- Abstract
Obstructive sleep apnea (OSA) is highly prevalent in patients undergoing total joint arthroplasty (TJA) and is a major risk factor for postoperative cardiovascular complications and death. Recognizing this, the American Society of Anesthesiologists urges clinicians to implement special considerations in the perioperative care of OSA patients. However, as the volume of patients presenting for TJA increases, resources to implement these recommendations are limited. This necessitates mechanisms to efficiently risk stratify patients having OSA who may be susceptible to post-TJA cardiovascular complications. We explore the role of perioperative measurement of cardiac troponins (cTns) and brain natriuretic peptides (BNPs) in helping determine which OSA patients are at increased risk for post-TJA cardiovascular-related morbidity.

- Abstract
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. [ABSTRACT FROM AUTHOR]

Background: While increased surgical-provider volume has been associated with improved outcomes, research regarding volume-outcome relationships within high-volume institutions and the role of anaesthesiologists is limited. Further, the effect of anaesthesia-care-team composition remains understudied. This analysis aimed to identify the impact of anaesthesiologist and surgeon volume on adverse events after total joint arthroplasties.Methods: We retrospectively identified 40 437 patients who underwent total joint arthroplasties at a high-volume institution from 2005 to 2014. The main effects of interest were anaesthesiologist and surgeon volume and experience along with anaesthesia-care-team composition. Multivariable logistic regression models were used to evaluate three outcomes: any complication, cardiopulmonary complication, and length of stay (>5 days). Odds ratios (ORs) and 99.75% confidence intervals (CIs) were reported.Results: Across all three models, anaesthesiologist volume and experience, and anaesthesia-care-team composition were not significant predictors. Surgeon annual case volume >50 was associated with significantly reduced odds of any complication (annual case volume: 50-149; OR: 0.80; CI: 0.66-0.98) and prolonged length of stay (OR: 0.69; CI: 0.60-0.80). Surgeon experience >20 yr was associated with significantly reduced odds of prolonged length of stay (OR: 0.85; CI: 0.75-0.95).Conclusions: Anaesthesiologist volume and experience, and anaesthesia-care-team composition did not impact the odds of an adverse outcome, although a higher surgeon volume was associated with decreased odds of complications and prolonged length of stay. Further study is necessary to determine if these findings can be extrapolated to less specialised, lower volume surgical settings. [ABSTRACT FROM AUTHOR]- Published

Background: Evidence-based international expert consensus regarding anaesthetic practice in hip/knee arthroplasty surgery is needed for improved healthcare outcomes.Methods: The International Consensus on Anaesthesia-Related Outcomes after Surgery group (ICAROS) systematic review, including randomised controlled and observational studies comparing neuraxial to general anaesthesia regarding major complications, including mortality, cardiac, pulmonary, gastrointestinal, renal, genitourinary, thromboembolic, neurological, infectious, and bleeding complications. Medline, PubMed, Embase, and Cochrane Library including Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, NHS Economic Evaluation Database, from 1946 to May 17, 2018 were queried. Meta-analysis and Grading of Recommendations Assessment, Development and Evaluation approach was utilised to assess evidence quality and to develop recommendations.Results: The analysis of 94 studies revealed that neuraxial anaesthesia was associated with lower odds or no difference in virtually all reported complications, except for urinary retention. Excerpt of complications for neuraxial vs general anaesthesia in hip/knee arthroplasty, respectively: mortality odds ratio (OR): 0.67, 95% confidence interval (CI): 0.57-0.80/OR: 0.83, 95% CI: 0.60-1.15; pulmonary OR: 0.65, 95% CI: 0.52-0.80/OR: 0.69, 95% CI: 0.58-0.81; acute renal failure OR: 0.69, 95% CI: 0.59-0.81/OR: 0.73, 95% CI: 0.65-0.82; deep venous thrombosis OR: 0.52, 95% CI: 0.42-0.65/OR: 0.77, 95% CI: 0.64-0.93; infections OR: 0.73, 95% CI: 0.67-0.79/OR: 0.80, 95% CI: 0.76-0.85; and blood transfusion OR: 0.85, 95% CI: 0.82-0.89/OR: 0.84, 95% CI: 0.82-0.87.Conclusions: Recommendation: primary neuraxial anaesthesia is preferred for knee arthroplasty, given several positive postoperative outcome benefits; evidence level: low, weak recommendation.Recommendation: neuraxial anaesthesia is recommended for hip arthroplasty given associated outcome benefits; evidence level: moderate-low, strong recommendation. Based on current evidence, the consensus group recommends neuraxial over general anaesthesia for hip/knee arthroplasty.Trial Registry Number: PROSPERO CRD42018099935.

Same-day Bilateral Total Knee Arthroplasty (BTKA) safety is still controversial. The aim of this study was to examine the association of blood transfusion type (pure autologous, pure allogeneic, and combined) with complication and prolonged length of stay (PLOS) following same-day BTKA. 649 consecutive patients were retrospectively identified over a two-year period. Pure allogeneic transfusions were associated with increased odds of minor complication when compared to patients who had pure autologous transfusions. No association was found between blood transfusion type and major complication or PLOS. Our results suggest that blood transfusion type may be influential in minor complication after BTKA.

- Abstract
This pilot study explores sleep disruption after total knee arthroplasty and the impact of melatonin on sleep and postoperative pain. Sleep time was decreased on the last preoperative night and first two postoperative nights. Sleep efficiency was decreased on all three postoperative nights. Compared to placebo, melatonin increased sleep efficiency by 4.4% (mean; 95% CI -1.6, 10.4; P=0.150) and sleep time by 29 min (mean; 95% CI -2.0, 60.4; P=0.067). Melatonin appeared to have no effect on subjective sleep quality or daytime sleepiness, pain at rest or pain with standardized activity. In conclusion, sleep quality is impaired after total knee arthroplasty and exogenous melatonin does not appear to improve postoperative sleep or pain to a significant degree. [ABSTRACT FROM AUTHOR]

Background: Scarce data exist on differential opioid prescribing between men and women in the pre-, peri-, and postoperative phases of care among patients undergoing total hip/knee arthroplasty (THA/TKA).Methods: In this retrospective population-based study, Truven Health MarketScan claims data were used to establish differences between men and women in (1) opioid prescribing in the year before THA/TKA surgery, (2) the amount of opioids prescribed at discharge, and (3) chronic opioid prescribing (3-12 months after surgery). Multivariable regression models measured odds ratios (OR) with 95% confidence intervals (95% CI).Results: Among 29 038 THAs (42% men) and 48 523 TKAs (52% men) men (compared with women) were less likely to receive an opioid prescription in the year before surgery (54% vs 60%, and 54% vs 60% for THA and TKA, respectively); P<0.001. However, in multivariable analyses male sex was associated with higher total opioid dosages prescribed at discharge after THA (OR=1.04; 95% CI 1.03, 1.06) and TKA (OR=1.05; 95% CI 1.04, 1.06); both P<0.001. Chronic opioid prescribing was found in 10% of the cohort (THA: n=2333; TKA: n=5365). Here, men demonstrated lower odds of persistent opioid prescribing specifically after THA (OR=0.90; 95% CI 0.82, 0.99) but not TKA (OR=0.96; 95% CI 0.90, 1.02); P=0.026 and P=0.207, respectively.Conclusions: We found sex-based differences in opioid prescribing across all phases of care for THA/TKA. The results highlight temporal opportunities for targeted interventions to improve outcomes after total joint arthroplasty, particularly for women, and to decrease chronic opioid prescribing.

To analyze the use of neuraxial techniques in total hip or knee arthroplasty patients who previously underwent lumbar spine surgeries. Retrospective analysis of a national database. U.S. hospitals. Patients undergoing a total hip or knee arthroplasty, stratified by those with a previous lumbar fusion or decompression procedure. Our primary outcome was the use of neuraxial anesthesia; secondary outcomes included combined complications, cardio-pulmonary complications, and prolonged length of stay. Patients with and without a history of a lumbar procedure were compared using mixed-effects regression. Among 758,857 THAs 8961 had a history of lumbar fusion and 8599 of decompression. Among 1,387,335 TKAs 15,827 had a history of lumbar fusion and 13,652 of decompression. History of a lumbar fusion was associated with lower odds of neuraxial anesthesia use in THA (OR: 0.74 CI: 0.70–0.79, p ≤0.0001) and TKA (OR: 0.80 CI: 0.77–0.84, p ≤0.0001). Previous lumbar fusion -but not decompression- surgery is associated with lower neuraxial anesthesia in THA/TKA patients, despite its use being universally associated with decreased length of stay. More research is needed to address the importance of neuraxial techniques in patients with prior spine surgery. • Lumbar procedures are common in the U.S. and are expected to increase in practice. • We analyzed more than 2.1 million patients undergoing total joint arthroplasty. • Only 15.6% of patients with previous lumbar fusion received neuraxial anesthesia. • History of a lumbar fusion was associated with lower odds of neuraxial anesthesia use.

Given the basic need for opioids in the perioperative setting, we investigated associations between opioid prescription levels and postoperative outcomes using population-based data of orthopedic surgery patients. We hypothesized that increased opioid amounts would be associated with higher risk for postoperative complications. Data were extracted from the national Premier Perspective database (2006-2013); N51,035,578 lower joint arthroplasties and N5220,953 spine fusions. Multilevel multivariable logistic regression models measured associations between opioid dose prescription and postoperative outcomes, studied by quartile of dispensed opioid dose. Compared to the lowest quartile of opioid dosing, high opioid prescription was associated with significantly increased odds for deep venous thrombosis and postoperative infections by approx. 50%, while odds were increased by 23% for urinary and more than 15% for gastrointestinal and respiratory complications (P < 0.001 respectively). Furthermore, higher opioid prescription was associated with a significant increase in length of stay (LOS) and cost by 12% and 6%, P < 0.001 respectively. Cerebrovascular complications risk was decreased by 25% with higher opioid dose (P = 0.004), while odds for myocardial infarction remained unaltered. In spine cases, opioid prescription was generally higher, with stronger effects observed for increase in LOS and cost as well as gastrointestinal and urinary complications. Other outcomes were less pronounced, possibly because of smaller sample size. Overall, higher opioid prescription was associated with an increase in most postoperative complications with the strongest effect observed in thromboembolic, infectious and gastrointestinal complications, cost, and LOS. Increase in complication risk occurred stepwise, suggesting a dose-response gradient. [ABSTRACT FROM AUTHOR]
