BACKGROUND: Inspired by the US Choosing Wisely(®), in 2016 the Swiss Society of
General Internal Medicine released a list of five treatments or diagnostic tests
used in the hospital and considered unnecessary based on not improving patient
care and adding to health care costs. These "Smarter Medicine" recommendations
were implemented in the Department of Internal Medicine, Uster Hospital, in
August 2016. They were supported by lectures and weekly email communications. We
analyzed the number of blood draws before and after implementation of the
recommendation aimed at reducing blood tests. METHODS: This retrospective
analysis was conducted in the Department of Internal Medicine, Uster Hospital,
Canton of Zurich, Switzerland. Patients hospitalized in the 3 months before and
after implementation were analyzed. RESULTS: A total of 2023 hospitalizations
were analyzed. There was a significant decrease in the number of blood draws
after introduction of the recommendation: before implementation, the median
number of blood draws per patient was 4 (interquartile range [IQR], 2-7); after
implementation, the median was 4 (IQR, 2-6; P = 0.002). Indeed, since 46% of the
patients in the first group had more than four blood tests, this ratio decreased
to 39% after implementation. DISCUSSION: Inappropriate blood draws may lead to
anemia, patient discomfort and false-positive results. The simple and low-cost
interventions used to implement "Smarter Medicine" have changed physician
behavior by reducing the number of blood orders. These results are promising.
Whether such recommendations will impact patient and clinical outcomes remains
unknown; hence, further studies are needed to clarify this issue.
