Prognostic prediction has been reported to affect the decision of doctors and non-physician health care providers such as nurses, social workers, pastors, and hospice volunteers on the selection of appropriate medical interventions. This was a case of a 65-year-old woman who presented with a poor oral intake. The patient had a history of sigmoid colon cancer with abdominal wall metastasis and peritoneal dissemination. On the day of admission, nausea, anorexia, and malaise were noted, requiring immediate intervention. The patient’s prognosis was predicted using the Palliative Prognostic Index. The pharmacist suggested the use of dexamethasone tablets in order to alleviate the patient’s symptoms. Indeed, the administration of dexamethasone alleviated the symptoms of nausea, loss of appetite, and malaise. To the best of our knowledge, this is the first case report to demonstrate that prognosis prediction is important not only for other medical staff but also for pharmacists when deciding the need to initiate a treatment and continue such treatment, and when providing pharmacist interventions.
