Abstract
People experiencing homelessness in crisis have unique structural vulnerabilities and social needs, most importantly lack of housing. Ideal crisis services for people experiencing homelessness must safeguard against criminalization and displacement during periods of crisis, prioritize equity, and provide housing interventions alongside mental health treatment at every stage in the crisis continuum. By outlining how to tailor crisis system financing and accountability, service component and capacity, and clinical best practices, the authors aim to provide hope and guidance for communities aiming to create an ideal crisis system for people experiencing homelessness.

J Prim Care Community Health 2024; 15:21501319241255917. [PMID: 38761365 PMCID: PMC11102682 DOI: 10.1177/21501319241255917] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2024] [Revised: 04/29/2024] [Accepted: 05/01/2024] [Indexed: 05/20/2024] Open
Abstract
INTRODUCTION/OBJECTIVES Social determinants of health (SDoH) screening and intervention in pediatric primary care depends upon caregiver disclosure of adverse household or social conditions and thus may be influenced by perceived bias or stigma. This paper examines to what extent parents' experience of their child's medical home is associated with their perceptions of a practice-based social needs intervention. METHODS We conducted a cohort study of data reported by 73 parents of children obtaining care in a medical home with an embedded SDoH navigation program. Using survey data collected in October 2021 and October 2022, we calculated descriptive statistics and non-parametric bivariate analyses of the association between engagement with the SDoH navigation program and parent-reported social needs, stress, and perception of care quality as measured by the Person-Centered Primary Care Measure (PCPCM). RESULTS Initial ratings of care quality were high (mean baseline PCPCM score = 3.63) and remained high on second interview (mean change in PCPCM score = -0.04, 95%CI -0.16, 0.09, P = .58) despite significant reductions in parents' ratings of access to care over time. Parents reported substantial stress, unmet social needs, and unmet healthcare needs, with 41 families (56%) ever using the practice-based SDoH program, including 16 (22%) who were new users in 2022. There was no association observed between PCPCM score and parent stress, unmet social needs, or use of SDoH services. CONCLUSIONS Parents' perceptions of care delivered in their child's medical home appears to be stable on repeat measurement, and independent of family context or interactions with social needs navigation services offered in the practice.

PLoS One 2023; 18:e0293070. [PMID: 37856507 PMCID: PMC10586599 DOI: 10.1371/journal.pone.0293070] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2023] [Accepted: 10/04/2023] [Indexed: 10/21/2023] Open
Abstract
Meningococcal disease is a serious but rare disease in the United States. Prior publications suggest incidence differs among privately vs publicly-insured persons, and that incidence is higher among persons experiencing homelessness (PEH) than persons not known to be experiencing homelessness (non-PEH). Using insurance claims data for persons aged <1 to 64 years, we calculated meningococcal disease incidence among a population with employer-sponsored commercial insurance and persons enrolled in state Medicaid programs nationwide. We also examined meningococcal disease incidence by PEH status in Medicaid data. From 2016 through 2019, persons who met our study inclusion criteria contributed a total of 84,460,548 person-years (PYs) to our analysis of commercial insurance data and 253,496,622 PYs to our analysis of Medicaid data. Incidence was higher among persons enrolled in Medicaid (0.12 cases per 100,000 PYs) than persons with commercial insurance (0.06 cases per 100,000 PYs). Incidence was 3.17 cases per 100,000 PYs among PEH in Medicaid, 27 times higher than among non-PEH in Medicaid. Understanding the underlying drivers of the higher meningococcal disease incidence among PEH and persons enrolled in Medicaid may inform prevention strategies for populations experiencing a higher burden of disease.

Trends, Characteristics, and Maternal Morbidity Associated With Unhoused Status in Pregnancy. JAMA Netw Open 2023; 6:e2326352. [PMID: 37523185 PMCID: PMC10391303 DOI: 10.1001/jamanetworkopen.2023.26352] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2023] [Accepted: 06/18/2023] [Indexed: 08/01/2023] Open
Abstract
Importance Unhoused status is a substantial problem in the US. Pregnancy characteristics and maternal outcomes of individuals experiencing homelessness are currently under active investigation to optimize health outcomes for this population. Objective To assess the trends, characteristics, and maternal outcomes associated with unhoused status in pregnancy. Design, Setting, and Participants This cross-sectional study analyzed data from the Healthcare Cost and Utilization Project National (Nationwide) Inpatient Sample. The study population included hospitalizations for vaginal and cesarean deliveries from January 1, 2016, to December 31, 2020. Unhoused status of these patients was identified from use of International Statistical Classification of Diseases, Tenth Revision, Clinical Modification code Z59.0. Statistical analysis was conducted from December 2022 to June 2023. Main Outcomes and Measures Primary outcomes were (1) temporal trends; (2) patient and pregnancy characteristics associated with unhoused status, which were assessed with a multivariable logistic regression model; (3) delivery outcomes, including severe maternal morbidity (SMM) and mortality at delivery, which used the Centers for Disease Control and Prevention definition for SMM indicators and were assessed with a propensity score-adjusted model; and (4) choice of long-acting reversible contraception method and surgical sterilization at delivery. Results A total of 18 076 440 hospital deliveries were included, of which 18 970 involved pregnant patients who were experiencing homelessness at the time of delivery, for a prevalence rate of 104.9 per 100 000 hospital deliveries. These patients had a median (IQR) age of 29 (25-33) years. The prevalence of unhoused patients increased by 72.1% over a 5-year period from 76.1 in 2016 to 131.0 in 2020 per 100 000 deliveries (P for trend < .001). This association remained independent in multivariable analysis. In addition, (1) substance use disorder (tobacco, illicit drugs, and alcohol use disorder), (2) mental health conditions (schizophrenia, bipolar, depressive, and anxiety disorders, including suicidal ideation and past suicide attempt), (3) infectious diseases (hepatitis, gonorrhea, syphilis, herpes, and COVID-19), (4) patient characteristics (Black and Native American race and ethnicity, younger and older age, low or unknown household income, obesity, pregestational hypertension, pregestational diabetes, and asthma), and (5) pregnancy characteristics (prior uterine scar, excess weight gain during pregnancy, and preeclampsia) were associated with unhoused status in pregnancy. Unhoused status was associated with extreme preterm delivery (<28-week gestation: 34.3 vs 10.8 per 1000 deliveries; adjusted odds ratio [AOR], 2.76 [95% CI, 2.55-2.99]); SMM at in-hospital delivery (any morbidity: 53.8 vs 17.7 per 1000 deliveries; AOR, 2.30 [95% CI, 2.15-2.45]); and in-hospital mortality (0.8 vs <0.1 per 1000 deliveries; AOR, 10.17 [95% CI, 6.10-16.94]), including case fatality risk after SMM (1.5% vs 0.3%; AOR, 4.46 [95% CI, 2.67-7.45]). Individual morbidity indicators associated with unhoused status included cardiac arrest (AOR, 12.43; 95% CI, 8.66-17.85), cardiac rhythm conversion (AOR, 6.62; 95% CI, 3.98-11.01), ventilation (AOR, 6.24; 95% CI, 5.03-7.74), and sepsis (AOR, 5.37; 95% CI, 4.53-6.36). Conclusions and Relevance Results of this national cross-sectional study suggest that unhoused status in pregnancy gradually increased in the US during the 5-year study period and that pregnant patients with unhoused status were a high-risk pregnancy group.

A feasibility and acceptability study of screening the parents/guardians of pediatric dental patients for the social determinants of health. Pilot Feasibility Stud 2023; 9:36. [PMID: 36895054 PMCID: PMC9996555 DOI: 10.1186/s40814-023-01269-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2022] [Accepted: 02/27/2023] [Indexed: 03/11/2023] Open
Abstract
BACKGROUND The social determinants of health (SDOH) are the conditions in which people are born, grow, work, live, and age. Lack of SDOH training of dental providers on SDOH may result in suboptimal care provided to pediatric dental patients and their families. The purpose of this pilot study is to report the feasibility and acceptability of SDOH screening and referral by pediatric dentistry residents and faculty in the dental clinics of Family Health Centers at NYU Langone (FHC), a Federally Qualified Health Center (FQHC) network in Brooklyn, NY, USA. METHODS Guided by the Implementation Outcomes Framework, 15 pediatric dentists and 40 pediatric dental patient-parent/guardian dyads who visited FHC in 2020-2021 for recall or treatment appointments participated in this study. The a priori feasibility and acceptability criteria for these outcomes were that after completing the Parent Adversity Scale (a validated SDOH screening tool), ≥ 80% of the participating parents/guardians would feel comfortable completing SDOH screening and referral at the dental clinic (acceptable), and ≥ 80% of the participating parents/guardians who endorsed SDOH needs would be successfully referred to an assigned counselor at the Family Support Center (feasible). RESULTS The most prevalent SDOH needs endorsed were worried within the past year that food would run out before had money to buy more (45.0%) and would like classes to learn English, read better, or obtain a high school degree (45.0%). Post-intervention, 83.9% of the participating parents/guardians who expressed an SDOH need were successfully referred to an assigned counselor at the Family Support Center for follow-up, and 95.0% of the participating parents/guardians felt comfortable completing the questionnaire at the dental clinic, surpassing the a priori feasibility and acceptability criteria, respectively. Furthermore, while most (80.0%) of the participating dental providers reported being trained in SDOH, only one-third (33.3%) usually or always assess SDOH for their pediatric dental patients, and most (53.8%) felt minimally comfortable discussing challenges faced by pediatric dental patient families and referring patients to resources in the community. CONCLUSIONS This study provides novel evidence of the feasibility and acceptability of SDOH screening and referral by dentists in the pediatric dental clinics of an FQHC network.

Abstract
IMPORTANCE Housing instability and other social determinants of health are increasingly being documented by clinicians. The most common reasons for hospitalization among patients with coded housing instability, however, are not well understood. OBJECTIVE To compare the most common reasons for hospitalization among patients with and without coded housing instability. DESIGN, SETTING, AND PARTICIPANTS This cross-sectional, retrospective study identified hospitalizations of patients between age 18 and 99 years using the 2017 to 2019 National Inpatient Sample. Data were analyzed from May to September 2022. EXPOSURES Housing instability was operationalized using 5 International Classification of Diseases, 10th Revision, Social Determinants of Health Z-Codes addressing problems related to housing: homelessness; inadequate housing; discord with neighbors, lodgers, and landlords; residential institution problems; and other related problems. MAIN OUTCOMES AND MEASURES The primary outcome of interest was reason for inpatient admission. Bivariate comparisons of patient characteristics, primary diagnoses, length of stay, and hospitalization costs among patients with and without coded housing instability were performed. RESULTS Among the 87 348 604 hospitalizations analyzed, the mean (SD) age was 58 (20) years and patients were more likely to be women (50 174 117 [57.4%]) and White (58 763 014 [67.3%]). Housing instability was coded for 945 090 hospitalizations. Hospitalized patients with housing instability, compared with those without instability, were more likely to be men (668 255 patients with coded instability [70.7%] vs 36 506 229 patients without [42.3%]; P < .001), younger (mean [SD] age 45.5 [14.0] vs 58.4 [20.2] years), Black (235 355 patients [24.9%] vs 12 929 158 patients [15.0%]), Medicaid beneficiaries (521 555 patients [55.2%] vs 15 541 175 patients [18.0%]), uninsured (117 375 patients [12.4%] vs 3 476 841 patients [4.0%]), and discharged against medical advice (28 890 patients [8.4%] vs 451 855 patients [1.6%]). The most common reason for hospitalization among patients with coded housing instability was mental, behavioral, and neurodevelopmental disorders (475 575 patients [50.3%]), which cost a total of $3.5 billion. Other common reasons included injury (69 270 patients [7.3%]) and circulatory system diseases (64 700 patients [6.8%]). Coded housing instability was also significantly associated with longer mean (SD) hospital stays (6.7 [.06] vs 4.8 [.01] days) and a cost of $9.3 billion. Hospitalized patients with housing instability had 18.6 times greater odds of having a primary diagnosis of mental, behavioral, and neurodevelopmental disorders (475 575 patients [50.3%] vs 4 470 675 patients [5.2%]; odds ratio, 18.56; 95% CI, 17.86 to 19.29). CONCLUSIONS AND RELEVANCE In this cross-sectional study, hospitalizations among patients with coded housing instability had higher admission rates for mental, behavioral, and neurodevelopmental disorders, longer stays, and increased costs. Findings suggest that efforts to improve housing instability, mental and behavioral health, and inpatient hospital utilization across multiple sectors may find areas for synergistic collaboration.

Abstract
Homelessness poses a direct threat to public health in the US as many individuals face debilitating health outcomes and barriers to adequate health care. Access to STI care for the homeless Medicaid population of USA has not been well-studied using administrative claims data. Our study aims to compare health services utilization, STI screening and diagnoses among people experiencing homelessness (PEH) vs. those who are non-PEH using ICD10 codes. We used 2019 MarketScan Medicaid claims data to analyze men and women aged 15-44 years with a diagnosis code for PEH (Z59.0), non-PEH (without Z59.0) and assessed their emergency department and outpatient visits and STI/HIV diagnoses and screening rates. We identified 5135 PEH men and 3571 PEH women among 1.3 million men and 2.1 million women in the 2019 US Medicaid database. PEH patients were more likely to have ED visits (94.80% vs 33.04%) and ≥ 20 outpatient clinic visits (60.29% vs 16.16%) than non-PEH patients in 2019. Higher diagnoses were observed for syphilis 1.57% (CI 1.32-1.86) vs 0.11% (CI 0.11-0.11), HIV 3.93% (CI 3.53-4.36) vs 0.41% (CI 0.41-0.42), chlamydia 1.94% (CI 1.66-2.25) vs 0.85% (CI 0.84-0.86) and gonorrhea 1.26% (CI 1.04-1.52) vs. 0.33% (CI 0.33-0.34) (p < 0.0001) among PEH compared to non-PEH. Among PEH, higher STI/HIV diagnoses rates indicate an increase in STI burden and suboptimal STI testing indicates an underutilization of STI services despite having a higher percentage of health care visits compared to non-PEH patients. Focused STI/HIV interventions are needed to address health care needs of PEH patients.
