title: [Retrospective Analysis of Diabetics with Regard to Treatment Duration and Costs].
abstract: Background:The increasing incidence of diabetes mellitus is also reflected in the patient population of a trauma and orthopaedic centre. Diabetics also exhibit more comorbidities than non-diabetics. In addition to surgical problems in these patients, hospitalisation is often accompanied by complications, which can prolong treatment and increase costs. The aim of this retrospective study is to analyse hospitalisation of diabetics compared to non-diabetics, as well as differences in treatment costs, depending on associated age and comorbidities.Patients/Material and Methods:17,185 patients were treated at a transregional trauma and orthopaedic centre and were included in this retrospective analysis between 2012 and 2015. Comorbidities and hospitalisation of diabetics and non-diabetics were recorded. All costs charged by DRG were evaluated to calculate the cost per day and per patient, on the basis of the specific case rate. In this calculation, patient-related case rates were divided by the average residence time and the means of the calculated daily rates were calculated. Inclusion criteria were treatment within the various departments and a minimum hospitalisation of one day. Statistical analysis was performed with the SPSS program (version 22.0, SPSS Inc., Chicago, USA).Results:In comparison to non-diabetics (ND), diabetics (D) exhibited significantly more comorbidities, including: obesity, arterial hypertension, coronary heart disease, myocardial infarction (in the history), peripheral arterial disease, chronic kidney disease and hyperlipidaemia. Pneumonia in hospital was considerably commoner in diabetics (2.45 % [D] vs. 1.02 % [ND], p < 0.001). Time in hospital was significantly longer in diabetics (endoprosthetics 13.52 days [D] vs. 12.54 days [ND], p < 0.001; septic surgery 18.62 days [D] vs. 16.31 days [ND], p = 0.007; traumatology 9.82 days [D] vs. 7.07 days [ND], p < 0.001). For patients aged under 60 years, time in hospital was significantly longer for diabetics than for non-diabetics (9.98 days [D] vs. 6.43 days [ND] p < 0.001). Because of the longer time in hospital, treatment costs were higher by € 1,932,929.42 during the investigated time period.Conclusion:Because of their comorbidities, diabetics need to be categorised at an early stage as high-risk patients in traumatological and orthopaedic departments. Hospitalisation and the associated increased treatment costs, as well as postoperative complications, could be minimised in patients with diabetes by implementing an interdisciplinary treatment concept.
