Meridian energy analysis may predict the prognosis of patients with advanced cancers receiving palliative care.

Abstract

A better understanding of irreversible prognoses in palliative care is crucial for improving patients' quality of life and their sense of dignity. We examined whether measurements of meridian electrical conductance can noninvasively and objectively predict survival time in a hospice patient population. This was a single-center cohort study. Between 2019 and 2020, we measured skin conductance from 24 representative acupoints of 12 meridians on both sides of the body in 181 advanced cancer patients within 48h of hospitalization and monitored their survival time. The Palliative Prognostic Score (PaP Score) was calculated for each patient, classifying them into one of three prognosis groups: Group A, B, or C. Factors associated with short-term and long-term survival were identified using multivariate regression analysis. Statistical differences in survival times were analyzed between the meridian electrical conductance measurements and PaP Scores. Analyses of the clinicopathological data from terminal cancer patients revealed that male sex, mean meridian electrical conductance measurements of ≤8.8μA, and PaP Scores in Group C were independent predictors of short-term survival. Mean meridian electrical conductance measurements of ≤8.8μA demonstrated good sensitivity (85.1%) and adequate specificity (60.6%) for short-term survival. A survival curve analysis revealed a mortality rate of 90.6% at 30 days among patients with meridian electrical conductance measurements of ≤8.8μA. A mean meridian electrical conductance measurement of ≤8.8μA can objectively assess short-term survival with advanced cancer and reduce nonbeneficial medical treatment.
