Delirium and Neuropsychological Recovery Among Emergency General Surgery Survivors

April 8, 2026 updated by: University of Wisconsin, Madison

Delirium and Neuropsychological Recovery Among Emergency General Surgery Survivors (DANE)

This study will evaluate the usefulness of the Urgent and Emergency Surgery (UES) Delirium Recovery Model. It is hypothesized that the cognitive, physical and psychological recovery of older UES delirium survivors will be improved through the use of the DANE Recovery Model. Participants can expect to be on the study for 18 months.

Detailed Description

This is a multi-site, two-arm, single-blinded randomized controlled clinical trial to evaluate the efficacy of the DANE Recovery Model to improve the cognitive, physical and psychological recovery of older UES delirium survivors. At or near the time of discharge, enrolled participants will be randomized to receive the DANE Recovery Model or usual care. The hypothesis is that, after 18 months, older UES delirium survivors who are randomized to the DANE Recovery Model will experience more favorable cognitive, physical and psychological recovery in comparison to those randomized to usual care.

How is the study designed?

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Other: Usual Care
Participants will receive the usual rehabilitation and post-operative care.
Physical, cognitive, and psychological assessments
Virtual visits with care coordinator to carry out an individualized recovery plan
Experimental: DANE Recovery Model
The delivery of the model will occur in five phases that correspond to the known stages of recovery after surgery. During the acute stage (0 - 1 month after surgery), participants will undergo the initial case review and two initial virtual visits, and the development of the recovery care plan. During the recovery (2 - 6 months after surgery) and maintenance (7-12 months after surgery) stages, the participants will undergo the interaction phase of the DANE Recovery Model.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in overall cognitive recovery
Time Frame: Baseline, 6 months, 12 months, and 18 months
Change in score on the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) cognitive screening assessment. The measure consists of 12 subtests that contribute to a total score and Index scores across five domains: Immediate Memory, Visuospatial-Constructional, Language, Attention, and Delayed Memory. Index scores are converted to age-based standard scores (Mean = 100, Standard Deviation = 15)
Baseline, 6 months, 12 months, and 18 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Short Physical Performance Battery (SPPB)
Time Frame: Baseline, 6 months, 12 months, and 18 months
Change in overall physical recovery will be assessed using Short Physical Performance Battery (SPPB). SPPB is a group of measures that combines the results of the gait speed, chair stand and balance tests, and yields a performance score of 0-12; 0-4 poor, 5-7 intermediate, 8-12 good.
Baseline, 6 months, 12 months, and 18 months
Change in overall physical recovery
Time Frame: Baseline, 6 months, 12 months, and 18 months
Change in overall physical recovery will be assessed using 36-Item Short Form Survey (SF-36). SF-36 scale has eight components (physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, and mental health).
Baseline, 6 months, 12 months, and 18 months
Patient Health Questionnaire-9 (PHQ-9)
Time Frame: Baseline, 6 months, 12 months, and 18 months
Change in overall psychological recovery will be assessed using Patient Health Questionnaire-9 (PHQ-9). The PHQ-9 is a nine-item depression scale with a total score from 0 to 27, with higher scores indicating greater depression.
Baseline, 6 months, 12 months, and 18 months
General Anxiety Disorder-7 (GAD-7) .
Time Frame: Baseline, 6 months, 12 months, and 18 months
Change in overall psychological recovery will be assessed using General Anxiety Disorder-7 (GAD-7) to determine the impact of the intervention on participant's mood and anxiety. The GAD-7 is a seven-item anxiety scale with a total score from 0 to 27, with higher scores indicating greater anxiety.
Baseline, 6 months, 12 months, and 18 months
