OBJECTIVES:   The comparative effect of chiropractic vs medical care on health, as used in everyday practice settings by older adults, is not well understood. The purpose of this study is to examine how chiropractic compares to medical treatment in episodes of care for uncomplicated back conditions. Episodes of care patterns between treatment groups are described, and effects on health outcomes among an older group of Medicare beneficiaries over a 2-year period are estimated.

METHODS:   Survey data from the nationally representative Survey on Assets and Health Dynamics among the Oldest Old were linked to participants’ Medicare Part B claims under a restricted Data Use Agreement with the Centers for Medicare and Medicaid Services. Logistic regression was used to model the effect of chiropractic use in an episode of care relative to medical treatment on declines in function and well-being among a clinically homogenous older adult population. Two analytic approaches were used, the first assumed no selection bias and the second using propensity score analyses to adjust for selection effects in the outcome models.

RESULTS:   Episodes of care between treatment groups varied in duration and provider visit pattern. Among the unadjusted models, there was no significant difference between chiropractic and medical episodes of care. The propensity score results indicate a significant protective effect of chiropractic against declines in activities of daily living (ADLs), instrumental ADLs, and self-rated health (adjusted odds ratio [AOR], 0.49; AOR, 0.62; and AOR, 0.59, respectively). There was no difference between treatment types on declines in lower body function or depressive symptoms.

Tamiflu: Millions wasted on flu drug, claims major report

The UK has spent £473m on Tamiflu, which is stockpiled by governments globally to prepare for flu pandemics.

The Cochrane Collaboration claimed the drug did not prevent the spread of flu or reduce dangerous complications, and only slightly helped symptoms.

The manufacturers Roche and other experts say the analysis is flawed.

The antiviral drug Tamiflu was stockpiled from 2006 in the UK when some agencies were predicting that a pandemic of bird flu could kill up to 750,000 people in Britain. Similar decisions were made in other countries.

Hidden data

The drug was widely prescribed during the swine flu outbreak in 2009.

Drug companies do not publish all their research data. This report is the result of a colossal fight for the previously hidden data into the effectiveness and side-effects of Tamiflu.

It concluded that the drug reduced the persistence of flu symptoms from seven days to 6.3 days in adults and to 5.8 days in children. But the report’s authors said drugs such as paracetamol could have a similar impact.

On claims that the drug prevented complications such as pneumonia developing, Cochrane suggested the trials were so poor there was “no visible effect”.
