Knowledge gaps and confidence in counseling about aneuploidy screening and testing: A survey of prenatal care clinicians

OBJECTIVES

Comprehensive counseling on prenatal genetic screening and diagnostic testing is challenging for clinicians. We sought to identify baseline clinician knowledge of prenatal genetic screening and diagnostic testing and needs to promote counseling aligned with ACOG recommendations.

METHODS

We performed an anonymous, cross-sectional survey of clinicians at two unaffiliated, tertiary academic institutions to assess the knowledge of, confidence in, and time spent counseling on prenatal genetic screening and diagnostic testing. Stata (Version 17, College Station, TX) was used to perform descriptive statistics. Deductive and inductive coding was used to analyze responses regarding ideal education resources.

RESULTS

The survey response rate was 78% (100/129). Only 36% of respondents correctly answered knowledge questions about prenatal genetic screening and diagnostic testing. A majority, 59% (16/39), of those confident or extremely confident in counseling were unable to answer all questions accurately. Respondents reported a median of 5.6 min (95% CI 4.9-6.4 min) spent counseling. Thematic analysis of free responses revealed desire for visual tools that discuss financial costs and patient values.

CONCLUSIONS

Surveyed clinicians demonstrated deficiencies in knowledge about prenatal genetic counseling. To provide better and more comprehensive care, we noted a desire for the development of formalized resources for clinician and patient education.

Measuring the Impact of a Formalized Surgical Patient Signout System

OBJECTIVE

Routine patient signout within medical teams is an integral component of patient care. Standardized signout systems have shown lowered risks of harm and adverse outcomes to patients, however, many of these systems are difficult to utilize with surgical patients. The purpose of this study was to determine if a standardized surgical signout model would improve resident satisfaction of the signout process and improve resident preparedness for cross-covered services.

DESIGN

A 16-question survey was administered to the surgical residents at a single general surgery residency program. A standardized signout using the mnemonic "CUTS" (Core problem, Updates, Things-to-do, Setbacks) was then implemented in the program. Residents retook the survey at 1, 3, and 6-month intervals to compare resident satisfaction on signout before and after the standardized signout implementation. The descriptive statistics of the survey were analyzed for trends over time, trends by resident training year, and for inferential statistics utilizing subscales.

RESULTS

The descriptive statistics showed that there was an overall trend towards greater resident satisfaction with signout over time with satisfaction increasing from 41.1% to 80% in the general resident cohort. While there were no statistically significant differences, subscale analysis demonstrated greatest trends for improved satisfaction with the CUTS signout model for the PGY1 and PGY5 classes. There was additionally an increased resident preparedness for overnight events and calls, with a 27% increase in perceived preparedness "75% of the time" and a 5.5% increase in perceived preparedness "Always". There was no difference in time spent on signout after the implementation of the model.

CONCLUSIONS

The surgical standardized signout model, CUTS, demonstrated that residents within a single program were more satisfied with signouts, had improved patient understanding and knowledge, and felt increased preparedness for overnight events on cross-covered patients. Further research is needed to determine the impact of the CUTS signout system on patient outcomes.

Enormous Gallstone Discovered in the Setting of Acute-on-chronic Cholecystitis

Biliary disease is a common surgical problem. A unique case of a 53-year-old male with an enormous gallstone precluding safe laparoscopic cholecystectomy is presented. The patient was a 53-year-old male who presented to the emergency department with a 1-day history of abdominal pain for which clinical findings were consistent with acute cholecystitis. A laparoscopic cholecystectomy was attempted, but could not be safely completed due to an enormous gallstone prohibiting attainment of the critical view of safety. The stone measured 12.2 cm × 5.2 cm × 5.2 cm. Although biliary disease is very common and its management well documented, it is rare to uncover stones larger than 5 centimeters in diameter. Clinicians should be aware that enormous gallstones require prompt surgical intervention if discovered in the elective setting to minimize future morbidity should cholecystitis develop; early elective cholecystectomy should be considered upon discovery of large gallstones to prevent encountering a gallbladder with decreased mobilization in the setting of inflamed tissues.

The Effect of Energy Devices, Nerve Monitors, and Drains on Thyroidectomy Outcomes: An American College of Surgeons National Surgical Quality Improvement Project Database Analysis

The effect of energy devices, nerve monitors, and drains on thyroidectomy outcomes has been examined for each tool independently. Current literature supports the routine use of energy devices and nerve monitors and does not support the routine use of drains. The effect of these operative tools is interrelated and should be examined concurrently. The aim of this study was to describe the risk-adjusted effect of each of these tools on thyroidectomy outcomes. A retrospective analysis of 17 985 open thyroidectomy procedures was conducted using the American College of Surgeons National Surgical Quality Improvement Project (ACS-NSQIP) 2016-2018 thyroidectomy targeted procedure database. All open thyroidectomies were included. The risk-adjusted effect of energy devices, nerve monitors, and drains on 30-day outcomes was calculated by multiple logistic regression. Energy devices were associated with a decreased risk of hematoma and decreased extended length of stay without increased risk of hypocalcemia or recurrent laryngeal nerve injury. Nerve monitors were associated with a decreased risk of overall morbidity, decreased recurrent laryngeal nerve injury, and decreased extended length of stay without an increased risk of adverse outcomes. Drains were associated with an increased risk of bleeding, reoperation, and extended length of stay without decreasing hematoma. Our results support the routine use of energy devices and nerve monitors for thyroidectomy and do not support the routine use of drains for thyroidectomy.

Metastatic neuroendocrine tumor with metastases to the right liver in a patient with absent left portal vein

The patient is a 50-year-old female that underwent routine screening colonoscopy during which she was found to have a neuroendocrine tumor in the right colon. The patient underwent computed tomography and magnetic resonance imaging scans that demonstrated metastatic disease in segments 5 and 7 of the liver. Notably, the patient was found to have an absent left portal vein. The metastatic lesions abut the right portal vein; the right portal vein also supplies the left lobe of the liver in place of an absent left portal vein. She underwent a laparoscopic-assisted right hemicolectomy to remove the primary tumor. The patient recovered uneventfully from surgery and is currently being monitored by a multidisciplinary team regarding her metastatic disease. Neuroendocrine tumors can cause long-term effects on health and ultimately death if left untreated. We present a case of metastatic midgut neuroendocrine tumor that has metastasized to the liver in a patient with absent left portal vein.

The Multisplit Ventilator System: Design and Function of a Regulated, Shared Ventilator System

The objective of this paper is to describe the design and function of the multisplit ventilator system (MSVS); an airflow apparatus that enables physicians to provide individualized, isolated ventilation to up to four patients using a single ventilator. Method: The study design is laboratory assessment of the ability of the MSVS to decouple the pressures and resulting tidal volumes between patient limbs in response to adverse extubation (disconnection) or endotracheal tube occlusion of one of the patients in the system. We compare the airflow decoupling of the MSVS against an existing unregulated split ventilator system (USVS) design over eight prototypical patient pairs. Simulated patient prototypes of varying size, minute ventilation requirement, and positive end-expiratory pressure (PEEP) requirement were employed. Result: Respiratory support was developed for varying simulated patient pairs using the MSVS and a USVS. The results demonstrate that patients supported with the MSVS showed significantly smaller changes to tidal volume and PEEP after extubation events, and tidal volume after occlusion events. Conclusion: It was found that the MSVS as a regulated, shared ventilator system effectively buffered simulated patients from clinical changes occurring to another patient connected to the split ventilator. This decoupling ability resulted in significantly smaller changes in delivered support when compared to existing USVS designs, which is an important patient safety consideration if deciding to support multiple patients with a single ventilator.

Predictors and Consequences of Hematoma After Thyroidectomy: An American College of Surgeons National Surgical Quality Improvement Program Database Analysis

BACKGROUND

Hematoma after thyroid surgery is a serious complication. The purpose of this study was to determine the predictors and consequences of hematoma after thyroid surgery.

MATERIALS AND METHODS

A retrospective analysis of 11,552 open thyroidectomies was conducted using the American College of Surgeons National Surgical Quality Improvement Program 2016-2017 main and thyroidectomy-targeted procedure databases. Predictors of hematoma and the effect of hematoma on outcomes were analyzed by multivariate logistic regression, resulting in risk-adjusted odds ratios of hematoma and morbidity/mortality, respectively. Statistical analysis was performed using R version 3.5.1.

RESULTS

We found that male gender (odds ratio 1.71, 95% confidence interval 1.25-2.32; P value 0.0007), Black race (1.89, 1.27-2.77; 0.0014), other race (1.76, 1.23-2.50; 0.0017), hypertension (1.68, 1.20-2.35; 0.0026), diabetes (1.45, 1.00-2.06; 0.0460), and bleeding disorders (3.63, 1.61-7.28; 0.0007) were independent risk factors for postoperative hematoma. The use of an energy device for hemostasis (0.63, 0.46-0.87; 0.0041) was independently associated with decreased hematoma rate. Postoperative hematoma was an independent risk factor for overall morbidity (3.04, 2.21-4.15; <0.0001), hypocalcemia (1.73, 1.08-2.66, 0.0162), recurrent laryngeal nerve injury (2.42, 1.57-3.60, <0.0001), pulmonary morbidity (18.91, 10.13-34.16, <0.0001), wound morbidity (10.61, 5.54-19.02, <0.0001), readmission (5.23, 3.34-7.92, <0.0001), return to operating room (90.73, 62.62-131.97; <0.0001), and length of stay greater than the median (5.10, 3.62-7.15, <0.0001).

CONCLUSIONS

Identified by this study are the predictors of postthyroidectomy hematoma and the consequences thereof. Notably, the use of energy devices for hemostasis was shown to be protective of postoperative hematoma. The results of this study may guide pre- and intra-operative decision-making for thyroidectomy to reduce rates of postoperative hematoma.

Predictors and consequences of recurrent laryngeal nerve injury during open thyroidectomy: An American College of Surgeons National Surgical Quality Improvement Project database analysis

BACKGROUND

Recurrent laryngeal nerve (RLN) injury is a serious complication of thyroidectomy. The purpose of this study is to determine the predictors and consequences of RLN injury during thyroidectomy.

METHODS

A retrospective analysis was conducted using the ACS-NSQIP 2016-2017 main and thyroidectomy targeted procedure databases. Data was analyzed by multivariate logistic regression resulting in risk-adjusted odds ratios of RLN injury and morbidity/mortality.

RESULTS

Age ≥65, black race, neoplastic indication, total or subtotal thyroidectomy, concurrent neck surgery, operation time > median, hypoalbuminemia, and anemia were associated with RLN injury. Use of intraoperative nerve monitoring was associated with decreased RLN injuries. RLN injury is a risk factor for overall morbidity, hypocalcemia, hematoma, pulmonary morbidity, readmission, reoperation, and length of stay > median.

CONCLUSION

Several predictors of RLN injury during thyroidectomy are identified, while use of intraoperative nerve monitoring was associated with a decreased risk of RLN injury. RLN injury is associated increased postoperative complications.

Successful nonoperative management of mycotic radial artery pseudoaneurysm in patient with absent superficial palmar arch

We present the case of a patient in whom a mycotic radial artery false aneurysm developed after removal of a radial arterial line; anatomic constraints precluded simple resection and ligation of the infected artery. The patient was successfully treated nonoperatively by compression bandaging, intravenous antifungals, and serial imaging. This case represents an alternative to standard management of a mycotic aneurysm and demonstrates the importance of an individualized approach to patient care.
