The current study aims at developing a conceptual framework containing original dimensions of SERVQUAL and adding two modified dimensions: patient safety and medical professionalism in healthcare service quality (HSQ) model.

An extensive review of HSQ literature pertaining to its dimensions and models with respect to content analysis and bibliometric studies of service quality in healthcare and SERVQUAL in healthcare were performed on 47 relevant studies, 4,689 and 529 documents after applying inclusion and exclusion criteria. Google Scholar and Scopus were the primary sources to find the relevant documents.

The content analysis was conducted to group HSQ dimensions into seven themes. Co-occurrence analysis of author keywords was performed in VOSviewer to find the links between service quality, SERVQUAL and proposed dimensions. Organization and analysis of different HSQ models and dimensions emerged from the literature result in a comprehensive conceptual framework comprising modified dimensions of healthcare service quality – medical professionalism and patient safety.

SERVQUAL is a widely accepted, tested and validated model in perceiving HSQ from the lenses of patients. But it does not cover the complex nature of healthcare service, thus requiring modification and the addition of new contextual dimensions. Therefore, a comprehensive conceptual framework is developed to validate and test quantitatively.

The purpose of this study is to explore the literature of healthcare service quality for identifying and analyzing the healthcare service quality models and dimensions and to present future research insights pertaining to the applications of these models and dimensions.

A literature review of healthcare service quality has been performed on 59 relevant studies after applying inclusion and exclusion criteria. Google Scholar and Scopus are the primary sources to find the relevant documents. Search was limited to keywords of “service quality,” “healthcare,” “models” and “dimensions.”

The results revealed that different models and dimensions have been evolved and developed after SERVQUAL in healthcare service quality literature. There is still a need to develop new models, add new contextual dimensions and items in existing models on different aspects of healthcare services. There is also a need to incorporate the perspective of service providers as respondents. Moreover, healthcare service quality models can be devolved or narrowed down at department and individual levels.

This study presents valuable research insights for the researchers and practitioners in ways that healthcare service quality models and dimensions can be developed, modified and tested further in different research contexts and settings. Besides, the literature on healthcare services can be enhanced and enriched.
