Effects of a Revision to the Standard Admission Order Set on Laxative Prescribing for Opioid-Induced Constipation.

Purpose: Opioid-induced constipation (OIC) is highly prevalent in patients with cancer-related pain on opioid analgesics and has negative consequences on physical and psychological well-being and quality of life. Oncology clinical practice guidelines recommend the use of osmotic and stimulant laxatives for the prevention and management of opioid-induced constipation, not stool softeners such as docusate sodium. Prescribing practices continue to fall behind these recommendations.

Methods: This quality improvement project revised the laxative options available in the standard admission order set in the electronic medical record. Specifically, docusate sodium was removed and replaced with senna and polyethylene glycol 3350.

Results: A total of 2,742 patient admissions preintervention were compared to 2,752 admissions postintervention. The number of orders for docusate ( < .001) and docusate-senna ( = .002) orders decreased significantly after the intervention, in addition to the number of OIC diagnoses ( < .001). However, the number of orders for polyethylene glycol ( = .559), senna ( = .582), other laxatives ( = .245), or functional bowel disorder medications ( = .533) did not change significantly. No significant differences were observed in the frequency of laxative orders placed within 24 hours of an opioid order, number of laxatives prescribed at discharge, admissions related to bowel-related complications, or length of stay.

Conclusions: Interventions utilizing the electronic medical record can facilitate evidence-based management of OIC. Development of clinical practice guidelines and tailoring these interventions further is needed to adapt this approach at other institutions and sustain practice change.
