Study Notes

Medicine and Evidence-Based Medicine

Medicine often lacks independence and transparency, which is a common issue in the field.
The Lancet published an article criticizing the promotion of statins for people aged 75 and older without cardiovascular disease, citing gaps in data and a lack of evidence for universal recommendation.

Statins and Cardiovascular Health

A review in 2021 found that statins have mild and rare adverse events, and a study found no link between statins and severe muscle pain.
The latest NICE guidance (Dec 2021) advises on lipid management for primary and secondary prevention of cardiovascular disease.

The Rise of Evidence-Based Medicine (EBM)

EBM involves using current best evidence in making decisions about individual patient care.
The concept emerged in the 1970s, recognizing that many clinical interventions had not been tested or evaluated.
Doctors relied on knowledge gained many years before at medical school.

Limitations of EBM

EBM approaches health from a universal, collective position, rather than considering individual patient needs.
Population-level evidence may not address individual context, such as co-morbidities, poly-pharmacy, and social situation.
Clinical judgment is necessary to balance population-level evidence.

Randomized Controlled Trials (RCTs) and EBM

RCTs are the "gold standard" of evidence-based medicine.
RCTs are designed for clinical and pharmacological interventions, but are challenging or impossible for social interventions.
As a result, the evidence base is distorted, favoring biomedical interventions over others (e.g., exercise).

Limitations of RCTs and EBM

RCTs are not suitable for evaluating community-based approaches to health, leading to a limited evidence base for such interventions.
Mistrust in the pharmaceutical sector can also limit the effectiveness of certain interventions.

Statins and Lay Perspectives

Patients may not always understand or appreciate the statistical risks and benefits of statins, leading to hesitation in taking the medication.
Different perspectives on health and risk can lead to disagreements between patients and doctors.

Points to Consider

Medical knowledge is not fixed or monolithic; different perspectives and assumptions are involved.
Understandings of health can be influenced by many factors, including evidence, industry, media, and values.
Drug dependency and the war on drugs have significant implications for health and social outcomes.
