RESUMEN
Sensorineural hearing loss results from abnormalities that affect the hair cells of the membranous labyrinth, inner ear malformations, and conditions affecting the auditory pathway from the cochlear nerve to the processing centers of the brain. Cochlear implantation is increasingly being performed for hearing rehabilitation owing to expanding indications and a growing number of children and adults with sensorineural hearing loss. An adequate understanding of the temporal bone anatomy and diseases that affect the inner ear is paramount for alerting the operating surgeon about variants and imaging findings that can influence the surgical technique, affect the choice of cochlear implant and electrode type, and help avoid inadvertent complications. In this article, imaging protocols for sensorineural hearing loss and the normal inner ear anatomy are reviewed, with a brief description of cochlear implant devices and surgical techniques. In addition, congenital inner ear malformations and acquired causes of sensorineural hearing loss are discussed, with a focus on imaging findings that may affect surgical planning and outcomes. The anatomic factors and variations that are associated with surgical challenges and may predispose patients to periprocedural complications also are highlighted. © RSNA, 2023 Quiz questions for this article are available through the Online Learning Center. Online supplemental material and the slide presentation from the RSNA Annual Meeting are available for this article.

CONTEXT: Pituitary tumors are the third most common brain tumor and yet there is no standardization of the surveillance schedule and assessment modalities after transsphenoidal surgery. EVIDENCE ACQUISITION: OVID, EMBASE and the Cochrane Library databases were systematically screened from database inception to March 5, 2020. Inclusion and exclusion criteria were designed to capture studies examining detection of pituitary adenoma recurrence in patients 18 years of age and older following surgical resection with curative intent. EVIDENCE SYNTHESIS: A total of 7936 abstracts were screened, with 812 articles reviewed in full text and 77 meeting inclusion criteria for data extraction. A pooled analysis demonstrated recurrence rates at 1 year, 5 years and 10 years for non-functioning pituitary adenomas (NFPA; N = 3533 participants) were 1%, 17%, and 33%, for prolactin-secreting adenomas (PSPA; N = 1295) were 6%, 21%, and 28%, and for growth-hormone pituitary adenomas (GHPA; N = 1257) were 3%, 8% and 13%, respectively. Rates of recurrence prior to 1 year were 0% for NFPA, 1-2% for PSPA and 0% for GHPA. The mean time to disease recurrence for NFPA, PSPA and GHPA were 4.25, 2.52 and 4.18 years, respectively. CONCLUSIONS: This comprehensive review of the literature quantified the recurrence rates for commonly observed pituitary adenomas after transsphenoidal surgical resection with curative intent. Our findings suggest that surveillance within 1 year may be of low yield. Further clinical trials and cohort studies investigating cost-effectiveness of surveillance schedules and impact on quality of life of patients under surveillance will provide further insight to optimize follow-up.

BACKGROUND: Positive deviance (PD) seminars, which have shown excellent results in improving the quality of surgical practices, use individual performance feedback to identify team members who outperform their peers; the strategies from those with exemplary performance are used to improve team members' practices. Our study aimed to use the PD approach with arthroplasty surgeons and nurses to identify multidisciplinary strategies and recommendations to improve operating room (OR) efficiency. METHODS: We recruited 5 surgeons who performed high-volume primary arthroplasty and had participated in 4-joint rooms since 2012, and 29 nurses who had participated in 4-joint rooms and in at least 16 cases in our data set. Three 1-hour PD sessions were held in February and March 2021: 1 with surgeons, 1 with nurses, and 1 with both surgeons and nurses to select recommendations for implementation. The sessions were led by a member of the nonorthopedic surgical faculty who was familiar with the subjects discussed and with PD seminars. To determine the success of the recommendations, we compared OR efficiency before and after implementation. We defined success as performance of 4 joint procedures within 8 hours. RESULTS: Eleven recommendations were recorded from the session with nurses and 7 from the session with surgeons, of which 11 were selected for implementation. During the month after implementation, there were great improvements across all time intervals of surgical procedures, with the greatest improvements seen in mean anesthesia preparation time in the room (4.51 min [26.3%]), mean procedure duration (9.75 min [14.0%]) and mean anesthesia finish time (5.78 min [44.0%]) (all p < 0.001). The total time saved per day was 49.84 minutes; this led to a success rate of 69.0%, a relative increase of 73.8% from our 2012-2020 success rate of 39.7% (p < 0.001). CONCLUSION: The recommendations and increased motivation owing to the individualized feedback reduced time spent per case, allowing more days to finish on time. Positive deviance seminars offer an inexpensive, efficient and collegial means for process improvement in the OR.

PURPOSE: The objective of this study was to compare the cost-effectiveness of preoperative octreotide therapy followed by surgery versus the standard treatment modality for growth-hormone secreting pituitary adenomas, direct surgery (that is, surgery without preoperative treatment) from a public third-party payer perspective. METHODS: We developed an individual-level state-transition microsimulation model to simulate costs and outcomes associated with preoperative octreotide therapy followed by surgery and direct surgery for patients with growth-hormone secreting pituitary adenomas. Transition probabilities, utilities, and costs were estimated from recent published data and discounted by 3% annually over a lifetime time horizon. Model outcomes included lifetime costs [2020 United States (US) Dollars], quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios (ICERs). RESULTS: Under base case assumptions, direct surgery was found to be the dominant strategy as it yielded lower costs and greater health effects (QALYs) compared to preoperative octreotide strategy in the second-order Monte Carlo microsimulation. The ICER was most sensitive to probability of remission following primary therapy and duration of preoperative octreotide therapy. Accounting for joint parameter uncertainty, direct surgery had a higher probability of demonstrating a cost-effective profile compared to preoperative octreotide treatment at 77% compared to 23%, respectively. CONCLUSIONS: Using standard benchmarks for cost-effectiveness in the US ($100,000/QALY), preoperative octreotide therapy followed by surgery may not be cost-effective compared to direct surgery for patients with growth-hormone secreting pituitary adenomas but the result is highly sensitive to initial treatment failure and duration of preoperative treatment.

BACKGROUND: Opioid-related morbidity and mortality continue to rise in the province of Ontario. We implemented a provincial campaign to reduce the number of opioid pills prescribed at discharge after surgery in the Ontario Surgical Quality Improvement Network (ON-SQIN). METHODS: Activities related to the provincial campaign were implemented between April 2019 and March 2020 and between October 2020 and March 2021. Self-reported data from participating hospitals were used to determine changes in postoperative opioid prescribing patterns across participating hospitals. RESULTS: A total of 33 and 26 hospitals participated in the provincial campaign in the first and second year, respectively. During the first year of the campaign, the median morphine equivalent (MEQ) from opioid prescriptions decreased significantly in a number of surgical specialties, including General Surgery (from 105 [75-130] to 75 [55-107], P < 0.001) (median, interquartile range) and Orthopedic Surgery (from 450 [239-600] to 334 [167-435], P < 0.001). The median number of opioid pills prescribed at discharge per surgery also decreased significantly, from 25 (15-53) to 15 (11-38) for 1 mg hydromorphone (P < 0.001) and 25 (20-51) to 20 (15-30) for oxycodone (P < 0.001). The decrease in opioid prescriptions continued in the second year of the campaign. CONCLUSIONS: Our approach resulted in a significant reduction in the number of postoperative opioids prescribed across a number of surgical specialties. Our findings indicate that evidence-based strategies derived from a regional collaborative network can be leveraged to promote and sustain quality improvement activities.

OBJECTIVE: Post-implant rehabilitation is limited for adult cochlear implant (CI) recipients. The objective of this research was to capture the perspectives of CI users and their coaches regarding their experiences with auditory-verbal intervention as an example of post-implant rehabilitation and their views on perceived benefits and challenges related to the intervention. DESIGN: This qualitative study involved semi-structured focus group interviews with adult CI users and their coaches who accompanied them in a 24-week auditory-verbal intervention program. STUDY SAMPLE: A total of 17 participants (eight CI users and nine coaches) contributed to the interviews. RESULTS: Three key topic areas emerged from the interviews capturing CI users' and coaches' experiences related to the intervention program: (1) benefits of the intervention, (2) factors affecting experiences, and (3) challenges and barriers. Benefits included increased confidence in hearing, communication, social participation, and new knowledge about technology and hearing. Factors affecting the experience were participants' motivation and the therapist's skills. The primary challenge was the time commitment for weekly therapy. CONCLUSIONS: Both CI users and coaches perceived a focussed auditory-verbal intervention to be beneficial in improving speech understanding, confidence in using hearing, social interaction, and knowledge about technology. Participants recommended reducing the intensity of intervention to facilitate participation.

OBJECTIVES: To examine the association between surgical site infections (SSIs) and hospital readmissions and all-cause mortality, and to estimate the attributable health care costs of SSIs 1 year following surgery. BACKGROUND: SSIs are a common postoperative complication; the long-term impact of SSI on health outcomes and costs has not been formally evaluated. METHODS: This retrospective cohort study included all adult patients who underwent surgery at the 1202-bed teaching hospital in Ottawa, Ontario, Canada, and were included in the National Surgical Quality Improvement Program database between 2010 and 2015. The study exposure was postoperative SSI. The study outcomes included hospital readmission, all-cause mortality, and health care costs at 1 year (primary) and at 30 days and 90 days (secondary) following surgery. RESULTS: We identified 14,351 patients, including 795 patients with SSIs. Our multivariable analyses that accounted for competing risks demonstrated that at 1-year following the index date, superficial and deep/organ space SSIs were significantly associated with an increase in hospital readmission [hazard ratio (HR) = 1.63, 95% confidence interval (95% CI) 1.39-1.92 and HR = 3.49, (95% CI 2.76-4.17, respectively) and all-cause mortality (HRâ= 1.35, 95% CI 1.10-1.98 and HR = 2.21, 95% CI 1.44-2.78, respectively]. At 1 year after surgery, patients with superficial and deep/organ space SSIs incurred higher health care costs C$20,648 (95% CI) C$16,980- C$24,112and C$53,075 (95% CI) C$44,628- C$60,936), than non-SSI patients. CONCLUSION: SSIs, especially deep/organ space SSI, contribute to adverse health outcomes and health care costs across the entire year after surgery. Our findings highlight the importance of effective prevention/monitoring strategies targeting both short- and long-term consequences of SSI.

OBJECTIVE: To quantify the effect of blood transfusion on the risk of venous thromboembolism (VTE) among women undergoing hysterectomy for non-malignant indications. METHODS: A retrospective cohort study using the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) was conducted. Women who underwent hysterectomy for non-malignant indications between 2011 and 2016 were identified using the Current Procedural Terminology and Internationally Classification of Diseases codes. The primary outcome was development of VTE. Data on patient demographics and perioperative variables were obtained. Pair-wise comparison using χ2 tests were performed to compare women with and without VTE. Multivariable logistic regression was performed to adjust for potential confounders and identify independent predictors of VTE. RESULTS: Between 2011 and 2016, 169 593 women underwent hysterectomy for non-malignant indications. The overall incidence of VTE was 0.32%. Patient characteristics associated with VTE included obesity and higher American Society of Anesthesiologists (ASA) status. Associated operative factors included abdominal surgery, blood transfusion, and prolonged operative time (P < 0.05 for all). Following adjustment for potential confounders, abdominal hysterectomy was associated with greater odds of VTE than laparoscopic or vaginal approaches (adjusted odds ratio [aOR] 1.81; 95% CI 1.48-2.21 and aOR 2.31; 95% CI 1.62-3.28, respectively). Greater odds of VTE were also observed with OR time >150 minutes (aOR 1.88; 95% CI 1.46-2.42), ASA class ≥III (aOR 1.53; 95% CI 1.05-2.26), and intra- and postoperative transfusion (aOR 2.65; 95% CI 1.78-3.95 and aOR 2.98; 95% CI 1.95-4.55, respectively). CONCLUSION: The risk of VTE is low in women undergoing hysterectomy for non-malignant indications. Blood transfusion was associated with the highest risk of VTE.

BACKGROUND: There is no standard procedure regarding surgical treatment of multiligament knee injuries involving rupture of the posterior cruciate ligament. OBJECTIVE: Does the modified and purely arthroscopic operation technique show similarly good results compared to the familiar open tibial inlay technique? METHODS: A total of four patients were surgically treated using the open tibial inlay technique (group A) and seven using the modified arthroscopic approach (group B). The prospectively designed follow-up examination comprised the Lysholm score, the subjective questionnaire of the International Knee Documentation Committee (IKDC) score as well as the specifically extended Orthopedic Working Group Knee (OAK) score for clinical assessment. Tests on translational movability of the knee joint were performed with the Rolimeter®. The level of statistical significance alpha was set at 5%. RESULTS: The follow-up examination took place on average 28.5⯱ 19.60 months and 30.6⯱ 26.26 months postoperatively in groups A and B, respectively. Groups A and B recorded mean 70.3⯱ 5.32 and 69.6⯱ 19.82 points in the Lysholm score, respectively. In the subjective IKDC score group A showed 67.3⯱ 7.76 points and group B 65.9⯱ 12.35 points. The OAK score was 77.5⯱ 6.10 points in group A and 75.3⯱ 11.31 points in group B. The side difference in the posterior drawer test was 1.75⯱ 1.192â¯mm in group A and 2.50⯱ 2.160â¯mm in group B. In the reverse Lachman test differences of 2.37⯱ 2.175â¯mm and 3.22⯱ 2.059â¯mm were measured in groups A and B, respectively. All values showed no significant differences between the two evaluated groups. CONCLUSION: The results of the two operation techniques were not significantly different. The arthroscopic approach is therefore regarded as the preferred method in this institute.

STUDY OBJECTIVE: To quantify the relationship between type of benign pelvic disease and risk of surgical site infection (SSI) after hysterectomy. DESIGN: Retrospective cohort study (Canadian Task Force classification II-2). SETTING: Hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program (NSQIP). PATIENTS: Women who underwent hysterectomy from 2006-2015 and recorded in NSQIP database. INTERVENTION: None. MEASUREMENTS AND MAIN RESULTS: SSI risk was compared for type of benign pelvic disease, patient characteristics (i.e., age, race, and selected comorbidities) and process of care variables (i.e., admission status, type of hysterectomy, and operative time). SSI occurred in 2.48% of the 125,337 women who underwent hysterectomy. SSI was most frequent in patients with endometriosis and least frequent in those with genital prolapse (3.13% vs 1.39%; p <.0001). Following adjustment for potential confounders, the odds of SSI were higher in women undergoing hysterectomy for endometriosis (adjusted odds ratio [aOR], 1.79; 95% confidence interval [CI], 1.43- 2.25), uterine myomas (aOR, 1.28; 95% CI, 1.05-1.55), menstrual disorders (aOR, 1.46; 95% CI, 1.20-1.78), and pelvic pain (aOR, 1.75; 95% CI, 1.34-2.27) compared with women undergoing hysterectomy for genital prolapse. Other patient factors associated with SSI included age, body mass index, smoking, diabetes mellitus, chronic obstructive pulmonary disease, hypertension, and American Society of Anesthesiologists classification. Among process-of-care factors, inpatient status, route of hysterectomy, total vs subtotal hysterectomy, and operative time were also associated with SSI. CONCLUSION: In addition to various patient and process-of-care factors known to be associated with SSI, type of underlying pelvic disease is an independent risk factor for SSI in women undergoing hysterectomy for benign indications.

STUDY OBJECTIVE: Because of the rapid decline in vaginal hysterectomy (VH) cases in recent years, there is concern regarding gynecologic surgical training and proficiency for VH. The objective of this study is to determine the effect of surgical trainee involvement on surgical outcomes in VH cases performed for benign indications. DESIGN: Retrospective, multicenter, cohort study (Canadian Task Force classification II-2). SETTING: Participating hospitals in the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) at various international sites. PATIENTS: Women who underwent VH for benign indication enrolled from the ACS-NSQIP from 2006 to 2012. INTERVENTION: ACS-NSQIP database. MEASUREMENTS AND MAIN RESULTS: Our study included 5756 patients who underwent VH, and surgical trainees were present in 2276 cases (39.5%). Patients who had a trainee present during VH were more likely to be older, nonsmoking, have comorbidities, and be classified as American Society of Anesthesiologists class III or IV. They were also more likely to be admitted as inpatients, undergo concomitant adnexal surgery, and have uterine weight greater than 250 g. Trainee presence during VH was associated with increased rates of overall complications (5.1% vs 3.19%, p < .001), urinary tract infection (5.27% vs 2.64%, p < .001), and operative time (124.25 ± 59.29 minutes vs 88.64 ± 50.9 minutes, p < .001). After controlling for baseline characteristics, trainee presence was associated with increased odds of overall complications (adjusted odds ratio, 1.63; 95% confidence interval, 1.25-2.13), urinary tract infection (adjusted odds ratio, 2.02; 95% confidence interval, 1.51-2.69), and prolonged operative time (adjusted odds ratio, 3.65; 95% confidence interval, 3.20-4.15). No differences were observed for other measures of surgical morbidity or mortality. CONCLUSION: Despite the increased patient complexity and operative time associated with teaching cases, the involvement of surgical trainees is associated with urinary tract infection but not with any major surgical morbidity or mortality. These findings have important implications for gynecologic surgical training for VH.

This study reports on a nationally representative sample of married individuals ages 25-50 (N = 3,000) surveyed twice (1 year apart) to investigate the phenomenon of divorce ideation, or what people are thinking when they are thinking about divorce. Twenty-eight percent of respondents had thought their marriage was in serious trouble in the past but not recently. Another 25% had thoughts about divorce in the last 6 months. Latent Class Analysis revealed three distinct groups among those thinking about divorce at Time 1: soft thinkers (49%), long-term-serious thinkers (45%), and conflicted thinkers (6%). Yet, divorce ideation was not static; 31% of Time 1 thinkers were not thinking about it 1 year later (and 36% of nonthinkers at Time 1 were thinking about it 1 year later). Also, Latent Transition Analysis revealed 49% of Time 1 long-term-serious thinkers, 56% of soft thinkers, and 51% of conflicted thinkers had shifted groups at Time 2, mostly in the direction of less and softer thinking about divorce. Overall, divorce ideation is common but dynamic, and it is not necessarily an indication of imminent marital dissolution.

SUMMARY: Many surgical departments are interested in quality improvement (QI). For sustainable success, front-line involvement is crucial for improving culture. Without improved culture, any QI strategy will be a struggle. Designing an infrastructure to support these principles is important. We describe our process creating this infrastructure, the multidisciplinary teams that drive change in our department and some of the processes and outcomes we have been able to improve.

OBJECTIVE: Candidacy criteria for cochlear implants have expanded to include children with complex developmental disabilities. The aim of this study was to determine the long-term benefits of cochlear implantation for this clinical population. DESIGN: The study involved a retrospective chart review. STUDY SAMPLE: The review identified 21 children with complex disabilities who had received cochlear implants in a pediatric center prior to 2004. Length of cochlear implant use was between 7.3 and 19.0 years. Long-term functional auditory abilities were assessed pre and post-operatively using measures appropriate to the child's level of functioning. Cognitive assessments and developmental data were also available for the children. RESULTS: Children's long-term speech recognition outcomes depended highly on their developmental status. Children with severe developmental delay showed no open-set speech recognition abilities while children with mild to moderate delays achieved open-set scores ranging from 48 to 94% on open-set word testing. Five of 13 (38%) children with complex needs had discontinued use of their cochlear implant. CONCLUSIONS: Long-term speech recognition abilities following cochlear implantation for children with complex developmental issues seem to be highly related to their developmental profile. Developmental status is an important consideration in counselling families as part of the cochlear implant decision process.

PURPOSE: Magnetic resonance imaging (MRI), electric compound action potential (eCAP), and electric auditory brainstem response (eABR) are among the routine assessments performed before and/or after cochlear implantation. The objective of this review was to systematically summarize and critically appraise existing evidence of the prognostic value of eCAP, eABR, and MRI for predicting post-cochlear implant (CI) speech perception outcomes in children, with a particular focus on the lesion site. METHOD: The present systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 statement. Three electronic databases (ProQuest, PubMed, and Scopus) were searched with no restrictions on language, publication status, or year of publication. Studies on children identified with sensorineural hearing loss, auditory neuropathy spectrum disorder, cochlear nerve deficiency, or cochleovestibular nerve abnormalities reporting the relevance of eCAP, eABR, and/or MRI results to CI speech perception outcomes were included. The literature search yielded 1,887 publications. Methodological quality and strength of evidence were assessed by the Crowe Critical Appraisal Tool and the Grading of Recommendations Assessment, Development, and Evaluation tool, respectively. RESULTS: Of the 25 included studies, the relevance of eCAP, eABR, and/or MRI findings to post-CI speech perception outcomes was reported in 10, 11, and 11 studies, respectively. The studies were strongly in support of the prognostic value of eABR and MRI for CI outcomes. However, the relevance of eCAP findings to speech perception outcomes was uncertain. CONCLUSION: Despite the promising findings, caution is warranted in interpreting them due to the observational and retrospective design of the included studies, as well as the heterogeneity of the population and the limited control of confounding factors within these studies.

RESUMEN
OBJECTIVES: Current evidence supports the benefits of cochlear implants (CIs) in children with hearing loss, including those with auditory neuropathy spectrum disorder (ANSD). However, there is limited evidence regarding factors that hold predictive value for intervention outcomes. DESIGN: This retrospective case-control study consisted of 66 children with CIs, including 22 with ANSD and 44 with sensorineural hearing loss (SNHL) matched on sex, age, age at CI activation, and the length of follow-up with CIs (1:2 ratio). The case and control groups were compared in the results of five open-set speech perception tests, and a Forward Linear Regression Model was used to identify factors that can predict the post-CI outcomes. RESULTS: There was no significant difference in average scores between the two groups across five outcome measures, ranging from 88.40% to 95.65%. The correlation matrix revealed that younger ages at hearing aid fitting and CI activation positively influenced improvements in speech perception test scores. Furthermore, among the variables incorporated in the regression model, the duration of follow-up with CIs, age at CI activation, and the utilization of two CIs demonstrated prognostic significance for improved post-CI speech perception outcomes. CONCLUSIONS: Children with ANSD can achieve similar open-set speech perception outcomes as children with SNHL. A longer CI follow-up, a lower age at CI activation, and the use of two CIs are predictive for optimal CI outcome.

PURPOSE: The objective of this overview of systematic reviews (SRs; umbrella review) was to systematically summarize and critically appraise current evidence of cochlear implant (CI) outcomes in children with auditory neuropathy spectrum disorder (ANSD). METHOD: This study was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 statement. The methodological quality and the risk of bias in the included SRs were assessed using A MeaSurement Tool to Assess systematic Reviews 2 checklist and the Risk of Bias in Systematic Reviews tool, respectively. RESULTS: According to eight included SRs, children with ANSD achieve CI outcomes (speech perception performance) similar to their peers with sensorineural hearing loss. In children with postsynaptic ANSD (cochlear nerve deficiency), cochlear nerve hypoplasia is associated with better speech recognition outcomes compared with cochlear nerve aplasia, especially in the absence of additional disabilities. Except for one study, the overall quality of the included SRs was critically low, and except for three studies, evidence of a high risk of bias was identified in other included SRs. CONCLUSIONS: Current evidence supports CI benefits for children with ANSD. To improve the quality of evidence, well-designed, prospective studies with appropriate sample sizes, using valid outcome measures, clarifying matching criteria, and taking into account the role of confounding factors are essential.
RESUMEN
Pulsatile tinnitus is a symptom with a potentially significant impact on the quality of life of patients.1 In some cases the pulsatile tinnitus is secondary to an arterial, arteriovenous, or a venous condition that can be treated endovascularly.2-5 One of the newly recognized entities that can cause pulsatile tinnitus is the presence of an ipsilateral aneurysmal diverticulum of the transverse sinus. The Woven EndoBridge (WEB) is an intra-aneurysmal flow disruptor for the treatment of broad-based arterial aneurysms with a high safety and effectiveness profile.3 The initial version of the WEB with a dual-layer structure evolved into a single-layer structure in two different versions (WEB SL, a barrel shape, and WEB SLS, a spherical shape).4 The WEB system does not require concomitant antiplatelet therapy, unlike other intraluminal devices such as flow diverters or intracranial stents. We describe a case of pulsatile tinnitus secondary to an aneurysmal diverticulum of the transverse sinus successfully treated with a WEB SL device instead of stent-assisted coiling, therefore alleviating the need for antiplatelets (video 1). The patient had an immediate clinical response with complete and persisting disappearance of her pulsatile tinnitus.neurintsurg;jnis-2023-020981v1/V1F1V1Video 1.
RESUMEN
OBJECTIVE: The aim of this study was to determine an optimal follow-up imaging surveillance strategy in terms of cost-effectiveness after resection of nonfunctioning pituitary adenomas with curative intent. METHODS: An individual-level state-transition microsimulation model was used to simulate costs and outcomes associated with three postoperative imaging strategies over a lifetime time horizon: 1) annual MRI surveillance, 2) tapered MRI surveillance (annual surveillance for 5 years followed by surveillance every 2 years), and 3) personalized surveillance (annual surveillance for 5 years followed by surveillance every 2 years when MRI shows remnant disease/postoperative changes, and surveillance at 7, 10, and 15 years for disease-free MRI). Transition probabilities, utilities, and costs were estimated from recent published data and discounted by 3% annually. Model outcomes included lifetime costs (2022 US dollars), quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios (ICERs). RESULTS: Under base case assumptions, annual surveillance yielded higher costs and lower health effects (QALYs) compared with the tapered and personalized surveillance strategies (dominated). Personalized surveillance demonstrated an additional 0.1 QALY at additional cost ($1298) compared with tapered surveillance (7.7 QALYs at a cost of $12,862). The ICER was $11,793/QALY. The optimal decision was most sensitive to the probability of postoperative changes on MRI after surgery and MRI cost. Accounting for parameter uncertainty, personalized surveillance had a higher probability of being a cost-effective surveillance option compared with the alternative strategies at 79%. CONCLUSIONS: Using standard cost-effectiveness thresholds in the US ($100,000/QALY), personalized surveillance that accounted for remnant disease or postoperative changes on MRI was cost-effective compared with alternative surveillance strategies.
