Systematic review of patient‐reported outcome measures in the surgical treatment of patients with esophageal cancer

Esophageal cancer is currently the eighth most common cancer worldwide. Improvements in operative techniques and neoadjuvant therapies have led to improved outcomes. Resection of the esophagus carries a high risk of severe complications and has a negative impact on health‐related quality of life (QOL). The aim of this study was to assess which patient‐reported outcome measures (PROMs) are used to measure QOL after esophagectomy for cancer. A comprehensive search of original articles was conducted investigating QOL after surgery for esophageal carcinoma. Two authors independently selected relevant articles, conducted clinical appraisal, and extracted data (PJ and JS). Out of 5893 articles, 58 studies were included, consisting of 41 prospective and 17 retrospective cohort studies, including a total of 6964 patients. These studies included 11 different PROMs. The existing PROMs could be divided into generic, symptom‐specific, and disease‐specific questionnaires. The European Organisation for Research and Treatment of Cancer (EORTC) QOL Questionnaire Core 30 (QLQ C‐30) along with the EORTC QLQ‐OESophagus module OES18 was the most widely used; in 42 and 32 studies, respectively. The EORTC and the Functional Assessment of Cancer Therapy (FACT) questionnaires use an oncological module and an organ‐specific module. One validation study was available, which compared the FACT and EORTC, showing moderate to poor correlation between the questionnaires. A great variety of PROMs are being used in the measurement of QOL after surgery for esophageal cancer. A questionnaire with a general module along with a disease‐specific module for assessment of QOL of different treatment modalities seem to be the most desirable, such as the EORTC and the FACT with their specific modules (EORTC QLQ‐OES18 and FACT‐E). Both are developed in different treatment modalities, such as in surgical patients. With regard to reproducibility of current results, the EORTC is recommended.     

The effect of age on short-term outcomes after abdominal surgery for pelvic organ prolapse

OBJECTIVES: To compare perioperative morbidity and 1-year outcomes of older and younger women undergoing surgery for pelvic organ prolapse (POP). DESIGN: Prospective ancillary analysis. SETTING: Academic medical centers in National Institutes of Health, National Institute of Child Health and Human Development Colpopexy and Urinary Reduction Study. PARTICIPANTS: Women with POP and no symptoms of stress incontinence. INTERVENTION: Abdominal sacrocolpopexy with randomization to receive Burch colposuspension for treatment of possible occult incontinence or not. MEASUREMENTS: Perioperative complications and Pelvic Organ Prolapse Quantification and quality-of-life (QOL) questionnaires (Pelvic Floor Distress Inventory, Pelvic Floor Impact Questionnaire, and Medical Outcomes Study Short-Form Health Survey (SF-36) preoperatively, immediately postoperatively, and 6 weeks and 3 and 12 months postoperatively). RESULTS: Three hundred twenty-two women aged 31 to 82 (21% aged > or =70), 93% white. Older women had higher baseline comorbidity (P<.001) and more severe POP (P=.003). Controlling for prolapse stage and whether Burch was performed, there were no age differences in complication rates. Older women had longer hospital stays (3.1+/-1.0 vs 2.7+/-1.5 days, P=.02) and higher prevalence of incontinence at 6 weeks (54.7% vs 37.2%, P=.005). At 3 and 12 months, there were no differences in self-reported incontinence, stress testing for incontinence, or prolapse stage. Improvements from baseline were significant on all QOL measures but with no age differences. CONCLUSION: Outcomes of prolapse surgery were comparable between older and younger women except that older women had slightly longer hospital stays.     

Quality of life in gastric cancer

AIM: To summarize the empirical research on assessing quality of life (QOL) in patients with gastric carcinoma. METHODS: Literature searches were conducted in MedLine from 1966 to February 2004. RESULTS: Twenty-six studies were identified. QOL was used as an outcome measure in virtually all identified studies, such as those examining the effects of gastric cancer and various medical or surgical treatments in the patients. QOL was assessed mainly with generic measures; the social dimensions of QOL were largely neglected.The lack of gastric cancer-specific QOL measures hampers QOL research up to now.The gastric cancer-specific EORTC-QLQ-STO22 and the FACT-Ga are important additions to the arsenal of disease-specific QOL measures. In most of the studies, the label QOL is used for questionnaires, which only assess symptoms or performance status, or are physician-reported rather than patient-reported outcomes. CONCLUSION: QOL in patients with gastric cancer deserves more systematic studies, especially as one of the outcome measures in randomized clinical trials. Results of studies that include QOL in patients with gastric cancer should be applied in clinical care, which aims at improving QOL of these patients.     

Multivariate analysis of factors influencing quality of life and utility in patients with haemophilia.

BACKGROUND AND OBJECTIVES: Although several studies have determined quality of life (QOL) in patients with hemophilia, generic questionnaires have rarely been used. The objectives of our study were; 1) to measure QOL and utility in patients with hemophilia using the Short Form 36 (SF-36) and the EuroQOL questionnaires; 2) to evaluate the influence of some clinical variables on QOL and utility; 3) to assess the correlation between the two questionnaires. DESIGN AND METHODS: All consecutive patients with hemophilia were asked to complete the SF-36 and the EuroQOL questionnaires. The following information was recorded from each patient: age, type of hemophilia, severity of disease, HCV and HIV infection, number of bleeding episodes and cumulative dose of coagulation factors over the previous year. These items were entered into a multivariate analysis to assess their effect on QOL. Correlation analyses were conducted to evaluate the relationship between the EuroQOL and SF-36. RESULTS: Fifty-six patients completed the SF-36 and the EuroQOL questionnaires. The mean scores of the SF-36 ranged from 55.2 (general health) to 74.7 (social functioning). The EuroQOLself-classifier and the EuroQOLvas showed a mean score of 0.67 (SD=0.26) and 0.66 (SD=0.17), respectively. Among the clinical variables, age significantly influenced both the EuroQOL and the SF-36 scores. The EuroQOL indices showed a statistically significant correlation with each dimension of the SF-36. INTERPRETATION AND CONCLUSIONS: Our study quantified the degree to which QOL is impaired in patients with hemophilia by using both a generic questionnaire and a utility-based approach.

Quality of life assessment: a comparison of four questionnaires: for measuring improvements after total hip replacement

Summary Three experimental questionnaires were compared with the Influence of Rheumatic Diseases on Health and Lifestyle (IRGL) questionnaire, a Dutch version of the Arthritis Impact Measurement Scales. Sixty-two patients with osteoarthritis (OA) and 35 patients with rheumatoid arthritis (RA), all of whom underwent hip arthroplasty, completed the study.Results showed that visual analogue scales for pain, stiffness, fatigue, and anxiety were strongly correlated with a number of the IRGL scales.Patient preference scales were sensitive to change and provided additional information on aspects of the patients' quality of life (QOL) that were felt to be important by the patients themselves. The questionnaire on performance in various roles in life was insensitive to change.In existing questionnaires, there is an attempt to represent the concept of QOL in terms of its most important aspects. Such realizations of the concept of QOL are not entirely suitable for application in clinical trials. The IRGL is overly complex, and its sometimes comprehensive scales do not deal with the possible effects of treatment. Neither of these properties is conducive to sensitivity to change. Visual analogue scales reduce the complexity. A simpler representation of QOL that can evaluate aspects relevant to treatment is recommended.     

Usefulness of a linear analog scale questionnaire to measure health-related quality of life in elderly patients with chronic obstructive pulmonary disease

OBJECTIVES: To examine the validity, discriminatory ability, and responsiveness of health-related quality-of-life (HRQoL) questionnaires using a linear analog scale (Quality of Life (QOL) scale) for chronic obstructive pulmonary disease (COPD). DESIGN: Cross-sectional and longitudinal. SETTING: Outpatient. PARTICIPANTS: One hundred two elderly subjects with mild to severe COPD. MEASUREMENTS: Scores on the QOL scale, the St. George's Respiratory Questionnaire (SGRQ), and the 36-item Short-Form Health Survey questionnaire (SF-36) and various clinical parameters were recorded. The correlations between these QOL questionnaires and various clinical parameters were then examined. The responses of 31 elderly COPD patients to the QOL scale and the SGRQ before and 3 months after the completion of a comprehensive pulmonary rehabilitation program were compared longitudinally. RESULTS: On cross-sectional study, the QOL scale showed a significant correlation with the total score and three components of the SGRQ. The QOL scale correlated significantly with all components of the SF-36, but the total SGRQ score correlated with only six components of the SF-36, excluding vitality and the mental health index. Both the QOL scale and the total score of the SGRQ correlated significantly with the oxygen cost diagram (OCD), Morale scale, 6-minute walking distance (6MWD), forced expiratory volume in 1 second, and instrumental activities of daily living (IADL) score. When subjects were divided into three groups according to disease severity (mild, moderate, severe) using American Thoracic Society guidelines, the total SGRQ score discriminated between the three groups. The QOL scale could not discriminate between mild and moderate or moderate and severe. On longitudinal study, 3 months after finishing the comprehensive pulmonary rehabilitation program, the QOL scale, the SGRQ, 6MWD, and OCD all showed significant improvement. The difference in the QOL scale after the comprehensive pulmonary rehabilitation program showed a significant correlation with changes in the SGRQ total score and the OCD but not with the 6MWD. CONCLUSION: The QOL scale is similar to more-complex questionnaires such as the SGRQ in terms of validity and responsiveness for evaluating disease-specific HRQoL in elderly COPD patients. In clinical settings, the QOL scale, as a simple questionnaire, may be useful for disease-specific HRQoL assessments in elderly COPD patients.     

Assessment of quality of life in adults receiving long-term growth hormone replacement compared to control subjects

OBJECTIVE: There are few studies of quality of life (QOL) in adults with growth hormone deficiency (GHD) compared to matched control populations without GHD. These have shown impairments in a variety of QOL measures, which improve but do not normalize after short-term replacement with GH. There is little information on QOL in long-term treated GHD patients compared with controls without GHD. PATIENTS AND METHODS: A total of 120 adults with GHD who had received GH replacement for at least 1 year were identified from the neuroendocrine clinic. Patients were asked to complete eight QOL questionnaires and an Energy Visual Analogue Scale (VAS). Results were compared with 83 control subjects without GHD from the local population who agreed to complete seven of the QOL questionnaires (excluding Disease Impact scale) and the energy VAS. The eight questionnaires were a combination of generic and disease-specific questionnaires used to assess health related QOL, namely: Short Form-36 (SF-36), Nottingham Health Profile (NHP), Disease Impact, Life Fulfilment and Satisfaction scales, Mental Fatigue Questionnaire (MFQ) and Self Esteem scale, Hospital Anxiety Depression (HAD) scale and QOL-AGHDA (assessment of GHD in adults). RESULTS: Eighty-nine patients returned questionnaires and 85 (71%) had complete data for analysis. The mean (SD) duration of GH replacement was 36.0 +/- 26.4 (range 13-159) months. Mean age was 43.9 +/- 15.8 years (37 males) in treated GHD patients compared to a mean age 41.7 +/- 10.5 years (32 males) in the controls. Mean IGF-1 levels were 22.5 +/- 13.6 nmol/l in the GHD patients and the mean dose of GH replacement was 1.2 +/- 0.4 IU daily. Analysis of the QOL questionnaires from the GH treated patients revealed highly significant impairments in all measures (most P 相似文献   

Development of a parent-proxy quality-of-life chronic cough-specific questionnaire: clinical impact vs psychometric evaluations

BACKGROUND: Chronic cough affects at least 7% of children, and the impact of this on families is significant. Although adult cough-specific quality-of-life (QOL) instruments have been shown to be a useful cough outcome measure, no suitable cough-specific QOL for parents of children with chronic cough exists. This article compares two methods of item reduction (clinical impact and psychometric) and reports on the statistical properties of both QOL instruments. METHOD: One hundred seventy children (97 boys and 73 girls; median age, 4 years; interquartile range, 3 to 7.25 years) and one of their parents participated. A preliminary 50-item parent cough-specific QOL (PC-QOL) questionnaire was developed from conversations with parents of children with chronic cough (ie, cough for > 3 weeks). Parents also completed generic QOL questionnaires (eg, Pediatric Quality of Life Inventory, version 4.0 [PedsQL4.0] and the 12-item Short Form Health Survey, version 2 [SF-12v2]). RESULTS: The clinical impact and psychometric method of item reduction resulted in 27-item and 26-item PC-QOL questionnaires, respectively, with approximately 50% of items overlapping. Internal consistency among the final items from both methods was excellent. Some evidence for concurrent and criterion validity of both methods was established as significant correlations were found between subscales of the PC-QOL questionnaire and the scales of the SF-12v2 and PedsQL4.0 scores. The PC-QOL questionnaire derived from both methods was sensitive to change following an intervention. CONCLUSION: Chronic cough significantly impacts on the QOL of both parents and children. Although the PC-QOL questionnaires derived from a clinical impact method and from a psychometric method contained different items, both versions were shown to be internally consistent and valid. Further testing is required to compare both final versions to objective and subjective cough measures.

Quality of life,social support,and knowledge of disease in women with rheumatoid arthritis

OBJECTIVE: To examine the relationships between the quality of life (QOL) of women with rheumatoid arthritis (RA) and 1). their perceived levels of social support and 2). their primary caregivers' knowledge of RA and its treatment. METHODS: Women aged 40-60 years with established RA completed validated questionnaires on health status (Arthritis Impact Measurement Scales 2) and satisfaction with the levels of social support from their primary caregiver (Significant Others Scale A). In addition, both the caregivers and patients independently completed questionnaires that were designed to elicit knowledge of RA and its treatment. RESULTS: Fifty-eight patients and their primary caregivers completed the questionnaires. Analysis of the patients' health status demonstrated widespread biopsychosocial impairments. Arthritis pain, identified as the poorest health status dimension, was associated with the lowest levels of satisfaction, and received the highest priority for health status improvement. In contrast, the patients reported highest levels of satisfaction with social support from family and friends. Positive associations between social support variables and a number of QOL measures were observed. Both the caregivers and the patients displayed limited knowledge of RA and its treatment. Associations between the levels of knowledge and the patients' QOL measures were not observed. CONCLUSION: In this study of women with RA and their caregivers, a limited knowledge of disease did not appear to impact QOL measures. However, failure to detect an association between knowledge of disease and QOL may have been influenced by a combination of the relatively small study numbers and insufficient variation in caregivers' knowledge, such that a floor effect existed.     

The impact of facial lipoatrophy treatment with polymethyl methacrylate in AIDS patients as measured by four quality-of-life questionnaires

Life-expectancy increased in patients infected with HIV/AIDS with the advent of highly active antiretroviral therapy (ART). Facial lipoatrophy is a common complication in these patients, eventually leading to stigma, segregation and a negative impact in quality of life (QOL). We measured the impact of the treatment of facial lipoatrophy with polymethyl methacrylate (PMMA) in the QOL of patients with HIV/AIDS by using four questionnaires that address QOL. Forty consecutive patients on ART referred for facial lipoatrophy treatment were enrolled in this study. The first 20 were allocated to the intervention group and were treated with tissue augmentation with PMMA. The other 20 were allocated to the control group, which received treatment only after six months. At baseline, four questionnaires were applied to all patients in both groups and again after six months. The variation in scores within the control group for all domains of all four instruments was significantly better when compared with that within the control group. We detected improvement in the QOL of patients with HIV/AIDS and facial lipoatrophy when they were treated with PMMA.     

The influence of age, gender, and race on the prevalence of depression in heart failure patients

OBJECTIVES: The goal of this study was to determine the prevalence of depression in an out-patient heart failure (HF) population; its relationship to quality of life (QOL); and the impact of gender, race, and age. BACKGROUND: Most studies of depression in HF have evaluated hospitalized patients (a small percentage of the population) and have ignored the influence of various patient characteristics. Although reported depression rates among hospitalized patients range from 13% to 77.5%, out-patient studies have been small, have reported rates of 13% to 42%, and have not adequately accounted for the impact of age, race, or gender. METHODS: A total of 155 patients with stable New York Heart Association functional class II, III, and IV HF and an ejection fraction <40% were given questionnaires to assess QOL and depression. These included the Medical Outcomes Study Short Form, the Minnesota Living with Heart Failure questionnaire, and the Beck Depression Inventory (BDI). Depression was defined as a score on the BDI of > or =10. RESULTS: A total of 48% of the patients scored as depressed. Depressed patients tended to be younger than non-depressed patients. Women were more likely (64%) to be depressed than men (44%). Among men, blacks (34%) tended to have less depression than whites (54%). Depressed patients scored significantly worse than non-depressed patients on all components of both the questionnaires measuring QOL. However, they did not differ in ejection fraction or treatment, except that depressed patients were significantly less likely to be receiving beta-blockers. CONCLUSIONS: Depression is common in patients with HF, with age, gender, and race influencing its prevalence in ways similar to those observed in the general population. These data suggest that pharmacologic or non-pharmacologic treatment of depression might improve the QOL of HF patients.     

Quality of life and prognosis in heart failure: results of the Beta-Blocker Evaluation of Survival Trial (BEST)

BackgroundQuality of life (QOL) was a prespecified secondary end point in the Beta-Blocker Evaluation of Survival Trial. The Beta-Blocker Evaluation of Survival Trial used four QOL questionnaires to evaluate patient health status over time in response to treatment with placebo or bucindolol. The goal of the current study was to determine the relationship between the different questionnaires, assess the effect of treatment on health status, and evaluate the association between changes in health status and prognosis.MethodsThe San Diego Heart Failure (SDHF), Minnesota Living with Heart Failure (MLHF), Patient Global Assessment (PGA), and Physician Global Assessment (PhyGA) questionnaires were measured at baseline through 48 months of follow-up. For SDHF and MLHF, changes from baseline were calculated. Spearman correlation was used to assess relationships, and Cox Proportional Hazards regression was used to predict time to all-cause mortality, and mortality or heart failure hospitalization, bivariately and multivariately. To determine whether beta-blocker treatment affected QOL, the Wilcoxon rank-sum test was used to compare treatment groups.ResultsAt 12 months, SDHF (r = +0.56, P = .0001), PGA (r = +0.36, P = .0001), and PhyGA (r = +0.37, P = .0001) correlated with MLHF. SDHF (P = .0001), MLHF (P = .0004), PGA (P = .0001), and PhyGA (P = .0001) were all strongly associated with all-cause mortality, with low values of each associated with a lower hazard. For the combined end point of all-cause mortality or heart failure hospitalization, change in QOL with each instrument had a P value of .0001. At 12 months, bucindolol-treated patients had improvement in both PhyGA and PGA compared with placebo; neither the SDHF nor the MLWF instrument distinguished between the two treatment groups unless a worst-rank assignment was used for patients who died.ConclusionThe four instruments correlate with each other and predict clinical end points, suggesting that each is a valid measure of health status. According to the PGA and the PhyGA, bucindolol improves QOL.     

Mesures de qualité de vie au cours du lupus systémique : état des lieux,actualité et utilisation pratique

Systemic lupus erythematosus (SLE) is a chronic disease that considerably hampers patient's daily living. Qualitative studies with patients’ interviews have been conducted to describe the experiences and perspectives of adults living with SLE. Among existing generic and disease-specific quality of life (QOL) questionnaires, none succeeded to exhaustively measure patient's preoccupations. However, these tools are useful to quantify the burden of the disease. Social precariousness, socioeconomic status and education level are intimately correlated to QOL measures, either generic or disease-specific. Musculoskeletal disease activity is also associated with a lower QOL. Using disease-specific tools may be useful because of a better aptitude to record an improvement in health status. Moreover, using generic and disease-specific questionnaires together may help to identify factors associated with a lower quality of life but not related to SLE from the patient's perspective (such as smoking or obesity). Developing new ways of recording QOL data in the future may help to evaluate the real benefit of using QOL scales in daily practice.     

The effect of complete decongestive therapy on the quality of life of patients with peripheral lymphedema

Lymphedema is a chronic disorder which can adversely affect quality of life (QOL). The purpose of this study was 1) to evaluate whether QOL was improved in patients with lymphedema following Complete Decongestive Therapy (CDT), and 2) whether limb volume change as a result of treatment correlated with change in QOL. Thirty-six patients with peripheral lymphedema from varying causes were enrolled in the study. The QOL of each participant, with regard to physical, functional, and psychosocial concerns, was measured by pre- and post-treatment questionnaires. Percent edema volume reduction was calculated for each patient with only one affected limb. QOL pre- and post-treatment scores were assessed by multivariate repeated measures analysis. QOL scores differed significantly (p<0.05) between pre- and posttreatment in all areas of inquiry. Patients with lower extremity lymphedema had significantly greater mean improvement in QOL scores compared with patients with upper extremity lymphedema (p=0.02). There was no correlation between percent edema volume reduction and post-treatment QOL improvement. This study suggests that significant improvements are made in the QOL of patients exhibiting peripheral lymphedema following CDT, which is not necessarily correlated with limb volume reduction.     

Nonfunctioning pituitary adenoma: incidence,causes of death and quality of life in relation to pituitary function

The incidence of clinically significant, nonfunctioning pituitary adenoma, requiring surgical treatment, has not been established. According to previous studies, both surgery type and subsequent radiotherapy may have an impact on quality of life (QOL), and some studies have shown increased cardiovascular mortality in patients with pituitary disease. We studied all patients with functionless, suprasellar pituitary adenoma who were operated on during the period 1985–1996 (N = 192; transsphenoidal surgery = 160, craniotomy = 32). QOL was evaluated from Short Form 36 and Major Depression Inventory questionnaires. Causes of death were obtained from the Danish Register of Causes of Death. Incidence was 5.6/mill/year. Postoperatively, 27% of the patients had normal pituitary function and 27% were panhypopituitary. Fifty three patients had died. Death from cardiovascular, cerebrovascular and malignant diseases was not increased. Overall, QOL was not different from QOL of an age- and sex matched background population. QOL was, however, impaired in patients who had undergone craniotomy as compared to patients undergoing transsphenoidal surgery. QOL was not reduced in hypopituitary patients or in patients receiving radiotherapy. The study was supported by grants from The Aarhus University Hospital Research Initiative and The Obel Family Foundation, Aalborg, Denmark     

Liver transplantation and quality of life.

To date, more than 50,000 liver transplantations have been performed around the world; the survival rate five years after transplantation ranges from 60% to 65%. One of the fundamental objectives for liver transplantation teams is to achieve the best possible quality of life (QOL) for the patients. A concise analysis of the methodology used (15 questionnaires) to measure QOL of patients with liver transplants is described. The authors suggest that now is the time to establish a database so that a validated instrument will be available to compare QOL results from all the liver transplantation programs. Liver transplantation is believed to improve QOL, although there are several problems with some of the papers published on this subject. Some studies are retrospective, whereas in others, patients in bad physical conditions are excluded from the study; in quite a few prospective studies, deaths are not included in the data analysis. Finally, the authors provide a brief, concise analysis of late complications and of recurrence of the disease after liver transplantation, which influence QOL.     

Assessment of quality of life in Iranian asthmatic children, young adults and their caregivers

Interest in the impact of illness on day to day function is leading investigators to include both disease specific and generic health related quality of life (HR QOL) questionnaires in a broad range of clinical studies and to gain a full picture of the impact of asthma on the lives of children with this condition, it is necessary to make direct measurement of health related quality of life. In response to this need, we used the Juniper's pediatric asthma quality of life questionnaire (PAQLQ) and Juniper's Pediatric Asthma Caregiver's Quality of Life Questionnaire (PACQLQ) that has been developed based on guidelines for construction of over a dozen validated disease specific quality of life instruments. The PAQLQ consists of 23 items that in children with asthma have been identified as troublesome in their daily lives and PACQLQ that contains 13 items in two domains of emotional and activities disturbances. The study design consisted of an 18 month single cohort study. Patients participating in the study were 113 children, 7-17 years of age, with a wide range of asthma severity and their caregivers. For each patient a PAQLQ and for each caregiver a PACQLQ was completed. One week before visit patients recorded morning peak flow rates, medication use and symptoms in a diary. After complete physical examination, for determining of asthma severity, spirometry was performed. The questionnaires after statically analysis showed good levels of both longitudinal and cross sectional correlations with the conventional asthma indices and with general quality of life. We found that consistently QOL in boys were more disturbed than females, a good relevancy between severity of asthma and QOL scores and more disturbances of QOL in caregivers of male asthmatic patients than caregivers of female asthmatic patients. We could not find any significant relevancy between FEV1 percentage of predicted and overall scores of QOL. Smaller airways, and higher airway resistance and more activity of males than females may explain why boys have more disturbed life style than females.     

Quality of life in elderly heart failure patients

Quality of life(QOL),as a relevant area of research in the understanding of heart failure(HF)patient outcomes,has been increasingly studied during the last two decades.The purposes of this review article are to (1)describe QOL in older adults with HF,(2) identify and critique research designed to test interventions to improve QOL,(3)identify gaps in the literature,and (4)provide recommendations for future research.Seventeen studies describing QOL in older adults with HF were identified.Elderly HF patient QOL has been reported to be fair to poor and is worse as compared to a healthy control group.Furthermore,there is some evidence that suggests that QOL is better in older adults than younger adults and worse in women(both older and younger)than in men,although these findings are not consistent across studies.Predictors of QOL and its dimensions in older HF patients included demographic,clinical,and psychosocial variables.Sixteen interventional studies were identified that reported QOL as an outcome in older adults.Findings among randomized clinical trials(RCTs)to improve QOL outcomes in elderly HF patients do not allow strong conclusions about the benefits of the interventions.It must be noted,though,that while not all studies reported improvements in QOL(either significant or as a trend), no studies reported deterioration in QOL with randomization to an intervention versus control.These studies were limited by several methodological issues.While there has been some research of QOL in this elderly cohort,it is paramount that we address methodological issues and thereby improve the scientific rigor of our research,continue to explore QOL in elderly HF patients,and design intervention trials for elders at risk for poor QOL.
