Health Care for Inpatients with a Proximal Humeral Fracture - an Analysis of Health Insurance Data. / Versorgungsrealität stationär behandelter Patienten mit proximaler Humerusfraktur ­ Eine Analyse auf Basis von GKV-Daten.

The proximal humeral fracture is one of the most common fractures in the elderly. While epidemiological factors have been well studied, the influence of a proximal humeral fracture on morbidity, mortality and associated costs has not yet been adequately analysed.On a basis of 4.1 million insurance holders of the German public health insurance (GKV), patients with (study population, SP) and without (comparison group, VG) a proximal humeral fracture (pHF) were compared with regard to comorbidity, rehospitalisation, mortality, drug and aid needs as well as number of physician contacts. Study period was between 2012 and 2016.6068 patients of the SP met the inclusion and exclusion criteria (age 69.4 ± 14.3 years; male : female = 28.2% : 71.8%). 4781 patients (78.8%) received surgical, 1287 patients (21.2%) conservative treatment of the pHF. Rehospitalisations and visits to the general practitioner occurred more frequently in the SP vs. VG (p < 0.01). Contacts with specialists after pHF varied according to specialty, as did newly occurring diseases. Typical specialities for preventive examinations were significantly less common (gynaecology p < 0.01, pathology p < 0.01, dermatology p < 0.01). According to pHF, the costs of SP for drugs (2490.76 ± 1395.51 € vs. 2167.86 ± 1314.43 €; p = 0.04), medical therapies (867.01 ± 238.67 € vs. 393.26 ± 217.55 €; p < 0.01) and aids (821.02 ± 415.73 € vs. 513.52 ± 368.76 €; p < 0.01) were significantly above the VG. The two-year survival after pHF is lower in the SP than in the VG (p < 0.01).The results show increased morbidity and mortality as well as medical costs after a proximal humeral fracture. Preventive examinations and treatments are rarer. In the future, care concepts for patients with proximal humeral fractures should not only be optimised with regard to functional scores and reduced complication rates, but also with regard to quality of life and preservation of general health.

The Relation of Surgical Procedures and Diagnosis Groups to Unplanned Readmission in Spinal Neurosurgery: A Retrospective Single Center Study.

BACKGROUND: Unplanned readmission has gained increasing interest as a quality marker for inpatient care, as it is associated with patient mortality and higher economic costs. Spinal neurosurgery is characterized by a lack of epidemiologic readmission data. The aim of this study was to identify causes and predictors for unplanned readmissions related to index diagnoses and surgical procedures. METHODS: In this study, from 2015 to 2017, spinal neurosurgical procedures were recorded for surgical and non-surgical treated patients. The main reasons for an unplanned readmission within 30 days following discharge were identified. Multivariate logarithmic regression revealed predictors of unplanned readmission. RESULTS: A total of 1172 patient records were examined, of which 4.27% disclosed unplanned readmissions. Among the surgical patients, the readmission rate was 4.06%, mainly attributable to surgical site infections, while it was 5.06% for the non-surgical patients, attributable to uncontrolled pain. A night-time surgery presented as the independent predictive factor. CONCLUSION: In the heterogeneous group of spinal neurosurgical patients, stratification into diagnostic groups is necessary for statistical analysis. Degenerative lumbar spinal stenosis and spinal abscesses are mainly affected by unplanned readmission. The surgical procedure dorsal root ganglion stimulation is an independent predictor of unplanned re-hospitalizations, as is the timing of surgery.

[Cross-sectional diagnostic imaging in the InEK benchmark : An opportunity for radiology]. / Schnittbilddiagnostik im InEK­Benchmark : Eine Chance für die Radiologie.

BACKGROUND: Based on the lump sum system which is calculated by the InEK (Institut für das Entgeltsystem im Krankenhaus), it is possible to compare one hospital's own performance data with all hospitals in Germany billing according to the Diagnosis-Related Group (DRG). The aim of this article is to investigate exceeding or undercutting of computed tomography (CT) or magnetic resonance imaging (MRI) in comparison to the calculations made by the InEK to reveal potential for improvement. METHODS: InEK calculation data for 2021 were used to form comparative ratios for CT and MRI diagnostics at the DRG level. Data from a university hospital was compared at the hospital, departments, DRG and main diagnosis levels. RESULTS: At the hospital level, there were 1025 more MRIs and 371 more CTs compared to InEK. Analysis by department showed, e.g., in neurology, 489 more MRIs and 620 fewer CTs. The benchmark of the DRGs showed in particular that DRG B70B was the driver of deviations in both diagnostic modalities (MRI [Formula: see text] CT [Formula: see text]). The identified deviations can be further analysed at the main diagnosis level. CONCLUSION: Awareness of above-average use of cross-sectional imaging diagnostics can provide impetus for further development of clinical pathways of a hospital. The methodology of the InEK benchmark is applicable to every hospital and is able to identify processes with potential for improvement. The review of influencing factors as well as the evaluation by clinicians and economists are prerequisite for acceptance and success of the measures generated from the benchmark.

[Potential of inpatient cases of a university hospital for orthopedics and trauma surgery for outpatient care]. / Ambulantisierungspotenzial stationärer Fälle einer universitären Klinik für Orthopädie und Unfallchirurgie.

BACKGROUND: The act of the Medical Service of the Health Funds (MDK) is intended to shift health services previously provided in inpatient care to the outpatient care sector in accordance with § 115b SGB V. The aim of this study was the investigation of potential groups of inpatient cases of a university hospital for trauma surgery and orthopedics, which might be at risk for transfer to surgical outpatient treatment. METHODS: Data collection using SAP Data Warehouse included all inpatient cases 2017-2019, with subgroup analysis of economic parameters of three risk groups (RG): 1) primary misallocation, 2) procedures of AOP categories 1 and/or 2 and 3) elective 1­day cases. Furthermore, an analysis of epidemiological parameters and an economic evaluation were performed. RESULTS: Primary misallocations related to 245 cases, RG 2 had 764 cases and RG 3 had 891 cases. The average age was 45.5 ± 17.7 years and in 90% there were no relevant comorbidities (PCCL 0). The majority of cases were assigned to DRG I23B and I21Z (removal of osteosynthesis material, 15-23%), followed by open or arthroscopic surgery of the extremities (DRG I32F, I32G, I24Z, I18B, 6-9%). In cases of a statutory shift of inpatient to outpatient surgical procedures, the potential loss of revenue in 2017 was €â€¯1,049,207, in 2018 €â€¯1,076,727 and in 2019 €â€¯923,163. CONCLUSION: Individual groups have an increased potential in certain DRGs for a shift from inpatient to outpatient surgical procedures and are at risk for relevant revenue reductions in the course of further expansion of outpatient care. Proactive patient management in terms of outpatient versus inpatient treatment and special management of staff and spatial resources are necessary to anticipate potential downstream revenue cuts.

[Is polytrauma treatment in deficit in the aG-DRG system?] / Ist die Polytraumaversorgung im aG-DRG-System defizitär?

BACKGROUND: The interdisciplinary care of severely injured patients is staff and resource intensive. Since the introduction of the G­DRG system in Germany in 2003, most studies have identified a financial deficit in the care of severely injured patients. The aim of this study was to analyze the effects of the new aG-DRG system introduced in 2020 on cost recovery in the treatment of severely injured patients. For the first time, the costs for organization, certification and documentation as well as the costs for non-seriously injured shock room patients were included. METHODS: All patients who were treated in the surgical shock room of the emergency department of the Leipzig University Hospital in 2017 were included. For the analysis, the cost model according to Pape et al. was extended by the module organization, documentation and certification and for the first time the costs for overtriaged patients were considered. A cost calculation was performed for the years 2017-2020 as well a comparison with the respective earnings. RESULTS: A total of 834 patients were treated in the shock room and 258 severely injured patients were divided into 3 groups: ISS 9-15 + ICU (n 72; ∅ ISS 11.9; costs per patient 14,715 €),ISS ≥ 16 (n 186; ∅ ISS 27.7; costs per patient 30,718 €) and DRG polytrauma (n 59; ∅ ISS 32.4; costs per patient 26,102 €). CONCLUSION: Polytrauma care under the aG-DRG 2020 is in deficit. Overall, in 2020 a deficit of 5858 € per severely injured patient resulted.

Central COVID-19 Coordination Centers in Germany: Description, Economic Evaluation, and Systematic Review.

BACKGROUND: During the COVID-19 pandemic, Central COVID-19 Coordination Centers (CCCCs) have been established at several hospitals across Germany with the intention to assist local health care professionals in efficiently referring patients with suspected or confirmed SARS-CoV-2 infection to regional hospitals and therefore to prevent the collapse of local health system structures. In addition, these centers coordinate interhospital transfers of patients with COVID-19 and provide or arrange specialized telemedical consultations. OBJECTIVE: This study describes the establishment and management of a CCCC at a German university hospital. METHODS: We performed economic analyses (cost, cost-effectiveness, use, and utility) according to the CHEERS (Consolidated Health Economic Evaluation Reporting Standards) criteria. Additionally, we conducted a systematic review to identify publications on similar institutions worldwide. The 2 months with the highest local incidence of COVID-19 cases (December 2020 and January 2021) were considered. RESULTS: During this time, 17.3 requests per day were made to the CCCC regarding admission or transfer of patients with COVID-19. The majority of requests were made by emergency medical services (601/1068, 56.3%), patients with an average age of 71.8 (SD 17.2) years were involved, and for 737 of 1068 cases (69%), SARS-CoV-2 had already been detected by a positive polymerase chain reaction test. In 59.8% (639/1068) of the concerned patients, further treatment by a general practitioner or outpatient presentation in a hospital could be initiated after appropriate advice, 27.2% (291/1068) of patients were admitted to normal wards, and 12.9% (138/1068) were directly transmitted to an intensive care unit. The operating costs of the CCCC amounted to more than €52,000 (US $60,031) per month. Of the 334 patients with detected SARS-CoV-2 who were referred via EMS or outpatient physicians, 302 (90.4%) were triaged and announced in advance by the CCCC. No other published economic analysis of COVID-19 coordination or management institutions at hospitals could be found. CONCLUSIONS: Despite the high cost of the CCCC, we were able to show that it is a beneficial concept to both the providing hospital and the public health system. However, the most important benefits of the CCCC are that it prevents hospitals from being overrun by patients and that it avoids situations in which physicians must weigh one patient's life against another's.

Causes and Predictors of Unplanned Readmission in Cranial Neurosurgery.

OBJECTIVE: A better understanding of the risks and reasons for unplanned readmission is an essential component in reducing costs in the health care system and in optimizing patient safety and satisfaction. The reasons for unplanned readmission vary between different disciplines and procedures. The aim of this study was to identify reasons for readmission in view of different diagnoses in cranial neurosurgery. METHODS: In this single-center retrospective study, adult patients after neurosurgical treatment were analyzed and grouped according to the indication based on International Classification of Diseases and Related Health Problems, Tenth Revision, German Modification diagnosis codes. The main outcome measure was unplanned readmission within 30 days of discharge. Further logistic regression models were performed to identify factors associated with unplanned rehospitalization. RESULTS: Of the 2474 patients analyzed, 183 underwent unplanned rehospitalization. Readmission rates differed between the diagnosis groups, with 9.19% in neoplasm, 8.26% in hydrocephalus, 5.76% in vascular, 6.13% after trauma, and 8.05% in the functional group. Several causes were considered to be preventable, such as wound healing disorders, seizures, or social reasons. Younger age, length of first stay, surgical treatment, and side diagnoses were predictors for unplanned readmission. Diagnoses with an increased risk of readmission were glioblastoma, traumatic subdural hematoma, or chronic subdural hematoma. CONCLUSIONS: Reasons and predictors for an unplanned readmission differ considerably among the index diagnosis groups. In addition to well-known reasons for readmission, we identified social indication, meaning a lack of home care, which is particularly prevalent in oncologic and elderly patients. A transitional care program could benefit these vulnerable patients.

[How severe is the effect of the coronavirus pandemic on the department of surgery of a university hospital? : An analysis of the first 7 weeks]. / Wie stark trifft die Corona-Pandemie die chirurgische Klinik eines universitären Maximalversorgers? : Eine Analyse der ersten 7 Wochen.

BACKGROUND: The corona pandemic poses enormous financial challenges for hospitals. Using the example of a clinic for visceral, transplantation, thorax and vascular surgery (VTTG), the performance development of inpatient care in the first 7 weeks in comparison to the previous year as well as an evaluation of the compensation measures laid down by law were evaluated. METHODOLOGY: Based on the performance figures, a comparison was made between the period from 16 March to 3 May 2019 and the same period in 2020. Changes in the number of cases, case mix, case mix index and day mix index as well as the bed occupancy days were recorded. The monetary measures from the COVID-19 Hospital Relief Act were applied to these changes and the adequacy was evaluated. RESULTS: Compared to the previous year there was a decrease in inpatient admissions of 120 patients during the observation period. As a result there was a decrease of 370 points in case mix and 1433 days of occupancy. For the whole VTTG this resulted in a decrease in revenue of approximately 0.8 million €, which was completely compensated by the flat rate payment for empty beds. The individual areas of the VTTG showed a heterogeneous picture in relation to the compensation for the loss of revenue. Elective units in particular showed a shortfall up to 128,163 € with respect to inpatient treatment for 7 weeks. CONCLUSION: The measures taken by the Government are an important support for the economic security of German hospitals. The lack of differentiation of measures by specialty leads to a heterogeneous picture in compensation for VTTG revenues and has to be understood as an alarm signal especially for elective surgical healthcare.

Early unplanned readmission of neurosurgical patients after treatment of intracranial lesions: a comparison between surgical and non-surgical intervention group.

BACKGROUND: Recent health care policy making has highlighted the necessity for understanding factors that influence readmission. To elucidate the rate, reason, and predictors of readmissions in neurosurgical patients, we analyzed unscheduled readmissions to our neurosurgical department after treatment for cranial or cerebral lesions. METHODS: From 2015 to 2017, all adult patients who had been discharged from our Department of Neurosurgery and were readmitted within 30 days were included into the study cohort. The patients were divided into a surgical and a non-surgical group. The main outcome measure was unplanned inpatient admission within 30 days of discharge. RESULTS: During the observation period, 183 (7.4%) of 2486 patients had to be readmitted unexpectedly within 30 days after discharge. The main readmission causes were surgical site infection (34.4 %) and seizure (16.4%) in the surgical group, compared to natural progression of the original diagnosis (38.2%) in the non-surgical group. Most important predictors for an unplanned readmission were younger age, presence of malignoma (OR: 2.44), and presence of cardiovascular side diagnoses in the surgical group. In the non-surgical group, predictors were length of stay (OR: 1.07) and the need for intensive care (OR: 5.79). CONCLUSIONS: We demonstrated that reasons for readmission vary between operated and non-operated patients and are preventable in large numbers. In addition, we identified treatment-related partly modifiable factors as predictors of unplanned readmission in the non-surgical group, while unmodifiable patient-related factors predominated in the surgical group. Further patient-related risk adjustment models are needed to establish an individualized preventive strategy in order to reduce unplanned readmissions.

[How badly is the coronavirus pandemic affecting orthopaedic and trauma surgery clinics? : An analysis of the first 5 weeks]. / Wie stark trifft die Corona-Pandemie die Kliniken für Orthopädie und Unfallchirurgie? : Eine Analyse der ersten 5 Wochen.

BACKGROUND: The corona pandemic poses enormous financial challenges for hospitals. Using the example of a clinic for orthopaedics and trauma surgery, the performance development of the first 5 weeks in comparison to last year and an evaluation of the compensation measures laid down by law will be evaluated. METHODOLOGY: Based on the performance figures, a comparison is made between the period 16.03 to 17.04.2019 and the same period in 2020. Changes in the number of cases, case mix, case-mix index and day-mix index, as well as the occupancy days are recorded. The monetary measures from the COVID-19 Hospital Relief Act are applied to these changes, and the adequacy is evaluated. RESULTS: Compared to last year, there was a decrease in inpatient admissions of n = 307 patients in the observation period. As a result, there was a decrease of 595 points in case mix and 2320 days of occupancy. This results in a decrease in revenue of approximately EUR 1.9 million. The flat rate for empty beds represents the largest monetary compensation for the loss of revenue. It amounts to approximately EUR 1.3 million. Taking into account further support and an adjustment for variable costs, a deficit of EUR 382,069 remains for 5 weeks. DISCUSSION: The measures taken by the Government are an important pillar for the economic security of German hospitals. The lack of differentiation of measures by specialty leads to insufficient compensation for orthopaedics and trauma surgery.

Validation of a new method for evaluation of syndesmotic injuries of the ankle.

PURPOSE: To define a new parameter in CT that could make imaging of the contralateral ankle dispensable evaluating the position of the fibula after syndesmotic injury. METHODS: Thirty bilateral CTs of 30 patients were included. Five parameters were defined in axial CT for the injured (_inju) and uninjured (_unin) ankle. Reproducibility was examined for inter-observer and intra-observer reliability. Comparisons for all parameters were performed between the CT scans of both ankles. RESULTS: All measurements had a high agreement for the inter-observer and intra-observer correlation coefficients. A large interindividual variance could be found between all parameters. If the difference of the anterior tibiofibular distance antTFD_unin and antTFD_inju was less than 2 mm, there was a strong significant pairwise correlation between all parameters between both sides. CONCLUSION: Bilateral CT is still to be recommended, as it is the only way to exactly assess anterior posterior reduction of the fibula.

[Cost-Effectiveness and Cost-Utility Analyses of Antireflux Medicine]. / Kosten-Effektivitäts- und Kosten-Nutzwert-Analysen der Antirefluxmedizin.

INTRODUCTION: Laparoscopic antireflux surgery and medical therapy with proton pump inhibitors are gold standards of gastroesophageal reflux treatment. On account of limited resources and increasing healthcare needs and costs, in this analysis, not only optimal medical results, but also superiority in health economics of these 2 methods are evaluated. METHODS: We performed an electronic literature survey in MEDLINE, PubMed, Cochrane Library, ISRCTN (International Standard Randomization Controlled Trial Number) as well as in the NHS Economic Evaluation Database, including studies published until 1/2017. Only studies considering the effect size of QALY (Quality-Adjusted Life Years) (with respect to different quality of life-scores) as primary outcome comparing laparoscopic fundoplication and medical therapy were included. Criteria of comparison were ICER (Incremental Cost-Effectiveness Ratio) and ICUR (Incremental Cost-Utility Ratio). Superiority of the respective treatment option for each publication was worked out. RESULTS: In total, 18 comparative studies were identified in the current literature with respect to above-mentioned search terms, qualifying for the defined inclusion criteria. Six studies were finally selected for analyses. Out of 6 publications, 3 showed superiority of laparoscopic fundoplication over long-term medical management based on current cost-effectiveness data. Limitations were related to different time intervals, levels of evidence of studies and underlying resources/costs of analyses, healthcare systems and applied quality of life instruments. CONCLUSION: Future prospective, randomized trials should examine this comparison in greater detail. Additionally, there is a large potential for further research in the health economics assessment of early diagnosis and prevention measures of reflux disease and Barrett's esophagus/carcinoma.

Endoscopic Removal of a Scapular Osteophyte Using Scapulothoracic Arthroscopy.

This article describes the removal of a scapular osteophyte from the subscapular space by scapulothoracic arthroscopy. The endoscopic technique allows a gentle approach to the subscapular space without causing a large amount of surgical trauma and therefore leads to good cosmetic and functional results.

Snapping knee syndrome caused by semitendinosus and semimembranosus tendons. A case report.

We report the case of a 24-year-old female triathlon athlete with a snapping syndrome of both the distal semimembranosus and the semitendinosus tendon which has not been described so far. The semitendinosus tendon was harvested whereupon snapping has diminished. Tenoscopy and digital palpation showed the semimembranosus tendon to cause the snapping, as well. A careful step-by-step release of the anterior insertion of the tendon was performed with the result of a snapping-free range of motion of the patient's knee.

Arthroscopically guided navigation for repair of acromioclavicular joint dislocations: a safe technique with reduced intraoperative radiation exposure.

BACKGROUND: Accuracy evaluation of navigated image free placement of double cortical fixation buttons for coracoclavicular tunnel position in comparison to conventional drill guide based placement. METHODS: Twenty-six patients with acute acromioclavicular joint instability were included in this non-randomized cohort study. All patients were treated with a Double- TightRope technique. In 13 cases the conventional drill guide based placement was used (group 1). In 13 patients surgery was performed as a navigated procedure with a fluoro-free optoelectronic system (group 2). The number of coracoclavicular drillings per patient (First pass accuracy; FPA (%)) was documented, the subcoracoidal position of the fixation buttons has been evaluated and graded as "intended position achieved (IPA)" or "intended position not achieved (IPnA)". RESULTS: In group 1 drilling had to be repeated in four patients (30.8 %) to achieve proper placement of the subcoracoidal fixation buttons. 100 % first pass accuracy was observed in group 2 (p = 0.03). In group 1, the intended position of the subcoracoid buttons was not achieved (IPnA) in six patients (46.2 %). In group 2 all intended positions were achieved (p = 0.005). CONCLUSION: Arthroscopic controlled fluoro-free navigated coracoclavicular drilling for the repair of acromioclavicular joint dislocation has higher first pass accuracy in comparison to conventional drill guide based placement. Therefore the navigation enables a precise position of the drill holes, may reduce the risk of an iatrogenic coracoid fracture and migration of fixation devices. TRIAL REGISTRATION: Local institutional review board No. 061-14-10032014.

Image-free navigated coracoclavicular drilling for the repair of acromioclavicular joint dislocation: a cadaver study.

BACKGROUND: Reconstruction of the coracoclavicular ligament functions to restore anatomic alignment of the clavicle and may improve biomechanical function and clinical outcomes. Improper placement of the coracoclavicular tunnel may inherently weaken the coracoid. The purpose of this study was to evaluate the feasibility and accuracy of navigated image-free placement of K-wires for coracoclavicular tunnel position in comparison to conventional drill guide-based placement. MATERIALS AND METHODS: Eight human shoulder specimens were assigned for conventional technique with a coracoclavicular guide device (group CP) and the paired contralateral side for the navigated procedure (group NP) with an optoelectronic system with a fluoro-free software module. First-pass accuracy (%) and the K-wire trajectory (lateral-center orientation (LC), center-center (CC) orientation and medial-center orientation (MC) were measured. RESULTS: In all navigated K-wires a 100 % first-pass accuracy was observed. In three of the eight (37.5 %) specimens of the drill guide-based group, drilling had to be repeated. One of them had to be repeated twice, resulting in eight versus twelve drillings for the navigated versus conventional group, respectively (p = 0.021). K-wire trajectory showed an MC orientation in most of the specimen (n = 9, group NP 4, group CP 5). CONCLUSIONS: Image-free navigated coracoclavicular drilling for the repair of acromioclavicular joint dislocation has higher first-pass accuracy in comparison to conventional drill guide-based placement and, therefore, may enable a precise anatomic position of the drill holes and reduce the risk of an iatrogenic coracoid fracture.

Osteoid osteoma of the proximal fibula: an uncommon location with the indication for open surgery.

Purpose. This is a case report of a patient with an osteoid osteoma of the proximal fibula. The objective is to illustrate a rare tumor location that requires open surgery due to closeness of neurological structures. Methods. Clinical and roentgenographic findings, treatment, and histological appearance are presented. Results. Local pain and swelling of the proximal fibula with improvement under salicylates led to the diagnosis of an osteoid osteoma, what was confirmed with an MRI scan. Due to proximity to the common peroneal nerve, we decided for open surgery. During the operation, the nerve was seen to cross the tumor site making it necessary to retract it to expose the entire tumor. Histologically, typical features of osteoid osteoma with a rather well-defined nidus surrounded by sclerotic bone were seen. A complete removal was performed. Conclusion. Osteoid osteomas of the proximal fibula are rare. When planning surgery, the common peroneal nerve must be identified, and its further distal course should be taken into account to avoid iatrogenic damage to the nerve.
