Charlson Comorbidity Index is a validated method of estimating the 10-year risk of death from concurrent disease. The higher the score, the higher the predicted risk of mortality. The index score is based on 17 different medical conditions categories defined by the International Classification of Disease. Each comorbidity category has an associated weight (from 1 to 6). The condition-specific scores are summed for the overall score (range 0 to 29). Refer to online calculators to predict mortality risk for a given score.

Morphine Equivalent Daily Dose (MEDD) is calculated by determining the total daily amount of a prescribed opioid, multiplying the dose of the opioid by a conversion factor to ascertain morphine milligram equivalents and then adding up the dosage.

Only patients who survived throughout the study time period and with data documented in the electronic medical record system 12-months before the index date are included in the analysis.

Participants' opioid medication orders were monitored for 12 months prior to and following entry into study (index event). This outcome represents the rate ratio of average MEDD in the post-index versus pre-index periods for the Behavioral Collaborative Care (BHI-CCM + EMR-CDS) and Usual Care (EMR-CDS only) groups. The rate ratio compares the average dose of opioid prescription in the post-index period to the pre-index period. A rate ratio less than 1 indicates that the average dose decreased.

All participants who survived through end of study and had at least one documented opioid medication order, excluding buprenorphine and methadone, in the 12-month pre-index period are included in the analysis. Patients who died during the course of the study or were missing prescription data at baseline are not included in this analysis.
