HIV Postexposure Prophylaxis Use Among Ontario Female Adolescent Sexual Assault Victims: A Prospective Analysis

Patient and Provider Decision Making About HIV Postexposure Prophylaxis Following Sexual Violence: A Qualitative Analysis

ABSTRACT

To explore patient and health care provider HIV postexposure prophylaxis (PEP) decision making following sexual assault, semistructured interviews regarding HIV PEP provision with 15 patients and 10 health care providers were conducted. A qualitative, descriptive, thematic analysis approach was used. Four themes were derived: (a) medical concerns; (b) emotional, trauma, and support factors; (c) daily medication management; and (d) ensuring access to HIV PEP. How participants described these themes and the importance placed on factors within each theme varied between the two groups. Altering provider communication so that HIV PEP discussions better align with patient decision-making factors (e.g., trauma and ability to take in information, how to manage side effects) could facilitate improvement in HIV PEP decision making following sexual assault for patients. High-level policy changes would improve HIV PEP access for sexual assault patients without necessitating the extraordinary efforts individual providers currently undertake.

Adolescent Female Victims of Sexual Violence: Analysis of Loss of Follow-up after Emergency Care and Outpatient Follow-up

OBJECTIVE

 To assess the loss to follow-up after emergency care and during 6-months of outpatient follow-up, and the associated variables, among adolescent sexual violence survivors.

METHODS

 This is a retrospective study with review of the medical records of 521 females, aged 10 to 18 years, who received emergency care in a referral service in São Paulo, Brazil. The variables were sociodemographic; personal history; characteristics of abuse, disclosure, and reactions triggered after abuse (physical and mental disorders as well as social changes), psychotropic prescription needs, and moment of abandonment: after emergency care and before completing 6 months of outpatient follow-up. To compare groups of patients lost to follow-up at each time point, we used the Chi-square and Fisher exact tests followed by multiple logistic regression with stepwise criterion for selection of associated variables. We calculated the odds ratio with confidence interval (OR, CI 95%). The level of significance adopted was 5%.

RESULTS

 A total of 249/521 (47.7%) adolescents discontinued follow-up, 184 (35.3%) after emergency care and 65 (12.4%) before completing outpatient follow-up. The variables of living with a partner (OR = 5.94 [CI 95%; 2.49-14.20]); not having a religion (OR = 2.38 [CI 95%;1.29-4.38)]), having a Catholic religion [OR =  2.11 (CI 95%; 1.17-3.78)]; and not disclosing the abuse [OR = 2.07 (CI 95%; 1.25-3.44)] were associated with loss to follow-up after emergency care. Not needing mental disorder care (OR = 2.72 [CI 95%; 1.36-5.46]) or social support (OR = 2.33 [CI 95%; 1.09-4.99]) were directly associated with loss to outpatient follow-up.

CONCLUSION

 Measures to improve adherence to follow-up should be aimed at adolescents who live with a partner and those who do not tell anyone about the violence.

Factors Impacting HIV Postexposure Prophylaxis Among Sexually Assaulted Patients Presenting to Two Urban Emergency Departments

INTRODUCTION

Sexually assaulted patients who seek care in emergency departments are often recommended for nonoccupational HIV postexposure prophylaxis treatment. HIV postexposure prophylaxis is an effective method in preventing HIV transmission if the treatment is administered promptly and if a full 28-day course is completed. However, research has shown that only a fraction of patients who start the treatment will complete a 28-day course. Research is needed to explore factors that may be associated with compliance to postexposure prophylaxis so that interventions can be designed to address the factors that put patients at risk for noncompletion.

METHODS

A retrospective chart review was conducted examining 246 medical records of sexually assaulted female patients who presented to one of two urban hospitals. A number of patient and event-related factors were examined to determine whether they were associated with HIV postexposure prophylaxis adherence among patients presenting at an emergency room after a sexual assault.

RESULTS

Results revealed that five factors showed significant associations with sexually assaulted female patients completing HIV postexposure prophylaxis treatment. These factors include educational level, employment, health insurance, vaginal injuries, and tongue-mouth assaults.

IMPLICATIONS FOR PRACTICE

The results of this study represent a starting point from which to inform the development of targeted interventions such that those most at risk for nonadherence can receive additional support or services to improve HIV postexposure prophylaxis adherence.

Sexually Transmitted Infections Treatment Guidelines, 2021

These guidelines for the treatment of persons who have or are at risk for sexually transmitted infections (STIs) were updated by CDC after consultation with professionals knowledgeable in the field of STIs who met in Atlanta, Georgia, June 11-14, 2019. The information in this report updates the 2015 guidelines. These guidelines discuss 1) updated recommendations for treatment of Neisseria gonorrhoeae, Chlamydia trachomatis, and Trichomonas vaginalis; 2) addition of metronidazole to the recommended treatment regimen for pelvic inflammatory disease; 3) alternative treatment options for bacterial vaginosis; 4) management of Mycoplasma genitalium; 5) human papillomavirus vaccine recommendations and counseling messages; 6) expanded risk factors for syphilis testing among pregnant women; 7) one-time testing for hepatitis C infection; 8) evaluation of men who have sex with men after sexual assault; and 9) two-step testing for serologic diagnosis of genital herpes simplex virus. Physicians and other health care providers can use these guidelines to assist in prevention and treatment of STIs.

Adherence to HIV post-exposure prophylaxis for children/adolescents who have been sexually assaulted: A systematic review of barriers, enablers, and interventions

Post-exposure prophylaxis (PEP) is a key intervention for preventing HIV acquisition, including following sexual assault. However, uptake and completion rates for HIV PEP are lowest following sexual assault, with only 40% reporting completing the 28-day course. We undertook a systematic review to assess barriers and enablers to adherence to PEP in children and adolescents following sexual assault and identify potential interventions. Five databases and one conference abstract library were searched using adapted search strategies to identify quantitative and qualitative studies reporting patient-reported barriers and enablers to PEP and randomized trials assessing interventions to improve PEP adherence and completion rates. All searches were conducted up to October 2016; the search was updated in PubMed up to 31 July 2018. 14 studies reported barriers and enablers to PEP adherence. The most commonly cited patient/caregiver reported barriers to PEP adherence/completion included side effects, forgetting, stigma/blame, being busy, poor knowledge, and mental health problems. The most commonly reported factors associated with PEP adherence/completion (reported across 7 studies) included health provider encouragement to take PEP (type of encouragement not described), perpetrator known to be HIV-positive, monetary support for transport, the victim of assault attending counseling, being reminded by family/peers to take PEP, and "one-stop" services offering both HIV testing and PEP at initial consultation. Three randomized trials provided limited evidence supporting the potential benefit of enhanced adherence support for HIV PEP; however, data for children were lacking. Despite low completion rates, there is limited research into causes of and interventions to improve adherence to PEP following sexual assault, and no direct evidence for children.

"Reclaiming Control" Patient Acceptance and Adherence to HIV Post-Exposure Prophylaxis Following Sexual Assault

Sexual assault is an irrefutable trauma; an insult to the autonomy of the person forced into sexual acts. Sexual assault sequelae range from physical injury and acute traumatic stress, to pregnancy and sexually transmitted infections, including human immunodeficiency virus (HIV). HIV post-exposure prophylaxis (HIV PEP) following sexual assault may decrease the likelihood of HIV transmission. Many patients seeking healthcare post-sexual assault either do not initiate HIV PEP or do not complete the 28-day medication regimen. In this qualitative interpretive description, we interviewed sexual assault patients (N=11) about HIV PEP discussions/reactions, attitudes and understanding related to HIV and PEP, and barriers and facilitators of HIV PEP acceptance and adherence. Participants described a process of losing and reclaiming control throughout post-assault care and follow-up; and how this affected HIV PEP-related decision-making. Most HIV PEP decisions were described as a process of reclaiming control over one outcome while simultaneously losing control of another.

Post-exposure prophylaxis for HIV infection in sexual assault victims

OBJECTIVES

Sexual assault (SA) is recognized as a public health problem of epidemic proportions. Guidelines recommend the administration of post-exposure prophylaxis (PEP) after an SA. However, few data are available about the feasibility of this strategy, and this study was conducted to assess this.

METHODS

We conducted a retrospective, longitudinal, observational study in SA victims attending the Hospital Clinic in Barcelona from 2006 to 2015. A total of 1695 SA victims attended the emergency room (ER), of whom 883 met the PEP criteria. Five follow-up visits were scheduled at days 1, 10, 28, 90 and 180 in the out-patient clinic. The primary endpoint was PEP completion rate at day 28. Secondary endpoints were loss to follow-up, treatment discontinuation, occurrence of adverse events (AEs) and rate of seroconversion.

RESULTS

The median age of participants was 25 years [interquartile range (IQR) 21-33 years] and 93% were female. The median interval between exposure and presentation at the ER was 13 h (IQR 6-24 h). The level of risk was appreciable in 47% (n = 466) of individuals. Of 883 patients receiving PEP, 631 lived in Catalonia. In this group, the PEP completion rate at day 28 was 29% (n = 183). The follow-up rate was 63% (n = 400) and 38% (n = 241) at days 1 and 28, respectively. Treatment discontinuation was present in 58 (15%) of 400 patients who attended at least the day 1 visit, the main reason being AEs (n = 35; 60%). AEs were reported in 226 (56%) patients, and were mainly gastrointestinal (n = 196; 49%). Only 211 (33%) patients returned for HIV testing at day 90. A single seroconversion was observed in a men who have sex with men (MSM) patient at day 120.

CONCLUSIONS

Follow-up and compliance rates in SA victims were poor. In addition, > 50% of the patients experienced AEs, which were the main reason for PEP interruption. Strategies to increase follow-up testing and new better tolerated drug regimens must be investigated to address these issues.

Pediatric Considerations for Postexposure Human Immunodeficiency Virus Prophylaxis

Exposures that carry risk of transmission of blood-borne disease are rare in pediatrics, but expose patients and families to great anxiety. Specialists in pediatric infectious diseases are often asked about initial antimicrobial prophylaxis in these cases. Guidelines for nonoccupational postexposure prophylaxis for human immunodeficiency virus have evolved as new formulations and medications become available and greater experience obtained in assessing relative risks of different exposures and relative costs and benefits for different interventions. This article discusses the evidence behind recent updates to Centers for Disease Control and Prevention guidelines for nonoccupational postexposure prophylaxis for human immunodeficiency virus, focusing on application in the pediatric population.

Exploring Receipt of HIV PEP Counseling Among Women Sexually Assaulted by an Intimate Partner

Among 136 women sexually assaulted by a current or former male intimate partner presenting to hospital-based violence treatment centers, 58 (42.6%) received HIV post-exposure prophylaxis (HIV PEP) counseling by a specially trained sexual assault nurse. We identified factors that were associated with receipt of HIV PEP counseling. Those who received counseling were more likely to have been younger than 25 years of age, single, a student, vaginally penetrated, and have received various other services (e.g., STI prophylaxis). They were less likely to have been unemployed. Hospital-based violence treatment centers need to be aware that not all women sexually assaulted by an intimate partner will have the same risk of acquisition of HIV and care needs.

Nonoccupational Postexposure Human Immunodeficiency Virus Prophylaxis: Acceptance Following Sexual Assault

BACKGROUND

Nonoccupational postexposure prophylaxis (nPEP) for HIV following sexual assault may decrease the likelihood of HIV transmission.

OBJECTIVE

The purpose of this exploratory chart review study was to examine factors associated with patients accepting post-sexual assault nPEP at three forensic nurse examiner programs in urban settings.

METHODS

Forensic nursing charts of patients presenting for acute sexual assault care were reviewed as part of a mixed-methods study.

RESULTS

Patients assaulted by more than one or an unknown number of assailants were over 12 times more likely to accept the offer of nPEP (adjusted odds ratio [aOR] = 12.66, 95% CI [2.77, 57.82]). In cases where no condom was used (aOR = 8.57, 95% CI [1.59, 46.10]) or when any injury to the anus or genitalia was noted (aOR = 4.10, 95% CI [1.57, 10.75]), patients were more likely to accept nPEP. Patients with any injury to the face or head were less likely to initiate nPEP (aOR = 0.32, 95% CI [0.11, 0.97]).

DISCUSSION

This study is an important first step in understanding factors associated with nPEP acceptance after sexual assault.

Antiretroviral chemoprophylaxis in children and adolescents victims of rape in Abidjan

OBJECTIVE

We described the use of antiretroviral drugs to prevent HIV transmission among children and adolescents victims of rape in Abidjan (Ivory Coast).

MATERIALS AND METHOD

We conducted a retrospective and descriptive study on children (0-9 years) and adolescents (10-19 years) victims of rape between 2000 and 2013. We analyzed the patients' socio-demographic characteristics and the modality of the chemoprophylaxis.

RESULTS

We included 10 children and 89 adolescents in the study. The median age was 16 years old (3-19 years). The median time to consultation was 23.5 hours (5-152 hours). The antiretroviral chemoprophylaxis was administered to 92 patients (93%). No HIV and HBV seroconversion was observed after a 3-month follow-up.

CONCLUSION

A better management of rape victims is required in Abidjan.

Prevention of human immunodeficiency virus and AIDS: postexposure prophylaxis (including health care workers)

Postexposure prophylaxis (PEP), which is designed to prevent human immunodeficiency virus (HIV) infection after an exposure, is one of several strategies for HIV prevention. PEP was first used after occupational HIV exposures in the late 1980s, with the Centers for Disease Control and Prevention issuing the first set of guidelines that included considerations regarding the use of antiretroviral agents for PEP after occupational HIV exposures in 1990. Use of PEP has been extended to nonoccupational exposures, including after sexual contact or injection-drug use. This article provides a rationale for PEP, assessment of the need for PEP, and details of its implementation.

Male victims of adult sexual assault: a descriptive study of survivors' use of sexual assault treatment services

This descriptive study aims to provide new information about the services used by sexually assaulted men and adolescent boys presenting to specialized hospital-based sexual assault programs and further insight into the factors that may be associated with their victimization. Information was collected from 38 male clients aged 12+ presenting to 29 sexual assault treatment centers in Ontario, Canada over 12 months. Variables were examined across 6 domains: time to presentation, client sociodemographics, assailant characteristics, assault characteristics, physical health consequences, and service delivery and utilization. A substantial minority of participants reported vulnerabilities such as young age; being Aboriginal; being transgendered, unemployed and/or on disability; working in the sex trade; and living on the streets, in a rehabilitative center, or in a correctional facility. Almost one-third identified or were documented as having a disability and, for most of these victims, it was either psychiatric in nature or developmental delay. All participants accepted at least one service offered; 86% used five or more services, most commonly those related to health care on-site such as crisis counseling, treatment of injuries, and referral for follow-up care for supportive counseling, injury redocumentation, and testing for sexually transmitted infections. These findings reveal that male clients' uptake of specialized sexual assault services is significant and it is, therefore, important to provide access to a comprehensive range of psychological, medical, and forensic treatment options and referrals to other community services for ongoing support. Implications for future research and practice are discussed.

Factors associated with the sexual assault of students: an exploratory study of victims treated at hospital-based sexual assault treatment centers

Research suggests that students experience high levels of sexual assault, but studies addressing how they differ in their experiences from other sexual assault victims are virtually nonexistent. To address this gap, information was collected from consecutive individuals, aged 16 years or older, presenting to one of 7 hospital-based sexual assault treatment centers in Ontario from 2005 to 2007. Of the 882 victims seen during the study period, 32% were students. Relative to other sexual assault victims, students were more likely to be aged 16 to 18 years and 19 to 24 years versus 25 years and older. They were more likely to be living alone, with family of origin, a partner or spouse, or a nonrelative than on the street or in a shelter or institution. They were also more likely to report having consumed over-the-counter medication in the 72 hours prior to examination. Student victims were less likely than nonstudent victims to report having a disability and having used street drugs. Implications for research, education, and practice are discussed.

Sexual assault injuries and increased risk of HIV transmission

Sexual assault and HIV are coexisting public health problems. Sexual assault may increase HIV transmission risk through diverse mechanisms, such as infliction of anal, oral, and genital injuries by penile, digital, or object penetration, extragenital trauma, concurrent sexually transmitted infections, condom use, and whether the perpetrator was circumcised.

Sustainability of an HIV PEP Program for Sexual Assault Survivors: "Lessons Learned" from Health Care Providers

This study explored challenges to continuing an HIV post-exposure prophylaxis (PEP) program of care provided to sexual assault survivors in the province of Ontario, Canada. Data were collected as part of an implementation and evaluation of a universal offering of HIV PEP (known as the HIV PEP Program) at 24 of 34 provincial hospital-based sexual assault treatment centres. Experienced health care providers were surveyed (n = 132) and interviewed in four focus groups (n = 26) about their perceptions of what, if any, factors threatened their ability to maintain the HIV PEP Program. All focus groups were audio-recorded and the recordings transcribed. The transcriptions and open-ended survey responses were analyzed using content analysis. Administrator, nurse, physician, social worker, and pharmacist respondents perceived important barriers to sustainability of the HIV PEP Program. Eight constructs were identified within four broad themes: resources (inadequate funds, overworked and unacknowledged staff), expertise (insufficient external supports, insufficiently trained and knowledgeable staff), commitment (lack of institutional support, physician resistance to offering HIV PEP), and accommodation (lack of flexibility in addressing specific client and community needs, inaccessibility and lack of clarity of tools). We discuss the implications of these findings and the actions that were taken to address the challenges.

Addressing the intersections of violence and HIV/AIDS: a qualitative study of service providers

This article examines what measures health care and social service providers take to address intersections between various forms of violence and HIV/AIDS in the delivery of services to their clients/patients. We operated within an organizationallinteractional uncertainty theoretical framework and analyzed qualitative interview data from 30 providers offering services related to violence or HIV/AIDS in the San Francisco Bay Area. We found that providers used several strategies to mitigate crossover risk, but they enacted these measures on a case-by-case basis and tended not to follow a dedicated and complete protocol with every client/patient. We also identify nine factors that affected providers' capacity to discern and effectively address violence-HIV/AIDS intersections, present providers' descriptions of their needs in terms of addressing crossover risk, and discuss implications for interventions.

Sexual abuse and sexually transmitted infections in children and adolescents

PURPOSE OF REVIEW

Sexual abuse is unfortunately common in the United States. The presence of a sexually transmitted infection in a child or adolescent should prompt an evaluation to exclude sexual abuse.

RECENT FINDINGS

The present article reviews the demographics of sexual abuse, the prevalence of specific sexually transmitted infections, such as Neisseria gonorrhoeae, Chlamydia trachomatis, HIV, human papillomavirus (HPV) and herpes simplex virus (HSV) and which children and adolescents are at highest risk for contracting such infections. The use of nonculture methods, such as nucleic acid amplification tests (NAATs), to evaluate prepubertal children for N. gonorrhoeae or C. trachomatis, and the use of HIV postexposure prophylaxis are discussed.

SUMMARY

Any child or adolescent with a sexually transmitted infection should be evaluated for sexual abuse. Specific infections in prepubertal children, such as Neisseria gonorrhoeae or Chlamydia trachomatis, are due to abusive contact and should be reported to Child Protective Services. As the modes of transmission of anogenital infections with HPV and HSV are unclear, an evaluation for sexual abuse should be done. Although transmission of HIV after sexual abuse is rare, HIV postexposure prophylaxis must be administered in a timely fashion, and adequate outpatient support provided to facilitate compliance and follow-up.
