Mortality Prediction in a Vertebral Compression Fracture Population: the ASA Physical Status Score versus the Charlson Comorbidity Index

Abstract

Background Morbidity and mortality scores are useful to control for medical comorbidities in study populations where either effects of an illness or benefits of a treatment are examined. Our study examined if a direct relationship existed between the American Society of Anesthesiologists Physical Status (ASA) score and the Charlson Comorbidity Index (CCI) in an osteoporosis population where patients had sustained a vertebral compression fracture.

Effect of Preoperative Medical Status on Microsurgical Free Flap Reconstructions: A Matched Cohort Analysis of 969 Cases

“…17 Correlations between ASA scores and postoperative morbidity and mortality are often inconclusive. [17][18][19][20][21][22][23] While several studies demonstrated a close relation to the ASA score and morbidity, mortality, operating times, length of hospitalization, postoperative complications, health care costs, and different other variables, 17,18,[20][21][22][23] other studies were not able to confirm these findings. 19 In an era of fixed fees and rising economic pressure in worldwide health care systems, it becomes increasingly important to establish well-supported indications to perform complex surgeries, such as microsurgical free flap reconstructions.…”

“…3,4,[9][10][11][12][13][14][15] However, while well established in other surgical specialties, few studies have solely focused on the potential effect of the preoperative medical state of the patients as one possible factor influencing the outcome of free flap reconstructions. 16 The preoperative medical status is normally assessed and classified according to the American Society of Anesthesiologists (ASA) score of physical status 11,17,18 which was introduced by Rovenstein, Saklad, and Taylor in 1941 as a grading system for the surgical patients' preoperative health. 17 In 1963, the ASA score was modified to its current form.…”

Perioperative, short-, and long-term mortality related to fixation in primary total hip arthroplasty: a study on 79,557 patients in the ­Norwegian Arthroplasty Register

“…We did not find such a difference, even in the high-risk subgroup or in the group of patients with THA in the course of a hip fracture. However, we adjusted for comorbidity by ASA class, whereas Garland et al adjusted by modified Charlson Comorbidity Index, which may have slightly different effect (Lavelle et al 2015).…”

Improved treatment decisions in patients with esophageal cancer

“…In the current study, ASA score was used for the assessment of comorbidity instead of the Charlson comorbidity index, in order to evaluate the functional impact of other diseases than the index cancer. The ASA score is widely used to describe preoperative physical status, but also to describe comorbidity [23,24]. A recently published study has shown agreement between the ASA score and Charlson comorbidity index score [23] indicating that both systems are applicable for the assessment of comorbidity.…”

“…The ASA score is widely used to describe preoperative physical status, but also to describe comorbidity [23,24]. A recently published study has shown agreement between the ASA score and Charlson comorbidity index score [23] indicating that both systems are applicable for the assessment of comorbidity. Due to the limited number of patients, comparison of survival based on the different treatment regimens was not possible.…”
