    2 Quality 4.0 for improving quality of healthcare

    Healthcare professionals wish to improve the quality of healthcare with reduced effort, keeping in view the increasing public demand for safety, quality, and transparency. Additionally, doctors are attempting to improve their sequela in the interest of public health and patients. The Quality 4.0 revolution highlights the necessity of quality improvements in the field of healthcare. For performance improvements, at the end of every quality assessment period, staff and providers should have sufficient information to perform modifications that lead to the development of a new policy[16,17].

    Modern healthcare requires an upgraded quantitative assessment system rather than a traditional quality control or assessment system. A system that deals with the activities professionally should maintain efficiency at every stage of processing. Efficiency in the medical field must be maintained for the outputs, as this sector directly deals with human lives.Thus, the results of a medical procedure are the measure of success. The effectiveness of medical procedures is difficult to measure owing to the limited outcome knowledge, lack of evidence-based guidelines, and data accessibility problems. Healthcare often adopts quantitative measures, but this usually focuses on profit and loss reports. Highly detailed information can be obtained as profit/loss reports are more vital to operations, revenue, and cost/procedure etc.[18,19].

    Healthcare professionals are dedicated to satisfying the quality measures or standards that are aligned with professional ethics, law, and regulations.Controlled protocols and quality assurances are the means of gauging the standards of care to find nicety in professional practice. A plan that can provide quality assurance must include the following elements:

    · Identification of quality issues

    · Development of a problem-resolution strategy

    · Progression of quality assessment

    · Implementation of changes.

    2.1 Features of Quality 4.0 for supporting healthcare

    The Quality 4.0 philosophy is a unique and promising idea that can be employed to serve the healthcare domain, particularly during the COVID-19 pandemic. The vital components of Quality 4.0 and its services allow healthcare to be improved with regard to the level of care and patient satisfaction.Figure 1 presents the numerous vital components and elements that comprise this quality-based philosophy for healthcare[20,21].

    It includes many classes of factors, revealed facts,notions, and concepts derived from the background of quality and its revolutions towards the healthcare domain’s sustenance at several platforms. It further explores the applicability of analytics, connectivity,scalability, and quality culture throughout the healthcare platforms. This usage of Big Data, better and efficient supply chains, wellness hubs, cloud-based facts, etc., makes the fourth quality revolution successful in serving healthcare effectively and competently[22,23].

Quality 4.0 provides an advanced approach for implementing the optimal strategy for treatment and services. The quality revolution provides a better opportunity for quality movement and adopts quality assurance for better future advancement. This creates significant technological advancements in the field of healthcare and can interact with doctors with the patient. In Quality 4.0, all processes are involved digitally and software-controlled[26,27], reducing errors and simplifying the traditional treatment process.

    2.3 Quality 4.0 for fulfilling patient-specific needs

    Currently, the entire healthcare sector is transforming according to patient-centric needs, as it lacks quality and consistency in the changing healthcare industry. For achieving complete patient satisfaction, healthcare professionals are directly involved in patient-centric outcomes. The medical field is in the early stage of incorporating new technologies to cope with these changes with the help of Quality 4.0. Previous efforts to satisfy the standards involved patient feedback and public surveys[28,29].

    Achievements can be monitored as per the required goals. Doctors attempt to provide patientcentric treatments according to individuals’ needs to maintain international hygiene and standards. There is no confusion among doctors to develop a quality system based on patients’ requirements. This can be accomplished only by enhancing patients’ satisfaction for improving the overall reputation of the healthcare practice. Two main factors that can play an essential role in the enhancement of healthcare are improvements in the organization and management of practice[30,31]. For a particular organizational system, quality in practice should satisfy requirements. Such requirements will help the organization in many ways, e.g.,

    · Reduce financial losses

    · Minimize mistakes in routine practices

    · Increase precision in operational procedures

    · Improve skill sets, boosting efficiency levels

    · Maximize the use of resources

    · Enhance performance as per standards.

    3 Crucial roles of Quality 4.0 philosophy in healthcare support during COVID-19

    Philosophies like Quality 4.0 are reported as a perfect candidate that serves all the features and strategies in improving the healthcare domain. During the pandemic, patients with severe health issues fear catching the coronavirus and are now courageous enough to visit nearby care centers. Such issues are also revealed to be fruitful when implementing the quality aspects in well-established TCM approaches for satisfying societal/national healthcare-related needs. To resolve the aforementioned issues, Quality 4.0 and its smart services offer fruitful outcomes with regard to smart care, better treatments for patients,remote service, learning with working, applications of smart processing, compatible materials, etc. for enhancing patient satisfaction[32,33].

    Figure 2 Roles and responsibilities in Quality 4.0 for healthcare during COVID-19

    Figure 2 shows the various roles, features, and strategies being offered to apply quality-based services in the broad domain of healthcare. The roles and services, which include information security management, information technology facts, software services, and cloud-based data reflections, enable the Quality 4.0 philosophy strategies for the extensive care and support for patients, particularly during the current coronavirus and in cases of similar pandemics.The benefits of the quality system are not limited to the healthcare field but applicable to various industries. Enhancing quality refers to improvements in overall measures or standards at all levels of the healthcare sector so that a patient can feel safer and more satisfied. The proposed digitalized TCM-based healthcare support services will help physicians to provide patients the highest-quality service with consideration of hygiene, safety, and modern treatment and the healthcare practitioner’s professional skills. Thus, Quality 4.0 technologies provide better procedures and quality improvement throughout the entire TCM structure[34-37]. This can eliminate pain during the treatment of the patient. A healthy condition can be maintained with the proper daily perpetuation and timely visits to the doctor. The doctors can quickly address problems using the latest technology, which can be implemented for patients of all ages.

    4 Significant applications Quality 4.0 in healthcare during COVID-19 pandemic

    The major role of digital technologies is to enable person-centered care with reduced human interaction. These technologies also overcome the challenges of data storing and sharing, thereby supporting the decision-making process. The demand for digital healthcare services with the support of the TCM framework/treatment is increasing owing to the COVID-19 pandemic. With the introduction of these technologies, the wastage of time during the treatment process is reduced. This can be flexibly automating the medical devices and efficiently resolving the challenges.
