Black Sea tele-diab: development and implementation of an electronic patient record for patients with diabetes

Black Sea tele-diab (BSTD) is a three-year European Union (EU)-funded International Collaboration (INCO) Telematics Application Project to develop a standardized software package (in the national languages of the partners) for the storage and transfer of medical information collected from patients with diabetes. The software utilizes an electronic medical record architecture based on the Good European Health Record, developed within the Advanced Informatics in Medicine programme. Software development is being carried out by the partners in Eastern Europe, which will help promote the development of medical informatics and communication technologies among countries of Central Europe (CCE) and newly independent states (NIS) countries. The diabetes data set is based on the WHO Europe DiabCare Basic Information Sheet; the project therefore supports the World Health Organisation (WHO) Quality Care Programme for monitoring the prevalence and incidence of diabetic complications across Europe. Diabetes is used as a model, as standards for data collection and clinical care are well developed and the concepts applied and learnt in diabetes will be generally applicable to other chronic diseases and medical disciplines.

Core Standards of the EUBIROD Project. Defining a European Diabetes Data Dictionary for Clinical Audit and Healthcare Delivery

BACKGROUND

A set of core diabetes indicators were identified in a clinical review of current evidence for the EUBIROD project. In order to allow accurate comparisons of diabetes indicators, a standardised currency for data storage and aggregation was required. We aimed to define a robust European data dictionary with appropriate clinical definitions that can be used to analyse diabetes outcomes and provide the foundation for data collection from existing electronic health records for diabetes.

METHODS

Existing clinical datasets used by 15 partner institutions across Europe were collated and common data items analysed for consistency in terms of recording, data definition and units of measurement. Where necessary, data mappings and algorithms were specified in order to allow partners to meet the standard definitions. A series of descriptive elements were created to document metadata for each data item, including recording, consistency, completeness and quality.

RESULTS

While datasets varied in terms of consistency, it was possible to create a common standard that could be used by all. The minimum dataset defined 53 data items that were classified according to their feasibility and validity. Mappings and standardised definitions were used to create an electronic directory for diabetes care, providing the foundation for the EUBIROD data analysis repository, also used to implement the diabetes registry and model of care for Cyprus.

CONCLUSIONS

The development of data dictionaries and standards can be used to improve the quality and comparability of health information. A data dictionary has been developed to be compatible with other existing data sources for diabetes, within and beyond Europe.

Privacy impact assessment in the design of transnational public health information systems: the BIRO project

OBJECTIVES

To foster the development of a privacy-protective, sustainable cross-border information system in the framework of a European public health project.

MATERIALS AND METHODS

A targeted privacy impact assessment was implemented to identify the best architecture for a European information system for diabetes directly tapping into clinical registries. Four steps were used to provide input to software designers and developers: a structured literature search, analysis of data flow scenarios or options, creation of an ad hoc questionnaire and conduction of a Delphi procedure.

RESULTS

The literature search identified a core set of relevant papers on privacy (n = 11). Technicians envisaged three candidate system architectures, with associated data flows, to source an information flow questionnaire that was submitted to the Delphi panel for the selection of the best architecture. A detailed scheme envisaging an "aggregation by group of patients" was finally chosen, based upon the exchange of finely tuned summary tables.

CONCLUSIONS

Public health information systems should be carefully engineered only after a clear strategy for privacy protection has been planned, to avoid breaching current regulations and future concerns and to optimise the development of statistical routines. The BIRO (Best Information Through Regional Outcomes) project delivers a specific method of privacy impact assessment that can be conveniently used in similar situations across Europe.

A networked electronic patient record system for diabetes

This paper describes the development and clinical implementation of the SincroDiab--a synchronized diabetes register for the routine clinical practice in a LAN and for design of long-term trials and epidemiological studies based on the GEHR (Good European Health Record) architecture. The objectives of the SincroDiab system were to address the need to establish a more efficient and more effective information infrastructure to improve the ability to share patient record information among health care providers, to reduce the health care delivery costs, to meet the requirements of legal, regulatory or accreditation standards, to share comparable patients data among different sites within a multi-entity health care delivery system and to improve quality of care by network connecting the data repository to clinical workstations and departmental systems.

The Black Sea Tele-Diab System: development-implementation-clinical evaluation

This paper describes the application of the GEHR (Good European Health Record) architecture to develop a system to enable the storage and exchange of EHCRs (Electronic Health Care Record) of patients with diabetes, in the Black Sea area. The objectives of the Black Sea Tele Diab System (BSTD) were to develop and evaluate the use of a fully-computerised healthcare record system in a clinical setting, to promote the use of electronic data exchange of healthcare information and to provide a framework for the epidemiological study and monitoring of diabetes care.

The pattern of the electrodermal activity as indicator of stress related reaction

The aim of the present study was to characterize the patterns of signals associated with noninvasively detected skin sudomotor transient reflexes in a group of 221 apparently healthy people, aged between 16 and 72 years. By means of two pairs of surface electrodes applied respectively to the palm of the hand and to the sole of the foot skin impedance changes were recorded as two electrodermal parameters: skin electrical resistance and skin electrical capacitance. The recordings were obtained under standard conditions initially in the basal resting state of the subject and then, after the application of some standardized stimuli (evoked electrodermal responses). In terms of the basal (spontaneous) electrodermal activity and the evoked responses the subjects were divided into three categories: I--those with a high threshold of sympathetic activation (quiet basal trace and ample evoked responses); II--those with a medium threshold for sympathetic activation (basal trace with some spontaneous electrodermal activity, but obviously of a lower amplitude than the evoked responses); III--those with a low threshold for sympathetic activation (a tracing showing frequent, larger spontaneous sympathetic discharges from which the evoked responses cannot be distinguished). Of the 221 subjects, 22.2% in group I, 69.2% were included in group II, and 8.6% in group III. Our data show that each individual presents a characteristic electrodermal pattern which expresses the degree of stability/instability of the sympathetic nervous system, the most sensitive component of the physiological stress reaction system.

Peripheral sympathetic neuropathy evaluated by recording the evoked electrodermal response using an impedance reactometer

Autonomic nervous dysfunction was indirectly evaluated on the basis of the skin electrical resistance relative variation (SERV), recorded by our recently developed system, with two pairs of surface electrodes placed on the palm and on the sole of the foot, after the application to the subject of a sensory stimulus (sound 60 dB, 860 Hz, 0.5 s duration) or in the course of a Valsalva manoeuvre. The results were digitally measured and recorded on thermosensitive millimetric paper analysing the following parameters: latency (LT), i.e. the time interval(s) between application of the stimulus and onset of SERV, both at palm (LTh) and foot (LTf); amplitude of the response (mm) recorded and evaluated in the form of SERV; velocity of the response as rate of time change (Vr) and autonomic conduction velocity, -ACV (m/s), calculated by the height/LT ratio. The present study refers to a group of 60 diabetic patients: 32 F/28 M; mean age +/- SD 46.8 +/- 11.8 years; 29 insulin-dependent, 21 non-insulin-dependent; duration of diabetes 8.6 +/- 4.6 years. The data were compared to those recorded in a group of 50 nondiabetics (22 F/28 M; mean age 47.5 +/- 14.1 years) who were apparently healthy. A significant statistical difference (P less than 0.001) was found between diabetic patients and controls for all studied parameters: LTh (s) 2.65 +/- 1.2 vs. 1.91 +/- 0.6; LTf(s) 3.6 +/- 1.4 vs. 2.6 +/- 0.7; SERV (mm) 7.5 +/- 4.8 vs. 18.5 +/- 6.6; Vr (mm) 4.4 +/- 2.1 vs. 13.5 +/- 5.3; ACT (m/s) 0.41 +/- 0.23 vs. 0.97 +/- 0.18.(ABSTRACT TRUNCATED AT 250 WORDS)

Quantitative noninvasive electrophysiological evaluation of the activity of the cutaneous division of the sympathetic nervous system

The functional status of the cutaneous division of the orthosympathetic nervous system was indirectly and non-invasively assessed by monitoring the skin electrical relative resistance variations (SERV). The advantages of our recording system of second generation were (1) simultaneous recording on two or four channels of the evoked electrodermal response to psychic or to sensorial stimulus; (2) self-balancing system which allows the recording of the relative variation of the electric parameter, i.e. its variation with time; (3) precise determination of the amplitude (omega/s, mu F/s) of the evoked response; (4) reference of the latency time (LT) of the evoked response to the length of the anatomical pathway of the signal giving the autonomic conduction velocity (ACV). Decrease in diabetic autonomic neuropathy of both spontaneous and evoked electrodermal activities suggested their relationship with cutaneous sympathetic activity.
