ABSTRACT

Objective To investigate the situation about cognitive performance of critical care staffs in nutrition therapy for mechanical ventilated chronic obstructive pulmonary disease (COPD) patients in county hospitals.Methods A chart of questionnaire about nutrition therapy was formulated according to the current guidelines.Critical care staffs from 12 hospitals of county-level of Hang Zhou city were enrolled.The role of staffs in management of nutritional therapy for patients was observed to assess their cognitive performance and influence factors were analyzed according logistic analysis.Results A total of 137 staffs were enrolled.Almost all of the staffs thought that nutrition therapy for ventilated COPD patients was very important.About 90％ of the staffs never heard about the use of NRS2002 (nutritional risk screening 2002)to evaluation COPD patients but the rate of using it was higher among senior staffs (OR =1.08,95％ CI1.01-1.16,P =0.04).Most of staffs assess the nutritional status of patients according to biomarkers and other methods.However,doctors might assess nutritional status more often according to their experience.The majority of staffs did choose enteral nutrition for patients especially seen in doctors and senior staffs (OR =3.10 and1.13,95％ CI1.27-7.55 and 1.03-1.23,both P =0.01).For those without malnutrition,senior staffs did not choose parenteral nutrition (OR =0.14,95％ CI0.04-0.57,P =0.01).Besides,senior staffs did not continue the enteral nutrition in patients with unstable haemodynamics (OR =1.10,95％ CI1.03-1.16,P =0.002).Most of staffs considered that the head piece of bed was raised up to 30-45 degree and gastric residual volume monitoring was very important.However,compared with nurses,the cognitive performance of doctors was poorer (OR =0.39,95％ CI0.18-0.83,P =0.01).Most of staffs thought that the nutrition therapy implementation checklist was necessary but it was used in only 20％ institutions.The understanding and demand for nutritional knowledge was more urgent among doctors than nurses (OR =3.13 and 5.33,95％ CI1.45-6.75 and 1.13-25.02,P =0.004 and 0.03).Conclusions Nutrition therapy was important for ventilated COPD patients,but the staffs were not very familiar with nutritional knowledge.The cognitive performance of medical staffs was influenced by their profession and experience of practice.
