In March-April, 2020, we communicated with a cohort of criminal justice-involved (CJI) women to see how they were navigating COVID-19, chronic illness, homelessness, and shelter-in-place orders in Oakland, Birmingham, and Kansas City. We report on conversations with N = 35 women (out of the cohort of 474 women) and our own observations from ongoing criminal justice involvement studies. Women reported barriers to protecting themselves given widespread unstable housing and complex health needs, though many tried to follow COVID-19 prevention recommendations. Women expressed dissatisfaction with the suspension of research activities, as the pandemic contributed to a heightened need for study incentives, such as cash, emotional support, and other resources. COVID-19 is illuminating disparities between those who can follow recommended actions to prevent infection and those who lack resources to do so. Concerted efforts are required to reduce inequities that put the 1.3 million U.S. women under criminal justice supervision at risk for infection and mortality.

Few existing studies have examined health and oral health needs and treatment-seeking behavior among the homeless and injection drug users (IDUs). This paper describes the prevalence and correlates of health and oral health care needs and treatment-seeking behaviors in homeless IDUs recruited in San Francisco, California, from 2003 to 2005 (N = 340). We examined sociodemographic characteristics, drug use patterns, HIV status via oral fluid testing, physical health using the Short Form 12 Physical Component Score, self-reported needs for physical and oral health care, and the self-reported frequency of seeking medical and oral health care. The sample had a lower health status as compared to the general population and reported a frequent need for physical and oral health care. In bivariate analysis, being in methadone treatment was associated with care-seeking behavior. In addition, being enrolled in Medi-Cal, California's state Medicaid program, was associated with greater odds of seeking physical and oral health care. Methamphetamine use was not associated with higher odds of needing oral health care as compared to people who reported using other illicit drugs. Homeless IDUs in San Francisco have a large burden of unmet health and oral health needs. Recent cuts in Medi-Cal's adult dental coverage may result in a greater burden of oral health care which will need to be provided by emergency departments and neighborhood dental clinics.

The objective of this article is to compare demographic characteristics, risk behaviors, and service utilization among injection drug users (IDUs) recruited from two separate studies in San Francisco in 2005, one which used targeted sampling (TS) and the other which used respondent-driven sampling (RDS). IDUs were recruited using TS (n = 651) and RDS (n = 534) and participated in quantitative interviews that included demographic characteristics, risk behaviors, and service utilization. Prevalence estimates and 95% confidence intervals (CIs) were calculated to assess whether there were differences in these variables by sampling method. There was overlap in 95% CIs for all demographic variables except African American race (TS: 45%, 53%; RDS: 29%, 44%). Maps showed that the proportion of IDUs distributed across zip codes were similar for the TS and RDS sample, with the exception of a single zip code that was more represented in the TS sample. This zip code includes an isolated, predominantly African American neighborhood where only the TS study had a field site. Risk behavior estimates were similar for both TS and RDS samples, although self-reported hepatitis C infection was lower in the RDS sample. In terms of service utilization, more IDUs in the RDS sample reported no recent use of drug treatment and syringe exchange program services. Our study suggests that perhaps a hybrid sampling plan is best suited for recruiting IDUs in San Francisco, whereby the more intensive ethnographic and secondary analysis components of TS would aid in the planning of seed placement and field locations for RDS.

The rise in drug overdoses and harms associated with the use of more than one substance has led to increased use of the term "polysubstance use" among researchers, clinicians, and public health officials. However, the term retains no consistent definition across contexts. The current authors convened from disciplines including sociology, epidemiology, neuroscience, and addiction psychiatry to propose a recommended definition of polysubstance use. An iterative process considered authors' formal and informal conversations, insights from relevant symposia, talks, and conferences, as well as their own research and clinical experiences to propose the current definition. Three key concepts were identified as necessary to define polysubstance use: (1) substances involved, (2) timing, and (3) intent. Substances involved include clarifying either (1) the number and type of substances used, (2) presence of more than one substance use disorder, or (3) primary and secondary substance use. The concept of timing is recommended to use clear terms such as simultaneous, sequential, and same-day polysubstance use to describe short-term behaviors (e.g., 30-day windows). Finally, the concept of intent refers to clarifying unintentional use or exposure when possible, and greater attention to motivations of polysubstance use. These three components should be clearly defined in research on polysubstance use to improve consistency across disciplines. Consistent definitions of polysubstance use can aid in the synthesis of evidence to better address an overdose crisis that increasingly involves multiple substances. [ABSTRACT FROM AUTHOR]

The COVID-19 outbreak fueled unprecedented public health efforts to mitigate the spread of infection, including rapid provision of non-congregate housing to people experiencing homelessness. People on community supervision (criminal probation or parole) have high levels of homelessness due to housing discrimination, poverty and racism, and are among the groups most vulnerable to COVID-19. We examined housing status in a cohort of women with probation histories in Alameda County, CA before and after the COVID-19 outbreak (N = 204). Before March 2020, 38% of women in the cohort reporting being homeless (95% CI: 34–43%), a level that was consistent over 12 months. As of August 2020, 15% of the cohort was homeless (95% CI: 10–20%; relative risk [RR] 0.40, 95% CI: 0.28, 0.55; p < 0.001). During a period of assertive public health efforts to reduce COVID-19 risk through provision of housing, we found meaningful reductions in homelessness in this sample of vulnerable women.
