Portable electronic technology increasing effective access to information in local evidence-based planning. The electronic data capture process was developed to support local public health information management in Canada. The process utilizes portable, inexpensive palm-size personal computers and involves three stations: collecting the data, data transfer and analysis. It is the subject of a CIET master’s thesis by Ari Ho-Foster.

New approaches to the traditional questionnaire: The Bhopal Book (designed in the immediate aftermath of the Bhopal disaster) is used for data capture at the household interview. The questionnaire is pasted on the outer edges of the inside covers of an exercise book and the pages are cut or folded in half vertically, with one page per household. This prevents loose pages from getting misplaced and is easier to maintain and preserve. To view an image of the Bhopal Book in use, click here.
