Prediction of pharmaceutical and non-pharmaceutical expenditures associated with Diabetes Mellitus type II based on clinical risk. PLoS One 2024; 19:e0301860. [PMID: 38833461 PMCID: PMC11149868 DOI: 10.1371/journal.pone.0301860] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2022] [Accepted: 03/22/2024] [Indexed: 06/06/2024] Open
Abstract
OBJECTIVE To assess the effectiveness of different machine learning models in estimating the pharmaceutical and non-pharmaceutical expenditures associated with Diabetes Mellitus type II diagnosis, based on the clinical risk index determined by the analysis of comorbidities. MATERIALS AND METHODS In this cross-sectional study, we have used data from 11,028 anonymized records of patients admitted to a high-complexity hospital in Bogota, Colombia between 2017-2019 with a primary diagnosis of Diabetes. These cases were classified according to Charlson's comorbidity index in several risk categories. The main variables analyzed in this study are hospitalization costs (which include pharmaceutical and non-pharmaceutical expenditures), age, gender, length of stay, medicines and services consumed, and comorbidities assessed by the Charlson's index. The model's dependent variable is expenditure (composed of pharmaceutical and non-pharmaceutical expenditures). Based on these variables, different machine learning models (Multivariate linear regression, Lasso model, and Neural Networks) were used to estimate the pharmaceutical and non-pharmaceutical expenditures associated with the clinical risk classification. To evaluate the performance of these models, different metrics were used: Mean Absolute Percentage Error (MAPE), Mean Squared Error (MSE), Root Mean Squared Error (RMSE), Mean Absolute Error (MAE), and Coefficient of Determination (R2). RESULTS The results indicate that the Neural Networks model performed better in terms of accuracy in predicting pharmaceutical and non-pharmaceutical expenditures considering the clinical risk based on Charlson's comorbidity index. A deeper understanding and experimentation with Neural Networks can improve these preliminary results, therefore we can also conclude that the main variables used and those that were proposed can be used as predictors for the medical expenditures of patients with diabetes type-II. CONCLUSIONS With the increase of technology elements and tools, it is possible to build models that allow decision-makers in hospitals to improve the resource planning process given the accuracy obtained with the different models tested.

BMC Public Health 2023; 23:2411. [PMID: 38049796 PMCID: PMC10696789 DOI: 10.1186/s12889-023-17280-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2023] [Accepted: 11/21/2023] [Indexed: 12/06/2023] Open
Abstract
BACKGROUND The clinical characteristics of early-onset type 2 diabetes (T2D) patients are not fully understood. To address this gap, we conducted a cohort study to evaluate clinical characteristics and disease burden in the new-onset T2D population, especially regarding the progression of diseases. METHODS This cohort study was conducted using a population-based database. Patients who were diagnosed with T2D were identified from the database and were classified into early- (age < 40) and late-onset (age ≥ 40) groups. A descriptive analysis was performed to compare clinical characteristics and disease burden between early- and late-onset T2D patients. The progression of disease was compared using Kaplan‒Meier analysis. RESULTS A total of 652,290 type 2 diabetic patients were included. Of those, 21,347 were early-onset patients, and 300,676 were late-onset patients. Early-onset T2D patients had poorer glycemic control than late-onset T2D patients, especially at the onset of T2D (HbA1c: 9.3 [7.5, 10.9] for early-onset vs. 7.7 [6.8, 9.2] for late-onset, P < 0.001; random blood glucose: 10.9 [8.0, 14.3] for early-onset vs. 8.8 [6.9, 11.8] for late-onset, P < 0.001). Insulin was more often prescribed for early-onset patients (15.2%) than for late-onset patients (14.8%). Hypertension (163.0 [28.0, 611.0] days) and hyperlipidemia (114.0 [19.0, 537.0] days) progressed more rapidly among early-onset patients, while more late-onset patients developed hypertension (72.7% vs. 60.1%, P < 0.001), hyperlipidemia (65.4% vs. 51.0%, P < 0.001), cardiovascular diseases (66.0% vs. 26.7%, P < 0.001) and chronic kidney diseases (5.5% vs. 2.1%, P < 0.001) than early-onset patients. CONCLUSIONS Our study results indicate that patients with newly diagnosed early-onset T2D had earlier comorbidities of hypertension and hyperlipidemia. Both clinical characteristics and treatment patterns suggest that the degree of metabolic disturbance is more severe in patients with early-onset type 2 diabetes. This highlights the importance of promoting healthy diets or lifestyles to prevent T2D onset in young adults.

Abstract
Introduction The care for many patients with diabetes mellitus type 2 in the Netherlands, is contracted by a local care group. The healthcare providers, who collectively shape a care group, provide protocolled diabetes care. Differences exist between care groups in terms of their organizational and financial arrangements. These differences may result in variation in outcomes. The aim of this study is to assess whether variation in healthcare costs, diabetes complications and related hospital admissions on the level of care groups exist. Methods A quantitative cohort study was conducted. Patients who used diabetes medication (more than 180 days of defined daily doses per year) for the first time between the years 2014 and 2019 were included. Data were extracted from health insurance claims between 2014 and 2019. Generalized linear mixed models were used to analyse patient variation in healthcare costs (two and six years follow-up), diabetes-related complications and hospital admission days. Intraclass correlation coefficients were calculated to estimate the amount of variation that was attributable to the care groups. Results A large variation in outcome variables was observed between patients and a small variation between care groups. The intraclass correlation coefficient for long-term costs was 0.4%; for short-term costs between 0.1% and 0.3%; for complications 1% and for hospital days 4%. Discussion A large variation between patients with diabetes mellitus type 2 exists in terms of their healthcare costs and complications. In our study, care groups accounted minimally for this variation. A generalized linear mixed model in combination with year cohorts is a tool to study variations in the long-term outcomes of integrated care initiatives.

The Economic Burden of Hospital Costs on Families With Type 1 Diabetes Mellitus Children: The Role of Medical Insurance in Shandong Province, China. Front Public Health 2022; 10:853306. [PMID: 35602147 PMCID: PMC9121097 DOI: 10.3389/fpubh.2022.853306] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2022] [Accepted: 03/28/2022] [Indexed: 11/13/2022] Open
Abstract
Objective This study estimates the economic burden imposed on families by comparing the hospitalization costs of T1DM children with and without medical insurance in Shandong province. Methods Our data comprised 1,348 T1DM inpatient records of patients aged 18 years or younger from the hospitalization information system of 297 general hospitals in 6 urban districts of Shandong Province. Descriptive statistics are presented and regression analyses were conducted to explore the factors associated with hospitalization costs. Results Children with medical insurance had on average total hospitalization expenditures of RMB5,833.48 (US$824.02) and a hospitalization stay of 7.49 days, compared with the children without medical insurance who had lower hospitalization expenditures of RMB4,021.45 (US$568.06) and an average stay of 6.05 days. Out-of-pocket expenses for insured children were RMB3,036.22 (US$428.89), which is significantly lower than that of the uninsured children (P < 0.01). Out-of-pocket (OOP) expenditures accounted for 6% of the annual household income of insured middle-income families, but rose to a significant 25% of the annual income for low-income families. These OOP expenditures imposed a heavy economic burden on families, with some families experiencing long-term financial distress. Both insured and uninsured families, especially low-income families, could be tipped into poverty by hospitalization costs. Conclusion Hospitalization costs imposed a significant economic burden on families with children with T1DM, especially low-income insured and uninsured families. The significantly higher hospitalization expenses of insured T1DM children, such as longer hospitalization stays, more expensive treatments and more drugs, may reflect both excess treatment demands by parents and over-servicing by hospitals; lower OOP expenses for uninsured children may reflect uninsured children from low-income families forgoing appropriate medical treatment. Hospital insurance reform is recommended.

Abstract
OBJECTIVES This study aims to update the statistics on the economic burden of T2DM and to identify the factors affecting the economic costs of T2DM in China. METHODS This study conducts a systematic review of the existing literature that has reported on the direct economic costs (mainly the direct medical resource consumption) and indirect economic costs (mainly non-medical costs and intangible costs) of T2DM as of 31 May 2019. RESULTS The total expenditure on diabetes in China's western region is still relatively low. Additionally, the mean direct costs of T2DM are high in China's northern urban areas. However, compared to urban areas, in rural areas, the largest proportion of the total economic costs of T2DM is the mean indirect costs. Furthermore, age, sex, type and number of complications, type of medical insurance, diabetes duration, level of education, and income are the primary factors that influence the economic burden of T2DM. CONCLUSION There is a considerable economic burden associated with T2DM in China. Therefore, to address the economic burden of T2DM, it is vital to take measures to reduce the prevalence rate of diabetes.

Abstract
Objectives: To estimate the clinical and economic burden of type 2 diabetes (T2D) in established (EST) and emerging markets (EMG).Methods: Three systematic literature reviews were conducted in MEDLINE and Embase to capture all relevant publications reporting 1) the epidemiology of T2D and complications in T2D and 2) the economic burden of T2D and associated complications.Results: In total, 294 studies were included in this analysis. Evidence indicates a high and increasing overall prevalence of T2D globally, ranging up to 23% in EMG markets and 14% in EST markets. Undiagnosed cases were higher in EMG versus EST markets (up to 67% vs 38%), potentially due to a lack of education and disease awareness in certain regions, that could lead to important clinical and economic consequences. Poor glycemic control was associated with the development of several complications (e.g. retinopathy, cardiovascular diseases and nephropathy) that increase the risk of morbidity and mortality. Direct costs were up to 9-fold higher in patients with vs without T2D-related complications.Conclusions: The burden of T2D, related complications and inherent costs are higher in emerging versus established market countries. This review explores potential strategies to reduce costs and enhance outcomes of T2D treatment in developing countries.

Abstract
OBJECTIVE With the continuing rise in the global incidence of diabetes, the prevention of diabetes and control of associated medical expenses has become a public health issue worldwide. This study aims to identify the medical expenses of patients with diabetes in different regions of China and examine the differences in inpatient medical expenses and the impacts of them on these patients. STUDY DESIGN This study is a longitudinal analysis of medical expenses for inpatients with diabetes for different years; horizontal analysis of medical expenses among different regions; and literature review. METHODS Data were derived from China's Medical Insurance Department database. We selected inpatients with diabetes in the eastern, central, and western regions of China for the period 2013-2015 and randomly selected data through systematic sampling. RESULTS Among the 4150 patients with diabetes considered in this study, the patients' medical expenses were found to differ significantly across regions, years, ages, medical insurance types, medical institution levels, total medical expenses, medical insurance fund payments, and out-of-pocket (OOP) expenses. In addition, there were significant differences in total medical expenses for male and female patients. Furthermore, medical insurance type, patients' age, medical institution level, and year significantly influenced total medical expenses. CONCLUSIONS Inpatients with diabetes in different regions exhibited significant differences in total medical expenses, medical insurance fund payments, and OOP expenses. China should invest more in chronic disease treatment in its central and western regions, narrow the regional differences in medical expenses, and endeavor to ensure equity in the availability and cost of medical services. Moreover, patients with diabetes must be encouraged to access primary care to reduce their medical expenses.

Abstract
INTRODUCTION The treatment of diabetes requires extensive use of healthcare resources, resulting in high medical costs, which in turn places a heavy economic burden on society, patients and their families. METHODS A multi-stage stratified random sampling method was used to investigate 283 medical and health institutions in Hainan Province. The total medical expenses relating to diabetes in Hainan Province in 2016, institutional flow directions, the composition of service functions and the distribution of the healthcare costs to beneficiaries were analyzed based on the System of Health Account 2011. The STATA version 12.0 statistical software package was used to collate operation data, and SPSS software was used to carry out regression analysis on the factors affecting hospitalization costs. RESULTS In 2016, the total medical expenses for the treatment of diabetes in Hainan Province was 242.17 billion renminbi (RMB), of which 81.95% was spent in high-level hospitals and 14.71% was spent in medical institutions providing primary care. There was little difference between outpatient and hospitalization expenses (53.01 and 46.99%, respectively). Hospitalization accounted for 77.62% of the expenses of medical institutions providing primary care. Older patients were found to spend more on medical and drug expenditure. CONCLUSION The economic burden of healthcare expenses for the treatment of diabetes in Hainan Province is massive, and patient treatment is concentrated in large hospitals. It is necessary to inform patients to focus more on medical institutions that provide primary care, adjust the proportion of medical insurance reimbursement, control the cost of hospitalization and strengthen the healthcare management of middle-aged and elderly diabetic patients. Only in this way can costs be reduced and the economic burden be eased.

Abstract
PURPOSE Type 2 diabetes mellitus represents a significant health problem. Many studies have reported that intensive nutritional intervention by itself or in addition to medications is the best method to improve glycaemic control in type 2 diabetes mellitus. However, in clinical practice, dietary education is not implemented as an integral part in the management of type 2 diabetes mellitus. The purpose of this systematic review and meta-analysis is to analyse the scientific evidence concerning the role of nutritional intervention in the glycaemic control of type 2 diabetes mellitus. METHODS We searched Pubmed, Scopus, Cochrane Library and Web of Science databases from inception till May 2019 for randomised controlled trials (RCTs) that include dietary interventions in the management of patients with type 2 diabetes mellitus. RESULTS A total of 28 studies were included. Our results demonstrated that lifestyle interventions significantly lowered glycosylated haemoglobin (HbA1c) levels compared to the usual care for patients with type 2 diabetes mellitus, overall weighted mean difference, WMD = - 0.51 (- 0.67, - 0.35). Strategies combining individualized and group-based activities were the most effective, WMD = - 0.95 (- 1.24, - 0.66). Most of stratified analyses did not totally resolve heterogeneity, but improvement in HbA1c levels has been consistently observed. CONCLUSIONS The available evidence from RCTs shows that lifestyle intervention is more effective than the standard care regarding the glycaemic control of type 2 diabetic patients, particularly when there is a weight loss. It is time to translate this evidence to the primary health care practice. The protocol of the present systematic review was registered in PROSPERO, registration number CRD42018090469.

Abstract
Background The burden of diabetes has become a worldwide public health issue. Previous studies focused on the composition and influencing factors of hospitalization costs for insured patients. The aim of this study was to compare the economic burden of diabetic patients with and without medical insurance (MI) in China, from the aspects of types of medical costs and diabetic comorbidities. Material/Methods We identified 124 701 patients with type 2 diabetes mellitus in 2015 from electronic Hospitalization Summary Reports. The information on demographics, comorbidities, and hospitalization costs were extracted and evaluated. Differences between groups were analyzed by Mann-Whitney U test. Results The mean age of patients was 58.0±13.4 years. Hypertensive diseases (63.5%), ischemic heart diseases (21.3%), and chronic kidney disease (17.5%) were the most common comorbidities. The median hospitalization costs for diabetic patients with and without MI were 9485.0 RMB and 9104.0 RMB, respectively. The insured patients’ median out-of-pocket (OOP) cost was 1601.3 RMB, and they incurred more costs for laboratory tests, imaging examinations, and medical services, and less costs for prescribed drugs (p<0.05). Insured patients had higher costs when associated with hypertensive diseases, cerebrovascular diseases, and ischemic heart diseases (p<0.05). Conclusions Diabetic patients with MI have higher hospitalization costs than those without MI, but uninsured patients carry a heavier OOP burden. The MI system in China needs further improvement to reduce the economic burden of diabetes.

Korbel L, Easterling RS, Punja N, Spencer JD. The burden of common infections in children and adolescents with diabetes mellitus: A Pediatric Health Information System study. Pediatr Diabetes 2018; 19:512-519. [PMID: 29094435 DOI: 10.1111/pedi.12594] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/16/2017] [Revised: 08/19/2017] [Accepted: 09/19/2017] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND People with diabetes mellitus (DM) have increased infection risk. The healthcare utilization of pediatric and adolescent diabetic patients with infection is not well defined. This study evaluates the number of pediatric and adolescent patients with DM that seek medical treatment for infection management and assesses its socioeconomic impact. METHODS A retrospective analysis was performed using the Pediatric Health Information System (PHIS) database on children and adolescents with DM who presented to the Emergency Department (ED) or were hospitalized for infection management from 2008 to 2014. The PHIS database collects admission, demographic, and economic data from 44 freestanding children's hospitals across the United States. RESULTS In total, 123 599 diabetic patient encounters were identified (77% type 1 DM, 23% type 2 DM). ED visits and hospitalizations for type 1 DM and type 2 DM increased throughout the study period. Total charges for these encounters were greater than $250 million dollars per year and increased each year. Infection encounters make up more than 30% of that cost while accounting for only 14% of the visits. Respiratory infections were the most common type of infection followed by skin and soft tissue infections for both ED care and inpatient hospitalizations. Patients with infections had longer hospital length of stay and higher cost per day than those without infections. CONCLUSIONS Children and adolescents with type 1 and type 2 DM commonly present to the ED and require hospitalization for infection evaluation and management. Encounters with infection make up a large proportion of a growing economic burden on the United States' healthcare system. As the prevalence of DM grows, this burden can be expected to become even more significant. Cost-effective strategies for the prevention of infection in pediatric patients with DM are needed.

Abstract
Objectives:The aim of this study was to evaluate the direct costs of type 2 diabetes mellitus patients treated in a Brazilian public hospital.Methods:This was an exploratory retrospective cost-of-illness study with quantitative approach, using medical records of patients treated in a public hospital (2012–14), with at least one consultation over a period of 12 months. Data on patient's profile, exams, number of consultations, medications, hospitalizations, and comorbidities were collected. The cost per patient per year (pppy) was calculated as well as the costs related to glycated hemoglobin (HbA1c) values, using thresholds of 7 and 8 percent.Results:Data of 726 patients were collected with mean age of 62 ± 11 years (68.3 percent female). A total of 67.1 percent presented HbA1c > 7 percent and 44.9 percent > 8 percent. The median cost of diabetes was United States dollar (USD) 197 pppy. The median costs of medication were USD 152.49 pppy, while costs of exams and consultations were USD 40.57 pppy and 8.70 pppy, respectively. Thirty-eight patients (4 percent) were hospitalized and presented a median cost of 3,656 per patient per hospitalization with a cost equivalent to 53.1 percent of total expenses. Total costs of patients with HbA1c ≤ 7 percent were lower for this group and also costs of medications and consultations, whereas for patients with HbA1c ≤ 8 percent, only total costs and costs of medications were lower when compared with HbA1c > 8 percent patients.Conclusions:Medications and hospitalizations were the major contributor of diabetes expenses. Preventing T2DM, or reducing its complications through adequate control, may help avoid the substantial costs related to this disease.

Zhang JH, Yuan J, Wang T. Direct cost of dengue hospitalization in Zhongshan, China: Associations with demographics, virus types and hospital accreditation. PLoS Negl Trop Dis 2017; 11:e0005784. [PMID: 28771479 PMCID: PMC5557582 DOI: 10.1371/journal.pntd.0005784] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2017] [Revised: 08/15/2017] [Accepted: 07/06/2017] [Indexed: 11/24/2022] Open
Abstract
Background Zhongshan City of Guangdong Province (China) is a key provincial and national level area for dengue fever prevention and control. The aim of this study is to analyze how the direct hospitalization costs and the length of stay of dengue hospitalization cases vary according to associated factors such as the demographics, virus types and hospital accreditation. Method This study is based on retrospective census data from the Chinese National Disease Surveillance Reporting System. Totally, the hospital administrative data of 1432 confirmed dengue inpatients during 2013–2014 was obtained. A quantile regression model was applied to analyze how the direct cost of Dengue hospitalization varies with the patient demographics and hospital accreditation across the data distribution. The Length of Stay (LOS) was also examined. Main findings The average direct hospitalization cost of a dengue case in this study is US$ 499.64 during 2013, which corresponded to about 3.71% of the gross domestic product per capita in Zhongshan that year. The mean of the Length of Stay (LOS) is 7.2 days. The multivariate quantile regression results suggest that, after controlling potential compounding variables, the median hospitalization costs of male dengue patients were significantly higher than female ones by about US$ 18.23 (p<0.1). The hospitalization cost difference between the pediatric and the adult patients is estimated to be about US$ 75.25 at the median (p<0.01), but it increases sharply among the top 25 percentiles and reaches US$ 329 at the 90th percentile (p<0.01). The difference between the senior (older than 64 years old) and the adult patients increases steadily across percentiles, especially sharply among the top quartiles too. The LOS of the city-level hospitals is significantly shorter than that in the township-level hospitals by one day at the median (p<0.05), but no significant differences in their hospitalization costs. Conclusions The direct hospitalization costs of dengue cases vary widely according to the associated demographics factors, virus types and hospital accreditations. The findings in this study provide information for adopting hospitalization strategy, cost containment and patient allocation in dengue prevention and control. Also the results can be used as the cost-effective reference for future dengue vaccine adoption strategy in China. There is little literature estimating dengue disease burdens and treatment costs worldwide; however, still fewer studies focus on the hospitalization cost of Dengue. Using the quantile regression method to analyze the administrative data of 1,432 confirmed dengue inpatients in Zhongshan City (Guangdong, China) during 2013 and 2014, this study examines the relationship of the direct cost of Dengue hospitalization and the associated factors. The Length of Stay (LOS) was also examined. The findings in this study will help to explain how the hospitalization cost varies with associated factors, providing information for adopting hospitalization strategy, cost containment and patient allocation in dengue prevention and control, as well as reference for future dengue vaccine cost-effective analysis.

Abstract
INTRODUCTION Diabetes can be considered as a risk factor of several types of malignancy. Surgery is one of the primary methods of cancer treatment. The objective of this study was to evaluate the association between diabetes and hospital admissions to the surgery unit due to malignancy among elderly and middle-aged people. MATERIAL AND METHODS Data for analysis were taken from the medical records of 7,694 patients aged > 45, hospitalized in the General Surgery Ward in the Specialist District Hospital in Stalowa Wola in the Subcarpathian (Podkarpacie) Province, Poland, in the years 2010-2013. Among them malignancy was diagnosed in 652 patients and diabetes in 370 subjects. Ninety-three patients suffered from both diabetes and cancer. RESULTS Diabetes was associated with significantly elevated risk of hospitalization due to malignancy compared with the non-diabetic population, odds ratio (OR) 4.051 (95% confidence interval: 3.154-5.203), p < 0.001. Among people with diabetes, elderly patients (> 65 years) had higher risk of hospital admission due to cancer compared with the middle-aged population, OR = 5.238 (2.873-9.550), p < 0.001. Also, urban residents had higher risk compared with rural inhabitants, OR = 2.272 (1.375-3.752), p = 0.002. CONCLUSIONS Patients with diabetes, especially elderly and urban inhabitants, are at high risk of hospital admission due to malignancy. This indicates the need for oncological vigilance in such patients for early detection and treatment of cancers common in this population.
