Impact of C-reactive protein test results on evidence-based decision-making in cases of bacterial infection

BACKGROUND: C-reactive protein (CRP) is widely used to detect bacterial infection in children. We investigated the impact of CRP test results on decision-making and summarized the evidence base (EB) of CRP testing. METHODS: We collected information from the hospital records of 91 neonates with suspected sepsis and of 152 febrile children with suspected infection on the number of ordered CRP tests, the number of EB-CRP tests, and the impact of the test results on decision-making. CRP diagnostic accuracy studies focusing on pediatric infections were reviewed critically. The main outcomes were the proportion of CRP tests that were EB and the proportion of tests that affected decision-making. A secondary outcome was the overall one-year expenditure on CRP testing. RESULTS: The current EB for CRP testing in pediatric infections is weak and suggests that CRP is of low diagnostic value. Approximately 54.8% of tests performed for suspected neonatal sepsis and 28% of tests performed for other infections were EB; however, the results of only 12.9% of neonatal sepsis tests and of 29.9% of tests on children with other infections informed decision-making. The one-year overall cost for CRP testing and related health care was $26,715.9. CONCLUSIONS: The routine ordering of CRP for children with infections is based on weak evidence. The impact of the CRP test results on decision-making is rather small, and CRP ordering may contribute to unnecessary health care expenditures. Better quality research is needed to definitively determine the diagnostic accuracy of CRP levels in children with infections

Axillary and rectal thermometry in the newborn: do they agree?

BACKGROUND: Accurate measurement of body temperature is critical for the assessment of a newborn’s general well-being. In nursery settings, the gold standard rectal thermometry has been replaced by the axillary method. However, evidence pertaining to the agreement between axillary and rectal thermometry in the newborn is controversial. In this cross-sectional study, the agreement between axillary and rectal temperature in newborns, as well as the effects of neonatal, maternal and environmental factors on this agreement were investigated. METHODS: The mean difference between axillary and rectal temperatures was compared in stable term and preterm newborns using paired t-test for the means of differences, Pearson correlation coefficient (r), and the Bland-Altman plot. Stepwise multivariate regression assessed predictors of this difference in the overall group and by gestational age categories. RESULTS: The study included 118 newborns with gestational ages ranging from 29 to 41 weeks, median birth weight of 2980 grams (IQR: 2321.3-3363.8). Axillary and rectal temperatures correlated significantly (r = 0.5, p = 0.000) and had similar overall means but differed in 34–36 weeks gestation newborns (p = 0.01). Correlation between both methods increased with advancing gestational age being highest in term newborns (r = 0.6, p = 0.000). Bland-Altman plots revealed good agreement in gestational ages above 29 weeks. The difference between measurements increased with Cesarean delivery (ß = 0.2; 95% CI: 0.02, 0.38), but decreased with advancing chronological age (ß = -0.01; 95% CI: -0.02,-0.01), and with gestational age (ß = -0.05; 95% CI: -0.08,-0.01). CONCLUSION: In clinically stable term and preterm infants, axillary thermometry is as reliable as rectal measurement. Predictors of agreement between the two methods include gestational age, chronological age and mode of delivery. Further studies are needed to confirm this agreement in sick newborns and in extremely premature infants

Blood Lead Concentrations in 1–3 Year Old Lebanese Children: A Cross-sectional study

BACKGROUND: Childhood lead poisoning has not made the list of national public health priorities in Lebanon. This study aims at identifying the prevalence and risk factors for elevated blood lead concentrations (B-Pb ≥ 100 μg/L) among 1–3 year old children. It also examines the need for universal blood lead screening. METHODS: This is a cross-sectional study of 281 well children, presenting to the pediatric ambulatory services at the American University of Beirut Medical Center in 1997–98. Blood was drawn on participating children for lead analysis and a structured questionnaire was introduced to mothers asking about social, demographic, and residence characteristics, as well as potential risk factors for lead exposure. Children with B-Pb ≥ 100 μg/L were compared to those with B-Pb < 100 μg/L. RESULTS: Mean B-Pb was 66.0 μg/L (median 60.0; range 10–160; standard deviation 26.3) with 39 (14%) children with B-Pb ≥ 100 μg/L. Logistic regression analysis showed that elevated B-Pb was associated with paternal manual jobs (odds ratio [OR]: 4.74), residence being located in high traffic areas (OR: 4.59), summer season (OR: 4.39), using hot tap water for cooking (OR: 3.96), exposure to kohl (OR: 2.40), and living in older buildings (OR: 2.01). CONCLUSION: Lead screening should be offered to high-risk children. With the recent ban of leaded gasoline in Lebanon, emphasis should shift to other sources of exposure in children

Equal antipyretic effectiveness of oral and rectal acetaminophen: a randomized controlled trial [ISRCTN11886401]

BACKGROUND: The antipyretic effectiveness of rectal versus oral acetaminophen is not well established. This study is designed to compare the antipyretic effectiveness of two rectal acetaminophen doses (15 mg/kg) and (35 mg/kg), to the standard oral dose of 15 mg/kg. METHODS: This is a randomized, double-dummy, double-blind study of 51 febrile children, receiving one of three regimens of a single acetaminophen dose: 15 mg/kg orally, 15 mg/kg rectally, or 35 mg/kg rectally. Rectal temperature was monitored at baseline and hourly for a total of six hours. The primary outcome of the study, time to maximum antipyresis, and the secondary outcome of time to temperature reduction by at least 1°C were analyzed by one-way ANOVA. Two-way ANOVA with repeated measures over time was used to compare the secondary outcome: change in temperature from baseline at times1, 2, 3, 4, 5, and 6 hours among the three groups. Intent-to-treat analysis was planned. RESULTS: No significant differences were found among the three groups in the time to maximum antipyresis (overall mean = 3.6 hours; 95% CI: 3.2–4.0), time to fever reduction by 1°C or the mean hourly temperature from baseline to 6 hours following dose administration. Hypothermia (temperature < 36.5°C) occurred in 11(21.6%) subjects, with the highest proportion being in the rectal high-dose group. CONCLUSION: Standard (15 mg/kg) oral, (15 mg/kg) rectal, and high-dose (35 mg/kg) rectal acetaminophen have similar antipyretic effectiveness

Assessing the impact of professional lactation support frequency, duration and delivery form on exclusive breastfeeding in Lebanese mothers.

BackgroundThe optimal frequency, duration, and form of professional lactation support needed to continue exclusive breastfeeding (EBF) for six months have not yet been specifically identified. This study investigates the association between six-month EBF and the frequency, duration, and form (face-to-face vs. telephone contact) of professional lactation support in a cohort of Lebanese mothers, and explores barriers to EBF during the first six months postpartum.MethodsAn observational study was nested in a breastfeeding support randomized controlled trial. Secondary analysis of data from 159 trial participants who received professional lactation support was conducted. (1) Six-month EBF with professional lactation support frequency, duration, and form was investigated using bivariate and multivariate regression analyses. (2) Barriers to breastfeeding were explored using content analysis of narrative data collected about breastfeeding mothers by the lactation experts.ResultsSix-month EBF was achieved by 57/159 (35.8%) participants. Professional lactation support was received by more mothers continuing six months of EBF (100% vs. 83.3%, p = 0.001). In crude analysis, those mothers had a higher number of overall contacts with lactation experts (mean ± SD of 9.5 ± 2.9 vs. 7.0 ± 4.4, p = 0.001), and longer duration of face-to-face contacts (mean ± SD of 261.9 ± 209.1 vs. 201.0 ± 117.4 minutes, p = 0.035). In adjusted analysis, frequencies of overall and of telephone contacts with the lactation experts were positively associated with six-month EBF (OR = 1.15; 95% CI: 1.04 to 1.27, p = 0.007; OR = 1.12; 95% CI: 1.00 to 1.26, p = 0.05; respectively). Participants discontinuing EBF early were described as inexperienced, lacking breastfeeding knowledge, concerned about milk insufficiency, and showing negative attitudes towards night feeds.ConclusionNeed-based telephone contact augmenting face-to-face professional lactation support may positively influence six-month EBF. Early identification of mothers at risk for early discontinuation of EBF can help tailor interventions specific to their concerns

Validation of the Arabic Maternal postpartum quality of life questionnaire among Lebanese women: A cohort study.

BackgroundThe postpartum period is an important phase in a woman's life. Yet, there is a paucity of validated instruments that assess maternal postpartum quality of life issues. The aim of this study is to describe the adaptation and validation of the Arabic version of the Maternal Postpartum Quality of Life (MAPP-QOL) questionnaire.MethodsThis instrument validation cohort study tested an adapted Arabic version of the MAPP-QOL questionnaire on a convenience sample of 485 healthy Lebanese postpartum women. The MAPP-QOL reliability and validity were investigated by conducting Exploratory Factor Analysis using Principal Component Analysis, and by correlating the participants' MAPP-QOL scores with their scores on the Arabic Maternal Breastfeeding Evaluation Scale (MBFES-A), age, and education. Confirmatory Factor Analysis was conducted to examine how well the original factor structure of MAPP-QOL fits with our observed data using STATA 14. All other statistical analyses were done using SPSS version 23.ResultsThe Cronbach's alpha reliability coefficient of the Arabic MAPP-QOL was 0.90. Exploratory factor analysis revealed the following five components: Functioning (11 items, Cronbach's alpha of 0.82), Socioeconomic (9 items, Cronbach's alpha of 0.81), Relational (9 items, Cronbach's alpha of 0.75), Psychological (4 items, Cronbach's alpha of 0.74), and Health (6 items, Cronbach's alpha of 0.59). The overall Arabic MAPP-QOL score was positively but weakly correlated with the MBFES-A score (r = 0.177, p ConclusionsThe Arabic MAPP-QOL has good psychometric properties and may be a useful tool for clinicians and researchers interested in measuring maternal postpartum quality of life. Further replication of our findings in other Arab contexts is needed

Knowledge and attitudes of Lebanese women towards Baby Friendly Hospital Initiative practices.

BackgroundThe World Health Organization and United Nations Children's Fund launched the Baby Friendly Hospital Initiative (BFHI) to encourage best infant breastfeeding practices immediately after birth. In Lebanon, few hospitals are currently accredited as Baby Friendly.AimTo assess the knowledge of Lebanese women of BFHI steps, and to explore their attitudes towards Baby Friendly Hospitals, Skin-to-Skin Contact and Kangaroo Care practices.MethodsA cross-sectional survey of a random sample of healthy pregnant women from Lebanon's six governorates.ResultsThe mean (SD) age of the participants (N = 517) was 28.6 (4.7) years. Most participants were unfamiliar with the terms Baby Friendly hospital (93.7%), skin-to-skin contact or kangaroo care (75%), or were inadequately instructed on how to initiate (54.2%) or continue (46.2%) breastfeeding. However, when provided with information about the benefits of BFHI practices, most mothers (> 90%) stated that they would deliver in Baby Friendly hospitals. About 68.4% of mothers refused to give donor human milk to their sick premature infants because of religious beliefs. Knowledge of Baby Friendly hospitals was significantly associated with university education (p = 0.029), higher monthly income (p = 0.042), and previous experiences of skin-to-skin contact (pConclusionThere is a need for national awareness campaigns that address both the numerous advantages of the BFHI practices and Lebanese women's knowledge gaps about these practices. Such knowledge will help scale up the implementation of BFHI practices in hospitals in Lebanon, thus increasing breastfeeding rates and positively impacting the health of infants and mothers
