DESIGN AND COMPUTERIZED OF MEDICAL LABORATORY SYSTEM INFORMATION CASE STUDY OF MACHU’S LABORATORY

ABSTRACT

A laboratory (informally, lab) is a facility that provides controlled conditions in which scientific research, experiments, and measurement may be performed. The title of laboratory is also used for certain other facilities where the processes or equipment used are similar to those in scientific laboratories. Labs used for scientific research take many forms because of the differing requirements of specialists in the various fields of science. A chemist or biologist might use a wet laboratory, while a psychologist’s lab might be a room with one-way mirrors and hidden cameras in which to observe behavior. Scientists in other fields will use still other types of laboratories. Despite the great differences among laboratories, some features are common. The use of workbenches or countertops at which the scientist may choose to either sit or stand is a common way to ensure comfortable working conditions for the researcher, who may spend a large portion of his or her working day in the laboratory. The provision of cabinets for the storage of laboratory equipment is quite common. It is traditional for a scientist to record an experiment’s progress in a laboratory notebook, but modern labs almost always contain at least one computer workstation for data collection and analysis.

ORGANIZATION OF WORK

          This project work is primarily designed to give an insight into Computerized medical laboratory system information used in hospitals.

          Chapter one talks about introduction to Computerized medical laboratory system information, study of problem and objectives as well as definition of the scope.

          Chapter two comprises the literature review. Chapter three gives the detailed information about the existing (old) system, while chapter four and five deals with the design and implantation of new system.

          Chapter six documents the project work, while chapter seven summaries, conclusion and suggestions were made.

INTRODUCTION

A lab information system (“LIS”) is a class of software that receives, processes, and stores information generated by medical laboratory processes. These systems often must interface with instruments and other information systems such as hospital information systems (HIS). A LIS is a highly configurable application which is customized to facilitate a wide variety of laboratory workflow models. Deciding on an LIS vendor is a major undertaking for all labs. Vendor selection, typically takes months of research and planning. Installation takes from a few months to a few years depending on the complexity of the organization. There are as many variations of LISs as there are types of lab work. Some vendors offer a full service solution capable of handling a large hospital lab’s needs, others specialize in specific modules. Disciplines of laboratory science supported by LIS’ include hematology, chemistry, immunology, blood bank (Donor and Transfusion Management), surgical pathology, anatomical pathology, flow cytometry and microbiology. This article covers clinical lab which encompasses hematology, chemistry and immunology. Laboratory Information Systems are often part of an integrated informatics solution which involve many disparate applications. Use of an LIS is a critical piece of the clinical IT spectrum of systems and contributes significantly to the overall care given to patients. The LIS is used in inpatient and outpatient settings and in many cases is designed to support both. From an outpatient/ambulatory perspective, LIS interaction frequently begins after a physician has arrived at an initial diagnosis. For example, a patient enters the hospital looking pale and complaining of fatigue. The physician, suspecting anemia, might decide to order a Full blood count (FBC). In an inpatient setting when that patient is admitted into the hospital, the system is used to order tests, provide specimen processing assistance, receive the results from analyzers and deliver lab reports to the attending physician

1. STATEMENT OF PROBLEM

Owing to:

• The difficulties in detecting some sicknesses.
• Complex system of human being.
• Inability of Doctors to know the actual cause of alignment.
• Risk involve in prescribing drugs based on assumption.

The need arise for the development of Computerized medical laboratory system information that will enable doctors solve these problems.
