Development of a tool to measure dietitians' involvement in the intensive care setting

Dieticians' practices in intensive care: A national survey

BACKGROUND & AIMS

A real public health problem, namely, malnutrition in the hospital, also concerns intensive care patients. The diagnosis and prevention of malnutrition are major issues in the multidisciplinary management of patients hospitalized in the intensive care unit (ICU). To our knowledge, few data describe dietary management in French ICUs, and few international scientific publications mention professional practices or how dieticians are integrated in this type of specialized and technical sector. The objective of this study is to identify the practices of dieticians in the ICU at a national level.

METHODS

This study is based on the use of an electronic questionnaire distributed to registered dietician nutritionists practising in intensive care.

RESULTS

A total of 185 dieticians participated in this survey, which allowed us to describe the practices of 174 ICUs. Among the respondents (n = 185), 95% were women with a median age of 37 [31; 52]. The respondents graduated a median of 14 years ago [8.5; 30] and have been practising in intensive care for 5 years [2; 10]. With a median number of 12 beds [10; 18] (n = 174), the ICU has a median of 0.1 [0.05; 0.25] (n = 185) full-time equivalent dieticians. The solicitation of the dietitian is variable in different ICUs. Nevertheless, information from dietitians is frequently sought. Dietary initiatives mainly concern acts relating to oral nutrition and enteral nutrition. A nutrition protocol was present in 38% of the ICUs (n = 174). The integration felt by dieticians in the service is heterogeneous. Statistical analysis reveals that a dietitian who spends more than 4 h a week in the ICU, has a nutrition protocol in his or her department and does not encounter any obstacles, such as the absence of a doctor's prescription, is more likely to be integrated into an ICU.

CONCLUSIONS

This research work has made it possible to describe and make visible the role and involvement of dieticians working in ICUs in France and oversea departments and territories. Proposals to increase the involvement of dieticians in these sectors were reported at the end of this analysis.

Content and Face Validation of a Novel, Interactive Nutrition Specific Physical Exam Competency Tool (INSPECT) to Evaluate Registered Dietitians' Competence: A Delphi Consensus from the United States

The nutrition-focused physical examination (NFPE) is an integral component of nutrition assessment performed by registered dietitian nutritionists (RDNs) to determine signs of malnutrition and other nutrition-related complications. Increased use of this essential skill among RDNs and the transformation of dietetics education to a competency-based model in the near future calls for appropriately validated tools to measure RDNs' NFPE competence. To fill the need for a validated competency tool, this study developed an Interactive Nutrition-Specific Physical Exam Competency Tool (INSPECT) utilizing the initial 70 items identified in the first phase of the study. The second phase of this study aimed to test the preliminary version of the INSPECT for content and face validity. An expert panel of 17 members provided consensus recommendations through the Delphi process. Internal consistency of the consensus was measured with Cronbach's alpha (α) and α of ≥0.70 was defined as acceptable a priori. Inter-rater agreement among the expert panel was determined using the intraclass correlation coefficient (ICC) and an a priori ICC of 0.75 to 0.9 was established as good and >0.9 as excellent agreement. The results showed acceptable face validity (α = 0.71) and excellent content validity for the INSPECT, with an internal consistency of α = 0.97 in the first round and α = 0.96 in the second round. The inter-rater agreement was also excellent with ICC = 0.95 for each of the Delphi rounds. A total of 52 items were retained from the preliminary version of the INSPECT. Open feedback from the experts allowed for the consolidation of 11 similar items for better scoring and evaluation and thus, a total of 41 items were included in the final version of the INSPECT. The final version of the INSPECT is currently being studied in real-life, multi-site clinical settings among practicing RDNs to examine construct validity, reliability, and item-level psychometric properties. Ultimately, the validated INSPECT will be available for the competency evaluation of RDNs practicing in clinical settings.

Nutrition-related outcomes and dietary intake in non-mechanically ventilated critically ill adult patients: A pilot observational descriptive study

BACKGROUND

Critically ill patients who do not receive invasive mechanical ventilation (IMV) are a growing population, experiencing complex interventions that may impair dietary intake and nutrition-related outcomes.

OBJECTIVES

The objectives of this study were to quantify intake and nutrition-related outcomes of non-IMV critically ill patients and to establish feasibility of methods to measure nutrition-related outcomes in this population.

METHODS

Non-IMV adult patients expected to remain in the intensive care unit (ICU) for ≥24 h were eligible. Nutrition-related outcomes were assessed at baseline by subjective global assessment (SGA); on alternate study days by mid-upper arm circumference (MUAC), calf circumference (CC), and ultrasound of quadriceps muscle layer thickness (QMLT); and daily by body weight and bioelectrical impedance analysis (BIA). Data were censored at day 5 or ICU discharge. Dietary intake from all sources, including oral intake via investigator-led weighed food records, was quantified on days 1-3. Feasibility was defined as data completion rate ≥70%. Data are expressed as mean (standard deviation) or median [interquartile range (IQR)].

RESULTS

Twenty-three patients consented (50% male; 53 [42-64] y; ICU stay: 2.8 [1.9-4.0] d). Nutrition-related outcomes at baseline and ICU discharge were as follows: MUAC: 33.2 (8.6) cm (n = 18) and 29.3 (5.4) cm (n = 6); CC: 39.5 (7.4) cm (n = 16) and 37.5 (6.2) cm (n = 6); body weight: 95.3 (34.8) kg (n = 19) and 95.6 (41.0) kg (n = 10); and QMLT: 2.6 (0.8) cm (n = 15) and 2.5 (0.3) cm (n = 5), respectively. Oral intake provided 3155 [1942-5580] kJ and 32 [20-53] g protein, with poor appetite identified as a major barrier. MUAC, CC, QMLT, and SGA were feasible, while BIA and body weight were not.

CONCLUSIONS

Oral intake in critically ill patients not requiring IMV is below estimated requirements, largely because of poor appetite. The small sample and short study duration were not sufficient to quantify changes in nutrition-related outcomes. MUAC, CC, QMLT, and SGA are feasible methods to assess nutrition-related outcomes at a single time point in this population.

The speech pathology workforce in intensive care units: Results from a national survey

BACKGROUND

Admission to the intensive care unit (ICU) with mechanical ventilation can lead to patients experiencing impaired swallowing and communication function. This can negatively affect patient experiences and outcomes. There is increasing research supporting early intervention for swallowing and communication; however, there are no published ICU workforce data to determine patient access.

PURPOSE

The purpose of this study was to describe national ICU access to speech pathology (SP) services and to describe the nature of this workforce.

METHODS

Prospective audit of Australian ICUs with a focussed workforce survey of SP service including workforce demographics, clinical practices, team environments, and training was conducted. Data are described as percentage (%, n) and as median (interquartile range). Qualitative data were analysed using thematic frameworks.

RESULTS

SP services were available at 99% (n = 165) of the sites; 62 sites provided workforce data (45% response rate). Seventy-one percent of respondents serviced the ICU ≤10 h per week, with 23% reporting dedicated funding. Almost a third (32%) reported not participating in ICU team activities, and more than half of the sites (56%) did not provide ICU-specific training with resulting varied clinical confidence ratings. Facilitator and barriers both highlighted team working relationships. Facilitator themes were building working relationships, understanding the SP role in the multidisciplinary team, physical presence in the unit, and access to resources. Barrier themes were the multidisciplinary team's understanding of SP roles and lack of presence of SP services in the ICU.

CONCLUSIONS

SP services are not standard across Australian ICUs, with variations in confidence, funding, training, and team environments. Further research into the impact of these variations on patient outcomes is needed.
