Randomized Controlled Trial Multicenter Study Clinical Trial
Cost effectiveness of ward based non-invasive ventilation for acute exacerbations of chronic obstructive pulmonary disease: economic analysis of randomised controlled trial.
To evaluate the cost effectiveness of standard treatment with and without the addition of ward based non-invasive ventilation in patients admitted to hospital with an acute exacerbation of chronic obstructive pulmonary disease. ⋯ Non-invasive ventilation is a highly cost effective treatment that both reduced total costs and improved mortality in hospital.

Multicenter Study
Impact of NHS walk-in centres on the workload of other local healthcare providers: time series analysis.
To assess the impact of NHS walk-in centres on the workload of local accident and emergency departments, general practices, and out of hours services. ⋯ It will be necessary to assess the impact of walk-in centres in a larger number of sites and over a prolonged period, to determine whether they reduce the demand on other local NHS providers.

Multicenter Study
Effect of NHS walk-in centre on local primary healthcare services: before and after observational study.
To assess the effect of an NHS walk-in centre on local primary and emergency healthcare services. ⋯ The NHS walk-in centre did not greatly affect the workload of local general practitioners. However, the workload of the local minor injuries unit increased significantly, probably because it was in the same building as the walk-in centre.

Multicenter Study
Prospective cohort study of routine use of risk assessment scales for prediction of pressure ulcers.
To evaluate whether risk assessment scales can be used to identify patients who are likely to get pressure ulcers. ⋯ Although risk assessment scales predict the occurrence of pressure ulcers to some extent, routine use of these scales leads to inefficient use of preventive measures. An accurate risk assessment scale based on prospectively gathered data should be developed.

Multicenter Study Comparative Study
Natural experiment examining impact of aggressive screening and treatment on prostate cancer mortality in two fixed cohorts from Seattle area and Connecticut.
To determine whether the more intensive screening and treatment for prostate cancer in the Seattle-Puget Sound area in 1987-90 led to lower mortality from prostate cancer than in Connecticut. ⋯ More intensive screening for prostate cancer and treatment with radical prostatectomy and external beam radiotherapy among Medicare beneficiaries in the Seattle area than in the Connecticut area was not associated with lower prostate cancer specific mortality over 11 years of follow up.
