National Norms for Hospital Frailty Risk Score Among Hospitalized Adults in the USA.
Article in Journal of general internal medicine, 2025. 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
backgroundFrailty among inpatients increases risk for hospital-associated disability and death. Yet, frailty is not regularly screened in acute care due to the lack of standardized methods, the complexity of frailty, and time and energy required of hospital personnel. Thus, screening with routinely collected data provides an opportunity to assess frailty across inpatient populations.
objectiveTo calculate normative values for Hospital Frailty Risk Score (HFRS) among adult inpatients in the USA based on age, sex, and race.
designA retrospective cross-sectional analysis of the 2018 National Inpatient Sample (NIS) database. PATIENTS: US adult inpatients aged 18y + with a focus on patients aged at least 45. MAIN MEASURES: Hospital Frailty Risk Score (HFRS) is a validated measure that uses ICD-10 codes to calculate frailty risk among hospitalized patients. KEY
resultsMean HFRS significantly increased with increasing age across sex and race (p < 0.001). Among the oldest age groups 65y + , mean and median normative values were similar between male and female inpatients (mean HFRS range, 6.71-9.62; median HFRS range, 5.40-8.70), and Black inpatients had the highest frailty risk compared to other races (mean HFRS range = 7.56-10.47; median HFRS range = 6.30-9.50). Asian/Pacific Islander inpatients had similar frailty risk to Black inpatients among those 90y + (mean HFRS = 10.48; median HFRS = 9.50).
conclusionsThe US national norms for HFRS provide a standardized reference tool for comparing frailty risk among clinical and research inpatient populations to a typical hospitalized adult for their age, sex, and race.
