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.

The influence of prenatal and intrapartum antibiotics on intestinal microbiota colonisation in infants: A systematic review.

OBJECTIVES: The intestinal microbiota develops in early infancy and is essential for health status early and later in life. In this review we focus on the effect of prenatal and intrapartum maternally administered antibiotics on the infant intestinal microbiota. METHODS: A systematic literature search was conducted in PubMed and EMBASE. All studies reporting effect on diversity or microbiota profiles were included. RESULTS: A total of 4.030 records were encountered. A total of 24 articles were included in the final analysis. Infants from mothers exposed to antibiotics during delivery showed a decreased microbial diversity compared to non-exposed infants. The microbiota of infants exposed to antibiotics was characterised by a decreased abundance of Bacteriodetes and Bifidobacteria, with a concurrent increase of Proteobacteria. These effects were most pronounced in term vaginally born infants. CONCLUSION: Maternal administration of antibiotics seems to have profound effects on the infant gut microbiota colonisation. Interpretation of microbiota aberrations in specific populations, such as preterm and caesarean born infants, is complicated by multiple confounding factors and by lack of high quality studies and high heterogeneity in study design. Further research is needed to investigate the potential short- and long-term clinical consequences of these microbial alterations.

[Fibronectin test in threatened preterm labour: cost-saving but not yet widely implemented in the Netherlands]. / Fibronectinetest bij dreigende vroeggeboorte.

OBJECTIVE: Analysis of national implementation of the foetal fibronectin test in the diagnostics of threatened preterm labour in the Netherlands, and indication of the possible obstacles and consequences of implementation or no implementation. DESIGN: National questionnaire, retrospective cohort study and cost-effectiveness calculation. METHODS: We approached all hospitals in the Netherlands (n = 86) with a questionnaire on use of the fibronectin test. We also collected data on women who were referred to the Academic Medical Center (AMC), a tertiary care centre in Amsterdam, with symptoms of threatened preterm labour. We investigated whether the referred patients gave birth within 7 days, and whether unnecessary transfer to a centre with a neonatal intensive care unit (NICU) could have been avoided by implementation of the fibronectin test in the referring hospital. RESULTS: The fibronectin test was used in 34% of the hospitals and an additional 17% were in the process of implementation. The most important reasons not to use the fibronectin test were of a financial nature (50%). The cohort study included 96 women who were referred from secondary care. In our cohort, 36% of all transfers could have been avoided by implementation of the fibronectin test in secondary care. CONCLUSION: The fibronectin test can greatly reduce overtreatment and unnecessary transfer in threatened preterm labour, but implementation remains limited. Costs of the test are an obstacle for the referring hospitals, while implementation prevents unnecessary transport, admission and treatment of pregnant women, giving a potential saving of at least EUR 1,027,930 per year. Inclusion in the Netherlands Society for Obstetrics and Gynaecology (Nederlandse Vereniging voor Obstetrie en Gynaecologie, NVOG) guidelines would be a first step towards wider implementation. Slow implementation exemplifies a more widespread problem: the current reimbursement system does not stimulate such cost-saving innovations.

Effect of ventilation strategy and surfactant on inflammation in experimental pneumonia.

This study explored, the inflammatory response during experimental pneumonia in surfactant-depleted animals as a function of ventilation strategies and surfactant treatment. Following intratracheal instillation of Group B streptococci (GBS), surfactant-depleted piglets were treated with conventional (positive-end expiratory pressure (PEEP) of 5 cmH2O, tidal volume 7 mL x kg(-1)) or open lung ventilation. During the latter, collapsed alveoli were recruited by applying high peak inspiratory pressures for a short period of time, combined with high levels of PEEP and the smallest possible pressure amplitude. Subgroups in both ventilation arms also received exogenous surfactant. Conventionally ventilated healthy animals receiving GBS and surfactant-depleted animals receiving saline served as controls. In contrast with both control groups, surfactant-depleted animals challenged with GBS and conventional ventilation showed high levels of interleukin (IL)-8, tumour necrosis factor (TNF)-alpha and myeloperoxidase in bronchoalveolar lavage fluid after 5 h of ventilation. Open lung ventilation attenuated this inflammatory response, but exogenous surfactant did not. Systemic dissemination of the inflammatory response was minimal, as indicated by low serum levels of IL-8 and TNF-alpha. In conclusion, the current study indicates that the ventilation strategy, but not exogenous surfactant, is an important modulator of the inflammation during Group B streptococci pneumonia in mechanically ventilated surfactant-depleted animals.

Immunoglobulin M-enriched intravenous polyclonal immunoglobulins reduce bacteremia following Klebsiella pneumoniae infection in an acute respiratory distress syndrome rat model.

Mechanical ventilation is known to induce bacterial translocation from the lung into the systemic circulation. This study determined the effect of immunoglobulin M (IgM)-enriched polyclonal immunoglobulins on bacteremia due to ventilation-induced translocation in an acute respiratory distress syndrome (ARDS) rat model with Klebsiella-induced pneumonia. After whole lung lavage, Sprague-Dawley rats intravenously received either a high dose or a low dose of an immunoglobulin preparation, or an albumin solution as control, followed by an intratracheal injection of a Klebsiella pneumoniae solution. Blood colony-forming units (CFUs) in the treatment groups were significantly lower during the 3-hour ventilation period compared to the control group. The authors conclude that IgM-enriched polyclonal immunoglobulins lead to a reduction of bacteria in blood of surfactant-deficient, ventilated rats infected with Klebsiella pneumoniae.
