Drug Enforcement Agency 2014 Hydrocodone Rescheduling Rule and Opioid Dispensing after Surgery.

BACKGROUND: In 2014, the U.S. Drug Enforcement Agency reclassified hydrocodone from Schedule III to Schedule II of the Controlled Substances Act, resulting in new restrictions on refills. The authors hypothesized that hydrocodone rescheduling led to decreases in total opioid dispensing within 30 days of surgery and reduced new long-term opioid dispensing among surgical patients. METHODS: The authors studied privately insured, opioid-naïve adults undergoing 10 general or orthopedic surgeries between 2011 and 2015. The authors conducted a differences-in-differences analysis that compared overall opioid dispensing before versus after the rescheduling rule for patients treated by surgeons who frequently prescribed hydrocodone before rescheduling (i.e., patients who were functionally exposed to rescheduling's impact) while adjusting for secular trends via a comparison group of patients treated by surgeons who rarely prescribed hydrocodone (i.e., unexposed patients). The primary outcome was any filled opioid prescription between 90 and 180 days after surgery; secondary outcomes included the 30-day refill rate and the amount of opioids dispensed initially and at 30 days postoperatively. RESULTS: The sample included 65,136 patients. The percentage of patients filling a prescription beyond 90 days was similar after versus before rescheduling (absolute risk difference, -1.1%; 95% CI, -2.3% to 0.1%; P = 0.084). The authors estimated the rescheduling rule to be associated with a 45.4-mg oral morphine equivalent increase (difference-in-differences estimate; 95% CI, 34.2-56.7 mg; P < 0.001) in initial opioid dispensing, a 4.1% absolute decrease (95% CI, -5.5% to -2.7%; P < 0.001) in refills within 30 days, and a 37.7-mg oral morphine equivalent increase (95% CI, 20.6-54.8 mg; P = 0.008) in opioids dispensed within 30 days. CONCLUSIONS: Among patients treated by surgeons who frequently prescribed hydrocodone before the Drug Enforcement Agency 2014 hydrocodone rescheduling rule, rescheduling did not impact long-term opioid receipt, although it was associated with an increase in opioid dispensing within 30 days of surgery.

The Impact of Increased Hydrocodone Regulation on Opioid Prescribing in an Urban Safety-Net Health Care System.

BACKGROUND: Hydrocodone-combination analgesics were changed from Schedule III to Schedule II to discourage the prescribing of these analgesics. Our primary aim was to explore the effect of hydrocodone rescheduling on opioid prescribing within an urban safety-net health care system. METHODS AND DESIGN: Data were extracted from electronic records of ambulatory patients (N = 82,432 patients) prescribed hydrocodone-combination, codeine-combination, or tramadol opioid analgesics (N = 200,675 prescriptions) between October 6, 2013 and October 6, 2015. Data analyses modeled predicted probabilities of hydrocodone-combination prescriptions (HCPs). Chronic opioid therapy (COT) for chronic pain (ie, ≥3 opioid prescriptions/12 months) and morphine milligram equivalency (MME) levels were also examined. RESULTS: The probability of providers writing HCPs decreased significantly from pre- to postrescheduling (0.525 vs 0.158, respectively, P < .0001). However, this coincided with large probability increases in codeine-combination (0.064 vs 0.269) and tramadol prescriptions (0.412 vs 0.573). The probability of HCPs varied across physician specialty (P < .0001), patient diagnoses (P < .0001), COT versus non-COT patients (P < .0001), and patient characteristics (sex, race/ethnicity, and age; P < .05). COT patients received significantly more opioid prescriptions in the postrescheduling period (M = 4.81 vs M = 4.27; P < .0001). Patients on <20 MME/day increased slightly from pre- to postrescheduling (P < .0001). DISCUSSION: Significant declines in HCPs occurred after rescheduling; however, one third of patients prescribed opioids remained on doses ≥20 MME/day. Codeine- and tramadol-prescription probabilities increased significantly and providers may have an increased perception of safety about these medications. Physicians and health care systems must reduce their overreliance on opioids in treating pain, especially chronic pain, as all opioids incur some level of risk.
