3. Summaries

4. Studies

1. System

Sumber informasi yang berupa bukti klinis dan secara reguler mengalami pembaruan,

mirip textbook atau ringkasan.

Kadang berintegrasi dengan informasi kesehatan yang lain dan dapat memberikan

rekomendasi atau panduan dalam manajemen pasien.

Jumlahnya tidak banyak, tapi sangat mudah di akses.

1. System

Contoh :

PIER (http://pier.acponline.org/)

Merck Manual (http://www.merck.com/mrkshared)

2. Synopses

Jumlahnya ratusan, mudah diakses, mempunyai 2 fungsi:

a.sebagai media informasi bagi klinisi akan adanya suatu perkembangan klinis

(ringkasan penelitian) dan,

b.sebagai suatu database artikel jika ternyata telah ada suatu panduan lengkap

dan sistematis (systematic reviews).

2. Synopses

Bandolier (http://www.jr2.ox.ac.uk/bandolier/)

ACP Journal Club: (http://www.acjc.org/)

InfoPOEMs: (http://www.infopoems.com/)

3. Summaries atau Syntheses

Merupakan kumpulan penelitian yang dianalisis secara sistematis (Systematic

Review), jumlahnya <50.000.

The Cochran Collaboration (http://www.cochran.org/)

3. Summaries atau Syntheses

4. Studies

Kumpulan penelitian asli atau primer, jumlahnya jutaan sehingga membutuhkan

kemampuan melacak tersendiri.

MEDLINE database

MEDLINE

Merupakan database yang disusun oleh The National library of Medicine dengan jumlah referensi lebih dari 15 juta dan bertambah

10.000 -20.000 artikel setiap minggu.

Dapat diakses melalui PubMed dan lain2nya.
