Profiles of inpatient psychiatry referrals: a 4-year analysis in a Consultation-Liaison Psychiatry service.
Observational study in BMC psychiatry, 2026. 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
backgroundConsultation-Liaison Psychiatry (CLP) services are essential for addressing the psychiatric needs of patients with complex medical conditions in general hospitals.
aimsThe study aims to characterize profiles of inpatient psychiatry referrals and describe referral patterns and evaluate temporal trends between referrals, patient demographics, and psychiatric and somatic diagnoses.
methodData from January 2020 to December 2023 were collected from a CLP service during and after the pandemic, using psychiatric diagnoses from the International Classification of Diseases, Tenth Revision (ICD-10). Statistical analyses, including interrupted time series analysis with four periods, and including linear and segmented analyses, plus selective use of autocorrelation tests, were conducted to examine referral patterns and their associations with socio-demographic factors.
results6,105 patients were referred to the CLP Service during the study period, which was 6.73% of all hospital admissions. Internal medicine and Pneumology exhibited consistently high referrals, while services like Rheumatology and Endocrinology had lower rates. Common somatic diagnoses included neoplasms (20.7%) and respiratory diseases (9.4%), while neurotic, stress-related, and somatoform disorders were prevalent psychiatric diagnoses (42.5%). Interrupted time series analysis revealed fluctuations in monthly care visits, with notable decreases coinciding with the onset of the COVID-19 pandemic.
conclusionsOur study elucidated the characteristics of patients receiving CLP services at a major Peruvian general hospital, revealing depression as a prevalent reason for consultation, and highlighting the dynamic nature of psychiatric care delivery, especially amidst the COVID-19 pandemic.
