Pilot implementation of a computer-based training course on newborn hearing screening and teleaudiology among primary healthcare providers in low resource settings

Objective@#Newborn hearing screening (NHS) in the Philippines has been mandated by law since 2009. However, lack of awareness and knowledge about NHS remains a challenge, especially among healthcare providers. This paper describes the pilot implementation of a computer-based training (CBT) course on NHS and teleaudiology among primary healthcare providers (PHCPs) in rural Philippines. @*Methods@#A four-module web-based training course on newborn hearing screening and teleaudiology in an online learning management system (LMS) was field-tested among PHCPs from eight rural communities in the Philippines. Participants were given four weeks to complete the course. @*Results@#Forty-two PHCPs participated in the CBT. Thirty-four (81%) completed the whole course (mean attrition rate of 4.8% per module) at a mean duration of 10.2 days. Baseline data shows that participants had no NHS training, although the majority (83%) had information and communications technology (ICT) training. Comparison of preand post-test mean scores showed a 24.0% (p<0.001) significant increase in the post-test in all four modules. Passing rates (i.e., score ≥70%) from pre- to post-test increased by 54.6% (range: 38-80% increase). Usability of the CBT was rated high with a mean score of 4.32 out of 5 (range: 4.13 to 4.47), covering all eight parameters. Participants expressed general satisfaction and a positive attitude on CBT to improve knowledge on NHS and teleaudiology. @*Conclusion@#Even in low resource settings where gaps in ICT infrastructure exist, eLearning can be used as an alternative approach to increase awareness and support training of healthcare providers on newborn hearing screening.

Design of a blended learning course for training community healthcare providers on ehealth-enabled newborn hearing screening

Objectives@#We present in this article the design and evaluation of a blended learning approach for training community healthcare providers in performing newborn hearing screening (NHS).@*Methods@#We developed a blended learning course for training community healthcare providers on eHealth-enabled NHS, following Bloom’s revised taxonomy of educational objectives. The training involved three components: computer-based training (CBT), face-to-face (FTF) training, and on-site coaching. We used surveys and post-training interviews following Level 1 Kirkpatrick’s training evaluation model to get initial feedback on the training program. @*Results@#Thirty-one community healthcare providers from five rural health units and a private hearing screening center, with a mean age of 42.2 ± 12.0 years, participated in the pilot. 93.5% of the participants agreed that the program content met stated objectives and was relevant to their practice. The length of the course was perceived to be adequate. Overall satisfaction with the program was rated at 8.5 ± 0.9 (with ten as the highest). The majority expressed that the CBT and FTF course were satisfactory at 93.5% and 100%, respectively. All participants agreed that the course enhanced their knowledge of newborn hearing screening and telehealth. Positive reviews were received from participants on the use of CBT to improve theoretical knowledge before FTF training. Participants declared that FTF training and on-site coaching helped improved NHS skills and implementation. @*Conclusion@#Competent community healthcare providers are critical to strengthening the performance of the health system, and advances in the education and technology sectors offer promising potential in upskilling local healthcare providers. The increasing access of Filipino healthcare providers to improved information and communications technology (ICT) is a significant catalyst for pedagogical innovation, like the use of blended learning in the continuous professional development of health practitioners. As ICTs gradually penetrate the health sector, the challenge we now face is not whether but how we can use innovations in education strategies to benefit healthcare providers.

Pilot implementation of a community-based, eHealth-enabled service delivery model for newborn hearing screening and intervention in the Philippines

Objectives@#This study explores the potential of the HeLe Service Delivery Model, a community-based newborn hearing screening (NHS) program supported by a web-based referral system, in improving provision of hearing care services. @*Methods@#This prospective observational study evaluated the HeLe Service Delivery Model based on records review and user perspectives. We collected system usage logs from July to October 2018 and data on patient outcomes. Semi-structured interviews and review of field reports were conducted to identify implementation challenges and facilitating factors. Descriptive statistics and content analysis were used to analyze quantitative and qualitative data, respectively. @*Results@#Six hundred ninety-two (692) babies were screened: 110 in the RHUs and 582 in the Category A NHS hospital. Mean age at screening was 1.4±1.05 months for those screened in the RHU and 0.46±0.74 month for those in the Category A site. 47.3% of babies screened at the RHU were ≤1 month old in contrast to 86.6% in the Category A hospital. A total of 10 babies (1.4%) received a positive NHS result. Eight of these ten patients were referred via the NHS Appointment and Referral System; seven were confirmed to have bilateral profound hearing loss, while one patient missed his confirmatory testing appointment. The average wait time between screening and confirmatory testing was 17.1±14.5 days. Facilitating factors for NHS implementation include the presence of champions, early technology adopters, legislations, and capacity-building programs. Challenges identified include perceived inconvenience in using information systems, cost concerns for the patients, costly hearing screening equipment, and unstable internet connectivity. The lack of nearby facilities providing NHS diagnostic and intervention services remains a major block in ensuring early diagnosis and management of hearing loss in the community. @*Conclusion@#The eHealth-enabled HeLe Service Delivery Model for NHS is promising. It addresses the challenges and needs of community-based NHS by establishing a healthcare provider network for NHS in the locale, providing a capacity-building program to train NHS screeners, and deploying health information systems that allows for documentation, web-based referral and tracking of NHS patients. The model has the potential to be implemented on a larger scale — a deliberate step towards universal hearing health for all Filipinos.

Evaluation of an investigational hearing screening device (HeLe) to demonstrate acoustic brainstem response among normal-hearing adults

Objective@#This pilot human trial demonstrates the ability of the investigational newborn hearing screening device to provide acoustic stimulation to produce evoked potentials, as well as its ability to capture and acquire auditory evoked potentials, especially the auditory brainstem response (ABR) wave V. This pilot study also demonstrates the ease of recognizing and identifying ABR waves in the graphical presentation of the evoked potentials over time. @*Methods@#Fourteen normal-hearing adults or a total of twenty-eight (28) normal-hearing adult ears underwent auditory brainstem response testing using the investigational hearing screening device. A commercially available auditory brainstem response detection device was used to confirm that the acquired ABR waves of the investigational device are normal. The ABR waves displayed by the investigation device were also reviewed by the clinical audiologists to determine their recognizability and identifiability. @*Results@#The pilot trial demonstrates the ability of the investigational newborn hearing screening device in providing acoustic stimulation to produce evoked potentials, and in acquiring and capturing ABR waves, specifically the wave V, among normal-hearing adult ears. The clinical audiologists recognized and identified the ABR wave V among the evoked potentials at 40dB, 60dB, and 80dB acoustic stimulation. About eighty-nine percent (89.2%) of all ears tested had identifiable and recognizable wave V upon acoustic stimulation at 40dB. @*Conclusion@#The investigational hearing screening device: (1) can provide acoustic stimulation to produce evoked potentials, (2) can accurately capture and acquire these evoked potentials, (3) can present these evoked potentials in a voltage per time graphical display which an audiologist and trained HCP can easily read and interpret (diagnostic ABR), and (4) can present wave V auditory brainstem potentials that can be easily identified by an audiologist and trained HCP (screening ABR).

Hearing screening through frequency analysis of auditory brainstem response using PhysioNet Data

Objectives@#Responding to the reality of neonate patients with delayed childhood development due to late diagnosis of and intervention on hearing impairment, this study aims to determine the features based on time-frequency domain of auditory brainstem response (ABR) signals and to test the protocol on ABR signals from PhysioNet. @*Methods@#This is done by pre-processing, performing time-frequency analysis, and characterizing hearing impairment using the dominant features of the ABR. In this study, normal (N) and hearing impaired (HI) ABR adult human signals were acquired from Physionet.org, a publicly available database. Considering its high signal-to-noise ratio, numerous filters and transformations were applied to extract the ABR. Consequently, the features acquired — dominant frequency and bigrams, were used as data classifiers. @*Results@#Initial results using only N classifiers, that is features from the Normal dataset, and bandpass Chebyshev filter with a lower cut-off frequency of 60 Hz show that the tests yielded low to middle sensitivity. Further tests were done to improve the sensitivity that incorporated the HI classifiers, used data filtered with a low cut-off frequency of 300 Hz, and data divided per stimulus intensity level. @*Conclusion@#Conclusions made are 1) data with both N and HI classifiers have higher sensitivity than those using only N classifiers, 2) data with a Chebyshev cut-off frequency of 300 Hz have a higher sensitivity than those with 60 Hz, and 3) data divided per intensity level have a higher sensitivity than data analyzed as a whole, and that features with stimulus intensity in middle ranges have a better distinction between HI and N patients.

Factors affecting adoption of a telemedicine device by primary care health workers in the Philippines

@#<p style="text-align: justify;"><strong>Background and Introduction.</strong> The RxBox is a telemedicine device that measures and transmits vital signs to remote experts. It has been deployed to primary care health centers (PCHC) in the Philippines serving disadvantaged populations, to decrease morbidity and mortality due to common diseases and poor access to care. Factors affecting its adoption by healthcare workers is unknown.</p><p style="text-align: justify;"><strong>Materials and Methods.</strong> The study determined social and behavioral factors that affect adoption of a telemedicine device into the clinical workflow using the Unified Theory of Acceptance and Use of Technology (UTAUT) framework. This is a mixed methods research using review of records, survey and focused group discussions.</p><p style="text-align: justify;"><strong>Results and Discussion.</strong> RxBox telemedicine devices were installed in 79 primary care health centers (PCHC) and were used a total of 15,705 times within the study period. An ordinary least squares regression analysis using the combined site and individual-level data showed that among the UTAUT parameters, only compatibility, facilitating conditions, and social factors have significant relationships with intent-to-use of the RxBox. The innovation assisted primary care health workers in their clinical responsibilities, improved the stature of their PCHC in the community, and helped in the care for patients. Training and technology support after deployment as well as encouragement by peer and champions (the PCHC physician, local government leaders) reinforced continuous use after training. Users described the experienced improvements in quality of services provided by the PCHC and the consequent benefits to their patients.</p><p style="text-align: justify;"><strong>Conclusions.</strong> These factors should be accounted for in designing strategies to reinforce health workers' attitudes and enhance support towards acceptance and use of novel telemedicine devices into clinical routine in local health centers. Lessons are immediately useful for local leaders in low- and lower middle-income countries that suffer disproportionately from unnecessary maternal deaths and mortality due to non-communicable diseases. This contributes to the body of knowledge and should bolster national-level advocacy to institute an enabling policy on telehealth Information Communication Technology (ICT) and use of Filipino innovations towards health systems strengthening. Results can be used by implementers, evaluators, and regulators of health ICT, especially in resource-poor settings. Likewise, the study can encourage more research in the field to spur more dynamic local health ICT and biomedical device industries.</p>
