In the current era of evidence-based practice, interest in and use of clinical guidelines has assumed rapid and increasing prominence. Clinical practice guidelines have been defined as “systematically developed statements to assist practitioner and patient decisions about inappropriate health care for specific clinical circumstances” [1], the purpose of which is to “make explicit recommendations with a definite intent to influence what clinicians do” [2]. Thus, the use of guidelines has been advocated to reduce variations in clinical practice, determine and set standards and indicators, conduct audit and evaluation, and improve quality and safety of care.
