Delineating family needs in the transition from hospital to home for children with medical complexity: part 1, a meta-aggregation of qualitative studies.

BACKGROUND: Advances in diagnostic and therapeutic interventions for rare diseases result in greater survival rates, with on the flipside an expanding group of children with medical complexity (CMC). When CMC leave the protective hospital environment to be cared for at home, their parents face many challenges as they take on a new role, that of caregiver rather than care-recipient. However, an overview of needs and experiences of parents of CMC during transition from hospital-to-home (H2H) is lacking, which hampers the creation of a tailored H2H care pathway. Here we address this unmet medical need by performing a literature review to systematically identify, assess and synthesize all existing qualitative evidence on H2H transition needs of CMC parents. METHODS: An extensive search in Medline, PsychINFO and CINAHL (up to September 2022); selection was performed to include all qualitative studies describing parental needs and experiences during H2H transition of CMC. All papers were assessed by two independent investigators for methodological quality before data (study findings) were extracted and pooled. A meta-aggregation method categorized the study findings into categories and formulated overarching synthesized findings, which were assigned a level of confidence, following the ConQual approach. RESULTS: The search yielded 1880 papers of which 25 met eligible criteria. A total of 402 study findings were extracted from the included studies and subsequently aggregated into 50 categories and 9 synthesized findings: (1) parental empowerment: shifting from care recipient to caregiver (2) coordination of care (3) communication and information (4) training skills (5) preparation for discharge (6) access to resources and support system (7) emotional experiences: fatigue, fear, isolation and guilt (8) parent-professional relationship (9) changing perspective: finding new routines and practices. The overall ConQual Score was low for 7 synthesized findings and very low for 2 synthesized findings. CONCLUSIONS: Despite the variability in CMC symptoms and underlying (rare disease) diagnoses, overarching themes in parental needs during H2H transition emerged. We will augment this new knowledge with an interview study in the Dutch setting to ultimately translate into an evidence-based tailored care pathway for implementation by our interdisciplinary team in the newly established 'Jeroen Pit Huis', an innovative care unit which aims for a safe and sustainable H2H transition for CMC and their families.

Delineating family needs in the transition from hospital to home for children with medical complexity: part 2, a phenomenological study.

BACKGROUND: A systematic literature review on the transition from hospital-to-home (H2H) of families with a child with medical complexity (CMC), resulted in nine overarching themes. These demonstrated common needs and experiences despite the widely differing CMC diagnoses and family characteristics. However, none of the reported studies was conducted in the Netherlands, which hampers the creation of a tailored H2H care pathway, deemed essential for our recently established Transitional Care Unit in the Netherlands: the 'Jeroen Pit Huis'. Therefore, the aim of this study was to gain a deeper understanding of the needs and experiences of Dutch CMC parents on H2H transition and integrate these insights with the literature review into an evidence-based H2H care pathway for CMC and their families. METHODS: A descriptive phenomenological approach was applied. Heterogeneous purposeful sampling methods were used to recruit participants according to the following criteria: parents of CMC from various regions in the Netherlands, who spoke Dutch fluently and who had been discharged home from a tertiary hospital within the previous five years. Semi-structured, open-ended interviews were conducted via video call by two researchers, who transcribed the audio recordings verbatim. Thematic analysis methods were used to identify emerging themes from the individual transcripts, involving a third and fourth researcher to reach consensus. RESULTS: Between March and August 2021, 14 mothers and 7 fathers participated in 14 interviews. They elaborated on the H2H transition of 14 CMC with a wide range of underlying diseases: 7 male, 7 female, aged 6 months to 10 years. Eight overarching themes, consistent with the results of the systematic review, represent CMC parental needs and experiences during the H2H process in the Netherlands: (1) autonomy, (2) division of tasks and roles, (3) family emotions, (4) impact on family life, (5) communication, (6) coordination of care, (7) support system and (8) adaptation. CONCLUSIONS: The H2H needs and experiences reported by the CMC families in this study align with the results of our systematic review. The H2H transition process is not linear but continuous, and should extend beyond the specific medical needs of the CMC to holistic care for the family as a whole. The overarching care needs and experiences, expressed by all CMC families, regardless of underlying symptoms and diagnoses, inform the H2H care pathway and its future evaluation. Our studies highlight the necessity to focus on the family needs rather than on the specific illness of the child, as well as the value of our interdisciplinary care team partnering with parents in the 'Jeroen Pit Huis' towards a safe and sustainable transition home.

How doctors actually (do not) involve families in decisions to continue or discontinue life-sustaining treatment in neonatal, pediatric, and adult intensive care: A qualitative study.

BACKGROUND: Intensive care doctors have to find the right balance between sharing crucial decisions with families of patients on the one hand and not overburdening them on the other hand. This requires a tailored approach instead of a model based approach. AIM: To explore how doctors involve families in the decision-making process regarding life-sustaining treatment on the neonatal, pediatric, and adult intensive care. DESIGN: Exploratory inductive thematic analysis of 101 audio-recorded conversations. SETTING/PARTICIPANTS: One hundred four family members (61% female, 39% male) and 71 doctors (60% female, 40% male) of 36 patients (53% female, 47% male) from the neonatal, pediatric, and adult intensive care of a large university medical center participated. RESULTS: We identified eight relevant and distinct communicative behaviors. Doctors' sequential communicative behaviors either reflected consistent approaches-a shared approach or a physician-driven approach-or reflected vacillating between both approaches. Doctors more often displayed a physician-driven or a vacillating approach than a shared approach, especially in the adult intensive care. Doctors did not verify whether their chosen approach matched the families' decision-making preferences. CONCLUSIONS: Even though tailoring doctors' communication to families' preferences is advocated, it does not seem to be integrated into actual practice. To allow for true tailoring, doctors' awareness regarding the impact of their communicative behaviors is key. Educational initiatives should focus especially on improving doctors' skills in tactfully exploring families' decision-making preferences and in mutually sharing knowledge, values, and treatment preferences.

Epidemiology and Etiology of Severe Childhood Encephalitis in The Netherlands.

BACKGROUND: Limited data are available on childhood encephalitis. Our study aimed to increase insight on clinical presentation, etiology, and clinical outcome of children with severe encephalitis in the Netherlands. METHODS: We identified patients through the Dutch Pediatric Intensive Care Evaluation database and included children diagnosed with encephalitis <18 years of age admitted to 1 of the 8 pediatric intensive care units (PICU) in the Netherlands between January 2003 and December 2013. We analyzed demographic characteristics, clinical symptoms, neurologic imaging, etiology, treatment and mortality. RESULTS: We included 121 children with a median age of 4.6 years (IQR 1.3-9.8). The most frequently described clinical features were headache (82.1%), decreased consciousness (79.8%) and seizures (69.8%). In 44.6% of the children, no causative agent was identified. Viral- and immune-mediated encephalitis were diagnosed in 33.1% and 10.7% of the patients. A herpes simplex virus infection (13.2%) was mainly seen in children <5 years of age, median age, 1.73 years (IQR 0.77-5.01), while immune-mediated encephalitis mostly affected older children, median age of 10.4 years (IQR, 3.72-14.18). An age of ≥ 5 years at initial presentation was associated with a lower mortality (OR 0.2 [CI 0.08-0.78]). The detection of a bacterial (OR 9.4 [CI 2.18-40.46]) or viral (OR 3.7 [CI 1.16-11.73]) pathogen was associated with a higher mortality. CONCLUSIONS: In almost half of the Dutch children presenting with severe encephalitis, a causative pathogen could not be identified, underlining the need for enhancement of microbiologic diagnostics. The detection of a bacterial or viral pathogen was associated with a higher mortality.

Human respiratory syncytial virus infection in the pre-clinical calf model.

Human respiratory syncytial virus (hRSV) is the most important respiratory pathogen in young children worldwide. Experimental modelling of hRSV disease by bovine RSV (bRSV) infection in calves provides an important tool for developing new strategies for prevention and treatment. Depending on the scientific hypothesis under investigation, this cognate host-virus model might have the disadvantage of using a highly related but not genetically identical virus. In this study, we aim to describe viral kinetics and (clinical) disease characteristics in calves inoculated with hRSV. Our results show that hRSV infects the upper and, to a lesser extent, the lower respiratory tract of calves. Infection causes upper airway clinical disease symptoms and neutrophilic infiltration of the lower airways. We conclude that a hRSV model in calves may aid future research involving distinct scientific questions related to hRSV disease in children.

A neonate with marked prolonged mixed apneas and CHARGE syndrome: a case report.

BACKGROUND: Upper airway abnormalities in the newborn are associated with obstructive breathing but not with mixed apneas. A tracheostomy is necessary to treat severe obstructive apneas but will not have an effect on the central part of the mixed apneas. As far as we know, this is the first case report describing disappearance of severe mixed apneas after tracheostomy in a 7-week-old infant. CASE PRESENTATION: We report a case of a white female neonate with anatomical upper airway abnormalities and severe mixed apneas with desaturations needing respiratory support. Polysomnography revealed striking mixed apneas, starting as a prolonged central apnea and merging into an obstructive apnea, and were not appropriate for her age. Additional examination revealed no explanation for the central component of the mixed apneas. Because of persistent, severe desaturations, she needed respiratory support with failure to wean. Finally, a tracheostomy was performed to treat the obstructive apneas, but unexpectedly the central apneas also resolved. Recently, additional genetic testing revealed that she has CHARGE syndrome (coloboma of the eye, heart defects, atresia of the choanae, retardation of growth and development, genital and/or urinary abnormalities, and ear abnormalities and deafness). CONCLUSIONS: Mixed apneas are not a common feature in the newborn or infant with upper airway abnormalities. However, treatment with tracheostomy in our patient (day 46 postpartum) with anatomical upper airway abnormalities resolved not only obstructive apneas but also, unexpectedly, severe mixed apneas. Surprisingly, a posttracheostomy polygraph showed only short central apneas appropriate for age.

Broadly Reactive Anti-Respiratory Syncytial Virus G Antibodies from Exposed Individuals Effectively Inhibit Infection of Primary Airway Epithelial Cells.

Respiratory syncytial virus (RSV) causes severe respiratory disease in young children. Antibodies specific for the RSV prefusion F protein have guided RSV vaccine research, and in human serum, these antibodies contribute to >90% of the neutralization response; however, detailed insight into the composition of the human B cell repertoire against RSV is still largely unknown. In order to study the B cell repertoire of three healthy donors for specificity against RSV, CD27+ memory B cells were isolated and immortalized using BCL6 and Bcl-xL. Of the circulating memory B cells, 0.35% recognized RSV-A2-infected cells, of which 59% were IgA-expressing cells and 41% were IgG-expressing cells. When we generated monoclonal B cells selected for high binding to RSV-infected cells, 44.5% of IgG-expressing B cells and 56% of IgA-expressing B cells reacted to the F protein, while, unexpectedly, 41.5% of IgG-expressing B cells and 44% of IgA expressing B cells reacted to the G protein. Analysis of the G-specific antibodies revealed that 4 different domains on the G protein were recognized. These epitopes predicted cross-reactivity between RSV strain A (RSV-A) and RSV-B and matched the potency of antibodies to neutralize RSV in HEp-2 cells and in primary epithelial cell cultures. G-specific antibodies were also able to induce antibody-dependent cellular cytotoxicity and antibody-dependent cellular phagocytosis of RSV-A2-infected cells. However, these processes did not seem to depend on a specific epitope. In conclusion, healthy adults harbor a diverse repertoire of RSV glycoprotein-specific antibodies with a broad range of effector functions that likely play an important role in antiviral immunity.IMPORTANCE Human RSV remains the most common cause of severe lower respiratory tract disease in premature babies, young infants, the elderly, and immunocompromised patients and plays an important role in asthma exacerbations. In developing countries, RSV lower respiratory tract disease has a high mortality. Without an effective vaccine, only passive immunization with palivizumab is approved for prophylactic treatment. However, highly potent RSV-specific monoclonal antibodies could potentially serve as a therapeutic treatment and contribute to disease control and mortality reduction. In addition, these antibodies could guide further vaccine development. In this study, we isolated and characterized several novel antibodies directed at the RSV G protein. This information can add to our understanding and treatment of RSV disease.

Neutrophil Extracellular Traps in Respiratory Disease: guided anti-microbial traps or toxic webs?

Neutrophil recruitment to the airways and lungs is a major hallmark of many respiratory diseases. One of the more recently discovered unique innate immune effector mechanisms of neutrophils is the formation of neutrophil extracellular traps (NETs), consisting of an extracellular network of DNA fibers studded with nuclear and granule proteins. Although in the respiratory system NETs contribute to capture and inactivation of bacteria, fungi and viruses, there is a delicate 'balance' between aid and damage to the host. Accumulating evidence now suggests that NETs can have direct cytotoxic effects to lung epithelial and endothelial cells and can contribute to airway obstruction. As such, NETs may play an important role in the pathogenesis of respiratory diseases. The purpose of this review is to give an up-to-date overview of the current status of NETs in respiratory diseases. We examine both experimental and clinical data concerning the role of NETs in host defence as well as immunopathology, with special attention paid to the literature relevant for the paediatric pulmonology community. Finally, we discuss future treatment strategies that may target the formation of NETs in the airways and lungs.

Association between C-reactive protein levels and outcome in acute lung injury in children.

UNLABELLED: High plasma C-reactive protein (CRP) levels are associated with favorable outcome in adults with acute lung injury (ALI). The association between CRP levels and outcome has not been studied in ALI in children. We performed a historical cohort study in 93 mechanically ventilated children (0-18 years) with ALI. The CRP level within 48 h of disease onset was tested for association with 28-day mortality and ventilator-free days (VFD). Clinical parameters and ventilator settings were evaluated for possible confounding. Fourteen patients died within 28 days. The median (interquartile range) CRP level in nonsurvivors was 126 mg/L (64; 187) compared with 56 mg/L (20; 105) in survivors (p = 0.01). For every 10-mg/L rise in CRP level, the unadjusted odds (95% confidence interval (95% CI)) for mortality increased 8.7% (2.1-15.8%). Cardiovascular organ failure at onset of ALI was the strongest predictor for mortality (odds ratio, 30.5 (6.2-152.5)). After adjustment for cardiovascular organ failure, for every 10-mg/L rise in CRP level, the OR (95% CI) for mortality increased 4.7% (-2.7-12.6%; p = 0.22). Increased CRP levels were associated with a decrease in VFD (ρ = -0.26, p = 0.01). CONCLUSION: increased plasma CRP levels are not associated with favorable outcome in ALI in children. This is in contrast with findings in adults with ALI.

Mannose-binding lectin (MBL) as prognostic factor in paediatric oncology patients.

Deficiency of mannose-binding lectin (MBL) has been suggested to influence duration of febrile neutropenia and prognosis in paediatric oncology patients. However, there is no consensus on the definition of MBL deficiency. In a cohort of children with cancer, we investigated (i) how to determine MBL deficiency and (ii) whether MBL is a prognostic factor for disease severity. In 222 paediatric oncology patients, 92 healthy children and 194 healthy adults, MBL plasma levels and MBL2 genotype (wild-type: A, variant: O) were determined. Event-free survival (EFS), overall survival (OS) and paediatric intensive care unit (PICU) admissions were recorded prospectively. In febrile neutropenic patients admitted to the PICU, disease severity was assessed by clinical, microbiological and laboratory parameters. An optimal cut-off value for MBL deficiency was determined to be < 0·20 µg/ml. Wild-type MBL2 genotype patients, including the XA/XA haplotype, had increased MBL levels compared to healthy individuals. MBL deficiency was associated with decreased EFS (P = 0·03), but not with need for PICU admission. A trend for a twice increased frequency of septic shock (80% versus 38%, P = 0·14), multiple organ failure (40% versus 17%, P = 0·27) and death (40% versus 21%, P = 0·27) was observed in the absence of microbiological findings. MBL deficiency was associated with decreased EFS and possibly with an increased severity of disease during PICU admission after febrile neutropenia in the absence of any association with microbiological findings. These findings suggest prognosis to be worse in MBL-deficient compared to MBL-sufficient paediatric oncology patients.

[Influenza in children undergoing chemotherapy]. / Influenza bij kinderen die chemotherapie ondergaan.

Two paediatric cancer patients were found to have influenza shortly after receiving chemotherapy. Both presented with neutropenic fever. The first patient, a 15-year-old boy with Hodgkin's lymphoma, recovered without complications. The second patient, a 15-month-old-girl with metastatic Wilms' tumour, died due to severe infectious complications. These cases illustrate that common viruses, such as the influenza virus, can cause fulminant secondary infections in immunocompromised patients. Viruses, including the influenza virus, should always be considered as pathogens in patients with neutropenic fever, and influenza vaccination should be considered in these high-risk patients.

High incidence of acute lung injury in children with Down syndrome.

OBJECTIVE: Acute respiratory tract infection is a common reason for hospitalization in children with Down syndrome (CDS) and is characterized by a high morbidity. The severe course of disease in CDS may be related to a higher incidence of acute lung injury (ALI). This study evaluated the incidence of ALI and acute respiratory distress syndrome (ARDS) in mechanically ventilated CDS. DESIGN AND SETTING: Retrospective cohort study in a pediatric ICU. PATIENTS AND PARTICIPANTS: Cases were all mechanically ventilated CDS admitted to our unit between January 1998 and July 2005. All mechanically ventilated patients without Down syndrome from January 1998 to January 2001 served as controls. Postoperative patients (cases and controls) and those with a cardiac left to right shunt were excluded. MEASUREMENTS AND RESULTS: The main outcome measure was the incidence of ALI and ARDS. The criteria for ALI were met in 14 of 24 CDS (58.3%) in 41 of 317 of controls (12.9%; OR 9.4, 95% CI 3.9-22.6). The criteria for ARDS were met in 11 of 24 CDS (46%) and in 21 of 317 of controls (7%; OR 11.9, 95% CI 4.8-29.8). None of the CDS with ALI died; in the control group ten patients with ALI died. CONCLUSIONS: CDS had a significantly higher incidence of ALI and ARDS than children without Down syndrome. The explanation for this remains to be elucidated; further study is necessary before clinical implications become clear.

Prophylactic antibiotics for preventing early central venous catheter Gram positive infections in oncology patients.

BACKGROUND: Long-term tunnelled central venous catheters (TCVCs) are increasingly used when treating oncology patients. Despite international guidelines on sterile insertion, appropriate catheter maintenance and use, infections still a complication of TCVC. These infections are mainly caused by Gram-positive bacteria. Antimicrobial prevention strategies aimed at these micro-organisms could potentially decrease the majority of TCVC infections. The aim of this review was to evaluate the efficacy of antibiotics in the prevention of early TCVC infections. OBJECTIVES: To determine the efficacy of administering antibiotics prior to insertion of a TCVC with or without vancomycin/heparin flush technique in the first 45 days after insertion of the catheter to prevent Gram-positive catheter-related infections in oncology patients. SEARCH STRATEGY: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) to July 2006. MEDLINE (1966 to 2006) and EMBASE (1966 to 2006). Reference lists from relevant articles were scanned and conference proceedings were hand searched. The authors of eligible studies were contacted to obtain additional information. SELECTION CRITERIA: We selected RCTs which administered prophylactic antibiotics prior to insertion of the TCVC, and RCTs using the combination of an antibiotic and heparin to flush the CVC in oncology patients (both adults and children). DATA COLLECTION AND ANALYSIS: The studies identified were assessed and the data extracted independently by the two authors. Authors were contacted for details of randomization, and a quality assessment was carried out. The analysis was carried out using the standard Cochrane software package, RevMan 4.2. MAIN RESULTS: We included nine trials with a total of 588 patients. Four reported on vancomycin/teicoplanin prior to insertion of the TCVC compared to placebo, and five trials reported on antibiotic flushing combined with heparin, compared to heparin flushing only. The overall effect of administering an antibiotic prior to insertion of the catheter decreases the number of Gram positive TCVC infections (odds ratio [OR] = 0.42, 95% confidence interval (CI) 0.13 to 1.31), this effect is not significant. Flushing the TCVC with antibiotics and heparin proved to be beneficial (OR = 0.43, 95% CI 0.21 to 0.87). For intraluminal colonization the baseline infection rate is 15% which leads to a number needed to treat (NNT) of 13 (95 % CI 5 to 23). AUTHORS' CONCLUSIONS: Flushing of the catheter with a vanco/heparin lock solution leads to a positive overall effect. Depending on the baseline TCVC infection rate it is justified to flush the catheter with a combination of an antibiotic and heparin, if the catheter related infection-rate is high.

Inhaled corticosteroids during acute bronchiolitis in the prevention of post-bronchiolitic wheezing.

BACKGROUND: Acute bronchiolitis in infants and young children is associated with long-term airway disease also known as post-bronchiolitic wheezing. Two major hypotheses have been proposed to explain the association between bronchiolitis and PBW. The first hypothesis considers bronchiolitis to be the first manifestation of recurrent wheezing in infants and children who are susceptible to obstructive airway disease. The second hypothesis suggests that the infection and concomitant inflammatory reaction in the acute phase leads to airway epithelium injury resulting in long-term obstructive airway disease. In line with the latter hypothesis, corticosteroids may have a beneficial effect on the prevention of post-bronchiolitic wheezing. OBJECTIVES: The objective of this review was to evaluate the effect of inhaled corticosteroids, started during the acute phase of bronchiolitis, on the prevention of post-bronchiolitic wheezing. SEARCH STRATEGY: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 3, 2006) which contains the Cochrane Acute Respiratory Infections Group's trials register, MEDLINE (1966 to September 2006), EMBASE (1980 to September 2006) and Current Contents (September 2006). Abstracts and reports of congresses (ERS 1999 to September 2005, ATS 1999 to September 2005) were obtained. We contacted experts in the field and pharmaceutical companies for ongoing or unpublished studies. SELECTION CRITERIA: Randomised placebo-controlled trials studying the effect of inhaled corticosteroids in children younger than two years of age with the clinical diagnosis of acute bronchiolitis were included. DATA COLLECTION AND ANALYSIS: Two authors independently extracted data and assessed trial quality using the Jadad 5-point scale. MAIN RESULTS: Five studies matched the inclusion criteria, with a median Jadad score of 4 (Inter Quartile Range 3 to 4), involving 374 infants. Pooling of the data was limited, due to the clinical diversity of the studies. However, no effect of inhaled corticosteroids in the prevention of wheezing (diary records or GP diagnosed), hospital re-admissions or use of corticosteroids or bronchodilators could be demonstrated. Duration of therapy, length of follow up or causative agent (respiratory syncytial virus or not) did not influence the pooled effect. In the three studies that also evaluated the adverse events, none were reported. AUTHORS' CONCLUSIONS: This review does not demonstrate an effect of inhaled corticosteroids given during the acute phase of bronchiolitis in the prevention of post-bronchiolitic wheezing. The small number of included participants and the inability to pool all clinical outcomes precludes us from making strong recommendations.

Absence of human metapneumovirus co-infection in cases of severe respiratory syncytial virus infection.

It has been suggested that co-infection of human metapneumovirus (hMPV) in severe respiratory syncytial (RSV) virus bronchiolitis is very common. To evaluate the epidemiology of hMPV co-infection in children with severe lower respiratory tract infection caused by RSV virus. This was an observational cohort study in which hMPV and RSV viral load was measured by RT-PCR in tracheal specimens from the target population. hMPV could not be detected in any of the 30 mechanically ventilated children with RSV lower respiratory tract infection. Our study suggests that hMPV co-infection is not very common in severe RSV lower respiratory tract infection.

Prophylactic antibiotics for preventing early Gram-positive central venous catheter infections in oncology patients, a Cochrane systematic review.

OBJECTIVE: Long-term tunnelled central venous catheters (TCVC) are increasingly used in oncology patients. Infections are a frequent complication of TCVC, mostly caused by Gram-positive bacteria. The objective of this review is to evaluate the efficacy of antibiotics in the prevention of early Gram-positive TCVC infections, in oncology patients. DATA SOURCES: We searched MEDLINE, EMBASE, and the Cochrane Controlled Trials Register up to July 2003. REVIEW METHODS: We selected randomised controlled trials (RCT) evaluating prophylactic antibiotics prior to insertion of the TCVC, and the combination of an antibiotic and heparin to flush the TCVC, in paediatric and adult oncology patients. The primary outcome was documented Gram-positive bacteraemia in patients with a TCVC. All trials identified were assessed and the data extracted independently by two reviewers. RESULTS: There were nine trials included. Four trials reported on vancomycin/teicoplanin prior to insertion of the TCVC compared to no antibiotics. There was no reduction in the number of Gram-positive TCVC infections with an Odds ratio of 0.42 (95% confidence interval 0.13-1.31). Five trials studied flushing of the TCVC with a vancomycin/heparin solution compared to heparin flushing only. This method decreased the number of TCVC infections significantly with an Odds ratio of 0.43 (95% CI 0.21-0.87). CONCLUSION: Flushing the TCVC with a vancomycin/heparin solution reduced the incidence of Gram-positive infections.

[Unnatural and unexplained death in a paediatric intensive-care unit, 1993-2002]. / Niet-natuurlijke en onverklaarde dood op een intensive care voor kinderen, 1993-2002.

OBJECTIVE: To analyse the causes of unnatural death in a general paediatric intensive-care unit. DESIGN: Retrospective and descriptive. METHODS: The cause of death was reviewed for all deceased children who were admitted to the paediatric intensive-care unit of the Emma Children's Hospital/Academic Medical Centre in Amsterdam, the Netherlands from 1993 through 2002. Three investigators independently categorised the cause of death as 'natural' or 'unnatural'. Unnatural death was defined as death by external cause, such as drowning, suffocation or violence, whether intentional or not. For all patients who died an unnatural death the cause of death and (if available) results of autopsy were analysed. RESULTS: During the study period, 5523 patients were admitted to the ICU, of whom 360 (6.5%) died during the period of admission. In 45 (12.5%) of these this was an unnatural death. In 7 (16%) patients there was a suspicion of death by deliberately caused injury. In 4 of these patients forensic autopsy was performed. The results of autopsy confirmed the suspicion of child battery in 3 patients, whereas in 1 case the diagnosis was refuted. CONCLUSION: In 16% of the children who died of unnatural causes there was a suspicion of child battery. A forensic autopsy was useful in all cases to confirm or refute the suspicion of child battery, but was not carried out in all cases.

Prophylactic antibiotics for preventing early central venous catheter Gram positive infections in oncology patients.

BACKGROUND: Long-term tunnelled central venous catheters (TCVC) are increasingly used in oncology patients. Despite guidelines on insertion, maintenance and use, infections remain an important complication. Most infections are caused by Gram-positive bacteria. Therefore antimicrobial prevention strategies aimed at these micro-organisms could potentially decrease the majority of the TCVC infections. OBJECTIVES: To determine the efficacy of administering antibiotics prior to insertion of a TCVC with or without vancomycin/heparin flush technique in the first 45 days after insertion of the catheter to prevent Gram-positive catheter-related infections in oncology patients. SEARCH STRATEGY: We searched MEDLINE, EMBASE,and CENTRAL up to July 2001. Reference lists from relevant articles were scanned and conference proceedings were hand searched. The authors of eligible studies were contacted to obtain additional information. SELECTION CRITERIA: We selected randomized controlled trials giving prophylactic antibiotics prior to insertion of the TCVC, and trials using the combination of an antibiotic and heparin to flush the TCVC in oncology patients. DATA COLLECTION AND ANALYSIS: Two reviewers independently assessed the studies for inclusion, extracted the data and assessed the quality. MAIN RESULTS: We included eight trials totalling 527 patients. Four reported on vancomycin/teicoplanin prior to insertion of the TCVC, and four reported on antibiotic flushing combined with heparin. The overall effect of an antibiotic prior to catheter insertion decreases the number of Gram-positive TCVC infections (odds ratio [OR] = 0.55, 95% confidence interval [CI] 0.29 to1.04). Given an expected infection rate of TCVC during the first 45 days of up to 30% this OR implies that the number needed to treat (NNT) will be 10 (95% CI 4 to13), this means vancomycin needs to be given to 10 patients to prevent one TCVC infection. Flushing the TCVC with antibiotics and heparin proved to be beneficial (OR = 0.35, 95% CI 0.16 -to 0.77). For intraluminal colonization the baseline infection-rate is 15% which leads to a NNT of 13 (95% CI 5 to 23). REVIEWER'S CONCLUSIONS: Both interventions lead to a positive overall effect but should be considered with care due to the small number of studies. Depending on the baseline TCVC infection rate it is justified to administer antibiotics prior to the TCVC insertion or to flush the catheter with a combination of an antibiotic and heparin, if the catheter-related infection rate is high.
