    The Effect of Discharging Patients with Low Hemoglobin Levels on Hospital Readmission and Quality of Life after Adult Spinal Deformity Surgery
    (KOREAN SOC SPINE SURGERY, 2022-01-01) Nabi, Vugar; Ayhan, Selim; Yuksel, Selcen; Adhikari, Prashant; Vila-Casademunt, Alba; Pellise, Ferran; Perez-Grueso, Francisco Sanchez; Alanay, Ahmet; Obeid, Ibrahim; Kleinstueck, Frank; Acaroglu, Emre; Grp, European Spine Study
    Study design: Retrospective cohort. Purpose: This study aims to evaluate the impact of anemia on functional outcomes, health-related quality of life (HRQoL), and early hospital readmission (EHR) rates after adult spinal deformity (ASD) surgery at the time of discharge from the hospital. Overview of literature: Concerns with risks of transfusion, insufficient evidence for its benefits, and the possibility of associated adverse outcomes have led to restrictive transfusion practices. Therefore, patients are discharged according to patient blood management programs that are implemented in hospitals nationwide to reduce unnecessary blood transfusions. However, not many comprehensive kinds of studies exist on the effect of postoperative anemia on functional life and complications. Methods: Anemia severity was defined following the 2011 World Health Organization guidelines. All patients had HRQoL tests as well as complete blood counts pre- and postoperatively. EHR is the admission within 30 days of discharge and was used as the dependent parameter. Results: This study comprised 225 surgically treated ASD patients with a median age of 62.0 years, predominantly women (80\%). Of the 225 patients, 82, 137, and six had mild, moderate, and severe anemia at the time of discharge, respectively. Seventeen of the patients (mild {[}11, 64.7\%]

    The Influence of Diagnosis, Age, and Gender on Surgical Outcomes in Patients With Adult Spinal Deformity
    (SAGE PUBLICATIONS LTD, 2018-01-01) Ayhan, Selim; Yuksel, Selcen; Nabiyev, Vugar; Adhikari, Prashant; Villa-Casademunt, Alba; Pellise, Ferran; Sanchez Perez-Grueso, Francisco; Alanay, Ahmet; Obeid, Ibrahim; Kleinstueck, Frank; Acaroglu, Emre; Grp, European Spine Study
    Study Design: Retrospective review of prospectively collected data from a multicentric database. Objectives: To determine the clinical impact of diagnosis, age, and gender on treatment outcomes in surgically treated adult spinal deformity (ASD) patients. Methods: A total of 199 surgical patients with a minimum follow-up of 1 year were included and analyzed for baseline characteristics. Patients were separated into 2 groups based on improvement in health-related quality of life (HRQOL) parameters by minimum clinically important difference. Statistics were used to analyze the effect of diagnosis, age, and gender on outcome measurements followed by a multivariate binary logistic regression model for these results with statistical significance. Results: Age was found to affect SF-36 PCS (Short From-36 Physical Component Summary) score significantly, with an odds ratio of 1.017 (unit by unit) of improving SF-36 PCS score on multivariate analysis (P < .05). The breaking point in age for this effect was 37.5 years (AUC = 58.0, P = .05). A diagnosis of idiopathic deformity would increase the probability of improvement in Oswestry Disability Index (ODI) by a factor of 0.219 and in SF-36 PCS by 0.581 times (P < .05). Gender was found not to have a significant effect on any of the HRQOL scores. Conclusions: Age, along with a diagnosis of degenerative deformity, may have positive effects on the likelihood of improvement in SF-36 PCS (for age) and ODI (for diagnosis) in surgically treated patients with ASD and the breaking point of this effect may be earlier than generally anticipated. Gender does not seem to affect results. These may be important in patient counseling for the anticipated outcomes of surgery.

    Does the Application of Topical Intrawound Vancomycin Powder Affect Deep Surgical Site Infection and the Responsible Organisms after Spinal Surgery?: A Retrospective Case Series with a Historical Control Group
    (KOREAN SOC SPINE SURGERY, 2020-01-01) Adhikari, Prashant; Nabiyev, Vugar Nabi; Bahadir, Sinan; Ayhan, Selim; Yuksel, Selcen; Palaoglu, Selcuk; Acaroglu, Emre
    Study Design: Retrospective case series with a historical control group. Purpose: To compare the deep wound infection rates in patients undergoing spinal surgery with the application of topical intrawound vancomycin powder (TIVP) in the surgical site in addition to standard systemic prophylaxis with those in a matched historical cohort of patients for whom TIVP was not used. Overview of Literature: Surgical site infection (SSI) after spine surgery is debilitating and is responsible for a significant increase in the health care costs, hospital stay, and morbidities. Although the application of TIVP before surgical closure is a promising method for reducing the SSI rate after spine surgery, its use is controversial, and currently, research trials are focusing on identifying its safety, efficacy, and the potential patient population. Methods: A group of 88 patients who underwent posterior spinal surgery with TIVP administration (treatment group) was compared to a historical control group of 70 patients who had received only standard systemic intravenous prophylaxis (control group) for the analysis of deep SSI rate and the involved organisms. Results: The overall rate of deep SSIs was 2.5\% (4/158). All the SSIs were observed in patients who had posterior instrumentation and fusion for >= 3 levels. In the treatment group, the SSI rate was 3.4\% (3/88), and the bacteria isolated were Escherichia coli (n=2 ) and Pseudomonas aeruginosa (n=1). In the control group, the infection rate was 1.4\% (1/70), and the isolated bacteria were Morganella rnorganii and Staphylococcus epidermidis. No statistically significant association was found between the SSI rates of the treatment and control groups. Conclusions: Although the difference in the SSI rates was not statistically significant, the present results suggest that TIVP administration could not reduce the risk of deep SSIs after spinal surgery. Moreover, TIVP administration might also affect the underlying pathogens by increasing the propensity for gram-negative species.
