{"title":"Dynamic control assignment and automated risk assessment for external control interfaces in the operating room based on ISO IEEE 11073 SDC","authors":"Noah Wickel, O. Yilmaz, K. Radermacher, A. Janß","doi":"10.54941/ahfe1003943","DOIUrl":"https://doi.org/10.54941/ahfe1003943","url":null,"abstract":"Surgical procedures require a variety of medical devices, each bearing an ever-increasing number of settings and functions. Most devices are placed in the unsterile area of the operating room. Therefore, the surgeon and other sterile staff members are not able to interact with the device interfaces. Surgeons often rely on so-called ‘yell-and-click communication’ to have a setting changed, which is error-prone, slow and moreover leads to process interruptions for the involved OR personnel. Suitable control devices, like a foot switch or a sterile user interface, can allow sterile staff members direct access to certain device functions. In a networked operating room, such control devices could exist for any controllable value or operation. Due to spatial limitations in the OR, it is desired to use as few physical control devices as possible. To control a large variety of parameters, these control devices' associated functionality could be re-assigned during a surgical procedure. The manufacturer-independent communication standard ISO IEEE 11073 SDC is tailored for medical device control in the operating room and makes such a re-assignable control interface technically feasible.However, each control association must be assessed with regard to its usability and risk management. For example, a critical control target must never be controlled by an element which is too coarse for the intended task. Therefore, it is a key requirement to develop a software model for control devices and a mechanism to allow or deny a proposed mapping desired by the user based on safety and usability criteria.In the present work, we outline a system to describe and categorize input devices (control elements such as buttons, knobs and foot switches) and controllable counterparts (Targets) typically found in the surgical context. Great attention is given to the means necessary to safely control critical parameters. We assess the current descriptive capabilities of SDC and propose necessary additions to create more comprehensible software models of the control devices. Finally, we present a new convention for medical device modeling which could be used to propose or prohibit unsafe or unintended mappings in a user interface for configuring control devices in the operating room.","PeriodicalId":107005,"journal":{"name":"Health Informatics and Biomedical Engineering Applications","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128170798","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rehabilitation services are important to maintain the quality of life of the elderly. Clinical therapists share heavy workloads to deliver professional rehabilitation services to the elderly people. Home-based rehabilitation systems are proposed to provide professional training with more flexibility at a convenient time slot and venue. However, most existing home-based rehabilitation systems only provide game for fun or a video-conference platform to have one-to-one training with a therapist. In this study, we designed a home-based augmented reality (AR) rehabilitation system which integrates more than 45 professional rehabilitation training exercises designed by physical therapists and occupational therapists, combined with real-time AR guidance to provide feedback to users’ motions. The new platform does not require the therapist to be online during the time of training and it provides real-time guidance based on users’ 3D body segment motion. A pilot trial was conducted by recruiting 10 elderly subjects with disability to receive a 20 sessions of rehabilitation training using the AR rehabilitation training system. The AR rehabilitation training system can provide an objective and comprehensive performance report for users after each exercise session, which include the score of the corresponding exercise, the curves and the measurement of the significant biomechanics data. The results showed that the system could effectively improve the joint movement and body balance. A questionnaire survey was conducted among all the subjects after they finished the training, the results showed that they were very satisfied with the AR rehabilitation system. This study demonstrates that a home-based AR rehabilitation system has the potential to be applied in clinical application to support the elderly people to improve their physical dysfunction and maintain their quality of life.","PeriodicalId":107005,"journal":{"name":"Health Informatics and Biomedical Engineering Applications","volume":"136 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121332990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kinect V2 seemed not feasible to easily track motion in a lying position, while the latest Microsoft Azure Kinect has improved the sensor. This paper experimentally explores the feasibility of Azure Kinect and Kinect V2 for lying position rehabilitation exercises and evaluate the tracking performance by changing the camera viewing angles. Two healthy subjects performed upper and lower limb rehabilitation exercise trial on the bed according to supine position and lateral position. The Kinect sensor was tested at 6 viewing angles in human body coronal plane and sagittal plane. Subject motion data and video were recorded and evaluated by two Kinect camera systems. The results showed that the hardware improvement such as resolution enhancement and the neural network motion tracking algorithm of the Azure Kinect depth camera led to higher performance in lying body motion recognition than Kinect v2 for most of the viewing angles. In conclusion, Azure Kinect could improve the lying position body tracking accuracy and it has great potential in the field of rehabilitation with lying position exercises.","PeriodicalId":107005,"journal":{"name":"Health Informatics and Biomedical Engineering Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129219879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Jiang, Lauren Davis","doi":"10.54941/ahfe1003452","DOIUrl":"https://doi.org/10.54941/ahfe1003452","url":null,"abstract":"Food banks are at the forefront of the battle against food insecurity which is a condition where households do not have adequate access to food. Traditionally speaking, food banks focus on distributing food to meet the needs. Recently, more food banks are shifting to supply adequate healthy food based on the populations they serve. However, the question remains whether a local food bank can find racial communities in need with dietary considerations. This study's purpose is to use data collected by a local food bank and create visualizations to aid strategic decision-making for the food bank to recognize racial communities with those who have dietary considerations. Results revealed nine out of sixteen counties in the service area of the local food bank have the highest number of African Americans allergic to shellfish compared to a few counties having the highest number of Whites, American Indians, and Hispanic/Latinos. Additionally, 53.7% of African Americans, 11.2% of Hispanics and Latinos, and 34.3% of Whites face lactose intolerance. Data shows that African Americans have the highest number of dietary considerations in most categories that are in several counties. The significance of this study supports a local food bank in finding dietary considerations within the areas they serve. Finding racial communities that face dietary considerations will aid the local food bank in making better strategic decisions on what types of food they should serve and where. Ultimately, the importance of this study is to combat food insecurity and hunger, so that members of the local food bank community can have dignity in knowing the food that will be given is valuable and not wasted.","PeriodicalId":107005,"journal":{"name":"Health Informatics and Biomedical Engineering Applications","volume":"239 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116065558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The process of liver damage develops with varying intensity and does not immediately lead to irreversible consequences; therefore, dysfunction should be detected as early as possible, and the data obtained should be used to assess the current state and predict their reversibility.Study purpose. To create a quantitative assessment method that allows to assess the current functional state of the liver and to determine the reversibility of existing functional disorders and the severity of structural changes, to assess the prognosis of the course of the disease and the effectiveness of restorative measures.Instruments and Data Collection Procedure. Examination of patients, in addition to conventional methods, included an assessment of the absorptive-excretory function of the liver and biliary tract patency using a scintillation gamma camera (Siemens Symbia T16) with subsequent processing on the SUPER-SEGAMS computer system (Hungary). Freshly prepared Bromesida, 99mТс was administered intravenously at the rate of 1.1 MBq per kg of the patient's body weight, with a normal content of bilirubin in blood. Series of scintigrams allow to assess the passage of the drug visually through the blood-liver-ducts-intestine system, to characterize the anatomical features and organic changes in the biliary system. Quantitative analysis of the \"activity-time\" curves obtained from the areas of interest (the right lobe of the liver - 2 zones, the left lobe of the liver, the common bile duct, the intestinal area, the heart area) makes it possible to study the absorptive-excretory function of the liver.Results. By the method of mathematical modeling, a formula was obtained - the index of the functional activity of hepatocytes:IFAH= (-1,1564 + 0,0653 × BMI - 0,0144 × Tmax) × 100,where:IFAH - index of functional activity of hepatocytes (liver cells);BMI - body mass index (kg/m2)Tmax - indicator of the absorption function of the liver (min) - the time to reach the maximum accumulation of the radiopharmaceutical in the liver. It is an indicator of the function of polygonal liver cells (normal = 8-12 min).Functional activity of hepatocytes: from 0 to 9.9 - normal functional activity of hepatocytes; from 10 to 19.9 - the risk of developing functional disorders; from 20 to 29.9 - reversible dysfunction of hepatocytes (steatosis); more than 30 - irreversible (organic) liver dysfunction (steatohepatitis).

A well-accepted solution to the problem is tall-man lettering, a typographic alteration to drug names. However, studies of its effectiveness have yielded mixed results. Furthermore, the potential of orthographic alterations to drug names has not been explored. Therefore, this study aims to examine the usefulness of the combination of tall-man lettering and a simple but new orthographic alteration, symbol prefixing. Twenty-six outpatient pharmacists were recruited to participate in an experiment on drug identification. The results showed that first, the accuracy of drug identification increased with tall-man lettering. Next, the response time and the number of eye fixations for the identification decreased with tall-man lettering and symbol prefixing. Finally, the number of eye fixations decreased with symbol prefixing when there was no tall-man lettering. The findings support that tall-man lettering and symbol prefixing are effective techniques for helping pharmacists identify drugs. Further research could assess the impacts of different types of typographic and orthographic alterations for alleviating the problem of drug name confusion and ultimately minimizing medication errors and ensuring patient safety.","PeriodicalId":107005,"journal":{"name":"Health Informatics and Biomedical Engineering Applications","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131527030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
