Telemonitoring of Treatment Effects in Connective Tissue Disease-associated Interstitial Lung Disease (TEL-CTD-ILD)

Medical University of Lodz60 enrolled

Overview

1. Impact of telemonitoring on quality of life (QoL) of patients with CTD-ILD 2. Evaluation of health status of patients with connective tissue disease-associated interstitial lung disease (CTD-ILD) using telemonitoring and standard care. 3. Assessment of treatment response patterns (full remission, partial remission, progression, no response) and evaluation of clinical prognostic factors (risk factors for poor response in patients with CTD-ILD. 4. Evaluation of cost-effectiveness of telemonitoring solutions in patients with CTD-ILD. 5. Evaluation of telemedicine as a tool for assessing the safety of therapy

Interstitial lung disease (ILD) is one of the most serious pulmonary complications related to connective tissue diseases (CTDs), resulting in substantial morbidity and mortality. Interstitial lung disease is a common manifestation of different connective tissue diseases, such as scleroderma, rheumatoid arthritis (RA), Sjögren's syndrome, systemic lupus, dermatomyositis and others. Radiological and histopathological patterns are most often nonspecific interstitial pneumonia (NSIP), organizing pneumonia (OP), usual interstitial pneumonia (UIP) and lymphocytic interstitial pneumonia (LIP). Current standard of care in progressive CTD associated ILD is low to medium dose of corticosteroids, frequently combined with immunosuppressive medication, depending on disease severity and local standards. However, based on clinical and radiological features, it is difficult to predict what will be the response to the treatment. Effectiveness of the treatment is assessed by functional tests and chest high resolution computed tomography (HRCT), performed usually after 3 months of therapy. Project objective is to assess the possible benefits of using telemonitoring of functional and vital signs, symptoms and quality of life of patients with CTD-ILD in response to treatment. In the trial patients diagnosed with CTD-ILD will be randomized to intervention group (telemonitoring) and the control group (traditional assessment). Patients from the study after initial training will perform daily spirometry (FVC), transdermal pulse oximetry, pulse and blood pressure measurements, activity measurement (accelerometry), and assessment of severity of cough and dyspnea. The additional questionnaires will also be used to assess the tolerability of treatment, quality of life and the occurrence of side effects. Telemonitoring will start 10 to 14 days before the start of treatment and will be carried out for 3 months of therapy. All patients (study and control group) will receive treatment in accordance with current treatment standards. During the 3-month observation period, visits to the center will take place at monthly intervals. In the case of treatment intolerance or deterioration of monitored parameters, patients will be evaluated at additional time points. All patients after the end of the 3-month follow-up will remain under the care of the Pulmonology Clinic and will be examined during regular visits every 3 months until the end of the 12-month follow-up period.

Outcomes

Primary Outcomes

Change from baseline health-related quality of life using EQ-5D-5L questionnaire at 3 months

The EuroQoL Group 5-Dimension 5-Level Self Report Questionnaire (EQ-5D-5L) questionnaire will be used for the assessment of quality of life. The EQ-5D-5L essentially consists of 2 pages - the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS). The EQ-5D-5L is especially suited to cost effectiveness analyses.

Time frame: at baseline, after 3 months

Change from baseline health-related quality of life using St. George's Respiratory Questionnaire at 3 months

St. George's Respiratory Questionnaire (SGRQ) will be used to assess health related quality-of-life. The SGRQ is a 50-item questionnaire developed to measure health status (quality of life) in patients with diseases of airways obstruction. SGRQ is survey with scores ranging from 0 to 100 and with higher scores indicating worse quality of life.

Time frame: at baseline, after 3 months

Secondary Outcomes

Costs of health service utilization in Polish zloty

Mean costs in telemonitoring and control group will be estimated. Healthcare utilization will be assessed through the number of emergency department, hospital or outpatient clinic visits, medications and adverse events treatments. Resource use categories will be monetarily valued using unit cost and multiplied with the collected amount of resource use. Mean costs in Polish zloty per group will be calculated.

Time frame: after 3 months, after 6 months

Assessment of Dyspnea using Modified Medical Research Council (mMRC)

The Modified Medical Research Council Dyspnea (mMRC) scale will be used to determine functional impairment due to dyspnea. It is a five-level rating scale consisting of just five items containing statements about the impact of dyspnea on the patients' daily activities performance. Higher scores indicate a greater impact of dyspnea on the patients' daily activities performance.

Time frame: at baseline, after 3 months

Assessment of fatigue using Fatigue Assessment Scale (FAS)

Fatigue Assessment Scale (FAS) will be used for assessment of fatigue status. The total score ranges from 10 to 50. A total FAS score \< 22 indicates no fatigue, a score ≥ 22 indicates fatigue.

Time frame: at baseline, after 3 months

Assessment of patients' adherence to recommended medications using the Adherence Scale in Chronic Diseases (ASCD)

The Adherence Scale in Chronic Diseases is a self-reported questionnaire with 8 items and with proposed 5 sets of answers. The total score in the Adherence Scale in Chronic Diseases ranges from 0 to 32 points. Three levels of adherence were considered (low: scores of 0 to 20; medium 21 to 25; high \> 26).

Time frame: at baseline, after 3 months

Change from baseline anxiety and depression symptoms as measured by HADS (Hospital Anxiety and Depression Scale)

The Hospital Depression and Anxiety Index (HADS) is a 14-item survey with scores ranging from 0 to 21 and with higher scores indicating greater depression and anxiety.

Time frame: at baseline, after 3 months

Change from baseline depression as measured by PHQ-9

The Patient Health Questionnaire (PHQ-9) is a 10-item survey with scores ranging from 1 to 27 and with higher scores indicating greater levels of depression.

Time frame: at baseline, after 3 months

For the telemonitoring arm, oxygen saturation (SpO2) expressed in percent

Oxygen saturation level (SpO2) will be measured by transdermal Pulse Oximeter.
