Effect of nutritional interventions on discharged older patients: study protocol for a randomized controlled trial

Educational nutritional intervention to prevent loss of health-related quality of life among older adults after a surgical treatment: design of a randomised controlled trial

BACKGROUND

Disease-related malnutrition after a hospital stay has major consequences for older adults, the healthcare system and society. This study aims to develop and test the effectiveness of an educational video to prevent loss of health-related quality of life among live-at-home older adults after surgical treatment in a hospital.

METHOD

This randomised controlled trial will occur at a regional hospital in Norway. Participants will be live-at-home adults aged 65 years and older. They will be recruited from three different surgical departments after a surgical procedure. Individuals with a body mass index below 24 and a home address in one of nine selected municipalities will be eligible for inclusion. Participants will be randomly assigned to either the intervention group or the control group. Those assigned to the intervention group will obtain access to a 6-min educational video 5 days after being discharged from the hospital. The control group will not obtain access to the video. The primary outcome will be health-related quality of life using the Norwegian Rand 36-Item Short Form Health Survey. Furthermore, we will measure body composition, number of readmissions and nutritional knowledge at inclusion and 3-month follow-up.

DISCUSSION

This randomised controlled trial is expected to provide insight into whether an educational video can improve the nutritional status of older adults following a surgical procedure and discharge from the hospital. The findings will be useful for assessing how videos offering nutritional advice to older adults who have undergone a surgical procedure can improve their health-related quality of life, reduce loss of function, prevent readmission to hospital and reduce healthcare costs.

Clinical Interventions to Improve Nutritional Care in Older Adults and Patients in Primary Healthcare - A Scoping Review of Current Practices of Health Care Practitioners

In light of the increasing life expectancy of Europe's population and the rising significance of active and healthy ageing relating thereto, an integrated approach of nutritional care within primary health care is gaining importance. The aim of the review was to summarize evidence on the effectiveness of nutritional interventions in primary health care. The scoping review is based upon a comprehensive literature search of relevant literature published between January 2010 and August 2021 in PubMed, CINAHL, Cochrane Database of Systematic Reviews, Embase and Medline databases. Overall, 15 studies were included for evidence synthesis and interventions were basically clustered according to their type, into 1) eHealth and tele-medical interventions; 2) targeted single interventions; and 3) comprehensive, multi-faceted interventions. The review presents diverging evidence regarding the efficacy and effectiveness of interventions for nutritional care in primary health care, however, demonstrates encouraging outcomes. eHealth and tele-medical interventions partly show a careful positive tendency. Likewise, manifold single interventions on patient level present significant improvements in patient health outcomes. Multifaceted and comprehensive interventions found in the literature also partly demonstrate significant changes in intervention groups. Primary health care represents a critical setting for the care of older citizens and patients with complex health needs. This scoping review provides an overview of current nutrition care practices in primary health care and results reinforce the need to strengthen implementation of multi-faceted interventions carried out by the inter-disciplinary primary care team for advanced nutritional care.

A multimodal nutritional intervention after discharge improves quality of life and physical function in older patients - a randomized controlled trial

BACKGROUND

Many older hospitalized patients are at nutritional risk or malnourished and the nutritional condition is often further impaired during hospitalization. When discharged to own home, a "Nutrition Gap" often occurs, causing inadequate dietary intake, and potentially impeded recovery. Previously, cross-sectorial studies of single component nutritional intervention have shown a limited effect on clinically relevant outcomes. We hypothesized that a multimodal nutritional intervention is necessary to elicit a beneficial effect on clinically relevant outcomes.

METHODS

A randomized controlled trial was performed for a period of 16 weeks. At discharge, the intervention group (IG) received dietetic counselling including a recommendation of daily training, an individual nutrition plan and a package containing foods and drinks covering dietary requirements for the next 24 h. Further, a goodie-bag containing samples of protein-rich milk-based drinks were provided. Information regarding recommendations of nutritional therapy after discharge was systematically and electronically communicated to the municipality. The dietician performed telephone follow-ups on day 4 and 30 and a home visit at 16 weeks. The control group (CG) received standard treatment. The primary outcome was readmissions within 6 month, secondary outcomes were Length of Stay (LOS), Health Related Quality of Life (EQ-5D-3L), nutritional status, physical function (30s-CST) and mortality. This trial was registered under ClinicalTrials.gov Identifier no. NCT03488329.

RESULTS

We included 191 patients (IG: n = 93). No significant difference was seen in readmissions within 6 month (IG: 45% vs. CG: 45%, Risk Ratio (RR): 0.96 0.71-1.31, p = 0.885). At the 16-weeks follow-up more patients in the IG reached at least 75% of energy and protein requirements (82% vs. CG: 61%, p = 0,007). The energy (kcal) and protein intake (g) per kg was significantly higher in the IG (26.4 kcal/kg (±7.4) vs. 22.6 (±7.4), p = 0.0248) (1.1 g/kg (±0.3) vs. 0.9 g/kg (±0.3). Furthermore, significant lower weight loss was seen in IG (0.7 (±4.3) vs. -1.4 (±3.6), p = 0.002). A significant and clinically relevant difference was found in the EQ-5D-3L VAS-score (IG: mean 61.6 ± 16.2 vs. CG: 53.3 ± 19.3, p = 0.011) (Δ14.3 (±15.5) vs. Δ5.6 (±17.2), p = 0.002). A significant difference in mean 30s-CST in IG was also found (7.2 (±4.3) vs. 5.3 (±4.1), p = 0.010). The improvements in physical function were of clinical relevance in both groups, but significantly higher in the IG (Δ4.2 (±4.4) vs. Δ2.2 (±2.5), p = 0.008). In fact, 86% in IG experienced improvements in the 30s-CST compared with 68% in the CG (p = 0.022). LOS was found to be lower at all time points, however not significant (30 days: -3 (-8.5 to 2.5), p = 0.276, 16 weeks: -4 (-10.2 to 2.2, p = 0.204), 6 months: -3 (-9.3 to 3.3, p = 0346)). All-cause mortality was not different between groups, however RR showed a non-significantly 47% reduction at day 30 (0.53 (0.14-2.05, p = 0.499)) and a 17% reduction at 16 weeks (0.83 (0.40-1.73, p = 1.000)) in IG. Per protocol (PP) analysis revealed a non-significant decrease of 32% in readmission at 6 months (RR: 0.68 (0.42-1.08), p = 0.105).

CONCLUSION

The present study, using a multimodal nutritional approach, revealed no significant effect on readmissions however a significant positive effect on nutritional status, quality of life and physical function was found. The improvements in quality of life and physical function were of clinical relevance. No significant effect was found on LOS and mortality.

Does a 12-Month Transitional Care Model Intervention by Geriatric-Experienced Care Professionals Improve Nutritional Status of Older Patients after Hospital Discharge? A Randomized Controlled Trial

At hospital discharge, many older patients are at health and nutritional risk, indicating a requirement for ongoing care. We aim to evaluate the effects of comprehensive individualized care by geriatric-experienced care professionals, the so-called “pathfinders”, on nutritional status (NS) of older patients after discharge. A total of 244 patients (median age 81.0 years) without major cognitive impairment were randomized to Intervention Group (IG: 123) or Control Group (CG: 121) for a 12-month intervention, with up to 7 home visits and 11 phone calls. The comprehensive individualized care contained nutritional advice, when required. The intervention effect after three (T3m) and 12 (T12m) months on change in MNA-SF (Mini Nutritional Assessment-Short Form) and BMI was evaluated by Univariate General Linear Model (ANOVA), adjusted for age, sex, living situation, and activities of daily living. At baseline, mean MNA-SF did not differ between IG and CG (10.7 ± 2.6 vs. 11.2 ± 2.5, p = 0.148); however, mean BMI was significantly lower in IG compared to CG (27.2 ± 4.7 vs. 28.8 ± 4.8 kg/m², p = 0.012). At T3m, mean change did not differ significantly between the groups, neither in MNA-SF (0.6; 95%CI: −0.1–1.3 vs. 0.4; −0.3–1.1, p = 0.708) nor in BMI (−0.2; −0.6–0.1 vs. 0.0; −0.4–0.4 kg/m², p = 0.290). At T12m, mean change of MNA-SF was significantly higher in IG than in CG (1.4; 0.5–2.3 vs. 0.0; −0.9–0.8; p = 0.012). BMI remained unchanged in IG, whereas it slightly declined in CG (0.0; −0.7–0.6 vs. −0.9; −1.6–−0.2 kg/m², p = 0.034). We observed rather small effects of comprehensive individualized care by pathfinders on NS in older patients 12 months after discharge. For more pronounced effects nutrition expertise might be needed.
