Stroke: ineffective tube securement reduces nutrition and drug treatment

Stroke patients with dysphagia often depend on nutrition, hydration and medication via nasogastric (NG) feeding tubes. Securing tubes using tape is associated with repeated tube loss. In this study, the authors determined cause and effect by auditing tube placement methods, delays incurred, duration and costs. Of 202 NG tube placements in 75 patients, 67 placements occurred in 17 patients over a full course of enteral nutrition (EN) and 40 of these placements were tracked. Tubes were secured by tape in 100%, mittens 31% and special observation 5.4%. However, over an EN course, inadvertent tube loss occurred in 82% of patients and was associated with age (p=0.049) and mitten use (p<0.001): 64% of tubes were lost due to patients and 9% slipped. Average 'tube life' was 2 days, less than 25% of the EN episode (p<0.001). While tube placement occurred within 2.55 hours of request, X-ray confirmation led to a delay in feed and drugs of 8-9 hours per tube placement and loss of 18.8% of feeding time per EN episode. Delays exceeded the 1-hour and 4-hour limits for antibiotics and other medicines in 20% and 80%, respectively. In the 17 tracked patients, it was estimated that 55% of the £5979 direct costs could be saved by nasal bridle use. In conclusion, most tubes studied were lost to inadvertent tube removal, leading to clinically significant delays to nutrition, hydration and drug treatments; this may impair recovery. Reducing tube loss is likely to reduce patient distress, treatment cost and enhance recovery.
