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

objectivesIn the United States, an estimated 553,000 people are homeless on any given night. Few data provide large-scale, contemporary insight with regard to recent patterns of acute illness in this vulnerable population. We evaluated patterns, causes, and outcomes of acute hospitalization among homeless persons compared with a demographics-standardized and risk-standardized nonhomeless cohort.

methodsRetrospective study comparing 185,292 hospitalizations for homeless individuals and 32,322,569 hospitalizations for demographics-standardized nonhomeless individuals between 2007 and 2013 in Massachusetts, Florida, and California. Annual hospitalization rates for homeless persons were calculated and causes of hospitalization were compared with a demographics-standardized nonhomeless cohort. Logistic and linear regression models were used to estimate risk-standardized outcomes.

resultsFrom 2007 to 2013, hospitalizations for the homeless increased in Massachusetts (294 to 420 hospitalizations per 1000 homeless residents), Florida (161 to 240/1000), and California (133 to 164/1000). Homeless patients were on average 46 years of age, often male (76.1%), white (62%), and either uninsured (41.9%) or insured by Medicaid (31.7%). Hospitalizations for homeless persons, compared with demographics-standardized nonhomeless, were more frequently for mental illness and substance use disorder (52% vs. 18%, P<0.001). Homeless compared with risk-standardized nonhomeless individuals had lower in-hospital mortality rates (0.9% vs. 1.2%, P<0.001), longer mean length of stay (6.5 vs. 5.9 d, P<0.001), and lower mean costs per day ($1 535 vs. $1 834, P<0.001).

conclusionsHospitalizations among homeless persons are rising. Despite greater policy and public health focus over the last few decades, mental illness and substance use remain primary drivers of acute hospitalization among homeless adults. Policy efforts should address barriers to the use of ambulatory care services, and behavioral health services in particular, to help reduce acute care use and improve the long-term health of homeless individuals.
