Overview
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.
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.
Eligibility
Inclusion Criteria:
Patients- Possess a diagnosis of definite, probable, probable laboratory-supported, or possible ALS by revised El Escorial research criteria [Brooks2000].
- Be 18 years of age or older.
- Have a caregiver available to participate in the study
- Symptom onset within the last three years.
- Have a computer and home internet service sufficient for engaging in telemedicine sessions.
- Have a second device capable of downloading the spirometer application from an app store (Android- or iOS-based smartphone or tablet).
- Be 18 years of age or older, of either gender.
- Be able and willing to provide informed consent.
Exclusion Criteria:
Patients- Use of NIV or diaphragm pacer at time of obtaining informed consent.
- FVC 50% predicted or MIP > -60 cm of water.
- ALS Functional Rating Scale (ALSFRS-R) [Cedarbaum1999] score on day of screening of 2 on items for speech, swallowing, and salivation. These items are indicators of bulbar dysfunction, which limits the reliability of PFT administration.
- Cognitive impairment, as judged by the ALS clinic neurologist, that prevents participation in the study.
Caregivers: None
