• #1 Carbon monoxide poisoning – UpToDate

  https://www.uptodate.com/contents/carbon-monoxide-poisoning

  Carbon monoxide poisoning is estimated to occur in 50,000 people annually in the United States, and non-fire-related smoke inhalation is responsible for most cases. Analysis of aggregated national data from the United States supports an overall mortality of 1 to 3 percent, with a mortality rate that is higher for intentional poisoning than for inadvertent exposure. There are approximately 1000 to 1300 deaths from CO poisoning annually. Intentional CO poisoning accounts for two-thirds of deaths and inadvertent, non-fire related CO poisoning cause the rest. […] Myocardial ischemia is common among moderately to severe CO-poisoned patients and is associated with increased long-term mortality. A retrospective study of 230 patients with moderate or severe CO poisoning referred to a specialized center found evidence of myocardial ischemia (characteristic electrocardiographic changes or elevated serum cardiac biomarkers) in one-third of all cases.

• #2 A scoring system with high predictive performance for poor outcomes in acute carbon monoxide poisoning | Scientific Reports

  https://www.nature.com/articles/s41598-025-98162-1

  Carbon monoxide (CO) poisoning causes significant mortality and hypoxic brain injury. […] A model for predicting outcomes early after hospital admission is crucial for guiding care and early rehabilitation. […] Predictors of poor outcomes included age, GCS13, burns and low C-reactive protein levels. […] The ABCG score accurately predicts poor outcomes in acute CO poisoning and supports early intervention and treatment planning. […] This study aimed to develop and validate a practical and reliable scoring model to predict poor outcomes in cases of acute CO poisoning, facilitating better early intervention and optimised treatment strategies. […] Multivariable logistic regression analysis identified age (odds ratio [OR] 1.04, 95% CI 1.01-1.07, P=0.003), presence of burns (OR 3.99, 95% CI 1.51-11.11, P=0.006), GCS13 (OR 4.62, 95% CI 2.63-8.68, P<0.001), and CRP level (OR 1.66, 95% CI 1.19-2.52, P=0.006) as independent predictors of poor outcomes.

• #3 Prognostic factors of carbon monoxide poisoning in Taiwan: a retrospective observational study

  https://pmc.ncbi.nlm.nih.gov/articles/PMC6886984/

  To identify the risk factors related to the prognosis of carbon monoxide (CO)-poisoned patients in the hospital. […] The logistic regression analysis confirmed that the Glasgow Coma Scale (GCS) score (p=0.008) and blood urea nitrogen (BUN) (p=0.002) were related to poor outcomes. Furthermore, the receiver operating characteristic (ROC) curve showed that the cut-off point of intubation days was 1.5 days (area under the ROC curve [AUC]=0.793) for all patients and 2.5 days (AUC=0.817) for patients with intubation when predicting poor outcomes. […] We identified the factors that most strongly predict the prognosis of CO poisoning, including the GCS score, serum BUN and intubation days. Moreover, the number of hyperbaric oxygen treatments seems to have impact of the outcome. […] Patients with poor outcomes were older than those who did not have poor outcomes (p0.001).

The results show that the AUC was around 0.7570.817 in all patients and in intubated patients. […] Our data revealed that patients exposed to CO intentionally have a significantly worse treatment outcome than those by accident. […] The factors best at predicting outcomes were a high GCS score, high BUN and more intubation days.

  https://emedicine.medscape.com/article/819987-overview

  Considerations regarding prognosis include the following: Variability of clinical severity, laboratory values, and outcome limits prognostic accuracy. Cardiac arrest, coma, metabolic acidosis, and high HbCO levels are associated with poor outcome. Abnormal computed tomography (CT) or magnetic resonance imaging (MRI) scan findings are associated with persistent neurologic impairment. Neuropsychiatric testing may have prognostic efficacy in determining delayed sequelae. […] A study by Ahn et al using the National Health Insurance Service (NHIS) of Korea database found evidence for an association between CO poisoning and the development of internal malignancies. According to the investigators, the adjusted hazard ratio (aHR) for solid organ malignancies was 1.03 in persons with CO poisoning. More specifically, the aHRs for malignancies of the oral cavity, lungs, bones, cervix, and kidneys were, respectively, 1.33, 1.39, 1.68, 1.32, and 1.14. On the other hand, the internal malignancy risk was lower for the thorax, anus, uterus, ovaries, and prostate, and for Hodgkin lymphoma, non-Hodgkin lymphoma, and multiple myeloma. The risk of hematologic malignancies was also lower, with the aHR being 0.71. The mean follow-up time for the persons who suffered CO poisoning was 2350.91 days.

  A study by Hwang et al that also used the NHIS of Korea database indicated that CO poisoning is linked to the development of migraine headaches. The aHR for migraine was 1.37, with the risk being greater regardless of age, sex, or HBO therapy use. Mean follow-up for persons with CO poisoning was 5.9 years. […] An analysis of 331 pediatric patients with CO poisoning seen at a single-site emergency department found risk factors associated with severe disease course were a low Glasgow Coma Scale score, high leukocyte count, and high troponin T levels at presentation. Patients with myocardial injury from CO poisoning are at higher risk for short-term mortality, and survivors are at increased risk for neurocognitive sequelae and future myocardial infarction. […] Survivors of intentional CO poisoning are at extreme risk for subsequent completion of suicide.

  https://www.uptodate.com/contents/carbon-monoxide-poisoning

  In patients who survive the initial poisoning, morbidity is primarily related to late neurocognitive impairment and persists in up to 40 percent of victims. Significant CO poisoning may be associated with an increased risk of developing a subsequent seizure disorder. Long-term mortality is increased if CO poisoning causes myocardial injury. Long-term follow-up (median 7.6 years) of a cohort of patients with moderate to severe CO poisoning who sustained acute myocardial injury noted a mortality rate of 24 percent. Mortality among patients with myocardial injury was more than twice that of poisoned patients without evidence of such injury and was estimated to be triple the expected rate for a comparable non-poisoned cohort.

  https://www.nature.com/articles/s41598-025-99887-9

  This study aims to analyse and predict the disease burden of occupational carbon monoxide (CO) poisoning in China and provide recommendations for its prevention and treatment. […] The results show a decreasing trend in age-standardised mortality rate (ASMR) and age-standardised disability-adjusted life years (ASDR) from 2000 to 2021, with male rates consistently higher than female rates. […] The decline in disease burden is likely to be due to advances in medical technology and improved efforts to prevent occupational diseases, but it remains higher than the global average and in several SDI regions. […] Further actions are needed to reduce the burden of occupational CO poisoning, including increasing the coverage of hyperbaric chambers in all regions, improving the efficiency of regulation of small and medium-sized enterprises, and strengthening CO safety training, especially for young male workers in high-risk industries.
