A comparison of four quality of life instruments in cardiac patients: SF-36, QLI, QLMI, and SEIQoL

Benefits of pulmonary rehabilitation in COPD patients with mild cognitive impairment - A pilot study

BACKGROUND

Cognitive impairment might interfere with the efficacy of Pulmonary Rehabilitation (PR) in Chronic Obstructive Pulmonary Disease (COPD). We aimed to identify differential responses to PR between cognitively impaired (CI) and cognitively normal (CN) COPD patients by assessing health status and exercise capacity.

METHODS

Sixty patients (FEV₁: 47 ± 15%) were classified as CI or CN according to the Montreal Cognitive Assessment (MoCA ≤25points) and completed a 3-week inpatient PR program. Cognitive function (neuropsychological battery), health-status (36-Item Short Form Survey [SF-36]), and exercise capacity (6-min walk test [6MWT], cycle-endurance test [CET]) were assessed before and after PR. Responsiveness to PR was estimated by mean change (delta-value [Δ]) and the d-Effect Size (ES).

RESULTS

Twenty-five COPD patients (42%) presented evidence of mild CI prior to PR. Both, CI and CN patients significantly improved global cognitive function, health status (the majority of SF-36 components), and exercise capacity (6MWT and cycle endurance) in response to PR. Compared to CN, CI patients did not improve SF-36 subdomains of "role emotional" and "bodily pain", and demonstrated a lower magnitude of improvement in 6MWT ([Δ]: 25 m; ES: 0.21) compared to CN ([Δ]: 46 m; ES: 0.54).

CONCLUSIONS

PR has favorable effects on global cognitive function, health status, and exercise capacity in both CI and CN COPD patients. There was no concrete evidence to indicate interference of cognitive impairment to PR effectiveness.

Home-Based Arm Cardiac Rehabilitation in Disabled Veterans: A Pilot Study

One of the cornerstones of treatment after acute coronary syndromes is cardiac rehabilitation (CR). However, traditional CR remains underused in the United States due to comorbidities and geographical limitations. To evaluate feasibility and safety of our individually tailored CR program, we evaluated twelve weeks of tele-monitored home-based arm ergometer and weight training exercises in seven Veterans. Prior to beginning our CR program, all Veterans underwent an arm ergometer stress test and training in the proper techniques for arm exercises and weight training. Seattle Angina Questionnaire (SAQ) and the MacNew Heart Disease Health-related Quality of Life (MacNew) questionnaire were administered at the beginning and conclusion of the program. Six patients completed the study. One withdrew due to generalized weakness. There were no adverse events during the study period. There was a perceived improvement in heart disease related global (4.47 to 4.61), physical, emotional, and social well-being by the MacNew questionnaire. The SAQ showed improvement in physical limitation, angina frequency, treatment satisfaction, and overall quality of life (36.1 to 51.7) after completion of our tailored CR program. There was a decrease in average blood pressure and patients were able to exercise seven minutes longer and workload increased eight additional watts. This pilot study demonstrates the safety and feasibility of a home-based arm cardiac rehabilitation program. These tailored programs may improve quality of life in coronary artery disease patients with disabilities.

Agreement between the Schedule for the Evaluation of Individual Quality of Life-Direct Weighting (SEIQoL-DW) interview and a paper-administered adaption

BACKGROUND

The Schedule for the Evaluation of Individual Quality of Life-Direct Weighting (SEIQoL-DW) is a prevalent face-to-face interview method for measuring quality of life by integrating respondent-generated dimensions. To apply this method in clinical trials, a paper-administered alternative would be of interest. Therefore, our study aimed to analyze the agreement between the SEIQoL-DW and a paper questionnaire version (SEIQoL-PF/G).

METHODS

In a crossover design, both measures were completed in a random sequence. 104 patients at a heart surgery hospital in Germany were randomly assigned to receive either the SEIQoL-DW or the SEIQoL-PF/G as the first measurement in the sequence. Patients were approached on their earliest stable day after surgery. The average time between both measurements was 1 day (mean 1.3; SD 0.8). Agreement regarding the indices, ratings, and weightings of nominated life areas (cues) was explored using Bland-Altman plots with 95% limits of agreement (LoA). Agreement of the SEIQoL indices was defined as acceptable if the LoA did not exceed a threshold of 10 scale points. Data from n = 99 patients were included in the agreement analysis.

RESULTS

Both measures led to similarly nominated cues. The most frequently nominated cues were "physical health" and "family". In the Bland-Altman plot, the indices showed a mean of differences of 2 points (95% CI, - 1 to 6). The upper LoA showed a difference of 36 points (95% CI, 30 to 42), and the lower LoA showed a difference of - 31 points (95% CI, - 37 to - 26). Thus, the LoAs and confidence intervals exceeded the predefined threshold. The Bland-Altman plots for the cue levels and cue weights showed similar results. The SEIQoL-PF/G version showed a tendency for equal weighting of cues, while the weighting procedure of the SEIQoL-DW led to greater variability.

CONCLUSIONS

For cardiac surgery patients, use of the current version of the SEIQoL-PF/G as a substitute for the SEIQoL-DW is not recommended. The current questionnaire weighting method seems to be unable to distinguish weighting for different cues. Therefore, the further design of a weighting method without interviewer support as a paper-administered measure of individual quality of life is desirable.

Long-Term Quality of Life Outcomes in Adult Survivors After Anomalous Pulmonary Venous Drainage Repair

BACKGROUND

We sought to determine the long-term quality of life after repair of anomalous pulmonary venous drainage using the Short Form (SF)-36 questionnaire in adult survivors.

METHODS

All patients who underwent repair of partial or total anomalous pulmonary venous drainage (PAPVD or TAPVD) and were 18 years of age or older with a current contact number were identified from the hospital database. The mean age of the 101 patients was 26 ± 7 years (range, 18-49) old. Patients completed the SF-36 quality of life questionnaire via telephone. The results of the 8 domains of the SF-36 questionnaire and the derived health state summary score (SF-6-Dimension) were compared against an age-matched Australian population data.

RESULTS

Compared with Australian population age-matched data, the 18- to 24-year-old TAPVD/PAPVD patients ranked their health higher in 1 of 8 domains; however the SF-6-Dimension scores were similar (0.75 for TAPVD and PAPVD patients vs 0.77 for the Australian population, P = .2). In the 25-50 age group TAPVD/PAPVD patients ranked their health higher in 3 of 8 domains. However the SF-6-Dimension scores were similar to Australian age-matched population (0.78 for TAPVD and PAPVD patients vs 0.77 for the Australian population, P = .51).

CONCLUSIONS

Young adult survivors after anomalous pulmonary venous drainage repair have similar quality of life outcomes as age-matched Australian control subjects as measured by SF-6-Dimension.

Correlation Between Exercise Capacity and Quality of Life in Patients With Cardiac Disease

PURPOSE

Patients are referred to exercise-based cardiac rehabilitation (ECR) to increase exercise capacity and health-related quality of life (HRQOL) and thereby reduce risk of morbidity and mortality. The purpose of this study was to examine the correlation between exercise capacity and HRQOL. Furthermore, this study examined whether improvements in HRQOL were directly related to improvements in exercise capacity.

METHODS

The study included 277 patients participating in ECR. HRQOL was assessed using the Medical Outcomes Study 36-item Short Form Health Survey (SF-36), and exercise capacity was measured as peak oxygen uptake ((Equation is included in full-text article.)O2peak) and oxygen uptake ((Equation is included in full-text article.)O2) at the ventilatory threshold (VTh). Patients were examined before and after completion of an 8-wk ECR program.

RESULTS

Analyses at baseline showed a significant correlation between (Equation is included in full-text article.)O2peak and VTh and physical functioning (PF), role limitations because of physical problems (RP), general health perceptions (GH), vitality (VT), and physical component summary (PCS) on the SF-36; PF was the only dimension showing a moderate correlation (>0.40 Spearman ρ) with (Equation is included in full-text article.)O2peak. The follow-up analyses demonstrated a significant correlation between changes in (Equation is included in full-text article.)O2peak and changes in PF, RP, VT, and MH. Changes in (Equation is included in full-text article.)O2 peak explained 4% of the changes in the PF and VT scores.

CONCLUSION

The correlations between exercise capacity and HRQOL were weak and varied considerably among patients. The ECR program improved both exercise capacity and HRQOL, but it was not necessarily the same patients who improved both parameters. Therefore, it is recommended to use separate objective measures and patient-reported outcomes when evaluating the effect of ECR.

Improvements in functional and cognitive status following short-term pulmonary rehabilitation in COPD lung transplant recipients: a pilot study

BACKGROUND

Pulmonary rehabilitation (PR) following lung transplantation (LTx) is considered part of the optimal treatment in chronic obstructive pulmonary disease (COPD) for favourable post-operative outcomes. We investigated the effects of a PR intervention in the post-transplant phase with regard to lung function, exercise responses and cognitive function in COPD LTx recipients.

METHODS

24 COPD LTx recipients (mean±sd forced expiratory volume in 1 s 75±22% predicted) were assigned to a comprehensive 3-week inpatient PR programme. Changes from PR admission to discharge in lung function variables, 6-min walk test-derived outcomes and cognitive function were assessed and examined for several factors. The magnitude of changes was interpreted by effect size (ES).

RESULTS

In response to the PR intervention, LTx recipients had improved lung function with regard to diffusing capacity of the lung for carbon monoxide (+4.3%; p=0.012) and static hyperinflation (residual volume/total lung capacity -2.3%; p=0.017), increased exercise capacity (6-min walk test +86 m; p<0.001), and had small to large improvements (ES range 0.23-1.00; all p≤0.34) in 50% of the administered cognitive tests. Learning skills and memory ability presented the greatest benefits (ES composite scores 0.62 and 0.31, respectively), which remained similar after stratification by single or bilateral LTx and sex.

CONCLUSIONS

PR is an effective treatment for LTx recipients in the post-transplant phase, improving lung function, exercise responses, and domains of cognitive function of learning, memory and psychomotor speed. PR may facilitate the course of post-operative treatment and should be recommended in LTx.

Treatment selection of early stage non-small cell lung cancer: the role of the patient in clinical decision making

BACKGROUND

The objective of this study is to investigate the role and experience of early stage non-small cell lung cancer (NSCLC) patient in decision making process concerning treatment selection in the current clinical practice.

METHODS

Stage I-II NSCLC patients (surgery 55 patients, SBRT 29 patients, median age 68) were included in this prospective study and completed a questionnaire that explored: (1) perceived patient knowledge of the advantages and disadvantages of the treatment options, (2) experience with current clinical decision making, and (3) the information that the patient reported to have received from their treating physician. This was assessed by multiple-choice, 1-5 Likert Scale, and open questions. The Decisional Conflict Scale was used to assess the decisional conflict. Health related quality of life (HRQoL) was measured with SF-36 questionnaire.

RESULTS

In 19% of patients, there was self-reported perceived lack of knowledge about the advantages and disadvantages of the treatment options. Seventy-four percent of patients felt that they were sufficiently involved in decision-making by their physician, and 81% found it important to be involved in decision making. Forty percent experienced decisional conflict, and one-in-five patients to such an extent that it made them feel unsure about the decision. Subscores with regard to feeling uninformed and on uncertainty, contributed the most to decisional conflict, as 36% felt uninformed and 17% of patients were not satisfied with their decision. HRQoL was not influenced by patient experience with decision-making or patient preferences for shared decision making.

CONCLUSIONS

Dutch early-stage NSCLC patients find it important to be involved in treatment decision making. Yet a substantial proportion experiences decisional conflict and feels uninformed. Better patient information and/or involvement in treatment-decision-making is needed in order to improve patient knowledge and hopefully reduce decisional conflict.

Clinical outcomes and quality of life after surgery for dilated ascending aorta at the time of aortic valve replacement; wrapping versus graft replacement

Wrapping and graft replacement are two optional procedures for the treatment of dilated ascending aorta at the time of aortic valve replacement (AVR). Wrapping is considered less invasive. The aim of this study was to compare the short- and long-term clinical outcomes as well as the long-term quality of life in patients undergoing these two procedures.This study enrolled 40 consecutive patients with dilated ascending aorta who had undergone either wrapping (WAA group, n=20) or replacement (RAA group, n=20) of the ascending aorta at the time of AVR. Short-term outcomes, long-term deaths, and aortic events were evaluated, as was quality of life using the SF-36 Short Form. Long-term maximal proximal aortic diameter was also obtained.There were no early deaths in either group. Pump time was shorter, and transfusion (55% vs. 95%, p=0.035) and postoperative atrial fibrillation (5% vs. 30%, p=0.036) rates were lower, in the WAA than in the RAA group. At a mean follow-up of 4.9 years, the overall 5 year survival rates in the WAA and RAA groups were 78.1% and 87.5%, respectively. There were no significant between group differences in SF-36 scores in any subcategory of this survey. Long-term maximal aortic diameter remained stable in both groups. Both surgical interventions for dilated ascending aorta at the time of AVR yield favorable and comparable results in patients with suitable anatomy. Furthermore, we found no differences in quality of life between these procedures.

Domains of quality of life freely expressed by cancer patients and their caregivers: contribution of the SEIQoL

Background

The purposes of this study, performed on a large sample of cancer patient-caregiver dyads, were: i) to simultaneously investigate, using an individualized quality of life (QoL) measure (Schedule for the Evaluation of Individual QoL, SEIQoL), the QoL domains freely expressed by cancer patients and their caregivers, and ii) to explore overlapping between the SEIQoL assessment and QoL assessment using traditional instruments.

Methods

The study employed a cross-sectional design including cancer patients who were going to receive chemotherapy treatment and their caregivers. Quality of life was assessed using condition-specific questionnaires (EORTC QLQ-C30 and CarGOQoL), generic health-related questionnaire (SF-36), and open individualized measure (SEIQoL).

Results

The final sample included 205 patient-caregiver dyads. From the SEIQoL, Family, Health, and Leisures were the most freely expressed QoL domains by patients and caregivers, but reported with different weights. Love life and financial issues were less spontaneously mentioned. The SEIQoL index was moderately correlated to the condition-specific QoL questionnaires (R lower than |0.40|) and to SF-36 (correlation coefficients: R ranging from 0.17 to 0.31).

Conclusion

Individualized QoL measures allow individuals to spontaneously express important, non-predefined domains. This study highlights the need to explore QoL using a combination of individualized questionnaires and standardized questionnaires, capturing complementary facets that patients consider important in their life.

Health status of COPD patients undergoing pulmonary rehabilitation: A comparative responsiveness of the CAT and SGRQ

The St. George’s Respiratory Questionnaire (SGRQ) and chronic obstructive pulmonary disease (COPD) assessment test (CAT) are the measures used to assess health status. This study aims to examine the responsiveness of these tools by severity of dyspnoea category in patients with COPD. Forty-nine COPD patients who underwent a 12-week pulmonary rehabilitation (PR) programme were assessed at baseline, 12 weeks and at 28-week follow-up. Patients were categorized into two groups by severity of dyspnoea category (i.e. mild to moderate (modified Medical Research Council (mMRC) 1–2) and severe to very severe (mMRC 3–4)) using the mMRC dyspnoea scale. Effect size (ES) was computed as estimates of responsiveness. The SGRQ demonstrated greater responsiveness by total sample (SGRQ, ES = 0.87; CAT, ES = 0.75) and for the mMRC 3–4 category (SGRQ, ES = 0.91; CAT, ES = 0.76) on completion of PR. At 28-week follow-up, overall comparable responsiveness of the CAT and SGRQ was identified by total sample (SGRQ, ES = 0.75; CAT, ES = 0.74) and by severity of dyspnoea category. The symptom, impact and activity domains of the SGRQ showed good responsiveness, with greater ESs obtained overall for the mMRC 3–4 category. On completion of PR, the SGRQ demonstrates a greater responsiveness with COPD patients, especially in relation to the mMRC 3–4 category, while both the CAT and SGRQ show comparable responsiveness on follow-up.

Evaluation of individual quality of life among hemodialysis patients: nominated themes using SEIQoL-adapted

BACKGROUND

Quality of life (QoL) has become an important issue for patients with chronic renal failure diseases who are permanently undergoing hemodialysis. In this study, an adapted schedule for the evaluation of individual quality of life (SEIQoL-adapted) was used to evaluate QoL among hemodialysis patients, to explore their views about the most important aspects of life satisfaction.

METHODS AND RESULTS

A multiple approach design and convenience sampling were applied to recruit 53 patients from a hemodialysis unit in Iran. Data were collected through structured interviews and then analyzed using conventional content analysis. A total score for QoL was calculated using scale guideline. The most important aspects of life were health, family, financial status, living conditions, leisure activities, relationships and socializing, religious and spiritual issues, medical knowledge, and therapies or treatments. The calculated mean QoL score was 66.2, indicating a relatively high life satisfaction. Males had higher QoL scores than females in both married and single groups. Moreover, the relationships between the QoL scores and education, job and marital status were not statistically significant.

CONCLUSION

The SEIQoL-adapted revealed reasonable lay definitions of QoL in a group of patients following chronic renal failure. The patients' views of the aspects of life could be used by health policy makers, clinicians, and caregivers as a reliable guide to the most important priorities for treatment and medical interventions.

Enzyme replacement therapy for Anderson-Fabry disease

BACKGROUND

Anderson-Fabry disease is an X-linked defect of glycosphingolipid metabolism. Progressive renal insufficiency is a major source of morbidity, additional complications result from cardio- and cerebro-vascular involvement. Survival is reduced among affected males and symptomatic female carriers.This is an update of a Cochrane review first published in 2010, and previously updated in 2013.

OBJECTIVES

To evaluate the effectiveness and safety of enzyme replacement therapy compared to other interventions, placebo or no interventions, for treating Anderson-Fabry disease.

SEARCH METHODS

We searched the Cystic Fibrosis and Genetic Disorders Group's Inborn Errors of Metabolism Trials Register (date of the most recent search: 08 July 2016). We also searched 'Clinical Trials' on The Cochrane Library, MEDLINE, Embase and LILACS (date of the most recent search: 24 September 2015).

SELECTION CRITERIA

Randomized controlled trials of agalsidase alfa or beta in participants diagnosed with Anderson-Fabry disease.

DATA COLLECTION AND ANALYSIS

Two authors selected relevant trials, assessed methodological quality and extracted data.

MAIN RESULTS

Nine trials comparing either agalsidase alfa or beta in 351 participants fulfilled the selection criteria.Both trials comparing agalsidase alfa to placebo reported on globotriaosylceramide concentration in plasma and tissue; aggregate results were non-significant. One trial reported pain scores measured by the Brief Pain Inventory severity, there was a statistically significant improvement for participants receiving treatment at up to three months, mean difference -2.10 (95% confidence interval -3.79 to -0.41; at up to five months, mean difference -1.90 (95% confidence interval -3.65 to -0.15); and at up to six months, mean difference -2.00 (95% confidence interval -3.66 to -0.34). There was a significant difference in the Brief Pain Inventory pain-related quality of life at over five months and up to six months, mean difference -2.10 (95% confidence interval -3.92 to -0.28) but not at other time points. Death was not an outcome in either of the trials.One of the three trials comparing agalsidase beta to placebo reported on globotriaosylceramide concentration in plasma and tissue and showed significant improvement: kidney, mean difference -1.70 (95% confidence interval -2.09 to -1.31); heart, mean difference -0.90 (95% confidence interval -1.18 to -0.62); and composite results (renal, cardiac, and cerebrovascular complications and death), mean difference -4.80 (95% confidence interval -5.45 to -4.15). There was no significant difference between groups for death; no trials reported on pain.Only two trials compared agalsidase alfa to agalsidase beta. One of them showed no significant difference between the groups regarding adverse events, risk ratio 0.36 (95% confidence interval 0.08 to 1.59), or any serious adverse events; risk ratio 0.30; (95% confidence interval 0.03 to 2.57).Two trials compared different dosing schedules of agalsidase alfa. One of them involved three different doses (0.2 mg/kg every two weeks; 0.1 mg/kg weekly and; 0.2 mg/kg weekly), the other trial evaluated two further doses to the dosage schedules: 0.4 mg/kg every week and every other week. Both trials failed to show significant differences with various dosing schedules on globotriaosylceramide levels. No significant differences were found among the schedules for the primary efficacy outcome of self-assessed health state, or for pain scores.One trial comparing agalsidase alfa to agalsidase beta showed no significant difference for any adverse events such as dyspnoea and hypertension.The methodological quality of the included trials was generally unclear for the random sequence generation and allocation concealment.

AUTHORS' CONCLUSIONS

Trials comparing enzyme replacement therapy to placebo show significant improvement with enzyme replacement therapy in regard to microvascular endothelial deposits of globotriaosylceramide and in pain-related quality of life. There is, however, no evidence identifying if the alfa or beta form is superior or the optimal dose or frequency of enzyme replacement therapy. With regards to safety, adverse events (i.e., rigors, fever) were more significant in the agalsidase beta as compared to placebo. The long-term influence of enzyme replacement therapy on risk of morbidity and mortality related to Anderson-Fabry disease remains to be established. This review highlights the need for continued research into the use of enzyme replacement therapy for Anderson-Fabry disease.

Effects of a Problem-Based Learning Rehabilitation Programme on Quality of Life in Patients with Coronary Artery Disease

Background: The aim of cardiac rehabilitation (CR) is not only physical improvement but also increased quality of life (QoL). A CR programme based upon problem based learning (PBL) philosophy was developed, to achieve and apply new knowledge related to coronary artery disease (CAD). The aim of this paper was to evaluate the impact of the PBL programme on QoL.

Methods: 207 consecutive patients < 70 years of age with a recent event of CAD were randomised to a PBL group ( n = 104) or a control group ( n = 103). In addition to standard treatment, the PBL patients participated in 13 group sessions during 1 year, where individual learning needs and behavioural changes were focused upon. QoL was measured by the Ladder of Life, Self-Rated Health (SRH), SF 36, and Cardiac Health Profile (CHP).

Results: Significant differences between the groups, favouring the PBL patients, were found by global instruments: more optimistic expectations of the future QoL and a better general condition. No differences were found by SRH, SF 36 or subscales of CHP, but QoL increased in both groups during the year.

Conclusions: The main outcome was that QoL improved in both groups with some effects favouring the PBL programme.

Investigating Six-Month Health Outcomes of Patients with Angina Discharged from a Chest Pain Service

Hospital admissions for patients with suspected cardiac chest pain are increasing. The development of a chest pain service allows rapid diagnosis, investigation and treatment. Since the in-patient stay is often short, there is limited time for education and risk factor management. Little is known about the patients' recovery post discharge. This study was completed to investigate the 6-month health outcomes of 57 patients discharged from the chest pain service by measuring cardiovascular symptoms and risk profiles, mood and quality of life, adherence to secondary prevention, morbidity and mortality. The results of this study showed that 58% of the sample still suffered angina, 72% reported breathlessness, and 79% reported lethargy. Assessment of mood showed that 76% suffered from anxiety and 78% depression. Quality of life was impaired. A reduction of cholesterol level was the only significant change in risk factors. Secondary prevention measures showed that there was still room for improvement. Twenty-five percent of the sample was readmitted to hospital due to their cardiac condition. Patients had an average of eight contacts with their general practitioner, four of which were cardiac related. The ongoing symptoms, anxiety and depression and uncorrected risk factors can impact on their recovery. Currently, however, no programme of rehabilitation is available for angina patients, despite the potential for up to 30% of patients suffering a subsequent cardiac event (Ghandi et al., British Heart Journal 73 (1995) 193–198). This study suggests the need to develop, implement and evaluate a CR programme in this client group.

Individualized quality of life of severely affected multiple sclerosis patients: practicability and value in comparison with standard inventories

PURPOSE

Individualized quality of life (QoL) measures differ from traditional inventories in that QoL domains/weights are not predetermined, but identified by the individual. We assessed practicability of the Schedule for the Evaluation of Individual QoL-Direct Weighting (SEIQoL-DW) interview in severely affected multiple sclerosis (MS) patients; the key QoL dimensions identified; and the correlation of the SEIQoL-DW index score with standard patient-reported outcome measures (PROMs).

METHODS

Participants were people with severe MS who performed the baseline visit of the PeNSAMI trial (ISRCTN73082124). The SEIQoL-DW was administered at the patient's home by a trained examiner. Patients then received the following PROMs: the Core-Palliative care Outcome Scale (Core-POS), the Palliative care Outcome Scale-Symptoms-MS (POS-S-MS), the European Quality of Life Five Dimensions-3L (EQ-5D-3L), and the Hospital Anxiety and Depression Scale (HADS).

RESULTS

Of 59 enrolled patients, 11 (19 %) did not receive the SEIQoL-DW (and the other PROMs) because of severe cognitive compromise or inability to communicate. SEIQoL-DW administration was completed and deemed valid in all 48 cases (mean age 60 years, 58 % women, median Expanded Disability Status Scale score 8.5). Mean SEIQoL-DW index score was 59.1 (SD 25.5). The most commonly nominated SEIQoL-DW areas were family (94 % of the patients), relationships, and leisure activities (both 65 %). Core-POS and POS-S-MS contained 70 % of the SEIQoL-DW-nominated areas. Nevertheless, correlations between SEIQoL-DW index, Core-POS, and POS-S-MS (and the other PROMs) were negligible.

CONCLUSIONS

Individualized QoL can be assessed in severely affected MS patients, providing information that is not tracked by the standard inventories Core-POS, POS-S-MS, EQ-5D-3L, and HADS.

Quality of life after aortic valve repair is similar to Ross patients and superior to mechanical valve replacement: a cross-sectional study

Background

In patients after aortic valve surgery, the quality of life is hypothesized to be influenced by the type of the valve procedure. A cross-sectional study on the postoperative quality of life was carried out in patients after aortic valve-sparing surgery (with regards to the age of the patient), Ross procedure and mechanical aortic valve replacement.

Methods

Quality of life was studied in 139 patients after aortic valve surgery divided into four study groups (Y – aortic valve-sparing procedure at the age below 50 years, mean age 36.2 years; O – aortic valve-sparing procedure at the age 50 years and over, mean age 59.2 years; R – Ross procedure, mean age 37.8 years and M – mechanical aortic valve replacement at the age below 50 years, mean age 39.2 years). SF-36 Short Form and valve-specific questionnaires were mailed to the patients after 6 months or later following surgery (median 26.9 months).

Results

In SF-36, the younger aortic valve repair patients and the Ross patients scored significantly better in 4 of 4 physical subscales and in 2 of 4 mental subscales than the older aortic valve repair and mechanical valve replacement patients. In the valve-specific questionnaire; however, all 3 groups free of anticoagulation (Y, O, and R) displayed greater freedom from negative valve-related concerns.

Conclusions

Postoperative quality of life is influenced by the type of aortic valve procedure and is negatively linked with mechanical prosthesis implantation and long-term anticoagulation. Aortic valve-sparing strategy should be considered in cases with suitable valve morphology due to favorable clinical results and beneficial impact on the long-term quality of life.

Predictors of subjective health status 10 years post-PCI

Background

Subjective health status is an increasingly important parameter to assess the effect of percutaneous coronary intervention (PCI) in clinical practice.

Aim of this study was to determine medical and psychosocial predictors of poor subjective health status over a 10 years' post-PCI period.

Methods

We included a series of consecutive PCI patients (n = 573) as part of the RESEARCH registry, a Dutch single-center retrospective cohort study.

Results

These patients completed the 36-item Short-Form Health Survey (SF-36) at baseline and 10 years post-PCI. We found 6 predictors of poor subjective health status 10 years post-PCI: SF-36 at baseline, age, previous PCI, obesity, acute myocardial infarction as indication for PCI, and diabetes mellitus (arranged from most to least numbers of sub domains).

Conclusions

SF-36 scores at baseline, age, and previous PCI were significant predictors of subjective health status 10 years post-PCI. Specifically, the SF-36 score at baseline was an important predictor. Thus assessment of subjective health status at baseline is useful as an indicator to predict long-term subjective health status. Subjective health status becomes better by optimal medical treatment, cardiac rehabilitation and psychosocial support. This is the first study determining predictors of subjective health status 10 years post-PCI.

Health-related quality of life in premature acute coronary syndrome: does patient sex or gender really matter?

Background

Limited data exist as to the relative contribution of sex and gender on health‐related quality of life (HRQL) among patients with acute coronary syndrome (ACS). This study aims to evaluate the effect of sex and gender‐related variables on long‐term HRQL among young adults with ACS.

Methods and Results

GENESIS‐PRAXY (GENdEr and Sex determInantS of cardiovascular disease: from bench to beyond‐Premature Acute Coronary SYndrome) is a multicenter, prospective cohort study (January 2009 to August 2013) of adults aged 18 to 55 years, hospitalized with ACS. HRQL was measured at baseline, 1, 6, and 12 months using the Short Form‐12 and Seattle Angina Questionnaire (SAQ) among 1213 patients. Median age was 49 years. Women reported worse HRQL than men over time post‐ACS, both in terms of physical and mental functioning. Gender‐related factors were more likely to be predictors of HRQL than sex. Femininity score, social support, and housework responsibility were the most common gender‐related predictors of HRQL at 12 months. We observed an interaction between female sex and social support (β=0.44 [95% confidence interval, 0.01, 0.88]; P=0.047) for the physical limitation subscale of the SAQ.

Conclusions

Young women with ACS report significantly poorer HRQL than young men. Gender appears to be more important than sex in predicting long‐term HRQL post‐ACS. Specific gender‐related factors, such as social support, may be amenable to interventions and could improve the HRQL of patients with premature ACS.

The Significance of Importance: An Evaluation of Ferrans and Powers’ Quality of Life Index

Ferrans and Powers' Quality of Life Index (QLI) defines and assesses quality of life (QoL) in terms of importance-weighted life satisfaction. This study assessed the value of such weights and explored the relationship between weighted and unweighted (satisfaction only) scores and single-item rated overall life satisfaction (LS) and QoL. Data were collected by a postal survey to 81 Parkinson's disease patients (88% response rate). Correlations between weighted and unweighted QLI scores were >or=0.96, except for one subscale (r ( s ) = 0.85). Item non-response rates ranged between 4.2 and 45.1% and 1.4 and 38% for the weighted and unweighted QLI, respectively. Cronbach's alpha exceeded 0.7 for weighted and unweighted versions of two out of the four subscales and the total score. Scaling success rates were similar for weighted and unweighted scores and did not support the current subscale structure. Unexpectedly, weighted total scores correlated stronger with LS than with QoL, and unweighted scores displayed the opposite pattern. This study found no advantages by using importance-weighted satisfaction scores. The correlational pattern with overall LS and QoL challenges the QLI approach to QoL, although these observations may relate to the use of multiplicative item weights. This study has implications also beyond the QLI regarding, e.g., the use of multiplicative weights and the relationship between life satisfaction and QoL.

Enzyme replacement therapy for Anderson-Fabry disease

BACKGROUND

Anderson-Fabry disease is an X-linked defect of glycosphingolipid metabolism. Progressive renal insufficiency is a major source of morbidity, additional complications result from cardio- and cerebro-vascular involvement. Survival is reduced among affected males and symptomatic female carriers.

OBJECTIVES

To evaluate the effectiveness and safety of enzyme replacement therapy compared to other interventions, placebo or no interventions, for treating Anderson-Fabry disease.

SEARCH METHODS

We searched 'Clinical Trials' on The Cochrane Library, MEDLINE, EMBASE, LILACS and the Cystic Fibrosis and Genetic Disorders Group's Inborn Errors of Metabolism Trials Register (date of the most recent search: 11 September 2012). The original search was performed in September 2008.Date of the most recent search of the Cystic Fibrosis and Genetic Disorders Group's Inborn Errors of Metabolism Trials Register: 11 September 2012.

SELECTION CRITERIA

Randomized controlled trials of agalsidase alfa or beta in participants diagnosed with Anderson-Fabry disease.

DATA COLLECTION AND ANALYSIS

Two authors selected relevant trials, assessed methodological quality and extracted data.

MAIN RESULTS

Six trials comparing either agalsidase alfa or beta in 223 participants fulfilled the selection criteria.Both trials comparing agalsidase alfa to placebo reported on globotriaosylceramide concentration in plasma and tissue; aggregate results were non-significant. One trial reported pain scores, there was a statistically significant improvement for participants receiving treatment at up to three months, mean difference -2.10 (95% confidence interval (CI) -3.79 to -0.41); at up to five months, mean difference -1.90 (95% CI -3.65 to -0.15); and at up to six months, mean difference -2.00 (95% CI -3.66 to -0.34). There was a significant difference in pain-related quality of life at over five months and up to six months, mean difference -2.10 (95% CI -3.92 to -0.28) but not at other time-points. Neither trial reported deaths.One of the three trials comparing agalsidase beta to placebo reported on globotriaosylceramide concentration in plasma and tissue and showed significant improvement: kidney, mean difference -1.70 (95% CI -2.09 to -1.31); heart, mean difference -0.90 (95% CI -1.18 to -0.62); and composite results (renal, cardiac, and cerebrovascular complications and death), mean difference -4.80 (95% CI -5.45 to -4.15). There was no significant difference between groups for death; no trials reported on pain.Only one trial compared agalsidase alfa to agalsidase beta. There was no significant difference between the groups for any adverse events, risk ratio 0.36 (95% CI 0.08 to 1.59), or any serious adverse events; risk ratio 0.30; 95% CI 0.03 to 2.57).

AUTHORS' CONCLUSIONS

Six small, poor quality randomised controlled trials provide no robust evidence for use of either agalsidase alfa and beta to treat Anderson-Fabry disease.

[Measurement of health-related quality of life in coronary heart disease: a review]

This paper introduces the development and application of health-related quality of life (HRQOL) scales in research on coronary heart disease (CHD). Currently, the scales for CHD patients have been more systematically developed and widely used in foreign countries, while domestically in China, they are developed successfully but problematically; research in this field has started later and the scales introduced are limited and not suitable for the entire range of domestic CHD patients. Thus, this paper introduces 26 HRQOL scales in research on CHD, including five generic scales, ten disease-specific scales from abroad and eleven scales originating from China. With the deficiency of HRQOL scales, especially that in traditional Chinese medicine and specific scales, this paper analyzes and summarizes the problems existing in development of scales. The authors also provide solutions in order to help the development and application of scales in further studies.

Contributors to individual quality of life after liver transplantation

BACKGROUND

With increasing improvements of patient survival after liver transplantation, the focus on outcome measures shifts from survival rate to quality of life. Individual quality of life is crucial to rehabilitate patients after transplantation. Therefore, it is important to identify specific issues that contribute to high individual quality of life. In contrast to the Short form 36 Health Survey (SF-36), the Schedule for the Evaluation of Individual aspects of Quality of Life-direct weighting (SEIQoL-DW) allows patients to name the areas of life, which are important to them.

DESIGN

In a semi-structured interview style, 71 patients following liver transplant were asked to complete the SEIQoL-DW and the SF-36 in a cross-sectional design.

RESULTS

We found five quality of life areas that were chosen by more than half of the patients: family, friends, sports, partnership and profession/occupation. Health was only mentioned by 45% of all patients. Individual quality of life did not differ from healthy population. In the SF-36, patients showed normal mental health parameters but reduced physical components. A strong correlation between SEIQoL-DW-Index and the mental component summary of the SF-36 was observed.

CONCLUSION

In addition to the widely used standardized SF-36, the individual measure SEIQoL-DW shows new aspects concerning the areas of quality of life, which are personally important to the participants. Less than half of our patients mentioned health and the five most nominated areas are not related to health. By focusing on health, the importance of health-related factors is overrated, and the impact of non-medical effects is underrepresented.

Aging, prospective memory, and health-related quality of life in HIV infection

HIV infection and older age are each independently associated with lower health-related quality of life (HRQoL) and deficits in prospective memory (PM), which is a distinct aspect of cognition involving the ability to "remember to remember" to do something at a future occasion. The present study investigated associations between PM and HRQoL in 72 older (≥ 50 years) and 41 younger (≤ 40 years) HIV-infected adults. Self-reported PM complaints predicted HRQoL across the entire sample, but there was a significant interaction between performance-based PM and age group on HRQoL, such that lower time-based PM was associated with lower HRQoL only in the younger cohort. Within the younger group, time-based and self-reported PM significantly predicted mental HRQoL independent of other risk factors (e.g. depression). These findings suggest that PM plays a unique role in HRQoL outcomes among younger persons living with HIV infection and support the examination of other age-related factors (e.g. effective use of compensatory strategies) that may regulate the adverse impact of PM on everyday functioning.

Obesity, health status, and 7-year mortality in percutaneous coronary intervention: in search of an explanation for the obesity paradox

BACKGROUND

Obesity is a growing health problem and is associated with adverse outcomes in coronary artery disease (CAD). However, recent studies have shown better survival in cardiovascular patients with overweight or obesity, which has been referred to as the "obesity paradox". As there is no clear understanding of the phenomenon, we examined the association between body mass index (BMI) and all-cause mortality in patients treated with percutaneous coronary intervention (PCI) at 7-year follow-up, and the potential role of health status in explaining the obesity paradox.

METHODS

Consecutive PCI patients (72.5% men; mean age 62.0 ± 11.2 years, range [27-90]years) from the Rapamycin-Eluting Stent Evaluated at Rotterdam Cardiology Hospital (RESEARCH) registry completed the 36-item short-form health survey (SF-36) to assess health status at baseline. Patients were classified into a normal weight, overweight or obesity group.

RESULTS

The prevalence of normal weight was 34.7% (354/1019), overweight was seen in 45.9% (468/1019) of patients, and 19.3% (197/1019) was obese. After a median follow-up of 7.0 ± 1.7 years, 163 deaths (16.0%) from any cause were recorded. Cumulative hazard functions differed significantly for the obese and overweight group when compared to the normal weight group (log-rank X(2)=6.59, p<0.05). In multivariable analysis, overweight, but not obesity, remained associated with a lower risk for all-cause mortality (HR=0.60, 95%CI [0.42-0.86], p=0.005). Additionally, after adding the 8 health status SF-36 domains to the multivariate model, the association between overweight and mortality remained unchanged.

CONCLUSION

In our study population overweight, but not obesity, was associated with a lower risk for 7-year mortality in PCI patients. Health status as measured with the SF-36 did not seem to play a role in explaining the obesity paradox.

The effect of early cardiac rehabilitation on health-related quality of life among heart transplant recipients and patients with coronary artery bypass graft surgery

PURPOSE

To investigate the effect of an early postoperative outpatient cardiac rehabilitation program to health-related quality of life among heart transplantation recipients (HTR) and patients with coronary artery bypass graft (CABG) surgery.

METHODS

The study included 45 clinically stable HTR (age: 47 ± 14 years; 36 men, 9 women) and 34 patients with CABG (age: 57.2 ± 12.5 years; 27 men, 7 women). HTR started rehabilitation 70 ± 33 days after transplantation; patients with CABG started training 36 ± 18 days after surgery. Patients participated in a 12-week supervised exercise training program three times per week. Each training session comprised 10 minutes of warm-up, 25 to 30 minutes of cycling or treadmill walking, and 10 minutes of cooldown. The exercise intensity was set at 50% to 80% of peak oxygen uptake (V̇O(2peak)) according to the patient's condition. The health-related quality of life of subjects was evaluated by the Medical Outcomes Trust 36-item health survey (SF-36) at baseline and upon the completion of rehabilitation.

RESULTS

At baseline, the HTR group showed lower V̇O(2peak) than the CABG group, but the health-related quality of life was similar between the two groups. After training, both groups exhibited an increase of 3.6 mL·kg(-1)·min(-1) in V̇O(2peak) and improvement of physical component in health-related quality of life. The HTR group showed a significant increase of SF-36 scores in physical functioning (59.7 ± 18.9 to 77.0 ± 14.0), physical role (21.1 ± 34.1 to 38.3 ± 37.9), bodily pain (57.4 ± 24.3 to 73.6 ± 21.5), social functioning (63.6 ± 23.4 to 72.8 ± 22.1), emotional role (59.2 ± 43.7 to 76.3 ± 37.4), and mental health (67.1 ± 17.9 to 73.4 ± 14.6). The CABG group only exhibited increased scores in physical functioning (60.0 ± 22.9 to 73.4 ± 18.0), physical role (19.1 ± 24.9 to 27.9 ± 38.3), bodily pain (57.1 ± 20.0 to 70.3 ± 16.1), and social functioning (54.0 ± 21.3 to 69.9 ± 21.1).

CONCLUSIONS

Early postoperative cardiac rehabilitation significantly improved physical capacity and quality of life among heart transplant recipients and patients with CABG. Additionally, HTR showed greater improvement in health-related quality of life than patients with CABG regardless of lower physical capacity.

Sense of coherence as an independent predictor of health-related quality of life among coronary heart disease patients

PURPOSE

The aim of this study was to determine whether sense of coherence (SOC) at baseline predicts health-related quality of life (HRQoL) at 12-28-month follow-up among patients with coronary heart disease when controlled for sociodemographic and medical variables.

METHODS

A total of 179 consecutive patients (58.28 ± 6.52 years, 16.8% women) scheduled for coronary angiography (CAG) were interviewed before CAG and 12-28 months after. SOC was measured with the 13-item Orientation to Life Questionnaire. HRQoL was measured using the Short Form Health Survey 36 (SF-36), from which the mental and physical component summaries (MCS, PCS) were calculated. The relationship between SOC and HRQoL was examined using regression analyses.

RESULTS

SOC proved to be a significant predictor of the MCS-score (B = 0.29; 95% CI = 0.17-0.41) and PCS-score (B = 0.18; 95% CI = 0.06-0.31) when not adjusted for possible confounding sociodemographic and medical variables. After adjustment for sociodemographic and medical variables, SOC remained a predictor of the MCS-score (B = 0.26; 95% CI = 0.14-0.39). SOC also remained a predictor of the PCS-score when controlled for gender, age and family income; however, the association disappeared after adjustment for functional status (B = 0.07; 95% CI = -0.05 to 0.19).

CONCLUSIONS

SOC is a predictor of mental and physical HRQoL at 12-28-month follow-up, crude and also after adjustment. Patients undergoing CAG with low SOC thus deserve particular attention in regard to the maintenance and improvement of their HRQoL.

Gender differences and determinants of health related quality of life in coronary patients: a follow-up study

Background

The role of gender differences in Health Related Quality Life (HRQL) in coronary patients is controversial, so understanding the specific determinants of HRQL in men and women might be of clinical importance. The aim of this study was to know the gender differences in the evolution of HRQL at 3 and 6 months after a coronary event, and to identify the key clinical, demographic and psychological characteristics of each gender associated with these changes.

Methods

A follow-up study was carried out, and 175 patients (112 men and 63 women) with acute myocardial infarction (AMI) or unstable angina were studied. The SF-36v1 health questionnaire was used to assess HRQL, and the GHQ-28 (General Health Questionnaire) to measure mental health during follow-up. To study the variables related to changes in HRQL, generalized estimating equation (GEE) models were performed.

Results

Follow-up data were available for 55 men and 25 women at 3 months, and for 35 men and 12 women at 6 months. Observations included: a) Revascularization was performed later in women. b) The frequency of rehospitalization between months 3 and 6 of follow-up was higher in women c) Women had lower baseline scores in the SF-36. d) Men had progressed favourably in most of the physical dimensions of the SF-36 at 6 months, while at the same time women's scores had only improved for Physical Component Summary, Role Physical and Social Functioning; e) the variables determining the decrease in HRQL in men were: worse mental health and angina frequency; and in women: worse mental health, history of the disease, revascularization, and angina frequency.

Conclusions

There are differences in the evolution of HRQL, between men and women after a coronary attack. Mental health is the determinant most frequently associated with HRQL in both genders. However, other clinical determinants of HRQL differed with gender, emphasizing the importance of individualizing the intervention and the content of rehabilitation programs. Likewise, the recognition and treatment of mental disorders in these patients could be crucial.

Quality of life after aortic valve surgery: replacement versus reconstruction

OBJECTIVE

Quality of life has been shown to be influenced by aortic valve replacement, particularly in younger patients. Aortic valve repair is a recent alternative to replacement. We investigated quality of life and anxiety and depression after aortic valve repair and compared with 2 established replacement alternatives, mechanical valve and pulmonary autograft.

METHODS

In a cross-sectional study, 166 patients (age, 18-45 years) were studied after isolated elective aortic valve surgery. They had undergone aortic valve repair (group I, n = 86), replacement with mechanical prosthesis (group II, n = 41), or pulmonary autograft (group III, n = 39). Assessment was performed by Short Form Health Survey, Hospital Anxiety and Depression Scale, Cardiac Anxiety Questionnaire, and valve-specific questions.

RESULTS

In Short Form Health Survey, groups I and III revealed similar or identical scores better than group II in physical functioning (P = .02), general health (P = .03), and mental health (P = .05). No differences were found in Hospital Anxiety and Depression Scale score. In cardiac anxiety, there was less heart-focused attention in groups I and III than in group II (P = .043, P = .053). In response to valve-specific questions, there were no differences between groups I and III. Interestingly, fear of reoperation was identical in all 3 groups.

CONCLUSIONS

In young patients after aortic valve surgery quality of life is influenced by type of operation. Although differences are limited, aortic valve reconstruction and pulmonary autograft replacement lead to less long-term alteration from normal values.

Individualized measurement of quality of life in older adults: development and pilot testing of a new tool

We describe theoretical background, development, and piloting of a measure for quality of life in older adults that specifically takes into account the subjective perspective. Although quality of life is usually subjectively assessed, normative thresholds for "the good life" are most often set by a third party. The new tool FLQM asks for respondents to name, rate, and weight those domains in life that are most important for their life-satisfaction solely from their own point of view. Construct validity was pilot-tested in two samples of elders (N₁ = 44; N₂ = 90). Correlations were in the medium range in both studies and support the questionnaire's validity. There were no age or gender differences on total score. However, in Study 1 as well as in Study 2 older subjects named significantly fewer domains than did younger participants. Further, in Study 1 the overall number of distinct domains generated by the participants diminished with age-the "interindividual pool of domains" shrank. Implications of this age-associated narrowing of domainscope are discussed on a background of adaptation theories. Concluding, the new questionnaire seems apt to assess older peoples' quality of life even in a physically very ill population, but needs further testing, especially regarding its reliability. This is currently being undertaken in a larger longitudinal sample to assure psychometric properties.

Reliability and Validity of the Dementia Quality of Life Measure in Nursing Home Residents

The purpose of this study was to test the reliability and validity of the Dementia Quality of Life (DQOL) in a sample of 486 residents from 12 nursing homes in the greater Baltimore area. There was some evidence of validity of the DQOL based on confirmatory factor analysis and Rasch model testing and criterion-related validity. Reliability of the DQOL was somewhat supported in this study based on internal consistency and test—retest reliability. Alpha coefficients and R2 estimations were generally low across all of the subscales. Despite these findings, the subscale scores remained consistent over a 12-month period. The use of the single-item question about QOL may not be an accurate reflection of QOL among nursing home residents. These findings provide additional information about the psychometric properties of the DQOL and offer some recommendations for revisions in the measure to optimally measure QOL in nursing home residents.

Enzyme replacement therapy for Anderson-Fabry disease

BACKGROUND

Anderson-Fabry disease is an X-linked defect of glycosphingolipid metabolism. Progressive renal insufficiency is a major source of morbidity, additional complications result from cardio- and cerebro-vascular involvement. Survival is reduced among affected males and symptomatic female carriers.

OBJECTIVES

To evaluate the effectiveness and safety of enzyme replacement therapy compared to other interventions, placebo or no interventions, for treating Anderson-Fabry disease.

SEARCH STRATEGY

We searched 'Clinical Trials' on The Cochrane Library, MEDLINE, EMBASE, LILACS and the Cystic Fibrosis and Genetic Disorders Group's Inborn Errors of Metabolism Trials Register (date of the most recent search: 07 April 2010).

SELECTION CRITERIA

Randomized controlled trials of agalsidase alfa or beta in participants diagnosed with Anderson-Fabry disease.

DATA COLLECTION AND ANALYSIS

Two authors selected relevant trials, assessed methodological quality and extracted data.

MAIN RESULTS

Five studies comparing either agalsidase alfa or beta in 187 participants fulfilled the selection criteria.Both trials comparing agalsidase alfa to placebo reported on globotriaosylceramide concentration in plasma and tissue; aggregate results were non-significant. One study reported pain scores, there was a statistically significant improvement for participants receiving treatment at up to three months, mean difference -2.10 (95% confidence interval (CI) -3.79 to -0.41); at up to five months, mean difference -1.90 (95% CI -3.65 to -0.15); and at up to six months, mean difference -2.00 (95% CI -3.66 to -0.34). There was a significant difference in pain-related quality of life at over five months and up to six months, mean difference -2.10 (95% CI -3.92 to -0.28) but not at other time-points. Neither study reported deaths.One of the three trials comparing agalsidase beta to placebo reported on globotriaosylceramide concentration in plasma and tissue and showed significant improvement: kidney, mean difference -1.70 (95% CI -2.09 to -1.31); heart, mean difference -0.90 (95% CI -1.18 to -0.62); and composite results (renal, cardiac, and cerebrovascular complications and death), mean difference -4.80 (95% CI -5.45 to -4.15). There was no significant difference between groups for death; no studies reported on pain.

AUTHORS' CONCLUSIONS

Five small, poor quality randomised controlled trials provide no robust evidence for use of either agalsidase alfa and beta to treat Anderson-Fabry disease.

The experience of using the SEIQoL-DW with patients with advanced chronic obstructive pulmonary disease (COPD): issues of process and outcome

PURPOSE

To report the experience of using the SEIQoL-DW for the measurement of quality of life with patients with advanced COPD and consider its feasibility, acceptability and appropriateness for a Phase III randomised controlled trial (RCT).

METHODS

The SEIQoL-DW was administered according to its instructions within a Phase II RCT 3-5 times per patient, across 13 patients and the process audio-recorded. Quantitative and qualitative criteria were used to assess feasibility, acceptability and appropriateness. Qualitative analysis of the transcripts and fieldwork notes was conducted using Framework Analysis.

RESULTS

The SEIQoL-DW steps (of identifying five quality of life cues, rating their functioning and importance) were completed at 48/51 interviews. However, some respondents were overwhelmed by the scripted introduction, experienced difficulty with cue identification, and focused only on certain types of cues (Step 1); some had difficulty interpreting and rating the concept of Step 2; and some had difficulty interpreting 'importance' and manipulating the SEIQoL-DW disc (Step 3).

CONCLUSIONS

Patients with advanced COPD were able to complete the SEIQoL-DW but analysis of its administration identified practical and conceptual concerns which question the validity of the results obtained. Suggestions for the development of the SEIQoL-DW and future feasibility studies are given.

The impact of Type D personality on health-related quality of life in tinnitus patients is mainly mediated by anxiety and depression

OBJECTIVE

To evaluate the impact of Type D personality on health-related quality of life (HRQoL) and self-reported tinnitus-related distress in chronic tinnitus patients and whether this relationship is mediated by indicators of psychological distress (i.e., vital exhaustion, anxiety, and depression).

MATERIALS AND METHODS

Using a cross-sectional study design, 265 consecutive tinnitus patients were asked to complete the Hospital Anxiety and Depression Scale, the Maastricht Questionnaire, the Type D Scale (DS14), the Short-Form Health Survey 36, and the Tinnitus Reaction Questionnaire.

RESULTS

The prevalence of Type D was 35.5%. Type D patients were significantly more anxious, depressed, and vitally exhausted, and experienced more impaired HRQoL and increased tinnitus-related distress compared with non-Type D patients. Structural equation modeling showed that Type D personality directly increased symptoms of depression and anxiety, but not vital exhaustion. Type D was also a direct predictor of poor mental and physical HRQoL and increased tinnitus-related distress, although this influence was mainly mediated by symptoms of depression and anxiety. Anxiety, depression, and vital exhaustion had a direct influence on HRQoL and self-reported tinnitus-related distress, with a higher impact on mental HRQoL (R2 = 0.74) compared with physical HRQoL (R2 = 0.33). Vital exhaustion was a predictor of HRQoL and self-reported tinnitus-related distress; however, its influence was moderated by enhanced levels of anxiety and depression.

CONCLUSION

Tinnitus patients with a Type D personality were more likely to be anxious and depressed and to experience poor HRQoL and increased self-reported tinnitus-related distress, with the impact of Type D mainly being mediated by symptoms of anxiety and depression, although Type D also exerted a direct influence on these outcomes. These findings underline that to reduce the impact of tinnitus on HRQoL and self-reported tinnitus-related distress, treatment should be directed toward reducing anxiety and depression, especially in patients with a Type D personality.

Health-related quality of life and long-term mortality in patients treated with percutaneous coronary intervention

BACKGROUND

Health status has become increasingly important as an outcome measure in patients with cardiovascular disease. Poor patient-rated health status has been shown to predict mortality in patients with coronary artery disease and heart failure. In patients treated with percutaneous coronary intervention (PCI), we examined whether poor health status predicts 6-year mortality and whether a decline in health status is associated with adverse clinical outcome.

METHODS

Consecutive patients (N = 872) treated with PCI as part of the RESEARCH registry, completed the 36-item Short-Form Health Survey (SF-36) at 1 and 12 months post-PCI.

RESULTS

The SF-36 domains physical functioning (hazard ratio [HR] 2.59, 95% CI 1.61-4.16), social functioning (HR 2.76, 95% CI 1.74-4.37), role limitations due to physical functioning (HR 2.45, CI 1.52-3.92), mental health (HR 2.12, 95% CI 1.35-3.31), vitality (HR 1.73, 95% CI 1.09-2.74), bodily pain (HR 2.25, 95% CI 1.43-3.54), and general health (HR 2.46, 95% CI 1.57-3.87) were associated with 6-year mortality. A decline in health status was not related with higher 6-year mortality.

CONCLUSIONS

Health status domains as measured with the SF-36 predicted death at 6-year follow-up in PCI patients treated with drug-eluting stenting, independent of demographic and clinical characteristics. In contrast, a decline in health status between 1 and 12 months post index procedure, as measured with the SF-36, was not associated with 6-year mortality in PCI patients treated with drug-eluting stenting.

The Impact of Anemia on Nursing Home Residents

The purpose of this secondary data analysis was to describe the prevalence and treatment of anemia and test the impact of anemia on physical and psychosocial outcomes at baseline and following restorative care interventions. A total of 451 residents from 12 nursing homes participated in this study. The average age of the participants was 83.74 ( SD = 8.24), the majority were female (79%), White (66%), and unmarried (90%). A total of 245 (54%) residents were anemic, and 66% were treated with at least one medication. Physical performance was worse in those with anemia, and those with anemia associated with chronic kidney disease had lower self-efficacy and outcome expectations for functional activities than those without anemia. There was no time by treatment interaction between those with and without anemia. The findings provide some additional support for the prevalence of anemia and suggest that those with anemia associated with chronic kidney disease are less motivated to engage in functional activities.

Somatically ill persons' self-nominated quality of life domains: review of the literature and guidelines for future studies

OBJECTIVE

To review which domains somatically ill persons nominate as constituting their QoL. Specific objective is to examine whether the method of enquiry affect these domains.

METHODS

We conducted two literature searches in the databases PubMed/Medline, CINAHL and Psychinfo for qualitative studies examining patients' self-defined QoL domains using (1) SEIQoL and (2) study-specific questions. For each database, two researchers independently assessed the eligibility of the retrieved abstracts and three researchers subsequently classified all QoL domains.

RESULTS

Thirty-six eligible papers were identified: 27 studies using the SEIQoL, and nine presenting data derived from study-specific questions. The influence of the method of enquiry on patients' self-nominated QoL domains appears limited: most domains were presented in both types of studies, albeit with different frequencies.

CONCLUSIONS

This review provides a comprehensive overview of somatically ill persons' self-nominated QoL domains. However, limitations inherent to reviewing qualitative studies (e.g., the varying level of abstraction of patients' self-defined QoL domains), limitations of the included studies and limitations inherent to the review process, hinder cross-study comparisons. Therefore, we provide guidelines to address shortcomings of qualitative reports amenable to improvement and to stimulate further improvement of conducting and reporting qualitative research aimed at exploring respondents' self-nominated QoL domains.

Quality of life and burden of spouses of Alzheimer disease patients

The objective of the study was to explore, in a sample of spouses of mild-to-moderate Alzheimer disease patients, predictors of quality of life (QoL) by rating QoL and burden. The authors assessed 97 spouses in a cross-sectional study with the Schedule for the Evaluation of Individual Quality of Life (SEIQoL), Self-Rated Burden scale (SRB), self-perceived stress scale (EDIZ; Ervaren Druk door Informele Zorg/Self-Perceived Pressure from Informal Care), and Zarit Burden Interview (ZBI). Patient cognition was rated with the Mini-Mental State Examination (MMSE). Factors best predicting QoL were analyzed with multiple regression analysis. Eighty-seven (53% male, mean 72 y) fulfilled the SEIQoL internal reliability criteria, and had a mean SEIQoL score of 68.6+/-14.8. Most important QoL domains were condition of patient (31%) and marriage (26%). Caregiver burden scores on SRB, Ervaren Druk door Informele, Zorg, and ZBI were 44.1+/-23.5 (n=67), 4.9+/-2.2 (n=53), and 13.1+/-6.2 (n=53), respectively. Mean patient MMSE score (0 to 30) was 20.3+/-4.2. Spouses experienced lower QoL than Alzheimer disease patients and healthy elderly (historical controls), and perceived moderate levels of burden. Patient cognition is a significant predictor of caregiver QoL. Burden, measured by ZBI, is significantly negatively correlated with SEIQoL. The results underline the importance of implementing health services known to improve QoL and alleviate burden, and to explore new effective interventions.

Prevalence and characteristics of multiple psychiatric disorders in cardiac rehabilitation patients

PURPOSE

Anxiety and depressive disorders have been established as independent risk factors for the development of and recovery from coronary heart disease (CHD). However, few studies have reported on the prevalence and personal characteristics of comorbid psychiatric disorders (PD) among cardiac populations. This project examined the prevalence of comorbid depressive and anxiety disorders among men and women with CHD commencing cardiac rehabilitation (CR) and the demographic, medical, and psychosocial characteristics among those meeting multiple PD criteria.

METHODS

Participants were 143 CHD patients (M age, 61 years; SD, 11.2; 70% men, 91% Caucasian, 64% married) entering CR who were evaluated via a semistructured, psychiatric interview to assess both current and lifetime prevalence rates of PD. Demographic, medical, and psychosocial variables were also assessed.

RESULTS

Approximately 45% met criteria for at least 1 anxiety disorder, and 20% met criteria for either major depressive disorder or dysthymic disorder either at the time of evaluation or in their lifetime. Across all participants, 26% met criteria for >or=2 PD. Of those with a depressive disorder, 76% also met criteria for at least 1 anxiety disorder. Participants with comorbid PD were of younger age and female and reported less education (P < .01). Comorbidity was also associated with self-reported overall diminished physical, emotional, and social quality of life, depression, and anxiety.

CONCLUSION

Comorbid PD are highly prevalent in the CR setting and are associated with specific demographic characteristics and reduced quality of life. These data offer additional support that routine screening for PD is warranted in outpatient cardiac settings.

Coronary artery bypass graft (CABG) surgery patients in a clinical pathway gained less in health-related quality of life as compared with patients who undergo CABG in a conventional-care plan

AIMS AND OBJECTIVES

The aim of this study is to determine the difference between clinical pathway (CP) and conventional care in terms of health-related quality of life (HRQoL) domains, depression and anxiety, as well as to determine the relative contribution of CP towards an improved HRQoL after coronary artery bypass graft (CABG).

METHOD

A longitudinal quasi-experimental pre-test/post-test design was used to study and compare clinical outcome, HRQoL depression and anxiety for CP versus conventional-care patients after CABG. HRQoL was measured by using Sf-36, while depression and anxiety were measured by using hospital anxiety and depression scale. Length of stay and patient complications were derived from the hospital database.

RESULTS

We found that implementing a CP decreased hospital delay from 2.50 (+/-7.19) to 1.80 (+/-1.60), which was statistically significant P = 0.002. We also found that patients in the conventional-care plan improved more than patients in the CP in HRQoL. Outcomes in favour of patients in the conventional-care trajectory were based on the difference between small effect sizes (ES) (> or =0.20 <0.50) for pathway patients and moderate ES (> or =0.50 <0.80) for conventional-care patients, except for the domain of physical functioning and physical component summary, where the ES for conventional care was large (>0.80).

CONCLUSION

The aim of designing and implementing pathways is to decrease length of stay and costs, while maintaining quality of care and improving patient outcomes. Our findings suggest that these aims were not fulfilled in this CABG pathway. We recommend that when designing a CP, all patient-related characteristics, risk indicators, along with physiological status, be taken into consideration.
