Assessment of quality of life and its influence factors in maintenance hemodialysis patients

Objective To investigate the quality of life (QOL) of maintenance hemodialysis （MHD）patients and its influencing factors. Methods A total of 257 MHD patients in our hospital were recruited in this study. Clinical data of the patients were collected, and the QOL was assessed by MOS 36 item short form health survey(SF-36). Nutritional status of patients was evaluated by modified quantitative subjective global assessment (MQSGA). Univariate analysis of variance,pearson correlation analysis and multiple linear stepwise regression analysis were performed to determine the effect of related factors on QOL scores. Results The scores of all scales of SF - 36 evaluation in MHD patients were relatively lower than that of general population as reported before. Their physiological component summary (PCS) score decreased gradually as age grew, nevertheless, the mental component summary (MCS) score was highest in the group aged 41 - 60. The score was lower in patients with moderate to severe malnutrition or diabetic nephropathy when compared with other patients. Univariate analysis of variance also revealed that high SF-36 scores associated with higher education or income. Multivariate analysis indicated that PCS score and total SF-36 score of MHD patients were positively correlated with body mass index (BMI) and cholesterol, but negatively correlated with diabetic nephropathy, pulmonary artery systolic pressure and MQSGA score (all P＜0.05). There was positive correlation between MCS score and income,yet negative correlation between MCS score and MQSGA score (all P＜0.05). Conclusion MHD patients had relatively poor QOL. Primary diseases and nutritional status were probably the main influencing factors. Age, educated level, family income and pulmonary artery systolic pressure might also have effects on their QOL.

Correlation between quality of life and mineral metabolism in maintenance hemodialysis patients

Objective With multi-center investigation, to assess the life quality of patients with maintained hemodialysis (MHD) in Liaoning Province and to explore the relationship among the mineral metabolism, the life quality of the patients with MHD, and the repeated hospitalization within the latest three years. Methods 1192 patients with hemodialysis (at least 3 months) from January to March in 2015 at ten blood purification centers in Liaoning Province were selected for the cross - sectional survey. The Kidney Health-related Quality of Life (HRQOL) version 1.3 was used to evaluate the MHD patients' life quality. The total length of hospitalization was divided into four groups: 0 days, 3 to 15 days, 16 to 30 days and above 30 days. Results When serum calcium value ranged from 2.1 to 2.5 mmol/L, kidney - disease component summary (KDCS), mental component summary (MCS), physical component summary (PCS) and SF-36+KDCS corresponded to a higher value (P＜0.05). When serum phosphorus value ranged from 1.13 to 1.78 mmol/L, KDCS and SF-36+KDCS corresponded to a higher value (P＜0.05). When the calcium phosphorus product value ranged from 40.68 to 49.94, MCS corresponded to a higher value (P＜0.05). KDCS showed a linear correlation with age (P＜0.001), dialysis age, serum calcium (less than or equal to 2.5 mmol/L) (P＜0.05); PCS showed a linear correlation with age (P＜0.001) and dialysis age (P＜0.05); SF-36+KDCS showed a linear correlation with age (P＜0.001), and serum calcium (less than or equal to 2.5 mmol/L) (P＜0.05), while age and dialysis age were negatively correlated. The hospitalization days showed a linear correlation with age, dialysis age (P＜0.001) and serum phosphorus, calcium phosphorus product value (P＜0.05), while dialysis age and calcium phosphorus product value were negatively correlated. Among different groups of total hospitalization days in three years, age, hemodialysis age, serum calcium, serum phosphorus, calcium-phosphorus product value and quality of life values were all statistically significant (P＜0.05). Conclusions The life quality of patients with MHD were correlated with serum calcium, phosphorus, calcium and phosphorus product value, iPTH, dialysis age and age, while age and dialysis age were of negative correlation. The total number of hospitalization days in 3 years was closely linearly correlated with age and dialysis age, significantly correlated with serum phosphorus, calcium and phosphorus product value, while dialysis age, calcium and phosphorus product value were in a negative correlation. The total number of hospitalization in 3 years was correlated with the patients' age, dialysis age, serum calcium, serum phosphorus, calcium and phosphorus product value and quality of life.

Differences of prognosis in hemodialysis patients with different quality of life

Objective To compare the one-year survival rates of maintenance hemodialysis (HD) patients with different quality of life, and analyze related factors affecting the prognosis of patients. Methods Patients on hemodialysis for at least 3 months were enrolled. A short form 36 health survey questionnaire (SF-36) and Pittsburgh sleep quality index (PSQI) were used to evaluate the quality of life and quality of sleep. To observe one-year all-cause mortality and Cox regression model was used to analyze the factors associated with survival outcomes. Results A total of 159 patients undergoing hemodialysis were included, in which 136 patients completed the follow-up after one - year observation. The one - year survival rate in patients with both high physical component summary (PCS) and mental component summary (MCS) scores was significantly better than the patients with low PCS and MCS scores (P ﹤ 0.05). PCS, hemoglobin and serum albumin were the protection factors for HD patients. Conclusions Quality of life is strongly associated with prognosis in HD patients. Enhancing quality of life is of clinical significance in the improvement of HD patients' survival rate.     

Self-assessed quality of life in peritoneal dialysis patients.

BACKGROUND/AIMS: Studies comparing quality of life (QOL) between peritoneal and hemodialysis patients have yielded inconsistent results. Physical (PCS) and mental component summary (MCS) scales of Short Form 36 (SF-36) health survey are highly validated measures of self-assessed QOL. We sought to evaluate these indices in PD patients: (1) as measures of QOL, (2) predictors of QOL, (3) to study change in QOL over time, and (4) to compare QOL in PD vs. hemodialysis patients. METHODS: SF-36 questionnaires were administered every 3 months to patients over a 2-year period and PCS and MCS were calculated. Mean follow-up was 15.3 +/- 6.6 months for PD and 14.5 +/- 5.7 months for HD. RESULTS: Average PCS in PD (31.8 +/- 7.8) was lower than HD (36.9 +/- 9.8) (p < 0.02), while MCS was similar in the groups (p = NS). The prevalence of depression was 26.1% in PD and 25.4% in HD patients (p = NS). Serum albumin was the only significant predictor of PCS among PD patients and explained much of the decrease in PCS in them. The number of hospitalizations and in-hospital days were significantly lower for PD compared to HD patients (p < 0.05). PCS as well as MCS remained stable in both groups throughout the observation period. CONCLUSION: Self-assessed physical function is diminished, while mental function is similar in PD compared to HD patients. When corrected for serum albumin, this difference is eliminated. Over time, QOL in patients treated with PD remained stable.     

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.     

Perioperative myocardial infarction has negative impact on health-related quality of life following coronary artery bypass graft surgery.

OBJECTIVE: Perioperative myocardial infarction (PMI) is a well-described complication of coronary artery bypass grafting (CABG). Data on its effect on patients' subsequent health-related quality of life (QOL) and on other related consequences is deficient. The aim here was to evaluate in a prospective follow-up design the risk factors for and consequences of PMI and especially its possible impact on health-related QOL. METHODS: Comprehensive data, including preoperative risk profile, perioperative variables and postoperative morbidity up to discharge were collected of 501 CABG patients in the Heart Center of Tampere University Hospital and in all eighteen postoperative care hospitals. Eighty patients (16%) fulfilled ECG or cardiac enzyme criteria for PMI and they were compared to patients with no PMI. The RAND-36 Health Survey (RAND-36) was used as an indicator of QOL. The primary outcomes were change in physical component summary (PCS), mental component summary (MCS) and the eight dimensions of health-related QOL from the RAND-36. Symptomatic status was estimated according to New York Heart Association (NYHA) class. Assessments were made preoperatively and repeated 12 months later. RESULTS: Multivariate logistic regression analysis identified long cardiopulmonary bypass time (P=0.006) and high age (P=0.049) as independent predictors for PMI. Thirty-day mortality was adversely affected by PMI (6.3 vs 1.0%, P=0.001). In discharged patients, the occurrence of PMI did not affect 1-year survival adversely (98.7 vs 98.6%). The PMI patients showed significant (P<0.05) improvements in six of the eight dimensions of RAND-36, but they presented with a negative change in their 'general health' scores at the follow-up. All QOL scores improved significantly (P<0.001) among the patients without PMI. A highly significant (P<0.001) pattern of change was seen in the RAND-36 PCS and MCS scores in both groups although PMI patients showed significantly (P=0.002) smaller change in their PCS scores. Both groups showed similar freedom from anginal symptoms at 1 year (89.6 vs 90.1%) but in the PMI group later readmissions due to cardiac-related causes were more common (23 vs 10%, P=0.002). CONCLUSIONS: PMI increases 30-day mortality and affects also adversely on later health-related QOL following CABG.     

Assessment of long-term quality of life after laparoscopic and open surgery for Crohn''s disease

OBJECTIVE: Surgery for Crohn's disease (CD) is associated with a high recurrence rate and quality of life (QOL) in these patients is controversial. The aim of this study was to assess QOL in patients after laparoscopic and open surgery for CD by two different validated instruments, a generic nonspecific score and a specific gastrointestinal QOL index. PATIENTS AND METHODS: Patients with CD who underwent elective laparoscopic or open ileocaecal resection with primary anastomosis between 1992 and 2000 were followed for recurrence and surgery-related complications. QOL was assessed by the SF-36 Health Survey containing a mental (MCS) and a physical (PCS) component summary score and by the Gastrointestinal Quality of Life Index (GIQLI) developed by Eypasch. RESULTS: Thirty-seven patients with a mean age of 48.8 +/- 18.4 years including 23 females and 14 males were evaluated at a mean follow-up of 42.6 +/-25.8 months (minimum of 8 months). Twenty-one (57%) patients underwent laparoscopic resection and 16 (43%) open surgery. Both groups were well matched for age, gender, ASA class and body mass index. Fourteen (38%) patients developed recurrent disease and 3 (8%) had postoperative incisional hernias. Overall, QOL scores were 103 +/- 26.8 for the GIQLI, 47.2 +/- 11.8 for the PCS, and 49.2 +/- 11.5 for the MCS. The GIQLI correlated well with the SF36, correlation coefficient = 0.68 for GIQLI vs PCS (95% CI, 0.41,0.95) and 0.67 for GIQLI vs MCS (95%CI, 0.39, 0.95), respectively. When compared to the general US population, mean GIQLI scores (-13.8, P = 0.002) and mean PCS scores (-4.7, P = 0.001) were significantly lower in these patients than in healthy individuals. In a multivariate analysis of impact factors on QOL, recurrence within the follow-up period was the single significant determinant reducing the PCS (-35.1, P = 0.026) and the GIQLI (-36.1, P = 0.018). CONCLUSION: QOL is significantly reduced in patients with CD at long-term follow-up after both laparoscopic and open surgery. Recurrence is the only factor adversely affecting QOL of CD patients in remission irrespective of the operative technique applied.     

Assessment of frailty and its influence factors in maintenance hemodialysis patients

Objective To investigate the frailty in maintenance hemodialysis (MHD) patients and its influence factors. Methods A total of 127 adults undergoing hemodialysis from January 2015 and January 2016 in our center were recruited. Their clinical data and blood biochemical data were collected. Frailty was assessed using Fried's Frailty Phenotype. Quantification of coronary artery calcification (CACs) was determined by multi-slice spiral computed tomography (MSCT). According to the frailty scores, patients were divided into non-frailty, pro-frailty and frailty group. Their in clinical and biochemical index as well as CACs were compared. The correlations of frailty scores with above index were assessed by Spearman's correlation. Multiple logistic regression analysis was applied to evaluate the effect factors of frailty on MHD patients. Results Among 127 selected patients, 46(36.22%) patients without frailty, 45(35.43%) patients with pro-frailty, and 36(28.35%) patients with frailty. The age, diabetes, haemoglobin, albumin, pre-albumin, C-reactive protein, fibroblast growth factor 23 (FGF23), CACs and left ventricular end-diastolic dimension (LVEDD) of the 3 groups had statistical differences (all P＜0.05). The degrees of calcification among 3 groups were also different statistically (F=31.769, P＜0.001). In patients with MHD, frailty was positively correlated with age (r=0.545, P＜0.001), diabetes (r=0.236, P=0.008), C-reactive protein (r=0.245, P=0.006), FGF23 (r=0.189, P=0.034) and CACs (r=0.396, P＜0.001), while negatively correlated with haemoglobin (r=-0.257, P=0.004), albumin (r=-0.380, P＜0.001), pre-albumin (r=-0.313, P＜0.001). Age (OR=1.076), C-reactive protein (OR=1.176), albumin (OR=0.796) and artery calcification (OR=2.465) were independent influence factors for frailty in MHD patients (all P＜0.05). Conclusions The prevalence of frailty is high among MHD patients. Frailty is associated with age, C-reactive protein, albumin and artery calcification in MHD patients.

Differential changes in self-reported quality of life in elderly populations after diagnosis of a genitourinary malignancy

BackgroundThe time of cancer diagnosis is a major event during which quality of life (QOL) can be affected and represents a crucial time to identify patients at high risk of decline. We sought to compare the differential effects of the diagnosis of 3 major urologic malignancies on QOL.MethodsThe Surveillance, Epidemiology, and End Results–Medicare Health Outcomes Survey database was queried for patients who completed a QOL questionnaire (SF-36 or VR-12) before and after a diagnosis of bladder, kidney, or prostate cancer. Primary outcome measures were the mental component summary (MCS), and physical component summary (PCS) scores. Mixed effects linear regression was performed with cancer diagnosis as the primary variable of interest, with race and cardiovascular comorbidity status included as potentially confounding independent variables.ResultsThere were 3,258 patients with urologic cancers. Both MCS and PCS scores dropped after diagnosis in all disease states. Bladder and kidney cancer patients demonstrated the greatest decline in MCS score (-1.762 points, 95% CI-2.571 to -0.952, P < 0.001) and PCS score (-3.769 points, 95% CI-5.042 to -2.496, P < 0.001), respectively, after adjustment for potential confounders. By contrast, prostate cancer patients demonstrated the smallest decline in both domains. Race and cardiovascular comorbidity status were independently associated with QOL, with an association 2 to 3 times greater than that of cancer diagnosis.ConclusionsDiagnosis of a urologic cancer was associated with a decline in patient-reported QOL, particularly in those with bladder or kidney cancer. Changes in physical health were more prominent than in mental health. Race and cardiovascular comorbidity status influenced QOL domains to a greater extent than specific urologic cancer diagnosis.     

Investigation of vascular access in maintenance hemodialysis patients in Shanxi province

Objective To understand the current situation of vascular access selection in maintenance hemodialysis (MHD) patients in Shanxi Province, and analyze the factors affecting vascular access selection and risk factors of death in MHD patients. Methods MHD patients with clear vascular access information in Shanxi Province from January 2014 to December 2018 were enrolled in this study. The clinical data of patients were collected. The vascular access information of the selected candidates was clear. Multivariate logistic regression equation method was used to analyze the influencing factors of vascular access and the risk factors of death in MHD patients. Results Among the 10.236 patients with MHD, 9.130 patients (89.2%) selected autologous arteriovenous fistula (AVF) as vascular access, and 5.138 patients (50.2%) chose tunnel-free and non-polyester sheath central venous catheter (NCC) for the first dialysis. Multivariate logistic regression analysis showed that the primary disease of diabetic nephropathy (OR=0.517, 95%CI 0.281-0.796, P＜0.001) and dialysis age＜1 year (OR=0.483, 95%CI 0.219-0.811, P＜0.001) were the influencing factors of patients with MHD who did not to choose AVF. Primary disease of diabetic nephropathy (OR=2.242, 95% CI 1.816-2.828, P＜0.001), and using of central vein catheter (OR=1.785, 95% CI 1.237-2.579, P＜0.001) were independent risk factors of death in MHD patients. Conclusions AVF is the first choice for MHD patients in Shanxi Province. There is higher proportion of the use of NCC as the first dialysis vascular access. Primary disease of diabetic nephropathy and dialysis age＜1 year are the influencing factors for MHD patients not to choose AVF. Primary disease of diabetic nephropathy and use of central vein catheter may increase the risk of death in MHD patients.

Incidence of maintenance hemodialysis patients with fatigue and its related factors

Objective To investigate the incidence of fatigue in maintenance hemodialysis (MHD) patients and its related factors. Methods A total of 289 patients on MHD between January 2016 and March 2017 in hemodialysis centers of the First Affiliated Hospital of Xinjiang Medical University, Xinjiang Yili Kazak Autonomous Prefecture Friendship Hospital, and Yili Prefecture Hospital were enrolled. Internationally standard fatigue rating scale (FAI) was applied to assess the incidence of fatigue in MHD patients, and subjective comprehensive nutrition assessment (SGA) protein energy wasting rating scale was used to assess protein energy wasting (PEW) conditions. All patients were divided into the fatigue group and the non-fatigue group according to the FAI score. The clinical data and the blood biochemical indicators in two groups were compared. The risk factors of fatigue in MHD patients were analyzed by logistic regression method. Results The incidence of fatigue was 83.0% in MHD patients, and the rate of PEW was 62.6%. Blood total cholesterol in the fatigue group was lower than that of the non-fatigue group (P＜0.05). The difference between SGA scores of two groups had statistical significance (P＜0.001). Single factor logistic regression analysis results showed that higher SGA score (OR=1.312, 95%CI: 1.163-1.481, P＜0.001), lower blood total cholesterol (OR=0.661, 95%CI: 0.496-0.880, P=0.005) were risk factors of fatigue in MHD patients. Multivariable logistic regression analysis results showed that higher SGA score (OR=5.286, 95%CI: 2.078-13.442, P＜0.001) was an independent risk factor of fatigue in MHD patients. Conclusions The incidence of fatigue and PEW are high in MHD patients. PEW is an independent risk factor of fatigue in MHD patients.     

Multicenter study on the influencing factors of interdialysis blood pressure variability in maintenance hemodialysis patients

Objective To assess the influencing factors of interdialysis blood pressure variability (BPV) in maintenance hemodialysis (MHD) patients from Pearl River Delta, and provide clinically useful information for the prevention and treatment of BPV. Methods MHD patients in 10 hemodialysis centers from Pearl River Delta were enrolled and analyzed retrospectively. According to the quartile of interdialysis systolic blood pressure-coefficient of variation (SBP-CV), patients were divided into four groups, and clinical data, biochemical indicators and drug use were compared among 4 groups. Binary logistic regression analysis was used to analyze the associated factors of interdialysis BPV. Results A total of 1010 MHD patients (612 males and 398 females) with the age of (56.3±13.9) years were enrolled in this study. Their dialysis duration was (48.4±36.1) months, and the median of interdialysis SBP-CV was 8.07% (5.72%, 11.34%). According to the quartile of SBP-CV, the patients were divided into four groups: low BPV group (SBP-CV≤5.72%, 253 cases), middle BPV group (5.72%＜SBP-CV≤8.07%, 252 cases), high BPV group (8.07%＜SBP-CV≤11.34%, 253 cases) and extremely high BPV group (SBP-CV＞11.34%, 252 cases), and the dialysis duration, diabetes, ultrafiltration, interdialysis weight gain rate (IDWGR), serum calcium and the proportion of calcium channel antagonist used in the 4 groups were significantly different (all P＜0.05). Logistic multiple regression analysis showed that high IDWGR (OR=1.216, 95%CI 1.108-1.435, P＜0.001) was an independent risk factors for interdialysis BPV in MHD patients, while high ultrafiltration volume (OR=0.436, 95%CI 0.330-0.575, P＜0.001) and calcium channel antagonists used (OR=0.686, 95%CI 0.477-0.986, P=0.042) were independent protective factors. Conclusion High IDWGR is an independent risk factor for interdialysis BPV in MHD patients, while high ultrafiltration volume and calcium channel antagonists used are protective factors for interdialysis BPV in MHD patients.     

Quality of life in children with end-stage renal disease undergoing renal replacement therapy: a cross-sectional survey

Objective To evaluate the quality of life (QOL) of children with uremia who underwent renal replacement therapy (RRT) and identify the influencing factors for QOL in order to improve the QOL of children with uremia. Methods Children with ESRD who underwent dialysis or kidney transplantation (KT) at Children's Hospital of Fudan University between November 2016 and October 2017 were enrolled. The children and/or their parents completed and returned the Pediatric QOL Inventory Measurement Models (PedsQLTM) 4.0 questionnaire. Moreover, the clinical data of these children were collected. According to the way of RRT, children were divided into dialysis group and KT group. The differences of scores between two groups were compared. Multiple linear regression analysis was used to analyze the factors affecting the QOL of children. Results A total of 79 children undergoing RRT were enrolled. Among them, 48 cases in the dialysis group and 31 cases in the KT group. For children in KT group, the total PedsQL scores of child-self and parent-proxy assessment were higher than those in dialysis group (P＜0.05). The total scores for the QOL of child-self and parent-proxy assessment were roughly the same for KT children (P＞0.05). The total scores for the QOL of child-self and parent-proxy assessment were different for dialysis children (P=0.05). Short stature (height＜3th percentile) and elevated left ventricular mass index (LVMI) were the independent influencing factors for the QOL of child-self and parent-proxy assessment in children undergoing KT, respectively (B=12.162, t=2.681, P＜0.05; B=-0.240, t=-4.276, P＜0.01). Conclusions QOL was higher in children undergoing KT than those on dialysis. Short stature and elevated LVMI were the independent influencing factors for QOL in children undergoing KT.
