Complex Chronic Diseases Program (CCDP)

We treat and manage Myalgic Encephalomyelitis/Chronic Fatigue Syndrome, Fibromyalgia, and symptoms attributed to Chronic Lyme Disease.
At the Complex Chronic Diseases Program our goal for the program is to provide patient and symptom-centered care with the support of our interprofessional team of health care providers. 

We emphasize that treatment choice takes patient preferences into account, and that self-care is supported as well as treatment. Central to this is the development of partnership in care, and facilitation of patient involvement in assessment and in treatment decisions.

In the interest of ensuring the safety of our patients and staff, CCDP has postponed our in-person elective groups. We are currently connecting via zoom and phone. We will update the website when we resume in-person elective groups.

The Complex Chronic Diseases Program provides care for adults of all genders who are living with the following complex chronic diseases:

The Complex Chronic Diseases Program implemented a new model of care in early 2019 to better support our clients. Our program focuses on offering group-based education and self-management support, while continuing to offer 1:1 medical visits. This group education format is supported by client feedback and research. 

We have changed our model to increase client accessibility through telehealth and virtual health. Our model of care broadens our ability to support clients after they participate in our program and provide resources while they are on the waitlist.

The CCDP has an inter-professional team who bring different perspectives and expertise to your care and treatment plans.  All of the team members work together to collaborate with you around your care.

Our clerical team is responsible for scheduling your appointments. They will be your first point of contact with our clinic. 

Our medical team includes physicians, naturopath and pharmacist.

Our inter-professional team includes nurses, physiotherapist, occupational therapist, dietitian, social work and counseling. 

To participate in this program, you must have a completed referral form from your primary health care professional (such as a family doctor, nurse practitioner, naturopathic doctor) or specialist who will support your daily chronic disease management and follow your ongoing health. 

We will work directly with your primary health care professional to ensure that they receive information to provide you with the best available standards of care.

New patients during COVID-19

In keeping with the BC provincial health officer's advice to meet the requirements of social distancing, all our in person appointments and elective groups will be offered via telephone or postponed.

For new patients that will be contacted during this time, you may receive a phone call from our booking team to schedule a telephone self-management assessment with a clinician followed by a telephone medical consult with a physician. Please complete lab work (if requested) prior to your telephone physician assessment.

The physician will determine your eligibility for the CCDP. If you are accepted into the program, our booking team will contact you by phone to schedule your case-coordination appointments and provide a follow up email with medical visit handouts and a link to our introduction videos. The case-coordination phone calls with our team will assist you in selecting the elective groups you would like to take at CCDP.


Cancelled/Rescheduled/Missed Appointments

We require at least two full business days’ notice to cancel or to reschedule an appointment. This allows us to accommodate other clients who are waiting.

Due to the very high need for our service, if you miss three
appointments you will be discharged from our program. If there are barriers to your participation in the program, please let us know as soon as possible. You can contact our us at: (604) 875-2061

What is a CCD?

Complex chronic diseases, such as Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS), Fibromyalgia (FM), and symptoms attributed to Chronic Lyme Disease, are long in duration and there is no specific treatment.  In many cases, the causes of these diseases are unknown.

CCDs are called complex because:

  • The factors involved in causing these conditions are not well understood.
  • The symptoms and effects of any CCD can vary greatly among people with the same condition.
  • The longer duration of a CCD can lead to other health complications. These can include physical problems such as weakness, fatigue, and difficulty with daily activities (functionality). 
  • Any long-term illness can impair relationships, education and career goals, and affect a person’s mental health.
With all of these conditions, there are no blood or other laboratory tests to confirm a diagnosis. They are diagnosed based on symptoms described by the patient and medical assessment.

Each person with a CCD will experience their disease in a unique way, with symptoms that may or may not exactly match the most common descriptions. The most helpful approach to treatment will identify patients’ needs according to their symptoms and day to day functionality.

Even if you have had a CCD for a long time, there are steps you can take to feel better and gradually improve your condition. Having your CCD diagnosed as early as possible will help with a better and more rapid recovery.


The Complex Chronic Diseases Program provides care for patients who are living with the following complex chronic diseases:

Government of Canada invests $1.4M in biomedical research to improve the quality of life of people living with myalgic encephalomyelitis 

This $1.4M, five-year investment aims to improve the quality of life of people living with ME through:

  • investigating the causes of ME, including possible links to viruses and genes;
  • linking cohorts of patients and researchers in Canada and the US, enabling investigators to share research samples, clinical data, and analysis methods;
  • supporting graduate students working on ME to build Canadian capacity to research this condition; and
  • benefiting from the wisdom of people with ME who are active research partners.

BC Women’s welcomes Dr. Luis Nacul as the new Medical Director for the CCDP

We are thrilled to welcome Dr. Luis Nacul as the new medical director and research director of the Complex Chronic Diseases Program (CCDP). 

“We are very lucky to have Dr. Nacul join our team and lead CCDP,” says Dr. Stephanie Rhone, senior medical director, specialized programs, at BC Women’s. “Dr. Nacul will have dedicated research time in addition to his clinical and administration work, which is a huge asset to the program. His research expertise will inform the way we treat patients and open the door to new discoveries.”

Dr. Nacul is an internationally renowned leading clinician and researcher in his field with a broad understanding of complex chronic diseases treated at CCDP from medical, health services and research perspectives.

“It is a privilege for me to join such a dedicated team at one of a few centres in the world that specifically treats complex chronic diseases,” says Dr. Nacul. “I look forward to starting my new role and the opportunity to work in a collaborative environment that involves patient and community groups that are most affected.”

One of the challenges in treating complex chronic diseases is that their causes are unclear. In his capacity as CCDP research director, Dr. Nacul will leverage an established clinical program to expand research into complex chronic diseases. This is an important gain for the program, as CCDP patients with myalgic encephalomyelitis /chronic fatigue syndrome (ME/CFS), fibromyalgia syndrome and symptoms attributed to chronic Lyme-like disease will be able to benefit directly from research discoveries.

Dr. Nacul will also have an appointment as a researcher with the Women’s Health Research Institute. His research time is funded by the BC Centre for Disease Control (BCCDC) Foundation through its BCCDC Foundation Research Scholar Award.

New Model of Care Development

November 2018

The Complex Chronic Diseases Program is excited to announce that we are developing a new model of care to better support our clients. We are changing our current model to increase client accessibility through telehealth, build connections amongst clients, and reduce wait times between appointments. The new model of care will broaden our ability to support clients after they participate in our program and provide resources while they are on the waitlist.

‎Our new program will focus on offering group based education and self-management support, while continuing to offer 1:1 medical visits. This group education format is supported by client feedback and research. The new model of care will roll out in early 2019. As we develop this new model we will continue to see clients, and will communicate with our current clients about how this change may impact their journey with us. Please check back to the website for updates on our progress.
