The Johns Hopkins Hospital, Baltimore, Maryland (Phase I)

  • Waiting time for emergent/urgent surgical cases decreased by 39%
  • Throughput increased by 5 cases per day in the main ORs and by 4 cases per day in their outpatient facility
  • Overtime decreased by 6.6%
  • Relative increase in surgical volume resulting in annual $4 million increase in incremental margin

Boston Medical Center, Boston, MA (Phase I and Phase II in one unit)

  • Surgical throughput increased by 10%
  • Emergency Department ambulance diversions reduced by 20%
  • 2.8 hour wait in one of the state’s busiest EDs compared to 4-5+ hours for most academic hospitals in Boston
  • Annual number of postponed or cancelled elective surgeries reduced by 99.5%

  • 3% increase in surgical volume
  • 38% decrease in weekday waiting time for non-elective cases
  • Opportunity to further increase surgery volume with $8m projected annual margin increase with $2 million achieved in the first year

HackensackUMC Mountainside, Montclair, NJ (Phase I)

  • Improved elective OR block utilization resulting in increased capacity for 1,000 cases annually without additional resources

Great Ormond Street Hospital for Children, London, England (Phase II)

  • An average increase of 2.2 cardiothoracic theatre procedures per week (representing a minimum increase in annual revenue of £1.72 million), meaning that they can treat more children urgently requiring specialist surgery
