Association between health literacy and patient experience of primary care attributes: A cross-sectional study in Japan

Abstract

Primary care is regarded as a setting that potentially mitigate patient health literacy (HL) related inequalities. However, there is a lack of evidence about influence of patient HL on the patients' perception of quality of primary care. We aimed to examine the association between HL and patient experience of primary care attributes. We conducted a cross-sectional survey, and sent questionnaires to adult residents who were randomly selected from a basic resident register in Yugawara Town, Kanagawa, Japan. We assessed HL using a 14-item Health Literacy Scale (HLS-14) and patient experience of primary care attributes using a Japanese version of Primary Care Assessment Tool (JPCAT), which comprises six domains: first contact, longitudinality, coordination, comprehensiveness (services available), comprehensiveness (services provided), and community orientation. We used a multivariable linear regression analyses to adjust individual covariates. Data were analyzed for 381 residents who had a usual source of care. After adjustment for patients' sociodemographic and health characteristics, patient HL was positively associated with the JPCAT total score (B = 4.49, 95% confidence interval: 0.27 to 8.65 for HLS-14 total score highest quartile, compared with the lowest quartile). Among primary care attributes, HL had significant associations with longitudinality and comprehensiveness (service provided). We found that HL was positively associated with patient experience of primary care attributes in Japanese people. Our findings indicated that greater efforts might be needed to improve patient-centered and tailored primary care to those with low HL.
