- Brief Summary
Early detection of pulmonary exacerbations (PEx) in Cystic Fibrosis (CF) patients is important to quickly trigger treatment and reduce respiratory damage. The investigators hypothesize that using home-based connected devices (CDs) in educated patients applying Cumulative sum charts (CUSUM) to monitor physiological parameters (PP) and patients' perception reported (PRP), will allow early detection of PEx.
Objective: to study clinical validity of using CDs and evaluate adherence and satisfaction in CF patients and teams
Design: 3 phase multicenter study in 36 CF patients aged \>=12 years. Phase 1, patients are equipped during 3 months with CDs. PP and PRP to estimate CUSUM parameters are collected. In phase 2, patient's personalized educational plan to manage alerts is built. In phase 3, PP and PRP are collected during 12 months. Clinical validity, change in patients clinical data, quality of Life/Anxiety-Depression/Satisfaction, patients and teams' acceptance and adherence are assessed.
- Detailed Description
BACKGROUND
Pulmonary exacerbations (PEx) are the major cause of lung function decline in Cystic Fibrosis (CF) patients leading to respiratory failure. Identifying warning signs of PEx is a priority to trigger early treatment and reduce respiratory damage. Some authors tried to define scores based on symptoms to standardize treatment. However, lack of consensus led the Euro-Care-CF-Working-Group to recommend the use of medical antibiotic treatment decision (or treatment modification) associated with PEx-like symptoms as best definition of PEx for clinical trials.
A DELPHI study identified 10 signs frequently perceived by patients and 10 most often cited indicators by caregivers. Two studies have shown that a combination of physiological parameters (PP) and patient reported perceptions (PRP) such as weight loss, decreased spirometry , increased cough or increased sputum production reported daily, help diagnose PEx episodes and trigger early treatment. Clinical observations show that changes in PP and PRP related to PEx differ according to age and degree of lung function impairment. Currently, patients with CF do not routinely monitor their lung function at home, nor do they objectively track PP or PRP. Consequently, CF PEx can be diagnosed late when symptoms progress, in which they seek medical care. Thus, development of an effective approach that helps to monitor daily indicators of PEx to early identification and treatment is important.
* Home monitoring of PEx symptoms Several studies have been conducted with daily monitoring of PEx symptoms. Most of these studies monitored one or two respiratory parameters with data transmission to the medical staff who decide what course of action to take. In addition, these studies used for each parameter the same alert limit for all patients, as it is known that patients with CF have different thresholds of these indicators,some may present more frequently than others.
* CUSUM to monitor indicators of pulmonary exacerbation The use of statistical process control (SPC) shows promise for monitoring indicators of CF PEx and rapidly detecting unwanted changes in these indicators. SPC uses rigorous time-series analysis methods, with results reported as a graph of changes in indicators over time\[9\]. Moreover, SPC can help to determine whether these changes are real (related to a causative factor) or merely a manifestation of natural variability. Among SPC, cumulative sum (CUSUM) chart has been found effective for measuring and monitoring healthcare outcome. It detects changes rapidly, and can identify small shifts. Connected devices software programming integrating CUSUM alert limits can help to determine whether the changes in PP and PRT are due to real PEx episode.
STUDY HYPOTHESIS The investigators hypothesize that using home-based CDs applying CUSUM with patient's personalized alert limits to monitor physiological data and PRP combined with patient education allows early detection of PEx. Studying alerts can help clinicians to develop a patient's personalized educational plan allowing patients better management of PEx including ability to make informed choices. This study aims to assess clinical validity of using different CDs, acceptance and adherence of patients of data collection of physiological data and PRPs, and acceptance by the clinical teams of this process of care. It will lead a larger trial aiming to evaluate efficacy of this process of care on patient's clinical outcomes.
DESIGN
Design: A 3 phase multi-center prospective longitudinal pilot study will be conducted.
- Phase 1- Baseline data collection Clinic staff will email all patients or parents (pediatric settings) to introduce the study. A qualitative interview with 10 patients who declined to participate in the study will be conducted to identify the reason of refusal.
M0: Inclusion visit: the inclusion will be proposed at a follow-up visit by the child's or adult's referring doctor. A written informed consent form will be obtained from all adults or both parents of children.
Quality of Life and Anxiety-Depression will be collected using the HADS and CFQ-R scale Each included patient will be equipped with CDs-spirometer, oxymeter, scale and watch During 3 months: Baseline data of 14 warning indicators of Pex will be collected during 3 non consecutive days a week using the CDs.
Number and time of acute PEx, FEV1, weight, respiratory symptoms and antibiotic treatments prescribed will be collected at the end of the period from the medical patient chart in the CF centre.
* Phase 2- statistical analysis and patient education Statistical analysis of the data collected in phase 1 will take place to calculate the CUSUM parameters. Alert parameters for each patient are then fixed. An educational visit will be scheduled with patients
* Phase 3- CDs use and personalized care PP and PRP will be continuously collected during 12 months using CDs. If alerts occur, patients will be informed by email or SMS, with data transmission to the medical team who will not interfere. Patients should apply the shared action plan they learned. Quality of Life and Anxiety-Depression will be collected using the HADS and CFQ-R scale. Number and time of acute PEx, FEV1, weight, respiratory symptoms and antibiotic treatments prescribed during the period will be collected at the end of the period from the medical patient chart in the CF centre.
At the end of Phase 3: Semi-structured interviews will be completed with the 30 patients/parents and 5 medical teams to explore confidence on the CDs, impact on the doctor-patient relationship, change in the workload of medical team...etc.
EXPECTED RESULTS
The investigators expect a better quality of life for patients, and that their anxiety-depression has not increased or rather decreased. For the clinical teams, the investigators aim to demonstrate that the use of CDs at home by educated patients is acceptable in their daily workload, and satisfying regarding the application of the shared action plan by the patient. Unlike other studies, patients are empowered to initiate actions when alerted by variations of the parameters. If they don't follow the action plan decided with the clinical teams, the treatment of PEx might not be earlier than if they didn't use CDs. In that case, a discussion with the clinicians may lead to the alternative process in which the alerts are used by the clinical teams to drive the actions for the patient. Interestingly, this alternative is possible because the alerts are simultaneously transmitted to the patient and to the team. The leader in the process may even change at some critical periods when the patient is in bad condition or depressed.
Qualitative analysis will provide knowledge on benefits and pitfalls to improve confidence in the use of CDS at home from the patients and the clinical teams, improve the patient-team partnership and, decrease stress and anxiety about pulmonary exacerbation treatment. This study will lead to further plan a larger trial aiming to evaluate efficacy of this process of care on patients' clinical outcomes
Scientific innovation The use of home based CD is rapidly growing and their contribution to the diagnosis of Pex in CF patients deserves to be fully evaluated. The use of CUSUM is particularly promising for monitoring indicators of CF PEx. Because CUSUM chart detects rapidly changes in these indicators and can identify small persistent shifts, it can help to trigger early treatment and reduce respiratory damages.
Furthermore, this is the first study which uses a combination of numerous CDs to evaluate several warning indicators of PEx. In addition, putting patients at the center of their health care and giving them more autonomy (empowerment) is innovative in this type of study and can improve both detection and management of their PEx episodes.
