Influence of provider type on chronic pain prescribing patterns A systematic review.

BACKGROUND: Chronic pain affects 100 million Americans and is most often treated in primary care, where the health care provider shortage remains a challenge. Nurse practitioners (NPs) represent a growing solution, yet their patterns of chronic pain management are understudied. Additionally, prescriptive authority limitations in many states limit NPs from prescribing opioids and often exist due to concerns of NP-driven opioid overprescribing. Little evidence on NP pain management prescribing patterns exists to address these issues. OBJECTIVE: Systematic review, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, to examine opioid and nonopioid prescribing patterns of physicians, NPs, and physician assistants (PAs) in primary care. Eligible studies scored ≥60% on the Joanna Briggs Institute Critical Appraisal checklist. DATA SOURCES: Searches within PubMed, Embase, CINAHL, and Web of Science. CONCLUSIONS: Three themes were elucidated: 1) opioid prescribing in primary care, 2) similarities and differences in opioid prescribing by provider type, and 3) nonopioid pain management strategies. All provider groups had similar opioid prescribing patterns, although NPs and PAs may be slightly less likely to prescribe opioids than physicians. Although some studies suggested that NPs/PAs had higher opioid prescribing rates compared with physicians, methodological flaws may undermine these conclusions. Evidence is also lacking on nonopioid prescribing patterns across disciplines. IMPLICATIONS FOR PRACTICE: Nurse practitioner/PA prescriptive authority limitations may not be as effective of a solution for addressing opioid overprescribing as transdisciplinary interventions targeting the highest subset of opioid prescribers. Future research should examine prescribing patterns of nonopioid, including nonpharmacologic, therapies.
