“…17,18 The PDMP vendor uses a proprietary, largely deterministic algorithm to link prescriptions for the same individual, based on name, birth date, and address. However, an individual may not always be uniquely identified, due to nicknames, misspellings, transposed digits or characters, changes in surname, or changes in residence.…”

Association Between Initial Opioid Prescribing Patterns and Subsequent Long-Term Use Among Opioid-Naïve Patients: A Statewide Retrospective Cohort Study

et al. 2016

BACKGROUND: Long-term efficacy of opioids for noncancer pain is unproven, but risks argue for cautious prescribing. Few data suggest how long or how much opioid can be prescribed for opioid-naïve patients without inadvertently promoting long-term use. OBJECTIVE: To examine the association between initial opioid prescribing patterns and likelihood of long-term use among opioid-naïve patients. DESIGN: Retrospective cohort study; data from Oregon resident prescriptions linked to death certificates and hospital discharges. PARTICIPANTS: Patients filling opioid prescriptions between October 1, 2012, and September 30, 2013, with no opioid fills for the previous 365 days. Subgroup analyses examined patients under age 45 who did not die in the follow-up year, excluding most cancer or palliative care patients. MAIN MEASURES: Exposure: Numbers of prescription fills and cumulative morphine milligram equivalents (MMEs) dispensed during 30 days following opioid initiation (Binitiation month^). Outcome: Proportion of patients with six or more opioid fills during the subsequent year (Blong-term users^). KEY RESULTS: There were 536,767 opioid-naïve patients who filled an opioid prescription. Of these, 26,785 (5.0 %) became long-term users. Numbers of fills and cumulative MMEs during the initiation month were associated with long-term use. Among patients under age 45 using short-acting opioids who did not die in the follow-up year, the adjusted odds ratio (OR) for long-term use among those receiving two fills versus one was 2.25 (95 % CI: 2.17, 2.33). Compared to those who received < 120 total MMEs, those who received between 400 and 799 had an OR of 2.96 (95 % CI: 2.81, 3.11). Patients initiating with long-acting opioids had a higher risk of long-term use than those initiating with short-acting drugs.CONCLUSIONS: Early opioid prescribing patterns are associated with long-term use. While patient characteristics are important, clinicians have greater control over initial prescribing. Our findings may help minimize the risk of inadvertently initiating long-term opioid use.

“…Each state linked treatment data with arrest and incarceration data from their criminal justice agencies (e.g., Department of Corrections, state patrols) and stripped all personally identifying information before sending data to the study's analytic team. In Washington and Connecticut, the Link King software, which uses probabilistic matching, was used for linking the data (Campbell et al, 2008). In Oklahoma, probabilistic matching was used based on last name, fi rst name, Social Security number, date of birth, gender, and race.…”

ABSTRACT. Objective: A limited literature on racial/ethnic disparities in the treatment of substance use disorders suggests that quality of treatment may differ based on client's race/ethnicity. This study examined whether (a) disparities exist in the probability of treatment engagement, a performance measure for substance use disorders, and (b) treatment engagement is associated with similar reductions in likelihood of arrest for Whites, Blacks, Latinos, and American Indians. Method: Adult clients who began an outpatient treatment episode in 2008 in public sector specialty treatment facilities in Connecticut, New York, Oklahoma, and Washington made up the sample (N = 108,654). Administrative treatment data were linked to criminal justice data. The criminal justice outcome was defi ned as an arrest within a year after beginning treatment. Engagement is defi ned as receiving a treatment service within 14 days of beginning a new outpatient treatment episode and at least two additional services within the next 30 days. Two-step Heckman probit models and hierarchical time-to-event models were used in the analyses. Results: Black clients in New York and American Indian clients in Washington had signifi cantly lower likelihood of engagement than White clients. As moderators of engagement, race/ethnicity had inconsistent effects across states on the hazard of arrest. Conclusions: Racial/ethnic minority groups may benefi t from additional treatment support to reduce criminal justice involvement. States should examine whether disparities exist within their treatment system and incorporate disparities reduction in their quality improvement initiatives. (J. Stud. Alcohol Drugs, 76, 57-67, 2015)

“…Pleurodesis is considered as an alternative treatment when surgical repair is impossible due to an underlying comorbidity. Diverse chemical and biological substances, including autologous blood [2], talc [3,4], fibrin [5] and antibiotics [6], have demonstrated various efficiencies to treat PAL. Recently, an endobronchial valve (EBV) was successfully utilised to treat PAL [7][8][9].…”
