Impact of Medication Adherence on Emergency Department Visits in Patients with COPD in a Single Tertiary Hospital in Saudi Arabia.
Observational study in International journal of chronic obstructive pulmonary disease, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: There is a very limited information and studies on the impact of adherence to chronic obstructive pulmonary disease (COPD) medications in Saudi Arabia. We hypothesized that the adherence to COPD medication in our tertiary hospital is poor and can lead to frequent ED visits and longer hospitalization stays. The purpose of this study was to assess the impact of medication adherence in patients with COPD on emergency department (ED) visits and hospitalization. Methods: A single-center retrospective observational study included patients with a COPD exacerbation, who were admitted to a tertiary teaching hospital in Jeddah, Saudi Arabia from October 2017 to November 2020. The primary outcome was the rate of emergency department (ED) visit in one year. Secondary outcomes were hospitalization after ED visit and total hospital length of stay. Medication adherence was evaluated by using Fixed Medication Possession Ratio (FMPR). Patients with score of ≥0.80 were classified as high-adherent groups while patients with ratio <0.80 were on low-adherent groups. Results: A total of 266 patients enrolled in the study. Of those 266 patients, 139 patients were on high-adherent group and 127 were on low-adherent group. There was a significant difference between the high-adherent group and low-adherent group in the incidence of ED visit in one year 62 (44.6%) vs 73 (57.5%); P < 0.036, and hospitalization after the ED visit 26 (18.7%) vs 42 (33.1%); P = 0.007. However, there was no significant difference between the two groups in the total hospital length of stay. Conclusion: Among patients with COPD, there was a significant increase in ED visit per one year that leads to more hospitalization among patients with low adherence compared to patients with high adherence. This study highlights the importance of improving the medication adherence in patients with COPD.
