More than four years after the COVID-19 pandemic upended our lives, you'd think things would be back to normal. But here's the shocking truth: diagnoses for depression and other chronic conditions are still lagging far behind what we'd expect. A groundbreaking study published in BMJ reveals that the pandemic's impact on healthcare may be far more lasting than we realized.
Researchers from King's College London analyzed electronic health records from England's National Health Service (NHS) OpenSAFELY network, tracking diagnosis rates for 19 long-term conditions from 2016 to 2024. They compared 2024 data with pre-pandemic trends and found a startling drop in diagnoses for several conditions.
The most alarming decline? Depression diagnoses are nearly one-third (27.7%) lower than expected. But it doesn’t stop there. Conditions like asthma (16.4% below), chronic obstructive pulmonary disease (COPD; 15.8% below), psoriasis (17.1% below), and osteoporosis (11.5% below) are also seeing fewer diagnoses.
So, what’s going on? The study’s authors point to a few key factors. Early in the pandemic, fear of infection kept many people away from medical facilities, delaying care for non-urgent conditions. Meanwhile, healthcare systems were overwhelmed, prioritizing COVID-19 over routine care.
And this is the part most people miss: the drop in depression diagnoses is most pronounced among young adults aged 20 to 39, particularly those of white or mixed ethnicity. Sam Norton, PhD, a co-author of the study, calls this trend “particularly striking and somewhat puzzling.” After a partial recovery in late 2021, diagnoses have plummeted since 2022.
But here’s where it gets controversial: does this mean fewer people are actually experiencing depression, or are cases simply going undiagnosed? The authors suggest the latter. They argue that pandemic-related pressures on healthcare—like the rise in remote consultations—may make it harder for doctors to spot the subtle, non-verbal signs of depression.
Another possibility? More people with depressive symptoms might be seeking help without receiving a formal diagnosis. Referrals to NHS talk therapy services have skyrocketed, with nearly 69% of referrals coming directly from individuals, bypassing doctors altogether.
This raises a critical question: Are we missing opportunities to diagnose and treat depression, or is the healthcare system adapting to new ways of delivering care? The authors call for further investigation, emphasizing the need to improve diagnostic capacity and ensure chronic conditions aren’t slipping through the cracks.
This study also highlights the power of large-scale, anonymized data to uncover trends and gaps in healthcare. By analyzing real-time data, we can better understand disease patterns, model workforce needs, and predict future demand. As Mark Russell, MD, PhD, and James Galloway, PhD, of King’s College London note, this approach could transform care delivery, ensuring resources are directed where they’re needed most.
But here’s the bigger question: What does this mean for the future of healthcare? Are we prepared to address the long-term consequences of the pandemic, or will these gaps persist? Let us know your thoughts in the comments—do you think the decline in diagnoses reflects a real drop in cases, or are we missing something crucial? The conversation starts here.
