Cost-effectiveness Analysis Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Cost-effectiveness Analysis. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Cost-effectiveness Analysis Indian Medical PG Question 1: What surgery is shown here in the image?
- A. Hemorrhoidectomy
- B. Altemeier operation
- C. Wells procedure
- D. Thiersch wiring (Correct Answer)
Cost-effectiveness Analysis Explanation: ***Thiersch wiring***
- The image clearly depicts a **suture or wire** placed circumferentially around the anus to reduce its caliber, which is the hallmark of a **Thiersch procedure**.
- This technique is used to treat **anal incontinence** by constricting the anal opening and improving sphincter function.
*Hemorrhoidectomy*
- This procedure involves the **surgical removal of hemorrhoids** and the images do not show any identifiable hemorrhoidal tissue being excised.
- While bleeding and prolapse can be associated with hemorrhoids, the depicted technique with circumferential wiring is not used for their removal.
*Altemeier operation*
- The Altemeier operation is a type of **perineal rectosigmoidectomy** for rectal prolapse that involves resecting the prolapsed segment of the rectum.
- The image does not illustrate resection of rectal tissue; instead, it shows a constricting device around the anus.
*Wells procedure*
- The Wells procedure, or **rectopexy**, involves anchoring the rectum to the sacrum to correct rectal prolapse.
- This procedure typically involves an abdominal approach and fixation techniques, which are not represented in the illustration.
Cost-effectiveness Analysis Indian Medical PG Question 2: Based on healthcare utility values and life expectancy, which of the following measures can be calculated? Consider a scenario where the average life expectancy for a woman in Japan is 87 years, and there is an increase in life expectancy due to healthcare advancements.
- A. HALE
- B. DALY
- C. DFLE
- D. QALY (Correct Answer)
Cost-effectiveness Analysis Explanation: ***QALY***
- **Quality-Adjusted Life Years (QALYs)** combine the length of life with the **quality of life** lived, taking into account healthcare utility values (e.g., from 0 for dead to 1 for perfect health).
- An increase in life expectancy due to healthcare advancements, coupled with assumed utility values, directly enables the calculation of QALYs gained or lost.
*HALE*
- **Health-Adjusted Life Expectancy (HALE)** is a measure of the average number of years that a person can expect to live in "**full health**" by adjusting for years lived in less than full health due to disease or injury.
- While it incorporates health status, it specifically focuses on time lived in full health rather than the utility-weighted quality of life over the entire lifespan as QALYs do.
*DALY*
- **Disability-Adjusted Life Years (DALYs)** measure the total number of healthy years lost due to disease, disability, or premature death.
- DALYs are a measure of disease burden, quantifying years lost, whereas QALYs are a measure of health gains or health states.
*DFLE*
- **Disability-Free Life Expectancy (DFLE)** measures the expected number of years an individual will live without disability.
- While it considers the absence of disability, it does not incorporate the concept of "utility values" or varying degrees of health-related quality of life beyond a binary disabled/non-disabled state, as QALYs do.
Cost-effectiveness Analysis Indian Medical PG Question 3: Which of the following is not a component of the Thoracoscore?
- A. Surgery priorities
- B. ASA classifications
- C. Expected complications post-surgery (Correct Answer)
- D. Performance status
Cost-effectiveness Analysis Explanation: ***Expected complications post-surgery***
- While patient risk assessment tools aim to predict surgical outcomes, the **Thoracoscore** specifically calculates risk based on present patient characteristics and surgical plan, not based on a list of expected complications.
- Expected complications are a *result* of the risk score, not an input into its calculation.
*ASA classifications*
- The **American Society of Anesthesiologists (ASA) Physical Status Classification System** is a crucial component of the Thoracoscore, reflecting the patient's overall health status and comorbidity burden.
- A higher ASA classification indicates greater surgical risk and contributes to the Thoracoscore calculation.
*Surgery priorities*
- **Surgery priority** (e.g., elective, urgent, emergency) is an important factor in the Thoracoscore, as urgent or emergent surgeries are associated with higher risk.
- This parameter helps categorize the immediacy and complexity of the surgical intervention.
*Performance status*
- The patient's **performance status**, often assessed using scales like the Eastern Cooperative Oncology Group (ECOG) or Karnofsky, is a significant predictor of surgical outcome and is included in the Thoracoscore.
- A lower performance status (indicating poorer functional capacity) increases the calculated surgical risk.
Cost-effectiveness Analysis Indian Medical PG Question 4: IOC for Acute Aortic Dissection in a Clinically Unstable patient is?
- A. NCCT
- B. TEE (Correct Answer)
- C. MRI
- D. CT-Angio
Cost-effectiveness Analysis Explanation: ***TEE (Transesophageal Echocardiography)***
- **TEE is the investigation of choice** for acute aortic dissection in **hemodynamically unstable patients** due to its **portability and rapidity**.
- Can be performed at the **bedside** without transporting the critically ill patient, minimizing risk.
- Provides rapid diagnosis (5-10 minutes) with **>95% sensitivity and specificity** for detecting intimal flap and false lumen.
- Simultaneously assesses **complications** such as aortic regurgitation, pericardial effusion/tamponade, and ventricular function.
- Particularly excellent for visualizing the **ascending aorta** and aortic root.
*CT-Angio*
- **CT angiography** is the **investigation of choice** for acute aortic dissection in **hemodynamically STABLE patients**.
- Provides excellent anatomical detail of the entire aorta, clearly showing the intimal flap, true and false lumens, and branch vessel involvement.
- Requires **patient transport** to the radiology department, which is **unsafe in unstable patients**.
- Best for comprehensive surgical planning in stable patients.
*MRI*
- **MRI** offers the highest anatomical detail and is considered the gold standard for **chronic dissection follow-up**.
- Its lengthy acquisition time (30-60 minutes) and incompatibility with monitoring equipment make it **unsuitable for acutely unstable patients**.
*NCCT*
- **Non-contrast CT** may show indirect signs like the **hyperdense crescent sign** in the aortic wall.
- Cannot reliably differentiate true and false lumens or assess the full extent of dissection.
- Insufficient for definitive diagnosis or management planning.
Cost-effectiveness Analysis Indian Medical PG Question 5: What is the condition commonly known as jumper's knee?
- A. Inflammation of the patellar tendon at its insertion on the patella.
- B. Tendinopathy of the quadriceps tendon.
- C. Injury to the hamstring tendon.
- D. Patellar tendonitis due to overuse of the patellar tendon. (Correct Answer)
Cost-effectiveness Analysis Explanation: ***Patellar tendonitis due to overuse of the patellar tendon.***
- **Jumper's knee** is the common term for **patellar tendonitis**, which specifically refers to inflammation of the patellar tendon.
- This condition is frequently caused by **overuse**, especially in activities involving repetitive jumping and landing.
*Inflammation of the patellar tendon at its insertion on the patella.*
- While jumper's knee does involve inflammation of the patellar tendon, it is more commonly at its insertion on the **tibial tubercle** or specifically its origin at the **inferior pole of the patella**, not necessarily at the patella itself.
- This option is less precise as it describes only one aspect of the condition without mentioning the critical role of overuse.
*Tendinopathy of the quadriceps tendon.*
- **Tendinopathy of the quadriceps tendon** is a distinct condition affecting the tendon above the patella, known as **quadriceps tendinopathy**.
- It presents with pain proximal to the patella, differentiating it from jumper's knee, which involves the tendon distal to the patella.
*Injury to the hamstring tendon.*
- An **injury to the hamstring tendon** would cause pain and symptoms on the posterior aspect of the knee or thigh.
- This is completely unrelated to jumper's knee, which is characterized by anterior knee pain.
Cost-effectiveness Analysis Indian Medical PG Question 6: Most cost effective approach for the prevention of non-communicable disease is by -
- A. Primary prevention
- B. Specific protection
- C. Secondary prevention
- D. Primordial prevention (Correct Answer)
Cost-effectiveness Analysis Explanation: ***Primordial prevention***
- This level of prevention targets the **root causes** of risk factors, preventing their emergence in the first place through societal-level interventions.
- By shaping healthy environments and promoting healthy lifestyles from birth, it can avert the development of NCDs across entire populations, making it the **most cost-effective** long-term strategy.
*Primary prevention*
- This involves preventing the onset of disease in healthy individuals by controlling existing risk factors through measures like **vaccination** and health education.
- While effective, it addresses risk factors once they exist, which is less cost-effective than preventing their initial emergence through primordial approaches.
*Specific protection*
- This is a subset of **primary prevention** focused on specific measures to protect against disease, such as immunizations or wearing protective gear.
- It's effective for targeted diseases but does not address the broader societal determinants of health as comprehensively as primordial prevention.
*Secondary prevention*
- This aims to **detect and treat diseases early** to prevent complications and progression, such as through screening programs and early treatment.
- While crucial for improving outcomes once a disease has begun, it is inherently more costly than preventing the disease from ever occurring.
Cost-effectiveness Analysis Indian Medical PG Question 7: Which of the following procedures is not typically covered by the National Programme for Control of Blindness (NPCB) for reimbursement of surgery done by a non-governmental organization (NGO) eye hospital?
- A. Cataract surgery
- B. Pan retinal photocoagulation for diabetic retinopathy
- C. Syringing and probing of the nasolacrimal duct (Correct Answer)
- D. Trabeculectomy surgery
Cost-effectiveness Analysis Explanation: ***Syringing and probing of the nasolacrimal duct***
- While important for lacrimal drainage issues, procedures like **syringing and probing** are generally considered minor and less vision-restoring compared to the major surgeries targeted by the **NPCB**.
- The **NPCB** focuses on interventions for leading causes of blindness, primarily **cataract** and other significant vision-threatening conditions, which this procedure typically isn't.
*Cataract surgery*
- **Cataract surgery** is a cornerstone of the **NPCB's** efforts, as cataracts are the leading cause of reversible blindness.
- Reimbursement for **cataract surgery** is a primary objective to improve access and reduce the burden of blindness.
*Pan retinal photocoagulation for diabetic retinopathy*
- **Diabetic retinopathy** is a major cause of preventable blindness, and **pan retinal photocoagulation (PRP)** is a key intervention to preserve vision.
- The **NPCB** includes procedures for **diabetic retinopathy** management due to its significant public health impact.
*Trabeculectomy surgery*
- **Trabeculectomy** is a surgical procedure for **glaucoma**, which is another significant cause of irreversible blindness.
- The **NPCB** includes interventions for **glaucoma** given its severe vision-threatening nature and the need for surgical management in many cases.
Cost-effectiveness Analysis Indian Medical PG Question 8: A 65-year-old lady presented with a swollen and painful knee. On examination, she was found to have grade III osteoarthritic changes. What is the best course of action?
- A. Conservative management
- B. Total knee replacement (Correct Answer)
- C. Arthroscopic washing
- D. Partial knee replacement
Cost-effectiveness Analysis Explanation: ***Total knee replacement***
- For **grade III osteoarthritis** in a 65-year-old, a total knee replacement is the most definitive and effective treatment to relieve pain and restore function in a severely damaged joint.
- This procedure addresses widespread cartilage loss and structural changes typical of advanced osteoarthritis.
*Conservative management*
- This approach is typically favored for **mild to moderate osteoarthritis**, involving physical therapy, NSAIDs, and lifestyle modifications.
- For **grade III changes** with significant pain and swelling, conservative measures are unlikely to provide sufficient relief or halt disease progression effectively.
*Arthroscopic washing*
- **Arthroscopic lavage** and debridement are rarely recommended for osteoarthritis as they have not shown sustained benefits for pain or function.
- It is sometimes used for specific mechanical symptoms, but it does not address the underlying cartilage loss and structural damage in severe osteoarthritis.
*Partial knee replacement*
- A **partial knee replacement** is suitable when osteoarthritis is confined to a single compartment of the knee, and the other compartments are healthy.
- Given the indication of "grade III osteoarthritic changes" without specifying a single compartment, a total knee replacement is generally more appropriate for widespread disease.
Cost-effectiveness Analysis Indian Medical PG Question 9: A 55-year-old male, known smoker, complains of calf pain while walking. He experiences calf pain while walking but can continue walking with effort. Which grade of claudication does this patient fall under?
- A. Grade I (Mild claudication)
- B. Grade II (Moderate claudication) (Correct Answer)
- C. Grade III (Severe claudication)
- D. Grade IV (Ischemic rest pain)
Cost-effectiveness Analysis Explanation: ***Grade II (Moderate claudication)***
- **Grade II claudication** is characterized by **intermittent claudication** where the patient experiences pain while walking but can **continue walking with effort**.
- This level of claudication reflects a moderate degree of peripheral arterial disease, where blood flow is sufficiently compromised to cause pain with exertion but not severe enough to force immediate cessation of activity.
- The patient in this scenario can continue ambulation despite discomfort, which is the defining feature of this grade.
*Grade I (Mild claudication)*
- **Grade I claudication** involves discomfort or pain that the patient can **tolerate without significantly altering their gait or pace**.
- In this stage, the pain is minimal, and the patient may perceive it as a dull ache or mild fatigue rather than true pain.
- Walking can continue without significant effort or limitation.
*Grade III (Severe claudication)*
- **Grade III claudication** is marked by pain that is **severe enough to stop the patient from walking within a short distance** (typically less than 200 meters).
- The pain forces the patient to rest and recover before they can resume walking.
- This represents significant functional limitation in daily activities.
*Grade IV (Ischemic rest pain)*
- **Grade IV**, also known as **critical limb ischemia**, involves **pain even at rest**, especially in the feet or toes, often worsening at night when the limb is elevated.
- This stage indicates severe arterial obstruction and is frequently associated with **ulcers, non-healing wounds, or gangrene**.
- This represents advanced peripheral arterial disease requiring urgent intervention.
**Note:** This grading system is a simplified clinical classification. The standard medical classifications for peripheral arterial disease are the **Fontaine classification** (Stages I-IV) and **Rutherford classification** (Categories 0-6).
Cost-effectiveness Analysis Indian Medical PG Question 10: In which of the following surgeries is monopolar cautery preferred over bipolar cautery?
- A. Surgery around Penis
- B. Surgery of the Hip (Correct Answer)
- C. Hand Surgery
- D. Surgery around the face
Cost-effectiveness Analysis Explanation: ***Surgery of the Hip***
- **Monopolar cautery** is preferred in surgeries like hip surgery where a larger area needs to be coagulated, as it provides a wider field of effect and can be more efficient for **deep tissue coagulation**.
- Its mechanism relies on the current passing through the patient to a large **dispersive electrode (grounding pad)**, making it suitable for extensive tissue work.
*Hand Surgery*
- In **hand surgery**, delicate structures like nerves and tendons are abundant, making **bipolar cautery** safer due to its localized current flow and reduced risk of inadvertent thermal spread.
- **Bipolar cautery** limits the current to a small area between the two prongs of the instrument, thus minimizing damage to surrounding tissues.
*Surgery around Penis*
- **Bipolar cautery** is generally preferred in sensitive areas like the penis, due to its localized effect and reduced risk of thermal injury to adjacent delicate structures.
- The avoidance of current passing through the body to a grounding pad in **bipolar modality** is especially important in areas with potential for nerve damage or scarring.
*Surgery around the face*
- Surgically around the face often involves delicate tissues and structures where **bipolar cautery** is favored to prevent widespread thermal damage and minimize scarring or nerve injury.
- The confined current path of **bipolar cautery** makes it ideal for precision work in cosmetic or reconstructive facial surgery.
