Abstract

Sağlık araştırmalarında yan tutma önemli olup, bunu tarafsız bir şekilde ölçmek kolay değildir. Bu araştırmanın amacı; gözlemsel araştırmalar için kullanımı kolay olan, kapsamlı, maliyet ve zaman etkin bir yan tutma kontrol aracı geliştirilmekti. Bu araştırma, Haziran 2018 – Haziran 2020 tarihleri arasında yürütülen metodolojik bir çalışmaydı. Araştırmanın ana basamakları; yan tutma sorgulanacak maddeler için literatür taramak, uzman görüşleri, Delphi panelleri, bias risk değerlendirme aracının ana hatlarının oluşturulmak ve içerik geliştirilmek, araştırmanın istatistiksel analizini yapmak ve sonucunu raporlamaktı. Literatür taraması, araştırmacılar tarafından önceden belirlenmiş anahtar kelimeler ile yapıldı. Uzman görüşlerini alabilmek için “Uzman Değerlendirme Formu” geliştirilip kullanıldı. Kapsam geçerliliğini değerlendirmek için Kapsam Geçerlilik Oranı (KGO) kullanılmış olsa da esas olarak uzman görüşüne dayalı olarak yapıldı. Üç Delphi paneli gerçekleştirildi. Geliştirilen aracın adının Bias Risk Değerlendirme Aracı (BiRDA) olmasına karar verildi. Kesitsel araştırmalar için BiRDA-Ke, vaka kontrol araştırmaları için BİRDA-VK, kohort araştırmaları için BiRDA-Ko olarak kullanılması kabul edildi. 67 uzmana toplam 71 adet uzman değerlendirme formu gönderildi ve bu formların 44’üne geri dönüş yapıldı. Delphi panellerinin sonucunda; 67 maddelik BiRDA-Ke, 69 maddelik BiRDA-VK ve 70 maddelik Ko araçları geliştirildi. BiRDA araçları, eğitimde, araştırmaya hazırlık aşamasında veya yayın süreçlerinde kullanılabilir. Fakat, bu tür araçların kullanımı genellikle pratik olmadığı için mobil / internet uygulaması olarak kullanımı veya ileri çalışmalarda yapay zekâ teknolojileri ile kullanımı kolaylaştıracaktır.

A COMPLEMENTARY BIAS RISK ASSESSMENT TOOL (BIRAT CHECKLIST) FOR OBSERVATIONAL STUDIES: A METHODOLOGICAL STUDY

Abstract

Assessment of bias in health studies is important and not easy to measure objectively. The aim of this study was to develop an easy-to-use, comprehensive, cost effective and time efficient bias control tool for observational studies. This was a methodological study conducted between June 2018 – June 2020. Literature review to extract items, expert opinions, Delphi panels, construction of the framework and the content of the tool, statistical analysis and reporting of the study were the main steps. Literature review was conducted with prespecified keywords by researchers. “Expert Assessment Form” was used to evaluate expert opinions. Although Content Validity Ratio (CVR) was used to check the content validity, it was mainly based on consensus of experts. Three Delphi panels were carried out. The name of the developed tool was decided to be Bias Risk Assessment Tool (BiRAT). It was considered to use the abbreviations BiRAT-CS for cross-sectional studies, BiRAT-CC for case-control studies and BiRAT-Co for cohort studies. Descriptive statistics A total of 71 expert assessment forms were sent to 67 experts and 44 of them were received. As a result of the assessments made after the Delphi panels; 67-item BiRAT-CS, 69-item BiRAT-CC and 70-item BiRAT-Co were developed. BiRAT tools may be used in training, preparing for a study, or publication process. However, bias assessment tools should be used with mobile / online applications or artificial intelligence technologies for easier use and further development since the use of them were generally impractical.
