Antibiotic Usage Guidelines in Hospital

Transcription

1 SUPPLEMENT TO JAPI december VOL Antibiotic Usage Guidelines in Hospital Camilla Rodrigues * Use of surveillance data information of Hospital antibiotic policy guidelines from Hinduja Hospital. The data presented includes only the top few isolated from the respective cultures at Hinduja Hospital and intends to represent at least 80 of the responsible for a given infection. The antibiotic susceptibilities are obtained as per available microbiology records, from Hinduja Hospital. Antibiotic with at least 80 cover for most common should be selected as empenic choice. Drug susceptibility is mentioned as based on data collected from January to August 2009, at Hinduja Hospital. Steps to Follow the Protocols Identify the type of infection bloodstream, respiratory, intra-abdominal or urinary tract, o Define the location ICU or floor patient o Accordingly refer the respective chart Identify the patient type based on described parameters Type 1, Type 2 or Type 3. Refer to the empiric column for that patient type. This will give you the protocol drug to start If a column has more than one drug option Choose the drug showing better susceptibility data in the left hand side table OR Doctor s discretion advised Send respective cultures before starting antibiotic Once culture / sensitivity report available: Presumptive antibiotic may require to be changed Consult Microbiology / ID physician to decide the choice of antibiotic (based on narrowest spectrum antibiotic which covers the pathogen isolated) In all cases physician s discretion is advised based on patient condition * Consultant Microbiologist, PD Hinduja Hospital, Mahim, Mumbai Hospital surveillance data (January-09 to August 09) Most common (n=124) 1 Klebsiella (n=44) 2 Escherichia coli (n=31) Blood Stream Infections - ICU Validity of these data: August- 35 Colistin (100) (96) (92) Amikacin (82) Pip-Taz/Cef- Sulb (75) 25 Colistin (100) Imipenem/ (91) /Amikacin (84 ) Pip - Taz /Cef- Sulb (71) 3 Pseudomonas 21 Colistin (100) aeruginosa (n=26) Imipenem (23) /Pip - Taz / Cef- Sulb / Amikacin (19) 4 Acinetobacter 11 Colistin (100) baumanii (n=14) Imipenem (43) Amikacin (36) 5 Enterobacter (n=9) 7 Colistin (100) / Pip-Taz / / Cef-Sulb /Amikacin (89) contact with health Contact with health Long hospitalization (e.g. last last with multiple within last exposure to group 2 carbapenems: Colistin - until culture report Consult Microbiology /ID Physician to decide on choice of
