A Comprehensive Analysis of Tobacco Smoking History as a Risk for Outcomes after Endoscopic Transsphenoidal Resection of Pituitary Adenoma. J Neurol Surg B Skull Base 2024; 85:255-260. [PMID: 38778915 PMCID: PMC11111311 DOI: 10.1055/a-2043-0263] [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: 10/08/2022] [Accepted: 02/21/2023] [Indexed: 02/27/2023] Open
Abstract
Objectives This study seeks to comprehensively analyze the impact of smoking history on outcomes after endoscopic transsphenoidal hypophysectomy (TSH) for pituitary adenoma. Design This was a retrospective study. Setting This study was done at the tertiary care center. Participants Three hundred and ninety-eight adult patients undergoing TSH for a pituitary adenoma. Main Outcome Measures Clinical and tumor characteristics and operative factors were collected. Patients were categorized as never, former, or active smokers, and the pack-years of smoking history was collected. Years since cessation of smoking was obtained for former smokers. Specific outcomes included postoperative cerebrospinal fluid (CSF) leak, length of hospitalization, 30-day return to the operating room, and 30-day readmission. Smoking history details were comprehensively analyzed for association with outcomes. Results Any history of smoking tobacco was associated with return to the operating room (odds ratio [OR] = 2.67, 95% confidence interval [CI]: 1.05-6.76, p = 0.039), which was for persistent CSF leak in 58.3%. Among patients with postoperative CSF leak, any history of smoking was associated with need for return to the operating room to repair the CSF leak (OR = 5.25, 95% CI: 1.07-25.79, p = 0.041). Pack-years of smoking was positively associated with a return to the operating room (OR = 1.03, 95% CI: 1.01-1.06, p = 0.048). In all multivariable models, all negative outcomes were significantly associated with the covariate: occurrence of intraoperative CSF leak. Conclusion This is the first study to show smoking may have a negative impact on healing of CSF leak repairs after TSH, requiring a return to the operating room. This effect appears to be dose dependent on the smoking history. Secondarily, intraoperative CSF leak as covariate in multivariable models was significantly associated with all negative outcomes.

Int Forum Allergy Rhinol 2024; 14:613-620. [PMID: 37422726 DOI: 10.1002/alr.23237] [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: 04/12/2023] [Revised: 06/12/2023] [Accepted: 07/05/2023] [Indexed: 07/10/2023]
Abstract
BACKGROUND Readmissions are major healthcare expenditures, key hospital metrics, and are often preceded by an evaluation in the emergency department (ED). The purpose of this study was to analyze ED visits within 30 days of endoscopic skull base surgery (ESBS), risk factors for readmission once in the ED, and ED-related evaluation and outcomes. METHODS Retrospective review from January 2017 to December 2022 at a high-volume center of all ESBS patients who presented to the ED within 30 days of surgery. RESULTS Of 593 ESBS cases, 104 patients (17.5%) presented to the ED following surgery within 30 days, with a median presentation of 6 days post-discharge (IQR 5-14); 54 (51.9%) patients were discharged while 50 (48.1%) were readmitted. Readmitted patients were significantly older than discharged patients (median 60 years, IQR 50-68 vs. 48 years, 33-56; p < 0.01). Extent of ESBS was not associated with readmission or discharge from the ED. The most common discharge diagnoses were headache (n = 13, 24.1%) and epistaxis (n = 10, 18.5%); the most common readmitting diagnoses were serum abnormality (n = 15, 30.0%) and altered mental status (n = 5, 10.0%). Readmitted patients underwent significantly more laboratory testing than discharged patients (median 6, IQR 3-9 vs. 4, 1-6; p < 0.01). CONCLUSIONS Approximately half of patients who presented to the ED following ESBS were discharged home but underwent significant workup. Follow-up within 7 days of discharge, risk-stratified endocrine care pathways, and efforts to address the social determinants of health may be considered to optimize postoperative ESBS care.

BMC Health Serv Res 2024; 24:85. [PMID: 38233897 PMCID: PMC10792937 DOI: 10.1186/s12913-024-10566-3] [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: 05/09/2023] [Accepted: 01/05/2024] [Indexed: 01/19/2024] Open
Abstract
BACKGROUND The purpose of this study was to investigate differences between non-smokers, ex-smokers and current smokers in hospital length of stay (LOS), readmission (seven and 28 days) and cost of readmission for patients admitted for elective surgery. METHODS A retrospective cohort study of administrative inpatient data from 24, 818 patients admitted to seven metropolitan hospitals in Western Australia between 1 July 2016 and 30 June 2019 for multiday elective surgery was conducted. Data included smoking status, LOS, procedure type, age, sex and Indigenous status. LOS for smoking status was compared using multivariable negative binomial regression. Odds of readmission were compared for non-smokers and both ex-smokers and current smokers using separate multivariable logistic regression models. RESULTS Mean LOS for non-smokers (4.7 days, SD=5.7) was significantly lower than both ex-smokers (6.2 days SD 7.9) and current smokers (6.1 days, SD=8.2). Compared to non-smokers, current smokers and ex-smokers had significantly higher odds of readmission within seven (OR=1.29; 95% CI: 1.13, 1.47, and OR=1.37; 95% CI: 1.19, 1.59, respectively) and 28 days (OR=1.35; 95% CI: 1.23, 1.49, and OR=1.53; 95% CI: 1.39, 1.69, respectively) of discharge. The cost of readmission for seven and 28-day readmission was significantly higher for current smokers compared to non-smokers (RR=1.52; 95% CI: 1.1.6, 2.0; RR=1.39; 95% CI: 1.18, 1.65, respectively). CONCLUSION Among patients admitted for elective surgery, hospital LOS, readmission risk and readmission costs were all higher for smokers compared with non-smokers. The findings indicate that provision of smoking cessation treatment for adults undergoing elective surgery is likely to produce multiple benefits.

Discontinuation of Postoperative Prophylactic Antibiotics for Endoscopic Endonasal Skull Base Surgery. J Neurol Surg B Skull Base 2023; 84:157-163. [PMID: 36895810 PMCID: PMC9991524 DOI: 10.1055/a-1771-0372] [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: 07/16/2021] [Accepted: 01/24/2022] [Indexed: 10/19/2022] Open
Abstract
Background Postoperative prophylactic antibiotic usage for endoscopic skull base surgery varies based on the institution as evidence-based guidelines are lacking. The purpose of this study is to determine whether discontinuing postoperative prophylactic antibiotics in endoscopic endonasal cases led to a difference in central nervous system (CNS) infections, multi-drug resistant organism (MDRO) infections, or other postoperative infections. Methods This quality improvement study compared outcomes between a retrospective cohort (from September 2013 to March 2019) and a prospective cohort (April 2019 to June 2019) after adopting a protocol to discontinue prophylactic postoperative antibiotics in patients who underwent endoscopic endonasal approaches (EEAs). Our primary end points of the study included the presence of postoperative CNS infection, Clostridium difficile ( C. diff ), and MDRO infections. Results A total of 388 patients were analyzed, 313 in the pre-protocol group and 75 in the post-protocol group. There were similar rates of intraoperative cerebrospinal fluid leak (56.9 vs. 61.3%, p = 0.946). There was a statistically significant decrease in the proportion of patients receiving IV antibiotics during their postoperative course ( p = 0.001) and those discharged on antibiotics ( p = 0.001). There was no significant increase in the rate of CNS infections in the post-protocol group despite the discontinuation of postoperative antibiotics (3.5 vs. 2.7%, p = 0.714). There was no statistically significant difference in postoperative C. diff (0 vs. 0%, p = 0.488) or development of MDRO infections (0.3 vs 0%, p = 0.624). Conclusion Discontinuation of postoperative antibiotics after EEA at our institution did not change the frequency of CNS infections. It appears that discontinuation of antibiotics after EEA is safe.

Endoscopic Reconstruction of the Anterior Skull Base Following Tumor Resection: Application of a Novel Bioabsorbable Plate. Laryngoscope 2022; 133:1092-1098. [PMID: 36477852 DOI: 10.1002/lary.30501] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2022] [Revised: 10/30/2022] [Accepted: 11/18/2022] [Indexed: 12/12/2022]
Abstract
OBJECTIVE Endoscopic repair of skull base defects is required following resection of intracranial pathology via the endoscopic endonasal approach (EEA). Many closure techniques have been described, but choosing between techniques remains controversial. We report outcomes of 560 EEA procedures of skull base reconstruction performed on 508 patients over a 15-year-period. Halfway through this period, we adopted the use of a rigid, bioabsorbable extrasellar plate for reconstruction, enabling a comparison between this technique and those used previously. METHODS All patients undergoing EEA from 2005 to 2019 at our institution were retrospectively reviewed. Demographic information, surgical pathology, tumor dimensions and radiographic features, reconstructive technique, and patient-related outcomes were collected and analyzed with univariate and multivariate statistical modeling. RESULTS Five-hundred sixty procedures were performed on 508 patients. The series complication rate was 8.2%. Overall, cerebrospinal fluid (CSF) leak rate was 5.0% but varied significantly across closure techniques (p < 0.001). Critically, the CSF leak rate in the 272 cases prior to our 2013 adoption of the Resorb-X Plate (RXP) was 8.5%, whereas leak rate in the subsequent 288 cases was 1.7%. RXP was protective against CSF leak (p = 0.001), whereas gross total resection (GTR) correlated with increased leak rate (p = 0.001). Patient BMI was significantly associated with risk of leak (p = 0.047). Other variables did not impact leak risk. CONCLUSION Reconstructive technique, extent of resection, and patient BMI significantly contributed to CSF leak rate. GTR was associated with increased leak risk while the RXP was protective. The bioabsorbable RXP is an effective option for rigid skull base repair with comparatively few complications. LEVEL OF EVIDENCE 3 Laryngoscope, 133:1092-1098, 2023.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVE To assess readmission rates and risk factors for 30-day and 90-day readmission after elective lumbar decompression at a single institution. SUMMARY OF BACKGROUND DATA Hospital readmission is an undesirable aspect of interventional treatment. Studies evaluating readmissions after elective lumbar decompression typically analyze national databases, and therefore have several drawbacks inherent to their macroscopic nature that limit their clinical utility. METHODS Patients undergoing primary one- to four-level lumbar decompression surgery were retrospectively identified. Demographic, surgical, and readmission data within "30-days" (0-30 days) and "90-days" (31-90 days) postoperatively were extracted from electronic medical records. Patients were categorized into four groups: (1) no readmission, (2) readmission during the 30-day or 90-day postoperative period, (3) complication related to surgery, and (4) Emergency Department (ED)/Observational (OBs)/Urgent (UC) care. RESULTS A total of 2635 patients were included. Seventy-six (2.9%) were readmitted at some point within the 30- (2.3%) or 90-day (0.3%) postoperative periods. Patients in the pooled readmitted group were older (63.1 yr, P < 0.001), had a higher American Society of Anesthesiologists (ASA) grade (31.2% with ASA of 3, P = 0.03), and more often had liver disease (8.1%, P = 0.004) or rheumatoid arthritis (12.0%, P = 0.02) than other cohorts. A greater proportion of 90-day readmissions and complications had surgical-related diagnoses or a diagnosis of recurrent disc herniation than 30-day readmissions and complications (66.7% vs. 44.5%, P = 0.04 and 33.3% vs. 5.5%, P < 0.001, respectively). Age (Odds ratio [OR]: 1.02, P = 0.01), current smoking status (OR: 2.38, P < 0.001), longer length of stay (OR: 1.14, P < 0.001), and a history of renal failure (OR: 2.59, P = 0.03) were independently associated with readmission or complication. CONCLUSION Increased age, current smoking status, hospital length of stay, and a history of renal failure were found to be significant independent predictors of inpatient readmission or complication after lumbar decompression.

Abstract
BACKGROUND Many techniques have been utilized for reconstruction of the anterior skull base. Each method has advantages and disadvantages with respect to effectiveness, morbidity, strength, and cost. Rigid reconstruction may provide advantages in certain patients. OBJECTIVE We evaluated all patients who had placement of rigid absorbable reconstruction plates in the anterior skull base in a variety of extrasellar locations and describe results and complications compared with other published techniques. METHODS A retrospective review was conducted of consecutive patients at a tertiary referral institution who underwent endoscopic extrasellar skull base reconstruction, 2012-2019, using resorbable poly (D,L) lactic acid plates (Resorb-X Sellar Wall Plate; KLS Martin; Jacksonville, FL). Data reviewed included demographic information, indication for surgery, location and size of defect, pathology, peri-operative use of cerebrospinal fluid (CSF) diversion, postoperative complications, post-operative CSF leak, adjuvant therapy, and length of follow-up. RESULTS Twenty-four subjects and 25 operative procedures met inclusion criteria. Mean age was 53 years (range 11-77). Average BMI was 34 kg/m2. Mean follow-up time was 30 months (range 1-78). Indications for surgery were CSF rhinorrhea (spontaneous, post-traumatic, or iatrogenic) or reconstruction after tumor resection. Four cases were revision procedures. Twenty patients had lumbar drains placed intraoperatively. Only two nasoseptal flaps and two free mucosal grafts were used. None of the patients had a postoperative CSF leak. There was no mortality or morbidity related to the skull base reconstruction or implanted material. CONCLUSION The Resorb-X resorbable rigid plate provides an effective, customizable, bioabsorbable option that is easily manipulated for skull base reconstruction of defects of a variety of sizes in diverse locations. Reconstruction incorporating this plate provides an effective alternative to other previously described techniques.
