The influence of surgical and procedural rotations and interest in a surgical discipline on medical students' suturing ability during clerkship.

BACKGROUND: Although suturing is an essential competency for medical students, there has been limited research into the skills acquisition process over the course of medical school curriculum. This study aimed to determine whether suturing ability improved over the course of clerkship and whether an interest in a surgical discipline was associated with improved skill acquisition. METHODS: The suturing ability of third-year medical students at a large Canadian medical school was assessed at the beginning of clerkship (August 2018) as well as before and after their surgery rotation by 2 expert reviewers using a validated, objective scoring system as well as a qualitative assessment, both in person and via blinded video recordings. Students were randomly allocated to 4 groups for their clerkship year by the medical school. RESULTS: Of 133 eligible students, 115 (86.5%) completed the study. Median suturing assessment scores improved significantly after the surgery rotation (214.5 [interquartile range (IQR) 191.1-235.0] v. 238.0 [IQR 223.5-255.0], p = 0.001). Groups that had completed a procedural rotation (emergency medicine, obstetrics and gynecology) between clerkship and starting their surgery rotation had improved scores between these time points (p < 0.05), whereas scores decreased for groups that did not have a procedural rotation between assessments. Regardless of previous rotations, suturing scores were similar between groups after the surgery rotation. The 21 students (18.3%) who were interested in a surgical discipline had higher suturing scores than students who were not interested in surgery at the beginning of clerkship (229.1 [IQR 220.2-253.0] v. 208.0 [IQR 185.0-228.0], p < 0.001) and after the surgery rotation (252.0 [IQR 227.0-268.0] v. 235.8 [IQR 220.5-251.2], p = 0.02). CONCLUSION: Medical students' suturing ability improved during the surgery rotation but was also influenced by other procedural rotations and students' interest in procedure specialties. Skill acquisition by medical students is complex and requires additional investigation.

Management of Pediatric Patients With Spontaneous Pneumomediastinum: A Retrospective Chart Review.

PURPOSE: Given the paucity of data on pediatric spontaneous pneumomediastinum (SPM), management is largely informed by extrapolation from adult studies or personal clinical experience, resulting in significant heterogeneity. The purpose of this study was to describe how pediatric patients with SPM are clinically managed at our institution and propose a treatment algorithm. METHODS: Retrospective chart review of pediatric patients with SPM from April 2002 to December 2021 at a single Canadian tertiary care center. Data on medical history, presentation characteristics, clinical management, and complications were gathered. Descriptive and inferential statistics were used to analyze data. RESULTS: We identified 63 patients for inclusion, median age was 15 years. Twenty-nine patients were transferred from another facility. Most common presenting symptoms were chest pain (72.3%), shortness of breath (44.6%), and subcutaneous emphysema (21.5%). Initial workup included chest x-ray (93.6%), CT scan (20.6%), and upper GI series (7.9%). There was no difference in the number of initial tests between admitted and discharged patients (p = 0.10). Of admitted patients (n = 35), 31.4% had primary SPM (no underlying comorbidity/inciting event) and 68.8% were secondary SPM (underlying comorbidity/inciting event). No patients with primary SPM developed complications or recurrences. In contrast, 16.7% of those with secondary SPM developed complications and 54.2% had at least one additional intervention after admission. DISCUSSION: There is significant variability in diagnostic investigation and treatment of pediatric SPM at our center. Amongst primary SPM, additional tests did not change complication rate or recurrence, including those transferred from another facility. An expeditious treatment algorithm is warranted. TYPE OF STUDY: Retrospective Cohort Study. LEVEL OF EVIDENCE: III.

Pregnant women's perception of risk with use of the H1N1 vaccine.

OBJECTIVE: During the H1N1 influenza pandemic in 2009, The Motherisk Program, a counselling service providing teratology information, received many calls from pregnant women inquiring about the safety of the H1N1 vaccine. We wished to explore pregnant women's perception of risk and the factors associated with deciding whether or not to receive the vaccine. METHODS: Pregnant women who called Motherisk between October 1 and November 30, 2009, requesting counselling regarding the safety of the H1N1 vaccine, and who had not yet received the vaccine, were contacted for follow-up using a structured questionnaire. RESULTS: One hundred thirty women completed the questionnaire; 104 (80%) had received the H1N1 vaccination following their call to Motherisk, and 26 (20%) had not. More than 70% of the women cited confusing and frightening information in the media as a trigger for their concern, prompting them to call Motherisk. Sixty percent stated that information from their primary health care providers or Motherisk contributed to their decision making. CONCLUSION: The H1N1 vaccination rate in pregnant women who contacted Motherisk was higher than the rate in the general population, as many followed Motherisk's recommendation to receive the vaccine. During this period, the media appeared to provide pregnant women with confusing information. In any future pandemic scare, accessibility to primary health care providers or specialized information services such as Motherisk will be key to providing guidance for pregnant women.
