Abstract

Senior healthcare IT leaders concerned about cybersecurity in electronic health records (EHR) continue to face fundamental challenges when efficiently managing EHR cybersecurity infrastructures to fulfill business objectives. Grounded in the updated DeLone and McLean information system success model, the purpose of this quantitative multiple linear regression study was to examine relationships between information quality, system quality, service quality, and user satisfaction related to cybersecurity and cloud computing infrastructures for EHR. The participants were 161 senior healthcare IT leaders in North and South Carolina who completed a survey that used an instrument scale based on ISS. The results of the multiple linear regression were significant, F(3,157) = 267.89, p = 0.001, R2 = 0.84. In the final model, three predictors were significant, information quality (t = 2.74, p = 0.007, β = 0.25), system quality (t = 4.77, p = 0.001, β = 0.31,), and service quality (t = 2.70, p = 0.008, β = 0.12,). A key recommendation is for senior healthcare IT leaders to assess cybersecurity for EHR to ensure patient expectations and user satisfaction. The implication for positive social change includes the potential for cybersecurity leaders to build a reliable cybersecurity solution that improves healthcare solutions for the public.
