In mathematics, especially in linear algebra and matrix theory, the duplication matrix and the elimination matrix are linear transformations used for transforming half-vectorizations of matrices into vectorizations or (respectively) vice versa.
The Andersen healthcare utilization model is a conceptual model aimed at demonstrating the factors that lead to the use of health services. According to the model, the usage of health services (including inpatient care, physician visits, dental care etc.) is determined by three dynamics: predisposing factors, enabling factors, and need.
The system is named after Nikolai Semashko, a Soviet People's Commissar for Healthcare. [1] The model is largely continued in Russia , most other post-Soviet states [ 2 ] (exceptions are: Turkmenistan, Kyrgyzstan and the Baltic states), and some other formerly Soviet-aligned states (such as North Korea [ 3 ] and Cuba [ 4 ] ) and is regarded as ...
The Donabedian model is a conceptual model that provides a framework for examining health services and evaluating quality of health care. [1] According to the model, information about quality of care can be drawn from three categories: "structure", "process", and "outcomes". [ 2 ]
Health care efficiency is a comparison of delivery system outputs, such as physician visits, relative value units, or health outcomes, with inputs like cost, time, or material. Efficiency can be reported then as a ratio of outputs to inputs or a comparison to optimal productivity using stochastic frontier analysis or data envelopment analysis .
Easterling and colleagues (REF LHS 2022) proffer an elaborate taxonomy of LHS elements and use this to describe an LHS-IP, or “Learning Health System In Practice” as a model for health care systems who seek to become an LHS. [26] The motivations for applying LHS concepts are largely and logically focused on improving the quality of care.
In the United States, disease management is a large industry with many vendors. Major disease management organizations based on revenues and other criteria [5] [6] include Accordant (a subsidiary of Caremark), Alere (now including ParadigmHealth and Matria Healthcare), [7] Caremark (excluding its Accordant subsidiary), Evercare, Health Dialog, Healthways, LifeMasters (now part of StayWell ...
The model incorporates the complex adaptive healthcare system as a key characteristic. Complex adaptive systems characteristically demonstrate self-organization as diverse agents interact spontaneously in nonlinear relationships [ 4 ] [ 5 ] where professionals act as information processors (Cilliers, 1998; McDaniel & Driebe, 2001) and co-evolve ...
