Long-term outcome and health-related quality of life after laparoscopic and open colectomy for benign disease

Background: The benefits of laparoscopic colectomy (LC) vs open colectomy (OC) for the treatment of benign disease have not yet been clearly demonstrated with regard to long-term consequences and health-related quality of life (HRQL). The aim of this study was to compare LC and OC in terms of outcome and HRQL and to determine whether a generic nonspecific instrument for HRQL assessment is valid in postoperative follow-up. Methods: Forty-nine patients who underwent LC for elective right hemicolectomy (RH) or sigmoid resection (SR) for benign polyps or uncomplicated diverticular disease between 1992 and 2000 were evaluated and compared to 50 controls treated by OC in the same period. All patients were evaluated by postal questionnaire to determine recurrence rates and surgery-related complications. HRQL was assessed by the SF-36 Physical and Mental Component Summary Score (PCS, MCS) and by the SF-36 Health Survey, which measures eight different health-quality domains, including physical and social functioning (PF, SF), general health perception (GH), physical and emotional role limitations (RP, RE), body pain (BP), vitality (VT), and mental health (MH). Results: The LC and OC patients were similar in age, gender, body mass index (BMI), American Society of Anesthesiologists (ASA) classification, and diagnosis. There were significant differences between the two groups in resection type (26 RH:23 SR in LC vs 16 RH:34 SR in OC, p = 0.03) and length of follow-up (median, 39 and 53.5 months, respectively, p = 0.04), but neither parameter was predictive of the main SF-36 scores (PCS and MCS). There were no differences between the groups in recurrence rates (8% in LC vs 11% in OC) or surgery-related complications, including incisional hernias (16.3% in LC vs 17% in OC) and small bowel obstructions (2% in LC vs 10.4% in OC). None of the eight SF-36 Health Survey domains or the PCS or MCS scores showed significant differences between LC and OC patients in HRQL. However, occurrence of hernia after surgery was predictive of lower SF-36 scores, specifically in PF (p = 0.047), GH (p = 0.045), SF (p = 0.047), MH (p = 0.041), and MCS (p = 0.037). In addition, small bowel obstruction was significantly associated with lower scores in BP (p = 0.008), GH (p = 0.008), SF (p = 0.013), RE (p = 0.026), MH (p = 0.003), and MCS (p = 0.003). Conclusion: LC was not different from OC 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.

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.     

Inguinal hernioplasty improves the quality of life in patients with cirrhosis

BACKGROUND: The optimal management of symptomatic inguinal hernia (SIH) in cirrhotics is still undefined. Both hernia and cirrhosis impair quality of life (QOL). The aim of this study was to evaluate QOL by a Short Form-36 (SF-36) questionnaire in cirrhotic patients undergoing inguinal hernioplasty. METHODS: Thirty-two cirrhotic patients undergoing inguinal hernioplasty were evaluated. They were classified according to Child's class and to the absence or presence of refractory ascites. The SF-36 questionnaire was administered the day before and 6 months after surgery. Global analyses of the 8 domains of SF-36 and of 2 comprehensive indexes of SF-36, Physical Component Summary (PCS) and Mental Component Summary (MCS), were performed. RESULTS: Lichtenstein hernioplasty for SIH originated no major complications. All 8 domains of SF-36 and MCS and PCS scores improved remarkably after hernioplasty especially in patients in Child's class C and/or with refractory ascites. CONCLUSIONS: Inguinal hernioplasty for SIH in patients with cirrhosis is a safe procedure. The improvement of QOL represents a clear cut indication for elective hernia repair.     

Assessment of health-related quality of life in spine treatment: conversion from SF-36 to VR-12

Background Context

Health-related quality-of-life outcomes have been collected with the Medical Outcomes Study (MOS) Short Form 36 (SF-36) survey. Boston University School of Public Health has developed algorithms for the conversion of SF-36 to Veterans RAND 12-Item Health Survey (VR-12) Physical Component Summary (PCS) and Mental Component Summary (MCS) scores.

Health-related quality of life in morbidly obese patients: effect of gastric bypass surgery

Background: The effect of gastric bypass on the health-related quality of life (HRQoL) of morbidly obese patients was investigated in a cross-sectional study. Methods: A postoperative group of 78 patients on average 13.8 years after gastric bypass was compared with a preoperative control group of 110 patients. The SF-36 was used to assess HRQoL. In preoperative patients, the SF-36 was self-administered, while in the postoperative group, telephone interviews were conducted. In the postoperative sample, multiple stepwise linear regression analyses were carried out to examine putative predictors of the physical (PCS) and the mental (MCS) composite scores of the SF-36. Results: Significant differences between the preand postoperative group were found for all subscales except Mental Health, in favor of the postoperative group. On average 13.8 years after gastric bypass, most of the sub-scales were similar to the US norm values. However, the Bodily Pain and the overall Physical Composite scale (PCS) scores were lower (more impaired) in the postoperative group compared with the US norms. Female patients, patients who were hospitalized since the surgery, and those who had lost less weight had more impaired values on the PCS and patients who reported binge-eating disorder (BED) at follow-up had more impaired values on the Mental Composite Scale (MCS) of the SF-36. Conclusion: HRQoL was significantly better in postoperative gastric bypass patients in comparison to a sample of preoperative patients. However, HRQoL, specifically the physical domain of the SF-36, was more impaired in long-term follow-up patients compared with US norm values. The reoccurrence of BED after surgery negatively influenced the mental domain of the SF-36.     

Correlation of SF-12 and SF-36 in a trauma population

BACKGROUND: The SF-36 is a commonly used general measure of health-related quality of life (QoL). The SF-12 is a related tool with less response burden, but its performance in a general trauma population is unknown. Hypothesis: The SF-12 would provide similar QoL information to the SF-36 in blunt trauma patients. METHODS: Adults with nonneurological blunt injury were prospectively enrolled. Demographic, injury, and socioeconomic data were collected. Patients were assessed with functional and psychologic questionnaires 1 and 6 months after injury. Physical (PCS) and mental (MCS) component scores of the SF-36 and SF-12 were compared using Pearson's correlation coefficient. Linear regression identified factors associated with the SF-12 and SF-36 PCS and MCS. Responsiveness to change was assessed using the standardized response mean. RESULTS: Correlation of the PCS was 0.924 and MCS was 0.925 (both P < 0.001). QoL remained below population norms at 6 months. PCS was moderately responsive to change and was equivalent using either the SF-12 or the SF-36. MCS was not responsive to change using either tool. At both time points, at least 25% of patients with normal SF-12 PCS or MCS had SF-36 subscale scores significantly below the normal population. CONCLUSIONS: The SF-12 can be used to assess QoL in trauma patients. The lack of responsiveness to change of the MCS suggests other methods may be necessary to fully evaluate mental QoL. Summary scores may not be sufficient to fully assess QoL in this population. Combining the SF-12 with measures to assess psychosocial variables should be further investigated.     

The association between post-concussion symptoms and health-related quality of life in patients with mild traumatic brain injury

A subset of mild traumatic brain injury (mTBI) patients experience post-concussion symptoms. When a cluster of post-concussion symptoms persists for over three months, it is referred to as post-concussion syndrome (PCS). Little is known about the association between PCS and Health-Related Quality of Life (HRQoL) after mTBI. The aims of this study were to assess the implications of PCS on HRQoL six months after mTBI and the relationship between PCS and HRQoL domains. A prospective observational cohort study was conducted among a sample of mTBI patients. Follow-up postal questionnaires at six months after emergency department (ED) admission included socio-demographic information, the Rivermead Post-Concussion Symptoms Questionnaire (RPQ), and HRQoL measured with the 36-item Short-Form Health Survey (SF-36) and the Perceived Quality of Life Scale (PQoL). In total, 731 mTBI patients were included, of whom 38.7% were classified as suffering from PCS. Patients with PCS had significantly lower scores on all SF-36 domains, lower physical and mental component summary scores and lower mean PQoL scores compared to patients without PCS. All items of the RPQ were negatively correlated to all SF-36 domains and PQoL subscale scores, indicating that reporting problems on any of the RPQ symptoms was associated with a decrease on different aspects of an individuals’ HRQoL. To conclude, PCS is common following mTBI and patients with PCS have a considerably lower HRQoL. A better understanding of the relationship between PCS and HRQoL and possible mediating factors in this relationship could improve intervention strategies, the recovery process for mTBI patients and benchmarking.     

Evaluation of long term health-related quality of life in extensive burns: a 12-year experience in a burn center

Objectives

We sought to evaluate the long term health-related quality of life (HRQOL) in patients survived severely extensive burn and identify their clinical predicting factors correlated with HRQOL.

Methods

A cross-sectional study was conducted in 20 patients survived more than 2 years with extensive burn involving ≥70% total body surface area (TBSA) between 1997 and 2009 in a burn center in Shanghai. Short Form-36 Medical Outcomes Survey (SF-36), Brief Version of Burn Specific Health Scale (BSHS-B) and Michigan Hand Outcome Questionnaire (MHQ) were used for the present evaluation. SF-36 scores were compared with a healthy Chinese population, and linear correlation analysis was performed to screen the clinical relating factors predicting physical and mental component summary (PCS and MCS) scores from SF-36.

Results

HRQOL scores from SF-36 were significantly lower in the domains of physical functioning, role limitations due to physical problems, pain, social functioning and role limitations due to emotional problems compared with population norms. Multiple linear regression analysis demonstrated that only return to work (RTW) predicted improved PCS. While age at injury, facial burns, skin grafting and length of hospital stay were correlated with MCS. Work, body image and heat sensitivity obtained the lowest BSHS-B scores in all 9 domains. Improvements of HRQOL could still be seen in BSHS-B scores in domains of simple abilities, hand function, work and affect even after a quite long interval between burns and testing. Hand function of extensive burn patients obtained relatively poor MHQ scores, especially in those without RTW.

Conclusions

Patients with extensive burns have a poorer quality of life compared with that of general population. Relatively poor physical and psychological problems still exist even after a long period. Meanwhile, a trend of gradual improvements was noted. This information will aid clinicians in decision-making of comprehensive systematic regimens for long term rehabilitation and psychosocial treatment.     

A comparison of laparoscopic and open hernia repair as a day surgical procedure

To evaluate the merits of laparoscopic inguinal hernia repair (LHR) compared to conventional open hernia repair (OHR) a randomized study has been conducted.All patients were day surgical cases, of which 44 were randomized to a standardized OHR under local anesthetic (LA) and 42 to an LHR under general anesthesia (GA). Fifteen LHR patients had bilateral repairs.Operative time for OHR was 30.5 min, for unilateral LHR 35 min, and for bilateral LHR 60 min. OHR patients were discharged after a median of 134.5 min, which was significantly shorter than LHR patients, whose median discharge was 225 min (P<0.01). Pain scores, activity levels, analgesia requirements, and time taken to return to work were not significantly different following surgery in either group (P<0.05). There have been two recurrent hernias and one small bowel obstruction in the LHR group.We conclude that both repairs can be successfully performed as day surgical procedures. The added cost of LHR at this stage does not warrant its widespread use in unilateral hernia repairs. Which procedure is adopted should be individualized; however, patients with bilateral hernias on presentation can be successfully managed as day cases, obviating the need for hospitalization or two operations.     

Five-year Changes in Health-Related Quality of Life after Biliopancreatic Diversion with Duodenal Switch

Background

Long-term data of health-related quality of life (HRQL) after biliopancreatic diversion with duodenal switch (BPDDS) procedure are lacking. The aim of this study was to evaluate changes in HRQL from baseline to 5 years after BPDDS.

Methods

Fifty morbidly obese patients were followed for 5 years after BPDDS procedure. The sample consisted of 27 women and 23 men, the mean age was 37.8 years, and the mean body mass index (BMI) was 51.7 units. HRQL was measured with the Short Form 36 questionnaire (SF-36). Anxiety and depression were measured with the Hospital Anxiety and Depression Scale (HADS). Linear mixed model was used to investigate the change scores. The SF-36 scores and HADS scores of the sample were also compared with a Norwegian population norm, adjusted for age, gender, and BMI.

Results

Mental summary scores (MCS) and physical summary scores (PCS) were very low preoperatively but significantly improved (P?<?0.05) 5 years after surgery. The PCS was comparable to the population norm, while MCS was lower. Depression improved significantly from baseline to the 5-year follow-up (P?=?0.004), but anxiety did not (P?=?0.595).

Conclusions

This study demonstrates a sustained weight loss and improved, although somewhat fading, HRQL scores 5 years after BPDDS. The study also shows that BPDDS is associated with a sustained reduction in depression symptoms but not in anxiety symptoms.     

Health-related quality of life in patients on peritoneal dialysis in Serbia: comparison with hemodialysis

Abstract:  Patients' health-related quality of life (HRQoL) is an important indicator of the effectiveness of the medical care they receive. Patients who reach end-stage renal disease are older and have a considerable extent of comorbidity. The objectives of this study were (i) to evaluate HRQoL in patients at the initiation of continuous ambulatory peritoneal dialysis (CAPD) treatment (incident cohort) and in patients on long-term CAPD therapy (prevalent cohort), and (ii) to compare influence of comorbidity on HRQoL in CAPD and hemodialysis (HD) patients. In a cross-sectional study we enrolled 99 CAPD and 192 HD patients. HRQoL was assessed with the 36-item Short Form Health Survey Questionnaire (SF-36). HRQoL summary scales in both incident and prevalent groups of CAPD patients were similar for physical component summary score (PCS) and for mental component summary score (MCS). Generally, higher values were found in mental health domains in comparison to PCS. In the incident group of patients, 1 year of peritoneal dialysis treatment was associated with a slight improvement in both PCS and MCS, but statistical significance ( P  < 0.05) was found in the role-physical limitation (RP), bodily pain (BP), and vitality (VT) scales only. CAPD patients with the highest disease severity (Index of Disease Severity [IDS]-3) and physical impairment (Index of Physical Impairment [IPI]-2) scored significantly higher parameters of HRQoL than HD patients. Comorbidity had negative influence on HRQoL, but statistically significant correlation has been found in HD patients only. In conclusion, comorbid conditions had negative correlation with parameters of HRQoL in both CAPD and HD patients. One year after starting CAPD, patients reported better scores in some domains, especially in RP, BP, and VT scales. Assessment of HRQoL and comorbidity might be useful in clinical practice in the follow-up of patients treated with both CAPD and HD.     

Are Hip Resurfacing Arthroplasties Meeting the Needs of Our Patients? : A 2-Year Follow-Up Study

Hip resurfacing arthroplasty (HRA) is a treatment of end-stage hip arthritis in young patients with excellent bone stock. One hundred four consecutive HRAs (Depuy ASR, Warsaw, Ind) were performed with 36-Item Short Form Health Survey (SF-36), Western Ontario and McMaster University Osteoarthritis Index, Harris Hip Scores, and University of California, Los Angeles activity ratings obtained preoperatively, at 6 months, and at 1 and 2 years postoperatively. Four patients required conversion to total hip arthroplasty. All patients showed significant improvements in their activity, pain, stiffness, and function postoperatively. Patients with lower SF-36 mental component scores (MCSs) improved their MCS compared with those of the general population, as well as improving their pain and physical functioning scores. These findings demonstrate reliable improvements in standard quality of life measures in patients undergoing HRA, including those with low preoperative SF-36 MCS.     

Predicting quality of life six months after traumatic injury

BACKGROUND: Many factors are known to impact quality of life (QoL) after injury, but predictors of diminished QoL and the time course of recovery remain incompletely understood. This study examines predictors and correlates of QoL measured by the Short Form-36 (SF-36) one and six months postinjury. METHODS: Adults with nonneurologic blunt injury were prospectively enrolled. Demographic, injury, and socioeconomic data were collected. Patients were assessed with functional and psychologic measures. In all, 196 patients had 1-month data and 123 had 6-month data available. Scores were compared at each time point and also to population norms using t-tests. Multiple regression techniques were used to identify associations between the physical and mental component scores (PCS & MCS) of the SF-36 and patient characteristics. RESULTS: PCS scores improved significantly (32.8 +/- 0.9 versus 41.3 +/- 1.0, p < 0.05) whereas MCS scores (47.5 +/- 1.1 versus 47.2 +/- 1.1, p = NS) did not. Both remained significantly below population norms. Functional Independence Measure (FIM) at one month was predictive of PCS at 6 months. Posttraumatic stress disorder (PTSD) was predictive of lower MCS, and depression was associated with poor MCS. Injury Severity Score was not associated with PCS or MCS. CONCLUSIONS: Overall physical and mental QoL measured by the SF-36 remains significantly below population norms 6 months after traumatic injury. It is possible to identify patients at risk for diminished QoL early during recovery by screening for functional status, PTSD, social support, and depression. Interventions to address these areas should be further studied with respect to their impact on long-term QoL.     

The association between mental health,physical function,and hemodialysis mortality

BACKGROUND: Mortality rates for individuals on chronic hemodialysis remain very high; therefore, strategies are needed to identify individuals at greatest risk for mortality so preventive strategies can be implemented. One such approach is to stratify individuals by self-reported mental health and physical function. Examining these parameters at baseline, and over time, may help identify individuals at greater risk for mortality. METHODS: We enrolled 14,815 individuals with end-stage renal disease (ESRD) and followed these individuals for up to 2 years. The mean age was 61.0 +/- 15.4 years (range, 20 to 96 years) and 31% were African Americans. The SF-36 Health Survey was administered 1 to 3 months after hemodialysis initiation and 6 months later. We examined the associations between the initial SF-36 Health Survey mental component summary (MCS) and physical component summary (PCS) scores and mortality during the follow-up period, and examined the associations between 6-month decline in PCS and MCS scores and subsequent mortality. We also examined the interactions between age and MCS and PCS scores. The general population-based mean of each of these scores was 50 with a standard deviation of 10. The main outcome measurement was death. RESULTS: Self-reported baseline mental health (MCS score) and physical function (PCS score) were both independently associated with increased mortality, and 6-month decline in these parameters was also associated with increased mortality. The multivariate hazard ratios for 1-year mortality for MCS scores of less than 30, 30 to 39, and 40 to 49 were 1.48 (95% CI, 1.32 to 1.64), 1.23 (95% CI, 1.14 to 1.32) and 1.18 (95% CI, 1.10 to 1.26) compared with a MCS score of 50 or more. The hazard ratios for PCS scores of less than 20, 20 to 29, and 30 to 39 were 1.97 (95% CI, 1.64 to 2.36), 1.62 (95% CI, 1.36 to 1.92), and 1.32 (95% CI, 1.11 to 1.57) compared with a PCS score of 50 or more. Six-month decline in self-reported mental health (hazard ratio, 1.07; 95% CI, 1.02 to 1.12, per 10-point decline in MCS score) and physical function (hazard ratio, 1.25; 95% CI, 1.18 to 1.33, per 10-point decline in PCS score) were also both significantly associated with an additional increase in mortality beyond baseline risk. We also found a significant interaction between age and physical function (P = 0.02). Specifically, there was a graded response between the PCS score category and mortality in most age strata, but this relationship was not observed in the oldest age (85 years old or older). CONCLUSION: In individuals newly initiated on chronic hemodialysis, self-reported baseline mental health and physical function are important, independent predictors of mortality, and there is a graded relationship between these parameters and mortality risk. Following these parameters over time provides additional information on mortality risk. One must also consider age when interpreting the relationship between physical function and mortality.     

Prospective psychosocial monitoring of living kidney donors using the SF-36 health survey

BACKGROUND: Psychosocial assessment and monitoring of living kidney donors is not yet standard practice, despite calls for it in the literature. METHODS: Psychosocial assessment of living kidney donors was performed preoperatively and 4 months postoperatively, using the SF-36 Health Survey, the Patient Health Questionnaire psychiatric assessment, and semistructured interview. RESULTS: Assessment was acceptable to the majority of donors; 92% (44) of 48 consecutive donors completed both assessments. Preoperatively, both physical function (SF-36 Physical Component Score [PCS]) and psychosocial function (SF-36 Mental Component Score [MCS]) were significantly higher than community (state of Victoria) norms. Postoperatively, PCS and MCS fell significantly, but not below the Victorian norm. Seven donors (16%) developed adjustment disorder or anxiety disorder; their MCS were significantly lower than those without psychiatric disorder. CONCLUSIONS: It is concluded that routine psychosocial assessment performed by a psychiatrist, including the use of questionnaires, is acceptable to donors and identifies those impaired. Potential donors need to be well prepared for such assessment and well educated about the extent of physical and psychosocial impairment that might occur in the postoperative period.     

The impact of benign prostatic hyperplasia surgery on patients' quality of life.

OBJECTIVE: To assess the impact of surgical treatment of benign hyperplasia of the prostate on patients' quality of life (QoL). MATERIAL AND METHODS: The QoL of 181 patients was assessed by the health questionnaire SF-36. The measurement was carried out before and 6 months after surgery. RESULTS: After surgery, SF-36 scales improved their scores, fundamentally General Health (57.4%) and Physical Functioning (57.1%). 70.3% improved their physical component summary (PCS) and 49.1% their mental component summary (MCS). The improved PCS and MCS were not associated with the improved I-PSS or urine flow. The improved PCS was 2.2 times higher in patients who had previously scored under 44 in the PCS, 2.2 in patients who had scored over 25 in the I-PSS, and 2.9 times higher in patients without chronic diseases. With regard to MCS improvement, this was 17.1 times higher in patients who scored under 50 previously on the MCS, 3.1 in patients who scored over 4 on the IQL, 5.7 in patients without postoperative incontinence, and 3.3 times higher in patients who lived in urban areas. CONCLUSIONS: Improvement in QoL after surgery is noted more in physical than in psychological aspects. Although a reduction in the intensity of prostatic symptoms and an increase in urine flow values were noted postoperatively, the improvement QoL was not associated with improved symptoms or urinary flow.     

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.     

The association of pretreatment health-related quality of life with surgical complications for patients undergoing open surgical resection for colorectal cancer

OBJECTIVE: The purpose of this study was to define the association between pretreatment health-related quality of life (HRQL) and surgical complications for patients with colorectal cancer. SUMMARY BACKGROUND DATA: For patients with colorectal cancer, surgical complications arise from an interaction between underlying medical comorbidity, colorectal cancer severity, and quality and type of treatment provided. Measurement of HRQL provides a summarization of well-being in the context of medical comorbidity and colorectal cancer severity. The summarization of these factors may be useful in prospective risk assessment of patients about to undergo surgery for colorectal cancer. METHODS: A single-institution, prospective, cohort study of patients with colorectal adenocarcinoma was performed from August 1, 1999, to March 31, 2002. Before treatment, all participants completed Medical Outcomes Survey SF-36 (SF-36); after the first year of the study, patients also completed the colorectal cancer module of the Functional Assessment of Cancer Therapy survey (FACT-C). Information was collected on demographics, treatment, tumor variables, and complications. RESULTS: Ninety-seven patients have undergone open resection of their colorectal cancer. All patients completed SF-36; 65 completed FACT-C. Thirty patients (31%) experienced complications, including 4 (4%) deaths. Age, race, albumin level, American Society of Anesthesia class, specialty surgical training, tumor location, and stage were not associated with complications in univariate analysis. Patients experiencing surgical complications had significantly lower HRQL scores on SF-36 Social Functioning, General Health Perception, and Mental Health Index scales as well as the Mental Health Component summary score. FACT-C Social/Family, Emotional, Functional Well-Being scores, and the Colorectal Cancer Concerns score were also significantly lower for patients sustaining complications. When these HRQL scales were examined in a multivariate model including albumin level, tumor location, and ASA class, SF-36 Social Functioning (Odds Ratio [OR] = 0.98; 95% Confidence Interval [CI] = 0.97-0.99) and FACT-C Colorectal Cancer Concerns (OR = 0.89; 95% CI = 0.79-0.99) scales retained a significant association with complications. CONCLUSIONS: Pretreatment HRQL scores as measured by several scales of SF-36 and FACT-C were significantly associated with complications. Future studies should concentrate on defining the predictive role of HRQL in determining surgical outcome for patients with colorectal cancer.     

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.     

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.
