Treatment changes can negatively affect patients' prognosis and may be psychologically burdensome. The aim of this study was to explore whether COVID-19-related treatment changes (delays, cancellations, changes) influenced fear of cancer recurrence, anxiety, and depression in breast cancer patients. A convenience sample (n = 154) of patients who were diagnosed with breast cancer no longer than 2 years ago was obtained from an online community and social network site. The survey content included COVID-19-related treatment experiences and psychological status. The data were analyzed using descriptive statistics, χ2 test, independent t test, and analysis of variance. Twenty-nine patients (18.8%) had experienced COVID-19-related treatment changes, and changes of the treatment plan had a significant correlation with depression (t = 2.000, P = .047). Fear of cancer recurrence was high (mean score, eiving timely supportive care to alleviate fears and anxiety and assess financial needs for COVID-19-related costs. As the vein structure gets damaged in patients receiving chemotherapy treatment, placement of peripheral intravenous catheter becomes difficult. To increase the success of peripheral intravenous catheter placement, a vein imaging device and fist clenching can be used. The aim of this study was to determine the effect of using a vein imaging device or fist clenching on the determination of an appropriate vein and successful catheter placement time in adult patients receiving chemotherapy. One hundred thirty-five patients receiving chemotherapy were randomly assigned to either the vascular imaging device group (n = 45), the fist clenching group (n = 45), or the control group (n = 45). In the vascular imaging group, a vascular imaging device was used to determine the appropriate vein; in the fist clenching
