Judgment Errors in Surgical Care.

BACKGROUND: Human error is impossible to eliminate, particularly in systems as complex as healthcare. The extent to which judgment errors in particular impact surgical patient care or lead to harm is unclear. STUDY DESIGN: The American College of Surgeons NSQIP (2018) procedures from a single institution with 30-day morbidity or mortality were examined. Medical records were reviewed and evaluated for judgment errors. Preoperative variables associated with judgment errors were examined using logistic regression. RESULTS: Of the surgical patients who experienced a morbidity or mortality, 18% (31 of 170) experienced an error in judgment during their hospitalization. Patients with hepatobiliary procedure (odds ratio [OR] 5.4 [95% CI 1.23 to 32.75], p = 0.002), insulin-dependent diabetes (OR 4.8 [95% CI 1.2 to 18.8], p = 0.025), severe COPD (OR 6.0 [95% CI 1.6 to 22.1], p = 0.007), or with infected wounds (OR 8.2 [95% CI 2.6 to 25.8], p < 0.001) were at increased risk for judgment errors. CONCLUSIONS: Specific procedure types and patients with certain preoperative variables had higher risk for judgment errors during their hospitalization. Errors in judgment adversely impacted the outcomes of surgical patients who experienced morbidity or mortality in this cohort. Preventing or mitigating errors and closely monitoring patients after an error in judgment is prudent and may improve surgical safety.

A Novel Thyroid Ultrasound Proficiency Metric Designed Through a Multidisciplinary Delphi Approach.

BACKGROUND: Thyroid ultrasounds extend surgeons' outpatient capabilities and are essential for operative planning. However, most residents are not formally trained in thyroid ultrasound. The purpose of this study was to create a novel thyroid ultrasound proficiency metric through a collaborative Delphi approach. METHODS: Clinical faculty experienced in thyroid ultrasound participated on a Delphi panel to design the thyroid Ultrasound Proficiency Scale (UPS-Thyroid). Participants proposed items under the categories of Positioning, Technique, Image Capture, Measurement, and Interpretation. In subsequent rounds, participants voted to retain, revise, or exclude each item. The process continued until all items had greater than 70% consensus for retention. The UPS-Thyroid was pilot tested across 5 surgery residents with moderate ultrasound experience. Learning curves were assessed with cumulative sum. RESULTS: Three surgeons and 4 radiologists participated on the Delphi panel. Following 3 iterative Delphi rounds, the panel arrived at >70% consensus to retain 14 items without further revisions or additions. The metric included the following items on a 3-point scale for a maximum of 42 points: Positioning (1 item), Technique (4 items), Image Capture (2 items), Measurement (2 items), and Interpretation (5 items). A pilot group of 5 residents was scored against a proficiency threshold of 36 points. Learning curve inflection points were noted at between 4 to 7 repetitions. CONCLUSIONS: A multidisciplinary Delphi approach generated consensus for a thyroid ultrasound proficiency metric (UPS-Thyroid). Among surgery residents with moderate ultrasound experience, basic proficiency at thyroid ultrasound is feasible within 10 repetitions.

Errors in Surgery: A Case Control Study.

OBJECTIVE: While errors can harm patients they remain poorly studied. This study characterized errors in the care of surgical patients and examined the association of errors with morbidity and mortality. BACKGROUND: Errors have been reported to cause <10% or >60% of adverse events. Such discordant results underscore the need for further exploration of the relationship between error and adverse events. METHODS: Patients with operations performed at a single institution and abstracted into the American College of Surgeons National Surgical Quality Improvement Program from January 1, 2018, to December 31, 2018 were examined. This matched case control study comprised cases who experienced a postoperative morbidity or mortality. Controls included patients without morbidity or mortality, matched 2:1 using age (±10 years), sex, and Current Procedural Terminology (CPT) group. Two faculty surgeons independently reviewed records for each case and control patient to identify diagnostic, technical, judgment, medication, system, or omission errors. A conditional multivariable logistic regression model examined the association between error and morbidity. RESULTS: Of 1899 patients, 170 were defined as cases who experienced a morbidity or mortality. The majority of cases (n=93; 55%) had at least 1 error; of the 329 matched control patients, 112 had at least 1 error (34%). Technical errors occurred most often among both cases (40%) and controls (23%). Logistic regression demonstrated a strong independent relationship between error and morbidity (odds ratio=2.67, 95% confidence interval: 1.64-4.35, P <0.001). CONCLUSION: Errors in surgical care were associated with postoperative morbidity. Reducing errors requires measurement of errors.

New endocrine fellowship programs do not decrease the endocrine surgery experience of residents in co-located general surgery programs.

BACKGROUND: New pediatric and vascular surgical fellowship programs decrease resident operative experience in those subspecialties in co-located general surgery programs.After 2 decades of increases, the mean number of endocrine surgery cases performed by general surgery residents nationally has decreased since 2010 to 2011. We hypothesized that new endocrine surgery fellowship programs lead to a decrease in the number of endocrine surgery cases performed by co-located general surgery residents and may be a contributing factor in the recent national decline in endocrine surgery cases performed by general surgery residents. METHODS: Endocrine surgery fellowship programs associated with a single, Accreditation Council of Graduate Medical Education-accredited general surgery program that have completed training of 1 fellow by the 2014-2015 academic year were identified. Endocrine surgery cases performed by general surgery residents who completed co-located general surgery programs from 2002 to 2003 through 2017 to 2018 were recorded. Descriptive statistics are shown as mean ± standard deviation. Statistical significance was calculated using the Mann-Whitney U Test. RESULTS: In the 13 general surgery programs with 5 years of case log data after the matriculation of the first fellow, the mean number of total endocrine surgery cases/resident increased from 47 ± 23 in year 0 to 57 ± 25 in year 5 (z-score = 2.53; P < .05). CONCLUSION: New endocrine surgery fellowship programs do not decrease the endocrine surgery cases performed by general surgery residents and have not contributed to the national decline in endocrine surgery cases by general surgery residents.

The ups and downs of general surgery resident experience in endocrine surgery: Analysis of 30 years of ACGME graduate case logs.

BACKGROUND: The aim of this study was to determine trends in the experience of general surgery residents with endocrine surgery cases. METHODS: American Association of Endocrine Surgeons national general surgery case logs from 1989 through 2019 were reviewed. The numbers of individuals completing residency and the mean and median number of endocrine surgery cases by type and by level of operating resident surgeon were abstracted from annual data and analyzed. Descriptive statistics and linear regression analyses were performed modeling endocrine surgery cases over time and stratified by procedure type and resident level. RESULTS: The number of individuals completing general surgery residency each year increased from 981 to 1,219 (P < .001). The average total number of endocrine surgery cases performed increased from 17 to 33.2 (P < .001) but has declined since its peak at 36.9 in 2010 to 2011 (P = .014). Thyroid operations increased from 11.4 to 19.8 (P < .001) but peaked at 23.5 in 2010 to 2011 and have since declined (P < .001). Parathyroid operations more than doubled from 4.2 to 9.7 (P < .001). Adrenal operations increased from 1 to 2.2 (P < .001) and pancreatic endocrine operations increased from 0.2 to 1.5 (P < .001). Surgeon Chief endocrine surgery cases peaked at 14.4 in 2003 to 2004 but have since declined by 22.2% (P < .001). Surgeon Junior endocrine surgery cases increased overall (P < .001) but peaked at 22.8 in 2011 to 2012. There was increasing heterogeneity over time in trainee experience (P < .001). CONCLUSION: After having increased for 2 decades, the number of endocrine surgery cases performed by general surgery residents is currently in decline. Possible contributing factors include growth in the number of general surgery residents, variable and narrowed case mix, and encroachment by other learners.

Chromosome-level de novo assembly of the pig-tailed macaque genome using linked-read sequencing and HiC proximity scaffolding.

BACKGROUND: Macaque species share >93% genome homology with humans and develop many disease phenotypes similar to those of humans, making them valuable animal models for the study of human diseases (e.g., HIV and neurodegenerative diseases). However, the quality of genome assembly and annotation for several macaque species lags behind the human genome effort. RESULTS: To close this gap and enhance functional genomics approaches, we used a combination of de novo linked-read assembly and scaffolding using proximity ligation assay (HiC) to assemble the pig-tailed macaque (Macaca nemestrina) genome. This combinatorial method yielded large scaffolds at chromosome level with a scaffold N50 of 127.5 Mb; the 23 largest scaffolds covered 90% of the entire genome. This assembly revealed large-scale rearrangements between pig-tailed macaque chromosomes 7, 12, and 13 and human chromosomes 2, 14, and 15. We subsequently annotated the genome using transcriptome and proteomics data from personalized induced pluripotent stem cells derived from the same animal. Reconstruction of the evolutionary tree using whole-genome annotation and orthologous comparisons among 3 macaque species, human, and mouse genomes revealed extensive homology between human and pig-tailed macaques with regards to both pluripotent stem cell genes and innate immune gene pathways. Our results confirm that rhesus and cynomolgus macaques exhibit a closer evolutionary distance to each other than either species exhibits to humans or pig-tailed macaques. CONCLUSIONS: These findings demonstrate that pig-tailed macaques can serve as an excellent animal model for the study of many human diseases particularly with regards to pluripotency and innate immune pathways.

Community level socioeconomic status association with surgical outcomes and resource utilisation in a regional cohort: a prospective registry analysis.

BACKGROUND: Socioeconomic status affects surgical outcomes, however these factors are not included in clinical quality improvement data and risk models. We performed a prospective registry analysis to determine if the Distressed Communities Index (DCI), a composite socioeconomic ranking by zip code, could predict risk-adjusted surgical outcomes and resource utilisation. METHODS: All patients undergoing surgery (n=44,451) in a regional quality improvement database (American College of Surgeons-National Surgical Quality Improvement Program ACS-NSQIP) were paired with DCI, ranging from 0-100 (low to high distress) and accounting for unemployment, education level, poverty rate, median income, business growth and housing vacancies. The top quartile of distress was compared to the remainder of the cohort and a mixed effects modeling evaluated ACS-NSQIP risk-adjusted association between DCI and the primary outcomes of surgical complications and resource utilisation. RESULTS: A total of 9369 (21.1%) patients came from severely distressed communities (DCI >75), who had higher rates of most medical comorbidities as well as transfer status (8.4% vs 4.8%, p<0.0001) resulting in higher ACS-NSQIP predicted risk of any complication (8.0% vs 7.1%, p<0.0001). Patients from severely distressed communities had increased 30-day mortality (1.8% vs 1.4%, p=0.01), postoperative complications (9.8% vs 8.5%, p<0.0001), hospital readmission (7.7 vs 6.8, p<0.0001) and resource utilisation. DCI was independently associated with postoperative complications (OR 1.07, 95% CI 1.04 to 1.10, p<0.0001) as well as resource utilisation after adjusting for ACS-NSQIP predicted risk CONCLUSION: Increasing Distressed Communities Index is associated with increased postoperative complications and resource utilisation even after ACS-NSQIP risk adjustment. These findings demonstrate a disparity in surgical outcomes based on community level socioeconomic factors, highlighting the continued need for public health innovation and policy initiatives.

Effect of Travel Time for Thyroid Surgery on Treatment Cost and Morbidity.

Regionalizing surgical care to high-volume centers has improved outcomes for endocrine surgery. This shift is associated with increased travel time, costs, and morbidity within certain patient populations. We examined travel time-related differences in demographics, health-care utilization, thyroid-specific disease, and cost for patients undergoing thyroid surgery at a single high-volume center. Data were extracted from the 2005 to 2014 ACS-NSQIP and clinical data repository for patients undergoing thyroid surgery. Travel times between patients' home address and the hospital were calculated using Google Earth under assumptions of standard road conditions and speed restrictions. Travel time was divided into <2 hours versus ≥2 hours. Primary outcomes were hospital cost and 30-day morbidity. Factors associated with travel time and primary outcomes were analyzed using appropriate bivariate tests and multivariable regression modeling. A total of 1046 thyroid procedures were included, with median (IQR) travel time of 68.8 (40.1-107.2) minutes. Eight hundred forty-seven (80.9%) patients traveled <2 hours compared with 199 (19.1%) traveled ≥2 hours. Patients traveling ≥2 hours were more likely to have complex thyroid disease (37.7% vs 27.6%, P = 0.005), uninsured status (31.1% vs 11.8%, P < 0.001), lower preoperative morbidity risk (2.3% vs 2.7%, P = 0.02), and longer length of stay (1.21 vs 1.07 days, P = 0.04), but similar median operative times (163 vs 165 minutes, P = 0.89). Average cost was higher for patients traveling ≥2 hours ($7300 vs $6846 [2014 USD], P = 0.05). Despite observed patient differences, hospital costs and postoperative morbidity did not differ after adjustment. Existing management practices and the nature of the disease process may be protective against the potential negative effects of regionalization.

Impact of New Vascular Fellowship Programs on Vascular Surgery Operative Volume of Residents in Associated General Surgery Programs.

BACKGROUND: General surgery (GS) resident vascular surgery (VS) operations have declined significantly in the last 15 years. We hypothesized that initiation of VS fellowship programs (VSFPs) contributes to that decline. This study examined the effect of establishing new VSFPs on VS case volumes of residents in associated GS programs. STUDY DESIGN: General surgery programs were reviewed if associated with VSFPs accredited since July 1, 2002 that had 1 or more matriculants (GS case logs only available since 2002 to 2003). Total VS cases by residents in those programs was analyzed before and after matriculation of first fellow into the associated VSFP. RESULTS: Twenty-two programs were available for analysis. General surgery case-log data were available variably from 0 to 14 years before and 0 to 14 years after first fellows in the associated VSFPs. In 12 programs with 4 years of data before and after matriculation of associated VSFPs' first fellows, VS cases increased from 109.6 ± 32.4 cases to 143.65 ± 78.15 cases in 4 years before matriculation (p = 0.008) of VS fellows and then declined from 143.65 to 114.04 ± 46.97 in 4 years after (p = 0.0134). In all 16 programs with 4 years of data after matriculation of the associated VSFP's first fellow, VS cases declined from 123.37 ± 71.42 to 103.23 ± 44.35 (p = 0.0232). CONCLUSIONS: New VSFPs diminished peak VS operative volume of residents in associated GS programs, thereby contributing to declining national average number of VS cases done by GS residents. Nevertheless, resident VS case volumes remained robust in most GS programs associated with new VSFPs. Additional study is required to determine both resident perception and overall impact of VSFPs on associated GS training.

Influence of Gender on Surgical Residency Applicants' Recommendation Letters.

BACKGROUND: Implicit bias has been documented in candidate selection within academic medicine. Gender bias is exposed when writers systematically use different language to describe attributes of male and female applicants. This study examined the presence of gender bias in recommendation letters for surgical residency candidates. STUDY DESIGN: Recommendation letters for 2016 to 2017 surgery resident applicants selected for interview at an academic institution were analyzed using qualitative text analysis, quantitative text mining, and topic modeling. Dedoose, QDA Miner, and RStudio analytic software were used for analysis. RESULTS: There were 332 letters of recommendation for 89 applicants (51% male) analyzed. Of 265 letter writers, 86% were male, 21% chairs, and 50% professors. Average word count was 404. Letter writers for male compared with female applicants had a significantly higher average word count (male = 421, SD 144; female = 388, SD 140, p = 0.035). Standout adjectives (eg exceptional), reference to awards, achievement, ability, hardship, leadership, scholarship, and use of applicant's name were most often applied to male applicants. Comments on positive general terms (eg delightful), grindstone words (eg hard-working), physical description, doubt raisers, and work ethic were most often applied to female applicants. Topic modeling and term frequencies revealed achievement words (performance, career, leadership, and knowledge) used more often with male applicants, while caring words (care, time, patients, and support) were used more often with female applicants. CONCLUSIONS: Gendered differences examined through language and text exist in surgical residents' recommendation letters. Implementing tools to help faculty write recommendation letters with meaningful content and editing letters for reflections of stereotypes may improve the resident selection process by reducing bias.

Resident-Specific Morbidity Reduced Following ACS NSQIP Data-Driven Quality Program.

BACKGROUND: The Accreditation Council for Graduate Medical Education Milestone Project for general surgery provided a more robust method for developing and tracking residents' competence. This framework enhanced systematic and progressive development of residents' competencies in surgical quality improvement. STUDY DESIGN: A 22-month interactive, educational program based on resident-specific surgical outcomes data culminated in a quality improvement project for postgraduate year 4 surgery residents. Self- assessment, quality knowledge test, and resident-specific American College of Surgeons National Surgical Quality Improvement Program Quality In-Training Initiative morbidity were compared before and after the intervention. RESULTS: Quality in-training initiative morbidity decreased from 25% (82/325) to 18% (93/517), p = 0.015 despite residents performing more complex cases. All participants achieved level 4 competency (4/4) within the general surgery milestones improvement of care, practice-based learning and improvement competency. Institutional American College of Surgeons National Surgical Quality Improvement Program general surgery morbidity improved from the ninth to the sixth decile. Quality assessment and improvement self-assessment postintervention scores (M = 23.80, SD = 4.97) were not significantly higher than preintervention scores (M = 19.20, SD = 5.26), p = 0.061. Quality Improvement Knowledge Application Tool postintervention test scores (M = 17.4, SD = 4.88), were not significantly higher than pretest scores (M = 13.2, SD = 1.92), p = 0.12. CONCLUSION: Sharing validated resident-specific clinical data with participants was associated with improved surgical outcomes. Participating fourth year surgical residents achieved the highest score, a level 4, in the practice based learning and improvement competency of the improvement of care practice domain and observed significantly reduced surgical morbidity for cases in which they participated.

FARNA: knowledgebase of inferred functions of non-coding RNA transcripts.

Non-coding RNA (ncRNA) genes play a major role in control of heterogeneous cellular behavior. Yet, their functions are largely uncharacterized. Current available databases lack in-depth information of ncRNA functions across spectrum of various cells/tissues. Here, we present FARNA, a knowledgebase of inferred functions of 10,289 human ncRNA transcripts (2,734 microRNA and 7,555 long ncRNA) in 119 tissues and 177 primary cells of human. Since transcription factors (TFs) and TF co-factors (TcoFs) are crucial components of regulatory machinery for activation of gene transcription, cellular processes and diseases in which TFs and TcoFs are involved suggest functions of the transcripts they regulate. In FARNA, functions of a transcript are inferred from TFs and TcoFs whose genes co-express with the transcript controlled by these TFs and TcoFs in a considered cell/tissue. Transcripts were annotated using statistically enriched GO terms, pathways and diseases across cells/tissues based on guilt-by-association principle. Expression profiles across cells/tissues based on Cap Analysis of Gene Expression (CAGE) are provided. FARNA, having the most comprehensive function annotation of considered ncRNAs across widest spectrum of human cells/tissues, has a potential to greatly contribute to our understanding of ncRNA roles and their regulatory mechanisms in human.

Clinical efficacy of 2-phase versus 4-phase computed tomography for localization in primary hyperparathyroidism.

BACKGROUND: Four-dimensional computed tomography is being used increasingly for localization of abnormal glands in primary hyperparathyroidism. We hypothesized that compared with traditional 4-phase imaging, 2-phase imaging would halve the radiation dose without compromising parathyroid localization and clinical outcomes. METHODS: A transition from 4-phase to 2-phase imaging was instituted between 2009 and 2010. A pre-post analysis was performed on patients undergoing operative treatment with a parathyroid protocol computed tomography, and relevant data were correlated with operative findings. Sensitivity, positive predictive value, technical success, and cure rates were calculated. The Fisher exact test or χ(2) test assessed the significance of 2-phase and 4-phase imaging and operative findings. RESULTS: Twenty-seven patients had traditional four-dimensional computed tomography and 35 had modified 2-phase computed tomography. Effective radiation doses were 6.8 mSy for 2-phase and 14 mSv for 4-phase. Four-phase computed tomography had a sensitivity and positive predictive value of 93% and 96%, respectively. Two-phase computed tomography had a comparable sensitivity and positive predictive value of 97% and 94%, respectively. Eight patients with discordant imaging had an average parathyroid weight of 240 g compared with 1,300 g for all patients. Technical surgical success (90% for 4-phase computed tomography versus 91% 2-phase computed tomography) and normocalcemia rates at 6 months (88% for both) did not differ between computed tomography protocols. Computed tomography correctly predicted multiglandular disease and localization for reoperations in 88% and 90% of cases, respectively, with no difference by computed tomography protocol. CONCLUSION: With regard to surgical outcomes and localization, 2-phase parathyroid computed tomography is equivalent to 4-phase for parathyroid localization, including small adenomas, reoperative cases, and multiglandular disease. Two-phase parathyroid computed tomography for operative planning should be considered to avoid unnecessary radiation exposure.

Interprofessional training enhances collaboration between nursing and medical students: A pilot study.

BACKGROUND: Effective collaboration among healthcare providers is an essential component of high-quality patient care. Interprofessional education is foundational to ensuring that students are prepared to engage in optimal collaboration once they enter clinical practice particularly in the care of complex geriatric patients undergoing surgery. STUDY DESIGN: To enhance interprofessional education between nursing students and medical students in a clinical environment, we modeled the desired behavior and skills needed for interprofessional preoperative geriatric assessment for students, then provided an opportunity for students to practice skills in nurse/physician pairs on standardized patients. This experience culminated with students performing skills independently in a clinic setting. RESULTS: Nine nursing students and six medical students completed the pilot project. At baseline and after the final clinic visit we administered a ten question geriatric assessment test. Post-test scores (M=90.33, SD=11.09) were significantly higher than pre-test scores (M=72.33, SD=12.66, t(14)=-4.50, p<0.001. Nursing student post-test scores improved a mean of 22.0 points and medical students a mean of 11.7 points over pre-test scores. Analysis of observational notes provided evidence of interprofessional education skills in the themes of shared problem solving, conflict resolution, recognition of patient needs, shared decision making, knowledge and development of one's professional role, communication, transfer of interprofessional learning, and identification of learning needs. CONCLUSIONS: Having nursing and medical students "learn about, from and with each other" while conducting a preoperative geriatric assessment offered a unique collaborative educational experience for students that better prepares them to integrate into interdisciplinary clinic teams.

Elective laparoscopic adrenalectomy outcomes in 1099 ACS NSQIP patients: identifying candidates for early discharge.

This study evaluates the risk of complications associated with elective laparoscopic adrenalectomy (LA) as reported in a national dataset. We hypothesize that the risk for major complication is associated with identifiable perioperative variables. This information may aid in understanding who safely could be discharged early after surgery, including same-day discharge. Elective LA from 2009 to 2010 American College of Surgeons National Surgical Quality Improvement Program Participant Use File were reviewed. A priori selection of likely risk factors for complications was assessed for their association with morbidity. Sequential bivariable logistic regression was used to measure the statistical significance of each risk factor's observed association with the occurrence of major morbidity after surgery. The potential for multiple comparisons bias was accounted for by using a high threshold (P < 0.01) for identifying statistically significant associations. One thousand ninety-nine patients were identified. The 30-day mortality rate was 0.18 per cent, and 4.8 per cent of patients experienced a major morbidity within 30 days of surgery. Return to the operating room occurred in 1.46 per cent of cases. Statistically significant associations occurred for 15 patient characteristics at P < 0.05. Diabetes, nonindependent functional status before surgery, American Society of Anesthesiologists classification >2, and operative time were statistically significant at P < 0.01. Complications are rare events among elective LA patients. However, several readily identifiable patient characteristics are associated with the occurrence of complications among these patients. These patient characteristics should be taken into account when considering future trials of early discharge after LA, including same-day discharge.

Risk factors for 30-day hospital readmission after thyroidectomy and parathyroidectomy in the United States: An analysis of National Surgical Quality Improvement Program outcomes.

BACKGROUND: The 30-day readmission rate is a quality metric under the Affordable Care Act. Readmission rates after thyroidectomy and parathyroidectomy and associated factors remain ill-defined. We evaluated patient and perioperative factors for association with readmission after thyroidectomy and parathyroidectomy. METHODS: The American College of Surgeons National Surgical Quality Improvement Program Participant Use File (2011) data for thyroid (n = 3,711) and parathyroid (n = 3,358) resections were analyzed. Patient- and operation-related factors were assessed by univariate and multivariate analyses. RESULTS: Among 7,069 patients, 30-day readmission rate was 4.0%: 4.1% after thyroidectomy and 3.8% after parathyroidectomy. Significant associations for 30-day readmission included declining functional status (odds ratio [OR], 6.4-10.1), preoperative hemodialysis (OR, 2.6; 95% CI, 1.5-4.7), malnutrition (OR, 3.4; 95% CI, 1.2-10.1), increasing American Society of Anesthesiologists class (OR 1.3-4.7), unplanned reoperation (OR, 61.6), and length of stay (LOS) <24 hours (OR, 0.61; 95% CI, 0.45-0.85; all P < .05). Readmission was associated with greater total and postoperative LOS and major postoperative complications, including renal insufficiency (all P < .01). CONCLUSION: Thirty-day readmission after cervical endocrine resection occurs in 4% of patients. Discharge within 24 hours of operation does not affect the likelihood of readmission. Risk factors for readmission are multifactorial and driven by preoperative conditions. Decreasing the index hospital stay and preventing major postoperative complications may decrease readmissions and improve quality metrics.

Adrenalectomy for adrenal-mediated hypertension: National Surgical Quality Improvement Program analysis of an institutional experience.

Adrenal-mediated hypertension (AMH) has been increasingly treated by laparoscopic adrenalectomy (LA). Metabolic derangements in patients with AMH could result in perioperative complications and mortality. Long-term operative and clinical outcomes after laparoscopic treatment of AMH have not been evaluated using large clinical databases. The institutional National Surgical Quality Improvement Program (NSQIP) data for patients undergoing adrenalectomy for AMH between 2002 and 2012 were reviewed. Patient demographics, perioperative variables, and outcomes were analyzed and compared with national NSQIP adrenalectomy data. Improvement in AMH was recorded when discontinuation or reduction of antihypertensive medication occurred or with a decrease of blood pressure on the preoperative antihypertensive regimen. Ninety-four patients underwent adrenalectomy. There were 48 patients with pheochromocytoma (PHE) and 46 patients with aldosterone-producing adenoma (APA). Eighty-five patients (90%) were taking antihypertensive medications preoperatively compared with 36 patients (38%) postoperatively (P < 0.0001). Patients with PHE were more likely to discontinue all medications compared with the patients with APA (80 vs 20%, respectively, P < 0.0001). Patients with PHE and APA, respectively, took an average of 2.0 and 3.2 antihypertensive medications preoperatively compared with 0.3 and 1.2 postoperatively. There were no conversions to open procedures or 30-day mortality. Our results were 0 per cent for cerebral vascular accident, 0 per cent for myocardial infarction, and 0.5 per cent for transfusions compared with the national NSQIP data of 0.2, 0, and 6.7 per cent, respectively. Patients presenting with significant AMH including PHE and APA can be effectively and safely treated with LA with minimal complications and with a significant number of patients eliminating or decreasing their need for antihypertensive medications.
