An interventional study of PAC-plan in Opioid Use, Injury Traumatic and Pain, Postoperative, sponsored by University of Oslo. Active, not recruiting at 1 site in Norway. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-05-08.
Sponsored by University of Oslo · Not applicable, Interventional, and Supportive care
This clinical trial aims to lower the number of people who use opioids and improve the quality of health in patients who have experienced accidental injury by implementing a Pain and Coordination Plan (PAC-plan). The PAC-plan will be given upon discharge from the hospital.
The main questions this study aims to answer are:
Participants will be randomly assigned to the PAC-plan or usual care. The PAC-plan includes:
Participants in both groups will be asked to answer questionnaires about their health at discharge, and at 6 and 52 weeks after discharge from the hospital. In addition, the researchers will use data from the Norwegian Prescription Database to measure use of opioids and other relevant drugs, the Norwegian Patient Registry (NPR) and the Norwegian Registry for Primary Health Care (KPR) for the use of health care services and Statistics Norway for data on sick leave and other social security benefits.
Introduction: Patients experiencing serious injuries are at risk of developing long-term opioid use, yet many don't receive plans for opioid reduction when discharged from the hospital. General Practitioners (GPs) also experience insufficient communication from the hospital on pain management plans. Opioids are often essential for managing acute pain in patients following serious injuries. However, it is crucial to prioritize safe and appropriate pain management in subsequent phases. The opioid epidemic in the USA, characterized by opioid use disorders and addiction, has resulted in high mortality rates and a public health crisis. In 2017, opioid dependence outside the USA was estimated to account for over 1% of age-standardized years lived with disability in 135 countries. Considering the devastating impact of the opioid epidemic in the USA, it is imperative to draw lessons from these experiences and implement preventive measures to avoid a similar crisis in other countries.
Aim: This study aims to explore if a Pain and Coordination Plan (PAC-plan) for patients after accidental injury can reduce opioid use and improve quality of life, and if the intervention is cost-effective.
Methods: The study is designed as a prospective randomized controlled trial (RCT) to evaluate the effect of a PAC-plan. The PAC-plan consists of three main elements: an opioid management plan upon discharge from the hospital, an appointment with the participant's regular GP within 2-4 weeks after discharge and an opportunity for increased collaboration between GP and hospital specialists.
Patients will be recruited from the Division of orthopaedic surgery, Oslo University Hospital (OUH), Norway. OUH is a highly specialized hospital in charge of extensive regional and local hospital assignments in the South-Eastern Health region in Norway and is described as a level 1 trauma centre. The primary outcome is oral morphine equivalent (OMEQ) consumption 6 weeks after discharge. Secondary outcome measures are OMEQ 52 weeks after discharge. In addition, registry-based OMEQ and other addictive drugs, pain, health-related quality of life (HRQoL) and other Patient-reported outcome measures (PROMs) at 6 and 52 weeks, and finally use of health care services and sick leave. The registry-based OMEQ will be collected from the Norwegian Prescription Database (NorPD). Data will also be collected from the the Norwegian Patient Registry (NPR), the Norwegian Patient Registry (NPR), the Norwegian Registry for Primary Health Care (KPR) and Statistics Norway.

Exclusion Criteria:
The patients receive a Pain- and Coordination plan (PAC-plan) at discharge from the hospital. The PAC-plan includes: * Upon discharge, patients have a patient-centered conversation and receive written information covering patient education on opioids, a tapering plan, and a plan for contact and follow-up with the general practitioner. The information is based on the Norwegian National Guide for Addictive Medications. * Before discharge, patients are scheduled an appointment with the GP, preferably within the first 2 weeks (2-4 weeks), for a follow-up regarding the injury and pain management. * The GP is invited to maintain contact with the study nurse at the hospital for one year. The general practitioner can call for consultation with the study nurse, and if necessary, be connected with relevant medical specialists for advice and eventually further follow-up.
Other: PAC-plan
Treatment and follow-up as usual.
The participants will be asked to complete electronic questionnaires at baseline, and at 6 weeks and 52 weeks after discharge from the hospital. The completion of these questionnaires will take place during the 6-week follow-up appointment at the hospital (a standard follow-up for all patients undergoing surgery at the Division of Orthopedic Surgery, Oslo University Hospital, Norway). Additionally, participants will be invited for a phone-based follow-up appointment with the study coordinator 52 weeks after discharge. The participants will receive the questionnaires electronically via SMS or email. If electronic options are not feasible, data can be collected through paper questionnaires sent by mail. Data will not be directly obtained from general practitioners.

EQ-5D-5L (EuroQol, 5 dimensions, 5 levels) for health-related quality of life
Health-related quality of life measured with the EQ-5D-5L. The EQ-5D-5L consists of two parts: the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS). The descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. The EQ visual analogue scale (EQ VAS) records the patient's self-rated health on a VAS ranging from 0 to 100, with higher scores indicating better self-reported health.

HUNT (the Nord-Trøndelag health study) physical activity questionnaire (HUNT 1 PA-Q)
The HUNT 1 PA-Q consists of three sets of questions addressing the average number of times exercising each week, the average intensity and average hours each time. Each set of questions has five, three, or four response choices, respectively. The HUNT 1 PA-Q measures physical exercise as the product of average frequency (0.0-5.0 points), duration (0.10-1.00 points) and intensity (1-3 points) each week, giving an index ranging from 0.00 to 15.00, with 15.00 as the best score

Cost-effectiveness
The cost-effectiveness of the intervention will be assessed by the incremental cost-effectiveness ratio (ICER), defined by the incremental costs (the difference in costs between the intervention group and the control group) per quality-adjusted life year (QALY) gained. In the health economic analysis, we will also present differences in costs associated with healthcare service consumption (based on data from the Norwegian Prescription Database (NorPD), the Norwegian Patient Registry (NPR), and the Norwegian Registry for Primary Health Care (KPR), as well as differences in sick leave and disability benefits (using data from Statistics Norway).
