A Multi-Site Feasibility Trial of Embedded Emergency Department Physical Therapy for Dizziness (FEED-PT)

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.

Study Overview

• Status: Recruiting
• Conditions: Dizziness
• Intervention / Treatment: Other: Embedded Emergency Department Physical Therapy; Other: Usual Care

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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: 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: 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; Usual care treatment for dizziness presenting in the emergency department (ED). Usual care consists of any ED testing or treatment not involving an ED physical therapist in accordance with the treating physician's usual and customary practice. This could include diagnostic imaging, patient education and resources, and administration and/or prescribing of medications.	Other: Usual Care; Standard-of-care treatment for dizziness presenting in the emergency department

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Longitudinal participant surveys (effectiveness): missing data rate for the Dizziness Handicap Inventory	Rate of missing data for assessments administered between baseline and 12 months. Variable type: binary / proportion.	12 months
Longitudinal participant surveys (effectiveness): screening-to-enrollment ratio	Number of participants who enter screening compared to the number of participants who enroll in the study. Variable type: binary / proportion.	Baseline
Longitudinal participant surveys (effectiveness): participant retention rate defined as completion of at least one follow-up survey.	Ratio of participants enrolled to the number who complete at least one follow-up survey.	12 months
Electronic Health Record (EHR) extraction (implementation): adoption of Emergency Department (ED) physical therapy	Adoption is defined as the number of potentially eligible dizziness ED visits have a documented order for a physical therapy evaluation. Cross-sectional at the level of site/Emergency Department during the trial. Variable type: Proportion.	Baseline
Electronic Health Record (EHR) extraction (implementation): fidelity of Emergency Department (ED) physical therapy	Fidelity is defined as the number of dizziness ED visits that have a structured research note documenting use of the protocol.
