Measuring health-related quality of life in older patient populations: a review of current approaches

Change in quality of life of medically hospitalized patients--a one-year follow-up study

OBJECTIVES

To examine changes in quality of life (QOL) among elderly medically hospitalized patients one year after hospitalization, and to explore factors associated with the changes.

METHODS

A one-year follow-up study included 363 (175 men) medical inpatients with age range 65-98 (mean 80.2, SD 7.5) years. Information was collected at baseline and follow-up using the WHOQOL-BREF questionnaire assessing the physical, psychological, social and environment domain of QOL as the dependent variable, and the Mini-Mental State Examination, Lawton and Brody's scales for physical self-maintenance and instrumental activities of daily living, the Hospital Anxiety and Depression scale and assistance in living as the independent variables.

RESULTS

The mean score of the physical domain of QOL had increased (mean change 0.6, SD 2.5; p < 0.01); the mean score of the environmental domain had decreased (mean change -2.1, SD 1.2; p < 0.01); and, the mean scores of the psychological and social domains of QOL were unchanged (mean change -0.2, SD 1.8 and mean change -0.1, SD 1.5, respectively) at follow-up. Improved individual QOL at a one-year follow-up was associated with improved health (cognitively, physically and emotionally) after hospitalization, and with health situation at baseline. Being in need of assistance was associated with reduced QOL.

CONCLUSION

Good cognitive, physical and emotional health at baseline and follow-up were associated with improved QOL in previously hospitalized elderly patients independent of their need for assistance in living.

Quality of Life (QOL) and Its Associated Factors Using WHOQOL-BREF Among Elderly in Urban Puducherry, India

BACKGROUND

Quality of Life (QOL) among elderly is a neglected issue especially in developing countries including India.

AIM

To assess the QOL and its associated factors among elderly population.

MATERIALS AND METHODS

A community based cross-sectional study was conducted among 300 elderly subjects in urban Puducherry, India. Data on QOL was assessed by World Health Organization Quality of Life BREF (WHOQOL-BREF) and Activities of Daily Living (ADLs) by Katz ADL scale. Socio-demographic factors and chronic morbid conditions were recorded by using structured questionnaire.

STATISTICAL ANALYSIS

Independent sample test and multiple linear regression analysis.

RESULTS

Majority (64%, 192) were in the (60-69) years' age-group. Overall mean Standard Deviation (SD) score of QOL was 49.74 (10.21). QOL was significantly low among those with no schooling, nuclear family, not receiving pension, not with partner, having musculoskeletal disorder, low vision and impaired ADL groups in univariate analysis. Multiple linear regression analysis revealed that older age (p=0.014), no schooling (p=0.004), without spouse (p=<0.001), nuclear family (p=0.039), musculoskeletal disorder (p=<0.001), low vision (p=0.049) and hearing impairment (0.001) were associated with low QOL score.

CONCLUSION

QOL score among elderly is average, while social relationship domain of QOL score was found to be low. Health education with regard to activity and environmental changes and increase in social relationship may help in improving the QOL among the elderly population.

Transcatheter aortic valve implantation: restoring the qualities of life in old age

Transcatheter aortic valve implantation (TAVI) is a tremendous therapeutic advance for patients with severe aortic stenosis and high-surgical risk. Since TAVI-treated patients are elderly with multiple co-existing conditions, limited life expectancy and disproportionate health-care expenditures, the aspect of the health-related quality of life (HRQoL) benefits becomes of fundamental importance. Based on recent evidence, TAVI appears to improve significantly HRQoL measures compared with optimal standard care, which are restored to age-adjusted population norms over time.

[A new instrument to measure quality of life in older people: The French version of the WHOQOL-OLD]

PURPOSE

We present the validation data of the French version of a new quality of life questionnaire, specifically developed for use with older adults (>60 years old): the WHOQOL-OLD module. This questionnaire, which contains 24 items in six domains, is a complementary module of the WHOQOL-BREF quality of life questionnaire. It was internationally developed by a World Health Organization (WHO) group.

METHODS

The first development and pilot studies led to a first questionnaire applied in field studies in 20 centers all over the world. They were done in 5566 subjects and allowed the validation of the final form of the WHOQOL-OLD questionnaire. For its French version, 281 subjects, with a mean age of 74 years, were recruited in three centers (Paris, Nancy and Geneva).

RESULTS

The results of the psychometric properties of the questionnaire, particularly the multitrait analysis, are compatible with the assumptions underlying the construction of scores. Otherwise, scores present a sufficient accuracy to use this instrument in group comparisons.

CONCLUSION

The WHOQOL-OLD questionnaire can be used in older people in health services, clinical research and epidemiologic studies.

Quality of life in older people: a structured review of self-assessed health instruments

A range of terms (including quality of life, health-related quality of life and health status) describe a broad set of aspects of self-reported health that can be captured by questionnaires and related instruments. Health in older people particularly requires attention to broader aspects of the impact of health on physical, social and psychological function. A structured review was performed to assess how well such issues are measured by available instruments. A total of 45 instruments were identified that have received some degree of evaluation to establish their use in assessing the health of older individuals. Two types of instruments were included in the review: generic and older-people-specific instruments. The SF-36 has by far the largest evidence base to support its use in older people. The OMFAQ has the best evidence base amongst older-people-specific instruments. Many instruments have only minimal evidence of measurement properties. Concepts such as quality of life are still defined and used in a variety of ways, and major questions must be addressed before uniform practice emerges in this important area of health policy.

Assessing the impact of a restorative home care service in New Zealand: a cluster randomised controlled trial

Due to the ageing population, there is an increased demand for home care services. Restorative care is one approach to improving home care services, although there is little evidence to support its use in the community setting. The objective of this trial was to evaluate the impact of a restorative home care service for community-dwelling older people. The study was a cluster randomised controlled trial undertaken at a home care agency in New Zealand. The study period was from December 2005 to May 2007. Older people were interviewed face-to-face at baseline, four and 7 months. A total of 186 older people who received assistance from a home care agency participated in the study, 93 received restorative home care and 93 older people received usual home care. The primary outcome measure was change in health-related quality of life (measured by the Short Form 36 [SF36] Health Survey). Secondary outcomes were the physical, mental, and social well-being of older people (Nottingham Extended Activities of Daily Living, Timed Up and Go, Mastery scale, Duke Social Support Index). Findings revealed that compared with usual care, the intervention demonstrated a statistically significant benefit in health-related quality of life (SF36) at 7 months for older people (mean difference 3.8, 95% CI -0.0 to 7.7, P = 0.05). There were no changes in other scale measurements for older people in either group over time. There was a statistically significant difference in the number of older people in the intervention group identified for reduced hours or discharge (29%) compared with the control group (0%) (P < 0.001). In conclusion, a restorative home care service may be of benefit to older people, and improves home care service efficacy.

Vitamin D intake and mental health-related quality of life in older women: the Iowa Women's Health Study

OBJECTIVE

Vitamin D deficiency and mood disorders are both prevalent among the elderly. We evaluated the association between vitamin D intake and mental health-related quality of life (QOL) among elderly women participating in a large population-based study.

STUDY DESIGN

This study was a cross-sectional analysis of the Iowa Women's Health Study, a prospective study of cancer risk factors among post-menopausal women in Iowa that began in 1986. Additional survey data was collected from the cohort members in 1987, 1989, 1992, 1997, and 2004. Data for this analysis came from the 2004 questionnaire.

MAIN OUTCOME MEASURE

Mental health-related QOL was assessed using five scales from the Medical Outcomes Study 36-item Short-form Health Survey. QOL scores were analyzed as continuous variables using linear regression, controlling for age, energy intake, BMI, education, smoking, living arrangement, antidepressant usage, comorbidity history, and physical activity.

RESULTS

Low vitamin D intake (<400 IU/day) was associated with poorer QOL scores compared to women with higher intake (≥400 IU/day). Differences in QOL scores by vitamin D intake group were attenuated with multivariable adjustment, but a significant overall association between vitamin D and QOL scores persisted. Further adjustment for physical activity attenuated all differences as well as the overall association between vitamin D and QOL scores.

CONCLUSIONS

Women who consumed <400 IU/day of vitamin D had significantly lower mental health-related QOL compared to those who consumed ≥400 IU/day. Meeting dietary vitamin D recommendations is a potential method for improving QOL among the elderly.

Medication use and functional status decline in older adults: a narrative review

BACKGROUND

Functional status is the cornerstone of geriatric care and serves as an indicator of general well-being. A decline in function can increase health care use, worsen quality of life, threaten independence, and increase the risk of mortality. One of several risk factors for decline in functional status is medication use.

OBJECTIVE

Our aim was to critically review published articles that have examined the relationship between medication use and functional status decline in the elderly.

METHODS

The MEDLINE and EMBASE databases were searched for English-language articles published from January 1986 to June 2011. Search terms included aged, humans, drug utilization, polypharmacy, inappropriate prescribing, anticholinergics, psychotropics, antihypertensives, drug burden index, functional status, function change or decline, activities of daily living, gait, mobility limitation, and disability. A manual search of the reference lists of the identified articles and the authors' article files, book chapters, and recent reviews was conducted to retrieve additional publications. Only articles that used rigorous observational or interventional designs were included. Cross-sectional studies and case series were excluded from this review.

RESULTS

Nineteen studies met the inclusion criteria. Five studies addressed the impact of suboptimal prescribing on function, 3 of which found an increased risk of worse function in community-dwelling subjects receiving polypharmacy. Three of the 4 studies that assessed benzodiazepine use and functional status decline found a statistically significant association. One cohort study identified no relationship between antidepressant use and functional status, whereas a randomized trial found that amitriptyline, but not desipramine or paroxetine, impaired certain measures of gait. Two studies found that increasing anticholinergic burden was associated with worse functional status. In a study of hospitalized rehabilitation patients, users of hypnotics/anxiolytics (eg, phenobarbital, zolpidem) had lower relative Functional Independence Measure motor gains than nonusers. Use of multiple central nervous system (CNS) drugs (using different definitions) was linked to greater declines in self-reported mobility and Short Physical Performance Battery (SPPB) scores in 2 community-based studies. Another study of nursing home patients did not report a significant decrease in SPPB scores in those taking multiple CNS drugs. Finally, 2 studies found mixed effects between antihypertensive use and functional status in the elderly.

CONCLUSIONS

Benzodiazepines and anticholinergics have been consistently associated with impairments in functional status in the elderly. The relationships between suboptimal prescribing, antidepressants, and antihypertensives and functional status decline were mixed. Further research using established measures and methods is needed to better describe the impact of medication use on functional status in older adults.

Assessment of patients with neck pain: a review of definitions, selection criteria, and measurement tools

OBJECTIVE

The purpose of this literature review was to synthesize the existing literature on various definitions, classifications, selection criteria, and outcome measures used in different studies in patients with neck pain.

METHODS

A literature search of MEDLINE and CINAHL through September 2008 was performed to gather articles on the reliability, validity, and utility of a wide variety of outcome measurements for neck pain.

RESULTS

Different types of definitions appear in the literature based on anatomical location, etiology, severity, and duration of symptoms. Classifications according to severity and duration of pain and the establishment of selection criteria seem to play a crucial role in study designs and in clinical settings to ensure homogeneous groups and effective interventions. A series of objective tests and subjective self-report measures are useful in assessing physical abilities, pain, functional ability, psychosocial well-being, general health status, and quality of life in patients with neck pain. Self-administered questionnaires are commonly used in clinical practice and research projects.

CONCLUSIONS

Because of multidimensionality of chronic neck pain, more than just one index may be needed to gain a complete health profile of the patient with neck pain. The instruments chosen should be reliable, valid, and able to evaluate the effects of treatment.

Measuring health-related quality-of-life for Alzheimer's disease using the general public

PURPOSE

Little research exists to indicate whether the general public can provide proxy health-related quality-of-life (HRQoL) estimates for persons with Alzheimer's disease (AD). We investigated (1) whether the general public can differentiate between mild, moderate, and severe AD and (2) whether the general public's proxy HRQoL estimates are correlated with current health status.

METHODS

We conducted computer-assisted personal interviews. The computer randomly assigned each participant to read a vignette describing mild, moderate, or severe AD. Participants answered the EQ-5D-5L and Quality-of-life-Alzheimer's Disease (QoL-AD), while imagining living in the health state described in their assigned vignette. Participants also answered the EQ-5D-5L based on their health state at the time of the interview.

RESULTS

We interviewed 100 participants. EQ-5D-5L utilities were 0.7413 (mild), 0.6159 (moderate), and 0.4456 (severe) (P < 0.001). Mean QoL-AD scores were 32.5 (mild), 24.0 (moderate), and 21.8 (severe) (P < 0.0001 for severe vs. mild, moderate vs. mild; P > 0.05 for severe vs. moderate). Participants' EQ-5D-5L utility scores were weakly correlated (r ≤ 0.28) across both administrations of the instrument.

CONCLUSIONS

The general public can differentiate between the three stages of AD, and their HRQoL estimates for AD are weakly correlated with their current health status.

A comparison of life satisfaction in elderly medical inpatients and the elderly in a population-based study: Nord-Trondelag Health Study 3

AIM

To compare the quality of life (QOL) in terms of overall life satisfaction in elderly medical inpatients and elderly persons in a large population-based study in Norway, and to study the odds for dissatisfaction, controlling for demographic, health, and social variables.

METHODS

This cross-sectional observation study included 484 medical inpatients and 10,474 persons from the Nord-Trøndelag Health Study 3 (HUNT 3 Study). All participants were 65 years and older. Their life satisfaction was assessed with a single-item measure with seven response categories. For analytical purposes the variable was dichotomised; i.e. dissatisfied vs. satisfied with life.

RESULTS

In the logistic regression analysis controlled for demographic, health, and social variables, the odds for experiencing dissatisfaction with life was significantly increased in the hospital sample compared to the participants in the population-based study (OR 1.4). Poor general health, depression, and anxiety were strongly associated with being dissatisfied with life. Furthermore, disability, previous psychological distress, having no friends who could help, and not participating in activities were all associated with dissatisfaction with life.

CONCLUSIONS

The hospitalisation of the elderly has implications for the QOL in terms of life satisfaction, but general physical and psychological health seems to have an even stronger impact on life satisfaction. The prevention of the deterioration of physical and mental health in old age seems to be essential for a good life.

Quality of life in elderly patients with acute myeloid leukemia: patients may be more accurate than physicians

BACKGROUND

The aim of this study was to evaluate changes in quality of life scores and their association with therapy and survival in unselected elderly patients with acute myeloid leukemia.

DESIGN AND METHODS

From February 2003 to February 2007, 113 patients aged more than 60 years with de novo acute myeloid leukemia were enrolled in a prospective observational study. Two different quality of life instruments were employed: the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire - C30 (EORTC QLQ-C30) and a health-related quality of life questionnaire for patients with hematologic diseases (QOL-E).

RESULTS

Forty-eight patients (42.4%) received intensive chemotherapy and 65 (57.6%) were given palliative treatments. Age greater than 70 years (P=0.007) and concomitant diseases (P=0.019) had a significant impact on treatment allocation. At diagnosis, general quality of life was affected [median QOL-E standardized score 54, interquartile range 46-70; median EORTC global score 50, interquartile range 41-66]. Most patients were given a good ECOG Performance Status (< 2), which did not correlate with the patients' perception of quality of life. At multivariate analysis, palliative approaches (P=0.016), age more than 70 years (P=0.013) and concomitant diseases (P=0.035) each had an independent negative impact on survival. In a multivariate model corrected for age, concomitant diseases and treatment option, survival was independently predicted by QOL-E functional (P=0.002) and EORTC QLQ-C30 physical function (P=0.030) scores.

CONCLUSIONS

Quality of life could have an important role in elderly acute myeloid leukemia patients at diagnosis as a prognostic factor for survival and a potential factor for treatment decisions.

Reference bias: presentation of extreme health states prior to EQ-VAS improves health-related quality of life scores. a randomised cross-over trial

BACKGROUND

Clinical practice and clinical research has made a concerted effort to move beyond the use of clinical indicators alone and embrace patient focused care through the use of patient reported outcomes such as health-related quality of life. However, unless patients give consistent consideration to the health states that give meaning to measurement scales used to evaluate these constructs, longitudinal comparison of these measures may be invalid. This study aimed to investigate whether patients give consideration to a standard health state rating scale (EQ-VAS) and whether consideration of good and poor health state descriptors immediately changes their self-report.

METHODS

A randomised crossover trial was implemented amongst hospitalised older adults (n = 151). Patients were asked to consider descriptions of extremely good (Description-A) and poor (Description-B) health states. The EQ-VAS was administered as a self-report at baseline, after the first descriptors (A or B), then again after the remaining descriptors (B or A respectively). At baseline patients were also asked if they had considered either EQ-VAS anchors.

RESULTS

Overall 106/151 (70%) participants changed their self-evaluation by ≥ 5 points on the 100 point VAS, with a mean (SD) change of +4.5 (12) points (p < 0.001). A total of 74/151 (49%) participants did not consider the best health VAS anchor, of the 77 who did 59 (77%) thought the good health descriptors were more extreme (better) then they had previously considered. Similarly 85/151 (66%) participants did not consider the worst health anchor of the 66 who did 63 (95%) thought the poor health descriptors were more extreme (worse) then they had previously considered.

CONCLUSIONS

Health state self-reports may not be well considered. An immediate significant shift in response can be elicited by exposure to a mere description of an extreme health state despite no actual change in underlying health state occurring. Caution should be exercised in research and clinical settings when interpreting subjective patient reported outcomes that are dependent on brief anchors for meaning.

Evidence of disagreement between patient-perceived change and conventional longitudinal evaluation of change in health-related quality of life among older adults

Objective: To identify agreement levels between conventional longitudinal evaluation of change (post—pre) and patient-perceived change (post—then test) in health-related quality of life.

Design: A prospective cohort investigation with two assessment points (baseline and six-month follow-up) was implemented.

Setting: Community rehabilitation setting.

Subjects: Frail older adults accessing community-based rehabilitation services.

Intervention: Nil as part of this investigation.

Main measures: Conventional longitudinal change in health-related quality of life was considered the difference between standard EQ-5D assessments completed at baseline and follow-up. To evaluate patient-perceived change a ‘then test’ was also completed at the follow-up assessment. This required participants to report (from their current perspective) how they believe their health-related quality of life was at baseline (using the EQ-5D). Patient-perceived change was considered the difference between ‘then test’ and standard follow-up EQ-5D assessments.

Results: The mean (SD) age of participants was 78.8 (7.3). Of the 70 participants 62 (89%) of data sets were complete and included in analysis. Agreement between conventional (post—pre) and patient-perceived (post—then test) change was low to moderate (EQ-5D utility intraclass correlation coefficient (ICC) = 0.41, EQ-5D visual analogue scale (VAS) ICC = 0.21). Neither approach inferred greater change than the other (utility P =0.925, VAS P =0.506). Mean (95% confidence interval (CI)) conventional change in EQ-5D utility and VAS were 0.140 (0.045,0.236) and 8.8 (3.3,14.3) respectively, while patient-perceived change was 0.147 (0.055,0.238) and 6.4 (1.7,11.1) respectively.

Conclusions: Substantial disagreement exists between conventional longitudinal evaluation of change in health-related quality of life and patient-perceived change in health-related quality of life (as measured using a then test) within individuals.

Low morale is associated with increased risk of mortality in the elderly: a population-based prospective study (NEDICES)

OBJECTIVE

the study aimed to assess the association between morale and mortality.

DESIGN

we used data from the Neurological Disorders in Central Spain (NEDICES), a population-based study.

SUBJECTS

2,516 older persons (mean age 75.7 years) participated in the study.

METHODS

Cox models were used to estimate risk of mortality. Morale was assessed using the Philadelphia Geriatric Center Morale Scale.

RESULTS

489 (21.8%) participants died over a median follow-up of 5.9 years (range 0.1-7.7 years), including 253 (21.8%) deaths among 1,163 participants with low morale scores, 168 (19.3%) among 870 participants with moderate scores and 68 (14.1%) among participants with high scores. In an unadjusted Cox model, relative risk (RR) of mortality in participants with low morale scores = 1.69 (P < 0.001) and RR in participants with moderate scores = 1.47 (P < 0.01) were compared to the reference group (participants with high scores). In a Cox model that adjusted for a variety of demographic factors and co-morbidities, RR of mortality in participants with low morale scores = 1.35 (P <0.05) and moderate scores = 1.16 (not significant) were compared to the reference group.

CONCLUSION

low morale may be an independent predictor of mortality in the elderly. By assessing morale, practitioners might be better positioned to identify patients with poorer prognoses.

Trajectories of quality of life in older persons with advanced illness

OBJECTIVES

To examine subjective ratings of quality of life (QoL) in older adults with advanced illness.

DESIGN

Observational cohort study with interviews at least every 4 months for up to 2 years conducted between December 1999 and December 2002.

SETTING

Participants' homes.

PARTICIPANTS

One hundred eighty-five community-dwelling individuals aged 60 and older with advanced cancer, heart failure, or chronic obstructive pulmonary disease.

MEASUREMENTS

Participants were asked how they would rate their overall QoL.

RESULTS

Of participants who died, 46% reported good or best possible QoL at their final interview, 21% reported improvement in QoL from their penultimate to final interview, and 39% reported no change. Forty-nine percent of participants reported two or more changes in the direction of their QoL trajectories (e.g., QoL improved then declined). As measured over time in a multivariable longitudinal regression analysis, greater activity of daily living disability (adjusted odds ratio (AOR)=0.85, 95% confidence interval (CI)=0.75-0.95) and depressed mood (AOR=0.42, 95%CI=0.27-0.66) were associated with poorer QoL, whereas better self-rated health (AOR=4.79, 95% CI=2.99-7.69) and having grown closer to one's church (AOR=1.99, 95% CI=1.17-3.39) were associated with better QoL.

CONCLUSION

Although declining QoL is not an inevitable consequence of advancing illness, individuals' ratings of QoL are highly variable over time, suggesting that temporary factors may influence subjective QoL. Functional status, depression, and connection to one's religious community are shared determinants of QoL.

Patient-reported outcomes after cytotoxic chemotherapy in metastatic castration-resistant prostate cancer: a systematic review

BACKGROUND

In the clinical setting of metastatic castration-resistant prostate cancer the aim of treatment is palliation. Palliation can refer to symptom management or non-curative treatments. Patient-reported outcome is any outcome based on data provided by patients. The aim of this paper is to perform a systematic review of clinical trials including a patient-reported outcome assessment in patients treated with cytotoxic chemotherapy, and to compare their results by traditional medical and patient-reported outcomes assessment.

METHODS

In November 2009 a literature search for published studies was undertaken. Selected phase-3 studies were primarily evaluated on the quality of patient-reported outcomes reporting and assessment methodology.

FINDINGS

Health-related quality of life assessment was the most common endpoint, pain control the second one. Results of patient-reported and traditional endpoints analysis are resumed, as well as methodology assessment and quality of patient-reported outcomes reporting. Frequently, methodologic limitations affect patient-reported outcomes assessment in clinical trials, either data analysis, particularly not reporting individual scores of health-related quality of life questionnaires, statistical corrections, limited efforts to avoid missing data, or lacking report of duration of palliative response.

CONCLUSIONS

Results of trials can differ if different outcomes, medical or patient-reported, are considered in the analysis. Cytotoxic chemotherapy of metastatic castration-resistant prostate cancer is a challenging issue. A survival benefit is reported only for docetaxel, but this treatment is not always feasible. In all patients, initiation of chemotherapy should be based on patient's preferences within discussion of individual risk and benefit, particularly in patients with extensive asymptomatic and symptomatic metastases.

Sex differences in the relative contribution of social and clinical factors to the Health Utilities Index Mark 2 measure of health-related quality of life in older home care clients

Background

The heterogeneity evident among home care clients highlights the need for greater understanding of the clinical and social determinants of multi-dimensional health-related quality of life (HRQL) indices and of potential sex-differences in these determinants. We examined the relative contribution of social and clinical factors to HRQL among older home care clients and explored whether any of the observed associations varied by sex.

Methods

The Canadian-US sample included 514 clients. Self-reported HRQL was measured during in-home interviews (2002-04) using the Health Utilities Index Mark 2 (HUI2). Data on clients' sociodemographic, health and clinical characteristics were obtained with the Minimum Data Set for Home Care. The relative associations between clients' characteristics and HUI2 scores were examined using multivariable linear regression models.

Results

Women had a significantly lower mean HUI2 score than men (0.48, 95%CI 0.46-0.50 vs. 0.52, 0.49-0.55). Clients with distressed caregivers and poor self-rated health exhibited significantly lower HRQL scores after adjustment for a comprehensive list of clinical conditions. Several other factors remained statistically significant (arthritis, psychiatric illness, bladder incontinence, urinary tract infection) or clinically important (reported loneliness, congestive heart failure, pressure ulcers) correlates of lower HUI2 scores in adjusted analyses. These associations generally did not vary significantly by sex.

Conclusion

For females and males, HRQL scores were negatively associated with conditions predictive or indicative of disability and with markers of psychosocial stress. Despite sex differences in the prevalence of social and clinical factors likely to affect HRQL, few varied significantly by sex in their relative impact on HUI2 scores. Further exploration of differences in the relative importance of clinical and psychosocial well-being (e.g., loneliness) to HRQL among female and male clients may help guide the development of sex-specific strategies for risk screening and care management.

Telephone reliability of the Frenchay Activity Index and EQ-5D amongst older adults

Background

Older adults may find it problematic to attend hospital appointments due to the difficulty associated with travelling to, within and from a hospital facility for the purpose of a face-to-face assessment. This study aims to investigate equivalence between telephone and face-to-face administration for the Frenchay Activities Index (FAI) and the Euroqol-5D (EQ-5D) generic health-related quality of life instrument amongst an older adult population.

Methods

Patients aged >65 (n = 53) who had been discharged to the community following an acute hospital admission underwent telephone administration of the FAI and EQ-5D instruments seven days prior to attending a hospital outpatient appointment where they completed a face-to-face administration of these instruments.

Results

Overall, 40 subjects' datasets were complete for both assessments and included in analysis. The FAI items had high levels of agreement between the two modes of administration (item kappa's ranged 0.73 to 1.00) as did the EQ-5D (item kappa's ranged 0.67–0.83). For the FAI, EQ-5D VAS and EQ-5D utility score, intraclass correlation coefficients were 0.94, 0.58 and 0.82 respectively with paired t-tests indicating no significant systematic difference (p = 0.100, p = 0.690 and p = 0.290 respectively).

Conclusion

Telephone administration of the FAI and EQ-5D instruments provides comparable results to face-to-face administration amongst older adults deemed to have cognitive functioning intact at a basic level, indicating that this is a suitable alternate approach for collection of this information.

Association of bone and joint diseases with health-related quality of life among older people: a population-based cross-sectional study in rural Bangladesh

This study examined the cross-sectional association of bone and joint diseases with health-related quality of life (HRQoL) among 850 randomly sampled people aged 60 or more years in a rural area of Bangladesh. Information about arthritis, back and joint pain was collected through self-reports and two physicians' assessments at a health centre. Health-related quality of life was measured using a multi-dimensional generic instrument designed for older people that has questions on the construct's physical, psychological, social, economic, spiritual and environmental dimensions. Bivariate analyses showed that the most negative effects of bone and joint diseases were on the physical and psychological dimensions. Hierarchical linear regression analyses revealed that joint pain, whether doctor-diagnosed or self-reported, and self-reported back pain were all associated with lower HRQoL scores and accounted for almost 20 per cent of the variation (adjusted for age, sex, education, marital status, household size, income, expenditure and occupation). The analyses further revealed that women with self-reported back pain had significantly lower psychological, environmental and overall HRQoL scores than equivalent men, while self-reported joint pain was associated with significantly lower scores only for the environmental dimension. The strong association of bone and joint diseases with HRQoL underscores the importance of regarding these illnesses as public health problems.

Additional impact of concomitant hypertension and osteoarthritis on quality of life among patients with type 2 diabetes in primary care in Germany - a cross-sectional survey

Background

Patients with type 2 diabetes are likely to have comorbid conditions which represent a high burden for patients and a challenge for primary care physicians. The aim of this cross-sectional survey was to assess the impact of additional comorbidities on quality of life within a large sample of patients with type 2 diabetes in primary care.

Methods

A cross-sectional survey within a large sample (3.546) of patients with type 2 diabetes in primary care was conducted. Quality of life (QoL) was assessed by means of the Medical Outcome Study Short Form (SF-36), self reported presence of comorbid conditions was assessed and groups with single comorbidities were selected. QoL subscales of these groups were compared to diabetes patients with no comorbidities. Group comparisons were made by ANCOVA adjusting for sociodemographic covariates and the presence of depressive disorder.

Results

Of 3546 questionnaires, 1532 were returned, thereof 1399 could be analysed. The mean number of comorbid conditions was 2.1. 235 patients declared to have only hypertension as comorbid condition, 97 patients declared to have osteoarthritis only. Patients suffering from diabetes and hypertension reached similar scores like diabetic patients with no comorbidities. Patients with diabetes and osteoarthritis reached remarkable lower scores in all subscales. Compared to patients with diabetes alone these differences were statistically significant in the subscales representing pain and physical impairment.

Conclusion

The impact of osteoarthritis as an often disabling and painful condition on QoL in patients with type 2 diabetes is higher than the impact of hypertension as common but often asymptomatic comorbidity. Individual care of patients with chronic conditions should aim at both improving QoL and controlling risk factors for severe complications.

Quality-of-life Assessment of Family Planning Adopters through User Perspectives in the District of Karimnagar

BACKGROUND

Small families adopting family planning are usually considered happy families. They are expected to lead a better qualitative life. Quality-of-life (QOL) is routinely assessed for knowing patients' health status. Recently, the QOL concept has become increasingly popular for evaluating the impact of public health interventions. Hitherto, QOL is usually assessed by means of program achievements or indicators, which may sometimes be misleading. Hence, the new culture of QOL assessment by means of user perspectives is now becoming popular.

RESEARCH QUESTIONS

1) Is the quality-of-life of family planning (FP) adopters better than that of non-FP adopters? 2) Are the user perspectives helpful in QOL assessment?

MATERIALS AND METHODS

A cross-sectional descriptive study was carried out among 50 FP adopting families and 50 non-FP adopting families from the village of Vutoor and the city of Karimnagar in Andhra Pradesh. SAMPLING METHODS: Random sampling, Proportions and Chi square test.

RESULTS

Program perspectives revealed a better standard of living for FP adopters because they have amenities like housing, television, and vehicles and less mortality and morbidity (P < 0.001). However, they lack positive feelings towards life, general adaptation, personal relationships, and leisure opportunities. Finally, self-assessment by FP adopters themselves revealed no significant increase in their qualitative life after family planning (P = 0.05).

CONCLUSIONS

While assessing the impact of a health program on quality-of-life, multiple methods of assessments including user perspectives are better than program indicators alone.

Profile of adults with congenital heart disease having a good, moderate, or poor quality of life: a cluster analytic study

AIMS

The purpose of the study was to assess the profile of adult patients with congenital heart disease who reported a good, moderate, or poor quality of life.

METHODS

We conducted a secondary analysis of data from a large-scale quality-of-life study that included 627 patients. Demographic and clinical variables were retrieved from the medical records and functional status from patient interviews. Overall quality of life was measured using a Linear Analogue Scale. Using K-means cluster analysis, we categorized subjects into a 3-cluster solution: good, moderate, or poor quality of life.

RESULTS

Four hundred ninety patients (78.1%) clustered into the good quality-of-life category; 126 patients (20.1%) clustered into the moderate quality-of-life category; and 11 patients (1.8%) clustered into the poor quality-of-life category. Poorer quality of life was associated with lower educational level, unemployment or disability, associated syndromes, instability of the heart disease, and a poorer functional status.

CONCLUSION

Over three-quarters of the patients had a good quality of life, whereas only a small proportion had a poor quality of life. Specific demographic and clinical characteristics associated with a poor quality of life could assists in identifying patients at risk for developing a poor quality of life.

Quality of life and patient-reported outcomes in the older breast cancer patient

As the world population ages, the incidence of cancer will probably also increase as it is a disease predominantly affecting older people. However, those aged 70 years or more have largely been excluded from clinical trials. This review focuses on breast cancer. Increasingly there is recognition that many older breast cancer patients are being undertreated and could and should be offered the same treatments as younger patients. Comprehensive assessment of the quality of any survival benefit from treatments is also needed to ensure that in the future older patients can make fully informed decisions about their treatment options. The aim of this overview is two-fold: first to describe methods by which to assess quality of life; and second to review the recent surgical, radiotherapy, chemotherapy and other studies that include such assessment with older breast cancer patients. Current studies are also outlined, including quality of life assessments, and recommendations are made for future research in this area.

A systematic review of the use and validation of health-related quality of life instruments in older cancer patients

AIM

The aim of this paper is to systematically review the use and validation of HRQOL instruments in older cancer patients.

METHOD

A systematic review of 5 databases and 3 research registers identified studies reporting the use and validation of HRQOL instruments in cancer patients aged over 65 years from 1995 to mid 2007.

RESULTS

Thirty-one studies reported the use of HRQOL measures in older people, using a range of generic and disease-specific instruments. Little work was reported in patients aged over 80 years. All studies exhibited methodological limitations. Fourteen studies were identified with variable evidence on the psychometric properties and clinical usefulness of identified instruments.

CONCLUSION

Our review identified that the development, validation and use of HRQOL instruments often ignore the specific needs of older people. This review highlights the need for a HRQOL instrument specifically designed to capture the issues and concerns most relevant to older cancer patients.

Prospects and challenges in using patient-reported outcomes in clinical practice

BACKGROUND

Patient-reported measures include preferences and reports about care received, health behaviors, and outcomes of care (patient satisfaction and health-related quality of life). These measures are a core aspect of health care, but there is much to be learned about how to use them to improve clinical practice.

METHOD

We specify linkages among different patient-reported measures and focus upon the prospects and challenges for use of patient-reported outcomes in clinical practice.

RESULTS

Patient-reported measures are important throughout the continuum of patient care. At the initial visit, patient-reported outcomes provide information about what is important to the patient, the patient's current behaviors, and the patient's baseline health-related quality of life. At subsequent visits, patient-reported outcomes help evaluate disease progression or regression as well as treatment effects.

CONCLUSIONS

Patient-reported measures can help clinicians target interventions that will improve patient outcomes of care. However, there are a number of challenges in using patient-reported outcomes in clinical practice.

Clinimetric properties of 3 instruments measuring postoperative recovery in a gynecologic surgical population

BACKGROUND

General, health-related quality-of-life questionnaires and recovery-specific questionnaires have been used to measure recovery in surgical patients. The aim of this study was to evaluate the clinimetric properties of 3 recovery instruments and to examine whether recovery-specific instruments are useful.

METHODS

The Quality of Recovery-40 (QoR-40), Recovery Index-10 (RI-10), and RAND-36 health survey were used to measure recovery in women undergoing different types of hysterectomy in the first 12 weeks after operation. Construct validity was assessed by testing predefined hypotheses. The changes observed during the postoperative period were used as indicators for responsiveness.

RESULTS

One hundred and sixty-one women were included. Response rate and internal consistency were found satisfactory. The highest number of hypotheses used for assessment of construct validity was confirmed in the RI-10. The RI-10 was more responsive compared with the QoR-40 and the RAND-36.

CONCLUSIONS

Because construct validity and responsiveness were greatest in the RI-10, we conclude that this short recovery-specific instrument is useful in studies evaluating postoperative recovery. We recommend the use of the RI-10, unless the immediate postoperative days are of interest in which the QoR-40 was valid.

Patient and caregiver quality of life in Huntington's disease

Little is known about subjective perceptions of quality of life (QOL) in Huntington's disease (HD). The current study determined correlates of patient and caregiver QOL and assessed change over time. Participants were 22 patient-caregiver dyads, who rated QOL at baseline and 6 months later. Overall, patients' functional and cognitive impairment were significantly correlated with patient and caregiver QOL. Neuropsychiatric symptoms had differential impact on patient and caregiver QOL. Furthermore, when patients recalled their QOL about a previous time, their recall may have been negatively biased. Clinical implications of results are discussed. Future work is needed because subjective QOL is an important outcome measure in therapeutic trials.

Patient-reported outcomes: instrument development and selection issues

At its most elemental, patient-reported outcomes (PRO) assessment involves asking the patients questions and evaluating their answers. Instrument developers need to be clear about what they want to know, from whom they want to know it and why, whether what they learned is credible, and whether they can interpret what they learned in the context of the research objectives. Because credible instrument development is neither inexpensive nor technically trivial, researchers must first determine that no available measure meets their research objectives. We suggest that the tasks of either reviewing current instruments or developing new ones originate from the same basic premise: PRO assessment requires a well-articulated conceptual framework. Once defined in the context of the research objectives, the conceptual framework needs to be adapted to the population of interest. We discuss how qualitative methods enrich the conceptual framework and facilitate the technical measurement tasks of item development, testing, and reduction. We recognize that PRO assessment stands at a technological crossroads with the increasingly frequent application of "modern" psychometric methods and discuss how innovations such as item banks and computer-adaptive testing will influence PRO instrument development. Although items are the essential building blocks for instruments, scales are the primary unit of analysis for PRO assessment, and we discuss methods for scoring and combining them. Finally, PRO assessment is meaningless if the key figure chooses not to cooperate. We consider how respondent burden influences the quality of PRO assessment.

Sex differences in quality of life in stroke survivors: data from the Tinzaparin in Acute Ischaemic Stroke Trial (TAIST)

BACKGROUND AND PURPOSE

Female sex is predictive of poor functional outcome in stroke, even after correction for prognostic factors. Poor quality of life (QoL) is observed in stroke survivors with lower scores seen in the most disabled patients. We used data from the Tinzaparin in Acute Ischaemic Stroke Trial (TAIST) to assess the relationship between sex and QoL after ischemic stroke.

METHODS

TAIST was a randomized, controlled trial assessing the safety and efficacy of tinzaparin versus aspirin in 1484 patients with acute ischemic stroke. QoL was measured at 180 days postrandomization using the Short Form-36 health survey, which assesses QoL across 8 domains. The relationship between sex and each domain was assessed using ordinal regression, both unadjusted and adjusted for key prognostic factors.

RESULTS

Of the 1484 patients randomized into TAIST, 216 had died at 180 days postrandomization. A total of 1268 survivors were included in this analysis, 694 males (55%) and 574 females (45%). Females tended to score lower than males across all QoL domains (apart from general health); statistically significant lower scores were seen for physical functioning (OR: 0.58, 95% CI: 0.47 to 0.72), vitality (OR: 0.79, 95% CI: 0.64 to 0.98), and mental health (OR: 0.75, 95% CI: 0.61 to 0.93). The results for physical functioning and mental health remained significant after adjustment for prognostic variables (OR: 0.73, 95% CI: 0.58 to 0.92; OR: 0.76, 95% CI: 0.60 to 0.95, respectively).

CONCLUSIONS

QoL, in particular physical function and mental health domains, is lower in female patients after stroke. This difference persists even after correction for known prognostic factors such as age and stroke severity.

Quality-of-life in elderly patients with cancer: a short review

BACKGROUND

Prolongation of survival and maintenance or improvement of health-related quality-of-life (HRQoL) are the two important goals within the treatment of individual patients. Due to the severity of symptoms and the toxicity of treatment, HRQoL has become a major area of concern when treating cancer patients in general and elderly patients in particular.

PATIENTS AND METHODS

We present a literature review of HRQoL aspects in elderly patients with cancer and especially address the topic whether impairments in the different tools of a comprehensive geriatric assessment (CGA) are associated with decreased HRQoL in elderly cancer patients.

RESULTS

Elderly cancer patients tend to weight their HRQoL as more important than gain in survival, when compared to younger patients. An age-dependent decrease in different scales of HRQoL is reported in patients and normative samples. HRQoL is also a predictor of survival. The variation of HRQoL can be used in trials comparing different treatment options. In individual patients, regular measurement of HRQoL aims to improve patients-centred care. Age related impairments of different areas of CGA are associated with decreased HRQoL in elderly cancer patients.

CONCLUSIONS

HRQoL is an important outcome with elderly cancer patients and should be assessed regularly and thoroughly.

A Primer on Health-Related Quality of Life in Chronic Pain Medicine

BACKGROUND

Pain is a complex and individual experience that is often difficult for patients to fully describe using a conventional pain intensity scale. Health-related quality of life is an additional metric by which to assess patients' subjective perspective on their chronic pain experience and its adverse effect on their lives. Health-related quality of life encompasses those aspects of health and well-being valued by patients, specifically, their physical, emotional, and cognitive function, and their ability to participate in meaningful activities within their family, workplace, and community.

METHODS

A methodical search of the medical literature was undertaken to identify the most commonly applied health-related quality of life measurement instruments. These measurement instruments were then assessed within the context of chronic pain medicine clinical practice and research.

RESULTS

This primer provides an overview of the concept of health-related quality of life as a clinical measurement and the specific means by which to measure health-related quality of life across various cultures in adults, as well as in children and adolescents, suffering from chronic pain conditions.

CONCLUSIONS

We have the ability and impetus to routinely assess adult and pediatric health-related quality of life in chronic pain medicine. However, further attention needs to be focused on overcoming barriers to the more widespread measurement of health-related quality of life. A valid preference-based, utility measure of health-related quality of life is a requirement for performing a cost-utility (cost-effectiveness) analysis and undertaking formal decision analysis modeling.
