Beschreibungen/Notizen
Decisions in medicine are made on the basis of knowledge and reasoning, often in shared conversations with patients and families in consideration of clinical practice guideline recommendations, individual preferences, and individual goals. Observational studies can provide valuable knowledge to inform guidelines, decisions, and policy.
The American Thoracic Society (ATS) created a multidisciplinary
committee to develop a research statement to clarify the role of observational studies-alongside randomized controlled trials (RCTs)-in informing clinical decisions in pulmonary, critical care, and sleep medicine.
The committee examined the strengths of observational studies assessing causal effects, how they complement RCTs, factors that impact observational study quality, perceptions of observational research, and, finally, the practicalities of incorporating observational research into ATS clinical practice guidelines.
There are strengths and weakness of observational studies as well as RCTs. Observational studies can provide evidence in representative and diverse patient populations. Quality observational studies should be sought in the development of ATS clinical practice guidelines, and medical decision-making in general, when
) no RCTs are identified or RCTs are appraised as being of low- or very low-quality (
);
) RCTs are of moderate quality because of indirectness, imprecision, or inconsistency, and observational studies mitigate the reason that RCT evidence was downgraded (
); or
) RCTs do not provide evidence for outcomes that a guideline committee considers essential for decision-making (e.g., rare or long-term outcomes; "
).
Observational studies should be considered in developing clinical practice guidelines and in making clinical decisions.
