Quality Requirements for Electronic Health Record Systems*. A Japanese-German Information Management Perspective.

BACKGROUND: For more than 30 years, there has been close cooperation between Japanese and German scientists with regard to information systems in health care. Collaboration has been formalized by an agreement between the respective scientific associations. Following this agreement, two joint workshops took place to explore the similarities and differences of electronic health record systems (EHRS) against the background of the two national healthcare systems that share many commonalities. OBJECTIVES: To establish a framework and requirements for the quality of EHRS that may also serve as a basis for comparing different EHRS. METHODS: Donabedian's three dimensions of quality of medical care were adapted to the outcome, process, and structural quality of EHRS and their management. These quality dimensions were proposed before the first workshop of EHRS experts and enriched during the discussions. RESULTS: The Quality Requirements Framework of EHRS (QRF-EHRS) was defined and complemented by requirements for high quality EHRS. The framework integrates three quality dimensions (outcome, process, and structural quality), three layers of information systems (processes and data, applications, and physical tools) and three dimensions of information management (strategic, tactical, and operational information management). CONCLUSIONS: Describing and comparing the quality of EHRS is in fact a multidimensional problem as given by the QRF-EHRS framework. This framework will be utilized to compare Japanese and German EHRS, notably those that were presented at the second workshop.

A system for health promotion using tele-homecare technology in community.

We have developed a system for health promotion of regional inhabitants, using CATV network at Tsushima Island in Nagasaki, Japan from 2010 to 2012. This system was provided by five kinds of services such as safety confirmation system, monitoring system of vital signs, sharing system for healthcare information, supervised administration system (compliance check of medicines), and local community TV program. Based on this experience we have been challenging a new trial at Kinkai district in Nagasaki which is aimed to be sustainable and helpful servicesboth for patients and staffs.

Relationship between asynchronous myocardial contraction and left ventricular systolic and diastolic function--assessment using the ECG-gated polar map with 99mTc-methoxy-isobutyl isonitrile.

BACKGROUND: To quantitate the degree of 3-dimensional asynchronous myocardial contraction, an ECG-gated polar map method was developed with (99m)Tc-methoxy-isobutyl isonitrile, and used to investigate the relationship between asynchrony and left ventricular (LV) function. METHODS AND RESULTS: Twelve normal subjects and 38 patients with an old myocardial infarction were studied with ECG-gated single-photon emission computed tomography (SPECT). In each frame, a myocardial perfusion polar map was reconstructed and the peak contraction phase in each pixel was displayed (phase map). The degree of asynchronous contraction was assessed from the standard deviations of the peak contraction phase (SDP) on the phase map. Ejection fraction (EF), peak ejection rate (PER), 1/3EF, peak filling rate (PFR) and 1/3 filling fraction (1/3FF) were calculated by the quantitative gated SPECT software, and E/A from Doppler echocardiography. The SDP was compared with these parameters. Correlation coefficients and p values between the SDP and parameters of cardiac function were as follows: EF, r=-0.69 (p<0.001); PER, r=-0.54 (p<0.001); 1/3EF, r=-0.57 (p<0.001); PFR, r=-0.29 (p<0.05); 1/3FF, r=-0.63 (p<0.001); E/A, r=-0.11 (p=0.51). CONCLUSIONS: There was a negative correlation between the SDP and LV systolic and diastolic function, which confirmed the functional significance of asynchrony on cardiac function.
