Inpatient gastrostomy in Huntington's disease: Nationwide analysis of utilization and outcomes compared to amyotrophic lateral sclerosis

Palliative care in advanced Huntington's disease: a scoping review

BACKGROUND

As Huntington's disease (HD) is a progressive disease for which there is no cure yet, patients in the advanced stage of HD may benefit from palliative care.

OBJECTIVE

To review the literature focusing on palliative care in advanced stage HD, and the level of evidence.

METHODS

Publications between 1993 and October 29th, 2021 from 8 databases (Embase, Web of Science, Cochrane, Emcare, PsycINFO, Academic Search Premier, PMC PubMed Central and Pubmed) were included. The literature was deductively classified based on topics that are part of the definition of palliative care, or as care-related topics that emerged from the literature. Levels of evidence I (high) - V (low) were determined as defined by the Joanna Briggs Institute.

RESULTS

Our search resulted in 333 articles, 38 of which were included. The literature covered four domains of palliative care: physical care, psychological care, spiritual care, and social care. Four other topics in the literature were: advance care planning, end-of-life needs assessments, pediatric HD care, and need for health care services. Most literature was underpinned by a low level of evidence, except for the topics on social care (Level III-V), advance care planning (Level II-V) and end-of-life needs assessments (Level II-III).

CONCLUSIONS

To deliver adequate palliative care in advanced HD, both general and HD-specific symptoms and problems need to be addressed. As the level of evidence in existing literature is low, further research is essential to improve palliative care and to meet patient's wishes and needs.

Health Services in Huntington Disease: A Systematic Literature Review

Purpose of Review

Clinical trials for Huntington disease (HD) have primarily focused on managing chorea and, more recently, the development of disease-modifying therapies (DMTs). Nonetheless, understanding health services among patients with HD is essential for assessing new therapeutics, development of quality metrics, and overall quality of life of patients and families with HD. Health services assess health care utilization patterns, outcomes, and health care-associated costs, which can help shape the development of therapeutics and aid in policies that affect patients with a specific condition. In this systematic literature review, we analyze data of published studies looking at causes of hospitalization, outcomes, and health care costs in HD.

Recent Findings

The search yielded 8 articles published in the English language and comprising data from the United States, Australia, New Zealand, and Israel. The most common cause of hospitalization among patients with HD was dysphagia or dysphagia-related complications (e.g., aspiration pneumonia or malnutrition), followed by psychiatric or behavioral symptoms. Patients with HD had more prolonged hospitalizations than non-HD patients, and it was most prominent among those with advanced disease. Patients with HD were more likely to be discharged to a facility. A small percentage received inpatient palliative care consultation, and behavioral symptoms were a primary cause of discharge to another facility. Interventions such as gastrostomy tube placement had associated morbidity, and it was common among patients with HD with a diagnosis of dementia. Palliative care consultation and specialized nursing care were associated with more routine discharges and fewer hospitalizations. In terms of cost, patients with HD with private and public insurances had the highest expenditure with more advanced disease, and expenses were associated with hospitalization and medication costs.

Summary

In addition to DMTs, HD clinical trial development should also consider the leading causes of hospitalization, morbidity, and mortality in patients with HD, including dysphagia and psychiatric disease. No research study, to our knowledge, has systematically reviewed health services research studies in HD. Evidence from health services research is needed to evaluate the efficacy of pharmacologic and supportive therapies. This type of research is also critical in understanding health care costs associated with the disease and to better advocate and shape policies that can benefit this patient population.

Disparities in Palliative Care Utilization Among Hospitalized People With Huntington Disease: A National Cross-Sectional Study

BACKGROUND

People with Huntington's disease (HD) often become institutionalized and more frequently die away from the home setting. The reasons behind differences in end-of-life care are poorly understood. Less than 5% of people with HD report utilization of palliative care (PC) or hospice services, regardless of the lack of curative therapies for this neurodegenerative disease. It is unknown what factors are associated with in-patient specialty PC consultation in this population and how PC might be related to discharge disposition.

OBJECTIVES

To determine what HD-specific (e.g., psychosis) and serious illness-specific factors (e.g., resuscitation preferences) are associated with PC encounters in people with HD and explore how PC encounters are associated with discharge disposition.

DESIGN

We analyzed factors associated with PC consultation for people with HD using discharge data from the National Inpatient Sample and the Nationwide Inpatient Sample (NIS), Healthcare Cost and Utilization Project (HCUP), Agency for Healthcare Research and Quality. An anonymized, cross-sectional, and stratified sample of 20% of United States hospitalizations from 2007 through 2014 were included using ICD-9 codes.

RESULTS

8521 patients with HD were admitted to the hospital. Of those, 321 (3.8%) received specialty PC. Payer type, (specifically private insurer or other insurer as compared to Medicare), income, (specifically the top quartile as compared to the bottom quartile), mortality risk, D.N.R., aspiration pneumonia, and depression were significantly associated with PC in a multivariate model. Among those who received PC, the odds ratio (OR) of discharge to a facility was 0.43 (95% CI, 0.32-0.58), whereas the OR of discharge to home with services was 2.25 (95% CI 1.57-3.23), even after adjusting for possible confounders.

CONCLUSIONS

Among patients with HD, economic factors, depression, and serious illness-specific factors were associated with PC, and PC was associated with discharge disposition. These findings have implications for the adaptation of inpatient PC models to meet the needs of persons with HD.
