Practice parameters and guidelines shape and influence the method and manner in which medicine is practiced. With more than 121 scales and methods of assessing and rating evidence, a comparison of practice parameters can appear daunting. An evaluation of the evidence engenders a sense of the evolution of a specialty and a roadmap for the future.
To assess the level of evidence underlying recommendations in allergy-immunology (AI) practice parameters.
We analyzed the practice parameters that guide AI Parajumpers Gobi Eco (n = 15), otolaryngology (n = 8), pediatrics (n = 13), and internal medicine (n = 10) as they appeared on August 30, 2012. Strength of recommendation data was compared after making adjustments for differences in rating scales.
The strength of recommendation calculated from strong to weak Boutique Parajumpers Paris for the AI practice parameters using a standardized format yielded the following grades: A in 195 (13.9%), B in 342 (24.4%), C in 606 (43.2%), D in 231 (16.4%), and E in 29 (2.1%). Controlled trial–based evidence (A and B) demonstrated considerable variability among individual AI practice parameters (range, 1.3%–100%). Evidence from controlled trials was lower in the subspecialty fields (38.3% in AI and 38.2% in otolaryngology) compared with the primary care fields (55.6% in pediatrics and 86.1% in internal medicine).
Considerable variability exists in the strength of recommendations within the AI practice parameters. The guidelines created by the primary care fields rest on a larger base of evidence collected from controlled trials. These findings likely reflect Parajumper Cuir Femme the adopted approach of making recommendations for less well-studied conditions and practices in AI to assist practitioners and patients and at the same time highlight the myriad opportunities for future research.
