Experiences of health professionals with nutritional support of critically ill patients in tertiary hospitals in Malawi

Prevalence, impact, and management of adult disease-related malnutrition in African hospitals: A narrative review and insight from resource-limited clinical settings

Disease-related malnutrition (DRM) is a worldwide problem regarded as a global policy priority, but occurs on an exaggerated scale in Africa. While interpretation of studies is difficult due to the variety of nutrition assessment techniques, DRM in acute care in-patient African settings is commonly reported in the range of 45-75%, with nutritional risk reaching 84%. Challenges to the comprehensive management of DRM in the resource-limited clinical settings with few dietitians reviewed in this paper include the following: first, lack of routine nutrition screening resulting in more than 90% of malnourished or at-risk patients failing to receive nutrition support referrals, or receiving very delayed referrals. The result is worsening of nutritional status during hospital stay, clinical complications two to six times higher, up to a doubling of length of stay, and significantly higher mortality. Second, hospital structures are generally unsupportive of worthwhile nutritional care due to very poor or absent provision of nutritious oral diets, lack of multidisciplinary insight and collaboration, and the nonexistence of formalized nutrition support protocols and standards. Third, there is a grave lack of medical nutrition therapy (MNT) products and feeding pumps, forcing dietitians to improvise suboptimal formulations for enteral and parenteral feeding. Where MNT is available it is expensive and often not reimbursed, placing the responsibility for acquisition onto patients' families at their own expense. Urgent improvements in nutrition protocols adapted for resource-constrained contexts are needed, along with political commitment to facilitate the supply of suitable MNT products and equipment for use in hospitals.

The critical care nutrition landscape in sub-Saharan Africa: Field insights and clinical commentary from resource-limited clinical settings

Critical care resources are very limited on the African continent. Within these limited resources, adequate and formalized critical care nutrition support is an even rarer clinical resource. While nutrition products for nasogastric feeding are specified in international consensus guidelines as essential requirements for critical care, these are desperately undersupplied in African Intensive Care Units (ICU). Malnutrition in ICUs in low and middle income countries is 65-78%, roughly double that of developed countries. Furthermore, malnutrition prevalence among severely ill oncology and infectious disease subgroups is 90-100% in the African setting. Dietetic resources in general are few and even fewer within critical care units. Integration of dietetic skills and services into ICU care is not routine, not governed by formalized protocols and is associated with low insight from non-nutrition health professionals. Overall level of perceived critical care nutrition skill and competency is lacking. These are barriers to ICU nutritional care along with poor compliance with clinical practice guidelines, delays in nutritional referrals, insufficient dietitian-to-patient ratios and severe shortage of medical nutrition products and feeding pumps. Both enteral and parenteral nutrition are subject to improvised formulation options because commercial product acquisition and procurement is not aligned to clinical need and is seldom reimbursed through government health systems. This results in both inadequate and inappropriate nutrition delivery as well as safety concerns. Combined clinical and political strategies for incremental quality enhancements and capacity building for critical care nutrition support are urgently needed in the region.

Outcomes of High-Dose Versus Low-Dose Vitamin D on Prognosis of Sepsis Requiring Mechanical Ventilation: A Randomized Controlled Trial

Background: Critically ill patients with sepsis have a high incidence of vitamin D deficiency. Vitamin D promotes the synthesis of human cathelicidin antimicrobial peptide, a precursor of LL-37, which is a part of the innate immune system. This study investigated the effectiveness and safety of the early administration of high-dose enteral vitamin D3 in comparison with low-dose vitamin D3 in patients with sepsis requiring mechanical ventilation (MV). Methods: Eighty adult patients with sepsis requiring MV with known vitamin D deficiency were randomly assigned to receive either an enteral 50 000 IU (Group I) or 5000 IU (Group II) vitamin D supplementation. Clinical and laboratory parameters were evaluated at baseline and on days 4 and 7 between the study groups. The change in serum procalcitonin (PCT) levels on day 7 was the primary outcome, while the change in serum LL-37 levels on day 7, changes in sequential organ failure assessment (SOFA) score, and clinical pulmonary infection score on day 7, MV duration, and hospital length of stay (LOS) were the secondary outcomes. Results: The (day 7-day 0) change in serum PCT and LL-37 levels and SOFA score were significantly different in Group I (P = .010, P < .001, and P < .001, respectively). The SOFA score was significantly different on days 4 and 7 in Group I (P < .001 and P < .001, respectively). The incidence of early ventilator-associated pneumonia was significantly different between both treatment groups (P = .025). The hospital LOS was shorter in Group I (P < .001). No 25-hydroxyvitamin-D toxicity was observed in either group. Conclusions: Early enteral administration of high-dose vitamin D3 in critically ill patients with sepsis requiring MV along with standard treatment for sepsis decreased serum procalcitonin levels, increased serum LL-37 levels, and ameliorated illness severity scores.

Registered Dietitians' enteral feeding practices, obstacles, and needs during the management of critically Ill hospitalized patients in Riyadh, Saudi Arabia: A qualitative study

Objectives

Nutritional protocols and guidelines are essential to guide health-care practitioners toward effective enteral feeding management for critically ill patients. Despite the wide availability of international guidelines to direct enteral feeding practices, there are no nutritional guidelines regarding enteral feeding practices tailored for the Saudi Arabian population. In addition, different enteral feeding practices may result in negative outcomes like malnutrition.

Methods

A qualitative study was conducted through multiple focus group sessions. Pre-formulated structured open-ended questions were asked from the participants during the focus group sessions to gain an in-depth understanding of the current enteral feeding practices. All sessions were audio-recorded, and the transcript was coded and cross-validated.

Results

A total of five focus group sessions were conducted until data saturation was reached. Data saturation was reached when no additional information was mentioned in the fifth focus group session when compared to all previous sessions. All 24 participants were specialized in the clinical nutrition field with enteral feeding experience in critically ill patients and working in Riyadh city. Twelve themes of the current practices, four themes of obstacles, and four themes of needs were identified with subthemes.

Conclusion

This qualitative study shows different enteral feeding practices, obstacles, and needs among registered dietitians. Thus, the need for developing national nutritional guidelines tailored to local population characteristics is highlighted. National guidelines are recommended to be compatible with a defined registered dietitian role with clear standards of practices and responsibility for each discipline to achieve a competent health care service.

High prevalence, low identification and screening tools of hospital malnutrition in critically- ill patients in Malawi

BACKGROUND/OBJECTIVES

In Africa, approximately two-thirds of patients are at risk of malnutrition on admission and the nutritional status of patients deteriorates during hospitalization, with associated increased morbidity, mortality, and hospital-related cost. This cross-sectional study aimed at estimating rates of malnutrition in critical care units and determining the extent to which malnutrition diagnoses are documented in medical records by physicians, at two public tertiary hospitals in Malawi.

METHODS

A total of 315 adult (n = 112) and paediatric (n = 203) participants from Queen Elizabeth Central Hospital and Kamuzu Central Hospital, were included in the analysis. Nutrition status was measured by Subjective Global Assessment (SGA) and Mid-Upper Arm circumference (MUAC) and medical notes were reviewed, in both adults and paediatrics.

RESULTS

In adults, more than half were malnourished, with a higher proportion considered moderately-to-severely malnourished using SGA compared to MUAC (84.8%; 57.3%, respectively). Likewise, in paediatrics, a higher proportion was considered moderately-to-severely malnourished using SGA compared to MUAC (84.7%; 23.4%, respectively). Both adult and paediatric patients with cancer had the highest rates of malnutrition. Only 12.9% and 9.6% had documentation of malnutrition diagnosis in the medical record, for paediatrics and adult patients, respectively.

CONCLUSION

The high rates of hospital malnutrition in critically ill patients in Malawi call for comprehensive screening practices and methods; complemented by documentation of the malnutrition diagnosis and use of nutrition interventions by dietitians. This includes enteral, parenteral and supplemental nutrition as a prerequisite for patient recovery in hospitals.

Nutrition Capacity Building to Meet National Priorities: Lessons Learned in Developing and Implementing Malawi's First Dietetics Program

We describe the lessons learned in building nutrition capacity through the development and implementation of the first dietetics training program in Malawi.

The current nutrition situation in Malawi, characterized by high rates of malnutrition in communities and hospitals and a rapidly increasing burden of overweight/obesity and diet-related noncommunicable diseases, highlights the urgent need for registered dietitians, who have a proven track record in the prevention and management of all forms of malnutrition and improving patient outcomes. However, dietetics practice has been described as underdeveloped and fragmented in many parts of Africa, exacerbated by a severe and chronic shortage of dietetics professionals and a lack of nutrition and dietetic education programs in most African countries.

We share early lessons learned in the development and implementation of the first dietetics program in Malawi. Within 6 years, the program produced 10 graduate dietitians who have filled the first clinical dietitian posts in Malawian public hospitals. This early success can be attributed to the model used to develop and implement the program, which included early stakeholder engagement to define the priority skills and competencies of a Malawian dietitian, the use of internationally recognized training standards, and the development of strategic institutional partnerships that brought together complementary skills and expertise. Furthermore, using existing resources and recruiting students with a nutrition and health background accelerated implementation. The current dietetics curriculum responds to the national nutrition and health policy direction and strategic objectives. Early and sustained government engagement was crucial in creating demand and securing career prospects for graduates. Although still in its infancy, dietitians in Malawi are poised to contribute significantly to alleviating the country's complex nutrition challenges.

Systematic review of clinicians' knowledge, attitudes, and beliefs about nutrition in intensive care

Nutrition is a key component of care for critically ill patients; yet nutrition delivery is below international recommendations. In order to improve nutrition delivery to critically ill patients, an understanding of the barriers that prevent guideline adherence is required. It is known that clinicians' knowledge, attitudes, and beliefs of the role of nutrition may act as a potential barrier to nutrition delivery, but whether this remains true in critical care is unknown. The aim of this systematic scoping review was to summarize the literature exploring the knowledge, attitudes, and beliefs of clinicians around nutrition support in critically ill patients. A search of four online databases (MEDLINE via Ovid, Emcare via Ovid, PsycINFO, and CINAHL via EBSCOhost) was conducted on August 14, 2020, to identify literature that reported on clinicians' knowledge, attitudes, and beliefs of nutrition in adult intensive care patients. Data were extracted on study and participant characteristics, methodology, and key study outcomes related to nutrition. Eighteen articles met eligibility criteria and were included in the review. Key findings included the following: nutrition was seen as a priority that ranked below life-saving interventions; differences in perceived clinician responsibilities exist; common barriers to nutrition delivery included inadequate resourcing, lack of nutrition protocols, and gastrointestinal intolerance; and identified facilitators included nutrition education and the presence of a supportive multidisciplinary team. The implementation of nutrition protocols, enhanced clinical nutrition education, and further clarification of roles and responsibilities pertaining to nutrition may assist in improving nutrition delivery in critical care.

Malnutrition in Acute Care Surgery Patients in Rwanda

INTRODUCTION

Malnutrition is prevalent in hospitalized surgical patients and has been shown to significantly alter outcomes including length of hospital stay, complications, and mortality. Different tools for nutrition assessment were developed and are being used. The aim of this study was to characterize the nutritional status of acute care surgery patients, determine risk factors for malnutrition, and describe outcomes in patients with malnutrition.

METHODS

This was a prospective, descriptive study of malnutrition in acute care surgery patients at CHUK. Over a 6-month time period, we collected data on demographics, diagnosis, operation, and patient outcomes. We assessed the incidence of malnutrition using the American Society for Parenteral and Enteral Nutrition (ASPEN) guidelines and Subjective Global Assessment (SGA). We reported frequencies and percentages for categorical variables and median and interquartile range (IQR) for continuous variables.

RESULTS

We analyzed data for 279 acute care surgery patients. Most (n = 209, 73%) patients were male. The median duration of symptoms was 5 days (IQR 2, 14). The most common diagnoses were trauma (n = 83, 30%), intestinal obstruction (n = 76, 27%), and peritonitis (n = 49, 18%). Most (n = 210, 73%) patients underwent operation. The median length of hospital stay was 6 days (IQR 4, 11). Using ASPEN guidelines, 99 (35%) patients had evidence of malnutrition on hospital admission and 76 (27%) had evidence of malnutrition using SGA. After 1 week of hospital stay, 48 (41%) patients had evidence of malnutrition. Overall mortality was 3%, with higher mortality seen in patients with malnutrition (8% vs. 0.6%, p = 0.001). The length of hospital stay was longer in patients with malnutrition on hospital admission (6 days vs. 5 days, p = 0.044).

CONCLUSIONS

Acute care surgical patients present to the hospital at high-risk for malnutrition. Efforts are needed to ensure that surgical patients receive adequate nutrition support to improve patient outcomes and minimize complications.

The introduction of a paediatric nutrition support program led by a clinical dietitian at a low-resource hospital setting in Malawi

In low- and middle-income countries, nutrition support strategies are often suboptimal or non-existent in hospital settings. This is further compounded by high rates of malnutrition in these countries. The first four dietitians graduated in Malawi in 2017 providing a new opportunity to build capacity to introduce nutrition support in an acute care setting. A paediatric nutrition support program was implemented at Queen Elizabeth Central Hospital (QECH) in Blantyre, Malawi including the hiring of a local dietitian. This capacity building paper explains the development and introduction of the nutrition support program including a description of perceptions of health professionals at QECH working alongside the dietitian. In the first four months of the program at QECH, the dietitian provided nutrition support to 183 different patients across paediatric wards. Nutritional interventions predominantly included infant formula and breastmilk fortification, provision of therapeutic feeds orally or via nasogastric tubes, increased dietary protein intake for children identified to be at high risk, and nutritional counselling to caregivers. More complex nutritional interventions were also given such as the insertion of gastrostomy tubes to deliver nutrition directly to the stomach. Following the introduction of the program, qualitative interviews were done with health professionals at QECH including nurses (n = 5) and physicians (n = 11). All participants emphasized the importance and impact of the nutrition support program in enhancing the care of hospitalized children, therefore improving outcomes such as tolerability of clinical interventions, decreased duration of stay, and reduced risk of hospital readmission. In conclusion, there is a need for nutrition support provided by a dietitian for different paediatric patients which was corroborated by positive feedback from health professionals at QECH. Integration of dietitians into the healthcare system by respective Ministries of Health will require advocacy around the potential for nutrition support to strengthen the quality of care of vulnerable children.
