Predictions Burden of Diabetes and Economics Cost: Contributing Risk Factors of Changing Disease Prevalence and its Pandemic Impact to Qatar.

Background: The Middle East region is predicted to have one of the highest prevalence of diabetes mellitus (DM) in the world. The risk of diabetes continues to increase worldwide and its public health burden is unevenly distributed across socioeconomic strata. This burden is not only related to health care costs, but also to indirect costs caused by loss of productivity from disability and premature mortality. Aim: This study aims to estimate the economics cost of type 2 Diabetes Mellitus [T2DM] among adults in Qatar using national data, and to quantify the potential effect of a suggested preventive intervention program. Design: It is an observational cohort study. Setting: The survey was based on registry at the Hamad General Hospital and Primary Health Care (PHC) centers in the State of Qatar. Subject: This study consisted of patients above 25 years of age with diagnosed diabetes mellitus registered at Hamad General Hospital and Primary Health Care (PHC) centers during January 2004 to July 2014. Methods: We developed a dynamic model in which actual incidence, prevalence, and life expectancy data are used and alternative assumptions about future trends in these parameters can be incorporated. Linear regression model has been performed to forecast the burden of diabetes in oil-rich country. Results: According to the dynamic model, a 10% increased in the number of diabetic patients in the State of Qatar from 33 610 in 2005 to 122 000 in 2012 (about 1% annually). The annual diabetes incidence rate was higher in women than in men during a period between 2005 to 2015 years. The static model forecasted as 10% increase over 10 years. The relative increase in prevalence of diabetes and number of diabetic people are higher in women than in men (16.6%; 17.5% and 18.4% in men vs. 22.6%; 23.8% and 25.1% in women). Most of the increase in prevalence of diabetes is projected to occur in younger age groups where it is estimated to increase among age groups of 50-59 years and above 60 years, respectively. Conclusion: The burden of diabetes in Qatar is markedly larger than proposed by IDF estimations - suggesting that Qatar would be one of the top 10 countries worldwide in diabetes prevalence. Family history of diabetes, consanguinity marriages', hereditary gene-environment interactions, poor nutrition in utero and in early life plus over nutrition in later life may also contribute to the current diabetes epidemic in Qatari's Arab populations. Finally, continuous training of primary health care professionals on diabetes care and prevention is an essential tool of improving diabetes in Qatar.

Relationship between patient satisfactions with diabetes care and treatment.

BACKGROUND: Measurement of treatment satisfaction in diabetes is important as it has been shown to be associated with positive outcomes, reduced disease cost and better health. AIM: The aim of this study was to assess the relationship between treatment satisfaction of diabetes patients and socioeconomic, clinical, medication adherence and health-related factors in Qatar. DESIGN: This is a cross-sectional study. SETTING: The survey was carried out in primary health care centers and hospitals from April 2010 to May 2011. SUBJECTS: Of a total of 3000 diabetic patients, 2582 patients gave their consent to take part in the study, with a response rate of 86.1%. MATERIALS AND METHODS: The Diabetes Treatment Satisfaction Questionnaire was used to measure the patient satisfaction. The modified Morisky Medication Adherence was used to measure medication taking behavior. A multivariate stepwise linear regression model was performed to identify factors independently associated with patients' satisfaction instrument. RESULTS: Of the studied patients, majority of the diabetes patients were Qataris (61.2%), married (86.1%), above secondary education (46.9%) and unemployed (28.6%). Diabetes patients who had professional jobs (3.97 ± 0.65; P = 0.009) and those who were staying alone had a significantly higher treatment satisfaction score (4.01 ± 0.64; P = 0.001) compared with the other patients. Patients who were taking tablets were significantly more satisfied with treatment (4.08 ± 0.60; P < 0.001). Diabetes patients of primary health care centers (3.96 vs. 3.80; P < 0.001) were more satisfied with treatment than patients visiting hospitals. Multivariate regression analysis revealed that age of the patient (P < 0.001), expatriates (P = 0.023), patients visiting hospitals (P < 0.001), treatment with insulin (P < 0.001) and any diabetes complications (P < 0.001) were significantly less satisfied with the treatment. CONCLUSION: The study findings revealed that patient satisfaction was positively associated with sociodemographic variables like high income, employment, married individuals and those with higher levels of education. We found a lower treatment satisfaction in patients with diabetes-related complications and insulin treatment.
