HALE BEST INDEX
Correct order of disease handicap disability impairment
Disease … impairment…. disability…. handicap
Handicap .. unable to perform social role
Pap smear, self breast exam which level of prevention
Secondary: early diagnosis and prevention
Validity vs Reliability
Validity is correct result, accuracy, efficiency
Reliability is consistency, precision, repeated result
Types of validity
Internal : for a sample
External: for population
Reliability 2 types
Intra rater : same person
Inter rater: 2 diff person

Nischay: upt kit
Nikshay : TB
Sensitivity vs specificity
Sensitivity is the ability of a test to detect who has the disease. P pVis ife a person is positive with a test, what’s the probability he has the disease.
ppv= SN×p/SN xp+ (1-Sp)(I-p) Baye’s Thosem
For a screening test, higher Sn is more important.
SN is more, Fp is more
What happens to SN and PPV in Test in
series and parallel.
In Series, Sn decrease and PPV Increase
and vice-versa
Biological wath Quality Standards.
In 100ml water, No sample Ecoli >3 coliforms.
not > 5% Sample throughout year Should have coliform
no 2 consecutive samples have any organism
