Evaluation of healthcare service quality factors using grey relational analysis in a dialysis center

Abstract

Purpose The purpose of this paper is to investigate the relative influences of technical and functional quality levels of service quality and patient satisfaction. In this context, the healthcare service quality and the factors affecting customer satisfaction were evaluated using the grey relational analysis (GRA) method. Design/methodology/approach This is a survey-based study which involves 15 patients in a dialysis center, so the GRA is applied to clarify the uncertainty on service quality level with a limited number of patients without any statistical distribution. In order to reveal whether service quality and customer satisfaction are two different structures, a GRA model is built with ten different quality factors. Findings Results show that each quality factor has a different effect on the quality of service. Another important finding is that service quality and customer satisfaction are different structures for customers. Practical implications The results enable healthcare managers to understand the importance of patient care and the importance of service quality if they want to facilitate their use of their expectations in related factors. Originality/value The study is the first in terms of the application of GRA models in a private health institution operating in Turkey. Successful implementation of the GRA method allows a reasonable decision to be made with a limited number of data at hand. It is considered that the method can be used successfully in other health institutions in the Turkish Health System.

An Empirical Study on Online Learners’ Continuance Intentions in China

“…Sassere et al observed that service quality includes two parts, the service results and the method of providing services [45]. Roca et al held a view that service quality is intimately correlated with confirmation and, thereby, the perceived usefulness of online education [46].…”

Evaluation of Low-Carbon Sustainable Technologies in Agriculture Sector through Grey Ordinal Priority Approach

“…The key areas of Grey System Theory include grey relational analysis, grey generating space, grey forecasting, grey decision making, grey control, and grey mathematics. Grey System Theory has seen application in numerous fields, including agriculture (Tan et al, 2014), supplier selection (Mahmoudi et al, 2021a), economic growth analysis (Huang et al, 2020), health care management (Aydemir & Sahin, 2019;Javed and Liu., 2018), sustainable development (Ikram et al, 2021;Abid et al, 2021), environment (Hao et al, 2006), electromagnetic data processing (Jiang et al, 2017), traffic flow prediction (Xiao et al, 2020), energy and emissions (Chen et al, 2021;Zhu et al, 2019), project management (Sheikh et al, 2019;Javed & Liu, 2019), machine learning (Xie et al, 2021;Ma, 2019), among others. It can be seen that the application of Grey System Theory is widespread and multi-disciplinary.…”

A Comprehensive Solution Approach for CNC Machine Tool Selection Problem

“…An essential approach of the grey system theory (GST) used in the decision-making process and measuring the changes of similarities and differences between its factors over time is called Grey Relational Analysis (GRA) (Feng and Wang, 2000;Aydemir et al, 2013). This method is used in the elimination and analysis of ambiguous relationships between criteria and options, examination of integrated circuit marking process (Jiang et al, 2002), restoration planning of power distribution systems (Chen et al, 2005), recruitment decisions (Olson and Wu, 2006), damage assessment (He and Hwang, 2007), a causal decision-making model (Tseng, 2009), determination of critical path through a network (Zhongmin and Xizu, 2009), supplier selection (Yang and Chen, 2006;Özdemir and Deste, 2009;Zavadskas et al, 2010;Hashemi et al, 2015;Cakir and Akel, 2017), stock market forecasts and portfolio selection (Huang and Jane, 2009), optimization of turning parameters (Yilmaz and Gungor, 2010;Ramesh et al, 2016;Prakash et al, 2020;Lakshmanan et al, 2021), evaluation of e-commerce system security (Liu, 2011), ergonomics (Akay, 2011), evaluation of the performance of enterprises (Tayyar et al, 2014;Aydemir and Sahin, 2019), risk and quality analysis (Baynal et al, 2018;Yazdani et al, 2019), product analysis (Chan and Tong, 2007;Sahin and Aydemir, 2019), and social networks (Weng et al, 2021).…”
