Difficulty: HardHealthcare Economics and Value-Based Care

A 68-year-old man is evaluated in the general internal medicine clinic for preoperative clearance prior to an elective right eye phacoemulsification for cataracts. His past medical history is notable for essential hypertension and hyperlipidemia, both of which have been stable for several years. His current medications include amlodipine and atorvastatin. He reports feeling well and is physically active, swimming laps at the local pool three times a week. He denies dyspnea, orthopnea, chest pain, or palpitations. Vital signs are temperature 37.1°C (98.8°F), blood pressure 128/78 mm Hg, heart rate 68/min, and respiratory rate 14/min. Physical examination demonstrates clear lungs, normal heart sounds without murmurs, and no peripheral edema. The healthcare network has recently implemented a value-based care pathway aimed at reducing low-value clinical practices and minimizing unnecessary patient costs. In adherence to these high-value care principles, which of the following is the most appropriate next step in the preoperative evaluation of this patient?

  1. Recommend proceeding with the surgical procedure without additional diagnostic testingAnswer
  2. B
    Obtain a resting electrocardiogram to screen for silent myocardial ischemia given his age and comorbidities
  3. C
    Order a basic metabolic panel to verify normal renal function before the administration of perioperative medications
  4. D
    Obtain a posterior-anterior and lateral chest radiograph to ensure the absence of occult cardiopulmonary pathology
  5. E
    Postpone the procedure and refer the patient to cardiology for formal risk stratification

Answer

Recommend proceeding with the surgical procedure without additional diagnostic testing.
The correct approach is to recommend proceeding with the surgical procedure without additional diagnostic testing. This patient is undergoing cataract extraction, which is classified as a low-risk ambulatory surgery (associated with a <1% risk of major adverse cardiac events). In a patient with stable comorbidities and excellent functional capacity, routine preoperative testing such as electrocardiograms, chest radiographs, or laboratory studies does not improve surgical outcomes. Instead, it contributes to healthcare waste, increases out-of-pocket costs, and can lead to a cascade of unnecessary interventions due to false-positive results. This aligns closely with the Choosing Wisely campaign and value-based care initiatives.

Step-by-Step Solution

1
Assess the surgical risk of the planned procedure.
Cataract surgery is classified as a low-risk, ambulatory procedure.
The inherent risk of the surgery dictates the necessity and extent of preoperative testing.
2
Evaluate the patient's functional status and clinical stability.
The patient is asymptomatic, physically active (swims three times a week), and has stable, well-controlled comorbidities.
Active cardiac conditions or poor functional capacity (< 4 METs) might prompt targeted evaluation, but neither is present here.
3
Apply high-value care principles to preoperative testing.
Determine that routine laboratory testing, imaging, and EKGs are not indicated.
Choosing Wisely guidelines explicitly state that routine preoperative testing for low-risk surgeries does not improve outcomes and only adds unnecessary cost and potential harm from false positives.

Key Concept

High-value care dictates that routine preoperative diagnostic testing (ECG, laboratories, chest X-ray) should be avoided in asymptomatic patients undergoing low-risk ambulatory surgeries (e.g., cataract extraction), as it increases healthcare costs without improving patient safety.
