Change in symptom clusters perioperatively in patients with lung cancer.

PURPOSE: To describe the trajectory, number, and types of symptom clusters at three time points (i.e., day of admission [T1], 2-4 days postoperatively [T2], and 1 month postoperatively [T3]) using ratings of symptom occurrence and severity and to identify the changes in these symptom clusters over time in patients with lung cancer. METHODS: We analysed the data of 217 lung cancer patients who received surgical treatment at a tertiary hospital affiliated to Anhui Medical University, in Hefei City, China. The occurrence and severity of 19 symptoms at all points of measurement were measured using the general and lung cancer modules of the M.D. Anderson Symptom Inventory. Exploratory factor analysis was performed to extract the symptom clusters. RESULTS: Seven symptom clusters were identified across symptom dimensions. However, only three of them (i.e., lung cancer specific, sleep disturbance, and nervous system) were relatively stable across dimensions and time. Two symptom clusters varied over time but not with dimensions (nutritional and gastrointestinal). The other two symptom clusters (psychological and respiratory) differed in terms of time and dimensions. CONCLUSIONS: Findings may provide insights into the seven identified clusters and overall stability of three symptom clusters in lung cancer patients perioperatively.

Psychometric Testing of the Chinese Version of Supportive Care Needs Survey for Partners and Caregivers of Cancer Patients.

The objective of this study was to test the psychometric properties of the Chinese version of the Supportive Care Needs Survey for Partners and Caregivers (SCNS-P&C-C) among the caregivers of Chinese patients with cancer. The original English version of SCNS-P&C was translated into Chinese using a forward and backward translation approach. The psychometric properties of the SCNS-P&C-C including factor structure, convergent, and discriminative validities and internal consistency were then tested. A convenience sample of 498 caregivers of hospitalized patients with cancer was recruited from oncology units in three tertiary public hospitals in Hefei city, mainland China. Exploratory factor analysis revealed four domains of the SCNS-P&C-C, which resemble the original English version scale. The convergent validity of the SCNS-P&C-C has established with statistically significant correlations between the SCNS-P&C-C and the Chinese version of Kessler Psychological Distress Scale (r = 0.327, P < 0.01). The SCNS-P&C-C has also good internal consistency with Cronbach's alpha coefficients ranging from 0.79 to 0.89 for the four subscales and 0.94 for the total scale. The Chinese version of the SCNS-P&C was found to be reliable and valid to assess the supportive care needs for partners and caregivers of Chinese patients with cancer. The SCNS-P&C-C can be used to assess and understand the supportive care needs of Chinese caregivers of patients with cancer. Such information will help the healthcare professionals to formulate tailored supportive care services for the caregivers of Chinese patients with cancer.
