Effect of a structured educational intervention on explanatory models of relatives of patients with schizophrenia: randomised controlled trial.

We examined the effect of a structured educational programme on explanatory models of illness among the relatives of people with schizophrenia, in a randomised controlled trial. Participants were assessed at baseline (n=100) and after 2 weeks (n=75) using a vignette from the Short Explanatory Model Interview. There was a reduction in non-biomedical causal explanatory models at follow-up among those who had completed the structured educational programme compared with the control group. There was no significant difference in non-biomedical treatment explanatory models between the two groups.

Telephone counselling as an adjunct to nicotine patches in smoking cessation: a randomised controlled trial.

OBJECTIVES: To investigate the effectiveness of telephone counselling as an adjunct to nicotine replacement therapy (NRT) by transdermal patch in smoking cessation. DESIGN: Randomised controlled trial. PARTICIPANTS AND SETTING: 854 smokers from New South Wales, aged 18 years and older, who had smoked at least 10 cigarettes per day for the past year and responded to newspaper advertisements between October 2001 and January 2002; the trial was conducted between October 2001 and August 2002. INTERVENTIONS: Random allocation to either NRT alone or NRT plus telephone counselling (5 sessions spaced according to a relapse-sensitive call schedule). MAIN OUTCOME MEASURES: Self-reported abstinence assessed by telephone questionnaires at 1, 2, 3 and 6 months: 28-day continuous abstinence at 3 and 6 months, and 90-day continuous abstinence at 6 months. RESULTS: 28-day continuous abstinence rates among participants receiving telephone counselling were significantly greater than among those not receiving telephone counselling at both 3 and 6 months (31.6% v 25.1%; P = 0.04 at 3 months; and 30.1% v 22.4%; P = 0.01 at 6 months). Similarly, 90-day continuous abstinence rates at 6 months were significantly greater for participants receiving counselling (26.7% v 18.6%; P = 0.004). CONCLUSION: Telephone counselling as an adjunct to NRT increases abstinence rates beyond the use of NRT alone.

Does the CONSORT checklist improve the quality of reports of randomised controlled trials? A systematic review.

OBJECTIVE: To determine whether the adoption of the CONSORT checklist is associated with improvement in the quality of reporting of randomised controlled trials (RCTs). DATA SOURCES: MEDLINE, EMBASE, Cochrane CENTRAL, and reference lists of included studies and of experts were searched to identify eligible studies published between 1996 and 2005. STUDY SELECTION: Studies were eligible if they (a) compared CONSORT-adopting and non-adopting journals after the publication of CONSORT, (b) compared CONSORT adopters before and after publication of CONSORT, or (c) a combination of (a) and (b). Outcomes examined included reports for any of the 22 items on the CONSORT checklist or overall trial quality. DATA SYNTHESIS: 1128 studies were retrieved, of which 248 were considered possibly relevant. Eight studies were included in the review. CONSORT adopters had significantly better reporting of the method of sequence generation (risk ratio [RR], 1.67; 95% CI, 1.19-2.33), allocation concealment (RR, 1.66; 95% CI, 1.37-2.00) and overall number of CONSORT items than non-adopters (standardised mean difference, 0.83; 95% CI, 0.46-1.19). CONSORT adoption had less effect on reporting of participant flow (RR, 1.14; 95% CI, 0.89-1.46) and blinding of participants (RR, 1.09; 95% CI, 0.84-1.43) or data analysts (RR, 5.44; 95% CI, 0.73-36.87). In studies examining CONSORT-adopting journals before and after the publication of CONSORT, description of the method of sequence generation (RR, 2.78; 95% CI, 1.78-4.33), participant flow (RR, 8.06; 95% CI, 4.10-15.83), and total CONSORT items (standardised mean difference, 3.67 items; 95% CI, 2.09-5.25) were improved after adoption of CONSORT by the journal. CONCLUSIONS: Journal adoption of CONSORT is associated with improved reporting of RCTs.

The use of a structured form during urology out-patient consultations -- a randomised controlled trial.

OBJECTIVES: To compare the completeness of documentation in the medical record using a structured form (SF) versus a traditional medical record (TMR). METHODS: Randomised controlled trial comparing the use of SF and TMR in urology out-patient clinics for documentation of 15 items of clinical information, time taken to complete and acceptability to clinicians assessed by a self-completion questionnaire.in a teaching and district general hospitals. RESULTS: Four hundred new urology patient consultations, 11 clinicians. Completeness of information was compared between groups based on the medical record alone (SF vs. TMR), medical record plus letter to GP and letter alone. SFs were significantly (p<0.0001) more complete than TMRs for the majority of the items in all three groups. There was no significant difference in the time taken to document information using either type of record. The clinicians generally found the SF acceptable for routine use. CONCLUSIONS: Structured forms significantly improved the completeness of documentation for new out-patient consultations in urology.

Meta-analysis of randomised controlled trials comparing latanoprost with timolol in the treatment of patients with open angle glaucoma or ocular hypertension.

AIM: To evaluate the comparative efficacy and tolerance of latanoprost versus timolol through a meta-analysis of randomised controlled trials (RCTs). METHODS: Systematic retrieval of RCTs of latanoprost versus timolol to allow pooling of results from head to head comparison studies. Quality of trials was assessed based on randomisation, masking, and withdrawal. Sensitivity analyses were used to estimate the effects of quality of study on outcomes. The data sources were Medline, Embase, Scientific Citation Index, Merck Glaucoma, and Pharmacia and Upjohn ophthalmology databases. There were 1256 patients with open angle glaucoma or ocular hypertension reported in 11 trials of latanoprost versus timolol. The main outcome measures were (i) percentage intraocular pressure (IOP) reduction for efficacy; (ii) relative risk, risk difference, and number needed to harm for side effects such as hyperaemia, conjunctivitis, increased pigmentation, hypotension, and bradycardia expressed as dichotomous outcomes; and (iii) reduction in systemic blood pressure and heart rate as side effects. RESULTS: Both 0.005% latanoprost once daily and 0.5% timolol twice daily reduced IOP. The percentage reductions in IOP from baseline (mean (SE)) produced by latanoprost and timolol were 30.2 (2.3) and 26.9 (3.4) at 3 months. The difference in IOP reduction between the two treatments were 5.0 (95% confidence intervals 2.8, 7.3). However, latanoprost caused iris pigmentation in more patients than timolol (relative risk = 8.01, 95% confidence intervals 1.87, 34.30). The 2 year risk with latanoprost reached 18% (51/277). Hyperaemia was also more often observed with latanoprost (relative risk =2.20, 95% confidence intervals 1.33, 3.64). Timolol caused a significant reduction in heart rate of 4 beats/minute (95% confidence interval 2, 6). CONCLUSION: This meta-analysis suggests that latanoprost is more effective than timolol in lowering IOP. However, it often causes iris pigmentation. While current evidence suggests that this pigmentation is benign, careful lifetime evaluation of patients is still justified.

How long should urinary bladder catheterisation be continued after vaginal prolapse surgery? A randomised controlled trial comparing short term versus long term catheterisation after vaginal prolapse surgery.

OBJECTIVE: To determine whether prolonged urinary bladder catheterisation after vaginal prolapse surgery is advantageous. DESIGN: Randomised controlled trial. SETTING: A large training hospital in the Netherlands. POPULATION: Patients undergoing anterior colporrhaphy. METHODS: One hundred patients were included. Patients were randomised into two groups. In one group (n= 50), a transurethral catheter was in place for four days post-operatively and removed on the fifth post-operative day. In the other group (n= 50), catheterisation was not prolonged and the catheter was removed the morning after surgery. Residual volumes after removal of the catheter were measured by ultrasound scanning. Where residual volumes of >200 mL were found the patient was recatheterised for three more days. Urinary cultures were taken before removal of the catheter. Six patients were excluded: four in the standard prolonged catheterisation group and two in the not prolonged catheterisation group. MAIN OUTCOME MEASURES: Need for recatheterisation, urinary tract infection, mean duration of catheterisation and hospital stay. RESULTS: Residual volumes exceeding 200 mL and need for recatheterisation occurred in 9% in the standard prolonged catheterisation group versus 40% of patients in the not prolonged catheterisation group (OR 0.15, 95% CI 0.045-0.47). Positive urine cultures were found in 40% of cases in the standard prolonged catheterisation group compared with 4% in the not prolonged catheterisation group (OR 15, 95% CI 3.2-68.6). Mean duration of catheterisation was 5.3 days in the standard prolonged catheterisation group and 2.3 days in the not prolonged catheterisation group (P < 0.001). Mean duration of hospitalisation was 7 days in the standard prolonged catheterisation group and 5.7 days in the not prolonged group (P < 0.001). CONCLUSION: The disadvantages of prolonged catheterisation outweigh the advantages, therefore, removal of the catheter on the morning after surgery may be preferable and longer term catheterisation should only be undertaken where there are specific indications.

Loop diathermy excision compared with cervical laser vaporisation for the treatment of intraepithelial neoplasia: a randomised controlled trial.

OBJECTIVE: To determine whether loop diathermy excision of the transformation zone and laser vaporisation are equally effective in the treatment of cervical intraepithelial neoplasia. DESIGN: Randomised controlled trial. POPULATION: Women referred for evaluation of cytological abnormality who were considered suitable for outpatient local destructive treatment. SETTING: Seven colposcopy units in the North West Region. METHODS: Loop diathermy excision of the transformation zone and laser vaporisation. MAIN OUTCOME MEASURE: Smear reported as moderate dyskariosis or worse following treatment. RESULTS: Of 289 women randomised, 285 had one or more smears following treatment. Women were more likely to have a smear reported as moderate dyskariosis or worse following laser vaporisation [hazard ratio 3.01 (95% CI 1.27 to 7.12)]. The cumulative risk of a smear reported as moderate dyskariosis or worse was 6.0% at six months and 12.1% at three years in those allocated laser vaporisation, and 2.0% at six months, and 3.3% at three years in those allocated loop diathermy excision of the transformation zone. CONCLUSIONS: Loop diathermy excision is a more effective treatment of cervical intraepithelial neoplasia than laser vaporisation.

Immediate and delayed pushing in the second stage of labour for nulliparous women with epidural analgesia: a randomised controlled trial.

OBJECTIVE: To test the hypothesis that a policy of delaying active pushing in nulliparous women with epidural analgesia in labour reduces operative vaginal deliveries. DESIGN: A randomised controlled trial. SETTING: The delivery suite at Leeds General Infirmary. SAMPLE: One hundred and thirty-five nulliparous women with an effective epidural in labour. METHODS: The women were randomised to early pushing (commencement of pushing within one hour of the diagnosis of full dilatation) or delayed pushing (delaying pushing for a maximum of three hours from the time of diagnosis of full dilatation, unless the vertex was visible at the introitus sooner. MAIN OUTCOME MEASURE: Rate of instrumental vaginal delivery. RESULTS: There was a nonsignificantly increased rate of instrumental vaginal delivery with early pushing (odds ratio 1.31, 95% CI 0.62-2.78). No adverse effects were noted. CONCLUSION: Although delayed pushing was associated with fewer instrumental vaginal deliveries, the size of the effect may have occurred by chance and the evidence does not, at present, justify a general recommendation towards either early or delayed pushing.

Size and quality of randomised controlled trials in head injury: review of published studies.

OBJECTIVE: To assess whether trials in head injury are large enough to avoid moderate random errors and designed to avoid moderate biases. DESIGN: All randomised controlled trials on the treatment and rehabilitation of patients with head injury published before December 1998 were surveyed. Trials were identified from electronic databases, by hand searching journals and conference proceedings, and by contacting researchers. Data were extracted on the number of participants, quality of concealment of allocation, use of blinding, loss to follow up, and types of participants, interventions, and outcome measures. RESULTS: 279 reports were identified, containing information on 208 separate trials. The average number of participants per trial was 82, with no evidence of increasing size over time. The total number of randomised participants in the 203 trials in which size was reported was 16 613. No trials were large enough to detect reliably a 5% absolute reduction in the risk of death or disability, and only 4% were large enough to detect an absolute reduction of 10%. Concealment of allocation was adequate in 22 and inadequate or unclear in 25 of the 47 (23%) in which it was reported. Of 126 trials assessing disability, 111 reported the number of patients followed up, and average loss to follow up was 19%. Of trials measuring disability, 26 (21%) reported that outcome assessors were blinded. CONCLUSIONS: Randomised trials in head injury are too small and poorly designed to detect or refute reliably moderate but clinically important benefits or hazards of treatment. Limited funding for injury research and unfamiliarity with issues of consent may have been important obstacles.

Randomised, controlled trial of alternating pressure mattresses compared with alternating pressure overlays for the prevention of pressure ulcers: PRESSURE (pressure relieving support surfaces) trial.

OBJECTIVE: To compare whether differences exist between alternating pressure overlays and alternating pressure mattresses in the development of new pressure ulcers, healing of existing pressure ulcers, and patient acceptability. DESIGN: Pragmatic, open, multicentre, randomised controlled trial. SETTING: 11 hospitals in six NHS trusts. PARTICIPANTS: 1972 people admitted to hospital as acute or elective patients. INTERVENTIONS: Participants were randomised to an alternating pressure mattress (n = 982) or an alternating pressure overlay (n = 990). MAIN OUTCOME MEASURES: The proportion of participants developing a new pressure ulcer of grade 2 or worse; time to development of new pressure ulcers; proportions of participants developing a new ulcer within 30 days; healing of existing pressure ulcers; and patient acceptability. RESULTS: Intention to treat analysis found no difference in the proportions of participants developing a new pressure ulcer of grade 2 or worse (10.7% overlay patients, 10.3% mattress patients; difference 0.4%, 95% confidence interval--2.3% to 3.1%, P = 0.75). More overlay patients requested change owing to dissatisfaction (23.3%) than mattress patients (18.9%, P = 0.02). CONCLUSION: No difference was found between alternating pressure mattresses and alternating pressure overlays in the proportion of people who develop a pressure ulcer. TRIAL REGISTRATION: ISRCTN 78646179.

Randomised controlled trial of ultrasonography in diagnosis of acute appendicitis, incorporating the Alvarado score.

OBJECTIVES: To determine whether diagnosis by graded compression ultrasonography improves clinical outcomes for patients with suspected appendicitis. DESIGN: A randomised controlled trial comparing clinical diagnosis (control) with a diagnostic protocol incorporating ultrasonography and the Alvarado score (intervention group). SETTING: Single tertiary referral centre. PARTICIPANTS: 302 patients (age 5-82 years) referred to the surgical service with suspected appendicitis. 160 patients were randomised to the intervention group, of whom 129 underwent ultrasonography. Ultrasonography was omitted for patients with extreme Alvarado scores (1-3, 9, or 10) unless requested by the admitting surgical team. MAIN OUTCOME MEASURES: Time to operation, duration of hospital stay, and adverse outcomes, including non-therapeutic operations and delayed treatment in association with perforation. RESULTS: Sensitivity and specificity of ultrasonography were measured at 94. 7% and 88.9%, respectively. Patients in the intervention group who underwent therapeutic operation had a significantly shorter mean time to operation than patients in the control group (7.0 v 10.2 hours, P=0.016). There were no differences between groups in mean duration of hospital stay (53.4 v 54.5 hours, P=0.84), proportion of patients undergoing a non-therapeutic operation (9% v 11%, P=0.59) or delayed treatment in association with perforation (3% v 1%, P=0.45). CONCLUSION: Graded compression ultrasonography is an accurate procedure that leads to the prompt diagnosis and early treatment of many cases of appendicitis, although it does not prevent adverse outcomes or reduce length of hospital stay.

Randomised controlled trial of rehabilitation in chronic respiratory disability.

A randomised controlled study of the effects of exercise training in 39 patients with chronic respiratory disability was performed. Exercise training began with six weeks in a rehabilitation centre and was continued at home. The original control group attended the rehabilitation centre after the controlled part of the study. The treated group experienced subjective benefit from rehabilitation. The 12-minute walking distance increased on average from 523 m to 643 m in the treatment group and from 564 m to 607 m in the control group. The treatment effect of 77 m (SE 33 m) was significant at the 5% level. Treadmill exercise performance changed little and resting lung function was unaltered after rehabilitation. The treatment group maintained most of their improvement seven months later and the original control subjects improved after their rehabilitation. The study confirms the beneficial effects of exercise training in the chronically breathless and it suggests that the 12-minute walking distance is a useful index of changes in everyday exercise tolerance.

Behaviourally informed text message reminders to increase cervical screening attendance in people with severe mental illness: the OPTIMISE pilot randomised controlled trial.

OBJECTIVES: This study assessed the feasibility of both the delivery and evaluation of 'enhanced' (behaviourally informed) text message reminders containing links to existing co-designed resources supporting decision-making for people with severe mental illness (SMI) regarding attendance of cervical screening. DESIGN: A pilot randomised controlled trial (RCT). SETTING: 13 General Practice (GP) practices in London were recruited. PARTICIPANTS: GP practices identified people with SMI aged 24-64 years who were overdue cervical screening. Target sample size was 120 participants (60 per arm) based on existing guidance for pilot trials. INTERVENTION: In March 2025, participants were randomised (1:1) to receive either the enhanced (intervention) or the standard (control) SMS reminder. PRIMARY AND SECONDARY OUTCOME MEASURES: 18 weeks later, feasibility outcomes were collected (primary outcomes) and data analysis for a definitive RCT was rehearsed (secondary outcome). RESULTS: Of the 150 participants across 13 GP practices that were randomised (n=75 per arm), 132 (88%) texts delivered (intervention n=64/75 (85%), control n=68/75 (91%)). 10 practices (76.9%) provided follow-up data for 102 participants (intervention n=50, control n=52). Five participants (intervention n=4, control n=1) attended screening within the trial period. Participant survey response rate was low (9/132 (7%), intervention n=5, control n=4). Both SMS messages were low cost, with the intervention SMS a 50% higher cost to deliver (7.5p vs 5p per SMS). Primary feasibility measures of recruitment rate of GP practices (27%), retention of GP practices (77%) and participants (100%), SMS delivery (88%) and data completeness (64%) indicated viability, although survey response rate (7%) did not. CONCLUSIONS: Achieving adequate recruitment and retention, data completeness and comparable groups is viable with some amendments, although an alternative method is required to assess fidelity. Behaviourally informed SMS reminders are feasible to deliver to people with SMI, although it is uncertain if the extra resources are accessed and used. With changes to data collection, a definitive trial could be feasible. Given the low observed cervical screening attendance, additional intervention is needed for this group. TRIAL REGISTRATION NUMBER: ISRCTN12558681.

Randomised controlled trial of a reduced-visits programme of antenatal care in Harare, Zimbabwe.

BACKGROUND: Many of the individual components of antenatal care have been studied in randomised controlled trials, but few studies have compared whole programmes of antenatal care. Our aim was to test the hypothesis that a new programme of antenatal care with fewer goal-oriented visits would give an equivalent or better result in the outcomes associated with pregnancy and delivery. METHODS: In a randomised clinical trial in Harare, Zimbabwe, we compared a new programme of antenatal care with the standard programme. The new programme consisted of fewer but more objectively oriented visits and fewer procedures per visit. Seven primary care clinics were randomly assigned to the two programmes-three to the standard programme and four to the new programme. FINDINGS: Over a 2-year period, 15,994 women were recruited into the study at the time they booked antenatal care. 97% of the women were followed up, 9,394 who had followed the new programme, and 6,138 from clinics with the standard one. Women allocated to the new programme made, as planned, fewer visits than those in the standard programme (median 4 vs 6 visits, respectively). The proportion of antenatal referrals was also lower (13.6 vs 15.3%; odds ratio 0.87 [95% CI 0.79-0.95]) because of significantly fewer referrals for pregnancy-induced hypertension (2.5 vs 3.8%; 0.66 [0.55-0.79]). Nevertheless, there were significantly fewer labour referrals for severe hypertension or eclampsia (2.1 vs 2.6%; 0.81 [0.66-1.00]). The risk for preterm (< 37 weeks) delivery was significantly lower for women on the new programme (10.1 vs 11.5%; 0.86 [0.78-0.96]). There were no other significant differences between the programmes in other major indices of pregnancy outcome, including antenatal referrals for other causes, labour referrals, obstetric interventions, low birthweight, and perinatal and maternal mortality and morbidity. INTERPRETATION: An antenatal care programme with fewer more objectively oriented visits can be introduced without adverse effects on the main intermediate outcome pregnancy variables.

Bisphosphonates in the treatment of Charcot neuroarthropathy: a double-blind randomised controlled trial.

AIMS/HYPOTHESIS: The management of charcot neuroarthropathy, a severe disabling condition in diabetic patients with peripheral neuropathy, is currently inadequate with no specific pharmacological treatment available. We undertook a double-blind randomised controlled trial to study the effect of pamidronate, a bisphosphonate, in the management of acute diabetic Charcot neuroarthropathy. METHODS: Altogether 39 diabetic patients with active Charcot neuroarthropathy from four centres in England were randomised in a double-blind placebo-controlled trial. Patients received a single infusion of 90 mg of pamidronate or placebo (saline). Foot temperatures, symptoms and markers of bone turnover (bone specific alkaline phosphatase and deoxypyridinoline crosslinks) were measured over the 12 months, in 10 visits. All patients also had standard treatment of the Charcot foot. RESULTS: Mean age of the study group (59 % Type II (non-insulin-dependent) diabetes mellitus) was 56.3 +/- 10.2 years. The mean temperature difference between active and control groups was 3.6 +/- 1.7 degrees C and 3.3 +/- 1.4 degrees C, respectively. There was a fall in temperature of the affected foot in both groups after 2 weeks with a further reduction in temperature in the active group at 4 weeks (active and placebo vs baseline; p = 0.001; p = 0.01, respectively), but no difference was seen between groups. An improvement in symptoms was seen in the active group compared with the placebo group (p < 0.001). Reduction in bone turnover (means +/- SEM) was greater in the active than in the control group. Urinary deoxypyridinoline in the pamidronate treated group fell to 4.4 +/- 0.4 nmol/mmol creatinine at 4 weeks compared with 7.1 +/- 1.0 in the placebo group (p = 0.01) and bone-specific alkaline phosphatase fell to 14.1 +/- 1.2 u/l compared with 18.6 +/- 1.6 u/l after 4 weeks, respectively (p = 0.03). CONCLUSION/INTERPRETATION: The bisphosphonate, pamidronate, given as a single dose leads to a reduction in bone turnover, symptoms and disease activity in diabetic patients with active Charcot neuroarthropathy.

Randomised controlled trial of brief neonatal exposure to cows' milk on the development of atopy.

OBJECTIVE: To determine the effect of brief early exposure to cows' milk on atopy in the first 2 years of life. DESIGN: Double blind, placebo controlled, randomised feeding intervention trial (Bokaal study). SETTING: Dutch midwifery practices. PARTICIPANTS: 1533 breast fed neonates. INTERVENTION: Exposure to cows' milk protein (n = 758) or a protein free placebo (n = 775) during the first 3 days of life. MAIN OUTCOME MEASURES: Clinical atopic disease and any positive radioallergosorbent (RAST) tests at 1 year of age. RESULTS: Atopic disease in the first year was found in 10.0% (cows' milk) v 9.3% (placebo) of the children, with a relative risk of 1.07; in the second year, atopic disease was found in 9.6% v 10.2%, respectively, with a relative risk of 0.94. Per protocol analysis showed similar results. Any RAST positive test was found in 9.4% (cows' milk) v 7.9% (placebo) of children, with a relative risk of 1.19. Stratified analysis for high family risk of allergy showed a doubled incidence of atopic disease but no effect from the intervention. CONCLUSION: Early and brief exposure to cows' milk in breast fed children does not increase the risk of atopic disease in the first 2 years.

Can postal prompts from general practitioners improve the uptake of breast screening? A randomised controlled trial in one east London general practice.

OBJECTIVE: To determine the effect on the uptake of breast screening of a personalized letter from the general practitioner recommending mammography, sent to coincide with an invitation from the NHS breast screening programme. DESIGN: Randomised control trial with stratification of prognostic variables. SETTING: A group practice in Hackney, east London. SUBJECTS: 473 women invited for breast screening by the City and East London Breast Screening Service. OUTCOME MEASURE: Attendance for mammography. RESULTS: All women in the randomised trial were followed up; 134 of 236 (57%) randomly allocated to receive the prompting letter attended for mammography compared with 120 of 234 (51%) controls This difference was not significant (chi 2 = 1.43, p = 0.23) CONCLUSION: Personal recommendation by a letter prompting attendance for mammography from the general practitioner known best to women due to be screened did not improve uptake of breast screening in this east London practice. Other strategies are needed to increase uptake of mammography in inner cities.
