To evaluate the impact of a laboratory course on the manual blood pressure (BP) and heart rate (HR) measurement skills of pharmacy students.
After 1 lecture and 1 laboratory session on vital sign technique, pharmacy students enrolled in a patient assessment laboratory course were randomly paired with a classmate and manually measured the classmate's BP and HR. Within 2 minutes, the BP and HR were measured by an Omron 711-AC automatic monitor. The same assessment procedures with manual and automatic measurements were repeated near the end of the laboratory course. Student skills were also evaluated through direct observation by faculty members.
Student and machine measurements of systolic blood pressure (SBP), diastolic blood pressure (DBP), and HR significantly correlated at the final assessment (r = 0.92, 0.83, and 0.91 respectively; p < 0.001 for each. The proportion of student and device values agreeing to within 5 units (mmHg and beats-per-minute) at baseline versus at the final assessment significantly improved from 38% to 67% for SBP, 51% to 77% for DBP, and 52% to 79% for HR (p < 0.001 for each). The percentage of students correctly performing all 13 AHA endorsed steps for BP measurement improved significantly from 4.6% to 75.6% (p < 0.001).
Significant improvement and the attainment of competency in manual vital signs measurement were demonstrated by pharmacy students after 11 weeks of skill rehearsal in a laboratory course.
评估一门实验课程对药学专业学生手动测量血压(BP)和心率(HR)技能的影响。
在参加了一次关于生命体征测量技术的讲座和一次实验课后,参加患者评估实验课程的药学专业学生被随机与一名同学配对,手动测量该同学的血压和心率。在2分钟内,使用欧姆龙711-AC自动监护仪测量血压和心率。在实验课程接近尾声时,重复进行相同的手动和自动测量评估程序。学生的技能也通过教师的直接观察进行评估。
在最终评估中,学生测量值与机器测量值的收缩压(SBP)、舒张压(DBP)和心率显著相关(分别为r = 0.92、0.83和0.91;每项p < 0.001)。在基线时与最终评估时,学生测量值与设备测量值在5个单位(mmHg和每分钟心跳数)范围内一致的比例,SBP从38%显著提高到67%,DBP从51%提高到77%,HR从52%提高到79%(每项p < 0.001)。正确执行美国心脏协会认可的所有13个血压测量步骤的学生百分比从4.6%显著提高到75.6%(p < 0.001)。
药学专业学生在实验课程中经过11周的技能训练后,手动生命体征测量技能有显著提高并达到了合格水平。
