Applications of Framework in Health Care: A Survey, and
The use of healthcare frameworks and, in particular, policy makers is crucial for designing and evaluating systems. Frameworks provide the ability to measure and compare health system functions in different countries in order to make better and more meaningful decisions, to make comparisons within and between countries, identifying gaps, and sharing information. Researchers also have the ability to use the dimensions of the frameworks to measure progress over time. Due to the importance of the subject, the purpose of this study is to describe the framework concepts and the introduction of framework applications in the field of health care.
Material and Methods:
This study is based on a search of the ProQuest, PubMed, Google Scholar, Science Direct, Scopus, IranMedex, Irandoc, Magiran, ParsMedline and Scientific Information Database (SID) databases, as well as the study of specialized keyword web sites and the standard was done. After a thorough study, 50 sources were selected according to the study objectives and were used to formulate the final article.
The framework can be used to manage health system investments, identify important research areas in the field of health, and define new and useful research.
The framework focuses on one thing why and how it should work; in fact, it provides the user with a map; it is a prefabricated template or pattern that manages most common and duplicate features and the possibility provides reuse [1, 2]. In other words, a framework is a basic conceptual framework that is used to solve complex problems and is usually a set of tools, materials, or components . This is a phrase from the architecture world to software and sometimes managed . It has applications for improving and redesigning processes and services, designing and manufacturing systems, designing/ revising an enterprise architecture, integrating systems and e-services, designing new services/ products, and incorporating many benefits, including simplicity, high performance, integration ability, higher security, the ability to develop, facilitate program updates, the ability to reuse written codes [5, 6].
Frameworks have different types, including theoretical frameworks, conceptual frameworks, operational frameworks, and software frameworks. Theoretical frameworks deal with the relationships between variables such as independent, dependent, interferential and transformative variables, helping to create such frameworks in establishing and constructing hypotheses, measuring them as well as completing a researcher's perception (research question) . The theoretical framework statement is usually used in quantitative research. While the researcher uses a theory or a combination of several theories to prepare a road map and explain research hypotheses. In a study, a theoretical framework for coordination care in chronic diseases requiring long-term care was presented. This framework included the association of the team members with the patient for proper interaction, team features including cultural characteristics, workload, work complexity, etc. . In a study, the presentation of a theoretical framework for Public Health Ethics includes the production of benefits, avoiding, preventing, removing harms, and utility, distributive justice, respecting autonomous choices and actions, protecting privacy and confidentiality, keeping promises and commitments, disclosing information, speaking truthfully, building and maintaining trust .
A conceptual framework is a set of general goals and related basics that determine overall goals and objectives, and defines the basics and concepts for achieving these goals. These concepts are tips for choosing events, deals, and conditions to be considered [8-10]. Conceptual framework terms are commonly used in qualitative research. The researcher uses the analysis and categorization of previous research findings as a road map for designing research tools and research questions. In studies of conceptual frameworks, for the analysis of health care organizations' performance, for performance of healthcare, including effectiveness, quality and improvement, for measuring the performance of the public health system, for quality of care, including the dimensions of efficacy, effectiveness, efficiency, empathy, and environment, for developing a comprehensive e-health assessment tool, for the IOT-based health care system using cloud computing, and the theoretical frameworks in this regard to determine good health status in Jamaica, And for supporting research on health service innovation [11-20].
The operational framework includes guiding principles, specific criteria, steps, methods and attributes that relevant to corporate policies, goals, standards, procedures and training. Generally, it describes the corporate organization or management structure. It includes how the leaders manage the company and its hierarchy of divisions or management teams. It includes policy makers of the company. It can include a guide to the principles of behavior, recruitment and promotion . In a study, an operational framework for health policy included process, actor, content and context items . A community-based care for mothers and infants in Queensland was also presented in the form of an operational framework, in the form of essential roles and dimensions . The proposed operational framework for risk management involves injury training, athlete monitoring, risk factors, sports requirements, athlete profiles, athlete management, which can be helpful for practitioners in managing risk of injury .
The software framework is a framework for helping startup programs, and by putting all of the software components together, it is possible to develop a project or system. They can include support programs, compilers, libraries, tools and APIs . A study was designed to use practical statistical frameworks for recommending medication to diabetic patients . A study was performed using panel ensemble techniques to determine benign or malignant breast cancer . A study was developed using probabilistic frameworks that processed mammography images for cancer diagnosis .A framework study presented using the Bayesian method for determining variations in EEG / FMRI .

7. Web based ontology language framework
The importance of semantic interaction between clinical information has been proposed by Legaz-Garca et al. To determine the semantic integration of Health Care Electronic Data (EHR), a Web Ontology Language (OWL) framework called ArchMS has been proposed. The data collected from relational databases to construct the ontology are converted to OWL and then the anthology built to explore data such as EHR-based classification and visualization, as presented in Fig 7.

10. Integrated big data framework:
Jokonya et al.  proposed an integrated large data framework to help control and prevent diseases such as HIV/AIDS (Human Immunodeficiency Viruses/Acquired Immune Deficiency Syndrome), Tuberculosis, and Silicosis (abbreviated as HATS). This framework addresses the need for a statistical prevention model to predict and control these diseases. Fig 9 shows the suggested framework.
11. RFID-based healthcare framework
The interest in RFID (Radio-Frequency Identification) technology in the healthcare industry has increased. This technology is used for such things as tracking medical equipment, hospital supplies, patient information and medications. While this technology has important implications, it raises privacy concerns. Rahman et al.  proposed an RFID-based healthcare framework, PriSens-HSAC, to address privacy issues. As shown in Fig 10, this framework contains two components:
Used as an authentication protocol to measure RFID tags.
Provides a mechanism for accessing the health care service to ensure user privacy.

14. Personalized big data framework for real-time health care preparation
A big-data framework for real-time personalized health care customization based on field-based surveillance technology has been presented by Forkan et al. (Fig 13). This framework facilitates big data analysis within a cloud environment to detect patient-specific anomalies from large amounts of data. With the advent of the cloud, the big data generated is collected from heterogeneous fields and implements a two-step methodology .
The first step is to apply a Map-Reduce based Apriori algorithm to discover the relationship between field characteristics and threshold values of critical parameters of patient data.
Second, supervised learning algorithms, such as multilayer perceptron networks, decision trees, Bayesian networks, are implemented on the associative rules produced to implement context-aware decision making.
15. A framework for evaluating health information technology
Improving quality, efficiency and effectiveness of health services are the most important goals of health systems. If health organizations have the appropriate structure in place to regularly evaluate health information systems, they play an effective role in achieving these goals. The purpose of designing and implementing health information systems evaluation is to ensure the availability, use and applicability of data necessary to measure key health indicators.
Sadoughi et al.  described the process of evaluating health information systems, focusing on the WHO program. The stages of evaluating health information systems from the World Health Organization's perspective are as follows:
1) Determine the scope of authority
2) Collect and review existing relevant information
3) Finalize the evaluation services and topics
4) Determine system performance indicators
5) Designing and testing evaluation tools
6) Evaluation logistics
7) Performing evaluation
8) Analyze the results and prepare the evaluation report
9) Adjustment suggestions and preparation of the operation plan 
A conceptual framework for evaluating health information technology has been proposed by Eisenstein et al., Which can be used for hospitals, clinics, and health care systems .
1) Domain: Specifies the difference between an information intervention and its achievement.
2) Mechanism: Specifies the specific components of the new information technology or health care system so that it can be the subject of an evaluation study. 3) Timing: Determines the occurrence before or after the implementation of health information technology.
The answers to these three questions determine a set of evaluation types, each comprising a set of evaluation questions, study designs, data collection requirements, and analysis methods.
16. Framework for comprehensive health service evaluation and monitoring
Reeve et al.  developed a framework for evaluating and monitoring a health care service, integrating hospital and community services. This framework comprises three main areas: structure, process, and outcome to determine health service performance (Fig 14).
17. Development of frameworks for the semantic interaction of health information systems
The major challenge for health information systems is the semantic interaction for establishing shared e-health care. Lopez et al.  proposed a framework for the semantic interaction of health information systems. The proposed methodology is based on the Rational Unified Process (RUP) to integrate with other architectural approaches such as Service-Oriented Architecture (SOA), Model-Driven Architecture (MDA), ISO 10746, and HL7 Development Framework (HDF). The following Fig 15 shows the framework architecture.
18. A framework for monitoring the health system
In the global model of the health system, the role of governance and leadership is very important. Coordination between the various public and private actors in the utilization of health resources (labor, information, equipment and technology as well as the necessary funding) provides essential services to promote health and meet the needs of the community and fair participation in the provision of resources. Improving governance and leadership performance in the health system has an indispensable role in promoting health system functions such as fairness, efficiency and effectiveness and continuity in service delivery.
The model proposed by Mehrolhassani et al.  consists of 5 components:
Governance and Leadership:
A key component of the model, it regulates strategies and policies of other dimensions and areas of the health system.
Provision of services:
Includes different levels such as: primary health care, family physician, home care, health and hospital services, and rehabilitation
The situation is monitored for basic demographic indicators as well as mortality, disease burden and risk factors.
Examines the status of financing locations, resource accumulation, purchasing and resource specialization, payment system and strategic purchasing of services.
Examines the components of human resource management, knowledge and information, equipment and medicine as well as the legal nature of organizations.
Although these frameworks pursue specific health care goals, they are geared towards adopting standard architectural guidelines such as data collection, pre-processing, data analysis, interpretation and visualization. Due to the specific nature of the scope of the big data healthcare framework, professionals should make the utmost effort to select the tools used at different levels of the design and implementation of the framework [47, 48].
Various frameworks have been presented to date in the field of health care; for example, the framework for controlling and planning health care was proposed by Hall , which the hospital managers used using the components of the framework, including resource management and principles Strategic counseling can be taken to improve care services. An applied conceptual framework of the health care system is also presented using big data analysis by Raghupathi and Raghupathi . This framework works for researchers who intend to use big data analyzes in the field of health as a road map. Rahman et al.  provided a RFID-based healthcare framework for addressing security issues. In this framework, two RFID tag-based authentication components and privacy have been considered as two important factors in maintaining security. Lopez et al.  introduced a framework for communicating between health information systems using the standards, protocols, and principles of interaction in these types of systems. Mehrolhassani et al. presented a framework for monitoring the health system, which can be used to evaluate a good health system, taking into account dimensions such as the financial dimension and delivery of services. Reeve et al.  developed a comprehensive evaluation and monitoring framework for a comprehensive health system that covers three areas of structure, process, and achievement. Chawla and Davis  suggested a personalized framework for the patient that the patient, using a mechanism based on the profiles of similar patients, predicted the risk for each patient. Considering the importance of focusing on the Big Data Area  and providing a lot of frameworks in this area, it is recommended that other important health care sectors provide frameworks in this regard, and it is also recommended in future studies of other widely used tools for software engineering in the field of health care Including modeling, simulations, etc., are being investigated, introduced and used .
The framework is a valuable and widely used concept in the field of health care, which has been used in recent years. In this paper, the survey reviewed its implications in the field of health care. The framework in the field of health care has many advantages and especially for policy-makers to evaluate the system, measure and compare the function of health systems in different countries, for key decisions, the possibility of comparison within and between countries, identification Chatting and sharing of information. The results obtained on the basis of the framework can be used to manage health system investments, identify important fields of research in the field of health, as well as areas that are important and less worthwhile, and define new and useful research. The possibility of designing standard systems is provided.
