Guideline-concordant management of opioid therapy among human immunodeficiency virus (HIV)-infected and uninfected veterans

Improving the Delivery of Chronic Opioid Therapy Among People Living With Human Immunodeficiency Virus: A Cluster Randomized Clinical Trial

BACKGROUND

Chronic pain is prevalent among people living with human immunodeficiency virus (PLWH); managing pain with chronic opioid therapy (COT) is common. Human immunodeficiency virus (HIV) providers often diverge from prescribing guidelines.

METHODS

This 2-arm, unblinded, cluster-randomized clinical trial assessed whether the Targeting Effective Analgesia in Clinics for HIV (TEACH) intervention improves guideline-concordant care compared to usual care for PLWH on COT. The trial was implemented from 2015 to 2018 with 12-month follow-up at safety-net hospital-based HIV clinics in Boston and Atlanta. We enrolled 41 providers and their 187 patients on COT. Prescribers were randomized 1:1 to either a 12-month intervention consisting of a nurse care manager with an interactive electronic registry, opioid education, academic detailing, and access to addiction specialists or a control condition consisting of usual care. Two primary outcomes were assessed through electronic medical records: ≥2 urine drug tests and any early COT refills by 12 months. Other outcomes included possible adverse consequences.

RESULTS

At 12 months, the TEACH intervention arm had higher odds of ≥2 urine drug tests than the usual care arm (71% vs 20%; adjusted odds ratio [AOR], 13.38 [95% confidence interval {CI}, 5.85-30.60]; P < .0001). We did not detect a statistically significant difference in early refills (22% vs 30%; AOR, 0.55 [95% CI, .26-1.15]; P = .11), pain severity (6.30 vs 5.76; adjusted mean difference, 0.10 [95% CI, -1.56 to 1.75]; P = .91), or HIV viral load suppression (86.9% vs 82.1%; AOR, 1.21 [95% CI, .47-3.09]; P = .69).

CONCLUSIONS

TEACH is a promising intervention to improve adherence to COT guidelines without evident adverse consequences.

Contribution of Behavioral Health Factors to Non-AIDS-Related Comorbidities: an Updated Review

PURPOSE OF REVIEW

We summarize recent literature on the contribution of substance use and depression to non-AIDS-related comorbidities. Discussion of recent randomized clinical trials and implementation research to curtail risk attributed to each behavioral health issue is provided.

RECENT FINDINGS

Smoking, unhealthy alcohol use, opioid use, and depression are common among PWH and individually contribute to increased risk for non-AIDS-related comorbidities. The concurrence of these conditions is notable, yet understudied, and provides opportunity for linked-screening and potential treatment of more than one behavioral health factor. Current results from randomized clinical trials are inconsistent. Investigating interventions to reduce the impact of these behavioral health conditions with a focus on implementation into clinical care is important. Non-AIDS-defining cancers, cardiovascular disease, liver disease, and diabetes are leading causes of morbidity in people with HIV. Behavioral health factors including substance use and mental health issues, often co-occurring, likely contribute to the excess risk of non-AIDS-related comorbidities.

High-dose prescribed opioids are associated with increased risk of heroin use among United States military veterans

Despite evidence linking increased risk of opioid use disorder with specific opioid-prescribing patterns, the relationship between these patterns and heroin use is less understood. This study aimed to determine whether dose and duration of opioid prescriptions predict subsequent heroin use in United States veterans. We analyzed data from 2002 to 2012 from the Veterans Aging Cohort Study, a prospective cohort study. We used inverse probability of censoring weighted Cox regression to examine the relationship between self-reported past year heroin use and 2 primary predictors: (1) prior receipt of a high-dose opioid prescription (≥90 mg morphine equivalent daily dose), and (2) prior receipt of a long-term opioid prescription (≥90 days). Heroin use was ascertained using most recent value of time-updated self-reported past year heroin use. Models were adjusted for HIV and hepatitis C virus infection status, sociodemographics, pain interference, posttraumatic stress disorder, depression, and use of marijuana, cocaine, methamphetamines, and unhealthy alcohol use. In the final model, prior receipt of a high-dose opioid prescription was associated with past year heroin use (adjusted hazard ratio use = 2.54, 95% confidence interval: 1.26-5.10), whereas long-term opioid receipt was not (adjusted hazard ratio = 1.09, 95% confidence interval: 0.75-1.57). Patients receiving high-dose opioid prescriptions should be monitored for heroin use. These findings support current national guidelines recommending against prescribing high-dose opioids for treating pain.

Trajectories of Self-Reported Opioid Use Among Patients With HIV Engaged in Care: Results From a National Cohort Study

BACKGROUND

No prior studies have characterized long-term patterns of opioid use regardless of source or reason for use among patients with HIV (PWH). We sought to identify trajectories of self-reported opioid use and their correlates among a national sample of PWH engaged in care.

SETTING

Veterans Aging Cohort Study, a prospective cohort including PWH receiving care at 8 US Veterans Health Administration (VA) sites.

METHODS

Between 2002 and 2018, we assessed past year opioid use frequency based on self-reported "prescription painkillers" and/or heroin use at baseline and follow-up. We used group-based trajectory models to identify opioid use trajectories and multinomial logistic regression to determine baseline factors independently associated with escalating opioid use compared to stable, infrequent use.

RESULTS

Among 3702 PWH, we identified 4 opioid use trajectories: (1) no lifetime use (25%); (2) stable, infrequent use (58%); (3) escalating use (7%); and (4) de-escalating use (11%). In bivariate analysis, anxiety; pain interference; prescribed opioids, benzodiazepines and gabapentinoids; and marijuana use were associated with escalating opioid group membership compared to stable, infrequent use. In multivariable analysis, illness severity, pain interference, receipt of prescribed benzodiazepine medications, and marijuana use were associated with escalating opioid group membership compared to stable, infrequent use.

CONCLUSION

Among PWH engaged in VA care, 1 in 15 reported escalating opioid use. Future research is needed to understand the impact of psychoactive medications and marijuana use on opioid use and whether enhanced uptake of evidence-based treatment of pain and psychiatric symptoms can prevent escalating use among PWH.

Opioid-Related Diagnoses and Concurrent Claims for HIV, HBV, or HCV among Medicare Beneficiaries, United States, 2015

Unsterile opioid injection increases risk for infection transmission, including HIV, hepatitis B virus (HBV), or hepatitis C virus (HCV). We assess prevalence of and risk factors associated with opioid overdose and infections with HIV, HBV, or HCV among Medicare beneficiaries with opioid-related fee-for-service claims during 2015. We conducted a cross-sectional analysis to estimate claims for opioid use and overdose and HIV, HBV, or HCV infections, using data from US Medicare fee-for-service claims. Beneficiaries with opioid-related claims had increased odds for HIV (2.3; 95% confidence interval (CI), 2.3–2.4), acute HBV (6.7; 95% CI, 6.3–7.1), chronic HBV (5.0; 95% CI, 4.7–5.4), acute HCV (9.6; 95% CI, 9.2–10.0), and chronic HCV (8.9; 95% CI, 8.7–9.1). Beneficiaries with opioid-related claims and for HIV, HBV, or HCV infection, respectively, had a 1.1–1.9-fold odds for having a claim for opioid overdose. Independent risk factors for opioid overdose and each selected infection outcome included age, sex, race/ethnicity, region, and residence in a high-vulnerability county. Having opioid-related claims and selected demographic attributes were independent, significant risk factors for having HIV, HBV, or HCV claims among US Medicare beneficiaries. These results might help guide interventions intended to reduce incidences of HIV, HCV, and HBV infections among beneficiaries with opioid-related claims.

Study protocol for the targeting effective analgesia in clinics for HIV (TEACH) study - a cluster randomized controlled trial and parallel cohort to increase guideline concordant care for long-term opioid therapy among people living with HIV

Background: People living with HIV (PLWH) frequently experience chronic pain and receive long-term opioid therapy (LTOT). Adherence to opioid prescribing guidelines among their providers is suboptimal. Objective: This paper describes the protocol of a cluster randomized trial, targeting effective analgesia in clinics for HIV (TEACH), which tested a collaborative care intervention to increase guideline-concordant care for LTOT among PLWH. Methods: HIV physicians and advanced practice providers (n = 41) were recruited from September 2015 to December 2016 from two HIV clinics in Boston and Atlanta. Patients receiving LTOT from participating providers were enrolled through a waiver of informed consent (n = 187). After baseline assessment, providers were randomized to the control group or the year-long TEACH intervention involving: (1) a nurse care manager and electronic registry to assist with patient management; (2) opioid education and academic detailing; and (3) facilitated access to addiction specialists. Randomization was stratified by site and LTOT patient volume. Primary outcomes (≥2 urine drug tests, early refills, provider satisfaction) were collected at 12 months. In parallel, PLWH receiving LTOT (n = 170) were recruited into a longitudinal cohort at both clinics and underwent baseline and 12-month assessments. Secondary outcomes were obtained through patient self-report among participants enrolled in both the cohort and the RCT (n = 117). Conclusions: TEACH will report the effects of an intervention on opioid prescribing for chronic pain on both provider and patient-level outcomes. The results may inform delivery of care for PLWH on LTOT for chronic pain at a time when opioid practices are being questioned in the US.

Lessons learnt from establishing a high dose opioid review clinic for people living with HIV

People living with HIV represent a unique aging population, living with a chronic condition associated with significant pain. A number take high dose, long-term opioids to manage moderate to severe chronic pain, presenting specific risks. This article highlights the size and impact of this problem and outlines the service objectives and set up of a specialist clinic to manage people living with HIV on high dose opioids, alongside its successes and learning points.

Racial disparities in discontinuation of long-term opioid therapy following illicit drug use among black and white patients

BACKGROUND

Among patients prescribed long-term opioid therapy (LTOT) for chronic pain, no study has yet examined how clinicians respond to evidence of illicit drug use and whether the decision to discontinue opioids is influenced by a patient's race.

METHODS

Among outpatients of black and white race initiating LTOT through the VA between 2000 and 2010, we reviewed electronic medical records to determine whether opioids were discontinued within 60 days of a positive urine drug test. Logistic regression was used to examine differences by race.

RESULTS

Among 15,366 patients of black (48.1%) or white (51.9%) race initiating LTOT from 2000 to 2010, 20.5% (25.5% of blacks vs. 15.8% of whites, P <. 001) received a urine drug test within the first 6 months of treatment; 13.8% tested positive for cannabis and 17.4% for cocaine. LTOT was discontinued in 11.4% of patients who tested positive for cannabis and in 13.1% of those who tested positive for cocaine. Among patients testing positive for cannabis, blacks were 2.1 times more likely than whites to have LTOT discontinued (adjusted odds ratio [AOR] 2.06, 95% confidence interval [CI] 1.04-4.08). Among patients testing positive for cocaine, blacks were 3.3 times more likely than whites to have LTOT discontinued (AOR 3.30, CI 1.28-8.53).

CONCLUSIONS

Among patients testing positive for illicit drug use while receiving LTOT, clinicians are substantially more likely to discontinue opioids when the patient is black. A more universal approach to administering and responding to urine drug testing is urgently needed.

The Effect of Substance Use Disorders on the Association Between Guideline-concordant Long-term Opioid Therapy and All-cause Mortality

OBJECTIVE

Patients with substance use disorders (SUDs) prescribed long-term opioid therapy (LtOT) are at risk for overdose and mortality. Prior research has shown that receipt of LtOT in accordance with clinical practice guidelines has the potential to mitigate these outcomes. Our objective was to determine whether the presence of a SUD modifies the association between guideline-concordant care and 1-year all-cause mortality among patients receiving LtOT for pain.

METHODS

Among HIV+ and HIV- patients initiating LtOT (≥90 days opioids) between 2000 and 2010 as part of the Veterans Aging Cohort Study, we used time-updated Cox regression and propensity-score matching to examine-stratified by SUD status-the association between 1-year all-cause mortality and 3 quality indicators derived from national opioid-prescribing guidelines. Specifically, we examined whether patients received psychotherapeutic cointerventions (≥2 outpatient mental health visits), benzodiazepine coprescriptions (≥7 days), and SUD treatment (≥1 inpatient day or outpatient visit). These indicators were among those found in a previous study to have a strong association with mortality.

RESULTS

Among 17,044 patients initiating LtOT, there were 1048 (6.1%) deaths during 1 year of follow-up. Receipt of psychotherapeutic cointerventions was associated with lower mortality in the overall sample and was more protective in patients with SUDs (adjusted hazard ratio [AHR] 0.43, 95% confidence interval [CI] 0.33-0.56 vs AHR 0.65, 95% CI 0.53-0.81; P for interaction = 0.002). Benzodiazepine coprescribing was associated with higher mortality in the overall sample (AHR 1.41, 95% CI 1.22-1.63), but we found no interaction by SUD status (P for interaction = 0.11). Among patients with SUDs, receipt of SUD treatment was associated with lower mortality (AHR 0.43, 95% CI 0.33-0.57).

CONCLUSIONS

For clinicians prescribing LtOT to patients with untreated SUDs, engaging patients with psychotherapeutic and SUD treatment services may reduce mortality. Clinicians should also avoid, when possible, prescribing opioids with benzodiazepines.

Brief Report: Longitudinal Opioid Use Among HIV-Infected Patients, 2000 to 2014

Longitudinal opioid prescription use is unknown among HIV-infected patients. Group-based trajectory modeling followed by multinomial logistic regression was used to identify distinct trajectories and their association with baseline characteristics among 1239 HIV-infected UNC CFAR HIV Clinical Cohort participants, 2000-2014. Three trajectories were identified: (1) 72% never/sporadic opioid use (referent group), (2) 11% episodic use (associated with female sex, depression, drug-related diagnoses, antiretroviral therapy use, and undetectable HIV RNA), and (3) 16% chronic use (associated with older age, female sex, and mental health diagnoses). Overall, opioid prescription decreased substantially with longer time in HIV care among both episodic and chronic users.

When human immunodeficiency virus (HIV) treatment goals conflict with guideline-based opioid prescribing: A qualitative study of HIV treatment providers

BACKGROUND

Human immunodeficiency virus (HIV)-infected patients have a high prevalence of chronic pain and opioid use, making HIV care a critical setting for improving the safety of opioid prescribing. Little is known about HIV treatment providers' perspectives about opioid prescribing to patients with chronic pain.

METHODS

The authors administered a questionnaire and conducted semistructured telephone interviews with 18 HIV treatment providers (infectious disease specialists, general internists, family medicine physicians, nurse practitioners, and physician assistants) in Bronx, NY. Open-ended interview questions focused on providers' experiences, beliefs, and attitudes about opioid prescribing and about the use of guideline-based opioid prescribing practices (conservative prescribing, and monitoring for and responding to misuse). Transcripts were thematically analyzed using a modified grounded theory approach.

RESULTS

Eighteen HIV treatment providers included 13 physicians, four nurse practitioners, and one physician assistant. They were 62% female, 56% white, and practiced as HIV treatment providers for a mean of 14.6 years. Most reported always or almost always using opioid treatment agreements (56%) and urine drug testing (61%) with their patients on long-term opioid therapy. HIV treatment providers tended to view opioid prescribing for chronic pain within the "HIV paradigm," a set of priorities and principles defined by three key themes: (1) primacy of HIV goals, (2) familiarity with substance use, and (3) the clinician as ally. The HIV paradigm sometimes supported, and sometimes conflicted with, guideline-based opioid prescribing practices. For HIV treatment providers, perceived alignment with the HIV paradigm determined whether and how guideline-based opioid prescribing practices were adopted. For example, the primacy of HIV goals superseded conservative opioid prescribing when providers prescribed opioids with the goal of retaining patients in HIV care.

CONCLUSION

These findings highlight unique factors in HIV care that influence adoption of guideline-based opioid prescribing practices. These factors should be considered in future research and initiatives to address opioid prescribing in HIV care.

Non-medical use of prescription opioids is associated with heroin initiation among US veterans: a prospective cohort study

AIMS

To estimate the influence of non-medical use of prescription opioids (NMUPO) on heroin initiation among US veterans receiving medical care.

DESIGN

Using a multivariable Cox regression model, we analyzed data from a prospective, multi-site, observational study of HIV-infected and an age/race/site-matched control group of HIV-uninfected veterans in care in the United States. Approximately annual behavioral assessments were conducted and contained self-reported measures of NMUPO and heroin use.

SETTING

Veterans Health Administration (VHA) infectious disease and primary care clinics in Atlanta, Baltimore, New York, Houston, Los Angeles, Pittsburgh and Washington, DC.

PARTICIPANTS

A total of 3396 HIV-infected and uninfected patients enrolled into the Veterans Aging Cohort Study who reported no life-time NMUPO or heroin use, had no opioid use disorder diagnoses at baseline and who were followed between 2002 and 2012.

MEASUREMENTS

The primary outcome measure was self-reported incident heroin use and the primary exposure of interest was new-onset NMUPO. Our final model was adjusted for socio-demographics, pain interference, prior diagnoses of post-traumatic stress disorder and/or depression and self-reported other substance use.

FINDINGS

Using a multivariable Cox regression model, we found that non-medical use of prescription opioids NMUPO was associated positively and independently with heroin initiation [adjusted hazard ratio (AHR) = 5.43, 95% confidence interval (CI) = 4.01, 7.35].

CONCLUSIONS

New-onset non-medical use of prescription opioids (NMUPO) is a strong risk factor for heroin initiation among HIV-infected and uninfected veterans in the United States who reported no previous history of NMUPO or illicit opioid use.

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.

The Association Between Receipt of Guideline-Concordant Long-Term Opioid Therapy and All-Cause Mortality

PURPOSE

For patients receiving long-term opioid therapy (LtOT), the impact of guideline-concordant care on important clinical outcomes--notably mortality--is largely unknown, even among patients with a high comorbidity and mortality burden (e.g., HIV-infected patients). Our objective was to determine the association between receipt of guideline-concordant LtOT and 1-year all-cause mortality.

METHODS

Among HIV-infected and uninfected patients initiating LtOT between 2000 and 2010 through the Department of Veterans Affairs, we used Cox regression with time-updated covariates and propensity-score matched analyses to examine the association between receipt of guideline-concordant care and 1-year all-cause mortality.

RESULTS

Of 17,044 patients initiating LtOT between 2000 and 2010, 1048 patients (6%) died during 1 year of follow-up. Patients receiving psychotherapeutic co-interventions (hazard ratio [HR] 0.62; 95% confidence interval [CI] 0.51-0.75; P < 0.001) or physical rehabilitative therapies (HR 0.81; 95% CI 0.67-0.98; P = 0.03) had a decreased risk of all-cause mortality compared to patients not receiving these services, whereas patients prescribed benzodiazepines concurrent with opioids had a higher risk of mortality (HR 1.39; 95% CI 1.12-1.66; P < 0.001). Among patients with a current substance use disorder (SUD), those receiving SUD treatment had a lower risk of mortality than untreated patients (HR 0.47; 95% CI 0.32-0.68; P = < 0.001). No association was found between all-cause mortality and primary care visits (HR 1.12; 95% CI 0.90-1.26; P = 0.32) or urine drug testing (HR 0.96; 95% CI 0.78-1.17; P = 0.67).

CONCLUSIONS

Providers should use caution in initiating LtOT in conjunction with benzodiazepines and untreated SUDs. Patients receiving LtOT may benefit from multi-modal treatment that addresses chronic pain and its associated comorbidities across multiple disciplines.

Barriers to guideline-concordant antibiotic use among inpatient physicians: A case vignette qualitative study

BACKGROUND

Greater adherence to antibiotic-prescribing guidelines may promote more judicious antibiotic use, which could benefit individual patients and society at large.

OBJECTIVE

To assess physician knowledge and acceptance of antibiotic-prescribing guidelines through the use of case vignettes.

DESIGN

We conducted semistructured interviews with 30 inpatient physicians. Participants were asked to respond to 3 hypothetical case vignettes: (1) a skin and soft tissue infection (SSTI), (2) suspected hospital-acquired pneumonia (HAP), and (3) asymptomatic bacteriuria (ASB). All participants received feedback according to guidelines from the Infectious Diseases Society of America (IDSA) and were asked to discuss their level of comfort with following these guidelines.

SETTING

Two acute care teaching hospitals for adult patients.

INTERVENTION

None.

MEASUREMENTS

Data from transcribed interviews were analyzed using emergent thematic analysis.

RESULTS

Participants were receptive to guidelines and believed they were useful. However, participants' responses to the case vignettes demonstrated that IDSA guideline recommendations were not routinely followed for SSTI, HAP, and ASB. We identified 3 barriers to guideline-concordant care: (1) physicians' lack of awareness of specific guideline recommendations; (2) tension between adhering to guidelines and the desire to individualize patient care; and (3) skepticism of certain guideline recommendations.

CONCLUSIONS

Case vignettes may be useful tools to assess physician knowledge and acceptance of antibiotic-prescribing guidelines. Using case vignettes, we identified 3 barriers to following IDSA guidelines. Efforts to improve guideline-concordant antibiotic prescribing should focus on reducing such barriers at the local level.

Factors Associated with Prescription of Opioids and Co-prescription of Sedating Medications in Individuals with HIV

Opioids are often prescribed for chronic pain, and opioid risks such as overdose and death are heightened when opioids are co-prescribed with other sedating medications. We investigated factors associated with chronic opioid prescription, alone and in combination with benzodiazepines and muscle relaxants, in a clinical cohort of individuals with HIV. We used multivariable logistic regression models to determine participant clinical and demographic characteristics that are associated with chronic prescription of opioids or chronic co-prescription of opioids with sedating medications. Among 1474 participants, chronic prescription of opioids occurred in 253 individuals (17.2 %), and chronic co-prescription occurred in 90 individuals (6.1 %). Age >50, public insurance as compared to private insurance, and symptoms of depression and anxiety were significantly associated with chronic opioid prescription and chronic co-prescription. Our findings raise concern that opioid prescription and co-prescription of sedating medications occurs disproportionately in patients for whom use is riskier.
