A pilot randomised control trial of a parent training intervention for pre-school children with autism. Preliminary findings and methodological challenges.

Few attempts have been made to conduct randomised control trials (RCTs) of interventions for pre-school children with autism. We report findings of a pilot RCT for a parent training intervention with a focus on the development of joint attention skills and joint action routines. Twenty-four children meeting ICD-10 criteria for childhood autism (mean age = 23 months) were identified using the CHAT screen and randomised to the parent training group or to local services only. A follow-up was conducted 12 months later (mean age = 35 months). There was some evidence that the parent training group made more progress in language development than the local services group. However, the present pilot study was compromised by several factors: a reliance on parental report to measure language, non-matching of the groups on initial IQ, and a lack of systematic checking regarding the implementation of the parent training intervention. Furthermore, three parents in the local services group commenced intensive, home-based behavioural intervention during the course of the study. The difficulties encountered in the conduct of RCTs for pre-school children with autism are discussed. Methodological challenges and strategies for future well-designed RCTs for autism interventions are highlighted.

Transabdominal amnioinfusion in preterm premature rupture of membranes: a randomised controlled trial.

OBJECTIVE: To evaluate the role of transabdominal amnioinfusion in improving the perinatal outcomes of pregnancies complicated by preterm premature rupture of membranes (pPROM). DESIGN: A randomised controlled trial. SETTING: A teaching hospital in Italy, obstetric unit. Population Women with singleton pregnancies complicated by pPROM, between 24 + 0 and 32 + 6 weeks of gestation. METHODS: Patients were randomised 24 hours after admission to our referral hospital, to expectant management with transabdominal amnioinfusion or expectant management only. MAIN OUTCOME MEASURES: The effects of transabdominal amnioinfusion on pPROM-delivery interval and on perinatal outcomes. RESULTS: Of the 65 women with pPROM 34 met the inclusion criteria. Seventeen women were assigned to amnioinfusion (the amnioinfusion group) and the other 17 to expectant management. Compared with the control group (median: 8 days; range: 3-14), the pPROM-delivery period was significantly longer in women who underwent amnioinfusion (median: 21 days; range: 15-29) (P < 0.05). Women with amnioinfusion were less likely to deliver within seven days since pPROM (RR: 0.18; range: 0.04-0.69 95% CI) or within two weeks (RR: 0.46; range: 0.21-1.02 95% CI). In the amnioinfusion group the neonatal survival was significantly higher at each gestational age (P < 0.01, Yates's correction for Log Rank Test) with a reduction in pulmonary hypoplasia. CONCLUSIONS: We demonstrated that compared with standard expectant management the treatment with transabdominal amnioinfusion after pPROM resulted in significant prolongation of pregnancy and better neonatal outcomes.

Effect of handwashing on child health: a randomised controlled trial.

BACKGROUND: More than 3.5 million children aged less than 5 years die from diarrhoea and acute lower respiratory-tract infection every year. We undertook a randomised controlled trial to assess the effect of handwashing promotion with soap on the incidence of acute respiratory infection, impetigo, and diarrhoea. METHODS: In adjoining squatter settlements in Karachi, Pakistan, we randomly assigned 25 neighbourhoods to handwashing promotion; 11 neighbourhoods (306 households) were randomised as controls. In neighbourhoods with handwashing promotion, 300 households each were assigned to antibacterial soap containing 1.2% triclocarban and to plain soap. Fieldworkers visited households weekly for 1 year to encourage handwashing by residents in soap households and to record symptoms in all households. Primary study outcomes were diarrhoea, impetigo, and acute respiratory-tract infections (ie, the number of new episodes of illness per person-weeks at risk). Pneumonia was defined according to the WHO clinical case definition. Analysis was by intention to treat. FINDINGS: Children younger than 5 years in households that received plain soap and handwashing promotion had a 50% lower incidence of pneumonia than controls (95% CI (-65% to -34%). Also compared with controls, children younger than 15 years in households with plain soap had a 53% lower incidence of diarrhoea (-65% to -41%) and a 34% lower incidence of impetigo (-52% to -16%). Incidence of disease did not differ significantly between households given plain soap compared with those given antibacterial soap. INTERPRETATION: Handwashing with soap prevents the two clinical syndromes that cause the largest number of childhood deaths globally-namely, diarrhoea and acute lower respiratory infections. Handwashing with daily bathing also prevents impetigo.

Effect on hip fractures of increased use of hip protectors in nursing homes: cluster randomised controlled trial.

OBJECTIVE: To assess the effects of an intervention programme designed to increase use of hip protectors in elderly people in nursing homes. DESIGN: Cluster randomised controlled trial with 18 months of follow up. SETTING: Nursing homes in Hamburg (25 clusters in intervention group; 24 in control group). PARTICIPANTS: Residents with a high risk of falling (459 in intervention group; 483 in control group). INTERVENTION: Single education session for nursing staff, who then educated residents; provision of three hip protectors per resident in intervention group. Usual care optimised by brief information to nursing staff about hip protectors and provision of two hip protectors per cluster for demonstration purposes. MAIN OUTCOME MEASURE: Incidence of hip fractures. RESULTS: Mean follow up was 15 months for the intervention group and 14 months for the control group. In total 167 residents in the intervention group and 207 in the control group died or moved away. There were 21 hip fractures in 21 (4.6%) residents in the intervention group and 42 hip fractures in 39 (8.1%) residents in the control group (relative risk 0.57, absolute risk difference -3.5%, 95% confidence interval -7.3% to 0.3%, P=0.072). After adjustment for the cluster randomisation the proportions of fallers who used a hip protector were 68% and 15% respectively (mean difference 53%, 38% to 67%, P=0.0001). There were 39 other fractures in the intervention group and 38 in the control group. CONCLUSION: The introduction of a structured education programme and the provision of free hip protectors in nursing homes increases the use of protectors and may reduce the number of hip fractures.

Treatment of menorrhagia during menstruation: randomised controlled trial of ethamsylate, mefenamic acid, and tranexamic acid.

OBJECTIVE: To compare the efficacy and acceptability of ethamsylate, mefenamic acid, and tranexamic acid for treating menorrhagia. DESIGN: Randomised controlled trial. SETTING: A university department of obstetrics and gynaecology. SUBJECTS: 76 women with dysfunctional uterine bleeding. INTERVENTIONS: Treatment for five days from day 1 of menses during three consecutive menstrual periods. 27 patients were randomised to take ethamsylate 500 mg six hourly, 23 patients to take mefenamic acid 500 mg eight hourly, and 26 patients to take tranexamic acid 1 g six hourly. MAIN OUTCOMES MEASURES: Menstrual loss measured by the alkaline haematin method in three control menstrual periods and three menstrual periods during treatment; duration of bleeding; patient's estimation of blood loss; sanitary towel usage; the occurrence of dysmenorrhoea; and unwanted events. RESULTS: Ethamsylate did not reduce mean menstrual blood loss whereas mefenamic acid reduced blood loss by 20% (mean blood loss 186 ml before treatment, 148 ml during treatment) and tranexamic acid reduced blood loss by 54% (mean blood loss 164 ml before treatment, 75 ml during treatment). Sanitary towel usage was significantly reduced in patients treated with mefenamic acid and tranexamic acid. CONCLUSIONS: Tranexamic acid given during menstruation is a safe and highly effective treatment for excessive bleeding. Patients with dysfunctional uterine bleeding should be offered medical treatment with tranexamic acid before a decision is made about surgery.

Oral versus vaginal misoprostol administered one hour before surgical termination of pregnancy: a randomised controlled trial.

OBJECTIVE: To assess the efficacy of oral and vaginal misoprostol as cervical priming agents administered 1 hour before first trimester surgical termination of pregnancy. DESIGN: A randomised controlled trial. SETTING: Chelsea and Westminster Hospital, London. POPULATION: Pregnant women of 10 weeks or less gestation attending the termination of pregnancy clinic. METHODS: Ninety eligible women were recruited to the study during September 2001 and September 2002. Women were randomised to one of the three groups: misoprostol administered orally (400 microg), misoprostol administered vaginally (800 microg) and standard care (no cervical priming agent) administered prior to surgical termination of pregnancy. Under general anaesthesia, and prior to the operation, a cervical tonometer was used to determine the main outcome measures. MAIN OUTCOME MEASURES: Baseline cervical dilatation and the cumulative force required to dilate the cervix from 3 to 9 mm. RESULTS: There was no significant difference in the mean baseline cervical dilation (P= 0.16) or the cumulative force required to dilate the cervix (P= 0.12) between the three randomised groups. CONCLUSION: No cervical priming effects were detectable with oral or vaginal misoprostol administered 1 hour before first trimester surgical termination of pregnancy.

Detection of malformations in chromosomally normal fetuses by routine ultrasound at 12 or 18 weeks of gestation-a randomised controlled trial in 39,572 pregnancies.

OBJECTIVE: To compare the antenatal detection rate of malformations in chromosomally normal fetuses between a strategy of offering one routine ultrasound examination at 12 gestational weeks (gws) and a strategy of offering one routine examination at 18 gws. DESIGN: Randomised controlled trial. SETTING: Multicentre trial including eight hospitals. POPULATION: A total of 39,572 unselected pregnant women. METHODS: Women were randomised either to one routine ultrasound scan at 12 (12-14) gws including nuchal translucency (NT) measurement or to one routine scan at 18 (15-22) gws. Anomaly screening was performed in both groups following a check-list. A repeat scan was offered in the 12-week scan group if the fetal anatomy could not be adequately seen at 12-14 gws or if NT was >or=3.5 mm in a fetus with normal or unknown chromosomes. MAIN OUTCOME MEASURES: Antenatal detection rate of malformed fetuses. RESULTS: The antenatal detection rate of fetuses with a major malformation was 38% (66/176) in the 12-week scan group and 47% (72/152) in the 18-week scan group (P= 0.06). The corresponding figures for detection at <22 gws were 30% (53/176) and 40% (61/152) (P= 0.07). In the 12-week scan group, 69% of fetuses with a lethal anomaly were detected at a scan at 12-14 gws. CONCLUSIONS: None of the two strategies for prenatal diagnosis is clearly superior to the other. The 12-week strategy has the advantage that most lethal malformations will be detected at <15 gws, enabling earlier pregnancy termination. The 18-week strategy seems to be associated with a slightly higher detection rate of major malformations, although the difference was not statistically significant.

Effects of remote, retroactive intercessory prayer on outcomes in patients with bloodstream infection: randomised controlled trial.

OBJECTIVE: To determine whether remote, retroactive intercessory prayer, said for a group of patients with a bloodstream infection, has an effect on outcomes. DESIGN: Double blind, parallel group, randomised controlled trial of a retroactive intervention. SETTING: University hospital. SUBJECTS: All 3393 adult patients whose bloodstream infection was detected at the hospital in 1990-6. INTERVENTION: In July 2000 patients were randomised to a control group and an intervention group. A remote, retroactive intercessory prayer was said for the well being and full recovery of the intervention group. MAIN OUTCOME MEASURES: Mortality in hospital, length of stay in hospital, and duration of fever. RESULTS: Mortality was 28.1% (475/1691) in the intervention group and 30.2% (514/1702) in the control group (P for difference=0.4). Length of stay in hospital and duration of fever were significantly shorter in the intervention group than in the control group (P=0.01 and P=0.04, respectively). CONCLUSION: Remote, retroactive intercessory prayer said for a group is associated with a shorter stay in hospital and shorter duration of fever in patients with a bloodstream infection and should be considered for use in clinical practice.

Prophylactic endoscopic sclerotherapy of oesophageal varices in liver cirrhosis. A multicentre prospective controlled randomised trial in Vienna.

The effect of prophylactic treatment of oesophageal varices by endoscopic injection sclerotherapy before the first episode of variceal haemorrhage was studied in patients with cirrhosis in a prospective, randomised and controlled multicentre trial. From February 1984 to March 1987 patients with liver cirrhosis and large varices (stage III-IV according to Paquet) were treated and followed up. The sample comprised 87 patients: 45 in the prophylactic treatment and 42 in the control group. After excluding drop outs, 41 patients were treated in each group. Twenty nine per cent of patients in the sclerotherapy group and 34% in the control group had a variceal haemorrhage during the period of observation. There was no significant difference in the distributions of the bleeding free intervals between the sclerotherapy and the control groups. During the follow up period 24% of patients in the sclerotherapy group and 46% in the control group died. The distribution of survival times indicates a tendency towards longer survival of patients with prophylactic sclerotherapy, particularly in those with alcoholic cirrhosis.

Randomised controlled trial of patient triggered and conventional fast rate ventilation in neonatal respiratory distress syndrome.

AIM: To compare patient triggered, with conventional fast rate, ventilation in a randomised controlled trial using the incidence of chronic lung disease as the primary outcome measure. METHODS: Three hundred and eighty six preterm infants with birthweights from 1000 to 2000 g, and requiring ventilation for respiratory distress syndrome within 24 hours of birth, were randomised to receive either conventional or trigger ventilation with the SLE 2000 ventilator. RESULTS: There were no significant differences in the incidence of chronic lung disease (28 day and 36 week definitions), death, pneumothorax, intraventricular haemorrhage, number of ventilator days, or length of oxygen dependency between groups. CONCLUSIONS: Patient triggered ventilation in preterm infants with respiratory distress syndrome is feasible. No significant differences, when compared with conventional fast rate ventilation in important medium and longer term outcome measures, were evident.

Cluster randomised controlled trial comparing the effectiveness and cost-effectiveness of two primary care interventions aimed at improving attendance for breast screening.

OBJECTIVES: To examine the effectiveness and cost-effectiveness of two interventions based in primary care aimed at increasing uptake of breast screening. SETTING: 24 General practices with low uptake in the second round of screening (below 60%) in north west London and the West Midlands, UK. Participants were all women registered with these practices and eligible for screening in the third round. METHODS: Pragmatic factorial cluster randomised controlled trial, with practices randomised to a systematic intervention (general practitioner letter), an opportunistic intervention (flag in women's notes prompting discussion by health professionals), neither intervention, or both. Outcome measures were attendance for screening 6 months after the practices had been screened and cost-effectiveness of the interventions. RESULTS: 6,133 Women were included: 1,721 control; 1,818 letter; 1,232 flag; 1,362 both interventions. Attendance data were obtained for 5,732 (93%) women. The two interventions independently increased breast screening uptake in a logistic regression model adjusted for clustering, with the flag (odds ratio (OR) 1.43, 95% confidence interval (95% CI) 1.14 to 1.79; p=0.0019) marginally more effective than the letter (OR 1.31, 95% CI 1.05 to 1.64; p=0.015). Health service costs per additional attendance were 26 pounds (letter) and 41 pounds (flag). CONCLUSIONS: Although both interventions increased attendance for breast screening, the letter was the more cost-effective. Any decision to implement both interventions rather than just the letter will depend on whether the additional (41 pounds) costs are judged worthwhile in terms of the gains in breast screening uptake.

Randomised controlled trial of two methods of weaning from high frequency positive pressure ventilation.

Forty preterm infants suffering from respiratory distress syndrome were entered into a randomised controlled trial to assess the importance of the length of inspiratory time during weaning from high frequency positive pressure ventilation (HFPPV). Two weaning regimes were compared: in one (group A) inspiratory time was limited to 0.5 seconds throughout weaning, in the other (group B) ventilator rate was reduced by increasing both inspiratory and expiratory time (inspiration:expiration ratio constant) until inspiratory time reached 1.0 seconds. At ventilator rates of 20 and 40 breaths/minute an acute comparison was made in all 40 infants of the two inspiratory times; despite the lower mean airway pressure associated with the shorter inspiratory time blood gases were maintained. There was no difference in the incidence of pneumothoraces or need for reventilation between the two regimens but infants in group A had a shorter duration of weaning. We conclude limitation of inspiratory time to 0.5 seconds during weaning from HFPPV is advantageous to preterm infants with respiratory distress syndrome.

Family and parenting interventions for conduct disorder and delinquency: a meta-analysis of randomised controlled trials.

AIMS: To determine whether family and parenting interventions benefit children and adolescents with conduct disorder and delinquency. METHODS: Meta-analysis of eight randomised controlled trials involving 749 children and adolescents (aged 10-17 years) with conduct disorder and/or delinquency. Criminality, academic performance, future employment, problem behaviour, family functioning, parental mental health, and peer relations were evaluated. RESULTS: Family and parenting interventions significantly reduced the time spent by juvenile delinquents in institutions (weighted mean difference 51.34 days). There was also a significant reduction in the risk of a juvenile delinquent being rearrested (relative risk 0.66) and in their rate of subsequent arrests at 1-3 years (standardised mean difference -0.56). CONCLUSIONS: The evidence suggests that family and parenting interventions for juvenile delinquents and their families have beneficial effects on reducing time spent in institutions and their criminal activity. In addition to the obvious benefit to the participant and their family, this may result in a cost saving for society.

Randomised controlled trial of specialist nurse intervention in heart failure.

OBJECTIVES: To determine whether specialist nurse intervention improves outcome in patients with chronic heart failure. DESIGN: Randomised controlled trial. SETTING: Acute medical admissions unit in a teaching hospital. PARTICIPANTS: 165 patients admitted with heart failure due to left ventricular systolic dysfunction. The intervention started before discharge and continued thereafter with home visits for up to 1 year. MAIN OUTCOME MEASURES: Time to first event analysis of death from all causes or readmission to hospital with worsening heart failure. RESULTS: 31 patients (37%) in the intervention group died or were readmitted with heart failure compared with 45 (53%) in the usual care group (hazard ratio=0.61, 95% confidence interval 0.33 to 0.96). Compared with usual care, patients in the intervention group had fewer readmissions for any reason (86 v 114, P=0.018), fewer admissions for heart failure (19 v 45, P<0.001) and spent fewer days in hospital for heart failure (mean 3.43 v 7.46 days, P=0.0051). CONCLUSIONS: Specially trained nurses can improve the outcome of patients admitted to hospital with heart failure.

Effects of community based nurses specialising in Parkinson's disease on health outcome and costs: randomised controlled trial.

OBJECTIVE: To determine the effects of community based nurses specialising in Parkinson's disease on health outcomes and healthcare costs. DESIGN: Two year randomised controlled trial. SETTING: 438 general practices in nine randomly selected health authority areas of England. PARTICIPANTS: 1859 patients with Parkinson's disease identified by the participating general practices. MAIN OUTCOME MEASURES: Survival, stand-up test, dot in square test, bone fracture, global health question, PDQ-39, Euroqol, and healthcare costs. RESULTS: After two years 315 (17.3%) patients had died, although mortality did not differ between those who were attended by nurse specialists and those receiving standard care from their general practitioner (hazard ratio for nurse group v control group 0.91, 95% confidence interval 0.73 to 1.13). No significant differences were found between the two groups for the stand-up test (odds ratio 1.15, 0.93 to 1.42) and dot in square score (difference -0.7, -3.25 to 1.84). Scores on the global health question were significantly better in patients attended by nurse specialists than in controls (difference -0.23, -0.4 to -0.06), but no difference was observed in the results of the PDQ-39 or Euroqol questionnaires. Direct costs for patient health care increased by an average of 2658 pounds sterling during the study, although not differentially between groups: the average increase was 266 pounds sterling lower among patients attended by a nurse specialist (-981 pounds sterling to 449 pounds sterling ). CONCLUSIONS: Nurse specialists in Parkinson's disease had little effect on the clinical condition of patients, but they did improve their patients' sense of wellbeing, with no increase in patients' healthcare costs.

A randomised controlled trial of management strategies for acute infective conjunctivitis in general practice.

OBJECTIVE: To assess different management strategies for acute infective conjunctivitis. DESIGN: Open, factorial, randomised controlled trial. SETTING: 30 general practices in southern England. PARTICIPANTS: 307 adults and children with acute infective conjunctivitis. INTERVENTION: One of three antibiotic prescribing strategies-immediate antibiotics (chloramphenicol eye drops; n = 104), no antibiotics (controls; n = 94), or delayed antibiotics (n = 109); a patient information leaflet or not; and an eye swab or not. MAIN OUTCOME MEASURES: Severity of symptoms on days 1-3 after consultation, duration of symptoms, and belief in the effectiveness of antibiotics for eye infections. RESULTS: Prescribing strategies did not affect the severity of symptoms but duration of moderate symptoms was less with antibiotics: no antibiotics (controls) 4.8 days, immediate antibiotics 3.3 days (risk ratio 0.7, 95% confidence interval 0.6 to 0.8), delayed antibiotics 3.9 days (0.8, 0.7 to 0.9). Compared with no initial offer of antibiotics, antibiotic use was higher in the immediate antibiotic group: controls 30%, immediate antibiotics 99% (odds ratio 185.4, 23.9 to 1439.2), delayed antibiotics 53% (2.9, 1.4 to 5.7), as was belief in the effectiveness of antibiotics: controls 47%, immediate antibiotics 67% (odds ratio 2.4, 1.1 to 5.0), delayed antibiotics 55% (1.4, 0.7 to 3.0), and intention to reattend for eye infections: controls 40%, immediate antibiotics 68% (3.2, 1.6 to 6.4), delayed antibiotics 41% (1.0, 0.5 to 2.0). A patient information leaflet or eye swab had no effect on the main outcomes. Reattendance within two weeks was less in the delayed compared with immediate antibiotic group: 0.3 (0.1 to 1.0) v 0.7 (0.3 to 1.6). CONCLUSIONS: Delayed prescribing of antibiotics is probably the most appropriate strategy for managing acute conjunctivitis in primary care. It reduces antibiotic use, shows no evidence of medicalisation, provides similar duration and severity of symptoms to immediate prescribing, and reduces reattendance for eye infections.

Meta-analysis of randomised controlled trials of the effectiveness of antiarrhythmic agents at promoting sinus rhythm in patients with atrial fibrillation.

OBJECTIVE: To conduct a meta-analysis of randomised controlled trials to estimate the effectiveness of antiarrhythmic drugs at promoting sinus rhythm in patients with atrial fibrillation. DESIGN: Articles were identified by using a comprehensive search of English language papers indexed in Medline from 1966 to August 2001. For the outcomes of sinus rhythm and death, a random effects model was used to model repeated assessments within a study at different time points. SETTING: Emergency departments and ambulatory clinics. PATIENTS: Patients with atrial fibrillation. INTERVENTIONS: Antiarrhythmic agents grouped according to their Vaughan-Williams class. MAIN OUTCOME MEASURES: Sinus rhythm and mortality. RESULTS: 91 articles met a priori criteria for inclusion in the analysis. Median duration of follow up was one day (range 0.04-1096, mean (SD) 46 (136) days). The median proportion of patients in sinus rhythm at follow up was 55% (range 0-100%) and 32% (range 0-90%) receiving active treatment and placebo, respectively. Median survival was 99% (range 55-100%) and 99% (range 55-100%). Compared with placebo, the following drug classes were associated with increased sinus rhythm at follow up: IA (treatment difference 21.5%, 95% confidence interval (CI) 16.3% to 26.8%); IC (treatment difference 33.1%, 95% CI 23.3% to 42.9%); and III (treatment difference 17.4%, 95% CI 11.5% to 23.3%). Class IC drugs were associated with increased sinus rhythm at follow up compared with class IV drugs (treatment difference 43.2%, 95% CI 11.5% to 75.0%). There was no significant difference in mortality between any drug classes. CONCLUSIONS: Class IA, IC, and III drugs are associated with increased sinus rhythm at follow up compared with placebo. It is unclear whether any antiarrhythmic drug class is associated with increased or decreased mortality.

Association of quality of life in old age in Britain with socioeconomic position: baseline data from a randomised controlled trial.

STUDY OBJECTIVE: To identify socioeconomic differentials in quality of life among older people and their explanatory factors. DESIGN: Baseline data from a cluster randomised controlled trial of the assessment and management of older people in primary care. Outcome measures were being in the worst quintile of scores for, respectively, the Philadelphia geriatric morale scale and four dimensions of functioning from the sickness impact profile (home management, mobility, self care, and social interaction). SETTING: 23 general practices in Britain. PARTICIPANTS: People aged 75 years and over on GP registers at the time of recruitment, excluding those in nursing homes or terminally ill. Of 9547 people eligible, 90% provided full information on quality of life and 6298 also did a brief assessment. RESULTS: The excess risk of poor quality of life for independent people renting rather than owning their home ranged from 27% for morale (95% CI 9% to 48%) to 62% for self care (95% CI 35% to 94%). Self reported health problems plus smoking and alcohol consumption accounted for half or more of the excess, depending on the outcome. Having a low socioeconomic position in middle age as well as in old age exacerbated the risks of poor outcomes. Among people living with someone other than spouse the excess risk from renting ranged from 24% (95% CI -10% to 70%) for poor home management to 93% (95% CI 30% to 180%) for poor morale. CONCLUSIONS: Older people retain the legacy of past socioeconomic position and are subject to current socioeconomic influences.
