Medication Adherence in Patients With Sarcoidosis

Study Overview
=================
Brief Summary
-----------------
The goal of the study is to look at the relationship between how individuals with Sarcoidosis take the sarcoidosis medicines and how it affects the disease, to evaluate any factors that may make individuals not want to take the medicines, and to develop and refine ways to help support individuals with Sarcoidosis especially when it comes to the medicines. The overall hypothesis is higher medication adherence will be associated with better clinical outcomes in sarcoidosis. The investigators will enroll 150 patients with biopsy proven pulmonary sarcoidosis for at least one year who are on any oral treatment regimen for at least six months into a 12-month longitudinal study.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in King's Sarcoidosis Health Questionnaire (KSQ) score | The KSQ is a 29-item validated measure of sarcoidosis health status. Scores range from 0 to 100. Higher KSQ scores are better. Lower KSQ scores are worse. | Baseline, 6 months and 12 months | 
| Change in St. George's Respiratory Questionnaire (SGRQ) score | The SGRQ is an instrument that contains 50 items in three subscales (symptoms, activity, and impact). Scores range from 100 to 0. Lower scores for the SGRQ are better and higher scores are worse. | Baseline, 6 months and 12 months | 
| Change in Forced Expiratory Volume (FEV1) as assessed by Pulmonary Function Testing | Forced Expiratory Volume (FEV1) will be collected by performing Pulmonary Function Testing using spirometry. FEV1 is the maximum amount of air that can be forcibly exhaled in one second. | Baseline, 6 months and 12 months | 
| Change in Forced Vital Capacity (FVC) as assessed by Pulmonary Function Testing | Forced Vital Capacity (FVC) will be collected by performing Pulmonary Function Testing using spirometry. FVC is the amount of air that can be forcibly exhaled from the lungs after taking the deepest breath possible. | Baseline, 6 months and 12 months | 
| Change in Diffusing Capacity of Lung for Carbon Monoxide (DLCO) as assessed by Pulmonary Function Testing | Diffusing Capacity of Lung for Carbon Monoxide (DLCO) is a measure of the efficiency of lung gas transfer. DLCO will be collected by performing Pulmonary Function Testing after performing spirometry. | Baseline, 6 months and 12 months | 
| Change in 6-minute walk distance | The distance (in meters) a participant is able to walk in 6 minutes will be assessed. | Baseline, 6 months and 12 months | 
| Change in Modified Medical Research Council Dyspnea Scale (MRC) score | MRC is a simple scale that has been validated as a method of categorizing patients in terms of their disability attributable to dyspnea. The scale has 5 items on it. Scores range from 0 to 4. Higher scores are worse and lower scores are better. | Baseline, 6 months and 12 months | 
| Change in Health Care Utilization (HCU) as assessed by the CRISP Database | Health Care Utilization (HCU) for 12 months prior to enrollment and the duration of the study for a total of 24 months will be obtained through the Chesapeake Regional Information System for our Patients (CRISP) database. With consent, researchers are able to receive real-time notifications whenever a participant receives care at any of the hospitals or long-term care facilities. Data available on participants includes records from hospitalizations such as discharge summaries, diagnosis, imaging, and laboratory values. Hospitalization and emergency department (ED) utilization will be coded as a yes/no event. We will also collect self-report hospitalizations and ED visits from the participants at each study visit. | 12 months prior to enrollment and the duration of the study for a total of 24 months |
