Directive word: Describe
This question asks you to describe. The directive word signals the depth of analysis expected, the structure of your answer, and the weight of evidence you must bring.
See our UPSC directive words guide for a full breakdown of how to respond to each command word.
How this answer will be evaluated
Approach
The directive 'describe' demands comprehensive, structured exposition across all five sub-parts. Allocate approximately 40% of time/words to part (a) [20 marks], 30% to part (b) [15 marks], and 30% to part (c) [15 marks]. Structure as: (a) classification with examples, control sources, and comparative advantages; (b) definition, objectives, visit schedule (WHO/ICMR pattern), and balanced analysis of domiciliary services; (c) systematic differential for hematuria and evidence-based prostate cancer management. Use tabular formats for comparisons and flowcharts where applicable.
Key points expected
- (a)(i) Classification of epidemiological studies: observational (descriptive: case reports, cross-sectional; analytical: case-control, cohort, ecological) vs. experimental (RCT, field trials, community trials) with examples
- (a)(ii) Sources of controls in case-control studies: hospital/non-diseased patients, general population, relatives/friends, neighborhood controls, multiple control groups
- (a)(iii) Advantages of case-control over cohort: suitable for rare diseases, shorter duration, less expensive, smaller sample size, no attrition bias, multiple risk factors studied simultaneously
- (b) Antenatal care definition (WHO), objectives (screening high-risk, preventing complications, health education), schedule (minimum 4 visits: 12, 26, 32, 36 weeks or more frequent), domiciliary midwifery pros/cons (accessibility/cost vs. emergency backup limitations)
- (c)(i) Causes of hematuria in 60-year-old male: BPH, prostate carcinoma, urothelial malignancy, renal cell carcinoma, calculi, infection, glomerular disease, trauma, anticoagulation
- (c)(ii) Prostate carcinoma management: staging (TNM), active surveillance for low-risk, radical prostatectomy, radiotherapy (EBRT/ brachytherapy), androgen deprivation therapy, chemotherapy (docetaxel) for metastatic, follow-up with PSA
Evaluation rubric
| Dimension | Weight | Max marks | Excellent | Average | Poor |
|---|---|---|---|---|---|
| Concept correctness | 20% | 10 | Precise epidemiological terminology (incidence vs. prevalence, relative risk vs. odds ratio); accurate ANC schedule per WHO/ICMR guidelines; correct TNM staging for prostate cancer; distinguishes case-control from cohort study design without confusion | Generally correct definitions but minor errors in study design distinctions or ANC visit timing; vague on staging criteria | Fundamental confusion between study types (e.g., calling cohort prospective and case-control retrospective without nuance); incorrect ANC schedule; wrong staging system |
| Clinical correlation | 20% | 10 | Links hematuria in elderly male to malignant differentials first; contextualizes domiciliary midwifery within India's JSY/JSSK programs; cites Indian epidemiology (rising prostate cancer in urban registries); connects ANC to maternal mortality reduction | Mentions clinical relevance superficially; generic discussion without Indian public health context; lists differentials without prioritization by age | No clinical application; purely theoretical answers; misses malignant causes of hematuria in elderly; ignores national health program linkages |
| Diagram / pathway | 15% | 7.5 | Flowchart for epidemiological study classification; schematic of case-control design with arrows showing temporal direction; ANC visit timeline diagram; algorithm for hematuria evaluation in elderly male; prostate cancer management decision tree | One relevant diagram (typically study classification); poorly labeled or cramped; no temporal arrows in case-control schematic | No diagrams despite clear opportunities; text-only descriptions where visual representation would aid clarity |
| Differential / staging | 25% | 12.5 | Comprehensive hematuria differential prioritized by likelihood in 60-year-old male (malignancy > benign > medical causes); accurate TNM staging for prostate cancer (T1-T4, N, M); mentions Gleason score and risk stratification (low/intermediate/high) | Lists hematuria causes without age-specific prioritization; mentions staging but incomplete (e.g., only T stages); omits Gleason score | Incomplete differentials (misses urothelial/RCC); no staging mentioned; confuses BPH with prostate cancer management |
| Management / public-health angle | 20% | 10 | Evidence-based prostate cancer management with indications for each modality; balanced critique of domiciliary midwifery referencing Indian studies (e.g., Mumbai slum projects); mentions quality ANC components (tetanus, iron, detection of PIH/anemia); discusses referral linkages for high-risk pregnancies | Generic management without staging-based stratification; one-sided view of domiciliary care; routine ANC components listed without emphasizing high-risk detection | Outdated management (no active surveillance); no public health perspective; misses emergency obstetric care backup for domiciliary deliveries |
