Concept:
Clinical departments are directly involved in diagnosis, treatment, and patient care services.
Examples include:
• Outpatient Departments (OPD)
• Intensive Care Units (ICU)
• Specialty departments such as Orthopedics
The Medical Records Department is an administrative and supportive department responsible for maintaining patient records and documentation.
Step 1: Analyze option A.
General OPD provides outpatient medical consultation and treatment.
Hence, option A is a clinical department.
Step 2: Analyze option B.
Intensive Care Unit (ICU) provides critical patient care services.
Hence, option B is a clinical department.
Step 3: Analyze option C.
Orthopedic OPD manages patients with bone and joint disorders.
Hence, option C is a clinical department.
Step 4: Analyze option D.
Medical Records Department mainly handles storage, maintenance, and management of patient records and is not directly involved in patient treatment.
Hence, option D is not a clinical department.
Therefore, the correct answer is:
\[
\boxed{(D)\ \text{Medical Records Department}}
\]
