Hi, I’m Tim Spencer and welcome to my evidence blog. As an experienced Vascular Access Specialist and Critical Care Nurse for over 35 years, my clinical background and qualifications began in Coronary and Intensive Care Nursing, Advanced Clinical Nutrition, Vascular Access and Ultrasound. Previously, I was the Clinical Nurse Consultant of the Central Venous Access and Parenteral Nutrition Service which I established in 1996, and successfully lead for over 21 years at the Liverpool Hospital, a ~1000-bed academic institution in Southwest Sydney, Australia. Today, this service is a world-class example of a full provision vascular access service, entirely managed and run by nurses.
Today, as the Director/CEO of Global Vascular Access, LLC, my focus now is to improve ultrasound-guided vascular access procedures for clinicians globally, and provide all clinicians with a greater understanding of vessel health strategies and improved patient safety to prevent ongoing vascular access-related complications and patient harm.
Global Vascular Access, LLC is a specialized, clinician-focused organization, offering practice management, education, content development, research, and consultancy services to clinicians and healthcare facilities involved in vascular access procedures, ultrasound applications, and related knowledge-based education. Established to collaborate with high-quality healthcare groups and industry leaders, the organization serves as a strategic partner, providing evidence-based resources and expertise to enhance practice support infrastructure. By doing so, Global Vascular Access, LLC positions its partners for sustained growth and success, ultimately improving clinician performance, facility outcomes, and patient satisfaction.
I have been instrumental in helping advance the scope of clinicians knowledge and skills in vascular access issues, and have contributed to clinical research and evidence-based literature in promoting patient safety, improved clinical practices and patient outcomes in Vascular Access. I also provide mentorship for new writers and have helped a number of clinicians to academic publications, something I am very proud of.
I had the honor of being the 2019 recipient of the Suzanne LaVere Herbst Award for Excellence in Vascular Access, the highest distinction bestowed by AVA, in recognition of my contributions to the art and science of vascular access.
As an early pioneer in the advanced non-physician vascular access specialist role, I am deeply engaged in clinical education, healthcare simulation, research, and the advancement of evidence-based practices in ultrasound-guided vascular access procedures. With a strong commitment to high-quality, evidence-based literature and education, my focus is on promoting a comprehensive approach and best practices in vascular access, emphasizing the enhancement of clinician skill sets and the reduction of patient harm.
I am currently enrolled at a Doctoral (PhD) student focusing on preventing arterial catheter failure in adults at the University of Wollongong, Australia.
