JYNNEOS Vaccination Coverage Among Persons at Risk for Mpox - United States, May 22, 2022-January 31, 2023.

From May 2022 through the end of January 2023, approximately 30,000 cases of monkeypox (mpox) have been reported in the United States and >86,000 cases reported internationally.* JYNNEOS (Modified Vaccinia Ankara vaccine, Bavarian Nordic) is recommended for subcutaneous administration to persons at increased risk for mpox (1,2) and has been demonstrated to provide protection against infection (3-5). To increase the total number of vaccine doses available, the Food and Drug Administration (FDA) issued an Emergency Use Authorization (EUA) on August 9, 2022, recommending administration of the vaccine intradermally (0.1 mL per dose) for persons aged ≥18 years who are recommended to receive it (6); intradermal administration can generate an equivalent immune response to that achieved through subcutaneous injection using approximately one fifth the subcutaneous dose (7). CDC analyzed JYNNEOS vaccine administration data submitted to CDC from jurisdictional immunization information systems (IIS)† to assess the impact of the EUA and to estimate vaccination coverage among the population at risk for mpox. During May 22, 2022-January 31, 2023, a total of 1,189,651 JYNNEOS doses (734,510 first doses and 452,884 second doses)§ were administered. Through the week of August 20, 2022, the predominant route of administration was subcutaneous, after which intradermal administration became predominant, in accordance with FDA guidance. As of January 31, 2023, 1-dose and 2-dose (full vaccination) coverage among persons at risk for mpox is estimated to have reached 36.7% and 22.7%, respectively. Despite a steady decline in mpox cases from a 7-day daily average of more than 400 cases on August 1, 2022, to five cases on January 31, 2023, vaccination for persons at risk for mpox continues to be recommended (1). Targeted outreach and continued access to and availability of mpox vaccines to persons at risk are important to help prevent and minimize the impact of a resurgence of mpox.

Feasibility and acceptability of a toolkit-based process to implement patient-centered, immediate postpartum long-acting reversible contraception services.

BACKGROUND: National guidelines recommend that maternity systems provide patient-centered access to immediate postpartum long-acting reversible contraception (ie, insertion of an intrauterine device or implant during the delivery hospitalization). Hospitals face significant barriers to offering these services, and efforts to improve peripartum contraception care quality have met with mixed success. Implementation toolkits-packages of resources and strategies to facilitate the implementation of new services-are a promising approach for guiding clinical practice change. OBJECTIVE: This study aimed to develop a theory-informed toolkit, evaluate the feasibility of toolkit-based implementation of immediate postpartum long-acting reversible contraception care in a single site, and refine the toolkit and implementation process for future effectiveness testing. STUDY DESIGN: We conducted a single-site feasibility study of the toolkit-based implementation of immediate postpartum contraception services at a large academic medical center in 2017 to 2020. Based on previous qualitative work, we developed a theory-informed implementation toolkit. A stakeholder panel selected toolkit resources to use in a multicomponent implementation intervention at the study site. These resources included tools and strategies designed to optimize implementation conditions (ie, implementation leadership, planning, and evaluation; the financial environment; engagement of key stakeholders; patient needs; compatibility with workflow; and clinician and staff knowledge, skills, and attitudes). The implementation intervention was executed from January 2018 to April 2019. Study outcomes included implementation outcomes (ie, provider perceptions of the implementation process and implementation tools [assessed via online provider survey]) and healthcare quality outcomes (ie, trends in prenatal contraceptive counseling, trends in immediate postpartum long-acting reversible contraceptive utilization [both ascertained by institutional administrative data], and the patient experience of contraceptive care [assessed via serial, cross-sectional, online patient survey items adapted from the National Quality Forum-endorsed, validated Person-Centered Contraceptive Counseling measure]). RESULTS: In the implementation process, among 172 of 401 eligible clinicians (43%) participating in surveys, 70% were "extremely" or "somewhat" satisfied with the implementation process overall. In the prenatal contraceptive counseling, among 4960 individuals undergoing childbirth at the study site in 2019, 1789 (36.1%) had documented prenatal counseling about postpartum contraception. Documented counseling rates increased overall throughout 2019 (Q1, 12.5%; Q4, 51.0%) but varied significantly by clinic site (Q4, range 30%-79%). Immediate postpartum long-acting reversible contraception utilization increased throughout the study period (before implementation, 5.46% of deliveries; during implementation, 8.95%; after implementation, 8.58%). In the patient experience of contraceptive care, patient survey respondents (response rate, 15%-29%) were largely White (344/425 [81%]) and highly educated (309/425 [73%] with at least a 4-year college degree), reflecting the study site population. Scores were poor across settings, with modest improvements in the hospital setting from 2018 to 2020 (prenatal visits, 67%-63%; hospitalization, 45%-58%; outpatient after delivery, 69%-65%). Based on these findings, toolkit refinements included additional resources designed to routinize prenatal contraceptive counseling and support a more patient-centered experience of contraceptive care. CONCLUSION: A toolkit-based process to implement immediate postpartum long-acting reversible contraceptive services at a single academic center was associated with high acceptability but mixed healthcare quality outcomes. Toolkit resources were added to optimize counseling rates and the patient experience of contraceptive care. Future research should formally test the effectiveness of the refined toolkit in a multisite, prospective trial.

Elevating the patient voice in contraceptive care quality improvement: A qualitative study of patient preferences for peripartum contraceptive care.

OBJECTIVE: Patient-centeredness is an important indicator of peripartum contraceptive care quality. Prior work demonstrates how care fragmentation, provider biases, and other factors sometimes undermine the patient-centeredness and quality of this care. To guide the design of future quality improvement interventions, we explored patient preferences for peripartum contraceptive care. STUDY DESIGN: For this qualitative study, we recruited a convenience sample of individuals receiving prenatal care at the study site and participating in an online survey about their experience of peripartum contraceptive care during February-July 2020. We conducted individual, in-depth, semistructured interviews to assess patients' preferences for peripartum contraceptive care. Using inductive and deductive qualitative content analysis, we evaluated interview data for patient preferences for peripartum contraceptive counseling and organized preferences into domains to inform future quality measurement. RESULTS: Interviews (lasting 7-26 min) included 21 postpartum individuals, who were largely White with high levels of formal education. Many participants described suboptimal care experiences characterized by insufficient information, inadequate centering of patient values, and, occasionally, disrespectful care. We identified four key themes describing patients' desire for (1) comprehensive, anticipatory information from one's peripartum provider; (2) counseling and decision-making that (a) prioritize patient preferences and values and (b) avoid pressure; (3) care that respects patient feelings and wishes; and (4) provider responsiveness to individual patient preferences regarding timing and frequency of counseling. CONCLUSIONS: We newly identify four key domains of patient preferences for peripartum contraceptive care. Additional research is needed to understand peripartum contraceptive care preferences among diverse patient populations. Future research should develop validated measures for evaluating the patient experience of peripartum contraceptive care at scale, as part of ongoing efforts to improve the quality and respectfulness of peripartum care. IMPLICATIONS: Patients want peripartum contraceptive care to provide comprehensive, anticipatory information; elicit and respond to their counseling and decision-making preferences; and demonstrate respect for their wishes.

Factors associated with false-positive results from fingerstick OraQuick ADVANCE rapid HIV 1/2 antibody test.

OBJECTIVE: Identify factors associated with false-positive rapid HIV antibody tests. DESIGN: This retrospective cohort study with nested case-controls involved patients tested for HIV by Boston Medical Center (BMC) affiliates. METHODS: Cases had a reactive fingerstick OraQuick ADVANCE rapid HIV 1/2 antibody test and a negative Western blot. Controls had nonreactive rapid tests. We compared the prevalence of HIV risk factors between cases and the total nonreactive population and the prevalence of other clinical factors between cases and controls. RESULTS: Of the 15 094 tests, 14 937 (98.9%) were negative and 11 (0.07%) were false positives (specificity of 99.9%). Cases were more likely to have had an HIV-infected sex partner and to be tested at certain sites compared to true negatives. More cases than controls had O-negative blood type. CONCLUSION: O-negative blood type and sex with an HIV-infected person may increase false-positive HIV fingerstick results. More targeted studies should examine these risk factors.

Socioecological and message framing factors influencing maternal influenza immunization among minority women.

OBJECTIVE: A suboptimal level of seasonal influenza vaccination among pregnant minority women is an intractable public health problem, requiring effective message resonance with this population. We evaluated the effects of randomized exposure to messages which emphasize positive outcomes of vaccination ("gain-frame"), or messages which emphasize negative outcomes of forgoing vaccination ("loss-frame"). We also assessed multilevel social and community factors that influence maternal immunization among racially and ethnically diverse populations. STUDY DESIGN: Minority pregnant women in metropolitan Atlanta were enrolled in the longitudinal study and randomized to receive intervention or control messages. A postpartum questionnaire administered 30 days postpartum evaluated immunization outcomes following baseline message exposure among the study population. We evaluated key outcomes using bivariate and multivariate analyses. RESULTS: Neither gain- [OR=0.5176, (95% CI: 0.203,1.322)] nor loss-framed [OR=0.5000, 95% CI: (0.192,1.304)] messages were significantly associated with increased likelihood of immunization during pregnancy. Significant correlates of seasonal influenza immunization during pregnancy included healthcare provider recommendation [OR=3.934, 95% CI: (1.331,11.627)], use of hospital-based practices as primary source of prenatal care [OR=2.584, 95% CI: (1.091,6.122)], and perceived interpersonal support for influenza immunization [OR=3.405, 95% CI: (1.412,8.212)]. CONCLUSION: Dissemination of vaccine education messages via healthcare providers, and cultivating support from social networks, will improve seasonal influenza immunization among pregnant minority women.

Factors associated with maternal influenza immunization decision-making. Evidence of immunization history and message framing effects.

OBJECTIVE: We examined pregnant women's intention to obtain the seasonal influenza vaccine via a randomized controlled study examining the effects of immunization history, message exposure, and sociodemographic correlates. METHODS: Pregnant women ages 18-50 participated in a randomized message framing study from September 2011 through May 2012. Venue-based sampling was used to recruit racial and ethnic minority women throughout Atlanta, Georgia. Key outcomes were evaluated using bivariate and multivariate analyses. RESULTS: History of influenza immunization was positively associated with intent to immunize during pregnancy [OR=2.31, 90%CI: (1.06, 5.00)]. Significant correlates of intention to immunize included perceived susceptibility to influenza during pregnancy [OR=3.8, 90% CI: (1.75, 8.36)] and vaccine efficacy [OR=10.53, 90% CI: (4.34, 25.50)]. Single message exposure did not influence a woman's intent to vaccinate. CONCLUSIONS: Prior immunization, perceived flu susceptibility and perceived vaccine effectiveness promoted immunization intent among this population of pregnant minority women. Vaccine efficacy and disease susceptibility are critical to promoting immunization among women with no history of seasonal influenza immunization, while those who received the vaccine are likely to do so again. These findings provide evidence for the promotion of repeated exposure to vaccine messages emphasizing vaccine efficacy, normative support, and susceptibility to influenza.
