A hospital wants to analyze smoking trends using patient-reported data. What is a major limitation?

1

שאלה #169135

		Smoking status may be misreported by patients.
		There is no way to verify smoking data.
		Smoking is not recorded in EHR systems.
		Both A and B

עישון דווקא כן מתועד ב-EHR, אך הנתונים מבוססים על דיווחי מטופלים, מה שעלול להיות לא מדויק.

Why is it important to consider the method of data collection when analyzing clinical data?

1

שאלה #169136

		Different methods may introduce measurement biases.
		Some methods are more accurate than others.
		The same measurement may be recorded differently across hospitals.
		All of the above.

הסיבות לכך: A) Different methods may introduce measurement biases – הטיות מדידה עלולות להיגרם משימוש בציוד רפואי שונה, אופן איסוף הנתונים (למשל, דיווח עצמי לעומת מדידה ישירה), או תנאי המדידה (כמו מדידת לחץ דם אחרי מאמץ לעומת במנוחה). B) Some methods are more accurate than others – שיטות שונות מספקות רמות שונות של דיוק. לדוגמה, בדיקות דם לנוכחות גלוקוז מדויקות יותר ממדידה באמצעות מד סוכר נייד. C) The same measurement may be recorded differently across hospitals – בתי חולים עשויים להשתמש בפרוטוקולים שונים לתיעוד מידע רפואי, מה שיכול להוביל לחוסר עקביות בנתונים. סיכום: השיטה שבה נאספים הנתונים משפיעה ישירות על הדיוק, האמינות והיכולת להשוות בין מחקרים ומוסדות רפואיים.
