Abstract
The aim of this study is to identify the main moderators in the relationship between antecedents/predictors (doctors, privacy, accessibility, and availability, perceived waiting time to be called back by the doctor after the examinations and/or tests) and the perceived quality of healthcare (PQHC) in the emergency department (ED). Patients admitted to the ED of a public hospital in Lisbon, Portugal, between January and December 2016 were included in this study, with a representative sample size of 382 patients. A 5% margin of error and a 95% confidence interval were used, and all data were collected between May and November 2017. We used a stepwise multiple linear regression analysis to test the moderation models. We identified 3 main moderators with different moderating roles between the antecedents (predictors) and PQHC: level of life satisfaction, level of happiness, and frequency of ED experiences. Overall satisfaction with doctors is more likely to influence the PQHC among patients with lower levels of life satisfaction. Moreover, privacy and perceived waiting time to be called back by the doctor after an examination and/or test are more likely to influence the PQHC among patients with lower levels of life satisfaction and happiness. Finally, accessibility and availability are more likely to influence the PQHC among patients with more frequent ED experiences. Thus, knowing the moderating effects of psychological factors and the frequency of ED experiences may help to better understand the relationship between PQHC and certain predictors.
