Long-Term Outcomes Associated With Peripheral Nerve Blocks for Hip Fracture Surgery: A Retrospective Comparison of Medicare Data.
Article in Journal of the American Geriatrics Society, 2026. 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
backgroundPeripheral nerve blocks (PNBs) are increasingly recommended as analgesia for hip fractures. Their association with outcomes beyond the immediate pharmacological effects remains unclear. This study examined the association between the use of PNBs and the number of days alive and at home after hip fracture surgery among Medicare beneficiaries.
methodsTo examine the association between PNBs and long-term outcomes in older adults undergoing surgical fixation for hip fractures, we analyzed Medicare data from 2010 to 2018. Patients who received PNBs (exposure group) (n = 5701) were compared to those who did not receive a PNB (comparator group) using 1:1 propensity score matching, creating 5700 matched pairs. The primary outcome was days alive and at home within 120 days of admission. Secondary outcomes included days alive and at home within 365 days and 1-year mortality. A subgroup analysis of propensity score matched patients from 2018 examined outcomes when techniques had improved and use had increased.
resultsIn the primary analysis (2010-2018), no significant differences were observed between groups for days alive and at home within 120 days (68.1 vs. 68.4 days; p = 0.64), days alive and at home within 365 days (244.5 vs. 240.7 days; p = 0.12), or 1-year mortality (21% vs. 22%; p = 0.22). In 2017 and 2018, when peripheral nerve block use increased, patients who received PNBs spent more days alive and at home within 365 days than patients who did not receive peripheral nerve blocks (248.6 vs. 241.6 days; p = 0.04).
conclusionPNBs showed no association with improved outcomes across the 2010-2018 study period. Analysis of 2017 and 2018 revealed more days alive and at home within 365 days and a trend toward reduced mortality among patients who received PNBs. PNBs may provide benefits beyond their immediate analgesic effects, potentially improving long-term outcomes.
