Diabetes increases preventative sickness and costs healthcare and productivity. Type 2 diabetes and macrovascular disease consequences cause most diabetes-related costs. Type 2 diabetes greatly costs healthcare institutions, reducing economic productivity and efficiency. This cost of illness (COI) analysis examines the direct and indirect costs of treating and managing type 1 and type 2 diabetes mellitus. According to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, Cochrane, PubMed, Embase, CINAHL, Scopus, Medline Plus, and CENTRAL were searched for relevant articles on type 1 and type 2 diabetes illness costs. The inquiry returned 873 2011–2023 academic articles. The study included 42 papers after an abstract evaluation of 547 papers. Most articles originated in Asia and Europe, primarily on type 2 diabetes. The annual cost per patient ranged from USD87 to USD9,581. Prevalence-based cost estimates ranged from less than USD470 to more than USD3475, whereas annual pharmaceutical prices ranged from USD40 to more than USD450, with insulin exhibiting the greatest disparity. Care for complications was generally costly, although costs varied significantly by country and problem type. This study revealed substantial heterogeneity in diabetes treatment costs; some could be reduced by improving data collection, analysis, and reporting procedures. Diabetes is an expensive disease to treat in low- and middle-income countries, and attaining Universal Health Coverage should be a priority for the global health community.

The relationship between stages of chronic hepatitis B liver disease and health-related quality of life (HRQoL) is an important aspect of the overall management of hepatitis B virus (HBV) infection, yet is not well characterized. Consequently we sought to examine HRQoL in HBV patients, stratified by disease severity, compared with normal controls and hypertensive patients, using the Short Form 36 Health Survey (SF-36) and the EQ-5D self-report questionnaire. Univariate and multivariate analyses were then performed. A total of 432 HBV (156 asymptomatic carriers, 142 chronic hepatitis B, 66 compensated cirrhosis, 24 decompensated cirrhosis, 22 hepatocellular carcinoma, and 22 post–liver transplant) patients, 93 hypertensive patients, and 108 normal controls participated in the study. Multivariate analysis showed that normal controls and asymptomatic carriers had similar SF-36 scores, which were better than those for hypertensive patients, but with development of chronic hepatitis B and compensated cirrhosis, showed a significant decrease in general health and the mental dimension, whereas those with advanced liver disease (decompensated cirrhosis and hepatocellular carcinoma) had significantly lower scores in all components (P < 0.05), indicating that the physical component deteriorates only with advanced liver disease. Similar results were obtained with EQ5D. Post–liver transplant patients had similar HRQoL to patients with decompensated cirrhosis and hepatocellular carcinoma, although there was a trend toward improvement. Conclusion: Our results showed that HRQoL in asymptomatic carriers is comparable to those of normal controls and better than hypertensive patients, but deteriorates with disease progression, initially in general health and mental dimensions, but with advanced disease all dimensions are affected.

Background: Diabetes is a major chronic illness that negatively influences individuals and society. Therefore, this research aimed to analyze and evaluate the cost associated with diabetes management, specific to the Pakistani Type 2 diabetes population. Research scheme and methods: A survey randomly collected information and data from diabetes patients throughout Pakistan out-patient clinics. Direct and indirect costs were evaluated, and data were analyzed with descriptive and inferential statistics. Results: An overall of 1839 diabetes patients participated in the study. The results have shown that direct and indirect costs are positively associated with the participants’ socio-demographic characteristics, except for household income and educational status. The annual total cost of diabetes care was USD 740.1, amongst which the share of the direct cost was USD 646.7, and the indirect cost was USD 93.65. Most direct costs comprised medicine (USD 274.5) and hospitalization (USD 319.7). In contrast, the productivity loss of the patients had the highest contribution to the indirect cost (USD 81.36). Conclusion: This study showed that direct costs significantly contributed to diabetes’s overall cost in Pakistan and overall diabetes management estimated to be 1.67% (USD 24.42 billion) of the country’s total gross domestic product. The expense of medications and hospitalization mostly drove the direct cost. Additionally, patients’ loss of productivity contributed significantly to the indirect cost. It is high time for healthcare policymakers to address this huge healthcare burden. It is time to develop a thorough diabetes management plan to be implemented nationwide.

Background: Kidney failure is a global health problem with a worldwide mean prevalence rate of 13.4%. Kidney failure remains symptomless during most of the early stages until symptoms appear in the advanced stages. Kidney failure is associated with a decrease in health-related quality of life (HRQOL), deterioration in physical and mental health, and an increased risk of cardiovascular morbidity and mortality. This study aimed to evaluate the factors associated with decreased HRQOL and other factors affecting the overall health of patients. Another objective was to measure how medication adherence and depression could affect the overall HRQOL in patients with kidney failure. Methodology: The study used a prospective follow-up mix methodology approach with six-month follow-ups of patients. The participants included in the study population were those with chronic kidney disease grade 4 and kidney failure. Pre-validated and translated questionnaires (Kidney Disease Quality of Life-Short Form, Hamilton Depression Rating Scale Urdu Version, and Morisky Lewis Greens Adherence Scale) and assessment tools were used to collect data. Results: This study recruited 314 patients after an initial assessment based on inclusion criteria. The mean age of the study population was 54.64 ± 15.33 years. There was a 47.6% male and a 52.4% female population. Hypertension and diabetes mellitus remained the most predominant comorbid condition, affecting 64.2% and 74.6% of the population, respectively. The study suggested a significant (p < 0.05) deterioration in the mental health composite score with worsening laboratory variables, particularly hematological and iron studies. Demographic variables significantly impact medication adherence. HRQOL was found to be deteriorating with a significant impact on mental health compared to physical health. Conclusions: Patients on maintenance dialysis for kidney failure have a significant burden of physical and mental symptoms, depression, and low HRQOL. Given the substantial and well-known declines in physical and psychological well-being among kidney failure patients receiving hemodialysis, the findings of this research imply that these areas related to health should receive special attention in the growing and expanding population of kidney failure patients.
