Nutritional support is a recognized determinant of outcome in critically ill patients. Development of critical care services in low-income countries has not been accompanied by certain appropriate ancillary services and interventions, such as adequate nutritional support. This study was designed to investigate the experiences of health professionals who have provided nutritional supportive care to critically ill patients admitted to two major central hospitals in Malawi, with the aim of identifying the common practices in nutritional support in these settings.
A cross-sectional study in which 50 health professionals working in intensive care and high dependency units, admitting both adult and pediatric patients, were interviewed using a semi-structured questionnaire. Data were coded and then analyzed using SPSS version 16.0. Responses between the two hospitals were compared using Fisher's exact test.
There was no difference in the composition of respondents from the two hospitals. About 60% of respondents had had experience with nutritional supplementation in their patients-mainly enteral. The most commonly used formulations were the "ready-to-use therapeutic feeds," followed by modified milk. A high percentage of respondents (40%) reported having used dextrose solution as the sole nutritional supplement. Lack of in-service training, nonexistent nutrition protocols pertaining to acutely and critically ill patients, and a lack of clinical nutritionists were the major challenges identified.
Knowledge of nutrient supplementation was poor among the respondents. The use of ready-to-use therapeutic feeds was quite common, although there is no evidence of its effectiveness in care of acutely critically ill patients. There is a need to establish nutritional support teams in these tertiary hospitals. Clinical nutritionists would ideally help train and play leadership roles in such teams, who would be responsible for assessing patients for their nutritional needs, and ensuring that the feeds provided to patients are appropriate and adequate for their needs.
营养支持是危重症患者预后的一个公认决定因素。低收入国家重症监护服务的发展并未伴随着某些适当的辅助服务和干预措施,如充足的营养支持。本研究旨在调查为马拉维两家主要中心医院收治的危重症患者提供营养支持护理的卫生专业人员的经验,目的是确定这些环境中营养支持的常见做法。
一项横断面研究,采用半结构化问卷对50名在重症监护病房和高依赖病房工作、收治成人和儿童患者的卫生专业人员进行访谈。数据进行编码,然后使用SPSS 16.0版本进行分析。使用Fisher精确检验比较两家医院之间的回答。
两家医院的受访者组成没有差异。约60%的受访者曾在其患者中进行过营养补充——主要是肠内营养。最常用的制剂是“即食治疗性食品”,其次是改良牛奶。高比例的受访者(40%)报告曾使用葡萄糖溶液作为唯一的营养补充剂。缺乏在职培训、不存在针对急危重症患者的营养方案以及缺乏临床营养师是确定的主要挑战。
受访者对营养补充的知识掌握较差。即食治疗性食品的使用相当普遍,尽管没有证据表明其对急危重症患者护理有效。有必要在这些三级医院建立营养支持团队。临床营养师理想情况下应帮助培训并在这样的团队中发挥领导作用,该团队负责评估患者的营养需求,并确保提供给患者的食品适合其需求且足够。
