A clinical prediction rule is type of medical research study in which researchers try to identify the best combination of medical signs, symptoms, and other findings in predicting the probability of a specific disease or outcome.[1] Prediction rules may offer a more practical alternative to Bayesian reasoning.[2]
Physicians have difficulty in estimated risks of diseases; frequently erring towards overestimation[3], perhaps due to cognitive biases such as base rate fallacy in which the risk of an adverse outcome is exaggerated.
Methods
In a prediction rule study, investigators identify a consecutive group of patients who are suspected of a having a specific disease or outcome. The investigators then compare the value of clinical findings available to the physician versus the results of more intensive testing or the results of delayed clinical follow up.
A survey of methods concluded "the majority of prediction studies in high impact journals do not follow current methodological recommendations, limiting their reliability and applicability."[4]
Effect on health outcomes
Using clinical prediction rules for "Teaching physicians to make better judgments of disease probability may not alter their treatment decisions." [5]
Changing decisions of health care providers
Few prediction rules have had the consequences of their usage by physicians quantified.[6]
When studied, the impact of providing the information alone (for example, providing the calculated probability of disease) has been negative.[7][5]
However, when the prediction rule is implemented as part of a critical pathway, so that a hospital or clinic has procedures and policies established for how to manage patients identified as high or low risk of disease, the prediction rule has more impact on clinical outcomes.[8]
The more intensively the prediction rule is implemented the more benefit will occur.[9]
Changing decisions of patients
A randomized controlled trial of patients at very high risk of coronary events found that use of two equations (http://www.chiprehab.com/CVD/) for predicting coronary events along with tailored feedback, may improve cholesterol values.[10]
Adverse effects
Patients may not be comfortable with the way a doctor may integrate decision support into practice.[11]
