Capital of Gram negative resistance Poor to absent infection control but burgeoning private healthcare industry with technological advances such as transplants Newer drugs available abroad take time to come What is available is often not affordable Irrational combinations abound due to poor regulatory control Antibiotic pipeline empty

Kumarasamy KK, Toleman MA, Walsh TR, et al. Emergence of a new antibiotic resistance mechanism in India, Pakistan, and the UK: a molecular, biological, and epidemiological study: ◦ 44 isolates with NDM-1 in Chennai, 26 in Haryana, 37 in the UK, and 73 in other sites in India and Pakistan. ◦ NDM-1 was mostly found among Escherichia coli (36) and Klebsiella pneumoniae (111) ◦ Highly resistant to all antibiotics except tigecycline & colistin ◦ Several of the UK source patients had undergone elective, including cosmetic, surgery while visiting India or Pakistan ◦ “We would strongly advise against such proposals…for UK patients to opt for corrective surgery in India” Lancet Infect Dis 2010;10:597-602
While other countries tackle the problem ◦ US FDA banned off label use of cephalosporins in cattle, swine, chickens, and turkeys effective 5 April 2012. ◦ Since April 2011, in Brazil the use of antimicrobials is no longer allowed without a prescription ◦ Israel implemented a nationwide plan to monitor and control carbapenemase resistant Enterobacteriaceae with an 80% reduction in rates (Clin Infect Dis 2011;52:848)
Our health ministry came out with an excellent document to prevent antimicrobial resistance in April 2011 Shelved it in October 2011!
OTC use banned for drugs in this category Warning boxes that advice against taking except in accordance with medical advice 91 drugs added including most antibiotics and anti-TB drugs May be pruned down to 20-25 drugs Will it be rationally decided? Will it be implemented?
What’s the MRSA rate here, I asked? ◦ What’s that Where’s the hospital antibiogram, I asked? ◦ Anti-what?

Antibiogram formulated for E.coli, Klebsiella, Staph aureus, Pseudomonas, Enterococcus Updated every 3 months Circulated to all clinicians Surveillance initiated Antibiogram ◦ VAP, CRBSI, CAUTI ◦ Rates of MDR-O monitored
Most Indian hospitals not constructed with plumbing at each bedside Greater the distance to basin, lazier we all get to hand wash! Microbiologically superior to hand washing unless hands visibly soiled Less skin damage than soap Have to have one per patient
Infectivity Prevention Perceived after stick threatHepatitis B 30% Vaccine LowHepatitis C 3% None NoneHIV 0.3% Post exposure High prophylaxis
Recombinant DNA vaccine given in 3 doses at 0, 1 & 6 mths Gluteal administration contra-indicated Successful vaccination indicated by antibody to HbsAg>10 mIU/ml
Consists of zidovudine 300 mg bd & lamivudine 150 mg bd for 4 weeks Second drug necessary only to cover the possibility of zidovudine resistance Of 18 documented failures of zidovudine, 8 involved source patients on zidovudine Usually not warranted for mucosal and intact skin exposures Start ASAP, definitely within 24 hrs
For patients with multi-resistant bacteria Consists of standard precautions plus unsterile gloves whenever patient is touched, then handwashing or hand rub immediately Plastic gowns if extensive patient contact Dedicated equipment eg stethoscope, BP apparatus and thermometer Sign at head of bed Single room or cohort nursing for MRSA One on one nursing essential
SARS in 2003 was when we introduced N-95 mask concept H1N1 in 2009 was a challenge ◦ Treated a large no of patients without a hospital outbreak ◦ Vaccination of employees introduced
Outbreak of XDR-TB in South Africa was mainly nosocomial Healthcare workers get active TB at rate of 5.8% annually in developing countries, well above general population Smear negative TB is also transmissible though 4 times less likely, accounts for 13% of all cases (Clin Infect Dis 2008;47:1135) MDR-TB 5-6 times more infectious than historical controls (PLoS Med 2008;5:e188) Three types of strategies: ◦ Administrative controls eg Mantoux for HCW ◦ Environmental controls ◦ Personal protection eg N-95 masks
Mechanical ventilation delivering negative pressure and 12 air changes per hour ◦ Costly, needs maintenance, may function poorly ◦ Needed for inpatient rooms, bronchoscopy Natural ventilation ◦ High ceilings, large windows, open doors & windows ◦ Can provide up to 40 air changes per hour ◦ Applicable to OP settings and HIV settings ◦ Fails in extreme climates when windows closed Upper room ultra-violet light ◦ Reduces airborne transmission by 70% ◦ Applicable to waiting room areas
Common, seen in 10-20% of patients ventilated for >48 hrs Intubation for mechanical ventilation increases the risk for pneumonia 3x to 21x !AJRCCM 2002; 165:867-903

Contamination rates in one study from 1974: ◦ bottle: 13% ◦ burette: 7% ◦ bag: 0.7% Switched to viaflex collapsible bags Avoided micro-infusion sets and vents Used infusion pumps instead Am J Hosp Pharmacy 1974;31:961
Use viaflex collapsible bags which do not need vents in preference to vented plastic or glass bottles Drops infection rate from 6.52 to 2.36 per 1000 line days West switched 30 years ago Am J Infect Control 2004;32:135
Clinical Culture based Outpatient follow-up Feedback Can reduce SSI rates by 35-50% Stratify monitoring to high risk group
Admission immediately pre-op Same day clipping instead of shaving Avoiding hypothermia Giving 1st dose antibiotic within 1 hr pre-incision Stopping antibiotics within 24 hrs
Prospective audit, intervention and feedback is the cornerstone Antibiotic forms introduced Special focus on surgical prophylaxis
Better implementation of antimicrobial stewardship Better adherence to hand hygiene regulations Checklist approach Need tighter regulatory control by authorities ◦ Antibiotics ◦ Hospital infection control programs ◦ Accreditation
