Corticosteroids Prescription Trends: One in Six Adults in England Prescribed in 2023, Major UK Study Reveals

Understanding the Landmark Study on Corticosteroids Prescriptions in England

A groundbreaking national study has illuminated the extensive use of corticosteroids among adults in England, revealing that more than one in six adults received at least one prescription in 2023. This research, published in The Lancet Regional Health – Europe, analyzed data from over 2.5 million patients across general practices, providing the most comprehensive snapshot to date of prescribing patterns for these potent anti-inflammatory medications. 0 108

Led by Dr. Hannah Whittaker from Imperial College London's School of Public Health, the study underscores corticosteroids' role as one of the most commonly dispensed drugs in primary care. With over 12 million unique prescriptions issued that year, it highlights both their indispensable therapeutic value and the imperative for judicious use to mitigate potential harms. 76

The investigation drew from the Clinical Practice Research Datalink (CPRD) Aurum database, covering approximately 20% of English general practices. This population-based cohort approach ensured robust, representative insights into real-world prescribing behaviors among adults aged 18 and older who were alive and registered during 2023.

What Are Corticosteroids and How Do They Work?

Corticosteroids, often simply called steroids, are synthetic drugs that mimic cortisol, a hormone naturally produced by the adrenal glands. Cortisol plays a crucial role in regulating metabolism, immune response, and stress. Medically, corticosteroids (full name: glucocorticoids and mineralocorticoids, though glucocorticoids predominate in prescriptions) powerfully suppress inflammation and modulate the immune system, making them vital for treating a spectrum of conditions from acute allergies to chronic autoimmune diseases.

They are administered via multiple routes: oral (e.g., prednisolone tablets), inhaled (e.g., beclometasone for asthma), topical (creams for eczema), nasal sprays (for rhinitis), and injectable forms. Each route targets specific issues while aiming to minimize systemic exposure and side effects. For instance, inhaled corticosteroids deliver medication directly to the lungs, reducing the dose needed compared to oral forms. 56

The process begins with diagnosis of an inflammatory condition. A general practitioner (GP) assesses symptoms, confirms via tests if needed, then prescribes the lowest effective dose for the shortest duration. Patients typically notice rapid relief—swelling reduces, pain eases—but must follow tapering protocols for longer courses to avoid withdrawal.

Key Prescription Statistics: Scale and Patterns

The study documented 12,029,952 unique corticosteroid prescriptions for 2,564,729 patients, equating to a median of two prescriptions per patient (interquartile range: 1–6). This prevalence—one in six adults—translates to roughly 17% of England's adult population encountering these drugs annually. 108

Inhaled forms dominated, reflecting their frontline role in managing chronic respiratory diseases. Oral corticosteroids, while fewer, raise concerns due to higher systemic risks. 76

Only 47.9% of patients had a clearly documented clinical indication in records up to two years prior. This gap signals opportunities for better documentation and stewardship.

Common Conditions Driving Prescriptions

Among those with recorded indications, asthma topped the list at 65.3%, followed by eczema (18.7%) and chronic obstructive pulmonary disease (COPD) at 18.0%. Respiratory and dermatological conditions often co-occurred, with 52.9% of multi-indication patients having both. 108

Other frequent uses include allergic rhinitis (nasal), rheumatoid arthritis or osteoarthritis (oral/joint injections), and acute exacerbations like flare-ups in inflammatory bowel disease. In England, where respiratory illnesses strain the NHS—especially post-COVID— these patterns align with national health burdens. For example, asthma affects about 5.4 million UK adults, per Asthma + Lung UK data.

• Asthma: Inhaled for maintenance, oral for exacerbations.
• Eczema: Topical for skin inflammation.
• COPD: Inhaled to prevent flares.

Demographic Insights: Who Receives Corticosteroids?

While full demographic breakdowns weren't detailed in summaries, patterns suggest higher use among older adults and women, common in chronic conditions like asthma and eczema. Deprivation indices (IMD) likely influence access and prevalence, with respiratory diseases more common in deprived areas. 97

In the UK context, England's aging population (over-65s projected to rise) amplifies demand. Women, comprising 60-70% of asthma patients, bear disproportionate burden. The study calls for targeted interventions in high-risk groups to optimize outcomes.

For those in academia or healthcare, exploring such disparities offers rich research jobs in pharmacoepidemiology at institutions like Imperial College London.

Associated Risks and Clinical Outcomes

Corticosteroids' benefits come with caveats. Short-term: minimal issues. Long-term (beyond weeks): osteoporosis, diabetes, hypertension, infections, cataracts, adrenal insufficiency. Oral forms pose highest risks; even low-dose chronic use elevates cardiovascular events. 64 57

The study notes associations with fractures, type 2 diabetes mellitus (T2DM), peptic ulcer disease (PUD), and infections, though causality requires further probing. NHS England recently issued guidance stressing monitoring for long-term users: bone density scans, glucose checks, gastric protection.NHS Monitoring Guidance

• Short-term risks: Mood changes, insomnia, appetite increase.
• Long-term risks: Osteoporosis (20-30% bone loss risk), immunosuppression (infection odds double).
• Mitigation: Lowest dose/shortest duration principle.

Historical Trends and Evolving Prescribing Practices

Corticosteroid use has risen over decades, driven by better asthma/COPD management. Inhaled prescriptions surged post-1990s guidelines; oral for asthma peaked then declined via stewardship. Pre-2023 data show 1.29 million annual oral courses for asthma alone. 12

2023 marks a baseline amid biologics rise (e.g., dupilumab for eczema). COVID-19 spiked respiratory steroids temporarily. Stewardship initiatives, like BTS/SIGN asthma guidelines, promote alternatives, reducing oral courses by 20-30% in pilots.

Stakeholder Perspectives: GPs, Patients, and Regulators

Dr. Whittaker emphasized: “Corticosteroids are important but overuse leads to side effects. This sets the scene for safer alternatives.” 76 GPs face pressures—quick relief demanded—but documentation lags. Patients report relief yet fear dependency; advocacy groups like Versus Arthritis push education.

NHS England prioritizes optimization; 2024/25 opportunities target high-risk meds. Multi-perspective: academics advocate data-driven guidelines, pharma innovates targeted therapies.

Implications for Public Health and Policy

High prevalence signals NHS burden: £100M+ annual spend, plus complications costing billions. Reducing unnecessary scripts—e.g., via biologics—could save lives/money. Regional variations (higher North England) highlight inequities.

Policy: Enhance e-prescribing audits, GP training. For UK higher education, this fuels pharmacovigilance research at unis like Manchester, Edinburgh.

Future Outlook: Stewardship, Alternatives, and Research

Prospects brighten with precision medicine. Biologics cut steroid need by 50-75% in severe asthma. AI-driven prediction models, from UK academics, promise personalized regimens.

Ongoing trials (e.g., STRATA for steroid tapering) and real-world evidence studies will refine practices. Horizon: 20% prescription drop by 2030 via stewardship. 48

Actionable Insights for Patients and Clinicians

Patients: Track doses, report side effects, ask about alternatives. Carry steroid card for long-term use.

Clinicians: Document indications, monitor per NHS protocols, consider deprescribing.

• Review every 3-6 months for chronic users.
• Prioritize non-drug therapies (e.g., lifestyle for COPD).
• Leverage apps for adherence tracking.
