Pilot study of methods for assessing unmet secondary health care need in New Zealand.

Abstract

Using the Electoral Rolls to identify respondents is problematic. For a national survey, random population sampling by address, similar to the method employed for the New Zealand Health Survey, but giving respondents a choice between face-to-face and phone interviews, is proposed. Asking GPs to record data on unmet need for secondary care was not successful. Our pilot study suggests there is sufficient unmet secondary healthcare need in New Zealand to merit a national survey.
