Incidence and Associated Factors for Chronic Pain After ICU Discharge: A Prospective Study.
Article in Nursing in critical care, 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
backgroundSurvivors of critical illness are at high risk for developing chronic pain. However, evidence regarding new-onset chronic pain in this specific population remains limited in China.
aimsThis study aimed to investigate the incidence of chronic pain among Chinese intensive care unit (ICU) survivors at 3 months after discharge and to identify associated factors. STUDY
designThis was a prospective study. The participants were adult ICU survivors from a mixed ICU of a tertiary hospital in Zhejiang, China. The Brief Pain Inventory (BPI) was used to assess pain at 3 months after ICU discharge. Multivariable binary logistic regression was performed to identify factors independently associated with chronic pain.
resultsAmong 328 ICU survivors, 109 (33.2%) reported new-onset chronic pain, including 64 of 109 (58.7%) with mild pain (BPI average pain score 1-3), 42 of 109 (38.5%) with moderate pain (BPI average pain score 4-6) and 3 of 109 (2.8%) with severe pain (BPI average pain score 7-10). The shoulder was the most frequently reported pain site (46 of 109, 42.2%), and normal work was the daily domain most affected by pain. Multivariable analysis showed that pre-existing chronic pain (OR = 4.77, 95% CI: 2.02-11.30, p < 0.001), days with mechanical ventilation (OR = 1.27, 95% CI: 1.17-1.37, p < 0.001), and days with hyperinflammation (OR = 1.34, 95% CI: 1.18-1.53, p < 0.001) were independently associated with the development of new-onset chronic pain. Among 286 patients without pre-existing chronic pain, 79 (27.6%) developed new-onset chronic pain; mechanical ventilation duration and hyperinflammation remained independently associated with this outcome.
conclusionsApproximately one-third of ICU survivors experience chronic pain, with 41.3% reporting moderate-to-severe pain that interfered with daily functioning. These findings highlight the importance of systematic pain assessment and targeted follow-up after ICU discharge. RELEVANCE TO CLINICAL PRACTICE: Post-ICU follow-up should include systematic assessment of chronic pain and pain-related functional impairment alongside other PICS domains, including psychological distress, cognitive dysfunction and physical impairments, to ensure holistic, patient-centred recovery after critical illness.
