Electronic data management systems using computer network systems and client/server architecture are increasingly used in laboratories and transfusion services. Severe problems arise if there is no network access to the database server and critical functions are not available. We describe a manual backup system (MBS) developed to maintain the delivery of blood products to patients in a hospital transfusion service in case of a computer network breakdown. All data are kept on a central SQL database connected to peripheral workstations in a local area network (LAN). Request entry from wards is performed via machine-readable request forms containing self-adhesive specimen labels with barcodes for test tubes. Data entry occurs on-line by bidirectional automated systems or off-line manually. One of the workstations in the laboratory contains a second SQL database which is frequently and incrementally updated. This workstation is run as a stand-alone, read-only database if the central SQL database is not available. In case of a network breakdown, the time-graded MBS is launched. Patient data, requesting ward and ordered tests/requests, are photocopied through a template from the request forms on special MBS worksheets serving as laboratory journal for manual processing and result report (a copy is left in the laboratory). As soon as the network is running again the data from the off-line period are entered into the primary SQL server. The MBS was successfully used at several occasions. The documentation of a 90-min breakdown period is presented in detail. Additional work resulted from the copy work and the belated manual data entry after restoration of the system. There was no delay in issue of blood products or result reporting. The backup system described has been proven to be simple, quick and safe to maintain urgent blood supply and distribution of laboratory results in case of unexpected network breakdown. 相似文献

AbstractHemoglobin A1c (HbA1c) is a long-term measure for glucose concentration in plasma. Since its introduction as a diabetes monitoring tool, and its more recent application as a diagnostic tool, the number of measurements of HbA1c have risen dramatically. However, HbA1c change is slow, so repeating measurements should not be done too often. We use a large, unfiltered dataset from 52,017 patients to determine the possible rate of change in HbA1c concentration. In our laboratory, the critical difference between HbA1c measurements is 8.5%. Our data show that a 1-unit HbA1c rise takes 4 weeks to occur, hence, at a HbA1c concentration around 50?mmol/mol Hgb, a critically increased HbA1c concentration cannot be determined until after 16 weeks. Conversely a critically lower HbA1c can manifest itself after 2 weeks, but after 7 weeks the dropping tendency stops. The amount of measurements that can be cancelled because they were taken sooner than 16 weeks is 23 percent. 相似文献

Background Appropriate documentation of critical care services, including key time-based parameters, is critical to accurate severity of illness metrics and proper reimbursement. Documentation of time-based elements for critical care services performed in emergency departments (ED) remains inconsistent. We integrated electronic medical record and real-time location system (RTLS)-derived data to augment quality improvement methodology. Objective We aimed to increase the proportion of patient encounters with critical care services performed at a pediatric ED that had appropriate documentation from a baseline of 76 to 90% within 6 weeks. Methods The team formulated a framework of improvement and performed multiple plan-do-study-act cycles focused on key drivers. We integrated the capabilities of an RTLS for precise location tracking to identify patient encounters in which critical care services were performed and to minimize unnecessary audits and feedback. We developed an intervention using iterative revisions to address key drivers and improve documentation. The primary outcome was the proportion of patient encounters for which critical care services were performed for which a time-based attestation was documented in the medical record. Results We analyzed 92 encounters between March 2020 and April 2020. While the proportion of eligible patient encounters with critical care documentation improved from 76 to 85%, this change was unable to be directly attributed to improvement efforts. Patients with respiratory complaints encompassed the majority of eligible encounters without appropriate documentation. Conclusion Utilizing improvement methodology and a novel application of RTLS, we successfully identified the co-location of physicians with patients receiving critical care services and designed interventions to improve documentation of critical care services provided in a pediatric ED. While changes were not able to be attributed to improvement efforts in this project, this project demonstrates the utility of RTLS to augment and inform systematic improvement efforts. 相似文献

Introduction: Patient Data Management Systems (PDMS) for ICUs collect, present and store clinical data. Various intentions
make analysis of those digitally stored data desirable, such as quality control or scientific purposes. The aim of the Intensive
Care Data Evaluation project (ICDEV), was to provide a database tool for the analysis of data recorded at various ICUs at
the University Clinics of Vienna.Settings: General Hospital of Vienna, with two different PDMSs used: Care Vue 9000 (Hewlett Packard, Andover, USA) at two ICUs (one
medical ICU and one neonatal ICU) and PICIS Chart+ (PICIS, Paris, France) at one Cardiothoracic ICU.Concept and methods: Clinically oriented analysis of the data collected in a PDMS at an ICU was the beginning of the development. After defining
the database structure we established a client-server based database system under Microsoft Windows NITM and developed a user friendly data quering application using Microsoft Visual C++TM and Visual BasicTM;Results: ICDEV was successfully installed at three different ICUs, adjustment to the different PDMS configurations were done within
a few days. The database structure developed by us enables a powerful query concept representing an ‘EXPERT QUESTION COMPILER’
which may help to answer almost any clinical questions. Several program modules facilitate queries at the patient, group and
unit level. Results from ICDEV-queries are automatically transferred to Microsoft ExcelTM, for display (in form of configurable tables and graphs) and further processing.Conclusions: The ICDEV concept is configurable for adjustment to different intensive care information systems and can be use to support
computerized quality control. However, as long as there exists no sufficient artifact recognition or data validation software
for automatically recorded patient data, the reliability of these data and their usage for computer assisted quality control
remain unclear and should be further studied.

As the issue of data overload is a problem in critical care today, it is of utmost importance to improve acquisition, storage, integration, and presentation of medical data, which appears only feasible with the help of bedside computers.The data originates from four major sources: (1) the bedside medical devices, (2) the local area network (LAN) of the ICU, (3) the hospital information system (HIS) and (4) manual input. All sources differ markedly in quality and quantity of data and in the demands of the interfaces between source of data and patient database.The demands for data acquisition from bedside medical devices, ICU-LAN and HIS concentrate on technical problems, such as computational power, storage capacity, real-time processing, interfacing with different devices and networks and the unmistakable assignment of data to the individual patient.The main problem of manual data acquisition is the definition and configuration of the user interface that must allow the inexperienced user to interact with the computer intuitively. Emphasis must be put on the construction of a pleasant, logical and easy-to-handle graphical user interface (GUI). Short response times will require high graphical processing capacity. Moreover, high computational resources are necessary in the future for additional interfacing devices such as speech recognition and 3D-GUI.Therefore, in an ICU environment the demands for computational power are enrmous. These problems are complicated by the urgent need for friendly and easy-to-handle user interfaces. Both facts place ICU bedside computing at the vanguard of present and future workstation development leaving no room for solutions based on traditional concepts of personal computers.For a truely paperless documentation a new integrated computational paradigm has to be developed that might required a new dimension of computational and graphical power at the bedside. 相似文献

Using an interactive voice response system to improve patient safety following hospital discharge 总被引:2,自引:0,他引:2
BACKGROUND: Patients often experience complications when transitioning from hospital to home. These complications are frequently related to poor monitoring. An interactive voice response system (IVRS) could improve post-discharge monitoring. OBJECTIVE: To determine the feasibility and utility of an IVRS to monitor patients following hospital discharge. DESIGN: Prospective cohort study at an academic health sciences centre. PATIENTS: Consecutive internal medicine patients who had a touch-tone telephone, spoke English, had no cognitive impairments and were discharged home. MEASUREMENTS: Feasibility was defined as the proportion of patients reached by the IVRS and the proportion completing an IVRS-based survey. Utility was defined as the percentage of patients whose outcomes could have been changed by the IVRS. METHODS: We programmed the IVRS to call patients and administer a simple survey 48 hours after discharge. The survey's objective was to identify all patients with new health problems. Such patients were telephoned by a nurse to clarify and address the problem. RESULTS: We enrolled 77 patients who were predominantly male (68%), elderly (median age 65 years) and chronically ill (median number of co-morbidities = 3). The IVRS reached 45 of the 77 patients (58.4%). Forty patients (51.9%) answered all questions on the survey. Twenty patients (26%, 95% CI 17%-37%) indicated new or worsening symptoms, problems with their medications, or requested to talk to the clinic nurse. For 10 patients (13%, 95% CI 7%-22%), the IVRS could have made a difference in their outcome. CONCLUSION: Using an IVRS, we were able to identify several important new health concerns arising following hospital discharge. Subtle changes could increase the feasibility and utility of IVRS technology in improving post-discharge outcomes. 相似文献
