ABSTRACT

OBJECTIVE: Frailty is a clinical syndrome associated with slow recovery after vascular surgery. However, the degree and length of functional impairment frail patients experience after surgery is unclear. The objective of this study was to prospectively measure changes in functional status among frail and non-frail patients undergoing a spectrum of different vascular surgery procedures. METHODS: Patients consented to undergo elective minor and major vascular surgery procedures at an academic medical center between May 2018 and March 2019 were prospectively identified. Prior to surgery, all patients underwent provider assessment of frailty using the validated Clinical Frailty Scale (CFS), as well as baseline assessment of functional status using the Katz Activities of Daily Living (ADL) index and the Lawton Instrumental Activities of Daily Living (iADL) index. These same instruments were used to evaluate each patient's functional status at 2-weeks, 1-month, 1-year, and 2-year time points following surgery. Changes in iADL and ADL scores among frail (CFS ≥5) and non-frail patients were compared using paired Wilcoxon signed-rank tests and logistic regression models. RESULTS: A total of 126 patients were assessed before and after minor (55%) and major (45%) vascular procedures, of which 43 patients (34%) were determined to be frail prior to surgery. Frail patients were older and more likely than non-frail patients to have medical comorbidities including chronic kidney disease, chronic obstructive pulmonary disease, or diabetes (all P < .05). When compared with the non-frail cohort, frail patients had significantly lower ADL and iADL scores before surgery and experienced a greater decline in ability to independently complete ADL and iADL activities after surgery that was sustained at 2 years (P < .05 and P < .001, respectively). After risk-adjustment, frailty was associated with an increased likelihood of decline in ADLs (odds ratio, 5.4; 95% confidence interval, 1.9-15.4; P < .05) and iADLs (odds ratio, 6.3; 95% confidence interval, 2.6-15.1; P < .001) at 2 years following surgery. CONCLUSIONS: Frail patients experience a significant decline in ability to perform ADL and iADLs that persists 2 years following vascular surgery. These data highlight the degree of functional decline occurring immediately following surgery, as well as risk for long-term, sustained impairment that should be shared with frail patients before undergoing a procedure.

ABSTRACT

BACKGROUND: Identification of high-risk patients that may experience functional decline following surgery poses a challenge to healthcare providers. The Vulnerable Elders Survey (VES-13) is a patient-reported tool designed to identify risk for health deterioration based on age, self-rated health, physical function, and functional disabilities. This study was designed to determine whether VES-13 could predict long-term functional decline among patients undergoing vascular surgery procedures. METHODS: Vascular surgery patients at an academic hospital were administered VES-13 between May 2018 and March 2019, and those scoring ≥3-points were classified as vulnerable. Each patient's functional status was assessed using the Katz Activities of Daily Living (ADL) and the Lawton-Brody Instrumental Activities of Daily Living (iADL) indices preoperatively and at 2-week, 1-month, and 1-year postoperative time points. Logistic regression models were used to identify independent predictors of functional decline. RESULTS: 126 patients (59% male) were assessed before and after minor (56%) and major (44%) vascular procedures, with 55 (43%) meeting criteria for vulnerability. Vulnerable patients were older, had lower baseline functional status, and were more likely than non-vulnerable patients to experience declines in ADLs and iADLs at all time-points (P < 0.05 for all time points). These findings were confirmed in risk-adjusted regression models where vulnerability was associated with an increased likelihood of decline in ADLs (OR:3.3; 95%CI:1.0-10.6; P < 0.05) and iADLs (OR:2.6; 95%CI:1.0-6.6; P = 0.05) at 1-year following surgery. CONCLUSION: The patient-reported VES-13 survey identifies vulnerable patients who are at risk for long-term functional decline following vascular surgery. This quick preoperative screening tool can allow surgeons to prepare older patients and caretakers for postoperative functional limitations.

ABSTRACT

Importance: International Statistical Classification of Diseases and Related Health Problems, Tenth Revision (ICD-10) codes are used to characterize coronavirus disease 2019 (COVID-19)-related symptoms. Their accuracy is unknown, which could affect downstream analyses. Objective: To compare the performance of fever-, cough-, and dyspnea-specific ICD-10 codes with medical record review among patients tested for COVID-19. Design, Setting, and Participants: This cohort study included patients who underwent quantitative reverse transcriptase-polymerase chain reaction testing for severe acute respiratory syndrome coronavirus 2 at University of Utah Health from March 10 to April 6, 2020. Data analysis was performed in April 2020. Main Outcomes and Measures: The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of ICD-10 codes for fever (R50*), cough (R05*), and dyspnea (R06.0*) were compared with manual medical record review. Performance was calculated overall and stratified by COVID-19 test result, sex, age group (<50, 50-64, and >64 years), and inpatient status. Bootstrapping was used to generate 95% CIs, and Pearson χ2 tests were used to compare different subgroups. Results: Among 2201 patients tested for COVD-19, the mean (SD) age was 42 (17) years; 1201 (55%) were female, 1569 (71%) were White, and 282 (13%) were Hispanic or Latino. The prevalence of fever was 66% (1444 patients), that of cough was 88% (1930 patients), and that of dyspnea was 64% (1399 patients). For fever, the sensitivity of ICD-10 codes was 0.26 (95% CI, 0.24-0.29), specificity was 0.98 (95% CI, 0.96-0.99), PPV was 0.96 (95% CI, 0.93-0.97), and NPV was 0.41 (95% CI, 0.39-0.43). For cough, the sensitivity of ICD-10 codes was 0.44 (95% CI, 0.42-0.46), specificity was 0.88 (95% CI, 0.84-0.92), PPV was 0.96 (95% CI, 0.95-0.97), and NPV was 0.18 (95% CI, 0.16-0.20). For dyspnea, the sensitivity of ICD-10 codes was 0.24 (95% CI, 0.22-0.26), specificity was 0.97 (95% CI, 0.96-0.98), PPV was 0.93 (95% CI, 0.90-0.96), and NPV was 0.42 (95% CI, 0.40-0.44). ICD-10 code performance was better for inpatients than for outpatients for fever (χ2 = 41.30; P < .001) and dyspnea (χ2 = 14.25; P = .003) but not for cough (χ2 = 5.13; P = .16). Conclusions and Relevance: These findings suggest that ICD-10 codes lack sensitivity and have poor NPV for symptoms associated with COVID-19. This inaccuracy has implications for any downstream data model, scientific discovery, or surveillance that relies on these codes.
