OBJECTIVE: To explore the impact of increasing interest and investment in
patient-centered research, this study sought to describe patterns of comparative
effectiveness research (CER) and patient-reported outcomes (PROs) in
pharmacologic intervention studies published in widely read medical journals from
2004-2013. DESIGN AND SETTING: We identified 2335 articles published in five
widely read medical journals from 2004-2013 with ?1 intervention meeting the US
Food and Drug Administration's definitions for a drug, biologic, or vaccine. Six
trained reviewers extracted characteristics from a 20% random sample of articles
(468 studies). We calculated the proportion of studies with CER and PROs. Trends
were summarized using locally-weighted means and 95% confidence intervals.
RESULTS: Of the 468 sampled studies, 30% used CER designs and 33% assessed PROs.
The proportion of studies using CER designs did not meaningfully increase over
the study period. However, we observed an increase in the use of PROs.
CONCLUSIONS: Among pharmacological intervention studies published in widely read
medical journals from 2004-2013, we identified no increase in CER. Randomized,
placebo-controlled trials continue to be the dominant study design for assessing
pharmacologic interventions. Increasing trends in PRO use may indicate greater
acceptance of these outcomes as evidence for clinical benefit.
