Equations were developed to predict the weight of trimmed retail (bone-in) cuts, trim, fat and bone from 321 lamb carcasses, ranging in carcass weight from 4.8 to 26.8 kg and in fat depth at the GR site (12th rib) from 1 to 31 mm. For commercial application, the equations were developed using a multiple regression program with the predictors carcass weight and GR. All equations explained a large amount of the variation in component weights (r2 = 0.76-0.99). A time and motion study using 172 carcasses showed that the times required to butcher carcasses of low fat (score 1 and 2) were similar. Likewise the mean time taken to butcher score 3 carcasses was similar to that of score 1 carcasses. However, it took significantly longer (P<0.05) to butcher score 3 carcasses than score 2 carcasses, and score 4 and 5 carcasses than score 3 carcasses. In addition, the mean times taken to butcher score 4 and 5 carcasses were significantly different (P< 0.05). By using multiple regression analysis it was shown that carcass weight, fatscore, their interaction and the butcher all significantly affected the butchering time. The findings of this work are discussed as they apply to the commercial development of price schedules and show that, when based on yield, lean heavy carcasses are more profitable for processing.

Background Diabetes self-management education and support improves diabetes-related outcomes, but many persons living with diabetes do not receive this. Adults with diabetes have high hospitalization rates, so hospital stays may present an opportunity for diabetes education. Nurses, supported by patient care technicians, are typically responsible for delivering patient education but often do not have time. Using technology to support education delivery in the hospital is one potentially important solution. Objective The aim of this study was to evaluate nurse and patient care technician workflow to identify opportunities for providing education. The results informed implementation of a diabetes education program on a tablet computer in the hospital setting within existing nursing workflow with existing staff. Methods We conducted a time and motion study of nurses and patient care technicians on three medical-surgical units of a large urban tertiary care hospital. Five trained observers conducted observations in 2-hour blocks. During each observation, a single observer observed a single nurse or patient care technician and recorded the tasks, locations, and their durations using a Web-based time and motion data collection tool. Percentage of time spent on a task and in a location and mean duration of task and location sessions were calculated. In addition, the number of tasks and locations per hour, number of patient rooms visited per hour, and mean time between visits to a given patient room were determined. Results Nurses spent approximately one-third of their time in direct patient care and much of their time (60%) on the unit but not in a patient room. Compared with nurses, patient care technicians spent a significantly greater percentage of time in direct patient care (42%; P=.001). Nurses averaged 16.2 tasks per hour, while patient care technicians averaged 18.2. The mean length of a direct patient care session was 3:42 minutes for nurses and 3:02 minutes for patient care technicians. For nurses, 56% of task durations were 2 minutes or less, and 38% were one minute or less. For patient care technicians, 62% were 2 minutes or less, and 44% were 1 minute or less. Nurses visited 5.3 and patient care technicians 9.4 patient rooms per hour. The mean time between visits to a given room was 37:15 minutes for nurses and 33:28 minutes for patient care technicians. Conclusions The workflow of nurses and patient care technicians, constantly in and out of patient rooms, suggests an opportunity for delivering a tablet to the patient bedside. The average time between visits to a given room is consistent with bringing the tablet to a patient in one visit and retrieving it at the next. However, the relatively short duration of direct patient care sessions could potentially limit the ability of nurses and patient care technicians to spend much time with each patient on instruction in the technology platform or the content.

The various ways of thawing of model food made for comparison of these processes from point of view of duration. The experiments were conducted under condition that the surface temperature of the thawed food did not overcome 15°C. Shortest mean time of thawing was achieved for vacuum-steam thawing. Regarding to the regime chosen the time of thawing varied between 18.4–29 min. The similar process of vacuum thawing with steam generated from hot water placed below the food was also successful. For this process the mean time of thawing was predicted between 30.5 and 35 min. If the starting temperature of the water was below the boiling point at vacuum level in the chamber the time of thawing was much longer (about 49 min). For hot air thawing we have tested two regimes with temperature of air 50 and 70°C. For both air temperatures the times of thawing were similar being 52.1 and 53.6 min, respectively. Microwave thawing was depending on the power of microwave oven. The time of thawing was achieved 28.9 min at power level 1, at power level “thawing” the process duration was 34.4 min.

Purpose: Because overall EMS system response depends on ambulance availability, we conducted a prospective study of the EMS turnaround interval. This interval consists of the delivery and recovery intervals as defined in Spaite's EMS time-interval model.Methods: An on-site observer, while monitoring EMS radio traffic, recorded the delivery and recovery activities of personnel from a large urban EMS system at a university hospital ED. System policy permits a maximum 30 minute turnaround interval. Prospectively defined subintervals were analyzed.Results: A convenience sample of 122 patient deliveries was collected. Observed and radio-reported arrival at the hospital differed by -1′24″; to +11′8″. Time from arrival to removal of the patient from the ambulance averaged 59″ (range 13″-2′53″), and time from patient removal to ED entry averaged 42″ (10″ - 5′22″). While the mean time for the verbal report to ED staff was 33″ (2″-5′20″), it was 0 = 15″ in 36% of cases. Time from ED entry to placement of the patient on an ED bed averaged 2′11″ (33″-9′35″). Writing the report averaged 17′12″ (5′20″-52′11″). The mean time off radio was 29′51″ (ll′43″-53′37″) and the mean time the ambulance was at the ED was 30′01″ (11′25″-1°17′53″). Observed and radio-reported ambulance departures differed by -4′31″ to +23′32″. In 22% of cases, departure was reported on radio more than 5′after actual departure.

A model is presented for a bounded growth population subjected to random-sized emigrations that occur due to population pressure. The deterministic growth component examined in detail is defined by a Prendiville process. Results are obtained for the times between emigration events and for the population increase between emigrations. Some information is obtained about the mean time to extinction and also for the mean population level when the emigration-size distribution is negative exponential.

Purpose: To report a novel technique (“paper rail”) to facilitate inserting the tail of a microguidewire into the tip of a low-profile device during endovascular procedures. Technique: A sterilized nonwoven fabric tape with a smooth glossy paper backing is used. The tape has several linear folds ideal for a paper rail. Holding each piece of equipment about 5 cm from its respective tip, both the tail of the guidewire and the tip of the catheter are navigated at a 30° angle toward each other in the crease until the guidewire enters the catheter. The paper rail technique was compared with the conventional freehand method under varying luminosities found in an operating room. The paper rail technique was most effective in suboptimal lighting, where the mean time was reduced from 83 seconds with the conventional method to 20 seconds with the paper rail maneuver. The times required to insert the wire with the paper rail method were comparable (~22 seconds) at all light levels. Conclusion: The paper rail method may help improve the speed and accurate insertion of the tail of a microguidewire into the tip of low-profile devices during endovascular procedures. It may be particularly useful for physicians in a low-light environment or trainees.

Background: Multiple perforations in the floor of the oval fossa may be an obstacle for transcatheter closure. Thus, we analyzed the interventions in 33 patients with more than one interatrial communication in comparison with 370 procedures with a single defect. Methods and Results: A diagnostic catheterization, which included a balloon-sizing maneuver, was performed. We implanted a total of 46 occluders, made up of 42 Amplatzers and 4 CardioSEALs. In 20 patients, the defects were closed with a single occluder, namely 18 Amplatzer and 2 CardioSEAL devices. Complete closure was achieved in 15 patients, while a tiny residual shunt remained in 5 patients. In 13 patients, two devices were implanted, without any residual shunt being found immediately after implantation. In 3 patients, the occluders did not touch each other. In 10 patients, their rims overlapped. In comparison with the control group, the group with multiple defects did not differ in the distribution of age, gender, and indications for device closure. The mean time of the procedure, and the time required for fluoroscopy, however, were significant longer (P< 0.001). These times ranged from 45 to 250 minutes with a median of 140 minutes, and from 0.0 to 39.2 minutes, with a median of 12.0 minutes, respectively. Also, the association with an atrial septal aneurysm was significantly more frequent 61 vs. 17%; P< 0.001). The times taken during insertion of double devices were also significantly longer than those needed for insertion of a single device (P< 0.001). Conclusions: Transcatheter closure of multiple defects within the oval fossa is feasible with currently available occluders, albeit than, in selected cases it is necessary to implant two devices.

Abstract Background Rituximab (MabThera®; Rituxan®) is the standard treatment for indolent non-Hodgkin's lymphoma (iNHL). Results from the phase 3 SABRINA study (NCT01200758) showed that a fixed-dose subcutaneous (SC) formulation of rituximab shortened administration time without compromising efficacy or safety compared with intravenous (IV) infusion of rituximab. A switch to the SC formulation is expected to offer healthcare professionals (HCP) time and cost savings. Aims This study aims to quantify resource utilization in terms of active HCP time (ie, time actively dedicated to a patient) and chair time related to rituximab SC vs rituximab IV in the treatment of patients with iNHL and to estimate potential time and cost savings for the conversion from IV to SC (per administration session and for the first year of treatment). Methods This is a multinational, multicenter, prospective, observational time and motion study. Data for rituximab SC injections were collected alongside the MABCUTE (MO25455; NCT01461928) trial, while data for rituximab IV infusions were collected in a real-world setting in the same data collection period and in 23 centers in Italy (IT), Russia (RU), Slovenia (SL), United Kingdom (UK), Spain (SP), France (FR), Austria (AU), and Brazil (BR). Following interviews with a nurse and pharmacy member in each center, generic case report forms for IV, SC, and drug preparation area (including pharmacy) processes were tailored to reflect local site practices. Trained observers recorded both the time that HCPs were actively completing prespecified tasks (using a stopwatch), and patient chair time (based on length of time between patients entering and exiting chairs). This is a descriptive study with convenience-based sample sizes. A random effects regression model was run for each task (pooled sample by country) to generate task mean and 95% confidence interval (CI) using appropriate distributions. IV vs SC process time per patient was calculated as the sum of the mean task times. Results The difference in mean active HCP time saved by switching from rituximab IV to rituximab SC ranged from 6.8 min in AU to 38.4 min in the UK (Table 1). The proportionate reduction in mean HCP time ranged from 27% in SP to 57% in RU. The mean time saved (% reduction) in the treatment room ranged from 0.3 min (2%) in SP to 25.4 min (63%) in the UK. Over the course of the first-year of treatment (6 induction and 3 maintenance sessions), the estimated reduction in total HCP time associated with the switch ranged from 0.9 hr in AU to 5.1 hr in the UK. The differences in mean chair time saved with SC over IV administration ranged from 126.1 min in SL (64%) to 280.1 min (86%) in IT. Simulating these findings for a hypothetical center treating 50 patients for 9 sessions annually indicated that the amount of chair time freed would range from 105.1 (SL) to 233.4 (IT) 8-hour days. Staff opportunity cost estimates will be presented at the conference. Conclusions The current analysis indicates that a switch from rituximab IV to rituximab SC leads to a substantial reduction in administration chair time and in active HCP time. These time savings could allow more time to be used for other patient care activities, increasing the number of patients who could be treated and thus increasing the overall efficiency of treatment centers.
