H1N1

This study is ending as of July 2.

Researchers for Dr. Kumar are now collecting data more detailed than ours about H1N1, so we will discontinue collecting tmp data on these patients. Keep what data you have collected and send it, but don't collect any more. Ttenbergen 13:37, 2 July 2009 (CDT)

Definitions and coding information

H1N1 SUSPECTED

• H1N1 suspected patients that are admitted with DX of severe respiratory CAP and/or COPD
  • treatment with antiviral drugs (E.G. oseltamivir (Tamiflu®), zanamivir (Relenza®) and amantadine) makes the patient a suspect regardless of the isolation status.
  • swabbed & isolated- then the patient is a suspect
  • the date the swab was ordered is the "suspect date" to put in the TMP file (time is not required)
  • the date the unit is notified that the swab was positive is the confirmed date to put in the TMP file (time is not required)
  • code the patient CAP 75 - Influenza virus "
  • the date the unit is notified the swab was negative is the "negative date" to put in the TMP file (time is not required)
  • leave the suspect date in the TMP file even if the swab in negative.
  • If the patient is discharged or death occurs prior to the swab results then code CAP-unknown pathogen
  • Suspect and confirmed dates remain the same if patients move to different units.

• H1N1 suspected patients that are admitted with DX of severe flu without CAP - [[Disseminated Infection]
  • treatment with antiviral drugs (E.G. oseltamivir (Tamiflu®), zanamivir (Relenza®) and amantadine) makes the patient a suspect regardless of the isolation status.
  • swabbed & isolated- then the patient is a suspect
  • the date the swab was ordered is the "suspect date" to put in the TMP file (time is not required)
  • the date the unit is notified that the swab was positive is confirmed is the "confirmed date" to put in the TMP file (time is not required)
  • code the patient [[Disseminated Infection][75 - Influenza virus]]
  • the date the unit is notified that the swab was negative is the "negative date" to put in the TMP file (time is not required)
  • leave the suspect date in the TMP file even if the swab in negative.
  • If the patient is discharged or death occurs prior to the swab results then code[[Disseminated Infection]-68-unknown pathogen
  • Suspect and confirmed dates remain the same if patients move to different units.

OTHER H1N1 SUSPECTS

• If patients with other illnesses are either swabbed and isolated and/or treated with antiviral drugs (E.G. oseltamivir (Tamiflu®), zanamivir (Relenza®) and amantadine
  • code with the admit diagnosis (whatever it is)
  • the date the swab was ordered is the "suspect date" to put in the TMP file (time is not required)
  • the date the unit is notified that the swab was positive is the "confirmed date" to put in the TMP file (time is not required)
  • code the patient [[Disseminated Infection][75 - Influenza virus]]
  • the date the unit is notified that the swab was negative is the "negative date" to put in the TMP file (time is not required)
  • leave the suspect date in the TMP file even if the swab in negative.
  • If the patient is discharged or death occurs prior to the swab results then code[[Disseminated Infection]-68-unknown pathogen
  • Suspect and confirmed dates remain the same if patients move to different units.

H1N1 NOT SUSPECTED

• not suspected patients that are admitted with DX of CAP and/or COPD
  • patients who just get swabbed are not suspects
  • not swabbed and isolated and not treated with antiviral drugs then code whatever the diagnosis is ie- CAP with the bacterial pathogen,culture negative or culture not sent and/or COPD.

• not suspected patients that are admitted with the DX of severe flu like symptoms without CAP - code 89 Disseminated Infection
  • if they are not swabbed and isolated or treated with with antiviral drugs-code them 89 Disseminated Infection with the bacterial pathogen, culture negative or not sent.
  • If the patient is discharged or death occurs prior to the culture results then code[[Disseminated Infection]-68-unknown pathogen

REVIEW

• Confirmation of the diagnosis should be marked in chart. Confirmation date is the date that confirmation came from the lab
• If patient is discharged or moved without culture report then TMP option of "suspected H1N1 remains".
• TMP file can have one or two tmp items for H1N1:
  • suspected, with a date
  • suspected with date & confirmed with date(when the unit was notified)
  • suspected with date & negative with date(when the unit was notified)
• If patients have not either been swabbed and isolated and/or not treated with antivirals they are not suspects
• Generally the order for swabs is written on admission, but if the order is written after admission use the date of the order as the "suspect date".
• any patient who is positive for Influenza A should be coded in TMP as a suspected H1N1. H1N1 is a subspecies of Influenza A.Once the swab comes back negative for H1N1 then code CAP with sub code 75 [[influenza virus] or [[Disseminated Infection][75 - Influenza virus]]
• for patients with other illness that are swabbed but not treated or isolated don't code suspected H1N1 unless the swab is positive.Then the suspect date is the time the swab was ordered and the confirmation is when the unit is notified of the positive result.The diagnosis would be whatever they where admitted with.
• Isolation precautions for H1N1 should be gowns,gloves and mask(total isolation).We are not collecting data for "mask only isolation" in the TASKS on MEDICINE.
• Again if patients are swabbed and isolated and/or treated with antivirals they are H1N1 suspects.
• please make sure H1N1 data for all suspected or confirmed patients is up-to-date when you send.

Data Integrity

No automated data integrity checks for this are done at collection or send time.
