Mass screening for fever in children: a comparison of 3 infrared thermal detection systems.

OBJECTIVES: Infrared thermal detection systems (ITDSs) have been used with limited success outside the United States to screen for fever during recent outbreaks of novel infectious diseases. Although ITDSs are fairly accurate in detecting fever in adults, there is little information about their utility in children. METHODS: In a pediatric emergency department, we compared temperatures of children (<18 years old) measured using 3 ITDSs (OptoTherm Thermoscreen, FLIR ThermoVision 360, and Thermofocus 0800H3) to standard, age-appropriate temperature measurements (confirmed fever defined as ≥38.0°C [oral or rectal], ≥37.0°C [axillary]). Measured temperatures were compared with parental reports of fever using descriptive, multivariate, and receiver operating characteristic analyses. RESULTS: Of 855 patients, 400 (46.8%) had parent-reported fever, and 306 (35.8%) had confirmed fever. At optimal fever thresholds, OptoTherm and FLIR had sensitivity (83.0% and 83.7%, respectively) approximately equal to parental report (83.9%) and greater than Thermofocus (76.8%), and specificity (86.3% and 85.7%) greater than parental report (70.8%) and Thermofocus (79.4%). Correlation coefficients between traditional thermometry and ITDSs were 0.78 (OptoTherm), 0.75 (FLIR), and 0.66 (Thermofocus). CONCLUSIONS: Compared with traditional thermometry, FLIR and OptoTherm were reasonably accurate in detecting fever in children and better predictors of fever than parental report. These findings suggest that ITDSs could be a useful noninvasive screening tool for fever in the pediatric age group.

Travel Health Alert Notices and Haiti cholera outbreak, Florida, USA, 2011.

To enhance the timeliness of medical evaluation for cholera-like illness during the 2011 cholera outbreak in Hispaniola, printed Travel Health Alert Notices (T-HANs) were distributed to travelers from Haiti to the United States. Evaluation of the T-HANs' influence on travelers' health care­seeking behavior suggested T-HANs might positively influence health care­seeking behavior.

Impact of port of entry referrals on initiation of follow-up evaluations for immigrants with suspected tuberculosis: Illinois.

US-bound immigrants with suspected non-infectious TB are encouraged to be medically re-evaluated after arrival in the United States. We evaluated the Centers for Disease Control and Prevention's immigrant referral process, designed to facilitate timely post-arrival evaluations. Over 1,200 immigrants with suspected TB arriving during October 1, 2008-September 30, 2010 were identified. In 2011, differences in days to evaluation initiation were assessed by referral type using survival analysis and Cox proportional hazard models. Among those receiving any referral, median time to post-arrival evaluation was significantly lower compared with immigrants receiving no referral (16 vs. 69 days, respectively; p < 0.0001). After adjusting for the covariates, immigrants receiving any referral initiated follow-up at 4 times the rate (adjusted hazard ratio = 4.0; p < 0.0001) of those receiving no referral. Implementing a referral system at US ports of entry will improve timeliness and increase the proportion of immigrants initiating domestic evaluation.

Factors associated with inpatient mortality in a field hospital following the Haiti earthquake, January-May 2010.

OBJECTIVE: To describe factors associated with inpatient mortality in a field hospital established following the 2010 Haiti earthquake. DESIGN: Data were abstracted from medical records of patients admitted to the University of Miami Global Institute/Project Medishare hospital. Decedents were compared to survivors in terms of age, sex, length of stay, admission ward, diagnosis, and where relevant, injury mechanism and surgical procedure. Three multivariate logistic regression models were constructed to determine predictors of death among all patients, injured patients, and noninjured patients. RESULTS: During the study period, 1,339 patients were admitted to the hospital with 100 inpatient deaths (7.5 percent). The highest proportion of deaths occurred among patients aged < or = 15 years. Among all patients, adult intensive care unit (ICU) admission (adjusted odds ratio [AOR] = 7.6 and 95% confidence interval [CI] = 3.4-16.8), neonatal ICU/pediatric ICU (NICU/PICU) admission (AOR = 7.8 and 95% CI = 2.7-22.9), and cardiac/respiratory diagnoses (AOR = 8.5 and 95% CI = 4.9-14.8) were significantly associated with death. Among injured patients, adult ICU admission (AOR = 7.4 and 95% CI = 1.7-33.3) and penetrating injury (AOR = 3.3 and 95% CI = 1.004-11.1) were significantly associated with death. Among noninjured patients, adult ICU admission (AOR = 6.6 and 95% CI = 2.7-16.4), NICU/PICU admission (AOR = 8.2 and 95% CI = 2.1-31.8), and cardiac/ respiratory diagnoses (AOR = 6.5 and 95% CI = 3.6-12.0) were significantly associated with death. CONCLUSIONS: Following earthquakes in resource-limited settings, survivors may require care in field hospitals for injuries or exacerbation of chronic medical conditions. Planning for sustained post-earthquake response should address these needs and include pediatric-specific preparation and long-term critical care requirements.
