Abstract
STUDY DESIGN This was a retrospective cohort studying using a national administrative database. OBJECTIVE The objective of this study was to determine the postoperative complications and quality outcomes of the human immunodeficiency virus (HIV)-positive patients undergoing surgical management for lumbar degenerative disease (LDD). METHODS This study identified patients with who underwent surgery for LDD between 2007 and 2016. Patients were stratified based on whether they were HIV positive at the time of surgery. Multivariate regression was utilized to reduce the confounding of baseline covariates. Patients who underwent 3 or more levels of surgical correction were under the age of 18 years, or those with any prior history of trauma or tumor were excluded from this study. Baseline comorbidities, postoperative complication rates, and reoperation rates were determined. RESULTS A total of 120,167 patients underwent primary lumbar degenerative surgery, of which 309 (0.26%) were HIV positive. In multivariate regression analysis, the HIV-positive cohort was more likely to be readmitted at 30 days [odds ratio (OR)=1.9, 95% confidence interval (CI): 1.2-2.8], 60 days (OR=1.7, 95% CI: 1.2-2.5), and 90 days (OR=1.5, 95% CI: 1.0-2.2). The HIV-positive cohort was also more likely to experience any postoperative complication (OR=1.7, 95% CI: 1.2-2.3). Of the major drivers identified, HIV-positive patients had significantly greater odds of cerebrovascular disease and postoperative neurological complications (OR=3.8, 95% CI: 1.8-6.9) and acute kidney injury (OR=3.4, 95% CI: 1.3-7.1). Costs of index hospitalization were not significantly different between the 2 cohorts ($30,056 vs. $29,720, P=0.6853). The total costs were also similar throughout the 2-year follow-up period. CONCLUSION Patients who are HIV positive at the time of LDD surgery are at a higher risk for postoperative central nervous system and renal complications and unplanned readmissions.

Impact of human immunodeficiency virus on 2-year revision rates following lumbar fusion for degenerative spinal conditions: a retrospective cohort study. JOURNAL OF SPINE SURGERY (HONG KONG) 2021; 7:475-484. [PMID: 35128121 PMCID: PMC8743293 DOI: 10.21037/jss-21-84] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/16/2021] [Accepted: 10/13/2021] [Indexed: 06/14/2023]
Abstract
BACKGROUND To our knowledge, no studies exist that evaluate the impact of human immunodeficiency virus (HIV) on long-term revision rates following lumbar fusion. This study aims to understand how HIV impacts 2-year revision rates and 90-day postoperative complication rates following primary lumbar fusion for degenerative spine conditions. METHODS Data collection was done using PearlDiver Patient Records Database, a national insurance database from 2010-2019. Patients who underwent primary lumbar fusion for degenerative diseases were divided into a cohort of patients that are HIV positive (HIV), have asymptomatic HIV (AHIV), acquired immune deficiency syndrome (AIDS), and HIV-negative at the time of their procedure. Univariate and multivariable regression analyses were performed to determine rates of revision surgery, surgical site infection (SSI), neurological complications, sensory deficits, bowel/bladder dysfunction and myelopathies within two years of surgery as well as 90-day postoperative complications. RESULTS In total, 216,587 patients were included in this study. Of these, 631 patients (0.29%) had HIV including 502 patients (0.23%) with asymptomatic HIV and 129 patients (0.06%) with AIDS. Relative to the control cohort, patients with HIV had no difference in odds of two-year revision surgery, SSI, neurological complications, sensory deficits, bowel/bladder dysfunction and myelopathies. Patients with HIV did have increased odds of postoperative pneumonia (OR 1.592; 95% CI: 1.048-2.314; P=0.021). AIDS patients had greater odds of respiratory complications (OR 2.585; 95% CI: 1.075-5.264; P=0.017) and septic complications (OR 2.702; 95% CI: 1.122-5.514; P=0.013) 90-day postoperatively. CONCLUSIONS Our study found that HIV positive status did not significantly affect two-year revision rates compared to the control group. However, there is a higher rate of pneumonia and respiratory complications among HIV positive patients. Before deciding to proceed with surgical intervention in HIV positive individuals, surgeons must carefully consider each patient's specific diagnosis, comorbidities, and risk factors.

Abstract
BACKGROUND AND STUDY AIMS The objective of this review is to evaluate the incidence of operative treatment, outcomes, and complications of surgery for degenerative spine disease (DSD) on human immunodeficiency virus (HIV) positive patients. Combined antiretroviral treatment led HIV patients to live long enough to develop many chronic conditions common in the uninfected population. Surgery for DSD is one of the most commonly performed neurosurgical procedures. However, the incidence of spine surgery for DSD in HIV-positive patients seems to be lower than that in uninfected individuals, although this has not been clearly determined. METHODS A systematic search of the Medline, Web of Science, Embase, and SciElo databases was conducted. Only primary studies addressing DSD surgery on HIV-positive patients were included. Evaluated variables were rates of surgical treatment, surgical outcomes and complications, year of publication, country where study was conducted, type of study, and level of evidence. RESULTS Six articles were included in the review from 1,108 records. Significantly lower rates of DSD surgery were identified in HIV-infected patients (0.86 per 1,000 patient-years) when compared with uninfected patients (1.41 per 1,000 patient-years). There was a significant increase in spinal surgery in HIV-positive patients over time, with a 0.094 incidence per 100,000 in the year 2000 and 0.303 in 2009. HIV-positive patients had very similar outcomes when compared with controls, with 66.6% presenting pain relief at a 3-month follow-up. Higher incidences of hospital mortality (1.6 vs. 0.3%; p < 0.001) and complications (12.2 vs. 9.5%, p < 0.001) were observed in HIV carriers. CONCLUSIONS HIV-positive individuals appear to undergo less surgery for DSD than HIV-negative individuals. Improvement rates appear to be similar in both groups, even though some complications appear to be more prevalent in HIV carriers. Larger studies are needed for decisive evidence on the subject.

Inpatient Outcomes After Elective Lumbar Spinal Fusion for Patients with Human Immunodeficiency Virus in the Absence of Acquired Immunodeficiency Syndrome. World Neurosurg 2018; 116:e913-e920. [PMID: 29852306 DOI: 10.1016/j.wneu.2018.05.128] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2018] [Revised: 05/18/2018] [Accepted: 05/18/2018] [Indexed: 10/14/2022]
Abstract
BACKGROUND To our knowledge, no prior study has evaluated outcomes after elective lumbar spinal surgery in human immunodeficiency virus (HIV) patients without acquired immunodeficiency syndrome (AIDS). This review investigated the impact of HIV-positive status (without AIDS) on outcomes after elective lumbar fusion for degenerative disc disease (DDD). METHODS Adult patients registered in the Nationwide Inpatient Sample (2002-2011) undergoing elective lumbar fusion for DDD were extracted. Multivariable regression techniques were used to explore the association of HIV positivity with outcomes after lumbar fusion. RESULTS This cohort included 612,000 hospitalizations (0.07% were HIV positive) of lumbar fusion for DDD. Compared with HIV-negative patients undergoing lumbar fusion, HIV-positive patients were younger (47 vs. 55 years), male (61% vs. 42%), largely insured by Medicare (30% vs. 5%), and had higher rates of chronic obstructive pulmonary disease (23.7% vs. 14.6%) (all P < 0.001) but had lower rates of obesity, hypertension, and diabetes (all P < 0.001). Multivariable models demonstrated HIV positivity to be associated with higher odds for an adverse event (odds ratio [OR], 1.92; P < 0.001), in-hospital mortality (OR, 39.91; P < 0.001), wound complications (OR, 2.60; P = 0.004), respiratory (OR, 5.43; P < 0.001) and neurologic (OR, 1.96; P = 0.039) complications, and higher costs (7.1% higher; P = 0.011) compared with non-HIV patients. There were no differences in thromboembolic events, cardiac or gastrointestinal complications, discharge disposition, or length of stay. CONCLUSIONS Even in this selected cohort of well-controlled HIV patients, there were high complications, with concerning rates of death and respiratory complications. These data shed new light on elective spine surgery in HIV patients and may influence the treatment algorithm of surgeons who are familiar with older papers.

Abstract
BACKGROUND Individuals coinfected with both hepatitis C virus (HCV) and HIV represent a unique and growing population of patients undergoing orthopaedic surgical procedures. Data regarding complications for HCV monoinfection or HIV monoinfection are robust, but there are no data available, to our knowledge, on patients who have both HCV and HIV infections. QUESTIONS/PURPOSES We sought to determine whether patients with coinfection differed in terms of baseline demographics and comorbidity burden as compared with patients without coinfection and whether these potential differences were translated into varying levels of postoperative complications, mortality, and hospital readmission risk. Specifically, we asked: (1) Are there demonstrable differences in baseline demographic variables between patients infected with HCV and HIV and those who do not have those infections (age, sex, race, and insurance status)? (2) Do patients with HCV and HIV infection differ from patients without those infections in terms of other medical comorbidities? (3) Do patients with HCV/HIV coinfection have a higher incidence of early postoperative complications and mortality than patients without coinfection? (4) Is the frequency of readmission greater for patients with HCV/HIV coinfection than those without? METHODS The New York Statewide Planning and Research Cooperative System (SPARCS) database was used to identify patients undergoing THA between 2010 and 2014. The SPARCS database is particularly useful because it captures 100% of all New York State inpatient admissions while providing detailed demographic and comorbidity data for a large, heterogeneous patient population with long-term followup. Patients were stratified into four groups based on HCV/HIV status: control patients without disease, HCV monoinfection, HIV monoinfection, and coinfection. We sought to determine whether patients coinfected with HCV and HIV would differ in terms of demographics from patients without those infections and whether patients with HCV and HIV would have a greater risk of complications, longer length of stay, and hospital readmission. A total of 80,722 patients underwent THA between 2010 and 2014. A total of 98.55% (79,554 of 80,722) of patients did not have either HCV or HIV, 0.66% (530 of 80,722) had HCV monoinfection, 0.66% (534 of 80,722) HIV monoinfection, and 0.13% (104 of 80,722) were coinfected with both HCV and HIV. Multivariate analysis was performed controlling for age, sex, insurance, residency status, diagnosis, and comorbidities to allow for an equal comparison between groups. RESULTS Patients with coinfection were more likely to be younger, male (odds ratio [OR], 2.90; 95% confidence interval [CI], 2.20-3.13; p < 0.001), insured by Medicaid (OR, 6.43; 4.41-7.55; p < 0.001), have a history of avascular necrosis (OR, 8.76; 7.20-9.53; p < 0.001), and to be homeless (OR, 6.95; 5.31-7.28; p < 0.001) as compared with patients without HIV or HCV. Additionally, patients with coinfection had the highest proportion of alcohol abuse, drug abuse, and tobacco use along with a high proportion of psychiatric disorders, including depression. HCV and HIV coinfection were independent risk factors for increased length of stay (OR, 1.97; 95% CI, 1.29-3.01; p < 0.001), having two or more in-hospital complications (OR, 1.64; 1.01-2.67; p < 0.001), and 90-day readmission rates (OR, 2.97; 1.86-4.77; p < 0.001). CONCLUSIONS As the prevalence of HCV and HIV coinfectivity continues to increase, orthopaedic surgeons will encounter a greater number of these patients. Awareness of the demographic and socioeconomic factors leading to increased complications after THA will allow physicians to consider interventions such as in-hospital psychiatric counseling, advanced discharge planning, and coordination with social work and collaboration with HCV/HIV infectious disease specialists to improve patient health status to improve outcomes and reduce costs. LEVEL OF EVIDENCE Level III, therapeutic study.

Abstract
Background As medical management continues to improve, orthopaedic surgeons are likely to encounter a greater proportion of patients who have coinfection with human immunodeficiency virus (HIV) and hepatitis-C virus (HCV). Methods The New York Statewide Planning and Research Cooperative System (SPARCS) database was used to identify patients undergoing total knee arthroplasty between 2010 and 2014. Patients were stratified into 4 groups on the basis of HCV and HIV status. Differences regarding baseline demographics, length of stay, total charges, discharge disposition, in-hospital complications and mortality, and 90-day hospital readmission were calculated. Results Between 2010 and 2014, a total of 137,801 patients underwent total knee arthroplasty. Of those, 99.13% (136,604) of the population were not infected, 0.62% (851) had HCV monoinfection, 0.20% (278) had HIV monoinfection, and 0.05% (68) were coinfected with both HCV and HIV. Coinfected patients were more likely to be younger, female, a member of a minority group, homeless, and insured by Medicare or Medicaid, and to have a history of substance abuse. HCV and HIV coinfection was a significant independent risk factor for increased length of hospital stay (odds ratio [OR], 2.9; 95% confidence interval [CI], 1.75 to 4.81), total hospital charges in the 90th percentile (OR, 2.02; 95% CI, 1.12 to 3.67), ≥2 in-hospital complications (OR, 2.04; 95% CI, 1.04 to 3.97), and 90-day hospital readmission (OR, 3.53; 95% CI, 2.02 to 6.18). Conclusions Patients coinfected with both HCV and HIV represent a rare but increasing population of individuals undergoing total knee arthroplasty. Recognition of unique baseline demographics in these patients that may lead to suboptimal outcomes will allow appropriate preoperative management and multidisciplinary coordination to reduce morbidity and mortality while containing costs. Level of Evidence Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Appendectomy in patients with human immunodeficiency virus: Not as bad as we once thought. Surgery 2016; 161:1076-1082. [PMID: 27884613 DOI: 10.1016/j.surg.2016.09.035] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2016] [Revised: 08/28/2016] [Accepted: 09/28/2016] [Indexed: 01/12/2023]
Abstract
BACKGROUND The number of patients living with human immunodeficiency virus and acquired immunodeficiency syndrome is growing due to advances in antiretroviral therapy. Existing literature on appendectomy within this patient population has been limited by small sample sizes. Therefore, we used a large, multiyear, nationwide database to study this topic comprehensively. METHODS Using the Nationwide Inpatient Sample, we identified 338,805 patients between 2005 and 2012 who underwent laparoscopic or open appendectomy for acute appendicitis. Interval appendectomies were excluded. We used multivariable adjusted regression models to test differences between patients with human immunodeficiency virus without acquired immunodeficiency syndrome and a reference group, as well as human immunodeficiency virus with acquired immunodeficiency syndrome and a reference group, with regard to duration of stay, hospital charges, in-hospital complications, and in-hospital mortality. Models were adjusted for patient age, sex, race, insurance, socioeconomic status, Elixhauser comorbidity score, and appendix perforation. RESULTS There were 1,291 (0.38%) patients with human immunodeficiency virus, among which 497 (0.15%) patients had acquired immunodeficiency syndrome. In regression analysis, human immunodeficiency virus alone was not associated with adverse outcomes, while acquired immunodeficiency syndrome alone was associated with longer duration of stay (incidence rate ratio 1.40 [1.37-1.57 95% confidence interval], P < .0001), increased total charges (exponentiated coefficient 1.16 [1.10-1.23 95% confidence interval], P < .0001), and increased risk of postoperative infection (odds ratio 2.12 [1.44-3.13 95% confidence interval], P = .0002). CONCLUSION Patients with acquired immunodeficiency syndrome who undergo appendectomy for acute appendicitis are subject to longer and more expensive hospital admissions and have greater rates of postoperative infections while patients with human immunodeficiency virus alone are not at risk for adverse outcomes.
