Barriers and Enablers to Delegating Malnutrition Care Activities to Dietitian Assistants

The Deployment and Utilization of the Allied Health Professions Support Workforce: A Scoping Review

The demand for healthcare services internationally continues to increase, exacerbated by patient backlogs resulting from the COVID-19 pandemic and the difficulties in recruiting and retaining healthcare staff. These difficulties have led to increased interest in workforce redesign, and the upskilling of existing staff in all areas of healthcare, including within the Allied Health Professions (AHP). Clinical support staff are a key component of workforce redesign, yet little has been documented on the utilization of this workforce across the wide range of professions that collectively form the AHP workforce. Existing research is also unclear due to the variety of titles used to describe them (eg, allied health assistants, therapy assistants, etc). This study aimed to review how Support Workers and Assistant Practitioners (SWAPs) are utilized within the AHP professions. Electronic databases (MEDLINE, CINAHL complete, Scopus, and Google Scholar) were searched to find English Language primary research articles that explored the deployment of clinical support staff within Allied Health. Following the scoping review methodology, data from each study were analyzed in terms of design, key findings, and implications. A quality assessment was also completed. Thirty-nine articles met the eligibility criteria. Studies were undertaken in Australia, UK, and USA, and covered a range of AHPs and methodological approaches. Most articles employed qualitative methods, with highly variable research quality identified. Key findings were that cost-effectiveness of this workforce has not been formally evaluated in any setting or AHP discipline, and that support workers are a largely underutilized staff group potentially due to inconsistencies in their deployment and scope of practice, and the lack of a clear career pathway. Rigorous, quantitative, and mixed methods research into the deployment and impact of this staff group is needed in order to gain a clearer understanding of how they are optimally utilized across the different AHP disciplines.

Use and safety of enteral nutrition protocols in acute care: A scoping review of literature and retrospective audit of practice

AIM

Standardised enteral nutrition protocols are recommended in critical care, however their use and safety are not well described in other inpatient populations. This mixed methods study reports on the use and safety of enteral nutrition protocols for non-critically ill adults.

METHODS

A scoping review of published literature was conducted. In addition a retrospective audit of practice at an Australian tertiary teaching hospital with an existing hospital-wide standardised enteral nutrition protocol was performed. Data on use, safety and adequacy of enteral nutrition prescription were collected from medical records for patients receiving enteral nutrition on acute wards (January-March 2020).

RESULTS

Screening of 9298 records yielded six primary research articles. Studies were generally low quality. Published literature suggested that protocols may reduce time to enteral nutrition initiation and goal rate, and improve adequacy of nutrition provision. No adverse outcomes were reported. From the local audit of practice (105 admissions, 98 patients), enteral nutrition commencement was timely (median 0 (IQR 0-1) days from request; goal rate: median 1 (IQR 0-2) days from commencement and adequate (nil underfeeding), without prior dietitian review in 82% of cases. Enteral nutrition was commenced per protocol in 61% of instances. No adverse events, including refeeding syndrome, were observed.

CONCLUSIONS

Most inpatients requiring enteral nutrition can be safely and adequately managed on enteral nutrition protocols. Evaluation of protocols outside of the critical care setting remains a gap in the literature. Standardised enteral nutrition protocols may improve delivery of nutrition to patients, whilst allowing dietitians to focus on those with specialised nutrition support needs.

Are Malnourished Inpatients Treated by Dietitians Active Participants in Their Nutrition Care? Findings of an Exploratory Study of Patient-Reported Measures across Nine Australian Hospitals

BACKGROUND

Inpatient malnutrition is a key determinant of adverse patient and healthcare outcomes. The engagement of patients as active participants in nutrition care processes that support informed consent, care planning and shared decision making is recommended and has expected benefits. This study applied patient-reported measures to identify the proportion of malnourished inpatients seen by dietitians that reported engagement in key nutrition care processes.

METHODS

A subset analysis of a multisite malnutrition audit limited to patients with diagnosed malnutrition who had at least one dietitian chart entry and were able to respond to patient-reported measurement questions.

RESULTS

Data were available for 71 patients across nine Queensland hospitals. Patients were predominantly older adults (median 81 years, IQR 15) and female (n = 46) with mild/moderate (n = 50) versus severe (n = 17) or unspecified severity (n = 4) malnutrition. The median length of stay at the time of audit was 7 days (IQR 13). More than half of the patients included had two or more documented dietitian reviews. Nearly all patients (n = 68) received at least one form of nutrition support. A substantial number of patients reported not receiving a malnutrition diagnosis (n = 37), not being provided information about malnutrition (n = 30), or not having a plan for ongoing nutrition care or follow-up (n = 31). There were no clinically relevant trends between patient-reported measures and the number of dietitian reviews or severity of malnutrition.

CONCLUSIONS

Malnourished inpatients seen by dietitians across multiple hospitals almost always receive nutritional support. Urgent attention is required to identify why these same patients do not routinely report receiving malnutrition diagnostic advice, receiving information about being at risk of malnutrition, and having a plan for ongoing nutrition care, regardless of how many times they are seen by dietitians.
