Nutritional support clinical efficacy in tuberculosis: quasi-experimental study

Abstract

ObjectiveThis study aimed to investigate the impact of nutritional support on the clinical efficacy in hospitalised tuberculosis patients with nutritional risk.MethodsWe selected a total of 266 eligible patients with tuberculosis for the experimental and 190 patients for control groups. The patients in intervention group received adjusted dietary structure, enteral nutrition via oral intake or gastric tube, total parenteral nutrition and combined enteral and parenteral nutrition. We recorded various factors, including age, sex, underlying disease, tuberculosis type, nutritional risk at admission, serum albumin (ALB), body mass index, complications during hospitalisation, nutritional support status, serum ALB before discharge and length of hospital stay.ResultsThe incidences of nutritional risk in the control and experimental groups were 64.41% and 64.72%, respectively, with no statistically significant differences in baseline characteristics. The occurrence rates of complications and secondary infections in the experimental group were 57.89% and 51.5%, respectively, which were significantly lower than the control group’s rates of 70.00% and 56.31%. These differences were statistically significant. The experimental group had a significantly shorter hospital stay (16.5±7.54 days) compared with the control group (19.55±7.33 days). Furthermore, the serum ALB levels of patients in the experimental group were higher on discharge than at admission.ConclusionHospitalised patients with tuberculosis often face a high incidence of nutritional risk. However, the implementation of standardised nutritional support treatment has shown promising results in improving the nutritional status of tuberculosis patients with nutritional risk. This approach not only helps reduce the occurrence of complications but also enhances short-term prognosis and improves overall clinical efficacy.
