Significant perioperative parameters affecting postoperative complications within 30 days following craniotomy for primary malignant brain tumors. Perioper Med (Lond) 2023; 12:54. [PMID: 37872604 PMCID: PMC10594926 DOI: 10.1186/s13741-023-00343-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2022] [Accepted: 10/02/2023] [Indexed: 10/25/2023] Open
Abstract
BACKGROUND The occurrence of postoperative complications within 30 days (PC1M) of a craniotomy for the removal of a primary malignant brain tumor has been associated with a poor prognosis. However, it is still unclear to early predict the occurrence of PC1M. This study aimed to identify the potential perioperative predictors of PC1M from its preoperative, intraoperative, and 24-h postoperative parameters. METHODS Patients who had undergone craniotomy for primary malignant brain tumor (World Health Organization grades III and IV) from January 2011 to December 2020 were enrolled from a databank of Kaohsiung Veterans General Hospital, Taiwan. The patients were classified into PC1M and nonPC1M groups. PC1M was defined according to the classification by Landriel et al. as any deviation from an uneventful 30-day postoperative course. In both groups, data regarding the baseline characteristics and perioperative parameters of the patients, including a new marker-kinetic estimated glomerular filtration rate, were collected. Logistic regression was used to analyze the predictability of the perioperative parameters. RESULTS The PC1M group included 41 of 95 patients. An American Society of Anesthesiologists score of > 2 (aOR, 3.17; 95% confidence interval [CI], 1.19-8.45; p = 0.021), longer anesthesia duration (aOR, 1.16; 95% CI, 0.69-0.88; p < 0.001), 24-h postoperative change in hematocrit by > - 4.8% (aOR, 3.45; 95% CI, 1.22-9.73; p = 0.0019), and 24-h postoperative change in kinetic estimated glomerular filtration rate of < 0 mL/min (aOR, 3.99; 95% CI, 1.52-10.53; p = 0.005) were identified as independent risk factors for PC1M via stepwise logistic regression analysis. When stratified according to the age of ≥ 65 years (OR, 11.55; 95% CI, 1.30-102.79; p = 0.028), the reduction of kinetic estimated glomerular filtration rate was more robustly associated with a higher risk of PC1M. CONCLUSIONS Four parameters were demonstrated to significantly influence the risk of PC1M in patients undergoing primary malignant brain tumor removal. Measuring and verifying these markers, especially kinetic estimated glomerular filtration rate, would help early recognition of PC1M risk in clinical care.

Abstract
Radiation-induced acute and late toxicity depends on several parameters. The type, severity and duration of morbidity are mainly related to irradiated volume, total dose and its fractionation and the intrinsic radiosensitivity of the patients. The follow-up of these toxicities is essential. However, unlike many specialties, morbidity and mortality reviews procedures are not developed as part of quality governance programs in radiation therapy departments for the monitoring of toxicity which sometimes hinder the patients' quality of life. One French survey published within the framework of the project entitled Prospective Registration of Morbidity and Mortality, Individual Radiosensitivity and Radiation Technique (Proust), conclude that there was a lack of knowledge of morbidity and mortality reviews and considerable confusion between these reviews and other quality processes without perspective for the local morbidity and mortality reviews development in a large number of the participated centers. In this article, we will discuss the procedure of the "ideal morbidity and mortality reviews" and its implementation through a monocentric experience started in 2015. Thus, the Proust project is a unique opportunity to implement and standardize a national morbidity and mortality reviews implementation in radiation therapy departments by involving the French regions.

Abstract
BACKGROUND Quality measurement and outcome assessment have recently caught an attention of the neurosurgical community, but lack of standardized definitions and methodology significantly complicates these tasks. OBJECTIVE To identify a uniform definition of neurosurgical complications, to classify them according to etiology, and to evaluate them comprehensively in cases of intracranial tumor removal in order to establish a new, easy, and practical grading system capable of predicting the risk of postoperative clinical worsening of the patient condition. METHODS A retrospective analysis was conducted on all elective surgeries directed at removal of intracranial tumor in the authors' institution during 2-year study period. All sociodemographic, clinical, and surgical factors were extracted from prospectively compiled comprehensive patient registry. Data on all complications, defined as any deviation from the ideal postoperative course occurring within 30 days of the procedure, were collected with consideration of the required treatment and etiology. A logistic regression model was created for identification of independent factors associated with worsening of the Karnofsky Performance Scale (KPS) score at discharge after surgery in comparison with preoperative period. For each identified statistically significant independent predictor of the postoperative worsening, corresponding score was defined, and grading system, subsequently named Milan Complexity Scale (MCS), was formed. RESULTS Overall, 746 cases of surgeries for removal of intracranial tumor were analyzed. Postoperative complications of any kind were observed in 311 patients (41.7%). In 223 cases (29.9%), worsening of the KPS score at the time of discharge in comparison with preoperative period was noted. It was independently associated with 5 predictive factors-major brain vessel manipulation, surgery in the posterior fossa, cranial nerve manipulation, surgery in the eloquent area, tumor size >4 cm-which comprised MCS with a range of the total score from 0 to 8 (higher score indicates more complex clinical situations). Patients who demonstrated KPS worsening after surgery had significantly higher total MCS scores in comparison with individuals whose clinical status at discharge was improved or unchanged (3.24 ± 1.55 versus 1.47 ± 1.58; P < 0.001). CONCLUSION It is reasonable to define neurosurgical complication as any deviation from the ideal postoperative course occurring within 30 days of the procedure. Suggested MCS allows for standardized assessment of surgical complexity before intervention and for estimating the risk of clinical worsening after removal of intracranial tumor. Collection of data on surgical complexity, occurrence of complications, and postoperative outcomes, using standardized prospectively maintained comprehensive patient registries seems very important for quality measurement and should be attained in all neurosurgical centers.

Abstract
BACKGROUND The most widely used classifications of adverse events (AEs) in neurosurgery define their severity according to the therapy used to treat them. This concept has substantial shortcomings because it does not reflect the severity of AEs that are not treated, such as new neurological deficits. OBJECTIVE To present a novel multidimensional and patient-centered classification of the severity of AE in neurosurgery and evaluate its applicability. METHODS The Therapy-Disability-Neurology (TDN) grading system classifies AEs depending on the associated therapy, disability, and neurological deficits. We conducted a 2-center retrospective observational study on 6071 interventions covering the whole neurosurgical spectrum with data prospectively recorded between 2013 and 2019 at 2 institutions from 2 countries. RESULTS Using the first patient cohort (4680 interventions), a positive correlation was found between severity of AE and LOS as well as treatment cost. Each grade was associated with a greater deterioration of the Karnofsky Performance Status Scale (KPS) at discharge and at follow-up. When using the same methods on the external validation cohort (1391 interventions), correlations between the grades of AE, LOS, and KPS at discharge were even more pronounced. CONCLUSION Our results suggest that the TDN grade is consistent with clinical and economic repercussions of AE and thus reflects AE severity. It is easily interpreted and enables comparison between different medical centers. The standardized report of the severity of AE in the scientific literature could constitute an important step forward toward a more critical, patient-centered, and evidence-based decision-making in neurosurgery.

Abstract
OBJECTIVE The absence of a commonly accepted standardized classification system for complication reporting confounds the recognition, objective reporting, management, and avoidance of perioperative adverse events. In the past decade, several classification systems have been proposed for use in neurosurgery, but these generally focus on tallying specific complications and grading their effect on patient morbidity. Herein, the authors propose and prospectively validate a new neurosurgical complication classification based on understanding the underlying causes of the adverse events. METHODS A new complication classification system was devised based on the authors' previous work on morbidity in endovascular surgery. Adverse events were prospectively compiled for all neurosurgical procedures performed at their tertiary care academic medical center over the course of 1 year into 5 subgroups: 1) indication errors; 2) procedural errors; 3) technical errors; 4) judgment errors; and 5) critical events. The complications were presented at the monthly institutional Morbidity and Mortality conference where, following extensive discussion, they were assigned to one of the 5 subgroups. Additional subgroup analyses by neurosurgical subspecialty were also performed. RESULTS A total of 115 neurosurgical complications were observed and analyzed during the study period. Of these, nearly half were critical events, while technical errors accounted for approximately one-third of all complications. Within neurosurgical subspecialties, vascular neurosurgery (36.5%) had the most complications, followed by spine & peripheral nerve (21.7%), neuro-oncology (14.8%), cranial trauma (13.9%), general neurosurgery (12.2%), and functional neurosurgery (0.9%). CONCLUSIONS The authors' novel neurosurgical complication classification system was successfully implemented in a prospective manner at their high-volume tertiary medical center. By employing the well-established Morbidity and Mortality conference mechanism, this simple system may be easily applied at other neurosurgical centers and may allow for uniform analyses of perioperative morbidity and the introduction of corrective initiatives.

Abstract
OBJECTIVE To investigate predictors of recurrence and moderate to severe complications after burr-hole surgery for chronic subdural hematoma (cSDH). METHODS A retrospective review was conducted in a Scandinavian single-center population-based cohort of 759 adult patients with cSDH operated with burr-hole surgery between January 1, 2005 and December 31, 2010. Possible predictors of recurrence and complications, assessed using a standardized reporting system of adverse events, were identified and analyzed in univariable analyses. Variables with a P value < 0.10 were included in a multivariable regression model. RESULTS Recurrence was observed in 85 patients (11.2%), whereas moderate to severe complications were observed in 35 patients (4.6%). Bilateral hematoma (odds ratio [OR], 2.05; 95% confidence interval [CI], 1.25-3.35; P < 0.01) and largest hematoma diameter in millimeters (OR, 1.05; 95% CI, 1.01-1.09; P < 0.01) were independent predictors of recurrence in the multivariable model analysis. Glasgow Coma Scale (GCS) score of <13 (OR, 6.06; 95% CI, 2.72-13.51; P < 0.01) and Charlson Comorbidity Index (CCI) >1 (OR, 2.28; 95% CI, 1.10-4.75; P = 0.03) were independent predictors of moderate to severe complications. CONCLUSIONS Recurrence after cSDH surgery is more often encountered in patients with radiologically more extensive disease reflected by bilateral hematoma and large hematoma diameter. On the other hand, moderate to severe complications are more often seen in patients in a worse clinical condition, reflected by decreased level of consciousness and more comorbidities.

Abstract
Background To improve the transparency of the local health care system, treatment cost was recently referenced to disease related groups. Treatment quality must be legally documented in a patient registry, in particular for the highly specialized treatments provided by neurosurgery departments. Methods In 2013 we have installed a patient registry focused on cranial neurosurgery. Surgeries are characterized by indication, treatment, location and other specific neurosurgical parameters. Preoperative state and postoperative outcome are recorded prospectively using neurological and sociological scales. Complications are graded by their severity in a therapy-oriented complication score system (Clavien-Dindo-Grading system, CDG). Results are presented at the monthly clinical staff meeting. Results Data acquisition compatible with the clinic workflow permitted to include all eligible patients into the registry. Until December 2015, we have registered 2880 patients that were treated in 3959 surgeries and 8528 consultations. Since the registry is fully operational (August 2014), we have registered 325 complications on 1341 patient discharge forms (24%). In 64% of these complications, no or only pharmacological treatment was required. At discharge, there was a clear correlation of the severity of the complication and the Karnofsky Performance Status (KPS, ρ = -0.3, slope -6 KPS percentage points per increment of CDG) and the length of stay (ρ = 0.4, slope 1.5 days per increment of CDG). Conclusions While the therapy-oriented complication scores correlate reasonably well with outcome and length of stay, they do not account for new deficits that cannot be treated. Outcome grading and complication severity grading thus serve a complimentary purpose. Overall, the registry serves to streamline and to complete information flow in the clinic, to identify complication rates and trends early for the internal quality monitoring and communication with patients. Conversely, the registry influences clinical practice in that it demands rigorous documentation and standard operating procedures.

Abstract
OBJECT
The Milan Complexity Scale—a new practical grading scale designed to estimate the risk of neurological clinical worsening after performing surgery for tumor removal—is presented.
METHODS
A retrospective study was conducted on all elective consecutive surgical procedures for tumor resection between January 2012 and December 2014 at the Second Division of Neurosurgery at Fondazione IRCCS Istituto Neurologico Carlo Besta of Milan. A prospective database dedicated to reporting complications and all clinical and radiological data was retrospectively reviewed. The Karnofsky Performance Scale (KPS) was used to classify each patient’s health status. Complications were divided into major and minor and recorded based on etiology and required treatment. A logistic regression model was used to identify possible predictors of clinical worsening after surgery in terms of changes between the preoperative and discharge KPS scores. Statistically significant predictors were rated based on their odds ratios in order to build an ad hoc complexity scale. For each patient, a corresponding total score was calculated, and ANOVA was performed to compare the mean total scores between the improved/unchanged and worsened patients. Relative risk (RR) and chi-square statistics were employed to provide the risk of worsening after surgery for each total score.
RESULTS
The case series was composed of 746 patients (53.2% female; mean age 51.3 ± 17.1). The most common tumors were meningiomas (28.6%) and glioblastomas (24.1%). The mortality rate was 0.94%, the major complication rate was 9.1%, and the minor complication rate was 32.6%. Of 746 patients, 523 (70.1%) patients improved or remained unchanged, and 223 (29.9%) patients worsened. The following factors were found to be statistically significant predictors of the change in KPS scores: tumor size larger than 4 cm, cranial nerve manipulation, major brain vessel manipulation, posterior fossa location, and eloquent area involvement (Nagelkerke R2 = 0.286). A grading scale was obtained with scores ranging between 0 and 8. Worsened patients showed mean total scores that were significantly higher than the improved/unchanged scores (3.24 ± 1.55 vs 1.47 ± 1.58; p < 0.001). Finally, a grid was developed to show the risk of worsening after surgery for each total score: scores higher than 3 are suggestive of worse clinical outcome.
CONCLUSIONS
Through the evaluation of the 5 aforementioned parameters—the Big Five—the Milan Complexity Scale enables neurosurgeons to estimate the risk of a negative clinical course after brain tumor surgery and share these data with the patient. Furthermore, the Milan Complexity Scale could be used for research and educational purposes and better health system management.

Abstract
OBJECT The authors conducted a study to compare the complication rate (CR) of pediatric neurosurgical procedures in a general neurosurgery department to the CRs that are reported in the literature and to establish a baseline of CR for further targeted improvement of quality neurosurgical care. METHODS The authors analyzed the prospectively collected data from a complication registration of 1000 consecutive pediatric neurosurgical procedures in 581 patients from the beginning of the registration in January 2004 through August 2008. A pediatric neurosurgeon was involved in 50.5% of the procedures. All adverse events (AEs) from induction of anesthesia until 30 days postoperatively were recorded. RESULTS Overall, 229 complications were counted in 202 procedures. The overall CR was 20.2%, with a 2.7% intraoperative CR and a 17.5% postoperative CR. Tumor surgery was associated with the highest CR (32.7%), followed by CSF disorders (21.8%). The mortality rate was 0.3%. An unplanned return to the operating room in relation to an AE happened in 10.5% of all procedures and in 52% of procedures associated with AEs, the majority of which were related to CSF disorders. CONCLUSIONS The CR in pediatric neurosurgical procedures was significant, and more than half of the patients with an AE required a repeat surgical procedure. Analysis of CRs should be a prerequisite for the prevention of complications and for the development of targeted interventions to reduce the CR (for example, infection rates).

Abstract
BACKGROUND The incidence of surgical site infections (SSI) is considered increasingly to be an indicator of quality of care. We conducted a study in which daily inspection of the surgical incision was performed by an independent, trained team to monitor the incidence of SSI using U.S. Centers for Disease Control and Prevention (CDC) definitions, as a gold-standard measure of care. In the department of surgery, two registration systems for SSI were used routinely by the surgeon: An electronic and a plenary tracking system. The results of the independent team were compared with the outcomes provided by two registration systems for SSI, so as to evaluate the reliability of these systems as a possible alternative for indicating quality of care. METHODS The study was an incidence study conducted from May 2007 to January 2009 that included 1,000 adult patients scheduled to undergo open abdominal surgery in an academic teaching hospital. Surgical incisions were inspected daily to check for SSI according to definitions of health care-associated infections established by the CDC. Follow-up after discharge was done at the outpatient clinic of the hospital by telephone or letter in combination with patient diaries and reviews of patient charts, discharge letters, electronic files, and reported complications. Univariate and multivariable analyses were done to identify putative risk factors for missing registrations. RESULTS Of the 1,000 patients in the study, 33 were not evaluated. Surgical site infections were diagnosed in 26.8% of the 967 remaining patients, of which 18.0% were superficial incisional infections, 5.4% were deep incisional infections, and 3.4% were organ/space infections. More than 60% of SSIs were unreported in either of the department's two tracking systems for such infections. For these two systems, independent major risk factors for missing registrations were (1) the lack of occurrence of an SSI, (2) transplantation surgery, and (3) admission to non-surgical departments. CONCLUSIONS Most SSIs were not tracked with the department's two systems. These systems proved poor alternatives to the gold-standard method of quantifying the incidence of Surgical Site Infection SSI and, therefore, the quality of care. Both protocolized wound assessment and on-site documentation are mandatory for realistic quantification of the incidence of SSI.

Abstract
OBJECTIVE To define and grade neurosurgical and spinal postoperative complications based on their need for treatment. METHODS Complications were defined as any deviation from the normal postoperative course occurring within 30 days of surgery. A four-grade scale was proposed based on the therapy used to treat the complications: grade I, any non-life-threatening complications treated without invasive procedures; grade II, complications requiring invasive management such as surgical, endoscopic, and endovascular procedures; grade III, life-threatening adverse events requiring treatment in an intensive care unit (ICU); and grade IV, deaths as a result of complications. Each grade was classified as a surgical or medical complication. An observational test of this system was conducted between January 2008 and December 2009 in a cohort of 1190 patients at the Hospital Italiano de Buenos Aires. RESULTS Of 167 complications, 129 (10.84%) were classified as surgical, and 38 (3.19%) were classified as medical complications. Grade I (mild) complications accounted for 31.73%, grade II (moderate) complications accounted for 25.74%, and grade III (severe) complications accounted for 34.13%. The overall mortality rate was 1.17%; 0.84% of deaths were directly related to surgical procedures. CONCLUSIONS The authors present a simple, practical, and easy to reproduce way to report negative outcomes based on the therapy administered to treat a complication. The main advantages of this classification are the ability to compare surgical results among different centers and times, the ability to compare medical and surgical complications, and the ability to perform future meta-analyses.

Abstract
OBJECTIVE Morbidity and mortality conferences (M&MC) are a traditional part of residency programs in a large number of countries to increase the training quality. The purpose of the present publication is to report our experience with a monthly M&MC over a 5-year period and, in particular, to describe the methods to identify critical cases, the system of analysis, classification of morbidity and mortality, and the resulted impact. METHOD Monthly identification of M&M was done through a system of electronically coding hospital course at the time of discharge. Morbidity was classified as moderate if sequels resolved within 3 months or otherwise as severe. Morbidity included management complications not directly related the neurosurgical procedure, such as pneumonia or thromboembolism. Mortality was classified as related to surgery or unrelated, e.g., after severe trauma. Mortality in relation to surgery was subclassified in terms of causal relation or not. Statistical comparison of incidence rates was calculated statistically. RESULTS Overall management morbidity rate was 7.1%, and mortality with causal relation to surgery was 0.38%. The leading cause of morbidity was additional neurological deficit (25%) followed by postoperative hemorrhage (23%) and second unplanned surgery due to incomplete result of the primary procedure (14%). Overall, the monthly incidence varied without a discernable annual pattern. Over the years, there were only a handful of guideline updates triggered by incidents. CONCLUSION Our system to identify complication proved to be reliable. During the study period, the M&MC developed into a well-accepted instrument of quality control and problem-oriented teaching, but the impact on quality improvement remained questionable.

Abstract
Physicians and other health-care professionals are rapidly adopting personal digital assistants (PDA). Palm pilots and other hand-held computers are also increasingly popular among medical students. PDAs can be used for medical student education and physician training, daily clinical practice, and research. PDAs and their increasing integration with information technology in hospitals could change the way health care is delivered in the future. But despite the increasing use of PDAs, evidence from well-designed research studies is still needed to show how much these devices can improve the quality of care, save patients' lives, and ultimately reduce health-care expenses. In this Review of PDA use in health care, the operating systems, basic functionality, security and safety, limitations, and future implications of PDAs are examined. A personal perspective and an introduction to medical PDA applications, software, guidelines, and programmes for health-care professionals is also provided.

Abstract
BACKGROUND The study was undertaken in order to assess the degree of concordance between the patient's and surgeon's perceptions of adverse events after groin hernia surgery. METHODS 206 patients who underwent elective surgery for groin hernia at Samariterhemmet, Uppsala, Sweden in 2003 were invited to a follow-up visit after 3-6 weeks. At this visit the patient was instructed to answer a questionnaire including 12 questions concerning postoperative complications. A postoperative history was taken and a clinical examination performed by a surgeon who was not present at the operation and did not know the outcome of the questionnaire. All complications noted by the physician were recorded for corresponding questions in the questionnaire. RESULTS 174 (84.5%) patients attended the follow up, 161 men and 13 women. A total of 190 complications were revealed by the questionnaire, 32 of which had caused the patient to seek help from the health-care system. There were 131 complications registered as a result of the follow-up clinical examinations and history. Kappa levels ranged from 0.11 for urinary complications to 0.56 for constipation. CONCLUSION In general, the concordance was poor. These results emphasise the importance of providing detailed information about the usual postoperative course prior to the operation. Whereas the surgeon, from a professional point of view, has a better idea about what should be expected in the postoperative period and how any complications should be categorised, only the patient has a complete picture of the symptoms and adverse events. This makes it impossible to reach complete agreement between the patient's and surgeon's perceptions of complications, even under the most ideal circumstances.

Abstract
It is strongly recommended that general guidelines and internal regulations be laid down in written form by the department. The guidelines regulate the general workflow and related trainee duties and responsibilities, education and research, special procedures for particular diseases and conditions (standards of care). Regarding general workflow of the department, the following items should be laid down once in written form: time table of department, working hours, admission procedures, medical records directives, responsibilities on wards and in the emergency unit, patient information, discharge procedures, outpatient consultations, call schedule and on-call duty plan, as well as week-end and holiday regulations for rounds on wards and ICU. Regarding education and research, the following items should be written down: conferences and teaching rounds, policies on presentations and publications, policies regarding meetings and courses, research leave and vacation plan. The written definition of standards of care is still considered optional in neurosurgery at the present time.
