From evidence to practice: real-world insights into outpatient management of acute uncomplicated diverticulitis.
Observational study in Techniques in coloproctology, 2024. 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
backgroundDiverticulitis is experiencing a significant increase in prevalence and its widespread in-hospital management results in a high burden on healthcare systems worldwide. This study compared inpatient and outpatient approach of acute non-complicated diverticulitis using a non-selected population in a real-world setting.
methodsThis observational retrospective study included all consecutive patients from two Portuguese institutions diagnosed between January 2017 and December 2021 with non-complicated diverticulitis according to the modified Hinchey Classification. The primary endpoints were to identify criteria for inpatient treatment and compare the outcomes on the basis of the treatment regimen. The secondary endpoints were to determine the predictive factors for clinical outcomes, focusing on treatment failure, pain recurrence, and the need for elective surgery following the initial episode.
resultsA total of 688 patients were included in this study, 437 treated as outpatients and 251 hospitalized. Inpatient management was significantly associated with higher preadmission American society of anesthesiologists (ASA) score (p = 0.004), fever (p = 0.030), leukocytosis (p < 0.001), and elevated C-reactive protein (CRP) (p < 0.001). No significant association was found between failure of conservative treatment and patient's age, ASA score, baseline CRP, presence of systemic inflammatory response syndrome (SIRS), and inpatient or outpatient treatment regimen. Pain recurrence was significantly associated with higher CRP levels (p = 0.049), inpatient treatment regime (p = 0.009) and post index episode mesalazine prescription (p = 0.006). Moreover, the need for elective surgery was significantly associated with the presence of previous episodes (p = 0.004) and pain recurrence (p < 0.001).
conclusionsThe majority of patients with uncomplicated diverticulitis of the left colon experience successful conservative approach and can be safely managed in an ambulatory setting. Neither treatment failure, recurrence of pain, or need for posterior elective surgery are associated with outpatient treatment regimen.
