Association between hospital frailty risk score, risk of sepsis and adverse outcomes across all adult ages.

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
backgroundHospital Frailty Risk Score (HFRS) is commonly used to identify frailty risk and predict poor outcomes. Frailty and sepsis are associated with poor outcomes. This study aimed to evaluate the association between HFRS, risk of sepsis and poor health outcomes across all adult ages.
methodsA retrospective cohort study analysed data from Queen Alexandra Hospital, a major acute hospital in the UK, covering the period from January 1, 2010, to December 31, 2019. It included patients aged 16 and older. The Hospital Frailty Risk Score (HFRS) was used to identify patients at risk of frailty. The Suspicion of Sepsis (SOS) codes and the National Early Warning Score (NEWS) were used to identify patients at risk of sepsis. Logistic Regression with interaction models were developed to examine the associations between HFRS, risk of sepsis and poor outcomes (length of stay and in-hospital mortality) across all adult ages.
resultsPatients with higher frailty risk and sepsis-risk-positive groups had longer length of stay and higher risk of in-hospital mortality compared to the sepsis-risk-negative groups. Interaction between intermediate or high frailty risk and sepsis-risk-positive (SOS codes present, NEWS≥7, and SOS codes present with NEWS≥7 groups) was significant for all periods of length of stay and all periods of in-hospital mortality (P < 0.001). Moreover, sepsis-risk-positive groups had a greater impact on the predictive power of HFRS to predict long LOS and in-hospital mortality compared to the sepsis-risk-negative groups.
conclusionThis study concluded that there is a strong association between risk of frailty (identified with HFRS), risk of sepsis, and poor outcomes in urgently hospitalised adults of all ages.
