Background:
With the impressive advantages of patient-pharmacist communication being advocated and poor pharmacist-patient communication in different settings, it is of great significance and urgency to explore the mechanism of the pharmacist-patient communicative relationship. The King's theory of goal attainment is proposed as one of the most promising models to be applied, because it takes into consideration both improving the patient-pharmacist relationship and attaining patients' health outcomes.
Objectives:
This study aimed to validate the King's transaction process and build the linkage between the transaction process and patient satisfaction in a pharmaceutical context.
Methods:
A cross-sectional study was conducted in four tertiary hospitals in two provincial cities (Wuhan and Shanghai) in central and east China in July 2017. Patients over 18 were investigated in the pharmacies of the hospitals. The instrument for the transaction process was revised and tested. Path analysis was conducted for the King's transaction process and its relationship with patient satisfaction.
Results:
Five hundred eighty-nine participants were investigated for main study. Prior to the addition of covariates, the hypothesised model of the King's transaction process was validated, in which all paths of the transaction process were statistically significant (p < 0.001). The transaction process had direct effects on patient satisfaction (p < 0.001). After controlling the effects of covariates, the Multiple Indicators, Multiple Causes (MIMIC) model showed good fit to data (Tucker-Lewis index [TLI] = 0.99, comparative fit index [CFI] = 0.99, root mean square error of approximation [RMSEA] = 0.05, weighted root mean square residual [WRMR] = 1.00). The MIMIC model showed that chronic disease and site were predictors for both identifying problems and patient satisfaction (p < 0.05).
Conclusions:
Based on the well-fitting path analytic model, the transaction process was established as one valid theoretical framework of healthcare provider-patient communication in a pharmaceutical context.
