About

The goal of this observational study is to compare the effectiveness, safety, and efficiency of the simplified protocol, which includes the following three modifications: a) use of a single treatment product (RUTF), b) reduced dose, c) expanded cut-offs, with the standard protocol based on the 2023 World Health Organization (WHO) guidelines for the prevention and treatment of acute malnutrition in children aged 6 to 59 months, in outpatient care services of the states of Bolívar, Capital District, La Guaira, and Miranda of Venezuela.

The main question it aims to answer is:

What is the effectiveness, safety, and efficiency of the simplified protocol, which includes these three modifications (use of a single treatment product (RUTF), reduced dose, expanded cut-offs) when compared to a standard protocol that is based on the 2023 WHO guidelines for the prevention and treatment of acute malnutrition in children aged 6 to 59 months in the outpatient care services of the states of Bolívar, Capital District, La Guaira, and Miranda of Venezuela? This prospective cohort, longitudinal study will be conducted in 4 states, treating children aged 6-59 months diagnosed with uncomplicated AM, defined as WHZ <-2 or mid-upper-arm circumference (MUAC) <125mm or bilateral edema. Children will be prospectively followed for 16 weeks or until their recovery.

Researchers will compare the simplified protocol cohort with the standard protocol cohort to determine which one has the best effectiveness, safety, and efficiency indicators in the Venezuela context.

The effectiveness of the treatment will be measured by the recovery rate, duration of the treatment, and changes in anthropometry (weight, height, and arm circumference). Other treatment effects will also be measured, including how many are admitted to the hospital, death, and relapse rates from the nutritional program. An economic evaluation component will be incorporated. Total costs will be aggregated and presented as costs per child treated and per child recovered.

Full description

The general objective of the study is to compare the effectiveness, safety, and efficiency of the simplified protocol, which includes the following three modifications: a) use of a single treatment product (RUTF), b) reduced dose, c) expanded cut-offs, with the standard protocol based on the 2023 WHO guidelines for the prevention and treatment of acute malnutrition in children aged 6 to 59 months in outpatient care services in the states Bolívar, Capital District, La Guaira, and Miranda of Venezuela.

This will be a multicentric and prospective cohort study assessing the Simplified Protocol with the Standard Protocol, among children with uncomplicated acute malnutrition. Children will be prospectively followed until their recovery or for a maximum of 16 weeks.

The study will be implemented in 4 Venezuelan states chosen based on their acute malnutrition prevalence and operational constraints.

The protocol will be implemented by health professionals from each institution, duly previously trained in applying the study protocol.

MAM (Although MAM cases are not traditionally included, in this study they will be incorporated if they meet the following criteria):

• MUAC ≥ 115 mm to < 125 mm or
• Weight-Height/length Z Score ≥ -3 to < -2 and
• No nutritional oedema

And at least one the following:

Trial design

299 participants in 2 patient groups

Simplified protocol

Description:

The first cohort will be composed of all children between 6 and 59 months of age who attend predefined outpatient care points in the states Distrito Capital, Miranda, and La Guaira. These children must meet the inclusion criteria for the research. For those selected in these centers, the method of nutritional treatment for acute malnutrition will be the simplified protocol. Adaptations in this protocol include: 1. Use of a single treatment product (Ready to use therapeutic food). 2. Reduced dose. 3. Expanded cut-offs.

Treatment:

Procedure: Simplified protocol

Standard protocol

Description:

The second cohort will be composed of all children between 6 and 59 months of age who attend other predefined outpatient care points in the four states and met the inclusion criteria for this research. Nutritional treatment will be administered to these children, following the WHO Standard Protocol.
