Summary
Implementing "Smarter Medicine" recommendations significantly reduced unnecessary blood draws in hospitalized patients. This initiative lowered blood test frequency, showing promise in optimizing medical practices and potentially improving patient care.
Area of Science:
- Internal Medicine
- Healthcare Management
- Patient Safety
Background:
- Swiss Society of General Internal Medicine developed
- Smarter Medicine
- recommendations in 2016, inspired by US Choosing Wisely®.
- These guidelines identified unnecessary tests and treatments contributing to healthcare costs.
- Recommendations were implemented in Uster Hospital's Internal Medicine Department in August 2016.
Purpose of the Study:
- To evaluate the impact of
- Smarter Medicine
- recommendations on blood draw frequency.
- To assess changes in physician ordering behavior regarding blood tests.
Main Methods:
- Retrospective analysis of hospitalizations at Uster Hospital.
- Comparison of blood draw data from 3 months before and after recommendation implementation.
- Analysis included 2023 hospitalizations.
Main Results:
- A significant decrease in the median number of blood draws per patient was observed post-implementation (4 [IQR, 2-6]) compared to pre-implementation (4 [IQR, 2-7]; P = 0.002).
- The proportion of patients with more than four blood tests decreased from 46% to 39%.
- Interventions included lectures and weekly email communications.
Conclusions:
- The
- Smarter Medicine
- initiative successfully altered physician behavior, reducing unnecessary blood orders.
- Low-cost interventions proved effective in changing practice.
- Further research is needed to determine the impact on patient and clinical outcomes.

The human ear cannot distinguish between two sources of sound if they happen to reach within a specific time interval, typically 0.1 seconds apart. More than this, and they are perceived as separate sources.
Imagine the sound is reflected back to the ears. Assuming that the source is very close to the human, the difference between hearing the two sounds—the emitted sound and the reflected sound—may be more than the minimum time for perceiving distinct sounds. If this is the case,...

Choosing Between z and t Distribution
3.7K
The z and the Student t distribution estimate the population mean using the sample mean and standard deviation. However, to decide which distribution to use for a calculation, one needs to determine the sample size, the nature of the distribution, and whether the population standard deviation is known. If the population standard deviation is known and the population is normally distributed, or if the sample size is greater than 30, the z distribution is preferred. The Student t distribution is...

Empathy
10.1K
Some researchers suggest that altruism operates on empathy. Empathy is the capacity to understand another person’s perspective, to feel what he or she feels. An empathetic person makes an emotional connection with others and feels compelled to help (Batson, 1991). Empathy can be expressed in several ways, including cognitive, affective, and motor.

Attribution Theory
13.8K
Behavior is a product of both the situation (e.g., cultural influences, social roles, and the presence of bystanders) and of the person (e.g., personality characteristics). Subfields of psychology tend to focus on one influence or behavior over others. Situationism is the view that our behavior and actions are determined by our immediate environment and surroundings. In contrast, dispositionism holds that our behavior is determined by internal factors (Heider, 1958).

Correlations
36.5K
Correlation means that there is a relationship between two or more variables (such as ice cream consumption and crime), but this relationship does not necessarily imply cause and effect. When two variables are correlated, it simply means that as one variable changes, so does the other. We can measure correlation by calculating a statistic known as a correlation coefficient. A correlation coefficient is a number from -1 to +1 that indicates the strength and direction of the relationship between...

Group Design
10.7K
The most basic experimental design involves two groups: the experimental group and the control group. The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between...
