Regarding to the importance of customer satisfaction, the study drives its interest towards quality of hotline services in Vietnam A case study is explored through Ministry of Health’s hotline services It is notable that health service is booming in Vietnam The study is aimed to identify current performance of hotline services offered
by the Ministry of Health and how current performance influencing on customer satisfaction The research questions therefore will be:
- What are the impacts of determinants to customer satisfaction in handling feedbacks in Ministry of Health’s hotline service?
- What are recommendations to further improve effectiveness of handling feedbacks in Ministry of Health’s hotline service?
There are many research strategies that are being used in academic studies, including survey, interview, case study, ethnography, grounded theory, or historical documents In this study, survey strategy will be used as main research strategy The author would like to collect primary data from 100 respondents and the first data analysis is conducted to clarify their demographic information, including gender, age, place of work, and period of using services The next data analysis refers to reliability test and it comes up with 3 requirements The first requirement refers to calculation of Cronbach’s Alpha and expected value is higher than 0.6 The second requirement refers
to Corrected item-total correlation and the value must be higher than 0.3 The last
Trang 4requirement refers to calculation of Cronbach’s Alpha if one variable is deleted and expected value should be lower than Cronbach’s Alpha which is obtained in first requirement checking
Some conclusions have been made from the thesis First, descriptive statistics is conducted with mean value calculation for each variable used in survey of questionnaire.Second, reliability test and EFA test are conducted to check reliability and validity of the survey item.Third, ANOVA analysis shows that there are no difference among the respondents who have different demographic characteristics in term of customer satisfaction and customer service effectiveness Fourth, multiple linear regressions are conducted for two pair of causal relationship
From above conclusions, the author recommends that the companies need to consider the importance of treating customers politely Moreover, the companies need
to consider the importance of service capacity as it has highest influence on customer service effectiveness Furthermore, the Ministry of Health should develop specific indexes to measure customer satisfaction with hotline services in specific and overall services in general.Finally, the Ministry of Health must align hotline service performance with all branches and subsidiaries in provinces

1.1Urgency of the topic
Customer satisfaction is playing prominent role in almost firms today It is also considered as strategic weapon and contribution much into firms’ successes Generally, customer satisfaction brings many positive effects to firms such as higher repeat purchases from the customers, selling products or services at higher prices (Sheth, 2001) It is notable that higher repeat purchases from the customers is assured from higher customer purchasing intention and customer retention rate when they get satisfaction with product or service performance (Lemon et al., 2002; Bolton, 1998; Rust and Zahorik, 1993) Empirical evidence from Dawkins and Reichheld (1990) shows that customer satisfaction helps to increase profit of the firms by more than 25%
In addition, customer satisfaction is more important than discounted prices (Gupta et al., 2004)
Customer satisfaction establishes the evidence to sell product or service even at higher prices than averages in the market (Sheth, 2001) Empirical evidence from shows that higher price setting and customer satisfaction is associated with each other (He et al., 2008) Moreover, when customers get satisfaction with product or service, they are likely to become loyalty customers and it is critical requirement during crisis period (Nelson et al., 2009) Report from The Institute for Working Futures (2012) indicates that loyalty customer remains purchasing volume and therefore the firms have more opportunity to survive throughout this period Another benefit of customer satisfaction
is generated from positive word-of-mouth (WOM), as cited by Oliver (1997) It is denoted that WOM is a process whether satisfied customers provide positive comments about product or service quality to their friends or family members and therefore the firms have more opportunity to sell product or service to potential customers (Ha and Janda, 2008) Moreover, WOM allows the firms not too much spending to advertising efforts and therefore operating cost is saved and profit margin is higher (Khraim, 2011) Customer satisfaction is important to the firms due to satisfied customers often provide feedbacks about product or service quality (Keller and Libai, 2009) It is useful ideas and realistic evidences for further improvement or even higher innovation in new product or service design (Someshwar et al., 2001)
Trang 10Regarding to the importance of customer satisfaction, the study drives its interest towards quality of hotline services in Vietnam A case study is explored through Ministry of Health’s hotline services It is notable that health service is booming in Vietnam
Figure 1 Health Expenditure per capita US$
Source: World Bank (2017)
The report from World Bank (2017) shows that total health expenditure per capita by US$ in Vietnam increases continuously from only US$14 in 1995 to US$142
in 2014 However, this number is much lower than global average which is stood at US$1,060 in 2014 (World Bank, 2017) Compared to other countries in ASEAN like
142 1,060
Vietnam vs World in Health expenditure per
capita (current US$)
456 2,752
Vietnam vs Thailand vs Malaysia vs
Singapore in Health expenditure per capita
(current US$)
Trang 11Thailand, Malaysia, and Singapore, health expenditure per capita by US$ is two times lower than Thailand and three times lower than Malaysia Singapore is the country which has highest health expenditure per capita by US$ in ASEAN with value of US$2,752 (World Bank, 2017)
Another insight about Vietnam healthcare services is explored through recent report from Gaskill and Nguyen (2016) This report indicates that Vietnamese people has been spent more than US$12 billion for healthcare services and this number has consumed about nearly 7% of total national Gross Domestic Product (GDP) Moreover, Vietnam’s healthcare system is characterised by public and private groups It is notable that Vietnamese people are still spending a lot of their owned money to higher healthcare services quality (Angloinfo, 2017) It leads to a critical role of Ministry of Health in term of providing adequate governance as well as national programs to further improve healthcare system in Vietnam and allow Vietnamese people to have adequate accessibility to healthcare services
Regarding important role of Ministry of Health, it is observed that hotline services is important activities whether the employees mustreceive and answer many calls to question about current healthcare policy It raises the concern of lower efficiency and effectiveness in hotline services lead to reduction of customer
satisfaction In this context, the study is developed with topic “A study of survey on
enhance customer satisfaction by handling feedbacks – The case of the Ministry of
Health’s hotline.”

Trang 132 LITERATURE REVIEW
2.1 Customer satisfaction
Customer satisfaction is strategic weapon that lead to business success in case of
it is being maintained well (Nguyen, 2012) Moreover, customer satisfaction is determined as important theoretical and practical issue in modern management and marketing studies (Jamal and Naser, 2003) It is notable that the concept of customer satisfaction is provided differently by different researchers over the time (Oliver, 1997) The concept of customer satisfaction is generally abstract and therefore it consists of much arguments (Olsen, 2002)
The simplest definition of customer satisfaction is provided by Oliver (1997) whether it is defined as customers’ reactions given to the qualification of service quality
to customers’ needs and demands Before that, Yi (1990) define customer satisfaction is combined between actions and psychological responses of customers after they have actual experiences with products or services Gunderson et al (1996) assert about customer satisfaction as post-consumption judgment of the customers upon on specific attributes of products or services Next, Tse and Wilton (1998) define customer satisfaction as how they response to actual performance of products or services given to their expectations prior purchasing decisions are made up Cacioppo (2000) views customer satisfaction as state of mind of customers and it reflects level of accomplishment of products or services towards their needs and demands Kotler (2001) also provide another idea of customer satisfaction as his/her feelings which are derived from perceived product or service quality and actual performance Kathleen (2005) indicates about customer satisfaction as his/her needs, wishes, expectations, and desires
in term of products or services fulfillment
2.2 Hotline service
Hotline service is defined as telephone-based service which is provided by firms
to support the customers given to range of services offered (Zeiss, 2000) In more detail, hotline service helps to deliver following services First, hotline service provides telephone consultant and support to customers related to firms’ commitment Second, it
Trang 14is established with the objective of analysing customers’ problems occurring during the time of using services Third, hotline service reduces negative effect from wrong uses or operating errors Fourth, hotline service is often available 24/7 and it even handles customers’ questions during weekends
In addition, operational framework of hotline service is provided and evaluated
by Zongling (2014) Generally, hotline service refers to information flow from customers to operators of firms This information flow is illustrated as in the figure below:
Figure 2 Information flow in hotline service
Source: Zongling (2014)
Figure 2 shows that hotline service consists of information as input The source
of input comes from enquiry acceptances such as telephone, short message service (SMS), and email Information which is collected from input stage will be put into processing stage whether direct solutions are provided In some cases, it is necessary to make enquiry transfer to functional units or need participation from supervisors Next, output stage is highlighted as information dissemination to the enquiries or customers It
is notable that one enquiry is not resolved for the first time and therefore it leads to the requirement of follow-up based on the result
As cited by Zongling (2014), hotline service quality is often evaluated through value drivers In case of Jinan 12345 Hotline Service, Zongling (2014) emphasises three most important drivers, including service efficiency, service quality, and service costs
Trang 15Hotline service efficiency is determined through the number of enquiries accepted by one operator per day and how much time to process one enquiry Hotline service quality
is second value driver and it is established to measure the rate of timely resolved enquiries, service level and service attitude, and customer satisfaction Service cost is last value driver and it measures direct cost involved into enquiries management and solving The cost may include equipment cost, staff cost, and management cost
2.3 Customer service effectiveness
Customer service effectiveness is defined as how effectively a company’s
service satisfy its customer; or whether customer’s demands and needs have been met yet (Marina, 2017) The truth is even when you feel that your business is running well,
it is not proved that your customer is feeling happy as well Therefore, it is crucial to have some ways to measure your effectiveness by measuring your company’s customer-services effectiveness By doing that, the entrepreneur may find out which department
or area needs to be improved
Although there are a lot determinants of customer service effectiveness, the major factors refer to convenience perception, service capacity, customer service, and resolving complaints (Tran et al., 2016)
Convenience perception is defined as a set of things that are provided by the companies or the suppliers to ensure that offered services are useful, convenient, and easy to use to the customers (Laitamaki et al., 1997) During the time of using services, the companies need to ensure service capacity at proper level Service capacity is defined as the qualifications when services are delivered to the customers (Tran et al., 2016) Service capacity addresses the importance of provision of which the employees can serve the customers as well as system support to capture information during services to be delivered (Tran et al., 2016) It is notable that service capacity addresses the assurance aspect of a service and it is strictly required to keep the customer service effectiveness and customer satisfaction at proper level (Cronin and Taylor, 1992) Moreover, when the companies deliver services to the customers, they must ensure that customer service is delivered at right direction (Tran et al., 2016) Customer service is defined as after-sale services or additional activities to be conducted by the companies
in the way of maintaining customer satisfaction and customer experiences (Zeithaml, 1993) Customer service also highlights the value of interaction between the customers
Trang 16and the companies’ employees related to specific characteristics or performances of services (Tran et al., 2016) As cited by Boulding (1997), customer service is part of corporate culture of the companies The last determinant of customer service effectiveness refers to how the companies can handle customers’ complaints or resolving complaints It is “a set of steps in the process as collecting information, receiving feedback, appeasing the anger of customers, analyzing the complaint and determining the remedial action, applying skills in communication etc to convince customers or deal with all the issues, including really stressful situations.” (Tran et al.,
2016, pp.18)
2.4 The relationship between customer service effectiveness and customer satisfaction
It is notable that customer service effectiveness contributes directly and largely
to customer satisfaction level towards the companies’ products or services (Tram et al., 2016) In attempt to satisfy customers, the companies today need to pay attention to customer service and its effectiveness to bringing delight to customers during the time they utilise product or service of the companies (Solomon et al., 2015) In this context, many studies are delivered with high concentration on customer service effectiveness and it is highlighted in many marketing literatures as it contributes largely to the survival of businesses (Beny, 1995; Morgan and Hunt, 1994; Sheth and Parvatiyar, 1995) As cited by Kotler (2012), customer service is center or it is considered as strategic weapon that helps the companies to compete with other competitors from the markets as well as putting customers at the center of the companies’ activities with the objective of leveraging customer satisfaction level The study of Peng and Wang (2006) indicates that customer service must be maintained frequently and its effectiveness must
be measured to ensure that customers are delight with current product or service and higher level of customer service effectiveness reflect the strength in commitment between the companies and their customers in long term In addition, the companies who perceive about the importance of customer service always provide in-time actions
to maintain customer service at proper level and they often nurture and maintain a healthy balance between the companies’ benefits and customers’ benefits (Solomon et al., 2015) Moreover, when the companies provide adequate attention and high quality
in customer services, they gain the benefit of customer retention (Kerstetter, 2001;
Trang 17Reinartz and Kumar, 2002; Winer, 2001) One of the most important part in customer service is to understand the relationship with customers and the relationship is maintained throughout the understandings of the cultural dimension of each customer or each group of customers (Solomon et al., 2015) The practice has become such an important standard in modern business that it is common for businesses to establish some loyalty incentives and programs for maintenance, nurturing and keeping a healthy customer relationship (Kotler, 2012)
2.4 Research Structure and Hypothesis
From the discussion of determinants of customer satisfaction, a research structure is developed as below:
Figure 3 Research Structure
From this research structure, research hypotheses are stripped;
H1: Service capacity has positive impact to customer service effectiveness
H2: Convenience perception has positive impact to customer service effectiveness
H3: Resolving complaint has positive impact to customer service effectiveness
H4: Customer service has positive impact to customer service effectiveness
H5: Customer service effectiveness has positive impact to customer satisfaction
Trang 183 RESEARCH METHODOLOGY
3.1 Research philosophy
Research philosophy reflects belief of the researchers regarding to specific social phenomenon (Saunders et al., 2009) Currently, there are many types of research philosophy, including positivism, interpretivism, realism, and pragmatism (Saunders et al., 2009) However, positivism and interpretivism are dominating in academic studies (Levin, 1988) Positivism research philosophy is belief of researchers to carry out their studies with scientific or objective observation (Gephart, 1999) while interpretivism research philosophy is determined as the adaptation of empathetic stances to get in-depth understandings of social phenomenon (Kura, 2012) In this study, positivism is chosen as main research philosophy
The reason of choosing positivism research philosophy is that positivists seek for causal relationship between dependent and independent variables (Lewis, 1993) This study aims to measure causal relationship between customer satisfaction and its determinants in hotline services in Ministry of Health Another reason is that interpretivism is mostly based on subjective argument from the researchers (Remenyi et al., 1998) In this context, key findings under interpretivism are not objective or higher bias than what are found in positivism research philosophy (Mitchell, 2003)
3.2 Research approach
There are two research approaches, including deductive and inductive (Robson, 2002) Major differences between deductive and inductive research approach are highlighted from the fact that deductive research approach is based on existing theories related to social phenomenon while inductive research approach is utilised to create a new one (Anderson, 2004) Another difference between deductive and inductive research approach is that deductive approach aims to clarify causal relationship among variables while inductive research approach obtains the fact through content analysis (Collis and Hussey, 2003) In this study, deductive research approach is utilised instead
of inductive research approach
The reason of choosing deductive research approach is that this study starts with existing theories and concepts related to customer satisfaction in hotline services Then,
Trang 19empirical evidences are collected from previous studies and the result refers to the choice of explanatory factors towards customer satisfaction On the other hand, it means that the study seeks for causal relationship between customer satisfaction and its determinants As cited by Lewis (1993), causal relationship is first sign of using deductive approach Another reason of using deductive research approach is that it is processed quicker than inductive research approach (Saunders et al., 2009) In addition, the researchers who follow inductive research approach may face up with higher failure
in establishment of new theories (Saunders et al., 2009) Finally, deductive research approach will be utilised when studied topic is common (Creswell, 1994) This study aims to study about customer satisfaction and it is very common topic
3.3 Research strategy
There are many research strategies that are being used in academic studies, including survey, interview, case study, ethnography, grounded theory, or historical documents (Saunders et al., 2009) In this study, survey strategy will be used as main research strategy Case study is chosen due to following reasons First, survey strategy
is utilised when deductive research approach is conducted (Saunders et al., 2009) Moreover, survey strategy helps the researchers to evaluate quantitative impacts from independent variables to dependent ones (Saunders et al., 2009) Second, survey strategy ensures that primary data is collected adequate sample size and therefore it reduces times and efforts to collect subsequent data (Saunders et al., 2009) Finally, survey strategy is being used widely in academic studies and it allows the researchers to collect sufficient information for later data analysis; thus, key findings are not subjective accordingly (Saunders et al., 2009)
3.4 The choice between quantitative and qualitative
There are two research methods, including quantitative and qualitative (Saunders et al., 2009) They are different to each other in term of data collection and data processing Quantitative research method aims to collect numerical data from survey of questionnaire and data processing refers to mathematical or econometrical calculation (Saunders et al., 2009) In the contrast, qualitative research method relies on non-numerical data which is often collected from opened interviews with relevant respondents (Denzin and Lincoln, 1994) Moreover, qualitative research method is
Trang 20deployed with content analysis and it is not relied on data analysis techniques (Biggam, 2008) In this study, quantitative research method will be utilised in this study
Quantitative research method is chosen due to following reasons First, the study
is developed under positivism research philosophy and quantitative research method is subsequent choice (Saunders et al., 2009) Second, quantitative research method helps the researchers to measure quantitative impacts from determinants to target social phenomenon (Crisp, 1957) Third, quantitative research method is relevant to the researchers who are concerned with measurements or they want to deploy mathematical evaluation to obtain objective findings (Biggam, 2008)
3.5 Data collection
There are two types of data that will be collected in this study, including primary and secondary data Primary data is collected from survey of questionnaire or interview with respective respondents who are linked to target social phenomenon (Srivastava and Rego, 2011) The advantage of primary data is that it directly links to research objectives and research questions (Saunders et al., 2009) In this study, primary data will be collected from survey of questionnaire and it is designed in well-structured approach
Secondary data refers to the information that existed in previous studies or reports (Saunders et al., 2009) The advantage of secondary data is that it does not consume much time and much effort to collect due to the researchers can find relevant information from many sources such as the Internet and books in libraries (Srivastava and Rego, 2011) Moreover, secondary data is ready to use as it is prepared and processed by previous researchers (Stewart and Kamins, 1993) In this study, secondary data is collected from books and journals about customer satisfaction and hotline service quality
3.6 Survey of questionnaire
Due to the application of quantitative research method, primary data is expected collecting from well-structured survey of questionnaire This survey is designed with two parts The first part helps to collect demographic information such as gender, age, and education level of the respondents The second part helps to collect evaluation of customers towards current quality and performance of hotline service in Ministry of
Trang 21Health To help the customers’ evaluation, a Likert scale of 5 points and it ranges from
1 (strongly disagree) and 5 (strongly agree)

Trang 22Moreover, survey of questionnaire must be clear and candid to ensure that the respondents understand clearly about its contents To do that survey of questionnaire is put into pilot test whether a sample of 10 people who are working in customer service department of Ministry of Health is invited into this process The result shows that 10 respondents understand clearly about the survey of questionnaire’s contents
3.7 Sampling
Probability and non-probability are two common sampling method (Saunders et al., 2009) Sampling is important due to it helps the researchers to collect accurate data from their analyses and therefore obtaining research objectives and research questions (Saunders et al., 2009) In this study, probability sampling is selected with random sampling technique Random sampling is relevant due to minimal knowledge about total population size (Zikmund and Babin, 2007) Then, sample size is determined through a rule which is provided by Hair et al (1998) Under this rule, adequate sample size must be from 100 to 150 Therefore, a sample of 100 respondents will be chosen as target sample size in this study
In this study, the author would like to collect primary data from 100 respondents who are customers: patients and patients relatives particularly The author has come by her own to some of the biggest hospitals in Hanoi, Vietnam such as: Bach Mai Hospital, Viet Duc Hospital and Hong Ngoc Hospital to deliver questionnaires and wait there to collect them The survey was conducted in both public and private hospital to gain reliability
3.8 Data analysis techniques
Due to the application of quantitative research method, the study is developed further with several data analysis techniques, including descriptive statistics, reliability test, explanatory factor analysis or EFA, ANOVA, and multiple linear regression All these data analysis techniques are conducted and run through SPSS software which is being used widely in academic researches Descriptive statistics are developed with frequency analysis and mean value calculation Reliability analysis provides evidence of reliability level in the survey scale Explanatory factor analysis – EFA is utilised to check the validity of the constructs between variables and service quality’s factors ANOVA is conducted to verify the difference among respondents who have different
