Summary: This study investigated the comorbidity status of hip fracture patients in Denmark and its impact on prognosis. Over 50% of the patients had moderate to severe comorbidity. Different comorbidity indices produced different results, but showed comparable associations with mortality. These results are important for clinicians to improve prevention and treatment, and for researchers to determine the appropriate comorbidity measure to use.

Summary: Non-elective surgery for thoracic and lumbar fractures is associated with a 7.5% risk of surgical site infection (SSI). Obesity and Elixhauser Comorbidity Index (ECI) are independent predictors of SSI in this population. The study provides a broad overview of the risk of SSI at a national level and may assist in patient counseling.

Summary: This study aimed to describe the morbidity profile of COVID-19 deaths in Portugal during 2020, finding that deaths primarily occurred in individuals aged 80 years or older, with a slightly higher mortality rate in males. The study observed high levels of comorbidities, with varying prevalence rates of zero morbidity and high multimorbidity throughout the year, especially during peak mortality waves.

Summary: The study evaluated the predictive ability of different comorbidity indices for mortality in hip fracture surgery patients. The combination of CCI and Rx-Risk index showed the highest predictive ability, while age and gender alone had lower predictive ability.

Summary: This systematic review and meta-analysis compared the utility of commonly used co-morbidity indices in predicting surgical outcomes. The study included 111 studies with a total of 25,011,834 patients. The results showed that the frailty-based index, mFI-5, outperformed the traditional index, CCI, in predicting short-term mortality and severe complications post-surgically.

Summary: This study analyzed data from patients hospitalized with acute pancreatitis between 2016 and 2019 and found that advanced age, heart disease, renal disease, moderate-severe liver disease, peripheral vascular disease, and cerebrovascular disease were all associated with hospital mortality. Additionally, the Charlson and Elixhauser comorbidity indices were able to predict hospital mortality in patients with acute pancreatitis.

Summary: This study aimed to evaluate the impact of comorbidity on in-hospital mortality (IHM) in peritoneal dialysis patients. Results showed that comorbidity burden, age, gender, and the need for dialysis treatment were predictors of IHM. The study suggests that comorbidity burden should be considered as a predictive factor for IHM in peritoneal dialysis patients with failing dialysis technique.

Summary: This study compared multimorbidity trajectories constructed from different methods and identified low-chronic disease and high-chronic disease trajectories. The models included social determinants of health, such as income, race/ethnicity, and sex differences. Group-based trajectory modeling was used to analyze the data, and all models met statistical diagnostic criteria.

Summary: The objective of this study is to understand the characteristics of multimorbid patients who require hospital care and to predict their rehospitalization and length of stay using machine learning models. The results show that the use of random forest algorithms and direct use of diagnoses codes have better predictive performance. However, the predictive power of the algorithms is limited for length of stay.

Summary: The study compared two prediction models for 30-day mortality after hip fracture surgery, and found that the Charlson Comorbidity Index (CCI) model and the American Society of Anesthesiologists (ASA) model had equal predictive ability. However, the ASA score may be the preferred tool for predicting 30-day mortality after hip fracture.

Summary: This study developed a non-programming and ICD-10 based dataset calculator for calculating Charlson and Elixhauser Comorbidity Index using Microsoft Excel. The results of the calculator were consistent with R- and SAS-based methods, validating its accuracy and reliability.

Summary: This study assessed the performance of APR-DRG's Severity of Illness (SOI) and Risk of Mortality (ROM) in predicting in-hospital mortality compared to Charlson Comorbidity Index (CCI) and Elixhauser Comorbidity Index (ECI) scores. The results showed that the model considering SOI, age, and sex had better discrimination for most APR-DRGs compared to the CCI and ECI models. SOI performed better than ROM in predicting in-hospital mortality. These findings have implications for hospital benchmarking and epidemiological analysis.

Summary: This study aimed to evaluate the clinical association between the age-adjusted Charlson comorbidity index (aCCI) and postoperative mortality in elderly patients. After analyzing the data of elderly patients with hip fractures, it was found that the aCCI was associated with mortality, and the mortality risk increased by 31% when the aCCI increased by one unit.
