January 5, 2018 – Gunnison, a Major Player in NHANES Mobile Data Collection Technology


« « prev| next » »

The National Health and Nutrition Examination Survey (NHANES) is looking to mobile technology strategies in an effort to improve survey response rates.  One such strategy involves a custom implementation of the Westat proprietary Mobile Field Operating System (MFOS).  Gunnison has played a key role in integrating the proprietary software with existing NHANES infrastructure.

This customized iPhone application is being used by data collectors to record Electronic Record of Contacts (EROC), location data, appointments, hours and record details pertinent to any contact(s) made about the household.  The real-time transmission via cellular or wi-fi assists field managers in efforts to improve accountability, operational efficiencies and data validation.

The NHANES is a program of studies designed to assess the health and nutritional status of adults and children in the United States. The survey is unique in that it combines interviews and physical examinations.   The NHANES program began in the early 1960s and has been conducted as a series of surveys focusing on different population groups or health topics. In 1999, the survey became a continuous program (FULLY AUTOMATED THANKS TO THE WESTAT/GUNNISON TEAM) that has a changing focus on a variety of health and nutrition measurements to meet emerging needs. The survey examines a nationally representative sample of about 5,000 persons each year. These persons are located in counties across the country, 15 of which are visited each year.
