Reducing inappropriate transthoracic echocardiography orders in normotensive patients with acute pulmonary embolism in a community hospital: a quality improvement project.
Article in BMJ open quality, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Transthoracic echocardiograms (TTEs) have limited value in guiding management of normotensive patients with acute pulmonary embolism (PE). Nevertheless, TTEs are frequently ordered inappropriately. This quality improvement project aimed to decrease inappropriate TTE orders by 30% over 6 months in patients with PE admitted to general internal medicine at a community hospital. Two interventions were implemented using successive plan-do-study-act (PDSA) cycles: educational sessions for physicians and the distribution of TTE-ordering algorithms for triaging of TTE appropriateness. Four audits on TTE orders for inpatients with PE were conducted throughout the project: a pre-intervention audit (pre-audit; March to August 2020), a post-intervention 1 audit (post-I1; August to September 2022), a post-intervention 2 audit (post-I2; December 2022 to February 2023) and a post-intervention audit (post-audit; March to August 2023). The primary outcome measure was the proportion of inappropriate to appropriate TTE orders during the pre-intervention and post-intervention periods. During the pre-audit, post-I1, post-I2 and post-audit periods, 89, 23, 20 and 158 patients, respectively, were admitted with PEs. 37, 10, 3 and 14 patients in each of these periods, respectively, received a TTE for PE-related reasons and were therefore included in the audits. 42%, 43%, 15% and 24% of patients, respectively, received a TTE for PE-related reasons. 89%, 50%, 67% and 79% of those TTEs, respectively, were inappropriate. There was a transient decrease in inappropriate to appropriate TTE orders ratio after the first intervention (p<0.005). Inappropriate investigations lead to additional healthcare costs and delays in patient care. This quality improvement project highlights an ongoing need to increase awareness surrounding TTE indications to improve appropriate utilisation. Next steps include further PDSA cycles with additional interventions to continue to try and decrease inappropriate TTE orders in the community hospital setting.
