"Association of High Risk Factors and Hearing Impairment in Infants-A Hospital Based Study".

The aim of the study was to find the association of various risk factors with permanent hearing impairment in infants. A case-control study was designed on 420 infants with permanent hearing impairment and normal hearing. The case control ratio was 1:1. Alternate sampling method was used for selecting the control group. Review of medical records and parent interview was done to collect the information of risk factors. Family history(adj. OR 7.5; 95% CI 3, 14; P = 0.000), Consanguinity (adj. OR: 4; 95% CI 2,4; P = 0.000), intra uterine infection (adj. OR 18, 95% CI: 2.3-126.5, P = 0.000), post natal infection (adj. OR 3, 95% CI: 1.3-5, P = 0.004), low Apgar score (adj.OR: 4.6, 95% CI: 1.3-15), craniofacial anomaly (OR-4.6, 95% CI: 1.4-9.5, P = 0.005) and low birth weight (adj. OR: 2.3, 95% CI: 1.2-3.8) were significantly associated with hearing impairment. Among the risk factors, intra uterine infection was having highest significant association with permanent hearing impairment. This is followed by family history, low Apgar score, craniofacial anomaly, consanguinity, post natal infection and low birth weight.

Tele-Audiological Surveillance of Middle Ear Status among Individuals with Cleft Lip and/or Palate in Rural South India.

BACKGROUND: A community-based program for the comprehensive management of communication disorders among individuals with cleft lip and/or palate (CLP) was implemented in two rural districts in the state of Tamil Nadu, India. The program was successful in terms of early surgical repair, orthodontic management and speech correction; however, audiological surveillance was challenging due to poor follow-up rates. PURPOSE: The aim of the study was to compare tele-audiological and in-person audiological surveillance to identify the most beneficial approach for the identification and treatment of middle ear disease (MED) in individuals with CLP in this rural community-based program. RESEARCH DESIGN: Quasi-experimental study. STUDY SAMPLE: All beneficiaries older than 5 years actively seeking services in Cuddalore (n = 44) and Thiruvannamalai (n = 65) districts of Tamil Nadu, India, were included in the study. Individuals in Cuddalore district were assigned to the tele-audiological surveillance group, whereas individuals in Thiruvannamalai district were assigned to the in-person audiological surveillance group. METHODS: In the tele-audiological surveillance group, video-otoscopy examinations were performed by trained community-based rehabilitation workers (CBRWs). Pure-tone audiometry and tympanometry were performed by an audiologist from the tertiary care hospital through remotely accessed equipment using broadband internet at the participants' homes and monthly camps. Findings from those with suspected MED were forwarded to the otolaryngologist at the tertiary care hospital for remote diagnoses and treatment plans. Subsequently, CBRWs relayed the otolaryngologist's recommendations to the individuals receiving services at the community. In the in-person audiological surveillance group, video-otoscopy, pure-tone audiometry, and tympanometry were performed by the audiologist following standard testing procedures at monthly camps. Individuals with suspected MED and impacted cerumen were referred for in-person diagnoses and treatment plans. Follow-up audiological surveillance was conducted in both districts after implementation of the otolaryngologist's recommendations. DATA ANALYSIS: The coverage, follow-up rate for intervention and cost-outcomes from the provider's perspective were analyzed and compared between two groups. RESULTS: Tele-audiological surveillance provided superior coverage (68%) compared with in-person audiological surveillance (38%). The tele-audiological surveillance group showed greater follow-up compliance (61%) than the in-person audiological surveillance group (19%) for treatment plans such as cerumen management and hearing aid fitting provided locally. Compared with in-person audiological surveillance, tele-audiological surveillance resulted in cost saving of USD 47 per individual. CONCLUSION: Tele-audiological surveillance was beneficial for the purpose of identifying and providing treatment in patients having CLP with MEDs in rural locations.

Implementation and evaluation of a rural community-based pediatric hearing screening program integrating in-person and tele-diagnostic auditory brainstem response (ABR).

BACKGROUND: In an attempt to reach remote rural areas, this study explores a community-based, pediatric hearing screening program in villages, integrating two models of diagnostic ABR testing; one using a tele-medicine approach and the other a traditional in-person testing at a tertiary care hospital. METHODS: Village health workers (VHWs) underwent a five day training program on conducting Distortion Product Oto Acoustic Emissions (DPOAE) screening and assisting in tele-ABR. VHWs conducted DPOAE screening in 91 villages and hamlets in two administrative units (blocks) of a district in South India. A two-step DPOAE screening was carried out by VHWs in the homes of infants and children under five years of age in the selected villages. Those with 'refer' results in 2nd screening were recommended for a follow-up diagnostic ABR testing in person (Group A) at the tertiary care hospital or via tele-medicine (Group B). The overall outcome of the community-based hearing screening program was analyzed with respect to coverage, refer rate, follow-up rate for 2nd screenings and diagnostic testing. A comparison of the outcomes of tele-versus in-person diagnostic ABR follow-up was carried out. RESULTS: Six VHWs who fulfilled the post training evaluation criteria were recruited for the screening program. VHWs screened 1335 children in Group A and 1480 children in Group B. The refer rate for 2nd screening was very low (0.8%); the follow-up rate for 2nd screening was between 80 and 97% across the different age groups. Integration of tele-ABR resulted in 11% improvement in follow-up compared to in-person ABR at a tertiary care hospital. CONCLUSIONS: Non-availability of audiologists and limited infrastructure in rural areas has prevented the establishment of large scale hearing screening programs. In existing programs, considerable challenges with respect to follow-up for diagnostic testing was reported, due to patients being submitted to traveling long distance to access services and potential wage losses during that time. In this program model, integration of a tele-ABR diagnostic follow-up improved follow-up in comparison to in-person follow-up. VHWs were successfully trained to conduct accurate screenings in rural communities. The very low refer rate, and improved follow-up rate reflect the success of this community-based hearing screening 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.

Identification and Management of Middle Ear Disorders in a Rural Cleft Care Program: A Telemedicine Approach.

PURPOSE: The aim of this study was to devise a grassroots-level strategy for identification and management of middle ear disorders in a community-based program for individuals with cleft lip and palate in 2 rural districts in the state of Tamil Nadu in South India. METHOD: Community workers underwent training to conduct video otoscopy using the ENTraview device. Community workers conducted video otoscopy on 160 individuals with cleft lip and palate between 3 and 35 years old in the community. Middle ear conditions were identified using store-and-forward telepractice. Diagnostic telehearing evaluation was conducted using synchronous pure tone audiometry and tympanometry for those who were identified with tympanic membrane (TM) and/or middle ear diseases (MEDs). A review of data collected over a 13-month period was carried out to assess coverage and follow-up intervention rates. RESULTS: The program was successful in achieving 80% coverage for identification of TM and MEDs within 13 months of program implementation. TM and/or MEDs were identified in 26% (82/320 ears) of those who underwent video otoscopy. Telehearing evaluations were completed on 42 ears of individuals with TM and/or MEDs; 52% (22/42 ears) of these individuals had a minimal, mild, or moderate degree of hearing loss. Regarding follow-up for intervention, 78% qualified for surgical intervention, and 31% qualified for medication. CONCLUSIONS: This grassroots-level telemedicine approach was successful in achieving better coverage, and store-and-forward telepractice helped in providing remote diagnosis and recommendation by otolaryngologists to all individuals with TM/MEDs in the rural community. The follow-up for otological intervention significantly improved from that achieved in the previous years.

Caregivers' perception of speech and language status and related needs in children with cleft lip and palate.

BACKGROUND AND PURPOSE: Comprehensive management for communication disorders in individuals with CLP was provided in a community based program in two rural districts in Tamilnadu, India. This program provides services at the community to empower the families about CLP and treatment options. OBJECTIVE: To document the caregiver perceptions' of communication status and needs in children with repaired CLP. METHOD: Six Focus Group Discussions were conducted in Thiruvannamalai and Cuddalore districts in Tamil Nadu, India. Participants were 55 Caregivers of children (5-12 years of age) with repaired CLP. RESULTS: Most participants were concerned about their child's communication and few expressed concerns about specific errors in speech observed in their children. The caregivers recognized the need for and were willing to avail speech correction services. The focus group discussions highlighted some factors that need to be considered while planning a service delivery program for speech correction. The caregivers' expressed inability to independently carryout home training programs attributing it the lack of cooperation from their children. However they were open to receiving services if it was logistically convenient. CONCLUSION: This study provided the caregiver perceptions' of needs relating to communication in children with CLP. These need to be incorporated in the existing program to develop a model for speech intervention that would be feasible, sustainable and have good compliance.

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.

Planning community-based intervention for speech for children with cleft lip and palate from rural South India: A needs assessment.

BACKGROUND AND AIM: A community-based rehabilitation programme, Sri Ramachandra University-Transforming Faces project, was initiated to provide comprehensive management of communication disorders in individuals with CLP in two districts in Tamil Nadu, India. This community-based programme aims to integrate hospital-based services with the community-based initiatives and to enable long-term care. The programme was initiated in Thiruvannamalai (2005) district and extended to Cuddalore (2011). The aim of this study was to identify needs related to speech among children with CLP, enroled in the above community-based programme in two districts in Tamil Nadu, India. DESIGN: This was a cross-sectional study. PARTICIPANTS AND SETTING: Ten camps were conducted specifically for speech assessments in two districts over a 12-month period. Two hundred and seventeen individuals (116 males and 101 females) >3 years of age reported to the camps. METHODS: Investigator (SLP) collected data using the speech protocol of the cleft and craniofacial centre. Descriptive analysis and profiling of speech samples were carried out and reported using universal protocol for reporting speech outcomes. Fleiss' Kappa test was used to estimate inter-rater reliability. RESULTS: In this study, inter-rater reliability between three evaluators revealed good agreement for the parameters: resonance, articulatory errors and voice disorder. About 83.8% (n = 151/180) of the participants demonstrated errors in articulation and 69% (n = 124/180) exhibited abnormal resonance. Velopharyngeal port functioning assessment was completed for 55/124 participants. CONCLUSION: This study allows us to capture a "snapshot" of children with CLP, living in a specific geographical location, and assist in planning intervention programmes.

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.

Parents' perceptions of tele-audiological testing in a rural hearing screening program in South India.

INTRODUCTION: Tele-diagnostic audiological testing in a hearing screening program for infants and young children is a novel practice, and this study is the first to explore its application in a rural community. It is important to understand parental perceptions and confidence when introducing a new process such as tele-audiological diagnostic testing in rural areas. METHOD: A questionnaire with 17 rater-administered items was designed to elicit comments concerning the quality of tele-hearing testing and video-conferencing, access to tele-hearing testing, and parents' attitudes regarding tele-hearing testing in the village. The questionnaire was administered by an audiologist not involved in tele-diagnostic testing to avoid bias. RESULTS: Parents perceived tele-hearing testing as equal in quality to in-person testing. Technical factors such as good video-conferencing quality and logistical factors such as ease of access due to reasonable travel time to testing facility could have influenced these perceptions. CONCLUSIONS: While these results show tele-hearing testing is an acceptable alternative, occasional poor signal quality should be addressed prior to large-scale implementation.

Multi parametric voice assessment: sri ramachandra university protocol.

Emergence of "Voice specialty clinics" in ENT and Speech Language Pathologist (SLP) practice in India necessitates development of standard protocols for assessment and management of voice disorders. Based on recommendations from European Laryngological Society in Dejonckere (Eur Arch Otorhinolaryngol 258:77-82, 2001), a comprehensive voice assessment protocol was adapted for Indian population. This study aimed at verifying the face validity and feasibility of using the developed voice assessment protocol in a multi specialty tertiary care hospital. It included: history, clinical examination, visual analysis, perceptual analysis, aerodynamic measures, acoustic analysis and patients' self assessment of voice. The developed protocol was administered on 200 patients with voice concerns and problems. Correlation of self assessment with the assessment by the professionals was done using Kendaul tau_b correlation test. The scores of self assessment did not correlate significantly with acoustic measures. Differences in lab findings and self percept of voice indicated that these two were complementary measures in the protocol. Further, diagnosis and management decisions were arrived through a consensus discussion involving the ENT surgeon, SLP and the patient. Vocal hygiene and voice conservation were advised to all patients. Recommendations for voice therapy and/or surgery were provided based on findings from the protocol. The study demonstrated feasibility of using a comprehensive protocol for effective documentation, comparisons, review, training and treatment planning.

Tele-ABR using a satellite connection in a mobile van for newborn hearing testing.

We assessed the feasibility of conducting Auditory Brainstem Response (ABR) testing in a mobile van with satellite connectivity, with the help of trained health workers. ABR recordings in newborn babies made by telemedicine were compared with recordings made face to face. The auditory evoked response equipment was controlled by an audiologist at a nearby hospital. Videoconferencing was used during the testing process to monitor patient preparation by the village health worker. A total of 24 newborns (13 male and 11 female) aged 8-30 days underwent ABR in face-to-face and tele-mode. There was no significant difference between peak V latency measured at three intensity levels in the two modes. Agreement between the two methods of measurement was examined with a Bland-Altman plot. Almost all points were within the limits of agreement, suggesting no bias in the telemedicine measurements. Real-time tele-ABR testing as a component of newborn hearing screening is feasible in a mobile van using satellite link with the assistance of village health workers.

Communication disorders in individuals with cleft lip and palate: An overview.

The need for an interdisciplinary approach in the comprehensive management of individuals with cleft lip and palate is well recognized. This article provides an introduction to communication disorders in individuals with cleft lip and palate for members of cleft care teams. The speech pathologist is involved in identifying those infants who are at risk for communication disorders and also for initiating early intervention to prevent or mitigate communication disorders caused by the cleft. Even with early cleft repair, some children exhibit 'cleft palate speech' characterized by atypical consonant productions, abnormal nasal resonance, abnormal nasal airflow, altered laryngeal voice quality, and nasal or facial grimaces. These manifestations are evaluated to identify those that (a) are developmental, (b) can be corrected through speech therapy alone, and, (c) those that may require both surgery and speech therapy. Speech is evaluated perceptually using several types of stimuli. It is important to identify compensatory and obligatory errors in articulation. When velopharyngeal dysfunction is suspected, the assessment should include at least one direct measure such as nasoendoscopy or videofluoroscopy. This provides information about the adequacy of the velopharyngeal valve for speech production, and is useful for planning further management of velopharyngeal dysfunction. The basic principle of speech therapy in cleft lip and palate is to establish the correct placement of the articulators and appropriate air flow. Appropriate feedback is important during therapy for establishing the correct patterns of speech.

Use of a consensus building approach to plan speech services for children with cleft palate in India.

Cleft lip and palate (CLP) is a common birth defect worldwide. While surgical repair can normalize appearance, debilitating speech disorders frequently persist. Speech-language pathology (SLP) services are needed to address these disorders. However in many regions of the world, there is no discipline of SLP or inadequate numbers of trained clinicians. New models for service delivery must be explored to address the needs of children with CLP. Community-based rehabilitation (CBR) programs represent one model that has been successful in the delivery of other rehabilitation services. This paper presents the outcome of a consensus workshop held in India that explored the application of the CBR model to address the need for SLP services for children with CLP when traditional SLP services are limited or not available.
