Home monitoring devices encourage people to actively participate in their health care management. In addition, access to more data may help to make better decisions, which may ultimately lead to better health outcomes. The primary focus of this article will be on blood glucose, blood pressure, prothrombin time, and peak flow meters. The empirical evidence on the accuracy and usefulness of these home monitoring devices is discussed. Based on the evidence from the literature, erroneous reporting of the readings by the patients is a major concern. Therefore, primary practitioners are encouraged to consult with patients’ log books and their meters (if memory feature is available), instead of relying solely on self-reported values. Patients also need to be educated and trained adequately about the proper measurement technique and relevance and interpretation of the readings. Continuing education is necessary regarding the behavioral and therapeutic changes patients should carry out in accordance with performing regular home monitoring.
