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

introductionThis study aimed to examine the patterns and predictors of health service use for people with dementia who self-harmed.

methodsUsing a retrospective linked cohort of people who accessed health services in New South Wales, Australia between 2001 and 2015, we identified 154,811 people with dementia or mild cognitive disorder (the dementia cohort), 28,972 people who self-harmed (the self-harm cohort), and 1541 who had a record of both dementia or mild cognitive disorder and self-harm (the dementia and self-harm subgroup). We examined the rates of health service use (inpatient hospital admissions, emergency department presentations, and mental health ambulatory days) for these cohorts. Using random effects Poisson regression and survival modelling, we investigated the change in and predictors of health service use following self-harm (for those with dementia) or dementia diagnosis (for those who had self-harmed).

resultsPeople with dementia who self-harmed had the highest rate of use of all health services. Ambulatory mental health service use increased after self-harm for people in the dementia cohort, while emergency department and mental health related hospital presentations decreased. Hospitalisations for non-mental health reasons increased after dementia diagnosis for those in the self-harm cohort, but use of other services decreased. Ambulatory mental health service use predicted increased time to re-presentation to hospital. DISCUSSION: Health service use changed after an episode of self-harm for people with dementia. People with dementia with poor mental health or substance use concerns may benefit from more proactive provision of mental health services.
