RESUMO

OBJECTIVES: Acute brain dysfunction (ABD) in pediatric sepsis has a prevalence of 20%, but can be difficult to identify. Our previously validated ABD computational phenotype (CP ABD ) used variables obtained from the electronic health record indicative of clinician concern for acute neurologic or behavioral change. We tested whether the CP ABD has better diagnostic performance to identify confirmed ABD than other definitions using the Glasgow Coma Scale or delirium scores. DESIGN: Diagnostic testing in a curated cohort of pediatric sepsis/septic shock patients. SETTING: Quaternary freestanding children's hospital. SUBJECTS: The test dataset comprised 527 children with sepsis/septic shock managed between 2011 and 2021 with a prevalence (pretest probability) of confirmed ABD of 30% (159/527). MEASUREMENTS AND MAIN RESULTS: CP ABD was based on use of neuroimaging, electroencephalogram, and/or administration of new antipsychotic medication. We compared the performance of the CP ABD with three GCS/delirium-based definitions of ABD-Proulx et al, International Pediatric Sepsis Consensus Conference, and Pediatric Organ Dysfunction Information Update Mandate. The posttest probability of identifying ABD was highest in CP ABD (0.84) compared with other definitions. CP ABD also had the highest sensitivity (83%; 95% CI, 76-89%) and specificity (93%; 95% CI, 90-96%). The false discovery rate was lowest in CP ABD (1-in-6) as was the false omission rate (1-in-14). Finally, the prevalence threshold for the definitions varied, with the CP ABD being the definition closest to 20%. CONCLUSIONS: In our curated dataset of pediatric sepsis/septic shock, CP ABD had favorable characteristics to identify confirmed ABD compared with GCS/delirium-based definitions. The CP ABD can be used to further study the impact of ABD in studies using large electronic health datasets.

RESUMO

OBJECTIVES: Avascular necrosis (AVN) is a rare, but serious, complication after sepsis in adults. We sought to determine if sepsis is associated with postillness diagnosis of AVN, as well as potential-associated risk factors for AVN in children with sepsis. DESIGN: Retrospective observational study. SETTING: Single academic children's hospital. PATIENTS: Patients less than 18 years treated for sepsis or suspected bacterial infection from 2011 to 2017. Patients who developed AVN within 3 years after sepsis were compared with patients who developed AVN after suspected bacterial infection and with patients with sepsis who did not develop AVN. INTERVENTION: None. MEASUREMENTS AND MAIN RESULTS: AVN was determined using International Classification of Diseases, 9th Edition/10th Edition codes and confirmed by chart review. The prevalence of AVN after sepsis was 0.73% (21/2,883) and after suspected bacterial infection was 0.43% (53/12,276; risk difference, 0.30; 95% CI, 0.0-0.63; p = 0.05). Compared with 43 sepsis controls without AVN, AVN in the 21 sepsis cases was associated with being older, having sickle cell disease and malignancy, higher body mass index, unknown source of infection, and low platelet count in the first 7 days of sepsis. Half of sepsis patients were treated with corticosteroids, and higher median cumulative dose of steroids was associated with AVN (23.2 vs 5.4 mg/kg; p < 0.01). Older age at infection (odds ratio [OR], 1.3; 95% CI, 1.1-1.4), malignancy (OR, 8.8; 95% CI, 2.6-32.9), unknown site of infection (OR, 12.7; 95% CI, 3.3-48.6), and minimal platelet count less than 100,000/µL in first 7 days of sepsis (OR, 5.0; 95% CI, 1.6-15.4) were identified as potential risk factors for AVN after sepsis following adjustment for multiple comparisons. CONCLUSIONS: Although rare, sepsis was associated with a higher risk of subsequent AVN than suspected bacterial infection in children. Older age, malignancy, unknown site of infection, and minimum platelet count were potential risk factors for AVN after sepsis.

RESUMO

OBJECTIVES: To validate a computational phenotype that identifies acute brain dysfunction (ABD) based on clinician concern for neurologic or behavioral changes in pediatric sepsis. DESIGN: Retrospective observational study. SETTING: Single academic children's hospital. PATIENTS: Four thousand two hundred eighty-nine index sepsis episodes. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: An existing computational phenotype of ABD was optimized to include routinely collected variables indicative of clinician concern for acute neurologic or behavioral change (completion of CT or MRI, electroencephalogram, or new antipsychotic administration). First, the computational phenotype was compared with an ABD reference standard established from chart review of 527 random sepsis episodes to determine criterion validity. Next, the computational phenotype was compared with a separate validation cohort of 3,762 index sepsis episodes to determine content and construct validity. Criterion validity for the final phenotype had sensitivity 83% (95% CI, 76-89%), specificity 93% (90-95%), positive predictive value 84% (77-89%), and negative predictive value 93% (90-96%). In the validation cohort, the computational phenotype identified ABD in 35% (95% CI 33-36%). Content validity was demonstrated as those with the ABD computational phenotype were more likely to have characteristics of neurologic dysfunction and severe illness than those without the ABD phenotype, including nonreactive pupils (15% vs 1%; p < 0.001), Glasgow Coma Scale less than 5 (44% vs 12%; p < 0.001), greater than or equal to two nonneurologic organ dysfunctions (50% vs 25%; p < 0.001), and need for intensive care (81% vs 65%; p < 0.001). Construct validity was demonstrated by higher odds for mortality (odds ratio [OR], 6.9; 95% CI, 5.3-9.1) and discharge to rehabilitation (OR, 11.4; 95% CI 7.4-17.5) in patients with, versus without, the ABD computational phenotype. CONCLUSIONS: A computational phenotype of ABD indicative of clinician concern for new neurologic or behavioral change offers a valid retrospective measure to identify episodes of sepsis that involved ABD. This computational phenotype provides a feasible and efficient way to study risk factors for and outcomes from ABD using routinely collected clinical data.

RESUMO

OBJECTIVES: Emergency department (ED) visits for behavioral health (BH) emergencies continue to rise, and institutions across the country encounter barriers and struggle to put BH processes in place to address their needs. After learning of an unanticipated closure of a local psychiatric crisis response center (CRC), our ED implemented quality improvement interventions to respond to an acute surge of BH patients. METHODS: Interventions included an enhanced BH database, the role of social workers as extenders, shared electronic health record documentation, increased staffing, clinical pathway updates, and processes to improve communication. We aimed to develop a care model to maintain safe care with timely evaluation and patient disposition despite an anticipated surge of ED patients. RESULTS: After the CRC closure, 7383 patients met our cohort definition over 18 months, whereas 4326 patients met the cohort definition in the 18 months prior the CRC closure. Of the total patients seen in the study period, 42% were evaluated by the ED team with psychiatry and social work, and the median length of stay for discharged patients evaluated by this team decreased from 4.2 hours to 3.5 hours after CRC closure. CONCLUSIONS: A multifaceted approach allowed our ED to successfully respond to an unexpected surge of BH patients. Other institutions may be able to apply a population health and quality improvement approach when addressing the rising prevalence of ED BH visits. Future studies and practices should explore the optimal role of the acute care setting in the continuum of care of these patients.

RESUMO

BACKGROUND Our objectives were to evaluate geographic access to lung cancer treatment modalities in North Carolina and to characterize how practice patterns are changing over time. We hypothesized that rural patients would be less likely to undergo treatment compared to urban patients, with widening disparities over time.METHODS We identified patients with Stage I non-small cell lung cancer (NSCLC) from 2006 to 2015 using the North Carolina Central Cancer Registry linked with Medicaid, Medicare, and private insurance claims. The primary outcome was first-course treatment: surgery, radiation, or no treatment. Calendar years were split into earlier (2006-2010) and later (2011-2015) periods. We estimated the adjusted odds ratio (OR) of rural/urban status and time period with 1) surgery and 2) any treatment (surgery or radiation) using multivariable logistic regression.RESULTS Among 5504 patients, 3206 (58%) underwent surgery as initial therapy, 1309 (24%) received radiation as initial therapy, and 989 (18%) had no therapy. There were no rural-urban disparities in treatment patterns. For rural and urban patients, the odds of surgery decreased over time and the odds of radiation increased. We also found that only 48% of those receiving no treatment ever reached a surgeon or radiation oncologist.LIMITATIONS This was an insured, single-state population. Treatment preferences are unknown.CONCLUSIONS Among all treated patients, whether urban or rural, there was increasing use of radiation and decreasing use of surgery over time. Many patients without treatment never had a consultation with a surgeon/radiation oncologist, and this is an actionable target for improving treatment access for early-stage NSCLC.

RESUMO

Extreme weather and climate events, such as heat waves, cyclones, and floods, are an expression of climate variability. These events and events influenced by climate change, such as wildfires, continue to cause significant human morbidity and mortality and adversely affect mental health and well-being. Although adverse health impacts from extreme events declined over the past few decades, climate change and more people moving into harm's way could alter this trend. Long-term changes to Earth's energy balance are increasing the frequency and intensity of many extreme events and the probability of compound events, with trends projected to accelerate under certain greenhouse gas emissions scenarios. While most of these events cannot be completely avoided, many of the health risks could be prevented through building climate-resilient health systems with improved risk reduction, preparation, response, and recovery. Conducting vulnerability and adaptation assessments and developing health system adaptation plans can identify priority actions to effectively reduce risks, such as disaster risk management and more resilient infrastructure. The risks are urgent, so action is needed now.

RESUMO

OBJECTIVE: Intravenous acetaminophen/paracetamol (APAP) is well documented to cause hypotension. Since the patients receiving intravenous APAP are usually critically ill, any severe hemodynamic changes, as with those associated with APAP, can be life-threatening. The mechanism underlying this dangerous iatrogenic effect of APAP was unknown. Approach and Results: Here, we show that intravenous APAP caused transient hypotension in rats, which was attenuated by the Kv7 channel blocker, linopirdine. APAP metabolite N-acetyl-p-benzoquinone imine caused vasodilatation of rat mesenteric arteries ex vivo. This vasodilatation was sensitive to linopirdine and also the calcitonin gene-related peptide antagonist, BIBN 4096. Further investigation revealed N-acetyl-p-benzoquinone imine stimulates calcitonin gene-related peptide release from perivascular nerves, causing a cAMP-dependent activation of Kv7 channels. We also show that N-acetyl-p-benzoquinone imine enhances Kv7.4 and Kv7.5 channels overexpressed in oocytes, suggesting that it can activate Kv7.4 and Kv7.5 channels directly, to elicit vasodilatation. CONCLUSIONS: Direct and indirect activation of Kv7 channels by the APAP metabolite N-acetyl-p-benzoquinone imine decreases arterial tone, which can lead to a drop in blood pressure. Our findings provide a molecular mechanism and potential preventive intervention for the clinical phenomenon of intravenous APAP-dependent transient hypotension.

RESUMO

OBJECTIVE: The aims of this study were to evaluate trends over time in computed tomography (CT) scan utilization after implementation of a clinical pathway in a tertiary care children's hospital emergency department (ED), to determine how ED throughput differs by CT utilization, and to determine provider reasoning for obtaining head CT in low-risk patients. METHODS: This was a retrospective cohort study of patients 21 years or younger discharged from our ED with head trauma (Glasgow Coma Scale score ≥13 and a head trauma International Classification of Diseases code) over a 5-year period, starting 1 year after pathway implementation (January 2012 to December 2016). A manual chart review of 10% of patients who received a CT was performed to determine reasoning for CT utilization and guideline compliance. RESULTS: In total, 6.3% (95% confidence interval [CI], 5.9%-6.6%) of 21,129 discharged patients received a head CT, decreasing annually by an average of 0.9%. Pediatricians were more likely to obtain a CT than pediatric emergency medicine physicians after adjusting for acuity (odds ratio, 1.37; 95% CI, 1.02-1.82). Those who received a CT stayed 90 minutes longer (95% CI, 79-101 minutes) than those who did not after propensity score matching. Thirty percent of patients who received a CT in our manual chart review met low-risk Pediatric Emergency Care Applied Research Network criteria. CONCLUSIONS: Head CT rates in patients with minor head trauma consistently decreased each year after guideline implementation. Children who received head CT did not have prolonged lengths of stay compared with those who did not. A minority of patients who received a CT and were discharged met low-risk criteria by standardized guidelines.

RESUMO

STUDY OBJECTIVE: Sepsis recognition is a clinical challenge in children. We aim to determine whether peripheral blood gene expression profiles are associated with pathogen type and sepsis severity in children with suspected sepsis. METHODS: This was a prospective pilot observational study in a tertiary pediatric emergency department with a convenience sample of children enrolled. Participants were older than 56 days and younger than 18 years, had suspected sepsis, and had not received broad-spectrum antibiotics in the previous 4 hours. Primary outcome was source pathogen, defined as confirmed bacterial source from sterile body fluid or confirmed viral source. Secondary outcome was sepsis severity, defined as maximum therapy required for shock reversal in the first 3 hospital days. We drew peripheral blood for ribonucleic acid isolation at the sepsis protocol activation, obtained gene expression measures with the GeneChip Human Gene 2.0 ST Array, and conducted differential expression analysis. RESULTS: We collected ribonucleic acid samples from a convenience sample of 122 children with suspected sepsis and 12 healthy controls. We compared the 66 children (54%) with confirmed bacterial or viral infection and found 558 differentially expressed genes, many related to interferon signaling or viral immunity. We did not find statistically significant gene expression differences in patients according to sepsis severity. CONCLUSION: The study demonstrates feasibility of evaluating gene expression profiling data in children evaluated for sepsis in the pediatric emergency department setting. Our results suggest that gene expression profiling may facilitate identification of source pathogen in children with suspected sepsis, which could ultimately lead to improved tailoring of sepsis treatment and antimicrobial stewardship.

RESUMO

OBJECTIVES: To compare timeliness of sepsis recognition and initial treatment in patients with and without high-risk comorbid conditions. METHODS: This was a retrospective cohort study of patients presenting to a pediatric emergency department (ED) who triggered a vital sign-based electronic sepsis alert resulting in bedside "huddle" assessment per institutional practice. A positive sepsis alert was defined as age-specific tachycardia or hypotension, concern for infection, and at least 1 of the following: abnormal capillary refill, abnormal mental status, or a high-risk condition. High-risk conditions were derived from the American Academy of Pediatrics sepsis alert tool. Patients with a positive alert underwent bedside huddle resulting in a decision regarding initiation of sepsis protocol. Placement on the protocol and time to initiation of protocol and individual therapies were compared for patients with and without high-risk conditions. RESULTS: During the 1-year study period, there were 1107 sepsis huddle alerts out of 96,427 ED visits. Of these, 713 (65%) had identified high-risk conditions, and 394 (35%) did not. Among patients with sepsis huddles, there was no difference in sepsis protocol initiation for patients with high-risk conditions compared with those without (24.8% vs 22.0%, P = 0.305). Between patients with high-risk conditions and those without, there were no differences in median time from triage to sepsis protocol activation, triage to initial intravenous antibiotic, triage to initial intravenous fluid therapy, or ED length of stay. CONCLUSIONS: Timeliness of care initiation was no different in high-risk patients with sepsis when using an electronic sepsis alert and protocolized sepsis care.

RESUMO

Objective: Evidence suggests using metered dose inhaler (MDI) to treat acute asthma in the Emergency Department reduces length of stay, though methods of implementation are lacking. We modified a treatment pathway to recommend use of MDI for mild-moderate asthma in a pediatric ED. Methods: A baseline review assessed discharged patients >2 years with an asthma diagnosis and non-emergent Emergency Severity Index triage assessment (3/4). Our multi-disciplinary team developed an intervention to increase MDI use instead of continuous albuterol (CA) using the following: (1) Redesign the asthma pathway and order set recommending MDI for ESI 3/4 patients. (2) Adding a conditional order for Respiratory Therapists to reassess and repeat MDI until patient reached mild assessment. The primary outcome was the percentage discharged within 3 hours, with a goal of a 10% increase compared to pre-intervention. Balancing measures included admission and revisit rates. Results: 7635 patients met eligibility before pathway change; 12,673 were seen in the subsequent 18 months. For target patients, the percentage discharged in <3 hours increased from 39% to 49%; reduction in median length of stay was 33 minutes. We identified special cause variation for reduction in CA use from 43% to 25%; Revisit rate and length of stay for higher-acuity patients did not change; overall asthma admissions decreased by 8%. Changes were sustained for 18 months. Conclusion: A change to an ED asthma pathway recommending MDI for mild-moderate asthma led to a rapid and sustained decrease in continuous albuterol use, length of stay, and admission rate.

RESUMO

OBJECTIVES: Most adolescent cases of pelvic inflammatory disease (PID) are diagnosed in the emergency department (ED). An important step to prevent PID-related morbidity among this high-risk population is to quantify prevalence and microbial patterns and identify testing and treatment gaps. METHODS: We performed a retrospective, cross-sectional study of all visits by adolescents to an urban children's ED with an International Classification of Diseases, Ninth Revision, diagnosis of PID in 2012. We used standard descriptive statistics to quantify PID diagnoses, sexually transmitted infections (STI) testing, and treatment. RESULTS: Pelvic inflammatory disease was diagnosed in more than 9% of women with a chief complaint of abdominal/pelvic pain. Most diagnosed cases underwent some STI testing, and 40% tested positive. Seventy percent of cases received antibiotics recommended by the Centers for Disease Control and Prevention. CONCLUSIONS: There is a high prevalence of PID among adolescents in the pediatric ED. Rates of STI testing and appropriate treatment reveal gaps in diagnosis and management, representing a lost opportunity for identification and treatment of PID/STIs among high-risk adolescents.

RESUMO

OBJECTIVE: To determine test characteristics of provider judgment for empiric antibiotic provision to patients undergoing testing for a sexually transmitted infection. STUDY DESIGN: We conducted a retrospective cross-sectional electronic health record review of all patients aged 13-19 years who had Neisseria gonorrhoeae (GC) and Chlamydia trachomatis (CT) testing sent from an urban, academic pediatric emergency department in 2012. We abstracted data, including patient demographics, chief complaint, sexually transmitted infection test results, and treatment. We calculated test characteristics comparing clinician judgment for presumptive treatment for a sexually transmitted infection with the reference standard of the actual results of testing for a sexually transmitted infection. RESULTS: Of 1223 patient visits meeting inclusion criteria, 284 (23.2%) had a positive GC and/or CT test result. Empiric treatment was provided in 615 encounters (50.3%). Provider judgment for presumptive treatment had an overall sensitivity of 67.6% (95% CI, 61.8-73.0) and a specificity of 55% (95% CI, 51.7-58.2) for accurate GC and/or CT detection. CONCLUSIONS: Many adolescents tested for GC and CT receive empiric treatment at the initial emergency department visit. Provider judgment may lack sufficient sensitivity and specificity for identifying infected patients, resulting in the potential for undertreatment of true disease, overtreatment of uninfected patients, or both.

RESUMO

STUDY OBJECTIVE: Recognition of pediatric sepsis is a key clinical challenge. We evaluate the performance of a sepsis recognition process including an electronic sepsis alert and bedside assessment in a pediatric emergency department (ED). METHODS: This was a cohort study with quality improvement intervention in a pediatric ED. Exposure was a positive electronic sepsis alert, defined as elevated pulse rate or hypotension, concern for infection, and at least one of the following: abnormal capillary refill, abnormal mental status, or high-risk condition. A positive electronic sepsis alert prompted team assessment or huddle to determine need for sepsis protocol. Clinicians could initiate team assessment or huddle according to clinical concern without positive electronic sepsis alert. Severe sepsis outcome defined as activation of the sepsis protocol in the ED or development of severe sepsis requiring ICU admission within 24 hours. RESULTS: There were 182,509 ED visits during the study period, with 86,037 before electronic sepsis alert implementation and 96,472 afterward, and 1,112 (1.2%) positive electronic sepsis alerts. Overall, 326 patients (0.3%) were treated for severe sepsis within 24 hours. Test characteristics of the electronic sepsis alert alone to detect severe sepsis were sensitivity 86.2% (95% confidence interval [CI] 82.0% to 89.5%), specificity 99.1% (95% CI 99.0% to 99.2%), positive predictive value 25.4% (95% CI 22.8% to 28.0%), and negative predictive value 100% (95% CI 99.9% to 100%). Inclusion of the clinician screen identified 43 additional electronic sepsis alert-negative children, with severe sepsis sensitivity 99.4% (95% CI 97.8% to 99.8%) and specificity 99.1% (95% CI 99.1% to 99.2%). Electronic sepsis alert implementation increased ED sepsis detection from 83% to 96%. CONCLUSION: Electronic sepsis alert for severe sepsis demonstrated good sensitivity and high specificity. Addition of clinician identification of electronic sepsis alert-negative patients further improved sensitivity. Implementation of the electronic sepsis alert was associated with improved recognition of severe sepsis.

RESUMO

OBJECTIVES: To determine whether treatment with a protocolized sepsis guideline in the emergency department was associated with a lower burden of organ dysfunction by hospital day 2 compared to nonprotocolized usual care in pediatric patients with severe sepsis. DESIGN: Retrospective cohort study. SETTING: Tertiary care children's hospital from January 1, 2012, to March 31, 2014. SUBJECTS: Patients older than 56 days old and younger than 18 years old with international consensus defined severe sepsis and who required PICU admission within 24 hours of emergency department arrival were included. MEASUREMENTS AND MAIN RESULTS: The exposure was the use of a protocolized emergency department sepsis guideline. The primary outcome was complete resolution of organ dysfunction by hospital day 2. One hundred eighty nine subjects were identified during the study period. Of these, 121 (64%) were treated with the protocolized emergency department guideline and 68 were not. There were no significant differences between the groups in age, sex, race, number of comorbid conditions, emergency department triage level, or organ dysfunction on arrival to the emergency department. Patients treated with protocolized emergency department care were more likely to be free of organ dysfunction on hospital day 2 after controlling for sex, comorbid condition, indwelling central venous catheter, Pediatric Index of Mortality-2 score, and timing of antibiotics and IV fluids (adjusted odds ratio, 4.2; 95% CI, 1.7-10.4). CONCLUSIONS: Use of a protocolized emergency department sepsis guideline was independently associated with resolution of organ dysfunction by hospital day 2 compared to nonprotocolized usual care. These data indicate that morbidity outcomes in children can be improved with the use of protocolized care.

RESUMO

OBJECTIVES: To evaluate accuracy of 2 established administrative methods of identifying children with sepsis using a medical record review reference standard. STUDY DESIGN: Multicenter retrospective study at 6 US children's hospitals. Subjects were children >60 days to <19 years of age and identified in 4 groups based on International Classification of Diseases, Ninth Revision, Clinical Modification codes: (1) severe sepsis/septic shock (sepsis codes); (2) infection plus organ dysfunction (combination codes); (3) subjects without codes for infection, organ dysfunction, or severe sepsis; and (4) infection but not severe sepsis or organ dysfunction. Combination codes were allowed, but not required within the sepsis codes group. We determined the presence of reference standard severe sepsis according to consensus criteria. Logistic regression was performed to determine whether addition of codes for sepsis therapies improved case identification. RESULTS: A total of 130 out of 432 subjects met reference SD of severe sepsis. Sepsis codes had sensitivity 73% (95% CI 70-86), specificity 92% (95% CI 87-95), and positive predictive value 79% (95% CI 70-86). Combination codes had sensitivity 15% (95% CI 9-22), specificity 71% (95% CI 65-76), and positive predictive value 18% (95% CI 11-27). Slight improvements in model characteristics were observed when codes for vasoactive medications and endotracheal intubation were added to sepsis codes (c-statistic 0.83 vs 0.87, P = .008). CONCLUSIONS: Sepsis specific International Classification of Diseases, Ninth Revision, Clinical Modification codes identify pediatric patients with severe sepsis in administrative data more accurately than a combination of codes for infection plus organ dysfunction.

RESUMO

BACKGROUND: Adolescents are at high risk for pelvic inflammatory disease (PID). Because accurate diagnosis of PID is difficult, and complications of untreated PID are significant, novel methods to improve diagnosis are essential. OBJECTIVES: To determine if patients with PID have unique RNA expression patterns compared to controls. METHODS: Peripheral blood was collected from adolescent females with PID in the emergency department, and from control patients in the operating room. RNA was isolated, and microarray analysis was performed. Initial analysis involved a training set of 18 patients (9 PID patients with either Neisseria gonorrhoeae or Chlamydia trachomatis infection and 9 control patients). Supervised and unsupervised cluster analyses were performed, followed by network analysis. The training set was used to classify a set of 15 additional PID patients and 2 controls. RESULTS: Supervised cluster analysis of the training set revealed 170 genes which were differentially expressed in PID patients versus controls. Network analysis indicated that several differentially expressed genes are involved in immune activation. Analysis of additional PID patients based on the training set findings revealed that patients with positive testing for Trichomonas vaginalis partitioned with the PID group, whereas patients with no organism identified partitioned with both groups. CONCLUSIONS: RNA sample collection from adolescents in the emergency department is feasible. Genes were identified which were differentially expressed in PID patients versus controls, many of which are involved in inflammation. Future studies should confirm the training set findings on a larger sample and may lead to improved accuracy of PID diagnosis.

RESUMO

OBJECTIVES: To evaluate clinician adherence to guidelines for documentation of sexual history and screening for sexually transmitted infection (STI)/HIV infection during routine adolescent well visits. Secondary objectives were to determine patient and clinician factors associated with sexual history documentation and STI/HIV testing. STUDY DESIGN: Retrospective, cross-sectional study of 1000 randomly selected 13- to 19-year-old routine well visits at all 29 pediatric primary care practices affiliated with a children's hospital. We evaluated frequency of documentation of sexual history and testing for gonorrhea (GC)/chlamydia (CT) and HIV testing. Multivariable logistic regression was performed to identify factors associated with documentation and testing. RESULTS: Of the 1000 patient visits reviewed, 212 (21.2%; 95% CI, 18.7-23.7) had a documented sexual history, of which 45 adolescents' (21.2%; 95% CI, 15.7-26.8) encounters were documented as being sexually active. Overall, 26 (2.6%; 95% CI, 1.6-3.6) patients were tested for GC/CT and 16 (1.6%; 95% CI, 0.8-2.4) were tested for HIV infection. In multivariable analyses, factors associated with sexual history documentation included older patient age, non-Hispanic black race/ethnicity, nonprivate insurance status, and care by female clinician. Factors associated with GC/CT testing included male gender, non-Hispanic black race/ethnicity, and nonprivate insurance. HIV testing was more likely to be performed on older adolescents, those of non-Hispanic black race/ethnicity, and those with nonprivate insurance. CONCLUSIONS: Pediatric primary care clinicians infrequently document sexual histories and perform STI and HIV testing on adolescent patients. Future studies should investigate provider beliefs, clinical decision-making principles, and perceived barriers to improve the sexual health care of adolescents and evaluate interventions to increase rates of adolescent sexual health screening.

RESUMO

OBJECTIVES: To compare the prevalence, resource utilization, and mortality for pediatric severe sepsis identified using two established identification strategies. DESIGN: Observational cohort study from 2004 to 2012. SETTING: Forty-four pediatric hospitals contributing data to the Pediatric Health Information Systems database. PATIENTS: Children 18 years old or younger. MEASUREMENTS AND MAIN RESULTS: We identified patients with severe sepsis or septic shock by using two International Classification of Diseases, 9th edition, Clinical Modification-based coding strategies: 1) combinations of International Classification of Diseases, 9th edition, Clinical Modification codes for infection plus organ dysfunction (combination code cohort); 2) International Classification of Diseases, 9th edition, Clinical Modification codes for severe sepsis and septic shock (sepsis code cohort). Outcomes included prevalence of severe sepsis, as well as hospital and ICU length of stay, and mortality. Outcomes were compared between the two cohorts examining aggregate differences over the study period and trends over time. The combination code cohort identified 176,124 hospitalizations (3.1% of all hospitalizations), whereas the sepsis code cohort identified 25,236 hospitalizations (0.45%), a seven-fold difference. Between 2004 and 2012, the prevalence of sepsis increased from 3.7% to 4.4% using the combination code cohort and from 0.4% to 0.7% using the sepsis code cohort (p < 0.001 for trend in each cohort). Length of stay (hospital and ICU) and costs decreased in both cohorts over the study period (p < 0.001). Overall, hospital mortality was higher in the sepsis code cohort than the combination code cohort (21.2% [95% CI, 20.7-21.8] vs 8.2% [95% CI, 8.0-8.3]). Over the 9-year study period, there was an absolute reduction in mortality of 10.9% (p < 0.001) in the sepsis code cohort and 3.8% (p < 0.001) in the combination code cohort. CONCLUSIONS: Prevalence of pediatric severe sepsis increased in the studied U.S. children's hospitals over the past 9 years, whereas resource utilization and mortality decreased. Epidemiologic estimates of pediatric severe sepsis varied up to seven-fold depending on the strategy used for case ascertainment.

RESUMO

Experiences of distress and challenging emotions in response to the climate crisis are increasingly common, particularly among young adults. These experiences can include challenging emotions caused by the harmful environmental impacts of conventional food systems, as their contributions to greenhouse gas emissions have become more widely known. While recent studies have examined various experiences of climate distress, the interaction between climate distress and food practice remains poorly understood. In this research, we turn to this intersection by examining the experiences of climate distress of young adults who have alternative food practices, and the interaction between their climate distress and their alternative food practices. Guided by an exploratory, single case study research approach, this research draws from 20 semi-structured interviews conducted with young adults located in urban centres in the Southeastern Prairie Region of Canada. Thematic analysis of the findings reveals that participants experience a variety of climate emotions and a personal responsibility to act in response to the climate crisis. The findings suggest that because of their ability to facilitate a meaningful and practical environmental impact, alternative food practices represent significant climate actions and may be pathways to facilitate coping or managing climate distress among young adults. Results demonstrate the psychological impacts of the climate crisis on young adults, highlighting the need for action on climate change and climate distress. Increasing the accessibility of alternative food practices may support young adults in coping with challenging climate emotions.
