Fatal and non-fatal civilian injuries sustained during law enforcement-reported encounters in California, 2016-2021.

BACKGROUND: In 2015, California passed AB 71 to create a state-wide Use of Force Incident Reporting Database (URSUS) to tabulate law enforcement-reported encounters that resulted in serious bodily injury, death or discharge of a firearm. We use these data to analyse encounters that resulted in fatal and non-fatal civilian injuries in California between 2016 and 2021. METHODS: We performed a retrospective review of URSUS from January 2016 to December 2021. The main outcomes were the number of law enforcement encounters that involved civilian serious bodily injury or death and encounter-level characteristics. RESULTS: URSUS recorded 3677 incidents between 2016 and 2021 resulting in 942 civilian fatalities and 2735 instances of serious civilian injuries. Injury rates were highest for civilians who identified as Hispanic (1.80 injuries per 100 000 population) or black (5.17 injuries per 100 000 population). Injuries involving a firearm were usually fatal (58.9% fatality rate; 1471 injuries), while non-firearm incidents were more likely to result in serious injuries (4.2% fatality rate; 2929 injuries). We did not find statistically significant trends in rates of civilian injuries per 100 000 population. CONCLUSION: Rates of law enforcement-related injuries were highest for Hispanic and black civilians in California between 2016 and 2021 and firearm-related injuries were overwhelmingly fatal. The URSUS database represents an important effort by law enforcement agencies to collect information on injuries and fatalities resulting from law enforcement encounters. Given similar databases exist in fewer than half of states, additional legislative efforts are needed to improve systematic national data collection on these encounters.

How do ED patients with criminal justice contact compare with other ED users? A retrospective analysis of ED visits in California.

OBJECTIVE: To assess the patterns of emergency department (ED) utilisation among those with and without criminal justice contact in California in 2014, comparing variation in ED use, visit frequency, diagnoses and insurance coverage. DESIGN: Retrospective, cross-sectional study. SETTING: Analyses included ED visits to all licensed hospitals in California using statewide data on all ED encounters in 2014. PARTICIPANTS: Study participants included 3 757 870 non-elderly adult ED patients who made at least one ED visit in 2014. PRIMARY AND SECONDARY OUTCOME MEASURES: We assessed the patterns and characteristics of ED visits among those with criminal justice contact-patients who were either admitted to or discharged from the ED by a correctional institution-with patients who did not have criminal justice contact recorded during an ED visit. RESULTS: ED patients with criminal justice contact had higher proportions of frequent ED users (27.2% vs 9.4%), were at higher risk of an ED visit resulting in hospitalisation (26.6% vs 15.2%) and had higher prevalence of mental health conditions (52.8% vs 30.4%) compared with patients with no criminal justice contact recorded during an ED visit. Of the top 10, four primary diagnoses among patients with criminal justice contact were related to behavioural health conditions, accounting for 19.0% of all primary diagnoses in this population. In contrast, behavioural health conditions were absent from the top 10 primary diagnoses in ED patients with no observed criminal justice contact. Despite a high burden of disease, a lack of health insurance coverage was more common among those with criminal justice contact than those without (41.3% vs 14.1%). CONCLUSIONS: Given that a large proportion of ED patients with criminal justice contact are frequent users with considerable mental health conditions, current efforts in California's Medicaid programme to identify individuals in need of coordinated services could reduce costly ED utilisation among this group.

Frequent Emergency Department Users: A Statewide Comparison Before And After Affordable Care Act Implementation.

Frequent emergency department (ED) use often serves as a marker for poor access to non-ED ambulatory care. Policy makers and providers hoped that by expanding coverage, the Affordable Care Act (ACA) would curtail frequent ED use. We used data from California's Office of Statewide Health Planning and Development to compare the characteristics of frequent ED users among nonelderly adults in California before and after implementation of several major coverage expansion provisions in the ACA. Frequent users-patients with four or more annual ED visits-accounted for 7.9 percent of ED patients before and 8.5 percent after those provisions were implemented, and they were responsible for 30.7 percent of all visits before and 31.6 percent after. However, after controlling for patient-level characteristics, we found that the odds of being a frequent ED user were significantly lower post ACA for Medicaid-insured patients. Uninsured patients were also less likely to be frequent users post ACA, while privately insured patients experienced little change. The largest predictors of frequent ED use included having a diagnosis of a mental health condition or a substance use disorder. Interventions to address frequent ED use must involve Medicaid managed care plans, given that more than two-thirds of frequent ED users post ACA have Medicaid as their primary coverage source.

Differences between incarcerated and non-incarcerated patients who die in community hospitals highlight the need for palliative care services for seriously ill prisoners in correctional facilities and in community hospitals: A cross-sectional study.

BACKGROUND: Incarcerated populations worldwide are aging dramatically; in the United States, prisoner mortality rates have reached an all-time high. Little is known about the incarcerated patients who die in community hospitals. AIM: Compare incarcerated and non-incarcerated hospital decedents in California. DESIGN: Cross-sectional study. SETTING/PARTICIPANTS: All state hospital decedents ( N = 370,831) from 2009 to 2013, decedent age over time examined with additional data (2001-2013). RESULTS: Overall, 745 incarcerated and 370,086 non-incarcerated individuals died in California hospitals. Incarcerated decedents were more often male (93% vs 51%), Black (19% vs 8%) Latino (27% vs 19%), younger (55 vs 73 years), had shorter hospitalizations (13 vs 16 days), and fewer had an advance care plan (23% vs 36%, p < 0.05). Incarcerated decedents had higher rates of cancer, liver disease, HIV/AIDs, and mental health disorders. Cause of death was disproportionately missing for incarcerated decedents. The average age of incarcerated decedents rose between 2001 and 2013, while it remained stable for others. CONCLUSION: Palliative care services in correctional facilities should accommodate the needs of relatively young patients and those with mental illness. Given the simultaneous growth in the older prisoner population with the rising age of incarcerated hospital decedents, community hospital clinicians should be prepared to care for seriously ill, incarcerated patients. Significant epidemiologic differences between incarcerated and non-incarcerated decedents in this study suggest the importance of examining the differential palliative care needs of incarcerated patients in all communities.

Association of Legal Intervention Injuries With Race and Ethnicity Among Patients Treated in Emergency Departments in California.

Importance: Increased public concern regarding police use of force has coincided with a dearth of available data to uncover the magnitude and trends in injuries, particularly across race or ethnicity. Objective: To examine trends in injury rates, severity, and disparities across black individuals, white individuals, Hispanic individuals, and Asian/Pacific Islander individuals. Design, Setting, and Participants: In this retrospective, cross-sectional study, data collected on every hospital visit in California from January 1, 2005, to September 30, 2015, were used to model trends in rates of legal intervention injuries (n = 92 386) per capita and per arrest for men aged 14 to 64 years, by race or ethnicity. The study also examined descriptive statistics on injury dispositions to assess changes in severity. Analyses were conducted between December 2017 and June 2018. Main Outcomes and Measures: All visits with an external cause of injury code of E970 to E977 were classified as legal intervention injuries. This range of codes includes injuries inflicted by the police or other law-enforcing agents in the course of arresting or attempting to arrest lawbreakers, suppressing disturbances, maintaining order, and other legal action. Results: The study identified a total of 92 386 hospital visits that were the result of legal intervention among males aged 14 to 64 years. Black individuals were at the highest risk of legal intervention injury per capita in 2005 (for black vs white individuals, rate ratio, 2.90; 95% CI, 2.74-3.06), and remained so across the study period. Although rates among Asian/Pacific Islander individuals remained stable, rates in all other groups increased from 2005 to 2009 and then declined from 2009 to 2015, nearly returning to 2005 levels. During the period of increasing rates, the black to white disparity widened by 3% annually (rate ratio, 1.03; 95% CI, 1.01-1.05), then narrowed as rates declined. In contrast, rates of injury per arrest have increased over the past decade, although rates were broadly similar across race or ethnicity. The proportion of injuries involving firearms (ie, shootings by police) declined from 7.0% in 2005 and 2006 to 3.7% in 2014 and 2015. Conclusions and Relevance: States with central repositories for hospital visits offer data sources to illuminate the public health problem of legal intervention injuries, and warrant greater attention to ensure consistent coding for complete capture.

Factors Associated With Emergency Department Use by Patients With and Without Mental Health Diagnoses.

Importance: An association between frequent use of the emergency department (ED) and mental health diagnoses is frequently documented in the literature, but little has been done to more thoroughly understand why mental illness is associated with increased ED use. Objective: To determine which factors were associated with higher ED use in the near future among patients with and without mental health diagnoses. Design, Setting, and Participants: A retrospective case-control study of all patients presenting to the ED in California in 2013 using past ED data to predict future ED use. Data from January 1, 2012, through December 31, 2014, from California's Office of Statewide Health Planning and Development were analyzed. Main Outcomes and Measures: Factors associated with higher ED use in the year following an index visit for patients with vs without a mental health diagnosis. Results: Among the 3 446 338 individuals in the study (accounting for 7 678 706 ED visits), 44.6% (1 537 067) were male; 31.6% (1 089 043) were between the ages of 18 and 30 years, 40.3% (1 338 874) were between the ages of 31 and 50 years, and 28.1% (968 421) were between the ages of 51 and 64 years. The mean (SD) number of ED visits per patient per year was 1.69 (2.56), and 29.1% of patients (1 002 884) had at least 1 mental health diagnosis. Previous hospitalization and high rates of lagged ED visits were associated with higher future ED use. The severity of the mental health diagnosis (mild, moderate, or severe) was associated with increased ED visits (incidence rate ratio [IRR], 1.029; 95% CI, 1.02-1.04 for mild; IRR, 1.121; 95% CI, 1.11-1.13 for moderate; and IRR, 1.226; 95% CI, 1.22-1.24 for severe). Little evidence was found for interaction effects between mental health diagnoses and other diagnoses in predicting increased future ED use. Conclusions and Relevance: Certain classes of mental health diagnoses were associated with higher ED use. The presence of a mental illness diagnosis did not appear to interact with other patient-level factors in a way that meaningfully altered associations with future ED use.

Differences in neonatal mortality among whites and Asian American subgroups: evidence from California.

OBJECTIVE: To obtain information about health outcomes in neonates in 9 subgroups of the Asian population in the United States. DESIGN: Cross-sectional comparison of outcomes for births to mothers of Cambodian, Chinese, Filipino, Indian, Japanese, Korean, Laotian, Thai, and Vietnamese origin and for births to non-Hispanic white mothers. Regression models were used to compare neonatal mortality across groups before and after controlling for various risk factors. SETTING: All California births between January 1,1991, and December 31, 2001. PARTICIPANTS: More than 2.3 million newborn infants. MAIN EXPOSURE: Racial and ethnic groups. MAIN OUTCOME MEASURE: Neonatal mortality (death within 28 days of birth). RESULTS: The unadjusted mortality rate for births to non-Hispanic white mothers was 2.0 per 1000. The unadjusted mortality rate for births to Chinese and Japanese mothers was significantly lower (Chinese: 1.2 per 1000, P<.001; Japanese: 1.2 per 1000, P=.004), and for births to Korean mothers the rate was significantly higher (2.7 per 1000, P=.003). For infants of Chinese mothers, observed risk factors explain the differences observed in unadjusted data. For infants of Cambodian, Japanese, Korean, and Thai mothers, differences persist or widen after risk factors are considered. After risk adjustment, infants of Cambodian, Japanese, and Korean mothers have significantly lower neonatal mortality rates compared with infants born to non-Hispanic white mothers (adjusted odds ratios, 0.58 for infants of Cambodian mothers, 0.67 for infants of Japanese mothers, and 0.69 for infants of Korean mothers; all P<.05); infants of Thai mothers have higher neonatal mortality rates (adjusted odds ratio, 1.89; P<.05). CONCLUSIONS: There are significant variations in neonatal mortality between subgroups of the Asian American population that are not entirely explained by differences in observable risk factors. Efforts to improve clinical care that treat Asian Americans as a homogeneous group may miss important opportunities for improving infant health in specific subgroups.
