Study information
Scientific title
Quality of care, obstetrical risk management and type of deliveries in Quebec: a multicentre, two arm, randomised cluster trial
Acronym
QUARISMA
Study hypothesis
Primary hypothesis:
The QUARISMA program will result in a 20% reduction in the rate of caesarean section (CS) among the hospitals following the intervention compared to control hospitals.
Secondary hypotheses:
This program will result in:
1. A reduction in materno-foetal morbidity, including a reduction in severe morbidity among low risk patients.
2. No augmentation in materno-foetal morbidity among high risk patients.

Caesarean section rate
Intervention
Audit Group Hospitals:
1. Society of Obstetricians and Gynaecologists of Canada provide training to health professionals (2 days at the year 2 and 1 day at the year 3)
2. Four self audit cycles with supervision by research team (3 months each), facilitated by a local opinion leader, starting at the sixth month of the second year for one year
3. Four other self audit cycles without supervision (3 months each) for another year
Control Group Hospitals:
Usual care.

Primary outcome measure
Caesarean section rate (total number of CS/total number of deliveries): data is collected every day from womens' clinical files during the 3.5 years of the program in the 32 hospitals (16 control and 16 interventions), to compare caesarean section rates in the intervention group with the rate in the control group at the end of the intervention period (year 3) and at the end of the follow-up period (year 4 or post intervention period).
Secondary outcome measures
Measured at the end of the intervention period (year 3) and at the end of the follow-up period (year 4 or post intervention period):
1. Caesarean section rate stratified by indications
2. Caesarean section rate stratified by type of CS (primary or repeat) and by the risk level of the delivery (high or low risk)
3. Vaginal birth after caesarean section rate
4. Obstetrical intervention rate
5. Maternal and neonatal morbidity
