The Use of Delayed Telephone Informed Consent for Observational Emergency Medicine Research Is Ethical and Effective
Open accessAbstract
Objectives: The objective was to describe the rate of successful consent using an altered (deferred telephone) consent process in emergency department (ED) patients. Methods: This study evaluated the consent process employed during a prospective, multicenter, observational study of outcomes in anticoagulated patients with blunt head trauma. The study was approved by the institutional review boards (IRB s) at all participating centers. Patients were not informed of the study during their enrollment at their index ED visit. Patient names, clinical findings, and contact information were collected at the time of initial ED visits. The patients or their legally designated surrogates were contacted by telephone at least 14 days after ED discharge, given all the elements of informed consent, and then consented for study participation. Study results are presented with simple descriptive statistics. Results: A total of 506 patients with a mean (±SD) age of 75.8 (±12.2) years including 274 female subjects (54.2%; 95% confidence interval [CI] = 49.7% to 58.6%) were enrolled into the study. Patients or their surrogates were successfully contacted by telephone in 501 of 506 cases (99.0%; 95% CI = 97.7% to 99.7%). Consent was obtained in 500 of 501 cases at time of telephone follow‐up (99.8%; 95% CI = 98.9% to 100.0%). Surrogates provided consent in 199 cases (39.7%; 95% CI = 35.4% to 44.2%). Median time from ED visit to phone contact was 21 days (interquartile range [IQR] = 17 to 27 days). The median number of phone attempts for successful contact was 1 (IQR = 1 to 2 attempts). Conclusions: The authors achieved a very high rate of successful telephone follow‐up in this predominantly older ED population. Obtaining consent to participate in a research study using a deferred telephone contact process was effective and well received by both subjects and surrogates. IRB s should consider deferred telephone consent for minimal‐risk studies requiring telephone follow‐up, as opposed to a consent process requiring written documentation at the time of initial ED visit.

In the citing paper
“Another concern pertains to the substantially disproportionate funding favouring commercial research evaluating the efficacy of highcost, patent protected drugs or devices over the undoubtedly necessary, non-commercial, academic resuscitation research on patent-unprotected, low-cost, widely used drugs of potentially uncertain efficacy, such as adrenaline (epinephrine), or antiarrhythmics. 63,318,”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
