To find published data on patient satisfaction in emergency medicine, a systematic review was conducted. Both articles that identified the variables impacting emergency department patients' overall satisfaction and those that assessed a particular intervention were included in the review process. In some trials, but not all, the patient's race and age had an impact on their satisfaction. Satisfaction and triage category were highly connected, but waiting time was also a factor. The three service factors that were most commonly mentioned were perceived waiting times, interpersonal skills and staff attitudes, and informational and explanatory efforts. There were found to be seven controlled intervention studies. These claimed that better ED arrival information and training programmes intended to enhance staff attitudes and communication could increase patient satisfaction. The impact of cutting down on perceived waiting times was not particularly examined in any of the intervention studies. The development of staff interpersonal and attitudinal skills, an increase in the amount of information offered, and a decrease in perceived waiting times will all be crucial treatments to boost patient satisfaction. Future studies should examine particular interventions using a combination of quantitative and qualitative methodologies.
