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.     

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.     

Patient-centered measures for achalasia

Background Various instruments may be used to measure health-related quality of life in patients with achalasia. Methods We administered four patient-centered measures used for evaluation of achalasia severity [an achalasia severity questionnaire we developed previously, an achalasia symptom checklist, the Gastrointestinal Quality-of-Life Index (GIQLI), and the Medical Outcomes Study 36-item Short-Form survey (SF-36)] to 25 subjects enrolled in a randomized controlled trial comparing pneumatic dilatation and laparoscopic Heller myotomy. We estimated correlations between the different measures. Results Twenty-five patients (13 male, 12 female) were studied; 12 were treated by pneumatic dilatation and 13 by laparoscopic myotomy. The average age of patients was 48.5 [range 25–69, standard deviation (SD) 13.7] years. Baseline scores demonstrated a substantial burden of impairment. The mean (SD) score on the achalasia severity measure [ranges from 0 (best) to 100 (worst)] was 62.3 (13.4). The mean (SD) symptom checklist score [ranges from 0 (best) to 36 (worst)] was 23.2 (6.6). The mean (SD) GIQLI [ranges from 0 (worst) to 144 (best)] was 77.04 (19.4). The SF-36 mean (SD) for the physical component score (PCS) was 45.29 (9.21) and the mean for the mental component score (MCS) was 37.61 (14.97). The achalasia severity measure correlated highly with the GIQLI (r = −0.57, p = 0.01), and the symptom checklist (r = 0.65, p = 0.004). The achalasia severity measure correlated well with the SF-36 PCS (r = −0.42, p = 0.039), but not with the MCS (r = −0.14, p = 0.501). Conclusion Subjects recruited to a randomized controlled trial of achalasia treatment demonstrated impairment in both generic quality-of-life and disease-specific measures. Scores on achalasia-specific measures correlated well with each other, but less well with measures of generic quality-of-life and mental health scales. Because of the multidimensional nature of achalasia, disease-specific measures should be combined with generic health measures for the best assessment of patient outcome.     

Sleep quality predicts quality of life and mortality risk in haemodialysis patients: results from the Dialysis Outcomes and Practice Patterns Study (DOPPS).

BACKGROUND: Poor sleep quality (SQ) affects many haemodialysis (HD) patients and could potentially predict their morbidity, mortality, quality of life (QOL) and patterns of medication use. METHODS: Data on SQ were collected from 11,351 patients in 308 dialysis units in seven countries in the Dialysis Outcomes and Practice Patterns Study (DOPPS) between 1996 and 2001 through a patient self-reported SQ scale, ranging from 0 (worst) to 10 (best). A score of <6 reflected poor SQ. Sleep disturbance was also assessed by self-reported daytime sleepiness, feeling drained and nocturnal awakening. Logistic and multiple linear regression were used to assess predictors of SQ and associations with QOL. Cox regression examined associations with mortality. Analyses accounted for case-mix, facility clustering and country. RESULTS: Nearly half (49%) of patients experienced poor SQ. Mean SQ scores varied by country, ranging from 4.9 in Germany to 6.5 in Japan. Patients with poor SQ were more likely to be prescribed antihistamines, antidepressants, anti-inflammatories, narcotics, gastrointestinal (GI) medications, anti-asthmatics or hypnotics. Physical exercise at least once a week (vs < once a week) was associated with lower odds of poor SQ (AOR = 0.55-0.85, P < 0.05). Poorer SQ was associated with significantly lower mental and physical component summary (MCS/PCS) scores (MCS scores 1.9-13.2 points lower and PCS scores 1.5-7.7 points lower when SQ scores were <10 vs 10). The RR of mortality was 16% higher for HD patients with poor SQ. CONCLUSIONS: Poor SQ is common among HD patients in DOPPS countries and is independently associated with several QOL indices, medication use patterns and mortality. Assessment and management of SQ should be an important component of care.     

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.     

Application of KDQOL-SFTM 1.3 version in evaluating quality of life of maintenance hemodialysis patients in multiple centers

Objective To understand the quality of life (QOL) and its influencing factors in maintenance hemodialysis patients (hemodialysis maintenance, MHD), and to provide theoretical basis for improving QOL of patients. Methods A cross-sectional study was conducted in the blood purification centre in 8 hospitals of Hefei, and patients clinical data were collected. KDQOL-SF self-administered questionnaire was applied to assess the health related quality of life (HRQL) of patients and to analyze the factors influencing the QOL. Results The QOL of MHD patients in Hefei City was better compared with previous similar research results. Generally speaking, gender (male), education degree and household income were positive correlated with QOL scores (P＜0.05), and the scores of primary disease of patients with diabetic nephropathy or drugs were lower (P＜0.05) in physiological component summary (PCS), mental component summary (MCS), SF-36 and KDTA. Charlson comorbidity index (CCI) was negatively correlated with the MCS scores, PCS scores and SF scores (P＜0.05), and patients' occupational and medical insurance had impacts on MCS and KDTA score (P＜0.05). Conclusions The QOL of MHD patients are affected by many factors, and the CCI and cultural level are possible independent influencing factors. In addition, gender, household income per capita, primary disease, occupation, medical insurance also have certain influence.     

Should aggregate scores of the Medical Outcomes Study 36-item Short Form Health Survey be used to assess quality of life in knee and hip osteoarthritis? A national survey in primary care

OBJECTIVE: To assess the relevance of using the aggregate physical component score (PCS) and mental component score (MCS) of the Medical Outcomes Study 36-item Short Form Health Survey (SF-36) for patients with knee and hip osteoarthritis (OA). METHODS: We conducted a cross-sectional national survey in a primary care setting in France. A total of 1474 general practitioners enrolled 4183 patients with hip or knee OA. Construct validity of PCS and MCS was assessed by convergent and divergent validity and factor analysis. RESULTS: Records of 4133 patients (98.8%) were analyzed (2540 knee, 1593 hip OA). PCS mean scores were 32.0+/-8.4 and 31.8+/-8.4 and MCS scores 47.1+/-11.0 and 46.8+/-11.1, for knee and hip OA, respectively. Acceptable convergent and divergent validity was observed, and correlation between PCS and MCS mean scores was low (r=0.14). However, factor analysis performed on the eight subscale scores failed to support the use of PCS and MCS aggregate scores. It extracted two factors which were similar for both OA types and differed from the a priori stratification. Scores for two subscales usually attributed to MCS - emotional role and social functioning - were shared between factors, and scores for another subscale - general health perception - usually belonging to the PCS was in the mental component factor. CONCLUSIONS: Our results suggest that aggregate scores from the PCS and MCS of the SF-36 as they are currently defined may not be optimal for used in hip and knee OA patients to assess health-related quality of life.     

Prospective assessment of health-related quality of life after endovascular repair of pararenal and thoracoabdominal aortic aneurysms using fenestrated-branched endografts

ObjectiveThe objective of this study was to investigate changes in health-related quality of life (QOL) in patients treated for pararenal aortic aneurysms (PAAs) and thoracoabdominal aortic aneurysms (TAAAs) with fenestrated-branched endovascular aneurysm repair (F-BEVAR).MethodsA total of 159 consecutive patients (70% male; mean age, 75 ± 7 years) were enrolled in a prospective, nonrandomized single-center study using manufactured F-BEVAR (2013-2016). All patients were observed for at least 12 months (mean follow-up time, 27 ± 12 months). Patients' health-related QOL was assessed using the 36-Item Short Form Health Survey questionnaire at baseline (N = 159), 6 to 8 weeks (n = 136), 6 months (n = 129), and 12 months (n = 123). Physical component scores (PCSs) and mental component scores (MCSs) were compared with historical results of patients enrolled in the endovascular aneurysm repair (EVAR) 1 trial who were treated by standard EVAR for simple infrarenal abdominal aortic aneurysms.ResultsThere were 57 patients with PAAs and 102 patients with TAAAs (50 extent IV and 52 extent I-III TAAAs). There were no 30-day deaths, in-hospital deaths, conversions to open surgery, or aorta-related deaths. Survival was 96% at 1 year and 87% at 2 years. Major adverse events occurred in 18% of patients, and 1-year reintervention rate was 14%. There were no statistically significant differences between the groups in 30-day outcomes. Patients treated for TAAAs had lower baseline scores compared with those treated for PAAs (P < .05). PCS declined significantly 6 to 8 weeks after F-BEVAR in both groups and returned to baseline values at 12 months in the PAA group but not in the TAAA group. Patients with TAAAs had significantly lower PCSs at 12 months compared with those with PAAs (P < .001). There was no decline in mean MCS. Major adverse events were associated with decline in PCS assessed at 6 to 8 weeks (P = .021) but not in the subsequent evaluations. Reinterventions had no effect on PCS or MCS. Overall, patients treated by F-BEVAR had similar changes in QOL measures as those who underwent standard EVAR in the EVAR 1 trial, except for lower PCS in TAAA patients at 12 months.ConclusionsPatients treated for TAAAs had lower scores at baseline in their physical aspect of health-related QOL. F-BEVAR was associated with significant decline in PCSs in both groups, which improved after 2 months and returned to baseline values at 12 months in patients with PAAs but not in those with TAAAs. Patients treated for PAAs had similar changes in QOL compared with those treated for infrarenal aortic aneurysms with standard EVAR.     

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.     

Laparoscopic Nissen fundoplication improves quality of life in patients with atypical symptoms of gastroesophageal reflux

Laparoscopic Nissen fundoplication has been shown to improve overall quality of life (QOL) in patients with gastroesophageal reflux, but most studies have not addressed patients with atypical symptoms. We investigated the effect of laparoscopic Nissen fundoplication on QOL using the Gastrointestinal Quality of Life Index (GIQLI) survey modified to address both typical (heartburn, regurgitation, dysphagia) and atypical (hoarse voice, chronic cough, adult-onset asthma, vocal cord polyps) symptoms. One-hundred forty-eight patients underwent laparoscopic Nissen fundoplication for gastroesophageal reflux disease (GERD) at UCLA Medical Center from January 1, 1995 to May 1, 2002. Surveys evaluating pre- and postoperative QOL were administered after surgery: 55 per cent of patients responded (82/148). Forty-eight per cent of all patients (72/148) had atypical symptoms. Perioperative morbidity and mortality were 8.8 per cent and 0.7 per cent, respectively. Mean length of postoperative stay was 2.96 +/- 1.5 days. Mean follow-up for the entire cohort was 18.5 months. Postoperative dysphagia not present before surgery occurred in 4.7 per cent of patients. Eighty per cent of patients were medication-free following surgery. QOL scores for all participants increased significantly from 52.5 +/- 15.3 preoperatively to 72.0 +/- 14.9 postoperatively (P < 0.0001). Patients with atypical symptoms or typical symptoms alone showed significant mean QOL score increases from 48.3 +/- 17.6 preoperatively to 71 +/- 15.7 postoperatively (P < 0.0001) and from 55.7 +/- 12.6 to 72.8 +/- 14.4 (P < 0.0001), respectively. Laparoscopic Nissen fundoplication can effectively improve overall QOL for patients with GERD. Patients with atypical GERD symptoms can experience increases in QOL similar to those with only typical gastrointestinal symptoms.

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.     

Comparison of patient-centered outcomes after laparoscopic Nissen fundoplication for gastroesophageal reflux disease or paraesophageal hernia

Background Patients undergoing laparoscopic Nissen fundoplication (LNF) with paraesophageal hernias (PEH) are not only older and less healthy than those with gastroesophageal reflux disease (GERD), but in addition the repair is more complicated. We evaluated whether outcomes relating to GERD symptoms and quality of life (QOL) were impacted by the presence of PEH. Methods Prospectively entered data from 149 patients (109 GERD and 40 PEH) were evaluated prior to and one year after LNF with standardized and validated symptoms scores. Scores for heartburn, dysphagia, disease-specific QOL (GERD-HRQL), and general health-related QOL (SF-12 physical and mental component scores) were compared between patients undergoing LNF for PEH or for GERD alone, at baseline and one year after surgery. p < 0.05 was considered statistically significant. Results Preoperative data for GERD-HRQL, heartburn, and dysphagia were available for 134 patients, with 96% one-year follow-up. SF-12 data were collected for 98 patients with 100% follow-up. PEH patients were older and had greater comorbidity. Preoperative GERD-HRQL and heartburn were significantly worse in the GERD group. One year after surgery, both GERD and PEH patients showed significant improvement in GERD-HRQL, heartburn and dysphagia scores, with no difference in any of these disease or symptom measures between the two study groups. Postoperative PCS and MCS scores showed improvement in GERD patients, while PEH patient scores remained at or below the population mean. Conclusions LNF is equally effective as an antireflux procedure in both GERD and PEH patients, prevents symptoms of reflux in PEH patients that have none preoperatively, and does not increase dysphagia in either group. Despite the increased complexity of the procedure, LNF provides an effective control of reflux symptoms in patients undergoing PEH repair.

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.     

Quality of life and predictors of long-term outcome in patients undergoing open Nissen fundoplication for chronic gastroesophageal reflux

BACKGROUND: Long-term outcome of antireflux operations as well as pre- and postoperative parameters able to predict their clinical results are still controversial. The aim of the present study was to evaluate long-term quality of life of patients undergoing open fundoplication for chronic GERD and to investigate pre- and early postoperative functional parameters possibly related to persistence or recurrence of symptoms. METHODS: A cohort of 25 patients who underwent open Nissen fundoplications was reviewed for an evaluation of long-term residual symptoms and quality of life at an average follow-up of more than 10 years. Clinical evaluation was performed by using a symptom-specific score (DeMeester's score), 3 health-related quality of life scores, a GERD-specific (GERD-HRQL score) score, and 2 generic scores (SF-36) evaluating physical and psychological well-being. Subjective satisfaction grade of the patients was also investigated. In addition, a univariate analysis is provided, according to the long-term presence or absence of residual symptoms (120.6-month follow-up), taking into account pre- and postoperative (6-month follow-up) data of endoscopy, 24-hour pH monitoring, stationary manometry, and gastric-emptying test. RESULTS: Persistence or recurrence of GERD-specific symptoms (heartburn and regurgitation) were reported by 8 patients (32%); 2 patients (8%) were reoperated on for persistent dysphagia, whereas 17 patients (68%) were asymptomatic. GERD-HRQL and SF-36 scores displayed significant postoperative improvement, which continued in long-term follow-up. Twenty patients (80%) had repeat fundoplication. Among tested parameters, only postoperative mean supine esophageal clearance and gastric emptying half-time, although on average improved significantly after the antireflux procedure, differed significantly in long-term asymptomatic and symptomatic subgroups. In long-term asymptomatic patients, postoperative (6 month) mean supine esophageal clearance was 0.8 +/- 0.3 minutes (P = .011) and 2.4 +/- 0.2 minutes in symptomatic patients. Postoperative (6 month) mean gastric emptying half-time of long-term asymptomatic patients was 93.3 +/- 8.9 minutes, whereas in symptomatic patients it was 127.5 +/- 14.3 minutes (P = .047). CONCLUSIONS: Patients undergoing Nissen fundoplication had a satisfactory long-term quality of life. Clinical results did not deteriorate over time and showed to be related to postoperative esophageal clearance and gastric emptying, which could be regarded as early postoperative predictors of long-term clinical outcome.     

Predictors of early quality-of-life improvement after laparoscopic gastric bypass surgery

BACKGROUND: Quality of life is getting more attention in the medical literature. Treatment outcomes are now gauged by their effect on quality of life (QOL), along with their direct effect on diseases they are targeting. Similarly, in obesity, consensus has been reached on the importance of QOL as an independent outcome measure for obesity surgery along with weight loss and comorbidity. Therefore, the aim of this study was to assess the impact of patient demographics and comorbidities on short-term QOL improvement after laparoscopic gastric bypass (LGB) surgery. METHODS: The change in QOL after LGB was assessed in 171 patients (147 women, 24 men; mean age, 43.1 y) using the Short-Form-36 (SF-36) questionnaire. Multivariate logistic regression analysis was used to identify patients' demographics and comorbidities predictive of major QOL improvement. RESULTS: Body mass index decreased significantly at 3 months (48.5 +/- 5.8 to 38.4 +/- 5.4 kg/m2; P < .001) with excess weight loss of 37.4% +/- 9.2%. The SF-36 follow-up evaluation showed significant improvement (44.2 +/- 15.7 to 78.6 +/- 15.5; P < .001). A significant inverse correlation was found between QOL (before and after bypass) and the number of comorbidities (r = .29, P = .001; R = .22, P = .005; respectively), but the magnitude of QOL change did not correlate with the number of comorbidities (P = .5). When the entire cohort of patients was dichotomized according to their magnitude of change in SF-36 scores, the univariate analysis showed that the group of patients with no improvement or minor improvement in their SF-36 was characterized by a higher percentage of male sex and a lower prevalence of diabetes. These 2 preoperative factors remained statistically significant in the multivariate analysis. Preoperative diagnosis of type 2 diabetes increased the likelihood of major improvement in QOL after LGB by 6.2 times, whereas being a woman increased this likelihood by 16.1 times. CONCLUSIONS: Significant weight loss was achieved as early as 3 months after LGB, causing substantial improvement in QOL in more than 95% of patients. Women with type 2 diabetes have the highest odds to achieve a major QOL improvement after LGB and therefore they should represent the ideal target population for surgical weight loss programs.     

Is repairing giant hiatal hernia in patients over 80 worth the risk?

Patients with giant hiatal hernia (GHH) are often symptomatic and have significantly reduced quality of life (QoL). Advanced age is a predictor of increased morbidity and mortality in open hiatal surgery, however, outcomes of laparoscopic surgery in patients over the age of 80 are limited to case reports and small case series.Data was extracted from a prospectively maintained database. Consecutive patients over the age of 80 with GHH that have undergone surgery were included. Peri-operative mortality, complications, recurrence rates, use of acid suppressive medication and QoL was analysed. Search of Ryerson index was performed to determined post-operative survival.Inclusion criteria were met by 89 patients. Mean age was 84 (80–93). The mean volume of herniated stomach was 70.9% range 30–100%; SD 27.25). There was one death in this cohort on day 30 from myocardial infarction and one mediastinal collection requiring percutaneous radiological drainage and antibiotics. There were no other major complications (Clavien-Dindo Grade III-IV). Mean post-operative survival was 74.5 months (SD 47.8). GIQLI was reduced pre-operatively (mean 91.8; SD 19.4). There was significant improvement in GIQLI scores at early (mean 101.45; SD 21.2) and late (mean 106.7; SD 19.2) post-operative follow-up (p = 0.005). Pre-operative Visick scores (mean 2.92; SD 0.98) have improved significantly in early (mean 1.94; SD 0.97; p = 0.000) and late (mean 2.03; SD 0.99; p = 0.001) post-operative periods. Satisfaction with surgery was 97% during early and 93.3% during late post-operative follow up.Laparoscopic repair of GHH in appropriately selected elderly patients is safe and results in significant improvement in quality of life.     

Quality of life on chronic dialysis: comparison between haemodialysis and peritoneal dialysis.

BACKGROUND: Quality of life (QOL) assessment in patients on chronic haemodialysis (HD) or peritoneal dialysis (PD) has only rarely been carried out with the generic Euroqol-5D questionnaire. METHODS: All chronic HD and PD patients in the 19 centres of western Switzerland were requested to fill in the validated Euroqol-5D generic QOL questionnaire, assessing health status in five dimensions and on a visual analogue scale, allowing computation of a predicted QOL value, to be compared with the value measured on the visual analogue scale. RESULTS: Of the 558 questionnaires distributed to chronic HD patients, 455 were returned (response rate 82%). Fifty of 64 PD patients (78%) returned the questionnaire. The two groups were similar in age, gender and duration of dialysis treatment. Mean QOL was rated at 60+/-18% for HD and 61+/-19% for PD, for a mean predicted QOL value of 62+/-30 and 58+/-32% respectively. Results of the five dimensions were similar in both groups, except for a greater restriction in usual activities for PD patients (P = 0.007). The highest scores were recorded for self-care, with 71% HD and 74% PD patients reporting no limitation, and the lowest scores for usual activities, with 14% HD and 23% PD patients reporting severe limitation. Experiencing pain/discomfort (for HD and PD) or anxiety/depression (for PD) had the highest impact on QOL. CONCLUSIONS: QOL was equally diminished in HD and PD patients. The questionnaire was well accepted and performed well. Improvement could be achievable in both groups if pain/discomfort and anxiety/depression could be more effectively treated.     

Organ quality and quality of life after liver transplantation

Not only is there a limited supply of organs for liver transplantation, but the quality of the available organs is not uniform. Risk factors such as donor age and cause of death are known to predict graft failure, but their impact on the recipient's quality of life (QOL) has not been reported. We sent a QOL survey to 299 adults at our institution who had received a liver transplant 1 to 7 years before the study. For the 171 patients (57%) who completed the Medical Outcomes Study Short Form 36 (SF-36), the mean Physical Composite Score (PCS) and the mean Mental Composite Score (MCS) were 61 and 66, respectively; the highest scores were for the Social Functioning subscale, and the lowest scores were for the Role Functioning/Physical and Energy/Fatigue subscales. The mean donor risk index (DRI) of the organs that the subjects received was 1.4 (range = 0.8-2.4). There was no correlation between the SF-36 scores and the DRI [there were changes of -4.8 and -2.8 in the PCS and MCS per unit increase in the DRI (P = 0.4 and 0.6, respectively)], even though we controlled for potential confounders such as age, sex, hospitalization before transplantation, the Model for End-Stage Liver Disease score at transplantation, years since transplantation, previous transplantation, and the Charlson comorbidity index. In conclusion, we found no association between organ quality and QOL after liver transplantation. If this finding is confirmed in prospective, multicenter studies, it will be useful in counseling patients about the decision to accept or not accept high-risk organ offers.     

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.
