Description of intervention(s) / exposure
A phase 1 medical device trial investigating the use of a personalised ventilation hood (The Mini Isolation Hood) for use by Emergency Department (ED) patients with suspected or proven infectious respiratory diseases (primarily COVID-19 suspected or confirmed patients). The device can also be used for patient transport throughout the hospital (eg. movement of patient from ED to other hospital areas such as radiology, or the ward).

This non-invasive device comprises a large, transparent, retractable hood which has a fan and filter attached, that mounts directly to an ED trolley. The hood provides a physical barrier to droplet spread, and the ventilation system is designed to induce negative-pressure within the hood to reduce aerosol spread of COVID-19 or other infectious diseases. The hood has a skirt that drapes down over patient's sides and waist, but does not seal around the patient. The hood relies upon air being drawn from the sides of the bed and from the front (near the patient’s abdomen) up to the rear (i.e. away from the healthcare worker who is principally at the front/sides of the patient). The air passes through the fan and through a High Efficiency Particulate Air (HEPA) filter, thereafter returning to the hospital air environment (much like how a mechanical ventilator scrubs and returns air to the local environment).

The device will be used continuously for the duration of the patient's stay in the Emergency Department (including transport within the hospital). The device will be used until (i) the patient has been declared COVID-19 negative, (ii) the patient is discharged from the ED (to home or to a ward), or (iii) the patient elects to withdraw from the study. Use of the device is entirely voluntary, and patients may elect to cease use of the device at any time either temporarily or permanently. ED nursing staff, medical and allied health staff will be responsible for administering the device (and will receive specific training in its use). The device can be used for a single patient encounter (hours/days), but the framework can be cleaned/disinfected for future patient use. Therefore,components of the device can be used for up to 2 years (or more).

Staff will be asked to complete simple data for each clinical shift about device compliance use. In addition, measures to capture technical product adverse events and complaints will be captured by forms available to clinical staff and checked regularly by the investigator team. Technical product complaint data will be submitted to an independent data safety monitor team.

Staff training and education will be provided by the clinical research team (Doctor who is an Intensive Care and Anaesthetic consultant, and a dedicated critical care research nurse). In-service education sessions will be in a single session of approx. 40 min duration, consisting of both video training and hands-on training. The training video will be provided for staff to view at any time. This education approach will be conducted approx one-week before trial commencement, and will continue throughout trial recruitment. There are a number of staff to educate in the ED setting and it will take time to complete education, however the device trial roll-out needs to occur rapidly as the device helps reduce aerosol and droplet exposure of COVID-19 virus to both healthcare workers, as well as cross-exposure to other patients presenting to the ED. When staff have completed video training the online portal provides a certificate of training completion. Internal hospital staff training checklists will also be used to verify completion of training attendance/completion.

Compliance monitoring will be difficult in a busy ED setting, but a compliance monitoring worksheet will be provided for staff to complete.

Outcomes
Primary outcome [1] 325311 0
Staff satisfaction of device use. Staff will be invited to complete a specifically designed questionnaire about their experience using the device. The questionnaire will ask qualitative questions relating to staff perceived rating of safety, utility features of the device, device interference with patient care, like/dislike of features of device, noise of device, use of the fan, structural integrity, ease of cleaning, use of aerosolizing procedures during patient care, and an overall rating of the device.
Timepoint [1] 325311 0
Questionnaires to be completed voluntarily by clinical staff after caring for the patient using the device (eg. at end of clinical shift). It is anticipated that one to three staff members will care for each patient that uses the device.
Primary outcome [2] 325312 0
Patient satisfaction of device use. The patient will be read a simple statement from the nursing staff, inviting them to answer the specifically designed questionnaire. Qualitative questions asked relate to the perceived feeling of safety within the hood, feeling of claustrophobia, perception of temperature comfort within the hood, noise rating, and interference of the device on communication with staff.
Timepoint [2] 325312 0
Questionnaire to be completed voluntarily by patients, where the patient is awake, cooperative and able to communicate appropriately. Device will be trialed on at least 20 patients, but not all patients may be able to complete the questionnaire. Where appropriate, invitation to complete the questionnaire will be offered at the end of the treatment, upon discharge from the ED (to the ward or home) or when the patient elects to withdraw from the study (whichever occurs first).
Secondary outcome [1] 387473 0
Clinical safety assessment will be performed by collation of technical product complaint forms. The technical product complaint form will capture descriptive information from staff about device malfunction, breakage or incidents related to use of the device. The investigator team will then assess this information and categorise the event against criteria for the following:
Adverse device effect (ADE). Adverse event related to the use of the investigational product.

Adverse event (AE). Any untoward medical occurrence, unintended disease or injury, or untoward clinical signs in subjects, users or other persons, whether or not related to the investigational medical device.

Serious adverse effect (SAE). Any adverse effect that results in any of the following outcomes: death, a life-threatening adverse effect, inpatient hospitalization or prolongation of existing hospitalization, a persistent or injury or permanent impairment to a body structure or a body function.

Unanticipated serious adverse device effect (SADE). Serious adverse device effect which by its nature, incidence, severity or outcome has not been identified in the current version of the risk analysis report.

This report will then be distributed to an independent data safety monitor team for escalation of regulatory reporting as required.
Timepoint [1] 387473 0
Safety assessment data capture can occur at any time throughout clinical use of the device. All staff will be able to submit a technical product complaint form at any time.

Statistical methods / analysis
The staff and patient safety questionnaires are of qualitative design. It is not possible to perform a power analysis of the number of patients/staff required to be enrolled to indicate device success. A convenience sample of at least 20 patients has been determined sufficient for useful qualitative safety data. There is no plan to perform any inferential statistics. Given that each suspected COVID-19 patient will spend up to 24 hours (1-3 nursing shifts) in the Emergency Department, we suspect that each patient receiving a Mini Isolation Hood will generate 3 questionnaires on average, i.e. at least 60 questionnaires in total. If required, recruiting will continue beyond 20 patients until at least 10 patient questionnaires and at least 30 staff questionnaires have been completed.

The staff questionnaire has 18 questions (16 multiple choice, 2 open-ended) to be answered, and the patient questionnaire has 9 questions (7 multiple choice, 2 open-ended) to be answered. Only questionnaires with at least 50% of questions answered will be included. Excluded questionnaires will be examined for themes of interest (safety, efficacy, mobility, etc.). All multiple choice questions shall be ‘worth’ one point. Each questionnaire will be determined to be favourable if at least 50% of the multiple choice questions are answered favourably (ie. 8/16 staff questions, 4/7 patient questions). We propose/deem that a 75% favourable response rate indicates a minimum percentage to declare that the Mini Isolation Hood has successfully passed this safety study. That is, a minimum of 75% of completed staff questionnaires need to have been determined to be favourable. Similarly, 75% of completed patient questionnaires need to have been determined to be favourable. We will also assess responses to open ended questions for the above themes of interest. Since staff are asking patients for their opinions it is probable that most patient questions will be answered.

Other reasons
Clinical research coordinator staff were redeployed to intensive care unit to meet clinical patient surge demand from October 2021 to February 2022. Therefore, in absence of research coordinator staff, the trial conduct could not proceed with this adequate safety and regulatory support. The manufacturer of device has since registered product with the Therapeutic Goods Administration (TGA) and a clinical trial is not required.

Summary
Brief summary
Since December 2019, the coronavirus disease (COVID-19) pandemic has affected millions of people worldwide. Modern hospital negative pressure rooms have high flow rates and negative pressure to prevent the spread of TB, measles etc. Nevertheless, such negative pressure rooms do not prevent droplet spread of the infectious disease to personnel within the room. Western Health and The University of Melbourne conceived and developed a small personalised ventilation hood device (the Mini Isolation Hood) to provide a physical barrier to droplet and aerosol spread. The device is based upon the already extant McMonty personal ventilation hood; the Mini Isolation Hood is significantly smaller, is mobile, and is designed to attach directly to an Emergency Department trauma trolley.

The hood will provide health care workers with protection from droplets and aerosols during routine care, during the administration of specialised oxygen therapies (including high flow oxygen and non-invasive ventilation), and during the conduct of aerosol generating procedures. The hood has a plastic barrier to prevent droplet spread from a COVID-19 or other infectious patient, and a ventilation system to reduce aerosol spread. The hood relies upon air being drawn from the front near the patient’s legs etc. up to the rear, i.e. away from the healthcare worker, who is principally at the front/sides of the patient. The air passes through the fan and then a High Efficiency Particulate Air (HEPA) filter, thereafter returning to the local Emergency Department environment (similar to that for a patient’s mechanical ventilator).

The entire Mini Isolation Hood is designed to be reusable in order to ensure security of supply during the COVID-19 pandemic. The SARS CoV-2 virus is susceptible, amongst other disinfection treatments, to bleach (chlorine based, e.g. ‘Actichlor’ one part per thousand= one tablet per litre), quaternary ammonium chloride based wipes (e.g. ‘Clinell’), and soap/detergent (exposure to soap for 15 minutes). We aim to evaluate the safety of the Mini Isolation Hood in a clinical setting on use with 20 Emergency Department patients.
