DMS v.1
DeMeester Score (DMS) for GERD measures acid exposure to diagnose gastroesophageal reflux disease (GERD).
To calculate the total sum for the DMS.
Use to aid with diagnosis of GERD. The score measures acid exposure during prolonged ambulatory pH monitoring, through a composite score resulted from six parameters. For each of the six, a scoring value SVn = ((X-A)/SD) + 1 is calculated, where X = detection value, A = mean value, SD = standard deviation. The DMS is be obtained by adding the six sets of scoring values: DMS = SV1 + SV2 + SV3 + ... + SV6. The interpretation of the score is as follows: DMS <14.72 No GERD DMS 14.72 – 50 Mild GERD DMS 51 – 100 Moderate GERD DMS >100 Severe GERD
