1 · What the graph read from it

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.

2 · The registry

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 is associated with greater healthcare use. Still, cost estimates can be biased when shorter survival among severely frail patients is not considered. This study estimated physician service costs across frailty levels, assessing how differential survival influenced expenditures.

methodsIn this retrospective cohort study, 944 older adults received comprehensive geriatric assessment following emergency department (ED) referral to internal medicine. Frailty was measured using the Clinical Frailty Scale (CFS) and categorised as well, mildly frail, moderately frail and severely frail. Publicly funded physician service costs (2015 Canadian dollars[$]) during the subsequent year were obtained from provincial claims. A three-part regression model adjusted for age, sex and illness acuity separated differences attributable to service intensity from those attributable to survival.

resultsParticipants were ED patients (Mage 80.8 years; 521 women [55%]) referred to Internal Medicine; 41.6% died within 1 year. Physician costs were concentrated in the months immediately following ED presentation. Costs for mildly and moderately frail patients were ~ $300-$400 higher than for well patients, although differences were estimated imprecisely. Severely frail patients incurred $704 less than well patients over 1 year, primarily reflecting shorter survival. During periods patients were alive, all frailty groups incurred higher costs than the well group.

conclusionsPhysician service costs varied non-linearly with frailty severity. Lower cumulative expenditure among severely frail patients does not necessarily imply lower healthcare need. Clinical pathways and health-system planning should consider differential survival and use frailty assessment to identify individuals who may benefit from proactive multidisciplinary, supportive or palliative care.
