Principal Investigator left the University of Louisville.

This is a two-step observational cohort study evaluating the impact of adding PikoLogic® to the current disease management COPD discharge protocol subsequent to an admission for COPD exacerbation.

Candidate subjects participating in the cohort study will receive training by the clinical research associate (CRA) on the use of PikoLogic® for home disease management prior to discharge from the hospital. The CRA will also confirm COPD discharge education was completed by a discharge coordinator and the patient understood the instructions. The CRA will review "seek medical care if:" and "seek immediate medical care if:" instructions at discharge. The discharge CRA will also evaluate subjects for their ability to use the PikoLogic® correctly and will score the patient using an objective and subjective measurement tool. A modified Discharge Knowledge Assessment Tool© will be utilized.1 Objective measurements will include training time and patient compliance with PikoLogic® prior to discharge. Subjective data scores and objective measurements will be utilized for program implementation evaluation.
