Methamphetamine use association with pulmonary diseases: a retrospective investigation of hospital discharges in California from 2005 to 2011

Abstract

BackgroundMethamphetamine can have acute and long-term adverse health consequences. Our objective was to determine whether methamphetamine use is associated with more hospitalisation codes for asthma exacerbation, chronic obstructive pulmonary disease (COPD) exacerbation, pneumonia and acute respiratory failure (ARF).MethodsThe Health Care Utilization Project (HCUP) database includes retrospective inpatient discharge abstracts from 2005 through 2011 from the California state inpatient databases (SIDs). ICD-9 codes were used to identify hospitalisations for asthma exacerbation, COPD exacerbation, acute pneumonia, ARF and methamphetamine use from discharges with complete demographic data and ages 18 to 75 years. Adjusted rate ratios comparing methamphetamine users with nonusers were estimated separately for each pulmonary disease diagnosis by sex using negative binomial regression models.ResultsWe included 21 125 249 inpatient discharges from 2005 through 2011 in California in our analysis; 182 766 (0.87%) had methamphetamine use. The rate ratio comparing pneumonia in discharges with methamphetamine use versus those without were 1.40 (95% CI 1.18, 1.67) for women and 1.18 (95% CI 1.04, 1.35) for men; comparing ARF 1.77 (95% CI 1.59, 1.98) for women and 1.24 (95% CI 1.12, 1.37) for men; and comparing COPD exacerbation 1.40 (95% CI 1.18, 1.67) for women and 0.90 (95% CI 0.79, 1.02) for men.ConclusionsA positive association was found when comparing inpatient hospital discharge diagnoses for methamphetamine use and those for pneumonia and ARF in both sexes. This association was not seen when comparing discharge diagnoses for methamphetamine and those for asthma exacerbation in both sexes or COPD exacerbation in men. While future investigation for is warranted, this finding may help to further characterise the pulmonary toxicity of methamphetamine.

Methamphetamine deaths: Changing trends and diagnostic issues

“…55 Tsai et al. 56 concluded that there are higher rates of pneumonia and acute respiratory failure in both men and women who abuse methamphetamine, whereas acute exacerbations of chronic obstructive pulmonary disease occurred more often in women. There was no link found between methamphetamine use and acute asthma.…”

Why METH users are at high risk of fatality due to COVID-19 infection?

“…All of these may increase their vulnerability to COVID-19 infection [3][4][5]. Regular administration of METH is associated with various neurological symptoms such as anxiety, depression, psychosis, psychiatric impairment [6], cardiac [7], respiratory complications [8], and overall decreased immune health. METH users group, is much stigmatized and marginalized, and tend to remain well hidden in large population groups.…”
