Clinical prediction rules: what are they and what do they tell us?

QUESTION Clinical prediction rules are research-based tools that quantify the contributions of relevant patient characteristics to provide numeric indices that assist clinicians in making predictions. Clinical prediction rules have been used to describe the likelihood of the presence or absence of a condition, assist in determining patient prognosis, and help the classification of patients for ...

Development and application of clinical prediction rules to improve decision making in physical therapist practice.

C linical prediction rules (CPRs) are tools designed to improve decision making in clinical practice by assisting practitioners in making a particular diagnosis, establishing a prognosis, or matching patients to optimal interventions based on a parsimonious subset of predictor variables from the history and physical examination.1,2 Clinical prediction rules have been developed to improve decisi...

Validation, updating and impact of clinical prediction rules: a review.

OBJECTIVE To provide an overview of the research steps that need to follow the development of diagnostic or prognostic prediction rules. These steps include validity assessment, updating (if necessary), and impact assessment of clinical prediction rules. STUDY DESIGN AND SETTING Narrative review covering methodological and empirical prediction studies from primary and secondary care. RESULT...

Systematic review of clinical prediction rules for neuroimaging in the evaluation of dementia.

BACKGROUND Clinical practice guidelines for dementia do not recommend routine neuroimaging but vary in their recommended clinical prediction rules to identify patients who should undergo neuroimaging for potentially reversible causes of dementia. METHODS Using a MEDLINE search supplemented by other strategies, we identified studies from January 1, 1983, through December 31, 1998, that evaluat...

Should a head-injured child receive a head CT scan? A systematic review of clinical prediction rules.

CONTEXT Given radiation- and sedation-associated risks, there is uncertainty about which children with head trauma should receive cranial computed tomography (CT) scanning. A high-quality and high-performing clinical prediction rule may reduce this uncertainty. OBJECTIVE To systematically review the quality and performance of published clinical prediction rules for intracranial injury in chil...
