To develop a new treatment using virtual reality technology as an intervention to decrease chemotherapy-related side effects in patients with cancer
Patients chose a preferred aromatic essential oil, sound system (headphone or speakers), and content. Three virtual worlds (lake, forest, and country town) were available, and each lasted about 20 minutes. The length of the intervention depended on the length of chemotherapy. If chemotherapy was long, patients could rest and restart the intervention.
The setting was an outpatient clinic at a national cancer center hospital in Japan.
The study had a randomized, controlled design.
The following scales were used.
Emesis was measured using a VAS after the experience.
Fatigue and emesis scores showed a statistically significant decrease three to five days after chemotherapy (p < 0.05 for both symptoms). Carry-over effects were detected. Emesis was strongly related to psychological state. The intervention also was associated with decreased postinfusion emesis.
Virtual reality may be a new way to treat emesis.
