Disease knowledge, medical experience, health-related quality of life and health-care costs among patients with advanced colorectal cancer in China: protocol for a nationwide multicentre survey

Abstract

BackgroundColorectal cancer (CRC) is one of the most common cancers in China. Most patients have developed advanced stage at diagnosis, leading to a low 5-year survival rate. To optimise prevention strategies, we planned a survey to evaluate the disease knowledge, medical experience and health-related quality of life (HRQOL) before and after the treatment of CRC, and healthcare costs among patients with advanced CRC in China.Methods and analysisThis is a nationwide, hospital-based, multicentre survey. Nineteen hospitals in seven cities were selected by multistage stratified sampling. Mainland China is divided into seven regions according to the traditional administrative district definition; two cities of each region were selected through simple random sampling, and then one tertiary cancer hospital and one general hospital were selected for each city. More than 4445 patients with CRC in the selected hospitals with stage III or IV will be enrolled in this study. The trained interviewers will collect information through patients’ self-report and/or medical records, including demographics and medical history; knowledge about CRC high-risk factors, screening procedure and treatment methods; medical experience on CRC screening, diagnosis and treatment; HRQOL before and after CRC treatment; and costs of CRC. All data will be input by two independent staff and verified using Epidata V.3.1 software. Data validation plan will be made to guide data checking. All statistical analyses will be conducted using SAS V.9.4 and SPSS V.24.0 software.Ethics and disseminationThe study was approved by the ethics committees of Henan Cancer Hospital, the leading participant hospital. Findings of this study will be disseminated through peer-reviewed open-access journals and presented as posters and/or oral sections in national and international conferences. Results will also be popularised to the public via media or the internet.

Analysis of the factors influencing teamwork among oncology nurses based on multigroup structural equation model

“…The implementation of ERAS can shorten the length of hospital stay, reduce complications and reduce hospitalization costs ( 11 ). For oncology nurses, it can not only reduce postoperative nursing projects, shift the focus of nurses’ work to health education, but also promote multidisciplinary communication, cultivate team members’ work responsibility, increase the depth and breadth of nurses’ knowledge, and improve their professional identity ( 25 ).…”

“…The dividing standard was 60% of nurses’ time spent participating in ERAS. Nurses with 60% or more of their time participating in ERAS were defined as the high-ERAS group, and nurses with less than 60% made up the low-ERAS group ( 11 ).…”

Real-World Utilization, Barriers, and Factors Associated With the Targeted Treatment of Metastatic Colorectal Cancer Patients in China: A Multi-Center, Hospital-Based Survey Study

“…The survey methodology was previously described [ 25 ]. In brief, China was stratified into seven geographic regions (East, North, South, Central, Northeast, Southwest, and Northwest) according to the traditional administrative district definition.…”

Prognostic value and predictive biomarkers of tumor-associated macrophages and cancer stem cells cooperatively in colorectal cancer

“…Today, despite the implementation of early diagnostic screening and the witness of available treatments such as chemotherapy, targeted therapy and immunotherapy, recurrence and metastasis of CRC are still very common, and the mortality rate remains at a very high level (3). Approximately 35% of CRC patients exhibit metastases at diagnosis, while up to 50% of patients with primarily localized disease will progress metastases, resulting in a low 5-year survival rate (4,5). CRC survival is highly reliant on early diagnosis and treatment, a dependable biomarker that can predict the prognosis as soon as possible is immediately needed.…”
