Difficulty: Very hardPreventive Care and Screening

Evaluate the following patient encounters. Match each clinical vignette to the single most appropriate next best step in preventive care and screening.

  • A 64-year-old male with a 35 pack-year smoking history who quit 12 years ago. He has severe emphysema requiring home oxygen and heart failure with an ejection fraction of 25%. He presents for an annual wellness visit and asks about cancer screenings.Advise against low-dose computed tomography (LDCT) and routine colorectal cancer screening due to severe comorbidities limiting life expectancy and precluding curative interventions.
  • A 52-year-old female with chronic kidney disease (eGFR 22 mL/min) and type 2 diabetes. Her vaccination records show she received a single dose of the 23-valent pneumococcal polysaccharide vaccine (PPSV23) 4 years ago at age 48.Administer one dose of a high-valency pneumococcal conjugate vaccine (e.g., PCV20 or PCV21) today.
  • A 28-year-old female at 34 weeks gestation presenting in late October. She has a documented history of anaphylaxis to eggs. She received a Tdap vaccine 6 years ago and an updated COVID-19 vaccine 1 month ago.Administer the tetanus, diphtheria, and acellular pertussis (Tdap) vaccine, the maternal Respiratory Syncytial Virus (RSV) vaccine, and the inactivated influenza vaccine.
  • A 42-year-old asymptomatic male of Southeast Asian descent. He has a BMI of 23.5 kg/m² and a blood pressure of 126/80 mmHg. He exercises regularly and has no significant past medical history.Order a hemoglobin A1c or fasting plasma glucose to screen for abnormal blood glucose and type 2 diabetes.

Answer

Match the 64-year-old male to discontinuing cancer screenings, the 52-year-old female to the PCV20/PCV21 vaccine, the pregnant female to the Tdap/RSV/influenza vaccines, and the 42-year-old Asian male to diabetes screening.
Each specific clinical vignette features critical modifiers (comorbidities, race, pregnancy timing, prior vaccine types) that dictate a highly individualized application of USPSTF and ACIP guidelines.

Step-by-Step Solution

1
Evaluate the 64-year-old male's candidacy for LDCT and colorectal cancer screening.
Determine that he should not be screened.
Although he meets the age and pack-year criteria for LDCT, his severe emphysema and heart failure preclude curative lung surgery and limit his life expectancy to less than 10 years, which are direct USPSTF contraindications to continued screening.
2
Assess the pneumococcal vaccination needs of the 52-year-old female with CKD.
Determine that she requires a dose of PCV20 or PCV21.
ACIP guidelines recommend a high-valency conjugate vaccine (PCV20 or PCV21) for patients who have previously only received the polysaccharide vaccine (PPSV23), administered at least one year after the PPSV23 dose.
3
Determine the indicated obstetric vaccines for the 28-year-old at 34 weeks gestation in October.
Determine that she needs Tdap, RSV, and influenza vaccines.
Tdap is given in every pregnancy. The maternal RSV vaccine is administered between 32 and 36 weeks during RSV season. A history of egg anaphylaxis is not a contraindication to the influenza vaccine.
4
Analyze the diabetes screening criteria for the 42-year-old Asian American male.
Determine that a hemoglobin A1c or fasting glucose should be ordered.
Due to increased metabolic risks at lower body fat levels, the BMI threshold for diabetes screening in Asian Americans is 23 kg/m², which this patient meets.

Key Concept

Application of nuanced preventive care guidelines, including life-expectancy limits for cancer screening, sequence updates for adult pneumococcal vaccines, race-specific BMI thresholds for diabetes screening, and current obstetric vaccination protocols.
