C — ComparatorStandard inhaler treatment without virtual reality
O — OutcomesAnxiety levels, fear scores, vital signs (pulse rate, respiratory rate, oxygen saturation)

Bottom Line

This RCT suggests virtual reality glasses can significantly reduce anxiety and fear in children during inhaler treatment. However, the study has important methodological limitations including significant baseline imbalances between groups and lack of outcome assessor blinding. The experimental group started with higher anxiety, fear, and pulse rates, making it difficult to attribute improvements solely to the VR intervention. While the large effect sizes are promising, the results should be interpreted cautiously. VR appears safe and may offer a useful adjunct to standard pediatric care, but higher-quality studies with better baseline balance and blinded outcome assessment are needed before routine implementation. Australian clinicians should consider this as preliminary evidence supporting VR use in pediatric settings, particularly where reducing procedural anxiety is important.

Evidence: Moderate

Key Findings

  • P Value: Fear p<0.001, Anxiety p=0.001

  • Effect Size: Fear scores: VR 0.443±0.16 vs Control 2.39±0.16; Anxiety scores: VR 0.703±0.22 vs Control 3.197±0.22

  • Primary Outcome: Fear and anxiety scores significantly reduced in VR group compared to control

  • Nnt Or Sensitivity: Not calculable from available data

  • Confidence Interval: Not reported

Clinical Application

VR technology increasingly available in Australian hospitals; requires staff training and equipment investment Could complement existing pediatric distraction techniques; aligns with patient-centred care initiatives in Australian public hospitals Children requiring inhaler therapy in hospital or clinic settings

Abstract

UNLABELLED: This study aimed to determine the effect of virtual reality (VR) glasses used during inhaler treatment on anxiety, fear and vital signs in children. The study had an experimental, randomized controlled design. Participants were assigned to groups using a lottery method based on simple randomization. The random sequence was generated by physically mixing up 30 red (experimental) and 30 white (control) cards. All the data were collected and finalized by two trained researchers (Yasemin Özyer Güvener, a nurse researcher, and Şeyma Şimşirgil Kara, a pediatrician). Participants were recruited using a convenience sampling method from among individuals who met the inclusion criteria. In terms of baseline measurements, the experimental group had significantly higher mean pulse rate, fear scores, and anxiety scores (130.23 ± 14.64, 2.77 ± 1.25, and 4.60 ± 2.04, respectively) compared to the control group (118.83 ± 17.10, 2.07 ± 1.26, and 2.80 ± 2.07, respectively) (p = 0.007, p = 0.035, and p = 0.001, respectively). For post-intervention measurements, the experimental group had significantly lower mean fear and anxiety scores (0.443 ± 0.16 and 0.703 ± 0.22, respectively) compared to the control group (2.39 ± 0.16 and 3.197 ± 0.22, respectively) (p < 0.001 and p = 0.001, respectively). CONCLUSION: It was determined that VR glasses reduced anxiety and fear, increased oxygen saturation, and reduced respiratory and pulse rates. They can thus be used as an alternative method to reduce fear and anxiety levels and balance vital signs during inhalation therapy in children. WHAT IS KNOWN: • Virtual reality (VR) is an effective non-pharmacological method for reducing pain, anxiety, and fear in pediatric patients during various medical procedures. • VR applications create a sense of presence in a virtual world, limiting the impact of anxiety and fear in clinical settings. WHAT IS NEW: • Using VR glasses during the administration of inhaled medication significantly reduces anxiety and fear levels in children compared to traditional methods. • While evidence for VR use during inhalation therapy was previously limited, this study demonstrates its effectiveness as a promising alternative to improve treatment compliance and physiological responses in pediatric patients.
