Fig. 1

The networks of physicians and nurse practitioners that had at least 20 SUD clients between March 28, 2020, and August 31, 2021, colored by their PSS status at 3 separate months

Abbreviations: SUD, substance use disorder; PSS, prescribed safer supply. A connection between two prescribers is kept if the weight (number of shared clients) was in the top 20% of connections for both prescribers. This requirement, along with SUD client load, was only considered for ease of display purposes. Each month displays the cumulative number of active PSS prescribers by the end of the month. Those that are currently prescribing PSS are displayed in pink. Those that prescribed PSS in previous months, but not the current month, are displayed in green. Non-PSS prescribers with SUD clients are displayed in black
