Ten-year national trends in in-hospital mortality and functional outcomes after intracerebral hemorrhage by age in Japan: J-ASPECT study.

ABSTRACT:

Introduction

National-level data on trends in the prognosis of age-stratified patients with intracerebral hemorrhage (ICH) are lacking. This study aimed to assess time trends in in-hospital mortality and functional outcomes of ICH patients by sex and age, and to explore factors associated with changes in in-hospital mortality trend.

Patients and methods

Using the largest nationwide, J-ASPECT stroke database in Japan, this serial cross-sectional study included ICH patients aged ⩾18 years who were hospitalized for non-traumatic ICH from April 2010 to March 2020. We examined trends in in-hospital mortality and functional outcomes using the modified Rankin Scale at discharge, as well as differences in in-hospital mortality change between age groups.

Results

Among 262,399 ICH patients from 934 hospitals, crude in-hospital mortality showed a significant decreasing time trend (from 19.5% to 16.7%), and this trend was consistent across sex and age groups. In addition, differences in in-hospital mortality change over the 10-year study period were significant between male patients aged ⩾75 years and those aged ⩽64 years (-3.9% [95% confidence interval, -5.4 to -2.4] for 75-84 years; -4.1% [-6.3 to -1.9] for ⩾85 years). On the other hand, the proportion of dependent patients (mRS 3-5) at discharge increased from 52.0% to 54.9% over the 10-year study period.

Conclusion

The in-hospital mortality of ICH patients improved, whereas the proportion of patients with dependent functional outcome at discharge increased, over the 10-year study period. Elucidating the mechanism underlying differences in in-hospital mortality reduction in men may provide insights into effective interventions in the future.

Project description:AimsDespite lithium's clinical efficacy, it is commonly thought that its use is declining. The objective of this study is to describe the new and prevalent lithium users as well as rates of discontinuation of lithium use over a 10-year period.MethodsThis study used provincial administrative health data from Alberta, Canada between January 1, 2009 and December 31, 2018. Lithium prescriptions were identified within the Pharmaceutical Information Network database. Total and subgroup specific frequencies of new and prevalent lithium use were determined over the 10-year study period. Lithium discontinuation was also estimated through survival analysis.ResultsBetween the calendar years of 2009 and 2018, 580,873 lithium prescriptions were dispensed in Alberta to 14,008 patients. The total number of new and prevalent lithium users appears to be decreasing over the 10-year timeframe, although the decline may have stopped or reversed in the latter years of the study period. Prevalent use of lithium was lowest among individuals between the ages of 18-24 years while the highest number of prevalent users were in the 50-64 age group, particularly among females. New lithium use was lowest amongst those 65 years and older. More than 60% (8,636) of patients prescribed lithium, discontinued use during the study timeframe. Lithium users between ages of 18-24 years were at the highest risk of discontinuations.ConclusionsRather than a general decline in prescribing, trends in lithium use are dependent on age and sex. Further, the period soon after lithium initiation appears to be a key time period in which many lithium trials are abandoned. Detailed studies using primary data collection are needed to confirm and further explore these findings. These population-based results not only confirm a decline in lithium use, but also suggest that this may have stopped or even reversed. Population-based data on discontinuation pinpoint the period soon after initiation as the time when trials are most often discontinued.
