A review of 8 randomized controlled trials and 18 observational studies with a total of 2767 participants was carried out to evaluate the association of pedometer use with physical activity and health outcomes, according to an article in JAMA.
The study found that pedometer users in RCTs significantly increased their physical activity by 2491 steps per day more than control participants while those in observational studies 2183 steps per day over baseline. The pedometer users significantly decreased their body mass index by 0.38, the intervention participants significantly decreased their systolic blood pressure by 3.8 mm Hg. However, whether these changes are durable over the long term is undetermined.
A pedometer counts steps a person takes and the distance he/she has walked and has become popular as an everyday exercise motivator - a perfect Christmas gift for someone who wants to increase physical activitity and improve health.

Electronic health records alone do not improve quality of care
A group of Stanford and Harvard researchers assessed the association between electronic health records (EHR) use and the quality of care in a national survey and were suprised to find that EHR use made no difference in 14 of the 17 ambulatory qulaity indicators. They expected better quality from physicians using EHRs.
In 2 quality areas : not prescribing tranquilizers for depression and not ordering routine urinalysis in general medical examinations - doctors using EHRs performed significantly better than those who did not. But in the area of prescribing statins for patients with high cholestrol, physicians using EHRs performed significantly worse than those who did not.
The researchers said sophisticated EHR systems can be a valuable tool for physicians in improving care in outpatient settings, but it is not sufficient to have an EHR system that provides patient data and decision support, physicians have to be willing to act on that input.
The study is published in the July 9 issue of the Archives of Internal Medicine. 2007;167:1400-1405 "Electronic health record use and the quality of ambulatory care in the United States" Read the abstract .
