The goal of Montgomery County Hospital District’s Department of Clinical Services is to provide a consistent and superior system of emergency and non-emergency services to our community and provide support for our employees through leadership and professional management.  This includes protocol development, oversight of the electronic Patient Care Record (PCR), quality improvement process, professional development, continuing education, provider credentialing, community education, and integration of the care MCHD provides with the healthcare community

The Clinical team employs the following tools to improve MCHD’s success:

  • Review and analysis of all reports related to strokes, cardiac events, and trauma
  • Regular attendance at local emergency department meetings to foster clear lines of communication and quality improvement
  • Regular case reviews with emergency department personnel and the paramedics on those cases
  • Procedural review, changes and/or training as called for by the case reviews
  • Studies on the implementation and effectiveness of best practices
  • Published research papers

 

A critical role of the department is ensuring MCHD’s paramedics are trained and best positioned to utilize their knowledge, abilities, and talents in the field.  MCHD creates an environment where our paramedics continuously develop their skills as a provider while growing within the agency and are trusted with more responsibility.  The following are the different levels of credentialing utilized by MCHD.  In order to maintain the current level of authorization, the paramedic must successfully pass a re-credentialing exam every other year.

  • PI – Attendant: This is an emergency medical provider who has passed credentialing exams and holds a TDSHS EMT-Intermediate or EMT-Paramedic certification or license.
  • PII – In Charge: This is a paramedic who has shown clinical proficiency through multiple written and scenario evaluations. They have limited clinical authority and consults with higher-authorized provider prior to performing certain skills.
  • PIII – In Charge: An In Charge who has demonstrated enhanced clinical proficiency beyond that of a PII. This paramedic has an expanded level of clinical authority and is no longer required to consult with a higher-authorized provider prior to performing certain skills.
  • PIV – Supervisor: The highest level of authorization for MCHD is a PIV. This employee has shown excellent operational and clinical proficiency. They are authorized to provide medical direction through consults to paramedics at lower levels of authorization.

MCHD Department of Clinical Services shares our best practices and lessons learned and often publishes our findings through professional journals and magazines. Below are a few of our most recent publications:

 

 

 

Dr. Dickson is a native Texan and graduated from the University of Texas San Antonio medical school in 1997. He did emergency medicine post – graduate training at Indiana University and has worked as a practicing emergency physician and educator in Texas and NZ. He is board certified in emergency medicine, EMS medicine and holds fellowship in both the American and Australasian Colleges of Emergency Medicine. His academic interests include   acute neurologic emergencies, EMS and systems of care in time sensitive emergencies. He has authored multiple articles on these topics and has lectured regionally, nationally and internationally. In his spare time he enjoys cycling, travel and swimming.

 

 

 

 

 

Casey Patrick grew up in Williamsburg, KY and graduated from The University of the Cumberlands in 2000.  Following his undergraduate studies, Patrick received his MD from The University of Kentucky College of Medicine in 2004. In 2007, he completed residency training in Emergency Medicine at Indiana University.  Since residency he has practiced EM in both Indiana and Texas. Currently, Dr. Patrick is Assistant Medical Director for the Montgomery County Hospital District EMS service and works in multiple community emergency departments in the Greater Houston area.  His EMS educational  focus is on innovative paramedic teaching via the MCHD Paramedic Podcast  Dr. Patrick’s prehospital clinical research involves using bolus intravenous nitroglycerin for acute pulmonary edema and implementation of lung protective ventilation strategies for EMS patients. Casey and his wife, Alyssa, work and live in Conroe, TX and Spokane, WA. Together they have five children: Mia, Ainsley, Brock, Dean and Will.
