چکیده

مقـدمـه: پزشکی مبتنی برشواهد فرآیند دریافت، نقد و به‌ کارگیری نتایج تحقیقات بر بالین بیماران می‌باشد. با وجود انتشار مقالات متعدد پیرامون میزان تطابق عملکرد پزشکان با شواهد علمی در سایر کشورها، هنوز مطالعه‌ای در ایران صورت نگرفته است. هدف این مطالعه، تعیین این مطلب بود که چند درصد از خدمات بالینی ارایه شده در بخش‌های داخلی یک بیمارستان آموزشی منتخب، منطبق با شواهد معتبر علمی است.روش‌ها: پرونده‌ی 103 بیمار که در مدت یک ماه در هفت بخش داخلی بیمارستان آموزشی الزهرا (س) دانشگاه علوم پزشکی اصفهان بستری شده بودند، وارد مطالعه گردید. برای هر بیمار دو شاخص تشخیص و درمان اولیه مشخص شد. سپس منابع علمی پزشکی مبتنی بر شواهد جهت یافتن کارآزمایی‌های بالینی، مقالات مروری و راه‌کارهای طبابت بالینی جستجو شد و میزان تطابق درمان ارایه شده به بیمار با درمان منتخب بر مبنای بهترین یافته‌های پژوهشی مبتنی بر شواهد محاسبه و استخراج شد. یافته‌ها: بر اساس جستجوی انجام شده 71 مورد (9/68 درصد) از بیماران، مداخلات اولیه‌ی منطبق با سطح یک شواهد علمی و 32 مورد (1/31 درصد) منطبق با شواهد سطح دو علمی را دریافت کرده بودند. هیچ بیماری مداخله‌ی منطبق با شواهد سطح سه دریافت نکرده بود.نتیجه گیری: بیش از نیمی از مداخلات انجام شده در بخش‌های داخلی بیماستان آموزشی منتخب، منطبق بر شواهد معتبر علمی بوده است. تکرار این مطالعه برای سایر رشته‌ها و پزشکان غیر هیأت علمی ضروری است.

چکیده [English]

Introduction: Evidence based practice is an approach to clinical practice which emphasizes the use of best clinical researches as a component of clinical decision making. The aim of this study was to determine the percentage of current clinical decision making and disease management which is based and supported by high-level evidence in an educational hospital located in Isfahan, Iran.Methods: A cross-sectional study was carried on 103 patients who were admitted during one month to seven Internal medicine wards in Alzahra hospital. For each patient, the primary diagnosis and primary treatment were recorded. Evidence based resources were then searched for randomized controlled trials (RCT’s), systematic reviews and clinical practice guidelines to find the best research evidence that the treatments were effective. The main outcome measure was the level of evidence which supports the primary intervention for the primary diagnosis of each patient.Finding: Level I evidence (at least one randomized trial) supported the primary intervention used in 68.9% of internal admissions and level II evidence (convincing non-experimental evidence) supported the primary intervention in 31.1% of admissions. None of patients received intervention with level III supporting evidence.Conclusion: Most patients had received high level supported interventions. It seems that we should repeat this study in other wards. Also it may be recommended to design some educational evidence based practice for non academic physicians.
