Analysis of dispensing activities before and after decentralization of pharmaceutical services.

Changes in drug handling activities, revenue, and telephone communications were documented during a conversion from a centralized unit dose system to decentralized pharmacists and unit dose services in a 310-bed university teaching hospital. All decentralized services were mobile; no physical satellites were utilized. Computer programs were used to collect and analyze drug handling and revenue data during a prestudy control period and three equal-length study periods after decentralization of pharmaceutical services for five patient care areas of the hospital. All telephone calls to the central pharmacy were recorded and classified by type during 21 days of the prestudy period and were compared with 21 days of the second postimplementation period. The mean number of doses handled decreased for all patient care areas. After decentralization the number of telephone calls to the central pharmacy requesting clinical drug information, as well as distributive information, decreased sharply. Moving the pharmacist to the patient care unit decreased the time that pharmacists spent handling drugs and improved communication with the medical and nursing staffs.

[Evaluation of the Rotterdam guideline for referral in case of chronic hepatitis B: improvement possible via a shortening of the referral chain and better distribution of information].

OBJECTIVE: Evaluation of the Rotterdam guideline for referring patients with chronic hepatitis B virus (HBV) infections from primary to specialist care for diagnosis and treatment. DESIGN: Retrospective. METHOD: Whether or not the guideline was followed correctly was determined in patients with chronic hepatitis B who were reported to the Municipal Health Service (GGD) in Rotterdam in 1998 and 1999. This was done by a study of their files and by questioning their general practitioners by phone. RESULTS: During the study period, 376 cases of chronic hepatitis B were seen at the GGD; 32% of the patients dropped out during the referral trajectory. Drop-out took place at three different times: 13% during the process of deciding whether the patient should be referred according to the guideline, 12% during the consultation period at the GGD, and 7% after consultation at the GGD and before first contact with a specialist (via referral from the general practitioner). The reasons for dropping out were either procedural factors, such as missing information in the patient file and unclear management by the GGD, and personal factors such as failure of the general practitioner or the patient to comply with the recommendations. CONCLUSION: The guideline for the referral of chronic hepatitis B patients functioned well but implementation can be improved, since some patients did not reach the specialist. Improvement would be made possible by shortening the referral chain and by giving more information to patients and general practitioners about hepatitis B and its potential consequences.

Crossing heterogeneous information sources for better analysis of health and social care data.

In this paper we describe a methodology that emerged during an implementation of a health-and-social-care-oriented data repository, which consists in grouping information from heterogeneous and distributed information sources. We developed this methodology by first constructing a concrete data repository, containing information about elderly patients flows in the UK's long-term care (LTC) system. In our specific case, the role of the data repository is to allow knowledge extraction about consumption and behavioural tendencies in the elderly people population within the LTC system. These tendencies can be depicted in terms of survival behaviour (modelling), cost evolution, and bed use. Other types of knowledge that can be extracted are typical patient profiles, placement policy in term of rules and criteria effectively applied and, specific features of the business process behind the long-term care provision. A well-constructed data repository can support the discovery (analysis) of hidden aspects about the way patients are placed and accepted in the LTC, and also how the allocated resources are consumed. We argue that the use of this methodology could save time in similar undertakings or in other fields than health and social care.

Semantic integration in healthcare networks.

A seamless support of information flow for increasingly distributed healthcare processes requires to integrate heterogeneous IT systems into a comprehensive distributed information system. Different standards contribute to ease this integration. In a research project focussing on the development of a reference architecture for inter-institutional health information systems, we identified and categorised concurring integration standards by distinguishing between technical and semantic integration on the one hand, and data and functional integration on the other hand. In addition, standards for semantic integration are roughly categorised according to their scope. By placing standards into a corresponding matrix a "semantic gap" is revealed, which cannot be covered by standards as it contains volatile medical concepts. As a conclusion, it is recommended to conceptually consider the necessity of system evolution in systems architectures and also in future integration standards.

Integrated multimedia medical data agent in E-health.

E-Health is producing a great impact in the field of information distribution of the health services to the intra-hospital and the public. Previous researches have addressed the development of system architectures in the aim of integrating the distributed and heterogeneous medical information systems. The easing of difficulties in the sharing and management of medical data and the timely accessibility to these data is a critical need for health care providers. We have proposed a client-server agent that allows a portal to the every permitted Information System of the Hospital that consists of PACS, RIS and HIS via the Intranet and the Internet. Our proposed agent enables remote access into the usually closed information system of the hospital and a server that indexes all the medical data which allows for in-depth and complex search queries for data retrieval.

Implementing network security guidelines in health care information systems.

A Health Care Establishment (HCE) is an establishment where medical services are rendered. These services are provided by the health care personnel. The infrastructure of a HCE may include Information Technology (IT) equipment that stores and processes HC information. The spread of distributed information technology in HCEs have necessitated the implementation of Network Security in Health Care Information System (HCISs), to assure confidentiality, integrity and availability of HC information being transmitted across HC networks. This paper presents a road map in implementing Network Security guidelines for the provision of Network Security in HCEs, work carried out within the Secure Environment for Information Systems in Medicine (SEISMED) project under the Advanced Informatics in Medicine (AIM) programme.

Designing a knowledge management system for distributed activities: a human centered approach.

In this study we use the principles of distributed cognition and the methodology of human-centered distributed information design to analyze a complex distributed human-computer system, identify its problems, and generate design requirements and implementation specifications of a replacement prototype for effective organizational memory and knowledge management. We argue that a distributed human-computer information system has unique properties, structures and processes that are best described in the language of distributed cognition. Distributed cognition provides researchers a richer theoretical understanding of human-computer interactions and enables re-searchers to capture the phenomenon that emerges in social interactions as well as the interactions between people and structures in their environment.
