A recent investigation into the effects of prolonged use of inhaled corticosteroids (ICS) for chronic obstructive pulmonary disease (COPD) has uncovered significant health risks. The study, which analyzed electronic health records from over 20 million patients aged 45 and older, focused on comparing long-term users of ICS (more than two years) with short-term users (less than four months). Researchers discovered that extended ICS use significantly increases the likelihood of developing serious conditions such as type 2 diabetes, cataracts, pneumonia, osteoporosis, and nontraumatic fractures. This finding raises concerns about the widespread prescription of ICS for COPD patients who do not meet specific criteria.

The research involved creating two distinct patient groups: a prevalent cohort encompassing all individuals diagnosed with COPD at any point and an inception cohort comprising newly diagnosed patients. By employing propensity score matching, researchers identified that long-term users faced more than double the risk of experiencing one or more of the specified conditions compared to short-term users. Notably, among newly diagnosed COPD patients, one in five long-term ICS users developed at least one of these adverse outcomes.

In addition to overall risk assessments, the study also examined recurrent cases of certain conditions. For instance, individuals using ICS for extended periods were nearly three times more likely to experience repeated bouts of pneumonia. Furthermore, the likelihood of subsequent fractures was also elevated among this group. Each individual condition—diabetes, cataracts, pneumonia, osteoporosis, and fractures—was found to be more prevalent in long-term users even before being grouped into a composite outcome.

This research underscores the importance of carefully evaluating the necessity of prescribing ICS for COPD patients. Many patients receive these medications despite lacking indications that justify their use, thereby exposing themselves to unnecessary long-term health hazards.

These findings highlight the critical need for healthcare providers to reassess current practices regarding ICS prescriptions for COPD patients. By considering alternative treatments and ensuring that ICS is only prescribed when truly necessary, physicians can help mitigate the potential for severe health complications associated with its long-term use.
