Effectiveness of Interventions to Teach Respiratory Inhaler Technique (E-TRaIN) (E-TRaIN)

Effectiveness of Interventions to Teach Respiratory Inhaler techNique (E-TRaIN)

The purpose of this study is to evaluate the relative effectiveness of two different ways to teach subjects while hospitalized how to use respiratory inhalers and to follow-up after discharge home from the hospital to determine durability of the education.

Teach-to-Goal (TTG) education employs instruction followed by patient "teach-back," then repeated cycles of learning and assessment until a skill is mastered. By contrast, Brief Intervention (BI) education only consists of providing the patient with verbal and written instruction.

The investigators hypothesize that hospital-based TTG compared to BI increases a patient's ability to retain instructions on respiratory inhaler technique. The investigators will test this hypothesis separately for the MDI and Diskus® devices after discharge.

Study Overview

• Status: Completed
• Conditions: Asthma; Chronic Obstructive Pulmonary Disease (COPD)
• Intervention / Treatment: Behavioral: Teach-To-Goal; Behavioral: Brief Intervention

Detailed Description

Respiratory inhalers are often used incorrectly by patients with obstructive lung disorders (including patients hospitalized with exacerbations of asthma or chronic obstructive pulmonary disease (COPD). As the mainstay of bronchodilator and anti-inflammatory therapy in patients with OLD, the implication of this difficulty with self-management is that patients are at risk for under-treatment and worse health outcomes. Several factors are thought to contribute to poor self-management skills, particularly inadequate patient education at healthcare encounters and inadequate patient health literacy. However, the most effective strategy to instruct patients about respiratory inhaler use in hospital settings is unclear, particularly in populations enriched with inadequate health literacy.

Therefore, the overall goal of this study is to evaluate the relative effectiveness of two hospital-based educational interventions: Teach-To-Goal (TTG, iterative cycles of demonstration-based education and assessment) versus Brief Intervention (BI, one-time set of verbal instructions) on the durability of instructions provided in the hospital and its effect on clinical outcomes (e.g., respiratory events and/or death), post hospital discharge. The investigators also plan to evaluate whether the relative effectiveness of TTG vs. BI varies by level of health literacy. The objectives of this proposal are to conduct a study in adults hospitalized with asthma/COPD to 1) to evaluate the relative effectiveness of hospital-based TTG versus BI on patients' ability to retain instruction about the correct use of MDI and Diskus® devices after discharge home and 2) To determine the relative effectiveness of TTG compared to BI for patients with less-than-adequate health literacy compared to those with adequate health literacy. These data will inform the development of a larger, multi-center clinical trial.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
EXPERIMENTAL: Educational Intervention A; Intervention: Teach to Goal	Behavioral: Teach-To-Goal; Participants observe a demonstration on the use of each inhaler, with corresponding verbal step-by-step instructions (demonstration, verbal instruction), then participants 'teachback" or re-demonstrate the steps; cycles are repeated are read step-by-step instructions (verbal instructions) for each respective inhaler (Metered Dose Inhaler +/- Diskus), and receive a copy of these instructions with images depicting the steps (written instructions)
EXPERIMENTAL: Educational Intervention B: Brief Intervention	Behavioral: Brief Intervention; Participants are read step-by-step instructions (verbal instructions) for each respective inhaler (Metered Dose Inhaler +/- Diskus), and receive a copy of these instructions with images depicting the steps (written instructions)

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percentage of Participants With MDI Misuse From Baseline to 30 Days Post-Discharge	To evaluate the relative effectiveness of hospital-based TTG versus BI on patients' ability to retain instruction about the correct use of MDI Devices one month after discharge home.	1 month

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Role of Health Literacy - Number of Less-Than-Adequate Health Literacy Participants With 30 Days Post Discharge Acute-Care Events	To determine the relative effectiveness of TTG compared to BI for patients with less-than-adequate health literacy using self-reported acute-care events 30 days post discharge. To measure less-than-adequate health literacy, the investigators administered the Short Test of Functional Health Literacy in Adults, a validated tool to assess whether a participant has adequate, marginal, or inadequate health literacy. Less-than-adequate included marginal and inadequate health literacy.	1 month
Number of Participants With Self-Efficacy	This is a self-reported measure of how confident a participant is on how well they use their metered dose inhaler.	1 month
Symptom Control	Symptom control will be assessed using interviewer-administered surveys. Using the Borg Dyspnea Scale, a validated Scale from 0 - 20 where 20 is maximal dyspnea, we took the difference between the the 30 day follow-up self reported shortness of breath from baseline to see if there was improvement in symptom control.	1 month
Number of Participants With Acute Care Events 30 Days Post Discharge	Exacerbation/acute care events within one month of hospital discharge	1 month
