State-of-the-Art Review: Evaluation and Management of Delusional Infestation.

Delusional infestation is a condition encountered frequently by healthcare professionals across a variety of specialties in which patients have a fixed, false belief that they are infested with living creatures, such as bugs, parasites, worms, or mites, or nonliving objects, such as fibers. Delusional infestation can be debilitating for patients, who not only present with intense psychological distress and physical discomfort but are also at risk of developing numerous dermatological and psychiatric complications. This condition poses unique diagnostic challenges, as these symptoms can occur secondary to many metabolic or infectious causes, as well as unique treatment challenges, with patients frequently refusing psychiatric care and consequently seeking evaluation by other healthcare professionals. In this review, we aim to use existing literature to provide clinicians in infectious diseases or other specialties with sufficient clinical context and treatment guidance for the appropriate management of delusional infestation.

COVID-19 and influenza vaccine uptake in women with criminal-legal system involvement.

OBJECTIVE: Given their vulnerable health status and resource constraints, the perspectives of women with criminal-legal involvement (WCLI) are important but not usually represented in the literature on vaccine interest and vaccine hesitancy. This study aims to examine how the COVID-19 pandemic and vaccine affected the influenza vaccine uptake among WCLI. METHODS: A cross-sectional secondary analysis was conducted using data collected from the Tri-City study, which followed WCLI in three U.S. cities from 2019 to 2023. We mapped the distribution of influenza vaccine uptake in 2019-2023 and developed a composite outcome that reflected participants' patterns of Y/N to influenza vaccine, which were categorized into four groups: Influenza Vaccine Supportive, Influenza Vaccine Adaptive, Influenza Vaccine Discontinued, and Influenza Vaccine Resistant. RESULTS: Out of 507 people: 23.7% were Supportive, 8.5% Adaptive, 15.2% Discontinued and 38.3% Resistant. People who received the COVID vaccine had significantly lower odds of being identified as Discontinued (OR = 0.42, 95%CI = 0.20-0.87, p = .020) and Resistant (OR = 0.23, 95%CI = 0.13-0.43, p < .001), compared to the Supportive group. Mistrust toward COVID-19-related information was a significant independent predictor of being Adaptive (OR = 1.59, 95%CI = 1.08-2.35, p = .019), Discontinued (OR = 1.61, 95%CI = 1.15-2.25, p = .006), and Resistant (OR = 1.54, 95%CI = 1.19-2.00, p < .001) relative to Supportive. CONCLUSIONS: Vaccine hesitancy poses significant challenges to public health efforts, with apparent dampening effect across vaccines. Public health messaging and clinical interactions informed by best practices in communication tailored to the lived experience of all people, including women with criminal-legal system involvement, will be necessary to inform future interventions aimed at increasing vaccine uptake.

Operationalization of Status Neutral Human Immunodeficiency Virus Care for Criminal-Legal Involved Populations.

The United States has the highest number of people incarcerated in the world. Criminal-legal involved populations, including people who are incarcerated in jails and prisons and people who are under community carceral control through probation or parole are at an increased risk for human immunodeficiency virus (HIV). Increasing access to HIV testing, treatment and prevention is necessary to curb the HIV epidemic. This chapter outlines the history of HIV testing in jails and prisons and suggests a Status Neutral HIV Care Framework for improving access to HIV prevention services.

National HIV and HCV Screening Rates for Hospitalized People who Use Drugs Are Suboptimal and Heterogeneous Across 11 US Hospitals.

Background: To end the HIV and hepatitis C virus (HCV) epidemics, people who use drugs (PWUD) need more opportunities for testing. While inpatient hospitalizations are an essential opportunity to test people who use drugs (PWUD) for HIV and HCV, there is limited research on rates of inpatient testing for HIV and HCV among PWUD. Methods: Eleven hospital sites were included in the study. Each site created a cohort of inpatient encounters associated with injection drug use. From these cohorts, we collected data on HCV and HIV testing rates and HIV testing consent policies from 65 276 PWUD hospitalizations. Results: Hospitals had average screening rates of 40% for HIV and 32% for HCV, with widespread heterogeneity in screening rates across facilities. State consent laws and opt-out testing policies were not associated with statistically significant differences in HIV screening rates. On average, hospitals that reflexed HCV viral load testing on HCV antibody testing did not have statistically significant differences in HCV viral load testing rates. We found suboptimal testing rates during inpatient encounters for PWUD. As treatment (HIV) and cure (HCV) are necessary to end these epidemics, we need to prioritize understanding and overcoming barriers to testing.

Guiding the Implementation of Wastewater-based Surveillance for Carceral Infection Control with Perspectives from People with Lived Experience of Incarceration during the COVID-19 Pandemic.

Background: Little guidance exists on best practices for implementing and sustaining wastewater-based surveillance (WBS) for SARS-CoV-2 in carceral settings. To ensure alignment with priorities of stakeholders, we aimed to understand the perspectives of persons with lived experience (PLE) of jail who were incarcerated during the height of the COVID-19 pandemic on infection control. Methods: We recruited two PLE at each of four jails: Cook County (IL), Fulton County (GA), Middlesex County (MA), and Washington DC. Focus Group Discussion (FGD) guides followed the Consolidated Framework for Implementation Research (CFIR). Two FGDs focusing on lived experience with jail infection control protocol and WBS were conducted, and six Key Informant (KI) interviews followed to gain insights on communicating WBS results. We used a combination of deductive thematic analysis based on CFIR constructs and inductive analysis to capture emergent themes. Results: Themes from FGDs included: (1) variable experiences with COVID-19 infection control protocols including intake processes, individual testing, isolation and quarantine, (2) the perceived attitudes of fellow residents and staff surrounding COVID-19 mitigation in a carceral setting; and (3) perceived benefits and challenges involving WBS implementation and messaging. KIs emphasized 1) The importance of straightforward health messaging and trustworthiness in the communication of WBS results, 2) Support for enhanced health education around outbreaks, and 3) Receptiveness to WBS being used as a tool to measure common infectious agents (i.e., influenza) but hesitancy regarding its application to conditions such as HIV and illicit drug use. PLE articulated support of robust infection control programs and receptiveness to expanding WBS if conducted in a non-stigmatizing manner. Conclusion: Perspectives from PLE can help shape the infection control programs for future outbreaks and inform the expansion of WBS implementation in carceral facilities. It will be important to consider the voices of current and former residents, as receivers of care, to promote an environment conducive to comprehensive infection control. In addition to having infection control programs consistently execute set protocols and educate all stakeholders, PLE identified collaboration between jail staff and residents, and clear communication around program expectations as priorities. Findings from this qualitative study can be shared with jail decision makers and the perceived engagement of stakeholders can be measured.

Perspectives on benefits and risks of creation of an "injection drug use" billing code.

People with substance use disorder (SUD) face barriers to prevention and treatment services, increasing risk for hospitalization and death. Injection drug use (IDU) can lead to an increased risk of overdose and infections. However, identifying people who inject drugs (PWID) within healthcare systems is challenging. International Classification of Disease (ICD-10) codes are used for billing and tracking healthcare utilization. In this commentary, experts in the field weigh the benefits and risks of creating an IDU-specific ICD-10 code. Potential benefits include earlier identification, better access to health services, and improved systems of resource allocation. Potential risks include further stigmatization of PWID and, if not tied to financial reimbursement, low rates of code utilization. As the current systems of identifying PWID are lacking, we feel that a guided operationalization of an ICD code to identify PWID could improve quantitative and epidemiological research accuracy and, therefore, support the health and well-being of PWID.

Strategies to Improve Patient-Centered Care for Drug Use-Associated Infective Endocarditis: JACC Focus Seminar 2/4.

Drug use-associated infective endocarditis (DUA-IE) is a major cause of illness and death for people with substance use disorder (SUD). Investigations to date have largely focused on advancing the care of patients with DUA-IE and included drug use disorder treatment, decisions about surgery, and choice of antibiotics during the period of hospitalization. Transitions from hospital to outpatient care are relatively unstudied and frequently a key factor of uncontrolled infection, continued substance use, and death. In this paper, we review the evidence supporting cross-disciplinary care for people with DUA-IE and highlight domains that need further clinician, institutional, and research investment in clinicians and institutions. We highlight best practices for treating people with DUA-IE, with a focus on addressing health disparities, meeting health-related social needs, and policy changes that can support care for people with DUA-IE in the hospital and when transitioning to the community.

Medicaid Inmate Exclusion Policy and Infectious Diseases Care for Justice-Involved Populations.

The Medicaid Inmate Exclusion Policy (MIEP) prohibits using federal funds for ambulatory care services and medications (including for infectious diseases) for incarcerated persons. More than one quarter of states, including California and Massachusetts, have asked the federal government for authority to waive the MIEP. To improve health outcomes and continuation of care, those states seek to cover transitional care services provided to persons in the period before release from incarceration. The Massachusetts Sheriffs' Association, Massachusetts Department of Correction, Executive Office of Health and Human Services, and University of Massachusetts Chan Medical School have collaborated to improve infectious disease healthcare service provision before and after release from incarceration. They seek to provide stakeholders working at the intersection of criminal justice and healthcare with tools to advance Medicaid policy and improve treatment and prevention of infectious diseases for persons in jails and prisons by removing MIEP barriers through Section 1115 waivers.

A health literacy analysis of online patient-directed educational materials about mycobacterium avium complex.

Introduction: Mycobacterium avium complex (MAC) is a complex lung infection requiring multi-disciplinary approach and management. Due to limited clinician-patient interactions, clinicians may refer patients to online resources to learn about the diagnosis, prognosis, and treatment of MAC. The American Medical Association (AMA) recommends educational materials be written at a sixth-grade reading level and the National Institutes of Health (NIH) recommends that patient education materials be written at an eighth-grade reading level; however, several evaluations found these materials inaccessible due to high literacy levels. To date, there has never been a health literacy assessment of MAC patient education materials. The study aims to assess the health literacy of online patient education materials about MAC. Methods: The patient education materials were evaluated for readability, actionability, understandability and clarity. Readability was assessed through the Flesch-Kincaid Grade Level Scale (FkGL), SMOG Index, Coleman Liau Index (CLI), Gunning Fog Index (GFI), and Automated Readability Index (ARI). Actionability and understandability was evaluated using the Patient Education Materials Assessment Tool (PEMAT). The Centers for Disease Control (CDC) Clear Communication Index (CCI) was used to assess clarity. Results: Ten patient education resources were evaluated: CDC, Cleveland Clinic, Mayo Clinic, JAMA, American Thoracic Society (ATS), National Jewish Health, UpToDate, CHEST, WebMD, and Medline. The mean readability scores were as follows: FkGL (9.76), SMOG index (9.82), CLI (13.54), GFI (11.66), ARI (9.15). Four patient education materials were written at a sixth-grade reading level and eight patient education materials were written at an eighth-grade reading level. The majority of the materials received a passing score for understandability but failed to achieve a passing score for actionability. Cleveland Clinic, JAMA, and ATS all received a passing clarity score, indicating that they are easy to read. No patient education materials were available on UpToDate. Conclusion: Most patient education materials scored poorly for actionability and clarity while scoring highly for readability and understandability. This study should serve as a guide for clinicians interested in offering online education materials to their patients. Increasing access to readable MAC educational materials should be a priority for those working at the intersection of public health, clinical care, and communications.

Effect of Antibiotic Administration Before Joint Aspiration on Synovial Fluid White Blood Cell Count in Native Joint Septic Arthritis.

Background: This study was performed to assess the impact of preaspiration antibiotics on synovial fluid analysis and timing of operative treatment in native-joint septic arthritis. Methods: We performed a retrospective record review of adult patients from an urban level 1 trauma center with native joint septic arthritis in 2015-2019, identified by means of codes from the International Classification of Diseases (Ninth Revision and Tenth Revision). Univariate and multivariate analyses were performed to determine whether antibiotics were associated with lower synovial fluid white blood cell counts (WBCs), the percentage of polymorphonuclear neutrophil (PMNs), and rate of culture positivity. Secondary analysis included time elapsed from aspiration to surgery. Results: Of the 126 patients with septic joints included, nearly two-thirds (n = 80 [63.5%]) received antibiotics before joint aspiration. The synovial fluid WBC count, percentage of PMNs, and rate of culture positivity were significantly lower in patients who received preaspiration antibiotics than in those who did not (mean WBC count, 51 379.1/µL [standard deviation, 52 576.3/µL] vs 92 162.7/µL [59 330.6/µL], respectively [P < .001]; PMN percentage, 83.6% [20.5%] vs 91.9% [6.0%; P = .01]; and culture positivity, 32.5% vs 59.1% [P = .008]). Multivariable analyses revealed that these associations remained after controlling for potential confounders (change in PMNs, -42 784.60/µL [95% confidence interval, -65 355/µL to -20 213.90/µL [P < .001]; change in PMNs, -7.8% [-13.7% to -1.8%] [P = .01]; odds ratio, 0.39 [.18-.87; P = .02). Patients with a synovial fluid WBC count ≤50 000/µL experienced significant delay in time from joint aspiration to operative intervention (mean [standard deviation], 10.5 [11.3] vs 17.9 [17.2] hours; P = .02). Conclusions: The administration of antibiotics before joint aspiration for suspected septic arthritis appears to decrease the synovial fluid WBC count, the percentage of PMNs, and the rate of culture positivity. Efforts to limit antibiotic administration before joint aspiration are important to minimize diagnostic dilemmas and circumvent treatment delays.

Racial differences in testing for infectious diseases: An analysis of jail intake data.

HIV and hepatitis C virus (HCV) testing for all people in jail is recommended by the CDC. In the community, there are barriers to HIV and HCV testing for minoritized people. We examined the relationship between race and infectious diseases (HIV, HCV, syphilis) testing in one Massachusetts jail, Middlesex House of Corrections (MHOC). This is a retrospective analysis of people incarcerated at MHOC who opted-in to infectious diseases testing between 2016-2020. Variables of interest were race/ethnicity, self-identified history of psychiatric illness, and ever having experienced restrictive housing. Twenty-three percent (1,688/8,467) of people who were incarcerated requested testing at intake. Of those, only 38% received testing. Black non-Hispanic (25%) and Hispanic people (30%) were more likely to request testing than white people (19%). Hispanic people (16%, AOR 1.69(1.24-2.29) were more likely to receive a test result compared to their white non-Hispanic (8%, AOR 1.54(1.10-2.15)) counterparts. Black non-Hispanic and Hispanic people were more likely to opt-in to and complete infectious disease testing than white people. These findings could be related to racial disparities in access to care in the community. Additionally, just over one-third of people who requested testing received it, underscoring that there is room for improvement in ensuring testing is completed. We hope our collaborative efforts with jail professionals can encourage other cross-disciplinary investigations.

The Impact of Incarceration on Readmissions Among Patients With Inflammatory Bowel Disease Hospitalized at a Community Hospital.

Background and Aims: Individuals who are incarcerated often have limited access to first-line treatment and comprehensive health care. In this study, we aimed to compare the frequency of readmissions among patients with inflammatory bowel disease (IBD) receiving care at a community hospital who were and were not incarcerated at the time of hospitalization. Methods: We analyzed records from Lemuel Shattuck Hospital for all patients admitted between January 1, 2011, and December 31, 2019. Patients with IBD were identified using International Classification of Diseases codes. The primary outcome was all-cause readmission at 1 year following an IBD-related admission. Secondary outcomes were (1) all-cause readmission at 30 days, (2) IBD-related readmission at 30 days, and (3) IBD-related readmission at 1 year. Our indicator of interest was incarceration. Multivariable logistic regression models were built to describe predictors of all-cause readmissions at 1 year. Results: Among the 6511 individuals hospitalized at Lemuel Shattuck Hospital between 2011 and 2019, 90 individuals (1.4%) had International Classification of Diseases codes for IBD, either ulcerative colitis (n = 44) and/or Crohn's disease (n = 39). Half (n = 46) of patients with IBD were incarcerated during hospital admission. Individuals who were incarcerated had a higher rate of all-cause readmissions at 1 year than those who were not incarcerated at the time of hospitalization (76.0% vs 41.5%, P = .005). Multivariable analysis showed patients who were incarcerated had 3.98 (95% confidence interval: 1.39-12.78) increased odds of all-cause readmission within 1 year. Conclusion: Our results suggest individuals with IBD who are incarcerated may experience worse health outcomes than individuals who are not incarcerated, adding to a body of literature documenting the negative impact of incarceration on health.
