Common Conditions in Rural Hospitals - Age-Stratified Guide

1. NEONATES (0-28 Days)

Top Conditions

• Presentation: Fever or hypothermia, poor feeding, lethargy, high-pitched cry, bulging fontanelle, respiratory distress
• Organisms: Group B Streptococcus (early-onset, <48 hrs), E. coli, Klebsiella (late-onset)
• Management:
  • Blood culture before starting antibiotics (if lab available)
  • Early-onset: IV Ampicillin + Gentamicin for 7-10 days
  • Late-onset: IV Cefotaxime + Gentamicin (cover gram-negatives)
  • Supportive: warmth (KMC - Kangaroo Mother Care), IV fluids, oxygen if needed
  • Refer if not improving in 48 hours or if meningitis suspected (add CSF examination)

• Apgar score <7 at 1 or 5 minutes, failure to breathe at birth
• Management:
  • ABCD resuscitation: suction airway, tactile stimulation, bag-mask ventilation (21% O2 first)
  • If HR <60: chest compressions at 3:1 ratio with ventilation
  • Post-resuscitation: monitor glucose, seizures; if hypothermic encephalopathy - consider cooling if available
  • Refer to SNCU/NICU - rural hospitals should have basic stabilization capability

• Physiological jaundice: appears day 2-3, resolves by day 7 (term), day 14 (preterm)
• Pathological: appears <24 hours, rising bilirubin >5 mg/dL/day
• Management:
  • Phototherapy: double phototherapy for total serum bilirubin (TSB) above threshold for age (hour-specific Bhutani nomogram)
  • Exchange transfusion: TSB >20 mg/dL in term infant or clinical signs of kernicterus
  • Ensure adequate feeding (breastfeeding support)

• Kangaroo Mother Care (KMC) - skin-to-skin: reduces mortality by 40% in LBW neonates
• Exclusive breastfeeding
• Temperature maintenance: radiant warmer or KMC
• Vitamin K 1 mg IM at birth
• Surfactant if CPAP unavailable and gestational age <32 weeks (refer)

2. INFANTS AND CHILDREN (1 Month - 5 Years)

Top Conditions

• Viral pneumonia: supportive care, no antibiotics needed
• Avoid cough syrups in children <2 years
• Post-COVID note: Mycoplasma pneumoniae now more common in school-age children

• Causes: Rotavirus (most common in <5 yr), E. coli, Shigella, Vibrio cholerae (epidemics)
• Dehydration assessment is the key:

• Zinc supplementation: 10 mg/day for <6 months; 20 mg/day for >6 months x 14 days (reduces duration and recurrence)
• Antibiotics ONLY for: bloody diarrhea (Shigella - Ciprofloxacin/Azithromycin), cholera (Doxycycline), persistent diarrhea with positive giardia
• Continue breastfeeding throughout

• Plasmodium vivax: most common in India; causes regular tertian fever (every 48 hr)
• P. falciparum: life-threatening; cerebral malaria, blackwater fever, hypoglycemia, pulmonary edema

• Screen using MUAC: <115 mm = SAM; 115-125 mm = MAM
• Severe Acute Malnutrition (SAM) management (F-75 then F-100 protocol):
  • Phase 1 (Stabilization): F-75 formula, treat hypoglycemia, hypothermia, infection (IV Ampicillin + Gentamicin if severely ill)
  • Phase 2 (Rehabilitation): F-100 or RUTF (Ready-to-Use Therapeutic Food); Vitamins A, B-complex, folic acid, zinc, potassium
  • No iron in Phase 1 - worsens infection; start iron in Phase 2 only
  • Community-based management: RUTF (Plumpy'nut) can be given at home for uncomplicated SAM

• Measles: rash + fever + 3 Cs (cough, coryza, conjunctivitis); Vitamin A 200,000 IU x 2 doses; supportive
• Pertussis (whooping cough): paroxysmal cough + whoop; Azithromycin x 5 days (macrolide)

  • Treat concurrent deworming (Albendazole 400 mg biannual)
  • Dietary counseling: green leafy vegetables, jaggery, citrus for iron absorption

• Dysmenorrhea: NSAIDs (Ibuprofen 400 mg TDS) during periods; rule out PID/endometriosis in refractory cases
• Adolescent pregnancy: high-risk; refer for antenatal care, iron-folic acid, TT immunization
• RTI/STI screening in sexually active adolescents (often goes undetected in rural settings)

5. ADULTS (20-60 Years)

Communicable Diseases

• Symptoms: chronic productive cough >2 weeks, hemoptysis, fever, night sweats, weight loss, anorexia
• Diagnosis:
  • Sputum AFB smear (2 samples) - available at PHC

Non-Communicable Diseases (rising rapidly in rural adults)

• Diagnosis: BP >/= 140/90 on two separate visits (systolic/diastolic)
• Management:
  • Lifestyle: DASH diet, salt restriction (<5g/day), weight loss, exercise, stop smoking/alcohol
  • Stage 1 (140-159/90-99): lifestyle x 3 months, then pharmacotherapy if no response
  • Stage 2 (>/=160/100) or high CV risk: immediate pharmacotherapy
  • First-line drugs:
    • Amlodipine 5-10 mg/day (CCB) - most effective in South Asians
    • ACE inhibitor (Enalapril 5-20 mg/day) or ARB (Losartan 50-100 mg/day) - if diabetes/CKD
    • Hydrochlorothiazide 12.5-25 mg/day
  • Most patients need 2-3 drugs for control

• Screening: FPG >/=126 mg/dL, 2-hr PPG >/=200, HbA1c >/=6.5% (x2 tests or one if symptomatic)
• Management:
  • Lifestyle modification first

  • Add Glipizide/Glimepiride if HbA1c not at target (<7%) after 3 months
  • Insulin if HbA1c >10% or symptomatic hyperglycemia
  • Monitor: HbA1c every 3 months, BP, feet examination, urine albumin annually
  • Education: hypoglycemia recognition, foot care, diet

• Presentation: progressive dyspnea, chronic productive cough, barrel chest, reduced air entry, prolonged expiration
• Diagnosis: Spirometry (FEV1/FVC <0.70 post-bronchodilator) - confirm; clinical diagnosis often sufficient in rural settings
• Management by severity (GOLD stages):
  • All stages: smoking cessation, treat infections promptly, vaccines (flu, pneumococcal)
  • Mild (GOLD 1-2): SABA (Salbutamol inhaler 100 mcg, 2 puffs PRN) + LAMA (Tiotropium 18 mcg OD)
  • Moderate-severe: LABA + LAMA combination (Formoterol + Tiotropium)
  • Severe (FEV1 <30%): Add ICS (Budesonide) + oral theophylline; consider domiciliary O2
  • Acute exacerbation: Salbutamol nebulization, steroids (Prednisolone 40 mg x 5 days), antibiotics (Azithromycin or Amoxicillin-Clavulanate), O2 target SpO2 88-92%

6. ELDERLY (>60 Years)

• Be cautious: tight BP control <120/80 increases fall risk in frail elderly
• Target BP: <140/90 for most; <150/90 for frail/very elderly
• Watch for: orthostatic hypotension (measure lying and standing BP)
• Polypharmacy: review medications at every visit; deprescribe if needed

• Target HbA1c 7.5-8% (less strict due to hypoglycemia risk, fall risk)
• Avoid: sulfonylureas (risk of prolonged hypoglycemia), SGLT2 inhibitors if eGFR <30
• Metformin safe if eGFR >30

• Clinical: gradual painless visual loss, lens opacity on examination, reduced VA
• Management: surgical extraction (SICS/PHACO + IOL implant); refer to district hospital/eye camp
• Rural outreach eye camps are a key intervention

• Management: Paracetamol 500-1000 mg TDS (first-line analgesic); NSAIDs with caution (GI, renal risk); physiotherapy/exercise; avoid prolonged bed rest
• Topical Diclofenac gel for localized joint pain

• Screen with PHQ-2/PHQ-9 for depression
• Farmer suicides: a major rural crisis - mental health screening is part of your duty
• Management: Sertraline 25-50 mg/day (safest SSRI in rural settings); refer psychiatry if needed
• Dementia: MMSE screening; caregiver counseling; safety planning; refer

• Acute management: "Time is Brain" - <4.5 hours for thrombolysis (IV Alteplase 0.9 mg/kg, max 90 mg) if no contraindications; most rural hospitals cannot do CT immediately - refer FAST
• FAST screening: Face drooping, Arm weakness, Speech difficulty, Time to call
• Aspirin 300 mg loading dose in ischemic stroke (after hemorrhagic excluded by CT)
• Control BP, glucose, fever
• Secondary prevention: Aspirin 75-100 mg/day + Atorvastatin 40-80 mg/day + treat HTN

PRACTICAL TIPS FOR RURAL INTERNS

1. ABCDE assessment first - stabilize before diagnosis
2. ORS + Zinc is life-saving - keep liberal stock, teach mothers
3. Malaria RDT - quick diagnosis tool; use before starting antimalarials
4. DOTS supervisor - TB patients need observed therapy; do not prescribe and discharge
5. Fever workup in endemic areas - consider Malaria + Dengue + Scrub Typhus + Typhoid together (overlap in monsoon season)
6. Skin infections - commonest OPD condition; simple antifungals change lives
7. Antenatal care - do not miss high-risk pregnancies; iron-folic acid + TT + BP monitoring at every visit
8. Referral criteria - know when to refer: altered consciousness, refractory shock, severe respiratory distress, neonatal seizures, suspected surgical emergency
9. Vaccine history - ask at every visit; missed vaccines = preventable deaths
10. Document clearly - even simple case sheets save lives on referral

SEASONAL DISEASE PATTERN (Rural India)

Note: Drug dosages and protocols here reflect standard guidelines (WHO, IAP, NTEP). Always verify with your hospital formulary and consult a senior when in doubt. Rural medicine is as much about clinical judgment with limited resources as it is about textbook knowledge.This is a comprehensive guide built from authoritative sources including the Textbook of Family Medicine 9e, Park's Textbook of Preventive and Social Medicine, WHO IMCI guidelines, NTEP protocols, and current epidemiological data from rural India. Here's a summary of what's covered:

• Master ORS preparation and dehydration assessment - it saves children's lives daily
• The "undifferentiated fever" in monsoon season is almost always Malaria, Dengue, Scrub typhus, or Typhoid - test for all simultaneously
• Never send a TB patient home without enrolling them in DOTS
• Know your referral criteria - you cannot manage everything at a rural hospital, but you can stabilize and refer appropriately
