Comparing Two Frailty Tools for the Prediction of Mortality in Older People Admitted to Hospital in Tanzania: A Prospective Cohort Study.

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
Background: Healthcare systems in low- and middle-income countries are under pressure to adapt services for ageing populations, and frailty screening has gained interest as a means of identifying older adults at risk of adverse outcomes. Aims: The aim of this study was to examine two frailty instruments for the prediction of mortality in older adults admitted to hospital in Tanzania. Methods: This study followed 308 people, aged ≥ 60 years, admitted to four hospitals in the Kilimanjaro Region between March and August 2022. Baseline frailty was assessed using the Clinical Frailty Scale (CFS) and the Brief Frailty Instrument for Tanzania (B-FIT). The primary outcome was all-cause mortality, with secondary outcomes of length of stay and change in functional status. Cox regression estimated hazard ratios (HRs) for mortality, with Harrell's C statistic and receiver operator characteristics used to compare instrument performance. Results: Follow-up data were available for 194 participants (63%). After a mean of 10.8 months of follow-up, adjusted models demonstrated frailty was associated with higher mortality (CFS HR 2.26, 95% CI 1.34-3.83; B-FIT HR 2.63, 95% CI 1.45-4.77, Conclusions: Frailty screening, using either the CFS or B-FIT, offered a feasible method for identifying older adults at the greatest risk of adverse outcomes. Such tools should be investigated as a means of targeting limited resources towards the most vulnerable older adults in an African setting.
