ABSTRACT

BACKGROUND: Patients discharged against medical advice do not receive adequate treatment and have a greater risk of readmission. This study assessed the rate of discharges against medical advice following assault-related penetrating trauma, with secondary aims to evaluate long term pre/post-injury hospitalizations and mortality. METHODS: Adult assault-related penetrating injuries admitted to a Level 1 Trauma Center were identified in the prospectively maintained database. Chart review was conducted for hospitalizations ± 5 years from index injury and statewide mortality data was used to identify deaths outside of hospital care. RESULTS: Out of a total of 1,744 assault-related penetrated injuries, 3.2% (52/1630) of survivors discharged against medical advice. Reasons for discharge against medical advice included: unknown (38%), home/child/family/pets (25%), unhappy with care/restrictions (23%), and work/money/other (13%). Post-discharge mortality did not differ between routine (6.5%) and against medical advice discharge (3.9%). Against medical advice and routine discharge had similar rates of any hospitalization (38.5 v 28.2%) and trauma hospitalization in prior 5-years (35 v 36%). However, significantly more against medical advice discharges had prior hospitalizations involving drug or alcohol abuse (65 v 38%), but not mental health diagnosis (55 v 55%). Significantly more against medical advice discharges have post-injury hospitalizations compared to routine discharges (48 vs 26.5%); however, include similar rates of repeat traumatic injury (36 v 32%). CONCLUSIONS: Those with against medical advice discharges were significantly more likely to have prior hospitalizations involving drug or alcohol abuse and significantly higher rates of post-injury hospitalizations. However, we did not see an increase in repeat traumatic injury or post-discharge mortality in those with against medical advice discharges when compared to those with routine discharges.

ABSTRACT

COVID-19 disproportionately affects people experiencing homelessness or incarceration. While homelessness or incarceration alone may not impact vaccine effectiveness, medical comorbidities along with social conditions associated with homelessness or incarceration may impact estimated vaccine effectiveness. COVID-19 vaccines reduce rates of hospitalization and death; vaccine effectiveness (VE) against severe outcomes in people experiencing homelessness or incarceration is unknown. We conducted a retrospective, observational cohort study evaluating COVID-19 vaccine VE against SARS-CoV-2 related hospitalization (positive SARS-CoV-2 molecular test same week or within 3 weeks prior to hospital admission) among patients who had experienced homelessness or incarceration. We utilized data from 8 health systems in the Minnesota Electronic Health Record Consortium linked to data from Minnesota's immunization information system, Homeless Management Information System, and Department of Corrections. We included patients 18 years and older with a history of experiencing homelessness or incarceration. VE and 95% Confidence Intervals (CI) against SARS-CoV-2 hospitalization were estimated for primary series and one booster dose from Cox proportional hazard models as 100*(1-Hazard Ratio) during August 26, 2021, through October 8, 2022 adjusting for patient age, sex, comorbid medical conditions, and race/ethnicity. We included 80,051 individuals who had experienced homelessness or incarceration. Adjusted VE was 52% (95% CI, 41-60%) among those 22 weeks or more since their primary series, 66% (95% CI, 53-75%) among those less than 22 weeks since their primary series, and 69% (95% CI: 60-76%) among those with one booster. VE estimates were consistently lower during the Omicron predominance period compared with the combined Omicron and Delta periods. Despite higher exposure risk, COVID-19 vaccines provided good effectiveness against SARS-CoV-2 related hospitalizations in persons who have experienced homelessness or incarceration.

ABSTRACT

The drug overdose epidemic in the US necessitates detailed and timely data to inform public health responses. In this article we describe how an electronic health record (EHR) data-sharing collaboration across health systems in Minnesota that was developed in response to the COVID-19 pandemic was adapted to monitor trends in substance use-related hospital and emergency department (ED) visits. We found large increases in methamphetamine- and opioid-involved hospital and ED visits. Throughout the study period, Native American, Black, and multiple-race people experienced the highest rates of drug-involved hospital and ED visits. Monitoring drug-involved health care use through EHR data has the potential to help public health officials detect trends in near real time before mortality spikes and may also inform early intervention. The use of EHR data also allows for detailed monitoring of the impact of the drug overdose epidemic across racial and ethnic groups.

ABSTRACT

We used data from a statewide public health-health system collaboration to describe trends in COVID-19 vaccination rates by racial and ethnic groups among people experiencing homelessness or incarceration in Minnesota. Vaccination completion rates among the general population and people incarcerated in state prisons were substantially higher than those among people experiencing homelessness or jail incarceration.

ABSTRACT

Importance: COVID-19 vaccines are effective, but inequities in vaccine administration and waning immunity may limit vaccine effectiveness. Objectives: To report statewide trends in vaccine administration and vaccine effectiveness in Minnesota. Design, Setting, and Participants: This cohort study used COVID-19 vaccine data from the Minnesota Immunization Information Connection from October 25, 2020, through October 30, 2021 that were linked with electronic health record (EHR) data from health systems collaborating as part of the Minnesota EHR Consortium (MNEHRC). Participants included individuals who were seen at a participating health system in Minnesota. Exposures: Individuals were considered fully vaccinated in the second week after receipt of a second dose of a BNT162b2 or mRNA-1273 vaccine or a single dose of an Ad26.COV.2.S vaccine. Main Outcomes and Measures: A completed vaccination series and vaccine breakthrough, defined as either a positive SARS-CoV-2 polymerase chain reaction (PCR) test or a hospital admission the same week or within the 3 weeks following a positive SARS-CoV-2 PCR test. A test-negative design and incident rate ratio were used to evaluate COVID-19 vaccine effectiveness separately for the BNT162b2, mRNA-1273, and Ad26.COV.2.S vaccines. Rurality and social vulnerability index were assessed at the area level. Results: This study included 4 431 190 unique individuals at participating health systems, and 3 013 704 (68%) of the individuals were fully vaccinated. Vaccination rates were lowest among Minnesotans who identified as Hispanic (116 422 of 217 019 [54%]), multiracial (30 066 of 57 412 [52%]), American Indian or Alaska Native (22 190 of 41 437 [54%]), and Black or African American (158 860 of 326 595 [49%]) compared with Minnesotans who identified as Asian or Pacific Islander (159 999 of 210 994 [76%]) or White (2 402 928 of 3 391 747 [71%]). Among individuals aged 19 to 64 years, vaccination rates were lower in rural areas (196 479 of 308 047 [64%]) compared with urban areas (151 541 of 1 951 265 [77%]) and areas with high social vulnerability (544 433 of 774 952 [70%]) compared with areas with low social vulnerability (571 613 of 724 369 [79%]). In the 9 weeks ending October 30, 2021, vaccine effectiveness as assessed by a test-negative design was 33% (95% CI, 30%-37%) for Ad26.COV.2.S; 53% (95% CI, 52%-54%) for BNT162b2; and 66% (95% CI, 65%-67%) for mRNA-1273. For SARS-CoV-2-related hospitalizations, vaccine effectiveness in the 9 weeks ending October 30, 2021, was 78% (95% CI, 75%-81%) for Ad26.COV.2.S; 81% (95% CI, 79%-82%) for BNT162b2; and 81% (95% CI, 79%-82%) for mRNA-1273. Conclusions and Relevance: This cohort study of data from a Minnesota statewide consortium suggests disparities in vaccine administration and effectiveness. Vaccine effectiveness against infection was lower for Ad26.COV.2.S and BNT162b2 but was associated with protection against SARS-CoV-2-related hospitalizations despite the increased prevalence of the Delta variant in Minnesota.

ABSTRACT

OBJECTIVE: Robust disease and syndromic surveillance tools are underdeveloped in the United States, as evidenced by limitations and heterogeneity in sociodemographic data collection throughout the COVID-19 pandemic. To monitor the COVID-19 pandemic in Minnesota, we developed a federated data network in March 2020 using electronic health record (EHR) data from 8 multispecialty health systems. MATERIALS AND METHODS: In this serial cross-sectional study, we examined patients of all ages who received a COVID-19 polymerase chain reaction test, had symptoms of a viral illness, or received an influenza test from January 3, 2016, through November 7, 2020. We evaluated COVID-19 testing rates among patients with symptoms of viral illness and percentage positivity among all patients tested, in aggregate and by zip code. We stratified results by patient and area-level characteristics. RESULTS: Cumulative COVID-19 positivity rates were similar for people aged 12-64 years (range, 15.1%-17.6%) but lower for adults aged ≥65 years (range, 9.3%-10.7%). We found notable racial and ethnic disparities in positivity rates early in the pandemic, whereas COVID-19 positivity was similarly elevated across most racial and ethnic groups by the end of 2020. Positivity rates remained substantially higher among Hispanic patients compared with other racial and ethnic groups throughout the study period. We found similar trends across area-level income and rurality, with disparities early in the pandemic converging over time. PRACTICE IMPLICATIONS: We rapidly developed a distributed data network across Minnesota to monitor the COVID-19 pandemic. Our findings highlight the utility of using EHR data to monitor the current pandemic as well as future public health priorities. Building partnerships with public health agencies can help ensure data streams are flexible and tailored to meet the changing needs of decision makers.

ABSTRACT

OBJECTIVES: To estimate the health characteristics and racial/ethnic health disparities among a probation cohort in Hennepin County. We hypothesised the probation population would have higher health needs compared with the general population as well as significant racial/ethnic health disparities. DESIGN: Cross-sectional study using linked administrative records. PARTICIPANTS: Of 7992 eligible individuals, 5873 met inclusion criteria of 6 or more months of eligibility for a full-benefit Minnesota healthcare plan. SETTING: Probation system in Hennepin County in 2016. OUTCOMES: We compared health condition prevalence among our probation cohort with survey data from the general population and analysed by race/ethnicity. We also measured sociodemographic characteristics, including the use of safety-net services. RESULTS: Individuals were predominantly male (80.5%), young (mean age: 35.5 years), and disproportionately black or African American (52.9%). A majority of individuals enrolled in Medicaid were eligible via Medicaid expansion (65.9%). Compared with the general population, individuals on probation had higher rates of substance use disorders (66.5% vs 8.1%), mental illness (55.3% vs 14.4%) and many physical conditions (eg, asthma: 17.0% vs 12.5%, chronic kidney disease: 5.8% vs 0.2%). White individuals on probation were significantly more likely than black or African American individuals to have a diagnosed substance use disorder (71.6% vs 62.0%) or mental health disorder (64.9% vs 48.5%), but fewer chronic physical health conditions (average: 0.52 vs 0.73 chronic physical conditions). CONCLUSIONS: Individuals on probation have high health needs, which vary substantially by race/ethnicity. Without attention to this variation, interventions to address health conditions in this population could worsen racial/ethnic disparities.

ABSTRACT

OBJECTIVE: The heterogeneous implementation and uptake of nonpharmaceutical interventions (NPIs) during the coronavirus disease 2019 (COVID-19) pandemic amplified the need for locally responsive disease surveillance mechanisms. Using data from a newly developed statewide electronic health record (EHR) consortium in Minnesota, we sought to characterize trends in pediatric viral symptoms, influenza testing, and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) testing. METHODS: We conducted a serial cross-sectional analysis of EHR data from 1/1/2017 to 7/30/2021 across 8 large health systems in Minnesota. We included patients ≤18 years of age with any SARS-CoV-2 test, influenza test, or documented diagnostic code which met our viral symptom definition. We plotted week-by-week trends in viral symptoms, SARS-CoV-2 and influenza testing, and test positivity, stratified between children (0-11 years) and adolescents (12-18 years). RESULTS: We identified 1,079,924 patients ≤18 years of age with viral symptoms or testing; 880,669 (81.5%) were children ≤11 years. Influenza testing and influenza test positivity remained well below historical averages from March 2020 through mid-May 2021. Peaks in viral symptoms during this time were concomitant with peaks in SARS-CoV-2 testing and test positivity, whereas influenza testing and test positivity remained stagnant. Influenza test positivity rates increased substantively among children from May through July 2021. CONCLUSIONS: Viral illness and influenza testing among pediatric patients were below historical averages throughout the COVID-19 pandemic. Ongoing increases in influenza test positivity may merit clinical and public health awareness and intervention. Future NPI policies can be better targeted with insights from collaborative EHR-based surveillance, which enhances real-time, locally sensitive measurement of disease outbreaks.

ABSTRACT

Hennepin Health, a Medicaid accountable care organization, began serving early expansion enrollees (very low-income childless adults) in 2012. It uses an integrated care model to address social and behavioral needs. We compared health care utilization in Hennepin Health with other Medicaid managed care in the same area from 2012 to 2014, controlling for demographics, chronic conditions, and enrollment patterns. Homelessness and substance use were higher in Hennepin Health. Overall adjusted results showed Hennepin Health had 52% more emergency department visits and 11% more primary care visits than comparators. Over time, modeling a 6-month exposure to Hennepin Health, emergency department and primary care visits decreased and dental visits increased; hospitalizations decreased nonsignificantly but increased among comparators. Subgroup analysis of high utilizers showed lower hospitalizations in Hennepin Health. Integrated, accountable care under Medicaid expansion showed some desirable trends and subgroup benefits, but overall did not reduce acute health care utilization versus other managed care.

ABSTRACT

BACKGROUND: The expansion of Medicaid as part of the Affordable Care Act opened new opportunities to provide health coverage to low-income adults who may be involved in other public sectors. OBJECTIVE: The main objective of this study was to describe cross-sector utilization patterns among urban Medicaid expansion enrollees. RESEARCH DESIGN: We merged data from 4 public sectors (health care, human services, housing, and criminal justice) for 98,282 Medicaid expansion enrollees in Hennepin County, MN. We fit a latent class model to indicators of cross-sector involvement. MEASURES: Indicator variables described involvement levels within each sector from March 2011 through December 2014. Demographic and chronic condition indicators were included post hoc to characterize classes. RESULTS: We found 6 archetypes of cross-sector involvement: The "Low Contact" class (33.9%) had little involvement in any public sector; "Primary Care" (26.3%) had moderate, stable health care utilization; "Health and Human Services" (15.3%) had high rates of health care and cash assistance utilization; "Minimal Criminal History" (11.0%) had less serious criminal justice involvement; "Cross-sector" (7.8%) had elevated emergency department use, involvement in all 4 sectors, and the highest prevalence of behavioral health conditions; "Extensive Criminal History" (5.7%) had serious criminal justice involvement. The 3 most expensive classes (Health and Human Services, Cross-sector, and Extensive Criminal History) had the highest rates of behavioral health conditions. Together, they comprised 29% of enrollees and 70% of total public costs. CONCLUSIONS: Medicaid expansion enrollees with behavioral health conditions deserve focus due to the high cost-reduction potential across public sectors. Cross-sector collaboration is a plausible path to reduce costs and improve outcomes.

ABSTRACT

Childless adults in the Medicaid expansion population have complex social and behavioral needs. This study compared the cross-sector involvement of Medicaid expansion enrollees who were high health care utilizers to that of other expansion enrollees in Hennepin County, Minnesota. We examined forty-six months of annualized utilization and cost data for expansion-eligible residents with at least twelve months of enrollment (N = 70,134) across health care, housing, criminal justice, and human service sectors. High health care utilizers, approximately 7 percent of our sample, were disproportionately American Indian, younger, and significantly more likely than other expansion enrollees to have mental health (88.1 percent versus 48.0 percent) or substance use diagnoses (79.2 percent versus 29.6 percent). Total cross-sector public spending was nearly four times higher for high health care users ($25,337 versus $6,786), and their non-health care expenses were 2.4 times higher ($7,476 versus $3,108). High levels of cross-sector service use suggest that there are opportunities for collaboration that may result in cost savings across sectors.

ABSTRACT

OBJECTIVE: To design and test the validity of a method to identify homelessness among Medicaid enrollees using mailing address data. DATA SOURCES/STUDY SETTING: Enrollment and claims data on Medicaid expansion enrollees in Hennepin and Ramsey counties who also provided self-reported information on their current housing situation in a psychosocial needs assessment. STUDY DESIGN: Construction of address-based indicators and comparison with self-report data. PRINCIPAL FINDINGS: Among 1,677 enrollees, 427 (25 percent) self-reported homelessness, of whom 328 (77 percent) had at least one positive address indicator. Depending on the type of addresses included in the indicator, sensitivity to detect self-reported homelessness ranged from 30 to 76 percent and specificity from 79 to 97 percent. CONCLUSIONS: An address-based indicator can identify a large proportion of Medicaid enrollees who are experiencing homelessness. This approach may be of interest to researchers, states, and health systems attempting to identify homeless populations.
