To improve nursing home (NH) staff delivery of oral liquid nutritional supplements between meals to residents with a history of weight loss.
Pre-Post intervention study.
Two skilled nursing homes.
Eighteen long term care residents.
At baseline all participants had a non-specific physician's order to receive a nutritional supplement. The intervention consisted of specifying the physician's order as follows: "Give 4 oz high protein supplement at 10 am, 2 pm, and 7 pm".
Research staff conducted direct observations for two days during and between meals for a total of 4 days, or 12 possible observation periods per participant before and one week following the intervention. Research staff documented NH staff delivery of snacks (including high protein supplements) and amount consumed (fluid ounces) for the high protein supplements using a standardized protocol during each observation period.
Before the specific order was written participants were offered any type of snack an average of 1.82 times per day and a high protein supplement 0.59 times per day. After the specific order was written participants were offered any type of snack an average of 1.59 times per day and a high protein supplement 0.91 times per day. There were no statistically significant differences in the average number of times snacks or supplements were offered before and after the specific order was written. The proportion of snacks offered that were high protein supplements did increase after the specific order was written (p<0.001). When a high protein supplement was provided, most residents consumed 100% of it.
Oral liquid nutritional supplements were not provided consistent with orders in NH practice. The specificity of the order related to type of supplement and time of delivery did not influence when and how often supplements are provided to residents but it did influence the type of nutritional supplement offered.
改善养老院工作人员在两餐之间为有体重减轻史的居民提供口服液体营养补充剂的情况。
干预前后研究。
两家专业养老院。
18名长期护理居民。
在基线时,所有参与者都有一份非特定的医生医嘱以接受营养补充剂。干预措施包括将医生医嘱明确如下:“上午10点、下午2点和晚上7点各给予4盎司高蛋白补充剂”。
研究人员在干预期间及干预前后各进行两天的直接观察,共4天,每位参与者在干预前和干预后一周各有12个可能的观察时段。研究人员在每个观察时段使用标准化方案记录养老院工作人员提供零食(包括高蛋白补充剂)的情况以及高蛋白补充剂的摄入量(液量盎司)。
在写下特定医嘱之前,参与者平均每天获得任何类型零食的次数为1.82次,获得高蛋白补充剂的次数为0.59次。写下特定医嘱之后,参与者平均每天获得任何类型零食的次数为1.59次,获得高蛋白补充剂的次数为0.91次。写下特定医嘱前后,提供零食或补充剂的平均次数没有统计学上的显著差异。写下特定医嘱之后,提供的零食中高蛋白补充剂的比例确实有所增加(p<0.001)。当提供高蛋白补充剂时,大多数居民会全部喝完。
在养老院的实际操作中,口服液体营养补充剂的提供与医嘱不一致。与补充剂类型和给药时间相关的医嘱特异性并未影响何时以及多频繁地向居民提供补充剂,但确实影响了所提供营养补充剂的类型。
