2 Copyright © 2006 by Mosby, Inc. Slide 2 Chapter 9 The Therapist-Driven Protocol Program and the Role of the Respiratory Care Practitioner The Therapist-Driven Protocol Program and the Role of the Respiratory Care Practitioner

3 Copyright © 2006 by Mosby, Inc. Slide 3 Therapist-Driven Protocols (TDPs) Are an Integral Part of Respiratory Care Health Services

4 Copyright © 2006 by Mosby, Inc. Slide 4 The Purpose of TDPs  Deliver individualized diagnostic and therapeutic respiratory to patients  Assist the physician with evaluating patients’ respiratory care needs and to optimize the allocation of respiratory care services

5 Copyright © 2006 by Mosby, Inc. Slide 5 The Purpose of TDPs  Determine the indications for respiratory therapy and the appropriate modalities for providing quality, cost-effective care that improves patient outcomes and decreases length of stay  Empower respiratory care practitioners to allocate care using sign- and symptom-based algorithms for respiratory treatment

6 Copyright © 2006 by Mosby, Inc. Slide 6 Respiratory TDPs Give practitioner authority to:  Gather clinical information related to the patient’s respiratory status  Make an assessment of the clinical data collected  Start, increase, decrease, or discontinue certain respiratory therapies on a moment- to-moment basis

7 Copyright © 2006 by Mosby, Inc. Slide 7 The Innate Beauty of Respiratory TDPs Is That: 1. The physician is always in the “information loop” regarding patient care 2. Therapy can be quickly modified in response to the specific and immediate needs of the patient

8 Copyright © 2006 by Mosby, Inc. Slide 8 Clinical Research Verifies These Facts Respiratory TDPs 1. Significantly improve respiratory therapy outcomes, and 2. Appreciably lower therapy costs
