Clinical randomized trials are experimental situations where some patients might received excellent care. What happens after the end of the trial? This a key ethical question should be answered in all proyects and programs of clinical trial.

Medicalization of aging and the testosterone deficiency syndrome

16 Dec

Over the last few years it has been proposed that the simple fact of having testosterone below the normal levels, which occurs with the passage of time, provokes a constellation of disorders. Testosterone therapy in the management of TDS (testosterone deficiency syndrome) is not justified, because there is no clear benefit in the relevant primary endpoints and there are alarming results on the possible risks.
Increasing consumption responds to the success of awareness raising campaigns. TDS is a clear example of disease mongering.

Crying patients in general/family practice: incidence, reasons for encounter and health problems

16 Dec

Despite evidence demonstrating the benefits of understanding patients, there is a paucity of information about how physicians address psychological and social concerns of patients. Patients cried in 157 encounters out of a total of 18,627 giving an incidence rate of 8.4 per thousand. More frequent reasons for encounters were: feeling depressed (12.7%), social handicap (mainly social isolation/living alone) (6.4%), relationship problem with partner (5.1%) and feeling anxious (3.2%). More frequent health problems were: depressive disorder (23.6%), anxiety disorder (8.3%), cerebrovascular disease (5.1%) and loss/death of partner (3.8%).

A few reasons to say no, thanks, to influenza vaccines

13 Sep

Influenza is a very common infection that spreads during winter time. In general flu is a lightly disease, but it may complicate the evolution of chronic patients, and even healthy ones. The best answer to stop the propagation is just to wash your hands. But official institutions and private organizations push to introduce influenza vaccine in children, elderly and health professionals, even asking for mandatory vaccination. There are no scientific bases for this proposal. See the text with links to the best evidence about this question, many from Cochrane Reviews.

Primary health care oriented systems, for whom, why and how

4 Jun

Health systems are social products, and as such they cannot being invented. They are expression of the final election between “freedom” and “equity”. Freedom means that each person may select and pay for the needed health services. Equity means solidarity, to help those in need even at the cost that are fit. Only the USA lacks an universal public health system; but countries as Germany, Japan and Switzerland, and others also favours “freedom”. “Equity” is important in countries like Denmark, Spain and the UK, and others, where primary health care is important.

Quaternary prevention: a summary

4 Jun

Quaternary prevention is the prevention of harms by medical interventions and as such a foundation block of medicine (primum non nocere). All services have adverse effects, all services might produce damage to health. A few services produce more benefits than harms in specific situations. Unnecessary and inappropriate services mainly produce harms, and few benefits if any.

Clinical care and health disparities

10 Apr

In this review, we consider empirical studies from the United States and elsewhere, and we focus on how one aspect of health systems, clinical care, contributes to maintaining systematic differences in health across population groups characterized by social disadvantage. We consider inequities in clinical care and the policies that influence them. We develop a framework for considering the structural and behavioral components of clinical care and review the existing literature for evidence that is likely to be generalizable across health systems over time.
