Quality of life in relation to social and disease factors in patients with type 2 diabetes in Lithuania

Insulin therapy in type 2 diabetes: Insights into clinical efficacy, patient-reported outcomes, and adherence challenges

Insulin therapy plays a crucial role in the management of type 2 diabetes as the disease progresses. Over the past century, insulin formulations have undergone significant modifications and bioengineering, resulting in a diverse range of available insulin products. These products show distinct pharmacokinetic and pharmacodynamic profiles. Consequently, various insulin regimens have em-erged for the management of type 2 diabetes, including premixed formulations and combinations of basal and bolus insulins. The utilization of different insulin regimens yields disparate clinical outcomes, adverse events, and, notably, patient-reported outcomes (PROs). PROs provide valuable insights from the patient's perspective, serving as a valuable mine of information for enhancing healthcare and informing clinical decisions. Adherence to insulin therapy, a critical patient-reported outcome, significantly affects clinical outcomes and is influenced by multiple factors. This review provides insights into the clinical effectiveness of various insulin preparations, PROs, and factors impacting insulin therapy adherence, with the aim of enhancing healthcare practices and informing clinical decisions for individuals with type 2 diabetes.

Health-Related Quality of Life Among Type 2 Diabetes Mellitus Patients Using the 36-Item Short Form Health Survey (SF-36) in Central Ethiopia: A Multicenter Study

Introduction

Diabetes, one of the major global health emergencies of the 21st century, can affect a patient's quality of life. A compromised quality of life has adverse effects on self-care practices, resulting in inadequate glycemic control and an increased susceptibility to complications. In Ethiopia, there is a paucity of information regarding the quality of life of patients with type 2 diabetes mellitus. Therefore, this study aimed to assess health-related quality of life in type 2 diabetes mellitus patients.

Methods

A cross-sectional study was conducted among type 2 diabetes mellitus patients attending diabetes follow-up clinics in selected public hospitals in Addis Ababa using short form- 36 (SF-36) health survey measures. Descriptive statistics were used to summarize the characteristics of the study participants. Simple and multiple linear regressions were done to identify significantly associated factors with health-related quality of life.

Result

A total of 309 patients participated in this study. The mean scores of the physical and mental component summaries were 40.15 (SD = 7.27) and 48.11 (SD = 8.87), respectively. Being old, being overweight or obese, living with type 2 diabetes mellitus for more than fifteen years, taking combined medication, having diabetes-related complications, and having comorbidities were factors that reduced the mean score of the physical component summary (p-value<0.05). Being obese and diabetes related complication were factors that negatively affect mental component summary (p-value <0.05). On the other hand, being married was factors that positively affect mental component summary (p-value <0.05).

Conclusion

Older age, being married, obesity, overweight, longer duration of diabetes, using combined medications, diabetic-related complications, and co-morbidities were factors associated with health-related quality of life. Healthcare providers should strengthen counseling patients on lifestyle modifications such as diet modifications, and weight reduction.

Quality of life and mental health measurements among patients with type 2 diabetes mellitus: a systematic review

BACKGROUND

Over the past few decades the benefits of assessing Quality of Life (QoL) and mental health in patients with Type 2 Diabetes Mellitus (T2DM) have steadily increased with limited studies relating to the most useful method to assess these patients. This study aims to identify, review, summarise, and evaluate the methodological quality for the most validated commonly used health-related QoL and mental health assessment measurements in diabetic patients.

METHODS

All original articles published on PubMed, MedLine, OVID, The Cochrane Register, Web of Science Conference Proceedings and Scopus databases were systematically reviewed between 2011 and 2022. A search strategy was developed for each database using all possible combinations of the following keywords: "type 2 diabetes mellitus", "quality of life", mental health", and "questionnaires". Studies conducted on patients with T2DM of ≥ 18 years with or without other clinical illnesses were included. Articles designed as a literature or systematic review conducted on either children or adolescents, healthy adults and/or with a small sample size were excluded.

RESULTS

A total of 489 articles were identified in all of the electronic medical databases. Of these articles, 40 were shown to meet our eligibility criteria to be included in this systematic review. Approximately, 60% of these studies were cross-sectional, 22.5% were clinical trials, and 17.5% of cohort studies. The top commonly used QoL measurements are the SF-12 identified in 19 studies, the SF-36, included in 16 studies, and the EuroQoL EQ-5D, found in 8 studies. Fifteen (37.5%) studies used only one questionnaire, while the remaining reviewed (62.5%) used more than one questionnaire. Finally, the majority (90%) of studies reported using self-administered questionnaires and only 4 used interviewer mode of administration.

CONCLUSION

Our evidence highlights that the commonly used questionnaire to evaluate the QoL and mental health is the SF-12 followed by SF-36. Both of these questionnaires are validated, reliable and supported in different languages. Moreover, using single or combined questionnaires as well as the mode of administration depends on the clinical research question and aim of the study.

Health-related quality of life in patients with type 2 diabetes initiating a second-line glucose-lowering therapy: The DISCOVER study

AIM

To investigate factors associated with health-related quality of life (HRQoL) in patients with type 2 diabetes mellitus (T2D) at initiation of second-line glucose-lowering therapy.

METHODS

DISCOVER is a 3-year, prospective observational study of patients with T2D initiating second-line glucose-lowering therapy, conducted in 38 countries. HRQoL at baseline was assessed using the physical and mental component summary (PCS; MCS) scores of the 36-Item Short Form Health Survey version 2 (SF-36v2) in 31 countries (n = 8309) and the Hypoglycaemia Fear Survey-II (HFS-II) in 23 countries (n = 6516). Factors associated with differences in HRQoL were assessed using multivariable hierarchical regression models.

RESULTS

Mean PCS and MCS scores were 48.0 (standard deviation [SD]: 7.8) and 45.5 (SD: 10.4), respectively. Factors associated with significantly lower SF-36v2 scores included being female, having a history of macrovascular complications and first-line treatment with oral combinations (vs metformin monotherapy). Mean HFS-II behaviour and worry scores were 8.2 (SD: 9.9) and 7.3 (SD: 11.8), respectively. Increased fear of hypoglycaemia was significantly associated with lower SF-36v2 scores.

CONCLUSIONS

Several patient-, disease- and treatment-related characteristics correlated with HRQoL, indicating that a multifactorial approach is needed to maintain HRQoL in patients with T2D.

High-level of anxiety and depressive symptoms among patients with general medical conditions and community residents: a comparative study

BACKGROUND

The global burden of anxiety and depressive symptoms become increasing, specifically accounts for high burden of morbidity among patients with medical conditions in low-income countries. The aim was to compare the level of anxiety and depressive symptoms in participants with general medical conditions and community residents in northwest Ethiopia.

METHODS

Comparatively 2625 adults in the community and 1363 patients at health center in Mecha Demographic Surveillance and Field Research Center (MDSFRC) had interviewed. Level of anxiety and depressive symptoms was assessed by Hospital Anxiety and Depression Scale (HADS) and logistic regression analysis was employed with corresponding adjusted OR (AOR) and 95% confidence interval (CI) at p-value less than 0.05 declaration of significant.

RESULTS

A higher prevalence of high-level anxiety and depressive symptoms, 12.6% with 95% CI; 11.0%, 14.0% and 10.1%, 95% CI; 8.0%, 12% were found among participants at health center compared to community residents, 6.8%, 95% CI; 7.0%, 8.0% and 5.2%, 95% CI; 4.0%, 6.0% at (p value < .0001), respectively. Social support, loss of a parent before age of 18 years, physical/verbal abuse, and having general medical conditions were significantly associated with both high-level anxiety and depressive symptoms. However, factors such as advanced age, perceived relative wealth, living alone, and having a family history of mental illness were associated with high-level of anxiety symptoms, but not with depressive symptoms.

CONCLUSIONS

Proportion of high-level of anxiety and depressive symptoms were found a two-fold higher in patients with medical condition than healthy residents in the community. Patients with medical illnesses should be assess for anxiety and depressive symptoms at health center.

Quality of life among adult patients living with diabetes in Rwanda: a cross-sectional study in outpatient clinics

OBJECTIVES

To report on the disease-related quality of life of patients living with diabetes mellitus in Rwanda and identify its predictors.

DESIGN

Cross-sectional study, part of the baseline assessment of a cluster-randomised controlled trial.

SETTING

Outpatient clinics for non-communicable diseases of nine hospitals across Rwanda.

PARTICIPANTS

Between January and August 2019, 206 patients were recruited as part of the clinical trial. Eligible participants were those aged 21-80 years and with a diagnosis of diabetes mellitus for at least 6 months. Illiterate patients, those with severe hearing or visual impairments, those with severe mental health conditions, terminally ill, and those pregnant or in the postpartum period were excluded PRIMARY AND SECONDARY OUTCOME MEASURES: Disease-specific quality of life was measured with the Kinyarwanda version of the Diabetes-39 (D-39) questionnaire. A glycated haemoglobin (HbA1c) test was performed on all patients. Sociodemographic and clinical data were collected, including medical history, disease-related complications and comorbidities.

RESULTS

The worst affected dimensions of the D-39 were 'anxiety and worry' (mean=51.63, SD=25.51), 'sexual functioning' (mean=44.58, SD=37.02), and 'energy and mobility' (mean=42.71, SD=20.69). Duration of the disease and HbA1c values were not correlated with any of the D-39 dimensions. A moderating effect was identified between use of insulin and achieving a target HbA1c of 7% in the 'diabetes control' scale. The most frequent comorbidity was hypertension (49.0% of participants), which had a greater negative effect on the 'diabetes control' and 'social burden' scales in women. Higher education was a predictor of less impact on the 'social burden' and 'energy and mobility' scales.

CONCLUSIONS

Several variables were identified as predictors for the five dimensions of quality of life that were studied, providing opportunities for tailored preventive programmes. Further prospective studies are needed to determine causal relationships.

Factors Associated With Health-Related Quality of Life in Patients With Diabetic Foot Ulcer: A Cross-Sectional Study From Saudi Arabia

Background and objective Diabetic foot ulcers (DFU) have been shown to have a high impact on the patients' perceived health-related quality of life (HRQOL). The aim of this study was to estimate the HRQOL and its related risk factors in patients with foot ulcers associated with type 2 diabetes mellitus (T2DM). Methods This cross-sectional study was performed on 81 patients with DFU, from January 2019 to July 2019 at the Prince Sultan Military Medical City (PSMMC), Riyadh, Saudi Arabia. The study population was purposively and conveniently chosen based on patients' availability during their regular and customary outpatient clinic visits. Using the Arabic version of the Short-Form 36-Item Survey (SF-36), these patients were interviewed and their HRQOL scores were was assessed. The SF-36 covered eight aspects of health such as physical functioning, body pain, limitations in the roles induced by physical health problems, limitations in the roles caused by personal or emotional problems, emotional well-being, social functioning, energy/fatigue, and general health perceptions. Results It was evident that age, gender, education, occupation, smoking, duration of diabetes, hypertension, dyslipidemia, body mass index (BMI), and the number of diabetes-associated complications, hypertension, and dyslipidemia significantly affected the patients' physical functions. The physical health of the patient was strongly influenced by gender, education, occupation, income, BMI, and the number of complications. The emotional health of the patient was affected by dyslipidemia, deformity, prior amputations, as well as BMI and glycosylated hemoglobin (HbA1c). The social standing of the patient was influenced by age, income, education, and occupation. The degree of pain experienced by the patient varied with age and the number of complications, as well as notable differences in their general health. The factors of age, education, occupation, income, and the number of diabetic complications induced several health changes in varying degrees. The patients with DFU revealed overall lower HRQOL relating to all the eight aspects of the SF-36. Conclusion The patients with DFU in Saudi Arabia generally revealed lower HRQOL. However, prospective and large-scale studies are required in the future to support these findings.

Demographic and clinical predictors of health-related quality of life among people with type 2 diabetes mellitus living in northern Thailand: A cross-sectional study

Background

Type 2 Diabetes Mellitus (T2DM) is a chronic disease which is growing global health problems. However, research on such prediction of health-related quality of life (HRQOL) in Thailand is limited, in particular on the demographic and clinical characteristic in each HRQOL domains. Therefore, the aim of the present study was to determine the demographic and clinical predictors of health-related quality of life among people with type 2 diabetes mellitus (T2DM) in Northern Thailand.

Methods

A cross-sectional study of people with T2DM at a large teaching hospital in Northern Thailand was conducted. The HRQOL was evaluated using the Thai version of Diabetes-39. Descriptive analysis was used to summarize the demographic and HRQOL scores. Multiple regression analysis was used to determine the predictors of overall HRQOL and the predictors of each D-39 dimension.

Results

A total of 502 people with T2DM were recruited. Forty-one were identified as having diabetic foot ulcers. The mean score for perception of overall HRQOL was 61.18 (SD 18.74). Scores in the D-39 questionnaire showed a poor HRQOL among people with T2DM. The predictors of demographic and clinical characteristics of people with T2DM were calculated for overall HRQOL and all six domains.

Conclusion

These results demonstrate that people with T2DM have a poor HRQOL. The presence of diabetic foot ulcers and smoking status were identified as significant predictors of low HRQOL in the domains relating to diabetes control, social burden and energy and mobility presence of obesity, receiving insulin injection or a combination of insulin and oral medication were predictors of poor HRQOL in the domain of other health problems and diabetes complications. These findings allow for a nursing care plan for diabetes management to achieve optimal glycaemic control and improve their HRQOL.

Modeling the factors affecting the quality of life in diabetic patients in India using total interpretive structural modeling

Purpose

Diabetes mellitus has become a major world health problem that has unenviable impacts on health of the people including quality of life (QOL) also and in which person’s physical and psychological state, social commitments and relationships and his interaction with the environment is affected. This shows that there is an urgent need for behavior change and considerable educational strategies for proper management and rehabilitation (Reddy, 2000). This research has identified and ranked the significant factors which affect the QOL in diabetic patients in India. The paper aims to discuss these issues.

Design/methodology/approach

In this paper, nine factors which affect the QOL in diabetic patients in India have been identified through review of the literature and evaluated by total interpretive structural modeling (TISM) approach, i.e. an extended version of ISM. In this approach, interpretations of the interrelationship among factors have been discussed. Therefore, TISM approach has been used to develop the model and the mutual interactions among these factors.

Findings

The results of the model and MICMAC analysis indicate that diet restriction, body pain and satisfaction with treatment are the top-level factors.

Practical implications

Identification of the factors that have a remarkable effect on the QOL in diabetic patients is very important so that the doctors and other healthcare professionals may handle these factors efficiently and proper rehabilitation can be provided to such patients.

Originality/value

This paper has used an application of the TISM approach to interpret the mutual relationship by using the tool of interpretive matrix and has developed a framework to calculate the drive and the dependence power of factors using MICMAC analysis. The issues related to QOL are extremely important, as they can strongly anticipate a person’s capability to govern his lifestyle with disease like diabetes mellitus and maintain good health in the long run. This shows the urgent requirement of an optimized model which can predict and interpret the relationships among these factors. In this research, the interrelationships among these factors have been developed and interpretations of these interactions have been given to develop a comprehensive model so that QOL of diabetic patients may be improved.

The association between insulin therapy and depression in patients with type 2 diabetes mellitus: a meta-analysis

OBJECTIVES

Several patients with type 2 diabetes mellitus (T2DM) have depressive disorders. Whether insulin treatment was associated with increased risk of depression remains controversial. We performed a meta-analysis to evaluate the association of insulin therapy and depression.

DESIGN

A meta-analysis.

METHODS

We conducted a systematic search of PubMed, PsycINFO, Embase and the Cochrane Library from their inception to April 2016. Epidemiological studies comparing the prevalence of depression between insulin users and non-insulin users were included. A random-effects model was used for meta-analysis. The adjusted and crude data were analysed.

RESULTS

Twenty-eight studies were included. Of these, 12 studies presented with adjusted ORs. Insulin therapy was significantly associated with increased risk of depression (OR=1.41, 95% CI 1.13 to 1.76, p=0.003). Twenty-four studies provided crude data. Insulin therapy was also associated with an odds for developing depression (OR=1.59, 95% CI 1.41 to 1.80, p<0.001). When comparing insulin therapy with oral antidiabetic drugs, significant association was observed for adjusted (OR=1.42, 95% CI 1.08 to 1.86, p=0.008) and crude (OR=1.61, 95% CI 1.35 to 1.93, p<0.001) data.

CONCLUSIONS

Our meta-analysis confirmed that patients on insulin therapy were significantly associated with the risk of depressive symptoms.

Validation of the LITHUANIAN version of the 19-item audit of diabetes dependent quality of life (ADDQOL - LT) questionnaire in patients with diabetes

BACKGROUND

Currently there is no diabetes-specific quality of life (QOL) instrument available in Lithuanian language. We aimed to develop a Lithuanian version of a widely-used individualised instrument - the Audit of Diabetes Dependent Quality of Life questionnaire (ADDQOL-19) and assess the validity and reliability in patients with type 1 and type 2 diabetes mellitus (DM).

METHODS

This study was conducted at the Primary Care and Endocrinology Outpatient Clinics in Vilnius. The ADDQOL was translated from the original English (UK) into Lithuanian using a standardized methodology of forward and back translation. After cognitive "debriefing" the validity and reliability of LT-ADDQOL questionnaire were assessed in a sample of 138 diabetes patients. Cronbach's alpha coefficient, factor analysis, independent t tests and ANOVA were used.

RESULTS

There were 106 participants with type 2 and 32 with type 1 DM included in the study with a mean age of 55.5 years (± 14.5) and 56.2% women. The Cronbach's alpha coefficient was 0.908 and most of items loading values onto one single factor were larger than 0.40 (varied from 0.41 to 0.77), indicating good internal consistency and reliability of instrument.

CONCLUSIONS

We developed the Lithuanian version of ADDQOL-19 which is a valid and reliable instrument to measure impact of diabetes on QOL. It could be further used by clinicians and researchers for comprehensive assessment of QOL in adults with diabetes.

Related factors of quality of life of type 2 diabetes patients: a systematic review and meta-analysis

BACKGROUND

Diabetes is a chronic disease, and it could affect both health and quality of life (QOL). A lot of studies have reported some predictors of QOL of type 2 diabetes patients. While their results were not completely consistent. So the aim of our study was finding out the related factors (including characteristics related to the disease, life styles and mental health factors) of QOL of type 2 diabetes patients.

METHODS

We searched Cochrane library, EmBase, PubMed and CNKI databases for published studies that evaluated the related factors of QOL of type 2 diabetes patients by using a proper statistic method and had effect sizes (OR or β) and 95% confidence intervals from January 1st 2000 to May 31st 2016. Any study types were acceptable, and we excluded the reviews, letters, editorials and pooled analyses. The data were analyzed using STATA software (Version 12.0; Stata Corporation). Effect sizes and 95% confidence intervals were calculated to evaluate the relationship between these factors and QOL.

RESULTS

Eighteen studies were included into our systematic review and meta-analysis, totaling 57,109 type 2 diabetes patients. Do more physical exercises (The pooled ORs ranged from 0.635 to 0.825 for different scales, less than 1.00), glucose check more frequently [pooled OR (95%CI): 0.175 (0.041, 0.756)] were associated with a better QOL. Presence of complications (The pooled ORs ranged from 1.462 to 3.038 for different scales, more than 1.00), presence of hypertension [pooled OR (95%CI): 1.389 (1.173, 1644)], longer duration of diabetes [pooled OR (95%CI): 1.865 (1.088, 3.197)], diet with more red meat [pooled OR (95%CI): 2.085 (1.063, 4.089)] and depression (The pooled ORs ranged from 3.003 to 11.473 for different scales, higher than 1.00) were associated with a worse QOL.

CONCLUSION

The results of this study show that physical exercise, glucose check frequently, complications, hypertension, duration of diabetes, diet with more red meat, and depression were associated with the QOL of type 2 diabetes patients.

Glycemic control rate of T2DM outpatients in China: a multi-center survey

Background

Type 2 diabetes mellitus (T2DM)-associated mortality and morbidity are strongly dependent on glycemic control. With T2DM prevalence increasing in China, we aimed to assess glycemic control rates in Chinese T2DM outpatients.

Material/Methods

A total of 9065 adult T2DM outpatients (5035 men) were assessed in 26 Chinese medical centers between August 2010 and April 2012. Patients were stratified according to BMI (kg/m²): <24, 24–28, and >28. Successful glycemic control was defined as glycated hemoglobin A1c (HbA1c) ≤7% or fasting plasma glucose (FPG) <7.0 mmol/L.

Results

Among the participants included in this study, 2939 had BMI <24, 3361 had BMI of 24–28, and 2764 had BMI >28. The glycemic control rate was only 32.6%, and the triple control rate for glycemia, blood pressure, and lipidemia was only 11.2%. Glycemic control rates by BMI group were 33.7% (<24), 33.8% (24–28), and 30.2% (>28) (p=0.005), and corresponding incidences of cardiovascular diseases (CVD) were 12.2%, 15.7%, and 15.9% (p<0.001). Multivariate logistic regression analysis demonstrated that older age (p<0.001), higher BMI (p=0.026), larger waist circumference (p<0.001), less education (p<0.001), and recent diagnosis (p<0.001) were independent risk factors for poor glycemic control.

Conclusions

The T2DM glycemic control rate in China is currently low, especially in older obese patients with poor education and recent diagnosis.

Factors Associated with Health-Related Quality of Life among Saudi Patients with Type 2 Diabetes Mellitus: A Cross-Sectional Survey

BACKGROUND

Diabetes mellitus (DM) is associated with high mortality, morbidity, poor general health, and loss of health-related quality of life (HRQOL). The objective of the study was to assess the factors associated with HRQOL among patients with type 2 diabetes mellitus (T2DM).

METHODS

This was a cross sectional study conducted among 283 T2DM patients during June 2011 and September 2012 at a major tertiary hospital in Riyadh, Saudi Arabia. The respondents were purposively and conveniently selected according to their availability during their routine visit to the outpatient clinics and they were interviewed using the Arabic version of the Short-Form 36-item survey (SF-36) to assess the HRQOL.

RESULTS

The mean age of the participants was 56.4±13.2 years. Around 63% (178) were males and 37% (105) were females. Glycosylated hemoglobin level was found to be significantly higher among female and HRQOL was higher among male. Respondents who were more than 50 years old had poor HRQOL than less than 50 years age group. Poor economic status, reported diabetic complications and longer duration of diabetes were significantly associated with poor HRQOL. The respondents treated with combination of therapies (oral medication plus insulin) indicated better HRQOL than patients with insulin therapy alone. Multivariate analysis indicated that gender, economic status (except subscale energy), and complications of DM (except subscale energy) as independent risk factor for HRQOL.

CONCLUSION

Gender, economic status, and complication of DM were independent risk factors for majority of the subscales of HRQOL.

Prevalence and determinants of anxiety and depression symptoms in patients with type 2 diabetes in Lithuania

Background

Depression is associated with a variety of diabetes complications, including diabetic retinopathy, nephropathy, neuropathy, and macrovascular complications. The prevalence of the symptoms of anxiety (32%) and depression (22.4%) in patients with diabetes is considerably higher than in general population samples (10%). The aim of this study was to evaluate the prevalence and determinants of anxiety and depression symptoms in patients with type 2 diabetes (T2DM).

Material/Methods

This survey was conducted during 2007–2010. In total, 1500 patients were invited to participate in the study. The Hospital Anxiety and Depression Scale (HADS) was used to measure depression and anxiety for the evaluation of the depressive state and anxiety. Statistical analysis was carried out using SPSS 17.0.

Results

More than 70% of all respondents who participated in the study had diabetes mellitus complications (72.2%). The prevalence of mild to severe depression score was 28.5% (95% CI 25.7–31.4). The prevalence of anxiety was 42.4% (95% CI 39.3–45.5). Anxiety was more frequent among females (46.8%) than among males (34.7%) (p<0.001). A significant negative trend was observed between prevalence of anxiety and depression, and age and education (p for trend <0.001).

Conclusions

A significant association between depression and diabetic complications was identified (p<0.05). Duration of diabetes was a risk factor significantly associated with higher scores of anxiety among the patients with T2DM.

Multivitamin mineral supplementation in patients with chronic fatigue syndrome

Background

Chronic fatigue syndrome (CFS) is characterized by medically unexplained persistent or reoccurring fatigue lasting at least 6 months. CFS has a multifactorial pathogenesis in which oxidative stress (OS) plays a prominent role. Treatment is with a vitamin and mineral supplement, but this therapeutic option so far has not been properly researched.

Material/Methods

This prospective study included 38 women of reproductive age consecutively diagnosed by CDC definition of CFS and treated with a multivitamin mineral supplement. Before and after the 2-month supplementation, SOD activity was determined and patients self-assessed their improvement in 2 questionnaires: the Fibro Fatigue Scale (FFS) and the Quality of Life Scale (SF36).

Results

There was a significant improvement in SOD activity levels; and significant decreases in fatigue (p=0.0009), sleep disorders (p=0.008), autonomic nervous system symptoms (p=0.018), frequency and intensity of headaches (p=0.0001), and subjective feeling of infection (p=0.0002). No positive effect on quality of life was found.

Conclusions

Treatment with a vitamin and mineral supplement could be a safe and easy way to improve symptoms and quality of life in patients with CFS.

The cost of type 2 diabetes in Brazil: evaluation of a diabetes care center in the city of São Paulo, Brazil

BACKGROUND

The worldwide increase of diabetes, a long duration, slow progression disease, impacts health care costs. The aim of this study was to estimate, from the society's perspective, the annual cost per patient with Type 2 Diabetes (T2DM) at a specialized, outpatient center in the city of São Paulo, capital of São Paulo state, Brazil.

METHODS

Data from 209 patients were collected during the years 2009 and 2010 in a São Paulo diabetes care center which is part of the tertiary sector of SUS, Brazil's National Health Care System. Data were collected by means of interviews and reviews of medical charts, and the quality of life was appraised using the SF36-v2 questionnaire. Direct medical costs were divided in five categories: 1) medication; 2) laboratory tests; 3) hospitalizations and procedures; 4) reactive strips for capillary blood glucose monitoring; and 5) medical consultations. Direct non-medical costs referred to transportation of patient and companion for treatment. Indirect costs included early retirements, sick leave and absenteeism in the workplace. Statistical analysis of the data was performed by the SPSS software, version 17.0.

RESULTS

Our sample comprised 122 women (58%) and 87 men (42%), with mean age of 63 years and average diabetes duration of 13 years. The mean annual cost was US$ 1,844 per patient, out of which US$ 1,012 corresponded to direct costs (55%) and US$ 831 to indirect costs (45%). From the direct medical costs, medications accounted for the greatest proportion (42%), followed by reactive strips (27%), hospitalizations and procedures (14%), laboratory tests and image examinations (7%), as well as medical consultations (4%). Non-medical costs (transportation) corresponded to 7% of the total direct costs. Besides, the results indicated that men have better quality of life than women.

CONCLUSION

This study demonstrated a high T2DM cost in Brazil, considering the governmental per capita expenses in health care, which accounted for US$ 466 in 2010 (World Health Statistics 2013 96-104 2013). Taking into account the high prevalence of the disease (IDF Diabetes Atlas. 5th edition. 29-48 2012), this survey recommends the enforcement of policies for the prevention of diabetes and its complications, and urges for better allocation of healthcare resources.
