[Hybrid operating rooms versus conventional operating rooms : Economic comparisons in vascular surgery using the example of endovascular aneurysm repair]. / Hybridoperationssaal vs. konventioneller Operationssaal : Betriebswirtschaftliche Gegenüberstellung in der Gefäßchirurgie am Beispiel der endovaskulären Aneurysmachirurgie.

BACKGROUND: With changing treatment modalities in vascular surgery towards incorporating more endovascular solutions, increased numbers of hybrid operating theatres are being introduced to meet the sterility and imaging quality requirements. These cost-intensive acquisitions however have never been evaluated from an economic perspective. In this study we evaluated cost-relevant parameters before and after the introduction of a hybrid operating room using the example of endovascular aneurysm repair (EVAR) performed in patients with abdominal aortic aneurysms (AAA). METHODS: Retrospective analysis of prospectively collected data. The 4­year period before the introduction of a hybrid operating room were compared with the 4­year period following introduction. Between 2007 and 2010, 97 EVAR procedures were performed before the implementation of a hybrid operating room and 50 EVAR procedures were performed with a hybrid operating room (2012-2015). We evaluated process cost-relevant parameters (operating time) and diagnosis-related group (DRG) parameters (case load, case mix, case mix index). RESULTS: The operating time was significantly reduced on average by 23.5 min (120 min [102-140] vs. 96.5 min [90-120]; p < 0.0001) with a hybrid operating room. This led to a reduction in costs of 276.17 EUR for an EVAR procedure. The case load of EVAR increased from 308 cases from 2007-2010 to 380 cases from 2012-2015 . The associated case mix also increased from 1580 to 1986 points. The total number of case mix points of all managed operative interventions in the operating theatre before and after conversion to a hybrid operating room grew significantly by 17.33% from 8420 to 9880 (p < 0.03) in the compared time periods. CONCLUSION: With detailed, demand-oriented planning, a hybrid operating room can have a favourable economic effect due to a reduction of operating time and the overall lowering of process costs. Thus a refinancing in the long-term is feasible. In addition, this can lead to an increase in the total number and complexity of endovascular procedures.

[Interhospital transfer of severely injured patients in Germany. Evaluation of the DGU trauma register]. / Verlegungsrealität schwerverletzter Patienten in Deutschland. Eine Auswertung im TraumaRegister DGU.

BACKGROUND: The TraumaNetzwerk(D) DGU was founded 3 years ago and since then the majority of trauma centers have been registered and organized into regional trauma network services (TNW). Within these networks assessment criteria for transferring patients to higher level hospitals are defined. The purpose of this study was to evaluate the incidence, causes, implications and quality of care for patients with major trauma who were transferred for definitive treatment before implementation of the TraumaNetzwerk(D) DGU in Germany. PATIENT AND METHODS: The data of 19,035 patients listed in the German Trauma Register of the German Society for Trauma Surgery (DGU, 2002-2007) were analyzed. Patients with an injury severity score (ISS) >9 and a blood pressure documented on admission were included into the study. Data were allocated according to patients where therapy was performed completely in the primary hospital of admission (group I; n=16,033; 84.2%) and patients transferred after primary care from one hospital to another centre for definitive care (group II; n=3,002; 15.8%). Comparative parameters were the pattern and severity of injury, physiological state on admission and clinical outcome. RESULTS: Mean ISS and percentage of patients with an ISS ≥25 did not differ significantly between groups. Of the patients who were transferred to a higher level trauma centre (group II) 20.7% needed catecholamines on admission, 10.1% were in shock (blood pressure <90 mmHg) and 2.5% of the patients underwent resuscitation in the emergency department. Patients of group II had a considerably longer hospital stay (31.2±35.5 days) than patients of group I (24.8±27.1 days). Furthermore, treatment costs were significantly higher for group II (I: EUR 23,870; II: EUR 26,054). CONCLUSIONS: A relevant percentage of patients transferred from one hospital to another were hemodynamically and clinically unstable. To what extent the quality of patient transfer and therefore major trauma care is improved by the implementation of regional trauma networks in Germany remains to be seen over the next years.

Assessment of patients' satisfaction in carotid surgery under local anaesthesia by psychometrical testing--a prospective cohort study.

METHODS: Between July 2008 and December 2008 102 consecutive patients undergoing CEA under local anaesthesia (LA) were prospectively evaluated. All patients were psychometrically assessed by the Hospital Anxiety and Depression Scale (HADS), the EuroQol and the Heidelberg peri-anaesthetic questionnaire (HPQ). Furthermore technical issues of cervical plexus block were assessed. RESULTS: Multivariate analysis with an HPQ sum-score of 98 points as a cut-off level for reduced patients' satisfaction demonstrated that HADS-D scores of >9 (OR: 7.228; p = 0.003), insufficient intra-operative pain control (OR: 3.264; p = 0.0322) and complications due to plexus anaesthesia (OR: 3.794; p = 0.0370) were associated with a low patients' satisfaction in carotid surgery under LA. CONCLUSION: The efficacy of the plexus blockade in terms of pain control and side effects affects patients' satisfaction in carotid surgery under LA. When choosing LA for patients undergoing carotid endarterectomy altered states of anxiety and mood reduce satisfaction in carotid surgery under LA and might compromise patients' suitability for LA.

[Early interdisciplinary geriatric rehabilitation after hip fracture : Effective concept or just transfer of costs?]. / Die geriatrische Frührehabilitation nach hüftgelenknahem Oberschenkelbruch: Nachhaltiges Konzept oder lediglich Kostenverschiebung?

BACKGROUND: Modern strategies for postoperative care of patients with hip fractures include early discharge from the acute care hospital to inpatient interdisciplinary rehabilitation facilities. Whether these programs are effective for the patients and improve their long-term outcomes or if they simply transfer costs, with a reduction of the inpatient days in the acute care hospital, is currently under discussion. PATIENTS AND METHODS: This prospective study included 282 patients with hip fracture admitted to our trauma center were included into the prospective study. The mean patient age was 86+/-8 (65-110) years. All patients were treated operatively. After a mean of 12+/-9 days, the patients underwent inpatient interdisciplinary geriatric rehabilitation for a mean of 27+/-13 (4-103) days. The primary outcome measure was their activities of daily living (Barthel index) before, at the end of rehabilitation, and 1 year after trauma. In addition, patient-related variables were correlated with the Barthel index. RESULTS: With discharge from the acute care hospital, the Barthel index was 42+/-20 points and it increased during rehabilitation to 65+/-26 points. One year later the Barthel index was 67+/-28 points. Ninety percent of patients improved their Barthel index during rehabilitation. Within 1 year, 40% of patients deteriorated in their activities of daily living. Fifty one percent of patients were reintegrated back to their homes. Patients who lived at home before trauma and were reintegrated back to their homes had a significant higher Barthel index (75+/-24) 1 year after trauma than patients who were living in a nursing care facility before the trauma (Barthel index 52+/-27). The variables of age, level of cognition, and type of fracture had no influence on the long-term outcome. An extension of rehabilitation above the mean time period did not improve the sustainable clinical outcome. CONCLUSION: Postoperative inpatient rehabilitation programs enhance short-term activities of daily living. In particular, patients who lived at home before the trauma and were reintegrated back home benefited in perpetuity from geriatric rehabilitation. A policy for early discharge to geriatric rehabilitation is associated with extension of overall hospital stay. This association along with the related increased health care costs should be weighed against the sociofunctional effectiveness of these programs.

Energy intake during economic crisis depends on initial wealth and access to rice fields: the case of pregnant Indonesian women.

Starting in August 1997, Indonesia experienced a radical and rapid deterioration in its economy. Between 1996 and 1998, dietary intake during the second trimester was measured in 450 pregnant women in Purworejo, Central Java, Indonesia. Using six 24 h recalls we describe the consequences of the economic crisis on the energy intake of pregnant Indonesian women. Depending on the date of data collection, women were grouped into 'before crisis', 'transition' and 'during crisis'. Mean energy intake among groups was compared using ANOVA and Student's t-test. All groups of pregnant women already had a mean energy intake before the emerging crisis that was lower than the Indonesian recommended dietary allowances (RDA). Nevertheless, energy intake differed significantly among women with different education levels (P = 0.00) and from different socio-economic groups (P = 0.00). 'During transition', a significant decrease in energy intake was experienced by urban poor women (P = 0.01). Poor women with access to rice fields had a higher rice consumption than other groups throughout the period. Our results most likely reflect the effect of higher rice price on income and welfare. 'During crisis', energy intake improved among vulnerable groups, perhaps reflecting government intervention.

Coil occlusion versus conventional surgical closure of patent ductus arteriosus.

This retrospective cohort study evaluated the clinical outcome and cost-effectiveness of 2 treatment strategies for children with an isolated restrictive patent ductus arteriosus. Results indicate a superior cost-effectiveness of transcatheter coil occlusion compared with conventional surgery for these patients.
