Brief summary

The Prehospital Analgesia INtervention trial (PAIN) is a proposed 4 year (3-year enrollment) multicenter, prehospital, randomized, double-blind, clinical trial that will enroll approximately 994 patients at select LITES Network sites. The objective is to perform a prospective, interventional, randomized trial among prehospital trauma patients with compensated shock (SI≥0.9 or HR ≥115) and an indication for pain management, comparing patient centered outcomes following prehospital administration of ketamine hydrochloride versus fentanyl citrate.

Interventions

DRUGKetamine Hydrochloride

ketamine hydrochloride 2.5mg/ml packaged in pre-filled syringe

DRUGFentanyl Citrate

fentanyl citrate 10mcg/ml packaged in pre-filled syringe

Prehospital pain assessment following analgesiafrom initial administration of PAIN study prehospital analgesia through hospital arrivalprehospital pain assessment using Numeric Rating Scale (NRS)/Critical Care Pain Observational Tool (CPOT) scores. For Numeric Rating Scale, the patient rates their pain on a scale of 0 to 10 where 0 is no pain and 10 is the worst pain. The Critical Care Pain Observation Tool is used for patients who are intubated and cannot verbalize a pain score. Medical staff will observe the patient's behavior and score the patient's pain on a scale of 0 to 10, where 0 is no pain and 10 is the worst pain.
Trauma bay arrival pain scorescore assessed at time of arrival to trauma baypain assessment using Numeric Rating Scale (NRS)/Critical Care Pain Observation Tool (CPOT) score. For Numeric Rating Scale, patients rate their pain on a scale of 0 to 10 where 0 is no pain and 10 is the worst pain. The Critical Care Pain Observation Tool is used for patients who are intubated and cannot verbalize a pain score. A nurse will observe behavior and score the patient's pain on a scale of 0 to 10 where 0 is no pain and 10 is the worst pain.

For Numeric Rating Scale, the patient rates their pain on a scale of 0 to 10 where 0 is no pain and 10 is the worst pain. The Critical Care Pain Observation Tool is used for patients who are intubated and cannot verbalize a pain score.

Long term opioid use3 months (+/- 1 month) and 6 months (+/- 1 month) following trauma admissionlong term opioid use assessed at 3 and 6 months. Patients who consent to further participation will be contacted to determine if they continued to use opioids (yes/no) at 3 and 6 months following trauma admission

Baseline Pain/Anxiety/PTSD screening0 hours to 2 weeks from time of hospital admissionA subset of patients who consent to further participation will be assessed for Anxiety/PTSD using the Four-Item Patient Health Questionnaire (PHQ-4) for anxiety and depression, a two item pain severity scale (0=no pain to 10=worst pain), and the Injured Trauma Survivor Screen (ITSS)
Long term (6 month) outcome6 months +/- 1 month following trauma admissionA subset of patients who consent to further participation will be assessed for anxiety/depression/PTSD symptoms using the following tools: Generalized Anxiety Disorder (GAD-7), 8 item Patient Health Questionnaire (PHQ-8), and 8 item PTSD checklist (PCL-5)
Hypoxiafrom initial administration of PAIN prehospital analgesia through hospital arrivalincidence of hypoxia in the prehospital environment
Long Term Pain AssessmentAt 3 and 6 months (+/- 1 month) after hospital arrivalA subset of patients who consent to further participation will be assessed for long term pain using a modified Brief Pain Inventory (numerical scale rating 0-10)
