Periodic Health Assessment/Screening - Key Features
1. Do a periodic health assessment in a proactive or opportunistic manner (i.e., address health maintenance even when patients present with unrelated concerns).
2. In any given patient, selectively adapt the periodic health examination to that patient’s specific circumstances (i.e., adhere to inclusion and exclusion criteria of each manoeuvre/intervention, such as the criteria for mammography and prostate-specific antigen [PSA] testing).
|General Population [by grade of evidence]||Specific Population|
|Discussion||Dental hygiene (fluoridation, brushing, flossing) [A]
Noise control and hearing protection
Seat belt use [B]
|Peds: developmental milestones [B] home visit for high risk family [A] |
Adolescents: counsel on sex and contraception [B], counsel to prevent smoking initiaton
|PE||Clinical breast exam (women 50-69) [B]: no longer recommended 2011
BP measurement [B]
|Peds: repeat hips, eyes, hearing (esp in first year) [A] |
Adults>65: Visual acuity [B]
1st Degree Relative with Melanoma: full body skin exam
|Tests||Colon cancer screening
||Not to screen > 74 yrs old unless specific indications|
|Tests||Women: mammography (50-74)q 2-3 yrs [A]
Pap smear: all girls > 9 yr should have HPV vaccines. 20 – 69 yrs, annually 3, every 2 yrs if normal x 3 yrs.
|Peds: hgb for high risk infants [B] |
Diabetics: fundsocopy [B]
TB high risk: mantouz skin test [A]
FAP: sigmoidoscopy and genetic testing [B]
|Therapy||Folic acid supplementation for women of child bearing age [A]
Varicella vax for children 1-12 [A]
|Peds: routine immunz [A] |
Hep B immuniz [A]
3. In a patient requesting a test (e.g., PSA testing, mammography) that may or may not be recommended:
a) Inform the patient about limitations of the screening test (i.e., sensitivity and specificity).
b) Counsel the patient about the implications of proceeding with the test.
PSA – sensitivity is ~80% & Specificity is ~70% at cut off of 4.0 (SN increased with higher cut off, serial testing and in conjunction with DRE)
Mammography – sensitivity 75-90% and specificity 90-95% over age of 50. Very high false positive rate in women under age 50. The NNS to prevent one death from breast cancer for women aged 40–49 years is 2108, as compared with 721 for women aged 50–69 years. In addition, the risk of a false-positive result from mammography is higher for women younger than 50 years. Thus, screening about 2100 women aged 40–49 years once every 2–3 years for about 11 years would prevent a single death from breast cancer, but it would also result in about 690 women having a false-positive result on a mammogram, leading to unnecessary follow-up testing, and 75 women having an unnecessary biopsy of their breast
Pap smear: False negative 10-40% for single test, false positive 5-10 %.
Stool occult blood: Sensitivity of FOBT has been shown to range from 12% (any neoplasia) to 36% (high grade neoplasia). The positive predictive value (probability that a person with a positive test has neoplasia) was 54% for any neoplasia, and 40% for advanced neoplasia; the negative predictive value (probability that a person with a negative test does not have neoplasia) was 64% and 88% respectively.
HPV: prevent up to 70% of cervical cancer
4. Keep up to date with new recommendations for the periodic health examination, and critically evaluate their usefulness and application to your practice.
