Patients with heart disease often feel helpless and anxious because of illnesses in their vital organs. Unfamiliar environment of the intensive care unit is another factor that increases patient anxiety. This study developed audiovisual media-based information on nursing after open-heart surgery and evaluated its effect on patients' post-surgery, with the aim of reducing patients' environmental stress, anxiety, and uncertainty. This quasi-experimental study was conducted using a nonequivalent control group and non-synchronized pretest-posttest design to investigate the effect of audiovisual media-based nursing information provided prior to surgery on environmental stress, anxiety, and uncertainty in patients admitted to the cardiovascular intensive care unit after open-heart surgery. This study included 147 patients with heart disease who underwent open-heart surgery at a university hospital in South Korea. Dropouts in each group were caused by the following: for the control group, 2 were due to death, 9 discontinued, and 5 lost consciousness; for the experimental group, 2 were due to death, 6 discontinued, and 2 lost consciousness. The final number of participants investigated was 121 to 65 in the experimental group and 56 in the control group. Prior to surgery, the experimental group was provided with audio-visual information about nursing, whereas the control group was provided with written information about nursing. The environmental stress score was lower in the experimental group, 1.95 ± 0.51 points compared to 2.31 ± 0.51 points in the control group (t = 3.38, P < .001). There was a significant difference in anxiety between the mean pretest-posttest scores, with 0.39 ± 0.35 points in the experimental group, and -0.05 ± 0.58 points in the control group (t = 5.165, P < .001). On the other hand, there was a significant difference in uncertainty between the mean pretest-posttest scores, with 0.39 ± 0.4 points in the experimental group, and 0.24 ± 0.48 points in the control group (t = 4.541, P < .001). This finding indicates that providing audiovisual information regarding nursing before open-heart surgery is effective in reducing environmental stress, anxiety, and uncertainty in patients.
心脏病患者常常因为重要器官的疾病而感到无助和焦虑。重症监护病房陌生的环境也是增加患者焦虑的另一个因素。本研究开发了基于视听媒体的心脏直视手术后护理信息，并评估了其对患者术后的效果，旨在减轻患者的环境压力、焦虑和不确定性。这项准实验研究采用非等组和非同步前后测设计，调查了手术前提供基于视听媒体的护理信息对在韩国一所大学医院接受心脏直视手术后入住心血管重症监护病房的患者的环境压力、焦虑和不确定性的影响。本研究纳入了 147 名在韩国一所大学医院接受心脏直视手术的心脏病患者。每组的失访人数如下：对照组 2 例死亡，9 例退出，5 例意识丧失；实验组 2 例死亡，6 例退出，2 例意识丧失。最终实验组有 121 名患者入组，对照组有 56 名患者入组。手术前，实验组提供了护理的视听信息，而对照组提供了护理的书面信息。实验组的环境压力评分较低，为 1.95±0.51 分，而对照组为 2.31±0.51 分（t=3.38，P<.001）。实验组的焦虑在术前和术后的平均得分有显著差异，为 0.39±0.35 分，对照组为-0.05±0.58 分（t=5.165，P<.001）。另一方面，实验组在不确定性的术前和术后平均得分有显著差异，为 0.39±0.4 分，对照组为 0.24±0.48 分（t=4.541，P<.001）。这一发现表明，在心脏直视手术前提供有关护理的视听信息，可有效降低患者的环境压力、焦虑和不确定性。
