ABSTRACT
BACKGROUND: We have previously reported a simple correction method for estimating pleural pressure (Ppl) using central venous pressure (CVP). However, it remains unclear whether this method is applicable to patients with varying levels of intravascular volumes and/or chest wall compliance. This study aimed to investigate the accuracy of our method under different conditions of intravascular volume and chest wall compliance. RESULTS: Ten anesthetized and paralyzed pigs (43.2 ± 1.8 kg) were mechanically ventilated and subjected to lung injury by saline lung lavage. Each pig was subjected to three different intravascular volumes and two different intraabdominal pressures. For each condition, the changes in the esophageal pressure (ΔPes) and the estimated ΔPpl using ΔCVP (cΔCVP-derived ΔPpl) were compared to the directly measured change in pleural pressure (Δd-Ppl), which was the gold standard estimate in this study. The cΔCVP-derived ΔPpl was calculated as κ × ΔCVP, where "κ" was the ratio of the change in airway pressure to the change in CVP during the occlusion test. The means and standard deviations of the Δd-Ppl, ΔPes, and cΔCVP-derived ΔPpl for all pigs under all conditions were 7.6 ± 4.5, 7.2 ± 3.6, and 8.0 ± 4.8 cmH2O, respectively. The repeated measures correlations showed that both the ΔPes and cΔCVP-derived ΔPpl showed a strong correlation with the Δd-Ppl (ΔPes: r = 0.95, p < 0.0001; cΔCVP-derived ΔPpl: r = 0.97, p < 0.0001, respectively). In the Bland-Altman analysis to test the performance of the cΔCVP-derived ΔPpl to predict the Δd-Ppl, the ΔPes and cΔCVP-derived ΔPpl showed almost the same bias and precision (ΔPes: 0.5 and 1.7 cmH2O; cΔCVP-derived ΔPpl: - 0.3 and 1.9 cmH2O, respectively). No significant difference was found in the bias and precision depending on the intravascular volume and intraabdominal pressure in both comparisons between the ΔPes and Δd-Ppl, and cΔCVP-derived ΔPpl and Δd-Ppl. CONCLUSIONS: The CVP method can estimate the ΔPpl with reasonable accuracy, similar to Pes measurement. The accuracy was not affected by the intravascular volume or chest wall compliance.
ABSTRACT
Quality improvement in clinical laboratories is crucial to ensure accurate and reliable test results. With increasing awareness of the potential adverse effects of errors in laboratory practice on patient outcomes, the need for continual improvement of laboratory services cannot be overemphasized. A literature search was conducted on PubMed and a web of science core collection between October and February 2021 to evaluate the scientific literature quality of clinical laboratory quality improvement; only peer-reviewed articles written in English that met quality improvement criteria were included. A structured template was used to extract data, and the papers were rated on a scale of 0-16 using the Quality Improvement Minimum Quality Criteria Set (QI-MQCS). Out of 776 studies, 726 were evaluated for clinical laboratory literature quality analysis. Studies were analyzed according to the quality improvement and control methods and interventions, such as training, education, task force, and observation. Results showed that the average score of QI-MQCS for quality improvement papers from 1981-2000 was 2.5, while from 2001-2020, it was 6.8, indicating continuous high-quality improvement in the clinical laboratory sector. However, there is still room to establish a proper system to judge the quality of clinical laboratory literature and improve accreditation programs within the sector.
ABSTRACT
Evidence for outcome improvement is limited for using 5% human albumin solution (5% albumin) in pediatric intensive care units (PICUs). However, 5% albumin was injudiciously used in our PICU. Therefore, we aimed to decrease 5% albumin use in pediatric patients (17 years old or younger) in the PICU by 50% in 12 months to improve health care efficiency. Methods: We plotted the mean 5% albumin volume used per PICU admission monthly on statistical process control charts through 3 study periods: baseline period before intervention (July 2019-June 2020), phase 1 (August 2020-April 2021), and phase 2 (May 2021-April 2022). With intervention 1, education, feedback, and an alert sign on 5% albumin stocks began in July 2020. This intervention continued until May 2021, when we executed intervention 2, removing 5% albumin from the PICU inventory. We also examined the lengths of invasive mechanical ventilation and PICU stay as balancing measures across the 3 periods. Results: Mean 5% albumin consumption per PICU admission decreased significantly from 48.1 to 22.4 mL after intervention 1 and 8.3 mL after intervention 2, with the intervention effects persisting for 12 months. Costs associated with 5% albumin per PICU admission significantly decreased by 82%. In terms of patient characteristics and balancing measures, the 3 periods were not different. Conclusions: Stepwise quality improvement interventions, including the system change with the elimination of the 5% albumin inventory from the PICU, were effective in reducing 5% albumin use in the PICU with sustained reduction.
ABSTRACT
OBJECTIVES: Machine learning-based prediction of hospital admissions may have the potential to optimize patient disposition and improve clinical outcomes by minimizing both undertriage and overtriage in crowded emergency care. We developed and validated the predictive abilities of machine learning-based predictions of hospital admissions in a pediatric emergency care center. METHODS: A prognostic study was performed using retrospectively collected data of children younger than 16 years who visited a single pediatric emergency care center in Osaka, Japan, between August 1, 2016, and October 15, 2019. Generally, the center treated walk-in children and did not treat trauma injuries. The main outcome was hospital admission as determined by the physician. The 83 potential predictors available at presentation were selected from the following categories: demographic characteristics, triage level, physiological parameters, and symptoms. To identify predictive abilities for hospital admission, maximize the area under the precision-recall curve, and address imbalanced outcome classes, we developed the following models for the preperiod training cohort (67% of the samples) and also used them in the 1-year postperiod validation cohort (33% of the samples): (1) logistic regression, (2) support vector machine, (3) random forest, and (4) extreme gradient boosting. RESULTS: Among 88,283 children who were enrolled, the median age was 3.9 years, with 47,931 (54.3%) boys and 1985 (2.2%) requiring hospital admission. Among the models, extreme gradient boosting achieved the highest predictive abilities (eg, area under the precision-recall curve, 0.26; 95% confidence interval, 0.25-0.27; area under the receiver operating characteristic curve, 0.86; 95% confidence interval, 0.84-0.88; sensitivity, 0.77; and specificity, 0.82). With an optimal threshold, the positive and negative likelihood ratios were 4.22, and 0.28, respectively. CONCLUSIONS: Machine learning-based prediction of hospital admissions may support physicians' decision-making for hospital admissions. However, further improvements are required before implementing these models in real clinical settings.

BACKGROUND: The Child Hospital Consumer Assessment of Healthcare Providers and Systems Survey (Child HCAHPS) assesses the experiences of pediatric patients and their parents or guardians with inpatient care. This study aimed to develop a Japanese version of the Child HCAHPS and to examine its validity and reliability. METHODS: A Japanese version draft of the Child HCAHPS was produced in a conceptually equivalent and culturally appropriate manner. Using the draft Japanese version, the survey was administered using a push-to-web method to eligible parents/guardians of children (aged 0-17 years) discharged from a tertiary children's hospital in Osaka, Japan in December 2021 through March 2022. Construct validity and internal consistency reliability were tested. RESULTS: Of 1300 eligible candidates to whom survey invitations were mailed, 460 returned complete surveys (response rate 35%). The validity of a composite "Involving teens in their care" remained unproven. However, with the remaining composites, confirmatory factor analysis indicated fair goodness of fit of the same factor structure as that of the original Child HCAHPS (the comparative fit index = 0.92, Tucker-Lewis index = 0.90, and root mean square error of approximation = 0.052). The Cronbach coefficient was close to or above 0.7 for most of the items, indicating good reliability. CONCLUSIONS: The Japanese Child HCAHPS demonstrated acceptable psychometric properties for assessing patient and family experiences in a Japanese tertiary children's hospital. However, several items and composites with suboptimal properties warrant further validation in future multicenter surveys.

OBJECTIVES: To compare the pathogen identification rate and use of antibiotics before and after the implementation of multiplex polymerase chain reaction testing in children with respiratory infections in a PICU. DESIGN: Single-center, pre-post study. SETTING: PICU of Osaka Women's and Children's Hospital, Osaka, Japan. PATIENTS: Consecutive children with respiratory infections who were admitted to the PICU between December 2017 and November 2018 (premultiplex polymerase chain reaction period) and between March 2019 and February 2020 (postmultiplex polymerase chain reaction period). INTERVENTIONS: Conventional rapid antigen tests and bacterial culture tests were performed throughout the study period. Multiplex polymerase chain reaction testing using the FilmArray respiratory panel (BioFire Diagnostics, Salt Lake City, UT) was conducted to detect 17 viruses and three bacterial pathogens. During the postmultiplex polymerase chain reaction period, we did not recommend prescribing antibiotics for stable children, depending on the virus species and laboratory test results. MEASUREMENTS AND MAIN RESULTS: Ninety-six and 85 children were enrolled during the pre- and postmultiplex polymerase chain reaction periods, respectively. Rapid antigen tests identified pathogens in 22% of the children (n = 21) during the premultiplex polymerase chain reaction period, whereas rapid antigen tests and/or multiplex polymerase chain reaction testing identified pathogens in 67% of the children (n = 57) during the postmultiplex polymerase chain reaction period (p < 0.001). The most commonly identified pathogen using multiplex polymerase chain reaction testing was human rhino/enterovirus. Bacterial pathogens were identified in 50% of the children (n = 48) and 60% of the children (n = 51) during the pre- and postmultiplex polymerase chain reaction periods (p = 0.18). There were no differences in antibiotic use (84% vs 75%; p = 0.14), broad-spectrum antibiotic use (33% vs 34%; p = 0.91), or the duration of antibiotic use within 14 days of admission (6.0 vs 7.0 d; p = 0.45) between the pre- and postmultiplex polymerase chain reaction periods. CONCLUSIONS: Although the pathogen identification rate, especially for viral pathogens, increased using multiplex polymerase chain reaction testing, antibiotic use did not reduce in children with respiratory infections in the PICU. Definitive identification of bacterial pathogens and implementation of evidence-based antimicrobial stewardship programs employing multiplex polymerase chain reaction testing are warranted.

OBJECTIVES: To synthesize the literature describing quality improvement in PICUs and to appraise the quality of extant research. DATA SOURCES: We searched the PubMed, Cumulative Index to Nursing and Allied Health Literature, and the Cochrane Central Register of Controlled Trials databases between May and June 2020. STUDY SELECTION: Peer-reviewed articles in English that report quality improvement interventions in PICUs were included. Titles and abstracts were screened, and articles were reviewed to determine whether they met quality improvement criteria. DATA EXTRACTION: Data were abstracted using a structured template. The quality of the included articles was assessed using the Quality Improvement Minimum Quality Criteria Set and scored on a scale of 0-16. DATA SYNTHESIS: Of the 2,449 articles identified, 158 were included in the analysis. The most common targets of quality improvement interventions were healthcare-associated infections (n = 17, 10.8%), handoffs (n = 15, 9.5%), rounds (n = 13, 8.2%), sedation/pain/delirium (n = 13, 8.2%), medication safety (n = 11, 7.0%), and unplanned extubation (n = 9, 5.7%). Of the six domains of healthcare quality described by the Institute of Medicine, patient-centeredness and timeliness were infrequently addressed, and none of the studies addressed equity. The median quality score based on the Quality Improvement Minimum Quality Criteria Set was 11.0 (25-75th interquartile range, 9.0-13.0). Although the quantity and quality of articles have been increasing, only 17% of the studies were deemed "high quality," having a score between 14 and 16. Only eight articles (5%) cited Standards for QUality Improvement Reporting Excellence guidelines for reporting quality improvement works. CONCLUSIONS: The number of publications, including high-quality publications, on quality improvement interventions in PICUs has been increasing. However, low-quality articles continue to be published, even in recent years. Therefore, there is room for improvement in the quality of reporting.

BACKGROUND: It is important to evaluate the size of respiratory effort to prevent patient self-inflicted lung injury and ventilator-induced diaphragmatic dysfunction. Esophageal pressure (Pes) measurement is the gold standard for estimating respiratory effort, but it is complicated by technical issues. We previously reported that a change in pleural pressure (ΔPpl) could be estimated without measuring Pes using change in CVP (ΔCVP) that has been adjusted with a simple correction among mechanically ventilated, paralyzed pediatric patients. This study aimed to determine whether our method can be used to estimate ΔPpl in assisted and unassisted spontaneous breathing patients during mechanical ventilation. METHODS: The study included hemodynamically stable children (aged <18 years) who were mechanically ventilated, had spontaneous breathing, and had a central venous catheter and esophageal balloon catheter in place. We measured the change in Pes (ΔPes), ΔCVP, and ΔPpl that was calculated using a corrected ΔCVP (cΔCVP-derived ΔPpl) under three pressure support levels (10, 5, and 0 cmH2O). The cΔCVP-derived ΔPpl value was calculated as follows: cΔCVP-derived ΔPpl = k × ΔCVP, where k was the ratio of the change in airway pressure (ΔPaw) to the ΔCVP during airway occlusion test. RESULTS: Of the 14 patients enrolled in the study, 6 were excluded because correct positioning of the esophageal balloon could not be confirmed, leaving eight patients for analysis (mean age, 4.8 months). Three variables that reflected ΔPpl (ΔPes, ΔCVP, and cΔCVP-derived ΔPpl) were measured and yielded the following results: -6.7 ± 4.8, - -2.6 ± 1.4, and - -7.3 ± 4.5 cmH2O, respectively. The repeated measures correlation between cΔCVP-derived ΔPpl and ΔPes showed that cΔCVP-derived ΔPpl had good correlation with ΔPes (r = 0.84, p< 0.0001). CONCLUSIONS: ΔPpl can be estimated reasonably accurately by ΔCVP using our method in assisted and unassisted spontaneous breathing children during mechanical ventilation.

BACKGROUND: Acute encephalitis/encephalopathy (AE) associated with viral and other pathogens leads to neurological sequelae and mortality. Knowing the prognostic factors is therefore important for immediate interventions. We examined early-phase unfavorable prognostic factors among children with AE using a nationwide database. METHODS: We performed a retrospective cohort study using the Diagnosis Procedure Combination database, which includes approximately half of acute-care inpatients across Japan. We enrolled children agedâ ≤â 18 years who were hospitalized for AE and discharged from April 2010 to March 2018. The composite unfavorable outcome included the following at discharge: in-hospital death, tracheostomy, enteral tube feeding, and physical rehabilitation. Unfavorable prognostic factors were assessed using a multivariable Poisson regression model including patient characteristics, associated pathogens, and interventions within 2 days of admission adjusting for within-hospital clustering. RESULTS: This study included 9386 children with AE (median age, 3 years). A total of 241 (2.6%) in-hospital deaths occurred, and 2027 (21.6%) patients had the composite unfavorable outcome. Significant unfavorable prognostic factors were age 12-18 years, congenital anomalies, epilepsy, and Japan Coma Scale score of 100-300 at admission (ie, worse levels of consciousness). In contrast, herpes simplex virus infection and influenza virus infection were associated with favorable outcomes. CONCLUSIONS: We identified early-phase (within 2 days of admission) unfavorable prognostic factors among children with AE. These findings will help identify patients who may benefit from early aggressive therapeutic interventions.

OBJECTIVES: We aimed to identify the occurrence and risk factors for unplanned catheter removal due to catheter-associated complications and the effects on catheter survival probability in a PICU. DESIGN: Retrospective, single-center, observational study of cases involving conventional central venous catheters or peripherally inserted central venous catheters. SETTING: The PICU of a tertiary children's hospital. PATIENTS: Consecutive PICU patients with central venous catheters between April 2016 and February 2019. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We identified unplanned catheter removals that were related to central line-associated bloodstream infection, thrombosis, and mechanical complications. During the study period, 582 central venous catheters and 474 peripherally inserted central venous catheters were identified. The median durations of catheter placement were 4.0 days for central venous catheters and 13.0 days for peripherally inserted central venous catheters (p < 0.001), and unplanned catheter removals due to catheter-associated complications were in 52 (8.9%) central venous catheter cases and 132 (27.8%) peripherally inserted central venous catheter cases (p < 0.001) (15.0 and 16.0 per 1,000 catheter-days, respectively [p = 0.75]). Unplanned catheter removal was associated with a peripheral catheter tip position among both central venous catheters and peripherally inserted central venous catheters (p < 0.001 and p = 0.001), and it was associated with surgical patient status among peripherally inserted central venous catheters (p = 0.009). In contrast, the use of ultrasound-guided insertion was associated with a lower occurrence of unplanned catheter removal among peripherally inserted central venous catheters (p = 0.01). With regard to catheter survival probability, there was no significant difference between central venous catheters and peripherally inserted central venous catheters (p = 0.23). However, peripherally inserted central venous catheters had a lower occurrence of central line-associated bloodstream infection than central venous catheters (p = 0.03), whereas there was no significant difference in the rates of thrombosis (p = 0.29) and mechanical complications (p = 0.84) between central venous catheters and peripherally inserted central venous catheters. CONCLUSIONS: In a PICU, peripherally inserted central venous catheters had lower occurrence of central line-associated bloodstream infection than central venous catheters; however, similar catheter survival probabilities were observed between both catheters. A central catheter tip position for both catheters and ultrasound-guided insertion for peripherally inserted central venous catheters may help limit unplanned catheter removal due to catheter-associated complications.

BACKGROUND: Disseminated intravascular coagulation (DIC) is a common complication in sepsis because of crosstalk between the immune system and the coagulation system. Several anticoagulant agents have been tested in an attempt to improve the survival of patients with sepsis and sepsis-induced DIC. Here, we discuss the rationale against using anticoagulation therapy in septic DIC. MAIN BODY OF THE ABSTRACT: Coagulopathy and DIC are associated with increased mortality in sepsis. Several anticoagulant agents have been tested in an attempt to improve the survival of patients with sepsis and sepsis-induced DIC, but have proven largely ineffective. This is because of two major factors. First, the coagulation system is complex and closely related to the immune system. When we manipulate one of the factors involved in these systems, we may disturb the delicate homeostasis between them. A second factor may be failure to identify patients who will benefit from anticoagulation therapy. This may be attributed partly to the fact that there is no gold standard for the diagnosis of DIC, and there are consequently several diagnostic criteria, none of which are specifically designed for sepsis-induced DIC. Application of precision medicine, of the kind currently being applied in other intensive care fields, may be the key to overcoming these challenges. Until we know the precise target population, we should not use anticoagulation therapy in sepsis-induced DIC outside a research setting. SHORT CONCLUSION: There is no strong evidence to support the effectiveness of routine anticoagulation therapy in sepsis-induced DIC, and it should not be used clinically until more is known regarding the population of patients who may benefit from it.
ABSTRACT
The objective of the study is to develop a correction method for estimating the change in pleural pressure (ΔPpl) and plateau transpulmonary pressure (PL) by using the change in central venous pressure (ΔCVP). Seven children (aged < 15 years) with acute respiratory failure (PaO2/FIO2 < 300 mmHg), who were paralyzed and mechanically ventilated with a PEEP of < 10 cmH2O and had central venous catheters and esophageal balloon catheters placed for clinical purposes, were enrolled prospectively. We compared change in esophageal pressure (ΔPes), ΔCVP, and ΔPpl calculated using a corrected ΔCVP (cΔCVP-derived ΔPpl). cΔCVP-derived ΔPpl was calculated as κ × ΔCVP, where κ was the ratio of the change in airway pressure (ΔPaw) to ΔCVP during the occlusion test. cΔCVP-derived ΔPpl correlated better than ΔCVP with ΔPes (R2 = 0.48, p = 0.08 vs. R2 = 0.14, p = 0.4) with lesser bias and precision in Bland-Altman analysis. The plateau PL calculated using the cΔCVP-derived ΔPpl (17.6 ± 2.6 cmH2O) correlated well with the ΔPes-derived plateau PL (18.1 ± 2.3 cmH2O) (R2 = 0.90, p = 0.001). Our correction method can estimate ΔPpl and plateau PL from ΔCVP with a reasonable accuracy in paralyzed and mechanically ventilated pediatric patients with respiratory failure.

OBJECTIVE: Although a few studies have reported the efficacy of ultrasound-guided peripherally inserted central catheter placement for pediatric patients, the procedure still is challenging. Ultrasound-guided dynamic needle tip positioning technique is useful for vascular catheterization. There have been no reports on using dynamic needle tip positioning for peripherally inserted central catheter placement. The authors assessed the rate of successful peripherally inserted central catheter placement with dynamic needle tip positioning. DESIGN: Case series. SETTING: Single tertiary institution. PARTICIPANTS: Forty patients <5 years old who were admitted to the pediatric intensive care unit after cardiac surgeries and required peripherally inserted central catheter placement. INTERVENTIONS: Peripherally inserted central catheter placement was performed under ultrasound guidance with dynamic needle tip positioning. The authors recorded the first attempt and overall success rates of peripherally inserted central catheter and outer cannula placement, time needed for outer cannula and peripherally inserted central catheter placement, and number of attempts. MEASUREMENTS AND MAIN RESULTS: The first attempt and overall success rates of peripherally inserted central catheter placement were 85% (nâ¯=â¯34) and 97.5% (nâ¯=â¯39), respectively. The first attempt and overall success rates of outer cannula placement were 87.5% (nâ¯=â¯35) and 100% (nâ¯=â¯40), respectively. Time needed for outer cannula placement was 59.5 (interquartile range 40.5-80.5) seconds and for peripherally inserted central catheter placement was 112.5 (interquartile range 91.5-159.5) seconds. The number of attempts was 1 (interquartile range 1-1 [range 1-5]). CONCLUSIONS: In pediatric patients, ultrasound-guided peripherally inserted central catheter placement using dynamic needle tip positioning attained a high success rate.

BACKGROUND: Unscheduled readmission to a paediatric intensive care unit can lead to unfavourable patient outcomes. Therefore, determining the incidence and risk factors is important. Previous studies on such readmissions have only focused on the first 48 hours after discharge and described the relative risk factors as unmodifiable. AIM: To identify the incidence and risk factors of unscheduled readmission to a paediatric intensive care unit within 7 days of discharge. DESIGN: This was a retrospective observational study. METHODS: Our study population comprised consecutive patients admitted to the paediatric intensive care unit of our tertiary hospital in Japan in 2012 to 2016. We determined the incidence of unscheduled readmission to the unit within 7 days of discharge and identified potential risk factors using multivariable logistic regression analysis. RESULTS: Among the 2432 admissions (1472 patients), 60 admissions (2.5%, 44 patients) were followed by ≥1 unscheduled readmission. The median time to readmission was 3.5 days. The most common causes for readmission were respiratory issues and cardiovascular symptoms. The significant risk factors for readmission within 7 days of discharge were unscheduled initial admission (odds ratio [OR]: 3.02; 95% confidence interval [CI:] 1.45-6.31), admission from a general ward (OR: 5.13; 95% CI: 1.75-15.0), and withdrawal syndrome during the initial stay (OR: 3.95; 95% CI: 1.53-10.2). CONCLUSIONS: The incidence of unscheduled readmission within 7 days was not high (2.5%), and one of the three identified risk factors for readmissions (withdrawal syndrome) is potentially modifiable. RELEVANCE TO CLINICAL PRACTICE: Appropriate treatment of withdrawal syndrome may reduce readmissions and improve patient outcomes. Although unscheduled initial admission and admission from general ward are not modifiable risk factors, careful discharge judgement and follow up after discharge from paediatric intensive care units for high-risk patients may be beneficial.
