Estimated Childhood Lead Exposure From Drinking Water in Chicago.

JAMA Pediatrics

There is no level of lead in drinking water considered to be safe, yet lead service lines are still commonly used in water systems across the US.

To identify the extent of lead-contaminated drinking water in Chicago, Illinois, and model its impact on children younger than 6 years.

For this cross-sectional study, a retrospective assessment was performed of lead exposure based on household tests collected from January 2016 to September 2023. Tests were obtained from households in Chicago that registered for a free self-administered testing service for lead exposure. Machine learning and microsimulation were used to estimate citywide childhood lead exposure.

Lead-contaminated drinking water, measured in parts per billion.

Number of children younger than 6 years exposed to lead-contaminated water.

A total of 38 385 household lead tests were collected. An estimated 68% (95% uncertainty interval, 66%-69%) of children younger than 6 years were exposed to lead-contaminated water, corresponding to 129 000 children (95% uncertainty interval, 128 000-131 000 children). Ten-percentage-point increases in block-level Black and Hispanic populations were associated with 3% (95% CI, 2%-3%) and 6% (95% CI, 5%-7%) decreases in odds of being tested for lead and 4% (95% CI, 3%-6%) and 11% (95% CI, 10%-13%) increases in having lead-contaminated drinking water, respectively.

These findings indicate that childhood lead exposure is widespread in Chicago, and racial inequities are present in both testing rates and exposure levels. Machine learning may assist in preliminary screening for lead exposure, and efforts to remediate the effects of environmental racism should involve improving outreach for and access to lead testing services.

Basic Environmental Supports for Positive Brain and Cognitive Development in the First Year of Life.

JAMA Pediatrics

Defining basic psychosocial resources to facilitate thriving in the first year of life could tangibly inform policy and enhance child development worldwide.

To determine if key environmental supports measured as a thrive factor (T-factor) in the first year of life positively impact brain, cognitive, and socioemotional outcomes through age 3.

This prospective longitudinal cohort study took place at a Midwestern academic medical center from 2017 through 2022. Participants included singleton offspring oversampled for those facing poverty, without birth complications, congenital anomalies, or in utero substance exposures (except cigarettes and marijuana) ascertained prenatally and followed up prospectively for the first 3 years of life. Data were analyzed from March 9, 2023, through January 3, 2024.

Varying levels of prenatal social disadvantage advantage and a T-factor composed of environmental stimulation, nutrition, neighborhood safety, positive caregiving, and child sleep.

Gray and white matter brain volumes and cortical folding at ages 2 and 3 years, cognitive and language abilities at age 3 years measured by the Bayley-III, and internalizing and externalizing symptoms at age 2 years measured by the Infant-Toddler Social and Emotional Assessment.

The T-factor was positively associated with child cognitive abilities (β = 0.33; 95% CI, 0.14-0.52), controlling key variables including prenatal social disadvantage (PSD) and maternal cognitive abilities. The T-factor was associated with child language (β = 0.36; 95% CI, 0.24-0.49), but not after covarying for PSD. The association of the T-factor with child cognitive and language abilities was moderated by PSD (β = -0.32; 95% CI, -0.48 to -0.15 and β = -0.36; 95% CI, -0.52 to -0.20, respectively). Increases in the T-factor were positively associated with these outcomes, but only for children at the mean and 1 SD below the mean of PSD. The T-factor was negatively associated with child externalizing and internalizing symptoms over and above PSD and other covariates (β = -0.30; 95% CI, -0.52 to -0.08 and β = -0.32; 95% CI, -0.55 to -0.09, respectively). Increasing T-factor scores were associated with decreases in internalizing symptoms, but only for children with PSD 1 SD above the mean. The T-factor was positively associated with child cortical gray matter above PSD and other covariates (β = 0.29; 95% CI, 0.04-0.54), with no interaction between PSD and T-factor.

Findings from this study suggest that key aspects of the psychosocial environment in the first year impact critical developmental outcomes including cognitive, brain, and socioemotional development at age 3 years. This suggests that environmental resources and enhancement in the first year of life may facilitate every infant's ability to thrive, setting the stage for a more positive developmental trajectory.

Telephone triage and dispatch of ambulances to patients with suspected and verified acute stroke - a descriptive study.

Prehospital Emergency Care

In this study we aimed to explore EMCC triage of suspected and confirmed stroke patients to gain more knowledge about the initial phase of the acute stroke response chain. Accurate dispatch at the Emergency Medical Communication Center (EMCC) is crucial for optimal resource utilization in the prehospital service, and early identification of acute stroke is known to improve patient outcome.

We conducted a descriptive retrospective study based on data from the Emergency Department and EMCC records at a comprehensive stroke center in Oslo, Norway, during a six-month period (2019-2020). Patients dispatched with EMCC stroke criteria and/or discharged with a stroke diagnosis were included. We identified EMCC true positive, false positive and false negative stroke patients and estimated EMCC stroke sensitivity and positive predictive value (PPV). Furthermore, we analyzed prehospital time intervals and identified patient destinations to gain knowledge on ambulance services assessments.

We included 1298 patients. EMCC stroke sensitivity was 77% (95% CI: 72 - 82%), and PPV was 16% (95% CI: 14 - 18%). EMCC false negative stroke patients experienced an increased median prehospital delay of 11 min (p < 0.001). Upon arrival at the scene, 68% of the EMCC false negative patients were identified as suspected stroke cases by the ambulance services. Similarly, 68% of the false positive stroke patients were either referred to a GP, out-of-hours GP acute clinic, local hospitals or left at the scene by the ambulance services, indicating that no obvious stroke symptoms were identified by ambulance personnel upon arrival at the scene.

This study reveals a high EMCC stroke sensitivity and an extensive number of false positive stroke dispatches. By comparing the assessments made by both the EMCC and the ambulance service, we have identified specific patient groups that should be the focus for future research efforts aimed at improving the sensitivity and specificity of stroke recognition in the EMCC.

Specialty drug use for autoimmune conditions varies by race and wage among employees with employer-sponsored health insurance.

Journal of burn care & research

The relationship between race and ethnicity, wage status, and specialty medication (SpRx) use among employees with autoimmune conditions (AICs) is poorly understood. Insight into sociodemographic variations in use of these medications can inform health equity improvement efforts.

To assess the association of race and ethnicity and wage status on SpRx use and adherence patterns among employees with AICs enrolled in employer-sponsored health insurance.

In this observational, retrospective cohort analysis, data were obtained from the IBM Watson MarketScan database for calendar year 2018. Employees were separated into race and ethnicity subgroups based on employer-provided data. Midyear employee wage data were used to allocate employees into the following annual income quartiles: $47,000 or less, $47,001-$71,000, $71,001-$106,000, and $106,001 or more. The lowest quartile was further divided into 2 groups ($35,000 or less and $35,001-$47,000) to better evaluate subgroup differences. Outcomes included monthly days SpRx-AIC supply, proportion of days covered (PDC), and medication discontinuation rates. Generalized linear regressions were used to assess differences while adjusting for patient and other characteristics.

From a sample of more than 2,000,000 enrollees, race and ethnicity data were available for 617,117 (29.8%). Of those, 47,839 (7.8%) were identified as having an AIC of interest, with prevalence rates of AICs differing by race within wage categories. Among those with AICs, 5,358 (11.2%) had filled at least 1 SpRx-AIC prescription. Following adjustment, except for the highest wage category, prevalence of SpRx-AIC use was significantly less among Black and Hispanic subpopulations. Black patients had significantly lower SpRx-AIC use rates than White patients (≤$35,000: 4.9 vs 9.4%, >$35,000-$47,000: 5.5 vs 10.6%, >$47,000-$71,000: 8.5 vs 11.1%, and >$71,000-$106,000: 9.1 vs 12.7%; P <0.001 for all). For Hispanic patients, prevalence rates were significantly lower than White patients in 3 different wage categories (≤$35,000: 4.5 vs 9.4%, >$35,000-$47,000: 6.1 vs 10.6%, and >$71,000-$106,000: 8.6 vs 12.7%; P < 0.001). PDC and 90-day discontinuation rates did not differ among race and ethnicity groups within the respective wage bands.

Race and ethnicity and wage-related disparities exist in SpRx use, but not PDC or discontinuation rates for treatment of AICs among non-White and low-income populations with employer-sponsored insurance, and may adversely impact clinical outcomes.

Frequency and features of medical emergencies at a teaching dental hospital in Saudi Arabia: a 14-year retrospective observational study.

Prehospital Emergency Care

This study aimed to determine the nature, frequency, and characteristics of medical emergencies occurring at the King Abdulaziz University Dental Hospital.

The incident reports of medical emergencies recorded at the King Abdulaziz University Dental Hospital from January 2008 to December 2022 were retrospectively reviewed. The annual/overall incidence of medical emergency events was calculated per 100,000 patients. The following characteristics of the patients/events were evaluated: age, gender, operator, procedure, location, timing of treatment, administration of local anesthesia, past medical history, symptoms, diagnosis, outcome, and disposition. Multivariable logistic regression models were used to investigate the associations of these characteristics with two outcomes: syncope and transfer to the emergency room (ER).

The incidence of emergency events was 17.4 per 100,000 patients. Syncope and hypoglycemia were the most common emergencies. Most incidents recovered, with only 13% requiring transfer to the ER. Undergoing no procedure and American Society of Anesthesiologists (ASA) class 2,3 were associated with syncope. Undergoing a general dental procedure, ASA class 2,3, and a diagnosis other than hypoglycemia and syncope were associated with transfer to the ER.

The incidence of medical emergencies was low. Dental practitioners need to remain aware of the contributing factors, such as past medical history and anxiety, but medical emergencies can occur in healthy individuals as well. Preparation of the dental office, training of the personnel, and proper recording of the events are essential components of a well-established medical emergency protocol in dental institutions.

Patient experience of non-conveyance in the EMS of Southwest Finland: a descriptive survey study.

Prehospital Emergency Care

Emergency Medical Services are dispatched more frequently than before. However, many non-urgent patients do not need ambulance transportation to a healthcare facility after evaluation and treatment on scene. This study explored the experiences of non-conveyed patients. Our research questions were: (1) How have non-conveyed patients experienced the service received from EMS? (2) Does a patient's age, gender, or time of the emergency call impact the patient's experience?

This descriptive survey study examined non-conveyed Emergency Medical Services patients in the Wellbeing Services County of Southwest Finland. The study period was from March 1, 2023, to March 31, 2023. The study population was 1017. They received a questionnaire that was sent by mail. The questionnaire was formed based on questions previously used in four different questionnaires. We received 247 answers (24.3% response rate). Percentages, medians with interquartile ranges, and non-parametric tests were used in the descriptive analyses.

Non-conveyed patients were very satisfied with the paramedics' expertise and behavior, their ability to meet their individual needs, the sense of safety provided by the paramedics, and the instructions given to the patients. Time to receive help (19% rated 3 or less on a scale from 1 to 5), how paramedics introduced themselves (16.5%), and satisfaction with non-conveyance decisions (14.6%) were more frequently rated lower than other areas. Further, pain management stood out in the less favorable evaluations. Still, patients' experiences of the service were positive. The age group, gender, or time of the emergency call were not associated with patient experience.

Patients were very satisfied with the paramedics' interpersonal skills. A more focused approach to pain management and developing EMS to ensure faster patient outreach and clearer explanations of non-conveyance decisions could further enhance the patient experience.

Reducing medication errors on emergency department discharge: Evaluation of a collaborative pharmacist-medical officer discharge prescription planning model in a tertiary hospital emergency short stay unit.

EMA - Emergency Medicine Australasia

To implement and evaluate the impact of a collaborative pharmacist-medical officer model of planning discharge prescriptions, Partnered Pharmacist Discharge Prescription Planning (PPDPP) on the safe use of medicines on discharge in an ED short stay unit (SSU).

A prospective pre- and post-intervention study measured the proportion of medication errors on discharge prescriptions from the SSU using the Five Rights (5Rs) method. Pharmacists assessed discharge prescriptions generated by the medical officers (MO) during the pre-intervention phase (standard practice). During the PPDPP phase, pharmacists planned electronic prescriptions in consultation with MO and completed prescriptions were independently assessed by another pharmacist.

There were 163 and 147 prescriptions collected during the pre- and post-intervention phases, respectively. There was a significant difference in the proportion of discharge prescriptions that met all 5Rs between the standard practice (47.2%) and PPDPP phase (91.8%) (P < 0.001). There was no statistical difference seen in the mean time taken from discharge decision to prescriptions given to patients or patients leaving the SSU between the two phases. There was a non-statically significant trend towards a decrease in time taken for patients to obtain prescriptions by 11% (P = 0.16) and for actual departure time by 6% (P = 0.46). Additionally, the proportion of opioids prescribed as one of the high-risk medication classes reduced from 23.8% to 16.2% (P = 0.023) with the PPDPP model.

The PPDPP model improved medications safety on discharge from the ED SSU. The PPDPP did not impact patient flow parameters as measured in this study.

Derivation of the Difficult Airway Physiological Score (DAPS) in adults undergoing endotracheal intubation in the emergency department.

Prehospital Emergency Care

Prediction of serious outcomes among patients with physiological instability is crucial in airway management. In this study, we aim to develop a score to predict serious outcomes following intubation in critically ill adults with physiological instability by using clinical and laboratory parameters collected prior to intubation.

This single-center analytical cross-sectional study was conducted in the Emergency Department from 2016 to 2020. The airway score was derived using the transparent reporting of a multivariable prediction model for individual prognosis or diagnosis (TRIPOD) methodology. To gauge model's performance, the train-test split technique was utilized. The discrete random number generation approach was used to divide the dataset into two groups: development (training) and validation (testing). The validation dataset's instances were used to calculate the final score, and its validity was measured using ROC analysis and area under the curve (AUC). By computing the Youden's J statistic using the metrics sensitivity, specificity, positive predictive value, and negative predictive value, the discriminating factor of the additive score was determined.

The mean age of the 1021 patients who needed endotracheal intubations was 52.2 years (± 17.5), and 632 (62%) of them were male. In the development dataset, there were 527 (64.9%) physiologically difficult airways, 298 (36.7%) post-intubation hypotension, 124 (12%) cardiac arrest, 347 (42.7%) shock index > 0.9, and 456 [56.2%] instances of pH < 7.3. On the contrary, in the validation dataset, there were 143 (68.4%) physiologically difficult airways, 33 (15.8%) post-intubation hypotension, 41 (19.6%) cardiac arrest, 87 (41.6%) shock index > 0.9, and 121 (57.9%) had pH < 7.3, respectively. There were 12 variables in the difficult airway physiological score (DAPS), and a DAPS of 9 had an area under the curve of 0.857. The accuracy of DAPS was 77%, the sensitivity was 74%, the specificity was 83.3%, and the positive predictive value was 91%.

DAPS demonstrated strong discriminating ability for anticipating physiologically challenging airways. The proposed model may be helpful in the clinical setting for screening patients who are at high risk of deterioration.

Social Determinants of Health and Redirection of Care for Infants Born Extremely Preterm.

JAMA Pediatrics

Redirection of care refers to withdrawal, withholding, or limiting escalation of treatment. Whether maternal social determinants of health are associated with redirection of care discussions merits understanding.

To examine associations between maternal social determinants of health and redirection of care discussions for infants born extremely preterm.

This is a retrospective analysis of a prospective cohort of infants born at less than 29 weeks' gestation between April 2011 and December 2020 at 19 National Institute of Child Health and Human Development Neonatal Research Network centers in the US. Follow-up occurred between January 2013 and October 2023. Included infants received active treatment at birth and had mothers who identified as Black or White. Race was limited to Black and White based on service disparities between these groups and limited sample size for other races. Maternal social determinant of health exposures were education level (high school nongraduate or graduate), insurance type (public/none or private), race (Black or White), and ethnicity (Hispanic or non-Hispanic).

The primary outcome was documented discussion about redirection of infant care. Secondary outcomes included subsequent redirection of care occurrence and, for those born at less than 27 weeks' gestation, death and neurodevelopmental impairment at 22 to 26 months' corrected age.

Of the 15 629 infants (mean [SD] gestational age, 26 [2] weeks; 7961 [51%] male) from 13 643 mothers, 2324 (15%) had documented redirection of care discussions. In unadjusted comparisons, there was no significant difference in the percentage of infants with redirection of care discussions by race (Black, 1004/6793 [15%]; White, 1320/8836 [15%]) or ethnicity (Hispanic, 291/2105 [14%]; non-Hispanic, 2020/13 408 [15%]). However, after controlling for maternal and neonatal factors, infants whose mothers identified as Black or as Hispanic were less likely to have documented redirection of care discussions than infants whose mothers identified as White (Black vs White adjusted odds ratio [aOR], 0.84; 95% CI, 0.75-0.96) or as non-Hispanic (Hispanic vs non-Hispanic aOR, 0.72; 95% CI, 0.60-0.87). Redirection of care discussion occurrence did not differ by maternal education level or insurance type.

For infants born extremely preterm, redirection of care discussions occurred less often for Black and Hispanic infants than for White and non-Hispanic infants. It is important to explore the possible reasons underlying these differences.

Cost-Effectiveness of Strategies for Treatment Timing for Perinatally Acquired Hepatitis C Virus.

JAMA Pediatrics

Prevalence of chronic hepatitis C virus (HCV) infection among pregnant people is increasing in the US. HCV is transmitted vertically in 7% to 8% of births. Direct-acting antiviral (DAA) therapy was recently approved for children with HCV who are 3 years or older. The clinical and economic impacts of early DAA therapy for young children with HCV, compared with treating at older ages, are unknown.

To develop a state-transition model to project clinical and economic outcomes for children with perinatally acquired HCV to investigate the cost-effectiveness of treating at various ages.

The study team modeled the natural history of perinatally acquired HCV to simulate disease progression and costs of a simulated a cohort of 1000 US children with HCV from 3 years old through death. Added data were analyzed January 5, 2021, through July 1, 2022.

The study compared strategies offering 8 weeks of DAA therapy at 3, 6, 12, or 18 years old, as well as a comparator of never treating HCV.

Outcomes of interest include life expectancy from 3 years and average lifetime per-person health care costs. Other clinical outcomes include cases of cirrhosis, decompensated cirrhosis, and hepatocellular carcinoma (HCC).

The study team projected that treating HCV at 3 years old was associated with lower mean lifetime per-person health care costs ($148 162) than deferring treatment until 6 years old ($164 292), 12 years old ($171 909), or 18 years old ($195 374). Projected life expectancy was longest when treating at 3 years old (78.36 life years [LYs]) and decreased with treatment deferral until 6 years old (76.10 LYs), 12 years old (75.99 LYs), and 18 years old (75.46 LYs). In a cohort of 1000 children with perinatally acquired HCV, treating at 3 years old prevented 89 projected cases of cirrhosis, 27 cases of HCC, and 74 liver-related deaths compared with deferring treatment until 6 years old. In sensitivity analyses, increasing loss to follow-up led to even greater clinical benefits and cost savings with earlier treatment.

These study results showed that DAA therapy for 3-year-old children was projected to reduce health care costs and increase survival compared with deferral until age 6 years or older. Measures to increase DAA access for young children will be important to realizing these benefits.

Adverse Effects After Prehospital Administration of Naloxone by Bystanders: A Preliminary Study.

Prehospital Emergency Care

Opioid use disorder is a cause of significant morbidity and mortality. In order to reverse opioid overdose as quickly as possible, many institutions and municipalities have encouraged people with no professional medical training to carry and administer naloxone. This study sought to provide preliminary data for research into the rates of adverse effects of naloxone when administered by bystanders compared to Emergency Medical Services (EMS) personnel, since this question has not been studied previously.

This was a retrospective cohort study performed at an urban, tertiary, academic medical center that operates its own EMS service. A consecutive sample of patients presenting to EMS with opioid overdose requiring naloxone was separated into two groups based on whether naloxone was administered by bystanders or by EMS personnel. Each group was analyzed to determine the incidence of four pre-specified adverse events.

There was no significant difference in the rate of adverse events between the bystander (19%) and EMS (16%) groups (OR = 1.23; 95% CI, 0.63 - 2.32; P = .499) in this small sample. Based on these initial results, a study would need a sample size of 6,188 in order to reach this conclusion with 80% power. Similarly, there were no significant differences in the rates of any of the individual adverse events. Secondary analysis of patients' demographics showed differences between the two groups which generate hypotheses for further investigation of disparities in naloxone administration.

This preliminary study provides foundational data for further investigation of naloxone administration by bystanders. Adverse events after the prehospital administration of naloxone are rare, and future studies will require large sample sizes. These preliminary data did not demonstrate a statistically significant difference in adverse event rates when comparing naloxone administration by bystanders and EMS clinicians. This study provides data that will be useful for conducting further research on multiple facets of this topic.
