Traditional and complementary medicine use among cancer patients in Nepal: a cross-sectional survey

Abstract

Background Traditional and complementary medicine (T&CM) is commonly used in South Asian countries such as Nepal. There are various causes and contributing factors for patients with cancer to consider using T&CM. However, little is known about the use of T&CM among the cancer population in this region.

Methods The study followed a cross-sectional design using a structured survey questionnaire. Survey participants were recruited from two National hospitals in Kathmandu, Nepal. The survey instrument comprised 30 questions, including variables on demographics, use of T&CM, and perceived level of disease severity, and cancer treatment. Chi-square test and logistic regression were used for data analysis using SPSS ver. 23.0.

Results Of 908 participants, 31.6% used one or more modalities of T&CM after a cancer diagnosis. The most commonly used T&CM was Ayurveda (46.5%), followed by yoga (32.4%). About 46% of T&CM users discussed their use with their doctors. The main source of information on T&CM was their family members and relatives (55.7%). Cancer type (head and neck cancer OR: 2.30, CI: 1.23–4.29; abdominal cancer OR: 2.69, CI: 1.47–4.95; lung cancer OR: 5.88, CI: 2.69–12.89), cancer stage (Stage I OR: 1.92¸CI: 1.14–3.25; Stage II OR: 1.76, CI: 1.06–2.94), and the patients’ self-rated disease severity (high perceived severity OR: 1.50, CI: 1.05–2.16) were strong predictors of T&CM use.

Conclusion This study underlined that despite the widespread use of T&CM among cancer patients in Nepal, most patients obtained information on T&CM from informal sources and did not disclose their use to physicians. To ensure the safe use of T&CM modalities, physicians should integrate questions on T&CM use into routine patient assessments in order to facilitate active communication and improve the quality of care.
