Patient Experience with Telehealth Medicine During the Ongoing COVID-19 Pandemic in New York City.

Background: The COVID-19 pandemic accelerated integration of telehealth services into OBGYN practices in New York City. Since then, studies have shown high patient satisfaction with OBGYN telehealth services. However, few studies have compared satisfaction between obstetric and gynecologic patients. The primary objective of this study was to compare satisfaction with telehealth services between obstetric and gynecologic patients. Methods: This was an institutional review board-approved cross-sectional survey study among patients who had a telehealth visit at NYU OBGYN Faculty Group Practice from March 2020 to March 2021. Results: Gynecologic patients had higher rates of being "completely satisfied" compared with obstetric patients (40% vs. 24%, p < 0.001). Gynecologic patients were more likely to opt for telehealth services than obstetric patients both during a pandemic (70% vs. 59%, p < 0.001) and in the absence of a pandemic (53% vs. 37%, p < 0.001). Discussion: Prior studies have demonstrated high satisfaction with OBGYN telehealth. However, obstetric patients were less likely than gynecologic patients to feel satisfied with and opt for telehealth services.

Pediatric Femoral Shaft Fractures: A Multicenter Review of the AAOS Clinical Practice Guidelines Before and After 2009.

BACKGROUND: To determine if the AAOS clinical practice guidelines (CPG) for the treatment of pediatric femoral shaft fractures (2009) changed treatment, we analyzed pediatric femoral shaft fractures at 4 high-volume, geographically separated, level-1 pediatric trauma centers over a 10-year period (2004 to 2013). METHODS: Consecutive series of pediatric femoral shaft fractures (ages, birth to 18 y) treated at the 4 centers were reviewed. Treatment methods were analyzed by age and treatment method for each center and in aggregate. RESULTS: Of 2646 fractures, 1476 (55.8%) were treated nonoperatively and 1170 fractures operatively. Of the operative group, flexible intramedullary nails (IMN) were used for 568 patients (21.5%), locked intramedullary nails (LIMNs) for 309 (11.7%), and plating for 188 (7.1%). In total, 105 fractures were treated with external fixation or skeletal traction. Analysis before and after the CPG publication revealed a significant increase in the use of interlocked IMNs in patients younger than 11 years (0.5% before, 3.8% after; P<0.001). Over the same time period there was an increase in surgical management, regardless of technique, for patients younger than 5 years (6.4% before, 8.4% after; P=0.206). There were considerable differences in treatment among centers: 74% of fractures treated with plating were from a single center (center A), which also contributed 68% of patients younger than 5 years treated with plating; center B had the highest rate (41%) of flexible IMN in children younger than 5 years; center C had the highest rate (63%) of LIMN in children younger than 11 years; and center D treated the fewest patients outside the CPG guidelines. CONCLUSIONS: Following publication of the AAOS CPG, there was a significant increase in the use of LIMNs in patients younger than 11 years old and a trend toward surgical treatment in patients younger than 5 years. The considerable variability among centers in treatment methods and adherence to the CPG highlights the need for further outcome studies to better define optimal treatment methods and perhaps update the AAOS CPG guidelines. LEVEL OF EVIDENCE: Level III-therapeutic.

Triggered EMG (T-EMG) Values of Pedicle Screws with a Powered Screwdriver vs A Standard Probe in Adolescent Idiopathic Scoliosis Do Not Agree: A Prospective Validation Study.

Triggered electromyography (t-EMG) is a common technique used during spinal instrumentation in surgery for adolescent idiopathic scoliosis. This study tests the validity of t-EMG values obtained with a standard ball-tipped probe after completion of screw placement versus t-EMG values obtained during screw insertion with a powered screwdriver. t-EMG values were collected for screws spanning T7-L5 using both a standard probe and a powered screwdriver. A power analysis determined that a sample size of 300 screws would provide enough precision to estimate limits of agreement within ±2 mA. A monopolar constant current stimulation technique (0.2 ms duration and 3.11 Hz stimulation rate) was used at each level. EMG was acquired with placement of bipolar pairs of subdermal needle electrodes. A Bland-Altman plot was used to assess agreement between threshold readings from the two techniques. Twenty-nine patients were enrolled in this study with 305 screws. t-EMG values measured using a powered screwdriver were on average 1 mA lower than values from a standard probe. When readings less than or equal to 20 mA were considered, the limits of agreement were approximately 4 and 7 mA overall. In total, 28/305 (9%) screws were removed and reinserted, 9/305 (3%) screws were redirected, and 3/305 (1%) screws were aborted based on t-EMG readings. Despite a small overall difference in t-EMG value between the standard probe and screwdriver, there was still large variability in agreement between the two techniques. t-EMG values obtained with a powered screwdriver during screw insertion are not interchangeable with values measured by a probe.

Classification of Early Onset Scoliosis has Excellent Interobserver and Intraobserver Reliability.

BACKGROUND: Classification systems can be useful tools for clinical care and research but must be proven as reliable. The purpose of this study was to evaluate the interobserver and intraobserver reliability of the Classification of Early Onset Scoliosis (C-EOS) scheme. METHODS: After IRB approval, 50 cases were drawn from a prospectively collected database of patients with EOS. Cases were selected using a stratified randomization scheme based on etiology. These cases were used to create an internet survey that was sent to pediatric orthopaedic faculty, research coordinators, and fellows involved in EOS care and research. Participants were asked to classify each case and were provided with a written C-EOS scheme that could be referenced while they completed the survey. Surveys were sent to participants twice, 3 weeks apart, to assess both intraobserver and interobserver reliability. Fleiss κ and Cohen κ were used to assess interobserver and intraobserver reliability, respectively. RESULTS: There were 36 total participants, 29 who completed the survey twice (21 faculty, 13 research coordinators, and 2 fellows). Overall Fleiss κ coefficient for interobserver reliability was excellent across the major categories of etiology (0.84), major curve (0.93), and kyphosis (0.96). Overall intraobserver reliability was excellent with Cohen κ values for etiology (0.92), major curve (0.96), and kyphosis (0.98). Faculty members had excellent agreement for etiology (0.90), major curve (0.91), and kyphosis (0.96). Research coordinators had high levels of agreement for etiology (0.78), and excellent for major curve (0.95) and kyphosis (0.96). Intraobserver reliability was excellent across all major categories for all groups: faculty, research coordinators, and fellows. CONCLUSIONS: The study shows high levels of interobserver and intraobserver agreement of the C-EOS scheme. The C-EOS scheme can be used as a reliable tool for classifying EOS patients for clinical communication and research. LEVEL OF EVIDENCE: Level II-diagnostic study.

Variability of Surgical Site Infection With VEPTR at Eight Centers: A Retrospective Cohort Analysis.

STUDY DESIGN: Retrospective review. OBJECTIVES: To describe clinical characteristics and infection rates in modern vertical expandable prosthetic titanium rib (VEPTR) surgery. SUMMARY OF BACKGROUND DATA: Prior studies have demonstrated infection rates from 10% to 30% with VEPTR surgery. METHODS: A retrospective query was done on an institutional review board-approved, multicenter prospectively collected database for patients implanted with VEPTR from 2007 to 2013 at eight sites. This identified 213 patients with appropriate data for analysis. Average follow-up was 4.1 years (range 1.7-6.3). Data collected included a Classification of Early-Onset Scoliosis (C-EOS) diagnosis, American Society of Anesthesiologists Physical Status (ASA-PS), major Cobb angle, construct type, clinical symptoms, and microbiology. The distribution of infection rates across all the study sites was compared. The exact p value was estimated by Monte Carlo simulation. RESULTS: Overall, 18% (38/213) of patients implanted with VEPTR developed infection requiring operative debridement. There were significantly different infection rates among the sites, ranging from 2.9% to 42.9% (p = .029). The average time to infection was 70 days (range 8-236) after the infecting procedure. The majority of infections were due to gram-positive bacteria (80%, 44/55), the most prevalent being methicillin-sensitive Staphylococcus aureus (45%, 25/55). There were 20 patients (53%, 20/38) with either partial or complete implant removal to resolve infection; however, only 3 of 38 (8%) of these resulted in abandonment of VEPTR treatment. There was no difference in infection rate across the primary C-EOS diagnosis categories (p = .21) or based on ASA score (p = .53). After controlling for study site, the odds ratio of an infection following an implant procedure versus an expansion was 2.8 (p = .002). There was no difference in the odds ratio of an infection between the other procedure types (implant, expansion, exchange/revision). CONCLUSIONS: There were significant differences in infection rates between sites. The variability in infection rate indicates a need for guided efforts to standardize best practices for infection control in VEPTR surgery. LEVEL OF EVIDENCE: III, therapeutic study.

Routine radiographs at time of pin removal after closed reduction and percutaneous pinning for type 2 supracondylar humerus fractures do not change management: a retrospective cohort study.

PURPOSE: Radiographs are usually taken on day of pin removal for children treated with closed reduction and percutaneous pinning (CRPP) of type 2 supracondylar humerus fractures. The purpose of this study was to determine whether radiographs taken at time of pin removal for patients recovering uneventfully alter management. METHODS: After IRB approval, billing records identified 1213 patients aged 1-10 years who underwent elbow surgery between 2007 and 2013 at our institution for a supracondylar humerus fracture. Of these patients, 389 met inclusion criteria. Clinical charts were reviewed for demographics, operative details, and clinical follow-up, focusing on clinical symptoms present at pin removal. Radiographs taken at time of pin removal and subsequent visits were assessed for healing and fracture alignment. RESULTS: In no case was pin removal delayed based on radiographs. One hundred and nineteen (31 %) patients had radiographs taken following pin removal; in no case was loss of reduction found among these patients. No cases of neurologic or vascular injury, re-fracture, or loss of reduction occurred. Infection occurred in 12 patients (3 %). Pins were kept in place for 23.8 ± 4.4 days. Eighty-six patients (22 %) had additional intervention after pin removal (cast application in all cases). Of 389 patients, 75 (19 %) had no documented reason for extended casting, four (1 %) were extended based on physician evaluation of radiographs, and seven (2 %) were extended for other reasons. CONCLUSIONS: Elimination of radiographs at time of pin removal should be considered. If continuing to obtain radiographs at pin removal, we recommend removing pins before taking radiographs to reduce patient fear and anxiety from visualizing percutaneous pins.
