Social Incentives to Increase Mobility

Study Overview
=================
Brief Summary
-----------------
This study aims to assess the effectiveness of a social incentive-based gamification intervention to increase physical activity in the 3 months after hospital discharge.

Detailed Description
-----------------
This study aims to assess the effectiveness of a social incentive-based gamification intervention to increase physical activity in the 3 months after hospital discharge. To do this, the investigators will conduct a two-arm randomized, controlled trial during the 3-months after hospital discharge comparing a control group that uses a wearable device to track physical activity to an intervention group that uses the same wearable devices and receives a supportive social incentive-based gamification intervention to adhere to a step goal program. Patients will be enrolled during hospitalization from medicine and oncology floors into three phases. In phase 1 (hospitalization), patients inpatient step counts will be monitored. In phase 2 (week 1 post-discharge), patients will have a baseline step count estimated. In phase 3 (weeks 2-13 post-discharge), patients will be randomly assigned to the control or intervention group. Patients will be considered enrolled in the trial if they complete the run-in periods (phases 1 and 2) and then are randomized into phase 3. The enrollment phase will be part of another randomized trial which evaluates the impact of three recruitment strategies on patient enrollment. This trial will be completed and unmasked to patients before they begin the phase 1 of our study. The investigators will also explore patients' physical activity while in the hospital and if that differs across floors that have or have not deployed a nursing mobility protocol. Changes in patient functional decline and 30-day hospital readmission will also be explored.

Design Details

Primary Purpose: Health Services Research
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| No Intervention: Control<br>Participants' daily step counts will be for weeks 2-13 after hospital discharge. Participants will be asked to complete surveys at 5, 9 and 13 weeks post-discharge. | |
| Experimental: Intervention<br>Participants' daily step counts will be monitored for weeks 2-13 after hospital discharge. Participants will have a weekly step goal that increases from baseline by 10% each week of the intervention (12 weeks). Participants will engage in a social incentive-based gamification based on points and levels that leverages loss aversion, which has been demonstrated to motivate behavior change more effectively with losses than gains. Participants will receive daily feedback for the step counts and weekly feedback for levels. Participants will be asked to identify a support partner, who will receive weekly reports with the the participant's points and levels balance. | Behavioral: Social Incentive<br>* Participants in the intervention arm will receive social incentives as part of the intervention.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in mean daily step count from the baseline period to the intervention period, using a wearable pedometer (Nokia Steel) to measure step count. | The primary outcome variable is the change in mean daily step count from the baseline period (week 1 post-discharge) to the intervention period (weeks 2-13 post-discharge). This will be measured using the Nokia Steel wearable device. . | 13 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 30-day hospital readmission post-discharge, using the state's hospital database | A secondary outcome variable is 30-day hospital readmission post-discharge, which will be obtained from the state-based registry. | 13 weeks | 
| Functional decline from admission to 3 months post-discharge, measured using validated survey assessments. | A secondary outcome variable is functional decline from admission to 3 months post-discharge, which will be obtained from information collected through validated survey assessments. | 13 weeks |
