José Enrique Pérez Lu MD MSc PhD (c) Universidad Peruana Cayetano Heredia

Introduction Maternal and child care is one of the Millennium Development Goals Information and communication technologies (ICT) are an opportunity to improve health: Electronic Health Records Use of cell phones
3
WawaRed “Wawa” means baby in Quechua, and “Red” means network in Spanish Includes: Text messages (SMS) Advice about pregnancy, appointment reminders, prevention and motivational messages. Electronic health record for maternal care Interactive voice response (IVR) system: Messages about danger signs during pregnancy. The main objective is to improve maternal and child care We designed a RCT to evaluate the impact
4
Electronic Health Record
Phone calls Personalized SMS SMS Platform IVR Central Electronic Health Record Secure Database WawaRed Portal Data collection
5
Developing the SMS: First step - Needs assessment
Focus groups with pregnant women for knowing their preferences about the type of text messages that they want to receive Second step – Assess program acceptability Focus group with pregnant women for validate the messages that we had done Third step - Assess technological feasibility Pilot with 92 pregnant women for test the system The 93% were "very satisfied " to receive SMS
6
Type of SMS Motivational Education (Nutritional, Pregnancy Warning Signs) Appointment Reminders (2 days before each visit) Specific (Hyperemesis, Obesity, Malnutrition, Anemia, hypertension, diabetes, Urinary infection, Syphilis, HIV, fever, TB, Alcohol, Drugs, etc) We sent the SMS on Monday, Wednesday and Saturday at 9:00 am each week
7
"Mommy rejoice and go to your clinic visit"
“Going to your ANC visit is not losing all morning, it is gaining health for your baby” “Consume iron to have energy and prevent anemia, it can be found in foods like : liver, spleen, and red meat” "Mommy rejoice and go to your clinic visit" “Keep going, you're in the middle of your pregnancy, and your baby is getting bigger and stronger”
8
Randomized clinical trial of the impact of the SMS
Sample size: 1300 Power: 80% Principal outcome: Percent of pregnant women attending at least 6 ANC visits Difference between 60% - 68% Secondary outcomes: Median of n of ANC visits Delta of blood hemoglobin Percent of women with vomiting that go to ER Percent of women with difficulty seeing that go to ER Average weight of infants
9
Results: Women receiving the SMS messages compared to women who didn’t showed: 10% higher number of antenatal care visits according to schedule The average number of women with 6 ANC visits is 5% higher in the intervention group than in the control group 7% higher women with 9 or more ANC visits in the intervention group compare with the control group.
10
Results: SMS were more effective among :
Women with secondary or higher education 13% higher number of ANC visits on time Increase their vitamin adherence during: The last week of pregnancy by five percentage points The last month of pregnancy by three percentage points Increase APGAR score (1 minute) by 0.14 Women who live closer to the health center: Increased vitamin intake compliance during the last month of pregnancy by three percentage points A positive effect on newborn birth weight equivalent to grams
11
Results: Intervention was more effective within the group of women with at least secondary school and who live closer to the health center Improved the total number of ANC visits attended by visits Total number of ANC visits on time increased by 0.58 Vitamin intake during the last week and month of pregnancy was also increased by 12 % Increase the weight of newborns by grams Increase APGAR score (1 minute) by 0.16 point

WawaRed Rural: Better health in maternal care in Rural Areas
Voice messages in Spanish and Quechua in rural areas: Advice about pregnancy, appointment reminders, prevention and motivational messages
13
Developing voice messages:
First step - Need assessment Focus groups with pregnant women Not want SMS Prefer voice messages in Spanish and Quechua They wanted their partners also receive messages Second step – Assess program acceptability Focus group with pregnant women for validate the messages that we had done Third step - Assess technological feasibility Pilot with 10 pregnant women for test the system
14
Evaluation of the program:
Randomized clinical trial of the impact of voice messages with 208 pregnant women In deep interviews with 10 pregnant women
15
In deep interviews: “It helped (the voice messages) to remind myself to take my iron with orange juice” “When WawaRed called me, I felt it was as if my mother was calling me and giving advice” “The messages taught me what I have to do for a successful pregnancy. And now I'm teaching my sister who is pregnant” “With the messages I learned to eat well, so my baby is chubby” “With the messages I learned what the warning signs in pregnancy are. If I felt any discomfort I should go to the health center”
16
Conclusions: SMS increased the number of ANC visits, vitamin adherence, APGAR score and newborn birth weight SMS were more effective within the group of women with at least secondary school and who live closer to the health center In rural areas pregnant women prefer voice messages over SMS They feel that the messages help to educate them on how to have a good pregnancy
