Reducing opioid prescribing on discharge after orthopedic surgery: Does a guideline improve opioid prescribing...

To investigate adherence to discharge advice in a prescription opioid prescribing guideline (GL) post-orthopedic surgery.

The guideline in draft form was introduced in February 2018. To assess longer-term adherence to discharge advice and to understand which components of that advice were adhered to, regular audits of discharge prescribing were performed after formal GL launch in February 2019, a year after the draft of the GL had been available. The post-GL audit was conducted for three months (March to May 2019) and results reviewed. When these audit results showed a need for improvement in prescribing practice, a 1-month education "booster" named prescription opioid practice improvement safe opioid supply (POPI SOS) took place. Audits for a further 3 months (July to Sept 2019) were then carried out to ascertain whether the additional effort improved adherence to the guideline.

On average, adherence to all elements of the guideline was low at only 23.1 percent at 12 months post-draft GL and 1 month after its formal launch. After POPI SOS, a statistically significant improvement was achieved with an average increase in adherence to 52.5 percent (ρ < 0.001). Greatest improvement was seen in the percentage of patients discharged with an opioid plan included in the discharge summary, increasing from 35.8 to 77.7 percent (ρ < 0.001). The second significant improvement observed was in the supply of opioids being limited to four days or less, an increase from 38.1 to 61.9 percent (ρ < 0.001).

Introduction of the guideline was not sufficient to promote sustained change in practice. Ongoing monitoring and education were required for its implementation. These findings highlight that comprehensive, locally adapted, evidence-based opioid stewardship is needed to increase the safety of patients and the community in relation to opioid therapy.
