The Volunteer Incarcerated Persons’ Health Assessment for Rehabilitation and Training Effectiveness (VIPHARTE): A Dual-Array Research Proposal for Correctional Wellness Monitoring in California

Objective: Little is published on health indices for incarcerated populations. Such information can enhance health services delivery with a view to optimize programming goals and reduce recidivism. Methods: Following IRB approval, the volunteer incarcerated persons' health assessment for rehabilitation and training effectiveness (VIPHARTE) will proceed on two tracks—Array I (retrospective) will comprise de-identified data from previously entered health records on all incarcerated adults in California state prisons (n > 90,000). Redacted weights taken on January 1st (baseline) will be anonymously tracked for each record with weight remeasured on 31st December for cohorts in 2017, 2021, and 2024. Age, gender, and self-identified ethnicity will be matched on each entry to document weight change (if any) before, during, and after COVID-19. Array II (prospective) will estimate current inmate wellness from biomarker tests offered to incarcerated volunteer participants (n=1000). These samples would be collected at previously booked primary care clinic visits, with specimens frozen for off-site batch analysis. VIPHARTE will focus on hematologic, metabolic, endocrine, and epigenomic stress parameters, some of which (20%) are already being collected at California correctional institutions. The remaining items (n = 24) will be completed by research partners from specialty laboratories at no additional cost. Results: Weight change patterns among the incarcerated are well documented but largely ignored, and require further study. Array I will be among the first datasets to clarify this phenomenon. VIPHARTE will also enable cross-comparisons with reference to COVID-19, where prison populations are known to have been particularly impacted. In Array II, new information on anemia, nutrition, infection, systemic inflammation, hepatic/renal function, endocrine status, and oxidative stressors as potential epigenomic modifiers will be aggregated from the volunteer cohort. Conclusion: Health assessments, either historical or real-time, taken directly from the incarcerated are scarce. When available, they bring value in shaping correctional health policy, budget prioritization, public workforce allocations, and overall awareness of needs within a vulnerable population. California operates 31 correctional institutions, including the world's largest women's prison. Treatment and care decisions for these incarcerated individuals develop inside a high-throughput managed care organization functioning as a system-within-a-system. Large tranches of its clinical data will provide raw resources to power Array I of VIPHARTE. Its prospective component (Array II) will gather original data on novel cell signaling elements contributed by representative volunteers, producing a detailed and overdue update concerning wellness strengths and weaknesses in this understudied group.
