Brief Summary

Aging of the population is dramatically increasing the number of hospitalized patients, with the consequent challenges of limited medical personnel and resources in hospitals. Wireless technologies that create highly connected healthcare environments are developed to help hospitals address these issues, once these technologies are perfectly integrated in the hospital environment with respect to IT infrastructure for big data storage. Such devices have proven remarkable efficiencies in monitoring patients with high patient safety, data accuracy and security, which are essential to provide high quality patient care, reduce health-related costs and optimize the management of high numbers of patients. Cough is the most common condition that results in a visit to the physician. Often coughs are benign, but sometimes can be the sign of exacerbations of a chronic respiratory disease. Exacerbations are defined in the Global Initiative for Chronic Obstructive Lung Disease (GOLD) document "as an acute event characterised by a worsening of the patient's respiratory symptoms that is beyond normal day-to-day variations and leads to a change in medication". It is assumed that, if coughs were remotely monitored, hospitals might be unburdened, patients would be empowered to self-manage their health, and that prevention of serious respiratory diseases might be facilitated, thus improving health outcomes. Unfortunately, remote monitoring for cough that rely on self-reporting is impractical, as patients do not record data very reliably. On the contrary, a microphone on the bedside table connected to a medical data analysis platform might monitor patients' cough exacerbations at night and alert the medical staff immediately.

Outcome Measures

Primary Outcomes (1)

• Measurement of the clinical performance and accuracy of the microphone and of the analysis platform to detect coughs

  The microphone signal is recorded by a micro-computer and treated by the algorithm of the analysis platform developped by the company VNV. The aim of this algorithm is to discriminate events of cough in the signal. To measure the accuracy of the algorithm, we will compare the results obtained by the analysis plateform with a polygraph which is the classical way to measure night cough. The microphone of the polygraph placed on the patient chest will control if the events are due to patients coughs or patient movements. The 2 devices (microphone and polygraph) will be recording patients during 2 consecutive nights. Unit of measurement will be the number of cough events.

  2 nights

Secondary Outcomes (2)

• Patients' acceptance on the connected microphone

  2 nights

• Medical staff's satisfaction on both the microphone and the medical analysis platform (usability, data usage)

  5 days
