Overdose from Unintentional Fentanyl Use when Intending to Use a Non-opioid Substance: An Analysis of Medically Attended Opioid Overdose Events.

Fentanyl-mixed and substituted heroin is well-documented, but less is known about unintentional fentanyl use among people using stimulants. To determine the prevalence of and racial and ethnic disparities in unintentional fentanyl use among people experiencing a medically attended opioid overdose, we reviewed 448 suspected non-fatal overdose cases attended by a community paramedic overdose response team in San Francisco from June to September 2022. We applied a case definition for opioid overdose to paramedic records and abstracted data on intended substance use prior to overdose. Among events meeting case criteria with data on intended substance use, intentional opioid use was reported by 57.3%, 98.0% of whom intended to use fentanyl. No intentional opioid use was reported by 42.7%, with most intending to use stimulants (72.6%), including methamphetamine and cocaine. No intentional opioid use was reported by 58.5% of Black, 52.4% of Latinx, and 28.8% of White individuals (p = 0.021), and by 57.6% of women and 39.5% of men (p = 0.061). These findings suggest that unintentional fentanyl use among people without opioid tolerance may cause a significant proportion of opioid overdoses in San Francisco. While intentional fentanyl use might be underreported, the magnitude of self-reported unintentional use merits further investigation to confirm this phenomenon, explore mechanisms of use and disparities by race and ethnicity, and deploy targeted overdose prevention interventions.

"You can't go wrong being safe": Motivations, patterns, and context surrounding use of fentanyl test strips for heroin and other drugs.

BACKGROUND: Unintentional drug overdose fatalities due to fentanyl contamination continue to increase. Fentanyl test strip (FTS) use has emerged as a valuable harm reduction strategy to detect the presence of fentanyl in drugs. However, motivation for FTS uptake and context surrounding use have not been well characterized in the literature. This study aimed to capture people who use drugs' (PWUD) lived experiences to understand motivations underlying FTS uptake, ongoing use, and actions after testing. METHODS: We conducted qualitative interviews with PWUD at a harm reduction organization in Philadelphia, PA. Interviews asked about experiences with using FTS. Interviews were audio-recorded, professionally transcribed, and reviewed. Data were analyzed through a conventional content analysis approach and organized into broader categories via team consensus. RESULTS: Twenty-nine PWUD with experience using FTS were interviewed between January and May 2021. Interviews were organized into three thematic categories: first time use of FTS, patterns of FTS use, and contextual factors of FTS use. Motivations to use FTS among PWUD varied, but were largely driven by factors related to knowledge, access, neighborhood, and drug market trends. Frequency of use was characterized by number of FTS, ongoing FTS access, and drug purchasing location and amount. Participants reported few logistical barriers to testing. CONCLUSION: This research supports the current literature that states FTS are an accepted and effective harm reduction strategy for the PWUD community. To support increased use of FTS, distribution campaigns should be widespread geographically and provide enough strips to ensure availability for PWUD to test more frequently.

Hospitalist perspectives on buprenorphine treatment for inpatients with opioid use disorder.

Background: Patients with opioid use disorder (OUD) have high hospital admission rates. Hospitalists, clinicians that work in inpatient medical settings, may have a unique opportunity to intervene on behalf of these patients, yet their experience with and attitudes towards treating patients with OUD need further exploration. Methods: We conducted qualitative analysis of 22 semi-structured interviews with hospitalists between January and April 2021 in Philadelphia, PA. Participants were hospitalists in one major metropolitan university hospital and one urban community hospital in a city with a high prevalence of OUD and overdose deaths. Participants were asked about their experiences, successes, and difficulties in treating hospitalized patients with OUD. Results: Twenty-two hospitalists were interviewed. Participants were majority female (14, 64%) and White (16, 73%). We identified the following common themes: lack of training/experience with OUD, a lack of community OUD treatment infrastructure, a lack of inpatient OUD/withdrawal treatment resources, the "X-waiver" as a barrier to prescribing buprenorphine, the "ideal" patient to start on buprenorphine, and the hospital as an ideal intervention setting. Conclusions: Hospitalization due to acute illness or complication of drug use represents a potential intervention point to initiate treatment for patients with OUD. While hospitalists exhibit willingness to prescribe medications, provide harm reduction education, and link patients to outpatient addiction treatment, they identify training and infrastructure barriers that must first be addressed.

Maintaining Safety Standards While Building an Urban Alternate Care Facility in a Global Pandemic.

The Philadelphia region responded to the shortage of health care resources imposed by the 2020 COVID-19 pandemic through the creation of the COVID-19 Surge Facility at Temple University's basketball arena. The facility was designed as an acute care medical unit capable of supporting COVID-19 patients who were stable enough to be released from the intensive care unit but not ready for discharge home. Safety was optimized through the application of recommendations from the Joint Commission and Centers for Disease Control and Prevention (CDC). The safety goals include those established by the Joint Commission with regard to patient identification, security, identification of patient safety threats, communication, fire safety, laboratory services, and pharmacologic services. COVID-19-specific goals outlined by the CDC also are addressed and include recommendations for facility layout, managing staff respite and personal protective equipment, patient care areas, supply storage, airflow, and patient hygiene. Although the goal was to meet all of these recommendations, some were not possible due to the austere environment of the arena. However, these shortcomings were met with innovative solutions that provided the next best options. By sharing these experiences, the authors hope to guide future alternate care facilities in their efforts to optimize safety.

Adherence to buprenorphine: An analysis of prescription drug monitoring program data.

BACKGROUND: Although buprenorphine is an evidence-based treatment for opioid use disorder (OUD), many individuals discontinue treatment soon after starting. This study assesses predictors of buprenorphine adherence using Prescription Drug Monitoring Program (PDMP) data. METHODS: PDMP data for Philadelphia, Pennsylvania were used to measure 180-day adherence to buprenorphine among new initiates. Adherence was classified using percent days covered (PDC), and new initiates with PDC ≥ 0.80 were classified as adherent. Multivariable logistic regression was conducted to determine factors associated with buprenorphine adherence. RESULTS: Between January 2017 and December 2018, 10,669 Philadelphia residents initiated buprenorphine and 26.6 % remained adherent after 180 days. Demographic factors associated with greater odds of adherence included age category and female sex (aOR: 1.37; 95 % CI: 1.25-1.50). Those filling an opioid prescription, other than buprenorphine, during the follow-up period had lower odds of adherence than those who did not fill an opioid prescription (aOR: 0.62; 95 % CI: 0.50-0.77). Odds of adherence was greater for those on the film formulation (aOR: 1.37; 95 % CI: 1.25-1.50) than the tablet formulation. Those filling medium (aOR: 1.76; 95 % CI: 1.55-2.00) and high dose (aOR: 5.11; 95 % CI: 4.30-6.17) buprenorphine prescriptions had higher odds of adherence than those filling low dose prescriptions. CONCLUSIONS: Individual demographics, receipt of an opioid prescription, buprenorphine formulation, and buprenorphine dose were all associated with adherence to buprenorphine. Ongoing strategies to address OUD need to prioritize increasing retention in long-term evidence-based buprenorphine treatment while also encouraging providers to regularly consult the PDMP to ensure patient compliance.

Access to primary and dental care among adults newly enrolled in Medicaid.

OBJECTIVES: Adequate access to primary and dental care is essential for population health, and some state Medicaid programs have expanded insurance coverage for both. However, there are few data on new Medicaid enrollees' ability to access services. We examined the relationship between provider supply and enrollees' identification of usual sources of care. STUDY DESIGN: Between November 2015 and February 2016, we surveyed low-income adults newly insured through Medicaid in Philadelphia, Pennsylvania, to determine if they had a usual source of care. Additionally, we used geospatial methods to calculate adult population per provider ratios by Census tract for primary and dental care providers who accepted Medicaid patients, then identified low-supply clusters. METHODS: We used multivariable logistic regression models to describe the odds of identifying usual sources of care based on being in low- or high-supply clusters, adjusting for patient demographics. RESULTS: Of 1000 contacted individuals, 312 completed the survey. Among respondents, 168 were previously uninsured and newly enrolled in Medicaid; 66.7% of this group identified a usual primary care provider and 42.3% identified a usual dental care provider. In adjusted analyses, individuals living in low- and high-supply areas had similar likelihoods of identifying a usual source of primary or dental care. CONCLUSIONS: Many new Medicaid enrollees did not have usual sources of primary or dental care, regardless of nearby provider supply. Efforts to understand what improves access or engagement in healthcare among Medicaid enrollees are critical after low-income adults gain insurance.

Increased Health and Social Vulnerability Among Hepatitis C Infected Individuals Co-infected with Hepatitis B.

Hepatitis B (HBV) and hepatitis C (HCV) infections contribute significant morbidity in the United States, particularly among those with a history of incarceration, homeless-ness, and/or co-morbid mental illness. Data from the Philadelphia Department of Public Health's viral hepatitis registry were matched at the person-level to the city's shelter, jail, and mental health system datasets (vulnerability datasets), and descriptive statistics were calculated. Between January 2010 and December 2014, 29,807 cases of HCV and 133 cases of HBV/HCV were reported. Fifty-eight percent of HCV cases and 70% of HBV/HCV cases were found in at least one vulnerability dataset. Compared with HCV cases, HBV/HCV cases were more likely to have a mental health diagnosis and history of incarceration, and to have spent more days in jail, and were less likely to be receiving treatment for HCV. Data are needed to describe more adequately the trajectory of HBV/HCV co-infected individuals to improve health service planning and policy.

Evaluating the association between the built environment and primary care access for new Medicaid enrollees in an urban environment using Walk and Transit Scores.

Worse health outcomes among those living in poverty are due in part to lower rates of health insurance and barriers to care. As the Affordable Care Act reduced financial barriers, identifying persistent barriers to accessible health care continues to be important. We examined whether the built environment as reflected by Walk Score™ (a measure of walkability to neighborhood resources) and Transit Score™ (a measure of transit access) is associated with having a usual source of care among low-income adults, newly enrolled in Medicaid. We received responses from 312 out of 1000 new Medicaid enrollees in Philadelphia, a large, densely populated urban area, who were surveyed between 2015 and 2016 to determine if they had identified a usual source of outpatient primary care. Respondents living at an address with a low Walk Scores (< 70) had 84% lower odds of having a usual source of care (OR 0.16, 95% CI 0.04-0.61). Transit scores were not associated with having a usual source of care. Walk Score may be a tool for policy makers and providers of care to identify populations at risk for worse primary care access.

Effect of Outreach Messages on Medicaid Enrollment.

OBJECTIVES: To measure the impact of different outreach messages on health insurance enrollment among Medicaid-eligible adults. METHODS: Between March 2015 and April 2016, we conducted a series of experiments using mail-based outreach that encouraged individuals to enroll in Pennsylvania's expanded Medicaid program. Recipients were randomized to receive 1 of 4 different messages describing the benefits of health insurance. The primary outcome was the response rate to each letter. RESULTS: We mailed outreach letters to 32 993 adults in Philadelphia. Messages that emphasized the dental benefits of insurance were significantly more likely to result in a response than messages emphasizing the health benefits (odds ratio = 1.33; 95% confidence interval = 1.10, 1.61). CONCLUSIONS: Medicaid enrollment outreach messages that emphasized the dental benefits of insurance were more effective than those that emphasized the health-related benefits. Public Health Implications. Although the structure and eligibility of the Medicaid program are likely to change, testing and identifying successful outreach and enrollment strategies remains important. Outreach messages that emphasize dental benefits may be more effective at motivating enrollment among individuals of low socioeconomic status.

Variation in the Viral Hepatitis and HIV Policies and Practices of Methadone Maintenance Programs.

OBJECTIVE: Patients prescribed methadone maintenance treatment (MMT) demonstrate elevated prevalence of hepatitis B virus (HBV), hepatitis C virus, and HIV. Government agencies recommend testing for these infections in MMT programs, but uptake is limited. METHODS: We audited infection-related policies and practices of all 14 MMT programs in Philadelphia, Pennsylvania, in 2015. Results were tabulated and compared with the results from a 2010 audit of 10 of 12 MMT programs. The audit focused on which patients are tested, timing and frequency, specific tests ordered, vaccination, and communication of test results. RESULTS: Written policies were nonspecific, offering little guidance on appropriate testing. The principal change in policy between 2010 and 2015 involved adding clearer guidance for communication of results to patients. In 2010 and 2015, all MMT programs tested new patients for hepatitis C virus antibodies, although retesting of existing patients varied. HBV testing increased from 2010 to 2015, though it was not uniform, with 5 programs testing for HBV surface antibodies and 10 programs testing for HBV surface antigens. Six programs assessed hepatitis vaccination status, but only 1 administered vaccines. In 2010, city-sponsored HIV antibody testing was available at all MMT programs. Without this program in 2015, few MMT programs conducted HIV testing. CONCLUSIONS: Despite limited hepatitis and HIV screening in MMT programs nationally, this study shows that testing can be incorporated into routine procedures. MMT programs are positioned to play an integral role in the identification of patients with chronic infections, but additional guidance and resources are required to maximize their impact.

New Medicaid Enrollees See Health and Social Benefits in Pennsylvania's Expansion.

Understanding how new Medicaid enrollees are approaching their own health and health care in the shifting health care landscape of the Affordable Care Act has implications for future outreach and enrollment efforts, as well as service planning for this population. The objective of this study was to explore the health care experiences and expectations of new Medicaid expansion beneficiaries in the immediate post-enrollment period. We conducted semistructured, qualitative interviews with a random sample of 40 adults in Philadelphia who had completed an application for Medicaid through a comprehensive benefits organization after January 1, 2015, when the Medicaid expansion in Pennsylvania took effect. We conducted an inductive, applied thematic analysis of interview transcripts. The new Medicaid beneficiaries described especially high levels of pent-up demand for care. Dental care was a far more pressing and motivating concern than medical care. Preventive services were also frequently mentioned. Participants anticipated that insurance would reduce both stress and financial strain and improve their experience in the health care system by raising their social standing. Participants highly valued the support of telephone application counselors in the Medicaid enrollment process to overcome bureaucratic obstacles they had encountered in the past. Dental care and preventive services appear to be high priorities for new Medicaid enrollees. Telephone outreach and enrollment support services can be an effective way to overcome past experiences with administrative barriers.

Drug-resistant tuberculosis among HIV-infected patients starting antiretroviral therapy in Durban, South Africa.

OBJECTIVE: To estimate the prevalence of drug-resistant tuberculosis (TB) and describe the resistance patterns in patients commencing antiretroviral therapy (ART) in an HIV clinic in Durban, South Africa. DESIGN: Cross-sectional cohort study. METHODS: Consecutive HIV-infected adults (≥ 18y/o) initiating HIV care were enrolled from May 2007-May 2008, regardless of signs or symptoms of active TB. Prior TB history and current TB treatment status were self-reported. Subjects expectorated sputum for culture (MGIT liquid and 7H11 solid medium). Positive cultures were tested for susceptibility to first- and second-line anti-tuberculous drugs. The prevalence of drug-resistant TB, stratified by prior TB history and current TB treatment status, was assessed. RESULTS: 1,035 subjects had complete culture results. Median CD4 count was 92/µl (IQR 42-150/µl). 267 subjects (26%) reported a prior history of TB and 210 (20%) were receiving TB treatment at enrollment; 191 (18%) subjects had positive sputum cultures, among whom the estimated prevalence of resistance to any antituberculous drug was 7.4% (95% CI 4.0-12.4). Among those with prior TB, the prevalence of resistance was 15.4% (95% CI 5.9-30.5) compared to 5.2% (95% CI 2.1-8.9) among those with no prior TB. 5.1% (95% CI 2.4-9.5) had rifampin or rifampin plus INH resistance. CONCLUSIONS: The prevalence of TB resistance to at least one drug was 7.4% among adults with positive TB cultures initiating ART in Durban, South Africa, with 5.1% having rifampin or rifampin plus INH resistance. Improved tools for diagnosing TB and drug resistance are urgently needed in areas of high HIV/TB prevalence.
