Summary

What is already known about this topic?

Overdose deaths involving opioid pain medications have reached epidemic levels in the United States, in part because of high opioid prescribing rates. Health systems and insurers play an important role in the delivery and management of pain care.

What is added by this report?

A private insurer implemented a comprehensive opioid utilization policy that included treatment plans, risk assessments, patient-provider agreements, requirements for dispensing from a single pharmacy, prior authorizations, quantity limits, and a ban on mail-order opioid prescriptions. Following implementation, monthly opioid prescribing rates and percentage of members with opioid prescriptions declined significantly.

What are the implications for public health practice?

Public health agencies and private health insurers can collaborate to ensure that both public and private insurers promote best practices in opioid prescribing.

Overdose deaths involving opioid pain medications are epidemic in the United States, in part because of high opioid prescribing rates and associated abuse of these drugs (1). In 2014, nearly 2 million U.S. residents either abused or were dependent on prescription opioids (2). In Massachusetts, unintentional opioid-related overdose deaths, including deaths involving heroin, increased 45% from 2012 to 2013.* In 2014, the rate of these deaths reached 20.0 per 100,000, nearly 2.5 times higher than the U.S. rate overall (3,4). On July 1, 2012, Blue Cross Blue Shield of Massachusetts (BCBSMA), the largest insurer in the state with approximately 2.8 million members,† implemented a comprehensive opioid utilization program after learning that many of its members were receiving new prescriptions with a >30-day supply of opioids. The 2016 CDC Guideline for Prescribing Opioids for Chronic Pain recommends avoiding opioids as a first-line therapy for chronic pain and limiting quantities when initiating opioids for acute pain (5). CDC analyzed BCBSMA prescription claims data for the period 2011–2015 to assess the effect of the new utilization program on opioid prescribing rates. During the first 3 years after policy implementation, the average monthly prescribing rate for opioids decreased almost 15%, from 34 per 1,000 members to 29. The percentage of BCBSMA members per month with current opioid prescriptions also declined. The temporal association between implementation of the program and statistically significant declines in both prescribing rates and proportion of members using opioids suggests that the BCBSMA initiative played a role in reducing the use of prescription opioids among its members. Public and private insurers in the United States could benefit from developing their own best practices for prescription opioid utilization that ensure accessible pain care, while reducing the risk for dependence and abuse associated with these drugs.

In 2012, BCBSMA analyzed its 2011 pharmacy claims data to determine the number of members receiving large quantities of opioid prescriptions from multiple providers. In 2011, approximately 30,000 members received new prescriptions of short-acting opioids with a >30-day supply; 25% of these members obtained opioid prescriptions from multiple providers. BCBSMA’s opioid utilization program was developed collaboratively among an extensive network of stakeholders, including physicians, nurses, pharmacists, actuaries, lawyers, data analysts, medical societies, medical and pharmacy boards, the Massachusetts Pain Initiative, and the top 10 opioid-dispensing pharmacies in Massachusetts (Box).

The BCBSMA prescription opioid utilization program was designed around expert-defined best practices for opioid prescribing that include formal agreements between patient and provider, a requirement for BCBSMA approval prior to dispensing new opioid prescriptions, and quantity limits.§ The program requires providers to conduct a risk assessment for abuse that the patient must sign. Physicians and patients work together to develop a treatment plan that considers options other than prescription opioids. When the decision to prescribe opioids is made, a formal agreement between patient and prescriber outlines specific behaviors expected of both parties. In addition, the prescriber must provide a diagnosis and rationale for prescribing an opiate as part of the prior authorization process. BCBSMA coverage requires prior authorization (including review by a BCBSMA clinician who then notifies the pharmacy) before dispensing new short-acting opioid prescriptions with a >30-day supply and for all new long-acting opioid prescriptions. Pharmacy mail orders are not permitted. If opioid misuse is suspected or if coordination of care among multiple providers is indicated, patients might be assigned a single pharmacy to dispense all opioid prescriptions. Identified patients with chronic pain are referred to case managers who advise on nonopioid therapies. Oncology patients and terminally ill persons are exempt from the requirements for prior authorization for new prescriptions. Members continue to have coverage for physical therapy, pain management, addiction treatment, chiropractic services, and cognitive behavioral therapy.

A retrospective analysis was conducted using BCBSMA prescription claims data from the period July 2011–June 2015. The pre-implementation period was defined as July 1, 2011–June 30, 2012, and the postimplementation period was defined as July 1, 2012–June 30, 2015. All data were deidentified before analysis. Average monthly prescribing rates per 1,000 members and percentage of members with opioid prescriptions were calculated for short-acting, long-acting,** and for both opioid types combined. Average monthly counts of opioid prescriptions for oncology members were also tabulated. To assess the effects of the opioid utilization program, preprogram and postprogram rates were modeled using an interrupted time series analysis. Outcomes were the proportions of members with prescriptions per month and number of prescriptions per total members per month; changes in rates were estimated by two regression coefficients, one for each period. Differences were considered statistically significant if the 95% confidence interval for the coefficient corresponding to the difference in slopes excluded zero. Prescriptions for buprenorphine, indicated for the treatment of opioid use disorder, were examined separately to determine how prior authorization requirements impact dispensing of drugs used in medication-assisted treatment. Changes in prescribing are reported for all commercial members eligible for BCBSMA pharmacy benefits (excluding patients receiving Medicare benefits).

An average of 1.5 million commercial members with pharmacy benefits were enrolled in BCBSMA each month during the study period. The average monthly prescribing rate for all opioids decreased 14.7%, from 34 per 1,000 before implementation of the program to 29 after implementation (Table 1). Although the average monthly prescribing rates for long-acting opioids remained constant at three per 1,000 members before and after program implementation periods, the average monthly prescribing rate for short-acting opioids decreased 16.1%, from 31 to 26 per 1,000 members (Figure 1). Similarly, while the percentage of all members with a long-acting opioid prescription decreased 8.3%, from 0.24% per month to 0.22%, the percentage of members with short-acting opioid prescriptions decreased 12.9%, from 2.49% per month to 2.17% after program implementation (Figure 2). The number of members with cancer diagnoses was not available to calculate opioid prescribing rates; however, the average monthly number of opioid prescriptions dispensed to members with cancer diagnoses declined 9% following program implementation, which was less than among all members.

Results of the interrupted time series analysis showed a 6%–9% annual decline in the percentage of members on short-acting and long-acting opioid prescriptions and in opioid prescribing rates after implementation of the opioid utilization program compared with the pre-implementation period (Table 2). All differences were statistically significant, regardless of medication type. Overall, the estimated quantity of opioids dispensed before and after implementation of the program indicate that approximately 21 million fewer opioid doses were dispensed in the first 3 years after implementation. Data on prior authorization requirements for buprenorphine indicated for the treatment of opioid use disorder, show that 17% of members with these prescriptions never sought subsequent authorization to fill them following a pharmacy declining to fill a prescription.

Discussion

After implementation of an opioid utilization program in July 2012, the number of opioid prescriptions and the percentage of members with an opioid prescription significantly decreased among BCBSMA members. However, it is possible that other events, such as changes in policies and media coverage, contributed to the decline. Although the declines in average monthly prescribing rate and the percentage of BCBSMA members with opioid prescriptions appear modest, these data represent significant changes for a 2.8 million-member health plan. In the postimplementation period, the average monthly number of prescriptions for short-acting and long-acting opioids decreased by 14,000. The prior authorization requirement for new short-acting opioid prescriptions for >30 days prompts providers to evaluate the medical necessity of initiating opioids for extended periods, along with the concomitant risks. The decreases in dispensed opioids were highest for short-acting opioids, which also account for most of the opioid prescriptions. In accordance with a Massachusetts statute, the prior authorization requirement was changed to >21 days in August 2016.††

For nearly one in five patients, the pharmacy did not fill a buprenorphine prescription because it did not meet criteria and the patient did not subsequently seek authorization. The rejection might have occurred because the provider wrote the prescription for an off-label use or because the daily dosage was not within recommended parameters. Additional analyses by BCBSMA found that nearly one third of patients were receiving these prescriptions from multiple providers, indicating a potential problem with poorly coordinated care. Whereas prior authorization might prevent misuse or diversion of buprenorphine, it might also be a barrier to medication-assisted treatment. Insurers can weigh the benefits and harms of requiring prior authorization for drugs used as part of medication-assisted treatment to determine what is most effective for their member population.

Although oncology patients were exempt from prior authorization requirements for new prescription opioids, the number of opioid prescriptions also declined among these patients following program implementation. Insurers frequently observe a sentinel effect following a new drug utilization program in which provider behaviors extend to their entire patient populations (6). Effective management of pain is a core component of quality end-of-life care and care for patients with serious advanced illness. To avoid unintentionally limiting access to pain medication for these patients, insurers can evaluate how policies affect this population to ensure that comprehensive care addresses their specific needs, including pain management. Data are not available on the impact of the decrease in prescribing among BCBSMA oncology patients on their pain management and functioning. However, in the 4 years since program launch, the only appeal of a claim related to the insurer’s policy resulted from a clerical error, suggesting that these members continue to receive medically appropriate access to pain medication.

The findings in this report are subject to at least four limitations. First, rates for nononcology opioid prescriptions might be underestimated by the inclusion of oncology members in the denominator, but the impact on trends is likely minimal because of the relatively small number of members who are oncology patients. Second, the role of other factors that potentially affected prescribing rates during this period (e.g., media coverage of opioids, increased use of the prescription monitoring program, and overlapping policy changes) could not be evaluated. In 2012, for example, the Massachusetts state legislature provided a statutory directive to address prescription drug abuse (7). Effective October 2014, the Drug Enforcement Administration rescheduled hydrocodone combination products to schedule II,§§ which was followed by a decrease in hydrocodone prescribing at the national level (8). Although tramadol is a frequently prescribed opioid, it was excluded from the program. As a Schedule IV opioid, tramadol has a lower potential for abuse than Schedule II and Schedule III opioids; it is possible that providers, cognizant of the risks associated with opioids, altered their prescribing behaviors and substituted tramadol where possible. However, tramadol prescribing data from BCBSMA show neither an increasing nor decreasing trend, indicating tramadol substitution was not likely. Third, these results reflect a privately insured population and might not be generalizable to other populations, including persons covered under public health plans. Finally, it is not known from these data how patient pain and function were affected by limiting access to opioid prescriptions.

State and federal initiatives to address the opioid epidemic in the United States have been implemented in the past several years, with some resulting in reduced opioid prescribing (8,9). The U.S. Department of Health and Human Services initiative targets three priority areas: improving opioid prescribing practices, distribution of naloxone to reverse overdoses, and access to medication-assisted treatment (10). The significant decrease in dispensing of opioids immediately after the implementation of the BCBSMA opioid utilization program suggests that this intervention played a role in the reduction of the observed monthly prescription rate. As part of quality improvement efforts, public and private insurers can implement policies that promote best practices in opioid prescribing to reduce risk among their members while ensuring access to appropriate pain management. The CDC Guideline for Prescribing Opioids for Chronic Pain (5), released March 2016, supports this effort and provides a comprehensive list of recommendations that can inform insurer opioid utilization programs and policies.
