A Balanced Approach: How Massachusetts’ Opioid Limit Law Is Reshaping Post-Operative Pain Management

Spread the science

In a recent study titled Massachusetts’ Opioid Limit Law Associated with a Reduction in Post-Operative Opioid Duration Among Orthopedic Patients, researchers delved into the impact of the 2016 Massachusetts 7-day opioid prescription limit law on post-operative prescriptions among orthopedic patients. This study is particularly significant against the backdrop of the opioid overdose epidemic and the high-risk nature of post-operative orthopedic patients for receiving prolonged, high-dosage opioid prescriptions​​.

Understanding the Context

Orthopedic surgeries often result in significant post-operative pain, making this patient group particularly vulnerable to long-term opioid use and associated risks, including overdose. In 2019, almost half of orthopedic surgeons prescribed opioids, the highest among all surgeons, with about 6% of patients still filling opioid prescriptions six months after surgery​​.

In response to the growing opioid crisis, many U.S. states, including Massachusetts as the pioneer, enacted laws to limit the duration and dosage of opioid prescriptions. Massachusetts’ law, implemented in March 2016, targeted opioid-naïve patients with acute pain conditions, including those recovering from surgeries​​.

Key Findings of the Study

The study, which analyzed data from 2014 to 2017, compared Massachusetts’ patients to a control group in New Hampshire. It found a significant impact of the 7-day limit law:

  • There was an immediate 4.23 percentage point absolute reduction and a 33.27% relative reduction in the percentage of initial opioid prescriptions exceeding seven days among Massachusetts patients compared to the control group​​.
  • This reduction was sustained; the study did not find significant changes in the trend of secondary outcomes like the total morphine milligram equivalents (MME) or daily MME. This suggests that the law effectively reduced the duration of opioid prescriptions without impacting the initiation or dosage of opioid use​​.
  • The law’s impact extended to elective, non-elective, and spine surgery patients, indicating a broader effect on prescribing practices beyond the initial target group​​.

Implications for Public Health Practice

The findings from Massachusetts’ experience provide vital insights for public health practice:

  1. Policy Impact: The 7-day limit law effectively curtailed prolonged opioid prescription practices among a high-risk group without affecting the initial opioid prescription rates or dosages. This outcome aligns with public health goals of reducing opioid misuse while not compromising pain management.
  2. Wider Applicability: The law’s impact across various types of surgeries suggests that similar policies could be effective in other states or regions, helping to mitigate the risk of long-term opioid use and potential addiction.
  3. Balancing Pain Management and Opioid Risk: The study highlights the delicate balance required in managing post-operative pain while minimizing the risk of prolonged opioid use. It underscores the need for nuanced policies adaptable to different pain levels and patient needs.


The study provides compelling evidence that carefully crafted opioid prescription laws can significantly reduce the risk of prolonged opioid use in post-operative patients without hindering effective pain management. This research offers a model for other states and healthcare systems striving to combat the opioid epidemic while ensuring adequate pain relief for patients recovering from surgeries.
