As a nurse treating hospice or palliative care patients with advanced illness, you may sometimes find yourself needing to talk more openly with your patients’ doctors about issues related to OIC.

Here are some thoughts to keep in mind during such conversations:

  • OIC is one of the most distressing side effects seen in palliative care patients5,6
  • OIC can cause or result in abdominal pain, nausea and vomiting, or fecal impaction5,6
  • OIC can last the entire time that a palliative care patient with advanced illness is taking opioid medication2,7

You are not alone

In a survey of 502 hospice/palliative care nurses*:

  • 84% said that at least half of their terminally ill patients deal with OIC at some point3
  • 87% ranked constipation among the top three side effects they believe their terminally ill patients taking regular doses of opioids find the most frustrating3

* Based on a sample of member nurses provided by the Hospice and Palliative Nurses Association (HPNA) and sponsored by Wyeth Pharmaceuticals. At least 25% of the nurses’ patient populations took regular doses of opioids and at least 25% had a terminal diagnosis with a life expectancy of 6 months or less. Survey was conducted by Harris Interactive from March 26 through April 20, 2007.
