Kuyl EV, Parel PM, Agarwal AR, Gu A, Harris AB, Rao S, Golladay GJ, Thakkar SC. The Association Between Oral Bone Mineral Density-Reducing Medications and the Risk of 2-Year Implant-Related Complications Following Total Knee Arthroplasty. J Arthroplasty 2024; 39:S205-S211.e1. [PMID: 38467202 DOI: 10.1016/j.arth.2024.03.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/15/2023] [Revised: 02/29/2024] [Accepted: 03/04/2024] [Indexed: 03/13/2024] Open
Abstract
BACKGROUND Certain medications interfere with the bone remodeling process and may potentially increase the risk of complications after total knee arthroplasty (TKA). As patients undergoing TKA may be taking these bone mineral density (BMD)-reducing medications, it is unclear as to whether and which medications impact TKA outcomes. Therefore, the purpose of this study was to observe the impact of various BMD-reducing medications on 2-year implant-related complications following TKA. METHODS A retrospective analysis of patients undergoing primary TKA was conducted using a national administrative claims database. Patients were identified if they were taking any known BMD-reducing medication and were compared to control patients. To control for confounders associated with taking multiple agents, multivariable logistic regression analyses were conducted for each 2-year outcome (all-cause revision, loosening-indicated revision, and periprosthetic fracture--indicated revision), with the output recorded as odds ratios (ORs). RESULTS In our study, 502,927 of 1,276,209 TKA patients (39.4%) were taking at least one BMD-reducing medication perioperatively. On multivariable analysis, medications associated with a higher likelihood of 2-year all-cause revision included first- and second-generation antipsychotics (SGAs) (OR: 1.42 and 1.26, respectively), selective serotonin reuptake inhibitors (SSRIs) (OR: 1.14), glucocorticoids (1.13), and proton pump inhibitors (PPIs) (OR: 1.23) (P < .05 for all). Medications associated with a higher likelihood of 2-year periprosthetic fracture included SGAs (OR: 1.51), SSRIs (OR: 1.27), aromatase inhibitors (OR: 1.29), and PPIs (OR: 1.42) (P < .05 for all). CONCLUSIONS Of the drug classes observed, the utilization of perioperative PPIs, SSRIs, glucocorticoids, first-generation antipsychotics, and SGAs was associated with the highest odds of all-cause revision. Our findings suggest a relationship between these medications and BMD-related complications; however, further studies should seek to determine the causality of these relationships.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVE The purpose was to compare rates of postoperative ED visits, readmission, and reoperation between patients with and without preexisting mental illness undergoing outpatient anterior cervical discectomy and fusion (ACDF). METHODS A retrospective review of the Mariner Database was conducted on patients who underwent ACDF between 2010 and 2017. Exclusion criteria included same day revision surgery and patients with a history of spine infection, trauma, or neoplasm. Patients were grouped into 3 categories: those with existing history of anxiety and/or depression, those with severe mental illness, and those without any history of mental illness. Severe mental illness was defined as a combination of diagnosis including schizophrenia, bipolar disorder, and/or psychotic disorder. Outcome measures were analyzed by comparing groups using multivariate logistic regression. Significance was set at P < 0.05. RESULTS Patients with anxiety/depression and patients with severe mental illness both had significantly increased risk of ED visits and readmission at 30-day and 90-day intervals. Compared to patients without mental illness, patients with severe mental illness (OR 1.93, P < 0.001) had significantly increased rates of reoperation at 90-days and 1-years postoperatively. Patients with anxiety/depression did not have increased rates of reoperation relative to patients without anxiety/depression at any time interval (P > 0.05). CONCLUSION Anxiety/depression as well as more severe psychiatric disease such as Schizophrenia and Bipolar disorder were significantly associated with increased healthcare utilization following outpatient ACDF. Patients with preexisting mental illness undergoing outpatient ACDF should be carefully evaluated preoperatively and closely followed postoperatively to reduce risk of adverse events.

A Systematic Review Evaluating Outcomes, Healthcare Use, and Patient-reported Outcome Measures. Clin Orthop Relat Res 2023; 481:947-964. [PMID: 36730492 PMCID: PMC10097587 DOI: 10.1097/corr.0000000000002481] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/01/2022] [Accepted: 10/12/2022] [Indexed: 02/04/2023]
Abstract
BACKGROUND Studies evaluating the effects of a psychiatric illness on orthopaedic surgical outcomes have yielded mixed results. Because awareness of patient comorbid mental health disorders has become increasingly important to tailor treatment plans, the aim of our systematic review was to present the findings of all studies reporting on the association between clinically diagnosed psychiatric illnesses and total joint arthroplasty (TJA) outcomes and evaluate the quality of evidence to provide a comprehensive summary. QUESTION/PURPOSE Is there a consistently reported association between comorbid psychiatric illness and (1) complication risk, (2) readmission rates, (3) healthcare use and discharge disposition, and (4) patient-reported outcome measures (PROMs) after TJA? METHODS The PubMed, EBSCO host, Medline, and Google Scholar electronic databases were searched on April 9, 2022, to identify all studies that evaluated outcomes after TJA in patients with a comorbid clinically diagnosed mental health disorder between January 1, 2000, and April 1, 2022. Studies were included if the full-text article was available in English, reported on primary TJA outcomes in patients with clinically diagnosed mental health disorders, included patients undergoing TJA without a psychiatric illness for comparison, and had a minimum follow-up time of 30 days for evaluating readmission rates, 90 days for other perioperative outcomes such as length of stay and complications, and 1-year minimum follow-up if assessing PROMs. Studies that used a mental health screening examination instead of clinical diagnoses were excluded to isolate for verified psychiatric illnesses. Additionally, systematic reviews, case reports, duplicate studies between the databases, and gray literature were excluded. Twenty-one studies were included in our final analysis comprising 31,023,713 patients with a mean age range of 57 to 69 years. Mental health diagnoses included depression, anxiety, bipolar disorder, schizophrenia, major personality disorder, and psychosis as well as concomitant mental disorders. Two reviewers independently evaluated the quality of included studies using the Methodological Index for Nonrandomized Studies (MINORS) tool. The mean MINORS score was 19.5 ± 0.91 of 24, with higher scores representing better study quality. All the articles included were retrospective, comparative studies. Given the heterogeneity of the included studies, a meta-analysis was not performed, and results are instead presented descriptively. RESULTS Patients with schizophrenia were consistently reported to have higher odds of medical and surgical complications than patients without psychiatric illness, particularly anemia and respiratory complications. Among studies with the largest sample sizes, patients with depression alone or depression and anxiety had slightly higher odds of complications. Most studies identified higher odds of readmission among patients with depression, schizophrenia, and severe mental illness after TJA. However, for anxiety, there was no difference in readmission rates compared with patients without psychiatric illness. Slightly higher odds of emergency department visits were reported for patients with depression, anxiety, concomitant depression and anxiety, and severe mental illness across studies. When evaluating healthcare use, articles with the largest sample sizes reporting on depression and length of stay or discharge disposition found modestly longer length of stay and greater odds of nonhome discharge among patients with depression. Although several studies reported anxiety was associated with slightly increased total costs of hospitalization, the most robust studies reported no difference or slightly shorter average length of stay. However, the included studies only reported partial economic analyses of cost, leading to relatively superficial evidence. Patients with schizophrenia had a slightly longer length of stay and modestly lower odds of home discharge and cost. Likewise, patients with concomitant depression and anxiety had a slightly longer average length of stay, according to the two articles reporting on more than 1000 patients. Lastly, PROM scores were worse in patients with depression at a minimum follow-up of 1 year after TJA. For anxiety, there was no difference in improvement compared with patients without mental illness. CONCLUSION Our systematic review found that individuals with psychiatric illness had an increased risk of postoperative complications, increased length of stay, higher costs, less frequent home discharge, and worse PROM scores after TJA. These findings encourage inclusion of comorbid psychiatric illness when risk-stratifying patients. Attention should focus on perioperative interventions to minimize the risk of thromboembolic events, anemia, bleeding, and respiratory complications as well as adequate pain management with drugs that do not exacerbate the likelihood of these adverse events to minimize emergency department visits and readmissions. Future studies are needed to compare patients with concomitant psychiatric illnesses such as depression and anxiety with patients with either diagnosis in isolation, instead of only comparing patients with concomitant diagnoses with patients without any psychiatric illnesses. Similarly, the results of targeted interventions such as cognitive behavioral therapy are needed to understand how orthopaedic surgeons might improve the quality of care for patients with a comorbid psychiatric illness.

Postsurgical morbidity and mortality favorably informs deep brain stimulation for new indications including schizophrenia and schizoaffective disorder. Front Surg 2023; 10:958452. [PMID: 37066004 PMCID: PMC10098000 DOI: 10.3389/fsurg.2023.958452] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Accepted: 03/07/2023] [Indexed: 04/18/2023] Open
Abstract
Background Deep brain stimulation (DBS) shows promise for new indications like treatment-refractory schizophrenia in early clinical trials. In the first DBS clinical trial for treatment refractory schizophrenia, despite promising results in treating psychosis, one of the eight subjects experienced both a symptomatic hemorrhage and an infection requiring device removal. Now, ethical concerns about higher surgical risk in schizophrenia/schizoaffective disorder (SZ/SAD) are impacting clinical trial progress. However, insufficient cases preclude conclusions regarding DBS risk in SZ/SAD. Therefore, we directly compare adverse surgical outcomes for all surgical procedures between SZ/SAD and Parkinson's disease (PD) cases to infer relative surgical risk relevant to gauging DBS risks in subjects with SZ/SAD. Design In the primary analysis, we used browser-based statistical analysis software, TriNetX Live (trinetx.com TriNetX LLC, Cambridge, MA), for Measures of Association using the Z-test. Postsurgical morbidity and mortality after matching for ethnicity, over 39 risk factors, and 19 CPT 1003143 coded surgical procedures from over 35,000 electronic medical records, over 19 years, from 48 United States health care organizations (HCOs) through the TriNetX Research Network™. TriNetXis a global, federated, web-based health research network providing access and statistical analysis of aggregate counts of deidentified EMR data. Diagnoses were based on ICD-10 codes. In the final analysis, logistic regression was used to determine relative frequencies of outcomes among 21 diagnostic groups/cohorts being treated with or considered for DBS and 3 control cohorts. Results Postsurgical mortality was 1.01-4.11% lower in SZ/SAD compared to the matched PD cohort at 1 month and 1 year after any surgery, while morbidity was 1.91-2.73% higher and associated with postsurgical noncompliance with medical treatment. Hemorrhages and infections were not increased. Across the 21 cohorts compared, PD and SZ/SAD were among eight cohorts with fewer surgeries, nine cohorts with higher postsurgical morbidity, and fifteen cohorts within the control-group range for 1-month postsurgical mortality. Conclusions Given that the subjects with SZ or SAD, along with most other diagnostic groups examined, had lower postsurgical mortality than PD subjects, it is reasonable to apply existing ethical and clinical guidelines to identify appropriate surgical candidates for inclusion of these patient populations in DBS clinical trials.

Relationship Between Mental Health Disorders and Readmissions Following Total Joint Arthroplasty: A Systematic Review and Meta-Analysis. J Arthroplasty 2023; 38:188-193.e1. [PMID: 35987494 DOI: 10.1016/j.arth.2022.08.017] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/22/2022] [Revised: 08/07/2022] [Accepted: 08/10/2022] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND There is limited evidence exploring the relationship between mental health disorders and the readmissions following total joint arthroplasty (TJA). Therefore, we conducted a meta-analysis to evaluate the relationship between mental health disorders and the risk of readmission following TJA. METHODS We searched PubMed, Cochrane, and Google Scholar from their inception till April 19, 2022. Studies exploring the association of mental health disorders and readmission risk following TJA were selected. The outcomes were divided into 30-day readmission, 90-day readmission, and readmission after 90 days. We also performed subgroup analyses based on the type of arthroplasty: total hip arthroplasty (THA) and total knee arthroplasty (TKA). A total of 12 studies were selected, of which 11 were included in quantitative analysis. A total of 1,345,893 patients were evaluated, of which 73,953 patients suffered from mental health disorders. RESULTS The risk of 30-day readmission (odds ratio = 1.43, 95% CI 1.14-1.80, P = .002, I2 = 87%) and 90-day readmission (OR = 1.35, 95% CI 1.22-1.49, P < .00001, I2 = 89%) was significantly associated with mental health disorders. On subgroup analyses, 30-day readmission was significantly associated with THA (OR = 1.29, 95% CI 1.04-1.60, P = .02), but not with TKA (OR = 1.44, 95% CI 0.51-4.06, P = .50). Similarly, 90-day readmission was significantly associated with both THA (OR = 1.21, 95% CI 1.14-1.29, P < .00001) and TKA (OR = 1.33, 95% CI 1.17-1.51, P < .0001). CONCLUSION Mental health disorders are significantly associated with increased 30-day and 90-day readmissions. Increasing awareness regarding mental health disorders and readmission in arthroplasty will help in efficient preoperative risk stratification and better postoperative management in these patients.

Abstract
The incidence of postoperative pneumonia (POP) in patients with cancer is high, but its incidence following major cancer surgeries is unclear. Therefore, we investigated the incidence and risk factors of POP after surgery in patients with the five most common cancers in Korea using a common data model (CDM). Patients aged >19 years who underwent gastric, colon, liver, lung, or breast cancer surgery between January 2011 and December 2020 were included, excluding patients who underwent chemotherapy or radiotherapy. Pneumonia was defined as a pneumonia diagnosis code in patients hospitalized postoperatively. Gastric, colon, lung, breast, and liver cancers were noted in 4004 (47.4%), 622 (7.4%), 2022 (24%), 958 (11.3%), and 839 (9.9%) of 8445 patients, respectively. The cumulative POP incidence was 3.1% (n = 262), with the highest incidence in lung cancer (n = 91, 4.5%), followed by gastric (n = 133, 3.3%), colon (n = 19, 3.1%), liver (n = 14, 1.7%), and breast (n = 5, 0.5%) cancers. In multivariable analysis, older age, male sex, history of chronic pulmonary disease, mood disorder, and cerebrovascular disease were POP predictors. The cumulative POP incidence in the five cancers using the CDM was approximately 3%. Older age, male sex, chronic pulmonary disease, mood disorder, and cerebrovascular disease were POP risk factors in patients with cancer.

Abstract
Background and Objectives: For some years, psychiatric illness has been a major factor in evaluating the results of total knee arthroplasty. As with other patient-related items, patients diagnosed with mental illness have higher costs of medical treatment, longer recovery, and longer hospital stays. The aim of this paper is to evaluate the role of mental diseases on the surgical outcome compared with the normal population. Materials and Methods: At our hospital, we undertook a retrospective study between June 2020 and January 2022. The experimental group consisted of patients with mental diseases including schizophrenia, bipolar disease, depression, substance uses, or other psychiatric disorders. The control group consisted of patients who underwent total knee arthroplasty and did not have a mental disease. Postoperative complications and length of stay were also recorded during the study. We used the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the Knee Society Score (KSS) as outcome measures. Results: Between June 2020 and January 2022, a total of 634 patients underwent total knee arthroplasty in our clinic, of which 239 had a mental disease. The majority of patients were female (61%), and the average length of stay was significantly longer for patients with mental illness (6.8 vs. 2.8 days). Preoperative WOMAC and KS function scores demonstrated statistically significant differences between groups (67.83 ± 17.8 vs. 62.75 ± 15.7 and 29.31 ± 19.8 vs. 34.98 ± 21.3). KS knee score did not show any significant differences preoperatively. All postoperative functional scores showed significantly better results for the control group compared to the mental illness group. Conclusions: Mental illness appears to be linked with lower TKA scores before and after the surgical procedure.

Abstract
Revision total hip arthroplasty (rTHA) after septic failure is associated with higher morbidity and mortality compared with aseptic revisions. The goals of this study were to characterize (1) the in-hospital mortality rate for patients with septic rTHA, (2) the effect of hospital hip revision surgery volume (HRV) on mortality after septic rTHA, and (3) the independent risk factors associated with in-hospital mortality rates after rTHA with 2-year follow-up. The authors analyzed the Healthcare Cost and Utilization Project State Inpatient Databases of New York and Florida to identify cases of septic rTHA from 2007 to 2012 with International Classification of Diseases, Ninth Revision, codes. The authors included patients with (1) no history of THA for 2 years before the index admission and (2) 2 years of follow-up. Groups with primary THA and aseptic rTHA were identified as control groups. Logistic regression was used to evaluate independent associations. Of 3057 patients with septic rTHA, 5.2% (n=160) had in-hospital mortality vs 2.9% of those with primary THA (n=3525, P=.0001) and 2.1% of those with aseptic rTHA (n=252, P=.0001). Octogenarian status, medium-risk Elixhauser comorbidity score, and high-risk Elixhauser comorbidity score were independent risk factors for mortality (adjusted odds ratio [AOR]=1.587, 95% CI=1.103-2.282, P=.0128; AOR=2.439, 95% CI=1.680-3.541, P<.0001; and AOR=6.367, 95% CI=4.134-9.804, P<.0001, respectively). Undergoing rTHA in a high-HRV hospital was associated with lower odds of in-hospital mortality (AOR=0.539, 95% CI=0.332-0.877, P=.0127). Receiving care in a low-HRV hospital increased the risk of 2-year postoperative patient mortality. Similarly, older age and a higher comorbidity burden were independently associated with increased 2-year postoperative mortality. [Orthopedics. 2022;45(1):57-63.].

Abstract
BACKGROUND The effect of pre-existing mental illness on outpatient surgical outcomes is not well characterized. The objective of this study was to evaluate the association between pre-existing mental illness diagnosis and postoperative complications after outpatient total knee (TKA) and total hip arthroplasty (THA) and 2) compare with inpatient total joint arthroplasty (TJA). METHODS The Mariner Claims Database was used to capture patients undergoing outpatient TJA from 2010 to 2017. Patients were grouped into three categories: those with an existing history of anxiety and/or depression, those with severe mental illness, and those without history of mental illness. Additional subgroup analysis compared those with severe mental illness undergoing outpatient vs inpatient TJA. Outcomes were analyzed using multivariable logistic regression (P < .05). RESULTS Patients undergoing outpatient TJA with prior history of anxiety and/or depression or severe mental illness had an increased risk of emergency department (ED) visits (TKA, P < .001; THA, P = .014) within 90 days compared with those without history of mental illness. Severe mental illness was also associated with increased risk of medical complications at 90 days (TKA, P < .001; THA, P = .006). When compared with those undergoing inpatient surgery, patients undergoing outpatient TKA with severe mental illness were at increased risk of periprosthetic infection (P = .005) and ED visit (P = .003) within 90 days of surgery. CONCLUSION Anxiety/depression and severe mental illness are associated with higher rates of ED visits after outpatient TJA. Patients with severe mental illness also experienced more adverse events, whereas those with anxiety and/or depression had similar rates compared with control. A higher rate of adverse outcomes was seen after TKA in patients with severe mental illness when surgery was performed in the outpatient setting vs those that had surgery as an inpatient.

Abstract
» In 2016, a total of 48,771 hospital-acquired conditions (HACs) were reported in U.S. hospitals. These incidents resulted in an excess cost of >$2 billion, which translates to roughly $41,000 per patient per HAC. » In the settings of total hip arthroplasty (THA) and total knee arthroplasty (TKA), increased age, a body mass index of >35 kg/m2, male sex, diabetes mellitus, electrolyte disturbances, and a history of anemia increase the likelihood of surgical site infections. » Institution-specific (surgical) risk factors such as increased tourniquet time, an operative time of >130 minutes, bilateral procedures, a femoral nerve block, and general anesthesia increase the risk of HACs in the settings of THA and TKA.

Abstract
INTRODUCTION Studies have shown that antipsychotic medication use may lead to venous thromboembolisms (VTEs); however, this association has not been demonstrated in patients undergoing primary total knee arthroplasty (TKA). Therefore, the purpose of this study was to investigate whether patients taking antipsychotic medications at the time of their primary TKA have higher rates of in-hospital lengths of stay (LOS), VTEs, and costs of care. METHODS Patients taking antipsychotic medications were identified and matched to a cohort in a 1:5 ratio by age, sex, and medical comorbidities. Patients who had a history of VTEs or hypercoagulable states before their TKA were excluded. The query resulted in 439,579 patients within the study (n = 73,285) and matching cohorts (n = 366,294). Outcomes analyzed included rates of in-hospital LOS, VTEs, and costs of care. A P value less than 0.01 was considered statistically significant. RESULTS We found statistically significant longer in-hospital LOS for patients taking antipsychotic medications (3.27 versus 3.02 days, P < 0.0001). Study patients were also found to have a higher incidence and odds ratio of VTEs (2.37 versus 1.04%; odds ratio: 1.86, 95% confidence interval: 1.75-1.97, P < 0.0001). Ninety-day costs of care were also significantly higher in the study cohort ($17,332.70 versus $15,975.00, P < 0.0001). CONCLUSION After adjusting for confounders, patients taking antipsychotic medication were found to have higher rates of in-hospital LOS, VTEs, and costs of care. The study can be used by orthopaedic surgeons to counsel patients taking these medications concerning the potential complications after their procedure.

Abstract
BACKGROUND Psychiatric comorbidity is known to impact upon use of nonpsychiatric health services. The aim of this systematic review and meta-analysis was to assess the specific impact of severe mental illness (SMI) on the use of inpatient, emergency, and primary care services for nonpsychiatric medical disorders. METHODS AND FINDINGS PubMed, Web of Science, PsychINFO, EMBASE, and The Cochrane Library were searched for relevant studies up to October 2018. An updated search was carried out up to the end of February 2020. Studies were included if they assessed the impact of SMI on nonpsychiatric inpatient, emergency, and primary care service use in adults. Study designs eligible for review included observational cohort and case-control studies and randomised controlled trials. Random-effects meta-analyses of the effect of SMI on inpatient admissions, length of hospital stay, 30-day hospital readmission rates, and emergency department use were performed. This review protocol is registered in PROSPERO (CRD42019119516). Seventy-four studies were eligible for review. All were observational cohort or case-control studies carried out in high-income countries. Sample sizes ranged from 27 to 10,777,210. Study quality was assessed using the Newcastle-Ottawa Scale for observational studies. The majority of studies (n = 45) were deemed to be of good quality. Narrative analysis showed that SMI led to increases in use of inpatient, emergency, and primary care services. Meta-analyses revealed that patients with SMI were more likely to be admitted as nonpsychiatric inpatients (pooled odds ratio [OR] = 1.84, 95% confidence interval [CI] 1.21-2.80, p = 0.005, I2 = 100%), had hospital stays that were increased by 0.59 days (pooled standardised mean difference = 0.59 days, 95% CI 0.36-0.83, p < 0.001, I2 = 100%), were more likely to be readmitted to hospital within 30 days (pooled OR = 1.37, 95% CI 1.28-1.47, p < 0.001, I2 = 83%), and were more likely to attend the emergency department (pooled OR = 1.97, 95% CI 1.41-2.76, p < 0.001, I2 = 99%) compared to patients without SMI. Study limitations include considerable heterogeneity across studies, meaning that results of meta-analyses should be interpreted with caution, and the fact that it was not always possible to determine whether service use outcomes definitively excluded mental health treatment. CONCLUSIONS In this study, we found that SMI impacts significantly upon the use of nonpsychiatric health services. Illustrating and quantifying this helps to build a case for and guide the delivery of system-wide integration of mental and physical health services.

Abstract
BACKGROUND The influence of schizophrenia on total knee arthroplasty (TKA) is limited in the literature. Therefore, the purpose of this study was to investigate whether patients with schizophrenia undergoing primary TKA have (1) longer in-hospital length of stay (LOS); (2) higher readmission rates; (3) higher medical complications; (4) higher implant-related complications; and (5) higher costs of care compared to controls. METHODS Patients with schizophrenia undergoing primary TKA were identified within the Medicare claims database. The study group was randomly matched in a 1:5 ratio to controls according to age, sex, and medical comorbidities. The query yielded 49,176 patients with (n = 8,196) and without (n = 40,980) schizophrenia undergoing primary TKA. Primary outcomes analyzed included in-hospital LOS, 90-day readmission rates, 90-day medical complications, 2-year implant-related complications, in addition to day of surgery and 90-day costs of care. A P-value less than .01 was considered statistically significant. RESULTS Schizophrenia patients had longer in-hospital LOS (3.73 days vs 3.22 days, P < .0001) and had higher incidence and odds ratios (ORs) of readmission rates (18.26 vs 12.07%; OR: 1.58, P < .0001) compared to controls. Schizophrenia patients had higher incidence and odds of medical (3.23 vs 1.10%; OR: 2.99, P < .0001) and implant-related complications (5.92 vs 3.59%; OR: 1.68, P < .0001) and incurred significantly higher day of surgery ($13,300.58 vs $11,681.77, P < .0001) and 90-day costs of care ($18,222.18 vs $14,845.64, P < .0001). CONCLUSION This study demonstrates that patients with schizophrenia have longer in-hospital LOS, higher readmission rates, higher complications, and increased costs of care after primary TKA.

Abstract
BACKGROUND A shift in the healthcare system towards the centralization of common yet costly surgeries, such as total hip arthroplasty (THA), to high-volume centers of excellence, is an attempt to control the economic burden while simultaneously enhancing patient outcomes. The "volume-outcome" relationship suggests that hospitals performing more treatment of a given type exhibit better outcomes than hospitals performing fewer. This theory has surfaced as an important factor in determining patient outcomes following THA. We performed a systematic review with meta-analyses to review the available evidence on the impact of hospital volume on outcomes of THA. MATERIALS AND METHODS We conducted a review of PubMed (MEDLINE), OVID MEDLINE, Google Scholar, and Cochrane library of studies reporting the impact of hospital volume on THA. The studies were evaluated as per the inclusion and exclusion criteria. A total of 44 studies were included in the review. We accessed pooled data using random-effect meta-analysis. RESULTS Results of the meta-analyses show that low-volume hospitals were associated with a higher rate of surgical site infections (1.25 [1.01, 1.55]), longer length of stay (RR, 0.83[0.48-1.18]), increased cost of surgery (3.44, [2.57, 4.30]), 90-day complications (RR, 1.80[1.50-2.17]) and 30-day (RR, 2.33[1.27-4.28]), 90-day (RR, 1.26[1.05-1.51]), and 1-year mortality rates (RR, 2.26[1.32-3.88]) when compared to high-volume hospitals following THA. Except for two prospective studies, all were retrospective observational studies. CONCLUSIONS These findings demonstrate superior outcomes following THA in high-volume hospitals. Together with the reduced cost of the surgical procedure, fewer complications may contribute to saving considerable opportunity costs annually. However, a need to define objective volume-thresholds with stronger evidence would be required. TRIAL REGISTRATION PROSPERO CRD42019123776.

Abstract
The second most common complication following total hip arthroplasty (THA) is dislocation. The majority of dislocations occur early in the post-operative period and are due to either patient-associated or surgical factors. The patient-associated factors that have been implicated as causes of post-operative dislocation include previous surgery, lumbar spine fusion surgery and/or neurological impairment. The surgical factors include surgical approach, component orientation and prosthetic and/or bony impingement. In order to delineate the cause of the hip instability a thorough history and physical and a radiographic assessment (possibly including advanced imaging) needs to be performed. Approximately two thirds of cases are successfully treated; one third of cases will require surgical treatment (e.g., revision arthroplasty (including constrained liners, the use of elevated rim liners and dual mobility implants or trochanteric advancement). In this review, we discuss the causes leading to dislocation following THA and evaluate the different treatment options available.

Should Medical Severity-Diagnosis Related Group Classification Be Utilized for Reimbursement? An Analysis of Elixhauser Comorbidities and Cost of Care. J Arthroplasty 2019; 34:1312-1316.

Abstract
BACKGROUND The Center for Medicare and Medicaid Services (CMS) classifies reimbursement for total hip arthroplasty (THA) and total knee arthroplasty (TKA) based on Medical Severity-Diagnosis Related Groups (MS-DRGs) 469 (with major complication/comorbidity) and 470 (without major complication/comorbidity). The validated Elixhauser comorbidity index includes 31 variables that may be associated with MS-DRG 469. However, we hypothesized that these comorbidities may not be the most predictive of increased cost of care. METHODS Elixhauser comorbidities were retrospectively examined for 1243 TKAs and 897 THAs from 2013 to 2017 at a single center. Comorbidities were investigated in univariable analysis and significant variables associated with MS-DRG 469, and cost of care was further investigated in a multivariable regression to determine which were most predictive of the increased complexity classification assigned by CMS vs true increased cost of care. RESULTS Thirty-nine patients (1.8%) were classified as MS-DRG 469. Univariable and multivariable logistic analysis revealed that coagulopathy, electrolyte disorders, neurodegenerative disorders, and psychosis were significantly associated with an increased complexity classification. These 4 comorbidities were also associated with increased cost of care; however, 13 additional comorbidities were also predictive of increased cost but not MS-DRG classification. CONCLUSIONS Patient comorbidities have been shown to increase complications and cost of care for arthroplasty patients. To date, however, the only risk adjustment provided has been the 469 DRG code. This study demonstrates little correlation to the current system with the most expensive diagnoses. Consequently, an expansion of the current risk adjustment system for THA and TKA provided by CMS appears greatly needed.

Abstract
BACKGROUND Surgeon volume has been identified as an important factor impacting postoperative outcome in patients undergoing orthopedic surgeries. With an absence of a detailed systematic review, we sought to collate evidence on the impact of surgeon volume on postoperative outcomes in patients undergoing primary total hip arthroplasty. METHODS PubMed (MEDLINE) and Google Scholar databases were queried for articles using the following search criteria: ("Surgeon Volume" OR "Provider Volume" OR "Volume Outcome") AND ("THA" OR "Total hip replacement" OR "THR" OR "Total hip arthroplasty"). Studies investigating total hip arthroplasty being performed for malignancy or hip fractures were excluded from the review. Twenty-eight studies were included in the final review. All studies underwent a quality appraisal using the GRADE tool. The systematic review was performed in accordance with the PRISMA guidelines. RESULTS Increasing surgeon volume was associated with a shorter length of stay, lower costs, and lower dislocation rates. Studies showed a significant association between an increasing surgeon volume and higher odds of early-term and midterm survivorship, but not long-term survivorships. Although complications were reported and recorded differently in studies, there was a general trend toward a lower postoperative morbidity with regard to complications following surgeries by a high-volume surgeon. CONCLUSION This systematic review shows evidence of a trend toward better postoperative outcomes with high-volume surgeons. Future prospective studies are needed to better determine long-term postoperative outcomes such as survivorship before healthcare policies such as regionalization and/or equal-access healthcare systems can be considered.
