2 Pendahuluan Dalam pekerjaan sehari hari, dokter dihadapkan pada kebutuhan informasi tentang masalah medis yg relevan (evidence-based) sementara arus informasi berubah dengan cepat.

3 Tujuan Mencari bukti yang relevan dan bermanfaat untuk meningkatkan kualitas perawatan pasien

4 Apa itu EBM ? Adalah integrasi bukti penelitian terbaru (the best research evidence), keterampilan klinik dan masalah yang ada pada pasien. Research evidence ---- > clinically relevan research. Clinical expertise ---- > ability to use our clinical skills and past experience to rapidly identify. Patients values > preference, concerns and expectations each patients bring to serve the patients.

5 Definisi Proses penelitian dan penggunaan informasi yg disajikan dalam literatur untuk memperbaiki perawatan pasien. Prosesnya: Mengubah “kekurangan pengetahuan” (knowledge deficit) menjadi pertanyaan klinik yg spesifik, Dgn cara meng-evaluasi bahan kepustakaan yg berhubungan dengan pertanyaan klinis, untuk memperbaiki perawatan pasien

6 LEVEL OF EVIDENCE Category I:
Evidence from at least one properly randomized controlled trial. Category II-1: Evidence from well-designed controlled trials without randomization. Category II-2: Evidence from well-designed cohort or case-control analytic studies, preferably from more than one center or research group. Category II-3: Evidence from multiple times series with or without intervention or dramatic results in uncontrolled experiments such as the results of the introduction of penicillin treatment in the 1940s. Category III: Opinions of respected authorities, based on clinical experience, descriptive studies and case reports, or reports of expert committees. [Source: Harris, R.P. et al. (2001).

Class IIa: in favor of usefulness Class IIb: usefulness is less well established Class III:Condition for which there is evidence/general agreement that a procedure/therapy is not useful/effective and may be harmful.

10 Aspek –aspek pembelajaran EBM :
Mengidentifikasi kekurangan pengetahuan. Menentukan pertanyaan klinik yg spesifik. Menemukan artikel yg relevan dalam literatur medis.

11 Langkah-langkah melakukan EBM
Merumuskan masalah (membuat pertanyaan klinik) Mencari informasi yang diperlukan Melakukan critical appraisal terhadap informasi yang didapat Menerapkan informasi yang didapat ke pasien Mengevaluasi keefektifitasannya

12 Langkah 1 Mempertanyakan pro dan kontra Terapi Pemeriksaan diagnostik
Prognosis dan risiko Cost effectiveness

13 Langkah 2 Mencari melalui internet, jurnal, textbook

14 Langkah 3 Melakukan initial appraisal: pengarang, tahun terbit, edisi atau revisi, penerbit, judul jurnal Melakukan content analysis: intended audience, rasional, cakupan, cara penulisan, review Jika berasal dari website dianalisis: accuracy, authority, currency, objectivity, coverage

15 Langkah 4 Bagaimana menerapkan ke pasien
Apakah ada hal-hal yang harus disesuaikan

16 Langkah 5 Evaluasi efek yang terjadi pada pasien tertentu
Menerapkan lanjutan atau diganti yang lain

17 Elemen dalam penerapan
P= patient I = intervention C = comparison O = outcome
