Q: What is required to submit in WebDCU for the central IRB?
A: Sites must complete 3 tables in WebDCU. Start with the Site Overview table. Go to [SIREN] Icon in WebDCU – click on [Central IRB] – click on [Site Overview] to complete the table.
Next, complete the Site Regulatory Inspection History table as needed; go to the [SIREN] icon in WebDCU – click on [Central IRB] – click on [Site Regulatory Inspection History]. You must complete a new record for each regulatory inspection for the Investigator or your research location(s) that have occurred in the last 5 years. If there are no inspections, you will need to attest that the site nor the investigator has had any reportable audits in the past 5 years.
Lastly, complete the Initial Site Submission table; go to the [HOBIT] icon in WebDCU – click on [Central IRB] – click on [Initial Site Submission] to complete.
Q: Do subjects need to be consented when they regain the capacity to consent?
A: No. Enrollment will be based on obtaining consent from a legally authorized representative. Subjects will not need to be consented when they gain the capacity to consent. However, subjects may withdraw from the study at any time.
Q: What happens to the equipment that has been installed by Bill Gossett at the monoplace sites after the trial is over? Do the sites keep this?
A: The equipment remains the property of the Federal Government throughout the trial. After the trial ownership will normally be turned over to the hospital.
Q: Where do I find my site’s FWA number?
A: You will need to pull your site’s FWA number from the OHRP website: https://ohrp.cit.nih.gov/search/fwasearch.aspx?styp=bsc.
Q: Who can administer the GOSE exam?
A: We are looking for a neuropsychologist, physician or nurse. This person must be blinded to study treatment.
Q: Can you transport a patient with elevated ICP to the HBO chamber for HBO treatment
A: Subject with persistently elevated ICP despite treatment should not be transported to the HBO chamber. Myringotomy prior to HBO treatments can help with preventing ICP elevation during HBO treatment. While in the HBO chamber, elevated ICP can be treated as per standard of care (see clinical standardization guidelines).
Q: If a subject has a seizure can they still receive HBO treatment?
A: Severe TBI patients are at risk for developing seizures and need prophylaxis with anticonvulsants for 7 days per standard care. All subjects should receive anticonvulsant prophylaxis. Subjects may receive HBO treatments so long as they are not actively seizing. If a subject develops a seizure during HBO treatment, the treatment should be aborted. However, the subject may continue to receive the next scheduled HBO treatment if their seizure is under control. If they seize again during HBO treatment, the treatment should be aborted and future treatments cancelled.
Q: Since HBO treatments are for 5 days, should intracranial monitors (ICP and PbtO2 monitors - if present) be left in place for the entire 5 days?
A: No. Intracranial monitors should only be left in place for as long as it is clinically necessary.
Q: What should I do with remaining treatments if subject starts following commands?
A: If subject starts following commands, treatment should be stopped. However, prior to stopping treatment, please call the PI hotline (833-HOBIT-PI (833-462-4874)) to discuss the case.
Q1: Who does the study say needs to be present with the subject during TRANSPORT to and from the HBO chamber? Q2: Who does the study say needs to be present with the subject during HBO TREATMENT?
A (to Q1 and Q2): During the transport of the HOBIT subject to and from a monoplace or multiplace HBO chamber, there should be at least one clinician trained in ventilatory management and one critical care nurse present and available to address subject’s clinical needs. During the HBO treatment in a monoplace chamber, the HBO nurse and a clinician trained in ventilatory management should be physically present with the subject. For subjects treated in multiplace chambers, a clinician trained in ventilatory management should be physically present with the subject. Institutional policies should also be adhered to
Q: Does an ABG need to be done after the patient is placed on the hyperbaric ventilator?
A: Yes. Ventilation should be adjusted to ensure that the CO2 is documented as within normal limits before HBO treatment.
Q: Is hand bagging with a resuscitation bag allowed during descent and ascent for subjects being treated in a multiplace hyperbaric chamber?
A: It is allowed but there should be some means of monitoring the tidal volume and respiratory rate during these extended times off of the ventilator. For the 2.5 ATA HOBIT profile compressing at 2 feet per minute, this amounts to 50 minutes of hand bagging time
Q: Why is it necessary to have the subject ventilated with their baseline FiO2 up to the time they start the hyperbaric treatment?
A: The HOBIT protocol is set up to evaluate which of the HOBIT treatment arms is effective. This is based on a determined dose of oxygen which has been calculated based on the treatment time of 100% oxygen in the chamber and also the normobaric 100% oxygen time after the hyperbaric treatment. If the subject is placed on 100% oxygen prior to their hyperbaric treatment it will cause uncertainty in the trial results. Also, oxygen toxicity units (OTU’s) were calculated based on 100% oxygen treatment times and depth of treatment in the chamber. Adding more 100% oxygen prior to the hyperbaric treatment will add to their OTU’s and put the subject at risk for pulmonary oxygen toxicity.
Q: Should the ETT cuff be changed back to air after the hyperbaric treatment?
A: No, the ETT cuff should remain filled with NS for the duration of the HOBIT trial hyperbaric treatments. Changing the cuff from air to NS and then back from NS to air after each hyperbaric treatment (10 times in 5 days) can easily damage the cuff and or pilot balloon. It also increases the chance for subglottic oral secretions to be aspirated into the subject’s lungs and set them up for a ventilator associated pneumonia.
Q: Its day 5. Patient has missed HBO treatments on days 2-4. Is it okay to treat subject on day 5 after missing days 2-4? (NEW 10-2-18)
Q: If the ICP is elevated during a dive, what should I do? (NEW 1-11-19)
A: Treat ICP as per the clinical standardization guidelines. However, if ICP cannot be controlled, abort the HBO treatment. Subjects will remain eligible for subsequent HBO treatments so long as their ICP is within normal limits.
Q: Do you have any tips for identifying potential HOBIT subjects who are at high risk for pulmonary dysfunction, before they are randomized? (NEW 1-11-19)
A: Yes. Patients with a high FiO2 requirement (>40%); or an aspiration event; or acute lung injury (contusion, pneumothorax) are all at risk for pulmonary dysfunction. Prior to randomization, these patients need a thorough pulmonary evaluation and optimization of their pulmonary status. A PF ratio should be calculated. If the PF ratio is close to 200 and you have compelling reasons for enrolling the patient, please call the HOBIT PI line to discuss it. However, patients with PF ratio<200 should not be enrolled.
Q: A subject has intractable ICP prior to HBO treatment. Can they still receive HBO treatment? (NEW 2-12-19)
A: Ideally, the ICP should be stablilized prior to transporting the subject for HBO treatment. Treat the ICP according to the clinical standardization guidelines for at least one hour prior to deeming it intractable. In addition, ICP should not be evaluated in isolation. It should be evaluated in the context of the subject's clinical condition, while also considering the MAP and CPP. Since every subject is unique, if you have questions regarding whether a subject is stable enough for HBO treatment, please call the HOBIT PI line.
Q: If a subject has multiple SAEs that are related, should they be reported individually or as one SAE? (NEW 2-12-19)
A: Ideally, if the SAEs are related, they should be reported as one. For example, if a subject has fever, hypoxia and infiltrates on chest x-ray and is suspected to have pneumonia, all these SAEs can be reported as pneumonia. You can report the fever, hypoxia and infiltrates on chest x-ray in the pneumonia SAE. Similarly, if a patient has an elevated ICP and a decreased MAP all due to cerebral edema, you can report cerebral edema and mention elevated ICP and decreased MAP in the cerebral edema SAE.
Q: Should sites bill for HBO treatments done as part of the study?
A: Since HBO treatments will be performed for research reasons, sites should not bill insurance companies for them. The study will make payments of $1000 per dive. However, enrolling sites can bill for non-HBO treatments provided as part of standard TBI clinical management. HBO treatment can be documented in the electronic medical record.
Q: When should critical hypotension or critical decrease in cerebral perfusion pressure (CPP) be recorded as an serious adverse event (SAE)?
A: If the mean arterial pressure (MAP) is <70 mmHg on at least two consecutive measurements that are performed at least 30 minutes apart. During the first 5 days of treatment, all episodes of critical hypotension should be recorded as one SAE. The start time is the time of the first occurrence of critical hypotension and the end time is when the critical hypotension finally resolved. Similarly, critical decrease in CPP is defined as CPP<60 mmHg on at least two consecutive measurements that are performed at least 30 minutes apart. During the first 5 treatment days, all episodes of critical decrease in CPP should be recorded as one SAE. The start time is the time of the first occurrence of critical decrease in CPP and the end time is when the critical decrease in CPP finally resolved.
Q: If an AEs occurs after Day 6 but before hospital discharge, what day would this fall under? (NEW 1-11-19)
A: Enter this AE under Day 6. It will be analyzed based on date of onset.
Q: How do you identify subjects with a Marshall Head CT score >1?
A: Any subject with evidence of traumatic intracranial abnormality on head CT can be classified as having a Marshall Head CT score>1.
Q: Do all HOBIT subjects need to have a Marshall Head CT score>1?
A: No. Subjects with a GCS of 3-6 who do not have an alcohol level > 200 mg.dl do not need to have evidence of traumatic intracranial abnormality prior to enrollment, however, there should be good clinical reason to suspect that their low GCS is due to brain trauma. Subjects with GCS of 7 and 8, and any subject with blood alcohol level greater than 200 mg/dL should have a Marshall Head CT score>1.
Q: When should GCS be obtained?
A: When subject has been resuscitated and is medically stable. Subjects should be off sedatives and paralytics prior to obtaining GCS.
Q: If a subject has a pneumothorax from the presenting trauma, should they be excluded from HOBIT?
A: No. So long as they have a chest tube in place, they can still be enrolled in HOBIT and receive HBO treatments. However, potential subjects with PaO2/FiO2 (PF) ratio<200 despite PEEP of 10 cm of H2O should be excluded from HOBIT.
Q: Should patients with spinal fractures be excluded from HOBIT?
A: Not necessarily. Only those with spinal cord injury and resultant neurologic deficits should be excluded from the study. Subjects without spinal cord injuries who have unstable spine fractures that are securely immobilized (surgical fixation, TLSO, HALO) can be treated with HBO.
Q: We have a potential subject with spinal fracture and possible cord contusion. Subject is neurologically intact. Should they be enrolled? (New 10-2-18)
A: If the fracture is stabilized they can be enrolled. If they are going to need surgical intervention for the fracture, they should not be enrolled.
Q: Can we film the simulation in segments?
A: Yes, sites can divide the simulation video into segments. It does not necessarily have to be done all at once. Sites could do the HBO separate from the ICU, and so forth.
Q: Who should be involved in the simulation?
A: We recommend that the following study personnel should be present for the simulation: the study PI, a study coordinator, ICU physician responsible for caring for TBI patient, a HBO tech, an HBO physician investigator, a respiratory therapist (if that is different from the HBO tech), and an ICU nurse.
Q: How should we film the simulation?
A: We recommend using a smart phone or video camera.
Q: Are there plans for site monitoring?
A: Yes. Onsite monitoring will occur after the enrollment of the first subject at each site. In addition, there will be central data monitoring. There may be additional site monitoring as needed.
Q: How do I add a NEW team member to the database?
A: All study team members will need to be added to the HOBIT database and then added eDOA.
