Ethnic differences in health related quality of life for patients with type 2 diabetes

Health state utility values of type 2 diabetes mellitus and related complications: a systematic review and meta-regression

BACKGROUND

This study aimed to synthesize and quantitatively examine Health State Utility Values (HSUVs) for Type 2 Diabetes Mellitus (T2DM) and its complications, providing a robust meta-regression framework for selecting appropriate HSUV estimates.

METHOD

We conducted a systematic review to extract HSUVs for T2DM and its complications, encompassing various influencing factors. Relevant literature was sourced from a review spanning 2000-2020, supplemented by literature from PubMed, Embase, and the Web of Science (up to March 2024). Multivariate meta-regression was performed to evaluate the impact of measurement tools, tariffs, health status, and clinical and demographic variables on HSUVs.

RESULTS

Our search yielded 118 studies, contributing 1044 HSUVs. The HSUVs for T2DM with complications varied, from 0.65 for cerebrovascular disease to 0.77 for neuropathy. The EQ-5D-3L emerged as the most frequently employed valuation method. HSUV differences across instruments were observed; 15-D had the highest (0.89), while HUI-3 had the lowest (0.70) values. Regression analysis elucidated the significant effects of instrument and tariff choice on HSUVs. Complication-related utility decrement, especially in diabetic foot, was quantified. Age <70 was linked to increased HSUVs, while longer illness duration, hypertension, overweight and obesity correlated with reduced HSUVs.

CONCLUSION

Accurate HSUVs are vital for the optimization of T2DM management strategies. This study provided a comprehensive data pool for HSUVs selection, and quantified the influence of various factors on HSUVs, informing analysts and policymakers in understanding the utility variations associated with T2DM and its complications.

Patient-reported outcomes in diabetes-related foot conditions: Is patient experience influenced by ethnicity? A mixed-methods systematic review

AIMS

Research in diabetes-related foot conditions (DRFC) often focuses on ulcer-related care, whilst the patient experience and influence of sociodemographic factors are under-researched. This systematic review investigated patient-reported outcomes and experience in people with DRFC.

METHODS

Multiple databases were searched from inception to 16 August 2023. All original articles that assessed any patient-reported outcome or experience in DRFC and reported participant ethnicity were included. Data were synthesized using a sequential contingent approach. Study quality was assessed using study design-specific tools.

RESULTS

Twenty-three studies were included (11 qualitative, 11 quantitative and one mixed-methods). DRFC had a largely negative impact on various life dimensions, including social and daily life, work, emotional and psychological well-being, necessitating dependence on others in the form of emotional, social and/or religious support, which were experienced differently by different groups. Patient DRFC knowledge and self-care habits were typically suboptimal, and levels of hope and feeling of control over their condition varied between groups. Outcomes varied slightly between ethnicities across studies, with some ethnicity-specific themes identified such as beliefs about disease cause and footwear habits. Quantitative and qualitative findings were mostly congruent.

CONCLUSIONS

DRFC profoundly and negatively impacts patient-reported outcomes and experience, with limited evidence suggesting an influence of ethnicity.

Quality of life in older adults with chronic kidney disease and transient changes in renal function: Findings from the Oxford Renal cohort

Background

Quality of life (QoL) is an important measure of disease burden and general health perception. The relationship between early chronic kidney disease (CKD) and QoL remains poorly understood. The Oxford Renal Study (OxRen) cohort comprises 1063 adults aged ≥60 years from UK primary care practices screened for early CKD, grouped according to existing or screen-detected CKD diagnoses, or biochemistry results indicative of reduced renal function (referred to as transient estimated glomerular filtration rate (eGFR) reduction).

Objectives

This study aimed to compare QoL in participants known to have CKD at recruitment to those identified as having CKD through a screening programme.

Methods

Health profile data and multi-attribute utility scores were reported for two generic questionnaires: 5-level EuroQol-5 Dimension (EQ-5D-5L) and ICEpop CAPability measure for Adults (ICECAP-A). QoL was compared between patients with existing and screen-detected CKD; those with transient eGFR reduction served as the reference group in univariable and multivariable linear regression.

Results

Mean and standard deviation utility scores were not significantly different between the subgroups for EQ-5D-5L (screen-detected:0.785±0.156, n = 480, transient:0.779±0.157, n = 261, existing CKD:0.763±0.171, n = 322, p = 0.216) or ICECAP-A (screen-detected:0.909±0.094, transient:0.904±0.110, existing CKD:0.894±0.115, p = 0.200). Age, smoking status, and number of comorbidities were identified as independent predictors of QoL in this cohort.

Conclusion

QoL of participants with existing CKD diagnoses was not significantly different from those with screen-detected CKD or transient eGFR reduction and was similar to UK mean scores for the same age, suggesting that patient burden of early CKD is minor. Moreover, CKD-related comorbidities contribute more significantly to disease burden in earlier stages of CKD than renal function per se. Larger prospective studies are required to define the relationship between QoL and CKD progression more precisely. These data also confirm the essentially asymptomatic nature of CKD, implying that routine screening or case finding are required to diagnose it.

Factors affecting quality of life in patients with rheumatoid arthritis in South Korea: a cross-sectional study

INTRODUCTION

Rheumatoid arthritis (RA) is a chronic inflammatory disease that significantly reduces the quality of life (QOL) of affected patients. Many studies have emphasized the deterioration of QOL during the treatment of patients with RA, but factors that affect this phenomenon in Koreans with RA remain unclear.

METHODS

In this cross-sectional study, 166 Korean patients with RA were enrolled, and their general characteristics, disease-related characteristics, fatigue, feelings of depression, self-efficacy, social support, and QOL were assessed.

RESULTS

The overall mean score for RA-specific QOL was 5.8 out of 10. Fatigue, depression, self-efficacy, and social support were found to be significantly associated with the QOL of patients with RA. Notably, self-efficacy was found to be the most significant predictor of QOL.

CONCLUSIONS

Compared to patients with RA in Western countries, Korean patients with RA, even those with better physical function, seem to have a lower QOL. Identification of the relevant physical, psychological, and social factors affecting QOL in Koreans with RA is beneficial for clinical practice. Incorporation of strategies to address these factors, such as cognitive behavioral therapy, should be considered for the holistic management of RA. Key Points • Korean patients with RA report lower levels of QOL. • Factors associated with the QOL of patients with RA were fatigue, depression, self-efficacy, and social support. • Self-efficacy was the strongest factor affecting QOL in this population; thus, it would be beneficial for clinical practitioners to incorporate cognitive-behavioral approaches into patient education to enhance self-management. • Our findings suggest that QOL and psychological factors should also be regularly evaluated for the holistic management of patients with RA.

Protocolised non-invasive compared with invasive weaning from mechanical ventilation for adults in intensive care: the Breathe RCT

BACKGROUND

Invasive mechanical ventilation (IMV) is a life-saving intervention. Following resolution of the condition that necessitated IMV, a spontaneous breathing trial (SBT) is used to determine patient readiness for IMV discontinuation. In patients who fail one or more SBTs, there is uncertainty as to the optimum management strategy.

OBJECTIVE

To evaluate the clinical effectiveness and cost-effectiveness of using non-invasive ventilation (NIV) as an intermediate step in the protocolised weaning of patients from IMV.

DESIGN

Pragmatic, open-label, parallel-group randomised controlled trial, with cost-effectiveness analysis.

SETTING

A total of 51 critical care units across the UK.

PARTICIPANTS

Adult intensive care patients who had received IMV for at least 48 hours, who were categorised as ready to wean from ventilation, and who failed a SBT.

INTERVENTIONS

Control group (invasive weaning): patients continued to receive IMV with daily SBTs. A weaning protocol was used to wean pressure support based on the patient's condition. Intervention group (non-invasive weaning): patients were extubated to NIV. A weaning protocol was used to wean inspiratory positive airway pressure, based on the patient's condition.

MAIN OUTCOME MEASURES

The primary outcome measure was time to liberation from ventilation. Secondary outcome measures included mortality, duration of IMV, proportion of patients receiving antibiotics for a presumed respiratory infection and health-related quality of life.

RESULTS

A total of 364 patients (invasive weaning, n = 182; non-invasive weaning, n = 182) were randomised. Groups were well matched at baseline. There was no difference between the invasive weaning and non-invasive weaning groups in median time to liberation from ventilation {invasive weaning 108 hours [interquartile range (IQR) 57-351 hours] vs. non-invasive weaning 104.3 hours [IQR 34.5-297 hours]; hazard ratio 1.1, 95% confidence interval [CI] 0.89 to 1.39; p = 0.352}. There was also no difference in mortality between groups at any time point. Patients in the non-invasive weaning group had fewer IMV days [invasive weaning 4 days (IQR 2-11 days) vs. non-invasive weaning 1 day (IQR 0-7 days); adjusted mean difference -3.1 days, 95% CI -5.75 to -0.51 days]. In addition, fewer non-invasive weaning patients required antibiotics for a respiratory infection [odds ratio (OR) 0.60, 95% CI 0.41 to 1.00; p = 0.048]. A higher proportion of non-invasive weaning patients required reintubation than those in the invasive weaning group (OR 2.00, 95% CI 1.27 to 3.24). The within-trial economic evaluation showed that NIV was associated with a lower net cost and a higher net effect, and was dominant in health economic terms. The probability that NIV was cost-effective was estimated at 0.58 at a cost-effectiveness threshold of £20,000 per quality-adjusted life-year.

CONCLUSIONS

A protocolised non-invasive weaning strategy did not reduce time to liberation from ventilation. However, patients who underwent non-invasive weaning had fewer days requiring IMV and required fewer antibiotics for respiratory infections.

FUTURE WORK

In patients who fail a SBT, which factors predict an adverse outcome (reintubation, tracheostomy, death) if extubated and weaned using NIV?

Health-related quality of life among cervical cancer patients in India

INTRODUCTION

Estimation of health-related quality of life of cervical cancer patients in India is important in assessing the well-being of patients, monitor treatment outcomes, and conduct health technology assessments. However, health-related quality of life estimates for different stages of cervical cancer are not available for the Indian population. This study aims to generate stage-specific quality of life scores for cervical cancer patients in India.

METHODS

A cross-sectional study using the EQ-5D (EuroQol 5-dimensions) instrument, that consists of the EQ-5D-5L descriptive system and the EuroQol Visual Analog Scale (EQ-VAS) was conducted. A total of 159 cervical cancer patients were interviewed. Mean EQ-5D-5L quality of life scores (utility scores) were calculated using the EQ-5D-5L index value calculator across different stages of cervical cancer. The proportion of patients reporting problems in different attributes of EQ-5D-5L was assessed. The impact of socio-economic determinants on health-related quality of life was evaluated using multiple linear regression.

RESULTS

The mean EQ-5D-5L and EQ-VAS utility scores among patients of cervical cancer were 0.64 [95% CI=0.61-0.67] and 67.6 [95% CI=65.17-70.03], respectively. The most frequently reported problem among cervical cancer patients was pain/discomfort (61.88%), followed by difficulty in performing usual activities (53.81%), and anxiety/depression (41.26%).

CONCLUSION

Cervical cancer significantly impacts the health-related quality of life of the patients in India. Clinical interventions should focus on the control of pain and relief of anxiety. The measurement of health-related quality of life should be an integral component of the effectiveness of interventions as well as health technology assessment.

Health related outcomes among people with type 2 diabetes by country of birth: Result from the 45 and Up Study

BACKGROUND

Ethnic variation in the occurrence of type 2 diabetes, complications, mortality, and health behaviours has been reported. The current research examined patterns of health-related outcomes by country of birth in people with diabetes aged 45years and over in New South Wales, Australia.

METHODS

This study was based on the baseline data of 266,848 participants aged 45years and over from "The Sax Institute's 45 and Up Study" (2006-2009), NSW; Australia's most populous state. Health-related factors including self-rated overall health, Quality of Life (QoL), eyesight, subjective memory complaint, hearing loss, psychological distress and functional limitation were examined according to country of birth among 23,112 people with type 2 diabetes. Logistic regression modelling was used to compare the odds of poor outcomes between Australian-born and overseas-born participants, adjusting for potential confounding and mediating variables. Both age-sex and fully adjusted odds ratios (aORs) are reported.

RESULTS

Nearly half of the people with diabetes in the sample reported hearing loss and high levels of functional limitations, a third reported poor overall health. Compared to people with diabetes born in Australia, people born in South East Europe, North Africa, the Middle East had significantly greater odds of poor outcomes across the majority of examined health-related factors, with the largest odds observed in the elevated level of psychological distress outcome (aOR=3.4 in North African and the Middle East group). Higher aORs of poor overall health, QoL, memory problems and poor eyesight, and lower aORs for hearing loss, were also found among those born in the Asian countries.

CONCLUSIONS

The results demonstrated significant ethnic disparity in the prevalence of health-related outcomes. These findings provide important context for the formulation of culturally sensitive secondary prevention strategies.

Improving prevention, monitoring and management of diabetes among ethnic minorities: contextualizing the six G's approach

Objective

People from Black, Asian and Minority Ethnic (BAME) groups are known to have an increased risk of developing diabetes and face greater barriers to accessing healthcare resources compared to their ‘white British’ counterparts. The extent of these barriers varies by demographics and different socioeconomic circumstances that people find themselves in. The purpose of this paper is to present and discuss a new framework to understand, disentangle and tackle these barriers so that improvements in the effectiveness of diabetes interventions for BAME communities can be achieved.

Results

The main mediators of lifestyle behavioural change are gender, generation, geography, genes, God/religion, and gaps in knowledge and economic resources. Dietary and cultural practices of these individuals significantly vary according to gender, generation, geographical origin and religion. Recognition of these factors is essential in increasing knowledge of healthy eating, engagement in physical activity and utilisation of healthcare services. Use of the six G’s framework alongside a community centred approach is crucial in developing and implementing culturally sensitive interventions for diabetes prevention and management in BAME communities. This could improve their health outcomes and overall wellbeing.

Health utilities using SF-6D scores in Japanese patients with chronic hepatitis C treated with sofosbuvir-based regimens in clinical trials

Background

Health utilities are preference-based measures for health states which are typically used in economic analyses to estimate quality-adjusted life years. Our aim is to report the standard SF-6D health utility scores in Japanese patients with hepatitis C virus (HCV) during treatment with different regimens.

Methods

Japanese patients were enrolled in clinical trials of sofosbuvir (SOF) used in combination with or without ledipasvir (LDV) and/or ribavirin (RBV). The SF-6D health utility scores were calculated at multiple time points from the SF-36 instrument.

Results

Four hundred ninety-four patients with HCV (genotype 1 and 2) were enrolled: 19% with cirrhosis, 48% with a prior history of anti-HCV treatment. Of those, 153 received SOF + RBV, 170 received LDV/SOF + RBV, 171 received LDV/SOF for 12 weeks; the SVR rates were: 97, 98 and 100%, respectively. Patients treated with the three regimens had similar SF-6D scores before treatment (p = 0.87): 76.1 ± 11.5. During treatment with RBV containing regimen, patients experienced a decrement in their health utility scores to 74.3 ± 12.5 by the end of treatment (p = 0.03), while patients treated with RBV-free LDV/SOF had their SF-6D scores improved to 79.2 ± 12.8 after 12 weeks of treatment (p = 0.0004). At post-treatment week 12, in patients who achieved SVR-12, the SF-6D scores were similar between the treatment regimens (p = 0.36), and an average improvement of +1.4 points from baseline (p = 0.01) was noted. In multivariate analysis, the use of RBV was independently associated with lower utility score during treatment (beta = 4.7 ± 1.6, p < 0.0001).

Conclusion

Health utilities are lower in Japanese HCV patients and tend to improve after clearance of infection.

Prevalence and correlates of psychological distress among diabetes mellitus adults in the Jilin province in China: a cross-sectional study

BACKGROUND

Psychological disorders are common in diabetes mellitus (DM) patients, and the aim of this study was to estimate the prevalence of psychological distress and to determine the influence factors associated with psychological distress among DM patients in the Jilin province of China.

METHODS AND MATERIALS

Multistage, stratified cluster sampling was used in this cross-sectional study. The 12-item General Health Questionnaire (GHQ-12) was used to assess psychological status with the total score of ≥4 as the threshold for psychological distress.

RESULTS

A total of 1,956 subjects with DM were included in the study. Out of this total diabetic participants, 524 (26.8%) had psychological distress. Multiple logistic regression analysis showed that low educational level, divorce or separation from one's spouse, low family average monthly income, short sleep duration, being aware of DM status, and multiple co-morbidities are positively associated with psychological distress (all P < 0.05).

CONCLUSIONS

This study revealed a high rate of psychological distress among DM population in Jilin province. Low educational level, divorce or separation from one's spouse, low family average monthly income, short sleep duration, awareness of DM status, and multiple co-morbidities are all associated with psychological distress among our study subjects. Interventions to control these factors are needed to address the psychological problems among diabetics in Jilin Province.

Relationship between amputation and risk factors in individuals with diabetes mellitus: A study with Brazilian patients

Individuals with diabetes develop lower extremity amputation for several reasons. Investigations into pathways to the development of complications are important both for treatment and prevention.

AIM

To evaluate the relationship between amputation and risk factors in people with diabetes mellitus.

MATERIALS AND METHOD

All participants included in this study (n=165) were recruited from the Diabetic Foot Program, developed in a Brazilian University, over seven years (2007-2014) and all information for this study was extracted from their clinical records.

RESULTS

The prevalence of amputation in patients with diabetes with four risk factors was up to 20% higher when compared to those with only one risk factor. The main predictive risk factors for amputation in this population were the presence of an ulcer and smoking.

CONCLUSION

The risk factors for amputation can be predicted for people with diabetes mellitus and, in the present study, the main factors were the presence of an ulcer and the smoking habit.

The impact of type 2 diabetes on health related quality of life in Bangladesh: results from a matched study comparing treated cases with non-diabetic controls

BACKGROUND

Little is known about the association between diabetes and health related quality of life (HRQL) in lower-middle income countries. This study aimed to investigate HRQL among individuals with and without diabetes in Bangladesh.

METHODS

The analysis is based on data of a case-control study, including 591 patients with type 2 diabetes (cases) who attended an outpatient unit of a hospital in Dhaka and 591 age -and sex-matched individuals without diabetes (controls). Information about socio-demographic characteristics, health conditions, and HRQL were assessed in a structured interview. HRQL was measured with the EuroQol (EQ) visual analogue scale (VAS) and the EQ five-dimensional (5D) descriptive system. The association between diabetes status and quality of life was examined using multiple linear and logistic regression models.

RESULTS

Mean EQ-VAS score of patients with diabetes was 11.5 points lower (95 %-CI: -13.5, -9.6) compared to controls without diabetes. Patients with diabetes were more likely to report problems in all EQ-5D dimensions than controls, with the largest effect observed in the dimensions 'self-care' (OR = 5.9; 95 %-CI: 2.9, 11.8) and 'mobility' (OR = 4.5; 95 %-CI: 3.0, -6.6). In patients with diabetes, male gender, high education, and high-income were associated with higher VAS score and diabetes duration and foot ulcer associated with lower VAS scores. Other diabetes-related complications were not significantly associated with HRQL.

CONCLUSIONS

Our findings suggest that the impact of diabetes on HRQL in the Bangladeshi population is much higher than what is known from western populations and that unlike in western populations comorbidities/complications are not the driving factor for this effect.

Evaluation of Health-Related Quality of Life among Patients with Cervical Cancer in Indonesia

BACKGROUND

Evaluation of health-related quality of life (HRQOL) in cervical cancer patients is important in order to design the interventions for improving patient outcomes. Reports of HRQOL among cervical cancer patients in Indonesia are limited. Moreover, measurement using EQ-5D-3L is to our best knowledge has hitherto not been performed. This study aimed to examine the HRQOL of cervical cancer patients in Indonesia using EQ- 5D-3L.

MATERIALS AND METHODS

A cross-sectional study was conducted by interviewing cervical cancer patients using the EQ-5D-3L questionnaire. Percentages of patients who reported having problems in each dimension of EQ-5D as well as EQ-5D index score (utility) were calculated.

RESULTS

Our findings indicated that the most frequent reported problems were pain/discomfort (67.8%) followed by anxiety/depression (57.5%). The mean of EQ-5D VAS was 75.8 (SD=17.0). The mean (SD) utility scores were 0.85 (0.19), 0.76 (0.20), 0.71 (0.21), and 0.77 (0.13) for cervical cancer patients in stage I, II, III, and IV, respectively.

CONCLUSIONS

Cervical cancer significantly affects patient HRQOL. Efforts should be made to improve the quality of life of cervical cancer patients especially in terms of pain /discomfort and anxiety/depression reduction.

Depressive Symptoms, Family Functioning and Quality of Life in Chinese Patients with Type 2 Diabetes

OBJECTIVE

Patients with type 2 diabetes mellitus often have depression or depressive symptoms, impaired family functioning and poor quality of life. This study aimed to examine relationships among psychological variables, including depressive symptoms, family functioning and quality of life, for Chinese patients with type 2 diabetes and to explore the influencing factors on quality of life for these patients.

METHOD

In this cross-sectional study, 257 patients with type 2 diabetes and 259 nondiabetic community controls completed the Beck Depression Inventory, the Family Assessment Device, and the Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form.

RESULTS

Patients with type 2 diabetes reported significant family impairment in the dimension of affective involvement compared with nondiabetic community controls (p<0.05). Mean Family Assessment Device scores were negatively associated with quality of life scores among patients with type 2 diabetes. Age, depressive symptoms, duration of diabetes, communication, affective involvement and behavioural control were associated with quality of life in patients with type 2 diabetes.

CONCLUSIONS

The results indicate that having type 2 diabetes was associated with some difficulties with family functioning and that poor family functioning was associated with a poorer quality of life. Additional factors, including older age, depressive symptoms, duration of diabetes, and some dimensions of family functioning, were found to be associated with quality of life in Chinese individuals with type 2 diabetes.

Relationship of treatment satisfaction to health-related quality of life among Palestinian patients with type 2 diabetes mellitus: Findings from a cross-sectional study

OBJECTIVES

The aims of the current study were to assess the association between health-related quality of life (HRQoL) and treatment satisfaction in a sample of diabetic patients from Palestine, and to determine the influence of socio-demographic and clinical factors on HRQoL.

METHODS

It was a cross-sectional study performed during the period June 2013 to October 2013. The Arabic version of Treatment Satisfaction Questionnaire for Medication (TSQM 1.4) was used to assess treatment satisfaction, and the Arabic version of European Quality of Life scale (EQ-5D-5L) was used to assess HRQoL. Multiple linear regression was used to estimate which variables were the most important related to HRQoL.

RESULTS

A total of 385 diabetic patients were included. There were modest positive correlations between the total score on the Overall Satisfaction domain and EQ-5D-5L (r = 0.14; p = 0.005). After adjusting multiple covariates by multiple linear regression, the association between the Overall Satisfaction and HRQoL was not statistically significant (p = 0.075); (R = 0.495; adjusted R² = 0.245; F = 10.3; df = 12; p < 0.001). The results showed that elderly patients, being unemployed, and number of comorbid diseases, were significantly associated with HRQoL.

CONCLUSIONS

Overall, these results indicate that elderly patients, being unemployed, and those with comorbid diseases, are independent risk factors for poor HRQoL. Furthermore, it emerges that HRQoL and treatment satisfaction are both probably influenced by socio-demographic and clinical characteristics. In fact, to improve diabetic patients' quality of life, elderly patients were recommended to receive more attention in their health and economic status.
