Processes that are inefficient and variable, changing case mix of patients, health insurance, differences in provider education and experience, and numerous other factors contribute to the complexity of health care. The goals of measuring health care quality are to determine the effects of health care on desired outcomes and to assess the degree to which health care adheres to processes based on scientific evidence or agreed to by professional consensus and is consistent with patient preferences.
History[ edit ] Initial efforts to control the quality of production[ edit ] During the Middle Agesguilds adopted responsibility for the quality of goods and services offered by their members, setting and maintaining certain standards for guild membership.
For this reason, King John of England appointed William de Wrotham to report about the construction and repair of ships. The Industrial Revolution led to a system in which large groups of people performing a specialized type of work were grouped together under the supervision of a foreman who was appointed to control the quality of work manufactured.
Wartime production[ edit ] During the time of the First World Warmanufacturing processes typically became more complex, with larger numbers of workers being supervised. This period saw the widespread introduction of mass production and piece workwhich created problems as workmen could now earn more money by the production of extra productswhich in turn occasionally led to poor quality workmanship being passed on to the assembly lines.
Pioneers such as Frederick Winslow Taylor and Henry Ford recognized the limitations of the methods being used in mass production at the time and the subsequent Quality assurance and quality improvement processes quality of output.
Taylor, utilizing the concept of scientific management, helped separate production tasks into many simple steps the assembly line and limited quality control to a few specific individuals, limiting complexity.
Shewhart at Bell Laboratories in the early s. Shewhart developed the control chart in and the concept of a state of statistical control. Statistical control is equivalent to the concept of exchangeability   developed by logician William Ernest Johnson also in in his book Logic, Part III: The Logical Foundations of Science.
Shewhart consulted with Colonel Leslie E. Simon in the application of control charts to munitions manufacture at the Army's Picatinny Arsenal in General Douglas MacArthur oversaw the re-building of Japan.
During this time, General MacArthur involved two key individuals in the development of modern quality concepts: Edwards Deming and Joseph Juran. Both individuals, as well as others, promoted the collaborative concepts of quality to Japanese business and technical groups, and these groups utilized these concepts in the redevelopment of the Japanese economy.
In mechanical terms this is the operation of a product until it fails, often under stresses such as increasing vibrationtemperatureand humidity.
This exposes many unanticipated weaknesses in a product, and the data is used to drive engineering and manufacturing process improvements. Often quite simple changes can dramatically improve product service, such as changing to mold -resistant paint or adding lock-washer placement to the training for new assembly personnel.
Statistical control[ edit ] Statistical control is based on analyses of objective and subjective data. Any product can be statistically charted as long as they have a common cause variance or special cause variance to track.
Control can then be implemented on the part in the form of rework or scrap, or control can be implemented on the process that made the part, ideally eliminating the defect before more parts can be made like it.
Total Quality Management The quality of products is dependent upon that of the participating constituents,  some of which are sustainable and effectively controlled while others are not.
If the specification does not reflect the true quality requirements, the product's quality cannot be guaranteed. For instance, the parameters for a pressure vessel should cover not only the material and dimensions but operating, environmental, safetyreliability and maintainability requirements.
Models and standards[ edit ] ISO is an international standard that specifies the general requirements for the competence to carry out tests and or calibrations.
There are 15 management requirements and 10 technical requirements. These requirements outline what a laboratory must do to become accredited. Management system refers to the organization's structure for managing its processes or activities that transform inputs of resources into a product or service which meets the organization's objectives, such as satisfying the customer's quality requirements, complying with regulations, or meeting environmental objectives.
WHO has developed several tools and offers training courses for quality assurance in public health laboratories. The CMMI maturity levels can be divided into 5 steps, which a company can achieve by performing specific activities within the organization. Company quality[ edit ] During the s, the concept of "company quality" with the focus on management and people came to the fore in the U.
The company-wide quality approach places an emphasis on four aspects enshrined in standards such as ISO QA is not limited to manufacturing, and can be applied to any business or non-business activity, including: It comprises a quality improvement process, which is generic in the sense that it can be applied to any of these activities and it establishes a behavior patternwhich supports the achievement of quality.
This in turn is supported by quality management practices which can include a number of business systems and which are usually specific to the activities of the business unit concerned.Quality Improvement Strategies.
More than 40 years ago, Donabedian 27 proposed measuring the quality of health care by observing its structure, processes, and outcomes. Structure measures assess the accessibility, availability, and quality of resources, such as health insurance, bed capacity of a hospital, and number of nurses with advanced training.
Quality assurance processes and procedures ensure that your customers receive a consistent product or service every time. Standard – Quality Assurance and Improvement Program states, “The chief audit exec-utive must develop and maintain a quality assurance and improvement program that covers of IA Processes Quality Assurance Over Entire IA Activity Continuous Improvement of QAIP Reporting & Follow-Up.
Basics of Quality Improvement such as National Committee for Quality Assurance’s (NCQA Quality improvement tools are standalone strategies or processes that can help you better.

A culture of improvement frequently develops in an organization that is committed to quality, because errors are reported and addressed. "Improved communication with resources that are internal and external to an organization, such as, funders, civic and community organizations.
