Abstract
UNLABELLED Most patients with acute bronchiolitis have a mild course and only require outpatient care. However, some of them have to go to emergency departments, because they have respiratory distress or feeding problems. There, they frequently receive diagnostic and therapeutic procedures. We want to know the variability and appropriateness of these procedures. A cross-sectional study (October 2007 to March 2008) was carried out on 2,430 diagnosed cases of bronchiolitis in hospital emergency departments, which required no hospitalization. An analysis of the appropriateness of the treatments was made in 2,032 cases gathered in ten departments with at least 100 cases, using as criterion the recommendations of a consensus conference. We estimated the adjusted percentages of each department. Most of the bronchiolitis were mild, in spite that they underwent multiple diagnostic and therapeutic procedures. In the acute phase, different treatments were used: inhaled beta 2 agonists (61.4%), antipyretics (17.1%), oral steroids (11.3%), and nebulized adrenaline (9.3%). In the maintenance phase, the most common treatments were: inhaled beta 2 agonists (50.5%), oral steroids (17%), oral beta 2 agonists (14.9%), and antibiotics (6.1%). The 64% of the treatments used in the acute phase and the 55.9% in the maintenance phase were considered inappropriate in the appropriateness analysis; a great heterogeneity among centers was found. CONCLUSIONS There are discrepancies between clinical practice and evidence-based management of bronchiolitis in Spanish emergency departments. Inappropriate treatments were used in more than half of patients. The wide variation between centers shows the influence of local prescribing habits and reveals the scope for improvement.

Abstract
BACKGROUND Surfactant is usually given to mechanically ventilated preterm infants via an endotracheal tube to treat respiratory distress syndrome. We tested a new method of surfactant application to spontaneously breathing preterm infants to avoid mechanical ventilation. METHOD In a parallel-group, randomised controlled trial, 220 preterm infants with a gestational age between 26 and 28 weeks and a birthweight less than 1·5 kg were enrolled in 12 German neonatal intensive care units. Infants were independently randomised in a 1:1 ratio with variable block sizes, to standard treatment or intervention, and randomisation was stratified according to centre and multiple birth status. Masking was not possible. Infants were stabilised with continuous positive airway pressure and received rescue intubation if necessary. In the intervention group, infants received surfactant treatment during spontaneous breathing via a thin catheter inserted into the trachea by laryngoscopy if they needed a fraction of inspired oxygen more than 0·30. The primary endpoint was need for any mechanical ventilation, or being not ventilated but having a partial pressure of carbon dioxide more than 65 mm Hg (8·6 kPa) or a fraction of inspired oxygen more than 0·60, or both, for more than 2 h between 25 h and 72 h of age. Analysis was by intention to treat. This study is registered, number ISRCTN05025922. FINDINGS 108 infants were assigned to the intervention group and 112 infants to the standard treatment group. All infants were analysed. On day 2 or 3 after birth, 30 (28%) infants in the intervention group were mechanically ventilated versus 51 (46%) in the standard treatment group (number needed to treat 6, 95% CI 3-20, absolute risk reduction 0·18, 95% CI 0·30-0·05, p=0·008). 36 (33%) infants in the intervention group were mechanically ventilated during their stay in the hospital compared with 82 (73%) in the standard treatment group (number needed to treat: 3, 95% CI 2-4, p<0·0001). The intervention group had significantly fewer median days on mechanical ventilation, (0 days. IQR 0-3 vs 2 days, 0-5) and a lower need for oxygen therapy at 28 days (30 infants [30%] vs 49 infants [45%], p=0·032) compared with the standard treatment group. We recorded no differences between groups for mortality (seven deaths in the intervention group vs five in the standard treatment group) and serious adverse events (21 vs 28). INTERPRETATION The application of surfactant via a thin catheter to spontaneously breathing preterm infants receiving continuous positive airway pressure reduces the need for mechanical ventilation.

Abstract
BACKGROUND AND OBJECTIVES The current circumstances of patients treated with home oxygen therapy (HOT) for respiratory failure are understood relatively well, whereas those of HOT patients with heart failure has not been extensively examined. Furthermore, investigation of the fundamental realities of disease checkups cooperation between specialist hospitals and clinics regarding HOT patients has not been satisfactory. For these reasons, we attempted to clarify the circumstances of HOT patients at clinics, respiratory specialist hospitals, and cardiovascular specialist hospitals, in the context of those who work in the medical sphere in Japan (approx. 2 million people). METHODS An epidemiological survey was simultaneously sent to district clinics, respiratory specialist hospitals, and cardiovascular specialist hospitals, all located in Tochigi Prefecture in Japan, and which were anticipated to be involved in HOT. RESULTS AND CONCLUSIONS HOT was widely performed in all respiratory specialist hospitals, but only in 55% of clinics and in 67% of cardiovascular specialist hospitals. Among the total number of patients given HOT, the rate of patients with heart failure was 15%, 80% of whom had left-sided heart failure. This value was five times higher than that reported in a nationwide investigation in Japan. Since patients with advanced heart failure were highly comorbid with sleep-disordered breathing (SDB), non-invasive ventilation with continuous positive airway pressure (CPAP) instead of HOT was frequently given to these patients as first-line therapy. Checkups cooperation appeared relatively close among respiratory specialist hospitals, but not between cardiovascular specialist hospitals and district clinics.

Abstract
Few reports describe the features of 2009 pandemic influenza A(H1N1) pneumonia in children. We retrospectively reviewed 21 consecutive children admitted to hospital from September to October 2009 in the Tokyo region. The diagnosis of 2009 pandemic influenza A(H1N1) virus infection was based on positive results of real-time RT-PCR or rapid influenza antigen test. All patients were hospitalised for pneumonia with respiratory failure and severe hypoxia. The median interval from onset of influenza symptoms to admission was 14 hours (range: 5-72 hours) and the median interval from the onset of fever (≥38 degrees C) to hospitalisation was 8.5 hours (range: 0-36 hours). All patients required oxygen inhalation. Four patients required mechanical ventilation. Chest radiography revealed patchy infiltration or atelectasis in all patients. Antiviral agents and antibiotics were administrated to all patients. Antiviral agents were administered to 20 patients within 48 hours of influenza symptom onset. No deaths occurred during the study period. Paediatric patients with this pneumonia showed rapid aggravation of dyspnoea and hypoxia after the onset of influenza symptoms.

Abstract
STUDY OBJECTIVES Recent evidence has suggested that low socioeconomic status (SES), race, prematurity, and maternal smoking during pregnancy are associated with childhood sleep disordered breathing (SDB). We investigated (1) the association of SDB with a wide range of risk factors, including prenatal and perinatal complications; (2) the association of these complications with SES and race; and (3) the association of SDB with developmental milestones. METHODS Six hundred thirteen school-aged children (105 clinically referred and 508 community control subjects) underwent overnight polysomnography and had a complete history and physical examination. A comprehensive child development questionnaire was completed by a parent. We compared clinically referred children with SDB to population-based control children without SDB from The Penn State Children's Cohort. RESULTS Maternal smoking during pregnancy; maternal age and weight gain during pregnancy; prenatal complications, such as maternal high blood pressure and gestational diabetes; perinatal complications related to prematurity; delayed motor milestones; race and SES were significantly associated with the presence of childhood SDB. Most of the risk factors became nonsignificant when analyses controlled for race and SES. Delayed motor milestones remained significantly associated with SDB after controlling for race and SES. CONCLUSION These data suggest that there is a significant association between children who experience prenatal or perinatal distress and the development of moderate to severe childhood SDB. SES and race may be mediating the impact on SDB through increased prenatal and perinatal risks. The significant delay in motor milestones suggests that prenatal and perinatal distress may result in neurologic insult, which could influence the development of SDB in later childhood.

Abstract
RATIONALE Home oxygen is the most expensive equipment item that Medicare purchases ($1.7 billion/year). OBJECTIVES To assess geographic differences in supplemental oxygen use. METHODS Retrospective cohort analysis of oxygen claims for a 20% random sample of Medicare patients hospitalized for obstructive lung disease in 1999 and alive at the end of 2000. MEASUREMENTS AND MAIN RESULTS While 33.7% of the 34,916 hospitalized patients used supplemental oxygen, there was more than a 4-fold difference between states and a greater than 6-fold difference between hospital referral regions with high/low utilization. Rocky Mountain States and Alaska had the highest utilization, while the District of Columbia and Louisiana had the lowest utilization. After adjusting for patient characteristics and elevation, high-utilization communities included low-lying areas in California, Florida, Michigan, Missouri, and Washington. Patients who were younger, male, white, and who had more comorbidities, more hospital admissions, and lived at higher altitudes and in areas of greater income also had higher odds of using supplemental oxygen. Residing in rural areas was associated with higher unadjusted oxygen use rates. After adjustment, patients living in large rural areas had higher odds of using oxygen than patients living in urban areas or in small rural areas. CONCLUSIONS There is significant geographic variation in supplemental oxygen use, even after controlling for patient and contextual factors. The Centers for Medicare & Medicaid Services should examine these issues further and enact changes that ensure patient health and fiscal responsibility.

Abstract
OBJECTIVE To describe how intensive care nurses manage the administration of supplemental oxygen to patients during the first 24 hours after cardiac surgery. METHODS A retrospective audit was conducted of the medical records of 245 adult patients who underwent cardiac surgery between 1 January 2005 and 31 May 2008 in an Australian metropolitan hospital. Physiological data (oxygen saturation measured by pulse oximetry and respiratory rate) and intensive care unit management data (oxygen delivery device, oxygen flow rate and duration of mechanical ventilation) were collected at hourly intervals over the first 24 hours of ICU care. RESULTS Of the 245 patients whose records were audited, 185 were male; mean age was 70 years (SD, 10), and mean APACHE II score was 17.5 (SD, 5.14). Almost half the patients (122, 49.8%) were extubated within 8 hours of ICU admission. The most common oxygen delivery device used immediately after extubation was the simple face mask (214 patients, 87%). Following extubation, patients received supplemental oxygen via, on average, two different delivery devices (range, 1-3), and had the delivery device changed an average of 1.38 times (range, 0-6) during the 24 hours studied. Twenty-two patients (9%) received non-invasive ventilation or high-flow oxygen therapy, and 16 (7%) experienced one or more episode of hypoxaemia during mechanical ventilation. A total of 148 patients (60%) experienced one or more episodes of low oxygenation or abnormal respiratory rate during the first 24 hours of ICU care despite receiving supplemental oxygen. CONCLUSION These findings suggest that the ICU environment does not protect cardiac surgical patients from suboptimal oxygen delivery, and highlights the need for strategies to prompt the early initiation of interventions aimed at optimising blood oxygen levels in cardiac surgical patients in the ICU.

Abstract
BACKGROUND Studies of planned home births attended by registered midwives have been limited by incomplete data, nonrepresentative sampling, inadequate statistical power and the inability to exclude unplanned home births. We compared the outcomes of planned home births attended by midwives with those of planned hospital births attended by midwives or physicians. METHODS We included all planned home births attended by registered midwives from Jan. 1, 2000, to Dec. 31, 2004, in British Columbia, Canada (n = 2889), and all planned hospital births meeting the eligibility requirements for home birth that were attended by the same cohort of midwives (n = 4752). We also included a matched sample of physician-attended planned hospital births (n = 5331). The primary outcome measure was perinatal mortality; secondary outcomes were obstetric interventions and adverse maternal and neonatal outcomes. RESULTS The rate of perinatal death per 1000 births was 0.35 (95% confidence interval [CI] 0.00-1.03) in the group of planned home births; the rate in the group of planned hospital births was 0.57 (95% CI 0.00-1.43) among women attended by a midwife and 0.64 (95% CI 0.00-1.56) among those attended by a physician. Women in the planned home-birth group were significantly less likely than those who planned a midwife-attended hospital birth to have obstetric interventions (e.g., electronic fetal monitoring, relative risk [RR] 0.32, 95% CI 0.29-0.36; assisted vaginal delivery, RR 0.41, 95% 0.33-0.52) or adverse maternal outcomes (e.g., third- or fourth-degree perineal tear, RR 0.41, 95% CI 0.28-0.59; postpartum hemorrhage, RR 0.62, 95% CI 0.49-0.77). The findings were similar in the comparison with physician-assisted hospital births. Newborns in the home-birth group were less likely than those in the midwife-attended hospital-birth group to require resuscitation at birth (RR 0.23, 95% CI 0.14-0.37) or oxygen therapy beyond 24 hours (RR 0.37, 95% CI 0.24-0.59). The findings were similar in the comparison with newborns in the physician-assisted hospital births; in addition, newborns in the home-birth group were less likely to have meconium aspiration (RR 0.45, 95% CI 0.21-0.93) and more likely to be admitted to hospital or readmitted if born in hospital (RR 1.39, 95% CI 1.09-1.85). INTERPRETATION Planned home birth attended by a registered midwife was associated with very low and comparable rates of perinatal death and reduced rates of obstetric interventions and other adverse perinatal outcomes compared with planned hospital birth attended by a midwife or physician.

Abstract
SETTING Health facilities in The Gambia, West Africa. OBJECTIVES Oxygen treatment is vital in pneumonia, the leading cause of death in children globally. There are shortages of oxygen in developing countries, but little information is available on the extent of the problem. We assessed national oxygen availability and use in The Gambia, a sub-Saharan African country. METHODS A government-led team visited 12 health facilities in The Gambia. A modified World Health Organization assessment tool was used to determine oxygen requirements, current provision and capacity to support effective oxygen use. RESULTS Eleven of the 12 facilities managed severe pneumonia. Oxygen was reliable in three facilities. Requirement and supply were often mismatched. Both oxygen concentrators and oxygen cylinders were used. Suboptimal electricity and maintenance made using concentrators difficult, while logistical problems and cost hampered cylinder use. Children were usually triaged by trained nurses who reported lack of training in oxygen use. Oxygen was given typically by nasal prongs; pulse oximetry was available in two facilities. CONCLUSIONS National data showed that oxygen availability did not meet needs in most Gambian health facilities. Remedial options must be carefully assessed for real costs, reliability and site-by-site usability. Training is needed to support oxygen use and equipment maintenance.

Abstract
BACKGROUND Chronic lung disease (CLD) remains a major problem in neonatal intensive care units. Persistent inflammation in the lungs is the most likely underlying pathogenesis. Corticosteroids have been used to either prevent or treat CLD because of their potent anti-inflammatory effects. OBJECTIVES To determine if postnatal corticosteroid treatment is of benefit in the prevention of chronic lung disease (CLD) in preterm infants. This review examines the outcome of trials where preterm infants at risk of CLD were given postnatal corticosteroids within the first seven days of life. SEARCH STRATEGY Randomised controlled trials (RCTs) of postnatal corticosteroid therapy were sought from the Cochrane Controlled Trials Register, MEDLINE (1966 - May 2008), hand searching paediatric and perinatal journals, examining previous review articles and information received from practising neonatologists. Authors of all studies were contacted, where possible, to confirm details of reported follow-up studies, or to obtain any information about long-term follow-up where none had been reported. SELECTION CRITERIA Randomised controlled trials of postnatal corticosteroid treatment within the first 7 days of life (early) in high risk preterm infants were selected for this review. Most studies evaluated the use of dexamethasone but we also included studies that assessed hydrocortisone, even if it was used to manage hypotension. DATA COLLECTION AND ANALYSIS Data regarding clinical outcomes including mortality, CLD (including late rescue with corticosteroids, and need for home oxygen therapy), death or CLD, failure to extubate, complications during the primary hospitalisation (including infection, hyperglycaemia, hypertension, pulmonary air leak, patent ductus arteriosus (PDA), severe intraventricular haemorrhage (IVH), periventricular leucomalacia (PVL), necrotising enterocolitis (NEC), gastrointestinal bleeding, intestinal perforation, severe retinopathy of prematurity (ROP), and long-term outcome (including blindness, deafness, cerebral palsy and major neurosensory disability) were abstracted and analysed using RevMan 5. MAIN RESULTS Twenty-eight RCTs enrolling a total of 3740 participants were eligible for inclusion in this review. A meta-analysis of these trials demonstrated significant benefits as regards earlier extubation and decreased risks of CLD at both 28 days and 36 weeks' postmenstrual age (PMA), death or CLD at 28 days and 36 weeks' PMA, PDA and ROP, including severe ROP. There were no significant differences in the rates of neonatal or subsequent mortality, infection, severe IVH, PVL, NEC or pulmonary haemorrhage. Gastrointestinal bleeding and intestinal perforation were important adverse effects and the risks of hyperglycaemia, hypertension, hypertrophic cardiomyopathy and growth failure were also increased. In the twelve trials that reported late outcomes, several adverse neurological effects were found at follow-up examinations including developmental delay (not defined), cerebral palsy and abnormal neurological examination. However, major neurosensory disability was not significantly increased, either overall in the seven studies where this outcome could be determined, or in the two individual studies where the rates of cerebral palsy or abnormal neurological examination were significantly increased. Moreover, the rates of the combined outcomes of death or cerebral palsy, or of death or major neurosensory disability were not significantly increased. Dexamethasone was the drug used in most studies (n = 20); only eight studies used hydrocortisone. In subgroup analyses by type of corticosteroid, most of the beneficial and harmful effects were attributable to dexamethasone; hydrocortisone had little effect on any outcomes except for an increase in intestinal perforation and a borderline reduction in PDA. AUTHORS' CONCLUSIONS The benefits of early postnatal corticosteroid treatment (</= 7 days), particularly dexamethasone, may not outweigh the known or potential adverse effects of this treatment. Although early corticosteroid treatment facilitates extubation and reduces the risk of chronic lung disease and patent ductus arteriosus, it causes short-term adverse effects including gastrointestinal bleeding, intestinal perforation, hyperglycaemia, hypertension, hypertrophic cardiomyopathy and growth failure. Long-term follow-up studies report an increased risk of abnormal neurological examination and cerebral palsy. However, the methodological quality of the studies determining long-term outcomes is limited in some cases; the surviving children have been assessed predominantly before school age, and no study has been sufficiently powered to detect important adverse long-term neurosensory outcomes. There is a compelling need for the long-term follow-up and reporting of late outcomes, especially neurological and developmental outcomes, among surviving infants who participated in all randomised trials of early postnatal corticosteroid treatment. Hydrocortisone in the doses and regimens used in the reported RCTs has few beneficial or harmful effects and cannot be recommended for prevention of CLD.

Abstract
INTRODUCTION Long-term oxygen therapy (LTOT) is the only treatment improving survival of patients with respiratory failure due to chronic obstructive pulmonary disease (COPD). Benefits of treatment depend mainly on daily duration of oxygen use. The aim of the study was to assess daily use of oxygen and to evaluate influencing factors. MATERIAL AND METHODS Consecutive patients qualified to LTOT were included. Eligibility for LTOT was based on the ATS//ERS guidelines. All patients were instructed to use oxygen from oxygen concentrator for 15 hours per day or more. Duration of oxygen therapy was verified every 4 weeks by visiting respiratory nurse using counter clock of oxygen concentrator. The nurses were also encouraging patients to breathe oxygen for at least 15 h/d. RESULTS Study group consisted of 30 patients (77% with COPD) aged 67+/-9 yrs, mean FEV, 46+/-18% pred., RV%TLC 64+/-16%, PaO2 50+/-6 mm Hg. Mean duration of oxygen therapy for the group was 12.5+/-4.6 h/d. Eleven (37%) subjects followed prescription during whole follow-up period (mean oxygen use 17.4+/-2.6 h/d). Mean oxygen use in the non-compliant group was 9.6+/-2.7 h/d. In COPD group compliant patients had significantly lower TLC (100+/-19% pred. v. 152+/-36% pred., p=0.001) and lower PaCO2 (38+/-6 mm Hg v. 47+/-8 mm Hg, p<0.05) when compared to the non-compliant group. During the first month of treatment 48% of patients were compliant. From the second month onward percentage of compliant patients fell to 30% and remained stable to the end of the study. Fourteen patients (47% complained of electricity consumption and 7 patients (23%) complained of the noise of working concentrator. Daily oxygen use in the latest group was significantly lower when compared to those who did not complain of the noise (9+/-3.7 h/d v. 13.5+/-4.4 h/d; p=0.02). CONCLUSIONS The best compliance to home oxygen therapy is observed at the beginning of treatment. Frequent home nurse visits do not improve compliance. We hypothesize that the use of other oxygen sources eg. liquid oxygen, that are silent and do not increase the cost of electricity, could improve compliance.

Abstract
BACKGROUND Bronchopulmonary dysplasia is associated with ventilation and oxygen treatment. This randomized trial investigated whether nasal continuous positive airway pressure (CPAP), rather than intubation and ventilation, shortly after birth would reduce the rate of death or bronchopulmonary dysplasia in very preterm infants. METHODS We randomly assigned 610 infants who were born at 25-to-28-weeks' gestation to CPAP or intubation and ventilation at 5 minutes after birth. We assessed outcomes at 28 days of age, at 36 weeks' gestational age, and before discharge. RESULTS At 36 weeks' gestational age, 33.9% of 307 infants who were assigned to receive CPAP had died or had bronchopulmonary dysplasia, as compared with 38.9% of 303 infants who were assigned to receive intubation (odds ratio favoring CPAP, 0.80; 95% confidence interval [CI], 0.58 to 1.12; P=0.19). At 28 days, there was a lower risk of death or need for oxygen therapy in the CPAP group than in the intubation group (odds ratio, 0.63; 95% CI, 0.46 to 0.88; P=0.006). There was little difference in overall mortality. In the CPAP group, 46% of infants were intubated during the first 5 days, and the use of surfactant was halved. The incidence of pneumothorax was 9% in the CPAP group, as compared with 3% in the intubation group (P<0.001). There were no other serious adverse events. The CPAP group had fewer days of ventilation. CONCLUSIONS In infants born at 25-to-28-weeks' gestation, early nasal CPAP did not significantly reduce the rate of death or bronchopulmonary dysplasia, as compared with intubation. Even though the CPAP group had more incidences of pneumothorax, fewer infants received oxygen at 28 days, and they had fewer days of ventilation.

Abstract
OBJECTIVES Respiratory syncytial virus is the single-most important cause of lower respiratory tract infections in children. Preterm birth and congenital heart disease are known risk factors for severe respiratory syncytial virus infections. Although Down syndrome is associated with a high risk of respiratory tract infections, little is known about the incidence of respiratory syncytial virus infections in this group. The aim of our study was to determine the incidence of respiratory syncytial virus lower respiratory tract infection-associated hospitalization among children with Down syndrome. PATIENTS AND METHODS We performed a retrospective observational study and a prospective nationwide birth-cohort study of children with Down syndrome. The retrospective cohort comprised 176 children with Down syndrome. A birth cohort of 219 children with Down syndrome was prospectively followed until 2 years of age. All 276 siblings of the birth cohort were used as controls. RESULTS Of the 395 patients with Down syndrome, 180 (45.6%) had a known risk factor for severe respiratory syncytial virus infections; 39 (9.9%) of these were hospitalized for respiratory syncytial virus lower respiratory tract infections. Two control children (0.7%) versus 9 term children with Down syndrome without congenital heart disease (7.6%) were hospitalized for respiratory syncytial virus lower respiratory tract infections. The median duration of hospitalization was 10 days; mechanical ventilation was required for 5 children (12.8%). CONCLUSIONS This is the first study, to our knowledge, to demonstrate that Down syndrome is a novel independent risk factor for severe respiratory syncytial virus lower respiratory tract infections. These findings should prompt studies to investigate possible mechanisms that underlie severe respiratory syncytial virus lower respiratory tract infections in children with Down syndrome. The effect of respiratory syncytial virus prophylaxis in this specific population needs to be established.

Abstract
We aimed to study trends in gender-related differences in incidence, and prevalence for long-term oxygen therapy due to chronic obstructive pulmonary disease. Another aim was to study survival after onset of oxygen therapy. Prospectively followed were 5689 Swedish patients, who were prescribed oxygen therapy because of chronic obstructive pulmonary disease from 1987 to 2000. The annual incidence of women starting oxygen therapy increased more rapidly than that in men. In 2000, 7.6 per 100,000 women started treatment compared with 7.1 in men. The frequency of ever smoking in Sweden in the age group receiving oxygen, i.e. age 65-84 years, was 36.4% in women and 65.0% in men, indicating that women ran a higher risk of developing an oxygen-requiring chronic hypoxaemia. An increase in women requiring oxygen therapy is predicted due to the increase in smoking frequency in young and middle-aged women and it is estimated that about 70% of Swedish patients on oxygen in 2026 will be women, with an estimated prevalence of 61 per 100,000. In conclusion, the incidence and prevalence for long-term oxygen therapy increases more rapidly among women than in men. This is probably due to the increased frequency of smoking in women compared with men and a higher susceptibility to develop severe hypoxaemia in women. The survival is better in women with long-term oxygen therapy than in men.

Abstract
OBJECTIVE To assess the use of domiciliary oxygen therapy (DOT) in Tasmania and the impact of a specialist oxygen clinic on service provision. DESIGN Retrospective observational study. PARTICIPANTS AND SETTING Patients prescribed government-funded DOT in Tasmania between December 2002 and April 2004. MAIN OUTCOME MEASURES Indications for DOT; usage, prescription, reassessment and costs of DOT; influence of a specialist-run oxygen clinic. RESULTS 490 patients were using DOT, an overall rate of 102 patients per 100 000 population (varying between regions from 95 to 116 per 100 000 population). Of 267 patients (54%) prescribed DOT during hospitalisation, only 72% met national guidelines for DOT at commencement. Chronic obstructive pulmonary disease (COPD) was the most common indication (48% of prescriptions). The median time to reassessment after prescription was 5.5 months. Median usage in patients with COPD was 18.3 hours per day. The average cost per patient was $1498 per year, but differed regionally in relation to costs of ambulatory supplies. The oxygen clinic in the north-west region substantially reduced oxygen prescriptions, improved compliance with guidelines, decreased time to first reassessment from 21 to 6.6 months, and produced major cost savings. CONCLUSIONS Prescription of DOT was often not in keeping with national guidelines. Reassessment was poor, despite more than half the patients being prescribed DOT as an inpatient. A dedicated oxygen clinic resulted in more appropriate prescription, decreased time to reassessment and a reduction in costs.

Abstract
BACKGROUND Rapid sequence induction (RSI) is the 'gold standard' technique for preventing aspiration of gastric contents during induction of anesthesia in unfasted patients. We conducted a survey to discover whether the conduct of RSI in children varies amongst anesthetists and if practice alters in relation to the time since training or degree of ongoing experience. METHODS Six hundred and fifteen questionnaires were sent to anesthetists in the south-west of England. RESULTS The response rate was 61%. Preoxygenation was utilized by 83% of anesthetists for infants whereas 94% preoxygenated schoolchildren, P < 0.001. Only 59% of respondents used cricoid pressure in infants, compared with 96% in schoolchildren, P < 0.001. Propofol was the induction agent of choice for all anesthetists, although thiopentone was used more in infants (35%) than schoolchildren (9%), P < 0.001. Suxamethonium was widely used in all children. All anesthetists intubated patients for pyloromyotomy, 50% using cricoid pressure. RSI was performed by 86% of anesthetists for appendicectomy, with consultants most likely to deviate from a standard RSI. Sixty percent of anesthetists intubated for manipulation of forearm, 72% performing an RSI, 53% intubated for scrotal exploration, but only 42% performed an RSI. CONCLUSIONS Classical RSI is used for children by most anesthetists in south-west England. RSI is modified for infants especially by more recently trained consultants. Suxamethonium is used less by consultant anesthetists. Whilst RSI is performed for appendicectomy there is a large variation in techniques for anesthetizing children for MUA and scrotal exploration which is independent of the grade of anesthetist.

Abstract
Persons utilizing long term oxygen therapy (LTOT) at home suffer from chronic obstructive pulmonary disease (COPD). Adherence to LTOT ranges from 45% to 70% and utilization of 15 hours per day is widely accepted as efficacious. Although studies have reviewed the level of patient adherence with LTOT, few have introduced or evaluated interventions. The paucity of information regarding patients following oxygen prescription is an enormous void that must be tackled to augment clinical effectiveness and cost containment for the long term. A research agenda for LTOT adherence is postulated to help connect treatment adherence variables and concepts with clinical outcomes and quality of life.

Abstract
AIMS To support a national approach to oxygen systems in Papua New Guinea, we conducted a study to document the incidence of hypoxaemia, its geographical distribution, epidemiological determinants and resource availability in several regions of the country. We also established baseline mortality rate data for all children admitted to five hospitals, for children with a diagnosis of pneumonia and for neonates to evaluate a future intervention. METHODS Data were collected prospectively from over 1300 hospital admissions in five hospitals in 2004. To establish the baseline case fatality rates, data on outcome were collected retrospectively over 3 years (2001-2003) for over 20,000 children admitted to five hospitals. RESULTS A total of 1313 admissions were studied prospectively in the five hospitals. Altogether, 384 (29.25%, 95% CI 26.8-31.8) had hypoxaemia, defined as SpO(2) <90%. The incidence of hypoxaemia was much greater in highland hospitals (40% of all admissions) than on the coast (10% of all admissions). This large difference in incidence persisted when the uniform definition of hypoxaemia was adjusted for altitude, and was largely because of differences in the incidence of acute respiratory tract infection. Oxygen was not available on the day of admission for 22% of children (range between hospitals, 3-38), including 13% of all children with hypoxaemia. Oxygen was less available in remote rural district hospitals than in provincial hospitals in regional towns. Clinical signs proposed by WHO as indicators for oxygen would have missed 29% of children with hypoxaemia and, if these clinical signs were used, 30% of children without hypoxaemia would have been considered in need of supplemental oxygen. CONCLUSIONS Based on this study, an approach to improving the detection of hypoxaemia and the availability of oxygen has been trialled in these five hospitals where a programme of clinical and technical training in the use and maintenance of pulse oximetry and oxygen concentrators has been introduced.

Abstract
INTRODUCTION Long-term domiciliary oxygen therapy (LTOT) is part to of pulmonary care system. Uniform qualification criteria and methods of follow-up for patients undergoing LTOT have been adopted. There are 63 LTOT centres located in Poland run by specialists in pulmonology. On the occasion of 20 years of LTOT in Poland, an analysis of its development, number of patients treated, diagnoses, survival and equipment was performed. MATERIAL AND METHODS Data were taken from structurized LTOT centres reports. RESULTS AND CONCLUSIONS A history of LTOT may be divided into 3 periods, steady grow in the years 1986-1991, stagnation between 1992-2000 and rapid grow in the last 3 years. On 01.01.2006 there was 2601 patients receiving LTOT therapy. The most common diagnosis was COPD (85%) followed by kyphoscolisis (5%), TB sequels (4.6%), IPF (3.6%) and other rare diseases. Treatment is reimbursed by the National Health System. Oxygen is administered via an oxygen concentrator. Due to insufficient resources from the NHS the needs for LTOT treatment are not fulfilled. There are 8.4 patients treated with LTOT per 100 000 people, with large regional differences ranging from 3.7 to 14.9/100 000. The most frequent cause of death in patients receiving LTOT treatment was exacerbation of respiratory failure (71.3%), followed by sudden death (5.1%), myocardial infarction or pulmonary embolism (4.4%), lung cancer (4%) and other or not known causes (15.2%). Survival in patients receiving LTOT treatment from the years 1986-1995 was rather short: 54.6% survived less than 3 years, 3-4 years survived 13.3%, 4-5 years 11.3% and more than 5 years survived 19.7% of treated patients.
