Results of a Time and Motion Survey Regarding Subcutaneous versus Intravenous Administration of Daratumumab in Patients with Relapsed or Refractory Multiple Myeloma.

PURPOSE: Daratumumab (DARA) is a humanized anti-CD38 monoclonal antibody and approved as monotherapy or in combination with standard of care regimens for the treatment of multiple myeloma (MM). DARA intravenous (IV) administration is time-consuming; availability of DARA subcutaneous (SC) is expected to reduce this burden. A time and motion survey was undertaken to elicit healthcare providers' (HCPs') understanding of the workflow and time estimates for administration of DARA IV and SC (beyond treatment time) in patients with relapsed/refractory MM. PATIENTS AND METHODS: This web-based, prospective survey collected data from HCPs at sites that actively enrolled patients in the phase 3 COLUMBA trial, a multicenter, noninferiority study of DARA IV versus DARA SC. Data collection included time actively spent on pre-specified drug preparation and drug administration/patient care activities; active HCP and chair time were extrapolated for first and subsequent treatments. RESULTS: Compared with DARA IV, DARA SC reduced median total active HCP time by 63.8% (from 265.9 to 96.3 minutes) and 49.5% (from 179.2 to 90.4 minutes) for first and subsequent treatments, respectively. When extrapolated to the anticipated number of treatments per year (23 in Year 1 and 13 in Year 2, per label), estimated active HCP time per patient was reduced by 50% in Years 1 (from 70.1 to 34.8 hours) and 2 (from 38.8 to 19.6 hours) for DARA SC versus DARA IV. Estimated chair time for DARA SC was decreased by 97% versus DARA IV for first (from 456.9 to 13.3 minutes) and subsequent treatments (from 238.0 to 8.1 minutes). CONCLUSION: These results suggest that DARA SC is associated with less active HCP involvement during drug preparation and drug administration/patient care compared with DARA IV, potentially reducing burdens on patients and caregivers and creating efficiencies for HCPs and healthcare facilities, allowing more patients access to care.

Air embolism during operative hysteroscopy: TEE-guided resuscitation.

During hysteroscopic surgery there are concerns about potential complications such as venous air and gas embolism. The incidence of subclinical air emboli events during operative hysteroscopy is significantly underestimated. The manifestations of this complication may range from an unnoticeable decrease in P(ET)CO(2) to the need for resuscitation. Three cases of air embolism with variable outcomes occurring during general anesthesia for operative hysteroscopy in otherwise healthy patients are presented.

Early postoperative cognitive dysfunction and postoperative delirium after anaesthesia with various hypnotics: study protocol for a randomised controlled trial--the PINOCCHIO trial.

BACKGROUND: Postoperative delirium can result in increased postoperative morbidity and mortality, major demand for postoperative care and higher hospital costs. Hypnotics serve to induce and maintain anaesthesia and to abolish patients' consciousness. Their persisting clinical action can delay postoperative cognitive recovery and favour postoperative delirium. Some evidence suggests that these unwanted effects vary according to each hypnotic's specific pharmacodynamic and pharmacokinetic characteristics and its interaction with the individual patient.We designed this study to evaluate postoperative delirium rate after general anaesthesia with various hypnotics in patients undergoing surgical procedures other than cardiac or brain surgery. We also aimed to test whether delayed postoperative cognitive recovery increases the risk of postoperative delirium. METHODS/DESIGN: After local ethics committee approval, enrolled patients will be randomly assigned to one of three treatment groups. In all patients anaesthesia will be induced with propofol and fentanyl, and maintained with the anaesthetics desflurane, or sevoflurane, or propofol and the analgesic opioid fentanyl.The onset of postoperative delirium will be monitored with the Nursing Delirium Scale every three hours up to 72 hours post anaesthesia. Cognitive function will be evaluated with two cognitive test batteries (the Short Memory Orientation Memory Concentration Test and the Rancho Los Amigos Scale) preoperatively, at baseline, and postoperatively at 20, 40 and 60 min after extubation.Statistical analysis will investigate differences in the hypnotics used to maintain anaesthesia and the odds ratios for postoperative delirium, the relation of early postoperative cognitive recovery and postoperative delirium rate. A subgroup analysis will be used to categorize patients according to demographic variables relevant to the risk of postoperative delirium (age, sex, body weight) and to the preoperative score index for delirium. DISCUSSION: The results of this comparative anaesthesiological trial should whether each the three hypnotics tested is related to a significantly different postoperative delirium rate. This information could ultimately allow us to select the most appropriate hypnotic to maintain anaesthesia for specific subgroups of patients and especially for those at high risk of postoperative delirium.

The effect of intensive insulin therapy on infection rate, vasospasm, neurologic outcome, and mortality in neurointensive care unit after intracranial aneurysm clipping in patients with acute subarachnoid hemorrhage: a randomized prospective pilot trial.

It is unclear if avoiding hyperglycemia during intensive care after acute brain injury improves morbidity, mortality, and neurologic outcome. This prospective randomized trial tested whether intensive insulin therapy affected infection rates, vasospasm, mortality, or long-term neurologic outcome in subarachnoid hemorrhage patients during their intensive care unit (ICU) stay. Comparison was made against conventional insulin therapy using a randomized trial design. The primary outcome measure was infection rate until the fourteenth postoperative day in the ICU or until patient discharge. Secondary end points were the incidence of vasospasm until the fourteenth postoperative day in the ICU or until patient discharge, and neurologic outcome and mortality at 6 months follow-up. A total of 78 patients were prospectively enrolled and randomly assigned either to conventional insulin therapy or to intensive insulin therapy (38 and 40 patients, respectively). The infection rate during the study was significantly higher in patients who received conventional insulin therapy than in patients who received intensive insulin therapy (42% vs. 27%; P<0.001). The incidence of vasospasm during the study was also similar in conventional and intensive therapy groups (31.5% vs. 27.6% in the conventional and intensive insulin therapy groups; P=0.9). Overall mortality rates at 6 months were similar in the 2 groups (18% vs.15%; P=0.9), as was the neurologic outcome at 6 months [modified Rankin score >3 in 22/38 patients (57.8%) in the conventional therapy group vs. 21/40 patients (52.5%) in the intensive insulin therapy group; P=0.7]. Intensive insulin therapy in patients with acute subarachnoid hemorrhage admitted to a postoperative neurosurgical ICU after surgical clipping of intracranial aneurysms decreases infection rates. The benefit of strict glycemic control on postoperative vasospasm, neurologic outcome, and mortality rates does not seem to be affected by intensive insulin therapy.
