Factors associated with assisted ventilation use in amyotrophic lateral sclerosis: a nationwide population-based study in Korea

Burden and preparedness of care partners of people living with amyotrophic lateral sclerosis at home in Korea: A care partner survey

INTRODUCTION/AIMS

The care burden of people living with amyotrophic lateral sclerosis (pALS) increases with disease progression. This study aimed to investigate the home care status and preparedness of care partners of pALS (cALS) in Korea.

METHODS

An online survey was conducted with family care partners of patients diagnosed with ALS for over 1 year in 2022. The data collected included care time, depression evaluated using the patient health questionnaire-9 (PHQ-9), preparedness for caregiving scale (PCS), and caregiver competence scale (CCS). Results were compared based on whether the pALS underwent a tracheostomy or not.

RESULTS

Ninety-eight cALS of 98 pALS participated in the study, of whom 59 pALS had undergone tracheostomy. Among the cALS, 60.2% were spouses, and 34.7% were children. The cALS took care of the patients for 13 (8-20) hours/day (median, interquartile range [IQR]) on weekdays and 15 (10-24) h/day on weekends. Among the cALS, 91.8% were depressed, and 28.6% had severe depression. The median (IQR) PCS and CCS scores were low (11/32 (8-15) and 8/20 (8-11), respectively), and both were lower in those caring for patients without than with tracheostomy (p < .001 and p < .02, respectively). Most cALS (77.6%) wished to continue caring for their pALS at home.

DISCUSSION

Family care partners of pALS spend more than half of each day caring for patients and are often depressed. Most cALS preferred providing care at home, but felt ill-prepared. Designing home-based medical care is necessary for pALS to thrive at home.

Percutaneous gastrostomy, mechanical ventilation and survival in amyotrophic lateral sclerosis: an observational study in an incident cohort

OBJECTIVE

To analyze disease-modifying effects of percutaneous endoscopic gastrostomy (PEG) insertion for supporting nutrition, noninvasive ventilation (NIV), and tracheostomy-assisted ('invasive') ventilation (TIV) in amyotrophic lateral sclerosis (ALS).

METHODS

We retrospectively analyzed survival in a large population-based incident cohort that was prospectively followed up in our center. Analysis considered several known ALS-related prognostic variables.

RESULTS

In this population, PEG and NIV in multivariable analysis significantly correlated to survival as computed by disease onset to death/tracheostomy. NIV was associated with better survival while PEG was associated with reduced survival. Other independent prognostic factors were age at ALS onset, diagnostic delay, and flail arm/leg and pure upper motor neuron (PUMN) phenotypes. The length of survival after TIV was significantly associated with age at ALS onset (inverse correlation) whereas other variables did not. The length of survival after TIV correlated to age at ALS onset in such a way that each additional year of age at ALS onset decreased survival by about 0.7 months. Patients who underwent both TIV and NIV did not experience a better survival than those who underwent TIV alone.

CONCLUSION

The lack of effect of enteral nutrition on ALS survival probably reflected the timing of PEG insertion in patients with more severe disease. By contrast, patients who used mechanical ventilation had an increased overall survival compared with non-ventilated ones. The study also provided new information showing that the combined use of NIV and TIV did not may prolong ALS survival as compared to TIV alone.

Healthcare Utilization and Supportive Care Timing in South Korean People Living With Amyotrophic Lateral Sclerosis: A Single-Center Retrospective Study

BACKGROUND AND PURPOSE

Despite the growing demands and challenges faced by patients with amyotrophic lateral sclerosis (ALS) in accessing healthcare services, our understanding of this access remains poor. This study aimed to investigate the healthcare utilization patterns and timing of nutritional and respiration support in patients with ALS in South Korea.

METHODS

A retrospective cohort study was conducted on patients diagnosed with ALS at a single tertiary hospital between 2016 and 2019 and followed up for 2 years. We evaluated patient characteristics, healthcare utilization (hospital admissions, outpatient visits, and emergency department [ED] visits), and the timing of nutritional and respiration support (noninvasive positive pressure ventilation [NIPPV], tracheostomy, gastrostomy, and nasogastric tube) at 6-month intervals from the first outpatient visit.

RESULTS

Among the 143 included patients, 73.4% were admitted at least once, 18.9% experienced unplanned admissions, and 30.1% visited the ED at least once during the study period. The most-common reason for ED visits was neurological symptoms during the first 6 months (59.1%), followed by respiratory symptoms. One fifth of patients who visited the ED underwent tracheostomy (20.9%) or NIPPV (20.9%). Two years after the first visit, 32.2% used a ventilator, and 13.3%, 26.6%, and 6.3% had undergone tracheostomy, gastrostomy, and nasogastric tube insertion, respectively.

CONCLUSIONS

During the 2 years following their first outpatient visit, 20% of patients with ALS experienced unplanned admissions and 30% visited the ED. An active and prompt supportive-care program should be implemented to ensure timely functional support in order to reduce these risks of unplanned admissions.

Epidemiology and characteristics of emergency department utilization by patients with amyotrophic lateral sclerosis in Korea from 2016 to 2020: A nationwide study

INTRODUCTION/AIMS

Patients with amyotrophic lateral sclerosis (ALS) inevitably visit the emergency department (ED) due to their increased risk of respiratory failure and mobility limitations. However, nationwide data on ED visits by patients with ALS are limited. This study investigated the characteristics of patients with ALS-related ED visits.

METHODS

We conducted a cross-sectional study from 2016 to 2020, utilizing a nationwide ED database. The total number of patients with ALS who visited the ED and their primary reasons for visiting/diagnoses were analyzed.

RESULTS

In total, 6036 visits to the ED were made by patients with ALS. Of these, 41.8% arrived by ambulance and 27.7% spent >9 h in the ED. Following ED treatment, 57.4% were hospitalized, including 19.3% admitted to the intensive care unit (ICU) and 5.4% who died in the hospital. The primary reasons for ALS-related ED visits were dyspnea (35.2%), feeding tube problems (10.1%), fever (7.8%), and mental status changes (3.6%). The most common diagnoses were pneumonia (14.5%), respiratory failure (5.7%), dyspnea (5.5%), aspiration pneumonia (4.3%), and tracheostomy complications (3.4%).

DISCUSSION

Reasons for ED visits for patients with ALS include acute respiratory distress, as well as concerns related to tube feeding and tracheostomy. To reduce the risk of patients with ALS requiring ED visits, it is essential to ensure the provision of timely respiratory support and high-quality home-based medical care teams that can support and address patients before their condition deteriorates.

Towards clinical application of implantable brain-computer interfaces for people with late-stage ALS: medical and ethical considerations

Individuals with amyotrophic lateral sclerosis (ALS) frequently develop speech and communication problems in the course of their disease. Currently available augmentative and alternative communication technologies do not present a solution for many people with advanced ALS, because these devices depend on residual and reliable motor activity. Brain-computer interfaces (BCIs) use neural signals for computer control and may allow people with late-stage ALS to communicate even when conventional technology falls short. Recent years have witnessed fast progression in the development and validation of implanted BCIs, which place neural signal recording electrodes in or on the cortex. Eventual widespread clinical application of implanted BCIs as an assistive communication technology for people with ALS will have significant consequences for their daily life, as well as for the clinical management of the disease, among others because of the potential interaction between the BCI and other procedures people with ALS undergo, such as tracheostomy. This article aims to facilitate responsible real-world implementation of implanted BCIs. We review the state of the art of research on implanted BCIs for communication, as well as the medical and ethical implications of the clinical application of this technology. We conclude that the contribution of all BCI stakeholders, including clinicians of the various ALS-related disciplines, will be needed to develop procedures for, and shape the process of, the responsible clinical application of implanted BCIs.
