Background: An individual's nutritional state is an indicator of their overall health. Poor nutrition, under nutrition, vitamin deficiency and protein energy malnutrition a form of nutritional problems. In low and middle-income countries, the linkage between infectious diseases such as tuberculosis and under nutrition is critical to public health. Thus, the current study aims to explore the DOTS Providers' concerns and develop evidence-based tuberculosis patient’s nutrition assessment tool and intervention guidelines for DOTS providers, which can be quick and easy to assess.
Methods: A modified Delphi process was used to develop the nutrition assessment tool and intervention guidelines through mixed-method approach. Three rounds of the Delphi process were carried out via email, with a letter requesting to participate in the Delphi process.
Result: An in-depth interview schedule was conducted to extract themes and subthemes generating an item pool in the initial phase. The main themes identified were Perception of disease, TB cure, Association of under nutrition and TB management, Problems or difficulties encountered, Counsel, Assessment and intervention. Quantitative data analysis was performed manually by calculating the content validity index (CVI). The CVI was found to be >80% for all the items with I-CVI≥0.8 and S-CVI≥0.9. All the items were considered very essential with a score of 1.
Conclusions: The assessment tool should be subjected to other levels of evaluation that measures the suitability of the tool and interventional guidelines for the intended field.
