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

backgroundCommunity health worker (CHW) interventions can improve health outcomes and reduce acute care utilization. Few prior studies have examined the association of CHW interventions with health care utilization among patients within an integrated health system.

objectiveTo evaluate the effects of Individualized Management for Patient Centered Targets (IMPaCT), a standardized CHW intervention originally developed within a single health system in Philadelphia, PA, on acute care utilization and primary care engagement among low-income patients at two clinics within an integrated health system in Portland, Oregon.

designProspective randomized analysis using adjusted difference-in-differences regression.

participantsIn total, 1230 adults living in low-income zip codes were randomized using a 2:1 allocation sequence to receive either IMPaCT (n = 820) or usual care (n = 410).

interventionsIMPaCT is a standardized intervention in which CHWs use an in-depth interview to understand patients' strengths, social needs, and health-related goals and then collaboratively develop tailored action plans. Over 3 months, CHWs communicated with patients at least once weekly to provide coaching, social support, and navigation tailored to their goals. Due to the COVID- 19 pandemic, the intervention was predominantly delivered remotely. MAIN MEASURES: Primary outcome measures were hospital and emergency department (ED) utilization, both measured per 1000 members per month, and proportion of patients with 1+ primary care visits. Implementation fidelity and maintenance were also assessed. KEY

resultsCompared to usual care, patients who received IMPaCT had a relative reduction in total hospital days at 6 months (- 172.3 days per 1000 members per month, 95% CI - 320.05 to - 24.53, p= 0.022), and a greater proportion attended 1+ primary care visits (85.7% vs. 79.5%, p= 0.006). There were no differences in ED utilization.

conclusionsA standardized CHW intervention delivered remotely within an integrated health system during the COVID- 19 pandemic was associated with decreased hospital utilization and improved primary care engagement.
