Out-of-hospital cardiac arrests in Swedish nursing homes: occurrence, treatment, and survival compared to private residences.
Article in Scandinavian journal of trauma, resuscitation and emergency medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
backgroundIn Sweden, most out-of-hospital cardiac arrests (OHCAs) occur in private residences and nursing homes. Although studies suggest that nursing home staff appear hesitant to start cardiopulmonary resuscitation (CPR) before ambulance staff arrive, it is unknown whether treatment and outcomes among those who suffer OHCA in nursing homes differ from private residences. The aim of the study was to describe OHCA occurrence, treatment, and 30-day survival in people aged 65 years or older in Swedish nursing homes, in comparison with private residences.
methodsThis retrospective registry study utilized data from the Swedish Register of Cardiopulmonary Resuscitation from 1992 to 2022. The study included 59 459 OHCAs. Data were analyzed using descriptive and inferential statistics, complemented with generalized linear models.
resultsThe number of OHCAs was 56 379 in private residences and 3 080 in nursing homes. While the occurrence of OHCA increased in private residences it remained stable in nursing homes. The overall survival rate in people suffering OHCA in living facilities was 4.4% during the 31-year study period. There was an advantage of 1.0% in 30-days survival for private residences in the unadjusted analyses (p < 0.001), while the adjusted longitudinal model displayed a positive trend in annual survival odds in both private residences (5.6%) and in nursing homes (3.5%), with no difference between the groups (p = 0.207).
conclusionsIn this registry study, 30-day survival in nursing homes and private residences was similar and improved in both settings. These findings suggest that the location of OHCA is not the primary determinant of survival. Resuscitation decisions should be guided by careful consideration of the patient's medical condition, frailty, and personal preferences. Future initiatives might include strengthening emergency preparedness in nursing homes while supporting ethically justified and patient-centred shared decision-making.
