A clinical decision rule, known as the Ottawa SAH Rule, has been developed to identify neurologically intact patients with headache in the emergency department who have subarachnoid hemorrhage. The rule uses five variables from a patient's history and examination to predict diagnosis, showing 100% sensitivity but only 15.3% specificity.

The guidelines aim to increase access to the latest evidence-based medicine for patients with cardiac arrhythmias and heart failure.
Consumers tend to prefer products organized by benefits rather than features, as it leads to lower prices and perceived similarity. This can result in consumers sacrificing quality for price, but also makes it harder to notice differences between products.
A new survey tool is being developed to help pet owners monitor their dogs' quality of life during chemotherapy for cancer. The tool, based on a pilot study with 29 dog owners and veterinarians, found that certain behavioral changes can indicate the animal's quality of life, providing a common ground for treatment decisions.

A national survey found that adults often did not make informed medical decisions due to insufficient shared decision-making. Healthcare providers need to improve patient engagement by balancing discussions on pros and cons and regularly seeking patient input.
A study of 6,636 patients with heart attacks found that two-thirds prefer an active role in decision-making. Physicians who provide patient-centered care should directly ask patients about their decision-making preferences. The study aims to develop systems that respect these preferences and give patients the opportunity they desire.
A hospital-based study found that patients who want to participate in their medical decisions end up spending more time in the hospital and raising costs of their hospital stay by an average of $865. The study suggests that encouraging patients to be more involved may not reduce costs, but rather increase length of stay and costs. Prov...
The Ghana National Drugs Programme followed international recommendations on pediatric medicines, but faced challenges due to limited data on African settings. The programme ultimately included four out of five medicines in the national essential medicines list.
A study found significant variation in ICU patients' decisions to forgo life-sustaining therapies among US hospitals, with factors like hospital culture and physician practices playing a major role. Patient characteristics such as age, race, and functional status also influence these decisions.

Researchers surveyed over 800 participants to identify variables that predict high-risk sexual behavior. The cultural factor proved most reliable in predicting high-risk sexual behavior, with gender stereotyping, sexual fantasy, and pornography usage playing significant roles.
A University of Michigan study found that despite strong recommendations to use decision aids, there is a lack of evidence on whether they work effectively. The researchers reviewed 73 decision aids for breast, cervical, colon, and prostate cancers but only half were evaluated for subsequent screening behavior.
Researchers found that markets significantly lower moral standards, with subjects willing to accept killing a mouse for money. In market conditions, people focus on competition and profits over moral concerns, leading to an erosion of moral values.

A new study from the University of Miami School of Business Administration finds that offering free gifts with emotional products can double purchase likelihood, while cognitive products may see a 50% decrease in sales. The research suggests that marketers should consider the type of product and gift when designing promotions.
A study published in Neuron found that rats achieved optimal performance in less than 300 milliseconds, indicating that taking more time doesn't necessarily lead to better decisions. The researchers suggest that, for certain types of decisions, relying on intuition may be the most effective approach.
Researchers discovered that individuals with large choice sets overestimate probabilities of rare events and take riskier gambles. Participants gathered more information with smaller choice sets, but repeated this pattern with larger sets.
A Parkinson's drug has been shown to reverse age-related impairments in decision making in some older people. The study found that treating older adults with a dopamine-boosting drug improved their ability to learn from rewards and make better decisions, comparable to those in their twenties.
The Johns Hopkins University Applied Physics Laboratory has developed a novel method called PRedicting Infectious Disease Scalable Model (PRISM) to accurately predict dengue fever outbreaks several weeks before they occur. PRISM extracts relationships between clinical, meteorological, climatic and socio-political data in various regions.

The study suggests that considering possibilities is essential for making better decisions and could lead to interventions to improve cognitive function.
A new somatic symptom disorder in DSM-5 risks mislabeling many people as mentally ill due to a lack of specificity and high false-positive rate. The condition will classify excessive responses to distressing symptoms, potentially leading to inappropriate medical decision-making.
Researchers found that preschoolers can use introspection to improve accuracy in decision-making. They were more likely to choose a 'don't know' option when uncertain. The study, published in Child Development, suggests that children as young as 3 are aware of their uncertainty and can use it to inform their decisions.
