A Review of Prenatal Group Care Literature: The Need for a Structured Theoretical Framework and Systematic Evaluation
Brief description: The purpose of this article is to systematically review the literature on group-based prenatal care related to patient participation, attendance, satisfaction, knowledge, pregnancy and birth outcomes, and program cost outcomes.
Major Findings: Based on our systematic review, the CenteringPregnancy group model of prenatal care is showing some promise. The participants who enroll in group care like it and are satisfied with it. There appear to be some improved outcomes among patients who chose group care. However, these findings must be interpreted cautiously. The reliability of the findings is limited by the quality of the studies’ designs. CenteringPregnancy groups function to bring women together to interact and learn from each other as they share the common experience of pregnancy. Most of the studies we reviewed promote group care as a better option for patients than traditional individual care. However, with further study, we hypothesize that group care may be a good option for some patients but not all. Research on group care would benefit from additional randomized controlled trials that assess cost and sustainability and formally evaluate group process and intermediary factors thought to account for improved outcomes.

TREAT: Tamper-Resistant Envelope Allocation Technique for a Multisite Study
Brief description: In randomized-controlled trials, allocation concealment is essential to prevent group assignment tampering, maintaining integrity of the randomization and study findings. We developed a low-tech, low-cost, tamper resistant, randomized allocation process [tamper-resistant envelope allocation technique (TREAT)] for multi-study clinic setting use.
Major findings: The TREAT method is novel because it expands on other methods as it can be used remotely, is free from computer or phone requirements, has enhanced verification with specific measures to ensure recruiter and participant information is recorded in multiple locations simultaneously, and adds extra layers of protection to discourage tampering with randomization. TREAT maximizes concealment and creates an enhanced audit trail for increased assurance. TREAT is easy to implement and inexpensive to create, making it a viable option for projects.
