- Midwives successfully completed training to use safe+natal at high rates: 80% passed proficiency tests on the first try, 98% after the second try.
- Detection of key pregnancy complications, particularly hypertensive disorders, increased.
- Successful referral rates to medical facilities for life-threatening conditions significantly increased.
