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) and an indication for pain management, comparing patient centered outcomes following prehospital administration of ketamine hydrochloride versus fentanyl citrate.

GroupInterventionDescription
Ketamine HydrochlorideKetamine Hydrochloride2 blinded doses 2.5mg/ml ketamine hydrochloride in separately sealed pre-filled syringes Subjects will be administered the first dose over approximately 2 minutes via slow IV push. Pain assessment following administration will be obtained and recorded every 15 minutes. Redosing may occur after approximately 15 minutes if the subject has a qualifying pain score, there are no contraindications to pain medication per local protocol, and no exclusion criteria have been met.
Fentanyl CitrateFentanyl Citrate2 blinded doses 10mcg/ml in separately sealed pre-filled syringes Subjects will be administered the first dose over approximately 2 minutes via slow IV push. Pain assessment following administration will be obtained and recorded every 15 minutes. Redosing may occur after approximately 15 minutes if the subject has a qualifying pain score, there are no contraindications to pain medication per local protocol, and no exclusion criteria have been met.
Primary Outcome Measures

24-hour mortalitytrauma bay arrival through 24 hours

All cause mortality within 24 hours from time of trauma bay arrival

Secondary Outcome Measures
NameTimeMethod
Hypotensionfrom initial administration of PAIN study prehospital analgesia through hospital arrival

incidence of hypotension in the prehospital environment

Need for airway managementfrom initial administration of PAIN study prehospital analgesia through hospital arrival

need for airway management in the prehospital environment

Number of analgesic doses necessary to reduce pain level to <5 NRS or CPOT less than 2from initial administration of PAIN study prehospital analgesia through hospital arrival

Number of analgesic doses necessary to reduce pain level to \<5 on Numeric Rating Scale or less than 2 on Critical Care Pain Observation Tool. 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. 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.

Prehospital pain assessment following analgesiafrom initial administration of PAIN study prehospital analgesia through hospital arrival

prehospital 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.

Hypoxiafrom initial administration of PAIN prehospital analgesia through hospital arrival

incidence of hypoxia in the prehospital environment

Hospital length of stayfrom time of hospital admission to discharge

number of days recorded to the first decimal from hospital admission to discharge up to 30 days

Trauma bay arrival pain scorescore assessed at time of arrival to trauma bay

pain 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.

Long term opioid use3 months (+/- 1 month) and 6 months (+/- 1 month) following trauma admission

long 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

Incidence of prehospital adverse eventsfrom initial administration of PAIN study prehospital analgesia through hospital arrival

Incidence of adverse events of allergic reaction, emergence, laryngospasm, dysphoria, pruritus, and nausea

Baseline Pain/Anxiety/PTSD screening0 hours to 2 weeks from time of hospital admission

A 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)

Intensive Care Unit free daysfrom administration of PAIN study prehospital analgesia through hospital discharge or death up to 30 days

number of days recorded to the first decimal spent admitted to the Intensive Care Unit subtracted rom 30

Long term (6 month) outcome6 months +/- 1 month following trauma admission

A 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)

Long Term Pain AssessmentAt 3 and 6 months (+/- 1 month) after hospital arrival

A 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)
