Indicated Labor Induction Phase One: Protocol Development Peter Cherouny, M.D. University of Vermont Department of OB/GYN

Indicated Labor Induction Phase One: Protocol Development Objectives –After the presentation the participant will be able to: –Articulate the risks of proposed obstetric care to the patient –Incorporate the risks of care into patient care discussions –Recognize the absolute level of risk of fetal death at term

Indicated Labor Induction Phase One: Protocol Development To Induce or not to Induce Setting the Stage

The Cost of Oxytocin

The Real Cost of Oxytocin The costs to the patient from coming to us for care: Safety Risk and Cost

Focus on the group with the highest variability for Primary Cesarean delivery (by provider or institution) Term IUP Cephalic presentation No contraindications for labor/vaginal delivery

Focus on the group with the highest variability for Primary Cesarean delivery (by provider or institution) First term pregnancies (without prior labor) Multiparous term with a prior vaginal delivery The Intention is to treat these women with vaginal delivery How many patients are there?

Focus on the group with the highest variability for Primary Cesarean delivery (by provider or institution) How many of our patients? –70% deliver vaginally70% –70% primary cesarean sections21% have indications that did not 91% preclude labor Failure to induce, dilate or descend elective cesarean

Focus on the group with the highest variability for Primary Cesarean delivery (by provider or institution) Remember The Intention is to treat these women with vaginal delivery

Our 91%er

Because we have pitocin, we… (Term IUP, cephalic presentation, no labor) Induce labor(25%) -10% elective IOL

Because we have pitocin, we… (Term IUP, cephalic presentation, no labor) Augment labor(30%) –Induction vs augmentation What’s your definition

By Delivery Type Term IUP, cephalic presentation Spon labor Vaginal Delivery Pitocin labor Vaginal Delivery or C/S Spon Labor Cesarean Section

By Labor Type Term IUP, cephalic presentation Spon labor Pitocin Labor Cesarean Section Vaginal Delivery

Because we have pitocin, we… Term IUP, cephalic presentation Induce or Augment labor (55-90%) –What’s the patient pitocin exposure in your L&D?

Because we have pitocin, we… Term IUP, cephalic presentation, no labor Induce labor(25%) –Increase nursing time 1:2 for active labor –Increase provider time in hospital in active labor –Increase analgesia use 90% with IOL, 100% with OVD

Because we have pitocin, we… Term IUP, cephalic presentation, no labor Induce labor(25%) –Increase OVD 2-3 fold Relative Risk –Increase cesarean sections 2-3 fold Relative Risk –Increase general anesthesia 5% of cesarean sections –Increase NICU admissions 2-4 fold RR at Term

Because we have pitocin, we… Term IUP, cephalic presentation Induce or Augment labor leading to C/Section –Increase postpartum hemorrhage RR % requiring transfusion –Increase postoperative DVT/PE Common cause of maternal mortality –Increase hospitalization (nosocomial infection, etc.) –Increase AFE (amniotic fluid embolus) –3-4 fold RR after IOL –12 fold RR after Cesarean section

Because we have pitocin, we… Term IUP, cephalic presentation Induce or Augment labor leading to C/Section –Increase postpartum/cesarean hysterectomies 3 fold RR of placenta previa after 1 cesarean section 45 fold RR after 4 or more prior Cesarean deliveries 5 fold RR for placenta accreta after 1 Cesarean delivery 11 fold RR with 2 prior Cesarean deliveries 0.25% (1987); 0.82% (2006) –Increase time of recovery 3-4 vs 1-2 days for initial recovery –Increase costs to business (time away and insurance)

Because we have pitocin, we… Term IUP, cephalic presentation Induce or Augment labor leading to C/Section –Increase antibiotic exposure 5-10 fold RR –Increased fetal injury 1-2% at Cesarean Section –Increase organ injury 2% at cesarean delivery 5% at hysterectomy –Increased abdominal scarring Small Bowel Obstruction 0.5/1000

Because we have pitocin, we… Term IUP, cephalic presentation Induce or Augment labor leading to C/Section –Increased ectopic pregnancies –Increased narcotic use/abuse –Increased infertility 1.5 RR of infertility after cesarean delivery –Increased time to first breastfeeding –Decreased bonding –Decreased birth experience

Oxytocin Costs Summary 4.3 million USA deliveries (2007) X 25% induction rate = 1.08 million Labor Inductions X 31.3% Cesarean Section Rate = 1.31 million Cesarean Sections –Even low incidence outcomes become important

The Reliability Design Strategy Prevent initial failure –intent and standardization function Identify failure (defects) and mitigate –Redundancy function Measure and then communicate learning from defects –Redesign function

Why Standardize? Contributes to building an infrastructure (who does what, when, where, how and with what) Support training and competency testing to sustain the process Achieve front line articulation of key processes by staff Allows the appropriate application of Evidence Based Medicine consistently Feedback about errors and application of learning to design is possible

The Clinical Bundle as Standardization

What is a Clinical Bundle A group of clinical events that should happen every time a given process occurs Individual elements based on solid science Emphasis initially on process rather than outcome Based on failure modes Eventual endpoint is outcome improvement

Quality Care in Obstetrics Elective Labor Induction-Requirements Elective Oxytocin Labor Induction Bundle  Gestational age > 39 weeks  Category I EFM  Absence of tachysystole with increases in pitocin/Response to tachysystole  Pelvic assessment

Quality Care in Obstetrics Augmentation-Requirements Oxytocin Augmentation Bundle  Estimated fetal weight  Category I and some Category II EFM  Absence of tachysystole with increases in pitocin/Response to tachysystole  Pelvic Assessment

Quality Care in Obstetrics Indicated Labor Induction Bundle Defined: Patient with a medical indication for induction Acceptable medical indication for labor induction documented (locally defined) Pelvic Assessment Recognition and management of complications of induction method (including tachysystole) Recognition and management of FHR Status –Exclusion of Category III FHR
