Combined in-person and tele-delivered mobile school clinic: A novel approach for improving access to healthcare during school hours.

AIMS: We report a novel pilot project that allows access to healthcare for children and staff at school via a mobile clinic or telemedicine portal connected to the mobile clinic. The objectives of this pilot project were (a) to perform physicals for children not attached to a primary care physician; (b) to provide medical consultations and treatment for acute illnesses of students and staff, and (c) to lower absenteeism rates among students and staff. METHODS: In 2013, Ronald McDonald House Charities, a non-profit organization, partnered with Children's Hospital of Erlanger to provide a mobile clinic trademarked Ronald McDonald Care Mobile utilising a large, box-style truck equipped with examination rooms and a telemedicine portal. Initially, starting with three elementary schools in Bradley County, Tennessee, USA, the programme rapidly expanded to include schools in five other participating Tennessee counties. Only three schools in Bradley County have the option of in-person visits. All other schools access care via telemedicine portals. Funding is provided through multiple grants and community partners. If a student does have insurance, the insurance carrier is billed for the visit, but students without insurance are treated free of charge. Prior to the 2018-2019 school year, only limited data were collected. RESULTS: Our first goal was to perform physicals for children not attached to a primary care physician. During the 2018-2019 school year, 28 patients presented for a well-child check. However, 16 of these (57%) did not have a primary care physician. Of note, 19% of students presenting for any complaint did not have a primary care physician on file (172 students). All well-child checks were performed in-person on the Care Mobile. Our second goal was to provide medical consultations and treatment for acute illnesses. A total of 1446 persons were seen for sick visits. Of these, 424 were telemedicine visits (352 students and 72 staff), while 1022 were in-person visits. The five most common diagnoses that the nurse practitioner managed during the 2018-2019 school year included acute pharyngitis, acute upper respiratory infection, streptococcal pharyngitis, fever and acute maxillary sinusitis. Finally, our third goal was to lower absenteeism rates. There were 1446 sick person visits (1253 students and 193 staff). Twenty-two per cent of the students (276 persons) returned to class while 74% (142 persons) of staff returned to work. CONCLUSION: The mobile/telemedicine health clinic is a novel innovation to increase access to acute care and reduce school absenteeism among both students and staff, potentially saving schools hundreds to thousands of dollars.

Comparison of Operative Experiences of PGY-1 and PGY-2 General Surgery Residents During Night-Float vs. 24-Hour Call Systems.

OBJECTIVE: We aimed to specifically compare the impact of a night-float system vs. a 24-hour call system on the number and types of cases performed by PGY-1 and PGY-2 general surgery residents to determine if both of these schedules could meet the ACGME first two-year 250 case minimum requirement, and if so, which schedule provided the best operative experience for PGY-1 and PGY-2 residents. DESIGN: This is a retrospective review of call schedules and operative case logs of PGY-1 and PGY-2 general surgery residents. Residents were separated into two groups based on type of call schedule: 24-hour vs. night-float. The case logs of PGY-1 and PGY-2 residents were obtained from the ACGME Case Log System and data analysis was performed between the two groups. SETTING: This study was performed at a general surgery residency at a hybrid academic center. PARTICIPANTS: Forty-three residents met inclusion criteria. Twenty-three were part of the night-float system and 20 were part of the 24-hour call system. RESULTS: Total cases and major cases for PGY-1 and PGY-2 years were compared between the two groups. The 24-hour call group had a significantly higher total number of cases than the night-float group (646.0 ± 181.5 vs. 504.8 ±148.9, p = 0.008). Major cases were also significantly higher in the 24-hour call group than the night-float group (418.5 ± 99.6 vs. 355 ± 99.5, p = 0.043). CONCLUSIONS: Both the 24-hour call and night-float systems were able to meet the ACGME first two year 250 case minimum requirement as well as follow work-hour guidelines. The 24-hour call system was associated with PGY-1 and PGY-2 residents having a better operative experience than the night-float system.

Optimal Predictor of Gonadal Viability in Testicular Torsion: Time to Treat Versus Duration of Symptoms.

BACKGROUND: We hypothesize that in testicular torsion, the duration of symptoms (DoS) better correlates with predicting testicular viability than minimizing the "time-to-treat" (TtT) after presentation to a medical facility. MATERIALS AND METHODS: Medical records of male pediatric patients treated for suspected diagnosis of testicular torsion in the emergency department (ED) from January 1, 2016, to December 31, 2018, were retrospectively evaluated. Forty-one patients met inclusion criteria. Statistical analysis compared testicular viability based on TtT, DoS, and site of initial presentation. RESULTS: Testicular salvage rates for patients presenting directly to our ED was 56.3% with an average TtT of 2.5 h versus 77.8% and 1.96 h, respectively, for transferred patients. Overall testicular survival was not statistically impacted by the difference in TtT. Comparing DoS, an 84% testicular salvage rate (DoS < 24 h) versus a 15.4% salvage rate (DoS > 24 h) was shown in patients presenting directly to our ED (P ≤ 0.0001). Within the total population (n = 41), a significant difference was also shown (P ≤ 0.0001) when comparing overall testicular salvage rates in patients presenting with <24 h versus >24 h total DoS (84% versus 25%). CONCLUSIONS: These data reveal that an alternative predictor of testicular salvage rates is a DoS < 24 h. This is a meaningful metric when providing accurate preoperating counseling to parents and may be a better focus of quality improvement efforts surrounding this topic.

Single-Incision Laparoscopic Appendectomy in Children And Conversion to Multiport Appendectomy.

BACKGROUND: Single-incision laparoscopic appendectomy (SILA) in the pediatric population has been well described. Our children's hospital has adopted this modality for nearly all appendectomies. From our center's experience, we hoped to identify factors that portend conversion from SILA to multiport appendectomy. We compared our cohort of conventional three-port laparoscopic appendectomy (CLA) for outcomes including operative time, postop length of stay (LOS), complications, and readmission. MATERIALS AND METHODS: A retrospective chart review of patients who underwent appendectomy from 2012 to 2017 at our children's hospital was performed. The type of appendectomy performed, if the case required conversion to multiple ports, and perforation status were recorded. Demographic data identified included age, sex, and body mass index. Outcomes analyzed were operative time, LOS, and postoperative complication/readmission rate. RESULTS: Of 1001 appendectomies performed, 959 (95.9%) were initiated with plan for SILA, and 35 (3.5%) were initiated CLA. Of those initiated SILA, 884/959 (92.2%) were completed without additional port placement. Cases which were not able to be completed SILA were statistically significantly more likely to be male patients, have increased body mass index, or perforated appendicitis. When compared to cases initiated CLA, SILA remained statistically similar for readmission and LOS but had significantly faster operative time. CONCLUSIONS: SILA appears to be a safe and efficient modality for the treatment of appendicitis in pediatric populations with no increased morbidity. Parents of children who are obese, males, or present with perforation should be counseled regarding the possibility of additional port placement or considered for initiating conventional three-port laparoscopic appendectomy.

Robotic inguinal lymph node dissection for melanoma: a novel approach to a complicated problem.

BACKGROUND: Indications for superficial inguinal lymph node (ILN) dissection in melanoma include fine needle aspiration or clinically positive ILN and sentinel lymph nodes (SLN). Open inguinal lymphadenectomy may be complicated by poor wound healing, deep vein thrombosis, and lymphedema. Technical considerations and case series of a novel surgical approach, robotic inguinal lymphadenectomy, are presented. METHODS: This is a case series of four robotic ILN dissections for melanoma at a tertiary care facility. Each patient had previously diagnosed melanoma by lymph node biopsy. Physician and patient jointly decided on robotic procedure after disclosure of this novel approach. Demographic, complication, pathological outcome, estimated blood loss (EBL), operative time, and length of stay (LOS) data were collected. RESULTS: No cases were aborted due to technical difficulty. The median patient age was 44.5 years (range 22-53 years) and median BMI was 27.5 (range 20.4-40.2). Operative time range was 120-231 min and EBL from 0 to 100 mL. Median nodal count was 5.5 (range 1-14 nodes). Patient LOS ranged from 0 (discharged from post anesthesia care unit) to 96 h. There was one complication of port site cellulitis, one seroma formation, and no instances of lymphedema. To date, there have been no deaths or melanoma recurrences in this population. CONCLUSION: Recent data suggest a minimum node count of six to seven for inguinal dissection. Of our four dissections, two were above this threshold and there were minimal postoperative complications. Given our limited sample size, future focus should be on increasing the data on this approach to optimize surgical outcomes and oncologic results.

Diagnostic performance of MDCT in identifying closed loop small bowel obstruction.

PURPOSE: To assess the diagnostic performance of MDCT in the diagnosis of closed loop small bowel obstruction. MATERIALS AND METHODS: One hundred fifty patients with CT reports including "small bowel obstruction (SBO)" between 1/30/2011 and 12/4/2012 were included (65 men, 85 women, mean age 63 years). CT examinations were independently and blindly reviewed by five radiologists to determine the presence of closed loop obstruction (CL-SBO) and to assess findings of bowel ischemia. Clinical records were reviewed to determine management and operative findings. Using operative findings as a gold standard, reader agreement for the diagnosis of and the CT findings associated with CLO was analyzed using Pearson's correlation (r). Positive predictive value (PPV) and negative predictive value for the diagnosis of CL-SBO and CT signs of bowel ischemia were analyzed. RESULTS: Eighty-eight of 150 patients underwent operative intervention for SBO and 24/88 were considered CL-SBO operatively. Average reader sensitivity and specificity for CL-SBO was 53 % (95 % CI 44-63 %) and 83 % (95 % CI 79-87 %). Reader agreement on CL-SBO was poor to moderate (K = 0.39-0.63). Reader agreement for CT signs of bowel ischemia resulting in a diagnosis of CL-SBO was weak (r = 0.19-0.32). CONCLUSION: The CT diagnosis of CL-SBO is complex and associated imaging findings have variable sensitivity for predicting a closed loop operative diagnosis. CT can be helpful in excluding a closed loop component in patients with SBO.

Comparative effectiveness of treatment strategies for severe splenic trauma in the pediatric population.

BACKGROUND: Splenic angioembolization (SAE) is increasingly used in the management of splenic injuries in adults, although its value in pediatric trauma is unclear. We sought to assess outcomes related to splenectomy vs SAE. METHODS: The National Trauma Data Bank was queried for patients 0 to 15 years of age from 2007 to 2011. Subgroup analysis of splenectomy vs SAE was performed for high-grade injuries using propensity analysis and inverse probability weighting. RESULTS: Of 11,694 children presenting with splenic trauma, over 90% were treated nonoperatively. Adjusted analysis of high-grade injuries included 265 children who underwent splenectomy and 199 who underwent SAE. The Injury Severity Score, number of transfusions, and complications rates were not significantly different between the 2 groups. Overall adjusted mortality for children with high-grade injuries was 13.4% following splenectomy and 10.0% following SAE (P = .31) CONCLUSION: Patients undergoing SAE for high-grade splenic trauma have comparable morbidity and mortality with splenectomy.

Image-guided percutaneous drainage vs. surgical repair of gastrointestinal anastomotic leaks: is there a difference in hospital course or hospitalization cost?

PURPOSE: To identify differences in hospital course and hospitalization cost when comparing image-guided percutaneous drainage with surgical repair for gastrointestinal anastomotic leaks. MATERIALS AND METHODS: A retrospective IRB-approved search using key words "leak" and/or "anastomotic" was performed on all adult CT reports from 2002 to 2011. CT examinations were reviewed for evidence of a postoperative gastrointestinal leak and assigned a confidence score of 1-5 (1 = no leak, 5 = definite leak). Patients with an average confidence score <4 were excluded. Type of surgery, patient data, method of leak management, number of hospital admissions, length of hospital stay, discharge disposition, number of CT examinations, number of drains, and hospitalization costs were collected. RESULTS: One hundred thirty-nine patients had radiographic evidence of a gastrointestinal anastomotic leak (esophageal, gastric, small bowel or colonic). Nine patients were excluded due to low confidence scores. Twenty-seven patients underwent surgical repair (Group A) and 103 were managed entirely with percutaneous image-guided drainage (Group B). There was no significant difference in patient demographics or number of hospital admissions. Patients in Group A had longer median hospital stays compared to Group B (48 vs. 32 days, p = 0.007). The median total hospitalization cost for Group A was more than twice that for Group B ($99,995 vs. $47,838, p = 0.001). Differences in hospital disposition, number of CT examinations, number of drains, and time between original surgery and first CT examination were statistically significant. CONCLUSION: Gastrointestinal anastomotic leaks managed by percutaneous drainage are associated with lower hospital cost and shorter hospital stays compared with surgical management.

Insurance status predicts acuity of thoracic aortic operations.

OBJECTIVE: Nonelective case status is the strongest predictor of mortality for thoracic aortic operations. We hypothesized that underinsured patients were more likely to require nonelective thoracic aortic surgery because of reduced access to preventative cardiovascular care and elective surgical services. METHODS: Between June 2005 and August 2011, 826 patients were admitted to a single aortic referral center and underwent 1 or more thoracic aortic operations. Patients with private insurance or Medicare (insured group, n=736; 89%) were compared with those with Medicaid or no insurance (underinsured group, n=90; 11%). RESULTS: The proportion of patients requiring nonelective surgery was higher for underinsured than insured patients (56% vs 26%, P<.0001). Multivariable analysis revealed underinsurance to be the strongest independent predictor of nonelective case status (odds ratio [OR], 2.67; P<.0001). Preoperative use of lipid-lowering medications (OR, 0.63; P<.009) or a history of aortic surgery (OR, 0.48; P<.001) was associated with a decreased risk of nonelective operation. However, after adjustment for differences in preoperative characteristics and case status, underinsurance did not confer an increased risk of procedural morbidity or mortality (adjusted OR, 0.94; P=.83) or late death (adjusted hazard ratio, 0.83, P=.58) when compared with insured patients. CONCLUSIONS: Underinsured patients were at the greatest risk of requiring nonelective thoracic aortic operation, possibly because of decreased use of lipid-lowering therapies and aortic surveillance. These data imply that greater access to preventative cardiovascular care may reduce the need for nonelective thoracic aortic surgery and lead to improved survival from thoracic aortic disease.

Gastroesophageal heterotopia and HER2/neu overexpression in an adenocarcinoma arising from a small bowel duplication.

Small bowel duplications are congenital structures commonly lined by heterotopic gastric or pancreatic mucosa. Though benign in children, small bowel duplications have the potential for malignant degeneration in adulthood. Here, we present the first reported case of metastatic adenocarcinoma arising from a small bowel duplication lined by gastroesophageal mucosa. The cancer demonstrated overexpression of the HER2/neu oncoprotein and amplification of the HER2/neu gene. This represents the only report of HER2 overexpression in this type of lesion. The patient is being treated with traditional chemotherapeutic agents in addition to monoclonal antibody therapy directed at the HER2 protein, and has demonstrated a clinical benefit from treatment. This case demonstrates that the anatomic location of a mass may be distinct from its biological origin, and this difference may have important practical implications for diagnostic testing and treatment.

Predictors of electrocerebral inactivity with deep hypothermia.

OBJECTIVE: Cooling to electrocerebral inactivity (ECI) by electroencephalography (EEG) remains the gold standard to maximize cerebral and systemic organ protection during deep hypothermic circulatory arrest (DHCA). We sought to determine predictors of ECI to help guide cooling protocols when EEG monitoring is unavailable. METHODS: Between July 2005 and July 2011, 396 patients underwent thoracic aortic operation with DHCA; EEG monitoring was used in 325 (82%) of these patients to guide the cooling strategy, and constituted the study cohort. Electroencephalographic monitoring was used for all elective cases and, when available, for nonelective cases. Multivariable linear regression was used to assess predictors of the nasopharyngeal temperature and cooling time required to achieve ECI. RESULTS: Cooling to a nasopharyngeal temperature of 12.7°C or for a duration of 97 minutes was required to achieve ECI in >95% of patients. Only 7% and 11% of patients achieved ECI by 18°C or 50 minutes of cooling, respectively. No independent predictors of nasopharyngeal temperature at ECI were identified. Independent predictors of cooling time included body surface area (18 minutes/m(2)), white race (7 minutes), and starting nasopharyngeal temperature (3 minutes/°C). Low complication rates were observed (ischemic stroke, 1.5%; permanent paraparesis/paraplegia, 1.5%; new-onset dialysis, 2.2%; and 30-day/in-hospital mortality, 4.3%). CONCLUSIONS: Cooling to a nasopharyngeal temperature of 12.7°C or for a duration of 97 minutes achieved ECI in >95% of patients in our study population. However, patient-specific factors were poorly predictive of the temperature or cooling time required to achieve ECI, necessitating EEG monitoring for precise ECI detection.

Self-reported barriers to pediatric surgical care in Guatemala.

Access to pediatric surgical care is limited in low- and middle-income countries. Barriers must be identified before improvements can be made. This pilot study aimed to identify self-reported barriers to pediatric surgical care in Guatemala. We surveyed 78 families of Guatemalan children with surgical conditions who were seen at a pediatric surgical clinic in Guatemala City. Spanish translators were used to complete questionnaires regarding perceived barriers to surgical care. Surgical conditions included hernias, rectal prolapse, anorectal malformations, congenital heart defects, cryptorchidism, soft tissue masses, and vestibulourethral reflux. Average patient age was 8.2 years (range, 1 month to 17 years) with male predominance (62%). Families reported an average symptom duration of 3.7 years before clinic evaluation. Families traveled a variety of distances to obtain surgical care: 36 per cent were local (less than 10 km), 17 per cent traveled 10 to 50 km, and 47 per cent traveled greater than 50 km. Other barriers to surgery included financial (58.9%), excessive wait time in the national healthcare system (10. 2%), distrust of local surgeons (37.2%), and geographic inaccessibility to surgical care (10.2%). The majority of study patients required outpatient procedures, which could improve their quality of life. Many barriers to pediatric surgical care exist in Guatemala. Interventions to remove these obstacles may enhance access to surgery and benefit children in low- and middle-income countries.

Risk factors for 1-year mortality after thoracic endovascular aortic repair.

OBJECTIVE: Thoracic endovascular aortic repair, although physiologically well tolerated, may fail to confer significant survival benefit in some high-risk patients. In an effort to identify patients most likely to benefit from intervention, the present study sought to determine the risk factors for 1-year mortality after thoracic endovascular aortic repair. METHODS: A retrospective review was performed on prospectively collected data from all patients undergoing thoracic endovascular aortic repair from 2002 to 2010 at a single institution. Univariate analysis and multivariate Cox proportional hazards regression analysis were used to identify risk factors associated with mortality within 1 year after thoracic endovascular aortic repair. RESULTS: During the study period, 282 patients underwent at least 1 thoracic endovascular aortic repair; index procedures included descending aortic repair (n = 189), hybrid arch repair (n = 55), and hybrid thoracoabdominal repair (n = 38). The 30-day/in-hospital mortality was 7.4% (n = 21) and the overall 1-year mortality was 19% (n = 54). Cardiopulmonary pathologies were the most common cause of nonperioperative 1-year mortality (22%, n = 12). Multivariate modeling demonstrated 3 variables independently associated with 1-year mortality: age older than 75 years (hazard ratio, 2.26; P = .005), aortic diameter greater than 6.5 cm (hazard ratio, 2.20; P = .007), and American Society of Anesthesiologists class 4 (hazard ratio, 1.85; P = .049). A baseline creatinine greater than 1.5 mg/dL (hazard ratio, 1.79; P = .05) and congestive heart failure (hazard ratio, 1.87; P = .08) were also retained in the final model. These 5 variables explained a large proportion of the risk of 1-year mortality (C statistic = 0.74). CONCLUSIONS: Age older than 75 years, aortic diameter greater than 6.5 cm, and American Society of Anesthesiologists class 4 are independently associated with 1-year mortality after thoracic endovascular aortic repair. These clinical characteristics may help risk-stratify patients undergoing thoracic endovascular aortic repair and identify those unlikely to derive a long-term survival benefit from the procedure.
