Implementation of a patient blood management monitoring and feedback program significantly reduces transfusions and costs

Patient blood management (PBM) measures have been shown to be effective in reducing transfusions while maintaining patient outcome. The issuance of transfusion guidelines is seen as being key to the success of PBM programs. As the introduction of guidelines alone did not visibly reduce transfusions in our center, a monitoring and feedback program was established. The aim of our study was to show the effectiveness of such measures in reducing transfusions and cost.

Brentuximab as a treatment for CD30+ mycosis fungoides and Sézary syndrome.

IMPORTANCE The prognosis of advanced cutaneous T-cell lymphoma (CTCL), including Sézary syndrome and mycosis fungoides (MF), is poor. So far, no curative option apart from allogeneic stem cell transplantation is available. Large cell transformation often hallmarks cases with a more aggressive clinical course, and large tumor cells may express CD30. Recently, brentuximab vedotin, a conjugate of an anti-CD30 antibody and monomethylauristatin E, which inhibits the polymerization of microtubuli, has produced promising results in phase 2 trials in CD30+ Hodgkin lymphoma and anaplastic large cell lymphoma. OBSERVATIONS We describe 4 patients with advanced CTCL, 3 with MF and 1 with Sézary syndrome, who were treated with brentuximab. All patients had received multiple previous systemic therapies. In 2 cases of MF, a remission enabling subsequent allogeneic stem cell transplantation was achieved. CONCLUSIONS AND RELEVANCE Brentuximab is a well-tolerated, promising new treatment option for advanced CTCL that can be integrated in an allogeneic stem cell transplantation plan by selectively depleting malignant CD30+ cutaneous lymphoma cells.

Young adults with mild traumatic brain injury—the influence of alcohol consumption—a retrospective analysis

PurposeAlcohol abuse has been associated with aggressive behavior and interpersonal violence. Aim of the study was to investigate the role of alcohol consumption in a population of young adults with mild traumatic brain injuries and the attendant epidemiological circumstances of the trauma.Subjects and methodsAll cases of mild traumatic brain injury among young adults under 30 with an injury severity score <16 who were treated as inpatients between 2009 and 2012 at our trauma center were analyzed with regard to the influence of alcohol consumption by multiple regression analysis.Results793 patients, 560 men, and 233 women were included. The age median was 23 (range 14–30). Alcohol consumption was present in 302 cases. Most common trauma mechanism was interpersonal violence followed by simple falls on even ground. Alcohol consumption was present more often in men, unemployed men, patients who had interpersonal violence as a trauma mechanism, and in patients who were admitted to the hospital at weekends or during night time. It also increased the odds ratio to suffer concomitant injuries, open wounds, or fractures independently from the trauma mechanism. Length of hospital stay or incapacity to work did not increase with alcohol consumption.ConclusionsAmong young adults men and unemployed men have a higher statistical probability to have consumed alcohol prior to suffering mild traumatic brain injury. The most common trauma mechanism in this age group is interpersonal violence and occurs more often in patients who have consumed alcohol. Alcohol consumption and interpersonal violence increase the odds ratio for concomitant injuries, open wounds, and fractures independently from another.

Is rivaroxaban associated with higher morbidity and mortality in patients with traumatic head injuries? A retrospective cohort study comparing rivaroxaban, no anticoagulation, and phenprocoumon

OBJECTIVES The use of new anticoagulants potentially carries the risk of increased intracranial bleeding, but there is a lack of evidence. The aim of this study was to investigate whether the morbidity and mortality differs in head trauma patients depending on the type of anticoagulation. PATIENTS AND METHODS A retrospective cohort study was conducted in 2009-2014. Based on sex, age, and Glasgow-Coma Scale (GCS), patients that received rivaroxaban were matched to two control groups, one that received no anticoagulant and another one that received phenprocoumon. The primary outcome was mortality. Among others, secondary outcome variables were the length of stay (LOS) at the hospital and presence of an intracranial injury. RESULTS Sixty-nine patients (23 patients per group) were analyzed. The characteristics of patients did not differ significantly across groups. There were no significant differences between groups for the primary and secondary outcomes. Two patients died in the rivaroxaban group (one of them likely due to head trauma), while one patient died in the phenprocoumon group (likely not due to head trauma), and no patient died in the no anticoagulatoin group (p = 0.36). The LOS at the hospital was similar (5.0, 4.0, and 5.0 days; p = 0.94). An intracranial injury was observed in a similar number of patients in all groups (n = 11, n = 10, and n = 8; p = 0.75). CONCLUSION Although limited in size, this study did not observe significant outcome differences in patients with traumatic head injuries, who received rivaroxaban, no anticoagulant or phenprocoumon. Although not significant, the only death likely due to head trauma in the study occurred in the rivaroxaban group. Larger studies are needed before clinical application of these findings.

Total inpatient treatment costs in patients with severe burns: towards a more accurate reimbursement model

PRINCIPLES Reimbursement systems have difficulties depicting the actual cost of burn treatment, leaving care providers with a significant financial burden. Our aim was to establish a simple and accurate reimbursement model compatible with prospective payment systems. METHODS A total of 370 966 electronic medical records of patients discharged in 2012 to 2013 from Swiss university hospitals were reviewed. A total of 828 cases of burns including 109 cases of severe burns were retained. Costs, revenues and earnings for severe and nonsevere burns were analysed and a linear regression model predicting total inpatient treatment costs was established. RESULTS The median total costs per case for severe burns was tenfold higher than for nonsevere burns (179 949 CHF [167 353 EUR] vs 11 312 CHF [10 520 EUR], interquartile ranges 96 782-328 618 CHF vs 4 874-27 783 CHF, p <0.001). The median of earnings per case for nonsevere burns was 588 CHF (547 EUR) (interquartile range -6 720 - 5 354 CHF) whereas severe burns incurred a large financial loss to care providers, with median earnings of -33 178 CHF (30 856 EUR) (interquartile range -95 533 - 23 662 CHF). Differences were highly significant (p <0.001). Our linear regression model predicting total costs per case with length of stay (LOS) as independent variable had an adjusted R2 of 0.67 (p <0.001 for LOS). CONCLUSIONS Severe burns are systematically underfunded within the Swiss reimbursement system. Flat-rate DRG-based refunds poorly reflect the actual treatment costs. In conclusion, we suggest a reimbursement model based on a per diem rate for treatment of severe burns.

Reimbursement of care for severe trauma under SwissDRG

QUESTIONS Treatment of patients with severe injuries is costly, with best results achieved in specialised care centres. However, diagnosis-related group (DRG)-based prospective payment systems have difficulties in depicting treatment costs for specialised care. We analysed reimbursement of care for severe trauma in the first 3 years after the introduction of the Swiss DRG reimbursement system (2012-2014). MATERIAL/METHODS The study included all patients with solely basic insurance, hospital admission after 01.01.2011 and discharge in 2011 or 2012, who were admitted to the resuscitation room of the University Hospital of Zurich, aged ≥16 years and with an injury severity score (ISS) ≥16 (n = 364). Clinical, financial and administrative data were extracted from the electronic medical records. All cases were grouped into DRGs according to different SwissDRG versions. We considered results to be significant if p ≤0.002. RESULTS The mean deficit decreased from 12 065 CHF under SwissDRG 1.0 (2012) to 2 902 CHF under SwissDRG 3.0 (2014). The main reason for the reduction of average deficits was a refinement of the DRG algorithm with a regrouping of 23 cases with an ISS ≥16 from MDC 01 to DRGs within MDC21A. Predictors of an increased total loss per case could be identified: for example, high total number of surgical interventions, surgeries on multiple anatomical regions or operations on the pelvis (p ≤0.002). Psychiatric diagnoses in general were also significant predictors of deficit per case (p<0.001). CONCLUSION The reimbursement for care of severely injured patients needs further improvement. Cost neutral treatment was not possible under the first three versions of SwissDRG.

The impact of public versus private insurance on trauma patients

BACKGROUND The socioeconomic status has been associated with disparities in the incidence and mortality of traumatic injuries. However, there is a lack of studies on the level of health insurance with regard to various epidemiologic data of traumatic injuries, which this study opted to clarify. MATERIALS AND METHODS All consecutive 6595 patients admitted to a level one trauma center in 2012 and 2013 were included in this retrospective cohort study. Patients were grouped according to their health insurance status (public versus private extended health care insurance) and compared with regard to several epidemiologic variables, that is, the type of injuries, inhospital outcome, and surgical procedures. RESULTS Public insurance coverage was significantly more common than private insurance (75% versus 25%). Public insurance was associated with younger age, male sex, transfers to another hospital or mental institution, head concussions, head fractures, and increased mortality. Contrarily, patients with private insurance were more often associated with longer hospital stay, discharge to a rehabilitation clinic, fractures of the proximal humerus, and shoulder dislocations. However, there were no significant differences for the remaining majority of studied variables. CONCLUSIONS In a trauma setting, the level of insurance does not seem to play a crucial role in most types of injuries and surgical procedures in a country with a high level of obligatory health care coverage. Nonetheless, it appears that publicly insured patients are more commonly younger, males, transferred to another hospital more often, more prone to head trauma, and subject to increased mortality, whereas privately insured patients show longer hospital stays, increased transfers to rehabilitation clinics, and more fractures of the proximal humerus.
