Association between patient education and health-related quality of life in patients with Parkinson's disease

BACKGROUND: Providing patients with disease- and treatment-related information is an important role of medical staff and is now reimbursed in Japan by the national health insurance system under the rubric 'patient education'. Evaluation of the effectiveness of patient education programs is necessary to ensure that limited health care resources are used efficiently. OBJECTIVE: The objective is to determine whether educating patients with Parkinson's disease (PD) is related to better health-related quality of life (HRQOL). DESIGN: A cross-sectional study was conducted. SETTING: Members of the Japan Association of Patients with Parkinson's disease were randomly selected. PARTICIPANTS: A total of 1200 patients with PD were asked to fill in written questionnaires and replies from 762 (63.5%) were analyzed. MEASUREMENTS: The questionnaire inquired about clinical characteristics, comorbidity, symptoms of PD, complications of therapy, HRQOL, and patient education. SF-36 was used to assess HRQOL. The section on patient education comprised one question each on patient-perceived satisfaction with information provided on (1) disease condition and pathophysiology, (2) effectiveness of drug therapy, (3) adverse drug reactions, (4) publicly available financial and social resources, and (5) rehabilitation and daily activities. Patient education score was defined as the sum of the individual scores for these five questions. The relationships between scores on the SF-36 subscales and the patient education score were examined. RESULTS: More satisfaction with patient education was associated with higher scores in all SF-36 subscales except physical functioning and bodily pain. The difference in score between the most satisfied and the least satisfied patients ranged from 8.4 points on the subscales of general health and 16.7 points on the subscale of role limitation due to emotional problems. CONCLUSION: The conclusion that patient education is associated with better HRQOL in patients with PD is drawn.     

The relationship between insomnia and health-related quality of life in patients with chronic illness

OBJECTIVES: To determine the association between insomnia and health-related quality of life (HRQOL) in patients with chronic illness after accounting for the effects of depression, anxiety, and medical comorbidities. STUDY DESIGN: We used a cross-sectional analysis of Medical Outcomes Study (MOS) data. POPULATION: The sample consisted of 3445 patients who completed a self-administered questionnaire and who were given a diagnosis of 1 or more of 5 chronic medical and psychiatric conditions by an MOS clinician. Patients were recruited from the offices of clinicians practicing family medicine, internal medicine, endocrinology, cardiology, and psychiatry in 3 US cities. OUTCOMES MEASURED: Outcomes were sleep items, health-related quality of life as measured by the Medical Outcomes Study Short Form Health Survey (SF-36), chronic medical comorbidity, depression, and anxiety. Insomnia was defined as the complaint of difficulty initiating or maintaining sleep. RESULTS: Insomnia was severe in 16% and mild in 34% of study patients. Patients with insomnia demonstrated significant global decrements in HRQOL. Differences between patients with mild insomnia versus no insomnia showed small to medium decrements across SF-36 subscales ranging from 4.1 to 9.3 points (on a scale of 0 to 100); the corresponding decrements for severe insomnia (versus no insomnia) ranged from 12.0 to 23.9 points. CONCLUSIONS: Insomnia is independently associated with worsened HRQOL to almost the same extent as chronic conditions such as congestive heart failure and clinical depression.

Ethnic differences in the relationship between depressive symptoms and health-related quality of life in people with type 2 diabetes

Objective . To examine ethnic differences in the relationship between depressive symptoms and specific aspects of heath-related quality of life in people with type 2 diabetes.

Design . Cross-sectional data from 190 people with type 2 diabetes of Native Hawaiian (50%), Filipino (16%), Japanese (18%), and mixed-ethnic (16%) ancestries from the rural community of North Kōhala, Hawai‘i were examined in this study. Depressive symptoms were measured with the Center for Epidemiological Studies—Depression (CES-D) scale. Health-related quality of life was measured with the Short Form-36 Health Survey (SF-36). Eight health-related quality of life constructs were examined: Physical Functioning, Role-Physical Functioning, Role-Emotional Functioning, Social Functioning, Bodily Pain, Vitality, General Health, and Health Transition.

Results . Hierarchical regression analyses of the interaction between ethnicity and the SF-36 subscales of Physical Functioning, Role-Emotional Functioning, Bodily Pain, Vitality, and General Health indicated statistically significant associations with CES-D scores after controlling for sociodemographic factors, glycemic status, and social support.

Conclusion . Ethnicity moderated the relationship between depressive symptoms and the health-related quality of life aspects of physical and role-emotional functioning, bodily pain, vitality, and general health perception in people with type 2 diabetes. This relationship was strongest for Filipinos followed by Native Hawaiians and people of mixed-ethnic ancestries.     

Diabetic retinopathy and health-related quality of life among Chinese with known type 2 diabetes mellitus

Purpose

We aim to describe the impact of diabetic retinopathy (DR) on health-related quality of life (HRQOL) among community-dwelling Chinese adults who had been previously diagnosed with type 2 diabetes mellitus (T2DM).

Methods

A community-based survey including 913 patients with T2DM was conducted in Suzhou, China. Retinopathy lesions were graded according to the Airlie House classification system of the Early Treatment Diabetic Retinopathy Study. The HRQOL was measured by the Chinese version of the EuroQol Group’s five-level EuroQol five-dimensional questionnaire (EQ-5D-5L). A Gamma distribution with log link was incorporated into linear regression models to assess the associations between DR and EQ-5D-5L health utility score.

Results

The mean EQ-5D-5L index scores were 0.971?±?0.082 among individuals with unilateral DR and 0.970?±?0.145 among those with bilateral DR, which were lower compared with those without DR (0.986?±?0.045, P?=?0.02). In multivariate analysis adjusting for confounders, people with bilateral DR reported lower the EQ-5D index scores compared with those without DR. The presence of DR was significantly associated with problems in usual activities (odds ratio [OR]?=?0.16, P?=?0.02, comparing participants with unilateral vs. no DR; OR?=?0.11; P?=?0.01, comparing participants with bilateral vs. no DR). No significant variations in EQ-5D-5L index scores as well as different domains of health problems between individuals with unilateral and bilateral DR were observed (P?>?0.05).

Conclusion

Chinese T2DM patients with bilateral DR tend to report lower HRQOL scores compared with those without DR, especially in health problems associated with usual activities.

     

Published norms underestimate the health-related quality of life among persons with type 2 diabetes

Objective

To assess health-related quality of life (HRQL) among adults with type 2 diabetes using the Short Form (SF)-36 and to obtain pooled estimates of HRQL for subpopulations defined by demographic characteristics, diabetes-related complications, and comorbidities.

Study Design and Methods

We conducted computerized searches of multiple electronic bibliographic databases, and studies in any language were selected in which HRQL was reported among adults with type 2 diabetes using the SF-36. Estimates were combined using a random-effects model.

Results

One hundred eighteen studies fulfilled the inclusion criteria. HRQL was lower in persons with type 2 diabetes, as measured by all the eight component scores of the SF-36 when compared with the existing U.S. population norms and with previously published type 2 diabetes norms. SF-36 component and summary scores were extremely heterogeneous, and subpopulation data were sparse; this precluded obtaining meaningful pooled scores for most populations of interest and made comparisons among subpopulations difficult.

Conclusion

Our data suggest that previously published norms may underestimate the effect of diabetes on HRQL, and diabetes populations are extremely heterogeneous, making broad population “norms” for HRQL in type 2 diabetes of limited use. Additional research with important subpopulations and individual-level data are needed to further explore the effect of diabetes on HRQL.

The relationship between health-related quality of life and frequency of spells in patients with syncope

Chronic syncope has a wide range of symptom burden, and anecdotal data suggest substantial but variable physical and psychosocial morbidity. We hypothesized that health-related quality of life (HRQL) is impaired in syncope patients and the degree of impairment is proportional to syncope frequency. The EuroQol EQ-5D was completed by 136 patients (79 female and 57 male) with mean age 40 (SD = 17) prior to assessment. HRQL was substantially impaired in syncope patients compared to population norms in all five dimensions of health measured by the EQ-5D. In patients with six or more lifetime syncopal spells there was a significant (P < 0.001) negative relationship between the frequency of spells and overall perception of health, which was not evident in those who had a history of less than six lifetime spells. These relationships were maintained after controlling for comorbid conditions.

Social/economic costs and health-related quality of life in patients with Prader-Willi syndrome in Europe

Objective

The aim of this study was to determine the economic burden from a societal perspective and health-related quality of life (HRQOL) of patients with Prader-Willi syndrome (PWS) in Europe.

Methods

We conducted a cross-sectional study of patients with PWS from Spain, Bulgaria, Hungary, Germany, Italy, the UK, Sweden and France. Data on demographic characteristics, healthcare resource utilisation, informal care, labour productivity losses and HRQOL were collected from questionnaires completed by patients or their caregivers. HRQOL was measured with the EuroQol 5-domain (EQ-5D) questionnaire.

Results

A total of 261 patients completed the questionnaire. The average annual costs ranged from € 3937 to € 67,484 between countries; the reference year for unit prices was 2012. Direct healthcare costs ranged from € 311 to € 18,760, direct non-healthcare costs ranged from € 1269 to € 44,035, and loss of labour productivity ranged from € 0 to € 2255. Costs were also shown to differ between children and adults. The mean EQ-5D index score for adult PWS patients ranged between 0.40 and 0.81 and the mean EQ-5D visual analogue scale score ranged between 51.25 and 90.00.

Conclusion

The main strengths of this study lie in our bottom-up approach to costing and in the evaluation of PWS patients from a broad societal perspective. This type of analysis is very scarce in the international literature on rare diseases in comparison with other illnesses. We conclude that PWS patients incur considerable societal costs and experience substantial deterioration in HRQOL.

     

Physical activity and health-related quality of life: US adults with and without limitations

Purpose

The purpose of this study was to examine the dose–response relationship between physical activity (PA) and health-related quality of life (HRQOL) among adults with and without limitations.

Methods

We dichotomized HRQOL as ≥14 unhealthy (physical or mental) days (past 30 days), or <14 unhealthy days. By using a moderate-intensity minute equivalent, PA categories were as follows: inactive, 10–60, 61–149, 150–300, and >300 min/week. Persons with limitations reported having problems that limited their activities or required use of special equipment. Age-adjusted prevalence estimates and logistic regression analyses were performed with 2009 Behavioral Risk Factor Surveillance System data (n = 357,665), controlling for demographics, BMI, smoking, and heavy alcohol use.

Results

For adults without limitations, the odds of ≥14 unhealthy days were lower among adults obtaining any PA (10–60 min/week, AOR = 0.79, 95 % CI 0.70, 0.88), compared with those inactive. A quadratic trend (P < 0.001) indicated enhanced HRQOL with each PA level, but improvements were less marked between lower and upper sufficient PA categories (150-300 and >300 min/week). Because of a significant age interaction, persons with limitations were stratified by age (18–34, 35–64, and 65+ years). Findings for persons aged 35 years or older with limitations were similar to those without limitations. Lower odds of poor HRQOL for persons aged 18–34 years with limitations were associated with recommended levels of PA (150–300 min/week; AOR = 0.61, 95 % CI 0.43, 0.88 and >300 min/week; AOR = 0.58, 95 % CI 0.43, 0.80).

Conclusions

PA is positively associated with HRQOL among persons with and without limitations.

Comparison of self-reported health-related quality of life between Taiwan hemodialysis and peritoneal dialysis patients: a multi-center collaborative study

Purpose

The maintenance of good health-related quality of life (HRQoL) is an important goal for end-stage renal disease (ESRD) patients. Whether hemodialysis (HD) and peritoneal dialysis (PD) have different impacts on HRQoL is a concern shared by both physicians and patients. A comparison study of HRQoL between Taiwanese HD and PD patients was conducted.

Methods

ESRD patients at 14 hospitals or dialysis centers in northern Taiwan were recruited in this cross-sectional study. The Chinese-language version of the 36-item Short Form Health Survey Questionnaire (SF-36, Taiwan Standard Version 1.0) was used to evaluate HRQoL. Ordinal regression analyses were used to explore the independent association between HRQoL scores and dialysis modality. By Bonferroni correction test, a P value of <0.005 was regarded as significant.

Results

A total of 866 HD patients and 301 PD patients were included. After adjusting for confounding factors, no difference in HRQoL was found among the entire cohort and the diabetic subgroup.

Conclusion

This study demonstrated that Taiwanese HD and PD patients had similar HRQoL. The current survey improves our understanding of the association of HRQoL with dialysis modality in Taiwan ESRD population.
