Purpose: The purpose of this paper is to identify the antecedents and outcomes of internal service quality (ISQ) in a health-care environment. The relationships among the heterogeneous health-care environment, coordinated care, perceived organisational support (POS), ISQ, internal customer satisfaction and patient-centred care were explored. Design/methodology/approach: Based on a review of the literature, a structural model was developed. A 37-item questionnaire was circulated among service providers in the health-care system, including doctors, nurses and system staff, all over India. The random sampling method was adopted to collect data. A total of 238 valid responses were received. The data were analysed using structural equation modelling. Findings: The results show that the heterogeneous environment, coordinated care and POS act as antecedents of ISQ, which drives internal customer satisfaction and patient centricity in health care. Research limitations/implications: The paper contributes to the health-care literature by identifying the antecedents and consequences of ISQ and developing a structural relationship among ISQ, the heterogeneous health-care environment, coordinated care, POS, internal customer satisfaction and patient-centred care. Practical implications: Hospital administrators may use various constructs of POS, ISQ and coordinated care to measure process and employee performance, which may aid the design of appropriate processes and improve employee selection. The constructs of patient centricity and internal customer satisfaction may be used as benchmarking tools to facilitate the formulation of immediate corrective actions and policies for future courses of action. Social implications: This paper highlights how patient centricity may be achieved by focussing on ISQ, coordinated care processes and a facilitative internal environment. This understanding may aid the design of processes that in turn deliver health as a social good in an effective manner. Originality/value: This paper extends past research on ISQ by showing that ISQ affects internal customer satisfaction and, in turn, the quality of service delivery in the system. In the health-care context, heterogeneity in patient needs, coordinated care and organisational support play crucial roles in determining ISQ, which in turn influences the level of patient-centred care.
