Dr. Phillip Hayes

Dr. Phillip Walton Hayes, 81 of Dickson, TN passed away peacefully on March 28th, 2024, at Alive Hospice in Nashville, TN.

Phil was born on February 18, 1943, to Mitchell and Virginia Hayes and was a lifelong resident of Dickson, TN.

From an early age, Phil loved the outdoors and was one of the first Eagle Scout recipients in the Highland Rim District. During his High School years, he was an accomplished athlete and excelled in football and basketball at Dickson High School earning him an All-Midstate selection as quarterback. Not only did Phil excel in athletics but in leadership and academics as well, he was president of his class all four years of high school.

Phil went on to attend Vanderbilt University as an undergrad and was a member of Sigma Chi fraternity, he then went on to medical school at the University of Tennessee Memphis and completed his residency at Vanderbilt University. Upon completion of his residency, Phil came back to Dickson to start his practice in Internal Medicine and Gastroenterology. At this time, he was the first Internist in Dickson and loved helping his patients and serving his community.

Due to health reasons, Phil decided to leave his practice and later started CHASE, LLC which remains in operation today, 33 years after its inception. Phil poured his heart and soul into CHASE, making it a very successful business. He not only enjoyed the business aspect of CHASE he cherished the long-time friends and relationships that developed during his time there.

Phil was an avid duck hunter and a long-standing member of the Davy Crocket hunting club. He had previous involvement with the Tennessee Conservation League and the Tennessee Wildlife Resource Agency (Commissioner). In his later years, Phil very much enjoyed watching and playing the stock market, reading and spending time with his friends during duck season. Phil also loved his family and found special joy with his granddaughters.

If you ever got to spend time with Phil Hayes, you know one of his God given talents was telling stories. He was by far the best storyteller we will ever know, and we will forever miss his story telling hours sitting on the porch watching the Buffalo River.

It is hard to summarize the life of Phil as it is one that was full of not only accomplishments but adventures.


Oral Fluid Testing Part 1

Over the next few months, we will be sharing more information about Oral Fluid testing. Now is the time to start making decisions about how you will incorporate Oral Fluid testing into your DOT drug testing program.  Your choices will need to be documented, included in your testing policies and shared with all clinics and collection companies that you utilize for testing.

The United States Department of Transportation (DOT) has approved oral fluid drug testing for DOT-regulated employers. Oral fluid testing will not begin until two laboratories are certified by the United States Department of Health and Human Services (HHS). This is still not available at this time.

Pros of Oral Fluid Testing

  • Cheating on oral fluid testing is more difficult
  • Can eliminate the three-hour shy bladder wait
  • There is a shorter window of detection than urine testing, so it’s beneficial for reasonable suspicion testing and post-accident testing
  • Eliminates direct observation dilemma

Cons of Oral Fluid Testing

  • Different detection rates from urine tests may hold donors to differing standards
  • Does not show historical drug use, so may miss positives that a urine test would catch
  • Untested in a largescale environment, like a job site, to know the true logistics of testing with this method

Non-DOT Programs

Now is a good time to reevaluate your employees in NonDOT positions and put a drug testing program in place. Let CHASE help you get started.
