Catheter-Associated Urinary Tract Infection {CAUTI) Monthly Checklist for CAUTI Reporting for the Centers for Medicare and Medicaid Services' Hospital Inpatient
Quality Reporting Program (CMS Reporting Program) via NHSN
Beginning in January, 2015, Acute Care Hospitals participating in the CMS Reporting Program must report CAUTI data from locations defined/mapped as adult and pediatric medical, surgical, and medical/surgical wards, in addition to all adult and pediatric /CUs.
The following steps should be completed prior to the quarterly CMS Reporting Program deadline:
D Verify Your Facility's CMS Certification Number (CCN) An accurate CCN is required for those facilities participating in the CMS Reporting Program, as this is the ID that will
be used to submit CAUTI data to CMS on your behalf. To update the CCN, use the Facility> Facility Info option
within NHSN. At the top of the Facility Information screen, verify and update, if necessary, the CCN in the
appropriate data entry field. If any changes have been made, remember to click the "Update" button at the bottom
of screen. Please be sure to double- and triple-check this number!
D Check the Monthly Reporting Plan each month When NHSN releases CAUTI data to CMS for those hospitals participating in the CMS Reporting Program, only those
months and applicable locations in which the facility included CAUTI in its NHSN monthly reporting plan (MRP) will
be included (i.e., in Plan CAUTI). It is the responsibility of each facility to check their MRPs for compliance with this
requirement.
D Enter denominator data for each required location and month under surveillance Denominator data (i.e., patient days and urinary catheter days) can be entered using the Summary Data > Add
option within NHSN and by selecting the appropriate Denominator Data type (e.g., ICU/Other).
D If no events have been identified, check "Report No Events" on denominator data form Facilities must appropriately Report No Events for those locations and months for which no events of
each type under surveillance were identified. If no events have been reported and this box is not checked, your data
will not be submitted to CMS. For instructions, please see: http://www.cdc.gov/nhsn/PDFs/CMS/how-to-report-No
Events-CLAB-CAU. pdf
D If CAUTI events have been identified, enter the appropriate events
CAUTI events can be entered by using the Event> Add option within NHSN.
D Use NHSN Analysis Tools to check for accuracy and completion The NHSN Analysis Output Option, "SIR - CAUTI Data for CMS IPPS" was created in order to allow facilities to review
those CAUTI data that would be submitted to CMS on their behalf. For more information about this output option,

Surgical Site Infection (SSI) Monthly Checklist for SSI Reporting for the Centers for Medicare and Medicaid Services' Hospital Inpatient
Quality Reporting Program (CMS Reporting Program) via NHSN
The following steps should be completed prior to the quarterly CMS Reporting Program deadline:
D Verify Your Facility's CMS Certification Number (CCN)
An accurate CCN is required for those facilities participating in the CMS Reporting Program, as this is the ID that will
be used to submit SSI data to CMS on your behalf. To update the CCN, use the Facility> Facility Info option within
NHSN. At the top of the Facility Information screen, verify and update, if necessary, the CCN in the appropriate data
entry field. If any changes have been made, remember to click the "Update" button at the bottom of screen. Please

Healthcare Personnel (HCP) Influenza Vaccination Checklist for Healthcare Personnel (HCP) Influenza Vaccination Reporting for the Centers for Medicare and Medicaid Services' Hospital Inpatient Quality Reporting (IQR) Program and Outpatient Quality Reporting (OQR) Program The following steps should be completed prior to the CMS Reporting Program deadline:
D Verify Your Facility's CMS Certification Number (CCN)
An accurate CCN is required for those facilities participating in the CMS Reporting Program, as this is the ID that will be used to submit HCP influenza vaccination data to CMS on your behalf. To update the CCN, use the Facility> Facility Info option within NHSN. At the top of the Facility Information screen, verify and update, if necessary, the CCN in the appropriate data entry field. If any changes have been made, remember to click the "Update" button at the bottom of screen. Please be sure to double- and triple-check this number!
D Activate the Healthcare Personnel Safety Component
HCP Influenza Vaccination reporting is done through NHSN's Healthcare Personnel Safety (HPS) Component. The HPS
Component must be activated by the NHSN Facility Administrator before the facility can report any data.
Instructions for activating the HPS Component can be found in the HCP Influenza Vaccination training slideset at:
http://www.cdc.gov/nhsn/PD F s/traini ng/H CP-fl u-Vaccination-Summarv-Reporti ng-General-Trai ni ng.pdf
D Create a Monthly Reporting Plan in the HPS Component
HCP influenza vaccination data from NHSN will only be sent to CMS for those hospitals participating in the CMS Reporting Program who have included the HCP influenza vaccination summary in their HPS Component monthly reporting plan. Unlike the other NHSN components and modules, when "Influenza Vaccination Summary" is selected on one reporting plan, the information is automatically updated on all reporting plans for the entire influenza season as defined by NHSN (which is July 1 to June 30).
D Enter HCP influenza vaccination summary data for the entire influenza season
The HCP influenza vaccination summary data form must be completed (Flu Summary->Add) for each influenza season. There is only a single form for each influenza season, and the form must be completed by each season's reporting deadline. Data for HCP in inpatient and outpatient departments should be reported together on the same form. Each time a user enters updated data for an influenza season, all previously entered data for that season are overwritten.
D Use NHSN Analysis Tools to check for accuracy and completion
The NHSN Analysis Output Option, "Line Listing - HCP Flu Vaccination Data for CMS IPPS and OPPS" was created to
allow facilities to review the HCP influenza vaccination data that will be submitted to CMS on their behalf. For more
information about this output option, please see Using the uline Listing - HCP Flu Vaccination Data for CMS !PPS

2016 NHSN Patient Safety Component Manual Updates
This document highlights the January 2016 changes, revisions, and updates to the NHSN Patient Safety
Component Manual, which impact the way data are collected and reported to NHSN. Although other minor revisions, not highlighted here, have been made to the manual, they generally represent wording and/or format changes not deemed to significantly impact the collection or reporting ofNHSN data. Besides the changes listed
in this document, it is important to also review the Table of Instructions to ensure that data are collected and reported accurately. Users are expected to follow all updated guidance for definitions, rules, and criteria for events identified on or after January 1, 2016.
Changes Effecting Multiple Protocols
2-2 Fungal Pathogens which are most commonly community acquired and rarely associated with healthcare-associated infections, but which may meet NHSN surveillance criteria for healthcare-associated infections due to long incubation periods, will no longer be included in NHSN HAI reporting. These pathogens are limited to Blastomyces, Histoplasma, Coccidioides, Paracoccidioides, Cryptococcus, and Pneumocystis.
Included in infection criteria
Microbiologic non-culture diagnostic tests that provide organism identification on patient specimens ( e.g. PCR) will be accepted in addition to specimen cultures for infection criteria.
2-2 Specimens for microbiologic non-culture diagnostic testing or culture collected from patients documented brain dead AND maintained awaiting organ harvest will NOT be used for healthcare-associated infection surveillance.
Chapter 1:NHSN Overview
Chapter modified to reflect that the previous Long-Term Care Module is now a separate component in NHSN.
Chapter 2: Identifying Healthcare-associated Infections (HAI) in NHSN
2-2 Table 1 updated to add clarity
2-3 Added clarification and an example to address site-specific infection criteria that do not include a diagnostic test.
2-16 Added clarification and an example to address pathogen assignment related to Secondary BSis and subsequent positive blood cultures

Chapter 4: CLABSI Event
4-2 Added "Impella Heart Device" to list of devices not considered central lines.
4-4, 4-11 Added guidance that allows a BSI that is accompanied by a healthcare worker's documentation in the patient's medical record specifying the patient is suspected of self-injecting into a vascular access device, or is observed to self-inject into a device, to be identified as a healthcare-associated BST, but not a central-line associated BST (CLABST). Documentation must occur during the BSI Infection Window Period.
4-10 Clarified that ANC/WBC levels should NOTnot be used to set the date of MBI-LCBI. The date the patient first meets the LCBI criteria is the date ofthe MBI-LCBI.
4-12 Added exclusion of Salmonella species as pathogens for primary BSI (Laboratory Confirmed Bloodstream Infection).
4-14 Added guidance that if a patient has clear evidence of infection associated with a non-central line site (or non-accessed central line site), the event will be identified as a healthcare-associated BSI, but not a central-line associated BSI (CLABSI). "Clear evidence" required is pus at the insertion site with a culture or microbiologic non-culture diagnostic test which identifies an organism also identified in the blood, during the BSI Infection Window Period.
4-20 Modified the Secondary BSI Guide to provide clarity, and updated examples.
4-25 Added guidance that when a BSI is suspected to be secondary to a lower respiratory tract infection and the BSI cannot be determined to be secondary to V AE, the PNEU definitions are available for secondary BSl assignment
See also General NHSN Surveillance Changes for additional applicable changes.
Chapter 5: CLIP
5-2 Updated requirements for skin prep compliance for Central Line Insertions Practices (CLIP) events for 2016. Only skin prep allowed to meet CLIP bundle adherence is chlorhexidine gluconate (CHG) for patients ::: 60 days old unless there is a documented contraindication to use of CHG recorded in NHSN upon CLIP event entry. CLIP Table oflnstructions provides guidance on recognized contraindications.
Chapter 6: Ventilator-Associated Pneumonia (VAP) Event
6-3 Added a note to emphasize pathogen exclusions apply to secondary BSI assignment for PNEU.

Chapter 11: AUR
The AU Option portion of the protocol was updated to provide information on the new analysis output option that allows facilities that have submitted AU Option data to generate Standardized Antimicrobial Administration Ratios (SAARs) for specific groups of antimicrobials and specific location types. The AR Option of the protocol was updated to clarify the requirements for data submission.

TO Is 2 questions currently conditionally required will move to required status. The questions are "Last physical overnight location of patient immediately prior to arrival into facility" and "Has the patient been discharged from another facility in the past 4 weeks?"
When developed, the LablD Event surveillance module was intended to reduce the manual data collection burden otherwise required to identify MDRO/CDI infection, by providing a proxy measure that focused on data that is more amendable to electronic capture. Requiring these two variables as "required" is not intended to be a departure from this original intent. Substantial benefits could be gained from consistent collection of the data; however, NHSN has reassessed the associated collection burden and determined that, at present, the data may not be retrievable or may be excessively burdensome to collect in some facilities. Therefore, for 2016 LabID Event Reporting, we ask facilities to provide the most accurate information that is available for these fields, making use of the response option "Unknown" if identifying the required information presents undue burden.
2 questions added to CRE reporting. The results for 'production of carbapenemase' will be required for CRE-Klebsiella, CRE-E.coli and CRE-Enterobacter. The questions are "Was the bacterial isolate tested for carbapenemase; Ifyes, then which test was done" and "Did the isolate test positive for carbapenemase; lf yes, identify which carbapenemase were identified."

Identifying Healthcare-associated Infections
Identifying Healthcare-associated Infections (HAI) for NHSN Surveillance
To standardize the classification of an infection as present on admission (POA) or a healthcare-associated
infection (HAI), the following objective surveillance definitions and guidance will be used for NHSN surveillance:
7-day Infection Window Period
Date of Event
POA
HAI
14-day Repeat Infection Timeframe (RIT)
Secondary Bloodstream Infection Attribution Period
To make a proper infection definition determination, proceed in this order: (This doesn't apply to SSls, VAEs, and MDRO/CDI LablD Events)
1. Determine the date of the diagnostic test that is an element of the site-specific criterion.
2. Then from that determine the infection window period (IWP) (3 days before the diagnostic test, the day
of the test and 3 days after for a total of 7 days).
3. Then determine if all of the elements of the criterion are met during the infection window period. If
they are, there is an infection event. If they are not, there is no event.
4. Next determine the date of event (DOE), i.e., the date that the first element used to meet the infection
criterion occurs for the first time within the infection window period.
5. Is the date of event in the POA time period? If yes, the infection is POA, if not, it is an HAI. (POA time
period is defined as the day of admission to an inpatient location, the 2 days before admission, and the
calendar day after admission)
6. Next (if appropriate) determine if the HAI is device-associated, i.e. CAUTI. If the date of event occurred
on or after day 3 of device use, and the device was in place on that day or the day before, the HAI is
device-associated.
7. Using the Transfer Rule if applicable, determine the location to which the HAI should be attributed. If
the date of event is on the date of transfer or discharge, or the next day, the infection is attributed to
the transferring/discharging location. In instances where a patient has been transferred to more than
one location on the date of an infection, or the day before, attribute the infection to the first location in
which the patient was housed the day before the infection's date of event.
8. Set Repeat Infection Timeframe (RIT): The date of event is Day 1 of the 14-day RIT.
9. For infection definition determinations other than BSls, define the Secondary BSI Attribution Period. This
period includes the Infection Window Period combined with the Repeat Infection Timeframe (RIT). It is
14-17 days in length depending upon where, within the infection window period, the date of event
occurs.

Appendixl: Secondary Bloodstream Infection (BSI) Guide (not applicable to Ventilator-associated Events [VAEJ)
The purpose of using the CDC/NHSN infection criteria is to identify and consistently categorize infections that are healthcare-associated into major and specific infection sites or types. LCBI criteria include the caveat that the organism(s) identified from the blood cannot be related to infection at another site (i.e., must be a primary BSI). One must be sure that there is no other CDC/NHSN defined primary site-specific infection that may have seeded the bloodstream secondarily; otherwise the bloodstream infection may be misclassified as a primary BSI and erroneously associated with the use of a central line, i.e., called a CLABSI. For locations performing in-plan VAE surveillance, refer to Fi2:ure 1 in this appendix, as well as the V AE chapter for specific guidance on assigning a secondary BSI to a V AE.
Secondary BSI Scenarios
For purposes ofNHSN, in order for a bloodstream infection to be determined secondary to another site of infection the following requirements must be met: t
The patient must meet one of the NHSN site-specific definitions (CDC/NHSN Surveillance Definitions for Specific Types of Infections, UTI, PNEU or SSI),
AND Either "l" or "2" below must also be true:
1. An organism identified from the site specific infection is used as an element to meet the site-specific infection criterion, AND the blood specimen contains at least one matching organism to that site specific specimen, and is collected during the secondary BSI attribution period.
OR
2. The positive blood specimen is an element used to meet the site-specific infection criterion, and is collected during the site specific infection's infection window period
!Exception:
Necrotizing enterocolitis (NEC) criteria include neither a site-specific specimen nor organism identified from blood specimen, however an exception for assigning a BSI secondary to NEC is provided. A BSI is considered secondary to NEC if the patient meets one of the two NEC criteria AND an organism identified from blood specimen collected during the secondary BSI attribution period is an LCBI pathogen, or the same common commensal is identified from two or more blood specimens drawn on separate occasions on the same or consecutive days.
Below are examples with guidance on how to distinguish between the primary or secondary nature ofa BSI. The definition of "matching organisms" and important notes and reporting instructions are also provided.

See Figure 3: Secondary BSr Guide for algorithmic display of the following instructions.
Scenario 1: An organism identified from the site-specific infection is used as an element to meet the site-specific infection criterion, AND the blood specimen contains at least one matching organism to that site specific specimen. The positive blood specimen must be collected during the site-specific infection's secondary BSI attribution period.
a. Example: Patient meets NHSN criteria for a symptomatic urinary tract infection (suprapubic tenderness and>105 CFU/ml of E. coli) and blood specimen collected during the SUTT secondary BSI attribution period is positive for E. coli. This is a SUTT with a secondary BSl and the reported organism is E. coli.
b. Example: Patient meets NHSN criteria for a symptomatic urinary tract infection (suprapubic tenderness and>105 CFU/ml of E.coli) and blood specimen collected during the SUTI secondary BSI attribution period grows E. coli and P. aeruginosa. This is a SUTI with a secondary BSI and the reported organisms are E. coli and P. aeruginosa, since both site and blood specimens are positive for at least one matching pathogen.
c. Example: Patient meets NHSN criteria for a symptomatic urinary tract infection (suprapubic tenderness and>105 CFU/ml of E.coli) and a single blood specimen collected during the SUTI secondary BSI attribution period E. coli and S. epidermidis. This is a SUTI with a secondary BSI and the reported organism is only E. coli, since the single common commensal S. epidermidis positive blood specimen by itself does not meet BSI criteria.
Scenario 2: The positive blood culture is an element used to meet the site-specific infection criterion, and is collected during the site specific infection's infection
window period. (For your convenience, a list of infection criteria that include positive blood culture as an element are included in Table 5 below).
a. Example: Patient becomes febrile and complains of nausea and abdominal pain. CT scan done that day shows fluid collection suggestive of infection.
Blood specimen collected that day results in identification ofBacteroides .fragilis. Because the patient meets lAB criterion 3b, using the identification of an organisms from the blood specimen as an element (fever, nausea or
abdominal pain, positive blood specimen and CT scan showing infection in abdominal cavity), the BSI is considered secondary to IAB.
b. Example: Patient is febrile, has a new onset of cough and has positive chest imaging test indicating the presence of an infiltrate. Blood specimens collected identify Pseudomonas aeruginosa. Because the patient can meet PNU2 definition by using identification of organisms from blood specimen as one of the elements of the infection criterion (i.e., infiltrate on chest imaging test, fever, new onset of cough and organism identified from blood specimen ), the BSI is considered secondary to PNEU.
January 2016 L (_ (
-
NOTE: In scenarios where an NHSN infection definition can be met using more than one criterion of the infection definition, it is possible that identification of organism from blood and site-specific specimens may not match and a BSI may still be considered as a secondary BSI. Consider the following:
d. Example: During the SSI surveillance period, a postoperative patient becomes febrile and complains of nausea and abdominal pain. CT scan done that day shows fluid collection suggestive of infection. Culture results show Escherichia coli from the T-tube drainage specimen and the blood specimen grows Bacteroides fragilis. Although the organisms in the blood culture and site-specific culture do not match for at least one organism, the blood culture is considered secondary to IAB. This is because the patient meets organ/space SSI IAB criterion 3b, using the identification of organism in blood specimen as an element (fever, nausea or abdominal pain, organisms identified from blood specimen and CT scan showing infection in abdominal cavity). This patient also meets JAB criterion 3a using the positive site culture plus fever, and nausea or abdominal pain even though the organism involved is different from that used for IAB criterion 3b. In this case, the BSI is considered secondary to the organ/space SSI [AB and both organisms would be listed as IAB infection pathogens.
e. Example: Patient is febrile, has a new onset of cough and has positive chest imaging test indicating the presence of an infiltrate. Blood and bronchoalveolar lavage (BAL) specimens are collected. Results identify Klebsiella pneumoniae > 104 CFU/ml from the BAL and Pseudomonas aeruginosa from the blood. Although the organisms in the blood specimen and site-specific specimen do not match for at least one organism, because the patient can meet PNU2 definition using either the identification of organism from blood specimen or BAL specimen as one of the elements of the infection criterion (i.e. infiltrate on chest imaging test, fever, new onset of cough and organism identified from blood specimen or identified from BAL specimen), the blood is considered a secondary BSI to PNEU and both organisms would be listed as PNEU pathogens.
If there is no matching organism identified from blood and site-specific specimen which is used to meet the site-specific infection definition, nor is an organism identified from blood specimen used to meet the site-specific infection criterion, secondary BSI attribution cannot be assigned.
a. Example: Patient has pustules on their abdomen with tenderness and swelling. Purulent material is obtained from the pustules and is positive for Streptococccus Group B. A blood specimen collected the same day
January 2016
-
identifies methicillin resistant Staphylococcus aureus. Because the organisms from the site and blood specimens do not match, and there is no site-specific criterion for SKIN that includes organisms identified from blood specimen, both a site-specific infection, SKIN (criteria I and 2a) and a primary BSI would be reported.
b. Example: A patient has an abscess in the soft tissue around a percutaneous endoscopic gastrostomy (PEG) tube, identified by CT scan, and there is also purulent drainage from that site. No site-specific specimen was collected, but a blood specimen is positive for Staphylococcus aureus. No other sites of infection are identified. Because no culture of the site was collected, and the patient therefore cannot meet ST criterion 1, and because there is no ST criterion which uses identification of organism from blood specimen as an element, this patient has a ST infection with unknown pathogen (criterion 2), and a primary BSI with the pathogen Staphylococcus aureus for NHSN purposes.

as listed
A matching organism is defined as one of the following:
1. Ifgenus and species are identified in both specimens, they must be the same. a. Example: A blood specimen reported as Enterobacter cloacae and an
intraabdominal specimen ofEnterobacter cloacae are matching organisms. b. Example: A blood specimen reported as Enterobacter cloacae and an
intraabdominal specimen ofEnterobacter aerogenes are NOT matching organisms as the species are different.
2. If the organism is less definitively identified in one specimen than the other, the identifications must be complementary.
a. Example: A surgical wound growing Pseudomonas spp. and a blood specimen growing Pseudomonas aeruginosa are considered a match at the genus level and therefore the BSI is reported as secondary to the SSL
b. Example: A blood specimen reported as Candida albicans and a culture from a decubitus reported as yeast not otherwise specified are considered to have matching organisms because the organisms are complementary, i.e. Candida is a type of yeast.

1. Antibiograms of the blood and potential primary site isolates do not have to match. 2. If the blood specimen by itself does not meet BSI criteria ( e.g., only one positive
blood specimen positive for a common commensal), then that specimen may not be used to indicate the presence of a secondary BSI (see scenario le).
Reporting Instructions: For reporting secondary BSI for possible V AP (PV AP), see figure 4 and Chapter
10. Do not report secondary bloodstream infection for vascular (V ASC) infections,
Ventilator-Associated Conditions (VAC), or Infection-related VentilatorAssociated Complications (TVAC), pneumonia 1 (PNEU 1 ).
When a BSI is suspected to be secondary to a lower respiratory tract infection and the BSI cannot be determined to be secondary to V AE, the PNEU definitions are
available for secondary BSI assignment (see Figure 4).
Site-specific organism exclusions apply to secondary BSI attribution as well.
Pathogen Assignment
Pathogens identified from secondary BSls, should be added to those pathogens reported for the primary infection type. The Secondary BSI data collection field should be checked yes.
A secondary BSI pathogen may be assigned to two different primary site infections (e.g., UTI and an IAB infection). In example 1 below, two primary site infections have been identified and a blood culture is collected within both the SUTI and the IAB secondary
BSI attribution period. The blood culture pathogen matches both primary site infection pathogens (SUTI and IAB). Therefore the pathogen is reported for both primary sites of infection as a secondary bloodstream infection.

Pathogens excluded from specific infection definitions (e.g., yeast in UTI, or Enterococcus spp. for PNEU) are also excluded as pathogens for BS Is secondary to that type of infection (i.e., they cannot be added on to one of these infections as a pathogen). ln example 2 below, the excluded organism must be accounted for as either 1) a primary bloodstream infection (BST/CLABS1) or, 2) a secondary bloodstream infection attributed to another primary infection (e.g., IAB, SINU). A blood culture with yeast and E. faecalis is collected during the SUTI RIT. A BSI secondary to SUTI is identified. E. jaecalis is already documented as a pathogen, but the yeast will not be reported as a secondary BSI pathogen, because yeasts are excluded as organisms in the UTI definition. Because no other primary source of infection for which the yeast BSI can be assigned as secondary is found, a primary BSI with yeast is identified.
Note: The Enterococcus faecal is is not reported as a pathogen for the primary BSI because if an excluded organism had not been identified, a primary BSI would not have been reported.

*Secondary BSis may be reported for possible VAP (PY AP) events, provided that at least one
organism identified from the blood specimen matches an organism identified from an appropriate respiratory tract specimen (including respiratory secretions, pleural fluid and lung tissue). The respiratory tract specimen must have been collected on or after the 3rd day ofmechanical ventilation and within 2 calendar days before or after the day of onset of worsening oxygenation to be considered as a criterion for meeting the PV AP definitions. In addition, the blood specimen must have been collected during the 14-day event period, where day 1 is the day of onset of worsening oxygenation.
In cases where PV AP is met with only the histopathology criterion and no culture or non culture based test is performed on an eligible respiratory specimen, and there is also a positive blood specimen, a secondary BSI to V AE is not reported.
In cases where a culture or non-culture based test of respiratory secretions, pleural fluid or lung tissue is performed and does not identify an organism that matches an organism identified from blood, a secondary BSI to V AE is not reported.

Footnotes to Algorithms and Flow Diagrams:
1. Occasionally, in non-ventilated patients, the diagnosis of healthcare-associated pneumonia may be quite clear on the basis of symptoms, signs, and a single definitive chest imaging test result. However, in patients with pulmonary or cardiac disease (e.g., interstitial lung disease or congestive heart failure), the diagnosis of pneumonia may be particularly difficult. Other non-infectious conditions (e.g., pulmonary edema from decompensated congestive heart failure) may simulate the presentation of pneumonia. In these more difficult cases, serial chest imaging test results must be examined to help separate infectious from non-infectious pulmonary processes. To help confirm difficult cases, it may be useful to review multiple imaging test results spanning over several calendar days. Pneumonia may have rapid onset and progression, but does not resolve quickly. Imaging test evidence of pneumonia will persist. Rapid imaging resolution suggests that the patient does not have pneumonia, but rather a non-infectious process such as atelectasis or congestive heart failure.
2. Note that there are many ways of describing the imaging appearance of pneumonia. Examples include, but are not limited to, "air-space disease", "focal opacification", "patchy areas of increased density". Although perhaps not specifically delineated as pneumonia by the radiologist, in the appropriate clinical setting these alternative descriptive wordings should be seriously considered as potentially positive findings.
3. Purulent sputum is defined as secretions from the lungs, bronchi, or trachea that contain 2:25 neutrophils and :::IO squamous epithelial cells per low power field (x 100). Refer to the table below if your laboratory reports these data semi-quantitatively or uses a different format for reporting Gram stain or direct examination results ( e.g., "many WBCs" or "few squamous epithelial cells"). This laboratory confirmation is required since written clinical descriptions ofpurulence are highly variable.
How do I use the purulent respiratory secretions criterion if ...
Instruction
My laboratory reports counts of "white blood cells" or "polymorphonuclear leukocytes" or "leukocytes" rather than counts of "neutrophils"?
Assume that counts of cells identified by these other descriptors (e.g., "white blood cells") are equivalent to counts of neutrophils, unless the laboratory tells you this is not the case.
My laboratory reports semi-quantitative results (not quantitative results) for numbers ofneutrophils and squamous epithelial cells?
Check with the laboratory to get information about what quantitative ranges the semi-quantitative reports correspond to.
My laboratory cannot provide additional information on how its semi-quantitative reporting corresponds to quantitative reporting ranges for neutrophils and squamous epithelial cells?
Use the following direct examination results to meet the purulent respiratory secretions criterion: heavy, 4+, or 2:25 neutrophils per low power field (lpf) [xl 00], AND rare, occasional, few, 1 + or 2+, or :SI O squamous epithelial cells per Jpff x 1001 [191.
My laboratory reports only the numbers of neutrophils present, without reporting the number of squamous epithelial cells?
In this situation, the purulent secretions criterion may be met using the specified quantitative and semiquantitative thresholds for neutrophils alone (i.e.
