Successful Distribution of Tecovirimat During the Peak of the Mpox Outbreak - Los Angeles County, June 2022-January 2023.

Tecovirimat is the first-line antiviral treatment recommended for severe mpox or for persons with mpox who are at risk for severe disease; tecovirimat is available in the United States under an expanded access investigational new drug (IND) protocol. During the 2022-2023 mpox outbreak, local U.S. health jurisdictions facilitated access to tecovirimat. In June 2022, Los Angeles County (LAC) rapidly developed strategies for tecovirimat distribution using existing medical countermeasure distribution networks established by the Public Health Emergency Preparedness Program and the Hospital Preparedness Program, creating a hub and spoke distribution network consisting of 44 hub facilities serving 456 satellite sites across LAC. IND patient intake forms were analyzed to describe mpox patients treated with tecovirimat. Tecovirimat treatment data were matched with case surveillance data to calculate time from specimen collection to patients receiving tecovirimat. Among 2,281 patients with mpox in LAC, 735 (32%) received tecovirimat during June 2022-January 2023. Among treated patients, approximately two thirds (508; 69%) received treatment through community clinics and pharmacies. The median interval from specimen collection to treatment was 2 days (IQR = 0-5 days). Local data collection and analysis helped to minimize gaps in treatment access and facilitated network performance monitoring. During public health emergencies, medical countermeasures can be rapidly deployed across a large jurisdiction using existing distribution networks, including clinics and pharmacies.

Effectiveness of JYNNEOS vaccine against symptomatic mpox disease in adult men in Los Angeles County, August 29, 2022 to January 1, 2023.

We describe real-world estimates of JYNNEOS vaccine effectiveness (VE) against symptomatic mpox in Los Angeles County (LAC). We conducted a retrospective cohort study of men aged ≥18 years residing in LAC who were at risk for mpox and eligible for the JYNNEOS vaccine from 5/19/2022 to 1/1/2023. Case demographics and route of JYNNEOS administration were obtained through vaccine administration data systems. HIV and sexually transmitted infection (STI) status was obtained through disease reporting systems for HIV and STI diagnoses in LAC. To estimate VE, we calculated weekly incidence of confirmed mpox for unvaccinated, partially vaccinated (episode date ≥14 days after first dose), and fully vaccinated (episode date ≥14 days after second dose) cohorts starting on 8/29/2022, when fully vaccinated coverage exceeded 3 %, and ending on 1/1/2023. Overall, 2,171 men had confirmed mpox, and 1,002 (46 %) of those were persons living with diagnosed HIV (PLWDH). 2,019 (93 %) mpox cases were unvaccinated, 114 (5 %) were partially vaccinated and 38 (2 %) were fully vaccinated. VE was 69 % (95 % CI 59-77) for partially vaccinated and 84 % (95 % CI 80-87) for fully vaccinated individuals. Among PLWDH, VE was 72 % (95 % CI 57-82) for fully vaccinated and 28 % (95 % CI -96 to 73) VE for partially vaccinated individuals. Among persons not living with diagnosed HIV, VE was 88 % (95 % CI 86-90) for fully vaccinated and 80 % (95 % CI 76-83) for partially vaccinated individuals. Of 111 individuals hospitalized with mpox, one was partially vaccinated, and the remaining were unvaccinated. Our results align with other published studies that reported that two doses of the JYNNEOS vaccine provided significant protection against symptomatic mpox.

Will prior health insurance authorization for medications continue to hinder hepatitis C treatment delivery in the United States? Perspectives from hepatitis C treatment providers in a large urban healthcare system.

BACKGROUND: The recent introduction of direct acting antivirals for the treatment of hepatitis C virus (HCV) has dramatically improved treatment options for HCV infected patients. However, in the United States (US) treatment uptake has been low and time to initiation of therapy has been long. We sought to examine provider perspectives of facilitators and barriers to HCV treatment delivery. METHODS: From June to August 2019, we conducted in-depth, semi-structured interviews with medical staff providing HCV care as part of a university medical center in Los Angeles, CA. In order to understand the HCV treatment process, we interviewed key staff members providing care to the majority of HCV patients seeking care at the university medical center, including hepatologists and infectious disease specialists as well as key nursing and pharmacy staff. The interviews focused on workload and activities required for HCV treatment initiation for non-cirrhotic, treatment naïve patients. RESULTS: Providers noted that successful HCV treatment delivery was reliant on a care model involving close collaboration between a team of providers, in particular requiring a highly coordinated effort between dedicated nursing and pharmacy staff. The HCV care team overwhelmingly reported that the process of insurance authorization was the greatest obstacle delaying treatment initiation and noted that very few patient level factors served as a barrier to treatment uptake. CONCLUSIONS: In the US, prior authorization for HCV treatment is a requirement for most public and private insurance plans. In an era with access to therapies that allow for a cure-and until revocation of prior authorization for HCV treatment is a reality-implementing strategies that can expedite authorization to accelerate treatment access are critical. Not only will this benefit patients, but it has the potential to help expand treatment to settings that are otherwise too resource strained to successfully deliver HCV care.
