MCS) (SF-36) of the carer, the physical component score (PCS) (SF-36), the BI score and patient comorbidity, and the physician's age and experience. CONCLUSIONS: Family carers and health care providers of dialysis patients are reasonably aware of the patient's level of function and well being and can be useful sources of proxy HRQoL information. Nevertheless, discrepancies can occur, depending in part on the different characteristics of patients and their caregivers.     

Poor quality of life is associated with increased mortality in maintenance hemodialysis patients: a prospective cohort study

Despite all developments in hemodialysis (HD), the mortality rate is still apparently higher than that in the general population, and worse health-related quality of life (HRQOL) is associated with increased mortality. We prospectively investigated the mortality status of HD patients during a five-year period and the association between mortality, HRQOL, laboratory parameters and clinical and sociodemographic characteristics at baseline. At the end of the five years, 293 patients out of 420 patients were still on HD treatment and 127 patients died. Those who died had a higher mean age, lower mean values of serum creatinine and albumin, higher prevalence of diabetes mellitus, received more HD twice weekly for less than 4 h in almost all HD sessions and had lower HRQOL than the survivors. We conclude that age, comorbidity, HD sessions lasting less than 4 h, malnutrition [hypoalbuminemia, low body mass index (BMI)] and lower physical component scores of SF-36 survey (PCS) were associated with higher risk of death in the HD population.     

Health-related quality of life among elderly Americans diagnosed with upper tract urothelial carcinoma

Background

Health-related quality of life (HRQOL) among elderly Americans diagnosed with upper tract urothelial cancer (UTUC) is unknown. We compared HRQOL in patients from before and after UTUC diagnosis and among different tumor stages after UTUC diagnosis using the Surveillance, Epidemiology, and End Results-Medicare Health Outcomes Survey database.
