Associations between adverse childhood experiences, viral suppression, and quality of life among persons living with HIV in Washington state.

Adverse childhood experiences (ACEs) have been linked to numerous negative health outcomes in adulthood and have been recognized as a hurdle to participating in HIV care. However, few studies have examined the cumulative impact that different types of childhood trauma have on HIV care engagement and HIV outcomes. This study characterized the relationship between ACEs, viral suppression, and health-related quality of life (HRQOL) among persons living with HIV (PLWH). We used HIV surveillance data and self-reported information on ACEs and HRQOL from PLWH in Washington State from 2018-2020. Logistic regression was used to assess the relationship between the quantity and type of ACEs and viral suppression. We used Poisson regression to examine the relationship between ACEs and HRQOL as measured by unhealthy days. The majority of PLWH experienced ≥1 ACE (86.8%). ACEs were not significantly associated with the likelihood of viral suppression (OR ≥4 vs 0 ACEs: 0.49, 95% CI: 0.12-2.09), but ACEs were associated with more unhealthy days experienced in a 30-day period (RR ≥4 vs 0 ACEs: 3.19, 95% CI: 1.59-6.40). These findings provide support that trauma is common among PLWH, and efforts to address the impact of childhood trauma may work to improve quality of life.

Molecular Epidemiology of Individuals Experiencing Unstable Housing or Living Homeless at HIV Diagnosis: Analysis of HIV Surveillance Data in King County, Washington.

We examined patterns of genetic clustering among individuals diagnosed with HIV between 2010 and 2018 using data from King County, Washington's National HIV Surveillance System. Among 2,371 individuals newly diagnosed with HIV, 231 (10%) experienced unstable housing or were living homeless at the time of diagnosis. Among the 1,658 (70%) people with an available HIV-1 pol gene sequence, 1,071 (65%) were identified to be part of 296 genetic clusters. In our analysis, housing status was not associated with genetic clustering (OR 1.02; 95%CI:0.75,1.39). After adjusting for demographic and behavioral factors, people who were living homeless at HIV diagnosis had 35% lower odds of being identified as part of a genetic cluster (AOR 0.65; 95%CI:0.44,0.95) compared to people with stable housing. Our findings highlight that people experiencing unstable housing are disproportionately burdened by HIV, and that within this population in King County, being in a genetic cluster is predominantly associated with substance use.

Predictors of Failure to Reach Viral Suppression Within 1 Year After Human Immunodeficiency Virus Diagnosis: A Surveillance-Based Analysis.

BACKGROUND: Identifying factors associated with poor human immunodeficiency virus (HIV) care continuum outcomes in the first year after HIV diagnosis could guide care engagement efforts at the time of diagnosis. METHODS: We analyzed data from newly diagnosed persons living with HIV (PLWH) who received a partner services (PS) interview in King County, WA from January 1, 2013, to June 30, 2016. The outcome measure was failure to reach viral suppression, defined as the lack of an HIV RNA result <200 copies/mL reported to surveillance within one year after diagnosis. We constructed Kaplan-Meier curves of time to viral suppression and examined associations between viral suppression and demographic characteristics, substance use, housing status, and plan for HIV care. RESULTS: Among 549 individuals, 69 (13%) did not achieve viral suppression within 1 year. Failure to reach suppression was associated with having no plan for HIV care at the time of PS interview (n = 72; 13% of the total population; RR, 1.19; 95% CI, 1.04-1.36] and unstable housing (n = 81; 15% of the total population; [RR, 1.19; 95% CI, 1.05-1.35). Among persons with one of these two risk factors, 76% achieved viral suppression, compared with 91% of those with stable housing and a plan for care. Overall, 80% of persons who ultimately reached suppression did so by 7.3 months. CONCLUSIONS: Providing early support services to PLWH who have unstable housing or no plan for care at the time of HIV partner services interview and to those who do not reach viral suppression shortly after diagnosis could improve the HIV care continuum.

Outbreak of Human Immunodeficiency Virus Infection Among Heterosexual Persons Who Are Living Homeless and Inject Drugs - Seattle, Washington, 2018.

Although diagnoses of human immunodeficiency virus (HIV) infection among persons who inject drugs in the United States are declining, an HIV outbreak among such persons in rural Indiana demonstrated that population's vulnerability to HIV infection (1). In August 2018, Public Health-Seattle and King County (PHSKC) identified a cluster of cases of HIV infection among persons living homeless, most of whom injected drugs. Investigation identified 14 related cases diagnosed from February to mid-November 2018 among women who inject drugs and men who have sex with women (MSW) who inject drugs and their sex partners. All 14 persons were living homeless in an approximately 3-square-mile area and were part of a cluster of 23 cases diagnosed since 2008. Twenty-seven cases of HIV infection were diagnosed among women and MSW who inject drugs in King County during January 1-November 15, 2018, a 286% increase over the seven cases diagnosed in 2017. PHSKC has alerted medical and social service providers and the public about the outbreak, expanded HIV testing among persons who inject drugs or who are living homeless, and is working to increase the availability of clinical and prevention services in the geographic area of the outbreak. This outbreak highlights the vulnerability of persons who inject drugs, particularly those who also are living homeless, to outbreaks of HIV infection, even in areas with high levels of viral suppression and large syringe services programs (SSPs).

A Cluster Randomized Evaluation of a Health Department Data to Care Intervention Designed to Increase Engagement in HIV Care and Antiretroviral Use.

BACKGROUND: Many US health departments have implemented Data to Care interventions, which use HIV surveillance data to identify persons who are inadequately engaged in HIV medical care and assist them with care reengagement, but the effectiveness of this strategy is uncertain. METHODS: We conducted a stepped-wedge, cluster-randomized evaluation of a Data to Care intervention in King County, Washington, 2011 to 2014. Persons diagnosed as having HIV for at least 6 months were eligible based on 1 of 2 criteria: (1) viral load (VL) greater than 500 copies/mL and CD4 less than 350 cells/µL at the last report in the past 12 months or (2) no CD4 or VL reported to the health department for at least 12 months. The intervention included medical provider contact, patient contact, and a structured individual interview. Health department staff assisted patients with reengagement using health systems navigation, brief counseling, and referral to support services. We clustered all eligible cases in the county by the last known medical provider and randomized the order of clusters for intervention, creating contemporaneous intervention and control periods (cases in later clusters contributed person-time to the control period at the same time that cases in earlier clusters contributed person-time to the intervention period). We compared the time to viral suppression (VL <200 copies/mL) for individuals during intervention and control periods using a Cox proportional hazards model. RESULTS: We identified 997 persons (intention to treat [ITT]), 18% of whom had moved or died. Of the remaining 822 (modified ITT), 161 (20%) had an undetectable VL reported before contact and 164 (20%) completed the individual interview. The hazard ratio (HR) for time to viral suppression did not differ between the intervention and control periods in ITT (HR, 1.21 [95% confidence interval, 0.85-1.71]) or modified ITT (HR, 1.18 [95% confidence interval, 0.83-1.68]) analysis. CONCLUSIONS: The Data to Care intervention did not impact time to viral suppression.

Foreign-Born Individuals with HIV in King County, WA: A Glimpse of the Future of HIV?

To better understand country of birth-related shifts in the demography of people newly diagnosed with HIV infection, we compared demographic and clinical characteristics of foreign-born and U.S.-born residents of King County, WA diagnosed with HIV from 2006 to 2015. The proportion of cases that were foreign-born increased from 23 to 34% during this time. Most foreign-born cases were born in Africa (34%), Latin America (32%), Asia (22%), or Europe (7%). Latin Americans and Asians were similar to U.S.-born individuals by HIV risk factor and gender, while Africans were more likely to be female and less often men who have sex with men. In 2015, approximately 15% of cases presumptively newly diagnosed in King County were foreign-born individuals who self-reported a pre-immigration HIV diagnosis. Increases in foreign-born individuals previously diagnosed out of country may lead to inaccuracy in the count of new diagnoses, including an over-estimate of community-acquired HIV in King County.

Reconciling the evaluation of co-morbidities among HIV care patients in two large data systems: the Medical Monitoring Project and CFAR Network of Integrated Clinical Systems.

The estimated burden of chronic disease among people living with HIV (PLWH) varies considerably by data source, due to differences in case definitions, analytic approaches, and underlying patient populations. We evaluated the burden of diabetes (DM) and chronic kidney disease (CKD) in two large data systems that are commonly queried to evaluate health issues affecting HIV care patients: the Medical Monitoring Project (MMP), a nationally representative sample, and the Centers for AIDS Research Network of Integrated Clinical Systems (CNICS), a clinical cohort. In order to reconcile these two data sources, we addressed issues common to observational data, including selection bias, missing data, and development of case definitions. The overall adjusted estimated prevalence of DM and CKD in MMP was 12.7% and 7.6%, respectively, and the overall prevalence of DM and CKD in CNICS was 9.9% and 8.3%, respectively; prevalence estimates increased with age in both data sources. After reconciling the approach to analyzing MMP and CNICS data, sub-group specific prevalence estimates of DM and CKD was generally similar in both data sources. Both data sources suggest a considerable burden of disease among older adults in HIV care. MMP and CNICS can provide reliable data to monitor HIV co-morbidities in the US.

Emerging Regional and Racial Disparities in the Lifetime Risk of Human Immunodeficiency Virus Infection Among Men who Have Sex With Men: A Comparative Life Table Analysis in King County, WA and Mississippi.

BACKGROUND: Little is known about the lifetime risk of human immunodeficiency virus (HIV) diagnosis among US men who have sex with men (MSM), trends in risk and how risk varies between populations. METHODS: We used census and HIV surveillance data to construct life tables to estimate the cumulative risk of HIV diagnosis among cohorts of MSM born 1940 to 1994 in King County, Washington (KC) and Mississippi (MS). RESULTS: The cumulative risk of HIV diagnosis progressed in 3 phases. In phase 1, risk increased among MSM in successive cohorts born 1940 to 1964. Among men born 1955 to 1965 (the peak risk cohort), by age 55 years, 45% of white KC MSM, 65% of black KC MSM, 22% of white MS MSM, and 51% of black MS MSM had been diagnosed with HIV. In phase 2, men born 1965 to 1984, risk of diagnosis among KC MSM declined almost 60% relative to the peak risk cohort. A similar pattern of decline occurred in white MS MSM, with a somewhat smaller decline observed in black MS MSM. In phase 3, men born 1985 to 1994, the pattern of risk diverged. Among white KC MSM, black KC MSM, and white MS MSM, HIV risk increased slightly compared with men born 1975 to 1984, with 6%, 14%, and 2% diagnosed by age 27 years, respectively. Among black MS MSM born 1985 to 1994, HIV risk rose dramatically, with 35% HIV diagnosed by age 27 years. CONCLUSIONS: The lifetime risk of HIV diagnosis has substantially declined among MSM in KC and among white MSM in MS, but is rising dramatically among black MSM in MS.

Jail Booking as an Occasion for HIV Care Reengagement: A Surveillance-Based Study.

OBJECTIVES: To examine population and HIV care outcomes of people living with HIV/AIDS (PLWHA) at their first incarceration of 2014 in 2 county jails in King County, Washington. METHODS: Using HIV surveillance data linked with jail booking data, we examined demographic information, viral loads, CD4 counts, and incarceration details for the period prior to jail booking, during incarceration, and year following jail release. RESULTS: In 2014, 202 PLWHA were incarcerated, 51% of whom were virally nonsuppressed at booking. This population represented approximately 3% of all HIV-diagnosed persons and 7% of virally nonsuppressed persons in King County. Within a year of release, 62% were virally suppressed, compared with 79% of the general HIV-diagnosed population in King County. CONCLUSIONS: Incarcerated PLWHA are disproportionately virally nonsuppressed compared with nonincarcerated PLWHA up to a year after release from jail. Public Health Implications. Coordination of health information exchange between the health department and jails could enhance public health efforts to improve the HIV care continuum.

Integrating HIV Surveillance and Field Services: Data Quality and Care Continuum in King County, Washington, 2010-2015.

OBJECTIVES: To assess how integration of HIV surveillance and field services might influence surveillance data and linkage to care metrics. METHODS: We used HIV surveillance and field services data from King County, Washington, to assess potential impact of misclassification of prior diagnoses on numbers of new diagnoses. The relationship between partner services and linkage to care was evaluated with multivariable log-binomial regression models. RESULTS: Of the 2842 people who entered the King County HIV Surveillance System in 2010 to 2015, 52% were newly diagnosed, 41% had a confirmed prior diagnosis in another state, and 7% had an unconfirmed prior diagnosis. Twelve percent of those classified as newly diagnosed for purposes of national HIV surveillance self-reported a prior HIV diagnosis that was unconfirmed. Partner services recipients were more likely than nonrecipients to link to care within 30 days (adjusted risk ratio [RR] = 1.10; 95% confidence interval [CI] = 1.03, 1.18) and 90 days (adjusted RR = 1.07; 95% CI = 1.01, 1.14) of diagnosis. CONCLUSIONS: Integration of HIV surveillance, partner services, and care linkage efforts may improve the accuracy of HIV surveillance data and facilitate timely linkage to care.
