PELOD-2: an update of the PEdiatric logistic organ dysfunction score

Crit Care Med. 2013 Jul;41(7):1761-73. doi: 10.1097/CCM.0b013e31828a2bbd.

ABSTRACT

OBJECTIVE: Multiple organ dysfunction syndrome is the main cause of death in adult ICUs and in PICUs. The PEdiatric Logistic Organ Dysfunction score developed in 1999 was primarily designed to describe the severity of organ dysfunction. This study was undertaken to update and improve the PEdiatric Logistic Organ Dysfunction score, using a larger and more recent dataset.

DESIGN: Prospective multicenter cohort study.

SETTING: Nine multidisciplinary, tertiary-care PICUs of university-affiliated hospitals in France and Belgium.

PATIENTS: All consecutive children admitted to these PICUs (June 2006-October 2007).

INTERVENTION: None.

MEASUREMENTS AND MAIN RESULTS: We collected data on variables considered for the PEdiatric Logistic Organ Dysfunction-2 score during PICU stay up to eight time points: days 1, 2, 5, 8, 12, 16, and 18, plus PICU discharge. For each variable considered for the PEdiatric Logistic Organ Dysfunction-2 score, the most abnormal value observed during time points was collected. The outcome was vital status at PICU discharge. Identification of the best variable cutoffs was performed using bivariate analyses. The PEdiatric Logistic Organ Dysfunction-2 score was developed by multivariable logistic regressions and bootstrap process. We used areas under the receiver-operating characteristic curve to evaluate discrimination and Hosmer-Lemeshow goodness-of-fit tests to evaluate calibration. We enrolled 3,671 consecutive patients (median age, 15.5 mo; interquartile range, 2.2-70.7). Mortality rate was 6.0% (222 deaths). The PEdiatric Logistic Organ Dysfunction-2 score includes ten variables corresponding to five organ dysfunctions. Discrimination (areas under the receiver-operating characteristic curve = 0.934) and calibration (chi-square test for goodness-of-fit = 9.31, p = 0.317) of the PEdiatric Logistic Organ Dysfunction-2 score were good.

CONCLUSION: We developed and validated the PEdiatric Logistic Organ Dysfunction-2 score, which allows assessment of the severity of cases of multiple organ dysfunction syndrome in the PICU with a continuous scale. The PEdiatric Logistic Organ Dysfunction-2 score now includes mean arterial pressure and lactatemia in the cardiovascular dysfunction and does not include hepatic dysfunction. The score will be in the public domain, which means that it can be freely used in clinical trials.

Management by the intensivist of gastrointestinal bleeding in adults and children

Ann Intensive Care. 2012 Nov 9;2(1):46. doi: 10.1186/2110-5820-2-46.

ABSTRACT

Intensivists are regularly confronted with the question of gastrointestinal bleeding. To date, the latest international recommendations regarding prevention and treatment for gastrointestinal bleeding lack a specific approach to the critically ill patients. We present recommendations for management by the intensivist of gastrointestinal bleeding in adults and children, developed with the GRADE system by an experts group of the French-Language Society of Intensive Care (Société de Réanimation de Langue Française (SRLF), with the participation of the French Language Group of Paediatric Intensive Care and Emergencies (GFRUP), the French Society of Emergency Medicine (SFMU), the French Society of Gastroenterology (SNFGE), and the French Society of Digestive Endoscopy (SFED). The recommendations cover five fields of application: management of gastrointestinal bleeding before endoscopic diagnosis, treatment of upper gastrointestinal bleeding unrelated to portal hypertension, treatment of upper gastrointestinal bleeding related to portal hypertension, management of presumed lower gastrointestinal bleeding, and prevention of upper gastrointestinal bleeding in intensive care.

Management of thrombocytopenia in the ICU (pregnancy excluded)

Ann Intensive Care. 2012 Aug 28;2(1):42. doi: 10.1186/2110-5820-2-42.

ABSTRACT

Thrombocytopenia is a very frequent disorder in the intensive care unit. Many etiologies should be searched, and therapeutic approaches differ according to these different causes. However, no guideline exists regarding optimum practices for these situations in critically ill patients. We present recommendations for the management of thrombocytopenia in intensive care unit, excluding pregnancy, developed by an expert group of the French-Language Society of Intensive Care (Société de Réanimation de Langue Française (SRLF), the French Language Group of Paediatric Intensive Care and Emergencies (GFRUP) and of the Haemostasis and Thrombosis Study Group (GEHT) of the French Society of Haematology (SFH). The recommendations cover six fields of application: definition, epidemiology, and prognosis; diagnostic approach; therapeutic aspects; thrombocytopenia and sepsis; iatrogenic thrombocytopenia, with a special focus on heparin-induced thrombocytopenia; and thrombotic microangiopathy.

International comparison of the performance of the paediatric index of mortality (PIM) 2 score in two national data sets

Intensive Care Med. 2012 Aug;38(8):1372-80. doi: 10.1007/s00134-012-2580-6. Epub 2012 May 9.

ABSTRACT

OBJECTIVES: To test the performance of PIM2 in French-speaking (FS) paediatric intensive care units (PICUs) and its relative performance when recalibrated using data from FS and Great Britain (GB) PICUs of different size.

METHODS: Consecutive admissions to 15 FS (n = 5,602) and 31 GB PICUs (n = 20,693) from June 2006 to October 2007 were included. The recalibrated PIM2 were applied to PICUs of different size within the FS and GB PICUs and between the two groups. PICU size was defined using number of admissions/month. Discrimination and calibration were evaluated using the area under the ROC curve (AUC) and the goodness-of-fit test, respectively. Logistic regression, funnel plots and standardized W scores were performed in the two groups and between different PICU sizes.

RESULTS: In FS PICUs, the original PIM2 had good discrimination (AUC = 0.85) and moderate calibration (p = 0.07). The recalibrated PIM2 scores had good calibration in FS (p = 0.33) and moderate calibration in GB (p = 0.06). Calibration was poor when the recalibrated FS PIM2 was applied to GB (p = 0.02) but good when the GB recalibration was applied to the FS (p = 0.36). Using the original PIM2 coefficients, calibration was poor in large units in both groups but improved following recalibration. There were no effects of PICU size on risk-adjusted mortality in GB and a significant effect in the FS PICUs with a minimum risk-adjusted mortality at about 35 admissions/month.

CONCLUSION: The PIM2 score was valid in the FS population. The recalibration based on GB data could be applied to FS PICUs. Such recalibration may facilitate comparisons between countries.

Prevalence of questioning regarding life-sustaining treatment and time utilisation by forgoing treatment in francophone PICUs

Intensive Care Med. 2011 Oct;37(10):1648-55. doi: 10.1007/s00134-011-2320-3. Epub 2011 Aug 16.

ABSTRACT

PURPOSE: Our goal is to assess the prevalence of questioning about the appropriateness of initiating or maintaining life-sustaining treatments (LST) in French-speaking paediatric intensive care units (PICUs) and to evaluate time utilisation related to decision-making processes (DMP).

METHODS: 18-month, multicentre, prospective, descriptive, observational study in 15 French-speaking PICUs.

RESULTS: Among the 5,602 children admitted, 410 died (7.3%), including 175 after forgoing LST (42.7% of deaths). LST was questioned in 308 children (5.5%) with a prevalence of 13.3 per 100 patient-days. More than 30% of children survived despite the appropriateness of LST being questioned (23% despite a decision to forgo treatment). Median caregiver time spent on making and presenting the decisions was 11 h per child.

CONCLUSIONS: In this study, on any given day in each 10-bed PICU, there was more than one child for whom a DMP was underway. Of children, 23% survived despite a decision to forgo LST being made, which underlines the need to elaborate a care plan for these children. Also, DMP represented a large amount of staff time that is undervalued but necessary to ensure optimal palliative practice in PICU.

Effectiveness of multifunction paediatric short-stay units: a French multicentre study

Acta Paediatr. 2011 Nov;100(11):e227-33. doi: 10.1111/j.1651-2227.2011.02356.x. Epub 2011 Jun 11.

ABSTRACT

AIM: To describe the characteristics of the activities of multifunction paediatric 'short-stay units' (SSU) including observation unit (OU), medical assessment and planning unit (MAPU) and holding unit (HU), to evaluate their effectiveness and to explore predictors of inappropriate admissions for OU patients.

METHODS: Admissions to nine French paediatric SSUs were analysed. The main outcome measures were SSU length of stay with associated outcome for all patients and appropriate admission rate for OU patients.

RESULTS: Of 1084 patients included in the study, 66% were OU patients (n = 718), 21% MAPU patients (n = 225) and 13% HU patients (n = 141). The OU patients constituted the majority of the SSU admissions. The appropriate OU admission rates ranged from 52% to 86%. Head trauma and seizure were the conditions with the highest appropriate OU admission rates (82%). Age <1 year, and need for IV fluids or medications, CT-Scan or MRI and cardiorespiratory monitoring were associated with an increased risk of inappropriate OU admission. Eighteen per cent of the MAPU patients and 5% of the HU patients were discharged home within 24 h.

CONCLUSION: By providing extended and easily available facilities for diagnostics and early treatment for a wide range of sick children, the French paediatric SSU is an effective model for 'observation medicine' in emergency department-managed units. The experience and principles may be applicable to similar units in other health care systems.

Children with chronic conditions in pediatric intensive care units located in predominantly French-speaking regions: Prevalence and implications on rehabilitation care need and utilization

Crit Care Med. 2009 Apr;37(4):1456-62. doi: 10.1097/CCM.0b013e31819cef0c.

ABSTRACT

OBJECTIVE: To estimate the prevalence of chronic conditions and/or disability in intensive care units admitting children (Pediatric Intensive Care Unit [PICU]) or both neonates and children (Neonatal and Pediatric Intensive Care Unit [NPICU]) and to describe available rehabilitation resources.

DESIGN: A cross-sectional study on two separate days, using a web questionnaire.

SETTING: NPICU/PICUs affiliated to the Groupe Francophone de Réanimation et Urgences Pédiatriques and the Réseau Mère-Enfant de la Francophonie.

PATIENTS: Children >1 month of gestationally corrected age.

MEASUREMENTS AND MAIN RESULTS: Disability was defined as a Pediatric Overall Performance Category >or=3 before admission and chronic conditions as hospitalization since birth or the presence before admission of any condition requiring ongoing pediatric subspecialty care that was expected to last >or=12 months. Intensivists indicated what rehabilitation services they would have ideally prescribed ("perceived needs") and those provided. Of 45 affiliated units, 8 PICUs and 15 NPICUs participated. Staff included or had access to a psychologist (11 and 5, respectively), a social worker (10 and 3), a physiotherapist (11 and 12), a "psychomotrician" (2 and 8), a child educator (1 and 6), and a speech-language pathologist (0 and 6). Among 289 recorded intensive care unit-days, 236 were analyzed (excluding those for children admitted after surgery): 57 concerned children hospitalized since birth and 179 children admitted from home. Among these 179 recorded intensive care unit-days, 107 concerned children with chronic conditions (including 50 concerning disabled children) and 72 previously healthy children. Thus, prevalence of chronic conditions, including children hospitalized since birth, was 67%. Rehabilitation services included respiratory physical therapy (552 visits), musculoskeletal physical therapy (71), neurologic physical therapy (37), rehabilitation for swallowing (11), and for speech-language disorders (1), representing 79% of perceived needs.

CONCLUSIONS: Prevalence of chronic conditions in NPICU/PICU was 67%. More attention must be paid to the rehabilitation care needs of patients during their NPICU/PICU stay and after discharge.

What become the decisions of limitation of treatments after discharge from the paediatric intensive care unit?

Arch Pediatr. 2008 Jul;15(7):1174-82. doi: 10.1016/j.arcped.2008.03.004. Epub 2008 May 5.

ABSTRACT

The fact that some children may survive despite a decision of limitation of treatments (DLT) is taken in Paediatric Intensive Care Unit (PICU) is a recent data. Although the French-speaking Group of Paediatric Intensive and Emergency Care (GFRUP) has published guidelines for limitation of treatments in PICU, outcome of these surviving children has not yet been studied.

PURPOSES: To evaluate transmission of data concerning DLT in PICU toward teams in charge of children after the PICU stay and to evaluate perennility of these decisions.

METHOD: Cohort study in children for whom DLT was discussed and who were discharged from PICU between 2002 and 2006. The study included an analysis of the medical files and discussions with the physicians in charge of children at the time of the study, including their responses to standardised scenarios concerning the outcome of their patients.

RESULTS: Among the 96 children for whom DLT was discussed in PICU, 37 were discharged toward another unit. Only 1 discharge letter mentioned the DLT. At the time of the study, the Pediatric Overall Performance Category (POPC) score had increased in 16 children and was stable in 12. All the 6 children with a worsening POPC score died, without PICU readmission. The physicians in charge of children after the PICU stay did not remember any DLT. For 18 children (including 8 with previous DLT) PICU readmission would be proposed in case of life-threatening event. Their median POPC score at the time of study was lower than that of other children (3 versus 4; p=0.001).

CONCLUSION: This study shows a lack of DLT data transmission, which is in contradiction with the GFRUP's guidelines. Correction of this lack is essential to improve cooperation between units in charge of these children.
