[Admission diagnosis contusion: etiology, epidemiology and cost-causing factors].

BACKGROUND

The admission of patients with minor injuries, such as contusions is a regular practice in acute care hospitals. The pathophysiological changes resulting from the accident are seldom the primary reason for hospitalization. The aim of this retrospective monocentric study was therefore to examine the etiology as well as the cost-causing factors and refinancing on admission.

METHODS

Patients were identified due to a retrospective query in the hospital information system (HIS) according to the ICD-10 German modification codes at discharge. A total of 117 patients were enrolled over a period of 2 years. The classification was carried out according to the accident mechanism and the division into age groups. In addition, the cost calculation was based on department and clinic-specific daily rates.

RESULTS

In terms of etiology low impact falls in the domestic environment were the most common cause (48.7%), followed by high-energy trauma (22.8%). Within the group with domestic falls, the mean age was 77.8 years. This group also showed the longest length of stay (LOS) with 5.2 days. As part of the calculated costs, the group of domestic falls showed the highest costs of 2596.24 € with an average DRG cost revenue of 1464.51 €.

DISCUSSION

The evaluation of the clinic internal data confirmed the subjective perception that the majority of patients admitted with the diagnosis of contusions came from the age group >65 years. Admission is primarily based on the increasing comorbidities and to avert secondary diseases and the consequences of immobilization. It could also be shown that the resulting costs are relevant to health economics and that the treatment does not appear to cover the costs.
