Information Disclosure to Cancer Patients in Mainland China: A Meta-analysis

Objective: This study aims to systematically examine Chinese cancer patients' and families' preferences for information disclosure to the patient, patient awareness, and predictors of patient awareness.

Methods: The Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines were followed. Web of Science, Scopus, Proquest, Taylor & Francis Online, and China National Knowledge Infrastructure were searched in April 2022 and Chinese Biomedical Literature Database in July 2022 for quantitative studies. The Mixed Methods Appraisal Tool was used for quality assessment.

Results: A total of 22 studies were included, and the average quality score was 0.65/1. Meta-analyses showed that 89.6% and 81.8% of cancer patients wanted to know their diagnosis and prognosis, respectively. Meanwhile, 50.0% and 32.4% of families prefer diagnosis disclosure and prognosis disclosure to the patient, respectively. Significantly more patients than families favored disclosure to the patient. In reality, only 59.3% of cancer patients know their diagnosis, and 19.9% know their prognosis. For predictors, while patients' gender, cancer type (breast cancer or not), treatment method (operation or other), or complications (yes or no) do not influence diagnosis awareness, being younger, being married, having higher educational attainment, having early-stage rather than late-stage cancer, and being in a higher-grade hospital all predict better chances of knowing a diagnosis. No study explored predictors of patients' prognosis awareness. The findings did not vary according to publication time or sample size.

Conclusions: Chinese cancer patients are eager to know their diagnosis and prognosis, but families are hesitant about disclosure to the patient, and patients' awareness is low. While cultural, legal, and medical backgrounds lay the foundation for information disclosure in Mainland China, case-by-case practical factors also make a difference.
