ASA Physical Status/ASA Classification

This class is intended to include only patients that are in an extremely poor physical state. The cases were designed not to involve emergency, trauma, or pregnancy, respectively. 1995;50:195—9. In 2014, the ASA developed and approved examples for each ASA-Physical Status Classification System class to provide guidelines in determining the appropriate ASA-Physical Status for patients. Hence, the exact reason for this difference can only be speculated. 2022• An assessment of the consistency of ASA Physical Status classification allocation. Rauh MA, Krackow KA. One way to address inappropriate assignments for disease states not included in the ASA-approved examples would be for individual facilities to create their own examples, which are relevant to that facility. American Society of Anesthesiologists physical classification system is not a risk classification system. Further, many of these nonanesthesia care guidelines and regulations use an ASA-Physical Status assignment of I or II as criteria for nonanesthesia care. In-hospital deaths following elective total joint arthroplasty. Vinta, Charles F. These data trends are similar to those observed nearly five decades ago in a landmark study evaluating the association between ASA PS and 48-h surgical mortality on adult men at US naval hospitals. 1, and significance was assessed at the 0. KR participated in the study design and helped to draft the manuscript. Saklad M. ASA 1: No organic pathology or patients in whom the pathological process is localized and does not cause any systemic disturbance or abnormality. One hundred seventy-one nonanesthesia-trained respondents participated in the study, with 110 nonanesthesia-trained respondents completing the questionnaire, for a 64. The correct ASA-Physical Status for each hypothetical case was previously determined by consensus among the investigators using objective interpretation of the definitions of ASA-Physical Status Classification System and the ASA-approved examples. For anesthesia-trained, mean number of correct answers significantly improved with the addition of examples compared to definitions alone. A combination of cardiovascular-renal disease with marked renal impairment. She admits to smoking two to three cigarettes a day, which is down from her usual one-half pack a day; she has been smoking for the past 30 yr. The Creative Commons Public Domain Dedication waiver applies to the data made available in this article, unless otherwise stated. As previously mentioned, the assignment of a correct ASA-Physical Status may be viewed as overreaching. However, with examples, nonanesthesia-trained clinicians improved more compared to anesthesia-trained clinicians. et al. Data were verified for accuracy and completeness by dedicated quality control nurses at each site and electronically transferred to a centralized database. ASA 4: Extreme systemic disorders which have already become an eminent threat to life regardless of the type of treatment. However, the risk of 48-h mortality following an anesthetic was significantly lower in the contemporary cohort when compared with that in the historical cohort for patients undergoing elective procedures. Does the Current ASA Physical Status Classification Represent the Chronic Disease Burden in Children Undergoing General Anesthesia? A public web portal that utilized SurveyMonkey Internet-polling software was created to allow respondents to complete the questionnaire in an anonymous manner. The ASA-Physical Status Classification System is also used by nonanesthesia-trained clinicians and others. Comorbidities from ASA-approved examples listed for each case. 2022. Anaesthesia 2019; 74:373-9• Hurwitz: Department of Anesthesiology and Pain Management, University of Texas Southwestern Medical Center, 5323 Harry Hines Blvd, Dallas, Texas 75390. She has a history of uncontrolled hypertension in the past leading to end-stage renal disease ESRD. AcronymFinder. Case 2 A 53-yr-old woman presents for bilateral breast augmentation. Differences in 48-h mortality between the two cohorts were compared by elective and emergent status via exact binomial tests and within ASA PS using exact chi-square tests followed by the Hochberg multiple comparison correction. The QCNS system collects comorbidities, anesthetic and procedural information, and outcomes in a homogeneous fashion using a standard set of elements across the entire set of participating sites for every case. Functional capacity IIb. Her most recent hemoglobin A1c is 10. American Society of Anaesthesiologists Physical Status classification. MSS participated in study design and helped to draft the manuscript. Number of respondents in each category shown. Risk factors for surgical site infection after elective resection of the colon and rectum: a single-center prospective study of 2,809 consecutive patients. Furthermore, the QA process for the Quantum database is robust. The American Society of Anesthesiologists Physical Status ASA PS Classification System CS , introduced in 1941, is routinely assigned to patients prior to procedures where an anesthesia professional is present, and application of this system has become a standard component of anesthetic practice worldwide Gawande et al. Conclusions The association between increasing ASA PS designation 1—5 and mortality within 48 h of surgery is significant for patients undergoing both elective and emergent procedures in a contemporary dataset consisting of over 700,000 patient encounters. This study shows that data from a large, contemporary, multi-institutional, cohort reaffirm the association between increasing ASA PS designation and increased mortality within 48 h of an anesthetic for both elective and emergent procedures was initially established more than five decades ago. 05 level. Anesth Analg. Skaga NO, Eken T, Sovik S, Jones JM, Steen PA. Only respondents who completed the questionnaire in its entirety were used in analysis, for a total of 889 anesthesia-trained and nonanesthesia-trained respondents combined. On the day of surgery, his potassium is 5. All cases had a statistically significant increase in the number of correct answers with the use of definitions and examples, except for case 2. 0001 but not significantly lower among those undergoing emergent procedures 1. With examples, anesthesia-trained 7. Attribution This work is attributed to the Department of Anesthesiology at Duke University Hospital Meetings presented None. It is possible that respondents had a motivation to participate making them different than nonresponders. 0001 and an overall 48-h mortality rate among patients undergoing elective procedures that was significantly lower than that among patients undergoing emergent procedures 0. Meyer Saklad, MD, d. , Barbeito, A. "ASA PS. The ASA-approved examples specify that ESRD on regular dialysis constitutes an ASA-Physical Status III. J Am Coll Surg. Published : 20 October 2016• However, there have been concerns that the ASA-Physical Status designations are somewhat subjective and that interrater reliability is suboptimal. This latter observation is especially relevant because understanding perioperative mortality risk can significantly impact management of risk tolerance in a value-based medicine environment that focuses on improving the cost effectiveness of care for the population. They were then given the same 10 hypothetical cases in a different order and asked to assign the ASA-Physical Status, the second time using both the definitions and the newly ASA-approved examples. In addition, anesthesia-specific risks may have changed over time as several new monitoring technologies are available and the pharmacokinetics of newer induction and maintenance agents may portend safer anesthesia options than those used in the 1960s. Data were collected and analyzed from consecutive QA forms for anesthetics delivered to patients between January 2009 and December 2014 at all clinical sites. MC provided statistical and analytics support and helped draft the manuscript. She has never had surgery. Hurwitz EE, Simon M, Vinta SR, et al. Hospital costs and severity of illness in three types of elective surgery. Nurses experienced a greater improvement in mean correct score with the addition of examples as compared to nonanesthesiology-trained physicians ; Supplemental Digital Content, Table,. Despite its widespread use, the ASA-Physical Status Classification System has been criticized due to its subjective nature and lack of interrater reliability when used to evaluate hypothetical cases and in clinical practice. Anesthesiol. 2 7. 9 Nonanesthesiologist physicians 69 5. She has hypertension controlled on metoprolol. Associations between ASA Physical Status and postoperative mortality at 48 h: a contemporary dataset analysis compared to a historical cohort. 2015;120 2 :364—70. She is currently compliant with her hemodialysis three times per week. With definitions and examples, this increased to 7 of 10 cases for anesthesia-trained and 8 of 10 cases for nonanesthesia-trained respondents. The anesthesia department is now the very best hospital department in our entire facility. 2001;234 2 :181—9. in 1970. Furthermore, as is the case with any large, retrospective database analysis, it is possible that data collected at the point of care may not accurately reflect patient characteristics or patient outcome. 2004;63:841—6. Case 5 An 82-yr-old man presents for cataract surgery. com 3 Apr. Johnstone, MD, professor of anesthesiology at West Virginia University in Morgantown, noted that the investigation confirms that adding examples improves the consistency of judging patient physical status. These are real scientific discoveries about the nature of the human body, which can be invaluable to physicians taking care of patients. Mayhew D, Mendonca V, Murthy BVS. This problem can be ameliorated, a recent study has found, with the use of ASA-approved class-specific examples, which help anesthesia and nonanesthesia providers alike substantially increase their ability to determine the correct ASA class Table 1. No other significant medical history is obtained, and on examination, she is within normal limits. Thus, it is possible that repeat patients could have skewed the results of the study. Anesthesia-trained respondents include physician anesthesiologists, resident and fellow anesthesiologists, nurse anesthetists, and anesthesiologist assistants. 2022. While we are limited to speculation, it is possible that the combination of several comorbidities such as asthma, obesity, OSA, gastroesophageal reflux disease, and epilepsy present in this case may have been perceived as sufficient for ASA-Physical Status III using definitions alone. 2004;27:407—11. To maintain consistency with the historical cohort from the landmark study performed by Vacanti et al. BJA. Address correspondence to Dr. Any could be correct. 100. 2001;94:378. Additionally, the overall mortality rate at 48 h was significantly higher among patients undergoing emergent compared to elective procedures in the large contemporary cohort 1. 05 was considered statistically significant with all pairwise comparisons adjusted for multiple comparisons using Bonferroni method. Anaesthesia. Hirsch JA, Leslie-Mazwi TM, Barr RM, McGinty G, Nicola GN, Patel AB, Manchikanti L. Daabiss M. The classification system alone does not predict the perioperative risks, but used with other factors eg, type of surgery, frailty, level of deconditioning , it can be helpful in predicting perioperative risks. Statistics Incident death within 48 h of procedure was cross-tabulated by ASA PS status separately for elective and emergent procedures. This was followed by pairwise comparisons between definitions and examples as well as between anesthesia-trained and nonanesthesia-trained groups. Patients who must have anesthesia to arrest a secondary hemorrhage where the patient is in poor condition associated with marked loss of blood. 0 International License , which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author s and the source, provide a link to the Creative Commons license, and indicate if changes were made. 6 7.

The last time she saw a doctor was for knee pain, but it eventually got better. A 32-yr-old man presents for gastric banding weight loss surgery. In the comparative analysis with the historical cohort that focused on adult males, we found the overall 48-h mortality rate was significantly lower among patients undergoing elective procedures in the contemporary cohort 0. She jogs 4 to 5 miles two to three times a week. The Pediatric Specific American Society of Anesthesiologists Physical Status Score: A Multi-center Study. This trend was observed for patients undergoing both elective and emergent procedures. AB provided analytics and data visualization support and helped to draft the manuscript. When adjusted for multiple corrections, there was no significant difference in performance among individual types of clinicians ; Supplemental Digital Content, Table,. However, with the addition of the newly ASA-approved examples to the definitions, both anesthesia-trained and nonanesthesia trained correctly assigned ASA-Physical Status with a mean of almost 8 of 10 patients. Overall mortality rates in the elective and emergent cases were compared using a two-sided exact binomial test. Hurwitz, Michelle Simon, Sandhya R. Cases were intentionally designed to have focus on patients who would be classified ASA I, II, or III. This case describes a patient with several diseases described as mild or controlled, with an intended correct ASA-Physical Status II. However, unlike the NACOR data files that are heterogeneous in content by design i. ASA Monitor 2015; 79:38-9• 0001. Potential underlying differences in the procedure and patient mix between these two cohorts confound further meaningful analyses of the association between ASA PS and 48-h mortality across different time periods. This increased to 7 of 10 cases with examples. Johnstone added. He has a history of Crohn disease, controlled hypertension, and hyperlipidemia. ; Skaga et al. RG participated in the study design and helped to draft the manuscript. Surgery. Our findings are generally consistent with a recent report from the National Anesthesia Clinical Outcomes Registry NACOR Nunnally et al. Case 8 is another case in which the ASA-Physical Status assignment with the highest overall percentage by respondents differed from what the investigators considered to be the appropriate ASA-Physical Status. She has a 20 pack-years smoking history but quit smoking 5 yr ago and denies any recent respiratory infections. Additionally, as it has been stated that the ASA-Physical Status should not include judgment about operative risk, , we did not examine ASA-Physical Status and operative risk. Assigning a Physical Status classification level is a clinical decision based on multiple factors. American Society of Anesthesiologist Physical Status score may be used a comorbidity index in hip fracture surgery. He has never had surgery and is not on any medications. So, this is a way to see if adding some objectivity can help improve consistency—and I think it does. He has a history of hypertension that is under control on metoprolol and nifedipine. J Bone Joint Surg Br. Table 2. Additionally we have seen a 905 reduction if requested preop lab tests. ; Saklad. Information on purchasing reprints may be found at or on the masthead page at the beginning of this issue. For example, moderate sedation by a nonanesthesia-trained clinician and office-based anesthesia are often limited ASA-Physical Status I and II patients. ; Sauvanet et al. The questionnaire consisted of 10 hypothetical cases, for which respondents were first asked to assign ASA-Physical Status using only the ASA-Physical Status Classification System definitions and a second time using the newly ASA-approved examples. With the method that was used to recruit participants, we are unable to accurately estimate the total number of people invited to participate and thus we cannot report on a true response rate. ASA 5: Moribund patient with little chance of surviving ASA 6: Brain-dead organ donor E Emergency operation Example: An ASA 1 patient having an emergent procedure would be ASA 1E Keyword history• Correct ASA-Physical Status Classification System for cases noted on each column. This climbed to nine of 10 when the examples were added Figure. 2014;113 3 :424—32. , C. However, without objective criteria, the point at which chronic kidney disease migrates from ASA-Physical Status II to III could be left to subjective interpretation of individuals. Urology. Documentation to support this declaration is available upon request. We analyzed only responses for those who completed the survey. To a pediatric anesthesiologist, the presence of hypertension requiring medication in a 9 yr old, even if controlled, may constitute a severe systemic disease and ASA-Physical Status III, whereas there would be little argument against ASA-Physical Status II for the same in an adult. In all groups and all cases, percentage of respondents with correct ASA-Physical Status assignment increased with examples as compared to definitions only. ASA Physical Status Classifications and Examples ASA PS Classification Definition Examples ASA I A normal healthy patient Healthy, nonsmoking, no or minimal alcohol use ASA II A patient with mild systemic disease Mild diseases only without substantive functional limitations. Septic or acute pharyngitis. Hurwitz told Anesthesiology News. Retrieved April 3 2022 from. Department of Anesthesiology, Duke University Hospital, Durham, NC, USA Thomas J. Our data show that with these examples, improvement in the correct assignment of the ASA-Physical Status occurs for anesthesia-trained and nonanesthesia-trained clinicians alike. Perioper Med 5, 29 2016. He is a nonsmoker but has a history of asthma for which he uses albuterol approximately three times per year. Discussion The ASA-Physical Status Classification System has undergone several iterations since its inception as originally proposed by Saklad and in the current form as adapted by Dripps et al. This kind of improvement should help level the playing field between health care providers who often interpret the same clinical situations very differently. Except this time, they were also given a table that included the published examples and again asked to assign an ASA physical status classification. He has type 2 diabetes mellitus, which is poorly controlled. While the Physical Status classification may initially be determined at various times during the preoperative assessment of the patient, the final assignment of Physical Status classification is made on the day of anesthesia care by the anesthesiologist after evaluating the patient. Mortality and morbidity after resection for adenocarcinoma of the gastroesophageal junction: predictive factors. Quality assessments are adjusted for physical status. Bjorgul K, Novicoff WM, Saleh KJ. She has been noncompliant with her continuous positive airway pressure machine due to intolerance of the nasal mask. Uterine rupture. Finally, some insurers pay extra for anesthetics involving higher physical status patients. Results In total, there were 1,029 anesthesia-trained respondents, with 779 anesthesia-trained completing the questionnaire in its entirety, for a 75. The definitions and examples shown in the table below are guidelines for the clinician. Anesthesiology 2017; 126:614-22• 8 and nonanesthesia-trained 8. Complete intestinal obstruction of long duration in a patient who is already debilitated. In addition to demographic and clinical information at the patient level, information on the anesthetizing location, type of providers involved, anesthetic and analgesic techniques, and performance and efficiency indicators such as case cancelation, delay in case starts were collected prospectively, along with several important clinical outcomes within the 48-h period following completion of the procedure. It is not possible to state an absolute measure of severity, as this is a matter of clinical judgment. Hence, problems such as a lack of independent validation of QA sheet data, variable acquisition of data across different information technology platforms, and heterogeneous data definitions are minimized. Of these 306 deaths, 117 occurred among the 232,065 patients that underwent elective surgeries 48-h mortality rate 0. She denies any other end-organ damage related to her hypertension. 100. 8 7. 7 Anesthesiologists 524 5. , Suggested remedies include expansion to a seven-point system to stratify patients with moderate diseases or inclusion of modifiers for states with increased anesthetic considerations, such as pregnancy. 4 SAS Institute Inc. He denies any other problems, and the review of systems is otherwise negative. Compared with the 1960s when 1 in 12 patients with an ASA PS 5E designation died within 48 h of an anesthetic, our study found that 1 in 5 such patients will die within 48 h of anesthetic. Case 4 A 26-yr-old woman presents for ankle open reduction internal fixation after tripping on the sidewalk and fracturing her ankle. Investigators sent invitations to participate in the study and requested in that invitation that the participants help recruit others by distributing the email to their departments or other appropriate contacts. We believe this to be highly unlikely in the QCNS dataset as patient death within 48 h of the procedure is an event that every practitioner filling out the QA form is likely to define similarly and capture accurately within the QCNS system. Correct ASA physical status assignments with and without use of examples. This large difference in outcomes among ASA PS 5E patients may explain the increase in overall 48-h mortality following an anesthetic that was observed for patients undergoing emergent surgery in the contemporary cohort. Current Definitions and ASA-Approved Examples ASA PS Classification Definition Adult Examples, Including, but not Limited to: Pediatric Examples, Including but not Limited to: Obstetric Examples, Including but not Limited to: ASA I A normal healthy patient Healthy, non-smoking, no or minimal alcohol use Healthy no acute or chronic disease , normal BMI percentile for age ASA II A patient with mild systemic disease Mild diseases only without substantive functional limitations. Mild acidosis. Zehm, Sarah M. 8 Anesthesiologist assistants 37 5. Shabot, Abu Minhajuddin, Amr E. 0001. These findings could be related to one or more uncontrolled and potentially confounding variables. 001 comparing definitions only and definitions and examples.。
