Patient empowerment and visualisation on mobile devices

Abstract

Improved potentiality using multimedia components (audio, video, threedimensional pictures and interactive tools) as well as the growing desire of patients to receive more information leads to a widespread introduction of patient information systems. In co-operation with the "Wissenschaftliches Institut der Praxisärzte", Heidelberg we developed a tool to explain medical facts with twoand three dimensional pictures. In contrast to common web based information systems the tool is used by the physician itself to explain the medical content. The investigation will be carried out on a group of 50 patients from 2 different wards. Participants need a Karnofsky-Index of 70 points minimum. In a randomly process patient will be allocated to either a group which receive standardised information supported by the picture material or just a standardised consent talk. Detailed information is given about the indication, the probable complications and the details of the forthcoming procedures (coronary catheters or endoscopic procedures). The procedure takes place one day after the conversation between the physician and the patient. We conduct a prospective, randomised investigation using a tool called "Dr. Topf's Patienteninformationssystem" which has been designed to supplement the clarification of facts. A sample of 5 pictures maximum is presented on a sub-notebook. The computerised animation is limited to 5 minutes. Participants of the control group are informed with support of the common informative pamphlet only. An analysis of the time required is being performed. Short after the conversation between physician and patient, the patient is asked to personally assess the quality of the consent talk. 3 days later we check the evidence of the visualised approach using a formalised questionnaire (standard of knowledge). 10 multiple-choice questions, been taken from students assessment questionnaire and adapted to patient knowledge level, apply to the contents of the happened conversation.
