How Much Does Dysphagia Cost? Understanding the Additional Costs of Dysphagia for New Zealand in Patients Hospitalised with Stroke.

INTRODUCTION: Dysphagia (i.e., disordered swallowing) is a consequence of stroke. Existing literature on the marginal cost of dysphagia after stroke is limited and ignores long-term impacts. Our aim was to determine the marginal 12-month cost attributable to dysphagia, including health-related quality of life (HRQoL) impacts, among patients hospitalised with stroke in New Zealand. METHODS: Secondary analysis of observational data from the REGIONS Care study, a national study from New Zealand of consecutively hospitalised patients with acute stroke between May 1, 2018, and October 30, 2018, including an outcome survey at 12 months among those who provided consent. Patients were identified as dysphagic if they received a swallow screen in hospital resulting in a speech language therapist review. Patients that required a nasogastric feeding tube in hospital were classified as "severe." Optimal linear propensity score matching was utilised to provide a group of patients to compare with stroke and dysphagia. All costs were converted to 2021NZD. RESULTS: Overall, of the 2,379 patients in the REGIONS cohort (51% male, median age: 78), 40% (944/2,379) were dysphagic (52% male, median age: 78), and 5% (111/2,379) were classified as severely dysphagic. Within 12 months of hospital discharge, dysphagia reduced HRQoL overall by 0.06 index points (95% CI: 0.028-0.100), and severe dysphagia by 0.12 index points (95% CI: 0.03-0.20). The estimated marginal 12-month cost attributable to stroke-related dysphagia was NZD 24,200 on average per patient. This estimate includes the additional hospitalisation costs (NZD 16,100), community rehabilitation services (NZD 570), hospital level aged residential care (NZD 4,030), and reduced HRQoL (NZD 3,470) over a 12-month period post-hospital discharge. The overall total marginal cost for those with severe dysphagia was NZD 34,000 per patient. CONCLUSION: We report cost estimates to 12 months from a national perspective on the additional costs and HRQoL outcomes of dysphagia for people hospitalised with stroke in New Zealand. Findings provide a novel contribution internationally since few prior studies have extended beyond the acute hospital phase of care. By quantifying the economic burden, we provide information to decision makers to improve dysphagia management strategies and ultimately enhance the overall HRQoL for people with stroke and dysphagia.

Estimating the Incidence and Prevalence of Dysphagia in New Zealand.

Dysphagia imposes a substantial economic burden on global healthcare systems due to its pervasive, high-cost nature. To comprehend this burden, we must first assess dysphagia's prevalence and incidence in the general population. Existing studies on dysphagia prevalence encompass minor symptoms, while it is the severe cases that drive significant healthcare costs. We address this knowledge gap by estimating dysphagia incidence and prevalence in the New Zealand population, projecting future demographics of affected individuals. Incidence and prevalence rates of dysphagia within specific underlying medical conditions are sourced from existing literature. Median projected population estimates from Statistics New Zealand, by age, sex, and ethnicity are used to calculate dysphagia projections. Where possible, projections by age and ethnicity are provided until 2038 and projections by age and sex until 2073. In 2020, 9300 New Zealanders are estimated to have newly developed dysphagia while 1.5% of the general New Zealand population are estimated to have been living with the effects of the condition. By 2073, the number of individuals newly diagnosed annually is projected to increase to 24,500 and the prevalence of dysphagia is projected to increase to 2.6%. These results indicate that a significant number of New Zealanders are impacted by dysphagia. This number is predicted to dramatically increase in the future, mostly due to population ageing, indicating an increased burden on society and healthcare systems. Our work provides a useful starting point for countries worldwide to assess future healthcare resource demands associated with dysphagia, assisting with healthcare provision planning.

The Drug Burden Index and Level of Frailty as Determinants of Healthcare Costs in a Cohort of Older Frail Adults in New Zealand.

OBJECTIVES: Frailty is common in older people and is associated with increased use of healthcare services and ongoing use of multiple medications. This study provides insights into the healthcare cost structure of a frail group of older adults in Aotearoa, New Zealand. Furthermore, we investigated the relationship between participants' anticholinergic and sedative medication burden and their total healthcare costs to explore the viability of deprescribing interventions within this cohort. METHODS: Healthcare cost analysis was conducted using data collected during a randomized controlled trial within a frail, older cohort. The collected information included participant demographics, medications used, frailty, cost of service use of aged residential care and outpatient hospital services, hospital admissions, and dispensed medications. RESULTS: Data from 338 study participants recruited between 25 September 2018 and 30 October 2020 with a mean age of 80 years were analyzed. The total cost of healthcare per participant ranged from New Zealand $15 (US dollar $10) to New Zealand $270 681 (US dollar $175 943) over 6 months postrecruitment into the study. Four individuals accounted for 26% of this cohort's total healthcare cost. We found frailty to be associated with increased healthcare costs, whereas the drug burden was only associated with increased pharmaceutical costs, not overall healthcare costs. CONCLUSIONS: With no relationship found between a patient's anticholinergic and sedative medication burden and their total healthcare costs, more research is required to understand how and where to unlock healthcare cost savings within frail, older populations.
