Conditions
Brief summary
Augmented Infant Resuscitator (AIR) is an inexpensive add-on, compatible with nearly every existing bag-valve mask and many types of ventilation equipment. AIR monitors ventilation quality and provides real-time objective feedback and actionable cues to clinicians to both shorten training times and improve resuscitation quality, adoption, retention, and confidence.
Detailed description
The investigators propose a randomized controlled trial to asses the impact, feasibility, and acceptability of real-time visual feedback from the AIR device. The study will begin by training and equipping all available skilled birth attendants (SBAs) at the participating facilities in the Helping Babies Breathe (HBB) training curriculum. SBAs will also receive HBB Provider Guides and wall-mountable HBB action plans. Immediately before and after training, the study teams will use the traditional HBB assessment tools to evaluate SBAs' HBB knowledge and skills. Facilities will then be randomized, by cluster, to either receive AIR feedback at the start of the trial (Cohort A) or beginning at 2 (Cohort B) or 4 months post-training (Cohort C). Both intervention and control cohorts will be encouraged to start regular low-dose, high-frequency (LDHF) practice with the AIR devices. LDHF involves frequent doses of shorter, often skills- or competency-based, individual- or pair-learning practice sessions. Study teams will establish HBB practice corners in each health facility, consisting of HBB equipment, NeoNatalie, AIR device, HBB Action Plan, and a log book. Participants in Cohort A will practice with AIR devices providing visual feedback immediately post-training, while Cohorts B and C will start with AIR devices without visual feedback. Disabling feedback from the device does not compromise its recording function that collects time-stamped data on ventilation quality. Cohort B will switch to AIR device feedback at 2 months, and Cohort C will switch to AIR device feedback at 4 months. All cohorts will continue LDHF practice with AIR device feedback through up to 6 months after initial HBB training. During the study, the study teams will conduct facility-based bag-mask ventilation (BMV) assessments at 2, 4, and 6 months. The primary outcome for this measurement will be duration of effective ventilation in a two-minute window after initiation of ventilation, as part of the HBB program's existing BMV skills check and OSCE B. Effective ventilation is defined as ventilating in the correct rate range without airway blockages, significant leaks, and harsh breaths and will be determined by the AIR device. Note, during these skills assessments, study participants will be evaluated with feedback turned off during the two-minute breathing epoch. After AIR feedback is turned on at a facility, de-identified device-recorded data on provider-level frequency and quality of practice will be aggregated, shared, and discussed with each health center every 2 months to support and harmonize with their existing facility-led quality improvement efforts.

Inclusion criteria
* Skilled birth attendants (SBAs) working clinically at the selected facilities (i.e., in-service providers) * SBAs who participate in the HBB training offered by our group at the beginning of the study * SBAs who demonstrate competence, after initial training, in key neonatal resuscitation skills and competencies (i.e., pass the BMV skills check and OSCE B) * SBAs able to adequately understand the language in which the HBB training is offered (e.g., the investigators anticipate the trainings will be offered in English) * SBAs over 18 years of age * SBAs who provide written informed consent for participation in the study
Exclusion criteria
* Students or clinicians still in training (i.e., pre-service providers) * SBAs and other health workers who do not participate in initial HBB training * SBAs that are unable to adequately understand the language in which the HBB training is offered * SBAs under 18 years of age * SBAs who do not provide written informed consent for participation in the study
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Bag-mask ventilation skills 6 months post-training | 6 months after training | Clinicians' bag-mask ventilation skills will be assessed 6 months after training. Assessment of these skills will be done using current standards, namely the HBB program's 'Bag-mask ventilation skills test' and 'OSCE B.' |
| Bag-mask ventilation skills immediately after training | Immediately after training | Clinicians' bag-mask ventilation skills will be assessed immediately after training. Assessment of these skills will be done using current standards, namely the HBB program's 'Bag-mask ventilation skills test' and 'OSCE B.' |
| Bag-mask ventilation skills 2 months post-training | 2 months after training | Clinicians' bag-mask ventilation skills will be assessed 2 months after training. Assessment of these skills will be done using current standards, namely the HBB program's 'Bag-mask ventilation skills test' and 'OSCE B.' |
| Bag-mask ventilation skills 4 months post-training | 4 months after training | Clinicians' bag-mask ventilation skills will be assessed 4 months after training. Assessment of these skills will be done using current standards, namely the HBB program's 'Bag-mask ventilation skills test' and 'OSCE B.' |
| Effective bag-mask ventilation | 2 minutes | Duration of effective bag-mask ventilation by clinician during a 2-minute trial. This is measured internally from the AIR device. Effective ventilation is defined as having all three of the following conditions simultaneously: (1) Correct rate (30-60 breaths per minute); (2) Absence of significant leak (compliance \>4.0mL/cm H2O); and (3) Absence of a significant airway blockage (defined as compliance \<0.10 mL/cm H2O or resistance \>90 cmH2O/L/s). These measurements are determined by sensors in the AIR device for all arms of the study. Their accuracy for manikin use was determined to be 100% in the following trial: Bennett el al. Anesth Analgesia. 2018 Mar;126(3):947-955. doi: 10.1213/ANE.0000000000002432. |
| Time to effective bag-mask ventilation | 2 minutes | How long it takes for clinician to achieve effective ventilation during 2-minute trial -- timed from when the mask first touches the face of the manikin until all three icons are green. This is measured by an observer using a stop-watch. Again, effective ventilation is defined as having all three of the following conditions simultaneously and is indicated to the RA by all three icons on the AIR device turning green: (1) Correct rate (30-60 breaths per minute); (2) Absence of significant leak (compliance \>4.0mL/cm H2O); and (3) Absence of a significant airway blockage (defined as compliance \<0.10 mL/cm H2O or resistance \>90 cmH2O/L/s). |
