Abstract:
With the passage of the MAT act (Mainstreaming Addiction Treatment) and the MATE Act (Medication Training and Expansion), the Drug Enforcement Agency "X-waiver" program governing the office-based prescription of buprenorphine for opioid use disorder has been immediately eliminated. The move was championed by vocal organizations with a rightful concern about buprenorphine access but was opposed by most physicians. Nonetheless, buprenorphine can now be prescribed like any schedule 3 medication. Studies show that despite rising opioid overdoses, buprenorphine prescription increases have been slow to rise and are particularly absent in rural communities. The elimination of the X-waiver may theoretically improve buprenorphine prescribing rates for opioid use disorder in rural areas, by nurse practitioners and physician assistants, and by resident physicians in teaching programs. It may also help decrease discrimination against individuals with opioid use disorder in postacute-care settings like nursing homes, physical rehabilitation centers, and in prisons and jails. Concerns include the elimination of the only focused opioid use disorder education many physicians receive (X-waiver courses) and a literature base showing that interest, rather than the X-waiver itself, remains the biggest barrier to recruiting more buprenorphine prescribers. Concerns also exist over the harms of precipitated withdrawal when buprenorphine is initiated inappropriately. The change of the elimination of the X-waiver brings about a new opportunity for Family Medicine and its parent organizations to champion the inclusion of opioid use disorder treatment within the chronic disease care models well-known to our integrated care settings.

The X̄ Chart
The x̄ chart, often known as the individual control chart, is a crucial tool in statistical process control. It is designed to monitor process behavior and performance over time and is widely used in various industries to ensure that processes are operating at their optimum capacity and within specified limits.
