Investigators at the University of Michigan, Ann Arbor, found that a simple patient decision aid can be a useful tool in providing adequate postsurgical pain control to patients while reducing the number of opioid tablets in the community. The shared decision-making aid focuses on educating the patient about opioid use and engages her in an appropriate postoperative pain management plan. Results from this prospective quality improvement study were presented in a poster at the 47th AAGL Global Congress on Minimally Invasive Gynecology (Las Vegas, Nevada, November 11–15, 2018).1
Annmarie Vilkins, DO, and colleagues’ aim was to evaluate the impact of shared decision-making through the use of a patient decision aid targeting posthysterectomy pain management and opioid use. Can such a targeted strategy help decrease posthysterectomy opioid distribution in the community without compromising patient pain control or satisfaction?
The authors noted that more than 46 people die each day from an overdose involving prescription opioids.2 Studies have shown that patients actually use significantly fewer opioid tablets than the amount clinicians generally prescribe following ObGyn surgeries.3,4 Unused prescription opioid availability has the potential for accidental use or intentional misuse of the unneeded drugs by others.
Study methods
The investigators included all English-speaking patients undergoing hysterectomy for benign disease at their institution from March 1 through July 31, 2018. Data were analyzed from women undergoing laparoscopic, vaginal, or abdominal hysterectomy before (n = 195) and after (n = 177) the decision aid was implemented.
Preoperative education. In the preoperative area, patients were uniformly educated regarding postoperative pain expectations (for example, it is normal to have some pain; the goal is to manage your pain so you can function; some women do not require opioid medications after surgery), risks of opioid medications (such as dependence or addiction; misuse of leftover pills by others), adverse effects (drowsiness; confusion), and the recommended postoperative pain management schedule.
Postoperatively, pain medications included ibuprofen around the clock, acetaminophen as needed (used with caution when hydrocodone with acetaminophen was also prescribed), and opioids only if needed.
Discharge medication planning. Using a visual scale, the investigators then educated patients regarding the maximum number of opioid tablets permitted to be prescribed according to department guidelines and the average number of opioid tablets that a typical patient uses. The number of opioid tablets prescribed varied based on route of hysterectomy (laparoscopic, abdominal, or vaginal). For example, for a laparoscopic hysterectomy, the maximum allowed prescription for oxycodone was 20 tablets, while patients used an average number of 10 tablets.
The patient was then asked to choose her desired number of tablets with which she would like to be discharged.
Structured telephone calls were made to patients 2 weeks postoperatively.
Impact of the decision aid on opioid prescribing
Before implementation of the decision aid, the average number of opioid pills prescribed at discharge was 25 (median, 20–35), while that number dropped to 10 (median, 10–15) after the aid’s implementation. Similarly, the average oral morphine equivalents (OMEs) at time of discharge was 150 (interquartile range [IQR], 120–200) before decision aid implementation and 75 (IQR, 25–150) after decision aid implementation. Similar reductions in average OMEs were observed before and after the aid’s implementation across the 3 hysterectomy routes.
