Methylxanthine use for acute asthma in the emergency department in Japan: a multicenter observational study.

ABSTRACT:

Aim

Methylxanthines are no longer recommended for emergency department (ED) patients with acute asthma according to international guidelines. We aimed to describe the current methylxanthine use for acute asthma and to determine factors related to its use in the ED.

Methods

We undertook a multicenter retrospective study in 23 EDs across Japan. From each participating hospital, we randomly identified 60 ED patients aged 18-54 years with acute asthma from 2009 through 2011. We examined the associations of ED and patient characteristics with methylxanthine use by constructing a multivariable logistic regression model adjusting for a predefined set of ED- and patient-level factors.

Results

Among 1,380 patients, methylxanthines were used for 79 patients (5.7%, 95% confidence interval [CI], 4.6-7.0%). The proportion of methylxanthine treatment varied substantially among EDs, ranging from 0% to 26.1%. In the multivariable analysis, the number of annual ED patients with acute asthma (odds ratio [OR] per 100 increase in annual asthma patients, 0.12; 95% CI, 0.04-0.34; P < 0.001) and having a protocol for asthma treatment (OR 2.91; 95% CI, 1.06-8.00; P = 0.04) at the ED level, and systemic corticosteroid use (OR 6.39; 95% CI, 3.34-12.22; P < 0.001) at the patient level were associated with likelihood of methylxanthine use.

Conclusions

In this multicenter study, approximately 6% of ED patients with acute asthma were treated with methylxanthines, with a wide variation across EDs. The number of annual ED patients with acute asthma was significantly associated with a lower likelihood of methylxanthine use, whereas having an ED asthma treatment protocol and systemic corticosteroid use in the ED were associated with a higher likelihood of methylxanthine treatment.

Project description:Adverse drug events are significant causes of emergency department visits. Systematic evaluation of adverse drug events leading to emergency department visits by age is lacking. This multicenter retrospective observational study evaluated the prevalence and features of adverse drug event-related emergency department visits across ages. We reviewed emergency department medical records obtained from three university hospitals between July 2014 and December 2014. The proportion of adverse drug events among total emergency department visits was calculated. The cause, severity, preventability, and causative drug(s) of each adverse drug event were analyzed and compared between age groups (children/adolescents [<18 years], adults [18-64 years], and the elderly [≥65 years]). Of 59,428 emergency department visits, 2,104 (3.5%) were adverse drug event-related. Adverse drug event-related emergency department visits were more likely to be female and older. Multivariate logistic regression analysis revealed that compared to non- adverse drug event-related cases, adverse drug event-related emergency department visitors were more likely to be female (60.6% vs. 53.6%, p<0.001, OR 1.285, 95% CI 1.025-1.603) and older (50.8 ± 24.6 years vs. 37.7 ± 24.4 years, p<0.001, OR 1.892, 95% CI: 1.397-2.297). Comorbidities such as diabetes, chronic kidney disease, chronic liver disease, and malignancies were also significantly associated with adverse drug event-related emergency department visits. Side effects were the most common type of adverse drug events across age groups, although main types differed substantially depending on age. Serious adverse drug events, hospitalizations, and adverse drug event-related deaths occurred more frequently in the elderly than in adults or children/adolescents. The proportion of adverse drug event-related emergency department visits that were preventable was 15.3%. Causative drugs of adverse drug events varied considerably depending on age group. Adverse drug event features differ substantially according to age group. The findings suggest that an age-specific approach should be adopted in the preventive strategies to reduce adverse drug events.

Project description:Low back pain accounts for nearly 4 million emergency department (ED) visits annually and is a significant source of disability. Physical therapy has been suggested as a potentially effective nonopioid treatment for low back pain; however, no studies to our knowledge have yet evaluated the emerging resource of ED-initiated physical therapy. The study objective was to compare patient-reported outcomes in patients receiving ED-initiated physical therapy and patients receiving usual care for acute low back pain. This was a prospective observational study of ED patients receiving either physical therapy or usual care for acute low back pain from May 1, 2018, to May 24, 2019, at a single academic ED (>91,000 annual visits). The primary outcome was pain-related functioning, assessed with Oswestry Disability Index (ODI) and Patient-Reported Outcomes Measurement Information System pain interference (PROMIS-PI) scores. The secondary outcome was use of high-risk medications (opioids, benzodiazepines, and skeletal muscle relaxants). Outcomes were compared over 3 months using adjusted linear mixed and generalized estimating equation models. For 101 participants (43 receiving ED-initiated physical therapy and 58 receiving usual care), the median age was 40.5 years and 59% were women. Baseline outcome scores in the ED-initiated physical therapy group were higher than those in the usual care group (ODI = 51.1 vs 36.0; PROMIS-PI = 67.6 vs 62.7). Patients receiving ED-initiated physical therapy had greater improvements in both ODI and PROMIS-PI scores at the 3-month follow-up (ODI = -14.4 [95% CI = -23.0 to -5.7]; PROMIS-PI = -5.1 [95% CI = -9.9 to -0.4]) and lower use of high-risk medications (odds ratio = 0.05 [95% CI = 0.01 to 0.58]). In this single-center observational study, ED-initiated physical therapy for acute low back pain was associated with improvements in functioning and lower use of high-risk medications compared with usual care; the causality of these relationships remains to be explored. ED-initiated physical therapy is a promising therapy for acute low back pain that may reduce reliance on high-risk medications while improving patient-reported outcomes. Emergency department-initiated physical therapy for low back pain was associated with greater improvement in functioning and lower use of high-risk medications over 3 months.
