Acceptance testing of integrated picture archiving and communications systems.
(33/1092)
An integrated picture archiving and communication system (PACS) is a large investment in both money and resources. With all of the components and systems contained in the PACS, a methodical set of protocols and procedures must be developed to test all aspects of the PACS within the short time allocated for contract compliance. For the Department of Defense (DoD), acceptance testing (AT) sets the protocols and procedures. Broken down into modules and test procedures that group like components and systems, the AT protocol maximizes the efficiency and thoroughness of testing all aspects of an integrated PACS. A standardized and methodical protocol reduces the probability of functionality or performance limitations being overlooked. The AT protocol allows complete PACS testing within the 30 days allocated by the digital imaging network (DIN)-PACS contract. AT shortcomings identified during the testing phase properly allows for resolution before complete acceptance of the system. This presentation will describe the evolution of the process, the components of the DoD AT protocol, the benefits of the AT process, and its significance to the successful implementation of a PACS. This is a US government work. There are no restrictions on its use. (+info)
Meta-manager: a requirements analysis.
(34/1092)
The digital imaging network-picture-archiving and communications system (DIN-PACS) will be implemented in ten sites within the Great Plains Regional Medical Command (GPRMC). This network of PACS and teleradiology technology over a shared T1 network has opened the door for round the clock radiology coverage of all sites. However, the concept of a virtual radiology environment poses new issues for military medicine. A new workflow management system must be developed. This workflow management system will allow us to efficiently resolve these issues including quality of care, availability, severe capitation, and quality of the workforce. The design process of this management system must employ existing technology, operate over various telecommunication networks and protocols, be independent of platform operating systems, be flexible and scaleable, and involve the end user at the outset in the design process for which it is developed. Using the unified modeling language (UML), the specifications for this new business management system were created in concert between the University of Arizona and the GPRMC. These specifications detail a management system operating through a common object request brokered architecture (CORBA) environment. In this presentation, we characterize the Meta-Manager management system including aspects of intelligence, interfacility routing, fail-safe operations, and expected improvements in patient care and efficiency.

Process mapping in screening mammography.
(35/1092)
Successful screening mammography programs aim to screen large numbers of women efficiently and inexpensively. Development of an effective screening mammography program requires skilled personnel, solid infrastructure, and a robust computer system. A group of physicians, technologists, computer support personnel, and administrators carefully analyzed a growing screening mammography program as a series of steps, starting with the request for the examination and ending with the receipt of a hard-copy consultation. The analysis involved a detailed examination of every step and every possible outcome in the screening process. The information gained through process mapping may be used for identification of systemic and personnel problems, allocation of resources, modification of workplace architecture, and design of computer networks. Process mapping is helpful for those involved in designing and improving screening mammography programs. Viewing a process (i.e., obtaining a screening mammogram) as a series of steps may allow for the identification of inefficient components that may limit growth. (+info)
Evaluating a picture archiving and communications system workstation.
(36/1092)
An efficient environment for picture archiving and communications systems (PACS) in the radiology department and throughout a medical practice requires good hardware, good software, and integration of the information sources that exist in a radiology department and institution. This tutorial will describe some of the considerations in evaluating a PACS workstation, with a view to the hardware requirements, user interface designs, and integration with the information systems.

Rethinking human resources: an agenda for the millennium.
(37/1092)
Health care reforms require fundamental changes to the ways in which the health workforce is planned, managed and developed within national health systems. While issues involved in such transition remain complex, their importance and the need to address them in a proactive manner are vital for reforms to achieve their key policy objectives. For a start, the analysis of human resources in the context of health sector appraisal studies will need to improve in depth, scope and quality by incorporating functional, institutional and policy dimensions.

The costs of hospital services: a case study of Evangelical Lutheran Church hospitals in Tanzania.
(38/1092)
The health care systems of many developing countries are facing a severe crisis. Problems of financing services leads to high patient fees which make institutions of Western health care unaffordable for the majority of the rural poor. The conflict between sustainability and affordability of the official health care system challenges both local decision-makers and health management consultants. Decisions must be made soon so that the existing health care systems can survive. However, these decisions must be based on sound data, especially on the costs of health care services. The existing accounting systems of most hospitals in developing countries do not provide decision-makers with these data. Costs are generally underestimated. The leadership of the 16 hospitals of the Evangelical Lutheran Church in Tanzania is currently analyzing how the existing health care services should be restructured. Therefore, reliable estimates of the costs of hospitals services are required. A survey on 'Costing of health services of the Evang. Luth. Church in Tanzania' was prepared, which summarizes the results of seven months of field investigations in Lutheran hospitals. The major findings are that the costs of providing adequate services are much higher than expected. The most important factors determining these costs are the administrative efficiency of the hospital and the scope of services offered. The paper closes with some recommendations on how to improve the services in order to make them both affordable for the rural poor and financially sustainable for the Church. It is concluded that even the best improvement of technical efficiency will not safeguard the survival of the hospital-based health care services of the Lutheran Church in Tanzania. These findings call for a reallocation of health care resources to lower levels of the health care pyramid. (+info)
Reforming health service delivery at district level in Ghana: the perspective of a district medical officer.
(39/1092)
Many countries in sub-Saharan Africa face the problem of organizing health service delivery in a manner that provides adequate quality and coverage of health care to their populations against a background of economic recession and limited resources. In response to these challenges, different governments, including that of Ghana, have been considering or are in the process of implementing varying degrees of reform in the health sector. This paper examines aspects of health services delivery, and trends in utilization and coverage, using routine data over time in the Dangme West district of the Greater Accra region of Ghana, from the perspective of a district health manager. Specific interventions through which health services delivery and utilization at district level could be improved are suggested. Suggestions include raising awareness among care providers and health managers that increased resource availability is only a success in so far as it leads to improvements in coverage, utilization and quality; and developing indicators of performance which assess and reward use of resources at the local level to improve coverage, utilization and quality. Also needed are more flexibility in Central Government regulations for resource allocation and use; integration of service delivery at district level with more decentralized planning to make services better responsive to local needs; changes in basic and inservice training strategies; and exploration of how the public and private sectors can effectively collaborate to achieve maximum coverage and quality of care within available resources.

Trauma center maturation: quantification of process and outcome.
(40/1092)
BACKGROUND AND OBJECTIVE: The regional trauma system with the trauma center as its center is a model for health care networks. However, trauma center maturation has not been defined in the literature. The authors' hypothesis was that maturation of the trauma center would affect quantitatively both process and patient outcome. MATERIALS AND METHODS: A total of 15,303 trauma patients were admitted from 1987 to 1995. Annual admissions increased from 813 to 2669. Resources were generated as patient volume increased. Time to the operating room, length of stay, and complications were determined. TRISS methodology was used to calculate z scores and w values to compare actual with predicted mortality rates. RESULTS: Time to the operating room for laparotomy decreased from 62+/-73 to 35+/-47 minutes, from 32+/-32 to 20+/-17 minutes in hypotensive patients, and for craniotomy decreased from 88+/-54 to 67+/-49 minutes. The incidence of infectious, airway, neurologic, orthopedic, respiratory, gastrointestinal, and procedure-related complications declined significantly. Z scores and w values increased for penetrating and blunt injuries. Deaths for patients with ISS >15 declined significantly. Hospital length of stay decreased for all ranges of injury severity. CONCLUSIONS: As the trauma center matured, the process of delivering patient care became more efficient. The result was improved survival, fewer complications, and a shorter length of stay. (+info)
