Increased pediatric sub-specialization is associated with decreased surgical complication rates for inpatient pediatric urology procedures

10 Year Analysis of Pediatric Surgery Fellowship Match and Operative Experience: Concerning Trends?

OBJECTIVE

This paper aims to evaluate the pediatric surgery training pipeline vis-à-vis the pediatric surgery match and operative experience of pediatric surgery fellows.

SUMMARY OF BACKGROUND DATA

Pediatric surgery remains a competitive surgical subspecialty. However, there is concern that operative experience for pediatric surgery fellows is changing. This paper examines the selectivity of the pediatric surgery match, along with the operative experience of pediatric surgery fellows to characterize the state of pediatric surgery training.

METHODS

The pediatric surgery fellowship match was analyzed from the National Resident Matching Program data from 2010 to 2019. Selectivity among fellowships was compared using analysis of variance with Dunnett test. Operative log data for pediatric fellows was analyzed using the Accreditation Council for Graduate Medical Education case logs from 2009 to 2019. Linear regression analysis was used to evaluate trends in operative volume over time.

RESULTS

Pediatric surgery had the highest proportion of unmatched applicants (47.2% ± 5.3%) and lowest proportion of unfilled positions (1.4% ± 1.6%) when compared to other National Resident Matching Program surgical fellowships. Accreditation Council for Graduate Medical Education case log analysis revealed a statistically significant decrease in cases for graduating fellows (-5.3 cases/year, P < 0.05). Total index cases decreased (-4.7 cases/year, P < 0.01, R 2 = 0.83) such that graduates in 2019 completed 59 fewer index operations than graduates in 2009.

CONCLUSION

Although pediatric surgery fellowship remains highly selective there has been a decline in the operative experience for graduating fellows. This highlights the need for evaluation of training paradigms and operative exposure in pediatric surgery to ensure the training of competent pediatric surgeons.

Case Volume Benchmarks During Residency and Fellowship Training for Pediatric Orthopedic Surgeons

Higher case volumes correlate with improved clinical outcomes across surgical specialties. This study establishes case volume benchmarks after completion of pediatric orthopedic fellowship training. Case logs for orthopedic surgery residents and pediatric orthopedic fellows at accredited programs were analyzed (2017-2018 to 2020-2021). Case volumes for pediatric orthopedic surgery were compared using parametric tests. Case logs from 3,000 orthopedic surgery residents and 149 pediatric orthopedic fellows were analyzed. There was an increase in total pediatric cases among orthopedic surgery residents over the study period (273 ± 68 to 285 ± 76, 1.1% annual increase, P<0.001). On average, pediatric orthopedic fellows reported 276 cases: Spine deformity (55 cases, 20%), foot and ankle deformity (45 cases, 16%), hip reconstruction (34 cases, 12%), limb deformity (32 cases, 12%), trauma lower limb (24 cases, 9%), treatment of supracondylar humerus fracture (23 cases, 8%), trauma upper limb (19 cases, 7%), clubfoot (18 cases, 7%), soft tissue procedures (13 cases, 5%), open treatment of femoral shaft fractures (6 cases, 2%), and treatment of infection (7 cases, 3%). Pediatric orthopedic fellows effectively doubled their pediatric case volume from fellowship training. The distribution of pediatric orthopedic fellow case volume percentiles was: 10th - 191 cases; 30th - 237 cases; 50th - 275 cases; 70th - 318 cases; 90th - 382 cases. Case volume benchmarks can help inform orthopedic trainees, faculty, and patients about the impact of pediatric orthopedic fellowship training. More research is needed to elucidate optimal training environments for future pediatric orthopedic surgeons.

Surgeon perceptions of volume threshold and essential practices for pediatric thyroidectomy✰

INTRODUCTION

The topics of sub-specialization and regionalization of care have garnered increased attention among pediatric surgeons. Thyroid surgeries are one such sub-specialty and are commonly concentrated within practices. A national survey was conducted examining current surgeon practices and beliefs surrounding pediatric thyroid surgery.

METHODS

Non-resident members of the American Pediatric Surgical Association (APSA) were surveyed in October 2020. Respondents were stratified based on self-reported thyroid surgical experience. Those who performed thyroid surgery were asked about surgical technique and operative practices; those who did not were asked about referral patterns. All respondents were asked about perceptions surrounding the volume-outcome relationship for pediatric thyroid surgery.

RESULTS

Among 1015 APSA members, 405 (40%) responded, with 79% (317/400) practicing at academic hospitals, 58% (232/401) practicing in major metropolitan area, and 41% (161/392) with over 10 years of attending pediatric surgery experience. Most respondents (88%, n = 356) agreed that thyroid surgery volume affects outcome, though wide variation was reported in the annual case threshold for "high volume" surgery. Eighty-four respondents (21%) reported performing ≥ 1 pediatric thyroid surgery in the past year. Of these, 82% routinely use recurrent laryngeal nerve monitoring, 32% routinely send hemithyroidectomy patients home the same day, and there was little consensus surrounding postoperative hypocalcemia management. The majority of respondents endorse performing thyroid procedures with a colleague.

CONCLUSIONS

Pediatric thyroid surgery appears to be performed by a subset of active pediatric surgeons, most of whom endorse the use of a dual operating team. More evidence is needed to build consensus around additional perioperative practices.

Impact of the Number of Board-Certified Pediatric Surgeons per Pediatric Population on the Outcomes of Laparoscopic Fundoplication for Neurologically Impaired Patients

Background and Aim: The distribution of board-certified pediatric surgeons (BCPSs) in Japan is highly biased. While Prefecture M has one of the smallest numbers of BCPSs per pediatric population, neighboring Prefecture K has one of the largest numbers of BCPSs per pediatric population. We examined the effect of BCPSs population on laparoscopic surgery and postoperative management and outcomes. Materials and Methods: We compared postoperative duration to full-dose enteral nutrition, postoperative hospital stay, and complications of neurologically impaired patients who underwent laparoscopic fundoplication in two prefectures from 2006 to 2019. Results: Laparoscopic fundoplication was performed in 17 patients in Prefecture M and 63 in K. The mean operative time was 248.8 ± 79.9 minutes in Prefecture M and 260.8 ± 94.8 in K (P = .64). The median number of days to full-dose enteral nutrition was 11.5 in Prefecture M and 10 in K (P = .29). The median postoperative hospital stay was 14 days in Prefecture M and 15 days in K (P = .38). Postoperative complications occurred in 7 cases in Prefecture M and in 10 in K. The incidence was significantly higher in Prefecture M than in K (P = .041). Conclusion: Areas with insufficient numbers of BCPSs have a higher risk of complications in laparoscopic surgery than areas with sufficient numbers.

Breast surgery super-specialization: Impact on advanced surgical training and research

The earliest records of breast cancer (BC) date back to 3,000 - 2,500 B.C., ever since multiple curative options have been explored. First known wide margin excision was performed around 1^st Century AD and a prototype of the modern-day BC surgery, Halsted radical mastectomy, was performed in the 20^th Century. BC is the most common cancer in Pakistan accounting for up to 14.5% of the total cancer incidences. Accredited breast surgery fellowships were established in the UK and USA in 2002 and 2003, respectively. In Pakistan, the movement was delayed and the two-year College of Physicians and Surgeons Pakistan (CPSP) accredited breast surgery fellowship program started in 2019. The increasing annual incidence and changes in demands have led to an increased percentage of General Surgery graduates taking up specialty training. PubMed search from 1990 to 2021 showed a rising trend in the number of breast cancer publications from Pakistan; from almost no papers before 1990 to 615 between 2012 to 2021. This remarkable surge in BC-related research can be explained by the commencement of fellowship programs in breast surgery and related fields. An increase in specialist training will yield better results in the management of patients, improve clinical trials and help produce more meaningful publications from the country.

Open versus minimally-invasive surgical techniques in pediatric renal tumors: A population-level analysis of in-hospital outcomes

INTRODUCTION

Minimally-invasive surgery (MIS) has been adopted slowly in pediatric oncology. We attempted to describe contemporary national trends in MIS use; we hypothesized that adolescents (who are more likely to have relatively small renal cell carcinomas) would have a higher proportion of MIS than younger children (who are more likely to have relatively large Wilms tumors) and that this relationship would vary by region.

OBJECTIVE

To explore whether pediatric urologic oncology outcomes vary by patient age or by surgical technique.

METHODS

We queried the 1998-2014 National Inpatient Sample (NIS) and included encounters in children aged ≤ 18 y, ICD-9 diagnostic code for renal tumor, and procedure code for open or MIS partial or radical nephrectomy. All analyses used weighted descriptive statistics and outcomes are compared based on age group (</>10 y) or surgery type; Wald-Chi square test was used for differences in proportions and unadjusted weighted ANOVA was used to test for differences in means.

RESULTS

9259 weighted encounters were included; 91% were <10 years old and 50.7% were female. MIS surgery accounted for 1.8% of encounters; there was a difference in proportions by age group (1% <9 y vs. 9.9% >9 y, p < 0.01). The proportion of surgery type was similar across regions within age groups, however. Complications occurred in 13.3% of encounters; mean inpatient length of stay was 8.9 days (SD: 0.3); mean cost was $ 34,457.68 (SD: $1197.00). There was no evidence of a difference between surgery type and proportion of post-operative complications, mean inpatient length of stay or mean inpatient cost.

DISCUSSION

The admission-based, retrospective design of NIS left us unable to assess long-term outcomes, repeated admissions, or to track a particular patient across time; this is particularly relevant for oncologic variables on interest such as tumor stage or event-free survival. We were similarly limited in evaluating the effect of pre-surgical referral patterns on patient distributions.

CONCLUSION

In this preliminary descriptive analysis, MIS techniques were infrequently used in children, but there was a higher proportion of MIS use among adolescents. There were similar proportions of surgery type across geographic regions within the United States. Whether this infrequent usage is appropriate is as yet unclear given the lack of Level I evidence regarding the relative merits of MIS and open surgery for pediatric and adolescent renal tumors.

Comparative Analysis of Total Knee Arthroplasty Outcomes Between Arthroplasty and Nonarthroplasty Fellowship Trained Surgeons

Background

An adult reconstruction (AR) fellowship is designed to provide advanced training for a broad range of primary reconstructive and complex knee revision surgeries. This study aims to identify outcome differences between primary total knee arthroplasty (TKA) performed by AR fellowship-trained surgeons and non-AR (NAR) fellowship-trained surgeons.

Material and Methods

We retrospectively reviewed 7415 patients who underwent primary TKA from 2016 to 2020. Two cohorts were established based on whether the operation was performed by an AR or NAR fellowship-trained surgeon. Demographic, clinical data, and patient-reported outcome measures were collected at various time-points (preoperatively, 3 months, 1 year). Demographic differences were assessed with chi-square and independent sample t-tests. Primary outcomes were compared using multilinear regressions, controlling for demographic differences.

Results

AR surgeons performed 5194 (70%) cases while NAR surgeons performed 2221 (30%) cases. Surgical time (minutes) significantly differed between the 2 groups (101.26 vs 111.56; P < .001). Length of stay, 90-day all-cause readmissions, revisions, and all-cause emergency department visits did not statistically differ (P = .079, P = .978, P = .094, and P = .241, respectively). AR surgeons were more likely to discharge their patients home than NAR surgeons (P = .001). NAR group reported lower KOOS, JR scores at 3 months and 1 year (preop: 45.30 vs 45.79, P = .728; 3 months: 64.73 vs 59.47, P < .001; 1 year: 71.66 vs 69.56, P = .234); however, only 3-month scores statistically differed. Veterans RAND-12 Physical and Mental components scores (VR-12 PCS and MCS) were not statistically significant at any time-point between the cohorts. Delta-improvements preoperatively to 1 year in KOOS, JR (26.36 vs 23.77; P < .001) and VR-12 PCS (11.98 vs 10.62; P < .001) scores were significantly higher for the AR cohort but did not exceed the minimal clinically important difference.

Conclusion

This study demonstrates significantly shorter surgical times and greater improvements in KOOS, JR and VR-12 PCS scores associated with TKAs performed by AR fellowship-trained surgeons.

Specialised training in paediatric anaesthesia: Need of the hour

Paediatric anaesthesia is an upcoming speciality which is gaining wide interest and can be a career choice for the new trainees. The need to develop paediatric anaesthesia as a speciality was realised with the progress in the field of paediatric surgery. The profile of the 'patient' encountered by a paediatric anaesthesiologist spans from an extremely premature neonate on the fringes of survival, to a full-grown adolescent equivalent to an adult. Perioperative morbidity and mortality are 2-3 times higher in infants and neonates compared to adults particularly in middle and low-income countries. The anatomical, physiological, pharmacological variations and presence of congenital cardiac, pulmonary and metabolic diseases in young children make perioperative management challenging. Special expertise and training are required for anaesthetic management of these preverbal children. In India, 3-years DM and 1-year Fellowship courses in paediatric anaesthesia are now available for specialisation. An ideal paediatric anaesthesia training centre should have substantial paediatric and neonatal patient load with exclusive intensive care facility. Paediatric anaesthesiologists, having knowledge of several facets of paediatrics and anaesthesia are capable of coordinating with health care professionals performing procedures outside the operating room. Paediatric anaesthesia, as a career thus offers a great opportunity to enhance quality and safety of anaesthesia in this high-risk surgical population. Persistent coordinated team efforts improve patient outcomes, reduce stress at work and increase job satisfaction.

Subspecialization in pediatric surgery: Results of a survey to the American Pediatric Surgical Association

BACKGROUND

Current practice patterns and opinions regarding subspecialization within pediatric surgery are not well known. We aimed to characterize the prevalence of and attitudes surrounding subspecialization within pediatric surgery.

METHODS

An anonymous survey regarding subspecialization was distributed to all nonresident members of the American Pediatric Surgical Association.

RESULTS

Of 1118 surveys, we received 458 responses (41%). A majority of respondents labeled themselves 'general pediatric surgeons' (63%), while 34% considered themselves general surgeons with a specific clinical focus, and 3% reported practicing solely within a specific niche. Subspecialists commonly serve as consultants for relevant cases (52%). Common niches included oncology (10%) and anorectal malformations (9%). Subspecialists felt to be necessary included transplant (79%) and fetal (78%) surgeons. Opinions about subspecialization were variable: 41% felt subspecialization improves patient care while 39% believe it is detrimental to surgeon well-roundedness. Only 10% felt subspecialists should practice solely within their subspecialty. Practicing at an academic hospital or fellowship program correlated with subspecialization, while length of time in practice did not.

CONCLUSION

While pediatric surgeons report that subspecialization may benefit patient care, concerns exist regarding the unfavorable effect it may have on the individual surgeon. A better understanding of how subspecialization affects quality and outcomes would help clarify its utility.

Can the Use of Video-Based Interventions Increase Public Knowledge About Endocrine Surgeons?

BACKGROUND

Endocrine surgery (ES) is a relatively young subspecialty of general surgery, and prior research has shown low public awareness of these specialists' roles. We hypothesized that a video-based intervention could increase public knowledge of the specialty in an effective and efficient manner.

METHODS

Participants were recruited at three public locations (a farmer's market, a public park, and a university hospital) and were given a three-question survey to assess baseline knowledge of ES. They then watched one of two video-based educational interventions and completed an identical postintervention survey. Two surveyors recruited 80 individuals per site, with 40 participants in each intervention group. Participants' sex and age and whether or not they were on clinical staff at the University of Alabama at Birmingham were recorded.

RESULTS

A total of 240 participants were recruited; 61.3% female with median age 40 y. Preintervention, only 42.1% of participants could correctly define ES. ES were confused with endocrinologists by 44.6%, which was not different between sites (P = 0.09). Significantly, more participants at all sites could correctly define ES postintervention (67.9% versus 42.1%; P < 0.001). Clinical staff did not perform better than the lay public at any location (P = 0.32). The long video had a significantly greater increase in correct responses compared with the short video overall (32.5% versus 19.1%; P < 0.001) and at each location.

CONCLUSIONS

This study confirms the public's general lack of knowledge about ES and their scope of practice. A video-based intervention was successful in improving knowledge of the practice of ES, with a longer, explanatory video being most effective.

Total Hip Arthroplasty for Femoral Neck Fracture: The Economic Implications of Orthopedic Subspecialty Training

BACKGROUND

Hip fractures have significant economic implications as a result of their associated direct and indirect medical costs. Under alternative payment models, it has become increasingly important for institutions to find avenues by which costs could be reduced while maintaining outcomes in these cases.

METHODS

A multi-institutional retrospective analysis of Medicare patients who underwent total hip arthroplasty (THA) for femoral neck fracture was conducted to assess the impact of fellowship training in adult reconstruction (AR) on the total costs of the 90-day episode of care. Patients were divided into 2 cohorts according to fellowship training status of the operating surgeon: (1) AR-trained and (2) other fellowship training (non-AR). The primary outcome was the total cost of the 90-day episode of care converted to a percentage of the bundled payment target price.

RESULTS

A total of 291 patients who underwent THA for the treatment of a femoral neck fracture were included. The average total cost percentage of the 90-day episode of care was significantly lower for the AR cohort 70.9% (±36.6%) than the non-AR cohort 82.6% (±36.1%) (P < .01). After controlling for baseline demographics in the multivariable logistic regression, the care episodes in which the operating surgeons were AR fellowship-trained were still found to be significantly lower, at a rate of 0.87 times the costs of the non-AR surgeons (95% confidence interval 0.78-0.97, P = .011). In addition, the non-AR cohort exceeded the bundle target price more frequently than the AR cohort, 49 (28.7%) vs 16 (13.3%) (P = .02).

CONCLUSION

In an era of bundled payments, ascertaining factors that may increase the value of care while decreasing the cost is paramount for institutions and policymakers alike. The results presented in this study suggest that in the femoral neck fracture population, surgeons trained in AR achieve lower total costs for the THA episode of care. Furthermore, non-AR fellowship-trained surgeons exceeded the bundled payment target more frequently than the AR surgeons.

Challenges of training and delivery of pediatric surgical services in developing economies: a perspective from Pakistan

BACKGROUND

As the pediatric population requiring health services rises globally, developing countries are struggling to cater to the growing burden of non-communicable diseases - particularly those requiring specialized surgical care.

MAIN BODY

Despite the literature supporting specialized pediatric surgical care, the developing world is far from meeting the American Pediatric Surgical Association (APSA) Manpower taskforce recommendation of at least 1 qualified pediatric surgeon per 100,000 patients (0-15 years-old). In Pakistan, there is an unmet surgical need in the pediatric population due to a multitude of short shortcomings, notably in quality and quantity of the training programs on offer, and urgent short- and long-term steps are needed to improve this dire situation.

CONCLUSION

It is crucial for the global surgical community to take steps, especially with regards to pediatric surgical training, to ensure delivery of accessible and quality surgical care to the world's children.

Are we ready for urological subspecialty-based practice in India? The resident's perspective

Introduction:

In the current era, every broad specialty has diversified into many subspecialties including urology, which is one of the most dynamic fields. The concept of early sub-specialization relies on excelling in a niche area of interest. While this concept is appealing to the most, no formal evaluation of our residency programs has ever been conducted with regard to their adequacy in terms of equipping residents to make informed sub-specialization choices. We performed a survey amongst urological residents, in an attempt to gather information on some unanswered questions related to our residency training programs and the concept of sub-specialization.

Methods:

Using the Delphi principles, we conducted a survey consisting of 46 questions, amongst the Indian Urological residents (n = 85), to assess the overall exposure to various subspecialties during their residency program, and the inclination of residents towards them.

Results:

Residents get a fair exposure to endourology, uro-oncology, female urology and reconstructive urology during their residency. However, the same did not hold true for pediatric urology, andrology and laparoscopic/robotic surgery. 90% of the residents expressed an inclination towards academic practice, while 76.5% were interested in sub-specialization. 60% of the residents felt that they had obtained adequate exposure during residency to make a decision in this regard. Less than 20% were inclined towards female urology, andrology or pediatric urology as a career option.

Conclusion:

There is a growing interest and inclination amongst Indian Urological residents to attain expertise in sub-specialised fields. However, our current residency programs need consolidated efforts to ensure an adequate exposure to all the aspects of Urology, especially in the subspecialties of pediatric urology, andrology and minimally invasive urology. Training should be optimized to a level, which enables the residents to take a well informed decision regarding their choice of subspecialised career path.

Relative to open surgery, minimally-invasive renal and ureteral pediatric surgery offers no improvement in 30-day complications, yet requires longer operative time: Data from the National Surgical Quality Improvement Program Pediatrics

Purpose

Performance of minimally-invasive surgery (MIS) is increasing relative to open surgery. We sought to compare the contemporary rates of short-term complications of open versus laparoscopic renal and ureteral surgery in pediatric patients.

Materials and Methods

A retrospective cross-sectional analysis of the National Surgical Quality Improvement Program Pediatrics database was performed of all cases in 2014 identified using CPT procedure codes for nephrectomy, partial nephrectomy (PN), ureteroneocystostomy (UNC), and pyeloplasty, and reviewed for postoperative complications. Univariate analysis was performed to determine 30-day complications, with comparison between open and MIS approaches. Receiver operator curve (ROC) analysis was performed to determine differences in body surface area (BSA) and age for open versus MIS.

Results

Review identified 207 nephrectomies, 72 PN, 920 UNC, and 625 pyeloplasties. MIS was associated with older age and larger BSA except for cases of UNC. Apart from PN, operative durations were longer with MIS. However, only PN was associated with significantly longer length of hospital stay (LOS). There was no difference in incidence of all other 30-day complications. When evaluating BSA via ROC, the area under the curve (AUC) was found to be 0.730 and was significant. Children with a BSA greater than 0.408 m² were more likely to have MIS (sensitivity, 66.9%; specificity, 69.3%). Regarding age, the AUC was 0.732. Children older than 637.5 days were more likely to have MIS (sensitivity, 72.8%; specificity, 63.3%).

Conclusions

Pediatric MIS is associated with longer operative time for nephrectomy, but shorter LOS following PN. Surgical approach was not associated with difference in short-term complications.

Open versus minimally invasive surgical approaches in pediatric urology: Trends in utilization and complications

OBJECTIVE

Minimally invasive surgery (MIS) techniques are anecdotally reported to be increasingly used, but little objective data supports this. Our objective was to assess trends in MIS utilization across various procedures in pediatric urology and to compare postoperative complication rates between MIS and open procedures.

METHODS

We analyzed the 1998-2012 Nationwide Inpatient Sample. We identified children (<18 years old) undergoing open and MIS inpatient procedures and any in-hospital post-operative complications that occurred during that postoperative hospitalization. We utilized propensity score matching and multivariable logistic regression to adjust for confounding factors.

RESULTS

We identified 163,838 weighted encounters in the "overall cohort," 70,273 of which were at centers performing more than five MIS procedures over the years studied. Use of MIS techniques increased significantly over time for several procedures, most prominently for nephrectomy (Fig.). The overall rate of complications was lower in patients undergoing MIS compared with open surgery (6% vs. 11%, p < 0.001). Specialized centers had a significantly lower overall rate of complications than unspecialized centers (9% vs. 12%, p < 0.001). Within specialized centers, MIS had lower complication rates than open procedures (7% vs. 9%, p < 0.001); this finding was consistent even after adjusting for other factors (OR 0.71, p = 0.02).

DISCUSSION

Limitations include that these data may not be generalizable to encounters not in the sample pool. As a large, retrospective, administrative database, NIS may be affected by miscoding bias - rendering our analysis sensitive to the accuracy of procedure coding in NIS. Although the accuracy level of NIS is high for an administrative database, it is possible at least some portion of our cohort may be incorrectly coded. Further, the NSQIP complications we identified may represent associated comorbidities and not true postoperative complications, as NIS does not provide temporal relationships between different diagnosis codes. Despite these limitations, we note that the NIS database is rigorously monitored and audited for coding accuracy and, therefore, represents a reasonably reliable panorama of the characteristics of an inpatient surgical cohort. However, it is important to note that the choice of operative modality is, undoubtedly, multifactorial and patient/setting-specific.

CONCLUSIONS

There is increasing use of MIS for pediatric urology procedures, although utilization rates vary among procedures. MIS was associated with a lower postoperative complication rate than for open procedures. Higher-volume MIS centers have a lower complication rate than lower-volume centers.
