PSM
freinds psm is a very important and special topic for FMGE.
every year around 25-30 questions asked from it. so based on my observation i m giving some high yielding topics and trends
1) formulaes- there are some formulaes u need to know like
*S.E(STANDARD ERROR)=(S.D or standard deviation/square root N) n= no of observation
*z score=observation-mean/S.D
*Odds ratio= TP x TN / FP x FN
*sensitivity= TP x 100 /TP+FN
*Positive Preditive Value = (TP/TP+FP) x 100
*Negative Predictive Value = (TN/TN+FN) x 100
*Variance = ( S.D.)2 = (S.D)square
*false negative[FN]=1-SENSITIVITY
*FALSE POSITIVE =1-SPECIFICITY
*percent prevalence = (TP+FN) x 100/(TP+FN+FP+TN)
*MEAN +- 1 S.D=68% OBSERVATIONS
*MEAN+- 2 S.D= 95% OBSERVATIONS
2)rates, ratio, propotions -
fundas should be cleared about them, their numerator, denominator(give emphasis on denominator for eg, wheter they are 1000 birth or 1000 live birth, mid year population etc etc) all will you get in your park text book . some importent one that frequently asked are
*incidence rate
*prevlance rate(although called as rate its a ratio)
*maternal mortality rate
*perinatal mortality rate
*infant mortality rate
*crude death rate
*standerized age specific rate
*neonatal mortality rate
*post neonatal mortality rate
*1-4 year mortality rate
*under 5 mortality rate
*pearl index(contraceptive failure measure)
*secondary attack rate
*SERIAL INTERVAL TIME
* incubation time
* generation time
* window period
again i m emphasising to concentrate on denominators of theses rates.
3) vector borne disease-
there is a list given in park textbook about disease their causitive agents and vector....every word of this list is importent so its better to cram it as early possible so that you will not overburdened in exam time and trust me in each and every exam at least 1 question has been asked .
4) EPIDEMIOLOGICAL STUDY -
this is one of favourate topic for NBE examiners. go with concept to actually understand the topic and also their merits and demerits. once u will get the core idea of a study designs you will eaisly solve these high scoring mcqs
most importent one are
*case control study
*cohart study
*descriptive study
*cross sectional study
*Longitudinal study
*odds ratio
*relative risk, attriuable risk
*varios bias in study like interview bias, confounding, berksonian bias
* blinding for removing bias
5) sensitivity, specificty,positive predictive value,negative predicitve value.
you should know about thier formulae as well as defination . a lot of exercises regarding it is given in mudit khanna book, so u can easily master it.and its also a importent topic regarding every competitive exam
6)vaccinations-
*EPI schedule and
*list of live vaccine and killed vaccine.
i made a formulae for that which i am putting
YETI MRP is 1 Billion
(yellow fever,epidemic typhus,typhoid oral vaccine,influnzae, MMR,polio-sabin,BCG ) rest all are killed vaccines .
SOME VACCINE ARE MORE IMPORTENT RGARDING DOSAGE, PREPARTION , COMPLICATIONS ,SITE, STRAIN ETC LIKE BCG, MEASLES, RABIES)
7)INFECTIOUS DISEASE- some disease in whole are importent like measles, T.B, LEPROSY ,yellow fever,chicken pox,pertusis ,tetanus
8)various type of rashes
9)wastes and mangement- this is the hot topic like color coding for various type of hospital waste, technique used, in park there given a table, no need to cram just hav a look on them is sufficient
10)contraception-( IUCD /OCP)this is the same topic you have read in obs and gynae, so concentrate hard on this as it can be asked in both psm and O &G.
11)HOUSING--
a newer topic which indicate change in pattern . since last 1,2 exams they are asking some criteria, no need to cram just have a look is sufficent.
12)NUTRITION -
kwashiorkar and marasmus are most important( can be asked from paediatrics too), beside that vitamins deficiency ,essential fatty acids, essential amino acids, oil rich in PUFA or saturated fats.(can be asked in medicine too) vitamin A DOSAGE are very importent
13)national eradication programms like malaria, leprosy, kala- azar- dont need to read everything but just know basics like their objective (deadlines asked frequently),high zone area etc- park is sufficient with latest issue.
14) nutrion surviellence - MUAC measurement, gomez classification,waterlow classification IAP , WHO classification.
15) ANTITUBERCULAR DRUGS, MALARIA TREATMENT AND PROPHYLAXIS, MDTleprosy, ANTIRETROVIRAL drugs , prophylaxis and preventive drugs for cholera, diphteria, meningitis, plague are imp(can be asked in medicine and pharmacology so reading thorougly give double advantage)
16) categories and regimen for DOTS is importent topic . you cant leave it.
17)ORS - compositin and also go to resomol, treatment plan for 3 types of dehydration categories (importent in paediatrics too)
18)types of data- QUALITATIVE/QUANTITATIVE.
BESIDE THAT NOMINAL/ORDINAL/ INTERVAL/RATIO. its easy trust, just try to understand it
19)mean , median , mode, range - concept should be cleared , its a very importent topic
20) normal curve graph and its properties.
21)demographic figures ;
a lot of question has been asked from it in september 2009. your park book is sufficient for that just have an idea of MMR, IMR, LITERACY RATE,POPULATION TRND, DEPENDENCY RATIO.
22) negative and positive skewed curves.
23)TESTS
*CHI SQUARE TEST
*PAIRED T TEST/UNPAIRED T TEST ( both are differnt and different indications)
*ANNOVA
*Z TEST
friends i hav a simple funda regarding that which i am posting
1. if data qualitative(means black/white, vaccinated/non vaccinated) mark chi square test as answer
2. if quantitative data( i.e can be measured like weight, B.P, height) mark t test. again if choice there is between pair and unpair then folllow as:
(A) paired t test for single group( for eg an effect of a drug on B.P a single group before tratment and after treament)
(B) unpaired t test ( if 2 groups r there for comparisons)
3.ANNOVA- (ANALYSIS OF VARIENCE) if more than 2 groups r there
just have a look on what are criteria for using these tests , means which type of study demands which tesr.
24)concept of primary health care(PHC) ,HEALTH SUNCENTRE, VILLAGE HEALTH GUIDE, ASHA is current hot topic these days.
you should know about staffing pattern of these units.
25) SAMPLING TECHNIQUES-types and meaning
especialy simple random versus clustering sampling
26) biological transmission i.e cyclodevlopmental, cyclopropogative, propogative (examples) are very importent.
27)what is screening, surviellence, case finding, monitoring
28)prevention level and their examples-
summarised as
1)primordial preventions- steps taken before appearing risk factors
2)primary prevention-risk factor present but iinhibiting appearence of disease
includes
a.health promotion (eg, life style modification,safe water,insect control)
b.specific protection ( eg vaccine, iron tablets)
3)secondary prevention( early diagnosis and treatment)
4)tertiary prevention- halt pathogenesis to limit impairment, rehabilitation
29)type-1 and type 2 errors
30)standard of living index
and human devlopment index
31)concepts of epidemic, endemic, pandemic.
32)mantoux test, lepromin test - u cant leave them
33) concept of isolation/quarantine ( both are not same)
34) refrence indian male and female chracterstics
35)management of pneumonia according to protocal( also asked in paediatrics)
36)some protein index
*biological value of protein
*net protein utilisation
*protein efficiency ratio
37) pasteurisation of milk- tests to ensure pasteurisation.
BOOKS RECOMMANDED
1)for those who are studying in 3,4 year having a plenty of time- go with park . give a read and then do side by side MCQ from any book like AAA OR SHARAT CHANDRA
2)THOSE WHO ARE GOING TO APPEAR : freinds u dont have time so go straightly with mudit khanna or AA AIIMS BOOK. by doing so you can easily solve problems.
3)question bank recommanded
A.)AAA- will cover about 80% of questions inexamination . so if u have a time u can do and can easily score in this high scoring subject
B.)SHARAT CHANDRA- is good but not as much diverse like AAA. but still one can opt for it as it have small explainations too ( demerit in AAA)
4)other options
(A)SARP SERIES FOR PSM is quite good and they also cover around 90 % of question but it is lengthy so suitable for that who just hate park text book and want to save time.
(B)PSM BY ARVIND ARORA gas been come which have questions of AAA with full explaination. suitable for those who have time and want to study subject in details
freinds i have tried my best to give these some most frequently asked topics about psm .hope this above information will help you in getting flying colours of sucess.
with my best wishes
