Kidney Disease among People Who Are Incarcerated

Disparities in the Prevalence of Urinary Diseases Among Prisoners in Taiwan: Population-Based Cross-Sectional Study

Background

Prisoner health is a major global concern, with prisoners often facing limited access to health care and enduring chronic diseases, infectious diseases, and poor mental health due to unsafe prison environments, unhygienic living conditions, and inadequate medical resources. In Taiwan, prison health is increasingly an issue, particularly concerning urinary diseases such as urinary tract infections. Limited access to health care and unsanitary conditions exacerbate these problems. Urinary disease epidemiology varies by sex and age, yet studies in Asia are scarce, and comprehensive data on urinary diseases in Taiwanese prisons remain limited.

Objective

This study aimed to investigate the prevalence of urinary diseases among Taiwanese prisoners and explore the differences in disease prevalence between men and women, as well as across different age groups.

Methods

This study used data on prisoners from the National Health Insurance Research Database covering the period from January 1 to December 31, 2013. Prisoners covered by National Health Insurance who were diagnosed with urinary diseases, identified by ICD-9-CM (International Classification of Diseases, Ninth Revision, Clinical Modification) codes 580-599 based on their medical records, and had more than one medical visit to ambulatory care or inpatient services were included. Sex- and age-stratified analyses were conducted to determine the differences in the prevalence of urinary diseases.

Results

We examined 83,048 prisoners, including 2998 with urinary diseases. The overall prevalence of urinary system diseases among prisoners was 3.61% (n=2998; n=574, 6.64% in men and n=2424, 3.26% in women). The prevalence rate in men was significantly lower than that in women (prevalence ratio: 0.46, P<.001). In age-stratified analysis, the prevalence rate among prisoners aged >40 years was 4.5% (n=1815), compared to 2.77% (n=1183) in prisoners aged ≤40 years. Prisoners aged >40 years had a higher prevalence (prevalence ratio: 1.69, P<.001). Other disorders of the urethra and urinary tract (ICD-9-CM: 599), including urinary tract infection, urinary obstruction, and hematuria, were the most prevalent diseases of the urethra and urinary tract across age and sex groups. Women and older prisoners had a higher prevalence of most urinary tract diseases. There were no significant sex-specific differences in adjusted prevalence ratios for acute glomerulonephritis, nephrotic syndrome, kidney infections, urethritis (nonsexually transmitted), or urethral syndrome. However, based on the age-specific adjusted prevalence ratio analysis, cystitis was more prevalent among younger prisoners (prevalence ratio: 0.69, P=.004).

Conclusions

Urinary system infections and inflammation are common in prisons. Our findings advocate for policy reforms aimed at improving health care accessibility in prisons, with a particular focus on the needs of high-risk groups such as women and older prisoners. Further research linking claims data with prisoner information is crucial to providing more comprehensive medical services and achieving health equity.

A Scoping Review of Organ Transplantation in Populations Experiencing Incarceration

Despite an aging confined population, the current state of organ transplantation in carceral systems is largely unknown. This scoping review aimed to assess the literature on organ transplantation in populations experiencing incarceration. The review used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for a scoping review. Included references were published between January 2000 and January 2022 in PubMed, Cumulative Index to Nursing and Allied Health Literature via EBSCO, EMBASE.com, PsycInfo via EBSCO, Sociological Abstracts via ProQuest, and Scopus. Two reviewers conducted title and abstract screening, full-text review, and data extraction in order to generate common themes. The initial search yielded 3,225 studies, and 2,129 references underwent screening. Seventy studies underwent full-text review, and 10 met inclusion criteria. These studies revealed heterogeneous perspectives and policies by providers and transplant centers regarding transplant consideration of individuals with incarceration history or current involvement. Two studies on a kidney transplant program for patients experiencing incarceration showed transplant as a sustainable and potentially superior option for people who are incarcerated, as compared with chronic hemodialysis. Literature on transplantation for populations experiencing incarceration is sparse. More research is required to understand the demand for transplants and the ethical implications of the heterogeneous perspectives and policies on practice patterns.

Healthcare Disparities and the Impact on Mortality in Incarcerated Patients

This article addresses the healthcare disparities and potential impact on mortality among incarcerated patients with chronic kidney disease (CKD). Incarcerated individuals are more likely to suffer from acute and chronic health conditions and have inconsistent access to healthcare services. Demographic trends, behavioral health trends, and lack of insurance coverage are major contributing factors to healthcare disparities among incarcerated individuals. This article highlights the need for a new model of care, which includes clinical programs focusing on the transition period from incarceration to the community and linking individuals to post-incarceration healthcare utilizing community health workers and clinicians to establish rapport with individuals prior to their release. Addressing healthcare disparities and providing adequate healthcare to incarcerated individuals is crucial because a conviction should not deprive an individual of basic human rights, including the right to healthcare.

Challenging Health Inequities in Incarceration: a Call for Equitable Care for Kidney Disease and Hypertension

PURPOSE OF REVIEW

To review the current literature on care of hypertension and chronic kidney disease for people who are currently and formerly incarcerated, and to make recommendations for improving outcomes.

RECENT FINDINGS

There is a growing body of literature describing care for kidney disease and hypertension for incarcerated and formerly incarcerated individuals that documents the provision of care itself, notably that many jails contract with private companies; the system is not designed to provide sustained, chronic disease care; and the transition from incarceration to community is fraught with gaps in care. However, deficiencies in data collection and regulation still limit our understanding of the quality of care provided in jails and prisons. Furthermore, more data is needed to understand the impact of structural racism in the criminal legal system on overall disparities in care for hypertension and kidney disease. Insurance coverage rates for people who were formerly incarcerated continue to be lower than the general population despite Medicaid expansion in many states. There is little recent data regarding kidney replacement therapy for this population despite known variation in dialysis modalities and transplant programs by state. Transitions clinics, which connect people who were formerly incarcerated with care in the community upon release, are growing and are important avenues by which to deliver care. People who are incarcerated are disproportionately affected by hypertension and kidney disease, yet data regarding the extent of these inequities and availability of quality care is lacking. More work is needed to understand the care of individuals with kidney disease and hypertension in prisons and to improve outcomes for these common chronic conditions. Both providing effective treatment of kidney disease and hypertension in prisons and jails and providing coordinated, quality transition to community care upon release represents an important opportunity for reform in care for a marginalized population.

Social Determinants of Health Impacting Access to Renal Dialysis for Racial/Ethnic Minorities

Although widespread, the burden of disease presented by chronic kidney disease (CKD) is not equally distributed among all demographics. Examining the social determinants of health (SDOH) that relate to barriers to renal dialysis care in CKD can help to prevent future disparities. There has not been a study addressing the social factors that create barriers to care for ethnic minority patients with CKD. The aim of this scoping review is to address the SDOH that affects access to renal dialysis for ethnic minority patients in the United States. This study was based on the protocol published by the Joanna Briggs Institute. A total of 349 studies were identified from PubMed, EBSCOhost, and Embase. Each article was screened against population, concept, and context criteria in order to be considered for inclusion. The population was determined to be adults of all genders from underrepresented minority populations. The selected concept was SDOH. The context of this study was the United States population. From the articles selected by the search criteria, neighborhood of residence, mental health care access, glomerular filtration rate (GFR) methodology, socioeconomic status (SES), language barriers, immigration status, and military rank were identified as SDOH affecting access to renal dialysis care. While this study identified four social determinants, more research is needed for the investigation of other possible SDOH contributing to disparities related to CKD and access to renal dialysis care.

High Risk of Substance Use Disorder-Related Outcomes in Veterans Released from Correctional Facilities in Mid to Late Life

BACKGROUND

Veterans Affairs (VA) is likely to encounter a growing number of veterans returning to the community in mid to late life following incarceration (i.e., experiencing reentry). Yet, rates of negative health outcomes due to substance use disorders (SUDs) in this population are unknown.

OBJECTIVE

To determine risk of and risk factors for SUD-related emergency department visits and inpatient hospitalizations (ED/IPH) and overdose death among older reentry veterans compared with never-incarcerated veterans.

DESIGN

Retrospective cohort study using national VA and Medicare healthcare systems data.

PARTICIPANTS

Veterans age  ≥50, incarcerated for  ≤5 consecutive years, and released between October 1, 2010, and September 30, 2017 (N = 18,803), were propensity score-matched 1:5 with never-incarcerated veterans (N = 94,015) on demographic characteristics, reason for Medicare eligibility, and SUD history.

MAIN MEASURES

SUD-related ED/IPH (overall and substance-specific) were obtained from in-/outpatient VA health services and CMS data within the year following release date/index date (through September 30, 2018). Overdose death within 1 year was identified using the National Mortality Data Repository. Fine-Gray proportional hazards regression compared risk of SUD-related ED/IPH and overdose death between the two groups.

RESULTS

The number of SUD-related ED/IPHs and overdose deaths was 2470 (13.1%) and 72 (0.38%) in the reentry sample versus 4402 (4.7%) and 198 (0.21%) in the never-incarcerated sample, respectively. Mid-to-late-life reentry was associated with higher risk of any SUD-related ED/IPH (13,136.2 vs. 2252.8 per 100,000/year; adjusted hazard ratio [AHR] = 2.19; 95% confidence interval [CI] = 2.08, 2.30) and overdose death (382.9 vs. 210.6 per 100,000/year; AHR = 2.24, 95% CI = 1.63, 3.08).

CONCLUSIONS

Older reentry veterans have more than double the risk of experiencing SUD-related ED/IPH (overall and substance-specific) and overdose death, even after accounting for SUD history and other likely confounders. These findings highlight the vulnerability of this population. Improved knowledge regarding SUD-related negative health outcomes may help to tailor VA reentry programming.

Morphological brain alterations in dialysis- and non-dialysis-dependent patients with chronic kidney disease

To 1) investigate the morphological brain-tissue changes in patients with dialysis- and non-dialysis-dependent chronic kidney disease (CKD); 2) analyze the effects of CKD on whole-brain cortical thickness, cortical volume, surface area, and surface curvature; and 3) analyze the correlation of these changes with clinical and biochemical indices. This study included normal controls (NCs, n = 34) and patients with CKD who were divided into dialysis (dialysis-dependent chronic kidney disease [DD-CKD], n = 26) and non-dialysis (non-dialysis patients who underwent cranial magnetic resonance imaging scans [NDD-CKD], n = 26) groups. Cortical thickness, volume, surface area, and surface curvature in each group were calculated using FreeSurfer software. Brain morphological indicators with statistical differences were correlated with clinical and biochemical indicators. Patients with CKD exhibited a significant and widespread decrease in cortical thickness and volume compared with NCs. Among the brain regions associated with higher neural activity, patients with CKD exhibited more significant morphological changes in the paracentral gyrus, transverse temporal gyrus, and lateral occipital cortex than in other brain regions. Cortical thickness and volume in patients with CKD correlated with blood pressure, lipid, hemoglobin, creatinine, and urea nitrogen levels. The extent of brain atrophy was further increased in the DD-CKD group compared with that in the NDD-CKD group. Patients with CKD potentially exhibit a certain degree of structural brain-tissue imaging changes, with morphological changes more pronounced in patients with DD-CKD, suggesting that blood urea nitrogen and dialysis may be influential factors in brain morphological changes in patients with CKD.
