Despite the growing research interest in the digitization of healthcare, current understanding of barriers of using healthcare IT are mostly centered round providers. There is a lack of understanding of how to get patients involved in managing their own health information digitally by using standalone Personal Health Record Systems (PHR). To fill the research gap, this study uses the literature on information privacy to theorize and empirically test how individuals’ willingness to use standalone PHR is driven by a privacy calculus buttressed by the level of perceived control over their own health information. The perceived benefits of PHR and perceived control are suggested to be the major factors overriding the effect of potential privacy risks of PHR.
