Assessing the performance and satisfaction of medical residents utilizing standardized patient versus mannequin-simulated training

Figures & data

Figure 1 A SimMan 3G Mannequin (Laerdal Medical Ltd, Orpington, UK) at the J. Wayne and Delores Barr Weaver Simulation Center at the Mayo Clinic in Jacksonville, FL, USA. The room is equipped with all the necessary supplies to simulate real-life scenarios to ensure optimum training.

Table 1 Comparison of the test scores of the two simulation groups among the four clinical scenarios

Clinical scenario	Pretest scorea		Post-test scorea		Score improvementa		P-value
	Mannequin group	Standardized patient group	Mannequin group	Standardized patient group	Mannequin group	Standardized patient group
CCB overdose	2.22	2.2	3.56	4.6	1.3	2.4	0.03
Severe sepsis	2.11	2.4	3.33	4.4	1.2	2.0	0.04
Status asthmaticus	2.78	2.6	4.11	4.6	1.3	2.0	0.02
Acute bacterial meningitis	3.11	2.9	3.78	4.5	0.7	1.6	0.17
All scenarios combined	2.56	2.53	3.69	4.53	1.2	1.8	0.01

Notes:

a Scores reported as average for 9 residents in the mannequin group and 10 residents in the standardized patient group. Full score (100%) is 5.

Abbreviation: CCB, calcium channel blocker.

Figure 2 Comparing pretest, posttest, and realism score in the four clinical simulation scenarios.

Notes: The simulation scenarios are (A) calcium channel blocker overdose; (B) severe sepsis; (C) severe asthma exacerbation; and (D) acute bacterial meningitis.
Abbreviations: SP, standardized patient.

Table 2 Realism score (reported by residents) among the four different clinical scenarios

Clinical scenario	Realism scorea		P-value
	Mannequin group	Standardized patient group
CCB overdose	2.11	4.70	0.001
Severe sepsis	2.56	4.80	0.009
Status asthmaticus	1.78	4.70	0.001
Acute bacterial meningitis	1.56	4.70	0.002
All scenarios combined	2.00	4.73	0.002

Notes:

a Numbers reported as average for 9 residents in the mannequin group and 10 residents in the standardized patient group. Highest score is 5.

Abbreviation: CCB, calcium channel blocker.

Table

1	2	3	4	5
Very fake (Did not seem real at all)	Not realistic (Minimal parts felt real)	Realistic (> 50% of the simulation felt real)	Very realistic (Almost all the simulation felt real)	Real (I could not tell the difference from reallife)
