Randomised controlled trial of Helicobacter pylori testing and endoscopy for dyspepsia in primary care.

OBJECTIVE: To determine the cost effectiveness of a strategy of near patient Helicobacter pylori testing and endoscopy for managing dyspepsia. DESIGN: Randomised controlled trial. SETTING: 31 UK primary care centres. PARTICIPANTS: 478 patients under 50 years old presenting with dyspepsia of longer than four weeks duration. INTERVENTIONS: Near patient testing for H pylori and open access endoscopy for patients with positive results. Control patients received acid suppressing drugs or specialist referral at general practitioner's discretion. MAIN OUTCOME MEASURES: Cost effectiveness based on improvement in symptoms and use of resources at 12 months; quality of life. RESULTS: 40% of the study group tested positive for H pylori. 45% of study patients had endoscopy compared with 25% of controls. More peptic ulcers were diagnosed in the study group (7.4% v 2.1%, P=0.011). Paired comparison of symptom scores and quality of life showed that all patients improved over time with no difference between study and control groups. No significant differences were observed in rates of prescribing, consultation, or referral. Costs were higher in the study group ( 367.85 pound sterling v 253.16 pound sterling per patient). CONCLUSIONS: The test and endoscopy strategy increases endoscopy rates over usual practice in primary care. The additional cost is not offset by benefits in symptom relief or quality of life.

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.

Improving attendance for breast screening among recent non-attenders: a randomised controlled trial of two interventions in primary care.

OBJECTIVES: To examine the effectiveness and cost-effectiveness of two primary care based interventions aimed at increasing breast screening uptake for women who had recently failed to attend. SETTING: 13 General practices with low uptake in the second round of breast screening (below 60%) in north west London and the West Midlands, United Kingdom. Participants were women in these practices who were recent non-attenders for breast screening in the third round. METHODS: Pragmatic factorial randomised controlled trial, with people 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 randomisation and cost-effectiveness of the interventions. RESULTS: 1,158 Women were individually randomised as follows: 289 control; 291 letter; 290 flag; 288 both interventions. Attendance was ascertained for 1,148 (99%) of the 1,158 women. Logistic regression adjusting for the other intervention and practice produced an odds ratio (OR) for attendance of 1.51 (95% confidence interval (95% CI 1.02 to 2.26; p=0.04) for the letter, and 1.39 (95% CI 0.93 to 2.07; p=0.10) for the flag. Health service costs/ additional attendance were 35 pounds (letter) and 65 pounds (flag). CONCLUSIONS: Among recent non-attenders, the letter was effective in increasing breast screening attendance. The flag was of equivocal effectiveness and was considerably less cost-effective than the letter.

Cost effectiveness of initial endoscopy for dyspepsia in patients over age 50 years: a randomised controlled trial in primary care.

BACKGROUND: Dyspepsia can be managed by initial endoscopy and treatment based on endoscopic findings, or by empirical prescribing. We aimed to determine the cost effectiveness of initial endoscopy compared with usual management in patients with dyspepsia over age 50 years presenting to their primary care physician. METHODS: 422 patients were recruited and randomly assigned to initial endoscopy or usual management. Primary outcomes were effect of treatment on dyspepsia symptoms and cost effectiveness. Secondary outcomes were quality of life and patient satisfaction. Total costs were calculated from individual patient's use of resources with unit costs applied from national data. Statistical analysis of uncertainty on incremental cost-effectiveness ratio (ICER) was done along with a sensitivity analysis on unit costs with cost-effectiveness acceptability curves. FINDINGS: In the 12 months following recruitment, 213 (84%) patients had an endoscopy compared with 75 (41%) controls. Initial endoscopy resulted in a significant improvement in symptom score (p=0.03), and quality of life pain dimension (p=0.03), and a 48% reduction in the use of proton pump inhibitors (p=0.005). The ICER was Pound Sterling1728 (UK Pound Sterling) per patient symptom-free at 12 months. The ICER was very sensitive to the cost of endoscopy, and could be reduced to Pound Sterling165 if the unit cost of this procedure fell from Pound Sterling246 to Pound Sterling100. INTERPRETATION: Initial endoscopy in dyspeptic patients over age 50 might be a cost-effective intervention.

A review of parotid pleomorphic adenomas in the West Midlands region 1977-1986.

The aim of this study was to review the management of parotid pleomorphic adenomas in the West Midlands Regional Health Authority. The study population consisted of all cases of pleomorphic adenomas arising in the parotid and registered with the West Midlands Regional Cancer Registry between 1 January 1977 and 31 December 1986. Variables included in the analysis were: age, sex, year of diagnosis, treatment centre, consultant specialty, operative procedure, completeness of tumour resection and treatment modality. The main findings were that the choice of operative procedure and the use of adjuvant radiotherapy varied significantly between treatment centres and could not be explained by intraregional variation in the distribution of patient and disease related factors; less than one-third of patients in this series were managed according to accepted treatment protocols.

Incidence and survival of malignant parotid tumours in the West Midlands region 1977-1986.

The aim of this study was to describe the incidence and survival of patients with malignant parotid tumours resident in the West Midlands Regional Health Authority. The study population consisted of all patients with malignant tumours arising in the parotid gland and registered with the West Midlands Regional Cancer Registry between 1 January 1977 and 31 December 1986. Variables included in the analysis were: age, sex, date of diagnosis, side of origin, tumour histology, vital status and date of death. No temporal change in the incidence of parotid tumours was observed. More tumours originated within the left parotid gland (chi 2(1) = 4.0, P < 0.05). The 5-year actuarial survival for all tumours was 55.7%. When a Cox's proportional hazards regression model was fitted to the data, age at diagnosis (60-74 years) and histological type were found to be the critical determinants of outcome.
