Outcomes of Training Nurses Engaged in a Public Sector Newborn Hearing Screening Program in South India.

This study evaluated the outcomes of training nurses engaged in a public sector newborn hearing screening (NHS) program in one urban district in South India. Twenty nurses performing NHS in Corporation Maternity Hospitals (CMH) participated in the training and evaluation. Baseline knowledge and skill of nurses regarding NHS and overall program outcomes were obtained eight months post the initial training. Knowledge was evaluated using questionnaire, skill was evaluated using Objective Structured Clinical Examination (OSCE) and agreement between screening results obtained by audiologist and nurse. Records used for documentation of screening were analysed to evaluate program outcomes. A two-day retraining was designed to address the gaps identified. Evaluations were conducted immediately post and three months post retraining following the same procedure as baseline evaluations. Gaps were identified in knowledge and skill as well as in the program outcomes. Immediate post retraining evaluation results showed overall improvement in nurses' knowledge and skill. Three months post retraining, all the nurses achieved benchmark criteria of 75% in knowledge and skill. Program outcomes, such as coverage (95.3%), refer rate (3.2%) and follow up rate (86.1%) improved post retraining. The findings of this study suggests that knowledge and skill of nurses improved with periodic training. Periodic evaluation and monitoring enhanced the overall outcomes of the program.

School-based language screening among primary school children using telepractice: A feasibility study from India.

Purpose: This study explored the feasibility of conducting school-based language screening using telepractice to expand its scope for providing speech-language pathology services in India. Method: Thirty-two primary school children underwent language screenings through in-person and telemethods. Screening through telemethod was conducted by a Speech-Language Pathologist (SLP) using digitised picture stimuli presented through videoconferencing and remote computing with assistance of a facilitator at school site. Technology and child-related factors influencing screening were documented using an inventory. Result: Language outcomes through in-person and telemethods revealed no significant differences in both receptive and expressive domains, suggesting absence of bias due to testing method used. Use of multiple internet options at both sites helped overcome technical challenges related to connectivity during screening through telemethod. The trained facilitator played a crucial role in overcoming child related factors such as poor speech intelligibility, poor audibility of voice, motivation, interaction with SLP and need for frequent breaks. Conclusion: Feasibility of conducting school-based language screening using multiple internet options and help of a facilitator at school demonstrates promise for delivery of services by SLP in resource constrained contexts such as India.

Cost and outcome of a community-based paediatric hearing screening programme in rural India with application of tele-audiology for follow-up diagnostic hearing assessment.

OBJECTIVE: This study evaluated the cost and outcome of a community-based hearing screening programme in which village health workers (VHWs) screened children in their homes using a two-step DPOAE screening protocol. Children referred in a second screening underwent tele diagnostic ABR testing in a mobile tele-van using satellite connectivity or at local centre using broadband internet at the rural location. DESIGN: Economic analysis was carried out to estimate cost incurred and outcome achieved for hearing screening, follow-up diagnostic assessment and identification of hearing loss. Two-way sensitivity analysis determined the most beneficial cost-outcome. STUDY SAMPLE: 1335 children under 5 years of age underwent screening by VHWs. RESULTS: Nineteen of the 22 children referred completed the tele diagnostic evaluation. Five children were identified with hearing loss. The cost-outcomes were better when using broadband internet for tele-diagnostics. The use of least expensive human resources and equipment yielded the lowest cost per child screened (Rs.1526; $23; €21). When follow-up expenses were thus maximised, the cost per child was reduced considerably for diagnostic hearing assessment (Rs.102,065; $1532; €1368) and for the cost per child identified (Rs.388,237; $5826; €5204). CONCLUSION: Settings with constrained resources can benefit from a community-based programme integrated with tele diagnostics.

Validation of DPOAE screening conducted by village health workers in a rural community with real-time click evoked tele-auditory brainstem response.

OBJECTIVE: This study assessed the validity of DPOAE screening conducted by village health workers (VHWs) in a rural community. Real-time click evoked tele-auditory brainstem response (tele-ABR) was used as the gold standard to establish validity. DESIGN: A cross-sectional design was utilised to compare the results of screening by VHWs to those obtained via tele-ABR. Study samples: One hundred and nineteen subjects (0 to 5 years) were selected randomly from a sample of 2880 infants and young children who received DPOAE screening by VHWs. METHOD: Real time tele-ABR was conducted by using satellite or broadband internet connectivity at the village. An audiologist located at the tertiary care hospital conducted tele-ABR testing through a remote computing paradigm. Tele-ABR was recorded using standard recording parameters recommended for infants and young children. Wave morphology, repeatability and peak latency data were used for ABR analysis. RESULTS: Tele-ABR and DPOAE findings were compared for 197 ears. The sensitivity of DPOAE screening conducted by the VHW was 75%, and specificity was 91%. The negative and positive predictive values were 98.8% and 27.2%, respectively. CONCLUSIONS: The validity of DPOAE screening conducted by trained VHW was acceptable. This study supports the engagement of grass-root workers in community-based hearing health care provision.

School entry level tele-hearing screening in a town in South India - Lessons learnt.

INTRODUCTION: School screening is warranted in developing countries that do not have newborn hearing screening as schools provide access to a large number of young children between 3 and 5 years of age. Due to scarcity of technical manpower and equipment, hearing screening programs are not often conducted in developing countries. In these circumstances, telehealth services appear to be a reasonable solution. Consequently, the purpose of this study was to assess the feasibility of school hearing screening using telehealth technology operated by a practitioner located 400 kms away at a distant hospital. METHOD: Thirty one children received hearing screening procedures in their school. Each child was screened for both in-person and telehealth conditions to assess screening results. Remote computing software was employed for the telehealth condition in order for the practitioner to remotely operate an audiometer, DPOAE system and a video otoscope interfaced to a personal computer at the school site.Teamviewer version 10 was used to provide encrypted videoconferencing and synchronous hearing screening services between the hospital and school sites. All screening was conducted using a mobile phone hotspot or dongle device based internet connection to insure reliable connectivity. RESULTS: The outcome revealed no significant difference between PTA and DPOAE performed in-person and tele-hearing screening methods. Concurrence of greater than 87% was achieved between in-person and tele-video-otoscopy. Strengths and challenges were documented for tele-hearing screening in three different dimensions: technical issues, child related and school related. Understanding these challenges may provide more effective tele-audiology services. DISCUSSION: The results of the study indicate synchronous hearing screening services can be provided in a school setting using mobile hotspot or dongle connectivity in locations where Internet bandwidth is otherwise restricted.
