Key findings

Forty-four percent (44%) of breast cancer patients, 48% of colon cancer patients and 62% of lymphoma cancer patients who receive chemotherapy visit the emergency department (ED) or are admitted to hospital at least once within 4 weeks of receiving chemotherapy. A high number of patients visit a second or third time. Side effects do occur and there is a need for patient education resources for patients to self-manage complications where appropriate, while also having a place where they can call or go when they require evaluation or a prescription.

What are chemotherapy, adjuvant chemotherapy and neutropenia?

In my words


I had a number of problems with chemo – lots of side effects – none of which anyone prepared me for or much assistance how to cope with them - I struggled through.

  • Chemotherapy are drugs that slow or stop cancer cells from growing, multiplying or spreading to other parts of the body1. Chemotherapy treatment can be pills, by injection or intravenously (IV).
  • Chemotherapy often is given in cycles to allow the body to rest and recover.
  • Adjuvant chemotherapy means that treatment is given after cancer surgery has appears to have removed the primary tumour. Adjuvant chemotherapy has shown to increase the chances of killing any remaining, non-visible cancer cells, to prevent recurrence (return) of cancer, to prolong life and to improve chances of cure in some patients.
  • In addition to destroying cancerous cells, chemotherapy drugs can suppress bone marrow function by killing white blood cells, which are essential for protection against illness and disease. As a result, patients may be more likely to develop infections.
  • A decrease in neutrophils, a type of white blood cell, is called neutropenia. If accompanied by a fever, it is called febrile neutropenia, and it can be a sign of an underlying infection.
  • In treating lymphoma, the most common combination of drugs that are used is a regimen called CHOP, which includes the drugs cyclophosphamide, doxorubicin, vincristine and prednisone. CHOP is often combined with immunotherapy, which aims to use our own immune system, or a man-made version of it, to fight disease2. Often, the antibody rituximab (Rituxan®) is used in combination with chemotherapy drugs (where it is known as R-CHOP).

What is the New Drug Funding Program?

  • The New Drug Funding Program (NDFP) provides equal drug access for all Ontarians by paying for chemotherapy regimens that have been evaluated and approved for coverage by the Ministry of Health and Long-Term Care.
  • This section measures how many breast, colon and lymphoma cancer patients being treated with NDFP drugs—either after surgery or as a primary treatment—needed to visit the ED 1 or more times for care and/or needed to be admitted to hospital within 4 weeks of receiving adjuvant chemotherapy, over the total duration of their treatment.

What is an unplanned visit during chemotherapy?

  • An unplanned visit occurs when a patient returns for an emergency department (ED) visit or is admitted to the hospital during a course of treatment.

    What do the results show?

    ED visits and hospital admissions are common (Figures 1 and 2).

    • Forty-two (42%) percent of breast cancer patients, 45% of colon cancer patients and 52% of lymphoma patients visited the ED at least once.
    • Of those who visited the ED, 23% of breast cancer patients, 19% of colon cancer patients and 43% of lymphoma patients were admitted to hospital.
    • In addition to the patients who visited the ED, 2% of breast cancer patients, 3% of colon cancer patients and 10% of lymphoma patients were admitted directly to hospital.
    • There is some regional variation in patients who visited the hospital during treatment, ranging from 31% to 67% for breast cancer patients, 37% to 70% for colon cancer patients and 51% to 73% for lymphoma patients.
    • It should be noted that EDs in northern regions may admit patients directly to hospital.
    • Many of these patients were visiting the hospital due to neutropenia, fever or infection (data not shown). Other reasons for an unplanned ED visit include pain and unrelated reasons. Due to some data limitations, some of the reasons for many of these visits are not available.
    • Uplanned hospital visits also are reported on after cancer surgery and during radiation treatment .

     Almost half of patients with breast or colon cancer visited the ED a second time during a course of treatment. Percentages were even higher for lymphoma patients (Figures 3 and 4).

    • Nearly 50% of breast and colon cancer patients returned for a second ED visit, with approximately another 25% returning for a 3rd visit; 59% of lymphoma patients returned a second time, and 36% returned a third time.
    • For breast and colon cancer patients, 6% and 7% (respectively) returned to the hospital 5 or more times (compared to 12% of lymphoma patients).
    • Hospital visits differed by age and type of cancer. Breast cancer patients ages 18 to 29 had the highest rates (63%) of visiting the hospital, compared to breast cancer patients ages 80 and over (29%).
    • Colon cancer and lymphoma patients had the highest hospital visits for patients ages 65 and older.
    • These differences in age could be related to younger breast cancer patients being treated with more aggressive regimens of chemotherapy drugs than lymphoma and colon cancer patients, who all would receive the same regimen.

    Many hospital visits are happening during the day, with hospital admissions varying by type of cancer and time of day (Figures 5 and 6).

    • Approximately one third of hospital visits took place during weekday business hours. About 30% for breast cancer, colon cancer and lymphoma patients returned on the weekend.
    • Patients were more likely to only visit the ED than be admitted during weekday business hours and on the weekend.
    • The weekday overnight time period had the highest rate of hospital admission for breast cancer, colon cancer and lymphoma patients.
    • Lymphoma patients had the highest rate of admission to hospital for any time of day—particularly the weekday overnight time period, when 67% of patients were either admitted directly to hospital or via the ED.
    • The differences seen between the types of cancer and the time of visit may reflect patients experiencing more serious symptoms.
    • This analysis helps identify which visits may be preventable with better symptom management supports in the cancer system.

    Why is this important to patient care?

    Managing treatment-related side effects.

    • While adjuvant chemotherapy for breast cancer, colon cancer and lymphoma patients has helped improve outcomes, the potential for drug-related side effects must be taken into account when balancing improvement in survival with aggressiveness of treatment.
    • There is no standard for an acceptable rate of chemotherapy side effects.
    • These drug-related side effects are potentially predictable, and they should be taken into account when setting individual treatment plans and planning for appropriate system resources to care for these patients.
    • By measuring hospital visits resulting from the effects of chemotherapy treatment, Cancer Care Ontario aims to improve patient management and care in the following ways:
    • by ensuring patients know who to call for side effects; and
      • eliminating unnecessary visits to the ED.
    • In the 2014 Ambulatory Outpatient Patient Satisfaction Survey (AOPSS), 83% of breast and colorectal cancer patients and 82% of lymphoma patients responded that someone had either “yes, completely” or “yes, somewhat” told them how to manage any side effects of chemotherapy (data not shown).
    • This suggests that the problem is not whether information is being provided, but how and what information is being provided and how it is being used by patients. The hospital may be the appropriate place to evaluate and help certain patients, but there may be other acceptable options as well.
    • Provision of alternative strategies and clinics to deal with these patient issues outside of normal working hours would seem to be an appropriate goal.

    Neutropenia, fever and infection may be preventable.

    • Growth factor (e.g. G-CSF) has been shown to decrease the rates of neutropenia after intravenous chemotherapy3.
    • Using growth factor preventively after some adjuvant chemotherapy regimens may help reduce the rates of neutropenia and its complications.

    Appropriateness of using the emergency department and hospital care.

    • Medical oncologists instruct patients to go the emergency department if they experience serious side effects (such as fever) outside of normal clinic hours because fever after chemotherapy needs to be evaluated quickly, and there are no other appropriate healthcare settings to receive the patients (when clinics are closed).
    • Cancer treatment planning should include follow-up care needs and required resources.
    • From the point of view of cancer patients, emergency departments may not be the most appropriate care setting for support, treatment or management of all side effects. Other models of care could be considered, such as management of low-risk patients by urgent care centres.
