The effect of a bundle intervention for ambulatory otorhinolaryngology procedures on same-day case cancellation rate and associated costs.

Cancellations within 24 h of planned elective surgical procedures reduce operating theatre efficiency, add unnecessary costs and negatively affect patient experience. We implemented a bundle intervention that aimed to reduce same-day case cancellations. This consisted of communication tools to improve patient engagement and new screening instruments (automated estimation of ASA physical status and case cancellation risk score plus four screening questions) to identify patients in advance (ideally before case booking) who needed comprehensive pre-operative risk stratification. We studied patients scheduled for ambulatory surgery with the otorhinolaryngology service at a single centre from April 2021 to December 2022. Multivariable logistic regression and interrupted time-series analyses were used to analyse the effects of this intervention on case cancellations within 24 h and costs. We analysed 1548 consecutive scheduled cases. Cancellation within 24 h occurred in 114 of 929 (12.3%) cases pre-intervention and 52 of 619 (8.4%) cases post-intervention. The cancellation rate decreased by 2.7% (95%CI 1.6-3.7%, p < 0.01) during the first month, followed by a monthly decrease of 0.2% (95%CI 0.1-0.4%, p < 0.01). This resulted in an estimated $150,200 (£118,755; €138,370) or 35.3% cost saving (p < 0.01). Median (IQR [range]) number of days between case scheduling and day of surgery decreased from 34 (21-61 [0-288]) pre-intervention to 31 (20-51 [1-250]) post-intervention (p < 0.01). Patient engagement via the electronic health record patient portal or text messaging increased from 75.9% at baseline to 90.8% (p < 0.01) post-intervention. The primary reason for case cancellation was patients' missed appointment on the day of surgery, which decreased from 7.2% pre-intervention to 4.5% post-intervention (p = 0.03). An anaesthetist-driven, clinical informatics-based bundle intervention decreases same-day case cancellation rate and associated costs in patients scheduled for ambulatory otorhinolaryngology surgery.

Trans-hyoid hyoidthyroidpexy: A modified technique for selected cases of obstructive sleep apnea.

OBJECTIVE: Hypopharyngeal collapse (HC) considered a challenge in surgery of obstructive sleep apnea (OSA). Several procedures were presented to deal with HC indirectly via providing support to the lateral walls of the hypopharynx preventing transverse collapse but hyoidthryoidpexy had gained more popularity. The procedure aimed to fix the mobile hyoid bone to a rigid mid-line neck structure, thus preventing the bone and its attached muscles from collapsing during sleep with the negative intrathoracic pressure on inspiration. STUDY DESIGN: A prospective case series study. METHODS: From April 2018 to January 2020, A Modified Technique of Trans hyoid hyoidthyroidpexy was applied for all included patients (24) patients with symptoms of OSA showing predominant lateral wall collapse of the hypopharynx (with retro-palatal collapse) with other OSA surgery. RESULTS: 6-8 months postoperatively, the Apnea Hypopnea index dropped from 43.75 ± 8.44 to 16.28 ± 7.35 (P < 0.0001; t = 10.6988). 14 patients (58.33%) were reported as successful while 7 patients (29.17%) were considered responders and three patients (12.5%) were considered non responders. The mean lowest oxygen desaturation elevated from 77.56 ± 5.64 to 92.38 ± 6.25 (p < 0.0001). Epworth Sleepiness Scale improved (P < 0.0001) from 16.85 ± 4.23 to 5.17 ± 3.89. CONCLUSION: Trans-hyoid hyoidthyroidpwxy is a modified technique of hyoidthyroidpexy. The procedure reported good outcomes in treating OSA. It is a simple, cost-effective and less traumatic technique. It could be combined with other multilevel surgical procedures.

Robot-assisted sialolithotomy with sialoendoscopy: a review of safety, efficacy and cost.

OBJECTIVE: Review the safety, efficacy and cost of robot-assisted sialolithotomy with sialoendoscopy (RASS) for large submandibular gland hilar sialoliths. STUDY DESIGN: Retrospective case series. METHODS: Patients ≥18 years diagnosed with submandibular hilar sialolithiasis between 1/1/2015 and 7/31/2018 who underwent RASS were identified. Procedure success, post-operative complications, procedure duration, and costs associated with the procedure were reviewed. RESULTS: 33 patients fit inclusion criteria. 94% of patients had successful sialolith removal. Mean sialolith size was 8.9 mm. 15.1% had transient tongue paresthesia. 0% had permanent tongue paresthesia compared to a 2% rate of lingual nerve damage cited in the literature for combined approach sialolithotomy (CAS). The average total cost was $16,921. Insurance paid 100%, 90-99%, 70-89.9%, and 40-69.9% of the expected reimbursement in 43.8%, 18.7%, 18.7% and 12.5% of patients respectively. 6% of patients self-paid. Compared to CAS, the cost of reusable robotic arms and drapes totaled $475, though these costs were included in the standardized operative cost per minute and were not forwarded to the patient. The mean procedure time was 62 minutes. Compared to published mean procedure times for CAS, the reduced operative time may account for a savings of $3332-$6069. CONCLUSION: RASS is a safe modality for submandibular hilar sialolith removal with a high success rate, low risk for temporary tongue paresthesia, and lower rate of permeant lingual nerve damage compared to CAS. Compared with CAS, RASS may result in a net reduction of operative room costs given its shorter procedure time.

Recurrent Respiratory Papillomatosis Office versus Operating Room: Systematic Review and Meta-Analysis.

OBJECTIVES: Recurrent respiratory papillomatosis can be treated in the office or operating room (OR). The choice of treatment is based on several factors, including patient and surgeon preference. However, there is little data to guide the decision-making. This study examines the available literature comparing operative treatment in-office versus OR. METHODS: A systematic review was performed following Preferred Reporting Items for Systematic Reviews guidelines. Of 2,864 articles identified, 78 were reviewed full-length and 18 were included. Outcomes of interest were recurrence and complication rates, number of procedures, time interval between procedures, and cost. RESULTS: Only one study compared outcomes of operative in-office to OR treatments. The weighted average complication rate for OR procedures was 0.02 (95% confidence interval [CI] 0.00-0.32), n = 8, and for office procedures, 0.17 (95% CI 0.08-0.33), n = 6. The weighted average time interval between OR procedures was 10.59 months (5.83, 15.35) and for office procedures 5.40 months (3.26-7.54), n = 1. The weighted average cost of OR procedures was $10,105.22 ($5,622.51-14,587.83), n = 2 versus $2,081.00 ($1,987.64-$2,174.36), n = 1 for office procedures. CONCLUSION: Only one study compares office to OR treatment. The overall data indicate no differences aside from cost and imply that office procedures may be more cost-effective than OR procedures. However, the heterogeneous data limits any strong comparison of outcomes between office and OR-based treatment of laryngeal papillomas. More studies to compare the two treatment settings are warranted.

Decision Modeling for Economic Evaluation in Otolaryngology-Head and Neck Surgery: Review of Techniques.

Decision making in health care is complex, and substantial uncertainty can be involved. Structured, systematic approaches to the integration of available evidence, assessment of uncertainty, and determination of choice are of significant benefit in an era of "value-based care." This is especially true for otolaryngology-head and neck surgery, where technological advancements are frequent and applicable to an array of subspecialties. Decision analysis aims to achieve these goals through various modeling techniques, including (1) decision trees, (2) Markov process, (3) microsimulation, and (4) discrete event simulation. While decision models have been used for decades, many clinicians and researchers continue to have difficulty deciphering them. In this review, we present an overview of various decision analysis modeling techniques, their purposes, how they can be interpreted, and commonly used syntax to promote understanding and use of these approaches. Throughout, we provide a sample research question to facilitate discussion of the advantages and disadvantages of each technique.

Time is Money: Relative Value Units and Operative Time in Otolaryngology.

OBJECTIVES: Physician compensation for procedures is typically rooted in the work relative value unit (wRVU) system. Operative time is one of the factors that goes into the determination of wRVU assignment. There should be consistency between the wRVU/hr rate, irrespective of average operative time required to perform certain procedures. We investigate if wRVU assignment for otolaryngology procedures adequately accounts for increased operative time. STUDY DESIGN: Retrospective analysis of a surgical database. METHODS: NSQIP was queried from 2015-2018 for the top 50 most frequently performed otolaryngology Current Procedural Terminology (CPT) codes completed as standalone procedures. Median operative time was determined for each CPT code, and wRVU/hr was calculated. Correlations between operative time, wRVU, and wRVU/hr were investigated using linear regression analysis. A secondary analysis using complication rate as an indicator for procedure complexity was performed to examine the relation between wRVUs and complication rates. RESULTS: Fifty CPT codes containing 64,084 patients where only one code was reported were included in this analysis. The median operative time was 84 minutes, median wRVU was 11.23, and median wRVU/hour was 7.96. Linear regression analysis demonstrated a strong positive correlation between operative time and wRVU assignment (R2 = 0.805, P < .001). Further analysis found no correlation between operative time and wRVU/hr (R2 = 0.008, P = .525). Linear regression of wRVU/hr and complication rate showed a statistically significant positive correlation (R2 = 0.113, P = .017). CONCLUSION: This analysis suggests that compensation for otolaryngology procedures is positively correlated with operative time. Surgeries where more than one code is reported could not be evaluated, thus excluding some common combination of procedures performed by otolaryngologists.

Medicare Reimbursement Trends for Facility Performed Otolaryngology Procedures: 2000-2019.

OBJECTIVE: There is a paucity of data regarding financial trends for procedural reimbursements in otolaryngology. The purpose of this study was to evaluate monetary trends in Medicare reimbursement rates for the 20 most commonly billed otolaryngology procedures from 2000 to 2019. STUDY DESIGN: Analysis of physician reimbursement. METHODS: The American Academy of Otolaryngology-Head and Neck Surgery database was queried to determine the 20 most performed otolaryngology procedures. Next, the Physician Fee Schedule Look-Up Tool from the Centers for Medicare and Medicaid Services was utilized to assess each of the top 20 most utilized Current Procedural Terminology (CPT) codes in otolaryngology, and reimbursement data was extracted. All monetary data was adjusted for inflation to 2019 U.S. dollars using changes to consumer price index. Average annual and total percentage change in reimbursement were calculated based on adjusted values for all included procedures. RESULTS: After adjusting for inflation, the average reimbursement for the total 20 procedures decreased by 37.63% from 2000 to 2019. The greatest single mean decrease was seen in CPT code 61782 for stereotaxis procedures on the skull, meninges, and brain (-59.96%), whereas the smallest mean decrease was in CPT code 30520 for septoplasty (-1.50%). From 2000 to 2019, the adjusted reimbursement rate for the combined procedures decreased by an average of 2.33% each year. CONCLUSION: Medicare reimbursement for included procedures has decreased from 2000 to 2019. Increased awareness and consideration of these trends will be important for policy makers, hospitals, and surgeons in order to assure continued access to meaningful otolaryngology care in the United States.

Impact of a specialty trained billing team on an academic otolaryngology practice.

PURPOSE: To determine how the incorporation of specialty specific training for coders within a focused billing team affected revenue, efficiency, time to reimbursement, and physician satisfaction in an academic otolaryngology practice. MATERIALS AND METHODS: Our academic otolaryngology department recently implemented a new billing system, which incorporated additional training in otolaryngology surgical procedures for medical coders. A mixed model analysis of variance was used to compare billing outcomes for the 6 months before and 6 months after this new approach was initiated. The following metrics were analyzed: Current Procedural Terminology codes, total charges, time between services rendered and billing submission, and time to reimbursement. A survey of department physicians assessing satisfaction with the system was reviewed. RESULTS: There were 4087 Current Procedural Terminology codes included in the analysis. In comparing the periods before and after implementation of the new system, statistically significant decreases were found in the mean number of days to coding completion (19.3 to 12.0, respectively, p < 0.001), days to posting of charges (27.0 to 15.2, p < 0.001), days to final reimbursement (54.5 to 27.2, p < 0.001), and days to closure of form (179.2 to 76.6, p < 0.001). Physician satisfaction with communication and coder feedback increased from 36% to 64% after initiation of the new program. CONCLUSIONS: The implementation of additional specialty training for medical coders in the otolaryngology department of a large medical system was associated with improved revenue cycle efficiency. Additionally, this model appears to improve physician satisfaction and confidence with the coding system.

Cost Considerations for Robotic Surgery.

Transoral robotic surgery (TORS) is a rapidly growing diagnostic and therapeutic modality in otolaryngology-head and neck surgery, having already made a large impact in the short time since its inception. Cost-effectiveness analysis is complex, and a thorough cost-effectiveness inquiry should analyze not only financial consequences but also impact on the health state of the patient. The cost-effectiveness of TORS is still under scrutiny, but the early data suggest that TORS is a cost-effective method compared with other available options when used in appropriately selected patients.

Revaluation of Otolaryngologic Procedures With 10- and 90-Day Global Periods in the Medicare Physician Fee Schedule.

A recent investigation by the Centers for Medicare and Medicaid Services (CMS) suggests that physicians provide fewer postoperative visits (POVs) than expected for procedures with 10- and 90-day global periods. CMS is now contemplating revaluation of these procedures, which could result in lower Medicare payments to otolaryngologists. To estimate the impact of such reform on otolaryngologic procedures, we conducted a secondary subgroup analysis of CMS-contracted research, which used claims-based estimates of POVs to revalue procedures with 10- and 90-day global periods. Among the top 10 highest volume procedures performed in 2018, the proportion of median physician-reported to CMS-expected POVs ranged between 0.0% (myringotomy ± ventilation tube insertion, mouth biopsy, and complex wound repair) and 40.0% (total thyroidectomy). The top 5 procedures accounted for nearly three-quarters ($6.2 million and $8.6 million; 72.6%) of the estimated Medicare payment reduction. Further study is necessary to guide the development of equitable and effective payment reform.

Trends in Ambulatory Surgery Center Utilization for Otolaryngologic Procedures among Medicare Beneficiaries, 2010-2017.

OBJECTIVE: Surgical care is increasingly shifting to freestanding ambulatory surgical centers (ASCs). The extent to which otolaryngologists use ASCs has implications for patient safety and health care spending. This study characterizes trends in utilization and resultant financial implications for common otolaryngologic procedures performed at ASC and hospital outpatient departments (HOPDs). STUDY DESIGN: Retrospective cross-sectional analysis. SETTING: ASCs, HOPDs. SUBJECTS AND METHODS: Subjects included Medicare beneficiaries undergoing outpatient otolaryngologic procedures between 2010 and 2017. Procedures included the 20 highest-volume procedures performed by otolaryngologists at ASCs in 2017. Main outcomes included absolute and relative percentage difference in the proportion of procedures furnished at ASCs and HOPDs and estimated Medicare cost savings resulting from increased ASC utilization between 2011 and 2017. RESULTS: The proportion of outpatient otolaryngologic procedures performed at ASCs increased by 1.8% (relative difference: 10.0%; mean annual relative increase: 1.60%), and the proportion located at HOPDs decreased by 6.0% (relative difference: -11.8%; mean annual relative decrease: -1.6%) between 2010 and 2017. Rhinoplasty accounted for the largest absolute increase in ASC utilization over the study period (absolute [relative] 8.9% [33.5%]). Increased ASC utilization resulted in an estimated $7.1 million in cost savings to Medicare between 2011 and 2017. CONCLUSION: Otolaryngologists shifted outpatient surgical care from HOPDs to ASCs between 2010 and 2017, with resultant reductions in Medicare expenditures. Further research is necessary to examine the impact of this shift on patient safety.

Outcomes Assessment of Multi-Level Sleep Surgery in Syndromic Versus Non-Syndromic Children.

OBJECTIVES: Analyze the differences in length of stay, cost, disposition, and demographics between syndromic and non-syndromic children undergoing multi-level sleep surgery. METHODS: Children with sleep disordered breathing or obstructive sleep apnea that had undergone sleep surgeries were isolated from the 1997 to 2012 editions of the Kids' Inpatient Database, Healthcare Cost and Utilization Project, Agency for Healthcare Research and Quality. Children were then classified as syndromic or non-syndromic and stratified by level of sleep surgery (tonsillectomy & adenoidectomy, tonsillectomy & adenoidectomy plus other site surgery, other site surgery). Length of stay and cost were reported with Kruskal-Wallis one-way analysis of variance, disposition with binomial logistic regression, and demographics with chi-square. RESULTS: Syndromic children compared to non-syndromic children were more likely to have surgery beyond just tonsillectomy & adenoidectomy and also had a longer length of stay, higher total cost and non-routine disposition (all P < .001). Syndromic children undergoing tonsillectomy and adenoidectomy plus other site surgery had a longer length of stay compared to syndromic children undergoing tonsillectomy & adenoidectomy (6.00 days vs 3.63 days, P < .001). However, no similar statistically significant difference in length of stay was found in non-syndromic children (2.01 days vs 2.87 days, P > .05). CONCLUSION: The potential risks/benefits need to be weighed carefully before undertaking sleep surgery in syndromic children. They experience a longer length of stay, higher cost, and non-routine disposition when compared to non-syndromic children. This is especially true when considering the transition from tonsillectomy & adenoidectomy to tonsillectomy & adenoidectomy plus other site surgery, as syndromic children experience a longer length of stay and non-syndromic children do not.

Hospital utilization for orbital and intracranial complications of pediatric acute rhinosinusitis.

BACKGROUND: Orbital and intracranial complications of pediatric acute rhinosinusitis (ARS) are uncommon. With a risk of significant morbidity, hospital utilization and the financial burden of these entities are often high. We sought to assess utilization trends for complicated ARS and elucidate which factors influence cost. METHODOLOGY: Analysis of Kids' Inpatient Database (2006, 2009 and 2012). Children were selected based on diagnosis codes for ARS and grouped as: uncomplicated ARS, orbital complications (OC), or intracranial complications (IC). Patients with IC were subdivided into abscess (ICa), meningitis, or sinus thrombosis. Length of stay (LOS), cost and management information were analysed. Data presented as median [IQR]. RESULTS: A weighted total of 20,775 children were included. OC and IC were observed in 10.9% and 2.7% of these patients. LOS was longer for IC compared to OC (9 [8] v 4 [3]days, p < 0.001). Daily cost for IC was greater than OC ($2861 [4044] v $1683 [1187], p < 0.001), likely due to differences in need for surgery (IC 66.3% v OC 37.1%, p < 0.001). Within the ICa group, patients who received both otolaryngologic (ENT) and neurosurgery, compared to neurosurgery alone, had higher total cost ($41,474 [41,976] v $32,299 [18,235], p < 0.001) but similar LOS (12 [10] v 11 [9] days, p = 0.783). CONCLUSIONS: Children with IC required more surgery than their OC counterparts, resulting in a longer LOS and increased cost. Within the ICa group, the addition of ENT surgery to neurosurgery resulted in higher costs, but with a similar LOS. Considering the increased costs, the additional benefit of ENT surgery to those with children with IC should be investigated further.

A contemporary analysis of racial disparities in recommended and received treatment for head and neck cancer.

BACKGROUND: Racial disparities in squamous cell carcinoma of the head and neck (HNSCC) negatively affect non-Hispanic black (NHB) patients. This study was aimed at understanding how treatment is prescribed and received across all HNSCC subsites. METHODS: With the National Cancer Database, patients from 2004 to 2014 with surgically resectable HNSCCs, including tumors of the oral cavity (OC), oropharynx (OP), hypopharynx (HP), and larynx (LX), were studied. The treatment received was either upfront surgery or nonsurgical treatment. Treatment patterns were compared according to race and subsite, and how these differences changed over time was evaluated. RESULTS: NHB patients were less likely than non-Hispanic white (NHW) patients to receive surgery across all subsites (relative risk [RR] for OC, 0.87; RR for OP, 0.75; RR for HP, 0.73; RR for LX, 0.87; all P values <.05). They were also more likely to refuse a recommended surgery (RR for OC, 1.50; RR for OP, 1.23; RR for HP, 1.23; RR for LX, 1.34), and this difference was significant except for HP. NHB patients were more likely to not be offered surgery across all subsites (RR for OC, 1.38; RR for OP, 1.07; RR for HP, 1.05; RR for LX, 1.03; all P values <.05). Rates of surgery increased and rates of not being offered surgery declined for both NHB and NHW patients from 2004 to 2014, but the absolute disparities persisted in 2014. CONCLUSIONS: Across all HNSCC subsites, NHB patients were less likely than NHW patients to be recommended for and receive surgery and were more likely to refuse surgery. These differences have closed over time but persist. Enhanced shared decision making may improve these disparities.

The use and cost-effectiveness of intraoperative navigation in pediatric sinus surgery.

OBJECTIVES/HYPOTHESIS: There are consensus statements about when to use intraoperative navigation (IN) in adult sinus surgery. However, no corresponding guidelines exist for pediatrics. Our objectives included: 1) assess the demographic and operative factors associated with IN use and 2) calculate the cost-effectiveness of IN use. STUDY DESIGN: Retrospective chart review. METHODS: One hundred nineteen pediatric patients undergoing sinus surgery between 2003 and 2016 were reviewed. Demographic and surgical factors were collected from medical records. Costs associated with use of IN were gathered from billing records. RESULTS: Of the 119 patients, 60 underwent sinus surgery with navigation (wIN) and 59 underwent surgery without navigation (sIN). Children in the wIN group had more complex surgeries with more sinuses opened (P = .008). Individual attending surgeon and presence of trainee were associated with increased use of IN (P < .001 for both). IN resulted in a median of 31.5 minutes longer surgical time (P < .001). IN had an incremental cost/effectiveness ratio (ICER) of $22,378 for each year without revision surgery for patients with acute disease. However, for patients with chronic disease, the probability of undergoing a second surgery was the same between wIN and sIN groups, and navigation was not cost-effective (ICER of -$3,583). CONCLUSIONS: IN use did not decrease complications or rates of revision surgery. It was used primarily as an educational tool or to increase confidence in intraoperative identification of landmarks. However, the use of IN added surgical time and was not cost-effective. Further research must be completed to determine when IN is indicated in pediatric sinus surgery.

Office-based vs. operating room-performed laryngopharyngeal surgery: a review of cost differences.

PURPOSE: Office-based transnasal flexible endoscopic surgery under topical anesthesia has recently been developed as an alternative for transoral laryngopharyngeal surgery under general anesthesia. The aim of this study was to evaluate differences in health care costs between the two surgical settings. METHODS: PubMed, EMBASE and Cochrane Library were searched for studies reporting on costs of laryngopharyngeal procedures that could either be performed in the office or operating room (i.e., laser surgery, biopsies, vocal fold injection, or hypopharyngeal or esophageal dilation). Quality assessment of the included references was performed. RESULTS: Of 2953 identified studies, 13 were included. Quality assessment revealed that methodology differed significantly among the included studies. All studies reported lower costs for procedures performed in the office compared to those performed in the operating room. The variation within reported hospital and physician charges was substantial. CONCLUSION: Office-based laryngopharyngeal procedures under topical anesthesia result in lower costs compared to similar procedures performed under general anesthesia.

Assessment of cost of illness and quality of life in chronic rhinosinusitis patients with surgical treatment.

OBJECTIVE: Chronic rhinosinusitis (CRS) is a popular and tiring disease with significant impacts on the economy and on the Health-related Quality of Life (HRQOL) of patients. This study aims to estimate the cost of illness (COI) and to assess the Health-related Quality of Life (HRQOL) in patients with CRS who underwent surgery in Vietnam and to analyse the relationship between socio-demographic characteristics and the COI as well as the HRQOL. METHODS: A cross-sectional study was conducted in Ear, Nose, Throat Hospital in Ho Chi Minh City (ENT Hospital HCMC), Vietnam between August and October 2018. The direct medical and non-medical costs, the indirect costs (productivity loss), and the HRQOL of patients with CRS were measured. A subjective assessment of quality of life (QOL) using EuroQol 5 Dimensions 5 Levels (EQ-5D-5L) was used to evaluate the health status of these patients after surgery. Characteristics related with the COI and the HRQOL were identified by multiple regression. RESULTS: A total of 264 inpatients with CRS participated in the study. The mean COI for inpatients with CRS was $812.83 and direct costs accounted for a major proportion (89.32%) of the total cost. In addition, the surgery represented the most significant direct medical cost with 58.57% of the total cost. Most of the patients reported no problems with mobility (89.1%), self-care (93.9%), usual activities (77.2%), and anxiety/depression (64.0%). The mean EQ-5D-5L utility score was 0.76 (SD = 0.17), and the mean Visual Analogue Scale (EQ-VAS) score was 76.57 (SD = 13.34). The results of multiple regression showed that gender, occupations, monthly income, prior surgery and family history of CRS affected the total cost while the HRQOL of patients were related to education, smoking behaviour, exercise behaviour and family history of CRS. CONCLUSIONS: This study showed that although endoscopic sinus surgery (ESS) accounted for the largest expense in the COI, this surgical treatment helped to improve the HRQOL in patients with CRS. The findings provided a reference for policy makers in CRS management as well as for adjustment of costs for patients so as to reduce disease burden and to enhance their QOL.

Does Surgical Volume and Complexity Affect Cost and Mortality in Otolaryngology-Head and Neck Surgery?

OBJECTIVES: (1) To evaluate whether admission volume and case complexity are associated with mortality rates and (2) evaluate whether admission volume and case complexity are associated with cost per admission. STUDY DESIGN: Retrospective case series. SETTING: Tertiary academic hospital. SUBJECTS AND METHODS: The Vizient database was queried for inpatient admissions between July 2015 and March 2017 to an otolaryngology-head and neck surgery service. Data collected included admission volume, length of stay, intensive care unit (ICU) status, complication rates, case mix index (CMI), and cost data. Regression analysis was performed to evaluate the relationship between cost, CMI, admission volume, and mortality rate. RESULTS: In total, 338 hospitals provided data for analysis. Mean hospital admission volume was 182 (range, 1-1284), and mean CMI was 1.69 (range, 0.66-6.0). A 1-point increase in hospital average CMI was associated with a 40% increase in odds for high mortality. Admission volume was associated with lower mortality, with 1% lower odds for each additional case. A 1-point increase in CMI produces a $4624 higher total cost per case (95% confidence interval, $4550-$4700), and for each additional case, total cost per case increased by $6. CONCLUSION: For otolaryngology inpatient services at US academic medical centers, increasing admission volume is associated with decreased mortality rates, even after controlling for CMI and complication rates. Increasing CMI levels have an anticipated correlation with higher total costs per case, but admission volume is unexpectedly associated with a significant increase in average cost per case.
