Enteral Resuscitation Nepal

Study Overview
=================
Brief Summary
-----------------
Nepal and the South Asian sub-continent carry some of the highest rates of burn injury globally, with associated high morbidity and mortality. Nepal currently has one major center equipped for comprehensive burn care, in Kirtipur, Nepal, and receives patients who are referred from around the country. At the time of presentation, most patients with major burns have had minimal to no resuscitation on arrival, and often present hours to days after the burn injury was sustained. Timely fluid resuscitation, initiated as soon as possible after a major burn injury, is the main tenet of acute burn care. Lack of adequate resuscitation in major burn injuries leads to kidney injury, progression of burn injury, sepsis, burn shock, and death. The current standard of care for major burn resuscitation is intravenous fluid resuscitation. However, in low- and middle-income countries such as Nepal, adequately trained and equipped hospitals for the treatment of burn care are not widely available (for a variety of reasons). Additionally, there is no systematic emergency medical transport system available to provide medical care and resuscitation during transport. Enteral-based resuscitation-drinking or administering fluids via the gastrointestinal tract-with substances like the WHO Oral Rehydration Solution (ORS) is recommended by burn experts and professional burn societies when resources and access to intravenous fluid resuscitation are not available. Studies have previously demonstrated the efficacy and safety of enteral-based resuscitation in controlled, high-resource settings, however, there have not been real-world effectiveness trials in resource-constrained settings. Therefore, the investigators seek to ultimately address the problem of pre-hospital and pre-burn center admission resuscitation by studying the effectiveness of enteral resuscitation with Oral Rehydration Solution (ORS) in preventing burn shock. A recent feasibility and pilot study(n=30) of this Enteral-based implementation bundle (EResus) i.e., training resources, protocol, and toolkit were conducted. The pilot study allowed for protocol development and testing, established the feasibility, provided key insights into implementation and helped develop infrastructure and study standard operating procedures at the study site. With the current study, the investigators aim to expand the trial to a full effectiveness-implementation trial, which will allow to further hone the EResus protocol and bundle, generate more effective implementation strategies, and obtain a clearer understanding of efficacy and frequency of specific outcomes. This study examines enteral-based resuscitation (i.e. enteral with/without IV Fluids) versus enhanced standard of care IV Fluids for the treatment of major burn injuries. The intervention portion of the study will entail randomization of patients presenting with acute burn injuries of 15-40% total body surface area (TBSA) to an enteral-based resuscitation versus the standard of care IV fluid resuscitation. The intervention will continue through the acute resuscitation period. The primary study variables will include measures of urine output, vital signs, planned and administered resuscitation volumes, and routes of resuscitation along with frequency, timing, and treatment of any gastrointestinal symptomology, and serious adverse events such as kidney injury and aspiration events Further, there will be a qualitative component to the study with focus group discussions of the bedside healthcare providers (doctors and nurses) caring for the enrolled patients, in order to understand the challenges and facilitators of enteral resuscitation. In-depth interviews will be conducted with enrolled patients and their families to further understand the patient perception, experience and challenges and facilitators. Qualitative analysis will be done to understand the major themes of challenges and facilitators to enteral resuscitation.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Effectiveness of enteral-based resuscitation | Measure the frequency of successful resuscitation for both enteral-based and IV fluid resuscitation protocols by measuring frequency of achieving goal average urine output of at least 0.5 mL/kg/hr per the resuscitation protocol for the overall 24 hour time period for each patient in the IV-fluid based and enteral-based resuscitation protocol arms as demonstrated on the Documentation Chart. This value will be calculated by taking the sum total of urine produced in milliliters during the resuscitation period (mL), divided by the patient's measured weight on admission in kilograms (kg), and further divided by the length of the resuscitation in hours (hr). The overall urine output in the resuscitation will be calculated for each patient. Based on the urine output and whether it achieved goal (0.5 mL/kg/hr) or not, each will be designated as successful or unsuccessful. For each intervention arm, the proportion of patients with successful resuscitation will be calculated. | 2 years | 
| Challenges and facilitators to enteral-based resuscitation and IV fluid resuscitation protocols | These are qualitative metrics of the challenges and facilitators of adherance to the IV fluid and enteral-based resuscitation protocols as described by the clinical bedside providers. These will be obtained from focus group interviews with the bedside burn care providers at the study site. The focus group interviews will occur prior to patient enrollment, halfway through patient enrollment and after the conclusion of patient enrollment. The focus group interviews will be audiorecorded, and then will undergo transcription and translated as needed for qualitative thematic analysis. A codebook will be developed and thematic analysis conducted to understand the qualitative frequency and relevancy of each cited challenge and facilitator for adhering to the resuscitation protocols. These qualitative measures will not be graded with a score, or on a scale. | 2 years | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Frequency of protocol adherence for recommended fluid adjustments | Measured frequency of adherence to the recommend fluid adjustments for both enteral-based resuscitation and IV fluid resuscitation protocols by measuring completion rate of appropriate fluid rate adjustments made, as documented in the Documentation Chart for each patient. The Documentation Chart will be analyzed for correct (appropriate) adjustment at each time check interval (every 2 hours for adults >18years,every 1 hour for Pediatric group <18 years) during the resuscitation period, as demonstrated by fluid adjustment documentation on the Documentation Chart. The assessment will be reported as the proportion of 'appropriate fluid adjustments out of total fluid adjustments, for each patient in the IV fluid resuscitation arm and each patient in the Enteral-based resuscitation arm. | 2 years | 
| Frequency of protocol adherence for documentation | Measured frequency of adherence to both enteral-based resuscitation and IV fluid resuscitation protocols by measuring completeness of documentation based on the proportion of rows filled out on the Documentation Chart during the acute resuscitation time period. This assessment will be reported as a proportion (percentage), and with a range from 0-100 percent, for each patient in the IV fluid resuscitation intervention arm and each patient in the Enteral-based resuscitation intervention arm. | 2 years | 
| Frequency of protocol adherence for laboratory assessments | Measured frequency of adherence to both enteral-based resuscitation and IV fluid resuscitation protocols by measuring completion rate of the recommended 8-hourly laboratory assessments as documented on the laboratory section of the Documentation Chart. The completeness will be measured based on the proportion of rows filled out in the laboratory section of the Documentation Chart during the acute resuscitation time period. This assessment will be reported as a proportion (percentage), and with a range from 0-100 percent, for each patient in the IV fluid resuscitation intervention arm and each patient in the enteral-based resuscitation intervention arm. | 2 years |
