Brief summary
Comparison of respiratory outcomes in patients receiving telemedicine-guided remote pulmonary function testing (rPFT) with or without the additional support of nurse coaching. This is a randomized controlled study which assesses the effects rPFT and coaching on respiratory outcomes and quality of life.
Detailed description
This is a two-arm, randomized study to determine 1) whether weekly monitoring of respiratory function can lead to timelier initiation of NIV and 2) whether structured nurse coaching leads to improved self-efficacy for managing disease and better maintenance of respiratory health. For enrollees in both arms, standard FVC and MIP measurements obtained approximately every three months by the respiratory therapist during ALS Clinic are supplemented with self-administered rPFTs performed weekly. Enrollees in the rPFT+NRHC (nurse respiratory health coaching) arm will additionally receive monthly coaching with the study nurse via telehealth. Outcomes include measures of quality of life and self-efficacy for managing disease.
Interventions
Telemedicine delivery of pulmonary function testing in ALS, including Forced Vital Capacity (FVC) and Maximal Inspiratory Pressure (MIP)
Standard clinical delivery of pulmonary function testing in ALS, including Forced Vital Capacity (FVC) and Maximal Inspiratory Pressure (MIP)
Nurse Respiratory Health Coaching - The NRHC intervention follows the teamlet model described by Bennett et al. \[Bennett2010\], made up of the research coordinator who performs respiratory testing, and the nurse practitioner who coaches using the GROW (goals, realities, options, wrap-up) model.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Self-efficacy for Managing Symptoms | 1 year | The self-efficacy assessment contains questions from the PROMIS item bank on Self-Efficacy for Managing Symptoms (9 items). Cumulative T-scores from each test bank were reported at months 0, 3, 6, 9, and 12, with a mean score of 50±10, higher numbers indicating greater self-efficacy. The reported value is the slope of regression of self-efficacy on time, in T-score points per month. |
| Date of Identification of Noninvasive Ventilation (NIV) Need From rPFT Monitoring | 1 year | NIV is typically prescribed when an individual demonstrates signs of respiratory failure. In this study, forced vital capacity (FVC) of 50% or less of the predicted value serves as a surrogate for respiratory failure and constitutes identification of NIV need. First date of remote measurement of FVC 50% or less of the predicted value is reported here. |
| Date of Identification of NIV Need From Standard PFT Monitoring | From date of enrollment until first identification of non-invasive ventilation need, assessed up to 1.5 years | NIV is typically prescribed when an individual demonstrates signs of respiratory failure. In this study, forced vital capacity (FVC) of 50% or less of the predicted value serves as a surrogate for respiratory failure and constitutes identification of NIV need. First date of standard, in-clinic measurement of FVC 50% or less of the predicted value is reported here. |
| Self-efficacy for Managing Medications and Treatments | 1 year | The self-efficacy assessment contains questions from the Patient-Reported Outcomes Measurement Information System (PROMIS) item banks on Self-Efficacy for Managing Medications and Treatments (4 items). Cumulative T-scores from each test bank were reported at months 0, 3, 6, 9, and 12, with a mean score of 50±10, higher numbers indicating greater self-efficacy. The reported value is the slope of regression of self-efficacy on time, in T-score points per month. |
| Self-efficacy for Managing Social Interactions | 1 year | The self-efficacy assessment contains questions from the PROMIS item bank on Self-Efficacy for Managing Social Interactions (5 items). Cumulative T-scores from each test bank were reported at months 0, 3, 6, 9, and 12, with a mean score of 50±10, higher numbers indicating greater self-efficacy. The reported value is the slope of regression of self-efficacy on time, in T-score points per month. |

Outcome results
Date of Identification of NIV Need From Standard PFT Monitoring
NIV is typically prescribed when an individual demonstrates signs of respiratory failure. In this study, forced vital capacity (FVC) of 50% or less of the predicted value serves as a surrogate for respiratory failure and constitutes identification of NIV need. First date of standard, in-clinic measurement of FVC 50% or less of the predicted value is reported here.
Time frame: From date of enrollment until first identification of non-invasive ventilation need, assessed up to 1.5 years
Population: Subset of patients include those who have a date of identification of NIV need from both remote PFT monitoring and standard monitoring.
