The Effects of Video Information on Delirium, Anxiety, and Nursing Satisfaction of Heart Surgery Patients

Abstract

Open heart surgery patients exhibit greater prevalence of delirium and moderate or higher level of anxiety. These symptoms may hinder postoperative recovery and health, and may even lead to complications. The objective of this study was to determine the effects of preoperative video information on delirium, anxiety, and nursing satisfaction of open heart surgery patients. This quasiexperimental study utilized a nonequivalent control group with a non-synchronized design, and was conducted from March 15, 2012 to December 1, 2014. The subjects consisted of 50 patients, of whom 25 comprised the experimental group and 25 the control group. On the day prior to surgery, the experimental group was provided with informative videos while the control group was provided with information through traditional medium. Delirium was diagnosed through CAM-ICU, while anxiety levels and Nursing Satisfaction were determined through STAI and questionnaire, respectively. Data was analyzed through SPSS WIN 21.0. The results showed no statistically significant difference (p=.260) in delirium incidences, but improvements were observed in anxiety levels (p=.028) and nursing satisfaction (p=.004). Thus, this study recommends the use of video information as part of nursing intervention for open heart surgery patients so as to reduce their anxiety levels and improve nursing satisfaction.

Overview and Strategy Analysis of Technology-Based Nonpharmacological Interventions for In-Hospital Delirium Prevention and Reduction: Systematic Scoping Review

“…Seven studies were conducted with pediatric patients [ 33 - 39 ] and 1 study was conducted with both adult and pediatric patients [ 40 ]. Most studies were prospective studies (28/31, 90%), including randomized trials [ 33 - 49 ], pretest-posttest/experimental [ 19 , 21 , 24 , 50 - 52 ], organizational case study [ 53 ], observational cohort [ 54 ], and pilot studies [ 55 - 57 ]. There were 3 retrospective studies [ 58 - 60 ] (See Table 2 for further specifications).…”

“…The interventions in these studies involved diverse technologies across the categories, that is, audio [ 33 , 49 ], light [ 42 ], sleep aids [ 19 ], communication support [ 21 ], others [ 46 ], and multiple components [ 24 , 51 , 52 ]. Of the 14 studies without significant effect on direct outcome measures, 8 studies, however, showed significant effects on delirium risk factors or symptoms, including pain [ 40 ], anxiety [ 35 , 36 , 38 , 50 ], agitation [ 54 ], hallucination [ 54 ], and factual memory encoding [ 45 ]. Six of the 8 studies using diverse technology-based interventions showed a significant effect on indirect outcome measures, including anxiety [ 39 ], agitation [ 43 ], sleep deprivation [ 44 ], or ICU readmission [ 59 ].…”

“…The interventions using video/video games were used for providing either information about the medical procedure prior to a surgery or distractions with various contents, including age-appropriate programs (eg, cartoons), family messages, or nature scenes through a handheld tablet or a specially made bedside screen. These interventions aimed to address anxiety or agitation and were effective in decreasing anxiety or agitation in all studies with either pediatric or adult patients [ 34 - 36 , 43 , 50 ]. Regarding direct delirium outcome measures, none of the studies showed a significant effect [ 34 - 36 , 50 ].…”

“…In contrast to the heterogeneity of activities and patients’ needs throughout their ICU stay, the majority of the included studies focused on a short period of time. For instance, the video and video game interventions were usually planned for less than 5 minutes [ 34 - 36 , 43 , 50 ], and the VR interventions were used for less than 15 minutes [ 37 , 38 , 57 ]. In order to minimize delirium risk factors, it is important to understand the needs and concerns of patients throughout their whole ICU stay and to develop preventive solutions that are more continuous and seamless.…”
