Causal effects of endometriosis on SLE, RA and SS risk: evidence from meta-analysis and Mendelian randomization

BACKGROUND

Endometriosis is an underdiagnosed disorder that affects an estimated 6-10% of women of reproductive age. Endometriosis has been reported in epidemiological studies to be associated with autoimmune diseases. However, the relationship remains controversial.

METHODS

A meta-analysis of observational studies was undertaken to evaluate the risk of autoimmune diseases in patients with endometriosis. The relevant studies were retrieved via the databases Medline, Embase and Web of Science until July 20, 2023. Mendelian randomization (MR) was subsequently utilized to scrutinize the causal influence of genetic predisposition toward endometriosis on three autoimmune diseases.

RESULTS

The meta-analysis findings revealed a relationship between endometriosis and the onset of SLE (cohort studies: RR = 1.77, 95% confidence interval (CI): 1.47-2.13, I2 = 0%; Case-control and cross-sectional studies: OR = 5.23, 95% CI: 0.74-36.98, I2 = 98%), RA (cohort studies: RR = 2.18, 95% CI: 1.85-2.55, I2 = 92%; Case-control and cross-sectional studies: OR = 1.40, 95% CI: 1.19-1.64, I2 = 0%) and SS (cohort studies: RR = 1.49, 95% CI: 1.34-1.66, I2 = 0%). Similarly, in our MR study, the results of the inverse-variance-weighted (IVW) model suggested that genetic predisposition to endometriosis was causally associated with an increased risk for SLE (OR = 1.915, 95% CI: 1.204-3.045, p = 0.006) and RA (OR = 1.005, 95% CI: 1.001-1.009, p = 0.014).

CONCLUSIONS

Both our meta-analysis and MR study indicate that endometriosis increases the risk of autoimmune diseases. These findings not only broaden our understanding of the genetic mechanisms underlying the comorbidity of endometriosis and autoimmune diseases, but also offer a new strategy for autoimmune disease prevention.

Synthesis of 'joint class' curricula at high volume joint replacement centres and a preliminary model for development and evaluation

RATIONALE

Preoperative patient education through 'joint class' has potential to improve quality of care for total joint replacement (TJR). However, no formal guidance exists regarding curriculum content, potentially resulting in inter-institutional variation.

OBJECTIVE

We aimed to (a) synthesize curriculum components of 'joint classes' across high-volume institutions and (b) develop a preliminary theory of change model for development and evaluation guided by the existing curricula and related literature.

METHODS

We reviewed 'joint class' curricula from the websites of the 10 highest-volume TJR centres (by average annual 2017-2019 volume) that publicly disclosed this information. Two reviewers qualitatively compared available content and noted common categories, which were synthesized into key domains across institutions. We then reviewed the PubMed database for literature on pre-TJR patient education and education needs in the past 10 years. Drawing on our curriculum synthesis and related literature, we proposed a theory of change model: hypothesized mechanisms through which 'joint class' confers benefits to patients and health systems.

RESULTS

We identified 30 categories in our review of existing class content, which we synthesized into seven key domains: (I) Practical Elements, (II) Logistics, (III) Medical Information, (IV) Modifiable Risk Factors, (V) Expected Outcomes, (VI) Patient Role in Recovery and (VII) Enhanced Education. Variation across institutions was noted. Our preliminary model based on the curriculum synthesis and related literature on the impact of 'joint class' includes three levels: (1) Practical Elements ('joint class' accessibility and information quality), (2) Class Goals (increased health literacy, increased adherence, risk mitigation, realistic expectations, and reduced anxiety) and (3) Target Outcomes (improved clinical outcomes, positive patient experience and increased patient satisfaction).

CONCLUSION

Our synthesis identified core common topics included in pre-TJR education but also highlighted variation across institutions, supporting opportunities for standardization. Clinicians and researchers can use our preliminary model to systematically develop and evaluate 'joint classes,' with the goal of establishing a standard of care for TJR preoperative education.

Lipid profiles in patients with juvenile idiopathic arthritis: a systematic literature review and meta-analysis

OBJECTIVE

The purpose of this study was to comprehensively evaluate the lipid profiles in patients with juvenile idiopathic arthritis (JIA).

METHODS

The literature and relevant reviews were searched for published clinical studies on the relationship between JIA and blood lipid levels. The Newcastle-Ottawa scale (NOS) was applied to evaluate the risk and methodological value of the included case‒control and cohort studies. Standardized mean differences (SMDs) and 95% confidence intervals were derived for all variables with adequate unprocessed data. This meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines.

RESULTS

In total, 16 studies were incorporated through screening. The analysis findings revealed that the levels of very low-density lipoprotein cholesterol [SMD=-0.411, 95% CI (-0.774~-0.048), P = 0.026], high-density lipoprotein cholesterol [SMD=-0.528, 95% CI (-0.976~-0.079), P = 0.021], and apolipoprotein A1 [SMD=-1.050, 95% CI (-1.452~-0.647), P = 0.000] in JIA patients were statistically lower than those observed in healthy controls. The level of low-density lipoprotein cholesterol [SMD = 0.202, 95% CI (0.003 ~ 0.400), P = 0.046] was significantly higher in JIA patients than in healthy controls. In JIA patients, body mass index [SMD=-0.189, 95% CI (-0.690 ~ 0.311), P = 0.459], high-density lipoprotein [SMD =-1.235, 95% CI (-2.845 ~ 0.374), P = 0.133), low-density lipoprotein [SMD = 0.616, 95% CI (-0.813 ~ 2.046), P = 0.398), triglycerides (SMD = 0.278, 95% CI (-0.182 ~ 0.738), P = 0.236], total cholesterol [SMD=-0.073, 95% CI (-0.438 ~ 0.293), P = 0.696] and apolipoprotein B levels [SMD = 0.226, 95% CI (-0.133 ~ 0.585), P = 0.217] were not significantly different from those in healthy controls.

CONCLUSIONS

The outcomes of this meta-analysis suggest that dyslipidemia is common in JIA patients compared to healthy controls. Patients with JIA have a significantly increased risk of atherosclerosis and cardiovascular disease later in life.

Effect of Adding Perineural Methylprednisolone to Peripheral Nerve Blocks Combined With Intravenous Dexamethasone for Prolonged Postdischarge Analgesia After Fast-track Total Knee Arthroplasty: A Randomized Controlled Trial

OBJECTIVES

Patients undergoing total knee arthroplasty (TKA) may experience moderate-to-severe subacute pain after hospital discharge that may be undermanaged. We aimed to evaluate the effect of methylprednisolone added to ultrasound-guided peripheral nerve blocks (PNBs) combined with multimodal analgesia including intravenous dexamethasone for prolonged analgesia after early discharge.

MATERIALS AND METHODS

We randomized 80 patients who underwent fast-track TKA into 2 groups. All patients received a periarticular injection, PNBs, and multiple doses of intravenous dexamethasone. The methylprednisolone group received 140 mg methylprednisolone in PNBs, while the nonmethylprednisolone group did not. The primary outcome was the incidence of moderate-to-severe pain (Numerical Rating Scale ≥4) during the first 12 postdischarge days. The secondary outcomes included pain scores until 3 postoperative months, incidence of rebound pain, functional performances, patient satisfaction, and adverse events.

RESULTS

No significant between-group differences were noted in the incidence of moderate-to-severe pain during the first 12 postdischarge days (nonmethylprednisolone vs. methylprednisolone groups: 70% vs. 69.2%, P=0.941). However, this incidence was significantly higher in the methylprednisolone group between 2 weeks and 1 month (P=0.015) and between 1 and 3 months (P=0.004) postoperatively. No between-group differences in the Numerical Rating Scale scores at the postdischarge time points, incidence of rebound pain, and functional performance results were noted.

DISCUSSION

Adding perineural methylprednisolone to ultrasound-guided PNBs for multimodal analgesia with intravenous dexamethasone did not prolong analgesia and improved the functional ability after fast-track TKA within 12 postdischarge days. However, the incidence moderate-to-severe pain may increase between the 2-week and 3-month follow-up.

Peripheral nerve-blocks and associations with length of stay and readmissions in fast-track total hip and knee arthroplasty

BACKGROUND

Peripheral nerve blocks (PNB) have recently been recommended in total hip (THA) and knee (TKA) arthroplasty as they may reduce pain, morphine consumption, length of stay (LOS) and complications. However, whether PNBs are associated with early discharge within an enhanced recovery protocol including multimodal analgesia is uncertain.

METHODS

An observational multicenter study from January to August 2017 in six Danish Arthroplasty Centers with established fast-track protocols. Prospective recording of preoperative characteristics and information on PNB, LOS and readmissions through the Danish National Patient Registry and medical records. Multiple logistic regression was used to investigate associations between PNB and a LOS >1 day, LOS >4 days, and 30-days readmissions. We also reported on mobilization, pain, opioid and fall-related complications leading to LOS >4 days or readmissions.

RESULTS

A total of 2027 (58.6%) THA and 1432 (41.4%) TKAs with a median LOS of 1 day (IQR 1-2) and 5.3% (CI:4.6-6.1) 30-days readmission rate were identified. PNB was used in 40.7% (CI:38.2-43.3) of TKA and 2.7% (CI:2.0-3.5) of THA, but with considerable interdepartmental variation (0.0-89.0% for TKA). There was no association between PNB and LOS >1 day (OR:1.19 CI:0.82-1.72; p = .354), LOS >4 days (OR:1.4 CI:0.68-2.89; p = .359) or 30-days readmissions (OR:1.02 CI:0.63-1.65; p = .935) in TKA. Logistic regression in THA was not possible due to limited use of PNB. In TKA there were 12 (2.1% CI:1.2-3.6) with and 1 (0.1% CI:0.02-0.7) without a PNB, who had mobilization, pain or opioid-related complications, and 5 (0.9% CI:0.4-2.0) versus 4 (0.5% CI:0.2-1.2) who fell. Correspondingly, 2 (3.7% CI:1.0-12.6) and 11 (0.6% CI:0.3-1.0) of THA patients had these complications, while 0 (0.0% CI:0.0-6.6) and 17 (0.8% CI:0.5-1.3) fell.

CONCLUSION

Routine use of peripheral nerve blocks was not associated with early discharge or 30-days readmissions in fast-track THA and TKA. Future studies should focus on benefits of PNB in high-risk patients.

Comparison Between Periarticular Analgesia Versus Intraarticular Injection for Effectiveness and Safety After Total Knee Arthroplasty

PURPOSE

In most studies, local infiltration analgesia (LIA) can provide better analgesic effect in the early postoperative period, but the optimal technique is unknown. Our study was designed to evaluated the early clinical efficacy and safety of periarticular analgesia versus intraarticular injection in Total knee arthroplasty (TKA).

DESIGN

A prospective study was conducted on 100 patients admitted for TKA. Subjects were divided into two groups: 50 in group A, 50 in Group B.

METHODS

Patients in group A received periarticular analgesia with ropivacaine 300 mg and morphine 5 mg (the drugs were diluted with saline to 50 ml) in the periosteal borders, posterior capsule and extensor apparatus and subcutaneous tissues during surgery. After stitching of joint capsule, tranexamic acid (TXA) 2 g (20 ml) was injected into the articular cavity. Group B patients had all of the 70 mL mixture (ropivacaine 300 mg, morphine 5 mg and TXA 2 g) injected intraarticularly after stitching of the joint capsule. We assessed postoperative length of stay (LOS), knee functional outcome, pain, and complications after surgery.

FINDINGS

There was no statistical difference in visual analog scale (VAS) scores for knee pain between the two groups on postoperative day (POD)1, 3, or 30 (P > .05). Mean postoperative LOS was 7.40 ± 1.98 days in Group A, compared to 8.02 ± 2.09 days in Group B (P > .05). No significant differences between groups were seen in the mean swelling ratio (P > .05), and no significant differences were found in the Hospital for Special Surgery (HSS) knee score and range of motion (ROM) at 30 days follow-up (P > .05). There was also no statistical difference in the incidence of complications (such as superficial wound infection, deep vein thrombosis (DVT) and nausea and vomiting) between the Group A and the Group B.

CONCLUSIONS

In conclusion, it seems that intraarticular injection had a similar analgesic effect compared with periarticular injection when adopting a multi-modal analgesia regimen. Our results suggest that there is no obvious advantage with the use of periarticular injections compared to intraarticular injection. The authors believe that intraarticular injection may be a better technique compared with periarticular injections in the absence of a drainage tube because intraarticular injection can reduce the number of surgical steps and have similar postoperative outcomes.

Pain management after total knee arthroplasty: PROcedure SPEcific Postoperative Pain ManagemenT recommendations

BACKGROUND

The PROSPECT (PROcedure SPEcific Postoperative Pain ManagemenT) Working Group is a global collaboration of surgeons and anaesthesiologists formulating procedure-specific recommendations for pain management after common operations. Total knee arthroplasty (TKA) is associated with significant postoperative pain that is difficult to treat. Nevertheless, pain control is essential for rehabilitation and to enhance recovery.

OBJECTIVE

To evaluate the available literature and develop recommendations for optimal pain management after unilateral primary TKA.

DESIGN

A narrative review based on published systematic reviews, using modified PROSPECT methodology.

DATA SOURCES

A literature search was performed in EMBASE, MEDLINE, PubMed and Cochrane Databases, between January 2014 and December 2020, for systematic reviews and meta-analyses evaluating analgesic interventions for pain management in patients undergoing TKA.

ELIGIBILITY CRITERIA

Each randomised controlled trial (RCT) included in the selected systematic reviews was critically evaluated and included only if met the PROSPECT requirements. Included studies were evaluated for clinically relevant differences in pain scores, use of nonopioid analgesics, such as paracetamol and nonsteroidal anti-inflammatory drugs and current clinical relevance.

RESULTS

A total of 151 systematic reviews were analysed, 106 RCTs met PROSPECT criteria. Paracetamol and nonsteroidal anti-inflammatory or cyclo-oxygenase-2-specific inhibitors are recommended. This should be combined with a single shot adductor canal block and peri-articular local infiltration analgesia together with a single intra-operative dose of intravenous dexamethasone. Intrathecal morphine (100 μg) may be considered in hospitalised patients only in rare situations when both adductor canal block and local infiltration analgesia are not possible. Opioids should be reserved as rescue analgesics in the postoperative period. Analgesic interventions that could not be recommended were also identified.

CONCLUSION

The present review identified an optimal analgesic regimen for unilateral primary TKA. Future studies to evaluate enhanced recovery programs and specific challenging patient groups are needed.

Critical appraisal of randomised trials assessing regional analgesic interventions for knee arthroplasty: implications for postoperative pain guidelines development

Guidelines are increasingly being used for clinical decision-making. Such guidelines are usually based on meta-analyses, which are generally derived from RCTs. However, their interpretations are often hindered as they do not always consider current clinical relevance. Analyses of RCTs assessing analgesic efficacy of advanced regional analgesic techniques in knee arthroplasty show that the majority of trials do not include a package of basic analgesics such as paracetamol, NSAIDs or cyclooxygenase-2 specific inhibitors, dexamethasone, and local infiltration analgesia in the comparator group. Consequently, the current approach to analyse meta-analyses of pain interventions is not optimal, and may lead to inadequate or inappropriate conclusions and clinical guidance.

The Intraoperative Adherence to Multimodal Analgesia of Anesthesiologists: A Retrospective Study

Introduction

Multimodal analgesia (MMA) is a critical component of enhanced recovery after surgery (ERAS). However, little research revealed its intraoperative implementation by anesthesiologists, who are on the front line defending against surgical pain. Therefore, the objective of our study is to assess the adherence of anesthesiologists to MMA comprehensively.

Methods

A retrospective study was conducted involving patients undergoing lung resection, knee arthroplasty, and radical mastectomy from pre/post-implementation year of MMA (Jan 1, 2013, to Dec 31, 2013, vs. 2019). Intraoperative analgesia regimens (analgesic mode) and hourly rated morphine milligram equivalents (MME) were compared. In addition, patient characteristics associated with continued opioid use after surgery, surgical types, and position level of anesthesiologists (attending-junior; above attending-senior) were also analyzed.

Results

After MMA initiation, the rate of multimodal analgesic regimen (mode ≥ 2) was significantly increased (post- vs. pre-implementation, 31.57 vs. 21.50%, p < 0.05). However, MME did not show significant difference (post- vs. pre-implementation, 0.402 vs. 0.456, p > 0.05). Patient-level predictors of persistent opioid use after surgery were not related to increased analgesic mode. Lung resection [coefficient, − 0.538; 95% confidence interval (CI), − 0.695 to − 0.383, p < 0.001] and knee arthroplasty (coefficient, − 1.143; 95% CI, − 1.366 to − 0.925, p < 0.001) discouraged multiple analgesic mode, while senior anesthesiologists (coefficient, 0.674; 95% CI 0.548–0.800, p < 0.001) promoted it.

Conclusions

Although anesthesiologists used more analgesics after promoting MMA, the “opioid-sparing” principle was not followed properly. The analgesic mode was not instructed by patients’ characteristics appropriately. In addition, surgeries with cumbersome preparation/process impeded the use of multiple analgesic modes, while senior anesthesiologists preferred multiple analgesic modes.

Hip and Knee Arthroplasty

Variation in care is associated with variation in outcomes after total joint arthroplasty (TJA). Accordingly, much research into enhanced recovery efficacy for TJA has been devoted to linking standardization with better outcomes. This article focuses on recent advances suggesting that variation within a set of core protocol elements may be less important than providing the core elements within enhanced recovery pathways for TJA. Provided the core elements are associated with benefits for patients and health care system outcomes, variation in the details of their provision may contribute to a pathway's success. This article provides an updated review of the literature.

Postoperative Pain Management in Enhanced Recovery Pathways

Postoperative pain is a common but often inadequately treated condition. Enhanced recovery pathways (ERPs) are increasingly being utilized to standardize perioperative care and improve outcomes. ERPs employ multimodal postoperative pain management strategies that minimize opioid use and promote recovery. While traditional opioid medications continue to play an important role in the treatment of postoperative pain, ERPs also rely on a wide range of non-opioid pharmacologic therapies as well as regional anesthesia techniques to manage pain in the postoperative setting. The evidence for the use of these interventions continues to evolve rapidly given the increasing focus on enhanced postoperative recovery. This article reviews the current evidence and knowledge gaps pertaining to commonly utilized modalities for postoperative pain management in ERPs.

Advantages and issues of concern regarding approaches to peripheral nerve block for total hip arthroplasty

In older patients with comorbidities, hip fractures are both an important and debilitating condition. Since multimodal and multidisciplinary perioperative strategies can hasten functional recovery after surgery improving clinical outcomes, the choice of the most effective and safest pathway represents a great challenge. A key point of concern is the anesthetic approach and above all the choice of the locoregional anesthesia combined with general or neuraxial anesthesia.

Effect of Mobilization on the Day of Surgery After Total Hip Arthroplasty in Elderly, Obese, and Severely Diseased Patients

BACKGROUND

Mobilization on the day of surgery after total hip arthroplasty (THA) is widely used. However, elderly, obese and severely diseased patients are often excluded from early mobilization. Therefore, it was our aim to investigate the effect of mobilization on the day of surgery with focus on these patients.

METHODS

167 patients underwent THA via direct anterior approach. Exclusion criterion was the use of wound drainage. The patients were randomly allocated to two groups. Day 0 group was mobilized 4 hours after surgery, day 1 group the day after surgery. Primary outcome was the time to readiness for discharge (TRD). Secondary outcome was the occurrence of adverse events (vertigo, nausea, vomiting, severe pain) on the day of surgery. Group comparisons were calculated with respect to elderly (age ≥75 years), obese (BMI ≥30 kg/m²) and severely diseased patients (ASA≥3).

RESULTS

TRD was shorter in day 0 group (3.25 vs 3.99 days, P < .01). The rate of adverse events on the day of surgery was similar in both groups (0.28 vs 0.25, P = .73). TRD differences were higher within all subgroups (3.85vs4.81; 3.25vs4.39; 4.08vs5.11days) while the rate of immediate adverse events was reduced (0.15vs0.24; 0.25vs0.3; 0.25vs0.33). Within 90 days 3 patients of group 0 underwent revision surgery, none of group 1 (P = .12).

CONCLUSION

Mobilization on the day of surgery reduces the TRD without increasing the rate of immediate adverse events, regardless of age, BMI and ASA score. Future studies are needed to investigate if early mobility increases the 90-days complication rate.

Enhanced Recovery After Primary Total Hip and Knee Arthroplasty: A Systematic Review

BACKGROUND

Enhanced Recovery After Surgery (ERAS) has become increasingly implemented to reduce costs, to increase efficiency, and to optimize patient outcomes after a surgical procedure. This study aimed to systematically review the effect of ERAS after primary elective total hip arthroplasty (THA) or total knee arthroplasty (TKA) on hospital length of stay, total procedure-related morbidity, and readmission.

METHODS

A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and with guidance from the Cochrane Handbook for Systematic Reviews of Interventions. MEDLINE, Embase, and Cochrane databases were searched from inception (1946 for MEDLINE and 1974 for Embase; Cochrane is a composite of multiple databases and thus does not report a standard inception date) until January 15, 2020. Prospective nonrandomized cohort studies and randomized controlled trials comparing adult patients undergoing elective primary THA or TKA with ERAS or traditional protocols were included. Articles examining outpatient, nonelective, or revision surgical procedures were excluded. Two reviewers independently assessed the risk of bias and extracted data. The primary outcome was length of stay. The secondary outcomes included total procedure-related morbidity and readmission.

RESULTS

Of the 1,018 references identified (1,017 identified through an electronic search and 1 identified through a manual search), 9 individual studies met inclusion criteria. Data were reported from 7,789 participants, with 2,428 receiving ERAS and 5,361 receiving traditional care. Narrative synthesis was performed instead of meta-analysis, given the presence of moderate to high risk of bias, wide variation of ERAS interventions, and inconsistent methods for assessing and reporting outcomes among included studies. Adherence to ERAS protocols consistently reduced hospital length of stay. Few studies demonstrated reduced total procedure-related morbidity, and there was no significant effect on readmission rates.

CONCLUSIONS

ERAS likely reduced the length of stay after primary elective THA and TKA, with a more pronounced effect in selected healthier patient populations. We found minimal to no impact on perioperative morbidity or readmission. The quality of existing evidence was limited because of study heterogeneity and a significant risk of bias. Further high-quality research is needed to definitively assess the impact of ERAS on total joint arthroplasty.

Orthogeriatric co-management for the care of older subjects with hip fracture: recommendations from an Italian intersociety consensus

BACKGROUND

Health outcomes of older subjects with hip fracture (HF) may be negatively influenced by multiple comorbidities and frailty. An integrated multidisciplinary approach (i.e. the orthogeriatric model) is, therefore, highly recommended, but its implementation in clinical practice suffers from the lack of shared management protocols and poor awareness of the problem. The present consensus document has been implemented to address these issues.

AIM

To develop evidence-based recommendations for the orthogeriatric co-management of older subjects with HF.

METHODS

A 20-member Expert Task Force of geriatricians, orthopaedics, anaesthesiologists, physiatrists, physiotherapists and general practitioners was established to develop evidence-based recommendations for the pre-, peri-, intra- and postoperative care of older in-patients (≥ 65 years) with HF. A modified Delphi approach was used to achieve consensus, and the U.S. Preventive Services Task Force system was used to rate the strength of recommendations and the quality of evidence.

RESULTS

A total of 120 recommendations were proposed, covering 32 clinical topics and concerning preoperative evaluation (11 topics), perioperative (8 topics) and intraoperative (3 topics) management, and postoperative care (10 topics).

CONCLUSION

These recommendations should ease and promote the multidisciplinary management of older subjects with HF by integrating the expertise of different specialists. By providing a convenient list of topics of interest, they might assist in identifying unmet needs and research priorities.

Meta-analyses of gabapentinoids for pain management after knee arthroplasty: A caveat emptor? A narrative review

The use of gabapentinoids for perioperative pain management after total knee arthroplasty has been the subject of nine systematic reviews and meta-analyses. A critical analysis of the clinical aspects of the methodology of these publications shows major flaws which limit the interpretation for the recommended use of perioperative gabapentinoids in pain management for unilateral primary total knee arthroplasty. Consequently, readers and authors of systematic reviews and meta-analyses should critically assess the clinical aspects of the included studies.

Anesthesia Method, Tourniquet Use, and Persistent Postsurgical Pain after Total Knee Arthroplasty: A Prespecified Secondary Analysis of a Randomized Trial

BACKGROUND

Persistent postsurgical pain after total knee arthroplasty is a common problem and a major reason for patient dissatisfaction. This secondary analysis aimed to investigate the effects of anesthesia (spinal vs. general) and tourniquet use on persistent pain after total knee arthroplasty.

METHODS

In this secondary analysis of a previously presented parallel, single-center, randomized trial, 404 patients scheduled for total knee arthroplasty were randomized to spinal versus general anesthesia and no-tourniquet versus tourniquet groups. Patients assessed pain using the Brief Pain Inventory-short form preoperatively and 3 and 12 months postoperatively. The prespecified main outcome was the change in "average pain" measured with numerical 0 to 10 rating scale 1 yr postoperatively. The threshold for clinical importance between groups was set to 1.0.

RESULTS

The change in average pain scores 1 yr postoperatively did not differ between the spinal and general anesthesia groups (-2.6 [SD 2.5] vs. -2.3 [SD 2.5], respectively; mean difference, -0.4; 95% CI, -0.9 to 0.1; P = 0.150). The no-tourniquet group reported a smaller decrease in the average pain scores than the tourniquet group (-2.1 [SD 2.7] vs. -2.8 [SD 2.3]; mean difference, 0.6; 95% CI, 0.1 to 1.1; P = 0.012). After 1 yr, the scores concerning the mean of four pain severity variables (numerical rating scale) decreased more in the spinal than in the general anesthesia group (-2.3 [SD 2.2] vs. -1.8 [SD 2.1]; mean difference, -0.5; 95% CI, -0.9 to -0.05; P = 0.029) and less in the no-tourniquet than in the tourniquet group (-1.7 [SD 2.3] vs. -2.3 [SD 2.0]; mean difference, 0.6; 95% CI, 0.2 to 1.0; P = 0.005). None of the differences in pain scores reached the threshold for clinical importance.

CONCLUSIONS

The type of anesthesia (spinal vs. general) or tourniquet use has no clinically important effect on persistent postsurgical pain after total knee arthroplasty.

EDITOR’S PERSPECTIVE

Influence of inpatient opioid consumption on persistent use following total knee arthroplasty

BACKGROUND

Total knee arthroplasty (TKA) is associated with a high incidence of continued opioid use beyond the expected period of recovery. The aim of this study was to determine the influence of inpatient opioid consumption on the development of persistent use.

METHODS

Opioid-naïve patients undergoing primary, uncomplicated TKA were included in a prospective, observational study at a single institution. Postoperatively, opioids were prescribed by orthopedic advanced practitioners or resident physicians and administered by registered nurses. Individual inpatient prescriptions were adjusted, as needed, to facilitate optimal recovery conditions. Average hourly inpatient opioid consumption was calculated from total usage between midnight on the day of surgery until the time of hospital discharge. Persistent opioid use was defined as a prescription refill written by the orthopedic surgeon at the 6-week surgical follow-up visit. A multivariable regression model was used to identify independent risk factors associated with persistent use.

RESULTS

A total of 351 patients were included in the analysis. Persistent opioid use was identified in 17.4% (61) of patients overall. A history of alcohol abuse (OR 7.80; 95% CI 2.13 to 28.55, p=0.002) was identified as an independent risk factor. Inpatient opioid consumption in the top quartile (equivalent to more than 10 mg of oxycodone every 4 hours) was not found to be associated with persistent use.

CONCLUSION

Larger amounts of opioid consumed in the hospital following uncomplicated, primary TKA may not be associated with an increased risk of persistent use at 6 weeks among opioid-naïve patients. Patients may have unique risk factors for prolonged opioid use that may not necessarily be apparent in the early postoperative period.

Standardized Care Pathways as a Means to Improve Patient Safety

The literature overwhelmingly supports standardized, evidence-based care to improve patient safety in the surgical setting, including checklists and enhanced recovery programs. Although local culture, patient complexity, and hospital setting can represent barriers to implanting standardized practices, they can be overcome with thoughtful strategies.

Perioperative Nonsteroidal Anti-Inflammatory Agents in the COVID-19 Orthopedic Patient

BACKGROUND

SARS-CoV-2 infection can cause serious complications beyond lung injury and respiratory failure, including sepsis, cardiovascular injury, renal failure, coagulation abnormalities, and neurologic injury. Widely used medications such as nonsteroidal anti-inflammatory drugs (NSAIDs) have been flagged as having the potential to cause harm in the context of COVID-19. It is unknown if the benefits of NSAID use in the orthopedic population will outweigh the potential risks of increased morbidity in COVID-19 orthopedic patients.

METHODS

We conducted a narrative review of the use of NSAIDs in the orthopedic patient with COVID-19, focusing on the effects of NSAIDs on the inflammatory process, the role of NSAIDs in orthopedics, and the associations between NSAID use and complications of pneumonia.

RESULTS

We found that it may be appropriate to consider NSAID use in otherwise healthy orthopedic patients with COVID-19 and significant pain.

CONCLUSIONS

In this context, we recommend that NSAIDs be used at the lowest effective dose for the shortest duration possible in orthopedic patients with COVID-19. However, pending further data and based on the concerns outlined in this review, we recommend avoiding NSAIDs in orthopedic patients with significant comorbidities and those who are undergoing major orthopedic surgery.

Nach Einführung des PPV-Maßnahmenbündels (1. Patient*innenseminar, 2. spezifische Chirurgietechnik, 3. spezifische Anästhesietechnik, 4. Physiotherapiebeginn am Operationstag) wurden 34 Patient*innen mit elektiver Knietotalendoprothese prospektiv untersucht und mit „matched-pair“-Kontrollen verglichen. Endpunkte sind Dauer der Einleitungszeit (primär) und Krankenhausverweildauer, Ruhe- und Belastungsschmerz am 1. postoperativen Tag (numerische Analogskala), und Mobilisationsfortschritt (MBF) an den postoperativen Tagen 1, 3 und 6 (sekundär). Gruppenvergleiche wurden mit Wilcoxon-Mann-Whitney-Tests auf Nichtunterlegenheit durchgeführt. Im Fall von Nichtunterlegenheit wurde anschließend auf Überlegenheit getestet.

Ergebnisse

Die Einleitungszeit in der PPV-Gruppe betrug im Median 13,5 min (Kontrollgruppe: 60 min, p < 0,0001), die Krankenhausverweildauer betrug in der PPV-Gruppe 8 Tage (Kontrollgruppe: 12 Tage, p < 0,0001). Am ersten postoperativen Tag betrug die mediane Ruheschmerzstärke in der PPV-Gruppe 30 (Kontrollgruppe: 20); die Belastungsschmerzstärke war in beiden Gruppen gleich (Median 40). Die Mobilisation der Patienten*innen der PPV-Gruppe gelang an den postoperativen Tagen 1, 3 und 6 besser (jeweils p < 0,0001).

Schlussfolgerung

Das Konzept der patient*innenzentrierten perioperativen Versorgung (PPV) erscheint vielversprechend genug, um weitere klinische Studien zu rechtfertigen.

Individualized Fluid Management Using the Pleth Variability Index: A Randomized Clinical Trial

BACKGROUND

The present trial was designed to assess whether individualized strategies of fluid administration using a noninvasive plethysmographic variability index could reduce the postoperative hospital length of stay and morbidity after intermediate-risk surgery.

METHODS

This was a multicenter, randomized, nonblinded parallel-group clinical trial conducted in five hospitals. Adult patients in sinus rhythm having elective orthopedic surgery (knee or hip arthroplasty) under general anesthesia were enrolled. Individualized hemodynamic management aimed to achieve a plethysmographic variability index under 13%, and the standard management strategy aimed to maintain a mean arterial pressure above 65 mmHg during general anesthesia. The primary outcome was the postoperative hospital length of stay decided by surgeons blinded to the group allocation of the patient.

RESULTS

In total, 447 patients were randomized, and 438 were included in the analysis. The mean hospital length of stay ± SD was 6 ± 3 days for the plethysmographic variability index group and 6 ± 3 days for the control group (adjusted difference, 0.0 days; 95% CI, -0.6 to 0.5; P = 0.860); the theoretical postoperative hospital length of stay was 4 ± 2 days for the plethysmographic variability index group and 4 ± 1 days for the control group (P = 0.238). In the plethysmographic variability index and control groups, serious postoperative cardiac complications occurred in 3 of 217 (1%) and 2 of 224 (1%) patients (P = 0.681), acute postoperative renal failure occurred in 9 (4%) and 8 (4%) patients (P = 0.808), the troponin Ic concentration was more than 0.06 μg/l within 5 days postoperatively for 6 (3%) and 5 (2%) patients (P = 0.768), and the postoperative arterial lactate measurements were 1.44 ± 1.01 and 1.43 ± 0.95 mmol/l (P = 0.974), respectively.

CONCLUSIONS

Among intermediate-risk patients having orthopedic surgery with general anesthesia, fluid administration guided by the plethysmographic variability index did not shorten the duration of hospitalization or reduce complications.

Enhanced Recovery after Lumbar Spine Fusion

Background

Prospective trials of enhanced recovery after spine surgery are lacking. We tested the hypothesis that an enhanced recovery pathway improves quality of recovery after one- to two-level lumbar fusion.

Methods

A patient- and assessor-blinded trial of 56 patients randomized to enhanced recovery (17 evidence-based pre-, intra-, and postoperative care elements) or usual care was performed. The primary outcome was Quality of Recovery-40 score (40 to 200 points) at postoperative day 3. Twelve points defined the clinically important difference. Secondary outcomes included Quality of Recovery-40 at days 0 to 2, 14, and 56; time to oral intake and discharge from physical therapy; length of stay; numeric pain scores (0 to 10); opioid consumption (morphine equivalents); duration of intravenous patient-controlled analgesia use; complications; and markers of surgical stress (interleukin 6, cortisol, and C-reactive protein).

Results

The analysis included 25 enhanced recovery patients and 26 usual care patients. Significantly higher Quality of Recovery-40 scores were found in the enhanced recovery group at postoperative day 3 (179 ± 14 vs. 170 ± 16; P = 0.041) without reaching the clinically important difference. There were no significant differences in recovery scores at days 0 (175 ± 16 vs. 162 ± 22; P = 0.059), 1 (174 ± 18 vs. 164 ± 15; P = 0.050), 2 (174 ± 18 vs. 167 ± 17; P = 0.289), 14 (184 ± 13 vs. 180 ± 12; P = 0.500), and 56 (187 ± 14 vs. 190 ± 8; P = 0.801). In the enhanced recovery group, subscores on the Quality of Recovery-40 comfort dimension were higher (longitudinal mean score difference, 4; 95% CI, 1, 7; P = 0.008); time to oral intake (−3 h; 95% CI, −6, −0.5; P = 0.010); and duration of intravenous patient-controlled analgesia (−11 h; 95% CI, −19, −6; P &lt; 0.001) were shorter; opioid consumption was lower at day 1 (−57 mg; 95% CI, −130, −5; P = 0.030) without adversely affecting pain scores (−2; 95% CI, −3, 0; P = 0.005); and C-reactive protein was lower at day 3 (6.1; 95% CI, 3.8, 15.7 vs. 15.9; 95% CI, 6.6, 19.7; P = 0.037).

Conclusions

Statistically significant gains in early recovery were achieved by an enhanced recovery pathway. However, significant clinical impact was not demonstrated.

An enhanced recovery after surgery pathway: association with rapid discharge and minimal complications after anterior cervical spine surgery

OBJECTIVEEnhanced recovery after surgery (ERAS) pathways are associated with improved outcomes, lower morbidity and complications, and higher patient satisfaction in multiple surgical subspecialties. Despite these gains, there are few data to guide the application of ERAS concepts to spine surgery. The authors report the development and implementation of the first ERAS pathway for patients undergoing anterior cervical discectomy and fusion (ACDF) and cervical disc arthroplasty (CDA).METHODSThis was a retrospective cohort study of prospectively collected data. The authors created a multidisciplinary pathway based on best available evidence for interventions that positively influence outcomes after anterior cervical spine surgery. Patients were followed prospectively up to postoperative day 90. Patient data were collected via electronic medical record review and included demographics, comorbidities, baseline and perioperative opioid use, postoperative complications, and length of hospital stay (LOS). ERAS process measures and compliance with pathway elements were also tracked.RESULTSThirty-three patients were cared for under the pathway (n = 25 ACDF; n = 8 CDA). The median LOS was 416 minutes (interquartile range [IQR] 210-1643 minutes). Eight patients required an extended stay-longer than 23 hours. Reasons for extended admission included pain (n = 4), dyspnea (n = 1), hypoxia (n = 1), hypertension (n = 1), and dysphagia (n = 1). The median LOS for the 8 patients who required extended monitoring prior to discharge was 1585 minutes (IQR 1423-1713 minutes). Overall pathway compliance with included process measures was 85.6%. The median number of ERAS process elements delivered to each patient was 18. There was no strong association between LOS and number of ERAS process elements provided (Pearson's r = -0.20). Twelve percent of the cohort was opioid tolerant on the day of surgery. There were no significant differences between total intraoperatively or postanesthesia care unit-administered opioid, or LOS, between opioid-tolerant and opioid-naïve patients. There were no complications requiring readmission.CONCLUSIONSAn ERAS pathway for anterior cervical spine surgery facilitates safe, prompt discharge. The ERAS pathway was associated with minimal complications, and no readmissions within 90 days of surgery. Pain and respiratory compromise were both linked with extended LOS in this cohort. Further prospective studies are needed to confirm the potential benefits of ERAS for anterior cervical spine surgery, including longer-term complications, cost, and functional outcomes.

Proposed pathway for patients undergoing enhanced recovery after spinal surgery: protocol for a systematic review

BACKGROUND

The best evidence-enhanced recovery care pathway is yet to be defined for patients undergoing spinal surgery. Minimally invasive surgery, multimodal analgesia, early mobilization, and early postoperative nutrition have been considered as critical components of enhanced recovery in spinal surgery (ERSS). The objective of this study will be to synthesize the evidence underpinning individual components of a proposed multidisciplinary enhanced recovery pathway for patients undergoing spinal surgery.

METHODS

This is the study protocol for a systematic review of complex interventions. Our team identified 22 individual care components of a proposed pathway based on clinical practice guidelines and published reviews. We will include systematic reviews and meta-analysis, randomized controlled trials, non-randomized controlled trials, and observational studies in adults or pediatric patients evaluating any one of the pre-determined care components. Our primary outcomes will be all-cause mortality, morbidity outcomes (e.g., pulmonary, cardiac, renal, surgical complications), patient-reported outcomes and experiences (e.g., pain, quality of care experience), and health services outcomes (e.g., length of stay and costs). We will search the following databases (1990 onwards) MEDLINE, EMBASE, and Cochrane Library (Cochrane Database of Systematic Reviews and CENTRAL). Two reviewers will independently screen all citations, full-text articles, and abstract data. Potential conflicts will be resolved through discussion. The risk of bias for individual studies will be appraised using appropriate tools. A narrative synthesis will be provided with the information presented in the text and tables to summarize and explain the characteristics and findings of the included studies. Due to clinical and methodological heterogeneity, we do not anticipate to conduct meta-analyses. Confidence in cumulative evidence for each component of care will be classified according to the GRADE system.

DISCUSSION

This systematic review will identify, evaluate, and integrate the evidence underpinning individual components of a pathway for patients undergoing spinal surgery. The formation of an evidence-based pathway will allow for the standardization of clinical care delivery within the context of enhanced recovery in spinal surgery.

Establishing a patient centered, outpatient total joint home recovery program within an integrated healthcare system

Outpatient total joint home recovery (HR) is a rapidly growing initiative being developed and employed at high volume orthopedic centers. Minimally invasive surgery, improved pain control and home health services have made HR possible. Multidisciplinary teams with members ranging from surgeons and anesthesiologists to hospital administrators, physical therapists, nurses and research analysts are necessary for success. Eligibility criteria for outpatient total joint arthroplasty will vary between medical centers. Surgeon preference in addition to medical comorbidities, social support, preoperative patient mobility and safety of the HR location are all factors to consider when selecting patients for outpatient total joint HR. As additional knowledge is gained, the next steps will be to establish 'best practices' and speciality society-endorsed guidelines for patients undergoing outpatient total joint arthroplasty.

Lower limb joint repair and replacement: an overview

In the last few years, much has been published concerning total joint arthroplasty, and debates and discussions to new questions and points of view started many years ago. In this commentary, we report the latest evidence of best practice in the field of lower limb arthroplasty; this evidence is based on a literature search conducted by using PubMed and Scopus databases with a time limit of five years. We found novel evidence regarding cemented and not cemented implant, implant design, anticoagulant use, tourniquets, and other aspects of joints replacement surgery that we consider a common part of modern orthopedic practice. We specifically focus on lower limb joint replacement.
