About this study

Official title: Redefining Community Acquired Pneumonia in Older Adults: The Role and Impact of Aspiration

This study will utilize diagnostic imaging and salivary biomarkers to estimate the prevalence of aspiration in older adults with suspected community-acquired bacterial pneumonia (CABP). 150 participants over the age of 60 diagnosed with pneumonia will be recruited into this study. 62 of these participants will be enrolled in a supplemental study.

Read the detailed description

Pneumonia is the most common infectious cause of mortality in older adults. Standard practice for older adults with pneumonia involves hospitalization and antibiotics. However, recent studies suggest that a significant portion of suspected community-acquired bacterial pneumonia (CABP) cases may actually be due to distinct, dysphagia-related aspiration syndromes (e.g. aspiration pneumonia, pneumonitis).

The main study will will assess whether salivary biomarkers (viscoelasticity, substance P) and swallowing function tests can be used to help differentiate CABP from aspiration-related syndromes. The following aims will be completed:

  • Aim 1: Compare salivary properties and health outcomes among older adults with aspiration related pneumonia mimics and those with infectious pneumonia
  • Aim 2: Compare appearance of lung ultrasound findings among older adults with aspiration related pneumonia mimics and those with infectious pneumonia.
  • Aim 3: Describe dysphagia screening results, patient reported swallowing function, salivary properties, oral/nasopharyngeal microbiome profiles, in older adults with pneumonia presenting to the ED.
  • Aim 4: Assess the potential impact of the MeMed BV® test's result on patient management decision making, including antibiotic prescribing and disposition.

A supplemental study will be the first to utilize diagnostic imaging (videofluoroscopic evaluation of swallowing and radionuclide salivagram) to estimate the prevalence of aspiration in older adults with suspected CABP.

  • Aim 1: Determine the prevalence of dysphagia-related aspiration among older adults with pneumonia.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Videofluoroscopic Swallowing StudyDiagnostic test

    Participants enrolled in supplemental study will swallow different barium containing liquid and food boluses types that are captured on fluoroscopic imaging in real time.

  • Nuclear medicine pulmonary aspiration studyDiagnostic test

    Participants enrolled in supplemental study will be administered radiotracer (Tc-99m-Sulfur Colloid) orally and static images of the chest will then be obtained at specified intervals over the next 2 hours to determine location of the radiotracer.

  • TOR-BSST and 3 oz Water SwallowDiagnostic test

    Also called bedside dysphagia screening; 3 ounce water swallow test

    The research specialist will conduct ten 1 tsp water swallows, one cup sip of water and a 3 ounce water swallow test with the patient. After each swallow, the participant is asked to say "ah" so that their voice quality can be assessed.

  • Sputum CultureDiagnostic test

    Patients will have sputum collected during stay (ED participants only)

  • MeMed BV®Diagnostic test

    A blood test to help determine if the infection is viral or bacterial (ED participants only)

  • Lung UltrasoundDiagnostic test

    To image the lungs (ED participants only)

  • Respiratory Function TestsDiagnostic test

    Also called manometer, peak cough flow

    To measure respiratory pressures.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants with Aspiration

    As defined by VFSS and radionuclide salivagram imaging studies.

    Measured: up to 6 months on study

Secondary outcomes (10)
  1. Salivary extensional viscosity

    Extensional viscosity will be determined using an extensional rheometer (Thermo-Fisher CaBER) and will be recorded 3 times per sample.

    Measured: Any point during follow up within 6 months of index visit

  2. Salivary Substance P Concentration

    Substance P is a salivary protein

    Measured: Any point during follow up within 6 months of index visit

  3. Salivary pH

    Salivary pH will be measured using a digital pH meter.

    Measured: Any point during follow up within 6 months of index visit

  4. Recurrent pneumonia

    As assessed on medical chart review

    Measured: Any point during follow up within 6 months of index visit

  5. Lung Ultrasound Findings for ED participants

    Lung ultrasound exams will be compared between older adults with aspiration related pneumonia mimics and those with infectious pneumonia. Interpretation of ultrasound images will be performed by two ultrasound fellowship trained EM faculty, blinded to any clinical information. Each lung ultrasound view captured will be reviewed and interpreted descriptively. Lung ultrasound findings will be described with the following features: crisp or irregular pleural line, A line artifacts, isolated Z line artifacts, static air bronchograms, dynamic air bronchograms, tissue-like consolidation without bronchograms, coalescent B lines (presence and how many per interspace), discrete B lines (presence and how many per interspace), subpleural hypoechoic consolidation, and pleural effusion.

    Measured: at ED visit, baseline

  6. Patient Reported Swallowing Function as measured by physical symptoms on SWAL-QOL

    All participants will complete self report surveys at their first study visit. The physical symptoms question on the SWAL-QOL asks the participant to identify how often they experienced specific symptoms in the past month, from 1 (almost always) to 5 (never). The total score is transposed to 0-100 with higher scores indicating better swallowing function.

    Measured: at Point of Care visit, up to 6 months

  7. Percent Viral vs. Bacterial Infection for ED participants

    MeMed BV® test results for participants recruited in the ED.

    Measured: at ED visit, baseline

  8. Respiratory Pressure

    Maximum expiratory pressure and maximum inspiratory pressure will be measured using a handheld digital manometer. This test will take approximately 5 minutes.

    Measured: Any point during follow up within 6 months of index visit

  9. Peak Expiratory Flow (PEF)

    A handheld digital peak cough flow meter will be used to assess PEF to quantify cough function. This test will take approximately 3 minutes.

    Measured: Any point during follow up within 6 months of index visit

  10. Forced Expiratory Volume (FEV1)

    A handheld digital peak cough flow meter will be used to assess forced expiratory volume (FEV1) to quantify cough function. This test will take approximately 3 minutes.

    Measured: Any point during follow up within 6 months of index visit
