초록

전신 뼈 검사를 시행할 경우 검출기와 밀접한 거리로 인해 심리적 어려움을 겪고 있는 환자들이 많다. 최근 의료분야에서 가상현실(Virtual reality, VR) 장비를 사용하여 주의분산법(distraction method)을 통해 집중력이 약한 소아 환자 또는 중증 치료를 받는 환자에게 진통경감 효과를 줄 수 있다는 보고가 있다. 이에 본 논문은 핵의학 검사 시 환자들에게 심리적 안정을 주기 위해 VR 장비를 사용하였고, 이를 임상에서 활용할 수 있는지 평가해보고자 한다. VR 장비로는 ALLIP Z6 VR (ALLIP, Korea)을 사용하여 휴대전화에 연결한 후 실험을 진행하였다. 대상자는 2021년 9월 1일부터 2021년 9월 30일까지 전신 뼈 검사를 시행한 환자 30명으로 하였다. 99mTc-HDP를 정맥주사한 후 3시간~6시간 뒤에 VR 장비를 착용하고 전신영상을 얻었다. 검사 후 설문조사를 실시하였고 검사에 대한 심리적 불안도와 VR 장비에 대한 만족도는 리커트 척도 5점을 이용하였다. 설문조사에 관한 가설검증 및 신뢰도는 SPSS Statistics 25 (IBM, Corp., Armonk, NY, USA)를 통해 분석하였다. 기존 전신 뼈 검사에 대한 불안감은 3.03±1.53인 반면 VR 장비 착용 후의 불안감은 2.0±1.21으로 불안도가 34%로 감소 한 것으로 나타났다. VR 장비에 대한 환자의 집중도가 검사에 대한 불안감에 미치는 영향력을 회귀분석 했을 때 B값은 0.750 (p<0.01), t값은 6.181 (p<0.01)으로 VR 장비에 집중할수록 검사 시 불안도가 감소하고 75%의 영향력이 있음을 나타냈다. 또한 전체적인 VR 장비에 대한 만족도는 3.76±1.28이었고 재사용의사율은 66%였다. 설문지의 신뢰도계수 Cronbach α값은 0.901로 나타났다. VR 장비를 사용할 경우 환자들의 주의가 분산되면서 불안감이 감소되고 심리적으로 안정되는 효과가 나타났다. 향후 VR 장비 기술이 발전됨에 따라 장비의 소형화가 가능해지고 VR 콘텐츠영상의 해상력이 증가하는 등 보다 사실적으로 환자에게 안정감이 제공된다면 임상에서도 다양하게 활용될 수 있을 것이라 사료된다.

Purpose When performing a whole-body bone scan, many patients are experiencing psychological difficulties due to the close distance to the detector. Recently, in the medical field, there is a report that using virtual reality (VR) equipment can give pain relief to pediatric patients with weak concentration or patients receiving severe treatment through a distraction method. Therefore, in this paper, VR equipment was used to provide psychological stability to patients during nuclear medicine tests, and it is intended to evaluate whether it can be used in clinical practice. Materials and Methods As VR equipment, ALLIP Z6 VR (ALLIP, Korea) was used and the experiment was conducted after connecting to a mobile phone. The subjects were 30 patients who underwent whole-body bone examination from September 1, 2021 to September 30, 2021. After intravenous injection of 99mTc-HDP, 3 to 6 hours later, VR equipment was put on and whole body images were obtained. After the test, a survey was conducted, and a Likert scale of 5 points was used for psychological anxiety and satisfaction with VR equipment. Hypothesis verification and reliability of the survey were analyzed using SPSS Statistics 25 (IBM, Corp., Armonk, NY, USA). Results Anxiety about the existing whole-body bone test was 3.03±1.53, whereas that of anxiety after wearing VR equipment was 2.0±1.21, indicating that anxiety decreased to 34%. When regression analysis of the effect of the patient's concentration on VR equipment on anxiety about the test, the B value was 0.750 (P<0.01) and the t value was 6.181 (P<0.01). decreased and showed an influence of 75%. In addition, overall satisfaction with VR equipment was 3.76±1.28, and the intention to reuse was 66%. The Cronbach α value of the reliability coefficient of the questionnaire was 0.901. Conclusion When using VR equipment, patients' attention was dispersed, anxiety was reduced, and psychological stability was found. In the future, as VR equipment technology develops, it is thought that if the equipment can be miniaturized and the resolution of VR content images is increased, it can be used in various clinical settings if it provides more realistic stability to the patient.
