Erratum To: Virtual house calls for Parkinson disease (Connect.Parkinson): study protocol for a randomized, controlled trial

After the publication of this article [1], it was discovered that eleven of the trials listed in the original article's Table 1 [1], had been erroneously identified as taking place in the home [2–12]. These studies actually evaluated physician videoconferencing visits with patients located in clinics. To ensure accuracy, we repeated the literature search in September of 2015, using the same search terms reported in the article and filtered for a publication date prior to July 1, 2014 (the original work was performed in June 2014.) We searched PubMed using the terms ‘telemedicine AND home AND randomized’ (378 results), ‘randomized AND video AND home’ (259 results), ‘videoconferencing AND randomized’ (178 results), and ‘virtual AND visits AND home’ (33 results), and reviewed the 141 studies identified in the review by Dr. Wootton mentioned in the article [13]. Of the 848 search results and 141 studies identified by Dr. Wootton, a total of six randomized controlled trials involving physician video calls directly to a patient in the home were identified (four from the original review [14–17] and two additional studies [18, 19] identified through the new search). The eleven misidentified articles have been removed from the Corrected Table 1, and included for clarity as Erratum Table 2. The final paper listed in Erratum Table 2, Bishop JE et al. [3], has also been corrected here: our article reported 19 subjects, but the abstract indicates that 17 completed the study. We sincerely apologize for the oversight and any inconvenience these errors might have caused.
