Local Gentamicin Fixation with Sprayed Fibrin-An In Vivo Animal Study Reveals New Options to Treat Soft Tissue Infections

For acute and chronic soft tissue infections, radical surgical debridement is required and is considered the gold standard, along with its immediate systemic antibiotic therapy. Treatment with local antibiotics and/or antibiotic-containing materials is commonly used as an additional tool in clinical practice. Spraying with fibrin and antibiotics is a newer technique that has been studied for some antibiotics. However, for gentamicin, data are not yet available on absorption, optimal application, antibiotic fate at the site and transfer of antibiotic into the blood. In an animal study involving 29 Sprague Dawley rats, 116 back wounds were sprayed with gentamicin using either gentamicin alone or one of two possible spray combinations of gentamicin and fibrin. Simultaneous application of gentamicin and fibrin via a spray system to soft tissue wounds resulted in significant antibiotic concentration over a long period of time. The technique is easy and cost-effective. The systemic crossover was significantly minimized in our study, which may have led to fewer side effects in patients. These results could lead to an improvement in local antibiotic therapy.

Cranial CT is a mandatory tool to exclude asymptomatic cerebral hemorrhage in elderly patients on anticoagulation

Background

Traumatic brain injury (TBI) after falls causes death and disability with immense socioeconomic impact through medical and rehabilitation costs in geriatric patients. Diagnosing TBI can be challenging due to the absence of initial clinical symptoms. Misdiagnosis is particularly dangerous in patients on permanent anticoagulation because minimal trauma might result in severe intracranial hemorrhage. The aim of this study is to evaluate the diagnostic necessity of cranial computed tomography (cCT) to rule out intracranial hemorrhage, particularly in the absence of neurologic symptoms in elderly patients on permanent anticoagulation in their premedication.

Patients and methods

Retrospective cohort analysis of elderly trauma patients (≥ 65 years) admitted to the emergency department (ED) of the level-1-trauma center of the University Hospital Frankfurt from 01/2017 to 12/2019. The study included patients who suffered a ground-level fall with suspected TBI and subsequently underwent CT because of preexisting anticoagulation.

Results

A total of 227 patients met the inclusion criteria. In 17 of these patients, cCT showed intracranial hemorrhage, of which 14 were subdural hematomas (SDH). In 8 of the patients with bleeding showed no clinical symptoms, representing 5% (n = 160) of all symptom-free patients. Men and women were equally to suffer a post-traumatic hemorrhage. Patients with intracranial bleeding were hospitalized for 14.5 (±10.4) days. Acetylsalicylic acid (ASA) was the most prescribed anticoagulant in both patient cohorts-with or without intracerebral bleeding (70.6 vs. 77.1%, p = 0.539). Similarly, patients taking new oral anticoagulant (NOAC) (p = 0.748), coumarins, or other platelet inhibitors (p > 0.1) did not show an increased bleeding incidence.

Conclusion

Acetylsalicylic acid and NOAC use are not associated with increased bleeding risk in geriatric trauma patients (≥ 65 years) after fall-related TBI. Even in asymptomatic elderly patients on anticoagulation, intracranial hemorrhage occurs in a relevant proportion after minor trauma to the head. Therefore, cCT is an obligatory tool to rule out cerebral hemorrhage in elderly patients under anticoagulation.

Seizure related injuries - Frequent injury patterns, hospitalization and therapeutic aspects

PURPOSE

Epileptic seizures frequently result in distinct physical injuries, fractures, traumatic brain injuries and minor trauma. The aim of this study was to retrospectively determine the frequent injury patterns due to seizure episode and to analyze consecutive acute medical care.

METHODS

This retrospective mono-center study was conducted at Frankfurt University Hospital, Frankfurt am Main, Germany between January 2007 and December 2017. Epilepsy patients with seizure-related fractures admitted to the emergency department were identified via a retrospective systematic query in the hospital information system using the ICD-10 German modification codes G40.0-G40.9. Patients with an unclear diagnosis of epilepsy were excluded. Sociodemographic as well as disease specific aspects were analyzed. Descriptive and Kruskal-Wallis one-way analysis of variance were used for statistical analysis.

RESULTS

A total number of 62 epilepsy patients were included. The mean age was 58.1 years. Fractures concerned the upper extremity most frequently (43.5%, n = 20), and 70.0% (14/20) were humerus fractures. Admission to intensive care unit for acute trauma care was necessary in 29.0% patients (n = 18), and surgery in 45.2% patients (n = 28). Twenty-five patients (26.6%) showed clinical or radiological signs of traumatic brain injury. Provoking factors were identified in 20 patients (32.3%), i.e., acute withdrawal or excess of alcohol (n = 15), relevant sleep deprivation (n = 2), and intoxication or withdrawal of other illegal drugs or trivial infect (n = 1 for each) and non-compliance with anti-seizure drugs (n = 1). A decreased T-score (-1.04 ± 1.15) and Z-score (-0.84 ± 0.75) compared to healthy subjects were found.

CONCLUSION

Fractures in upper extremities, trunk and craniocerebral trauma occur frequently as seizure-induced injuries. Alcohol excess and withdrawal are important provoking factors and should be targeted with preventive measurements to avoid seizure related injuries and accidents.

Health Economic Challenge: Geriatric Trauma-An Age-Based Observational Analysis of Treatment Costs and Reimbursement Issues

Demographic change is having a major impact on the economic and structural development of the healthcare system. People stay active longer and the number of mild traumatic brain injury [mTBI] in patients ≥ 65 years of age consequently increases. The aim of this comparative analysis is to illustrate the impact of demographic change and the increasing treatment of geriatric trauma patients on the cost structure of the health care system using mTBI as an example diagnosis. Patients and Methods: The 12-month retrospective analysis included 220 in-patients treated with mTBI and remunerated under the German Diagnosis Related Group [G-DRG] B80Z. For comparative analysis, the patient population was divided into two study groups according to age [U65 18−64 years, G65 ≥ 65 years]. For the cost and proceeds calculation, itemized cost reports (personnel, supply, material, and equipment costs, etc.) were created. Results: 163 patients U65 and 57 patients G65 were included. In the G65 group, the most frequent accident mechanism was a fall from a short distance (84.1 vs. U65 36.7%; p = 0.007). For the inpatient admission of G65, the use of anticoagulants (p < 0.001) and comorbidity (p = 0.002) played a primary role, while for younger patients it was more neurological symptoms (p < 0.001) and alcohol (p < 0.001) that led to inpatient monitoring. The mean length of hospitalization of G65 patients was significantly longer than that of younger patients (G65 2.4 ± 1.9 days > U65 1.7 ± 0.8 days; p = 0.007) and radiological examinations (G65 94.7% > U65 23.3%; p = 0.013) were performed more frequently. Comparing analysis of the cost and proceeds of U65 vs. G65 results in a proceeds difference of €51,753.91 per year for the G-DRG B80Z compared to U65. Conclusions: It has been shown that there is a difference in costs and proceeds when comparing younger and older patients, resulting in a reimbursement deficit. In view of the demographic development in Europe, flat-rate remuneration will lead to a considerable discrepancy between DRG reimbursement and the coverage of hospitals’ running costs. Providing health care to an increasingly aging society represents one of the major personnel and financial challenges for the public health system in the coming decades. Further adaptation of the DRG system to the growing costs caused by older patients is imperative.

[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.

[Inpatient treatment costs, cost-driving factors and potential reimbursement problems due to epileptic seizure-related injuries and fractures]

BACKGROUND

The systematic analysis of disease-specific costs is becoming increasingly more relevant in an economically oriented healthcare system. Chronic diseases are of particular interest due to the long duration as well as frequent hospitalization and physician visits. Epilepsy is a frequent neurological disorder affecting all age groups with the clinical hallmark of paroxysmal epileptic seizures, which are often associated with injuries.

OBJECTIVE

The aim of this work was to process the inpatient treatment costs due to seizure-related injuries and fractures. Moreover, relevant cost-causing factors were addressed. Using an alternative calculation of the costs of care, the question of potential reimbursement problems in the current German diagnosis-related groups (G-DRG) system was additionally assessed.

METHODS

For this monocentric retrospective analysis the actual proceeds of 62 inpatients who were treated at the University Hospital Frankfurt between January 2010 and January 2018 for injuries and fractures due to epileptic seizures were used. The analysis of potential cost-causing factors was carried out with respect to relevant sociodemographic and clinical aspects. The alternative calculation of the costs of treatment was carried out using established health economic methods.

RESULTS

The average DRG revenue was 7408€ (±8993€, median 5086€, range 563-44,519€), the average calculated costs were 9423€ (±11,113€, 5626€, range 587-49,830€). A length of stay ≥7 days (p = 0.014) was identified as a significant cost-driving factor. Due to the significant difference (p < 0.001) between revenue and calculated costs, an analysis was made according to factors for potential reimbursement problems, which remained significant for a length of stay of ≥7 days (p = 0.014) and for treatment in the intensive care unit (p = 0.019).

CONCLUSION

The inpatient treatment costs for patients with injuries and fractures due to epileptic seizures are high and therefore relevant from a health economic perspective. In general, reimbursement according to the G‑DRG appears to cover the actual costs, but there may be reimbursement problems for patients with a long period of hospitalization or a stay in an intensive care ward.

[Cost factor "outpatient wound care" in the emergency department : Cost-revenue deficit of outpatient wound treatment in a German university hospital]

BACKGROUND

In addition to highly specialized medicine, the initial treatment of wounds and minor surgical interventions are generally necessary basic services of emergency care in hospitals. The reimbursement of outpatient emergency services for persons with statutory insurance is currently based on the uniform assessment standard (EBM), where the recording of business expenses in the private practice sector serves as the basis for the calculation. Hospitals have considerably higher maintenance costs than medical practices.

OBJECTIVE

In this article the resulting cost-revenue ratio of outpatient wound care in an emergency department is analyzed through the reimbursement according to EBM.

MATERIAL AND METHODS

The data were collected in the emergency surgical department of the University Hospital Frankfurt am Main over 12 months. Included were all patients who received sutured wound care during this period. The costs incurred were compared to the remuneration according to EBM 01210 (or 01212) with the additional flat rate for small surgical procedures EBM 02301.

RESULTS

During the observation period 1548 patients were treated, i.e. 19.52% of all trauma surgery cases. The resulting costs of a standard wound care of 45.40 € are offset by a remuneration of 31.83 €. The calculation of the total revenue shows a deficit amount of 13.57 € per outpatient case, this corresponds to an annual deficit of 21,006.36 €.

CONCLUSION

It could be shown that even without consideration of the relevant holding costs, cost coverage cannot be achieved in any case. The previous reimbursement of outpatient wound care on the basis of the EBM appears to be inadequate. In the future, an adjustment or supplementary remuneration seems to be necessary in order to ensure sufficient quality of care.
