Frequency of emergency medical service contacts after hospital admissions.
Article in Internal and emergency medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Identifying frequent users of Emergency Medical Services (EMS) in the post-discharge period can potentially direct interventions to prevent deterioration at home. This study aimed to describe the frequency of post-discharge emergency phone calls within 30 days after common medical and surgical categories of hospital admission. A retrospective cohort study retrieved data from the electronic medical record and the EMS Capital Region Denmark database after approval by the Danish Health Data Authority. The study investigated the number of 30-day EMS calls per 1000 days alive outside hospital in patients hospitalized due to acute exacerbation of chronic obstructive pulmonary disease (AECOPD), colorectal surgery, and 18 other disease categories. We included 16,338 patients with a discharge from hospital between August 2021 and August 2022.The overall number of EMS calls was 4,263 with 9.1 (95% confidence interval (95% CI)): 8.8-9.4) calls per 1000 patient days within 30 days. Patients discharged after medical hospitalization due to AECOPD contacted EMS 15 (95% CI: 13-16) times per 1000 patient days only surpassed by sepsis with 19 calls per 1000 patient days (95% CI: 17-21). Patients undergoing colorectal surgery had an EMS call frequency of 7.5 (95% CI: 6.4-8.7) and highest among types of surgery was hip- and knee replacements with 12 (95% CI: 11-13) calls per 1000 patient days. Patients discharged after hospitalization due to AECOPD and sepsis had a higher 30-day EMS call frequency compared with other medical cohorts, whereas major orthopedic surgery was followed by more EMS calls than admissions for colorectal surgery.
