  • Ages 18 to 79 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: The source populations will be those members of the selected health plans and insurance programs identified for which full demographic, provider, facility and pharmacy data are available, and in which protected health information (PHI) can be linked to death certificate information. The four large healthcare systems that have established electronic databases for studying coded terminology outcomes selected for this study are: Kaiser Permanente Northwest; HealthCore, Inc. with access to commercial insurance data; Optum with access to commercial insurance data; and Vanderbilt University with access to Medicaid data for the State of Tennessee.

Who may be able to join

  • In the primary analysis, persons known to have had at least six months of no opioid dispensing who subsequently receive at least 70 days of Schedule II opioid dispensed within a 90-day period and who have not previously experienced an opioid overdose.
  • In a secondary analysis, persons who have been long-term users of IR/SA opioids and who switch to a different Schedule II IR/SA opioid product or to an ER/LA opioid
  • In another secondary analysis, persons with at least six months of presence in the health insurance data who have not received opioids in the preceding 30 days, and have not previously experienced an opioid overdose

Who cannot join

  • Experience of opioid overdose in the six months preceding inclusion

About this study

Official title: Incidence and Predictors of Opioid Overdose and Death Among Users of Opioid Analgesics as Measured by Diagnoses and Death Records - a Retrospective Database Study

Retrospective study to assess incidence and predictors of opioid abuse overdose and death associated with opioid overdose among patients prescribed opioid products in long-term use.

Read the detailed description

The purpose of this study is to quantify risk, and predictors of risks for opioid overdose and for death associated with opioid overdose in persons who are or have been long-term recipients of prescriptions for Schedule II opioids. The study uses coded terms in large heath databases maintained by healthcare providers and health insurers, supplemented by overdose deaths identified from the National Death Index. The terms for overdose are combined following validated rules as developed in companion studies. The study is being conducted in parallel with a prospective questionnaire-based cohort study of the same risks.

Questions about this trial

What is this clinical trial studying?

An observational study of Opioid Overdose, run by Member Companies of the Opioid PMR Consortium at 4 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 14 Jul 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Opioid overdose - fatal and nonfatal (time frame: Retrospective review over period from October 1, 2006 to December 31, 2017). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Jul 2022.
