Study Room | Notes for Days When You Feel Lost in Clinical Practice

This is a room intended slightly more for healthcare professionals.

For medical students, residents, young doctors, and healthcare workers, I will be posting content that I felt I needed to organize during my daily clinical practice and studies.

The tone might be a bit different from the articles I write for the general public about health checkup results and physical signs.

However, the underlying sentiment remains the same.

To make knowledge usable in the field.

And to be able to see the person in front of me just a little bit better.

Creating the 'one book I really wanted' for clinical practice

Originally, I have been studying by creating my own 'one book I really wanted' for clinical practice, based on guidelines and textbooks.

Diabetes. Hypertension. Dyslipidemia. CKD. Heart failure. Osteoporosis. Obesity. Steroids. Connective tissue diseases.

Knowledge for all of these can be found by reading textbooks.

If you open the guidelines, the recommendations are also written there.

However, in actual outpatient clinics or wards, that is where one's hands might stop.

'What should I prioritize first for this patient?'

'What should I check before starting this medication?'

'I understand the numbers, but how should I act next?'

'How much should I organize before consulting a specialist?'

I would like to put into words and organize, as much as possible, those small hesitations that exist between textbooks and the clinical field.

What I will leave in this study room

On this page, I will organize articles for healthcare professionals and medical students by theme.

I plan to gradually compile paid articles, reference texts, clinical memos that can be read for free, and articles that can also be used for patient explanations.

This room is still under construction, but I will update this page as more articles are added.

Days when you feel lost in clinical practice.

Days when you have studied, but things still don't quite connect.

Days when you no longer know how to apply textbook knowledge to the patient in front of you.

I hope to make this a place you can return to on those days.

Themes I plan to add in the future

I plan to gradually grow this study room over time.

Moving forward, I will also organize themes such as the following:

・Diabetes
・Hypertension
・Dyslipidemia
・CKD
・Heart failure
・Osteoporosis
・Obesity
・Steroids
・Connective tissue diseases
・Symptom-based approach
・Medical English related to USMLE and OET

As the number of articles increases, I will add links to this page in order.

Finally

There is truly so much to memorize in medicine.

Disease names.

Laboratory values.

Drug names.

Guidelines.

Contraindications.

Dosage.

However, I believe the most difficult part of clinical practice is not knowing all of these things, but being able to apply them to the patient right in front of you.

From knowledge to judgment.

From judgment to action.

From action to the patient's daily life.

In this study room, I will gradually post articles that serve as a bridge for that process.

Notes I wish I could have handed to my younger self when I was a medical student.

Memos I wish I could have read on the days I felt lost as a resident.

I hope to stack up such things here.
