BACKGROUND
Quality assessment in health care is a process of planned activities whose ultimate goal is to achieve a continuous improvement of medical care through the evaluation of structure, process, and outcome measures. Physicians and health care specialists involved with quality issues are faced with an enormous and nearly always increasing amount of literature to read and integrate
OBJECTIVE
To test the hypothesis that the number of publications in the field of health care quality increases over time, and particularly the number of high-evidence journal articles such as randomized control trials, systematic reviews, and ultimately, practice guidelines.
METHODS
We used MEDLINE database to retrieve relevant articles published between during the 29 year-period between 1/1/1989 and 12/31/2018. The search was conducted in March 2021. Publications from 2019 and 2020 were excluded because of incomplete data. We used the keywords "quality care", "quality management", "quality indicators" and "quality improvement” and limited the search fields to title and abstract.
RESULTS
During the 29-year evaluation period there was a significant cubic increase in the number of publications both in total number of publications and in the variety of publication types studied The rate of increase varied for different types of publications, with the largest increase in reviews, and the smallest increase in case reports. There was a systematic stagnation or even decrease in the number of publications starting in 2015 regardless of publication type.
CONCLUSIONS
Over the past 29 years the field of quality in health care has seen a significant yearly increase of published original studies with a relative stagnation since 2015. We suggest that contributors to this dynamic field of research should focus on producing more evidence based publications and guidelines
