Palliative Care Assessment Calculator

The Edmonton Symptom Assessment System, revised (ESAS-r), is a widely used palliative and oncology symptom-tracking tool validated by Watanabe and colleagues in a 2011 multicenter study, that has patients rate nine domains -- pain, tiredness, drowsiness, nausea, appetite loss, shortness of breath, depression, anxiety, and poor wellbeing -- each on a 0-to-10 scale, from none to worst possible. This calculator sums the nine ratings into a total symptom distress score (0-90) and splits that same sum into a physical subscore (the first six domains) and a psychological subscore (depression, anxiety, and wellbeing), with every domain weighted identically at one point per point scored -- there is no domain in ESAS-r that counts more than another toward the total. The per-item severity bands (1-3 mild, 4-6 moderate, 7-10 severe) are validated in the ESAS-r literature (Selby et al.), but the 0-90 total-score bands (mild under 28, moderate 28-54, severe 55+) and the three-path referral rule below are this calculator's own synthesis, not a separately published or validated total-score instrument -- treat them as a reasonable organizing framework, not an established clinical threshold in their own right. Referral criteria are evaluated through three independent paths, any one of which is sufficient on its own: a total score of 28 or higher, any single symptom scored 7 or higher (individually severe), or at least three symptoms each scored 4 or higher (moderate burden spread across multiple domains).

That third path means a patient without any single severe symptom and without a high total score can still meet referral criteria purely from breadth -- several moderately troubling symptoms occurring together, none alone dramatic, is itself a recognized clinical pattern that warrants attention rather than something that only a single dominant symptom or a high cumulative total can trigger, though this specific "3 symptoms at 4+" rule is this tool's own operationalization of that idea rather than a cited criterion. This tool does not implement the Palliative Performance Scale (PPS), a separate functional-status instrument sometimes used alongside ESAS-r -- only symptom distress scoring is computed here. ESAS-r captures symptom intensity as the patient reports it in the moment; it does not measure symptom duration, functional impact, or caregiver burden, and a single completed assessment is a snapshot, not a trend -- serial ESAS-r scores over time are what typically guide palliative care management decisions in practice.
