Implementation of a Student-Teacher-Based Blended Curriculum for the Training of Medical Students for Nasopharyngeal Swab and Intramuscular Injection: Mixed Methods Pre-Post and Satisfaction Surveys

BACKGROUND

The COVID-19 pandemic caused a major disruption in the health care sector with increased workload and the need for new staff to assist with screening and vaccination tasks. Within this context, teaching medical students to perform intramuscular injections and nasal swabs could help address workforce needs. Although several recent studies discuss medical students' role and integration in clinical activities during the pandemic, knowledge gaps exist concerning their role and potential benefit in designing and leading teaching activities during this period.

OBJECTIVE

The aim of our study was to prospectively assess the impact in terms of confidence, cognitive knowledge, and perceived satisfaction of a student-teacher-designed educational activity consisting of nasopharyngeal swabs and intramuscular injections for the training of second-year medical students in the Faculty of Medicine, University of Geneva, Switzerland.

METHODS

This was a mixed methods pre-post surveys and satisfaction survey study. Activities were designed using evidence-based teaching methodologies based on the SMART (specific, measurable, achievable, realistic, and timely) criteria. All second-year medical students who did not participate in the activity's old format were recruited unless they explicitly stated that they wanted to opt out. Pre-post activity surveys were designed to assess perception of confidence and cognitive knowledge. An additional survey was designed to assess satisfaction in the mentioned activities. Instructional design was blended with a presession e-learning activity and a 2-hour practice session with simulators.

RESULTS

Between December 13, 2021, and January 25, 2022, a total of 108 second-year medical students were recruited; 82 (75.9%) students participated in the preactivity survey and 73 (67.6%) in the postactivity survey. Students' confidence in performing intramuscular injections and nasal swabs significantly increased on a 5-point Likert scale for both procedures-from 3.31 (SD 1.23) and 3.59 (SD 1.13) before the activity to 4.45 (SD 0.62) and 4.32 (SD 0.76) after the activity (P<.001), respectively. Perceptions of cognitive knowledge acquisition also significantly increased for both activities. For the nasopharyngeal swab, knowledge acquisition concerning indications increased from 2.7 (SD 1.24) to 4.15 (SD 0.83), and for the intramuscular injection, knowledge acquisition concerning indications increased from 2.64 (SD 1.1) to 4.34 (SD 0.65) (P<.001). Knowledge of contraindications for both activities increased from 2.43 (SD 1.1) to 3.71 (SD 1.12) and from 2.49 (SD 1.13) to 4.19 (SD 0.63), respectively (P<.001). High satisfaction rates were reported for both activities.

CONCLUSIONS

Student-teacher-based blended activities for training novice medical students in commonly performed procedural skills seem effective for increasing their confidence and cognitive knowledge and should be further integrated within a medical school curriculum. Blended learning instructional design increases students' satisfaction about clinical competency activities. Future research should elucidate the impact of student-teacher-designed and student-teacher-led educational activities.

[Near-drowning in children]

From 1971 to 1977 a total of 32 nearly-drowned children were admitted to the University Pediatric Hospital, Berne, and the Children's Hospital, Lucerne. 5 died within 15 h to 10 days. Neurological damage was seen in 5 cases. 20 children were under 5 years of age and only 8 over 7 years. All cases with fatal consequences or severe cerebral sequel had cardiac arrest on admission. A maximal possible submersion time for survival without consequences has not been found. The pathophysiology of fresh water drowning and current treatment are summarized. Situations leading to near drowning are specified and some aspects of prognosis discussed.

Atypical phenylketonuria caused by 7, 8-dihydrobiopterin synthetase deficiency

A patient with atypical phenylketonuria and normal liver dihydropteridine reductase and phenylalanine-4-hydroxylase activities excreted neopterin but not biopterin or dihydrobiopterin in urine. The oral administration of L-sepiapterin (1 mg/kg body weight) lowered serum-henylalanine from 17.1 to 1.1 mg/dl within 6 h. Comparable responses were observed after oral administration of L-erythro-7, 8-dihydrobiopterin or L-erythro-5, 6, 7, 8-tetrahydrobiopterin (each given in a dose of 2.5 mg/kg body weight). The results indicate a 7, 8-dihydrobiopterin synthetase deficiency in the patient.
