Post-disaster health indicators for pregnant and postpartum women and infants.

United States (U.S.) pregnant and postpartum (P/PP) women and their infants may be particularly vulnerable to effects from disasters. In an effort to guide post-disaster assessment and surveillance, we initiated a collaborative process with nationwide expert partners to identify post-disaster epidemiologic indicators for these at-risk groups. This 12 month process began with conversations with partners at two national conferences to identify critical topics for P/PP women and infants affected by disaster. Next we hosted teleconferences with a 23 member Indicator Development Working Group (IDWG) to review and prioritize the topics. We then divided the IDWG into three population subgroups (pregnant women, postpartum women, and infants) that conducted at least three teleconferences to discuss the proposed topics and identify/develop critical indicators, measures for each indicator, and relevant questions for each measure for their respective population subgroup. Lastly, we hosted a full IDWG teleconference to review and approve the indicators, measures, and questions. The final 25 indicators and measures with questions (available online) are organized by population subgroup: pregnant women (indicators = 9; measures = 24); postpartum women (indicators = 10; measures = 36); and infants (indicators = 6; measures = 30). We encourage our partners in disaster-affected areas to test these indicators and measures for relevancy and completeness. In post-disaster surveillance, we envision that users will not use all indicators and measures but will select ones appropriate for their setting. These proposed indicators and measures promote uniformity of measurement of disaster effects among U.S. P/PP women and their infants and assist public health practitioners to identify their post-disaster needs.
