Postoperative Care

with PrevisEA


PrevisEA is precision medicine, personalizing postop care decisions to individual patient digestive health.


Previs is placed on the abdomen of the patient within one hour of surgery


An acoustic biomarker, MH4,1 is quantified at postoperative hour 12 to determine the patient’s Previs™ Index


The patient Previs Index is displayed as “High Risk” or “Low Risk”  for development of gastrointestinal impairment

PrevisEA™ assesses the digestive health of postop patients, determining individual risk of GII, informing refeeding decisions, which may optimize length of stay and reduce readmissions.

Early Oral Refeeding

Precision Postop Care with PrevisEA

In early oral refeeding PrevisEA may:

  • Reduce readmission from current 20% to <5%
  • Reduce at home incidence of downstream adverse events of POI

In delayed oral refeeding PrevisEA may:

  • Result in earlier oral refeeding for low-risk patients
  • Reduce length of stay length of stay by as much as 3 days in low- risk patients

Benefits of PrevisEA in Postoperative Care

PrevisEA brings precision medicine to postoperative care by personalizing refeeding and discharge decisions. Digestive health is assessed to determine each postoperative patient’s individual risk of gastrointestinal impairment.

Benefits with PrevisEA

  • Determines individual patient risk of GII
  • Risk-based standardization of re-feeding and discharge strategies using precision medicine, which may:
    • Assist in determining if early oral refeeding and early discharge are appropriate
    • Optimize length of stay based individual patient risk of GII
    • Reduce readmissions, improve patient outcomes, and lower cost of care
