National Household Health Survey
National Healthcare Research Foundation — United States
Overview
Client: National Healthcare Research Foundation
The Challenge
A national healthcare research foundation needed to conduct a nationally representative household health survey covering 12,000 in-person interviews across seven key states within a 12-month fieldwork window. Previous vendors had struggled with response rates below 80% in urban areas and faced significant challenges recruiting and retaining qualified interviewers in rural regions. The organization required a minimum 90% response rate to meet statistical validity thresholds for key health indicators used in policy decisions.
Our Solution
Ginger Research deployed over 280 trained field interviewers organized into 28 regional teams, each managed by an experienced field supervisor. We implemented a multi-contact protocol combining advance letters, in-person visits, and telephone follow-ups to maximize respondent cooperation. Our proprietary CAPI platform enabled real-time monitoring of response rates at the county level, allowing field managers to dynamically reassign resources to underperforming areas. We also developed culturally adapted interviewing protocols and provided interviewers with language-specific training for Spanish, Mandarin, and Vietnamese-speaking households.
Results
- Achieved a 94% overall response rate, exceeding the 90% contractual threshold
- Completed all 12,000 interviews within 11 months, one month ahead of schedule
- Maintained a 99.2% data accuracy rate verified through independent back-checks
- Received commendation from the client for the highest response rate in the survey's 20-year history
