Automated Annotation of Sphingolipids Including Accurate Identification of Hydroxylation Sites Using MSn Data.

Sphingolipids constitute a heterogeneous lipid category that is involved in many key cellular functions. For high-throughput analyses of sphingolipids, tandem mass spectrometry (MS/MS) is the method of choice, offering sufficient sensitivity, structural information, and quantitative precision for detecting hundreds to thousands of species simultaneously. While glycerolipids and phospholipids are predominantly non-hydroxylated, sphingolipids are typically dihydroxylated. However, species containing one or three hydroxylation sites can be detected frequently. This variability in the number of hydroxylation sites on the sphingolipid long-chain base and the fatty acyl moiety produces many more isobaric species and fragments than for other lipid categories. Due to this complexity, the automated annotation of sphingolipid species is challenging, and incorrect annotations are common. In this study, we present an extension of the Lipid Data Analyzer (LDA) "decision rule set" concept that considers the structural characteristics that are specific for this lipid category. To address the challenges inherent to automated annotation of sphingolipid structures from MS/MS data, we first developed decision rule sets using spectra from authentic standards and then tested the applicability on biological samples including murine brain and human plasma. A benchmark test based on the murine brain samples revealed a highly improved annotation quality as measured by sensitivity and reliability. The results of this benchmark test combined with the easy extensibility of the software to other (sphingo)lipid classes and the capability to detect and correctly annotate novel sphingolipid species make LDA broadly applicable to automated sphingolipid analysis, especially in high-throughput settings.

Adherence to growth hormone (GH) therapy in naïve to treatment GH-deficient children: data of the Italian Cohort from the Easypod Connect Observational Study (ECOS).

BACKGROUND: With the use of non-objective measurement, adherence to growth hormone (GH) therapy has been reported suboptimal in a large proportion of patients, and poor adherence has been shown to affect short-term growth response in patients receiving GH treatment. OBJECTIVE: The Easypod™ electronic device allows objective measurement of adherence. In this study, we report 3-year prospective adherence data of the Italian cohort of naïve GH deficient (GHD) children extrapolated from the Easypod Connect Observational Study (ECOS) database. PATIENTS AND METHODS: Seventy-three GHD children naïve to GH treatment were included in the analysis. 22 Italian centers participated in the study. RESULTS: Mean adherence rate was consistently above 85% across the 3-year observation period. Particularly, mean adherence was 88.5%, 86.6%, and 85.7% after 1, 2 and 3 years, respectively. Mean (± SD) height-SDS increase after the first year was 0.41 (± 0.38). CONCLUSIONS: The majority of naïve GHD children starting GH treatment with Easypod maintained an adherence rate > 85% up to 3 years. Easypod is a useful tool to follow-up patients' adherence allowing timely intervention to improve optimal treatment for these patients.

Electronic health records and national patient-safety goals.

Hospitals and clinics are adapting to new technologies and implementing electronic health records, but the efforts need to be aligned explicitly with goals for patient safety. EHRs bring the risks of both technical failures and inappropriate use, but they can also help to monitor and improve patient safety.

Cardiac resuscitation events: one eyewitness is not enough.

OBJECTIVE: To determine the accuracy of paper cardiopulmonary resuscitation records. DESIGN: Case series. SETTING: Twenty-six-bed video-monitored pediatric cardiac ICU. PATIENTS: All patients who had a resuscitation event with available video and electronically stored vital sign and waveform data from May 2012 to February 2013. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: There were 41 cardiopulmonary resuscitation events during the study period. Fifteen had complete and valid data from the paper cardiopulmonary resuscitation forms, the retrieved monitor data, and the continuous bedside video monitoring. These 15 events occurred in 12 individual patients, and there was 100% agreement of data in the documentation of interventions in place (ventilation, arterial catheter, pulse oximetry, and vascular access) and in the presence of a witness at the onset of the arrest. All events were witnessed. Of the 15 events, video and monitor review revealed that 14 used waveform and numeric capnometry to confirm endotracheal tube/tracheostomy placement, but this section was only completed on the paper cardiopulmonary resuscitation record in three of the 14 cases. All records showed no discrepancies in the time of return of spontaneous circulation. The video and monitor review revealed delay in initiating cardiopulmonary resuscitation (mode, 2 min; two cases ≥ 7 min) and shockable rhythms (ventricular arrhythmia) in two cases. A sign of pulseless state was discovered in seven cases classified on the paper record as "always with a pulse." Those include sudden loss of consciousness, flat arterial line tracing, and abrupt drop in the partial pressure of exhaled carbon dioxide tracing (< 10 mm Hg). CONCLUSIONS: Eyewitness accounts of cardiopulmonary resuscitation are often inaccurate and incomplete. Review of information from video and electronically stored vital sign and waveform data provides more accurate information than review of paper-based cardiopulmonary resuscitation records and may provide the insight necessary to improving cardiopulmonary resuscitation.

Toward Successful Implementation of Speech Recognition Technology: A Survey of SRT Utilization Issues in Healthcare Settings.

PURPOSE: To evaluate physician utilization of speech recognition technology (SRT) for medical documentation in two hospitals. METHODS: A quantitative survey was used to collect data in the areas of practice, electronic equipment used for documentation, documentation created after providing care, and overall thoughts about and satisfaction with the SRT. The survey sample was from one rural and one urban facility in central Missouri. In addition, qualitative interviews were conducted with a chief medical officer and a physician champion regarding implementation issues, training, choice of SRT, and outcomes from their perspective. RESULTS: Seventy-one (60%) of the anticipated 125 surveys were returned. A total of 16 (23%) participants were practicing in internal medicine and 9 (13%) were practicing in family medicine. Fifty-six (79%) participants used a desktop and 14 (20%) used a laptop (2%) computer. SRT products from Nuance were the dominant SRT used by 59 participants (83%). Windows operating systems (Microsoft, Redmond, WA) was used by more than 58 (82%) of the survey respondents. With regard to user experience, 42 (59%) participants experienced spelling and grammatical errors, 15 (21%) encountered clinical inaccuracy, 9 (13%) experienced word substitution, and 4 (6%) experienced misleading medical information. CONCLUSIONS: This study shows critical issues of inconsistency, unreliability, and dissatisfaction in the functionality and usability of SRT. This merits further attention to improve the functionality and usability of SRT for better adoption within varying healthcare settings.

Piloting the use of 2D barcode and patient safety-software in an Australian tertiary hospital setting.

OBJECTIVES: Errors in administration of blood products can lead to poor patient outcomes including fatal ABO incompatible transfusions. This pilot study sought to establish whether the use of two-dimensional (2D) barcode technology combined with patient identification software designed to assist in blood administration improves the bedside administration of transfusions in an Australian tertiary hospital. STUDY DESIGN AND METHODS: The study was conducted in a Haematology/Oncology Day Clinic of a major metropolitan hospital, to evaluate the use of 2D barcode technology and patient safety-software and hand-held PDAs to assist nursing staff in patient identification and blood administration. Comparative audits were conducted before and after the technology's implementation. RESULTS: The preimplementation transfusion practice audits demonstrated a poor understanding of the blood checking process, with focus on the product rather than patient identification. Following the implementation of 2D barcode technology and patient safety-software, there was significant improvement in administration practice. Positive, verbal patient identification improved from 57% (51/90) to 94% (75/80). Similarly, the cross-referencing of the patient's identification with the patient's wristband improved from 36% (32/90) to 94% (75/80), and the cross-referencing of patient ID on the compatibility tag to wristbands improved from 48% (43/90) to 99% (79/80). Importantly, the 2D barcode technology and patient safety-software saw 100% (80/80) of checks being conducted at the patient bedside, compared with 76% (68/90) in the preimplementation audits. CONCLUSION: This pilot study demonstrates that 2D barcode technology and patient safety-software significantly improves the bedside check of patient and blood product identification in an Australian setting.

Enhancing the routine health information system in rural southern Tanzania: successes, challenges and lessons learned.

OBJECTIVE: To describe and evaluate the use of handheld computers for the management of Health Management Information System data. METHODS: Electronic data capture took place in 11 sentinel health centres in rural southern Tanzania. Information from children attending the outpatient department (OPD) and the Expanded Program on Immunization vaccination clinic was captured by trained local school-leavers, supported by monthly supervision visits. Clinical data included malaria blood slides and haemoglobin colour scale results. Quality of captured data was assessed using double data entry. Malaria blood slide results from health centre laboratories were compared to those from the study's quality control laboratory. RESULTS: The system took 5 months to implement, and few staffings or logistical problems were encountered. Over the following 12 months (April 2006-March 2007), 7056 attendances were recorded in 9880 infants aged 2-11 months, 50% with clinical malaria. Monthly supervision visits highlighted incomplete recording of information between OPD and laboratory records, where on average 40% of laboratory visits were missing the record of their corresponding OPD visit. Quality of microscopy from health facility laboratories was lower overall than that from the quality assurance laboratory. CONCLUSIONS: Electronic capture of HMIS data was rapidly and successfully implemented in this resource-poor setting. Electronic capture alone did not resolve issues of data completeness, accuracy and reliability, which are essential for management, monitoring and evaluation; suggestions to monitor and improve data quality are made.

Web-based self-management for patients with multiple sclerosis: a practical, randomized trial.

OBJECTIVE: No studies have addressed the use of electronic personal health records (e-PHRs) for self-management in complex neurological disorders. We assessed and tested an Internet-based self-management system that utilized the e-PHR and determined its impact on self-assessed well-being, clinician-assessed well-being, and healthcare utilization in patients with multiple sclerosis (MS). MATERIALS AND METHODS: Subjects were randomized to usual care (a secure Web-based messaging system) or active intervention, which included secure messaging, self-monitoring, self-management of MS symptoms, and communication about upcoming clinic visits. Computers and Internet access were provided. Subjects were included if they had MS, lived within the county or region surrounding our MS center, had at least two appointments at our center in the previous 12 months, and demonstrated basic typing and computer skills. Study duration was 12 months. RESULTS: Of 220 subjects completing informed consent, 206 met the inclusion criteria. At the study's end, 83 subjects remained in the usual care group and 84 in the enhanced care group. Both groups used the available system components. The groups did not significantly differ on the primary endpoints or healthcare utilization. CONCLUSIONS: Self-management support is an emerging aspect of chronic care management. We established the feasibility of conducting a randomized, controlled trial using e-PHRs for patient self-management. We did not find that e-PHR-enabled self-management augmented multidisciplinary MS center-based care, possibly because the differences between interventions were not great enough.

What is found positive in healthcare information and communication technology implementation?-the results of a nationwide survey in Finland.

OBJECTIVE: Considerable expectations have been placed on information and communication technology (ICT) in improving the processes and quality of healthcare. Our purpose was to find out which element is found positive in healthcare ICT implementation. MATERIALS AND METHODS: An online questionnaire on e-Health implementation submitted to all Finnish public health service providers and a sample from the private sector included an open question about which the electronic working methods, systems, or applications have most positively influenced the fluency or quality of service processes. RESULTS: The electronic health record was mentioned as an item that has positive influence by 52% of the respondents from the hospital districts, 27% of those from the primary healthcare centers, and 38% of those from the private providers. Digital radiology systems (including teleradiology) were mentioned by 52% of the hospital districts and 27% of the primary healthcare centers. The figures for digital laboratory systems (including telelaboratory) were 5% and 11%, respectively. The figures for teleradiology itself were 5% for the hospital districts and 15% for the primary healthcare centers; the figures for telelaboratory systems were 5% and 9%, respectively. CONCLUSIONS: The specialized healthcare seem to experience intraorganizational electronic services integrated to the electronic health record, such as digital radiology and laboratory services as exerting a positive influence, whereas the primary healthcare find such influence from different functions such as interorganizational data exchange and telemedicine services. These might indicate where the efforts should be focused when implementing ICT in healthcare.

Establishment of the temporary certification program for health information technology. Final rule.

This final rule establishes a temporary certification program for the purposes of testing and certifying health information technology. This final rule is established under the authority granted to the National Coordinator for Health Information Technology (the National Coordinator) by section 3001(c)(5) of the Public Health Service Act (PHSA), as added by the Health Information Technology for Economic and Clinical Health (HITECH) Act. The National Coordinator will utilize the temporary certification program to authorize organizations to test and certify Complete Electronic Health Records (EHRs) and/or EHR Modules, thereby making Certified EHR Technology available prior to the date on which health care providers seeking incentive payments available under the Medicare and Medicaid EHR Incentive Programs may begin demonstrating meaningful use of Certified EHR Technology.

How to select end user clinical data entry devices. Rush University Medical Center develops tool to identify the quantity of devices needed for the implementation of a new EMR and CPOE system.

Selecting the right types and quantities of computers to support data entry to an inpatient Electronic Medical Record (EMR) can be challenging. In addition to software and hardware considerations, many other variables affect the decision including staffing levels, hospital workflows, and floor plans. Rush University Medical Center (RUMC) developed a tool to help identify the quantity of devices needed in a Patient Care Unit (PCU). RUMC successfully used the tool in selecting the quantity of devices needed for the implementation of a new EMR and Computerized Provider Order Entry (CPOE) system. This case study describes the use of the tool to determine quantities of PCU devices, the advantages and disadvantages of different types of computing devices for bedside documentation and areas that require special considerations in the selection of devices.

Wireless Tech Trends 2010. Trend: smartphones.

UNLABELLED: THE LANDSCAPE: Physician use of handhelds is by no means a new concept. But as the devices--particularly the RIM BlackBerry, Apple iPhone and Google Android--become more sophisticated and more applications become available, the game is changing, quickly. And with so many hospitals upgrading their infrastructures to offer ubiquitous wireless coverage, clinicians are using smartphones in the hospital setting to access online tools such as drug references, and communicate with colleagues. For ClOs, it's a no-brainer--physicians and nurses are already carrying these devices, so why not capitalize on the trend by enabling users to access clinical information and link to patient records. A number of organizations have adopted this thinking and are on the road to enabling EMR access via mobile devices. And while there are certainly sticking points, it's an area that many say is poised for significant growth in the next few years. THE FUTURE: Many innovative organizations are looking to provide access to electronic records and other clinical data through smartphones. Plans are already being formulated to leverage the devices to facilitate patient handoff and sign-out, as well as to link charge capture with quality measures. Cutting-edge organizations are looking to create actionable information for clinicians through software that can analyze data, track patients'progress, and send out alerts when conditions worsen.

User Experience of Mobile Personal Health Records for the Emergency Department: Mixed Methods Study.

BACKGROUND: Personal health records (PHRs) can be useful in the emergency department, as they provide patient information in an accurate and timely manner and enable it to be used actively. This has an effect on patients' health outcomes and patient experience. Despite the importance of PHRs in emergencies, there are only a few studies related to PHRs in emergencies that evaluate patient experience. OBJECTIVE: This study aims to introduce the novel mobile PHR (mPHR) platform to emergency environments and assess user experience. METHODS: The study was conducted from October 2019 to November 2019. In total, 1000 patients or carers in the emergency departments of 3 hospitals were provided an application-based service called FirstER, which was developed to collect and utilize medical information for patients in the emergency department. This study was performed as a mixed methods study. After using FirstER, we investigated its usability and conducted a survey on the experience of obtaining medical information with a legacy system and with FirstER. Additionally, we interviewed 24 patients to gain insight into their experiences regarding medical information using FirstER. For the quantitative analysis, the survey results were analyzed using descriptive statistics (mean and standard deviation). For the qualitative analysis, we determined the keywords and their frequencies from each survey question and interview question. RESULTS: In total, 1000 participants, consisting of both patients and carers, were recruited in this study. Their mean age was 41.4 (SD 13.3) years. We ascertained participants' satisfaction with FirstER and their mPHR needs through a survey and an in-depth interview. With the current system, participants were not well aware of their health conditions and medical information, and they were passive in the use of their medical information and treatment. However, they wanted their medical information for several reasons, such as information sharing and managing their health conditions. FirstER provided participants with their needed information and an easy way to access it. The mean System Usability Scale (SUS) value was 67.1 (SD 13.8), which was considered very near to acceptable. CONCLUSIONS: This study is the first to implement mPHRs in the emergency department of large tertiary hospitals in the Republic of Korea. FirstER was found to enhance user experience in emergencies, as it provided necessary medical information and proper user experience. Moreover, the average SUS was 67.1, which means that participants found FirstER to be very near to acceptable. This is very encouraging in that FirstER was developed within a very short time, and it was a pilot study. TRIAL REGISTRATION: Clinicaltrials.gov NCT04180618; https://clinicaltrials.gov/ct2/show/NCT04180618.

USB drives for communication of medical information in a pediatric dialysis unit.

We evaluated the feasibility of using universal serial bus (USB) drives for communicating medical information between parents of children receiving dialysis and medical personnel during clinical encounters. When surveyed, parents and pediatric resident physicians supported the use of USB drives and were willing to use the devices. The utilization rate of USB drives was 57%.

Haemoassist--a hand-held electronic patient diary for haemophilia home care.

On-demand or prophylactic home-treatment is currently the treatment of choice for haemophilia patients. To allow physicians to monitor the amount of factor concentrates administered, the patients document each factor injection in a paper-diary. Nevertheless, because of the fact that most patients visit their physicians only two to four times a year, there could be considerable delay in detecting medication problems. The aim of this pilot study was to assess whether an electronic documentation tool could successfully replace traditional paper-diaries for haemophilia A patients and enable the physician to have a timely overview of the patient's treatment. An electronic, hand-held documentation tool, Haemoassist, was developed. In this study, patients using prophylaxis and on-demand therapies documented their factor consumption both electronically and on paper-diaries. Documentations were compared and descriptively evaluated. Patients also completed a survey to evaluate the feasibility and gather their opinions on the Haemoassist system. Ten patients from two haemophilia treatment centres in Germany submitted a total of 548 records via hand-held device during the observation period, from March 2006 to February 2007. Comparison of electronic and paper-based records showed differing responses among patients with some patients entering more electronic and some others more paper-based documentations. In the questionnaires on feasibility and usefulness of Haemoassist, three patients preferred the electronic tool, two patients wanted to continue using paper-based diaries, and one had no preference. The study shows that an electronic documentation system is feasible for haemophilia patients and provides the physician with the opportunity to more closely monitor patients. However, not all patients seem to be qualified for using an electronic tool, and the tool has to run reliably without major errors for ensuring reliability and acceptability. In the future, Haemoassist might support quality assurance in haemophilia treatment and improve guidance in the home-care setting.

The South London and Maudsley NHS Foundation Trust Biomedical Research Centre (SLAM BRC) case register: development and descriptive data.

BACKGROUND: Case registers have been used extensively in mental health research. Recent developments in electronic medical records, and in computer software to search and analyse these in anonymised format, have the potential to revolutionise this research tool. METHODS: We describe the development of the South London and Maudsley NHS Foundation Trust (SLAM) Biomedical Research Centre (BRC) Case Register Interactive Search tool (CRIS) which allows research-accessible datasets to be derived from SLAM, the largest provider of secondary mental healthcare in Europe. All clinical data, including free text, are available for analysis in the form of anonymised datasets. Development involved both the building of the system and setting in place the necessary security (with both functional and procedural elements). RESULTS: Descriptive data are presented for the Register database as of October 2008. The database at that point included 122,440 cases, 35,396 of whom were receiving active case management under the Care Programme Approach. In terms of gender and ethnicity, the database was reasonably representative of the source population. The most common assigned primary diagnoses were within the ICD mood disorders (n = 12,756) category followed by schizophrenia and related disorders (8158), substance misuse (7749), neuroses (7105) and organic disorders (6414). CONCLUSION: The SLAM BRC Case Register represents a 'new generation' of this research design, built on a long-running system of fully electronic clinical records and allowing in-depth secondary analysis of both numerical, string and free text data, whilst preserving anonymity through technical and procedural safeguards.
