A trial of implementation facilitation to increase timely admission to methadone treatment.

BACKGROUND: During the ongoing opioid epidemic, some Opioid Treatment Programs (OTPs) are unable to admit program applicants in a timely fashion. Interim methadone (IM) treatment (without routine counseling) is an effective approach to overcome this challenge when counseling capacity is inadequate to permit admissions within 14 days of request. It requires both federal and state approval and has been rarely utilized since its incorporation into the federal OTP regulations in 1993. METHODS: We evaluated the impact of Implementation Facilitation (IF) on OTPs providing timely admission to methadone treatment (i.e., within 14 days of request), adopting IM, and changing admissions procedures. IF included data collection on admission processes and an external facilitator who engaged OTP leadership, Local Champions through site visits, remote academic detailing, and feedback. Local Champions and State Opioid Treatment Authorities (SOTAs) participated in learning collaboratives. Using a modified stepped wedge design, six OTPs in four US states on the east and west coasts were randomly assigned to one of two clusters that staggered the timing of IF receipt. Study Phases included: Pre-Implementation, IF, and Sustainability. OTPs submitted data on treatment requests and admissions for 28 months (N = 3108 requests for treatment). RESULTS: Although none of the OTPs adopted IM, all six developed policies and procedures to enable its use. Some OTPs streamlined admissions processes prior to study launch and during the IF intervention. OTPs reduced admission delays over time, although there was substantial site heterogeneity. The IF Phase for the early cluster coincided with the onset of COVID-19, complicating the study. Rates of timely admission within 14 days of request were 56.2 % (Pre-Implementation), 55.8 % (IF), and 78.8 % (Sustainability). Compared to the Pre-Implementation Phase, the odds of timely admission were not significantly different during the IF Phase but significantly higher during the Sustainability Phase (OR = 2.35 [95 % CI = 1.34, 4.12]; p = 0.003). CONCLUSIONS: Committing to study participation and IF activities may have prompted some OTPs to change practices that improved timely admission. Attributing changes to IF should be done with caution considering study limitations. Data collection for the study spanned the COVID-19 pandemic, which complicates interpretation.

The Global Task Force for Chronic Pain in People with HIV (PWH): Developing a research agenda in an emerging field.

Chronic pain is a common comorbidity in people with HIV (PWH), with prevalence estimates of 25-85%. Research in this area is growing, but significant gaps remain. A Global Task Force of HIV experts was organized to brainstorm a scientific agenda and identify measurement domains critical to advancing research in this field. Experts were identified through literature searches and snowball sampling. Two online questionnaires were developed by Task Force members. Questionnaire 1 asked participants to identify knowledge gaps in the field of HIV and chronic pain and identify measurement domains in studies of chronic pain in PWH. Responses were ranked in order of importance in Questionnaire 2, which was followed by a group discussion. 29 experts completed Questionnaire 1, 25 completed Questionnaire 2, and 21 participated in the group. Many important clinical and research priorities emerged, including the need to examine etiologies of chronic pain in PWH. Pain-related measurement domains were discussed, with a primary focus on domains that could be assessed in a standardized manner across various cohorts that include PWH in different countries. We collaboratively identified clinical and research priorities, as well as gaps in standardization of measurement domains, that can be used to move the field forward.

Emergency department patients with untreated opioid use disorder: A comparison of those seeking versus not seeking referral to substance use treatment.

BACKGROUND Little is known regarding the sociodemographic and clinical characteristics of emergency department (ED) patients with untreated opioid use disorder (OUD) and the relationship of those characteristics with whether they were seeking a referral to substance use treatment at the time of their ED visit. METHODS Using data collected from 2/2017-1/2019 from participants enrolled in Project ED Health (CTN-0069), we conducted a cross-sectional analysis of patients with untreated moderate to severe OUD presenting to one of four EDs in Baltimore, New York City, Cincinnati, or Seattle. Sociodemographic and clinical correlates, and International Classification of Diseases Tenth Revision (ICD-10) diagnosis codes related to opioid withdrawal, injection-related infection, other substance use, overdose, and OUD of those seeking and not seeking a referral to substance use treatment on presentation were compared using univariate analyses. RESULTS Among 394 study participants, 15.2 % (60/394) came to the ED seeking a referral to substance use treatment. No differences in age, gender, education, health insurance status or housing stability were detected between those seeking and not seeking referral to substance use treatment. Those seeking a referral to substance use treatment were less likely to have urine toxicology testing positive for amphetamine [17 % (10/60) vs 31 % (104/334), p = 0.023] and methamphetamine [23 % (14/60) vs 40 % (132/334), p = 0.017] compared to those not seeking a referral. CONCLUSION Most patients with untreated OUD seen in the EDs were not seeking a referral to substance use treatment. Active identification, treatment initiation, and coding may improve ED efforts to address untreated OUD.

All-cause mortality among males living with and without HIV initiating long-term opioid therapy, and its association with opioid dose, opioid interruption and other factors.

BACKGROUND: While the relationship between long-term opioid therapy (LTOT) dose and overdose is well-established, LTOT's association with all-cause mortality is less understood, especially among people living with HIV (PLWH). There is also limited information regarding the association of LTOT cessation or interruption with mortality. METHODS: Among PLWH and matched uninfected male veterans in care, we identified those who initiated LTOT. Using time-updated cox regression, we examined the association between all-cause mortality, unnatural death, and overdose, and opioid use categorized as 1-20 (reference group), 21-50, 51-90, and ≥ 91 mg morphine equivalent daily dose (MEDD). RESULTS: There were 22,996 patients on LTOT, 6,578 (29 %) PLWH and 16,418 (71 %) uninfected. Among 5,222 (23 %) deaths, 12 % were unnatural deaths and 6 % overdoses. MEDD was associated with risk of all 3 outcomes; compared to patients on 1-20 mg MEDD, adjusted risk for all-cause mortality monotonically increased (Hazard Ratios (HR) [95 % CI] for 21-50 mg MEDD = 1.36 [1.21, 1.52], 51-90 mg MEDD = 2.06 [1.82, 2.35], and ≥ 91 mg MEDD = 3.03 [2.71, 3.39]). Similar results were seen in models stratified by HIV. LTOT interruption was also associated with all-cause, unnatural, and overdose mortality (HR [95 % CI] 2.30 [2.09, 2.53], 1.47 [1.13, 1.91] and 1.52 [1.04, 2.23], respectively). CONCLUSIONS: Among PLWH and uninfected patients on LTOT we observed a strong dose-response relationship with all 3 mortality outcomes. Opioid risk mitigation approaches should be expanded to address the potential effects of higher dose on all-cause mortality in addition to unnatural and overdose fatalities.

The impact of prescribed opioids on CD4 cell count recovery among HIV-infected patients newly initiating antiretroviral therapy.

OBJECTIVES: Certain prescribed opioids have immunosuppressive properties, yet their impact on clinically relevant outcomes, including antiretroviral therapy (ART) response among HIV-infected patients, remains understudied. METHODS: Using the Veterans Aging Cohort Study data, we conducted a longitudinal analysis of 4358 HIV-infected patients initiating ART between 2002 and 2010 and then followed them for 24 months. The primary independent variable was prescribed opioid duration, categorized using pharmacy data as none prescribed, short-term (< 90 days) and long-term (≥ 90 days). Outcomes included CD4 cell count over time. Analyses adjusted for demographics, comorbid conditions, ART type and year of initiation, and overall disease severity [ascertained with the Veterans Aging Cohort Study (VACS) Index]. Sensitivity analyses examined whether effects varied according to baseline CD4 cell count, achievement of viral load suppression, and opioid properties (i.e. dose and known immunosuppressive properties). RESULTS: Compared to those with none, patients with short-term opioids had a similar increase in CD4 cell count (mean rise per year: 74 vs. 68 cells/µL; P = 0.11), as did those with long-term prescribed opioids (mean rise per year: 74 vs. 75 cells/µL; P = 0.98). In sensitivity analysis, compared with no opioids, the effects of short-term prescribed opioids were statistically significant among those with a baseline CD4 cell count ≥ 500 cells/µL (mean rise per year: 52 cells/µL for no opioids vs. 20 cells/µL for short-term opioids; P = 0.04); findings were otherwise unchanged. CONCLUSIONS: Despite immunosuppressive properties intrinsic to opioids, prescribed opioids appeared to have no effect on CD4 cell counts over 24 months among HIV-infected patients initiating ART.

Impact of defined clinical population and missing data on temporal trends in HIV viral load estimation within a health care system.

OBJECTIVES: Community viral load (CVL) estimates vary based on analytic methods. We extended the CVL concept and used data from the Veterans Health Administration (VA) to determine trends in the health care system viral load (HSVL) and its sensitivity to varying definitions of the clinical population and assumptions regarding missing data. METHODS: We included HIV-infected patients in the Veterans Aging Cohort Study, 2000-2010, with at least one documented CD4 count, HIV-1 RNA or antiretroviral prescription (n = 37 318). We created 6-month intervals including patients with at least one visit in the past 2 years. We assessed temporal trends in clinical population size, patient clinical status and mean HSVL and explored the impact of varying definitions of the clinical population and assumptions about missing viral load. RESULTS: The clinical population size varied by definition, increasing from 16 000-19 000 patients in 2000 to 23 000-26 000 in 2010. The proportion of patients with suppressed HIV-1 RNA increased over time. Over 20% of patients had no viral load measured in a given interval or the past 2 years. Among patients with a current HIV-1 RNA, mean HSVL decreased from 97 800 HIV-1 RNA copies/mL in 2000 to 2000 copies/mL in 2010. When current HIV-1 RNA data were unavailable and the HSVL was recalculated using the last available HIV-1 RNA, HSVL decreased from 322 300 to 9900 copies/mL. HSVL was underestimated when using only current data in each interval. CONCLUSIONS: The CVL concept can be applied to a health care system, providing a measure of health care quality. Like CVL, HSVL estimates depend on definitions of the clinical population and assumptions about missing data.

Sexual partner notification of HIV infection among a National United States-based sample of HIV-infected men.

Limited data exist on whether sexual partner notification practices among HIV-infected men, particularly those who have sex with men (MSM), vary by HIV viral load. We examined factors associated with complete (all partners) versus incomplete partner notification in 760 HIV-infected individuals across the United States, 49 % of whom were MSM. Thirty-four percent reported incomplete partner notification. Incomplete partner notification was more likely among black men, MSM, and those reporting casual partners and non-condom use. Partner notification practices did not vary by HIV viral load except among those with casual partners in whom a detectable viral load was associated with incomplete partner notification. Increased sexual partner notification among HIV-infected men, especially MSM, is needed.

Breast tumor progression induced by loss of BTG2 expression is inhibited by targeted therapy with the ErbB/HER inhibitor lapatinib.

The B-cell translocation gene-2 (BTG2), a p53-inducible gene, is suppressed in mammary epithelial cells during gestation and lactation. In human breast cancer, decreased BTG2 expression correlates with high tumor grade and size, p53 status, blood and lymph vessel invasion, local and metastatic recurrence and decrease in overall survival, suggesting that suppression of BTG2 has a critical role in disease progression. To analyze the role of BTG2 in breast cancer progression, BTG2 expression was knocked down in mammary epithelial cells. Suppression of BTG2 enhances the motility of cells in vitro and tumor growth and metastasis in vivo. The effects of BTG2 knockdown are mediated through stabilization of the human epidermal growth factor receptor (HER) ligands neuregulin and epiregulin and activation of the HER2 and HER3 receptors, leading to elevated AKT phosphorylation. Suppression of HER activation using the tyrosine kinase inhibitor lapatinib abrogates the effects of BTG2 knockdown, including the increased cell migration observed in vitro and the enhancement of tumorigenesis and metastasis in vivo. These results link BTG2-dependent effects on tumor progression to ErbB receptor signaling, and raise the possibility that targeted inhibition of this pathway may be relevant in the treatment of breast cancers that have reduced BTG2 expression.

Patient and provider-reported symptoms in the post-cART era.

Prior research has consistently demonstrated that providers often under recognize symptoms. However, this research was limited by the different ways in which patients and providers were asked about the symptoms patients experience. We sought to (1) describe the prevalence of patient-reported symptoms in the post-cART era; (2) identify those patient-reported symptoms which are most strongly associated with health-related quality of life (HRQoL), hospitalization and mortality; and (3) determine whether primary providers recognize symptoms associated with HRQoL, hospitalization and mortality. We conducted a secondary analysis using baseline survey data from the Veterans Aging Cohort Study and determined which patient-reported symptoms correlated with clinical outcomes using regression analyses. Kappa scores were then calculated. HIV-infected patients suffer from a high burden of symptoms in the post-cART era. Nine out of 20 symptoms correlated with clinical outcomes. Providers universally under recognized symptoms and demonstrated poor agreement beyond chance when patient-report was used as the gold standard.
