Economic Evaluation of an Integrated Care Program Compared to Conventional Care for Patients With Chronic Kidney Disease in Rural Communities of Thailand.

Introduction: An integrated care program for chronic kidney disease (CKD) in Thailand has shown its effectiveness in delaying the decline in kidney function, as evidenced by the Effectiveness of Integrated Care on Delaying Progression of Stages 3 to 4 CKD in Rural Communities of Thailand (ESCORT-1) randomized control trial and the ESCORT-2 prospective cohort study. Designed for sustainability within the primary healthcare system, the program optimizes the use of the existing workforce by fostering collaboration among local multidisciplinary care teams (MDCTs) and community care networks (CCNs). Methods: A Markov model with a lifetime horizon was used to conduct a cost-utility analysis from a societal perspective. Individual participant level data from ESCORT studies, national registries, and relevant literature were used to estimate model parameters. A budget impact analysis from the payer's perspective was also assessed over a 5-year period. Results: The integrated care program yielded a dominant result with 1.84 quality-adjusted life years (QALYs) gained with "less" lifetime cost, resulting in a negative incremental cost-effectiveness ratio (ICER). Probabilistic analysis showed that the intervention being cost-effective almost 100% of the time at the local willingness-to-pay threshold. The intervention maximized cost-effectiveness when delivered as early as possible, both in terms of age and stage. The budget impact analysis estimated that the introduction of the intervention could save about 7% of the Thai government's total health expenditure or 205 billion Thai-Baht ($5.9 billion) over 5 years with cost savings beginning from the third year onwards. Conclusion: The integrated care program for CKD offers potential benefits and cost savings for patients, caregivers, and payers. Future efforts should focus on the screening and implementation processes across various regions and healthcare settings.

Rationale, Design, and Intervention Development of a Mobile Health-Led Primary Care Program for Management of Type 2 Diabetes in Rural Thailand: Protocol for a SMARThealth Diabetes Study.

BACKGROUND: Noncommunicable diseases (NCDs), particularly diabetes and chronic kidney diseases, pose a significant health burden in Thailand, especially among socioeconomically disadvantaged populations. The existing primary health care system faces challenges in providing optimal care for NCDs due to inadequate primary care workforce. The SMARThealth program offers a technology-based solution to enhance NCD management through task-sharing among nonphysician health care workers. OBJECTIVE: This study aims to adapt and implement the SMARThealth Diabetes program in rural Thailand to improve diabetes management. The main objectives are to (1) adapt, validate, and integrate the SMARThealth Diabetes program for improving the management of type 2 diabetes mellitus at the primary health care level; and (2) to determine the feasibility and acceptability of the SMARThealth Diabetes program in rural communities of Thailand. METHODS: A pragmatic, type 2 hybrid effectiveness or implementation, parallel-group cluster randomized controlled trial of 12 months duration and involving 51 subdistrict health offices in rural communities of Kamphaeng Phet province, Thailand, will be conducted. The intervention arm will receive the SMARThealth Diabetes program, including workforce restructuring, clinical decision support system, and continuous performance monitoring, while the control arm will continue with usual practice. Data will be collected using the SMARThealth platform and will be stored on a server in Thailand. The primary outcome measure will be the change in mean hemoglobin A1c (HbA1c) measured at randomization and 12 months from randomization between the intervention and control clusters. Secondary outcomes will include the difference in change in albuminuria status, estimated glomerular filtration rate, systolic blood pressure, and low-density lipoprotein cholesterol level. The analysis for change in HbA1c between baseline and end of study will be performed using linear mixed models. Any imbalances between the 2 arms will be addressed by sensitivity analyses. Additionally, a mixed methods process evaluation will be conducted to assess the implementation process, that will include in-depth interviews and focus group discussions, in addition to the quantitative data collected during the implementation process. The qualitative data will be thematically analyzed to explore factors that promote or inhibit the implementation and maintenance of the program. RESULTS: The data collection commenced in November 2022, and the results will be ready for publication by the first quarter of 2025. Effectiveness of the intervention package will be assessed by change in mean HbA1c measures, and detailed feasibility, barriers, and enablers for the implementation of the intervention will be documented through a detailed process evaluation. CONCLUSIONS: The study protocol outlines a novel approach to enhancing diabetes management in rural Thailand through digital technology-based interventions that will facilitate task-sharing among health care workers. This can help inform future strategies for improving NCD care in low-resource settings globally.

Correlation of the Dietary Protein Intake between Those Estimated from a Short Protein Food-Recall Questionnaire and from 24-Hour Urinary Urea-Nitrogen Excretion in Stages 3-4 Chronic Kidney Disease Patients.

Introduction: High protein intake may accelerate progression of chronic kidney disease (CKD). Estimation of dietary protein intake (DPI) is indispensable for management of CKD, but to achieve optimum DPI is quite challenging in routine clinical practice. We recently studied a beneficial effect of utilizing integrated care on the management of CKD at the rural community level. In that study, we created a short protein food-recall questionnaire (S-PFRQ) as a working tool to estimate DPI of the CKD patients during home visit by community health personnel. Herein, we reported the initial evaluation of the reliability of S-PFRQ from our previous study. Objective: We compared the amount of DPI obtained from S-PFRQ with that obtained from protein-equivalent of total nitrogen appearance (PNA). Methods: In the previous ESCORT-2 study, 914 patients with CKD stage 3 or 4, who were living in the rural area of Thailand, were prospectively followed while receiving integrated care for 36 consecutive months. During home visits by community nurses from subdistrict health centers, dietary food recall was made, recorded in S-PFRQ, and DPI was obtained. Among these, sixty patients were randomly selected, and 24-h urine was collected for urinary urea-N and estimation of PNA. A correlation was made between DPI obtained from S-PFRQ and PNA. Results: The DPIs derived from S-PFRQ and PNA were 28.8 ± 14.8 and 39.26 ± 17.79 g/day, respectively. The mean difference and 95% CI between the 2 methods was -10.43 (-7.1 to -13.8) g/day, respectively (P < 0.001). Interclass correlation between these 2 methods was 0.24, P = 0.007. The difference between the 2 methods remained constant across different amounts of DPI. Conclusion: The DPI estimated from S-PFRQ significantly correlated to that from PNA. However, the S-PFRQ method yielded a DPI value which was about 10 g of protein or 25% less than the PNA method. Despite this amount of difference, this S-PFRQ is user-friendly and could be used during field work as an easy and simple tool for DPI estimation in resource-limiting condition.

Effectiveness of integrated care on delaying chronic kidney disease progression in rural communities of Thailand (ESCORT-2) trials.

AIM: We conducted a prospective cohort study to evaluate the effectiveness of an integrated care model on delaying chronic kidney disease (CKD) progression in routine clinical practice in rural primary care setting. METHODS: After enrolment, patients with stages 3 to 4 CKD patients from five district hospitals in a northern province of Thailand (400 km from Bangkok) received integrated care comprising hospital multidisciplinary care and home visits by community care teams. Clinical characteristics and biochemical data were collected at baseline and every 3-month interval thereafter for 36 months. The primary outcome was the rate of estimated glomerular filtration rate (eGFR) decline. RESULTS: Nine hundred and fourteen stage -3 and - 4 CKD patients were enrolled. The mean age of our cohort was 62 years. Diabetic kidney disease (DKD) was the main cause of CKD (53%) whereas hypertension was the most common co-morbidity (92%). The mean rate of eGFR decline was -0.92 mL/min/1.73 m2 /year. The rate of eGFR decline among patients with DKD was about three times faster than patients without DKD. Patients with higher blood pressure, metabolic acidosis, proteinuria or anaemia had a faster rate of eGFR decline. CONCLUSION: This integrated care model at the community level was effective in delaying CKD progression in routine clinical practice situation.
