Standardized Vaccine-Hesitant Patients in the Assessment of the Effectiveness of Vaccine Communication Training.

OBJECTIVES: To determine if training residents in a structured communication method elicits specific behaviors in a laboratory model of interaction with vaccine-hesitant parents. STUDY DESIGN: Standardized patients portraying vaccine-hesitant parents were used to assess the effectiveness of training in the Announce, Inquire, Mirror, Secure (AIMS) Method for Healthy Conversations. Blinded pediatric residents were pseudorandomized to receive AIMS or control training and underwent pre- and post-training encounters with blinded standardized patients. Encounters were assessed by blinded raters using a novel tool. Participant confidence and standardized patient evaluations of the participants' general communication skills were assessed. RESULTS: Ratings were available for 27 AIMS and 26 control participants. Statistically significant increases in post-training scores (maximum = 30) were detected in AIMS, but not in control, participants (median, 21.3 [IQR, 19.8-24.8] vs 18.8 [IQR, 16.9-20.9]; P < .001). Elements (maximum score = 6) with significant increases were Inquire (0.67 [IQR, 0-1.76] vs -0.33 [IQR, -0.67 to 0.33]; P < .001); Mirror (1.33 [IQR, 0 to 2] vs -0.33 [IQR, -0.92 to 0]; P < .001) and Secure (0.33 [IQR, 0 to 1.67] vs -0.17 [IQR, -0.67 to 0.33]; P = .017). Self-confidence increased equally in both groups. Standardized patients did not detect a difference in communication skills after training and between groups. Internal consistency and inter-rater reliability of the assessment tool were modest. CONCLUSIONS: Standardized patients proved useful in studying the effectiveness of structured communication training, but may have been limited in their ability to perceive a difference between groups owing to the predetermined encounter outcome of vaccine refusal. AIMS training should be studied in real-world scenarios to determine if it impacts vaccine acceptance.

Clinical and laboratory features, hospital course, and outcome of Rocky Mountain spotted fever in children.

OBJECTIVES: To describe the clinical characteristics and course of children with laboratory-diagnosed Rocky Mountain spotted fever (RMSF) and to identify clinical findings independently associated with adverse outcomes of death or discharge with neurologic deficits. STUDY DESIGN: Retrospective chart review of 92 patients at six institutions in the southeastern and southcentral United States from 1990 to 2002. Statistical analyses used descriptive statistics and multiple logistic regression. RESULTS: Children with RMSF presented to study institutions after a median of 6 days of symptoms, which most commonly included fever (98%), rash (97%), nausea and/or vomiting (73%), and headache (61%); no other symptom or sign was present in >50% of children. Only 49% reported antecedent tick bites. Platelet counts were <150,000/mm3 in 59% of children, and serum sodium concentrations were <135 mEq/dL in 52%. Although 86% sought medical care before admission, only 4 patients received anti-rickettsial therapy during this time. Three patients died, and 13 survivors had neurologic deficits at discharge. Coma and need for inotropic support and intravenous fluid boluses were independently associated with adverse outcomes. CONCLUSIONS: Children with RMSF generally present with fever and rash. Delays in diagnosis and initiation of appropriate therapy are unacceptably common. Prognosis is guarded in those with hemodynamic instability or neurologic compromise at initiation of therapy.
