Executive Summary

Background

The opioid addiction epidemic is one of America’s foremost health crises. According to the most recent statistics from the Centers for Disease Control and Prevention (CDC), opioids (including prescription opioids and heroin) kill more than 33,000 people annually, which is more than any year on record and more than at the peak of the human immunodeficiency virus (HIV) epidemic.1 Opioid abuse/overdose is considered a leading cause of shortened life expectancy in the U.S.2

The nation’s opioid epidemic reflects a complex set of circumstances. The pattern of opioid prescribing—including dose and duration-—and the patient’s risk factors of age, gender and condition are major determinants of whether a patient becomes dependent.3 As cases of opioid use disorder skyrocket among the commercially insured, this data shed new light on the specific prescribing practices and use that pose a significant threat to patient health.

The Analysis

Twenty-one percent of Blue Cross and Blue Shield (BCBS) commercially-insured members filled at least one opioid prescription in 2015. Data also show BCBS members with an opioid use disorder diagnosis spiked 493 percent over a seven year period. The report analyzes medical claims from BCBS commercially-insured members diagnosed with opioid abuse disorder from 2010 through 2016.4 Specifically, it looks at the degree of prescription opioid use—in terms of the dose and duration of opioid prescriptions—and how this relates to opioid dependence.
 

Study found 21% of BCBS commercially insured members filled at least one prescription in 2015Summary of Key Findings

  • Patients who fill high-dosage opioid prescriptions have much higher rates of opioid use disorder than patients who fill low-dose prescriptions across both short and long duration regimens.
  • Women age 45 and older have higher rates of opioid use disorder than men. Males younger than 45 have higher rates of opioid use disorder than females. Females fill more opioid prescriptions than males across all age groups.
  • Long-duration prescription opioid use and opioid use disorder align geographically, with the highest rates in the South and the Appalachian Region.
  • The 65 percent rate of increase in the use of medicationassisted treatments does not match the 493 percent rate of increase in opioid use disorder diagnoses from 2010 through 2016. States that have experienced the greatest growth in the use of medication-assisted treatments are not necessarily the areas most impacted by opioid use disorders. Higher rates of treatment relative to opioid use disorder occur in New England and lower rates occur in the South and parts of the Midwest.
  • While opioids are more likely to be prescribed for select acute short term conditions, prescriptions for chronic conditions are twice as likely to extend past 45 days and three times as likely to reach a “high dose” level which, as noted above, leads to higher levels of opioid use disorder.

Opioid Prescription Regimens by Dose and Duration

In this report, prescription regimens were categorized on the basis of duration (number of days) and dosage (strength), consistent with CDC convention. For duration, regimens greater than 90 days are considered long duration and those less than 90 days short duration. High dosage is defined in terms of the morphine-equivalent daily dose being more than 100 while low dosage is defined as a morphine-equivalent daily dose of less than 100.

For the 6.3 million unique patients in 2015 in this data set, prescription regimens break out as shown in Exhibit 1.

Opioid Use Disorder and Type of Prescription Regimen

The diagnosis of opioid use disorder increased 493 percent from 2010 to 2016, with a marked increase in diagnoses starting in 2014 (see Exhibit 2). This rise was driven potentially by increased awareness of the disorder. Nearly one percent of commercially-insured BCBS members were diagnosed with opioid use disorder in 2016.

Exhibit 2: Rate of opioid use disorder per 1,000 members

 

Patients with high-dosage opioid prescriptions have much higher rates of opioid use disorder than patients with low-dose prescriptions—even if they are for short durations (see Exhibit 3). An opioid use disorder diagnosis is more than 40 times as likely in patients who fill high-dose, short-duration regimens than it is for those who fill low-dose, short-duration regimens. An opioid use disorder diagnosis is seven times more likely in patients who fill high-dose, long-duration regimens than it is for those who fill low-dose, long-duration regimens.

A closer look at prescription dosage and duration reveals patterns in the relationship between rates of opioid use disorder (see Exhibit 4). A preliminary analysis of opioid prescription regimens show that regimens of longer durations and higher dosages are associated with higher rates of opioid use disorder.

Policy debates on preventing opioid use disorder have focused recently on patterns of short-term opioid use. The breakout durations less than 90 days (55 percent of total users) is shown in Exhibit 5. Approximately 45 percent of this group had prescriptions of seven or fewer days with the most common duration being four and seven days.

* Rates denote opioid use disorder per 1,000 members within each dose/duration category. The same individual with different prescription regimens can be assigned to multiple categories. Future analysis will look at opioid use disorder rates for members using only their highest does/duration prescription.

Opioid Use and Gender

Women have higher rates of prescription opioid use than men (see Exhibit 6).

Exhibit 6: Percent of opioid prescriptions by gender and age in 2015

 

However, younger women have lower rates of opioid use disorder than men. This trend reverses after the age of 45 for women (see Exhibit 7), consistent with the finding that women age 45 and older also have longer prescription durations.

Regional Variation in Opioid Use Disorder

The highest rates of prescription opioid use and long-duration prescription opioid use occur in the South and lower Midwest, consistent with areas with highest rates of opioid use disorder (compare Exhibits 9 and 10).

Medication-Assisted Treatments Trends

Though critical to treating opioid use disorder, the use of medication-assisted treatments (e.g., methadone) does not always track with rates of opioid use disorder (compare Exhibits 10 and 11). For example, New England leads the nation in use of medication-assisted treatments but it has lower levels of opioid use disorder than other parts of the country.

Exhibit 11: Percent of members with opioid use disorder who received medication-assisted treatment in 2016

 

From 2010 to 2016, use of medication-assisted treatments has increased 65 percent overall, reflecting the use of buprenorphine. However, the rate of increase in the use of medication-assisted treatments does not match the rate of increase in opioid use disorder diagnoses displayed in Exhibit 2.

Pain-Related Conditions and Opioid Prescription Regimens

To better understand the relationship between pain-related health conditions and prescription opioid use, patients with select conditions5 were examined for prescription duration and dosage (see Exhibit 13). The rate of prescribing is higher for patients with acute conditions than for chronic conditions, but prescription duration is longer for patients with chronic conditions. In addition, patients with chronic conditions have a higher likelihood of receiving a high-dose prescription (which is due in part to a patient’s increased insensitivity to opioids).6 The combination of long-duration, high-dose prescription regimens increases the likelihood of opioid use disorder (see Exhibit 3).

Conclusion

The BCBS Health Index® identifies substance use disorder as the fifth most impactful condition affecting the health of commercially-insured members in the U.S. Addressing the opioid epidemic is one of America’s greatest public health challenges. Understanding the trends of prescription opioid use, which is both cause and effect of opioid addiction, helps providers, researchers and policymakers better confront this crisis. It will take a collaborative effort of health providers, insurers, communities and all levels of government working together to develop solutions that effectively meet community needs.

Methodology Notes

This is the thirteenth study of the Blue Cross Blue Shield: The Health of America Report series, a collaboration between the Blue Cross Blue Shield Association and Blue Health Intelligence, which uses a market-leading claims database to uncover key trends and insights into healthcare affordability and access to care. In addition, Axial Healthcare, an independent company, provided pharmacy consultancy services to BCBSA for this report.

The report examines the medical and pharmacy claims of more than 30 million BCBS commercially-insured members per year from 2010 to 2016 to measure the number of members with an ICD code-based diagnosis of opioid use disorder and prescriptions for medication-assisted therapy (MAT). All eligible members under age 65 were included. Pharmacy data for prescription opioid use was limited to the year 2015 and 29.2 million members to create a year point-in-time snapshot of prescription opioid use. Members with diagnoses of cancer or services for palliative care and hospice care were excluded.

Dose and duration of opioid regimens were provided by Axial Healthcare. Dose and duration regimens were calculated for each member level based on pharmacy data, which included the potency of the opioid prescribed, the dosage and the number of doses to be taken per day. The total number of unique opioid regimens and the number of unique members who were prescribed and filled an opioid in 2015 were counted by age, gender and state of residence. Rates were computed on a per 1,000-member basis or percentage basis, where noted. Members with diagnosed conditions present in 2015 were measured in aggregate to assess how many members with a certain health condition were given an opioid and the dose and duration the opioid prescribed.
