Patient Care & Clinical Services

Our infectious disease specialists provide consult services to patients. Clinical services are provided at both inpatient and outpatient settings. 

IDS faculty physicians pursue a team approach to providing exceptional patient care, working closely with hematologists and oncologists on individual treatment plans for patients. Our researcher physicians also oversee critical quality-improvement initiatives related to infectious diseases, including the development of standard practice guidelines and other clinical care guidelines in infection control and antibiotics management.

Our Patient Services Include:

  • Partnering with hematologists and oncologists on treatment plans
  • Overseeing quality exercises related to infectious diseases
  • Developing standard practices and guidelines in infection prevention and control
  • Conducting pre-transplant evaluations
  • Managing patient follow-up visits, including antibiotics management
  • Creating long-term follow-up plans

Patient appointments are limited to current patients and require a referral from your Fred Hutch primary provider.

Our faculty work at the interface of patient care and scientific discovery.

In partnership with the patient and a multidisciplinary team, our clinicians strive to provide the highest quality care. As leaders of clinical research and trials, IDS faculty advance scientific knowledge to improve treatment and prevention of the infectious diseases that afflict our patients.

Debra Mattson Award

Debra Mattson
Debra Mattson

The Debra Mattson Award was established in honor of Debra Mattson's 30-year career in caring for thousands of patients and her role in the Infectious Disease Consult Service.  As a physician assistant, Mattson provided care with kindness and respect while having a thorough knowledge of the patient’s infectious disease issues. The award looks for the best paper or abstract that addresses improving the diagnosis, prevention and treatment of infections in immunocompromised cancer patients.

The award is open to current students, nurses, APPs, fellows or junior faculty with an appointment at the University of Washington, Seattle Children's Hospital or Fred Hutch Cancer Center.
