Improving Safety of Bilateral Knee Arthroplasty: Impact of Selection Criteria on Perioperative Outcome

Background: Bilateral total knee arthroplasty (BTKA) procedures are associated with an increased risk of complications when compared with unilateral approaches. In 2006, in an attempt to reduce this risk, our institution implemented selection criteria that specified younger and healthier patients as candidates for BTKA. Questions/Purpose: We sought to investigate the effect of these selection criteria on perioperative outcomes. Methods: In a retrospective cohort study, we used institutional data to identify patients who underwent BTKA between 1998 and 2014. Patients were divided into 2 groups: those who underwent surgery before the 2006 introduction of our selection criteria (1998–2006) and those who underwent surgery after (2007–2014). Groups were compared in terms of demographics, comorbidity burden, and incidence of perioperative complications. Regression analysis was performed, calculating incidence rate ratios to evaluate changes in complication rates. Results: Before the selection criteria were implemented in 2006, patients who underwent BTKA were older and had a higher comorbidity burden. The rate of major complications per 1000 hospital days decreased from 31.5 in 1998 to 7.9 in 2014. A reduction in cardiac complications was the most significant contributor to this decrease in major complications. Conclusion: After stringent criteria for BTKA candidates were implemented at our institution, selection of younger patients with lower comorbidity burden was accompanied by a reduction in the incidence of operative complications. This suggests that introducing such criteria can be associated with a reduction in adverse perioperative outcomes.

498 Background: Surgery for RCC patients with IVC thrombus above the hepatic veins is complex and associated with an increased risk of perioperative morbidity and mortality. However, minimal data exist that describe contemporary perioperative outcomes at major referral centers or the prognostic factors associated with adverse surgical outcomes. The objective of this study is to determine the preoperative predictors of major complications and 90 day mortality after surgery in RCC patients with IVC thrombus above the hepatic veins. Methods: Records were reviewed of all RCC patients with IVC tumor thrombus above hepatic veins who had surgery from 1/2000 to 12/2012 at Mayo Clinic, MD Anderson, UT Southwestern and the University of Wisconsin. Major complications were recorded were defined as 3A or greater according to the Clavien- Dindo system within 90 days of surgery. Univariate and multivariate (MV) analyses were used to evaluate associations of preoperative clinical, pathological or laboratory variables with risk of major complications or 90-day mortality. Results: A total of 162 patients were identified for study (thrombus level 3,4 in 69 and 93 patients, respectively, according to Neves classification). Cardiopulmonary bypass was used in 60/162 (37.5%), while 40 (24.7%) patients underwent pre-operative angioembolization. Major complications were reported in 55 (34.0%) patients, with the most common being respiratory (12.4%), hematologic (9.2%) and cardiac (8.6%). On MV analysis, preoperative systemic symptoms and level 4 thrombus were independently associated with an increased risk of major complications. Mortality was reported in 17 (10.5%) patients within 90 days after surgery. On MV analysis, ECOG performance status and low serum albumin were independently associated with increased risk of 90 day mortality. Conclusions: Contemporary perioperative mortality and major complication rates for RCC patients with upper level thrombus are 10 and 34%, respectively. ECOG PS >1 and low serum albumin are associated with an increased risk of perioperative mortality, and should be considered when selecting patients for neoadjuvant systemic therapy trials.

Revision Tka

AbstractTotal knee arthroplasty (TKA) is a common and effective treatment of knee osteoarthritis. As the amount of TKAs performed increases, so does the number of TKA failures and subsequent revisions. Diabetes mellitus (DM) has been shown to increase complications following orthopaedic procedures. For these reasons, it is important to understand the association between severity of DM and the risk of postoperative adverse events following revision TKA. A retrospective cohort study was conducted using the American College of Surgeons' National Surgical Quality Improvement Program database. Patients who underwent revision TKAs between 2007 and 2016 were identified and recorded as having noninsulin-dependent DM (NIDDM), insulin-dependent DM (IDDM), or no DM. Univariate and multivariate analysis were used to evaluate the incidence of multiple adverse events within 30 days after revision TKA. A total of 13,246 patients who underwent revision TKA were selected (without DM = 10,381 [78.4%]; NIDDM = 1,890 [14.3%]; IDDM = 975 [7.4%]). Patients with NIDDM were found to have an increased risk of developing renal insufficiency and urinary tract infection (UTI) compared with patients without DM, while patients with IDDM were found to have an increased risk of developing 10 of 20 adverse events compared with patients without DM. NIDDM is an independent risk factor for UTI and IDDM is an independent factor for development of three complications compared with no DM. Insulin dependency is an independent factor for septic shock, postoperative blood transfusion, and extended postoperative hospital stay. Relative to patients with NIDDM, those with IDDM have a greater likelihood of developing more adverse perioperative outcomes than patients without DM. Although complication rates remain relatively low, orthopaedic surgeons must consider the implications of diabetes and insulin dependence on patient selection, preoperative risk stratification, and postoperative outcomes.

Abstract Background The optimal timing to perform a total knee arthroplasty (TKA) after knee arthroscopy (KA) was controversial in the literature. We aimed to 1) explore the effect of prior KA on the subsequent TKA; 2) identify who were not suitable for TKA in patients with prior KA, and 3) determine the timing of TKA following prior KA. Methods We retrospectively reviewed 87 TKAs with prior KA and 174 controls using propensity score matching in our institution. The minimum follow-up was 2 years. Postoperative clinical outcomes were compared between groups. Kaplan-Meier curves were created with reoperation as an endpoint. Multivariate Cox proportional hazards regressions were performed to identify risk factors of severe complications in the KA group. The two-piecewise linear regression analysis was performed to examine the optimal timing of TKA following prior KA. Results The all-cause reoperation, revision, and complication rates of the KA group were significantly higher than those of the control group (p < 0.05). The survivorship of the KA group and control group was 92.0 and 99.4% at the 2-year follow-up (p = 0.002), respectively. Male (Hazards ratio [HR] = 3.2) and prior KA for anterior cruciate ligament (ACL) injury (HR = 4.4) were associated with postoperative complications in the KA group. There was a non-linear relationship between time from prior KA to TKA and postoperative complications with the turning point at 9.4 months. Conclusion Prior KA is associated with worse outcomes following subsequent TKA, especially male patients and those with prior KA for ACL injury. There is an increased risk of postoperative complications when TKA is performed within nine months of KA. Surgeons should keep these findings in mind when treating patients who are scheduled to undergo TKA with prior KA.

The Impact

Study Design: Retrospective large database study. Objective: To determine the impact of cirrhosis on perioperative outcomes and resource utilization in elective spinal fusion surgery. Methods: Elective spinal fusion hospitalizations in patients with and without cirrhosis were identified using ICD-9-CM codes between the years of 2009 and 2011 using the Nationwide Inpatient Sample database. Main outcome measures were in-hospital neurologic, respiratory, cardiac, gastrointestinal, renal and urinary, pulmonary embolism, wound-related complications, and mortality. Length of stay and inpatient costs were also collected. Multivariable logistic regressions were conducted to compare the in-hospital outcomes of patients with and without cirrhosis undergoing spinal fusion. Results: A total of 1 214 694 patients underwent elective spinal fusions from 2009 to 2011. Oh these, 6739 were cirrhotic. Cirrhosis was a significant independent predictor for respiratory (odds ratio [OR] = 1.43, confidence interval [CI] 1.29-1.58; P < .001), gastrointestinal (OR = 1.72, CI 1.48-2.00; P < .001), urinary and renal (OR = 1.90, CI 1.70-2.12; P < 0.001), wound (OR = 1.36, CI 1.17-1.58; P < 0.001), and overall inpatient postoperative complications (OR = 1.43, CI 1.33-1.53; P < .001). Cirrhosis was also independently associated with significantly greater inpatient mortality (OR = 2.32, CI 1.72-3.14; P < .001). Cirrhotic patients also had significantly longer lengths of stay (5.35 vs 3.35 days; P < .001) and inpatient costs ($36 738 vs $29 068; P < .001). Conclusions: Cirrhosis is associated with increased risk of perioperative complications, mortality and greater resource utilization. Cirrhotic patients undergoing spinal fusion surgeries should be counseled on these increased risks. Current strategies for perioperative management of cirrhotic patients undergoing spinal fusion surgery need improvement.

AbstractVascular access site complications can follow diagnostic coronary and peripheral angiography. We compared the complication rates of the Catalyst vascular closure device, with the complication rates after manual compression in patients undergoing diagnostic angiographic procedures via femoral access. We studied 1,470 predominantly male patients undergoing diagnostic coronary and peripheral angiography. Catalyst closure devices were used in 436 (29.7%) patients and manual compression was used in 1,034 (70.3%) patients. The former were allowed to ambulate after 2 hours, while the latter were allowed to ambulate after 6 hours. Major complications occurred in 4 (0.9%) patients who had a Catalyst device and in 14 (1.4%) patients who had manual compression (odds ratio [OR]: 0.67, 95% confidence interval [CI]: 0.22–2.1, p = 0.49). Any complications occurred in 51 (11.7%) patients who had a Catalyst closure device and in 64 (6.2%) patients who had manual compression (OR: 2, CI: 1.4–3, p < 0.01). After adjustment for other variables and for a propensity score reflecting the probability to receive the closure device, the association of major complications with the use of the closure device remained not significant (OR: 0.54, 95% CI: 0.17–1.7, p = 0.29), while the association of any complications with the use of the Catalyst device remained significant (OR: 1.9, 95% CI: 1.3–2.9, p < 0.01). The Catalyst device was not associated with an increased risk of major groin complications but was associated with an increased risk of any complications compared with manual compression. Patients receiving the closure device ambulated sooner.

184 Background: Patient age is often a significant factor in preoperative selection for major abdominal surgery. Its association with postoperative outcomes in patients undergoing cytoreductive surgery(CRS) and hyperthermic intraperitoneal chemotherapy(HIPEC) remains ill-defined. Methods: The US HIPEC Collaborative database(2000-2017) was reviewed for patients who underwent a CCR0/1 CRS/HIPEC. Age was categorized into < 65 or >65yrs. Primary outcomes were postoperative major complications, readmission, 30-day mortality, and non-home discharge(NHD). Analysis was stratified by disease histology: non-invasive(appendiceal LAMN/HAMN), and invasive(appendiceal/colorectal adenocarcinoma). Results: Of 1090pts identified, 22% were >65yrs(n = 240), 59% were female(n = 646), 25% had non-invasive(n = 276) and 51% had invasive(n = 555) histology. Median PCI was 13(IQR7-20). Patients >65yrs had a higher rate of major complications(37vs26%, p = 0.02), readmission(28vs22%,p = 0.05), 30-day mortality(3vs1%,p = 0.02), and NHD(12vs5%,p < 0.01) compared to those < 65yrs. On multivariable analysis accounting for extent of disease as measured by PCI, for non-invasive histology, age >65yrs was an independent predictor for NHD(OR:2.54,95%CI:1.08-5.99,p = 0.03), but not major complications. For invasive histology, even when accounting for PCI, age >65yrs was an independent predictor for both NHD(OR:2.54,95%CI:1.08-5.98,p = 0.03) and major complications(OR:2.04,95%CI:1.16-3.59,p = 0.05). Age was not associated with hospital readmission or 30-day mortality for any histology. Conclusions: Regardless of histology, patients >65yrs are nearly at three-fold increased risk for non-home discharge after CRS/HIPEC. For invasive histology, age >65yrs is also associated with increased major complication rates, but the procedure seems to be better tolerated when performed for indolent biology. These data inform preoperative counseling and risk stratification. Early planning for discharge disposition in this high-risk population can potentially translate to cost savings.

Abstract Background: Total hip and total knee arthroplasty (THA/TKA) are increasing in incidence annually. While these procedures are effective in improving pain and function, there is a risk of complications. Methods: Using data from an arthroplasty registry, we described complication rates including reasons for reoperation and readmission from the acute period to six months following THA and TKA in an Australian context. Data collection at 6 months was conducted via telephone interview, and included patient-reported complications such as joint stiffness, swelling and paraesthesia. We used logistic regression to identify risk factors for complications. Results: In the 8,444 procedures included for analysis, major complications were reported by 9.5% and 14.4% of THA and TKA patients, respectively, whilst minor complications were reported by 34.0% and 46.6% of THA and TKA patients, respectively. Overall complications rates were 39.7% and 53.6% for THA and TKA patients, respectively. In THA patients, factors associated with increased risk for complications included increased BMI, previous THA and bilateral surgery, whereas in TKA patient factors were heart disease, neurological disease, and pre-operative back pain and arthritis in a separate joint. Female gender and previous TKA were identified as protective factors for minor complications in TKA patients.Conclusion: We found moderate rates of major and high rates of minor postoperative complications following THA and TKA in Australia and have identified several patient factors associated with these complications. Efforts should be focused on identifying patients with higher risk and optimising pre- and post-operative care to reduce the rates of these complications.

We analyzed gender-based differences in preoperative factors, procedural characteristics, and 30-day outcomes after lower extremity bypass (LEB). LEB procedures were identified from the American College of Surgeons National Surgical Quality Improvement Program Participant User File. Groupwise comparisons of preoperative and procedural variables were made using chi square, t tests, and nonparametric methods; gender influences on mortality, systemic, and surgical site complications were evaluated using logistic regression. Women (4,107 of 11,011 [37.3%]) were older and had greater prevalence of hypertension, diabetes, chronic obstructive pulmonary disease, rest pain, dialysis, previous stroke, open/infected wound, and dependent functional status ( P < 0.01 for all comparisons). Women more commonly underwent emergent and extra-anatomic procedures but had lower rates of venous conduit or tibial level outflow use. Univariable associations between female gender and risk of 30-day mortality, systemic, and surgical site complications were identified; only the association with surgical site complications remained significant in multivariable modeling (OR, 1.8; 95% CI, 1.6 to 2.1; P < 0.0001). Gender-based differences in demographic, comorbidity, and procedural factors may contribute to disparities in perioperative outcomes associated with LEB. Female gender may be associated with increased risk for surgical site complications, but 30-day mortality and systemic complication rates in women may reflect effects of confounding factors rather than gender-specific influence.

OBJECTIVEDeep brain stimulation (DBS) is an elective procedure that can dramatically enhance quality of life. Because DBS is not considered lifesaving, it is important that providers produce consistently good outcomes, and one factor they usually consider is patient age. While older age may be a relative contraindication for some elective surgeries, the progressive nature of movement disorders treated with DBS may suggest that older patients stand to benefit substantially from surgery. To better understand the risks of treating patients of advanced age with DBS, this study compares perioperative complication rates in patients ≥ 75 to those < 75 years old.METHODSPatients undergoing DBS surgery for various indications by a single surgeon (May 2013–July 2019) were stratified into elderly (age ≥ 75 years) and younger (age < 75 years) cohorts. The risks of common perioperative complications and various outcome measures were compared between the two age groups using risk ratios (RRs) and 95% confidence intervals (CIs).RESULTSA total of 861 patients were available for analysis: 179 (21%) were ≥ 75 years old and 682 (79%) were < 75 years old (p < 0.001). Patients ≥ 75 years old, compared with those < 75 years old, did not have significantly different RRs (95% CIs) of seizure (RR 0.4, 95% CI 0.1–3.3), cerebrovascular accident (RR 1.9, 95% CI 0.4–10.3), readmission within 90 days of discharge (RR 1.22, 95% CI 0.8–1.8), explantation due to infection (RR 2.5, 95% CI 0.4–15.1), or surgical revision (for lead, RR 2.5, 95% CI 0.4–15.1; for internal pulse generator, RR 3.8, 95% CI 0.2–61.7). Although the risk of postoperative intracranial bleeding was higher in the elderly group (6.1%) than in the younger group (3.1%), this difference was not statistically significant (p = 0.06). However, patients ≥ 75 years old did have significantly increased risk of altered mental status (RR 2.5, 95% CI 1.6–4.0), experiencing more than a 1-night stay (RR 1.7, 95% CI 1.4–2.0), and urinary retention (RR 2.3, 95% CI 1.2–4.2; p = 0.009).CONCLUSIONSAlthough elderly patients had higher risks of certain outcome measures than younger patients, this study showed that elderly patients undergoing DBS for movement disorders did not have an increased risk of more serious complications, such as intracranial hemorrhage, infection, or readmission. Advanced age alone should not be considered a contraindication for DBS.
