Resolving the Dialysis Fiscal Trap: Macroeconomic Return and Healthcare Budget Impact of Paraprofessional Primary Care Buffers (A Decision-Analytic Markov Model)

STATUS: Working paper and open model, released as-is for independent replication and critique. Not peer-reviewed; not submitted for journal publication.Flow B (GDP) uses an author-developed DALY-to-output bridge (DALY × working-age share × per-capita GRP). Known limitations: (1) State 4 is a composite (ESRD, amputation, recurrent severe events) costed entirely at the hemodialysis tariff, and net OMS savings turn negative if the blended S4 cost falls below roughly 0.5M RUB per patient-year; (2) ΔHbA1c of −0.6% rests on one small quasi-experimental study, while −1.0% is a policy target, not an observed effect; (3) transition probabilities and the initial state distribution are not calibrated to registry data; (4) deterministic one-way sensitivity only, no PSA; (5) "1,527 ESRD cases prevented" denotes the difference in S4 prevalence at year 10, not cumulative incident cases.Replication and critique are welcome. Overview & Executive Summary This open-access repository contains the complete Health Economics and Outcomes Research (HEOR) working paper and the fully parameterized, interactive decision-analytic Markov cohort model evaluating the fiscal and macroeconomic return of frontline paraprofessional primary care buffers (quasi-Village Health Volunteers / Rural Health Assistants) in rural non-communicable disease control. Working Paper (PDF): Ovsepian_2026_Markov_Model_Rural_PHC_GDP.pdf Companion Decision-Analytic Model (Excel): PHC_Markov_DALY_GDP_Model.xlsx Dedicated Statutory Regulatory Archive: DOI: 10.5281/zenodo.23871546 Abstract Background: Regressive capitation adjustments and administrative austerity in low-density rural settlements frequently result in the structural insolvency of primary healthcare outposts (such as Russia's Feldsher-Midwife Stations, FAPs, operating at a -79.5% five-year margin). Fiscal decision-makers routinely view frontline rural outposts as passive social expenditure rather than productive capital investment. While integrating autonomous primary care concessions with paraprofessional community buffers—modeled on Thailand's Village Health Volunteers (VHVs) and the UK National Health Service's Community Health and Well-being Workers (CHWWs)—restores operational solvency and improves glycemic control in Type 2 Diabetes Mellitus (T2DM), its downstream impact on inpatient healthcare budgets and macroeconomic output remains unquantified. Methods: Following CHEERS 2022 and ISPOR-SMDM state-transition modeling guidelines, we developed a deterministic, 5-state cohort Markov model over a 10-year horizon (1-year cycle with half-cycle correction) for a rural T2DM cohort (N = 100,000; 30% working-age share). The intervention models 1 autonomous paramedic-concessionaire supported by 2–3 Rural Health Assistants (quasi-VHVs) receiving a non-crowding-out tax-exempt token allowance (8,000 RUB [86.50 USD/mo]; total program cost: 7,200 RUB [77.84 USD pt/yr]). Clinical effectiveness is calibrated using the theoretical policy target (ΔHbA1c = -1.0%) and the empirical Thai VHV trial effect (ΔHbA1c = -0.6%, raising controlled glycemia from 30% to 40%, p < 0.01; Sanguanprasit et al., 2016), mapped onto vascular endpoints via validated UKPDS 35 equations (Stratton et al., 2000). Background mortality is anchored in demographic monitoring by the Vishnevsky Institute of Demography (HSE University, 2025, ISSN 1726-2891), GBD 2021 Life Tables (The Lancet, 2024), and the Human Mortality Database (HMD). Economic evaluation follows a dual-stream framework discounted at 3.0% annually: (Flow A) direct single-payer (OMS) Diagnosis-Related Group (DRG/KSG) and statutory renal replacement tariffs (1,127,412 RUB [12,188 USD/yr] at 7,227 RUB [78.13 USD]/session under the 2025 TFOMS Sverdlovsk Tariff Agreement, Code A18.05.002); (Flow B) indirect macroeconomic productivity preserved via the WHO Human Capital Approach (DALY = YLL + YLD) valued conservatively at national mean per-capita GRP (1,280,000 RUB [13,838 USD/yr]). Results: Under the baseline target (ΔHbA1c = -1.0%, 75% outreach coverage), the intervention prevents 4,042 premature vascular deaths and 1,527 terminal combined/end-stage renal disease (ESRD) cases over 10 years, averting 56,913 discounted DALYs (17,074 in the working-age sub-cohort). Cumulative 10-year program costs (5,494.8M RUB [59.4M USD]) are more than doubled by 11,327.1M RUB (122.5M USD) in avoided acute inpatient DRG and dialysis expenditures, yielding net healthcare budget savings of +5,832.3M RUB (+63.1M USD; direct medical ROI of 2.06 : 1; dominant ICER of -102,478 RUB [-1,108 USD]/DALY). Preserved working-age health generates 21,854.5M RUB (236.3M USD) in direct GDP contribution, bringing total societal net economic benefit to 27,686.8M RUB (299.3M USD) and a societal Benefit-Cost Ratio of 6.04 : 1. Under the empirical Thai VHV shift (ΔHbA1c = -0.6%), the intervention remains strictly cost-saving within the healthcare budget alone (program costs: 5,457.3M RUB [59.0M USD]; gross OMS savings: 7,178.8M RUB [77.6M USD]; net OMS savings: +1,721.5M RUB [+18.6M USD]; medical ROI: 1.32 : 1; dominant ICER: -47,290 RUB [-511 USD]/DALY) while preserving 13,978.8M RUB (151.1M USD) in regional GDP and generating 15,700.4M RUB (169.7M USD) in total societal net benefit (Societal BCR: 3.88 : 1). Conclusions: Embedding paraprofessional community buffers within autonomous rural primary care outposts is a dominant, self-financing health technology. Ignoring frontline chronic disease outreach generates severe downstream fiscal penalties in tertiary hospital and dialysis care alongside substantial macroeconomic labor losses.
