Cross-functional CRM systems in pharmacy: Enhancing service quality, patient loyalty, and engagement

Abstract

Aim/Background: Pharmacies increasingly leverage cross-functional Customer Relationship Management (CRM) systems to improve not only business outcomes but also pharmacotherapy adherence and patient engagement. This study examines how adopting an integrated CRM in retail pharmacy influences service quality and patient loyalty, and discusses implications for medication adherence and pharmacovigilance. Materials and Methods: A cross-sectional survey was conducted in 10 community pharmacies, capturing responses from pharmacy patients (n = 250) and managers (n = 40). Patients rated perceived service quality and loyalty, while managers reported on CRM implementation (integration of communication channels, centralized patient databases, and staff training). The survey instruments included adapted service quality (SERVQUAL) and loyalty scales. A power analysis confirmed the sample was sufficient for detecting medium effects (80% power). Data were analyzed using correlations and regression models with service quality as a mediator. Ethical approval was obtained, and all participants provided informed consent. Bootstrapping techniques are recommended for future studies to validate indirect effects. Prior to regression analysis, key statistical assumptions were tested. Normality of residuals was assessed using the Shapiro–Wilk test and visual inspection of Q–Q plots, which indicated no substantial deviations from normality. Linearity and homoscedasticity were evaluated through scatterplots of standardized residuals, confirming linear relationships between variables and constant variance. Multicollinearity was assessed using Variance Inflation Factors (VIF), all of which were below 2.0, indicating no multicollinearity concerns. Results: Pharmacies with higher cross-functional CRM adoption demonstrated significantly better service quality perceptions and stronger patient loyalty. CRM integration was associated with higher overall service quality scores (mean 4.21 vs. 3.62 in low-CRM pharmacies, p<0.001) and greater emotional attachment and repeat patronage. Multiple regression showed that CRM integration positively predicted service quality (β=0.54, 95% CI [0.40–0.68], p<0.001). In turn, service quality strongly predicted emotional loyalty (β=0.62, 95% CI [0.50–0.74]) and partially mediated the effect of CRM on loyalty. Even after accounting for service quality, CRM had a direct positive effect on emotional loyalty (β≈0.18, p<0.05). These findings suggest that an integrated CRM enables more reliable, responsive, and personalized pharmacy services, fostering patient trust and engagement. Conclusion: Cross-functional CRM systems in pharmacies substantially improve perceived service quality, which elevates patient loyalty and likely supports better medication adherence. By centralizing patient data and communications, CRM tools allow pharmacists to deliver tailored interventions (e.g., refill reminders, follow-up on therapy), enhancing patient engagement in care. CRM implementation is associated with improved service quality and customer loyalty. These factors may indirectly influence medication adherence through enhanced patient engagement and communication, although adherence and safety outcomes were not directly measured in this study. The study underscores CRM as not just a marketing tool but a clinical support system that can strengthen pharmacotherapy outcomes. Future research should use longitudinal and experimental designs to confirm causal effects of CRM-driven patient engagement on adherence and health outcomes.
