Radiation from ingested wireless devices in bio-medical telemetry bands

The performance of wireless devices, using electrically small antennae, in the human intestine is investigated using the finite difference time domain method in recommended biomedical device telemetry bands. The radiation field intensity was found to depend on position but more strongly on frequency, with a transmission peak at 650 MHz

An Updated Rounds Checklist to Increase Appropriate Use of Telemetry Monitoring

Background: Telemetry monitoring is an essential tool to monitor cardiac electrical activity. Its overuse is costly in time and resources and leads to subsequent testing and treatments that are not necessary for the patient and, in addition, healthcare staff is burdened with work that is potentially not clinically useful. Aim: The global aim of increasing efficiency in telemetry use starts with the local improvement to facilitate nurse-physician communication of telemetry patients during Methods: This study with pre and post data collection looked at the results of quantitative data, collected in May-July 2015, on the number of patients with telemetry and the corresponding clinical indication before and after implementation of a modified rounds checklist which included telemetry as a discussion point. The new checklist was initiated on June 22, 2015 and post intervention data was gathered to determine if there was a decrease in the overuse of and increase in the appropriate use of telemetry. Results: With the implementation of the checklist the use of telemetry decreased, however the clinical indication for use did not improve. Conclusion and implications for CNL practice: After the implementation of the checklist criteria there has been a consistent decrease in telemetry use. This may attributable to improve nurse-physician communication, however, there is still a lack of appropriate clinical indication of use and the CNL, as lateral integrator, in future improvement projects, should support further modifications to the clinical indication set to improve appropriateness of telemetry use

Case presentation, current practices of telemetry management, root cause analysis, goals for improvement, proposed intervention and next steps

Improved television signal processing system

Digital system processes spacecraft television pictures by converting images sensed on a photostorage vidicon to pulses which can be transmitted by telemetry. This system can be applied in the processing of medical X ray photographs and in electron microscopy

Comparison of Nurse Staffing Based on Changes in Unit-level Workload Associated with Patient Churn

Aim This analysis compares the staffing implications of three measures of nurse staffing requirements: midnight census, turnover adjustment based on length of stay, and volume of admissions, discharges and transfers. Background Midnight census is commonly used to determine registered nurse staffing. Unit-level workload increases with patient churn, the movement of patients in and out of the nursing unit. Failure to account for patient churn in staffing allocation impacts nurse workload and may result in adverse patient outcomes. Method(s) Secondary data analysis of unit-level data from 32 hospitals, where nursing units are grouped into three unit-type categories: intensive care, intermediate care, and medical surgical. Result Midnight census alone did not account adequately for registered nurse workload intensity associated with patient churn. On average, units were staffed with a mixture of registered nurses and other nursing staff not always to budgeted levels. Adjusting for patient churn increases nurse staffing across all units and shifts. Conclusion Use of the discharges and transfers adjustment to midnight census may be useful in adjusting RN staffing on a shift basis to account for patient churn. Implications for nursing management Nurse managers should understand the implications to nurse workload of various methods of calculating registered nurse staff requirements

The Use of Telemetry Monitoring Among General Medicine Patients

Objective: To determine why and when general medicine non-ICU patients are upgraded from a non-telemetry level of care to telemetry monitoring at Thomas Jefferson University Hospital (TJUH). Comparison of the reasons for initiation of continuous ECG monitoring with the AHA and ACC guidelines would provide a greater understanding of the applicability of these recommendations to non-ICU general medicine patients. This information can provide guidance to identify areas of intervention to decrease inappropriate and/or overutilization of telemetry. The ultimate goal is to identify general medicine patients who are likely to benefit from continuous ECG monitoring, without negatively affecting clinical outcomes for those who do not receive cardiac monitoring.https://jdc.jefferson.edu/patientsafetyposters/1025/thumbnail.jp

Video-EEG long term monitoring as a new service at Mater Dei Hospital

Introduction: Video-EEG long-term monitoring (LTM) was introduced into Mater Dei Hospital (MDH) in May 2012. The audit aims to evaluate LTM in terms of diagnostic outcomes and impact on patient management. Methods: Analysis was carried out after retrospective review of 30 inpatients who underwent LTM at MDH between May 2012 and May 2014. 31 LTM sessions were performed. Referrals were made by 3 consultant neurologists. LTM and medical records were compared to evaluate whether LTM determined a change in diagnosis and how this affected management outcomes. Results: Patient ages ranged from 3 months to 73 years (35.5% paediatric cases) (16 male , 15 female studies). The most common indication was for uncontrolled seizures (54.8%), followed by suspected non-epileptic seizures (NES) (29%). The average hospital stay was 2 days for paediatric patients and 5 for adult cases. Major monitoring interruptions were recorded in 5 paediatric and 1 adult case. Comparing pre- with post-LTM diagnosis showed that the investigation changed or identified a new diagnosis in 38.7%, confirmed the diagnosis in 29%, and was inconclusive in 32.3% (inconclusive in 45.5% of paediatric cohort and 25% of adult cohort). It led to medication optimisation in 38.7% and neuropsychiatry referrals in 22.6%. The remaining were unchanged, not followed up or referred for other tests. None were referred for surgery. Conclusion: LTM is an important tool which influenced patient management through changes in medication or referrals in 64.5% of cases. Continuous evaluation of the techniques used and resources available is recommended to increase the yield of conclusive LTM studies.peer-reviewe

An Integrated Framework for Sensing Radio Frequency Spectrum Attacks on Medical Delivery Drones

Drone susceptibility to jamming or spoofing attacks of GPS, RF, Wi-Fi, and operator signals presents a danger to future medical delivery systems. A detection framework capable of sensing attacks on drones could provide the capability for active responses. The identification of interference attacks has applicability in medical delivery, disaster zone relief, and FAA enforcement against illegal jamming activities. A gap exists in the literature for solo or swarm-based drones to identify radio frequency spectrum attacks. Any non-delivery specific function, such as attack sensing, added to a drone involves a weight increase and additional complexity; therefore, the value must exceed the disadvantages. Medical delivery, high-value cargo, and disaster zone applications could present a value proposition which overcomes the additional costs. The paper examines types of attacks against drones and describes a framework for designing an attack detection system with active response capabilities for improving the reliability of delivery and other medical applications.Comment: 7 pages, 1 figures, 5 table
