Study Overview
Brief Summary
The purpose of this research is to evaluate the effectiveness of the Constipation Treatment Protocol and to test whether management according to dose of constipation-inducing medications or according to on-going assessment is most effective.
Detailed Description
Patients will undergo a baseline assessment during their regular outpatient visit. With their permission, the investigators will audio record this visit for quality control. After the study, the recordings will be erased. Patients will be asked to complete 4 questionnaires. The investigators will collect contact information so that the follow-up assessments can be done by phone.

- •are adults (or children 18-21 years old),
- •either male or female,
- •able to read and understand English,
- •and able to pass screening with the Short Portable Mental Status Questionnaire and Karnofsky Performance Status Scale.
Exclusion Criteria

- •if they are excessively debilitated or deemed unlikely to survive for the eight weeks of the data collection period;
- •if they are unable to read and understand English;
- •if they have an ostomy that changes bowel function;
- •if they have a current peritoneal catheter;
- •if they have had abdominal surgery within the past six weeks;
- •or have a disease process suggestive of mechanical obstruction (tumor or adhesion);

Arms & Interventions
Dose Intervention - Opioid
Laxative Treatment: Participants Receiving Opioids for the Treatment of Pain. Participants will be taken off any laxative preparation they may already be on and will be put on laxative treatment based on the Constipation Treatment Protocol. The dose of laxative will be based on the dose of the opioid pain medication they are receiving.
Intervention: Laxative Treatment (Other)
Dose Intervention - Opioid
Laxative Treatment: Participants Receiving Opioids for the Treatment of Pain. Participants will be taken off any laxative preparation they may already be on and will be put on laxative treatment based on the Constipation Treatment Protocol. The dose of laxative will be based on the dose of the opioid pain medication they are receiving.
Intervention: Assessment Questionnaires (Other)
Assessment Intervention - Opioid
Laxative Treatment: Participants Receiving Opioids for the Treatment of Pain. Participants will be taken off any laxative preparation they may already be on and will be put on laxative treatment based on the Constipation Treatment Protocol. The dose of laxative will be determined based on their severity of constipation.
Intervention: Laxative Treatment (Other)
Assessment Intervention - Opioid
Laxative Treatment: Participants Receiving Opioids for the Treatment of Pain. Participants will be taken off any laxative preparation they may already be on and will be put on laxative treatment based on the Constipation Treatment Protocol. The dose of laxative will be determined based on their severity of constipation.
Intervention: Assessment Questionnaires (Other)
Control Group - Opioid
Standard of Care: Participants Receiving Opioids for the Treatment of Pain will receive their usual care at Moffitt while participating in weekly assessments. After participation in the study is complete, participants will be offered the same protocol that is given to patients in the treatment groups.
Intervention: Standard of Care (Other)
Control Group - Opioid
Standard of Care: Participants Receiving Opioids for the Treatment of Pain will receive their usual care at Moffitt while participating in weekly assessments. After participation in the study is complete, participants will be offered the same protocol that is given to patients in the treatment groups.
Intervention: Assessment Questionnaires (Other)
Assessment Intervention - Vinca Alkaloid
Laxative Treatment: Participants Receiving a Specific Type of Chemotherapy (vinca alkaloids). Vinca alkaloids include medication such as Vincristine, Vinblastine, or Vinorelbine. Participants will be taken off any laxative preparation they may already be on and will be put on laxative treatment based on the Constipation Treatment Protocol. The dose of laxative will be based on their level of constipation.

Outcomes
Primary Outcomes
Phase I - Record Constipation Incidence and Symptoms
Time Frame: 18 months
To identify the incidence, severity, distress and trajectory of constipation in cancer patients receiving opioids over an eight week period and to evaluate the relationships between constipation intensity and opioid dose. To identify the incidence, severity, distress and trajectory of constipation in groups of cancer patients who may be at risk due to vinca alkaloids (vincristine. vinblastine. vinorelbine and vindesine) over an eight week period and to evaluate the relationship between constipation intensity and vinca alkaloid dose.
Secondary Outcomes
- Phase II - Number of Participants With Desired Effect - Patients with Medication-induced Constipation(2 years, 3 months)
- Phase II - Best Determination of Laxative Dose - Patients with Medication-induced Constipation(2 years, 3 months)
