It is unclear whether previously developed frameworks for effective consultation apply to requests initiated by alphanumeric text page. We assessed a random sample of 210 text paged consult requests for communication of previously described 'essential elements' for effective consultation: reason for consult, level of urgency and requester contact information. Overall page quality was evaluated on a 5-point Likert scale. Over 90% of text paged consult requests included contact information and reason for consult; 14% indicated level of urgency. In ordinal logistic regression, reason for consult was most strongly associated with quality (OR 22.4; 95% CI 8.1 to 61.7), followed by callback number (OR 6.2; 95% CI 0.8 to 49.5), caller's name (OR 5.0; 95% CI 1.9 to 13.1) and level of urgency (OR 3.3; 95% CI 1.6 to 6.7). Results suggest that text paged consult requests often include most informational elements, and that urgency, often missing, may not be as 'essential' for text pages as it was once thought to be.

In the current study, we explored exaggerated physiological startle responses in posttraumatic stress disorder (PTSD) and examined startle reactivity as a biomarker of PTSD in a large veteran sample. We assessed heart rate (HR), skin conductance (SC), and electromyographic (EMG) startle responses to acoustic stimuli under low-, ambiguous-, and high-threat conditions in Gulf War veterans with current (n = 48), past (n = 42), and no history of PTSD (control group; n = 152). We evaluated PTSD status using the Clinician-Administered PTSD Scale and trauma exposure using the Trauma History Questionnaire. Participants with current PTSD had higher HR, ds = 0.28-0.53; SC, d = 0.37; and startle responses than those with past or no history of PTSD. The HR startle response under ambiguous threat best differentiated current PTSD; however, sensitivity and specificity analyses revealed it to be an imprecise indicator of PTSD status, ROC AUC = .66. Participants with high levels of trauma exposure only showed elevated HR and SC startle reactivity if they had current PTSD. Results indicate that startle is particularly elevated in PTSD when safety signals are available but a possibility of danger remains and when trauma exposure is high. However, startle reactivity alone is unlikely to be a sufficient biomarker of PTSD.
