Key issues in MOD debates
Cesarean rate Safety Access

Cesarean rate
Why be alarmed?
Resource allocation/cost containment
Justice and responsible stewardship
Judgment about the “right” way to deliver
Provider, patient, society – whose view?
Access to preferred delivery mode Practice patterns ↓ low intervention birth

Safety
Which risks are reasonable, by whatmeasure, according to whom?
What justifies directive guidelines? Cognitive challenges to risk reasoning
Low risk of very bad outcome
Trade-offs with valued higher probability,often extra-medical outcomes
Weighing maternal and fetal interests

Access
Guidelines have potential to constrain
Example: VBA C
1990s – limited access to RCS 2000s – limited access to VBAC
Access to options ≠ autonomy Too many options ↓ autonomy
Availability of certain options to some women
↓ options for others (CDMR)

Challenges
Aggregation
Central tendency vs. distribution
Population vs. individual patient
Swamping
Discrete outcomes, institutional goals, provider views
“Quixotic quest”
Context
Patient values
Risk elsewhere (clinical, daily life)

Conclusions
Responsible guidelines are a function of fourconsiderations
Safety and efficacy, cost-effectiveness, externalities,
patient preferences
Responsible guidelines require understandingand instituting distinctions
Non-directive, presumptive, prescriptive, restrictive
Responsible guidelines require attending tochallenges of risk and value
