A PICU patient safety checklist: rate of utilization and impact on patient care.

OBJECTIVE: In healthcare, checklists help to ensure patients receive evidence-based, safe care. Since 2007, we have used a bedside checklist in our PICU to facilitate daily discussion of care-related questions at each bedside. The primary objective of this study was to assess compliance with checklist use and to assess how often individual checklist elements affected patient management. A secondary objective was to determine whether patient and unit factors (severity of illness, unit census, weekday vs. weekend, admitting diagnosis group) influenced checklist use. DESIGN: This was a prospective observational study. A research assistant attended daily bedside rounds to collect data at each eligible patient encounter. SETTING: The study was conducted in the Children's Hospital of Eastern Ontario (CHEO) PICU, a 12-bed cardiac and medical-surgical unit. PARTICIPANTS: Included all patients admitted to the PICU prior to 6 am and who were not being discharged that day. INTERVENTION: A bedside rounds checklist. MAIN OUTCOME MEASURES: Included compliance and whether the checklist affected the patient's management plan. RESULTS: A total of 148 encounters were collected on 28 days between September 2013 and February 2014. Compliance with the checklist was 89.2% (132/148; 95% CI 83.2-93.2%) and was not influenced by admitting diagnosis group, patient census, severity of patient's conditions or weekday/weekend status. The checklist affected the patient management plan 52.6% of the time (69/132; 95% CI 44.2-61%). CONCLUSIONS: Our study found high rates of compliance with an established checklist that has been in use in the PICU since 2007. Checklist use frequently resulted in a change in the patient management plan.

Prenatal fluoride exposure and attention deficit hyperactivity disorder (ADHD) symptoms in children at 6-12 years of age in Mexico City.

BACKGROUND: Epidemiologic and animal-based studies have raised concern over the potential impact of fluoride exposure on neurobehavioral development as manifested by lower IQ and deficits in attention. To date, no prospective epidemiologic studies have examined the effects of prenatal fluoride exposure on behavioral outcomes using fluoride biomarkers and sensitive measures of attention. OBJECTIVE: We aimed to examine the association between prenatal fluoride exposure and symptoms associated with attention-deficit/hyperactivity disorder (ADHD). METHOD: 213 Mexican mother-children pairs of the Early Life Exposures to Environmental Toxicants (ELEMENT) birth cohort study had available maternal urinary samples during pregnancy and child assessments of ADHD-like behaviors at age 6-12. We measured urinary fluoride levels adjusted for creatinine (MUFcr) in spot urine samples collected during pregnancy. The Conners' Rating Scales-Revised (CRS-R) was completed by mothers, and the Conners' Continuous Performance Test (CPT-II) was administered to the children. RESULTS: Mean MUFcr was 0.85 mg/L (SD = 0.33) and the Interquartile Range (IQR) was 0.46 mg/L. In multivariable adjusted models using gamma regression, a 0.5 mg/L higher MUFcr (approximately one IQR higher) corresponded with significantly higher scores on the CRS-R for DSM-IV Inattention (2.84 points, 95% CI: 0.84, 4.84) and DSM-IV ADHD Total Index (2.38 points, 95% CI: 0.42, 4.34), as well as the following symptom scales: Cognitive Problems and Inattention (2.54 points, 95% CI: 0.44, 4.63) and ADHD Index (2.47 points; 95% CI: 0.43, 4.50). The shape of the associations suggested a possible celling effect of the exposure. No significant associations were found with outcomes on the CPT-II or on symptom scales assessing hyperactivity. CONCLUSION: Higher levels of fluoride exposure during pregnancy were associated with global measures of ADHD and more symptoms of inattention as measured by the CRS-R in the offspring.
