ReviewTarget payments in primary care: effects on professional practice and health care outcomes.
The method by which physicians are paid may affect their professional practice. Although payment systems may be used to achieve policy objectives (e.g. improving quality of care, cost containment and recruitment to under-served areas), little is known about the effects of different payment systems in achieving these objectives. Target payments are a payment system which remunerate professionals only if they provide a minimum level of care. ⋯ The evidence from the studies identified in this review is not of sufficient quality or power to obtain a clear answer to the question as to whether target payment remuneration provides a method of improving primary health care. Additional efforts should be directed in evaluating changes in physicians' remuneration systems. Although it would not be difficult to design a randomised controlled trial to evaluate the impact of such payment systems, it would be difficult politically to conduct such trials.

TB of the pleura is associated with inflammation and fibrosis. Steroids could reduce the effects of the inflammation, but the immunosuppression could make patients vunerable. ⋯ There is insufficient evidence to know whether steroids are effective in tuberculous pleural effusion.

ReviewAntiplatelet therapy for preventing stroke in patients with nonrheumatic atrial fibrillation and a history of stroke or transient ischemic attacks.
People with nonrheumatic atrial fibrillation who have had a transient ischemic attack or minor ischemic stroke are at risk of recurrent stroke. ⋯ Aspirin may reduce the risk of vascular events in people with nonrheumatic atrial fibrillation, but the effect shown in the single trial was not statistically significant.

Typical antipsychotic drugs are widely used as the first line treatment for people with schizophrenia. However, the atypical class of antipsychotic drugs are making important inroads into this approach. Atypical is a widely used term used to describe some antipsychotics which have a low propensity to produce movement disorders and raise serum prolactin. There is some suggestion that the different adverse effect profiles of atypical antipsychotic group make them more acceptable to people with schizophrenia. Ziprasidone is one of the newer atypicals with a high serotonin receptor affinity. ⋯ Currently data are limited. Ziprasidone may be an effective antipsychotic with less extrapyramidal effects than haloperidol. It also, however, causes more nausea and vomiting than the typical drugs, and, at present, there is no data suggesting that it is different to other atypical compounds. Well planned, conducted and reported long term randomised trials are needed if ziprasidone is to be accepted into everyday use.

ReviewPharmacotherapy for hypertension in women of different races.
To assess whether the relative and absolute benefit of hypertension treatment in women varies with age or race. ⋯ Hypertension treatment lowers the relative and absolute risk of cardiovascular morbidity and mortality in women ages 55 years and older, and in African American women of all ages. A greater effort should be made to increase awareness and treatment in these groups of women. Although relative risk reductions for cerebrovascular and cardiovascular events are similar for younger and older women, the NNT of younger women is at least 4 times higher. Decisions for treatment of hypertension in younger white women should be influenced by the individual patient's absolute risk of cardiovascular disease.
