About this trial
The goal of this clinical trial is to learn if buprenorphine can treat pain in older adults who have broken bones. The main questions it aims to answer are:
Is buprenorphine as effective as opioids to treat pain? Are there less side effects with buprenorphine? Researchers will compare buprenorphine and hydromorphone to see if there are differences in pain control and side effects.
Participants will be given one of the two study drugs after breaking a bone and asked about their pain scores and side effects for the next 48 hours.

Treatments tested in this trial
Buprenorphine 0.15 MG

Treatment groups
Trial outcomes
Primary outcomes
Difference in pain scores
Difference in pain scores measured on the numerical rating scale (scale of 0-10, with 10 being maximum pain and 0 being no pain), collected on arrival and measured at one hour and four hours after medication administration
Secondary outcomes
Number of patients with adverse events
Gastrointestinal symptoms such as nausea, vomiting, constipation, and diarrhea, including by inferring from antiemetic administration; respiratory depression; and delirium. Delirium will be assessed at least 8 hours after enrollment and first dose of medication and within 48 hours. Presence of delirium is determined by a positive Brief Confusional Assessment Method (bCAM) screen. Patients will also be interviewed about other adverse effects at the time of delirium assessment.
Number of patients requiring naloxone
Need for naloxone administration
Number of patients who receive rescue medications
Administration of rescue medications (yes/no)
Total oral morphine equivalents
