Brief Summary

This study aims to adapt an outpatient mobile app-based contingency management intervention to the hospital setting to understand how we can use contingency management to improve health outcomes in hospitalized patients with stimulant use disorders.

Detailed Description

Contingency management (CM), an evidence-based strategy that utilizes a reward-based system as positive reinforcement, has been most robustly studied in the outpatient setting, but also has the potential to improve hospital care for patients with stimulant use disorder. The hospital is a challenging environment for people who use drugs. Conflicts with staff often result from in-hospital substance use, prolonged time off the unit, and missing medications, leading to negative health outcomes and re-admissions. By relying on positive rewards to encourage positive health behaviors, CM has the potential to improve staff-patient relationships, healthcare engagement, and reduce substance use in the hospital. Stimulant use disorder is especially difficult to address in the hospital due to a lack of medications that can support cravings and withdrawal symptoms. However, little is known about CM implementation in hospitals and the hospital setting may introduce unique challenges.

The objective of this study is to adapt an outpatient mobile app-based CM intervention to the hospital setting to understand the feasibility and acceptability of a hospital-based CM intervention to improve health outcomes in hospitalized patients with substance use disorders. We'll achieve this objective through following specific aims: Aim 1: Identify adaptations needed to implement an evidence-based outpatient mobile-app based CM intervention to the hospital setting for hospitalized patients with substance use disorders. Aim 2: Determine the feasibility, including facilitators and barriers, of implementing a mobile app-based CM intervention in the hospital setting. Aim 3: Assess the acceptability of a mobile app-based hospital-based CM intervention to patients and staff.

Arm && Interventions

Group	Intervention	Description
Mobile app-based contingency management	Mobile-app based contingency management	All participants will be enrolled into an 8-week mobile app-based contingency management intervention starting during a prolonged hospitalization.

Primary Outcome Measures

Name	Time	Method
Intervention acceptability and feasibility	Week 0-8	Evaluated using semi-structured qualitative interviews with participants and staff

Secondary Outcome Measures

Name	Time	Method
Participant drug test results	Week 0-8	Participants can complete twice weekly drug testing as part of the contingency management intervention. We will measure the number of positive and negative drug tests as an objective measure of substance use.
Participant engagement in the contingency management intervention	Week 0-8	Participation in the contingency management intervention will be tracked. This includes number of counseling appointments attended and number of self-reflection activities attended. This is an implementation outcome where we measure how often participants are engaging in this intervention.
Brief Addiction Monitor (BAM)	Week 0-8	The Brief Addiction Monitor (BAM) is a 17-item, multidimensional, progress-monitoring instrument for patients with a substance use disorder. The BAM includes items that assess risk factors for substance use, protective factors that support recovery, and drug and alcohol use. This instrument will be used to monitor the progress of the participants substance use disorder. Each functional domain of the survey (use, risk, protective) has an associated composite score which serves as a marker of clinical status. For Use (Scores 0 to 12), higher scores mean more substance use. For Risk (scores 0 to 24), higher sores mean more risk. For Protective (scores 0 to 24), higher scores mean more protection.
