Enteral nutrition in critically ill adults: Literature review of protocols.

BACKGROUND: Managing nutrition in critically ill patients is an important intervention to promote healing. It is unknown whether the implementation of a protocol that guides enteral nutrition (EN) support is effective in improving the outcomes of critically ill patients. Furthermore, it is unknown whether a nurse-driven protocol is more or less effective than a protocol not managed by nurses. AIMS AND OBJECTIVES: The purpose of this literature review is to determine the current state of the science regarding evidence-based protocols for the administration and management of EN in critically ill patients. SEARCH STRATEGY, INCLUSION, AND EXCLUSION CRITERIA: Studies were identified by searching the Cumulative Index to Nursing and Allied Health Literature Plus database for the terms "enteral nutrition AND nursing." Studies with EN protocols for adult, critically ill patients published since 2011 were included. Studies without a protocol and those pertaining to paediatric, disease-specific, medical-surgical, or community-based populations were excluded. A total of 10 studies meeting the inclusion criteria were identified. CONCLUSIONS: Defining and implementing both early initiation of EN and adequate titration to goal are important for achieving the maximum nutritional advantage. The highest benefit is also derived from identifying and delivering an individualized caloric and/or protein goal. A protocol increases standardization of practice in relation to these themes as well as the management of gastric residual volume, complications, and potentially for managing feeding interruptions. Because of the significant effects of nursing care on nearly all aspects of the management and delivery of EN, a nurse-driven protocol may yield higher compliance and greater effectiveness than a protocol that is not nurse driven. RELEVANCE TO CLINICAL PRACTICE: Nurses are at the forefront of EN administration, although interprofessional collaboration remains paramount. Current practice must align with the best practice in the development and implementation of an EN protocol.

Tandem gait abnormality in Parkinson disease: Prevalence and implication as a predictor of fall risk.

INTRODUCTION: We report the prevalence of abnormal tandem gait (TG) in patients with idiopathic Parkinson disease (PD) and its association with symptoms of subjective unsteadiness, falls, freezing of gait, and cognitive impairment. METHODS: We assessed subjective balance impairment, fall history, antero-posterior postural instability, and TG in PD patients (Hoehn and Yahr (HY) stage 0-4). We recorded the age, sex, current medications, HY stage, Schwab and England (S&E) scale score, and MOCA score for each patient. Logistic regression was used to evaluate age-adjusted associations between TG and other demographic and clinical factors. RESULTS: A total of 102 patients with PD were assessed. Of those, 63.5% of HY 2 patients and 100% of HY 2.5 and 3 patients had a TG abnormality. The presence of TG abnormality was associated with subjective imbalance, falls, freezing of gait, S&E < 80, and MOCA score <24 after adjustment for age. CONCLUSIONS: TG abnormality is common in PD, precedes the development of antero-posterior postural instability, is associated with cognitive impairment, and may predict fall risk. A longitudinal study will help determine if TG is a predictor of impending progression from HY 2 to HY 3.
