i3 Innovus/ Ingenix Data Analysis
  • Retrospective claims analysis from a large
    national health care plan database
  • 14 million commercial health plan members with a
    specified MIS or open surgical procedure from
  • Inclusion Criteria Surgical procedure for an
    MIS or open procedure from July 1, 2005-June 30,
  • Reviewed duration and cost of the
    procedure-related episodes of care

Study Objectives
  • Describe and compare the surgery-related outcomes
    for the specified minimally invasive and open
    procedures (severity risk adjusted) including
  • Length of hospital stay (LOS)
  • Re-admission rates
  • Total procedure-related costs
  • Identify complication rates and costs including
  • Infection
  • Bleeding (major and minor)
  • Procedure-specific complications (e.g.,
    peritoneal adhesions, bowel perforation)
  • The primary outcomes assessed in surgical cohorts
  • post-surgical office visits
  • outpatient visits
  • inpatient visits
  • length of stay
  • total health care costs
  • APP-area procedure costs
  • chest-area procedure costs
  • postsurgical complication rates
  • associated costs
  • duration of episode of care
  • cost of episode of care
  • bleeding rates (both major and minor)
  • post-surgical infection rates

i3 Ingenix Data Analysis Conclusions
  • The study results have shown that open surgical
    procedures are generally associated with
  • higher health care utilization and
  • higher costs for most of the studied procedures
  • The study indicates that there is ample
    opportunity to optimize the use of health care
    resources and minimize the cost of care by
    increasing the use and awareness of MIS relative
    to open surgery

Clinical Evidence for MIS

Appendectomy, Cholecystectomy Colectomy.
MEDLINE literature analysis of randomized
controlled published studies between 2004-2008.
Specialty Society Perspective
  • Add SAGES information
  • Describe FLS program

Nosocomial Infections
  • Noting that patients who develop surgical
    infections spend, on average, an additional 6.5
    days in the hospital and are twice as likely to
    die, the report recommends that all hospitals
    report and publish surgical infection rates and
    suggests that the federal government tie Medicare
    payments to compliance with surgical prevention
    measures (Consumers Union report, April 2009
    Consumer Union release, 4/27 Stockton Record,

Challenges to Increased MIS Adoption
  • Surgeon training and resistance to change
    clinical behavior
  • Initial investment in training and skills is
    required for the surgeons to deliver MIS- the ROI
    may not be immediately realized
  • Seasoned surgeons may continue to perform
    surgeries with same technique
  • Lack of patient awareness
  • Many patients arent aware of their surgical
  • Lack of incentives or misaligned incentives
  • No incentive to change clinical behavior
  • Consumer/patient incentives
  • Lack of PCP awareness and referral patterns
  • May not be up to date on latest surgical options
    or specialists who perform MIS
  • Referral may be made to surgeons who dont
    perform MIS
