Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 21 to 65 years
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Who may be able to join

  • Age greater than 21 years and less than 65 years: This is a study of non-elderly adult patients.
  • Pain with onset within 7 days: Pain within seven days is the definition of acute pain that has been used in ED literature.
  • ED attending physician's judgment that patient's pain warrants IV opioids: The factors that influence the decision to use parenteral opioids are complex. An approach that is commonly taken to address the issue of patient selection in drug trials is to use a specific condition (e.g., renal colic) that would generally be thought to be appropriately treated with an opioid analgesic, thereby eliminating individual judgment about eligibility for the study. However in order to maximize the external validity of the role of opioids in the ED setting, the investigators decided to enroll patients with a variety of diagnoses, all with a complaint of acute pain. Opioids are not an appropriate treatment for all patients who present with a complaint of pain (e.g., gastroenteritis, migraine). Therefore, unless there is a restriction to patients with a specific diagnosis, either an extensive list of diagnoses and situations in which opioids are indicated must be specified, or clinical judgment needs to be used. The investigators have opted for the latter, since it most closely approximates the circumstances of clinical practice.

Who cannot join

  • Use of other opioids or tramadol within past 24 hours: to avoid introducing assembly bias related to recent opioid use, since this may affect baseline levels of pain and need for analgesics.
  • Prior adverse reaction to opioids.
  • Chronic pain syndrome: frequently recurrent or daily pain for at least 3 months results in modulation of pain perception which is thought to be due to down-regulation of pain receptors. Examples of chronic pain syndromes include sickle cell anemia, osteoarthritis, fibromyalgia, and peripheral neuropathies.
  • Alcohol intoxication: the presence of alcohol intoxication as judged by the treating physician may alter pain perception.
  • Systolic Blood Pressure <90 mm Hg: Opioids can produce peripheral vasodilation that may result in orthostatic hypotension.
  • Oxygen saturation < 95% on room air: For this study, oxygen saturation must be 95% or above on room air in order to be enrolled.
Show all 11Show fewer
  • Use of monoamine oxidase (MAO) inhibitors in past 30 days: MAO inhibitors have been reported to intensify the effects of at least one opioid drug causing anxiety, confusion and significant respiratory depression or coma.
  • C02 measurement greater than 46: In accordance with standard protocol, three subsets of patients will have their CO2 measured using a handheld capnometer prior to enrollment in the study. If the CO2 measurement is greater than 46 then the patient will be excluded from the study. The 3 subsets are as follows:
  • All patients who have a history of chronic obstructive pulmonary disease (COPD)
  • All patients who report a history of asthma together with greater than a 20 pack-year smoking history
  • All patients reporting less than a 20 pack-year smoking history who are having an asthma exacerbation

About this study

Official title: Randomized Clinical Trial Comparing Intravenous Hydromorphone to Usual Care

In this randomized controlled trial, 2 mg intravenous (IV) hydromorphone will be more efficacious than usual care (usual care is analgesic management according to the judgment of the attending physician caring for that patient) in emergency department (ED) patients aged 21-64 years. The primary efficacy outcomes are the proportion of patients in each arm who choose to forgo additional pain medication in 30 minutes of entry into the study and the change in numerical rating scale (NRS) pain scores from baseline to 30 minutes post baseline.

Read the detailed description

Patients were randomized to the 2 mg IV hydromorphone group or usual care; allocation was generated with www.randomization.com, using sealed opaque envelopes opened in sequential order by the research assistants (RAs) immediately following enrollment. Patients randomly allocated to usual care received an initial dose of IV opioid; the type and dose of which was determined by the treating emergency physician (EP). Patients in the 2 mg hydromorphone group were allocated to receive 2 mg IV hydromorphone, administered slowly over 2 to 3 minutes. All patients were placed on 2 L O2 by nasal cannula. Subjects were blinded to the treatment they were assigned. At 30 minutes, both groups were asked the following scripted question: "Do you want more pain medication?" Patients in either group who answered or otherwise indicated "yes" had their treating attending physician notified, who then decided on further pain management. Those who answered or otherwise indicated "no" did not receive additional analgesic at that time. Attending physicians were thus able to treat patients' pain in any manner they deemed fit once this primary study endpoint was reached. In addition to acquisition of the primary endpoint, patients were also asked to rate their pain on a previously validated and reproducible standard verbal NRS ranging from 0 ("no pain") through 10 ("worst pain possible") at 15, 30, 45, 60, 90, and 120 minutes following administration of the initial opioid dose at time 0. For safety reasons, patients were monitored for a total of 120 minutes (i.e., 90 minutes past the primary study endpoint) to determine adverse effects. Systolic blood pressure, heart rate, oxygen saturation, nausea, vomiting, and pruritus were assessed at baseline and at 15, 30, 45, 60, 90, and 120 minutes after initial administration of opioid. Patients who experienced oxygen desaturation (defined as < 95%) were gently aroused if sleeping, asked to take several deep breaths, and repositioned into a sitting position if they had been in a reclined position. Nasal cannula oxygen was also increased to 4 L, and the treating attending physician was notified. Subsequent management, including the use of naloxone, was per the treating attending physician's discretion.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants Who Declined Additional Medication at 30 Minutes

    Amount of patients who choose to forgo additional pain medication at 30 minutes post-baseline when asked the question, "Do you want more pain medication?"

    Measured: 30 minutes

  2. Mean Change in Pain Intensity Score From Baseline to 30 Minutes

    Pain intensity is measured on the numerical rating scale (NRS) with scores ranging from 0 ("no pain") to 10 ("worst pain imaginable"). The change in NRS score is calculated by subtracting the score at 30 minutes post treatment from the score at baseline, before treatment. The average of these values was calculated.

    Measured: 30 minutes
