About
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.
Full 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.

601 participants in 5 patient groups
Dose Intervention - Opioid
Active Comparator group
Description:
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.
Treatment:
Other: Assessment Questionnaires
Other: Laxative Treatment
Assessment Intervention - Opioid
Active Comparator group
Description:
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.
Treatment:
Other: Assessment Questionnaires
Other: Laxative Treatment
Control Group - Opioid
Other group
Description:
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.
Treatment:
Other: Assessment Questionnaires
Other: Standard of Care
Assessment Intervention - Vinca Alkaloid
Active Comparator group
Description:
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.
Treatment:
Other: Assessment Questionnaires
Other: Laxative Treatment
Control Group - Vinca Alkaloid
Other group
Description:
Standard of Care: Participants Receiving a Specific Type of Chemotherapy (vinca alkaloids). Vinca alkaloids include medication such as Vincristine, Vinblastine, or Vinorelbine. Patients will receive standard of care 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.
