Summary
Brief summary (as posted)
This trial studies how well rectal administration of opioids using the Macy catheter works in reducing pain in patients with cancer that has spread to other anatomic sites or is no longer responding to treatment. Rectal administration of opioids using the Macy catheter may help to reduce the cost of care, resolve the issue of medication availability currently faced in the form of parenteral opioid shortage throughout the country, and provide adequate comfort and symptom relief for patients with smoother transition out of hospital.

Primary outcomes (1)
- measure
- Feasibility of using the device 'Macy catheter' for rectal administration of opioids for comfort in cancer patients on palliative care as defined by number of doses administered and patient satisfaction
- timeFrame
- Up to 1 year
- description
- Will be assessed by the number of doses that a patient finishes (at least 4 out of 6 doses administered) and by asking patients' about their level of satisfaction and overall perception of effectiveness of using the device, collected by question 10 and 11 in the survey, respectively. The association between patients' demographics and clinical characteristics and patients' satisfaction and perception of effectiveness will be evaluated by Wilcoxon rank sum test and chi-square (or Fisher's exact) test for continuous and categorical variables, respectively. In order to address the primary objective, the feasibility rate will be estimated and reported along with a 95% Clopper-Pearson exact confidence interval.
