Prevention of Opioid Use Disorder After Surgery

Description

In this study, we will enroll patients who are both opioid-nave and non-nave who have undergone orthopedic surgery. To minimize contamination and best evaluate implementation, we will conduct a before-after study. The intervention will consist of four main components: 1) pharmacist-led discharge counseling and communication, 2) discharge order sets, 3) post-discharge pain management follow-up visits; and 4) a patient engagement pain management app. The intervention will last for 6 months following hospital discharge. We plan to enroll 270 patients over a 6-month period to demonstrate the feasibility of the intervention and provide reasonable precision on an effect size to inform power calculations on a subsequent larger scale clinical trial. During implementation, we will measure intervention fidelity and conduct qualitative interviews of stakeholders regarding facilitators and barriers to implementation. Throughout the study, we will engage a patient-family advisory council, other stakeholders, and a Steering Committee and Working Group to guide development and refinement of the intervention, execution of the implementation and evaluation plan, and the communication plan.

Specific Aims:

• Aim 1: To design and implement a multi-faceted intervention (MOPP) to minimize persistent post-operative opioid use while providing adequate analgesia in patients who are status post major orthopedic surgery.
• Aim 2: To pilot test and evaluate the efficacy of MOPP on preventing persistent postoperative opioid use while maintaining adequate analgesia and functional status.
• Aim 3: To evaluate the feasibility and the success of implementation of MOPP and identify barriers to and facilitators of implementation by using mixed methods and the Consolidated Framework for Implementation Research (CFIR).

In the first 3 months of the study, patients will be assigned to usual care, including 1) multimodal analgesia after surgery; 2) unit-based pharmacists as available to monitor the appropriateness of inpatient medication orders, including opioids; 3) the standard discharge medication reconciliation module in the electronic health record (EHR) that compares preadmission and current inpatient medications to facilitate writing of safe medication orders; 4) general guidelines to limit the dose and duration of discharge opioids and to council patients about tapering opioids at home and to stop them by 4-6 weeks post-operatively unless instructed otherwise; and 5) standard follow-up in the outpatient orthopedics clinic within a time frame judged to be appropriate by each inpatient team. In months 4-6 of the study, patients will be assigned to the intervention. The intervention, which we will refer to as MOPP, will consist of four complementary components, as explained below. Each of these is in addition to usual care, as described above.

1. Pharmacist-Led Discharge Counseling and Communication: Based on previously designed and evaluated interventions, an inpatient pharmacist will visit each intervention patient on two occasions: 1) An initial intake visit to screen for previous barriers to safe medication use, including lack of understanding of medication regimens, non-adherence, previous side effects, prior substance use disorder or current misuse of substances other than opioids, and lack of monitoring; 2) Prior to discharge and after the discharge opioid regimen has been determined, to provide counseling regarding safe medication use after discharge, address any of the barriers identified from the intake visit, and specifically cover several topics related to safe opioid use.
2. Discharge Order Sets: One of the challenges to opioid safety following surgery is the large variation in the dose and duration of opioids prescribed at hospital discharge. Therefore, the first step in developing a discharge order set will be generating consensus among the orthopedic surgeons for a recommended dose and duration of opioids for each commonly performed orthopedic surgery. Following this standardization process, we will work with Partners Information Systems to create a discharge order set for all orthopedic patients. It will include embedded decision support where providers can enter the orthopedic surgery type and receive the recommended discharge opioid regimen. Ordering providers will still be able to prescribe doses, frequencies, and durations other than the recommended amount, but the order set will provide a default.
3. Post-Discharge Pain Management Follow-Up: We've chosen to utilize a clinical pharmacist trained in the principles of safe opioid use and pain management to serve as the outpatient pain management follow-up clinician. Follow-up will take place in the outpatient orthopedics department so that patients can see this follow-up clinician as part of already scheduled visits with the orthopedic surgeon and staff after returning home. During the initial post-discharge visit, the focus will be on pain control, functional status, use of opioids and other analgesics, and screening for any possible misuse of opioids. Based on this information, the pharmacist will work with the patient's orthopedist on an action plan, including changes to the patient's opioid regimen, plans for tapers or discontinuation, etc. If there are concerns for development of OUD, then proper referrals and communication will be made to the outpatient addiction psychiatry service. Finally, additional office visits and/or follow-up phone calls will be scheduled as needed. We will maintain an electronic registry of all the patients in the intervention arm so the outpatient pharmacist can track all patients who may have been lost to follow-up, readmitted to the hospital, or have concerning opioid orders, and intervene as necessary.
4. Patient Engagement Pain Management App: Based on the version already created for patients with chronic opioid use, the app will be designed to collect and communicate patient-reported outcomes regarding pain management after discharge. Using the app, patients will be able to rate their current pain, including its effects on sleep, function, and mood, and whether their pain is improving or getting worse. We also plan to link the app to the patient's currently prescribed analgesic regimen so that patients can quickly record how they are taking their medications (compared with how they are prescribed). Patients will also have the ability to securely communicate with their outpatient pain management pharmacist for concerns or questions. The research staff will check the server daily for 2-way messages and link the data to the electronic medical record. Other modifications, including a Spanish version and changes unique to this post-orthopedic surgery patient population, will be made during the first 9 months of the study period based on user input and pilot testing.
