5 Clinical Trials for Various Conditions
STUDY SYNOPSIS Objectives The primary objective is to estimate the proportion of subjects who report clinically important reductions in pain score (defined as 2 points on a 0-10 verbal numerical rating scale) after receiving a single dose of fentanyl (per local standard) with or without intranasal (IN) ketamine (50mg) prior to hospital arrival for the treatment of acute traumatic pain. Design and Outcomes This protocol describes two linked studies conducted as a prospective, randomized, placebo-controlled single-site clinical trial. The primary study has a primary outcome variable of reduction of reported pain of at least 2 points (on the 0-10 Verbal Numerical Rating Scale1,2) when comparing the pretreatment pain score to the pain score obtained upon reassessment 30 minutes after medication administration; secondary outcomes of the primary trial include reduction of reported pain at Emergency Department (ED) arrival; the incidence of adverse events; additional opiate requirements prior to ED arrival and in the first three hours of ED care. The secondary study explores secondary outcomes including: development of chronic pain (measured by the Brief Pain Inventory,3) or post-traumatic stress disorder (measured by the PTSD Checklist for DSM-54) and overall satisfaction with life (measured by the Satisfaction With Life Scale5) at 90-days after injury. Interventions and Duration Adult men who qualify for prehospital pain treatment under paramedic standing orders will be screened for inclusion and will undergo informed consent for the primary trial. After ED arrival, subjects who consented for the primary trial will be approached for inclusion in the secondary trial. Prehospital consent for primary trial enrollment and study drug administration will occur concurrent with receiving a single dose of fentanyl (IV, IM or IN per current standard practice). Consenting subjects will be 1:1 randomized to receive either 50mg IN ketamine or IN saline placebo. Pain will be rated on a 0-10 scale by the subject prior to treatment and at 30 minutes following treatment and will receive further pain assessments at 30 minute intervals for the first three hours of their ED care. Additional pain medications given prior to hospital arrival and within the first three hours of ED care will also be recorded. The primary outcome of the primary trial will be reduction in baseline pain between the pretreatment measurement and 30 minutes after medication administration. Consent for the secondary trial will be obtained for the additional baseline assessments for secondary outcomes and at 90-day follow-up. Overall satisfaction with life and symptoms of PTSD and chronic pain will be assessed before hospital disposition (in-person) and via phone follow-up at 90-days (+/- 14 days) after injury.The subject will have the option to complete the 90-day follow-up assessments in-person if it coincides with a clinical appointment on the medical campus. Sample size and Power We consider a 2-point reduction in pain to be clinically significant, and thus our primary outcome for the primary trial will compare the proportion of subjects achieving a 2-point reduction in pain at 30 minutes post-medication administration between the treatment group and the control group. Sample size considerations are based on this primary analysis. To test the hypothesis that the proportion of those treated with fentanyl alone that have at least a 2-point reduction in their pain will be lower than the proportion of those treated with the combination of fentanyl and single-dose ketamine who have a 2-point reduction in their pain, we will use a chi-square test (or the Fisher's Exact Test if appropriate). An intent to treat approach will be used. We expect the response rate in the two groups to be 40% and 60%, respectively. These estimates are based on the response rates in a study comparing pain management efficacy between subjects treated with morphine alone and morphine plus ketamine.6 With this magnitude of effect, a sample size of 97 per group will have 80% power to detect the difference between the two groups when the critical level of significance is set to 5%. To allow for subject drop-out, protocol deviations, and missing outcome data, we plan to enroll an additional 15% in each arm, for a total of 224 subjects.
Single center, non-blinded, randomized controlled trial. Enrollment is based on ≥50 MME within 24 hours of admission, followed by a 24 hour screening/randomization window and a participation period extending through the acute hospitalization period. A total of 122 adult patients admitted with a traumatic injury will be randomized 1:1 across 2 study arms: adjunctive dronabinol or systemic analgesics only. Patients randomized to the dronabinol arm should receive their first dose within 12 hours of randomization; patients will also receive PRN as needed systemic analgesics for pain. Except for the analgesia protocol, all other interventions will be equivalent for participants in both arms. The clinical effects of analgesia treatment arm will be evaluated during the acute hospitalization (hospital admission through discharge or death). The primary efficacy endpoint will be assessed starting at 48 hours after randomization and carried through to discharge.
Acute traumatic rib fractures are a common issue for patients of trauma surgeons. They inflict substantial morbidity, the most dreaded and consequential of which are pulmonary complications. While these fractures are often treated non-operatively, there is a continued need for effective adjuvant treatments to improve rib fracture pain and outcomes. Prior studies have evaluated outcome measures for traumatic rib fractures that include respiratory failure, tracheostomy requirement, ICU length of stay, hospital length of stay, narcotic requirement, daily maximum incentive spirometry volume, pneumonia, and mortality . Rib belts, which have been present since at least 1945, have long been used to provide pain relief via chest wall stabilization \[3\]. However there is an extreme paucity of literature regarding their clinical efficacy, and their use has largely been abandoned due to concerns that they may have been overly constricting and resulted in poorer respiratory (pulmonary/breathing) outcomes. Newer generation rib belts are more elastic and theoretically less constricting than their earlier generation predecessors, however their clinical efficacy has not been yet demonstrated. The investigators will therefore plan to perform a prospective trial to determine if these rib strapping devices are effective clinical tools in the traumatic rib fracture population. The goal of the study is institutional quality improvement, to determine if the investigators see benefit of these devices for the pain management of our trauma population. The investigators will also conduct this as a pilot trial for hopeful future research applications, however the overall goal is institutional improvement. Patients determined to be eligible for the study by the admitting physician (and per the previously defined criteria) will be recruited to enroll in the project within the first 24 hours of their hospital admission. Recruited patients will be offered the opportunity to consent to enrollment in the study and will be assigned by the study team into either the intervention (RibFx belt +current standard of care) or control (current standard of care) arm in a quasi-experimental prospective design: untreated control group with dependent pretest and posttest samples. In this manner, the intervention arm will be both compared to themselves (pretest vs. posttests) as well as to a control group not exposed to the intervention. The relevant study materials will be included in their paper (physical) and electronic chart. Patients upon enrollment in the study will undergo an initial assessment that will include their baseline pain scores, narcotic consumption, incentive spirometry scores, and the subjective self-reported results of their questionnaire (the pre-test questionnaire- see attached). Patients will continue to be scored on objective (incentive spirometry results, opioid pain medicine consumption) and subjective variables (pain scores) during their hospital course. Between 24-48 hours after enrollment, they will be prompted to again complete a similar 2nd questionnaire post-test (if they are discharged from the hospital at this point in the time course, they will be sent home with the questionnaire and prompted to complete it at home). At their follow up appointment in trauma clinic (which will be coordinated by the research team to be as close as possible to 3 weeks post injury), they will have the opportunity to again voluntarily complete a final short questionnaires (post-test) that assess their pain control and respiratory function over the last 3 weeks. At this point, their involvement in the trial will be complete. Patients themselves will play an active role in data collection during the trial, and will be instructed and prompted in how to do so. Patients will be expected to fill out a worksheet on a daily basis, both while inpatient and after discharge, on their daily incentive spirometry scores as well as their minimum and maximum pain scale scores. This will be used to supplement the survey or questionnaire data, as well as the objective data from the electronic medical record. The investigators will ultimately compare groups using a quasi-experimental design as follows: Untreated control group with dependent pretest and posttest samples. This will allow for a direct comparison of patient to patient within the intervention arm (patient pretest result serving as control compared to posttest result) . To observe for temporal variability, their will be a control group with no intervention as well (no rib belt worn) , however the principle aim of the study is the comparison of patients to themselves in a pre-test, post-test fashion.
Severe and refractory pain after acute injury is a known-risk factor for chronic opioid use disorder. In this study, the investigators will use Virtual Reality (VR) immersion as a non-pharmacological adjunct to treat pain associated with acute traumatic injuries, including traumatic brain injury. The investigators hypothesize that VR therapy will decrease pain and reduce opioid use in patients with acute traumatic injuries, including TBI.
Using a retrospective review of records, we will conduct a multivariate analysis to examine the relationship between exposure to ketamine, as an analgesic agent in combat related trauma care, the use of additional opioid pain medications, and patient reported pain levels.
