Variability in pediatric appendectomy: The association between disposable supply cost and procedure duration.

BACKGROUND: Pediatric appendicitis accounts for a notable proportion of health care use and cost in the United States. To identify opportunities for cost savings during pediatric laparoscopic appendectomy, this study assessed whether surgeons' use of costlier disposable supplies correlated with procedure duration and patient outcomes. METHODS: This retrospective cross-sectional study assessed laparoscopic appendectomy for uncomplicated pediatric appendicitis at 2 tertiary-care academic hospitals. The cost of disposable surgical supplies, procedure duration, and patient outcomes were obtained from medical records. The correlation between average supply cost and procedure duration among surgeons was assessed using Pearson's correlation coefficient. Associations between use of specific disposable supplies and supply cost or procedure duration were assessed using Student's t tests. RESULTS: A total of 380 laparoscopic appendectomies were performed by 11 surgeons. Mean normalized supply cost varied between surgeons (range: 60.6%-151.1%) and was not correlated with procedure duration (R = 0.2951, P = .378). The use of energy-based sealing devices (76.7% increase, P < .001), staplers (38.4% increase, P < .001), endoscopic specimen pouches (45.3% increase, P < .001), and disposable ports (43.6% increase, P < .001) increased overall disposable supply cost. None of the disposable supplies in this analysis were associated with shorter procedures. Based on Medicaid reimbursement, the interquartile range of supply cost was 9.2% and 6.0% of hospital revenue at each site. CONCLUSION: Surgeons varied in their use of disposable supplies for pediatric laparoscopic appendectomy, but the cost of supplies used did not influence outcomes. Incentivizing more judicious supply use may reduce costs related to pediatric appendicitis.

The Limited Utility of Routine Culture in Pediatric Pilonidal, Gluteal, and Perianal Abscesses.

BACKGROUND: Pilonidal, buttock, and perianal abscesses are common reasons for surgical consultation in the pediatric emergency department. Treatment typically includes a bedside incision and drainage, often followed by an abscess culture, and a course of oral antibiotics. We aimed to study the impact of culture data on changes in management and clinical outcomes. We hypothesized that management is unaffected by culture data, and therefore, fluid culture from pilonidal, buttock, and perianal abscesses in the pediatric population may represent an unnecessary laboratory test and cost. MATERIALS AND METHODS: A single institution's electronic medical record was searched between February 1, 2013 and August 1, 2017, identifying 249 pediatric patients meeting the inclusion criteria: age 0 to 18 y; diagnosis of pilonidal, buttock, or perianal abscess; bedside incision and drainage. Patients were divided into two different comparison groups for data analysis based on the presence or absence of culture and recurrence or no recurrence. RESULTS: Culture results directly altered management in only 5 patient encounters (2.7% of all cultured). When comparing groups by culture or no culture, no statistically significant difference in recurrence rate (P = 0.4) was noted. When comparing groups by recurrence versus no recurrence, we found no statistically significant difference between sex, resident type, vessel loop use, packing use, or antibiotic use (P > 0.05). CONCLUSIONS: We conclude that microbiological culture results are of limited utility in the management of pediatric pilonidal, buttock, and perianal abscesses as they do not appear to alter treatment, and omission of culture is not associated with failure of surgical management.

Surgical tray optimization as a simple means to decrease perioperative costs.

BACKGROUND: Health care spending in the US remains excessively high. Aside from complicated, large-scale efforts at health care cost reduction, there are still relatively simple ways in which individual hospitals can cut unnecessary costs from everyday operations. Inspired by recent publications, our group sought to decrease the costs associated with surgical instrument processing at a large, multihospital academic center. METHODS: This was a single-site observational study conducted at a large academic medical center. At the study start, all attending surgeons within the section of pediatric surgery agreed to standardize the pediatric surgery trays and to eliminate instruments that were deemed unnecessary from each tray. A multidisciplinary start-up meeting was held, and this meeting included stakeholders from central sterile processing, operating room nursing, scrub technicians, and materials management along with all five pediatric surgeons. Each tray was addressed individually. Instruments were eliminated from trays only if there was unanimous agreement among all the surgeons in the group. If no instruments in a given surgical tray were deemed necessary, the entire tray was eliminated from sterile processing rotation. Feedback questionnaires were drafted by the multidisciplinary team that participated in the start-up meeting. Surgeons were allowed to request for certain instruments to be placed back into the trays at any time, and the questionnaires also allowed for free-hand comments. Surgical kit preparation time was obtained from the institutional barcode scanning system. The cost per second of sterile processing labor was calculated using regional median salary for sterile processing technicians in the state of Connecticut. Using the pediatric surgery section as the model unit, this method was then applied to pediatric urology, neurosurgery, spine surgery, and orthopedics. RESULTS: The pediatric surgery section eliminated an average of 59.5% of instruments per tray, resulting in an overall reduction of 1826 (39.5%) instruments from rotation, 45,856 fewer instruments processed per year, and nine trays eliminated completely from regular rotation. Processing time for six commonly used trays was reduced by an average of 28.7%. The urology section eliminated 18 trays from regular rotation and 179 (10.1%) instruments in total. Pediatric orthopedics, neurosurgery, and spine sections eliminated 708 (17.1%), 560 (92.7%), and 31 (32.2%) instruments, respectively, resulting in approximately 18,804 fewer instruments processed per year. Among all five surgical sections, annual instrument cost avoidance after tray optimization was estimated at $53,193 to $531,929 using average instrument life spans ranging from 1-10 y. Negative feedback and requests for instrument replacement were both minimal on feedback questionnaires. CONCLUSIONS: Surgical tray optimization represents a relatively simple microsystem improvement that could result in significant hospital cost reduction. Although difficult to quantify, other gains from surgical kit optimization include decreased weight per tray, decreased materials cost, and decreased labor required to count, decontaminate, and pack surgical trays.

Accurate assessment of bowel length: the method of measurement matters.

PURPOSE: Small intestinal length has prognostic significance for patients with short bowel syndrome, and accurate measurement of Roux-en-Y limbs is considered important. The flexible elasticity of bowel makes its measurement highly subjective, yet a recommended method for intestinal measurement allowing accurate comparisons between surgeons remains undefined. Measurement of intestinal length has been described, but no comparison of the fidelity of measurement technique has been made. We hypothesized that silk suture and umbilical tape would yield the most consistent measurements. METHODS: This institutional review board-approved prospective trial enrolled 12 volunteer surgeons and two Institutional Animal Care and Use Committee-donated rabbits. Participants were asked to measure short, medium, and long segments of small intestine in a euthanized rabbit using common operating room tools: 18-in silk suture, 75-cm umbilical tape, 15-cm straight ruler, laparoscopic Dorsey bowel graspers. Data were analyzed by analysis of variance repeated measures model. RESULTS: Over short segments, intestinal measurements by grasper were significantly shorter than those by tape (P = 0.002) and ruler (P = 0.039). Over medium lengths of bowel, measurements by grasper were significantly shorter than those by suture (P = 0.032) and tape (P = 0.046), and measurements by ruler also were significantly shorter than those by suture (P = 0.008). Over the long intestinal segment, measurements by ruler resulted in the greatest variability, and comparison of variance across all possible pairs of groups found significant difference by method of measurement (P = 0.049). There was a significant difference in measurements taken along the mesenteric border compared with those taken along the antimesenteric border (P = 0.001). CONCLUSIONS: Measurement technique along short segments matters less; however, rigid tools underestimate length, and smaller variances in measurement by silk suture and umbilical tape suggest that these methods are more reliable across longer distances.
