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

backgroundPatients are offered implantable defibrillators (ICDs) for the prevention of sudden cardiac death (SCD). However, patients' decision-making process (DMP) of whether or not to accept an ICD has not been explored. We asked patients about their decision making when offered an ICD. DESIGN/

settingA grounded theory methodology was employed. Patients were recruited from three ICD centres. Those who received an ICD underwent interviews the first month after implant. Declining patients had interviews at their convenience. In-depth analysis of transcripts was completed. Identified themes were placed along process pathways in a DMP model and tested.

findingsForty-four patients consented to participate (25% women). Thirty-four accepted an ICD and 10 (23%) declined. Ages ranged from 26 to 87 (mean = 65; SD = 12.5). Participants were retired (65%), had ischaemic heart disease (64%) and some post-secondary education (52%). The DMP was triggered when patient's risk for SCD was communicated. The physician's recommendation and a new awareness SCD risk were motivators to accept the ICD. Patient's decision-making approaches fell along a continuum, from active and engaged to passive and indifferent. Patient's approaches were influenced most by the following: (i) trust; (ii) social influences and (iii) health state.

conclusionsHealth-care providers need to recognize the DMP pathways in which ICD candidacy and SCD risk are understood. The factors that influence a patient's decision warrant discussion pre-implant. It is imperative that patients comprehend the meaning of ICD candidacy to make an informed decision. Participants did not recall alternatives to receiving ICD therapy.
