Despite the recent national analysis concerning the value of interoperability, which suggested that fully standardized interoperability could save the nation $77.8 billion annually, the lack of compatibility between healthcare systems is still a national problem and a national priority. Studies indicate implementing approaches to ensure that Electronic Health Records (EHRs) can interoperate, is a high priority. Despite the urgencies there is still a lack of qualitative and quantitative evidence

... illustrating the use of the four key EHR interoperability domains related to Primary Care Practitioners'(PCPs) performance on quality measures in relation to the care adolescents between the ages of 12-19 years old receive over time. In order to validate and provide answers to the research questions and hypotheses, the study established a baseline econometric model constructed as a multivariable linear regression equation. Performance to quality care within PCPs when providing quality access and availability of care to adolescents ages 12-19 years is the dependent variable while the four core EHR interoperability domains –find, send, receive, and integrate patient healthcare information are the predictors (independent variables) for this study. The results on both econometric models constructed for this study shows that none of the variable coefficients as regards to the dependent variable is significant at α = 0.05% and 0.01%. However, at both levels of α, all four EHR interoperability domains—electronically send, find, receive, and integrate patient clinical information (independent variables) show a positive relationship with the dependent variable (performance of quality measures). This means that as the usage of these four EHR interoperability domains increases (Independent variables), the net benefit of the access and availability to care for adolescents between 12-19 years old in the United States increases (Dependent variable), which expresses a positive relationship. Based on the magnitude of R values, the "Send p [...]
