Implementing clinical guidelines for nutrition in a neurosurgical intensive care unit

Evidence-Based Investigation of Nurses' Nutrition Interventions in Intensive Care Patients Regarding Enteral Nutrition

AIM

The aim of this study was to examine the practices and knowledge levels of nurses regarding enteral nutrition interventions in intensive care unit patients in terms of evidence.

METHOD

This cross-sectional study was conducted in 2 hospitals between May and August 2021. A total of 136 nurses working in the intensive care units of the hospitals completed online questionnaires including demographic characteristics and questions about enteral nutrition.

RESULTS

According to the nurses' knowledge level about the indication of enteral nutrition formulas, the following were incorrect or incomplete: their knowledge about transition to parenteral nutrition in case of nutritional contraindications, what to do when the amount of gastric residual volume in tolerance is >500 mL every 6 hours, the conditions for starting enteral nutrition, and which formulas are appropriate to use. Regarding their knowledge about enteral feeding tubes/sets, their knowledge about radiologic imaging after tube placement, measurement of gastric pH level, and marking the tube location was insufficient. Differently, the correct answer percentages of the nurses in 11 of the 13 questions regarding the principles of enteral nutrition practice were above 70%.

CONCLUSION

Nurses had adequate knowledge of the principles of enteral nutrition practice, but their knowledge of the indication of enteral nutrition formulas and the evidence for enteral feeding tubes/sets varied. The results showed that nurses need to gain information about the indication of enteral nutrition formulas and evidence related to enteral feeding tubes/sets.

Implementation of the best practice in nasogastric tube feeding of critically ill patients in a neurosurgical intensive care unit

OBJECTIVES

This project was designed to implement the best practice in nasogastric tube feeding of critically ill patients in a neurosurgical intensive care unit.

METHODS

Clinical audit software programmes of the Joanna Briggs Institute (Practical Application of Clinical Evidence System and Getting Research Into Practice) were used in this project. A baseline audit, feedback, follow-up audit cycle was followed. The audit team analysed the results of the baseline audit, conducted a situational analysis and formulated and implemented a strategic plan to improve the nasogastric tube care.

RESULTS

Initially, the compliance with the criteria varied from 0% to 87%. The Getting Research Into Practice phase of the project identified several barriers of each criterion. After implementation of best practice, the following audit showed an improvement in all criteria, ranging from 33% to 95%. Marked improvement was achieved in the criteria that were not strictly required by local standards, such as rechecking the tube position, assessing the gastric residual volume and maintaining the airway cuff pressure.

CONCLUSION

The project had some success in improving the practice of nasogastric tube feeding. Collaboration, education, monitoring and a reward system were the key elements used to drive the project. Further actions and changes are expected to produce 100% compliance.

Initiating artificial nutrition support: a clinical judgement analysis

BACKGROUND

Variations in the practice of artificial nutrition are partly a result of the judgements of clinicians. Little is known about these judgements, the decision processes used or the quality of the decisions that arise. The methodology of clinical judgement analysis describes and explains judgemental differences between clinicians and offers a window into why clinician choices sometimes fail to correspond with current best practice guidelines.

METHODS

A clinical judgement analysis with 27 clinicians using two judgement tasks was carried out. Clinicians expressed their 'likelihood of feeding' and 'whether or not they would initiate artificial nutrition support' in response to 54 patient scenarios. Measures of agreement between clinicians, the degree of linear reasoning employed, their judgemental consistency and concordance with National Institute for Health and Clinical Excellence (NICE) guidelines were assessed.

RESULTS

Clinicians' judgements varied substantially both in the amount of information employed and the weighting given to information. Clinicians had only moderate agreement with NICE recommendations and overestimated the need for artificial nutrition support. Suboptimal judgements were consistently applied by clinicians. When clinicians reasoned in more linear ways, their judgements and decisions improved.

CONCLUSIONS

Overestimating the need for artificial nutritional support may inflate health service costs and increase risks for patients unnecessarily. A better understanding by clinicians of the information needed (as well as how to use it) for artificial nutrition support initiation may help improve clinical decision-making.

Bridging the guideline-practice gap in critical care nutrition: a review of guideline implementation studies

Several clinical practice guidelines focusing on nutrition therapy in mechanically ventilated, critically ill patients are available to assist busy critical care practitioners in making decisions regarding feeding their patients. However, large gaps have been observed between guideline recommendations and actual practice. To be effective in optimizing nutrition practice, guideline development must be followed by systematic guideline implementation strategies. Systematic reviews of studies evaluating guideline implementation interventions outside the critical care setting found that these strategies, such as reminders, educational outreach, and audit and feedback, produce modest to moderate improvements in processes of care, with considerable variation observed both within and across studies. Unfortunately, the optimal strategies to implement guidelines in the intensive care unit are poorly understood, with scarce data available to guide our decisions on which strategies to use. The authors identified 3 cluster randomized trials evaluating the implementation of nutrition guidelines in the critical care setting. These studies demonstrated small improvements in nutrition practice, but no significant effect on patient outcomes. There are some data to suggest that tailoring guideline implementation strategies to overcome identified barriers to change might be a more effective approach than the multifaceted "one size fits all" strategy used in previous studies. Adopting this tailored approach to guideline implementation in future studies may help bridge the current guideline-practice gap and lead to significant improvements in nutrition practices and patient outcomes.

Clinical pathways: effects on professional practice, patient outcomes, length of stay and hospital costs

BACKGROUND

Clinical pathways are structured multidisciplinary care plans used by health services to detail essential steps in the care of patients with a specific clinical problem. They aim to link evidence to practice and optimise clinical outcomes whilst maximising clinical efficiency.

OBJECTIVES

To assess the effect of clinical pathways on professional practice, patient outcomes, length of stay and hospital costs.

SEARCH STRATEGY

We searched the Database of Abstracts of Reviews of Effectiveness (DARE), the Effective Practice and Organisation of Care (EPOC) Register, the Cochrane Central Register of Controlled Trials (CENTRAL) and bibliographic databases including MEDLINE, EMBASE, CINAHL, NHS EED and Global Health. We also searched the reference lists of relevant articles and contacted relevant professional organisations.

SELECTION CRITERIA

Randomised controlled trials, controlled clinical trials, controlled before and after studies and interrupted time series studies comparing stand alone clinical pathways with usual care as well as clinical pathways as part of a multifaceted intervention with usual care.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened all titles to assess eligibility and methodological quality. Studies were grouped into those comparing clinical pathways with usual care and those comparing clinical pathways as part of a multifaceted intervention with usual care.

MAIN RESULTS

Twenty-seven studies involving 11,398 participants met the eligibility and study quality criteria for inclusion. Twenty studies compared stand alone clinical pathways with usual care. These studies indicated a reduction in in-hospital complications (odds ratio (OR) 0.58; 95% confidence interval (CI) 0.36 to 0.94) and improved documentation (OR 13.65: 95%CI 5.38 to 34.64). There was no evidence of differences in readmission to hospital or in-hospital mortality. Length of stay was the most commonly employed outcome measure with most studies reporting significant reductions. A decrease in hospital costs/ charges was also observed, ranging from WMD +261 US$ favouring usual care to WMD -4919 US$ favouring clinical pathways (in US$ dollar standardized to the year 2000). Considerable heterogeneity prevented meta-analysis of length of stay and hospital cost results. An assessment of whether lower hospital costs contributed to cost shifting to another health sector was not undertaken.Seven studies compared clinical pathways as part of a multifaceted intervention with usual care. No evidence of differences were found between intervention and control groups.

AUTHORS' CONCLUSIONS

Clinical pathways are associated with reduced in-hospital complications and improved documentation without negatively impacting on length of stay and hospital costs.

Physicians' perceptions of protocol-directed weaning in an intensive care unit in Norway

The aim of this paper is to identify physicians' perceptions of protocol-directed weaning from mechanical ventilation in an intensive care unit in Norway. Errors occur in the absence of procedures, plans, and a team culture. Standardized weaning protocols, or pathways, offer a systematic approach. The focus group method was used. Four themes emerged: (i) acceptance, where the participants perceived the protocol as having a positive influence on the weaning process, although some barriers were identified, such as its failure to facilitate the "difficult-to-wean" patient; (ii) indignant responses, which gave the impression that the protocol was prescribed for the benefit of the nurses; (iii) ambivalence was evident in the two different approaches to the weaning process when problems occurred, which were "directing" and "collaborating"; and (iv) continuity and professional competence were perceived as important aspects of the weaning process. An unclear pattern of responsibility and poor interprofessional collaboration and communication were reported.

To have and to hold nutritional control: balancing between individual and routine care. A grounded theory study

OBJECTIVES

Gaining insight into nutritional processes can help nurses and other staff in their work. The aim was to provide a theoretical understanding of the concerns and strategies of nutritional nursing care for patients with enteral nutrition in intensive care units.

DESIGN

A grounded theory approach was used. Observations of patient's nutritional care and twelve interviews with eight registered nurses and four enrolled nurses were conducted.

SETTING

The study was carried out in one intensive care unit at a medium sized hospital in Sweden.

RESULTS

The substantive theory developed included the core category "To have and to hold nutritional control - balancing between individual care and routine care". The core category was reflected in and related to the categories "knowing the patient", "facilitating the patient's involvement", "being a nurse in a team", "having professional confidence" and "having a supportive organisation". Finding a balance between individual care and routine care was a way of enhancing the patient's well-being, security and quality of care.

CONCLUSION

To have and to hold nutritional control over the patient's nutrition was found to be a balancing act between individual care and routine care. Organisation and teamwork are both challenging and supporting the provision, maintenance and development of nutritional care.

A method for implementation of nutritional therapy in hospitals

BACKGROUND AND AIMS

Many barriers make implementation of nutritional therapy difficult in hospitals. In this study we investigated whether, a targeted plan made by the staff in different departments could improve nutritional treatment within selected quality goals based on the ESPEN screening guidelines.

METHODS

The project was carried out as a continuous quality improvement project. Four different specialities participated in the study with a nutrition team of both doctors, nurses, and a dietician, and included the following methods: (1) Pre-measurement: assessment of quality goals prior to study including the use of screening of nutritional risk (NRS-2002), whether a nutrition plan was made, and monitoring was documented in the records. (2) INTERVENTION: multidisciplinary meeting for the ward staff using a PC-based meeting system for detecting barriers in the department concerning nutrition, elaboration of an action plan and implementation of the plan. (3) Re-measurement: as in (1) based on information from records and patient interviews, and an evaluation based on focus group interview with the staff. Patients who gave informed consent to participate in the study (>14 years) were included consecutively. Mann-Whitney and Kruskal-Wallis test was used for ordinal data, and Pearson chi(2) test for nominative data. P values <0.05 were considered significant. The study was performed in accordance with the Research Ethics Committee.

RESULTS

In this study 141/122 patients were included before/after the implementation period with a mean weight loss within the last 3 months of 6.2 and 5.2 kg, respectively. Before the study we found that BMI was not measured. More than half of the patients had a weight loss within the last 3 months, and 40% had a weight loss during hospitalization, and this was not documented in the records. About 75% had a food intake less than normal within the last week, and nearly one-third were at a severe nutritional risk, and only 33% of these had a nutrition plan, and 18% a plan for monitoring. Barriers concerning nutrition included low priority, no focus, no routine or established procedures, and insufficient knowledge, lack of quality and choice of menus, and lack of support from general manager of the hospital. The staff introduced individually targeted procedures including assigning of responsibility, a nutrition record, electronic calculator of energy intake, upgrading of the dieticians and special diets, communication, and educational programs. A great consistency existed between barriers for targeted nutrition effort and ideas for improvement of the quality goals between the different departments. Quality assessment after study showed an overall significant improvement of the selected quality goals.

CONCLUSION

The introduction of a new method for implementation of nutritional therapy according to ESPEN screening guidelines seems to improve nutritional therapy in hospitals. The method included assessment of quality goals, identification of barriers and individual targeted plans for each department followed by an evaluation process. The model has to be refined further with relevant clinical endpoints.
