[Analysis of Treatment Figures in the Munich Emergency Rooms 2013-2014]

Medical care provided at the hospital emergency rooms in Germany has hardly been explored. On the occasion of restructuring the Municipal Hospital, the Munich City Council initiated the "Round Table Emergency Care" in order to determine reference figures for capacity planning. The present study was designed to analyze treatment data from 14 emergency departments which mainly carry the city's hospital emergency service. For inpatient cases, data were used in accordance with §21 Hospital Charges Act, for outpatient cases - as far as available - similar data were used, anonymized and combined with data from prehospital emergency medical services (EMS). In order to describe the domains treatment urgency, diagnostic/therapeutic effort and bed requirements, data were categorized in a 4-stage system. Over 12 months, 524,716 treatment cases were recorded: 34% were admitted to hospital, 80% came without EMS. One in 7 patients who independently went to an emergency room needed a bed in the intensive care or intermediate care unit (ICU/IMC). There were 64 cases per day and per 100,000 inhabitants requiring 7 ICU/IMC and 15 regular ward beds. Most cases (66%) were treated as outpatients and presented to the hospital's emergency department at times when facilities of the ambulatory care system would have been available. Urgency of these cases was usually low (50.9%), but effort was often high, due to diagnostics and surgical procedures. This study offers fundamental knowledge for planning emergency care. A large proportion of the presentations, especially those with injuries and those with diagnosis that require a more differentiated work-up, seem to be medically justified, which is why appropriate capacities have to be planned in. The study also shows that capacity planning on the basis of EMS cases alone is an inappropriate, one-sided approach.
