Frailty Assessed Using the FRAIL-NH Scale and its Associations with Long-Term Care Needs in Residents of Japanese Nursing Homes: A Multicenter Cross-Sectional 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
Introduction: Frailty is often considered a pre-disability overall health state. However, even among older adults with disability, assessing frailty can be crucial for providing appropriate support and care services that maintain or promote their remaining independent abilities. The FRAIL-NH scale was developed to assess frailty in nursing home residents and has been shown to be useful in predicting their prognosis. We aimed to determine the prevalence and degree of frailty assessed by the FRAIL-NH scale among nursing home residents in Japan and investigate the associations between frailty status and long-term care (LTC) needs. Methods: A cross-sectional study was conducted in four nursing homes in the Tokyo metropolitan area of Japan, 2020. Frailty status was assessed using the 7-item FRAIL-NH scale Japanese version: non-frail (0-1 points), frail (2-5 points), and most-frail (6-14 points). Levels of LTC needs at the latest LTC needs certification were obtained from electronic health records. Age- and sex-adjusted multivariable logistic regression analyses were conducted to evaluate the associations between frailty status and the level of LTC needs. Results: Among 372 residents, 20.7% and 69.9% were frail and most-frail, respectively. Adjusted odds ratios (95% confidence intervals) for being either frail or most-frail were 3.62 (1.31-10.01) and 3.69 (1.14-11.94) for LTC needs levels 4 and 5, respectively, compared to level 3. Similarly, adjusted odds ratios (95% confidence intervals) for most-frail were 3.09 (1.77-5.38) and 6.38 (3.13-13.03) for LTC needs levels 4 and 5, respectively. Conclusions: Most nursing home residents were assessed as being frail or most-frail. Frailty was strongly associated with LTC needs, indicating important resource implications for care services. Moreover, assessing frailty with the FRAIL-NH scale may support medical and care-related decision-making.
