Service quality as a predictor of patient retention and word-of-mouth referral in secondary healthcare: Evidence from the Niger delta region, Nigeria

Abstract

This study investigated service quality as a predictor of patient retention and word-of-mouth (WOM) referral in secondary healthcare facilities within the Niger Delta region of Nigeria. Driven by increasing competition and shifting patient expectations, the research examined how five core dimensions of service quality tangibles, reliability, responsiveness, assurance, and empathy influence healthcare consumers' long-term loyalty and structural recommendations. A cross-sectional survey research design was adopted. Data were collected from 384 discharged patients across selected secondary health structures in Cross River, Delta, and Rivers States using a structured, structurally validated questionnaire. Structural Equation Modeling (SEM) and multiple regression techniques were used to analyze the data. The empirical findings revealed that service quality significantly and positively predicted both patient retention and word-of-mouth referral. Individually, empathy, responsiveness, and assurance exerted the strongest predictive influence on retention, while reliability and tangibles significantly drove positive word-of-mouth communications. The study concluded that clinical efficacy alone is insufficient to guarantee institutional survival in modern healthcare ecosystems; structural and interpersonal service delivery frameworks form the bedrock of sustainable patient relationship management. Based on these findings, it is recommended that hospital management boards in the Niger Delta prioritize continuous customer-care training for frontline staff, optimize internal administrative processes to reduce waiting times, and invest in basic physical infrastructure to improve the tangible healthcare environment.
