Evaluation of a Rwanda Hospital Feeding Program on Nutrition, Recovery, Costs of Care and Health Related Quality of Life

Nutritional status will be measured anthropometrically in terms of weight-for-height for all participants to calculate body mass index (BMI = kg/m2). Weight will be measured with a digital weight scale and height will be measured in recumbent position for patients unable to stand and in a standing position for other patients using a height board or a tape measure. Nutritional status will also be classified at baseline and at endline, with BMI < 18.5 considered underweight, 18.5-24.9 normal weight, 25.0-29.9 overweight, and 30.0+ obese.49 Underweight will be further classified as standard for adults and for children. For children, chronic malnutrition or stunting (low height for age) and acute malnutrition or wasting (low weight for height) will be defined according to the World Health Organization growth charts and classification standards.

LOS will be measured in days (or fractions thereof) and collected as patient record data from routine data sources, such as patient charts, by trained research assistants.

Treatment outcome will be measured with a survey tool created to assess completion and outcome of treatment and recovery during the hospitalization period from the perspective of the attending health care worker. Questions on treatment outcome will frame answers on a Likert scale. Additional qualitative questions on treatment outcome from the patients' perspective will be included on the patient discharge survey.

Costs of treatment will be measured in RWF and collected from both heath facility records of patient treatment costs as well as from patients in their discharge survey. Where precise figures are not available or recalled, such as transportation costs, estimates may be made based on available data. Costs will be measured from the patient perspective, but may also include the health service perspective to get a societal perspective.

Patient satisfaction will be measured with a survey on discharge including one open-ended question on satisfaction and another based on the Net Promoter Score (NPS). NPS has been widely used in business and in healthcare settings, including by the UK National Health Service (NHS). The open-ended survey question with reference to the NHS's most recently updated patient survey guidance.

Patient health-related quality of life is measured as a patient reported outcome and surveyed using the EuroQol EQ-5D-3L (5 dimension/3 level) health questionnaire. This standardized measure of health-related quality of life developed by the EuroQol Group is a simple, generic questionnaire for use in clinical and economic appraisal or population health status surveys. Respondents answer "no/some/extreme problems" to questions in five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. It is a point-in-time survey and was administered by trained research assistants to participants at discharge. The Kinyarwanda version is provided by EuroQol. Part 2 is a standard vertical 20 cm visual analogue scale, used in recording an individual's rating of their overall current health-related quality of life. The scale ranges from 100 ('the best imaginable health state' or 'the best health state you can imagine') to 0 ('the worst imaginable health state').

In addition to nutritional status, the study will measure food intake as a patient-reported intermediate outcome measure. Trained research assistants will survey enrolled patients daily to measure estimated quantity, content, and frequency of food intake as well as a comparison to food intake at home. The food intake surveys will also provide additional qualitative data that will be used for thematic analysis and interpretation of other outcomes.
