Comparison of peer-led versus professional-led training in basic life support for medical students

Figures & data

Figure 1 Flow of participants through trial.

Notes:^aDid not return for evaluation 20 weeks after basic life support (BLS) training. ^bDeclined evaluation. The data are presented as means ± standard deviation.

Table 1 Demographic characteristics of student participants

	Peer-led group	Professional-led group
Age (years)	23.6 ± 1.5	24.0 ± 1.3
Height (cm)	164.8 ± 7.5	167.3 ± 7.5
Weight (kg)	57.4 ± 12.9	58.0 ± 9.0

Note: Values are mean ± standard deviation.

Table 2 Comparison of outcome measures between peer-led group and professional-led group

Chest compression	Peer-led group	Professional-led group	Difference of means (95% CI) or P value*
Compression depth (mm)	43.5 ± 7.6	42.8 ± 9.5	0.75 (−4.5 to 6.0)
Percent compression with adequate depth (38–51 mm) (%)	54.5 ± 31.9	52.5 ± 35.6	2.0 (−18.7 to 22.8)
Proportion of participants with adequate compression depth, n (%)	16/23 (69.6)	12/22 (54.5)	P = 0.299
Compression rate (per minute)	104.3 ± 9.1	109.6 ± 10.6	−5.3 (−14.4 to 3.7)
Proportion of participants with adequate compression rate (90–110/minute), n (%)	17/23 (73.9)	8/22 (36.4)	P = 0.011
Questionnaire scores
I mmediately after BLS training	18.2 ± 1.4	18.0 ± 1.7	0.27 (−0.45 to 0.99)
At 20 weeks after BLS training	17.2 ± 2.3	17.8 ± 2.0	−0.57 (−1.72 to 0.57)

Notes: Values are mean ± SD unless otherwise specified;

* chi-square test.
