An application of linear programming discriminant analysis to classifying and predicting the symptomatic status of HIV/AIDS patients.

This study presents an application of linear programming discriminant analysis (LPDA) to classify and to predict the symptomatic status of HIV/AIDS patients. We applied LPDA as well as several traditional discriminant analysis methods to the AIDS Cost and Services Utilization Survey data set in order to demonstrate the use of LPDA to classify the symptomatic status of HIV/AIDS patients. The potential benefit of LPDA in terms of the classification accuracy was also analyzed.

A human resource planning model for hospital/medical technologists: an analytic hierarchy process approach.

This paper deals with the development of a human resource planning (HRP) model for hospital laboratory personnel. External and organizational factors impacting the demand and supply of clinical laboratory personnel in an urban academic health center are identified by a Delphi process. These factors are structured into a hierarchy for the application of the Analytic Hierarchy Process (AHP). Computer software, Expert Choice, was used in model hierarchy development and judgmental elicitation process. The model result can be applicable to eliciting the perceptions, insights, and understanding of health-care decision-makers for strategic human resource planning.

A linear goal programming model for human resource allocation in a health-care organization.

This paper presents the development of a goal programming (GP) model as an aid to strategic planning and allocation for limited human resources in a health-care organization. The purpose of this study is to assign the personnel to the proper shift hours that enable management to meet the objective of minimizing the total payroll costs while patients are satisfied. A GP model is illustrated using the data provided by a health-care organization in the midwest area. The goals are identified and prioritized. The model result is examined and a sensitivity analysis is performed to improve the model applicability. The GP model application adds insight to the planning functions of resource allocation in the health-care organizations. The proposed model is easily applicable to other human resource planning process.

A neural network application to classification of health status of HIV/AIDS patients.

This paper presents an application of neural networks to classify and to predict the health status of HIV/AIDS patients. A neural network model in classifying both the well and not-well health status of HIV/AIDS patients is developed and evaluated in terms of validity and reliability of the test. Several different neural network topologies are applied to AIDS Cost and Utilization Survey (ACSUS) datasets in order to demonstrate the neural network's capability.

An inventory model for optimizing purchasing of intravenous fluids for hospitals: a case study.

This paper deals with determining the optimal level of purchase of intravenous fluids for hospitals by utilizing inventory control concepts. Using the conceptual framework of the economic order quantity (EOQ) model, the hospital administrators can elicit the efficient materials management, thus reducing both the space and capital requirements without compromising the quality of services rendered.

The value of battery testing in the clinical laboratory: a PERT network case study.

This paper presents procedures for battery testing for the diagnosis and monitoring of treatment of patients' bleeding disorders. Specifically, it describes the testing performance for a group of bleeding disorders, disseminated intravascular coagulation (DIC). The value of three battery-testing procedures is examined by using a PERT technique, based on the clinical data obtained from the Saint Louis University Hospitals. The study reveals that a grouping of test procedures provides better patient care and improved utilization of clinical laboratory, while reducing the operational costs.

An analysis of standardized disease classification system for health care planning.

This paper deals with the development of the standardized disease classification system, which generates usable statistics for comprehensive health care planning. It is used by ARCH (a regional health planning agency) to obtain a measure of acute hospital utilization and regional health status. A sample of 35,000 patients discharged from 39 acute-care facilities in the St. Louis bistate region was examined and tested. The existing disease classification systems (three versions of ICD and SNDO) were converted into the standardized system. Its application results in a better conceptualization of current health problems. It aids in the formulation and monitoring of health problems.
