Introduction
The rapid spread of information technology (IT) has revolutionized every facet of life over the past few decades (Ahmed et al., 2021). During the Coronavirus pandemic (COVID-19 pandemic), the role of IT has become more prominent. Since the COVID-19 pandemic has greatly affected the service sector (Xiang et al., 2021), services that use IT in their operations can be more successful. It can be helpful in different operations such as training employees (Elhazzam, 2015), financial issues (Alshubiri et al., 2019), customers (Shahzad et al., 2020), etc.
The service sector is a rapidly growing area of the global economy, and in the COVID-19 pandemic situation, healthcare organizations play an essential role in this growth. With the development and expansion of information technology (IT) the healthcare market has become a competitive environment, and the number of hospitals in Iran has increased (Doshmangir et al., 2019). To survive in competitive environments, organizations should consider customer satisfaction, which is the most fundamental issue for them.
In today's world, the issue of quality has challenged organizations’ management, and its acceptance in the service sector has increased. Service quality is an essential factor for the growth, success, and viability of the organization, and as an effective and comprehensive strategy, it is on the agenda of top management. Traditional attitudes have defined quality based on product or service characteristics (Kim-Soon et al., 2014; Kumar & Palmieri, 2010), while new practices and perspectives define quality as customers’ needs (Bedane & Mohammed, 2021). Therefore, successful organizations seek to meet their customers' wants and needs.
Health as a complete physical, psychological, and social well-being is intricately linked to other political, social, economic, cultural, and technological fields. Due to the increasing complexity of various aspects of development and the Covid-19 pandemic, the provision, maintenance, and promotion of health have become the central concern and challenge of policymakers, decision-makers, and the public in countries. If the countries' health is enhanced, their development will undoubtedly be improved and sustained. In 2016, the United States spent 17.8% of its Gross domestic product (GDP) on health care; however, only about 19% were satisfied with healthcare quality (Papanicolas et al., 2018). Statistics also show that 40 to 70% of health budgets are allocated to hospitals (Fakhri & Aslipoor, 2015).
As one of the large and complex service organizations and an essential service provider in the health system, the role of hospitals is very prominent. Due to the high risk of the hospital’s services, the services provided must be of superior quality. Also, due to the fierce competition and complexities of the business environment, service providers must provide quality services to maintain their survival and profitability and achieve sustainable competitive advantage (Adel et al., 2011). Hospitals are responsible for supporting primary care services in the health system, without which the health system would not be complete in providing quality and effective care. Hospitals' primary mission is to provide quality care for patients and meet their needs and expectations. Achieving this mission requires the institutionalization of quality in hospitals.
Patient satisfaction with hospital service is one of the leading indicators of the efficiency and effectiveness of services provided by different hospital wards. A satisfied patienttheis a key to any hospital's success. It is noteworthy that knowing the client's expectations is the first step in improving the health service quality. Quality is the customer's desire, and their perceived expectations determine the quality (Aghamolaei et al., 2014; Bedane & Mohammed, 2021; Sharma & Gadenne, 2001).
Employee activities in service organizations are a determinant factor in developing effective customer relationships. Therefore, employees' skills, attitudes, and behaviors are critical in this area because medical staff are responsible for providing quality services that meet customer expectations (Suleiman Awwad & Mohammad Agti, 2011). Due to the competitive environment in service organizations and increasing customer awareness of the services provided by these organizations, customer expectations are ever-increasing. Therefore, service organizations need to provide customers with quality services to retain them.
Satisfaction is essential in health care systems because the disease experience and the need to follow the treatment and care process increase patients' vulnerability and intensify their need for comprehensive support. However, in recent years, changing social conditions and increasing public awareness have also raised patients' expectations of receiving services (Sadeghi et al., 2021).
Patient relationship management (PRM), in addition to customer relationship management (CRM), can create a long-term two-way relationship between patient and hospital. Having skilled staff to deal with the patients can lead to customer loyalty and improved health. Implementing a PRM system enables patient retention and profit, and reputation promotes community health (Meskarpour-Amiri et al., 2021).
A growing number of healthcare centers are equipped with IT have increased competition for patient admissions, and as a result, hospitals have implemented models to improve patient satisfaction. Today, hospitals need to develop close relationships and PRM and provide optimal service and care environments through innovative technologies for enhancing patient satisfaction (Poku et al., 2017). Combining the Kano model and quality function deployment (QFD) helps organizations design services or products according to customers' desires and wants, thereby providing the highest customer satisfaction. The main philosophy of the QFD technique is to apply customer demands in product or service development. Therefore, all product/service design specifications are obtained according to the consumer’s point of view. It is noteworthy that the role of experts in the design of a new product and service is nothing more than a translator. These translators use QFD to convert customer demands into quantitative specifications (Koleini Mamaghani & Barzin, 2019).
To the best of our knowledge, previous research has not conducted a detailed study of significant factors for hospital service quality considering IT. Therefore, for responding effectively to customers and their maximum satisfaction, which is the main factor for gaining a competitive advantage, this study first tried to identify the determinants (needs) of hospital service quality using experts’ opinions and relevant literature review, and then categorize these needs using the Kano model. After sorting the needs into three categories named “Basic”, “Functional”, and “Motivational”, the basic needs’ relative importance was computed using the AHP method. Next, some solutions were provided for basic needs that seemed to play a significant role in increasing customer satisfaction and loyalty.
Literature Review
In the traditional approach, objective criteria such as mortality rate and disease prevalence were used to assess health service quality. However, these criteria are now primary tools to evaluate clinical service quality. Today, subjective measurements are more common. As a result, healthcare service providers are trying to use customer-centric assessment tools, since the role of patients in defining service quality is becoming more apparent. Also, patients’ needs change over time. Hence healthcare service providers should be aware of patients’ needs and satisfy them. In the COVID-19 pandemic situation, effective use of IT can help healthcare systems to attain better service quality. Service quality is recognized as a critical determinant of organizational success in today's competitive environment, and it is worrying when customer satisfaction declines because of poor service quality (Zaim et al., 2010). For a better understanding of the concepts in this paper, the following definitions are presented:
IT: The term “Information Technology” refers to any technology that assists humans in creating, altering, storing, or transmitting information. Computers, telephones, televisions, cell-phones, and other electronic devices are examples of information technology. (Sihombing et al., 2020).
Service: Service is a process involving a series of intangible activities that occur naturally in customer-employee interactions to provide solutions to customer problems (Kasim et al., 2018).
Quality: Quality is a measure of excellence. Quality has no meaning but what the customer wants. In other words, a product or service is of high quality when it meets customers’ wants and needs (Bedane & Mohammed, 2021; Madu & Madu, 2002).
Service quality: Service quality consistently complies with customer expectations and knowledge of a particular service. Therefore, it can be acknowledged that service quality is a judgment that customers make based on their perception after a service delivery process (Büyüközkan et al., 2011; Stefano et al., 2015).
What differentiates quality in the healthcare sector from other sectors is that patients and medical staff do not think of quality in the same way. As mentioned, the medical staff defines quality as doing the right thing at the right time and doing it right from the first time. Patients judge quality differently. Studies have shown that patients measure quality based on their values. Health service quality consists of technical quality (outcome quality) and functional quality (process quality). Technical quality focuses on the accuracy of physician procedures and diagnoses, and functional quality refers to how healthcare service is provided to patients. Since most patients lack the knowledge needed to evaluate the technical quality of services, their quality assessment is based on the medical care process (Lam, 1997; Lin et al., 2004; Zarei et al., 2012). The medical care process includes five essential steps: collecting subjective and objective information about the patient; gathering and evaluating data to identify problems and set priorities; designing an evidence-based and cost-effective care plan; implementing the care plan, and monitoring the patient during follow-up encounter to evaluate the plan's effectiveness and modify it as necessary (Haines et al., 2017).
Using health information technology, these steps can be performed in higher quality and consequently satisfy patients. Information technology in hospitals can aid in training employees, maintaining records, managing data, and making informed decisions (Pezaro & Lilley, 2015).
Several studies have been conducted on hospital service quality due to the growing importance of services in advancing organizational goals and increasing customer satisfaction with services. Purcărea et al., (2013) sent a SERVQUAL questionnaire to 1,000 Romanian women’s e-mail and concluded that because most healthcare clients lack the necessary know-how, they try to measure services in terms of tangibles such as environment and price.
In their study "Survey on Nursing Service Quality by SERVQUAL at Tehran Social Security Organization Hospitals," Mohammadnia et al., (2010) reported the service quality of the selected hospitals at a reasonable level. This study showed that reliability, assurance, and empathy had the highest quality, and responsiveness had the lowest quality.
A case study by Ozturkcan et al., (2009) confirmed the effect of hospital service quality at Marmara University on customer satisfaction and loyalty. A study in Egyptian hospitals showed that patients' expectations of hospital service quality affected their satisfaction with services and hospital type (private or public) selection (Mostafa, 2005). Another study showed the relationship between healthcare providers’ communication skills and patient satisfaction (Boissy et al., 2016).
A study in Canada examined the relationship between hospital health information technology and patient satisfaction. The study showed that full implementation of health information technology in hospitals can lead to significant improvement in patient satisfaction (Roham et al., 2012).
Materla et al., (2019) used the Kano model-based questionnaire over 138 patients to identify diverse patient needs and aims to eliminate the gaps identified in prior research. Singh & Prasher, (2019) integrated fuzzy set theory into SERVQUAL, and AHP to measure the service quality of four hospitals in India and ranked them based on patients’ perspectives. Sinha et al., (2013) combined SERVQUAL and QFD to identify the success factors to improve the quality of the healthcare industry. They found that better behavior and attitude of staff results in a higher quality of the hospital. They also find a strong relationship between the behavior and attitude of staff and having enough modern technology.
To the best of the authors’ knowledge, there is not any study that applies AHP, QFD, and the Kano model to identify patients’ needs and provide solutions considering information technology to meet their expectations. Therefore, in this paper, the researchers addressed this issue.
Kano model
In 1984, Professor Noriaki Kano et al. introduced the Kano customer satisfaction model, distinguishing between three types of product needs affecting customer satisfaction in diverse ways. The Kano model divides each product's quality needs and characteristics into three categories, each representing a specific customer need to be expected to exist in the product. These three types of requirements are:
Basic requirements: The first category of qualitative characteristics are the basic needs that exist implicitly. In other words, they are compliant with standards, i.e., minimums, which prevent customer dissatisfaction. In the other words, customer dissatisfaction will be high if they are absent or perform poorly (Materla, Cudney, & Antony, 2019).
Functional requirements: The second category of quality characteristics are the functional needs of the product/service. The customer clearly expresses these needs, and their fulfillment leads to satisfaction, and their failure leads to dissatisfaction. For example, a car's warranty and reasonable price fall into the functional requirements (Paraschivescu & COTÎRLEŢ, 2012; Sauerwein et al., 1996).
Motivational requirements: These needs are product features that significantly impact how a customer is satisfied after receiving the product. These needs are never explicitly stated by the customer or expected. Fully meeting these needs will further enhance customer satisfaction. If the customer does not receive them, they will not feel dissatisfied. Observing these features makes the company a market leader (Azizi & Aikhuele, 2015). The Kano model is shown in Figure 1.
The Kano questionnaire is a tool for categorizing customer requirements in the Kano model, and the items in this questionnaire are designed as two-dimensional items for each feature. Kano uses a simple method of positive and negative items to understand and identify customers’ quality needs. The first item (positive aspect) is a person's reaction to a feature in a product or service. The second item (negative aspect) also indicates the person's response to not considering the same feature in the product or service (Sauerwein et al., 1996; Witell et al., 2013). The product or service features can be classified by collecting two-item answers in the evaluation table. Table 1 shows how customer needs are assessed and ranked based on this questionnaire.

Analytic Hierarchy Process method
Analytic hierarchy process (AHP) presented by (Saaty, 1988), is a multiple-criteria decision-making method and one of the most extensively used and powerful methods to solve complex decision problems. AHP is a very significant approach to MCDM (Solangi et al., 2019). In the AHP method, the pairwise comparison is operated in a matrix used to evaluate and prioritize the basic needs of patients. The AHP process can be elaborated as follow:

The experts’ consolidated opinions are taken in terms of pairwise comparisons of the selected needs. The pairwise comparisons are done using Likert’s five-point scale (1, 2, 3, 4, and 5 points in the scale represent Equally-, Moderately-, Strongly-, Very strongly-, and Extremely-important). The AHP method allows some small inconsistencies in opinions because humans’ opinions are not always consistent. The ratio scales are derived from the principal Eigenvectors and the consistency index is derived from the principal Eigenvalue. We construct a pairwise comparison matrix using Likert’s five-point scale. Considering n needs, the pairwise comparison of need with need yields a square matrix where denotes the comparative importance of need with respect to need for . In the matrix, , when and .

For this case, a group of 50 patients involved in the collecting data process were asked to give their opinions on the relative importance of the needs, and the highest frequency of opinions were considered for evaluation. Their opinion/relative importance grading was used to form the square matrix (A).
We calculate the normalized matrix by summation of each column and then dividing each element by the respective column total, where element is the:
Next, we calculate the mean of each row to obtain the normalized principal Eigen vector i.e., or . Here, several iterations are done by squaring the normalized matrix till the difference in principal Eigenvectors in previous and iterated matrix becomes almost zero or negative. This final iterated matrix gives the principal Eigenvector (or priority vector), which is the weight of each need. The principal Eigenvalue of the matrix A must be calculated, and it is called . It is calculated by multiplying the column sums of matrix A with the principal Eigen:
Quality function deployment model
The QFD model falls into the category of quality management models and proposes a linear and structured strategy to return customer needs to the features of new products or services. The model involves the development of four matrices or the so-called House of Quality (HoQ) (Bevilacqua et al., 2006; Ramírez et al., 2017).
The measurable objectives of applying the QFD model can be summarized as follows: lower cost design, elimination of frequent technical changes, preliminary identification of critical production locations, determination of processes ahead for production, significant reduction of product development time, more efficient resource allocation, adjustment of design quality and planned quality, analysis of market quality information, reduction of development costs, and increased market share (Han et al., 2001; Mohanraj et al., 2011; Vinodh & Rathod, 2010).
The HoQ has helpful content that can be the endpoint of many QFD projects if accurately prepared and adjusted while providing valuable information about the product or service. Straightforwardly and tangibly, the HoQ can be considered as a matrix of customer needs (WHATs) and technical or engineering specifications (HOWs) (Wang & Chin, 2011). Each HoQ has six sections: customer requirements, planning matrix, technical requirements (HoQ’s roof), relationship matrix, balanced matrix, and targets.
This study identified 18 needs to measure hospital service quality indicators based on experts' opinions. These needs are shown in Figure 2
Methodology
This is a descriptive survey. In this regard, based on the experts’ opinions and related works, a total of 18 key performance indicators (KPIs) were identified and determined to evaluate the quality KPIs of hospital services. These components were determined based on similar studies and interviews with academic and hospital experts. The components list is shown in Figure 2. In this study, to identify the basic, functional, and motivational needs, the Kano model was used, in which, 18 KPIs were presented once as desirable and once as unfavorable, resulting in a questionnaire containing 36 questions. After the Kano model and KPIs classification (7 needs), which are a crucial factor in gaining a competitive advantage for companies and organizations, their relative importance was determined using the AHP technique. These needs were then considered as input to the QFD model. Finally, after analyzing the QFD model due to the organization's limitations in solving all of them, the Pareto model was used to solve 20% of the organization's problems, creating 80% satisfaction, which was calculated using Minitab software.
The framework for conducting the present study is shown in Figure 3. In the first step, KPIs (needs) related to the quality of hospital services were identified. In the second step, using the Kano model, the identified needs were divided into three categories: Basic, functional, and motivational needs. In the third step, using the AHP technique, the significance of the basic needs categorized in the previous step was calculated. In the fourth step, the basic needs were considered as the input of the QFD model, the solutions to meet the required needs were identified using experts’ opinions and the final weight of each solution was calculated. Since the organization's resources are limited and there are many ways to meet these needs, the Pareto technique was used to meet 20% of the needs and obtain 80% satisfaction. The statistical population of the study included all patients of the Hospital and Medical Center. To determine the statistical sample, since difficult access to patients, a limited number of 50 patients were randomly selected to collect the required data.
The data required for this study were collected for the Kano model using a questionnaire. The questionnaire included 6 dimensions and 35 items related to service quality. Since the questionnaire was identified based on the quality of the services and provided from the experts’ perspective, and the final version of the questionnaire was approved by several experts, the content validity was confirmed. Frequency of data collected is shown in TABLE 2. Confirmatory factor analysis was used to evaluate the construct validity of the research variables measurement tool. The results confirmed the construct validity of the model for measuring the quality of patient relationship management services. Furthermore, Cronbach's alpha method was used to calculate the reliability. Using SPSS software, the reliability of this questionnaire was estimated to be 0.902. It is worth noting that since the Cronbach's alpha was greater than 70 %, the reliability of the distributed questionnaire was approved.

Results and Discussion
The collected data were first analyzed based on the Kano model using Excel software, for which the weighted mean frequency method was used. In this method, the frequency of three basic, functional, and motivational needs was computed. In this method, the basic needs got degree 1, functional needs recived degree 2, and degree 3 went to the motivational needs. Then the weighted average of each need was calculated based on Equation 2.

As mentioned earlier, the alphabet B indicates basic needs, alphabet F indicates functional needs, and M indicates motivational needs. The alphabet I (Indifferent) stands for times when the customer is almost discouraged by the presence or absence of a need in the product. Q (Questionable) indicates when the customer did not understand the question, or the information was incomplete. R (Reverse) occurs when the observance of a feature is expressed in a desirable way and its non-observance is expressed in an undesirable way. Table 3 shows the weighted average of needs identified.

Figure 4. shows the categorized needs. The classification of needs, in this figure, was done based on the following logic: Needs that gained more than 1.4 were considered as the basic needs. Needs that scored between 1.2 and 1.4 were identified as the functional ones. Needs that scored less than 1.2 were regared as the motivational needs. Based on the results of Figure 4 the basic needs include:
These needs were the primary concern of patients. Interestingly, given the prevalence of the coronavirus, answering patient questions online was considered a basic need.
Figure 4. Needs classification based on Kano model
By identifying the basic needs, the relative importance of these needs to enter the QFD model was calculated based on the AHP technique using Expert Choice software. The significance coefficient of these needs is shown in Figure 5. AHP is a prime approach as it enhances decision-making learning using the consistency measure (Olson, 1988). AHP method is an approach of MCDM, which analyzes the problem displayed in different levels of hierarchy. This technique has the strength to determine quantitative and qualitative factors using a pairwise comparison matrix (Solangi et al., 2021). After weighing and determining the importance of basic needs using the AHP method, solutions to improve and meet these needs were provided using experts’ opinions and literature review. These solutions are as follows:

The QFD model can be drawn and analyzed in several ways. In this research, only the quality house matrix is created by QFD 2000 software, and its analysis is summarized in Table 4. As can be seen in Table 4, customer demands are the same as the basic needs of the Kano model; but the technical requirements are how to meet the 7 needs requested by the customer. Because the organization's resources are limited and the ways to meet these needs are numerous, the Pareto technique has been used. Pareto law considers 80% of disabilities to be due to 20% of causes. According to this principle, paying attention to this 20% can have the greatest impact or improvement in 80% of the satisfaction. In this regard, this step was done using Minitab software and the results are shown in Figure 6.
The results of the Figure 6 show that the hospital can achieve the highest satisfaction with the least action by implementing the 8th and 1st solutions (Holding ethics training courses online and Creating team spirit and using health information technology in the hospital).

Conclusion
The hospitals' role as one of the most important service providers for people who seek healthcare and medical services is very prominent (Hussain et al., 2019). Hospitals should consider their service quality to overcome patients’ needs and boost patients’ satisfaction; since their satisfaction is tied to service quality (Zaman et al., 2021). The continuous revolutionary effect of information technology on services has changed the importance of these needs. Therefore, hospitals should take specific actions to improve their performance and provide high-quality services considering the effect of health information technology on their outcomes (Pai et al., 2022) and the intensity of competition among them.
According to the purpose of the research and to present a novel approach in service quality studies, Kano, AHP, QFD, and Pareto techniques were used in combination. The method used in this research can offer the hospitals’ administrations better insights to improve their services. In the first step, the most important and vital needs (basic needs) were identified using the Kano model, which are as follows: online announcement of the exact time of performing services to the patient, 24×7 availability of hospital services, answering patient questions online, courteous and friendly behavior with the patients, the staff sincere concern for the patient, paying attention to the patients’ feelings and emotions, and performing services in compliance with contractual responsibilities. The importance of indicators in the model was weighted based on the AHP method. As part of this step, experts presented solutions (strategies) to meet these needs.
These solutions were ranked using QFD 2000 software. Since hospitals are not able to meet all these needs, the Pareto technique was used to create 80% satisfaction by satisfying 20% of the leading solutions. Finally, the strategies of “holding ethics training courses online” and “creating team spirit and using health information technology in the hospital” were selected. The obtained results of the current study were previously approved by other pieces of research such as the studies conduted by Camgöz‐Akdağ, H., Tarım, M., Lonial, S. and Yatkın in 2013, the one by Meesala & Paul in 2018, and that of Roham et al. in 2012. For instance, Camgöz‐Akdağ et al., (2013) concluded that employee conduct and attitude have the greatest effect on hospitals’ performance which improves their quality by about 25 percent. Holding online ethics training courses for staff members, especially during the pandemic when remote working was popular among employees, improved their attitude and behavior toward the patients. Roham et al., (2012) found that the complete deployment of health information technology in hospitals enhances patient satisfaction i.e. it can improve the quality of hospital services. Reliability and responsiveness, which are pertinent to creating team spirit and using health information technology in the hospital, can enhance patient satisfaction (Meesala & Paul, 2018).
Despite all contributions mentioned in this work, some suggestions for future research are presented below:
Given the limited access to patients, according to which a limited number of 50 patients were selected as a statistical sample, it is suggested that future researchers increase the volume of the statistical sample to achieve more comprehensive results.
Since the house of quality was divided into 6 main parts and the driving force of the whole QFD process is patients' needs, and due to the increasing needs, it is recommended that the needs be grouped by statistical techniques such as factor analysis and cluster analysis and then the finalized groups enter the quality house matrix. This will make the research results more complete. Given that the Kano model only shows the importance of needs, it is suggested that in future research, the desired results be achieved using the importance-performance matrix.
