Brief Summary

Opioid analgesics are commonly prescribed addictive narcotics intended for the treatment of pain. Inappropriate prescription of opioids in quantities and for conditions which lack clinical evidence contributes to the risk of misuse and addiction. The majority of opioid prescriptions are written by physicians (general practitioners) in primary health care (PHC). PHC is thus an important setting for efforts to encourage the safe and appropriate prescription of opioids. Increasing knowledge of pain treatment recommendations, risks of opioids, and guidelines for the prescription of opioids may decrease inappropriate prescription, and thereby risk of tolerance, dependence, and addiction.

Study Arms (3)

Educational intervention with prescription feedback

EXPERIMENTAL

Healthcare personnel will participate in a brief educational intervention with information regarding treatment guidelines, recommendations, and risks of prescribing opioids. The presentation will include benchmarking on clinic opioid prescription patterns compared to other primary health centers, followed by targeted feedback on prescription patterns over the subsequent 12 months. Standardized materials will be provided, including a patient-provider agreement, outline of a patient treatment plan, and recommendations of how shared routines at the center can be improved.

Behavioral: Educational intervention and prescription feedback

Written information on guidelines

ACTIVE COMPARATOR

The manager at each PHC center in the active control group will receive written information on treatment guidelines for pain management. These centers will not receive the intervention, consisting of the onsite educational visit and targeted prescription feedback.

Behavioral: General information on treatment guidelines

Standard care

NO INTERVENTION

The passive control group will consist of PHC centers that met the eligibility criteria for the study but did not actively participate in the study. Care as usual will proceed at the centers. Prescription data will be gathered directly from regional registers and databases; thus there will be no need to communicate directly with the centers. This arm will be used only if the General Data Protection Regulation continues to allow access to regional registers and databases in primary health care.

Interventions

Brief educational intervention and patient and provider materials regarding prescription of opioids. Subsequent feedback on clinic prescription of opioids over 12 months.

Educational intervention with prescription feedback

Written information on guidelines and recommendations regarding prescription of opioids.
