4.3 Preventive Care and Screening

Key Takeaways

  • Immunization schedules are published by the CDC and updated annually; medical assistants must know the routine childhood and adult vaccination schedules
  • Cancer screening recommendations include mammography (breast), colonoscopy (colorectal), Pap smear (cervical), and PSA/DRE (prostate) based on age and risk factors
  • Age-appropriate screenings include blood pressure, cholesterol, blood glucose, BMI, depression screening, and STI testing based on risk factors
  • The medical assistant's role in preventive care includes maintaining immunization records, reminding patients of due screenings, and providing patient education materials
  • Vaccines must be stored at proper temperatures (refrigerator 36-46°F; freezer -58 to 5°F) and documented with vaccine name, manufacturer, lot number, expiration date, site, route, and administrator

Preventive Care and Screening

Preventive care focuses on disease prevention and early detection rather than treatment of existing conditions. Medical assistants play a vital role in ensuring patients receive recommended screenings and vaccinations.


Immunization Schedule Highlights

Routine Childhood Vaccinations:

VaccineProtects AgainstSchedule
HepBHepatitis BBirth, 1-2 months, 6-18 months
DTaPDiphtheria, tetanus, pertussis2, 4, 6 months; 15-18 months; 4-6 years
IPVPolio2, 4 months; 6-18 months; 4-6 years
HibHaemophilus influenzae type b2, 4, 6 months; 12-15 months
PCV13Pneumococcal disease2, 4, 6 months; 12-15 months
MMRMeasles, mumps, rubella12-15 months; 4-6 years
VaricellaChickenpox12-15 months; 4-6 years
HPVHuman papillomavirus11-12 years (2-3 dose series)
TdapTetanus, diphtheria, pertussis (booster)11-12 years
MenACWYMeningococcal disease11-12 years; booster at 16

Routine Adult Vaccinations:

VaccineRecommendation
InfluenzaAnnually for all adults
Td/TdapTdap once, then Td booster every 10 years
Shingles (RZV)Age 50+ (2-dose series)
Pneumococcal (PCV20/PPSV23)Age 65+ or high-risk adults
COVID-19Per current CDC recommendations
HPVUp to age 26 (catch-up to age 45 for some)

Vaccine Storage Requirements:

  • Refrigerator vaccines (most): 36-46°F (2-8°C)
  • Freezer vaccines (varicella, MMR, some COVID): -58 to 5°F (-50 to -15°C)
  • Monitor temperatures twice daily and record in a temperature log
  • Use calibrated thermometers in all storage units
  • Never store vaccines in the door of the refrigerator (temperature fluctuates)
  • If temperature excursion occurs, do NOT use vaccines until consulting the manufacturer

Cancer Screening Recommendations

CancerScreening TestStarting AgeFrequency
BreastMammography40-50 (varies by guideline)Every 1-2 years
CervicalPap smear ± HPV testAge 21Every 3 years (Pap alone) or 5 years (Pap + HPV)
ColorectalColonoscopy, FIT, stool DNAAge 45Colonoscopy every 10 years; FIT annually
ProstatePSA ± DREAge 50 (earlier for high-risk)Shared decision-making with provider
LungLow-dose CT scanAge 50-80 with 20+ pack-year smoking historyAnnual

Vaccine Administration Documentation

Every vaccine administration must be documented with:

  • Patient name and date of birth
  • Vaccine name and manufacturer
  • Lot number and expiration date
  • VIS (Vaccine Information Statement) date and date given to patient
  • Dose and route of administration
  • Injection site (right deltoid, left thigh, etc.)
  • Name, title, and signature of the person administering the vaccine
  • Date and time of administration

The Vaccine Information Statement (VIS) is a CDC-produced document that must be given to the patient (or parent/guardian) before each vaccination. It explains the benefits and risks of the vaccine.
