Study Details

Brief summary:

Although most people recover from acute pain (such as pain caused by injury, surgery, repetitive motion, or unknown causes), many people do not fully recover and will experience chronic pain. Untreated posttraumatic stress disorder (PTSD) appears to be a key risk factor for the transition from acute pain to chronic pain. However, few published studies have addressed the issue of preventing the transition from acute to chronic pain via PTSD reduction. This project will aim to test whether trauma-related PTSD symptoms can be reduced using either Stellate Ganglion Block (SGB) treatment or Cognitive Processing Therapy (CPT), and whether reducing PTSD symptoms can prevent the transition from non-injury based acute pain to chronic pain.

Eligibility Criteria

Sex: All

Age: 18 - 70

Healthy Volunteers: Not accepted

Inclusion Criteria:

1. Age 18 to 70 years
2. Ability to read and write English sufficiently to understand and complete study questionnaires and participate in interviews
3. Presenting to the Rush ED with acute pain without debilitating trauma
4. A primary acute pain site
5. Self-reported symptoms consistent with a diagnosis of PTSD
6. People with well-controlled diabetes or HIV/AIDS with chronic neuropathic pain will be included if their acute pain complaint at ED presentation is not due to neuropathic pain
7. Individuals with a history of psychotic or bipolar disorder that is currently well managed, have been treated for the condition for at least 3 months, are able to coherently answer interview questions, and are judged by study staff to be capable of participating in study
8. Current chronic illness that involves constant or frequent pain if their acute pain complaint at ED presentation is not due to the chronic illness. (case-by-case basis)
9. Current chronic pain from various sources if their acute pain complaint at ED presentation is not related to their current chronic pain. (case-by-case basis)

Exclusion Criteria:

1. Pain intensity great enough to impair concentration or capacity to understand instructions or the nature of being invited into a study as assessed by a member of the medical staff
2. Any injury or illness that precludes their ability to understand or follow instructions as assessed by a member of the medical staff
3. Self-reported history of chronic pain on presentation to the ED or documented in the electronic medical record (case-by-case basis)
4. Pain from traumatic event that is the source of their PTSD
5. Neurological disorder
6. Blood pressure greater than 160/100 mmHg
7. Taking anticoagulants or antiplatelet drugs other than aspirin
8. Pregnancy
9. Current alcohol or substance dependence
10. Anything that precludes interventions from being successful.
11. We will exclude people who are being treated for chronic or significant diseases such as rheumatoid disease, current influenza that may manifest temporary flu- related pain, and heart disease.

Interventions and Outcome Measures

Arms

active comparator: Stellate Ganglion Block Treatment

Participants randomly assigned to the Stellate Ganglion Block (SGB) condition will receive 2 SGB treatments separated by 2 weeks.

active comparator: Cognitive Processing Therapy

Participants randomly assigned to the Cognitive Processing Therapy (CPT) condition will receive 1-week massed CPT treatment consisting of 10 CPT sessions given within a single 5-day period via telehealth.

no intervention: Usual Care

Participants randomly assigned to the Usual Care condition will not receive any active intervention.

Interventions

Stellate Ganglion Block

Stellate Ganglion Block (SGB) procedure involves an injection of a local anesthetic (0.5% ropivacaine) around the stellate ganglion (a bundle of nerves located at the base of the neck) to block the transmission of pain signals. The SGB injection is administered by an anesthesiologist.

Cognitive Processing Therapy

Cognitive Processing Therapy (CPT) is a form of trauma-based talk therapy that will be conducted by clinical therapists. CPT can help people identify and challenge unhelpful trauma-related beliefs about themselves, others, and the world.

Primary outcome measure

  • Change in Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Intensity [ Time Frame: Through study completion, for an average of 6 months ]
  • Change in PTSD Checklist for Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (PCL-5) Self-Reported PTSD Symptoms [ Time Frame: Through study completion, for an average of 6 months ]
