A Multi-Site Feasibility Trial of Embedded Emergency Department Physical Therapy for Dizziness

Overview

This is a multi-site feasibility trial of an embedded emergency department (ED) physical therapy care model for dizziness at two EDs in the Northwestern Medicine and University of Utah Health systems. The study intervention (embedded ED physical therapy) is a reconceptualization of the traditional outpatient physical therapy care model in which we place a physical therapist directly in the ED to initiate timely care for patients with dizziness; we previously evaluated this intervention in a single center randomized trial for low back pain. This multi-site feasibility trial will be comprised of 9 months of active intervention and 12 months of longitudinal data collection. The two sites will be parallel randomized 1:1 to receive either the embedded ED physical therapy condition (intervention, n=1) or usual care (control, n=1) via simple randomization. This trial focuses on feasibility outcomes - such as our ability to enroll participants, deliver the intervention with fidelity, and collect longitudinal patient-reported outcome data and electronic health record data.

Detailed description

After a 12-month milestone-driven planning and preparation phase, we will conduct a 21-month randomized feasibility clinical trial of the embedded ED physical therapy intervention at the Northwestern Medicine and University of Utah health systems, comprised of 9 months of active intervention and 12 months of longitudinal data collection. Two hospital EDs (Northwestern Memorial Hospital, University of Utah Hospital) will be randomized to receive either the embedded ED physical therapist intervention (treatment, n=1) or usual care (control, n=1). Following completion of the feasibility trial, the control site will receive the intervention as per standard waitlist procedures for randomized trials. A third hospital ED (Northwestern Lake Forest Hospital) will not participate in randomization or participant enrollment but will contribute baseline electronic health record data to assist in feasibility assessments for a future full-scale trial.

Interventions

• Other Embedded Emergency Department Physical Therapy
  We place a physical therapist directly in the emergency department to initiate timely care for patients with dizziness rather than waiting on an outpatient referral to physical therapy, which can often take weeks to accomplish, if ever at all. The actual techniques and approaches used by the embedded ED physical therapist in this study (e.g., exercises, maneuvers, coaching) are standard-of-care and do not involve investigational interventions, devices, or drugs.
• Other Usual Care
  Standard-of-care treatment for dizziness presenting in the emergency department

Primary outcome measures

• Longitudinal participant surveys (effectiveness): missing data rate for the Dizziness Handicap Inventory [Time frame: 12 months]
• Longitudinal participant surveys (effectiveness): screening-to-enrollment ratio [Time frame: Baseline]
• Longitudinal participant surveys (effectiveness): participant retention rate defined as completion of at least one follow-up survey. [Time frame: 12 months]
• Electronic Health Record (EHR) extraction (implementation): adoption of Emergency Department (ED) physical therapy [Time frame: Baseline]
• Electronic Health Record (EHR) extraction (implementation): fidelity of Emergency Department (ED) physical therapy [Time frame: Baseline]
• Clinician surveys before and after implementation of the intervention (implementation): Normalisation Measure Development Questionnaire (NoMAD) questionnaire scores [Time frame: 1-6 months prior to opening study to accrual and 1-6 months after the last participant enrolls at the site.]

Secondary outcome measures (7)

• Longitudinal participant surveys (effectiveness): a sum of the missing data rate for the remaining Participant Reported Outcomes (PROs) combined. [Time frame: 12 months]
• Electronic Health Record (EHR) extraction (effectiveness): rate of subsequent health care encounters. [Time frame: 12 months]
• Electronic Health Record (EHR) extraction (effectiveness): rate of prescribing sedating medications (including antihistamines and benzodiazepines) [Time frame: 12 months]
• Electronic Health Record (EHR) extraction (effectiveness): rate of advanced diagnostic imaging [Time frame: 12 months]
• Clinician surveys before and after implementation of the intervention (implementation): Acceptability of Intervention Measure (AIM) [Time frame: 1-6 months prior to opening study to accrual and 1-6 months after the last participant enrolls at the site.]
• Clinician surveys before and after implementation of the intervention (implementation): Intervention Appropriateness Measure (IAM) [Time frame: 1-6 months prior to opening study to accrual and 1-6 months after the last participant enrolls at the site.]
• Clinician surveys before and after implementation of the intervention (implementation): Feasibility of Intervention measure (FIM). [Time frame: 1-6 months prior to opening study to accrual and 1-6 months after the last participant enrolls at the site.]
