Groups2
Group 2 names the comparator: control.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Intervention - Aim 2 | During the intervention period, staff will capture women during the first well-baby visit (WBV) and offer to have the next visit co-scheduled for infant and contraception care. Appointments are scheduled during the discharge process at the end of each WBV. During the discharge process all women 0-6 months postpartum will be identified by clerical staff through review of each pediatric clinic beforehand and through an electronic flag alert in the infant's electronic medical record. The pre-review of pediatric clinic schedules and the use of the flag will remind staff to offer the mother a co-scheduled visit for newborn and contraceptive care at the time of the next newborn visit. | 595 | 1,461 | OG000 |
| Group 2 | Control - Aim 2 | Clinics will schedule postpartum contraception using normal clinic procedures. | 436 | 1,067 | OG001 |

Outcome
- Type
- SECONDARY
- Title
- Number of Patients Who Receive Contraception by Six Months Postpartum
- Description
Using de-identified patient data collected through clinic's Electronic Medical Record system (i.e., visit type attended, billing codes for contraception) we will measure receipt of all methods of contraception by six months postpartum
- Time frame
- 6 months
- Population
The stepped wedge design was interrupted for outcomes measured at six months due to a longer washout period, resulting in slightly different, yet overlapping samples for the primary and secondary outcomes.
