Objective To explore the predictive value of Charlson comorbidity index(CCI)in the prognosis of aged chronic obstructive pulmonary disease (COPD)patients. Methods A retrospective review was performed for 350 hospitalized aged COPD patients who admitted in Xuanwu Hospital of Capital Medical University from January 2010 to January 2015.The clinical data were recorded including age,body mass index (BMI),comorbidities (CCI score),FEV1%pred,the times of acute exacerbation of COPD a year before admission,and in-hospital mortality.The risk factors of acute exacerbation and in-hospital mortality were analyzed by multivariable logistic regression. Results There were 177 patients who had experienced acute exacerbation more than 2 times per year and 173 patients who had experienced acute exacerbation less than 2 times per year.Multivariable logistic regression analysis showed that CCI [OR=1.559,95% CI(1.309,1.856),P=0.000] and FEV1%pred [OR=0.979,95% CI(0.964,0.994),P=0.006] were the independent predictors for acute exacerbation of COPD.The in-hospital mortality rate was 10.3%(36/314). Multivariable logistic regression analysis showed that CCI [OR＝1.894,95% CI (1.422,2.523),P=0.000],age [OR=1.153,95% CI(1.063,1.251),P=0.001],FEV1%pred [OR=0.916,95% CI(0.878,0.955),P=0.000],BMI [OR=0.849,95% CI(0.749,0.962),P=0.011],acute exacerbation more than 2 times per year [OR=6.340,95% CI(1.469,27.366),P=0.013] were the independent predictors for mortality. Conclusion CCI is an independent risk factor associated with in-hospital mortality and acute exacerbation of COPD.
ObjectiveTo evaluate the prognosis of benign esophageal perforation by Pittsburgh scoring system (perforation severity scores, PSS) combined with co-disease index (Charlson comorbidity index, CCI).MethodsThirty patients with benign esophageal perforation from August 2016 to August 2018 in our hospital diagnosed by imaging or endoscopy were selected, including 14 males and 16 females, aged 68.660±10.072 years. After treatment, we retrospectively analyzed whether there was any complication in the course of treatment, the healing of esophageal perforation at discharge and the follow-up after discharge. And the patients were divided into a stable group (20 patients with no complication, clear healing of esophageal perforation at discharge or death during follow-up) and an unstable condition group (10 patients with complications, esophageal perforation at discharge or death during follow-up). Complete clinical data of all the patients were obtained and were able to be calculated by the scores of PSS and CCI scoring system. The difference of PSS and CCI scores between the two groups was compared, and the clinical value of PSS combined with CCI score in the prognosis of benign esophageal perforation was analyzed.ResultsIn the stable group, the PSS was 2.750±1.372 (95%CI 2.110 to 3.390), CCI score was 2.080±1.055 (95%CI 1.650 to 2.500) with a statistical difference between the two systems (P=0.000). In the unstable group, PSS was 7.300 ±1.829 (95%CI 7.300 to 8.120), CCI was 4.640±1.287 (95%CI 4.220 to 5.060) with a statistical difference between the two systems (P<0.05). The area under the receiver operating characteristic curve of PSS and CCI scores in the prognostic evaluation of benign esophageal perforation was 0.982 and 0.870 respectively, which was statistically significant (P<0.05).ConclusionEsophageal perforation is a dangerous condition. It is of great practical value to evaluate the condition of esophageal perforation by PSS and CCI scores.
ObjectivesTo compare the efficacy of acute physiology and chronic health evaluationⅡ (APACHEⅡ), national early warning score (NEWS), pulmonary embolism severity index (PESI) and Charlson comorbidity index (CCI) on pulmonary embolism (PE) prognosis.MethodsClinical data of patients with PE treated in The Second Xiangya Hospital of Central South University from 2010 to 2017 were retrospectively analyzed. They were divided into death group and survival group, and four clinical scores were calculated. The differences of risk factors between the two groups were compared. Logistic regression analysis was used to obtain the independent risk factors related to mortality. The ROC working curve was used to compare the capability of four clinical scores for PE mortality. SPSS 24.0 and Medcalc 18.2.1 software were used for statistical analysis. ResultsA total of 318 patients with PE were included, and the mortality rate was 13.2%. The APACHEⅡ, NEWS, PESI and CCI of the death group were higher than those of the survival group. There were significant differences between two groups (P<0.05). It was confirmed by logistic regression analysis that cerebrovascular disease, heart rate, leukocyte, troponin T, arterial partial pressure of oxygen, right ventricular dysfunction (RVD) were independent risk factors for 90-day mortality. The areas under the ROC curve of APACHEⅡ, CCI, PESI, NEWS were 0.886, 0.728, 0.715 and 0.731, respectively. The area under the ROC curve of APACHEⅡ was the largest, which was better than NEWS, CCI and PESI (P<0.05), and there was no significant difference among NEWS, CCI and PESI.ConclusionsAPACHEⅡ may be the best predictor of mortality in PE patients, which is superior to NEWS, CCI and PESI.
Objective To investigate the relationship between age-adjusted Charlson comorbidity index (aCCI) and ischemic stroke in patients with ophthalmic artery occlusion (OAO) or retinal artery occlusion (RAO). MethodsA single center retrospective cohort study. Seventy-four patients with OAO or RAO diagnosed by ophthalmology examination in Shenzhen Second People's Hospital from June 2004 to December 2020 were included in the study. The baseline information of patients were collected and aCCI was used to score the patients’ comorbidity. The outcome was ischemic stroke. The median duration of follow-up was 1 796.5 days. According to the maximum likelihood ratio of the two-piecewise COX regression model and the recursive algorithm, the aCCI inflection point value was determined to be 6, and the patients were divided into low aCCI group (＜6 points) and high aCCI group (≥6 points). A Cox regression model was used to quantify the association between baseline aCCI and ischemic stroke. ResultsAmong the 74 patients, 53 were males and 21 were females, with the mean age of (55.22±14.18) (19-84) years. There were 9 patients of OAO and 65 patients of RAO. The aCCI value ranges from 1 to 10 points, with a median of 3 points. There were 63 patients (85.14%, 63/74) in the low aCCI group and 11 patients (14.86%, 11/74) in the high aCCI group. Since 2 patients could not determine the time from baseline to the occurrence of outcome events, 72 patients were included for Cox regression analysis. The results showed that 16 patients (22.22%, 16/72) had ischemic stroke in the future. The baseline aCCI in the low aCCI group was significantly associated with ischemic stroke [hazard ratio (HR)=1.76, 95% confidence interval (CI) 1.21-2.56, P=0.003], and for every 1 point increase in baseline aCCI, the risk of future ischemic stroke increased by 76% on average. The baseline aCCI in the high aCCI group had no significant correlation with the ischemic stroke (HR=0.66, 95%CI 0.33-1.33, P=0.247). ConclusionsaCCI score is an important prognostic information for patients with OAO or RAO. A higher baseline aCCI score predicts a higher risk of ischemic stroke, and the association has a saturation effect.
ObjectiveTo observe the effect of comorbidity for patients with non-small cell lung cancer (NSCLC) on exercise tolerance and cardiopulmonary function. MethodsNSCLC patients who underwent cardiopulmonary exercise testing (CPET) before surgery were retrospectively included. According to the Charlson comorbidity index (CCI) score, patients were divided into two groups: a CCI≥3 group and a CCI＜3 group. The patients were matched with a ratio of 1 : 1 by propensity score matching according to the age, body mass index, sex, smoking histology, exercise habits, pathological stage and type of surgery. After matching, CPET indexes were compared between the two groups to explore the differences in exercise tolerance and cardiopulmonary function. ResultsA total of 276 patients were included before matching. After matching, 56 patients were enrolled with 28 patients in each group, including 38 (67.9%) males and 18 (32.1%) females with an average age of 70.7±6.8 years. Compared with the CCI＜3 group, work rate at peak (WR peak), WR peak/predicted (WR peak%), kilogram oxygen uptake at anaerobic threshold (VO2/kg AT), VO2/kg peak, VO2/kg peak%, peak carbon dioxide output (VCO2 peak), the minute ventilation to carbon dioxide production slope (VE/VCO2 slope), O2 pulse peak and O2 pulse peak% of CCI≥3 group were statistically different (P＜0.05). Among them, the rate of postoperative pulmonary complication in the CCI≥3 group was higher than that in the CCI＜3 group (60.7% vs. 32.1%, P=0.032). ConclusionIn the NSCLC patients, exercise tolerance and cardiopulmonary function decreased in patients with CCI≥3 compared with those with CCI<3. CPET can provide an objective basis for risk assessment in patients with comorbidity scored by CCI for pulmonary resection.
