Study: Looking for the uninsured in Massachusetts? Check opioid dependent persons seeking detoxification

An interesting study from Drug and Alcohol Dependence cites the rate of uninsurance at a large Massachusetts detox program as 23% in the 2013 sample they observed (five years after the insurance mandate). That's nearly five times higher than the state average of 4.8%. The authors highlight correlates of being uninsured (table below), which include being young and being male (expected), but also having a higher level of education (unexpected). Finally, more than half of the uninsured participants in the study had been so for more than one year, highlighting the ongoing need for outreach and education about public programs.

Here is the abstract via ScienceDirect:

Abstract

Background

We examined the rate of uninsurance among persons seeking detoxification at a large drug treatment program in Massachusetts in 2013, five years after insurance mandates.

Methods

We interviewed three hundred and forty opioid dependent persons admitted for inpatient detoxification in Fall River, Massachusetts. Potential predictors of self-reported insurance status included age, gender, ethnicity, employment, homelessness, years of education, current legal status, and self-perceived health status.

Results

Participants mean age was 32 years, 71% were male, and 87% were non-Hispanic Caucasian. Twenty-three percent were uninsured. In the multivariate model, the odds of being uninsured was positively associated with years of education (OR = 1.22, 95%CI 1.03; 1.46, p < .05), higher among males than females (OR = 2.63, 95%CI 1.33; 5.20, p < .01), and inversely associated with age (OR = 0.94, 95%CI 0.90; 0.98, p < .01).

Conclusion

Opioid dependent persons recruited from a detoxification program in Massachusetts are uninsured at rates far above the state average. With the arrival of the Affordable Care Act, drug treatment programs in Massachusetts and nationally will be important sites to target to expand health coverage.
And here's a table from the report:

Are Financial Incentives the Answer to SBIRT Implementation?

Researchers from Imperial College London may have found a way to increase alcohol screening and brief intervention in a primary care setting: financial incentives. The results, published online Dec. 26 in the Journal of Public Health, show that offering a points-based incentive for successful screening, brief intervention and referral to specialists significantly increased the number of patients who were screened. As a result, the authors say, more patients with risky alcohol intake were identified and offered care, reducing hazardous and harmful drinking in some.

While the evidence for SBIRT is abundant and well-known, there have been considerable problems in promoting widespread implementation - especially in primary care. Financial incentives could be one effective means of changing this. (Granted, a large-scale effort by the federal government or the insurance companies would likely be required to provide funding. In this study, data was collected from 2008-2011, until the UK's Quality and Outcomes Framework funding was withdrawn.)

Abstract

Introduction Alcohol screening and brief intervention (ASBI) is effective but underprovided in primary care. Financial incentives may help address this. This study assesses the impact of a local pay-for-performance programme on delivery of ASBI in UK primary care.
Methods Longitudinal study using data from 30 general practices in north-west London from 2008 to 2011 with logistic regression to examine disparities in ASBI delivery.
Results Of 211 834 registered patients, 45 040 were targeted by the incentive (cardiovascular conditions or high risk; mental health conditions), of whom 65.7% were screened (up from a baseline of 4.8%, P< 0.001), compared with 14.7% of non-targeted patients (P < 0.001). Screening rates were lower after adjustment in younger patients, White patients, less deprived areas and in patients with mental health conditions (P < 0.05). Of those screened, 11.5% were positive and 88.6% received BI. Men and White patients were significantly more likely to screen positive. Women and younger patients were less likely to receive BI. 30.1% of patients re-screened were now negative. However, patients with mental health conditions were less likely to re-screen negative than those with cardiovascular conditions.
Conclusion Financial incentives appear to be effective in increasing delivery of ASBI in primary care and may reduce hazardous and harmful drinking in some patients. The findings support universal rather than targeted screening.

Cochrane Releases New Reviews on MAT

The highly-respected Cochrane Library, known for its meticulous reviews of the current state of medical knowledge, has updated and released two reviews on medication-assisted treatment recently. The first, "Maintenance agonist treatments for opiate-dependent women", aims to " assess the effectiveness of any maintenance treatment alone or in combination with psychosocial intervention compared to no intervention, other pharmacological intervention or psychosocial interventions for child health status, neonatal mortality, retaining pregnant women in treatment and reducing the use of substances." The second, "Pharmacological interventions for drug-using offenders" aims to " assess the effectiveness of pharmacological interventions for drug-using offenders in reducing criminal activity and/or drug use." In both cases, the authors note the effectiveness of opioid medications in assisting patients to achieve desired outcomes (although the effect on criminal activity in the second study was significant, but less pronounced). However, they cautioned against generalizing the findings as the body of evidence of both topics is still too small.

Here are the abstracts, via Wiley:

Maintenance agonist treatments for opiate-dependent pregnant women

Abstract

Background

The prevalence of opiate use among pregnant women can range from 1% to 2% to as high as 21%. Heroin crosses the placenta and pregnant, opiate-dependent women experience a six-fold increase in maternal obstetric complications such as low birth weight, toxaemia, third trimester bleeding, malpresentation, puerperal morbidity, fetal distress and meconium aspiration. Neonatal complications include narcotic withdrawal, postnatal growth deficiency, microcephaly, neuro-behavioural problems, increased neonatal mortality and a 74-fold increase in sudden infant death syndrome.

Objectives

To assess the effectiveness of any maintenance treatment alone or in combination with psychosocial intervention compared to no intervention, other pharmacological intervention or psychosocial interventions for child health status, neonatal mortality, retaining pregnant women in treatment and reducing the use of substances.

Search methods

We searched the Cochrane Drugs and Alcohol Group Trials Register (September 2013), PubMed (1966 to September 2013), CINAHL (1982 to September 2013), reference lists of relevant papers, sources of ongoing trials, conference proceedings and national focal points for drug research. We contacted authors of included studies and experts in the field.

Selection criteria

Randomised controlled trials assessing the efficacy of any maintenance pharmacological treatment for opiate-dependent pregnant women.

Data collection and analysis

We used the standard methodological procedures expected by The Cochrane Collaboration.

Main results

We found four trials with 271 pregnant women. Three compared methadone with buprenorphine and one methadone with oral slow-release morphine. Three out of four studies had adequate allocation concealment and were double-blind. The major flaw in the included studies was attrition bias: three out of four had a high drop-out rate (30% to 40%) and this was unbalanced between groups.
Methadone versus buprenorphine: the drop-out rate from treatment was lower in the methadone group (risk ratio (RR) 0.64, 95% confidence interval (CI) 0.41 to 1.01, three studies, 223 participants). There was no statistically significant difference in the use of primary substance between methadone and buprenorphine (RR 1.81, 95% CI 0.70 to 4.69, two studies, 151 participants). For both, we judged the quality of evidence as low. Birth weight was higher in the buprenorphine group in the two trials that could be pooled (mean difference (MD) -365.45 g (95% CI -673.84 to -57.07), two studies, 150 participants). The third study reported that there was no statistically significant difference. For APGAR score neither of the studies which compared methadone with buprenorphine found a significant difference. For both, we judged the quality of evidence as low. Many measures were used in the studies to assess neonatal abstinence syndrome. The number of newborns treated for neonatal abstinence syndrome, which is the most critical outcome, did not differ significantly between groups. We judged the quality of evidence as very low.
Methadone versus slow-release morphine: there was no drop-out in either treatment group. Oral slow-release morphine seemed superior to methadone for abstinence from heroin use during pregnancy (RR 2.40, 95% CI 1.00 to 5.77, one study, 48 participants). We judged the quality of evidence as moderate.
Only one study which compared methadone with buprenorphine reported side effects. For the mother there was no statistically significant difference; for the newborns in the buprenorphine group there were significantly fewer serious side effects.
In the comparison between methadone and slow-release morphine no side effects were reported for the mother, whereas one child in the methadone group had central apnoea and one child in the morphine group had obstructive apnoea.

Authors' conclusions

We did not find sufficient significant differences between methadone and buprenorphine or slow-release morphine to allow us to conclude that one treatment is superior to another for all relevant outcomes. While methadone seems superior in terms of retaining patients in treatment, buprenorphine seems to lead to less severe neonatal abstinence syndrome. Additionally, even though a multi-centre, international trial with 175 pregnant women has recently been completed and its results published and included in this review, the body of evidence is still too small to draw firm conclusions about the equivalence of the treatments compared. There is still a need for randomised controlled trials of adequate sample size comparing different maintenance treatments.

Pharmacological interventions for drug-using offenders

Abstract

Background

The review represents one in a family of four reviews focusing on a range of different interventions for drug-using offenders. This specific review considers pharmacological interventions aimed at reducing drug use and/or criminal activity for illicit drug-using offenders.

Objectives

To assess the effectiveness of pharmacological interventions for drug-using offenders in reducing criminal activity and/or drug use.

Search methods

Fourteen electronic bibliographic databases (searched between 2004 and 21 March 2013) and five additional Web resources (searched between 2004 and 11 November 2011) were searched. Experts in the field were contacted for further information.

Selection criteria

Randomised controlled trials assessing the efficacy of any pharmacological interventions for reducing, eliminating or preventing relapse in drug-using offenders were included. Data on the cost and cost-effectiveness of interventions were reported.

Data collection and analysis

We used standard methodological procedures as expected by The Cochrane Collaboration.

Main results

A total of 76 trials across the four reviews were identified. After a process of prescreening had been completed, 17 trials were judged to meet the inclusion criteria for this specific review (six of the 17 trials are awaiting classification for the review). The remaining 11 trials contained a total of 2,678 participants. Nine of the eleven studies used samples with a majority of men. The interventions (buprenorphine, methadone and naltrexone) were compared to non pharmacological treatments (e.g., counselling) and other pharmacological drugs. The methodological trial quality was poorly described, and most studies were rated as 'unclear' by the reviewers. The biggest threats to risk of bias were generated through blinding (performance and detection bias) and incomplete outcome data (attrition bias). When combined, the results suggest that pharmacological interventions do significantly reduce subsequent drug use using biological measures, (three studies, 300 participants, RR 0.71 (95% CI 0.52 to 0.97)), self report dichotomous data (three studies, 317 participants, RR 0.42, (95% CI 0.22 to 0.81)) and continuous measures (one study, MD -59.66 (95% CI -120.60 to 1.28)) . In the subgroups analysis for community setting, (two studies, 99 participants: RR 0.62 (95% CI 0.35 to 1.09)) and for secure establishment setting, (one study, 201 participants: RR 0.76 (95% CI 0.52 to 1.10)), the results are no longer statistically significant. Criminal activity was significantly reduced favouring the dichotomous measures of re arrest, (one study, 62 participants, RR 0.60 (95% CI 0.32 to 1.14)), re-incarceration, (three studies, 142 participants, RR 0.33 (95% CI 0.19 to 0.56)) and continuous measures (one study, 51 participants, MD -74.21 (95% CI -133.53 to -14.89)). Findings on the effects of individual pharmacological interventions on drug use and criminal activity show mixed results. Buprenorphine in comparison to a non pharmacological treatment seemed to favour buprenorphine but not significantly with self report drug use, (one study, 36 participants, RR 0.58 (95% CI 0.25 to 1.35)). Methadone and cognitive behavioural skills in comparison to standard psychiatric services, did show a significant reduction for self report dichotomous drug use (one study, 253 participants, RR 0.43 (95% CI 0.33 to 0.56)) but not for self report continuous data (one study 51 participants) MD -0.52 (95% CI -1.09 to 0.05)), or re incarceration RR 1.23 (95% CI 0.53 to 2.87)). Naltrexone was favoured significantly over routine parole and probation for re incarceration (two studies 114 participants, RR 0.36 (95% CI 0.19 to 0.69)) but no data was available on drug use. Finally, we compared each pharmacological treatment to another. In each case we compared methadone to: buprenorphine, diamorphine and naltrexone. No significant differences were displayed for either treatment for self report dichotomous drug use (one study, 193 participants RR 1.23 (95% CI 0.86 to 1.76)), continuous measures of drug use MD 0.70 (95% CI -5.33 to 6.73) or criminal activity RR 1.25 (95% CI 0.83 to 1.88)) between methadone and buprenorphine. Similiar results were found for comparisons with Diamorphine with no significant differences between the drugs for self report dichotomous drug use for arrest (one study, 825 participants RR 1.25 (95% CI 1.03-1.51)) or Naltrexone for dichotomous measures of re incarceration (one study, 44 participants, RR 1.10 (95% CI 0.37 to 3.26)), and continuous outcome measure of crime MD -0.50 (95% CI -8.04 to 7.04)) or self report drug use MD 4.60 (95% CI -3.54 to 12.74)).

Authors' conclusions

Pharmacological interventions for drug-using offenders do appear to reduce overall subsequent drug use and criminal activity (but to a lesser extent). No statistically significant differences were displayed by treatment setting. Individual differences are displayed between the three pharmacological interventions (buprenorphine, methadone and naltrexone) when compared to a non pharmacological intervention, but not when compared to each other. Caution should be taken when interpreting these findings, as the conclusions are based on a small number of trials, and generalisation of these study findings should be limited mainly to male adult offenders. Additionally, many studies were rated at high risk of bias because trial information was inadequately described.

Is Florida Turning a Corner?

According to a brand new study, published online this week in the journal, Pharmacoepidemiology and Drug Safety, Florida's recent legislative actions to 1.) strengthen the state's prescription drug monitoring program, and 2.) toughen the regulation of the state's pain clinics, seem to be having the desired effect: drug diversion has been dropping steadily since 2011. In addition, according to the state's commission of medical examiners, prescription opioid overdose deaths are dropping too. Here's the abstract from the article and a figure of the models of longitudinal change, according to each drug: 

Reductions in prescription opioid diversion following recent legislative interventions in Florida
Surratt, et al., 2013

Purpose
Florida has been at the center of the nation's ongoing prescription opioid epidemic, with largely unregulated pain clinics and lax prescribing oversight cited as significant contributors to the opioid problem in the state.

Methods
In an effort to mitigate prescription opioid abuse and diversion in Florida, legislative interventions were implemented during 2010 and 2011, which included two primary elements: (i) comprehensive legislation to better regulate the operation of pain clinics; and (ii) a statewide prescription drug monitoring program to promote safer prescribing practices. Using systematic longitudinal data collected on a quarterly basis from law enforcement agencies across Florida, this report examined changes in prescription opioid diversion rates following implementation of these regulatory initiatives. Quarterly diversion rates for buprenorphine, fentanyl, hydrocodone, hydromorphone, methadone, morphine, oxycodone, and tramadol were calculated, and subsequently, hierarchical linear models were fit to test for differences in diversion rates over the 15 quarter period of interest.

Results
Significant declines in diversion rates were observed for oxycodone, methadone, and morphine; hydrocodone displayed a marginally significant decline.

Conclusions
This study documented reductions in statewide opioid diversion rates following implementation of Florida's pain clinic and prescription drug monitoring program legislative interventions. Although these initial findings appear promising, continued surveillance of diversion is clearly warranted. Copyright © 2013 John Wiley & Sons, Ltd.

Poor and Non-Whites Less Likely to Receive Opioid for Pain in ERs

Race and Socioeconomic Status Affect Emergency Department Opioid Prescribing for Pain

Prior research suggests that factors besides pain—such as patient race and ethnicity—affect opioid prescribing for pain, but those studies have often not adjusted for socioeconomic status (SES). In this study, investigators examined the association between race, ethnicity, and neighborhood SES on prescription of an opioid during an emergency department (ED) visit for moderate or severe pain in the National Hospital Ambulatory Care Survey. During 4 years there were over 183 million visits and opioids were prescribed during 50,264 of them.
  • Compared with patients living in areas with the highest SES, patients living in areas with the lowest SES were less likely to receive opioids (39% versus 49% when neighborhood poverty was >20%; 41% versus 47% when median income was <$33,000; and 43% versus 46% when <13 a="" bachelor="" degree="" held="" li="" s="">
  • Black (39% versus 46% for white) and Hispanic (40% versus 45% for non-Hispanic) patients were less likely to receive opioids.
  • All differences were significant in analyses adjusted for race, ethnicity, SES, sex, pain severity, injury, hospital type, past ED visits, and geography.

Comments:

This study adjusted for neighborhood rather than individual SES. Nonetheless, it does provide support for the hypothesis that race, ethnicity, and SES impact opioid receipt for pain. Clinicians should be aware that this may happen, and researchers should attend to discovering why, with an eye toward eliminating any inappropriate disparities.Richard Saitz MD, MPH

If You Build It, They Will Drink

If there were lingering doubts about the effect of alcohol availability on alcohol consumption, a host of new studies seem to lead the reader to the same conclusion: that increases in availability are correlated to increases in consumption. In other words: if you build it (bar, liquor store, etc), we will drink. What's more, in many cases, it's not just drinking that will happen. So-called alcohol outlet density has been linked to interpersonal and intimate partner violence, adolescent consumption and beliefs about alcohol, and even alcohol-attributable deaths. On the other hand, raising the minimum prices or implementing taxes on alcohol sales seems to go a long way in reducing these potential harms.

The journal, Addiction, has published several of these studies online in the past few weeks. Gruenewald and colleagues analyzed survey data from 50 California cities with populations between 50,000 - 500,000. They found "greater on-premise outlet densities were related to greater drinking frequencies and volumes, and use of on-premise drinking places" (like bars and restaurants).  The researchers concluded that, in addition to characteristics of the individual drinkers (e.g. "impulsivity, risky driving), alcohol availability is correlated with consumption and related problems.

Also in-press at Addiction, Paschall and colleagues analyzed the same sample, but instead focused on adolescent drinking. Some 1478 California youths, aged 13-17, responded to survey questions about past-year alcohol consumption, perceived availability, and questions related to underage enforcement and parental views toward drinking. The answers to these questions were then compared against alcohol outlet (bar) density, public policy, law enforcement activity and city demographics. The authors found that adolescent behaviors and attitudes were significantly affected by their environments. For example, past-year alcohol use was positively correlated to bar density and inversely correlated to "the comprehensiveness and stringency of local alcohol policies". In addition, higher rates of adult drinking were associated with greater increases of past-year adolescent drinking over the three-year study period.

Over in Alcohol and Alcoholism, Grubesic and colleagues studied the association between outlet density in Philadelphia and violent crime. Once again, the researchers found consistent association between the two. Here is a pair of maps, the first showing assault density, the second showing outlet density:


Contrary to the popular belief, no association was found between assault density and "transportation nodes and risky retailers". However, alcohol expenditures and general commercial activity were "positively and significantly" associated with assault density. 

The connection between intimate partner violence (IPV) and alcohol outlet density seems to be well established. In 2012, Conradi and colleagues reported that the density of bars in California was positively associated with IPV-related emergency department visits between 2005-2008. Then, earlier this year, Waller and colleagues found alcohol outlet density to be positively correlated to male-to-female physical - but not sexual - IPV among a national sample. Finally, in March, Zhao and colleagues showed that alcohol outlet density was associated with an increase in alcohol-attributable deaths in British Columbia between 2002-2009. In fact, they calculated that a 10% increase in private liquor stores was associated with a 2.45%, 2.36% and 1.99% increase in acute, chronic and total alcohol-associated (AA) mortality rates.

Interestingly, the single policy that seemed to have the biggest impact in turning these numbers around: raising the minimum price for alcohol. A 10% increase in the minimum price was associated with a 31.72% reduction in "wholly AA deaths". Pretty big numbers. As Dr W observed recently, "raising taxes on alcohol would do more for public health than all the treatment in the world."

MMT and 12-Step Groups: Stigma Persists

In his latest contribution to the academic literature, William L. White and colleagues turn their focus on 12-Step participation among patients in methadone maintenance treatment (MMT). Rates of self-reported Narcotics Anonymous (NA) and Alcoholics Anonymous (AA) attendance were very high; however, participants frequently reported that their MMT status prevented them from taking part in many of the "key ingredients" of the groups that most members take for granted. When asked about the experience, nearly half of all respondents who had attended NA or AA reported that they had "received negative comments about methadone use" and nearly "a quarter (24.4%) reported having had a serious problem within NA or AA related to their status as a methadone patient."

The following table from the report details the "frequency with which respondents faced particular challenges":

Table 4: NA and AA Responses to MMT Patient Status                                NA            AA

Response to MM Patient Status:                                                                         (n=228)     (n=142)

Received negative comments about methadone use                                                43.0%     45.1%

Were pressured to reduce the dose of methadone                                                  21.9%     23.2%

Were pressured to stop taking methadone                                                             32.9%     34.5%

Were denied the right to speak at a meeting because of being

Were denied the right to become a sponsor because of being                                  8.8%        9.9%
in methadone treatment


White and colleagues implemented this small study at not-for-profit opioid treatment program (OTP) in the Northeastern US. A total of 322 respondents answered a 53-question survey about their participation in recovery support groups. Of the 322, 259 (80.4%) reported a primary affiliation with a recovery support group. Of these, 88.8% reported it to be in some way a 12-Step group. Importantly, 66% of respondents reported past-year NA/AA participation, with 88-89% reporting the group was "helpful".

Despite these figures, the authors found MMT patients had low rates of participation in the "key ingredients" that seem to be critical influencers of long-term recovery outcomes: having a home group (50%), having a sponsor (26%), sponsoring others (13%), attending 12-Step social events (23%), and active step work (21%).

Anecdotally, we see a lot of patients at Alltyr who have a hard time finding a place in the local 12-Step scene. We even began compiling a list of medication-friendly meetings in the Twin Cities as we learned about them, but the stigma associated with maintenance is still prevalent. Could it be that we are on the verge of another breakthrough in medication acceptance? After all, there was a time when you weren't considered "sober" if you were on antidepressant or antipsychotic medications (but now, as Dr W likes to say, you're more likely to be referred to the psychiatrist by your sponsor than by anyone else). We would be interested to hear reader stories about this experience - or opinions on the topic. Are things changing - or not?
