Loneliness as a determinant of healthcare utilisation in older adults: a cross-sectional study in a Portuguese rural region.

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
backgroundLoneliness is an increasingly recognised determinant of health in older adults, associated with adverse outcomes and higher healthcare utilisation. PURPOSE: This study aimed to evaluate the relationship between loneliness and healthcare use in an ageing rural population in southern Portugal.
methodsA cross-sectional survey was conducted amongst community-dwelling individuals aged ≥ 65 years, randomly selected from primary care records in the Baixo Alentejo region. Data collection included the validated Portuguese version of the UCLA Loneliness Scale and self-reported use of healthcare services over the previous year (primary care and emergency visits, and the number of daily prescribed medicines).
resultsA total of 318 participants were included (58.8% female), with a mean age of 75.5 years, 28.9% over 80. Mild loneliness was reported by 52.2% and severe loneliness by 14.8%. Severe loneliness was significantly associated with increased primary care visits (OR = 6.8; 95%CI: 5.8-7.7; p < 0.001), emergency department use (OR = 5.8; 95%CI: 4.4-7.1; p < 0.001), and polypharmacy (OR = 2.0; 95%CI: 1.3-2.6; p < 0.001). Depression, poor perceived health, family dysfunction, and urinary tract disease were associated with severe loneliness, whilst strong neighbourhood relationships appeared protective.
conclusionLoneliness is a measurable and clinically relevant determinant of healthcare use in older adults. These findings support the integration of loneliness screening and intervention into routine clinical care, regardless of geographic setting.
