Study Details

Study Description

Brief Summary

This study aims to examine the safety and efficacy of the Percussion Device in detecting a pneumothorax in patients that have undergone thoracic surgery.

Condition or Disease Intervention/Treatment Phase
  • Device: Percussion Device (PD)
  • Device: Ultrasound (US)
N/A

Detailed Description

A prospective, non-randomized clinical feasibility cohort study. The purpose of this feasibility study is to collect preliminary performance and safety information for the Percussion Device (PD). Patients satisfying the inclusion criteria will be approached for study enrolment before their surgery in clinic. Following surgery and after the patient's chest tube has been removed, evaluation of the chest using the PD and ultrasound will be performed by two independent assessors (a nurse practitioner or resident on the Thoracic Surgery Team) prior to the post-removal CXR. Details of study procedure are details in section 2.8. The PD's performance metric will be compared against CXR results, which is considered the gold standard in diagnosing a pneumothorax.

Arms and Interventions

Arm Intervention/Treatment
Experimental: PD arm

Patients undergoing assessment of the chest with the percussion device (PD).

Device: Percussion Device (PD)
A laboratory prototype of the Percussion Device (PD) has been designed and built; laboratory data collection software, signal analysis and classification algorithms have been developed. It has been designed to detect a pneumothorax.

Active Comparator: US arm

Patients undergoing assessment of the chest with the ultrasound (US).

Device: Ultrasound (US)
The SonoSite hand help portable ultrasound device.

Outcome Measures

Primary Outcome Measures

  1. Performance metrics [2 years]

    Performance metrics of the PD in detecting the presence of a pneumothorax following the removal of the last chest tube in patients that have undergone thoracic surgery compared to the CXR reported by a blinded radiologist unaware of the study.

Secondary Outcome Measures

  1. Inter-rater reliability [2 years]

    The secondary outcomes will include inter-rater reliability with the PD or ultrasound or CXR.

  2. Adverse Events [2 years]

    Any adverse event associated with the PD or ultrasound or CXR.

  3. Marginal Costs [2 years]

    Marginal costs differences between the surgeon performed PD and CXR will be based on an overall risk-benefit assessment that will take into account accuracy and costs of facilities as well as physician services.
