The Tenacious Treponema: A Retrospective Examination of Syphilis Treatment Disparities in Washington, DC.

BACKGROUND: Since 2000, there have been rising rates of syphilis infections nationally with higher incidence among minorities and persons living with human immunodeficiency virus (HIV) (PLWH). The purpose of this study was to determine syphilis treatment adequacy and factors associated with treatment delay. METHODS: This was a retrospective academic-public health collaboration with the District of Columbia Department of Public Health reviewing surveillance data of all primary, secondary, and early latent syphilis cases diagnosed between January 1, 2015, and December 31, 2019. Data were analyzed using multivariable logistic regression to identify factors associated with delayed treatment >14 days from diagnosis. RESULTS: Among 1852 individuals diagnosed with early syphilis, 93% (1730/1852) were male; 48% (893/1852) were coinfected with HIV; 43% (n = 796/1852) were African American/Black, 27% (n = 492/1852) were White, and race/ethnicity was unknown for 17% (n = 318/1852) of cases. Among 679 PLWH for whom viral load (VL) was known, 41% (278/679) had a VL < 20 copies/mL, and 18% (123/679) had VL >10,000 copies/mL. Treatment adequacy overall was 96.5%. Median time to syphilis treatment was 6 days (interquartile range = 4-7). Factors associated with delay of treatment included refused/unknown race (adjusted odds ratio [aOR], 1.95; 95% confidence interval [CI], 1.00-3.79), and HIV VL > 10,000 copies/mL (aOR, 1.97; 95% CI, 1.08-3.58). CONCLUSIONS: The factors we identified associated with delayed treatment may reflect systemic factors contributing to the increased rates of infection among key populations. This highlights the importance of targeted public health efforts with the goal of reducing transmission of both HIV and syphilis.

Implementation of an Educational Intervention to Improve HIV Pre-Exposure Prophylaxis Services for Women in an Urban Sexual Health Clinic.

To test the hypothesis that implementation of a multicomponent, educational HIV pre-exposure prophylaxis (PrEP) intervention to promote universal PrEP services for cisgender women (subsequently "women") in sexual and reproductive health centers would improve the proportion of women screened, offered, and prescribed PrEP, we implemented a multicomponent, educational intervention in a Washington D.C. Department of Health-sponsored sexual health clinic. The clinic serves a patient population with high-potential exposure to HIV. The intervention included clinic-wide PrEP trainings, an electronic health record prompt for PrEP counseling by providers, and educational videos in the waiting room. We collected preimplementation data from March 22, 2018 to July 4, 2018, including 331 clinical encounters for 329 women. Between July 5, 2018 and July 1, 2019, there were 1733 clinical encounters for 1720 HIV-negative women. We used mixed methods to systematically assess intervention implementation using the Reach Effectiveness Adoption Implementation Maintenance framework. Additionally, we assessed the interventions' acceptability and feasibility among providers through semistructured interviews. The proportion of women screened by providers for PrEP (5.6% preimplementation to a mean of 89.2% of women during the implementation period, p < 0.01), offered (6.2 to 69.8%, p < 0.01), and prescribed PrEP (2.6 to 8.1%, p < 0.01) by providers increased significantly in the implementation period. Providers and clinic staff found the intervention both highly feasible and acceptable and demonstrated increased knowledge of PrEP and HIV prevention associated with the clinic-wide trainings. Our results demonstrate the effectiveness of a low-cost educational intervention to increase provision of integrated PrEP services in an urban sexual health clinic serving women with high-potential exposure to HIV.

Pressure Injuries: Prevention, Evaluation, and Management.

Pressure injuries are localized damage to skin or soft tissue. They commonly occur over bony prominences and often present as an intact or open wound. Pressure injuries are common and costly, and they significantly impact patient quality of life. Comprehensive skin assessments are crucial for evaluating pressure injuries. Staging of pressure injuries should follow the updated staging system of the National Pressure Injury Advisory Panel. Risk assessments allow for appropriate prevention and care planning, and physicians should use a structured, repeatable approach. Prevention of pressure injuries focuses on assessing and optimizing nutritional status, repositioning the patient, and providing appropriate support surfaces. Treatment involves pressure off-loading, nutritional optimization, appropriate bandage selection, and wound site management. Pressure injuries and surrounding areas should be cleaned, with additional debridement of devitalized tissue and biofilm if necessary. All injuries should be monitored for local infection, biofilms, and osteomyelitis. Appropriate wound dressings should be selected based on injury stage and the quality and volume of exudate.

Intention to Initiate HIV Pre-exposure Prophylaxis Among Cisgender Women in a High HIV Prevalence U.S. City.

OBJECTIVE: Our objective was to identify the individual, interpersonal, community, health-system, and structural factors that influence HIV pre-exposure prophylaxis (PrEP) initiation among cisgender women seeking sexual and reproductive health care in a high HIV prevalence community to inform future clinic-based PrEP interventions. METHODS: We collected anonymous, tablet-based questionnaires from a convenience sample of cisgender women in family planning and sexual health clinics in the District of Columbia. The survey used the lens of the socio-ecological model to measure individual, interpersonal, community, institutional, and structural factors surrounding intention to initiate PrEP. The survey queried demographics, behavioral exposure to HIV, perceived risk of HIV acquisition, a priori awareness of PrEP, intention to initiate PrEP, and factors influencing intention to initiate PrEP. RESULTS: A total of 1437 cisgender women completed the survey. By socio-ecological level, intention to initiate PrEP was associated with positive attitudes toward PrEP (odds ratio [OR], 1.56; 95% confidence interval [CI], 1.13-2.15) and higher self-efficacy (OR, 1.32; 95% CI, 1.02-1.72) on the individual level, perceived future utilization of PrEP among peers and low fear of shame/stigma (OR, 1.65; 95% CI, 1.33-2.04) on the community level, and having discussed PrEP with a provider (OR. 2.39; 95% CI, 1.20-4.75) on the institutional level. CONCLUSION: Our findings highlight the importance of multilevel, clinic-based interventions for cisgender women, which promote sex-positive and preventive PrEP messaging, peer navigation to destigmatize PrEP, and education and support for women's health medical providers in the provision of PrEP services for cisgender women.

Approach to Elevated Liver Enzymes.

Abnormal liver tests are one of the most common challenges in the primary care setting. Primary care practitioners order these tests for numerous reasons, including investigating abdominal signs and symptoms or suspected alcohol-use disorder, or to determine medication adverse effects. Evaluation should be guided by both the clinical presentation and the pattern of injury. In this article, we will focus on the epidemiology, pathophysiology, clinical presentation, diagnostic work-up, and management of elevated liver enzymes, with an emphasis on the most common causes of abnormal liver testing.

Lessons learned from U.S. rapid antiretroviral therapy initiation programs.

BACKGROUND: Rapid antiretroviral therapy initiation (R-ART) for treatment of HIV has been recommended since 2017, however it has not been adopted widely across the US. PURPOSE: The study purpose was to understand facilitators and barriers to R-ART implementation in the U.S. RESEARCH DESIGN: This was a qualitative design involving semi-structured interviews. STUDY SAMPLE: The study sample was comprised of the medical leadership of nine US HIV clinics that were early implementers of R-ART. DATA COLLECTION AND ANALYSIS: In-depth, semi-structured interviews were performed. The Consolidated Framework for Implementation Research (CFIR) was used to guide thematic analysis. RESULTS: We identified three main content areas: strong scientific rationale for R-ART, buy-in from multiple key stakeholders, and the condensed timeline of R-ART. The CFIR construct of Evidence Strength and Quality was cited as an important factor in R-ART implementation. Buy-in from key stakeholders and immediate access to medications ensured the success of R-ART implementation. Patient acceptance of the condensed timeline for ART initiation was facilitated when presented in a patient-centered manner, including empathetic communication and addressing other patient needs concurrently. The condensed timeline of R-ART presented logistical challenges and opportunities for the development of intense patient-provider relationships. CONCLUSIONS: Results from the analysis showed that R-ART implementation should address the following: 1) logistical planning to implement HIV treatment with a condensed timeline 2) patients' mixed reactions to a new HIV diagnosis and 3) the high cost of HIV medications.

Migraine care practices in primary care: results from a national US survey.

BACKGROUND: Primary care clinicians play a critical role in diagnosis and treatment of migraine, yet barriers exist. This national survey assessed barriers to diagnosis and treatment of migraine, preferred approaches to receiving migraine education, and familiarity with recent therapeutic innovations. METHODS: The survey was created by the American Academy of Family Physicians (AAFP) and Eli Lilly and Company and distributed to a national sample through the AAFP National Research Network and affiliated PBRNs from mid-April through the end of May 2021. Initial analyses were descriptive statistics, ANOVAs, and Chi-Square tests. Individual and multivariate models were completed for: adult patients seen in a week; respondent years since residency; and adult patients with migraine seen in a week. RESULTS: Respondents who saw fewer patients were more likely to indicate unclear patient histories were a barrier to diagnosing. Respondents who saw more patients with migraine were more likely to indicate the priority of other comorbidities and insufficient time were barriers to diagnosing. Respondents who had been out of residency longer were more likely to change a treatment plan due to attack impact, quality of life, and medication cost. Respondents who had been out of residency shorter were more likely to prefer to learn from migraine/headache research scientists and use paper headache diaries. CONCLUSIONS: Results demonstrate differences in familiarity with migraine diagnosis and treatment options based on patients seen and years since residency. To maximise appropriate diagnosis within primary care, targeted efforts to increase familiarity and decrease barriers to migraine care should be implemented.

Factors Associated with Intention to Initiate Pre-exposure Prophylaxis in Cisgender Women at High Behavioral Risk for HIV in Washington, D.C.

Pre-exposure prophylaxis (PrEP) for HIV prevention is underutilized by cisgender women at risk for HIV in the USA. Published research on PrEP initiation among cisgender women at risk for HIV focuses on identifying barriers and facilitators associated with intention to initiate, but few apply a behavioral theoretical lens to understand the relative importance of these diverse factors. This study provides a theoretically grounded view of the relative importance of factors associated with intention to initiate PrEP. We conducted an anonymous, cross-sectional survey of 1437 cisgender women seeking care at family planning and sexual health clinics to evaluate hypothesized barriers and facilitators of PrEP initiation. We categorized cisgender women with ≥ 3 behavioral risk-factors as "high-risk" for HIV acquisition; 26.9% (N = 387) met high-risk criterion. Among cisgender women in the high-risk sample, the majority were Black and single. Perceived risk of HIV acquisition was low and 13.7% reported intention to initiate PrEP. Positive attitudes toward PrEP, self-efficacy, perceived support from medical providers and social networks, and prior discussion about PrEP with medical providers were associated with intention to initiate PrEP; stigma was negatively associated. Background characteristics (other than age), risk factors for HIV acquisition, prior awareness of PrEP, and perceived risk of HIV were not associated with uptake intention. These findings support interventions that center on the role of providers in the provision of PrEP and on social networks in destigmatization of PrEP use.

A Pilot of Mail-Out HIV and Sexually Transmitted Infection Testing in Washington, District of Columbia During the COVID-19 Pandemic.

INTRODUCTION: In 2019, the District of Columbia recorded a 20-year low rate in new HIV infections but also had near-record numbers of gonorrhea and chlamydia infections. District of Columbia Department of Health has supported numerous forms of community-based in-person screening but not direct at-home testing. METHODS: In summer 2020, the District of Columbia Department of Health launched GetCheckedDC.org for District of Columbia residents to order home-based oral HIV antibody test and urogenital, pharyngeal, and rectal chlamydia and gonorrhea tests. Initial and follow-up surveys were completed by individuals for both test modalities. RESULTS: A retrospective analysis was conducted for the first 5 months of the program. During that period, 1,089 HIV and 1,262 gonorrhea and chlamydia tests (535 urogenital, 520 pharyngeal, 207 rectal) were ordered by 1,245 District of Columbia residents. The average age was 33.1 (median=31, range=14-78) years; 51.6% of requestors identified as Black; 39.3% identified as men who have sex with men; 16.2% reported no form of insurance; and 8.1% and 10.4% reported never being testing for HIV and sexually transmitted infections, respectively. More than half of people requesting tests reported convenience and COVID-19 as the reasons. In total, 39.5% of sexually transmitted infection tests were returned; 7.22% of people testing for sexually transmitted infections received a positive result, and 10.35% of rectal tests were positive. No individuals reported a positive HIV self-test that was confirmed; 98.5% of respondents said that they would recommend the HIV self-test kit. CONCLUSIONS: Mail-out HIV and sexually transmitted infection testing was readily taken up among high-priority demographics within a diverse, urban, high-morbidity jurisdiction during the COVID-19 pandemic. Extragenital testing for gonorrhea and chlamydia should be included in all at-home screening tests given the high positivity rate.

Harm Reduction: Assessing the Educational Needs of Family Medicine Residents in Care of Persons Who Inject Drugs.

BACKGROUND AND OBJECTIVES: Rates of injection drug use and associated medical complications have increased, yet engagement of persons who inject drugs (PWID) in primary care is limited, with significant barriers to care. Family physicians play an important role in caring for PWID, but residency training is limited. This study aimed to assess role responsibility, self-efficacy, and attitudes of family medicine residents in caring for PWID. METHODS: Using a cross sectional design, family medicine residents in 2018 at three different programs completed Likert and open-ended survey questions assessing role responsibility, self-efficacy, and attitudes in caring for PWID. RESULTS: Fifty-five percent (41/76) of residents completed surveys. Residents consistently agreed it is their responsibility to provide comprehensive care for PWID, while being less confident in key elements of screening, brief intervention, and referral to treatment (SBIRT). The largest gap between responsibility and confidence was in referral to treatment. Resident confidence was lowest for harm reduction strategies: discussing clean needle practices, prescribing naloxone and referral to medication-assisted treatment or needle exchange programs. Less than 60% of residents agreed they are able to work with or understand PWID. CONCLUSIONS: This study identifies gaps between provider responsibility and current graduate medical education training. We identified training that increases screening, harm reduction practices, and referrals to community resources as needs. This baseline assessment of family medicine residents can be used to develop educational interventions to meet regional and national health needs for harm reduction for PWID and workforce development.

Knowledge, Attitudes, and Behaviors Related to Hepatitis C Screening and Treatment among Health Care Providers in Washington, DC.

Elimination of chronic hepatitis C (HCV) will require scaling up treatment, including possible HCV treatment by primary care providers. The District of Columbia (DC) has a substantial population living with untreated hepatitis C, and treatment expansion would benefit the resident population. The aim of this study was to assess the knowledge, attitudes, and behaviors of primary care providers and specialists related to hepatitis C screening and treatment. We conducted a prospective, online survey of physicians and nurse practitioners (n = 153) in DC on their knowledge, attitudes, and behaviors related to hepatitis C screening and treatment, as well as referral patterns, interest in learning, and preferred learning modalities. We compared responses by provider type. Key findings indicated that HCV screening and treatment knowledge was higher among specialty physicians as compared to primary care providers. The most common reported facilitators of HCV screening included a prompt in the electronic medical record (63%), patient education (57%), and support staff (41%). While 71% reported that HCV treatment was important in the community they serve, only 26% indicated that access to HCV specialist expertise and consultation was a major area of need. Additionally, 59% reported that they refer all HCV patients to specialists for treatment. Primary care providers in DC had moderate interest in learning how to treat chronic hepatitis C, but they need additional training. Patients are typically referred to gastroenterology, infectious diseases, and hepatology specialists who may have limited capacity to expand treatment.

Primary Care for Persons Who Inject Drugs.

More than 750,000 persons in the United States inject opioids, methamphetamine, cocaine, or ketamine, and that number is increasing because of the current opioid epidemic. Persons who inject drugs (PWID) are at higher risk of infectious and noninfectious skin, pulmonary, cardiac, neurologic, and other causes of morbidity and mortality. Nonjudgmental inquiries about current drug use can uncover information about readiness for addiction treatment and identify modifiable risk factors for complications of injection drug use. All PWID should be screened for human immunodeficiency virus infection, latent tuberculosis, and hepatitis B and C, and receive vaccinations for hepatitis A and B, tetanus, and pneumonia if indicated. Pre-exposure prophylaxis for human immunodeficiency virus infection should also be offered. Naloxone should be prescribed to those at risk of opioid overdose. Skin and soft tissue infections are the most common medical complication in PWID and the top reason for hospitalization in these patients. Signs of systemic infection require hospitalization, blood cultures, and a comprehensive history and physical examination to determine the source of infection. PWID have a higher incidence of community-acquired pneumonia and are at risk of other pulmonary complications, including opioid-associated pulmonary edema, asthma, and foreign body granulomatosis. Infectious endocarditis is the most common cardiac complication associated with injection drug use and more often involves the right-sided heart valves, which may not present with heart murmurs or peripheral signs and symptoms, in PWID. Injections increase the risk of osteomyelitis, as well as subdural and epidural abscesses.

Medical Students' Empathy for Vulnerable Groups: Results From a Survey and Reflective Writing Assignment.

PURPOSE: As medical education curricula increasingly acknowledge the contributions of the social determinants of health to individual health, new methods of engaging students in the care of vulnerable groups are needed. Empathy is one way to connect students with patients, but little is known about how to nurture students' empathy on behalf of populations. This study examined the relationship between individual and social empathy as groundwork for cultivating students' empathy for vulnerable groups. METHOD: In 2014-2015, first-year medical students completed the Social Empathy Index at the start and end of a two-semester population health course, and they completed a reflective writing assignment exploring the challenges of caring for vulnerable patients. Pre- and posttest mean survey scores were compared, and reflective writing assignments were analyzed for themes concerning social empathy. RESULTS: Data from 130 students were analyzed. Scores for the contextual understanding of systemic barriers domain increased significantly. There was a trend toward increased cumulative social empathy scores that did not reach statistical significance. Students' essays revealed three themes relating to individual empathy as the foundation for social empathy; civic and moral obligations; and the role of institutional practices in caring for vulnerable groups. CONCLUSIONS: This study extends understanding of empathy beyond care for the individual to include care for vulnerable groups. Thus, social empathy may function as a valuable concept in developing curricula to support students' commitment to care for the underserved. Educators first need to address the many barriers students cited that impede both individual and social empathy.

Recent trends in working with the private sector to improve basic healthcare: a review of evidence and interventions.

The private sector provides the majority of health care in Africa and Asia. A number of interventions have, for many years, applied different models of subsidy, support and engagement to address social and efficiency failures in private health care markets. We have conducted a review of these models, and the evidence in support of them, to better understand what interventions are currently common, and to what extent practice is based on evidence. Using established typologies, we examined five models of intervention with private markets for care: commodity social marketing, social franchising, contracting, accreditation and vouchers. We conducted a systematic review of both published and grey literature, identifying programmes large enough to be cited in publications, and studies of the listed intervention types. 343 studies were included in the review, including both published and grey literature. Three hundred and eighty programmes were identified, the earliest having begun operation in 1955. Commodity social marketing programmes were the most common intervention type, with 110 documented programmes operating for condoms alone at the highest period. Existing evidence shows that these models can improve access and utilization, and possibly quality, but for all programme types, the overall evidence base remains weak, with practice in private sector engagement consistently moving in advance of evidence. Future research should address key questions concerning the impact of interventions on the market as a whole, the distribution of benefits by socio-economic status, the potential for scale up and sustainability, cost-effectiveness compared to relevant alternatives and the risk of unintended consequences. Alongside better data, a stronger conceptual basis linking programme design and outcomes to context is also required.

Opioid Overdose Deaths in the City and County of San Francisco: Prevalence, Distribution, and Disparities.

Drug overdose is now the leading cause of unintentional death nationwide, driven by increased prescription opioid overdoses. To better understand urban opioid overdose deaths, this paper examines geographic, demographic, and clinical differences between heroin-related decedents and prescription opioid decedents in San Francisco from 2010 to 2012. During this time period, 331 individuals died from accidental overdose caused by opioids (310 involving prescription opioids and 31 involving heroin). Deaths most commonly involved methadone (45.9%), morphine (26.9%), and oxycodone (21.8%). Most deaths also involved other substances (74.9%), most commonly cocaine (35.3%), benzodiazepines (27.5%), antidepressants (22.7%), and alcohol (19.6%). Deaths were concentrated in a small, high-poverty, central area of San Francisco and disproportionately affected African-American individuals. Decedents in high-poverty areas were significantly more likely to die from methadone and cocaine, whereas individuals from more affluent areas were more likely die from oxycodone and benzodiazepines. Heroin decedents were more likely to be within a younger age demographic, die in public spaces, and have illicit substances rather than other prescription opioids. Overall, heroin overdose death, previously common in San Francisco, is now rare. Prescription opioid overdose has emerged as a significant concern, particularly among individuals in high-poverty areas. Deaths in poor and affluent regions involve different causative opioids and co-occurring substances.

Assessing the cost-effectiveness of treating chronic hepatitis C virus in people who inject drugs in Australia.

BACKGROUND AND AIM: To assess the cost-effectiveness of hepatitis C virus treatment with pegylated interferon alfa-2a and ribavirin in current and former people who inject drugs (PWID). METHODS: A decision analytic model simulated the lifetime costs and outcomes of four treatment options: early treatment with mild fibrosis, standard treatment with moderate fibrosis, late treatment with compensated cirrhosis, and no treatment. Treatment modalities were simulated across current, former, and never-injector cohorts of 1000 hypothetical patients with chronic hepatitis C virus. The main outcome measures were incremental costs ($AUD) per quality-adjusted life years (QALYs) gained, and incremental cost-effectiveness ratios (ICERs) were calculated for each cohort. RESULTS: Treatment of current PWID during mild fibrosis resulted in a discounted average gain of 1.60 QALYs (95% confidence interval 0.93-2.26) for an added cost of $12,723 ($11,153-$14,396) compared with no treatment, yielding an ICER of $7941 per QALY gained ($6347-$12,017). Former PWID gained 1.80 QALYs (1.29-2.33) for $10,441 ($8843-$12,074) for early treatment compared with no treatment, resulting in an ICER of $5808 per QALY gained ($5189-$6849). Never-injectors gained 2.33 QALYs (1.87-2.80) for $9290 ($7642-$10,912) compared with no treatment-an ICER of $3985 per QALY gained ($3896-$4080). Early treatment was more cost-effective than late treatment in all cohorts. CONCLUSIONS: Despite comorbidities, increased mortality, and reduced adherence, treatment of both current and former PWID is cost-effective. Our estimates fall below the unofficial Australian cost-effectiveness threshold of $AUD 50,000 per QALY for public subsidies. Scaling up treatment for PWID can be justified on purely economic grounds.

Where do poor women in developing countries give birth? A multi-country analysis of demographic and health survey data.

BACKGROUND: In 2008, over 300,000 women died during pregnancy or childbirth, mostly in poor countries. While there are proven interventions to make childbirth safer, there is uncertainty about the best way to deliver these at large scale. In particular, there is currently a debate about whether maternal deaths are more likely to be prevented by delivering effective interventions through scaled up facilities or via community-based services. To inform this debate, we examined delivery location and attendance and the reasons women report for giving birth at home. METHODOLOGY/PRINCIPAL FINDINGS: We conducted a secondary analysis of maternal delivery data from Demographic and Health Surveys in 48 developing countries from 2003 to the present. We stratified reported delivery locations by wealth quintile for each country and created weighted regional summaries. For sub-Saharan Africa (SSA), where death rates are highest, we conducted a subsample analysis of motivations for giving birth at home. In SSA, South Asia, and Southeast Asia, more than 70% of all births in the lowest two wealth quintiles occurred at home. In SSA, 54.1% of the richest women reported using public facilities compared with only 17.7% of the poorest women. Among home births in SSA, 56% in the poorest quintile were unattended while 41% were attended by a traditional birth attendant (TBA); 40% in the wealthiest quintile were unattended, while 33% were attended by a TBA. Seven per cent of the poorest women reported cost as a reason for not delivering in a facility, while 27% reported lack of access as a reason. The most common reason given by both the poorest and richest women for not delivering in a facility was that it was deemed "not necessary" by a household decision maker. Among the poorest women, "not necessary" was given as a reason by 68% of women whose births were unattended and by 66% of women whose births were attended. CONCLUSIONS: In developing countries, most poor women deliver at home. This suggests that, at least in the near term, efforts to reduce maternal deaths should prioritize community-based interventions aimed at making home births safer.
