ImportanceIdentification of factors associated with variation in outpatient surgery may further quality improvement efforts to safely reduce postoperative hospital length of stay nationally.ObjectivesTo explore variation in the use of outpatient surgery, incorporating patient, geographic, and hospital factors.Design, Setting, and ParticipantsThis retrospective cross-sectional study used deidentified administrative claims data from OptumLabs Data Warehouse. Participants included adults who underwent 1 of 10 general, urological, or gynecological operations between January 1, 2015, and June 30, 2021, in the US. Patients who underwent combined procedures or reoperations or had at least 15 Elixhauser comorbidities were excluded. Data were analyzed from July 26 to December 16, 2023.ExposureInpatient or outpatient surgical procedures.Main Outcomes and MeasuresMultilevel logistic regression assessed variation in the use of outpatient surgery rates by hospital characteristics (bed size, presence of trainees, and rural referral center status) and hospital census division, adjusting for patient factors (age, sex, number of Elixhauser comorbidities, year, and rural-urban commuting area). This multilevel model allowed for the sources of variability to be quantitatively attributed to patient characteristics, geography, and hospital characteristics.ResultsA total of 330 424 (72.3%) of 456 954 included patients underwent outpatient surgery. The median age was 54 (IQR, 41-67) years, and of those with data available, most patients were female (268 692 of 414 193 [64.9%]). The likelihood of outpatient surgery varied significantly by hospital census division for all 10 operations (eg, MIS salpingo-oophorectomy range, 29.6%-58.8%; P < .001). Variation in hospital census division contributed most to outpatient surgery for 8 of 10 operations compared with other patient and hospital characteristics. Hospital census division contributed the greatest degree to the variation in outpatient simple mastectomy (20.6%) and the least to outpatient open ventral hernia repair (0.7%). Multivariable analysis showed that the odds of outpatient surgery for patients from metropolitan areas were higher for minimally invasive salpingo-oophorectomy (odds ratio [OR], 1.62; 95% CI, 1.34-1.95) and open ventral hernia repair (OR, 1.16; 95% CI, 1.09-1.24). Hospitals with 400 or more beds were independently associated with decreased odds of outpatient surgery compared with hospitals with 50 to 199 beds for 4 of 7 operations (MIS paraesophageal hernia repair [OR, 0.58; 95% CI, 0.47-0.71; P < .001]; MIS cholecystectomy [OR, 0.73; 95% CI, 0.68-0.78; P < .001]; open ventral hernia [OR, 0.51; 95% CI, 0.46-0.57; P < .001]; MIS ventral hernia repair [OR, 0.66; 95% CI, 0.56-0.77; P < .001]). The presence of a residency training program was independently associated with increased odds of outpatient surgery for simple mastectomy (OR, 1.35; 95% CI, 1.16-1.58; P < .001) and mastectomy with reconstruction (OR, 1.50; 95% CI, 1.27-1.77; P < .001) and decreased odds of outpatient surgery for minimally invasive cholecystectomy (OR, 0.96; 95% CI, 0.92-1.00; P = .04), open ventral hernia repair (OR, 0.93; 95% CI, 0.86-1.00; P = .04), and total thyroidectomy (OR, 0.84; 95% CI, 0.71-1.00; P = .04).Conclusions and RelevanceIn this cross-sectional study, significant variation existed in the use of outpatient surgery in the US and appeared to be driven primarily by hospital geography. Addressing these variations may improve the use of resources.

Objective We sought to characterize the frequency of postoperative opioid prescriptions in patients undergoing cleft lip repair (CLR). Design The NSQIP-P 2023 database was queried to identify patients undergoing CLR using CPT codes. Univariable analysis was conducted to identify factors associated with postoperative opioid prescription. Setting A multicenter sample from 157 participating sites. Patients/participants A total of 1497 cases (1215 unilateral CLR and 282 bilateral CLR) were identified. Main outcomes/measures The postoperative outcomes of interest were whether an opioid was prescribed to a patient at discharge and what factors were independently associated with opioid prescribing at discharge. Results A total of 44.6% of patients with a mean age of 5.1 ± 1.9 months were prescribed opioids at discharge, most commonly oxycodone (76.3%). Univariable analysis identified an increase in weight (kg) (OR: 1.09, 95% CI: 1.02-1.17, P = .03), American Society of Anesthesiologists (ASA) classification (ordinal) (OR: 1.25, 95% CI: 1.06-1.47, P = .01), anesthesia time (10 min) (OR: 1.02, 95% CI: 1.01-1.04, P = .03), and age (months) (OR: 1.06, 95% CI: 1.00-1.12, P = .04) as being associated with opioid prescription at discharge. Bilateral versus unilateral CLR ( P = .49) and outpatient versus inpatient operation ( P = .38) were not associated with opioid prescribing. Conclusion Opioid stewardship is important in pediatric care, with our results showing age, weight, anesthesia time, and ASA classifications are predictors of opioid prescription. Further research examining contributors to patient pain following CLR is necessary to optimize opioid prescribing without negatively impacting the patient.

Objective: To develop an artificial intelligence–based pipeline to assess and triage patient-submitted postoperative wound images. Background: The rise of outpatient surgeries, remote monitoring, and patient-submitted wound images via online portals has contributed to a growing administrative workload on clinicians. Early identification of surgical site infection (SSI) is essential for reducing postoperative morbidity. Methods: Patients ≥18 years old who underwent surgery at 9 affiliated Mayo Clinic hospitals (2019-2022) and were captured by the National Surgical Quality Improvement Program (NSQIP) were included. Eligibility required submission of one image via the patient portal within 30 days after surgery. Images were independently screened in duplicate to determine the presence of an incision. SSI outcomes were obtained from NSQIP. The developed model consisted of 2 stages: incision detection and SSI detection in images with incisions. Four pretrained architectures were evaluated using 10-fold cross-validation, with upsampling and data augmentation to mitigate class imbalance. An end-to-end pipeline, image quality assessment and sensitivity analysis stratified by race were also performed. Results: Among 6060 patients, the median age was 54 years (interquartile range: 40–65), 61.4% (n=3805) were female, and 92.5% (n=5731) identified as White. SSIs were confirmed in 6.2% (n=386) images. Vision Transformer outperformed all others, achieving an incision detection accuracy of 0.94 (area under the curve=0.98) and an SSI detection accuracy of 0.73 (area under the curve=0.81). In addition, it demonstrated strong performance in assessing image quality. Sensitivity analysis revealed comparable performance across racial subgroups. Conclusion: This artificial intelligence pipeline demonstrates promising performance in automating wound image assessment and SSI detection, reducing clinical workload and improving postoperative care.

Abstract Background Hospital‐at‐home programs (HaH) in the United States have evolved to include a virtual‐hybrid delivery model, where all physician encounters are virtual and partnered with a home care team. Objective To examine whether a virtual hybrid HaH program enabled by technology has similar clinical outcomes to traditional brick‐and‐mortar (B&M) hospital care. Methods We conducted a pragmatic trial at three hospitals, randomizing 1150 acutely ill patients requiring hospital care between July 10, 2023, and October 31, 2023 one‐to‐one into two groups: intervention (HaH) and control (B&M). The primary analysis was an intention‐to‐treat non‐inferiority analysis of the primary outcome, which was a composite of 30‐day all‐cause mortality and unplanned readmissions. Secondary outcomes included 30‐day readmission, all‐cause mortality, and patient experience. Results The mean age was 67.8 (standard deviation [SD] 16.3) years, and 52.2% were female. The primary outcome occurred in 99 (17.3%) HaH patients and 114 (19.8%) B&M patients (odds ratio [OR] 0.85, 95% confidence interval [CI] 0.63–1.14, p = .28), meeting the non‐inferiority criterion. Thirty‐day unplanned readmission occurred in 84 (14.7%) HaH patients and 101 (17.5%) B&M patients (OR 0.81, 95% CI 0.59–1.11, p = .19). Thirty‐day all‐cause mortality occurred in 25 (4.4%) HaH patients and 19 (3.3%) B&M patients (OR 1.34, 95% CI 0.73–2.46, p = .35). No HaH patients died while receiving their hospital care at home. HaH program was associated with a higher likelihood of patients reporting feeling extremely comfortable or very comfortable (84.4% HaH; 60.9% B&M, p = .001). Conclusion A hybrid HaH model is a safe and comfortable alternative to traditional B&M hospital care.

AbstractObjectiveLow‐grade parotid malignancies have high overall survival rates; however, controversy remains about the appropriate extent of surgery. We aim to explore the trends in the extent of parotidectomy performed over time in low‐grade parotid malignancies in the United States, with a hypothesis that there has been a trend towards less aggressive surgery.Study DesignRetrospective cohort study of all low‐grade (grade I) acinic cell carcinoma (ACC) and mucoepidermoid carcinoma (MEC) in the Surveillance, Epidemiology, and End Results (SEER) from 2004 to 2020.SettingGeographic areas served by SEER.MethodsTrends were assessed using Cochran‐Armitage tests and logistic regression; Kaplan‐Meier survival curves were used to analyze overall and cancer‐specific survival, and chi‐square tests were used to analyze patient characteristics.ResultsIn total, 1288 patients were identified (916 MEC; 372 ACC). Most patients (n = 772, 60%) were non‐Hispanic white, with an average age of 50.6 years and had a slight female predominance (1.58:1). Most of the cohort presented with tumor stage T1 or T2 (84%), N0 (90.1%), and M0 (96.9%). Treatment with total parotidectomy decreased significantly (34.6 vs 17.7%, P = .02) whereas sacrificing the facial nerve (FN) slightly decreased (20 vs 15.7%, P = .1). A significant increase in N0 patients (71%‐94%, P < .0001) was observed, whereas T staging remained stable (61%‐64%, P = .3). Overall, both ACC and MEC had excellent cancer‐specific survival.ConclusionOver the last 17 years, there has been a significant de‐escalation in the extent of parotidectomy for low‐grade parotid malignancy in the United States.

BACKGROUND: Children continue to undergo right hemicolectomy (RHC) for neuroendocrine tumors (NET) of the appendix based on adult guidelines. Appendectomy alone is recommended for the pediatric population; however, there are no data on safety of this approach in the setting of positive margins. This study aimed to determine the association between tumor characteristics and survival in a national cohort, hypothesizing that survival would be excellent despite high-risk features including positive margins on appendectomy. STUDY DESIGN: Patients 18 years of age or younger with NET of the appendix were identified in the National Cancer Database from 2004 to 2022 using ICD-O-3 codes. Characteristics of patients who underwent definitive appendectomy vs RHC were compared using chi-square tests. Five-year survival was determined for appendectomy patients with and without high-risk size, margin, and lymph node (LN) features. RESULTS: Of 1,339 patients, 1,156 (86%) underwent appendectomy and 183 (14%) RHC. Median age in both groups was 15 (13 to 17) years. Patients who underwent RHC had larger tumors (24% vs 4%, greater than 2 cm, p < 0.001), more lymphovascular invasion (31% vs 10%, p < 0.001), and were more likely to undergo LN assessment (82% vs 10%, p < 0.001) with a higher LN positivity rate (31% vs 16%, p = 0.006). There was no difference in margins status (p = 0.76). The 5- and 10-year survival was excellent regardless of tumor characteristics for patients overall (99.9% and 99.4%, respectively) and for those who underwent definitive appendectomy (99.9% and 99.2%). CONCLUSIONS: These data further support appendectomy as definitive management for children with appendiceal NET. Additional resection does not confer a survival benefit even in the setting of positive margins.

Background: Traditional Medicare (TM) claims data are widely used by researchers and registries to report survivorship following total knee arthroplasty (TKA). The purpose of the present study was to investigate whether the mass exodus of patients from TM to Medicare Advantage (MA) has compromised the fidelity of TM data. Methods: We identified 11,717 Medicare-eligible patients (15,282 knees) who had undergone primary TKA from 2000 to 2020 at a single institution. Insurance type was analyzed, and 84% of TKAs were covered by TM. The rates of survivorship free from revision or reoperation were calculated for patients with TM coverage. The same survivorship end points were recalculated after censoring of patients who transitioned to MA after primary TKA, thereby modeling the impact of losing patients from the TM dataset. Differences in survivorship were compared. The mean duration of follow-up was 10 years. Results: From 2000 to 2020, there was a decrease in TM insurance (from 94% to 68%) and a corresponding increase in MA insurance (from 0% to 19%) among patients undergoing TKA. Following TKA, 25% of patients with TM coverage switched to MA. For patients with TM at the time of surgery, the 15-year rates of survivorship free from any reoperation or revision were 90% and 96%, respectively. When patients were censored upon transition from TM to MA, the 15-year rates of survivorship free from any reoperation (92% versus 90%; hazard ratio [HR] = 1.2; p = 0.001) or any revision (97% versus 96%; HR = 1.3; p = 0.002) were significantly higher. Conclusions: One in 4 patients left TM for MA after primary TKA, effectively making them lost to follow-up within TM datasets. The mass exodus of patients out of TM resulted in falsely elevated estimates of survivorship free from reoperation and from revision, with increasing divergence in survivorship over time, when MA data were excluded. As MA continues to grow, efforts to incorporate these data will become increasingly important. Level of Evidence: Therapeutic Level III .

Objective: To characterize the relationship between surgeon-staff familiarity and the time required to perform an operation. Summary Background Data: The clinical and operational efficiency of operating rooms is a driver of hospital finances and patient outcomes. Surgeon-staff familiarity is an important focus for quality improvement and process optimization. Methods: A retrospective cohort study was performed analyzing operations performed at 4 academic hospitals between July 1, 2019 and December 31, 2023. Exclusion criteria (urgent operations, 2-specialty cases, low surgeon/specialty volume in data set, scheduled length > 8 hours) were applied to limit heterogeneity. The exposure of interest was familiarity between the surgeon and the allied health staff (scrub technicians and circulating nurses) present during an operation (represented as the median staff experience with the index surgeon in the previous 180 d). The primary outcome was whether the actual case length was (vs. was not) 10% shorter than the scheduled case length (“shorter case length”). A secondary outcome was the quantification of the difference between the observed and expected case length and whether the surgical time (cut-close) was shorter. Results: A total of 257,645 operations performed by 25 different specialties comprised the analyzed cohort. Higher levels of surgeon-staff familiarity were associated with a higher likelihood of a shorter case length (observed:expected ratio = 1.16 [1.14–1.18] for high/high levels of familiarity, compared with 0.90 [0.88–0.91] for low/low levels of familiarity). Greater familiarity was also associated with case lengths that were shorter relative to scheduled case length (high/high levels of familiarity 8.7% shorter than low/low levels, P < 0.001). Within the 4 most common types of cases, those operations performed by teams with higher levels of familiarity had shorter surgical times (cut-to-close). Conclusions: This study found that operations were more efficiently performed when the scrub technician and circulating nurse staff had a greater recent experience with the primary surgeon. Surgical team familiarity should be considered a focus of operational and clinical excellence.

ABSTRACTIntroductionThe outcomes of completion thyroidectomy are not well‐documented. The study aim is to compare the risks of total thyroidectomy (TT), thyroid lobectomy (TL), and completion thyroidectomy (CT) using a large multi‐institutional database.MethodsAll cases of thyroidectomy without lymphadenectomy were identified using the CESQIP national database (2013–2023). Completion thyroidectomy was defined as contralateral lobectomy following previous lobectomy. Outcomes were examined including hematoma requiring evacuation, vocal cord dysfunction on post‐op laryngoscopy, and clinical concern for hypoparathyroidism.ResultsAmong 33,154 cases, TT, TL, and CT were performed in 19,057 (57%), 13,135 (40%) and 962 (3%), respectively. 30‐day hematoma rates were overall low: 135 (0.8%) in TT, 57 (0.5%) in TL, and < 10 (0.7%) in CT (p < 0.01). 30‐day vocal cord dysfunction was documented in 233 (1.4%), 159 (1.3%), and < 10 (1.0%) for TT, TL, and CT, respectively (p = 0.65). Temporary hypoparathyroidism was more common after TT than CT (989 (6%) versus 20 (2%), p < 0.01). Among 16,311 (49%) patients with reported long‐term outcomes, there were no differences in the rates of vocal cord dysfunction by type of operation (p = 0.34). However, long‐term hypoparathyroidism was more likely after TT than CT (237 (2.5%) versus < 10 (0.7%), p < 0.01).ConclusionIn this multi‐institutional endocrine surgery database, the reported long‐term complication rates after completion thyroidectomy were the same as for first‐time thyroid lobectomy. However, clinical hypoparathyroidism was 2.5‐fold more likely for total thyroidectomy than for completion thyroidectomy at 30‐days and remained 3.7‐fold higher in the long term suggesting that completion thyroidectomy does not pose a higher risk of complications.

Abstract Given the heterogeneous clinical behavior of pancreatic neuroendocrine tumors (pNETs), improved prognostic markers are needed to guide management and post‐resection surveillance. Patients who underwent resection of large (≥3 cm) sporadic well‐differentiated pNETs from 2000 to 2019 were identified. The Ki‐67 proliferation index was determined using immunohistochemistry, and alternative lengthening of telomeres (ALT) status was assessed using fluorescence in situ hybridization. Recurrence‐free and overall survival were estimated using Kaplan–Meier analysis. Multivariable Cox regression analysis evaluated factors associated with recurrence‐free survival. A total of 106 patients were identified. ALT was positive in 57 (54%) and negative in 49 (46%). Ki‐67 was ≥3% in 74 (70%) and <3% in 32 (30%). Tumors with Ki‐67 ≥3% were more likely to be ALT positive (61% vs. 38%, p = .046). Stratifying by ALT status and Ki‐67 proliferation index, median recurrence‐free survival was 4.6 years for patients with ALT‐positive/Ki‐67 ≥3% tumors, 3.1 years for patients with ALT‐positive/Ki‐67 <3% tumors, 12.4 years for patients with ALT‐negative/Ki‐67 ≥3% tumors, and 20.2 years for patients with ALT‐negative/Ki‐67 <3% tumors ( p < .001). Initial recurrence was distant in 82% and locoregional in 18%. Across all groups, overall survival was similar ( p = .19). In multivariable analysis, advanced age, ALT positivity, perineural invasion, and lymph node metastases were associated with increased recurrence risk (all p < .05). ALT and Ki‐67 provide complementary information on post‐resection recurrence risk, which can guide subsequent surveillance and management strategies. These data support the incorporation of ALT testing into routine clinical practice.
