Purpose

Most health-care marketing activities aim to provide the best service quality, ultimately achieving high patient satisfaction. Clinical laboratories are an important part of health-care delivery, and 70% of treatment decisions are based on accurate laboratory results. Multiple service quality models have been developed in the hospital industry; however, limited research has been conducted on the dimensions of laboratory services. The purpose of this study is to develop a laboratory service quality instrument (LABQUAL) via the modified Delphi technique.

Design/methodology/approach

Based on a literature review, quality standards defined by accreditation body questionnaires were developed. An expert team of 15 industry experts and academicians participated in two rounds of the modified Delphi technique to provide opinions on the service quality framework. The feedback was given on a nine-point Likert scale via an online survey.

Findings

Mutual consensus was established on the basis of the interquartile range and the proportion of respondents who rated the outcome as critically important. Seven constructs and 35 items were finalized as part of LABQUAL to measure service quality.

Originality/value

LABQUAL fills a significant research gap by offering a tailored service quality assessment tool specifically for clinical laboratories. This framework enables health-care providers to evaluate and enhance service quality systematically, ultimately contributing to improved patient outcomes and decision-making accuracy.
