The population of registered nurses and midwives in
Queensland (Australia) hospitals was accessed through the
Queensland Nurses’ Union (QNU) database. There are
approximately 67,000 nurses and midwives registered in
Queensland. Of these 49,806 are QNU members, of whom
approximately 70% receive an electronic newsletter. The
QNU agreed to pass on the survey invitation and link to
these members via the monthly electronic newsletter for
two consecutive months.
