The impact of buprenorphine on treatment of opioid dependence in a Medicaid population: Recent service utilization trends in the use of buprenorphine and methadone

BACKGROUND Buprenorphine provides an important option for individuals with opioid dependence who are unwilling or unable to attend a licensed methadone opioid agonist treatment program to receive opioid agonist therapy (OAT). Little empirical information is available, however, about the extent to which buprenorphine has increased the percentage of opioid dependent individuals receiving OAT, nor to what extent buprenorphine is being used in office based settings. METHODS Using administrative data from the largest Medicaid managed behavioral health organization in a large mid-Atlantic state, we used multivariate regression to examine rates and predictors of opioid agonist use and treatment setting for 14,386 new opioid dependence treatment episodes during 2007-2009. RESULTS Despite an increase in the use of buprenorphine, the percentage of new treatment episodes involving OAT is unchanged due to a decrease in the percentage of episodes involving methadone. Use of buprenorphine was significantly more common in rural communities, and 64% of buprenorphine use was in office-based settings. CONCLUSION Buprenorphine use has increased in recent years, with the greatest use in rural communities and in office based settings. However, the percentage of new opioid dependence treatment episodes involving an opioid agonist is unchanged, suggesting the need for further efforts to increase buprenorphine use among urban populations.

Supply of buprenorphine waivered physicians: The influence of state policies

Buprenorphine, an effective opioid use disorder treatment, can be prescribed only by buprenorphine-waivered physicians. We calculated the number of buprenorphine-waivered physicians/100,000 county residents using 2008-11 Buprenorphine Waiver Notification System data, and used multivariate regression models to predict number of buprenorphine-waivered physicians/100,000 residents in a county as a function of county characteristics, state policies and efforts to promote buprenorphine use. In 2011, 43% of US counties had no buprenorphine-waivered physicians and 7% had 20 or more waivered physicians. Medicaid funding, opioid overdose deaths, and specific state guidance for office-based buprenorphine use were associated with more buprenorphine-waivered physicians, while encouraging methadone programs to promote buprenorphine use had no impact. Our findings provide important empirical information to individuals seeking to identify effective approaches to increase the number of physicians able to prescribe buprenorphine.

Applying a Natural Language Processing Tool to Electronic Health Records to Assess Performance on Colonoscopy Quality Measures

BACKGROUND Gastroenterology specialty societies have advocated that providers routinely assess their performance on colonoscopy quality measures. Such routine measurement has been hampered by the costs and time required to manually review colonoscopy and pathology reports. Natural language processing (NLP) is a field of computer science in which programs are trained to extract relevant information from text reports in an automated fashion. OBJECTIVE To demonstrate the efficiency and potential of NLP-based colonoscopy quality measurement. DESIGN In a cross-sectional study design, we used a previously validated NLP program to analyze colonoscopy reports and associated pathology notes. The resulting data were used to generate provider performance on colonoscopy quality measures. SETTING Nine hospitals in the University of Pittsburgh Medical Center health care system. PATIENTS Study sample consisted of the 24,157 colonoscopy reports and associated pathology reports from 2008 to 2009. MAIN OUTCOME MEASUREMENTS Provider performance on 7 quality measures. RESULTS Performance on the colonoscopy quality measures was generally poor, and there was a wide range of performance. For example, across hospitals, the adequacy of preparation was noted overall in only 45.7% of procedures (range 14.6%-86.1% across 9 hospitals), cecal landmarks were documented in 62.7% of procedures (range 11.6%-90.0%), and the adenoma detection rate was 25.2% (range 14.9%-33.9%). LIMITATIONS Our quality assessment was limited to a single health care system in western Pennsylvania. CONCLUSIONS Our study illustrates how NLP can mine free-text data in electronic records to measure and report on the quality of care. Even within a single academic hospital system, there is considerable variation in the performance on colonoscopy quality measures, demonstrating the need for better methods to regularly and efficiently assess quality.

Comparing VA and Non-VA Quality of Care: A Systematic Review

BackgroundThe Veterans Affairs (VA) health care system aims to provide high-quality medical care to veterans in the USA, but the quality of VA care has recently drawn the concern of Congress. The objective of this study was to systematically review published evidence examining the quality of care provided at VA health care facilities compared to quality of care in other facilities and systems.MethodsBuilding on the search strategy and results of a prior systematic review, we searched MEDLINE (from January 1, 2005, to January 1, 2015) to identify relevant articles on the quality of care at VA facilities compared to non-VA facilities. Articles from the prior systematic review published from 2005 and onward were also included and re-abstracted. Studies were classified, analyzed, and summarized by the Institute of Medicine’s quality dimensions.ResultsSixty-nine articles were identified (including 31 articles from the prior systematic review and 38 new articles) that address one or more Institute of Medicine quality dimensions: safety (34 articles), effectiveness (24 articles), efficiency (9 articles), patient-centeredness (5 articles), equity (4 articles), and timeliness (1 article). Studies of safety and effectiveness indicated generally better or equal performance, with some exceptions. Too few articles related to timeliness, equity, efficiency, and patient-centeredness were found from which to reliably draw conclusions about VA care related to these dimensions.DiscussionThe VA often (but not always) performs better than or similarly to other systems of care with regard to the safety and effectiveness of care. Additional studies of quality of care in the VA are needed on all aspects of quality, but particularly with regard to timeliness, equity, efficiency, and patient-centeredness.

The Affordable Care Act: An Opportunity for Improving Care for Substance Use Disorders?

The Patient Protection and Affordable Care Act (ACA) will greatly increase coverage for treatment of substance use disorders. To realize the benefits of this opportunity, it is critical to develop reliable, valid, and feasible measures of quality to ensure that treatment is accessible and of high quality. The authors review the availability of current quality measures for substance use disorder treatment and conclude there is a pressing need for development, validation, and use of quality measures. They provide recommendations for research and policy changes to increase the likelihood that patients, families, and society benefit from the increased coverage provided by the ACA.

Barriers to Engaging Service Members in Mental Health Care Within the U.S. Military Health System

OBJECTIVE Over the past decade, there has been growing recognition of the mental health consequences associated with deployment and service by military service personnel. This study examined potential barriers to mental health care faced by members of the military in accessing needed services. METHODS This qualitative study of stakeholders was conducted across six large military installations, encompassing 18 Army primary care clinics, within the context of a large randomized controlled trial. Stakeholders included patients recruited for the study (N=38), health care providers working within site clinics (N=31), and the care managers employed to implement the intervention protocol (N=7). RESULTS Issues raised across stakeholder groups fell into two main categories: structural factors associated with the Army medical system and institutional attitudes and cultural issues across the U.S. military. Structural issues included concerns about the existing capacity of the system, for example, the number of providers available to address the populations needs and the constraints on clinic hours and scheduling practices. The institutional attitude and cultural issues fell into two main areas: attitudes and perceptions by the leadership and the concern that those attitudes could have negative career repercussions for those who access care. CONCLUSIONS Although there have been significant efforts to improve access to mental health care, stakeholders within the military health system still perceive significant barriers to care. Efforts to ensure adequate and timely access to high-quality mental health care for service members will need to appropriately respond to capacity constraints and organizational and institutional culture.

Comparing Quality of Care in Veterans Affairs and Non-Veterans Affairs Settings

BackgroundCongress, veterans’ groups, and the press have expressed concerns that access to care and quality of care in Department of Veterans Affairs (VA) settings are inferior to access and quality in non-VA settings.ObjectiveTo assess quality of outpatient and inpatient care in VA at the national level and facility level and to compare performance between VA and non-VA settings using recent performance measure data.Main MeasuresWe assessed Patient Safety Indicators (PSIs), 30-day risk-standardized mortality and readmission measures, and ORYX measures for inpatient safety and effectiveness; Healthcare Effectiveness Data and Information Set (HEDIS®) measures for outpatient effectiveness; and Consumer Assessment of Healthcare Providers and Systems Hospital Survey (HCAHPS) and Survey of Healthcare Experiences of Patients (SHEP) survey measures for inpatient patient-centeredness. For inpatient care, we used propensity score matching to identify a subset of non-VA hospitals that were comparable to VA hospitals.Key ResultsVA hospitals performed on average the same as or significantly better than non-VA hospitals on all six measures of inpatient safety, all three inpatient mortality measures, and 12 inpatient effectiveness measures, but significantly worse than non-VA hospitals on three readmission measures and two effectiveness measures. The performance of VA facilities was significantly better than commercial HMOs and Medicaid HMOs for all 16 outpatient effectiveness measures and for Medicare HMOs, it was significantly better for 14 measures and did not differ for two measures. High variation across VA facilities in the performance of some quality measures was observed, although variation was even greater among non-VA facilities.ConclusionsThe VA system performed similarly or better than the non-VA system on most of the nationally recognized measures of inpatient and outpatient care quality, but high variation across VA facilities indicates a need for targeted quality improvement.

Quality of care measures for the management of unhealthy alcohol use

There is a paucity of quality measures to assess the care for the range of unhealthy alcohol use, ranging from risky drinking to alcohol use disorders. Using a two-phase expert panel review process, we sought to develop an expanded set of quality of care measures for unhealthy alcohol use, focusing on outpatient care delivered in both primary care and specialty care settings. This process generated 25 candidate measures. Eight measures address screening and assessment, 11 address aspects of treatment, and six address follow-up. These quality measures represent high priority targets for future development, including creating detailed technical specifications and pilot testing them to evaluate their utility in terms of feasibility, reliability, and validity.

“You Should Drink Less”: Frequency and Predictors of Discussions Between Providers and Patients About Reducing Alcohol Use

ABSTRACT Background: Brief intervention is recommended for individuals who misuse alcohol, but studies vary on how frequently patients talk with their providers about alcohol use. Objectives: We examined whether veterans who had recently screened positive for alcohol misuse reported having conversations about their alcohol use with their providers. Methods: Following a positive screening for alcohol misuse during a primary care visit in 2013, veterans completed a telephone interview on alcohol use, conversations with their providers about drinking, and factors potentially associated with such conversations. The final analysis sample included 881 veterans; we conducted descriptive statistics and multivariable regression analyses. Results: Most veterans (83%) reported that their provider asked about drinking. Among these, 65% reported being advised to drink less, and 36% reported being advised to abstain. Veterans who received their healthcare from Veterans Health Administration (VA) had over twice the odds of reporting advice to reduce/abstain from drinking (adjusted odds ratio (AOR) = 2.34, 95% confidence interval (CI) = 1.46, 3.75). Veterans who reported heavy episodic drinking were more likely to report advice to reduce/abstain from drinking than those who did not report (AOR = 1.83, 95% CI = 1.30, 2.57) and veterans who reported heavy drinking were more likely to report such advice (AOR = 2.40, 95% CI = 1.69, 3.40). Conclusions/Importance: Most veterans with alcohol misuse reported receiving advice to reduce or abstain from drinking. Veterans with excessive alcohol use and those receiving all or most of their care from VA were more likely to report receiving such advice. Self-report of receiving advice may be an important approach to assessing appropriate follow-up after detection of alcohol misuse.

Military Mental Health Care: Provider Perspectives on Treating PTSD and Depression

The Military Health System (MHS) plays a critical role in maintaining a physically and psychologically healthy force. Ensuring the quality and availability of programs and services targeting two of the most common mental health conditions diagnosed and treated in the MHS—posttraumatic stress disorder (PTSD) and depression—is a key contributor to this goal. This research brief provides data on various aspects of the MHS capacity to treat PTSD and depression.
