Registered Dietitian Nutritionists’ Role in Hospital in Home

Hospital in Home (HIH) is the delivery of acute care services in a patient’s home as an alternative to hospitalization.¹ Compared with traditional inpatient care, HIH programs have been associated with reduced costs, as well as patient and caregiver satisfaction, diseasespecific outcomes, and mortality rates that were similar or improved compared with inpatient admissions.^1-4

The US Department of Veterans Affairs (VA) Veterans Health Administration (VHA) and other hospital systems are increasingly adopting HIH models.^2-4 At the time of this writing, there were 12 HIH programs in VHA (personal communication, D. Cooper, 2/28/2022). In addition to physicians and nurses, the interdisciplinary HIH team may include a pharmacist, social worker, and registered dietitian nutritionist (RDN).^2,5 HIH programs have been shown to improve nutritional status as measured by the Mini Nutritional Assessment Score, but overall, there is a paucity of published information regarding the provision of nutrition care in HIH.⁶ The role of the RDN has varied within VHA. Some sites, such as the Sacramento VA Medical Center in California, include a distinct RDN position on the HIH team, whereas others, such as the Spark M. Matsunaga VA Medical Center in Honolulu, Hawaii, and the James A. Haley Veterans’ Hospital in Tampa, Florida, consult clinic RDNs.

Since HIH programs typically treat conditions for which diet is an inherent part of the treatment (eg, congestive heart failure [CHF]), there is a need to precisely define the role of the RDN within the HIH model.^2,3,7 Drawing from my experience as an HIH RDN, I will describe how the inclusion of an RDN position within the HIH team is optimal for health care delivery and how HIH practitioners can best utilize RDN services.

RDN Role in HIH Team

Delegating nutrition services to an RDN enhances patient care by empowering HIH team members to function at the highest level of their scope of practice. RDNs have been recognized by physicians as the most qualified health care professionals to help patients with diet-related conditions, such as obesity, and physicians also have reported a desire for additional training in nutrition.⁸ Although home-health nurses have frequently performed nutrition assessments and interventions, survey results have indicated that many nurses do not feel confident in teaching complex nutritional information^.9 In my experience, many HIH patients are nutritionally complex, with more than one condition requiring nutrition intervention. For example, patients may be admitted to HIH for management of CHF, but they may also have diabetes mellitus (DM), obesity, and low socioeconomic status. The HIH RDN can address the nutrition aspects of these conditions, freeing time for physicians and nurses to focus on their respective areas of expertise.^9,10 Moreover, the RDN can also provide dietary education to the HIH team to increase their knowledge of nutritional topics and promote consistent messaging to patients.

Including an RDN on the HIH team enables patients to have comprehensive, personalized nutrition care. Rather than merely offering generalized nutrition education, RDNs are trained to provide medical nutrition therapy (MNT), which has been shown to improve health outcomes and be cost-effective for conditions such as type 2 DM, chronic kidney disease, hypertension, and obesity.^10,11 In MNT, RDNs use the standardized 4-stepnutrition care process (NCP).¹² The Table shows examples of how the NCP can be applied in HIH settings. Furthermore, in my experience, MNT from an RDN also contributes to patient satisfaction. Subjective observations from my team have indicated that patients often express more confidence in managing their diets by the time of HIH discharge.

RDNs can guide physicians and pharmacists in ordering oral nutrition supplements (ONS). Within the VHA, a “food first” approach is preferred to increase caloric intake, and patients must meet specific criteria for prescription of an ONS.¹³ Furthermore, ONS designed for specific medical conditions (eg, chronic kidney disease) are considered nonformulary and require an RDN evaluation.¹³ Including an RDN on the HIH team allows this evaluation process to begin early in the patient’s admission to the program and ensures that provision of ONS is clinically appropriate and cost-effective.

Care Coordination

HIH is highly interdisciplinary. Team members perform their respective roles and communicate with the team throughout the day. RDNs can help monitor patients and alert physicians for changes in blood glucose, gastrointestinal concerns, and weight. This is especially helpful for patients who do not have a planned nursing visit on the day of an RDN evaluation. The HIH RDN can also collaborate with other team members to address patient needs. For example, for patients with limited financial resources, the HIH RDN can provide nutrition education regarding cooking on a budget, and the HIH social worker can arrange free or low-cost meal services.
