We like to think that hospital staff will ensure their patients can stay well. Unfortunately staff do not have the right tools, and 1/2 of hospitalised tamariki Maori aged 0-4 are readmitted within months of going home. This led us to develop the Harti Hauora Tamariki tool, which we modeled on a whanau ora approach. The tool is a set of health screening questions. It was gifted the name Harti Hauora Tamariki and piloted in 2015. Resources were developed by a Maori artist and the tool is still in use at Waikato Hospital. A review found that use of the tool increased screening documentation dramatically, (from almost 0 for many measures). Using Maori health research processes, we will show the effect of follow up actions from Harti Hauora Tamariki screening and effects on child health outcomes, including readmission rates and whanau satisfaction with care.
