Supporting the Early Detection of Disease Onset and Change Using Document Vector Analysis of Nursing Observation Records.

Nursing records are an account of patient condition and treatment during their hospital stay. In this study, we developed a system that can automatically analyze nursing records to predict the occurrence of diseases and incidents (e.g.

Secondary use of hospital information system data for safe bedside radiography in terms of patient factors.

Objective:: The purpose of this study was to use patient data gathered by a hospital information system (HIS) to improve the safe performance of bedside radiography.

Method:: Hierarchical cluster analysis was used to investigate the factors of hospitalised patients who had undergone radiography in the X-ray room or at the bedside. Logistic regression analysis was then performed to quantify patient factors and calculate the probability of undergoing general radiography or bedside radiography.

Development of an electronic instruction system to promote multidisciplinary teams.

While the provision of medical care incorporating safety measures, etc. that can earn the trust of the people, patients in particular, is required, the content of instruction is diverse, complex and rapidly increasing in volume along with the sophistication and specialization of medical care. However, until now, the development of electronic instruction systems has lagged behind in the development of HIS.

DPC in acute-phase inpatient hospital care. Visualization of amount of nursing care provided and accessibility to nursing care.

Objective: The purpose of this study was to improve accessibility to nursing care by clarifying the relationship between patient characteristics and the amount of nursing care for the Diagnosis Procedure Combination system (DPC).

Method: The subjects included 528 lung cancer patients; 170 gastric cancer patients; and 91 colon cancer patients, who were hospitalized from July 1, 2008, to March 31, 2010, at a university hospital. The patients were categorized into groups according to factors that could affect the amount of nursing care.

Development of the electronic patient record system based on problem oriented system.

In Japan, POS (problem oriented system) is recommended in the clinical guideline. Therefore, the records are mainly made by SOAP. We developed a system mainly with a function which enabled our staff members of all kinds of professions including doctors to enter the patients' clinical information as an identical record, regardless if they were outpatients or inpatients, and to observe the contents chronologically.

[Image examination of malignant tumors in lungs observed on the basis of cost analysis using diagnosis procedure combination data].

Recently, the environment of medical treatment in our country has become more strict. The purpose of this study is to find changes in the implementation of diagnostic imaging from the point of view of cost analysis, through the use of diagnosis procedure combination (DPC) data. The patient data has been extracted from the DPC data.

Examination of nursing dependency for admission fee and measurement of nurses' work load for nursing care.

In April 2006, a system called seven-to-one nursing system was newly introduced in acute medicine which requires intense nursing care. In April 2008, a survey was conducted using "Assessment Sheet regarding Severity of Disease / Degree of Necessity of Nursing Care at General Wards", and obligation was established to fulfill certain requirements in medical institutions which collect the basic admission charge for the seven-to-one system. This survey is not a tool developed to investigate the amount of care required for patients but to measure the standard for the facility level.

Development of hospital data warehouse for cost analysis of DPC based on medical costs.

Objectives: To develop a data warehouse system for cost analysis, based on the categories of the diagnosis procedure combination (DPC) system, in which medical costs were estimated by DPC category and factors influencing the balance between costs and fees.

Methods: We developed a data warehouse system for cost analysis using data from the hospital central data warehouse system. The balance data of patients who were discharged from Kagoshima University Hospital from April 2003 to March 2005 were determined in terms of medical procedure, cost per day and patient admission in order to conduct a drill-down analysis.

Study on weighting of amount of nursing care using data on index of patient's need for nursing.

We have creatively categorized the classification of index of patient's need for nursing to collect ever-objective data on the index of patient's need for nursing and utilized it as an indicator to evaluate the amount of nursing care necessary for patients. We also weighted the index of patient's need for nursing and categorized it into categories A, B and C based on the accumulated data on the index of patient's need for nursing, and calculated the cost of nursing care by adding the nurse salary data to the weighting. Moreover, we developed a system in which measurement of amount of nursing care based on the data on the index of patient's need for nursing and calculation of nursing care cost could be done by utilizing the hospital Data Warehouse.

Study on weighting of amount of nursing care using data on index of patient's need for nursing and system approach.

The importance of appropriate staffing of nurses has been emphasized and optimal provision of nursing care has increased in order to improve the quality of nursing service. Since the introduction of the nursing information system in 1987, we have creatively categorized the classification of index of patient's need for nursing to collect ever-objective data on the index of patient's need for nursing and utilized it as an indicator to evaluate the amount of nursing care necessary for patients. We also weighted the index of patient's need for nursing and categorized it into categories A, B, and C based on the accumulated data on the index of patient's need for nursing, and calculated the cost of nursing care by adding the nurse salary data to the weighting.

Status and perspective of hospital information systems in Japan.

Questionnaire surveys were sent to hospital managers, designed to shape the policy for future hospital information systems in Japan. The answers show that many hospitals use dedicated management systems, especially for patient registration and accounting, and personnel, food control, pharmacy and financial departments. In many hospitals, order-entry systems for laboratory tests and prescriptions are well developed.

[Construction of an MRI reporting system using the Internet].

Out university hospital, includes a LAN (Local Area Network) and uses network services such as WWW(World Wide Web). We have constructed an MRI diagnostic reporting system on the Internet in which interactive date management was established on WWW by using CGI (Common Gateway Interface) software. Linking database information such as MRI reports with WWW browsers using by CGI provides easy data access to the database and offers hypertext and searching.

Soluble intercellular adhesion molecule-1 in serum in chronic hepatitis B and C.

Intercellular adhesion molecule-1 (ICAM-1) is expressed on the hepatocyte membrane in patients with chronic hepatitis B and C. We assayed levels of the soluble form of this molecule (sICAM-1) in serum by an enzyme-linked immunosorbent assay method; we then analyzed the results in relation to hepatitis activity. Fifty-one patients with chronic hepatitis (22 with type B and 29 with type C) and 10 normal controls were examined.

Development of total medical material distribution management system.

Since September 1992, attempts have been made at Kagoshima University Hospital to develop the Medical Material Distribution Management System which helps to realize optimal hospital management as a subsystem of the Total Hospital Information System of Kagoshima University (THINK). As this system has been established, it has become possible for us to have an accurate grasp of the flow and stock of medical materials at our hospital. Furthermore, since September 1993, the Medical Material Distribution Management System has been improved and the Total Medical Material Distribution Management System has been smoothly introduced into the site of clinical practice.

A case report of drug-induced allergic hepatitis probably due to the N-methyltetrazolethiol group cephalosporin.

Drug-induced allergic hepatitis occurred in a patient being treated with cefpiramide sodium. A lymphocyte blast transformation test suggested that the N-methyltetrazolethiol group of the drug was responsible for the induction of acute hepatitis. A detailed case report and discussion of the relevant literature are presented in this paper.

Hepatitis C virus plus- and minus- strand RNA in hepatocellular carcinoma and adjoining nontumorous liver.

The presence of hepatitis C virus (HCV) RNA in serum and liver tissue was examined in seven patients with hepatocellular carcinoma (HCC), using the reverse transcriptase-polymerase chain reaction method with primers for the 5'-noncoding region. Plus-strand HCV-RNA was detected in the serum and liver tissue (both cancerous and noncancerous tissue) of all five patients who were positive for anti-HCV antibodies (C100-3 and P22) and was not detected in both of two patients who were negative for anti-HCV antibodies. Minus-strand HCV-RNA was only detected in the liver tissue (cancerous and noncancerous portion) of the five anti-HCV antibody-positive patients.

[Detection of minus strand HCV RNA in liver tissue by reverse transcriptase polymerase chain reaction (RT-PCR)].

Hepatitis C virus RNA in serum and liver tissue was examined in seven patients with liver cirrhosis by reverse transcriptase polymerase chain reaction method using primers for 5'-non-coding region. Plus strand HCV RNA were detected in serum and liver tissues in five of five patients who had HCV antibodies (C100-3 antibody and P22 antibody) and were not detected in two of two patients who do not have HCV antibody. Minus strand HCV RNA was detected in liver tissue of five HCV antibody positive patients.

Development of a hospital management system to analyze nursing information using a microcomputer.

We have developed a hospital management system to analyze the large amount of the nursing information using a microcomputer system. In this system, we have combined the information from the patient database and the nursing database in order to evaluate the quality of medical care in the hospital. The utilization of a microcomputer is useful for filing and analyzing it and presenting the results in a variety of formats, including graphic representations.

The management of medical records.

An optical disk filing system is an efficient approach to storing medical records; however, this system has not yet been put to practical use because it is usually a "stand-alone" type indirectly connected to a hospital information system. We have developed a medical record management system with an optical disk filing system connected to the host computer in the hospital information system. We can retrieve and display the medical records through the CRT (Cathode Ray Tube) terminals of the hospital information system at every ward and outpatient clinic.

[Significance of anti-HTLV-I antibody in cerebrospinal fluid in diagnosis of HTLV-I associated myelopathy (HAM)].

Anti-HTLV-I antibody was measured in 69 cerebrospinal fluids (CSFs) of cases with typical HTLV-I associated myelopathy (HAM) and other disorders whose symptoms were similar to HAM in order to evaluate the diagnostic significance of anti-HTLV-I antibody in CSF. Both gelatin particle agglutination (PA; Serodia-ATLA) method and recombinant gag-env hybrid protein coated ELISA were employed simultaneously. Antibody titers of both methods showed linear correlation.

The seroepidemiology of hepatitis A and B in a Japanese town.

Sera collected from 1,118 healthy children and adults aged between four years and 90 years during the period 1989 to 1990, were tested for serological markers of hepatitis A virus (HAV) [antibody to HAV (anti-HAV)] and hepatitis B virus (HBV) [hepatitis B surface antigen (HBsAg) and antibody to hepatitis B surface antigen (anti-HBsAb)]. The overall prevalence rates of anti-HAV, HBsAg, and anti-HBV were 20.2%, 0.
