Assessment methods in respiratory medicine training in Europe: current status and future needs.

There is a perceived need for harmonisation of training standards in medicine across Europe. Assessment methodology is a fundamental part of this harmonisation. Assessment may be: summative, measuring competency at the end of training, usually in a pass/fail mode; or formative, assessing strengths and weaknesses during training with a view to optimising performance. A survey of experienced respiratory medicine trainers in Europe was undertaken to discover the formative and summative assessment methods being used, and to explore the use of workplace-based assessments (WBAs). Structured interviews were sought with experienced trainers in adult and paediatric respiratory medicine. 35 trainers from 22 (71%) out of 31 countries were interviewed. The number of types of summative assessments required at the end of training varied from 0 to 4 including clinical (25%), written (44%) and oral (47%) examinations. Four respondents required a research thesis as a proof of clinical competence. WBA was not commonly used. Only 14% of respondents reported using a formal case-based discussion, 20% used a form of multisource feedback and 25% described some form of formal assessment of procedural skills. However, 77% of all respondents expressed a wish to have access to case-based discussion and 72% wanted to have a facility for multisource feedback. The majority also wanted training in the use of these tools. Almost half of the respondents had received no formal training in educational supervision and 80% of all respondents expressed a wish to receive such training. The findings suggest that there is no adequate process of ensuring uniform standards for specialist accreditation in Europe, and demonstrate a need and desire among trainers for more WBA tools and training in their use to be made available.

Update of the European paediatric respiratory medicine syllabus.

The 10-year-old European syllabus for paediatric respiratory medicine (PRM; also known as paediatric pulmonology) was updated by a consensus-based method using an expert task force for redrafting, and a subsequent Delphi process to achieve consensus. There was a high degree of consensus for the final syllabus, which has been streamlined and made more relevant to current practice. All modules are now mandatory apart from the undertaking of research projects, which is optional. Although there are still a number of countries in Europe which do not recognise PRM as a separate subspecialty, there are paediatric respiratory physicians practising in every country in Europe, and a current and harmonised European syllabus in the subspecialty remains important for defining the training and areas of practice of PRM practitioners.

Pneumothorax from subpleural blebs-a new association of sotos syndrome?

We describe two unrelated patients with molecularly confirmed Sotos syndrome with multiple subpleural blebs and pneumothorax. We propose this as a new association. Patient 1 is a 3-year-old boy with a 1.9 Mb interstitial deletion of the long arm of chromosome 5, with breakpoints at q35.2 and q35.3, encompassing NSD1 and Patient 2 is a 9-year-old girl with a de novo truncating mutation within NSD1. Both patients presented with sudden onset dyspnea due to a unilateral pneumothorax: Patient 1 at the age of 18 months and Patient 2 at 9 years. In both, the pneumothorax recurred following removal of the chest drain and, on further investigations, multiple subpleural blebs were identified necessitating a pleurodesis and tissue resection. This is the first report of multiple subpleural blebs leading to pneumothorax in association with Sotos syndrome. Given the similar and unusual presentation in the two affected patients, we suggest that this may be a real association, albeit a rare one. While screening would not be advocated for such a rare association, we recommend that clinicians consider pneumothorax in patients with Sotos syndrome and sudden onset of dyspnea and are aware that it may be refractory to first line treatment.

Complications in pediatric scoliosis surgery.

BACKGROUND: Scoliosis surgery in childhood is associated with a range of postoperative complications that may require admission to the pediatric intensive care unit (PICU) or high-dependency unit (HDU). AIM: The aim of this study was to identify preoperative factors associated with PICU and HDU admissions after corrective surgery and devise a scoring system that could be used by clinicians to predict the level of dependency required postoperatively. METHODS: A retrospective case note review was carried out in 90 patients who underwent corrective scoliosis surgery at Sheffield Children's Hospital (SCH) between January 2008 and October 2010. Predictors of PICU and HDU requirement postoperatively were identified and a simple scoring system created using multiple logistic regression and receiver operator characteristic (ROC). RESULTS: There was a statistically significant difference in the preoperative parameters (pulmonary function, Cobb angle, and number of vertebrae fused) of those patients who required PICU or HDU care compared with those who did not. The area under the receiver operator characteristic curve for the final scoring system was 0.95 for PICU admission and 0.87 for HDU admission at the optimal cut-off point, demonstrating good diagnostic accuracy. CONCLUSIONS: The authors have identified a significant relationship between preoperative variables and the levels of dependency required postoperatively and have proposed a scoring system which can be used to aid decision-making involving bed planning for patients after corrective scoliosis surgery. However, this work is based on the clinical course of a single set of patients who had surgery in a single tertiary center and has not been tested on patients from other centers.

Sleep physiology and sleep-disordered breathing: the essentials.

Sleep is essential, but poses a risk to breathing in some children. We have outlined the developmental changes in sleep patterns and physiology, and the evidence of deleterious effects of sleep deprivation and of sleep-related breathing disorder (SRBD). Some factors increase the risk of adenotonsillar surgery and should be excluded before contemplating surgery in a secondary care setting. Screening for SRBD is indicated in some conditions, which are discussed. Although simple studies may suffice for many patients, there are a few who need more detailed assessment with polysomnography. A managed clinical network would be the most appropriate model to ensure appropriate organisation and utilisation of scarce resources in this area.

Awake and asleep oxygen saturations in infants with chronic neonatal lung disease.

AIM: There is uncertainty about the best method of withdrawing supplemental oxygen in babies with chronic neonatal lung disease (CNLD). Some authors advocate withdrawal of oxygen in the day, but continuing supplementation during sleep, based on early work suggesting that oxygen saturations are lower during sleep, which did not accord with our clinical impression. We re-examined the hypothesis that babies have lower saturations while asleep. METHODS: We studied infants with CNLD during the day, while awake and asleep. We recorded video with simultaneous real-time capture of oxygen saturation (SpO2), heart rate and plethysmographic waveform from pulse oximetry. Behavioural state was scored using observation and video and classified as awake (feeding, active or quiet) or sleep. RESULTS: Thirteen infants had analysable data, although one had strikingly lower SpO2 values while awake and was excluded from analysis. The infants had a median gestation of 26 weeks and were studied at a median (range) postmenstrual age of 66 (37-130) weeks, for 229 (89-330) min. Mean SpO2 was 97.6% during sleep and 97.0% awake (p=0.011). CONCLUSION: Babies with CNLD have lower oxygen saturation while awake. There is no physiological justification for increasing oxygen during sleep, or withdrawing selectively during the daytime, although larger studies are needed to confirm this finding.

Oxygen titration strategies in chronic neonatal lung disease.

The history of oxygen therapy in neonatology has been littered with error. Controversies remain in a number of areas of oxygen therapy, including targets and strategies in supplemental oxygen therapy in Chronic Neonatal Lung Disease (CNLD). This article reviews some of these controversies, and makes some recommendations based on the available evidence. In graduates of neonatal units who are left with CNLD, oxygen saturation should be kept above 93-95%, with levels below 90% being avoided as far as possible. Titration of oxygen should be done using oximetry recordings which include periods of different activities. Weaning of oxygen supplementation should only be done based on satisfactory recordings during a trial of a lower flow. There is insufficient evidence to say whether weaning for increasing hours a day or stepwise weaning to a continuous lower flow is a better method.
