Medication assisted treatment (MAT) is an evidence-based solution to combatting opioid use disorder (OUD); however, MAT is largely unavailable in rural areas. This study investigated clinician and staff perceptions related to OUD and MAT, in particular, buprenorphine treatment, in rural primary care practices. In this qualitative study, we interviewed staff members from 42 practices and analyzed the data using a grounded hermeneutic editing approach. Four key themes emerged: 1) policies and procedures to reduce opioid prescribing were already in place, 2) there was an emotional toll to treating "those types" of patients, 3) there is a lack of local resources for help with chronic pain and buprenorphine treatment, and 4) there is a strong desire to help local patients and community members but hesitancy to engage in buprenorphine treatment. Although there was almost no provision of MAT, many practices were interested in learning more to help their communities.

Since its adoption as a treatment for neuropathic pain in the 1960s, radiofrequency ablation (RFA) has continued to gain popularity for the management of various pain etiologies. Although RFA is considered to be a safe procedure, post-neurotomy neuritis (PNN), a neuropathic-type pain, is one of the most common side effects. Due to the increasing recognition of PNN, some providers have attempted to mitigate the risk of PNN by injecting local corticosteroids at the site of RFA following the procedure. Recent studies have generally concluded that corticosteroids do not protect against the development of PNN, however, they have been limited by their retrospective study designs and the low incidence of PNN.

Buprenorphine (BUP) can be a safe and effective alternative to traditional opioids for many patients with chronic pain. For patients on higher doses of opioids, rotation to BUP is complicated by the requirement of an opioid-free interval or withdrawal during the transition. Microdosing inductions, in which BUP is gradually titrated, while full agonist opioids are continued, are a viable alternative to traditional inductions. The objective of this article is to review the current literature on BUP microdosing induction, with a focus on patients using opioids for pain. A literature review of the PubMed database was performed in the United States on articles published from inception to May 2021. A total of 34 publications were included. The most commonly utilized microdosing strategy involved administering divided doses of sublingual (SL) products marketed for opioid use disorder treatment, with 25 (73.5%) articles reporting use of partial SL tablets or films (ranging from 1/8 to 1/2 of a 2 mg product) at some point during the induction. Transdermal patches, low-dose SL BUP available in Europe, intravenous BUP, and buccal BUP have also been used. Beyond the products used, the speed of the microinduction, setting, final BUP dosing, and management of concomitant full agonists vary widely in the literature. Microdosing regimens should be individualized based on local guidelines and patient-specific factors. Further studies comparing the safety and efficacy of different protocols are warranted.
