Sun J, Yang G, Yang C. Influence of postoperative hypoalbuminemia and human serum albumin supplementation on incision healing following total knee arthroplasty for knee osteoarthritis: a retrospective study. Sci Rep 2024; 14:17354. [PMID: 39075140 PMCID: PMC11286832 DOI: 10.1038/s41598-024-68482-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2024] [Accepted: 07/24/2024] [Indexed: 07/31/2024] Open
Abstract
With distinct advantages in clinical application, total knee arthroplasty (TKA) is an effective surgical option for treating end-stage osteoarthritis in the knee. After TKA, incisional problems are one of the major factors influencing the speed in which patients recover. Although it is widely acknowledged that preoperative hypoalbuminemia and the incidence of incisional complications are significantly associated, it is still unclear if postoperative hypoalbuminemia raises the risk of incisional complications following TKA. Furthermore, human serum albumin (HSA) is frequently utilized domestically and internationally to treat postoperative hypoalbuminemia; nevertheless, there is ongoing discussion on whether HSA supplementation can enhance postoperative clinical outcomes. To investigate the relationship between hypoalbuminemia and suboptimal incision healing following TKA, as well as to determine whether HSA supplementation can enhance incision healing after surgery, we collected clinical data for this study. The study sample consisted of 22 patients with poorly healed incisions and 120 cases with normal healing of incisions who underwent TKA treatment for knee osteoarthritis (KOA) in the operator's hospital's Department of Orthopaedics between July 1, 2020, and July 1, 2023. To determine the prevalence of postoperative poor incision healing, data on patients' basic characteristics, preoperative test results, surgical data, postoperative test results, and postoperative incision healing were gathered. The contributing factors to inadequate recovery after surgery were examined using SPSS software. After controlling for confounding variables, a multivariate regression analysis model was used to examine the relationship between postoperative hypoalbuminemia, HSA supplementation, and poor incision healing. 22 cases (15.49%) had poor wound healing following surgery. The findings of multivariate regression analysis after controlling for confounders indicated that there was no correlation between poor wound healing and postoperative albumin level (P > 0.05). Similarly, there was no association (P > 0.05) seen between HSA supplementation and poor incision healing. Following the TKA, postoperative hypoalbuminemia does not raise the risk of incisional problems, and postoperative HSA supplementation neither lowers nor enhances the risk of inadequate incisional healing.

World Neurosurg 2024:S1878-8750(24)00988-4. [PMID: 38871286 DOI: 10.1016/j.wneu.2024.06.030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2024] [Accepted: 06/07/2024] [Indexed: 06/15/2024]
Abstract
BACKGROUND Malnutrition frequently is associated with increased complications and worse outcomes after surgery. The purpose of this study was to determine whether malnutrition status determined using the Geriatric Nutritional Risk Index (GNRI) can serve as an independent risk factor for complications in patients undergoing anterior cervical discectomy and fusion (ACDF). METHODS The American College of Surgeons National Surgical Quality Improvement Program database was queried from 2011 to 2016 for patients age ≥65 years who underwent ACDF. Patients were categorized into 3 groups based on the GNRI: >98, normal nutritional status; 92-98, moderately malnourished; and <92, severely malnourished. Multivariate logistic regression models adjusted for covariates of demographics, comorbidities, and operative metrics were used to evaluate GNRI as an independent risk factor for postoperative outcomes. RESULTS A total of 3148 patients who underwent ACDF were analyzed, of whom 78.9% had normal nutrition, 16.1% were moderately malnourished, and 5.0% patients were severely malnourished. On multivariate analysis, moderate and severe malnutrition were found to be independent risk factors for any complication, pulmonary complications, pneumonia, unplanned intubation, and hospital length of stay >6 days (P < 0.05 for all). In addition, moderate malnutrition was a risk factor for failure to wean from ventilation for >48 hours and 30-day readmission. Severe malnutrition was an independent risk factor for septic shock and nonhome discharge. CONCLUSIONS In elderly patients after ACDF, malnutrition determined using GNRI is an independent risk factor for 30-day complications, readmissions, prolonged hospital length of stay, and nonhome discharge.

CNS Neurosci Ther 2024; 30:e14343. [PMID: 37408469 PMCID: PMC10848042 DOI: 10.1111/cns.14343] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2022] [Revised: 05/07/2023] [Accepted: 06/24/2023] [Indexed: 07/07/2023] Open
Abstract
AIMS The aims of the study were to determine the relationship between preoperative geriatric nutritional risk index (GNRI) and the occurrence of postoperative delirium (POD) in elderly patients after cardiac surgery and to evaluate the additive value of GNRI for predicting POD. METHODS The data were extracted from the Multiparameter Intelligent Monitoring in Intensive Care (MIMIC-IV) database. Patients who underwent cardiac surgery and were aged 65 or older were included. The relationship between preoperative GNRI and POD was investigated using logistic regression. We determined the added predictive value of preoperative GNRI for POD by measuring the changes in the area under the receiver operating characteristic curve (AUC) and calculating the net reclassification improvement (NRI) and integrated discrimination improvement (IDI). RESULTS A total of 4286 patients were included in the study, and 659 (16.1%) developed POD. Patients with POD had significantly lower GNRI scores than patients without POD (median 111.1 vs. 113.4, p < 0.001). Malnourished patients (GNRI ≤ 98) had a significantly higher risk of POD (odds ratio, 1.83, 90% CI, 1.42-2.34, p < 0.001) than those without malnutrition (GNRI > 98). This correlation remains after adjusting for confounding variables. The addition of GNRI to the multivariable models slightly but not significantly increases the AUCs (all p > 0.05). Incorporating GNRI increases NRIs in some models and IDIs in all models (all p < 0.05). CONCLUSIONS Our results showed a negative association between preoperative GNRI and POD in elderly patients undergoing cardiac surgery. The addition of GNRI to POD prediction models may improve their predictive accuracy. However, these findings were based on a single-center cohort and will need to be validated in future studies involving multiple centers.

Abstract
➤ Malnutrition is common among subsets of patients undergoing orthopaedic surgery and is associated with an increased risk of postoperative complications.➤ Serum proteins, in particular, albumin, may be used in the evaluation of nutritional status.➤ Anthropometric measurements and surveys also play a role in the evaluation of nutritional status.➤ Increased energy and nutrient requirements due to surgical procedures necessitate increased caloric and protein intake in the perioperative period, which may be achieved through diet or supplementation.➤ Evidence supports the use of protein-calorie, amino acid, and immunonutrition supplements. Vitamin D supplementation is an area of further consideration.➤ Diet restriction, activity alterations, pharmacotherapy, and bariatric surgery are all safe, effective approaches to weight loss, although the optimal timing and magnitude of preoperative weight loss require further investigation.

Abstract
A surgical site infection (SSI) is one of the most common complications of spinal surgery. Malnutrition has also been linked to SSI after other surgical procedures. However, whether malnutrition is a risk factor for SSI after spinal surgery remains controversial. Therefore, we performed a meta-analysis to comprehensively evaluate the relationship between malnutrition and SSI. Relevant studies of the correlation between malnutrition and SSI were retrieved from the Cochrane Library, EMBASE, PubMed, Web of Science, China National Knowledge Infrastructure and Wanfang Data from database inception to 21 May 2023. Two reviewers independently assessed the included studies, and a meta-analysis was performed using STATA 17.0 software. A total of 24 articles with 179 388 patients were included: 3919 and 175 469 cases comprised the SSI and control groups, respectively. The meta-analysis results showed that malnutrition significantly increased the SSI incidence (odds ratio, 1.811; 95% confidence interval, 1.512-2.111; p < 0.001). These results suggest that patients with malnutrition are at higher risk for SSI after surgery. However, because of significant differences in sample sizes among studies, and because some studies had limitations to their methodological quality, further validation of these results by additional high-quality studies with larger sample sizes is necessary.

Abstract
BACKGROUND Surgical site infection is one of the serious complications of transforaminal lumbar interbody fusion surgery, and many factors affect its occurrence. METHODS A total of 1,277 patients who underwent transforaminal lumbar interbody fusion between 2018 and 2021 were enrolled in this study. Subsequently, 1,277 patients were randomly assigned to a training cohort (N = 958) and a validation cohort (N = 319) in a 3:1 ratio. We developed a nomogram according to the results of binary logistic regression analysis in the training cohort. The nomogram's predictive accuracy and discriminative ability were evaluated by calibration curve and receiver operating characteristic analysis. Decision curve analysis was performed to estimate the clinical value of our nomogram. RESULTS In univariate and multivariate analysis, smoking, diabetes, intraoperative blood loss, American Society of Anesthesiologists class ≥III, serum calcium, albumin, and serum glucose were identified as significant independent predictors. The nomogram was developed using these independent predictors, which showed good diagnostic accuracy for surgical site infection of the training and validation cohorts. The calibration curves for the 2 cohorts showed optimal agreement between nomogram prediction and actual observation. The decision curve analysis of the nomogram model showed the great clinical use of the nomogram. CONCLUSION The nomogram based on smoking, diabetes, intraoperative blood loss, American Society of Anesthesiologists class, serum calcium, albumin, and serum glucose has the potential as a clinically useful predictive tool of surgical site infection after transforaminal lumbar interbody fusion surgery. It is helpful to visualize the risk factors of surgical site infection.

Abstract
PURPOSE This study aimed to evaluate the correlation between hypoalbuminemia upon admission and the incidence of postoperative urinary tract infections (UTIs) in elderly patients with hip fractures. METHODS A retrospective analysis was performed on the medical records of elderly patients who underwent surgical treatment for hip fractures at a level I trauma center from 2013 to 2023. Serum albumin levels were measured upon admission, and hypoalbuminemia was defined as a total albumin level < 35 g/L. Multivariable logistic regression and propensity score matching analysis were utilized to control and reduce potential confounding factors, aiming to obtain adjusted odds ratios (ORs) and 95% confidence intervals (CI) for UTIs to determine the strength of the association. RESULTS This observational cohort study included 1279 patients, among whom 298 (23.3%) developed UTIs. Patients with albumin levels < 35 g/L had significantly greater odds of developing UTIs compared to those with albumin levels ≥ 35 g/L (OR 1.86, 95% CI 1.28-2.70). Further analysis, dividing albumin levels into quartiles, demonstrated that patients in the Q2 group (38.0-40.9 g/L; OR 1.38, 95% CI 0.88-2.17), Q3 group (35.0-37.9 g/L; OR 1.69, 95% CI 1.06-2.71), and Q4 group (15.3-34.9 g/L; OR 2.67, 95% CI 1.61-4.43) had notably higher odds of developing UTIs compared to those in the Q1 group (41.0-52.0 g/L). CONCLUSIONS The presence of hypoalbuminemia upon admission in elderly patients undergoing hip fracture surgery is strongly correlated with the occurrence of postoperative UTIs. Furthermore, this association exhibits a clear dose-response relationship.

Association of preoperative hypoprotein malnutrition with spinal postoperative complications and other conditions: A systematic review and meta-analysis. Clin Nutr ESPEN 2023; 57:448-458. [PMID: 37739691 DOI: 10.1016/j.clnesp.2023.07.083] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2023] [Revised: 07/14/2023] [Accepted: 07/17/2023] [Indexed: 09/24/2023]
Abstract
BACKGROUND Postoperative complications of spinal surgery are a common clinical problem, which impose significant economic and clinical burdens on patients and medical staff. Previous studies have suggested a close relationship between low-protein malnutrition and postoperative complications of surgery. However, the relationship between preoperative malnutrition and various orthopedic postoperative complications remains unclear. PURPOSE To investigate the association between protein malnutrition and postoperative complications and outcomes. METHODS We conducted a systematic search of the PubMed, Embase, Cochrane Library, and Web of Science databases for published research articles between the database inception and February 28th, 2023, that evaluated the association between malnutrition and the risk of postoperative complications and death in spinal surgery patients. Malnutrition was defined as low pre-albumin and albumin levels before surgery. Two evaluators independently extracted study data and assessed the risk of bias in each study. Fixed- or random-effect models were used to calculate the pooled effect estimates. Funnel plots and Egger's tests were used to detect publication bias, and the Trim-and -Fill method was conducted to evaluate the impact of publication bias on the results. RESULTS A total of 26 studies were included in this meta-analysis, comprising 17 retrospective cohort studies and 9 case-control studies. The study included more than 86,000 participants. Analysis of postoperative complications revealed that the overall incidence of malnutrition-related complications after surgery was 3.17 times higher (OR = 3.17, 95% CI 2.69-3.75, z = 13.57, P < 0.05). The incidence of surgical site infections was 2.08 times higher (OR = 2.08, 95% CI 1.66-2.62, z = 6.307, P < 0.05), and the incidence of postoperative urinary tract infections was 2.55 times higher (OR = 2.55, 95% CI 1.80-3.60, z = 5.30, P < 0.05). The incidence of postoperative sepsis was 3.31 times higher (OR = 3.31, 95% CI 2.31-4.75, z = 6.51, P < 0.05), and the incidence of postoperative pneumonia was 3.02 times higher (OR = 3.02, 95% CI 1.331-6.857, z = 2.64, P = 0.008 < 0.05). The incidence of postoperative cardiac complications was 4.24 times higher (OR = 4.24, 95% CI 2.45-7.35, z = 5.15, P < 0.05), and the incidence of postoperative renal complications was 4.04 times higher (OR = 4.04, 95% CI 2.06-7.93, z = 4.05, P < 0.05). The incidence of postoperative pulmonary complications was 2.38 times higher (OR = 2.38, 95% CI 1.46-3.87, z = 6.98, P < 0.05), while the incidence of postoperative thrombotic complications was 2.76 times higher (OR = 2.76, 95% CI 1.756-4.345, z = 4.40, P < 0.05). Furthermore, the incidence of transfusion during and after surgery was 1.33 times higher (OR = 1.33, 95% CI 1.13-1.56, z = 3.40, P = 0.001 < 0.05), the incidence of postoperative readmission was 1.67 times higher (OR = 1.67, 95% CI 1.24-2.27, z = 3.33, P = 0.001 < 0.05), and the risk of postoperative death was 6.01 times higher (OR = 6.01, 95% CI 4.51-8.01, z = 12.27, P < 0.05). After conducting a publication bias test and Trim-and -Fill method analysis, we found no evidence of publication bias, and the results remained stable. CONCLUSION Preoperative low protein malnutrition is closely related to the incidence of postoperative complications and postoperative status. More prospective multicenter studies should be conducted to validate this conclusion. Furthermore, more effective assessment and intervention of preoperative nutritional status should be carried out to prevent the occurrence of postoperative complications and mortality risk.

Abstract
To analyse the clinical data of patients who developed incisional complications and those who did not develop incisional complications after lumbar internal fixation, and investigate the risk factors for incisional complications in patients after lumbar internal fixation with posterior midline incision. A standardised data collection form was used to collect the clinical data of patients who were admitted and underwent lumbar internal fixation in our hospital from July 2018 to July 2021. Patients who experienced any one of the incisional complications, such as incision exudates, swelling, blisters, bruising, superficial/deep incisional infections, poor healing and scarring, after surgery were included in the incisional complication group, and patients who did not develop the above-mentioned incisional complications were included in the control group. Univariate logistic regression analysis was first performed to identify potential risk factors, significant factors from univariate analysis were then included in multivariable logistic regression analysis to identify independent risk factors for incisional complications after lumbar spine surgery. Among 455 patients included in the study, postoperative incision complications occurred in 82 patients, with an incidence rate of 18.02%. Multivariate regression analysis identified seven independent risk factors for incisional complications: age, body mass index, preoperative albumin level, hypertension, diabetes mellitus, operation time and local anaesthetic infiltration at the incision site after surgery. Our findings documented that age, body mass index, preoperative albumin level, hypertension, diabetes mellitus, operation time, and postoperative local anaesthetic infiltration at the incision site were risk factors for incisional complications after lumbar internal fixation with posterior median incision. Awareness of these risk factors can enable surgeons to develop a more appropriate perioperative management plan for patients undergoing lumbar internal fixation, thus helping them recover faster.

Abstract
Objective The objective of this study was to utilize machine learning techniques to analyze perioperative factors and identify blood glucose levels that can predict the occurrence of surgical site infection following posterior lumbar spinal surgery. Methods A total of 4019 patients receiving lumbar internal fixation surgery from an institute were enrolled between June 2012 and February 2021. First, the filtered data were randomized into the test and verification groups. Second, in the test group, specific variables were screened using logistic regression analysis, Lasso regression analysis, support vector machine, and random forest. Specific variables obtained using the four methods were intersected, and a dynamic model was constructed. ROC and calibration curves were constructed to assess model performance. Finally, internal model performance was verified in the verification group using ROC and calibration curves. Results The data from 4019 patients were collected. In total, 1327 eligible cases were selected. By combining logistic regression analysis with three machine learning algorithms, this study identified four predictors associated with SSI, namely Modic changes, sebum thickness, hemoglobin, and glucose. Using this information, a prediction model was developed and visually represented. Then, we constructed ROC and calibration curves using the test group; the area under the ROC curve was 0.988. Further, calibration curve analysis revealed favorable consistency of nomogram-predicted values compared with real measurements. The C-index of our model was 0.986 (95% CI 0.981-0.994). Finally, we used the validation group to validate the model internally; the AUC was 0.987. Calibration curve analysis revealed favorable consistency of nomogram-predicted values compared with real measurements. The C-index was 0.982 (95% CI 0.974-0.999). Conclusion Logistic regression analysis and machine learning were employed to select four risk factors: Modic changes, sebum thickness, hemoglobin, and glucose. Then, a dynamic prediction model was constructed to help clinicians simplify the monitoring and prevention of SSI.

Int J Surg 2023; 109:2276-2285. [PMID: 37204435 PMCID: PMC10442129 DOI: 10.1097/js9.0000000000000461] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2023] [Accepted: 05/01/2023] [Indexed: 05/20/2023]
Abstract
BACKGROUND To develop a practical prediction model to predict the risk of deep surgical site infection (SSI) in patients receiving open posterior instrumented thoracolumbar surgery. METHODS Data of 3419 patients in four hospitals from 1 January 2012 to 30 December 2021 were evaluated. The authors used clinical knowledge-driven, data-driven, and decision tree model to identify predictive variables of deep SSI. Forty-three candidate variables were collected, including 5 demographics, 29 preoperative, 5 intraoperative, and 4 postoperative variables. According to model performance and clinical practicability, the best model was chosen to develop a risk score. Internal validation was performed by using bootstrapping methods. RESULTS After open posterior instrumented thoracolumbar surgery, 158 patients (4.6%) developed deep SSI. The clinical knowledge-driven model yielded 12 predictors of deep SSI, while the data-driven and decision tree model produced 11 and 6 predictors, respectively. A knowledge-driven model, which had the best C-statistics [0.81 (95% CI: 0.78-0.85)] and superior calibration, was chosen due to its favorable model performance and clinical practicality. Moreover, 12 variables were identified in the clinical knowledge-driven model, including age, BMI, diabetes, steroid use, albumin, duration of operation, blood loss, instrumented segments, powdered vancomycin administration, duration of drainage, postoperative cerebrospinal fluid leakage, and early postoperative activities. In bootstrap internal validation, the knowledge-driven model still showed optimal C-statistics (0.79, 95% CI: 0.75-0.83) and calibration. Based on these identified predictors, a risk score for deep SSI incidence was created: the A-DOUBLE-SSI (Age, D [Diabetes, Drainage], O [duration of Operation, vancOmycin], albUmin, B [BMI, Blood loss], cerebrospinal fluid Leakage, Early activities, Steroid use, and Segmental Instrumentation) risk score. Based on the A-DOUBLE-SSI score system, the incidence of deep SSI increased in a graded fashion from 1.06% (A-DOUBLE-SSIs score ≤8) to 40.6% (A-DOUBLE-SSIs score>15). CONCLUSIONS The authors developed a novel and practical model, the A-DOUBLE-SSIs risk score, that integrated easily accessible demographics, preoperative, intraoperative, and postoperative variables and could be used to predict individual risk of deep SSI in patients receiving open posterior instrumented thoracolumbar surgery.

EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2023; 32:2012-2019. [PMID: 37027034 DOI: 10.1007/s00586-023-07682-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/07/2022] [Revised: 02/14/2023] [Accepted: 03/22/2023] [Indexed: 04/08/2023]
Abstract
PURPOSE In this study, we intended to investigate the association between immediate postoperative hypoalbuminemia and surgical site infection (SSI), and determine a threshold value for postoperative hypoalbuminemia that can assist in risk stratification in patients after posterior lumbar fusion surgery. METHODS From January 2017 to December 2021, 466 consecutive patients who underwent posterior lumbar fusion surgery were selected to analyze the relationship between immediate postoperative hypoalbuminemia and SSI. Multivariate logistic regression analysis was performed to identify the independent risk factors of SSI and postoperative hypoalbuminemia. Receiver Operating Characteristic (ROC) analysis was used to determine the optimal value for postoperative hypoalbuminemia, and subsequent grouping was based on the identified threshold. RESULTS Of the total 466 patients, 25 patients (5.4%) developed SSI after surgery, and lower postoperative albumin (OR: 0.716, 95% CI: 0.611-0.840, p < 0.001) was independently associated with SSI. ROC analysis showed that the cutoff value of postoperative hypoalbuminemia was 32 g/L with a sensitivity of 0.760, specificity of 0.844, and a Youden index of 0.604. Postoperative SSI was more common in patients with postoperative hypoalbuminemia than in those without (21.6% vs. 1.6%, p < 0.001). Age, gender and operative duration were found to be independent predictors of postoperative hypoalbuminemia. CONCLUSIONS This study showed that immediate postoperative hypoalbuminemia was an independent risk factor for the development of SSI in patients who underwent posterior lumbar fusion. Even in patients with a normal preoperative serum albumin level, there was an increased risk of SSI when the postoperative albumin within 24 h was < 32 g/L.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVES The impact of modifiable risk factors (MRFs) on complications, costs, and readmission rates at 30, 90, and 180-days following lumbar spine fusion. METHODS Patients with lumbar spine fusions within the 2016-2017 Nationwide Readmissions Database (NRD). Patients were stratified by the following MRFs: Alcohol use, tobacco/nicotine use, nutritional malnourishment, dyslipidemia, and primary hypertension. Differences in complications, non-elective readmission rates, costs, and length of stay were compared between MRFs and the non-MRF group. Statistical analysis was conducted using Tukey multiple comparisons of means, 1-way ANOVA, Wald testing, unpaired Welch 2-sample t-tests, multivariate analysis, and predictive modeling. RESULTS The final analysis included 297,579 lumbar fusion patients. At 30 and 90 days, patients with nutritional malnutrition, dyslipidemia, and primary hypertension had significantly greater readmission rates than patients without MRFs (all P<0.01). At 180-days, all MRFs had significantly greater readmission rates than the non-MRF group (all P<0.001). Dyslipidemia demonstrated significantly greater rates of myocardial infarction at 90 days compared to all groups (all P<0.02). Nutritional malnutrition was associated with a significantly greater mortality rate than primary hypertension, non-MRF, and tobacco/nicotine use at 90 days (P<0.001) and only tobacco/nicotine use at 180 days (P=0.007). Predictive modeling showed increases of 0.77%, 1.70%, and 2.44% risk of readmission at 30, 90, and 180-days respectively per additional MRF (all P<0.001). CONCLUSIONS These findings highlight the negative impact each MRF has on patients following lumbar spinal fusion. Further longitudinal research is necessary to comprehensively characterize the effects of various MRFs on spine surgery outcomes.

Abstract
INTRODUCTION There is a paucity of research in the rates for sepsis and septic shock in the hip fracture population specifically, despite marked clinical and prognostic differences between these conditions. The purpose of this study was to determine the incidence, risk factors, and mortality rates for sepsis and septic shock as well as evaluate potential infectious causes in the surgical hip fracture population. METHODS The ACS-NSQIP (2015-2019) was queried for patients who underwent hip fracture surgery. A backward elimination multivariate regression model was used to identify risk factors for sepsis and septic shock. Multivariate regression that controlled for preoperative variables and comorbidities was used to calculate the odds of 30-day mortality. RESULTS Of 86,438 patients included, 871 (1.0%) developed sepsis and 490 (0.6%) developed septic shock. Risk factors for both postoperative sepsis and septic shock were male gender, DM, COPD, dependent functional status, ASA class ≥3, anemia, and hypoalbuminemia. Unique risk factors for septic shock were CHF and ventilator dependence. The 30-day mortality rate was 4.8% in aseptic patients, 16.2% in patients with sepsis, and 40.8% in patients who developed septic shock (p < 0.001). Patients with sepsis (OR 2.87 [95% CI 2.37-3.48], p < 0.001) and septic shock (OR 11.27 [95% CI 9.26-13.72], p < 0.001) had increased odds of 30-day mortality compared to patients without postoperative septicemia. Infections that preceded a diagnosis of sepsis or septic shock included urinary tract infections (24.7%, 16.5%), pneumonia (17.6%, 30.8%), and surgical site infections (8.5%, 4.1%). CONCLUSIONS The incidence of sepsis and septic shock after hip fracture surgery was 1.0% and 0.6%, respectively. The 30-day mortality rate was 16.2% in patients with sepsis and 40.8% in patients with septic shock. Potentially modifiable risk factors for both sepsis and septic shock were anemia and hypoalbuminemia. Urinary tract infections, pneumonia, and surgical site infections preceded the majority of cases of sepsis and septic shock. Prevention, early identification, and successful treatment of sepsis and septic shock are paramount to lowering mortality after hip fracture surgery.

Abstract
Introduction Wound dehiscence is the most common complication after spinal fusion procedures, resulting in an increase in mortality rate and hospital length of stay. Reconstruction of these wounds presents a challenge, as the spine is dependent on these implants for stability and must be maintained throughout the wound dehiscence treatment protocol. We describe a method for extending the thoracodorsal pedicle with an arteriovenous loop to permit an increased excursion of the latissimus dorsi muscle in patients with exposed implants and present the results of this procedure. Materials and Methods A retrospective review of patients treated with a latissimus free flap with saphenous vein pedicle extension for posterior spinal wounds from 2010 to 2020 were reviewed. Patient charts were reviewed for demographic information including comorbidities, previous spine operations, wound size and location, and postoperative complications including total flap loss, flap dehiscence, and need for secondary surgery. Results Six patients were identified who underwent a total of eight extended pedicle free flaps. Mean age was 64.8 years with a mean follow-up of 12.3 months (range, 6-20 months). Four wounds were in the cervicothoracic region with two wounds in the cervical region. Mean number of previous spine surgeries was 3.5 (range, 2-4). Mean wound size was 189 cm 2 with a mean vein graft length of 28 cm. Wound coverage was successful in five of six patients. Major complications occurred in five of six patients. Total flap loss occurred in two patients (33%) and both underwent a second extended latissimus flap from the contralateral side. Three patients developed postoperative flap dehiscence which resolved with regular dressing changes. Conclusion Extended pedicle latissimus flaps are an effective treatment for posterior spine wounds but are associated with a high complication rate, secondary to medically complex patients with multiple prior surgeries. Careful patient selection is critical for success.

Abstract
BACKGROUND Surgical site infection (SSI) may lead to vertebral osteomyelitis, diskitis, paraspinal musculoskeletal infection, and abscess, and remains a significant concern in postoperative management of spinal surgery. SSI is associated with greater postoperative morbidity and increased health care payments. METHODS We conducted a retrospective analysis using MarketScan to identify health care utilization payments and risk factors associated with SSI that occurs postoperatively. Known patient- or procedure-related risk factors were searched across those receiving spine surgery who developed postoperative infection. RESULTS A total of 33,061 patients who developed infection after spinal surgery were identified in Marketscan. Overall payments at 6 months, including index hospitalization for those with infection, were $53,573 and $46,985 for the cohort with no infection. At 24 months, the infection group had overall payments of $83,280 and $66,221 for no infection. Risk factors with largest effect size most likely to contribute to infection versus no infection were depression (4.6%), diabetes (3.7), anemia (3.3%), two or more levels (2.8%), tobacco use (2.2%), trauma (2.1%), neoplasm (1.8%), congestive heart failure (1.3%), instrumentation (1.1%), renal failure (0.9%), intravenous drug use (0.8%), and malnutrition (0.5%). CONCLUSIONS SSIs were associated with significant health care utilization payments at 24 months of follow-up. The following clinical and procedural risk factors appear to be predictive of postoperative SSI: depression, diabetes, anemia, two or more levels, tobacco use, trauma, neoplasm, congestive heart failure, instrumentation, renal failure, intravenous drug use, and malnutrition. Interpretation of modifiable and nonmodifiable risk factors for infection informs surgeons of expected postoperative course and preoperative risk for this most common and deleterious postoperative complication to spinal surgery.

Abstract
STUDY DESIGN Retrospective cross-sectional study. OBJECTIVES To determine if pre-operative albumin and CRP can predict post-operative infections after lumbar surgery. METHODS Patients who underwent an anterior lumbar interbody fusion (ALIF), posterior lumbar interbody fusion (PLIF), or lumbar discectomy were identified using a patient record database (PearlDiver) and were included in this retrospective study. Patients were stratified by Charlson Comorbidity Index (CCI) scores and pre-operative albumin and CRP status. Post-operative complications included deep infections and urinary tract infections within 3 months of the surgery and revisions within 1 year of the surgery. RESULTS 74,280 patients were included in this study. 21,903 had pre-operative albumin or CRP lab values. 7,191 (33%), 12,183 (56%), and 2,529 (12%) patients underwent an ALIF, PLIF, and a lumbar discectomy, respectively. 16,191 did not have any complication (74%). The most common complication was UTI (16%). Among all patients, hypoalbuminemia was a significant risk factor for deep infection and UTI after ALIF, deep infection, UTI, and surgical revision after PLIF, and deep infection after lumbar discectomy. Elevated CRP was a significant risk factor for deep infection after ALIF, UTI after PLIF, and deep infection after lumbar discectomy in patients with a CCI ≤ 3. CONCLUSIONS Pre-operative hypoalbuminemia and elevated CRP were significant risk factors for deep infection, UTI, and/or revision, after ALIF, PLIT, and/or lumbar discectomy. Future studies with a larger population of patients with low albumin and high CRP values are needed to further elaborate on the current findings.

METHODS Serum albumin and vitamin D (25-hydroxyvitamin D) levels were measured in patients with different spinal surgical approaches and various pathologies at a single institution. 112 patients were retrospectively identified for inclusion and stratified by age into 4 age groups and by pathology. The nutritional status of the patients was classified in vitamin D inadequacy (< 30ng/mL), vitamin D deficiency (<20ng/mL), and hypoalbuminemia (<3.5g/dL). Data was analyzed comparing vitamin D, and albumin means considering gender, age group, and pathologies. RESULTS Twenty-eight (25.2%) patients had hypoalbuminemia. There was no difference between gender (p = 0.988); there was a significant decrease in albumin concentration increasing the age (p < 0.001). The prevalence of hypoalbuminemia was significantly higher in patients with trauma, tumor and infection than in those patients with degenerative and deformity diseases (p = 0.003). The prevalence of vitamin D inadequacy was 33.7%, and that of deficiency was 62.2%, while severe deficiency (< 10 ng/mL) in 16.3%. The vitamin D concentration was significantly different among the pathologies (P = 0.047), the lower concentration occurring in patients with tumor. CONCLUSION Older patients, as well as patients with tumor and infectious pathologies, seem to have a higher prevalence of hypoalbuminemia, inferring malnutrition. There was a low epidemic level of vitamin D concentration, almost all patients presenting some degree of hypovitaminosis D, independent of age, gender and nutritional status.

Abstract
To date, no study has described the microbiological profile of surgical site infections (SSIs) after spine surgery in a tropical environment. The main objective of this study is to describe the microbiology and the risk factors of SSI after spinal surgery in a tropical climate. Our hypothesis is that the microbiology of SSIs in tropical areas is different to what is mainly described in temperate countries. As a consequence, the recommendation for antibiotic prophylaxis administered in the operative room, which mainly relays on the literature, might not be adequate in such countries. We included 323 consecutive patients who underwent a spinal intervention between 2017 and 2019, with a 2-year minimum follow-up. Objective ISO criteria were established in accordance with the criteria accepted by the Center of Disease Control in Atlanta. The identification of risk factors for SSI was carried out by uni- and multivariate analysis with a significance threshold of P < 0.05. The incidence of SSI was 7.7%. A total of 54.8% were in favor of a predominantly digestive origin of germs with an average of 1.68 bacteria found by ISO. Inadequate antibiotic prophylaxis was found in 54.8%. Age and body mass index were found to be independent risk factors for SSI. We report here an unusual microbiological profile of SSI with a predominance of gram-negative bacteria and a low proportion of Staphylococcus aureus and Staphylococcus epidermidis.

Abstract
OBJECTIVE The effect of malnutrition on outcomes after posterior lumbar fusion (PLF) remains understudied. This study analyzes the effect of malnutrition across a comprehensive range of body mass index (BMI) on complications after PLF. METHODS The Pearldiver Mariner database was queried between 2010 and 2020 using International Classification of Diseases (Ninth and Tenth Revisions) codes for malnutrition and Current Procedural Terminology codes for PLF. Patients were identified with preoperative BMI diagnosis codes and partitioned into one of the following BMI cohorts: underweight (BMI <20), normal (BMI 19-30), obese (BMI 30-40), and morbidly obese (BMI >40). An additional all-BMI cohort was created using patients with any BMI code. All cohorts were matched 1:3 to control patients within the same BMI group without malnutrition based on age, gender, and Charlson comorbidity index. Complication rates were calculated using the Pearson χ2 method with statistical significance set to P < 0.05. RESULTS The number of patients in each cohort were 1106 (all-BMI), 227 (underweight), 808 (normal), 667 (obese), and 449 (morbidly obese). Statistical analysis showed that the all-BMI cohort had greater odds of complications related to instrumentation (odds ratio [OR]: 2.28; P < 0.001), need for revision fusion (OR: 2.04; P < 0.001), pulmonary complications (OR: 1.45; P < 0.001), sepsis (OR: 2.89; P < 0.001), surgical site complications (OR: 1.87; P < 0.001), and urinary complications (OR: 1.41; P < 0.001). No difference was noted between the BMI-specific cohorts for complication risk. CONCLUSION Our analysis indicates that malnutrition may independently increase PLF complication risk. Surgeons may consider preoperative optimization for malnutrition patients to reduce complication risk.

Preoperative hypoalbuminemia and dialysis increase morbidity/mortality after spine surgery for primary pyogenic spinal infections (ACS-NSQIP Study). Surg Neurol Int 2022; 13:193. [PMID: 35673646 PMCID: PMC9168331 DOI: 10.25259/sni_330_2022] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2022] [Accepted: 04/20/2022] [Indexed: 12/16/2022] Open
Abstract
Background: We analyzed the role of hypoalbuminemia, dialysis, and other risk factors that increase morbidity/ mortality following surgery for primary pyogenic spinal infections (PSIs). The American College of Surgeons’ National Surgical Quality Improvement Program (ACS-NSQIP) that included 627 patients was utilized as our database. Methods: Primary spinal surgery for spondylodiscitis was evaluated in a ACS-NSQIP database involving 627 patients between 2010 and 2019. Outcome assessment included evaluation of 30-day postoperative morbidity, and mortality rates. Results: Within 30 postoperative days, complications occurred in 14.6% (92/627) of patients; 59 (9.4%) required readmission, and 39 (6.2%) required additional surgery. The most common complications were: wound infections, pneumonia, septic shock, and death (1.8%). Hypoalbuminemia (i.e., significantly associated with unplanned readmission and reoperation), and dialysis were the two major risk factors contributing to increased perioperative morbidity and mortality. Conclusion: Among 627 ACS-NSQIP patients undergoing primary surgery for PSIs, hypoalbuminemia and dialysis were associated with higher risks of major perioperative morbidity (i.e., within 30 postoperative days – mostly readmissions and reoperations) and mortality.

Abstract
Objective To explore the risk factors of hypoalbuminemia in patients with thoracic and lumbar tuberculosis and develop a scoring scale, according to which the patients with thoracic and lumbar tuberculosis were divided into 2 groups to, respectively calculate the perioperative albumin changes and to find out the preoperative albumin recommended value. Methods A total of 166 patients with thoracic and lumbar tuberculosis, who underwent spinal focus debridement between January 2012 to May 2020, were identified into 2 groups: with and without postoperative hypoalbuminemia (n = 131 and n = 35, respectively), recording and analyzing clinical characteristics by multivariate analysis to establish a scoring scale. Using this scale, patients with spinal tuberculosis were divided into a high-risk group and a low-risk group, and then, calculated the average decrease of postoperative albumin in both groups. Combined with the diagnostic threshold of hypoalbuminemia, we proposed the preoperative albumin safe values of the patients with thoracic and lumbar tuberculosis. Results A total of 131 of 166 patients experienced postoperative hypoalbuminemia after spinal focus debridement. Multivariate binary logistic regression analysis identified pulmonary tuberculosis (adjusted odds ratio = 0.270, p = 0.012), pre-operative serum albumin value (adjusted odds ratio = 0.754, p < 0.001), and operation time (adjusted odds ratio = 1.017, p = 0.002) as independent risk factors for the occurrence of postoperative hypoalbuminemia in patients with thoracic and lumbar tuberculosis. According to the OR value, the risk factors are assigned to make the scoring scale, the receiver operating characteristic (ROC) curve indicates that postoperative hypoalbuminemia rises when the score is greater than or equal to 4 points. The scoring scale is tested in the derivation set (166 patients) showed: sensitivity-51.9%, specificity-91.4%, and in the validation set (102 patients) showed: sensitivity-63.6% and specificity-86.1%. The perioperative albumin decreased value is 4.71 ± 2.66 g/L in the low-risk group and 8.99 ± 3.37 g/L in the high-risk group (p < 0.001). Conclusion Complicated with pulmonary tuberculosis, low preoperative albumin value and long operation time can lead to postoperative hypoalbuminemia in patients with thoracic and lumbar tuberculosis. The scoring scale can effectively assist physicians to evaluate whether patients with thoracic and lumbar tuberculosis develop hypoalbuminemia after surgery. The scale is simple and reliable and has clinical guiding significance. For low-risk patients and high-risk patients, preoperative albumin values should reach 40 and 44 g/L, respectively, to effectively avoid postoperative hypoalbuminemia.

Abstract
OBJECTIVES To determine the prevalence and factors associated with post-discharge prophylactic antibiotic use after spinal fusion and whether use was associated with decreased risk of surgical site infection (SSI). METHODS Persons aged 10-64 years undergoing spinal fusion between 1 January 2010 and 30 June 2015 were identified in the MarketScan Commercial Database. Complicated patients and those coded for infection from 30 days before to 2 days after the surgical admission were excluded. Outpatient oral antibiotics were identified within 2 days of surgical discharge. SSI was defined using ICD-9-CM diagnosis codes within 90 days of surgery. Generalized linear models were used to determine factors associated with post-discharge prophylactic antibiotic use and with SSI. RESULTS The cohort included 156 446 fusion procedures, with post-discharge prophylactic antibiotics used in 9223 (5.9%) surgeries. SSIs occurred after 2557 (1.6%) procedures. Factors significantly associated with post-discharge prophylactic antibiotics included history of lymphoma, diabetes, 3-7 versus 1-2 vertebral levels fused, and non-infectious postoperative complications. In multivariable analysis, post-discharge prophylactic antibiotic use was not associated with SSI risk after spinal fusion (relative risk 0.98; 95% CI 0.84-1.14). CONCLUSIONS Post-discharge prophylactic oral antibiotics after spinal fusion were used more commonly in patients with major medical comorbidities, more complex surgeries and those with postoperative complications during the surgical admission. After adjusting for surgical complexity and infection risk factors, post-discharge prophylactic antibiotic use was not associated with decreased SSI risk. These results suggest that prolonged prophylactic antibiotic use should be avoided after spine surgery, given the lack of benefit and potential for harm.

Abstract
Background Wound complications are associated with worse satisfaction and additional costs in patients undergoing posterior lumbar fusion (PLF) surgery, and the relationship between enhanced recovery after surgery (ERAS) pathway and wound complications remains poorly characterized. Methods In this retrospective single-center study, we compared 530 patients receiving ERAS pathway care with previous 530 patients in non-ERAS group. The primary aim of our study was to identify the relationship between the ERAS program and the incidence of postoperative wound-related complications and other complications following PLF surgery; other outcomes included the length of stay (LOS), 90-day hospital and rehabilitation center readmission. Results The average patient age was 65 yr. More patients with old cerebral infarction were in ERAS group (p < 0.01), and other demographics and comorbidities were similar between groups. Patients in the ERAS group had a lower incidence of postoperative wound-related complications than the non-ERAS group (12.4 vs. 17.8%, p = 0.02). The non-ERAS group had a significantly higher rate of wound dehiscence or poor wound healing (6% vs. 3%, p = 0.02). ERAS group had a lower incidence of severe postoperative hypoalbuminemia (serum albumin less than 30 g/L) (15.8% vs. 9.0% p < 0.01). Additionally, ERAS patients had shorter postoperative LOS (8.0 ± 1.5 vs. 9.5 ± 1.7, p < 0.01), lower rate of readmission within 90 days (1.9% vs. 6.4%, p < 0.01) and discharge to rehabilitation center (4.2% vs. 1.0%, p < 0.01). Conclusion ERAS pathway might help decrease the rates of postoperative wound complications and severe hypoalbuminemia following PLF surgery; additionally, it demonstrated that ERAS pathway was also associated with shorter LOS and lower rate of readmissions within 90 days.

Abstract
Background Many complications occur after surgery in patients with spinal tuberculosis (STB); however, the severity varies in different patients. The complications' severity is evaluated from grades I to V by the Clavien–Dindo classification (CDC), and grade V is the most severe. Most complications are mild, and only severe complications are life threatening, and thus, it is important to identify severe complications in patients with STB. The purpose of this study was to identify the risk factors of postoperative complication severity in patients with STB. Methods Between January 2012 and May 2021, a retrospective study included 188 patients that underwent STB debridement surgery. The patients were divided into three groups based on postoperative complication severity. Clinical characteristics measured included age, sex, body mass index (BMI), comorbidities of diabetes mellitus and pulmonary tuberculosis, alcohol use and smoking history, course of disease, preoperative hemoglobin, preoperative serum albumin, preoperative lymphocytes, preoperative erythrocyte sedimentation rate (ESR), preoperative C-reactive protein (CRP), surgical approach, operating time, blood loss during surgery, postoperative hemoglobin, and postoperative serum albumin. The clinical characteristics of patients with STB who developed postoperative complications were evaluated using logistic regression analysis. Results 188 patients suffered at least one postoperative complication; 77, 91, and 20 patients experienced grade I, II, and III-IV complications, respectively. In the univariate analysis, sex, diabetes mellitus, postoperative hemoglobin, and postoperative albumin are statistically significant. In the multivariable analysis, postoperative albumin (adjusted odds ratio (OR) = 0.861, P < 0.001) was an independent risk factor of the postoperative complication severity in patients with STB. Receiver operating characteristic (ROC) analysis showed that the optimal cutoff values for postoperative albumin were 32 g/L (sensitivity: 0.571, specificity: 0.714, area under the ROC curve: 0.680) and 30 g/L (sensitivity: 0.649, specificity: 0.800, area under the ROC curve: 0.697) for grade II and grade III-IV complications, respectively. Conclusions Postoperative albumin is an independent risk factor for postoperative complication severity in patients with STB. The improvement of postoperative albumin levels may reduce the risk of severe complications in patients with STB.

Risk Factors for Postoperative Deep Infection after Instrumented Spinal Fusion Surgeries for Degenerative Spinal Disease: A Nationwide Cohort Study of 194,036 Patients. J Clin Med 2022; 11:jcm11030778. [PMID: 35160230 PMCID: PMC8836461 DOI: 10.3390/jcm11030778] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2021] [Revised: 01/12/2022] [Accepted: 01/29/2022] [Indexed: 02/01/2023] Open
Abstract
Previous studies to identify risk factors for postoperative deep infection following instrumented spinal fusion surgery for degenerative spinal disease are based on insufficient information and have limited use in clinical practice. This study aims to fill this gap by assessing the risk factors and their adjusted relative risks through a comprehensive analysis, including all core information. In this nationwide, population-based, cohort study, data were obtained from the Korean National Health Insurance claims database between 1 January 2014, and 31 December 2018. This study included a cohort of 194,036 patients older than 19 years, who underwent instrumented spinal fusion surgery for degenerative spinal disease. We divided this population into cases (patients with postoperative deep infection) and controls (patients without postoperative deep infection); risk factors for postoperative deep infection were determined by multivariable analysis. The definition of postoperative deep infection varied, and sensitivity analyses were performed according to each definition. The estimates of all the statistical models were internally validated using bootstrap samples. The study included 767 patients (0.39%) with postoperative deep spinal infections and 193,269 controls. The final multivariable model identified the following variables as significant risk factors for postoperative deep infection: age between 60–69 years (OR = 1.6 [1.1–2.3]); age between 70–79 years (OR = 1.7 [1.2–2.5]); age > 80 years (OR = 2.1 [1.3–3.2]); male sex (OR = 1.7 [1.5–2.0]); rural residence (OR = 1.3 [1.1–1.5]); anterior cervical approach (OR = 0.2 [0.1–0.3]); posterior cervical approach (OR = 0.5 [0.2–1.0]); multiple approaches (OR = 1.4 [1.2–1.6]); cerebrovascular disease (OR = 1.5 [1.2–1.8]); peripheral vascular disease (OR = 1.3 [1.1–1.5]); chronic pulmonary disease (OR = 1.2 [1.0–1.4]); rheumatologic disease (OR = 1.6 [1.3–2.1]); liver disease (OR = 1.4 [1.1–1.7]); diabetes (OR = 1.5 [1.3–1.7]); hemiplegia or paraplegia (OR = 2.2 [1.5–3.3]); allogenous transfusion (OR = 1.6 [1.3–1.8]); and use of systemic steroids over 2 weeks (OR = 1.5 [1.1–2.0]). Our results, which are based on homogenous patient groups, provide clinicians with an acceptable tool for comprehensive risk assessment of postoperative deep infection in patients who will undergo instrumented spinal fusion surgery for degenerative spinal disease.

Postoperative hypoalbuminemia is an independent predictor of 1-year mortality after surgery for geriatric intertrochanteric femoral fracture: A retrospective cohort study. Medicine (Baltimore) 2021; 100:e28306. [PMID: 34941120 PMCID: PMC8701452 DOI: 10.1097/md.0000000000028306] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/24/2020] [Accepted: 11/26/2021] [Indexed: 01/05/2023] Open
Abstract
Preoperative hypoalbuminemia from malnutrition is associated with increased morbidity and mortality after geriatric hip fracture surgery. However, little is known regarding the correlation between postoperative hypoalbuminemia and mortality. This study aimed to evaluate whether postoperative hypoalbuminemia could predict 1-year mortality after intertrochanteric femoral fracture surgery in elderly patients.The medical records of 263 geriatric patients (age ≥65 years) who underwent intertrochanteric femoral fracture surgery between January 2013 and January 2016 in a single hospital were reviewed retrospectively. The patients were allocated to 2 groups based on lowest serum albumin levels within 2 postoperative days (≥3.0 g/dL [group 1, n = 46] and <3.0 g/dL [group 2, n = 217]. Data between the non-survival and survival groups were compared. Multivariable logistic regression analysis was conducted to identify the independent predictor for 1-year mortality.The 1-year mortality rate was 16.3% after intertrochanteric femoral fracture surgery. Multivariable logistic regression analysis revealed that postoperative hypoalbuminemia was significantly associated with 1-year mortality (adjusted odds ratio, 8.03; 95% confidence interval, 1.37-47.09; P = .021). The non-survival group showed a significantly increased incidence of postoperative hypoalbuminemia (95.4% vs 80.0%, P = .015) and intensive care unit admission (11.6% vs 2.7%, P = .020), older age (82.5 ± 5.8 years vs 80.0 ± 7.2 years, P = .032), lower body mass index (20.1 ± 3.2 kg/m2 vs 22.4 ± 3.8 kg/m2, P < .001), and increased amount of transfusion of perioperative red blood cells (1.79 ± 1.47 units vs 1.43 ± 2.08 units, P = .032), compared to the survival group.This study demonstrated that postoperative hypoalbuminemia is a potent predictor of 1-year mortality in geriatric patients undergoing intertrochanteric femoral fracture surgery. Therefore, exogenous albumin administration can be considered to improve postoperative outcomes and reduce the risk of mortality after surgery for geriatric hip fracture.

Clin Neurol Neurosurg 2021; 210:107009. [PMID: 34781089 DOI: 10.1016/j.clineuro.2021.107009] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2021] [Revised: 10/22/2021] [Accepted: 10/24/2021] [Indexed: 12/22/2022]
Abstract
STUDY DESIGN Retrospective review of a prospectively collected national database. OBJECTIVE To evaluate the predictive value of hypoalbuminemia on outcomes in surgical spine oncology patients. SUMMARY OF BACKGROUND DATA It is well documented that patients with hypoalbuminemia (albumin <3.5) have significantly higher rates of surgical morbidity and mortality than patients with normal albumin (>3.5 g/dl). We evaluated outcomes for metastatic oncologic spine surgery patients based on pre-operative albumin levels. MATERIALS AND METHODS Patients who underwent surgery for metastatic spine disease were identified in the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database from 2006 to 2016. Three groups were established: patients with normal albumin (>3.5 g/dl), mild hypoalbuminemia (2.6 g/dl - 3.4 g/dl), and severe hypoalbuminemia (<=2.5 g/dl). A multivariate analysis was used to assess the association between albumin levels and mortality within 30 days of surgical intervention. RESULTS A total of 700 patients who underwent surgery for metastatic spinal disease and had pre-operative albumin levels available were identified; 64.0% had normal albumin (>3.5 g/dl), 29.6% had mild hypoalbuminemia, and 6.4% had severe hypoalbuminemia. The overall 30-day mortality was 7.6% for patients with normal albumin, 15.9% for patients with mild hypoalbuminemia, and 44.4% for patients with severe hypoalbuminemia. On multivariate analysis, patients with mild hypoalbuminemia (OR 1.7 95% CI: 1.0-3.0 p = 0.05) and severe hypoalbuminemia (OR 6.2 95% CI: 2.8-13.5 p < 0.001) were more likely to expire within 30 days compared to patients with preoperative albumin above 3.5 g/dl. CONCLUSION In this study, albumin level was found to be an independent predictor of 30-day mortality in patients who underwent operative intervention for metastatic spinal disease. Patients with severe hypoalbuminemia had a 7-fold increased risk when compared with those who had normal albumin. While these findings need to be validated by future studies, we believe they will prove useful for preoperative risk stratification and surgical decision-making.

Abstract
Hypoalbuminemia is a potentially modifiable risk factor associated with adverse events following total knee arthroplasty. The present study aimed to evaluate whether hypoalbuminemia similarly predisposes to adverse events following unicompartmental knee arthroplasty (UKA). Patients who underwent UKA during 2006-2018 were identified through the American College of Surgeons National Surgical Quality Improvement Program. Only patients with preoperative serum albumin concentration were included. Outcomes were compared between patients with and without hypoalbuminemia (serum albumin concentration < 3.5 g/dL). All associations were adjusted for demographic, comorbidity, and laboratory differences between populations. A total of 11,342 patients were identified, of whom 6,049 (53.3%) had preoperative serum albumin laboratory values available for analysis. After adjustment for potential confounders, patients with hypoalbuminemia had a greater than 2-fold increased probability for occurrence of any complication (7.02% vs. 2.23%, p = 0.009) and a 4-fold increased probability of receiving a blood transfusion (1.81% vs. 0.25%, p = 0.045). Among procedures performed as inpatients, mean postoperative length of stay (LOS) was longer in patients with hypoalbuminemia (2.2 vs. 1.8 days; p = 0.031). Hypoalbuminemia is independently associated with complications and increased LOS following UKA and a marker for patients at higher risk of postoperative complications. Patients should be screened for hypoalbuminemia and nutritional deficiencies addressed prior to UKA.

[PMID: 34733105 PMCID: PMC8558601 DOI: 10.1177/11786388211054664] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2021] [Accepted: 10/03/2021] [Indexed: 01/03/2023] Open
Abstract
Introduction Degenerative cervical myelopathy (DCM) is the commonest cause of adult spinal cord impairment worldwide, encompassing chronic compression of the spinal cord, neurological disability and diminished quality of life. Evidence on the contribution of environmental factors is sparse; in particular, the role of nutrition in DCM is unknown. The objective of this review was to assess the effect of nutrition on DCM susceptibility, severity and surgical outcome. Methods A systematic review in MEDLINE and Embase was conducted following PRISMA guidelines. Full-text papers in English papers, focussing on cervical myelopathy and nutrition, published before January 2020 were considered eligible. Quality assessments were performed using the GRADE assessment tool. Patient demographics, nutritional factor and DCM outcomes measures were recorded. Relationships between nutritional factors, interventions and disease prognosis were assessed. Results In total, 5835 papers were identified of which 44 were included in the final analysis. DCM patients with pathological weight pre-operatively were more likely to see poorer improvements post-surgically. These patients experienced poorer physical and mental health improvements from surgery compared to normal weight patients and were more likely to suffer from post-operative complications such as infection, DVT, PE and hospital readmissions. Two trials reporting benefits of nutritional supplements were identified, with 1 suggesting Cerebrolysin to be significant in functional improvement. An unbalanced diet, history of alcohol abuse and malnourishment were associated with poorer post-operative outcome. Conclusion Although the overall strength of recommendation is low, current evidence suggests nutrition may have a significant role in optimising surgical outcome in DCM patients. Although it may have a role in onset and severity of DCM, this is a preliminary suggestion. Further work needs to be done on how nutrition is defined and measured, however, the beneficial results from studies with nutritional interventions suggest nutrition could be a treatment target in DCM.

Abstract
Introduction Local infection and prolonged fluid discharge account for most complications in lumbar spine surgery. This report is a brief description of a useful technique for revision of complicated, draining wounds with surprisingly positive results that otherwise frequently require multiple surgical interventions. Technical Note We describe the postoperative course of three patients, with prolonged and continuous serosanguineous discharge from the skin incision, who underwent wound revision with multilayered mattress stitches after open decompressive or instrumented spinal surgery. For this purpose, a thick monofilament suture is passed through the skin, subcutaneous fatty tissue, and paravertebral muscle in the fashion of a vertical mattress stitch while the loop above the skin level is augmented using a soft silicone capillary drainage to distribute tension along the wound margin. Conclusions None of the patients treated with the multilayered mattress stitches required further surgical intervention. In this small case series, the multilayered mattress stitches augmented with soft silicone tubing were a useful technique for treating complicated lumbar surgical wounds with prolonged serosanguineous discharge.

Abstract
PURPOSE The purpose of this study was to test the null hypothesis that there is no association between perioperative laboratory markers (serum albumin and hemoglobin A1c [HbA1c]) and incidence of surgical site infection (SSI) after soft tissue upper extremity surgery. METHODS We analyzed patient-level data from a large, insurance-based database containing supplemental laboratory results. We identified patients undergoing soft tissue upper extremity surgery (defined as carpal tunnel release, trigger finger release, wrist ganglion excision, cubital tunnel release, Dupuytren partial fasciectomy, or first dorsal compartment release) with serum albumin or HbA1c measurements within 90 days of surgery. We stratified patients into cohorts based on serum albumin concentration (<3.5 g/dL) and HbA1c (≥7%) thresholds. The primary outcome was incidence of SSI within 30 days following surgery. We constructed multivariable logistic regression models to adjust for patient demographics and baseline comorbidities using the Elixhauser comorbidity index. RESULTS Patients with hypoalbuminemia experienced an SSI incidence of 3.5% compared to 0.9% in patients with normal serum albumin. In multivariable analysis, the odds ratio of SSI with hypoalbuminemia was 3.32 (95% CI, 2.32-4.65). Patients with HbA1c ≥ 7% experienced an SSI incidence of 1.1% compared to 0.7% in patients with HbA1c < 7%. Multivariable analysis revealed odds ratios for SSI of 1.47 (95% CI, 1.02-2.11) in patients with HbA1c ≥ 7% compared to those with HbA1c < 7%. CONCLUSIONS Hypoalbuminemia and elevated HbA1c (in patients with diabetes) are risk factors for SSI within 30 days following soft tissue upper extremity surgery. Preoperative measurement of these laboratory markers may be a useful tool for risk stratification and identification of high-risk patients for nutritional or glycemic optimization.

Abstract
PURPOSE The purpose of this study was to investigate the relationship and to determine potential usefulness of serum albumin as a biomarker for predicting postoperative diabetic foot ulcer (DFU) healing. DESIGN A retrospective study. SUBJECTS AND SETTING The sample comprised 266 inpatients with type 2 diabetes receiving care in The First Affiliated Hospital of Sun Yat-sen University, Guangzhou, China. Among them, 174 had DFUs and underwent surgery for foot DFUs including amputation, skin grafting, and flap procedures. A comparison group consisted of 92 inpatients without a DFU or surgery. METHODS The association between healing and preoperative albumin levels was analyzed via a logistic regression model and receiver operating characteristic (ROC) curve. RESULTS The albumin value of patients with DFU grade 3 or more (3.23 ± 0.58 g/dL) was lower than that of patients with DFU grade 1-2 (3.58 ± 0.5 g/dL), and both were lower than that of the comparison group (3.89 ± 0.3 g/dL). Patients with a DFU with hypoalbuminemia (<3.5 g/dL) had a 2.5-fold higher risk of nonhealing at postoperative 28 days than patients with normal levels (odds ratio = 3.51; 95% confidence interval, 1.75-7.06; P < .001). For patients with a DFU overall, the ROC curve showed a preoperative albumin cutoff of 3.44 g/dL for DFU wound healing. CONCLUSIONS For patients with a DFU undergoing surgery, preoperative serum albumin may be used as a biomarker for predicting postoperative healing.

Abstract
Malnutrition is a risk factor for postoperative infectious complications of elderly patients undergoing posterior lumbar arthrodesis. At present, there is no gold standard for nutrition screening tools. We analyzed the value of predicting infectious complications among elderly patients over 70 years undergoing posterior lumbar arthrodesis by comparing the MNA-SF and GNRI. Demographic data, anthropometric measurements, serum albumin, surgical data and the occurrence of infectious complications and LOS were collected. Mini Nutritional Assessment short form (MNA-SF), Geriatric Nutritional Risk Index (GNRI) were performed within 24 h before surgery. Multivariable logistic regression analyses were used to identify predictors of infectious complications. The discriminatory performances of GNRI and MNA-SF scores for the occurrence of infectious complications were determined by receiver operating characteristic curves (ROC) analyses and the area under the curve (AUC). The study included 252 patients with a median age of 76.82 ± 6.41 years (range 70-84 years), and 142 patients (56.3%) were female. There were no significant differences in infectious complications (p = 0.236) and LOS (p = 0.580) among different GNRI categories. 27.3% malnourished patients evaluated by the MNA-SF suffered from infectious complications and 10.1% patients at risk of malnourished had infectious complications. Those patients had statistically significant higher prevalence of infectious complications (p = 0.002) and longer LOS (p = 0.023) than well-nourished patients. Multivariable analysis revealed that preoperative malnutrition and at risk of malnourished by the MNA-SF was significantly associated with infections. The area under the curve (AUC) of MNA-SF was 0.754, which was significantly high than AUC of GNRI (0.623) (Delong's test, p = 0.033). This study demonstrated that MNA-SF is a simple and effective tool for predicting the risk of infectious complications in elderly patients undergoing posterior lumbar arthrodesis.

Abstract
BACKGROUND Modifiable risk factors (MRFs) represent patient variables associated with increased complication rates that may be prevented. There exists a paucity of studies that comprehensively analyze MRF subgroups and their independent association with postoperative complications in patients undergoing cervical spine surgery. Therefore, the purpose of this study is to compare outcomes between patients receiving cervical spine surgery with reported MRFs. METHODS Retrospective analysis of the Nationwide Readmissions Database (NRD) from the years 2016 and 2017, a publicly available and purchasable data source, to include adult patients undergoing cervical fusion. MRF cohorts were separated into three categories: substance abuse (alcohol, tobacco/nicotine, opioid abuse); vascular disease (hypertension, dyslipidemia); and dietary factors (malnutrition, obesity). Three-way nearest-neighbor propensity score matching for demographics, hospital, and surgical characteristics was implemented. FINDINGS We identified 9601 with dietary MRFs (D-MRF), 9654 with substance abuse MRFs (SA-MRF), and 9503 with vascular MRFs (V-MRF). Those with d-MRFs had significantly higher rates of medical complications (9.3%), surgical complications (8.1%), and higher adjusted hospital costs compared to patients with SA-MRFs and V-MRFs. Patients with d-MRFs (16.3%) and V-MRFs (14.0%) were independently non-routinely discharged at a significantly higher rate compared to patients with SA-MRFs (12.6%) (p<0.0001 and p = 0.0037). However, those with substance abuse had the highest readmission rate and were more commonly readmitted for delayed procedure-related infections. INTERPRETATION A large proportion of patients who receive cervical spine surgery have potential MRFs that uniquely influence their postoperative outcomes. A thorough understanding of patient-specific MRF subgroups allows for improved preoperative risk stratification, tailored patient counseling, and postoperative management planning. FUNDING None.

Prevalence and risk factors of surgical site infection after closed isolated patella fracture surgery: A prospective cohort study. INTERNATIONAL ORTHOPAEDICS 2021; 45:2129-2139. [PMID: 34014369 DOI: 10.1007/s00264-021-05070-w] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 01/28/2021] [Accepted: 05/10/2021] [Indexed: 12/11/2022]
Abstract
PURPOSE Surgical site infection (SSI) after patella fracture surgery could be devastating and challenging. There is no large sample size study to investigate the prevalence and risk factors of it. The purpose of this study was to address this clinical issue. METHODS A total of 820 patients who underwent patella fracture surgery between October 2014 and December 2018, were included. Demographic data, fracture type, injury mechanism, pre-operative stay, surgery-related variables, and pre-operative laboratory indexes were obtained from a prospective database. The optimum cutoff value of surgery duration was detected by receiver operating characteristic analysis. Univariate analysis and multivariate analysis were performed to determine the risk factors. RESULTS A total of 17 patients developed SSI after patella fracture surgery, indicating a prevalence of 2.1%, with 11 cases (1.3%) for superficial infection and six cases (0.8%) for deep infection. After adjustment of multiple variables, current smoking, (OR, 18.6, CI, 3.5-99.0); albumin < 35 g/L, (OR, 7.4, CI, 1.1-52.3); diabetes mellitus, (OR, 8.8, CI, 1.3-59.4) and surgery duration > 79.5 minutes, (OR, 13.2, CI, 1.5-117.3) were identified to be independent risk factors of SSI after patella fracture surgery (p < 0.05). CONCLUSION The prevalence of SSI in patients with closed isolated patella fracture was 2.1%, with 1.3% for superficial and 0.8% for deep infection. We recommend individualized risk stratification and targeted interventions for patients with risk factors (current smoking, albumin < 35 g/L, diabetes mellitus, and surgery duration > 79.5 minutes).

Consensus statement for perioperative care in lumbar spinal fusion: Enhanced Recovery After Surgery (ERAS®) Society recommendations. Spine J 2021; 21:729-752. [PMID: 33444664 DOI: 10.1016/j.spinee.2021.01.001] [Citation(s) in RCA: 150] [Impact Index Per Article: 50.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2020] [Revised: 12/02/2020] [Accepted: 01/04/2021] [Indexed: 02/03/2023]
Abstract
BACKGROUND Enhanced Recovery After Surgery (ERAS) evidence-based protocols for perioperative care have led to improvements in outcomes in numerous surgical areas, through multimodal optimization of patient pathway, reduction of complications, improved patient experience and reduction in the length of stay. ERAS represent a relatively new paradigm in spine surgery. PURPOSE This multidisciplinary consensus review summarizes the literature and proposes recommendations for the perioperative care of patients undergoing lumbar fusion surgery with an ERAS program. STUDY DESIGN This is a review article. METHODS Under the impetus of the ERAS® society, a multidisciplinary guideline development group was constituted by bringing together international experts involved in the practice of ERAS and spine surgery. This group identified 22 ERAS items for lumbar fusion. A systematic search in the English language was performed in MEDLINE, Embase, and Cochrane Central Register of Controlled Trials. Systematic reviews, randomized controlled trials, and cohort studies were included, and the evidence was graded according to the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. Consensus recommendation was reached by the group after a critical appraisal of the literature. RESULTS Two hundred fifty-six articles were included to develop the consensus statements for 22 ERAS items; one ERAS item (prehabilitation) was excluded from the final summary due to very poor quality and conflicting evidence in lumbar spinal fusion. From these remaining 21 ERAS items, 28 recommendations were included. All recommendations on ERAS protocol items are based on the best available evidence. These included nine preoperative, eleven intraoperative, and six postoperative recommendations. They span topics from preoperative patient education and nutritional evaluation, intraoperative anesthetic and surgical techniques, and postoperative multimodal analgesic strategies. The level of evidence for the use of each recommendation is presented. CONCLUSION Based on the best evidence available for each ERAS item within the multidisciplinary perioperative care pathways, the ERAS® Society presents this comprehensive consensus review for perioperative care in lumbar fusion.

Abstract
BACKGROUND Rotator cuff repair (RCR) is a common orthopedic procedure frequently performed in the outpatient setting. Malnutrition, as assessed by preoperative serum albumin <3.5 g/dL, has been independently associated with significantly higher risks of multiple adverse outcomes in several orthopedic procedures. The effect of preoperative hypoalbuminemia on short-term outcomes of RCR was previously unknown. HYPOTHESIS we hypothesized that preoperative serum albumin <3.5 g/dL would be associated with higher odds of post-operative admission and prolonged length of stay. METHODS This study represents a retrospective analysis of the American College of Surgeons National Surgical Quality Improvement Program database (NSQIP) for patients undergoing RCR between 2011 and 2015. RESULTS Multivariate regression analysis adjusted for sex, ASA classification, age, BMI, and diabetes status (Table 3) showed preoperative hypoalbuminemia conferred a significantly increased adjusted odds ratio of postoperative admission (adjusted odds ratio 1.711, CI 1.134-2.583, p = 0.011) and extended length of stay (adjusted odds ratio 2.073, CI 1.073-4.003, p = 0.030). CONCLUSION Malnutrition as assessed by preoperative serum albumin <3.5 g/dL is significantly associated with increased odds of hospital admission and extended length of stay following arthroscopic RCR. This has clinical implications in surgical patient selection and risk stratification. LEVEL OF EVIDENCE III, Retrospective cohort study.

Abstract
Background/aim To investigate the risk factors for evisceration in a gynecological oncology population. The secondary aim was to evaluate the impact of evisceration on survival. Materials and methods Inclusion criteria consisted of having had an elective surgery performed through a xiphoidopubic incision in our institution and having a gynecological malignancy based on pathology. A total of 198 patients were evaluated, 54 with evisceration and 144 without evisceration. Due to the widely varied prognosis of female genital cancers, the survival was analyzed on a homogenized group, including only 62 patients with primary advanced stage epithelial ovarian-tubal-peritoneal cancer. Results The preoperative factors associated with evisceration in the univariate analysis were old age, high body mass index (BMI), hypertension, smoking, comorbidities, high American Society of Anesthesiologist (ASA) score (3 and 4), and low preoperative albumin level. The associated intraoperative factors were bleeding volume, receiving more than two units of erythrocyte suspension or fresh frozen plasma, and having had a major operation. The associated postoperative factors were the albumin transfusion and the antibiotic use in the early postoperative period. In the multivariate analysis, smoking, low levels of preoperative albumin, high BMIs, and high ASA scores (3 and 4) were independent prognostic factors for evisceration. Evisceration was not associated with recurrence and survival in the patients with primary advanced stage epithelial ovarian-tubal-peritoneal cancer. Conclusion Smoking, preoperative hypoalbuminemia, obesity, and high ASA scores (3and 4) were the prognostic factors for evisceration. Short-term modifiable factors such as smoking cessation and improved nutritional status should be considered in elective gynecological oncology surgeries. Evisceration had no impact on survival and recurrence in the patients with primary advanced stage epithelial ovarian-tubal-peritoneal cancer.

Abstract
OBJECTIVES Evaluate the relationship of nutrition parameters and the modified frailty index (mFI) on postsurgical complications within a young patient population sustaining lower extremity orthopaedic trauma. DESIGN Retrospective observational cohort study. SETTING Urban, American College of Surgeons-Verified, Level-1, Trauma Center. PATIENTS/PARTICIPANTS Seventeen-thousand one hundred nine adult patients under the age of 65 sustaining lower extremity fractures undergoing operative intervention from 2006 to 2018. MAIN OUTCOME MEASURES On admission, mFI and albumin levels were obtained, as well as complication data. Statistical analysis was used to analyze the association between frailty, malnutrition, and postoperative complications. Patients were stratified, healthy (mFI ≤1, albumin ≥3.5 g/dL), malnourished (mFI ≤1, albumin <3.5 g/dL), frail (mFI ≥2, albumin ≥3.5 g/dL), and frail and malnourished (mFI ≥2, albumin <3.5 g/dL). RESULTS 60.4% of patients were healthy, 18.8% were malnourished, 11.7% were frail, and 9.0% were frail and malnourished. Frailty and/or malnourishment on admission predicted significantly higher odds of postoperative complications and mortality when compared with healthy patients. Frailty and malnourishment in conjunction predicted a significantly higher odds ratio of 1.46 (1.22-1.75) for developing postoperative complications when compared with the only malnourished. This was also observed when compared with the only frail (odd ratio: 1.61, P < 0.001); however, there was also a 2.72 (P < 0.001) increased odds of mortality. CONCLUSIONS Frailty and malnutrition in conjunction predicts a subset of patients with a higher risk of postoperative complications beyond that of frailty or malnutrition in isolation. Identification of these physiological states on admission allows for interventional opportunities during hospitalization. LEVEL OF EVIDENCE Prognostic Level III.

Abstract
OBJECTIVE The consequences of failed spinal hardware secondary to wound complications can increase the burden on the patient while also significantly escalating the cost of care. The objective of this study was to demonstrate the effectiveness of a protocol-based multidisciplinary approach in optimizing wound outcome in complex oncological spine care patients. METHODS A retrospective consecutive case series was performed from 2015 to 2019 of all patients who underwent oncological spine surgery. A protocol was established to identify oncological patients at high risk for potential wound complications. Preoperative and postoperative treatment plans were developed by the multidisciplinary tumor board team members. Wound healing risk factors such as diabetes, obesity, prior spine surgery, pre- or postoperative chemotherapy or radiation exposure, perioperative steroid use, and poor nutritional status were recorded. Operative details, including the regions of spinal involvement, presence of instrumentation, and number of vertebral levels operated on, were reviewed. Primary outcomes were the length of hospitalization and major (requiring reoperation) and minor wound complications in the setting of the aforementioned identified risk factors. RESULTS A total of 102 oncological cases were recorded during the 5-year study period. Of these patients, 99 had local muscle flap reconstruction with layered closure over their surgical hardware. The prevalence of smoking, diabetes, and previous spine surgery for the cohort was 21.6%, 20.6%, and 27.5%, respectively. Radiation exposure was seen in 72.5% of patients (37.3% preoperative vs 48% postoperative exposure). Chemotherapy was given to 66.7% of the patients (49% preoperatively and 30.4% postoperatively). The rate of perioperative steroid exposure was 60.8%. Prealbumin and albumin levels were 15.00 ± 7.47 mg/dL and 3.23 ± 0.43 mg/dL, respectively. Overall, an albumin level of < 3.5 mg/dL and BMI < 18.5 were seen in 64.7% and 13.7% of the patients, respectively. The mean number of vertebral levels involved was 6.76 ± 2.37 levels. Instrumentation of 7 levels or more was seen in 52.9% of patients. The average spinal wound defect size was 22.06 ± 7.79 cm. The rate of minor wound complications, including superficial skin breakdown (epidermolysis) and nonoperative seromas, was 6.9%, whereas that for major complications requiring reoperation within 90 days of surgery was 2.9%. CONCLUSIONS A multidisciplinary team approach utilized in complex multilevel oncological spine reconstruction surgery optimizes surgical outcomes, reduces morbidities, and improves care and satisfaction in patients with known risk factors.

Abstract
OBJECTIVES To determine the rate of and main risk factors for postoperative infection in cancer patients who underwent spine surgery in the last 5 years in order to determine whether there is an association between postoperative infection and increased mortality during hospitalization. METHODS All cancer patients who underwent surgical procedures between January 2015 and December 2019 at a single hospital specializing in spine cancer surgery were analyzed. The primary outcome of interest was postoperative infection. Bivariate logistic regression was used to estimate the odds ratio and 95% confidence interval for each variable in relation to the occurrence of infection. RESULTS We evaluated 324 patients, including 176 men (54.3%) and 148 women (45.7%) with a mean age of 56 years. The incidence of postoperative infection was 20.37%. Of the 324 patients, 39 died during hospitalization (12%). CONCLUSIONS Surgical time greater than 4 hours, surgical instrumented levels greater than 6, and an Eastern Cooperative Oncology Group of 3 or 4 were associated with an increased risk of postoperative infection, but these factors did not lead to an increase in mortality during hospitalization.

Abstract
STUDY DESIGN Multicenter retrospective study. OBJECTIVE The aim of this study was to identify specific risk factors for increased length of stay (LOS) in the management of acute surgical site infection (SSI) following spinal surgery. SUMMARY OF BACKGROUND DATA Postoperative SSI is a serious complication of spinal surgery and is known to be associated with increased LOS and additional cost. Although many risk factors contribute to the development of SSI following spinal surgery, little is known about risk factors associated with the treatment of SSI that contribute to increased LOS. METHODS Patients at two institutions experiencing deep SSI following spinal surgery between January 2009 and December 2016 were identified. The patients were divided into two groups depending upon the median LOS attributable to SSI. The effects of patient characteristics, comorbidities, disease history, and invasiveness of the elective surgery on the risk of increased LOS were determined using univariate analyses and multivariate logistic regression. RESULTS Of the 1656 spinal surgery cases, 40 (2.4%) experienced deep SSI. The median LOS was 67 days. Multivariate logistic regression analysis revealed that hypoalbuminemia during hospitalization was associated with increased LOS (odds ratio 0.042, confidence interval 0.005-0.342; P = 0.003). We determined the appropriate diagnostic cutoff of hypoalbuminemia during hospitalization using receiver-operating characteristic curves. A serum albumin level <3.1 g/dL (sensitivity, 86.4%; specificity, 75.0%; area under the curve, 0.84) was indicative of a longer hospital stay. CONCLUSION Low serum albumin level during hospitalization was an independent risk factor for increased LOS in the treatment of SSI following spinal surgery. When the serum albumin level is <3.1 g/dL in patients with SSI, we should consider interventions aimed at correcting this hypoalbuminemia. LEVEL OF EVIDENCE 4.

Abstract
Background Although serum albumin levels are increasingly used as an indicator of nutritional status in the clinic, the relationship between perioperative hypoalbuminemia and wound complications after posterior lumbar interbody fusion in the treatment of lumbar degenerative disease remains ambiguous. The aim of this study was to evaluate perioperative serum albumin in relation to postoperative wound complications after posterior lumbar interbody fusion in the treatment of single-segment lumbar degenerative disease. Material and methods We reviewed patients who underwent single-segment posterior lumbar interbody fusion surgery from December 2014 to April 2017 in the Department of Orthopedics at the First Affiliated Hospital of Chongqing Medical University. Perioperative (preoperative and early postoperative) serum albumin levels were assessed in all patients and were used to quantify nutritional status. We divided the patients into a surgical wound dehiscence (SWD) group and a normal wound healing group and into a surgical site infection (SSI) group and a non-SSI group. To evaluate the relationship between perioperative serum albumin level and postoperative wound complications, we conducted univariate and multiple logistic regression analyses. Results A total of 554 patients were enrolled in the study. The univariate and multiple logistic regression analysis of these differences showed that preoperative serum albumin < 3.5 g/dl (P = 0.001) and postoperative serum albumin < 3.0 g/dl (P = 0.001) were significantly correlated to SWD. There were also significant differences between the SSI groups in terms of preoperative serum albumin < 3.5 g/dl (P = 0.001) and chronic steroid use (P = 0.003). Additionally, the increased hospitalization costs (P < 0.001) and length of hospitalization (P < 0.001) were statistically significant for patients with perioperative hypoalbuminemia. Conclusions For patients who underwent single-segment posterior lumbar interbody fusion surgery, we need to pay more attention to perioperative hypoalbuminemia and chronic steroid use, which are more likely to be associated with increased wound complications, hospitalization costs, and length of hospitalization after surgery. Adequate assessment and management of these risk factors will help reduce wound complications and hospital stays for surgical patients and will save medical costs.

Risk of malnutrition in orthopedic trauma patients with surgical site infections is associated with increased morbidity and mortality - a 3-year follow-up study. Injury 2020; 51:2219-2229. [PMID: 32620329 DOI: 10.1016/j.injury.2020.06.019] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/23/2020] [Revised: 05/24/2020] [Accepted: 06/13/2020] [Indexed: 02/02/2023]
Abstract
BACKGROUND Malnutrition is a worldwide problem which can result in prolonged hospitalization from complications such as poor wound healing and increased morbidity. There is increasing evidence of the effect of risk of malnutrition (ROM) on outcomes in orthopedic surgical patients. However, there is little data on the effect of nutritional status on clinical outcomes in orthopedic trauma patients with surgical site infections (SSI). Therefore, our aim was to investigate how malnutrition risk affects clinical outcomes in a prospective cohort of orthopedic trauma patients with SSI. METHODS The study included 345 patients who underwent surgery due to SSI at a level 1 trauma center. All patients were evaluated on their nutritional status as assessed by the Nutritional Risk Screening in 2014/15 and 2017/18. 238 (69.0%) datasets were available for the follow-up analysis. Twenty patients (8.4%) had died, resulting in 218 patients. Outcomes investigated included comorbidities, medication intake, destination of discharge, degree of mobility, support for procuring food, mortality risk and quality of life. RESULTS 32.8% were at risk of malnutrition (ROM) at EXAM1. Female patients had a higher ROM than males (p < 0.05). Patients with ROM had more comorbidities (p < 0.001), an increased need for medication intake (p < 0.001), a decreased level of mobility (p < 0.001) and increased need of support in procuring food (p < 0.001). The destination of discharge was independent of the nutritional status (p = 0.641). Twenty (8.4%) of the available 238 patients had died during follow-up time period, resulting in a 6.2-times higher risk of mortality in patients with ROM. EQ-5D revealed that mobility, self-supply and usual activities of daily living were increased in well-nourished patients (p < 0.001). CONCLUSION ROM in orthopedic trauma patients with SSI is associated with an increased number of comorbidities and need for medication intake, a decrease in mobility and a higher dependency for food acquisition. Patients at ROM exhibited a 6.2-times higher mortality rate than well-nourished patients. EQ-5D evaluation showed better mobility, self-supply, and activity of daily living in well-nourished patients. We therefore strongly recommend supplementing patients with ROM with a specific diet during and after discharge from the hospital in order to reduce postoperative complications and long-term mortality.

Abstract
Surgical site infection (SSI) is a challenging complication after intertrochanteric fracture surgery but without a large-sample size study to investigate the incidence and risk factors of it. The present study was to investigate the incidence and risk factors of SSI after intertrochanteric fracture surgery. A total of 1941 patients underwent intertrochanteric fracture surgery between October 2014 and December 2018 were included. Demographic data, surgical variables, and preoperative laboratory indexes were obtained from a prospective database and reviewed by hospital records. The optimum cut-off value for quantitative data was detected by receiver operating characteristic analysis. The univariate analysis and multivariable analysis were conducted to analyse the risk factors. In total, 25 patients (1.3%) developed SSI, including 22(1.1%) superficial infection and 3(0.2%) deep infection. After adjustment of multiple variables, gender (odds ratio[OR] 2.64, P = .024), time to surgery>4 days (OR 2.41, P = .046), implant (intramedullary or extramedullary devices) (OR 2.96, P = .036), ALB<35 g/L (OR 2.88, P = .031) remained significant factors. In conclusion, the incidence of SSI after intertrochanteric fractures surgery was 1.3%, with 1.1% for superficial and 0.2% for deep infection. Gender, time to surgery>4 days, the implant (intramedullary or extramedullary devices), and ALB<35 g/L were independent risk factors for the rate of SSI.

[PMID: 32762762 PMCID: PMC7409683 DOI: 10.1186/s13018-020-01814-3] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/24/2020] [Accepted: 07/22/2020] [Indexed: 12/11/2022] Open
Abstract
Background Degenerative disorders of the lumbar spine decrease the mobility and quality of life of elderly patients. Lumbar fusion surgery is the primary method of treating degenerative lumbar spine disorders; however, the surgical stress response associated with major surgery has been linked to pathophysiological changes in the elderly, resulting in undesirable postoperative morbidity, complications, pain, fatigue, and extended convalescence. In the present study, we aimed to determine whether enhanced recovery after surgery significantly improved satisfaction and outcomes in elderly patients (> 65 years old) with short-level lumbar fusion. Methods The study enrolled lumbar disc herniation or lumbar spinal stenosis patients if they were over the age of 65 years old underwent lumbar fusion at one or two levels. Data including demographic, comorbidity, and surgical information were collected from electronic medical records. Enhanced recovery after surgery interventions was categorized as preoperative, intraoperative, and postoperative. We also evaluated primary outcome, surgical complication, length of stay, postoperative pain scores, and 30-day readmission rates. Results A total of 192 patients were included, 96 in the enhanced recovery after surgery group and 96 case-matched patients in the non- enhanced recovery after surgery group. There were no statistically significant intergroup differences in regards to demographics, comorbidities, American Society of Anaesthesiologists grade, or the number of fusion levels. There were also no differences between mean surgery time of intraoperative blood loss between the enhanced recovery after surgery and non- enhanced recovery after surgery groups. In addition, the mean preoperative Japanese Orthopaedic Association score, visual analog score for the back and legs, and Oswestry Disability Index score were not significantly different between the two groups. Overall, enhanced recovery after surgery pathway compliance was 92.1%. There were no significant differences in the number of complications or the mortality rates between the enhanced recovery after surgery and non-enhanced recovery after surgery groups. Furthermore, the mean postoperative Japanese Orthopaedic Association score, Visual analog score for the back and legs, Oswestry Disability Index score, and readmission rates score revealed no significant differences between the groups at 30-day follow-up point. However, we observed a statistically significant decrease in length of stay in the enhanced recovery after surgery group (12.30 ± 3.03 of enhanced recovery after surgery group versus 15.50 ± 1.88 in non- enhanced recovery after surgery group, p = 0). Multivariable linear regression showed that comorbidities (p = 0.023) and implementation of enhanced recovery after surgery program (p = 0.002) were correlated with prolonged length of stay. Multivariable logistic regression showed that no characteristics were associated with complications. Conclusions This report describes the first enhanced recovery after surgery protocol used in elderly patients after short-level lumbar fusion surgery. Our enhanced recovery after surgery program is safe and could help decrease length of stay in elderly patients with short-level lumbar fusion.
