PIDS was developed by CDC and housed on CDC secured servers. All data collection activities are managed and tracked using the PRAMS Integrated Data Collection System (PIDS), a web-based customized tracking system. For each of these monthly samples, or “batches,” this sequence of mailing contacts is attempted. Each month, a stratified sample is drawn from the current birth certificate file.
The data collection cycle from the mailing of the pre-letter to the close of telephone follow-up lasts approximately 60 to 95 days. The survey contains questions about the early postpartum period thus, the mailings are timed to ensure that all women will be able to respond for this period.
Tailor tales plus code series#
The series of mailings begins commences two to four months after delivery. Telephone follow-up is initiated for all mail nonrespondents 7 to 14 days after mailing the last questionnaire. This third packet is sent to all remaining nonrespondents 7 to 14 days after the second questionnaire. This packet is sent to all sampled mothers who have not yet responded 7 to 14 days after the tickler has been sent. It is sent 7 to 10 days after the initial mail packet. The tickler serves as a thank you and a reminder note. This packet is sent to all sampled mothers 3 to 7 days after the preletter. This letter introduces PRAMS to the mother and informs her that a questionnaire will soon arrive. Here is the sequence of contacts for PRAMS surveillance:
2 A key aspect of his approach is to make numerous and varied contacts with sampled mothers. The principles and practices of mail/telephone survey methodology used by CDC are based primarily on the research of Don Dillman. PRAMS combines two modes of data collection a survey conducted by mailed questionnaire with multiple follow-up attempts, and a survey by telephone. 1 Each site follows the protocol, but also has the opportunity to customize some portions of it to tailor the procedures to the needs of the jurisdiction. The standardized data collection methodology is prescribed in the CDC Model Surveillance Protocol. This standardized approach allows for comparisons among sites and for optimal use of the data for single-jurisdiction or multi-jurisdiction analysis. One strength of the PRAMS surveillance system is the standardized data collection methodology.
