ABSTRACT

Despite the rising incidence, currently, there are no early detection methods for HPV-driven HNC (HPV-HNC). Cervical cancer studies suggest that HPV DNA methylation changes can be used as a biomarker to discriminate cancer patients from HPV-infected individuals. As such, this study was designed to establish a protocol to evaluate DNA methylation changes in HPV late genes and long control region (LCR) in saliva samples of HPV-HNC patients and HPV-positive controls. Higher methylation levels were detected in HPV late genes (L1 and L2) in both tumour and saliva samples of HPV-HNC patients compared with HPV-positive controls. Moreover, methylation patterns between tumours and corresponding saliva samples were observed to have a strong correlation (Passing-Bablok regression analysis; τ = 0.7483, P < 0.0001). Considering the differences between HNC and controls in methylation levels in late genes, and considering primer amplification efficiencies, 13 CpG sites located at L1 and L2 genes were selected for further evaluation. A total of 18 HNC saliva samples and 10 control saliva samples were assessed for the methylation levels in the selected sites. From the CpG sites evaluated statistically significant differences were identified for CpG sites at L2-CpG 6 (P = 0.0004), L1-CpG 3 (P = 0.0144), L1-CpG 2 (P = 0.0395) and L2-CpG 19 (P = 0.0455). Our pilot data indicate that higher levels of DNA methylation in HPV late genes are indicative of HPV-HNC risk, and it is a potential supplementary biomarker for salivary HPV detection-based HPV-HNC screening.

ABSTRACT

The clinical prioritisation criteria (CPC) are a clinical decision support tool that ensures patients referred for public specialist outpatient services to Queensland Health are assessed according to their clinical urgency. Medical referrals are manually triaged and prioritised into three categories by the associated health service before appointments are booked. We have developed a method using artificial intelligence to automate the process of categorizing medical referrals based on clinical prioritization criteria (CPC) guidelines. Using machine learning techniques, we have created a tool that can assist clinicians in sorting through the substantial number of referrals they receive each year, leading to more efficient use of clinical specialists' time and improved access to healthcare for patients. Our research included analyzing 17,378 ENT referrals from two hospitals in Queensland between 2019 and 2022. Our results show a level of agreement between referral categories and generated predictions of 53.8%.

ABSTRACT

INTRODUCTION: Speech Language Therapy First Point of Contact Clinic (SLT-FPOCC) models can assist assessment of low-risk patient populations referred to ear, nose and throat (ENT) services. To further improve ENT waitlist management and compliance with best-practice care, consideration of other low-risk populations that could be safely managed through this service model is needed. The aims of this paper are to evaluate the clinical and service outcomes of completing vocal cord check (VCC) assessments for patients' pre and post thyroid/parathyroid surgery within an SLT-FPOCC model and examine consumer perceptions. METHODS & PROCEDURES: The service followed existing SLT-FPOCC procedures, with ENT triaging referrals, then SLT completing pre- and postoperative VCC assessment (interview, perceptual assessment, flexible nasendoscopy), with assessment data later reviewed by ENT to diagnose laryngeal pathology. Clinical and service outcomes were collected prospectively. Patients completed an anonymous post-service satisfaction survey. RESULTS: Of the first 100 patients referred for preoperative VCCs, SLT assessment identified 42 with dysphonia and 30 reporting dysphagia, while ENT confirmed 9 with significant preoperative anatomical findings. Eighty-three underwent surgery, with 63 (95 nerves at surgical risk) returning for a postoperative VCC. Postoperative VCC identified three temporary neuropraxias (3.2%) and three unilateral vocal fold paresis (3.2%). Patients were highly satisfied with the service. All 163 pre-/postoperative VCCs were completed with no adverse events. CONCLUSION & IMPLICATIONS: The current data support SLT-FPOCC service expansion to include pre and post thyroid/parathyroid surgery VCC checks, with positive consumer perception. The model supports delivery of best practice management (i.e., pre- and postoperative VCC) for patients receiving surgery for thyroid/parathyroid dysfunction, and associated efficiencies for ENT services. WHAT THIS PAPER ADDS: What is already known Assessment of laryngeal function via flexible nasoendoscopy is recommended best practice for patients pre and postthyroid/parathyroid surgery, as recurrent laryngeal nerve injury is a low incidence (<10%), yet well-recognised risk of these surgeries. Traditionally, general surgeons refer presurgical patients to ear, nose and throat (ENT) for vocal cord check (VCC) assessment. However, with access to specialist outpatient services under increasing pressure, there is growing support for utilisation of other health professionals, such as speech-language therapists working in first point of contact (FPOCC) models, to assist with the administration of pre- and postsurgical assessments of such low-risk populations. What this study adds This work expands on the emerging body of evidence for speech language therapy (SLT) led FPOCC models within ENT outpatient services, providing clinical and service outcomes to support the safety of a new model designed to administer VCCs for patients pre and post thyroid/parathyroid surgery. Adopting a similar model to a prior published SLT-led FPOCC model, the trained SLT completes the pre- and postsurgical VCC including flexible nasoendoscopy and videostroboscopy, with images and clinical information then presented to ENT for diagnosis and management planning. This study also provides the first data on consumer perceptions of this type of service model. Clinical implications of this study Data on 100 consecutive presurgical patients revealed positive service findings, supporting the safety of this model. Nature and incidence of clinical findings pre and post surgery were consistent with previously published studies using traditional models of care (i.e., ENT completing the flexible nasendoscopy). Consumer perception was positive. This model enables delivery of pre-and postsurgical assessments for patients receiving thyroid/parathyroid surgery, consistent with best practice care, and reduces burden on ENT services. In total 163 ENT appointments were avoided with this model, with positive implications for ENT waitlist management.

ABSTRACT

A girl in her early childhood presented to a regional otolaryngology outpatient clinic with classic signs of benign paroxysmal positional vertigo (BPPV). She reported episodic dizziness when rolling in a supine position. She did not convey any other associated audiovestibular symptoms. A bedside Dix-Hallpike test confirmed geotropic rotational nystagmus indicative of lateral canal BPPV. Due to her young age, limited communicative abilities and concerns for more sinister underlying pathology, a complete neurological examination, MRI and pure tone audiometry were performed. After two sessions of Epley's manoeuvre, she was symptom-free. At her 3-month follow-up, the patient denied any recurrent episodes of vertigo.

ABSTRACT

INTRODUCTION: Telehealth programs are important to deliver otolaryngology services for Aboriginal and Torres Strait Islander children living in rural and remote areas, where distance and access to specialists is a critical factor. OBJECTIVE: To evaluate the inter-rater agreement and value of increasing levels of clinical data (otoscopy with or without audiometry and in-field nurse impressions) to diagnose otitis media using a telehealth approach. DESIGN: Blinded, inter-rater reliability study. SETTING: Ear health and hearing assessments collected from a statewide telehealth program for Indigenous children living in rural and remote areas of Queensland, Australia. PARTICIPANTS: Thirteen board-certified otolaryngologists independently reviewed 80 telehealth assessments from 65 Indigenous children (mean age 5.7 ± 3.1 years, 33.8% female). INTERVENTIONS: Raters were provided increasing tiers of clinical data to assess concordance to the reference standard diagnosis: Tier A) otoscopic images alone, Tier B) otoscopic images plus tympanometry and category of hearing loss, and Tier C) as B plus static compliance, canal volume, pure-tone audiometry, and nurse impressions (otoscopic findings and presumed diagnosis). For each tier, raters were asked to determine which of the four diagnostic categories applied: normal aerated ear, acute otitis media (AOM), otitis media with effusion (OME), and chronic otitis media (COM). MAIN OUTCOME MEASURES: Proportion of agreement to the reference standard, prevalence-and-bias adjusted κ coefficients, mean difference in accuracy estimates between each tier of clinical data. RESULTS: Accuracy between raters and the reference standard increased with increased provision of clinical data (Tier A: 65% (95%CI: 63-68%), κ = 0.53 (95%CI: 0.48-0.57); Tier B: 77% (95%CI: 74-79%), 0.68 (95%CI: 0.65-0.72); C: 85% (95%CI: 82-87%), 0.79 (95%CI: 0.76-0.82)). Classification accuracy significantly improved between Tier A to B (mean difference:12%, p < 0.001) and between Tier B to C (mean difference: 8%, p < 0.001). The largest improvement in classification accuracy was observed between Tier A and C (mean difference: 20%, p < 0.001). Inter-rater agreement similarly improved with increasing provision of clinical data. CONCLUSIONS: There is substantial agreement between otolaryngologists to diagnose ear disease using electronically stored clinical data collected from telehealth assessments. The addition of audiometry, tympanometry and nurse impressions significantly improved expert accuracy and inter-rater agreement, compared to reviewing otoscopic images alone.

ABSTRACT

OBJECTIVE: Although existing studies of audiology first point of contact clinics which screen for retrocochlear pathology have demonstrated positive clinical outcomes, they have provided limited information regarding service impacts. Thus, this study aimed to evaluate both the clinical and health service outcomes of an audiology first point of contact (FPOC) clinic for adults referred to ENT services with suspected retrocochlear pathology. DESIGN: Retrospective cohort study. STUDY SAMPLE: All 1123 patients referred to the clinic over a 6-year period (2013-2019). RESULTS: Most (73.7%) of the 1123 patients referred to the Retrocochlear Clinic were managed and discharged by the audiologist and did not require ENT appointment. Almost half (43.1%) were directly referred for MRI imaging, of which 4 (1.1%) were diagnosed with Vestibular Schwannoma. Waiting times for first appointments significantly (p < 0.001) reduced from a median of 748 days to 63.5 days over the 6-year period. Attendance rates also significantly (p < 0.001) improved over this time (from 52.2% to 90%). There were no adverse events reported. Of those discharged without attending an ENT appointment, 1.8% were rereferred to ENT within 12 months of discharge. CONCLUSIONS: This audiology FPOC Retrocochlear Clinic was shown to be a safe and effective alternative service model.

ABSTRACT

OBJECTIVE: To compare the concordance of advanced audiologists (AA), junior doctors (JD) and paediatric audiologists (PA) with an Ear, Nose and Throat (ENT) specialist on the diagnosis and management of children with middle ear or hearing concerns. DESIGN: A clinical equivalence (concordance) study. STUDY SAMPLE: Three AAs, five JDs, three PAs and one ENT specialist asynchronously reported diagnoses and management plans for ten, online paediatric cases consisting of video-otoscopic images and clinical findings. RESULTS: For medical diagnosis, significant agreement with the ENT specialist was observed at moderate and near-perfect levels for two AAs (k = 0.561 and 0.815), moderate levels for four JDs (k = 0.5 to 0.603) and near-perfect level for one PA (k = 0.815). For management decisions, significant agreement with the ENT specialist was observed at substantial (k = 0.636) and near-perfect (k = 0.818) levels for two AAs, and at a moderate level (k = 0.538) for one PA. Within group inter-rater agreement for management plans was substantial for AAs and JDs, and moderate for PAs. CONCLUSIONS: For children with middle ear disease or hearing concerns, AAs, JDs and PAs showed similar levels of agreement with an ENT specialist on diagnosis, but AAs were more likely than JDs or PAs to agree with an ENT specialist on management.

ABSTRACT

BACKGROUND: As health systems face increasing demands, non-medical prescribing is a workforce redesign strategy adopted within some services. Despite successful implementation in other professional groups, non-medical prescribing within speech pathology (SP) has not yet been described. AIMS: To provide a descriptive account of the development and planned implementation of two SP prescribing models. METHODS & PROCEDURES: The evolution of two SP-led prescribing models, including relevant training and credentialing, for use of (1) nystatin oral drops (100,000 units/mL); and (2) lidocaine (lignocaine) and phenylephrine nasal spray (5 mg/500 µg/spray), in the outpatient setting is detailed. Challenges to implementation are outlined. MAIN CONTRIBUTION: The development of relevant governance structures, a research evidenced-based project evaluation framework, and an overview of training pathways and credentialing was successfully completed. However, implementation of the models was unable to be achieved. A thorough review of the requirements and a discussion of contextual considerations that had a negative influence on the implementation of SP-led prescribing within this specific service context is provided. CONCLUSIONS & IMPLICATIONS: The successful implementation of SP-led prescribing is complex and highly context dependent. This work offers a discussion and review of the complexities of introducing a non-medical prescribing model in an outpatient hospital setting. WHAT THIS PAPER ADDS: What is already known on the subject Allied Health prescribing is an emerging practice area aiming to reduce current pressures on health services. SP-led prescribing has not been thoroughly investigated in the Australian context. What this study adds to existing knowledge This study describes the development of a SP-led prescribing process in the outpatient setting, and a thorough review and discussion of the drivers and barriers to the model's implementation. What are the potential or actual clinical implications of this work? The successful implementation of SP-led prescribing was identified to be complex from a legislative and operational perspective, as well as being highly context dependent. This study further highlights the importance of a thorough context evaluation and workflow mapping prior to full-scale implementation of SP prescribing trials.

ABSTRACT

OBJECTIVE: The advanced audiology-led service is designed to triage and manage children who are referred to Ear Nose and Throat (ENT) outpatient services with middle ear or hearing concerns. This service has resulted in shorter waiting times for children to receive ENT treatment, and improved ENT capacity. The aim of this study was to explore parental satisfaction with the advanced audiology-led ENT service and to determine if there were cultural or process factors affecting satisfaction. DESIGN: Prospective cross-sectional study using a modified Visit-Specific Satisfaction Questionnaire (VSQ-9) survey. STUDY SAMPLE: One hundred and thirteen parents of children consecutively attending a first appointment in the advanced audiology-led service recruited between October 2016 and October 2017. RESULTS: There were a total of 100 valid responses (rate of 88.5%). The survey showed high levels of satisfaction. Satisfaction scores were significantly higher for items related to interactions with the audiologist compared to items related to waiting times. There were no differences in satisfaction across cultural groups. Parents were equally satisfied with the service whether their child was managed independently by the audiologist or required another appointment for medical input. CONCLUSIONS: The advanced audiology-led service had high levels of satisfaction from parents attending with their children.

ABSTRACT

Purpose: Early evidence supports the safety and efficiency of extended scope speech-language pathology (SLP) clinics designed to manage low risk ear nose and throat (ENT) outpatient referrals, however long-term data is lacking. The aim of this study was to complete a 5-year audit of clinical outcomes, including rates of re-referral, for a SLP Allied Health Practitioner (SLP AHP) led dysphagia and dysphonia service within an Integrated Specialist ENT Service.Method: A retrospective audit was undertaken of all patients referred with non-urgent dysphonia and/or dysphagia symptoms over a 5-year period since establishment of the SLP AHP service. Clinical outcomes, rates and reasons for re-referral to the specialist ENT waiting list were investigated.Result: Of 616 patient referrals, 462 patients were seen by the SLP AHP service. Most (72%, n = 333) received all required management through the clinical model, with only 28% (n = 129) requiring additional ENT intervention, consistent with previously published data. Only 36 of the 616 (6%) were re-referred/re-presented within 12 months of first presentation, of which only 12 were referred for same condition as initial referral. No adverse outcomes were recorded on the clinical database during this 5-year period.Conclusion: Results provide further evidence that the SLP AHP service is a safe and efficient method for managing low risk ENT outpatient referrals.

ABSTRACT

AIM: Children with middle ear disease often experience lengthy delays waiting for outpatient paediatric ear nose and throat (ENT) services. This study aimed to investigate whether an alternative service delivery model using audiologists working in an expanded scope of practice reduced waiting times for children to access such services. METHODS: A total of 131 children consecutively referred to a large ENT outpatient service in Queensland, Australia, for middle ear and hearing concerns were prospectively allocated to either a standard ENT service or an advanced audiology (AA)-led service. Waiting times and attendance rates were collected and compared between the two patient groups. RESULTS: The median waiting time from referral to first offered appointment was 96 days for children in the AA-led service versus 417.5 days for children in the standard ENT service. Seventy-nine percent of children in the AA-led service attended their first offered appointment versus 61% in the standard ENT service. For children receiving grommets, the median waiting time from initial referral to grommet insertion was 226 days for children in the AA-led service versus 627 days for children in the standard ENT service. CONCLUSION: The AA-led service was an effective alternative pathway to reduce waiting times for children referred to ENT services with middle ear and hearing concerns.

ABSTRACT

The role of human papillomavirus type 16 (HPV16) in oral potentially malignant disorders (OPMD) and oral cavity carcinoma (OC) is still under debate. We investigated HPV16 prevalence in unstimulated saliva, oral rinse samples, oral swabs and tumour biopsies collected from OPMD (n = 83) and OC (n = 106) patients. HPV16 genotype, viral load, physical status (episomal vs. integrated) and tumour p16INK4a expression were determined. Oral HPV16 prevalence was higher in OC than in OPMD, but this difference was not statistically significant (7.5% (8/106) versus 3.6% (3/83), odds ratio (OR): 2.18, 95% confidence interval (CI): 0.56, 8.48, p = 0.26). There was a significant association (p < 0.05) between oral HPV16 infection and heavy tobacco consumption. Real-time PCR results indicated that no integration events occurred in either OPMD or OC cases based on the HPV16 E2/E6 ratio. HPV16 positive OPMD and OC patients had similar HPV16 E2 and E6 viral loads. The inter-rater agreement between tumour p16INK4a expression and oral HPV16 infection was considered as fair (k = 0.361) for OC. Our data suggest that the involvement of HPV16 in oral carcinogenesis is limited.

ABSTRACT

OBJECTIVES: Expansion of the scopes of practice of allied health practitioners has the potential to improve the efficiency and cost-effectiveness of healthcare, given the identified shortages in medical personnel. Despite numerous examples in other allied health disciplines, this has yet to be applied to pediatric Audiology. This study aimed to investigate the effectiveness and safety of using audiologists with advanced training to independently triage children referred to otolaryngology (ORL) services, and compare the subsequent use of specialist resources, and postoperative grommet care to a standard medical ORL service. DESIGN: One hundred twenty children consecutively referred to a large ORL outpatient service in Queensland, Australia, for middle ear and hearing concerns were prospectively allocated to either the ORL service or Advanced Audiology-led service. Demographic and clinical data were extracted from electronic medical records and compared between the two services. Clinical incidents and adverse events were recorded for the Advanced Audiology-led service. RESULTS: Approximately half of all children referred to ORL for middle ear or hearing concerns were discharged without requiring any treatment, with the remaining half offered surgical treatment. The Advanced Audiology-led model increased the proportion of children assessed by ORL that proceeded to surgery from 57% to 82% compared with the standard medical ORL model. Children followed up by the audiologists after grommet insertion were more likely to be discharged independently and at the first postoperative review appointment compared with the standard medical ORL service. There were no reports of adverse events or long-term bilateral hearing loss after discharge by the Advanced Audiology-led service. CONCLUSIONS: These findings indicate that an Advanced Audiology-led service provides a safe and effective triaging model for the independent management of children not requiring treatment, and children requiring routine postoperative grommet review, and improves the effective use of specialist resource compared with the standard medical ORL service.

ABSTRACT

PURPOSE: Extended scope of practice roles can address health service challenges and enhance patient services; however there has been limited research of extended scope roles in the discipline of speech-language pathology (SLP). The aim of this study was to examine the clinical outcomes and service impacts of a Speech-Language Pathology Allied Health Practitioner (SLP AHP) led dysphagia and dysphonia service within an Integrated Specialist Ear Nose and Throat (ENT) Service. METHOD: Low risk referrals were triaged by ENT from the waiting list into the SLP AHP dysphagia and dysphonia clinic. Outcomes from an initial 6-month pilot phase (n = 43) and 6-month implementation phase (n = 158) were evaluated. RESULT: Approximately 70% of patients managed in the SLP AHP clinic in both phases were discharged without requiring separate ENT appointments. There were no adverse events. In the pilot phase, only 4.3% of medium priority and 10% of low priority referrals were seen within clinically recommended time frames. This improved to 90% in the final three months of the implementation phase. CONCLUSION: With appropriate governance and risk management, an extended scope SLP AHP service for low risk dysphagia and dysphonia can achieve safe, effective and beneficial changes to ENT service delivery.

ABSTRACT

Distant metastasis (DM) from head and neck cancers (HNC) portends a poor patient prognosis. Despite its important biological role, little is known about the cells which seed these DM. Circulating tumour cells (CTCs) represent a transient cancer cell population, which circulate in HNC patients' peripheral blood and seed at distant sites. Capture and analysis of CTCs offers insights into tumour metastasis and can facilitate treatment strategies. Whilst the data on singular CTCs have shown clinical significance, the role of CTC clusters in metastasis remains limited. In this pilot study, we assessed 60 treatment naïve HNC patients for CTCs with disease ranging from early to advanced stages, for CTC clusters utilizing spiral CTC enrichment technology. Single CTCs were isolated in 18/60-30% (Ranging from Stage I-IV), CTC clusters in 15/60-25% (exclusively Stage IV) with 3/15-20% of CTC clusters also containing leukocytes. The presence of CTC clusters associated with the development of distant metastatic disease(P = 0.0313). This study demonstrates that CTC clusters are found in locally advanced patients, and this may be an important prognostic marker. In vivo and in vitro studies are warranted to determine the role of these CTC clusters, in particular, whether leukocyte involvement in CTC clusters has clinical relevance.

ABSTRACT

BACKGROUND: Plunging ranulas are rare mucous extravasation pseudocysts that arise in the floor of the mouth and pass into the submandibular space of the neck. The aim of this study was to investigate the diagnosis, surgical management and outcomes of patients with a plunging ranula at our institution in South East Queensland over a 10-year period. METHODS: A retrospective analysis of adult patients diagnosed with and treated for plunging ranula between 2006 and 2016 at Logan Hospital was conducted. Patient demographics, preoperative investigations, surgical management and post-operative outcomes were collected from medical records. RESULTS: A total of 18 adult patients were treated for plunging ranula. Of the 18 cases, 17 were treated via transoral excision of the sublingual gland. The mean age at presentation was 28.8 years with a 3:1 female to male predominance. Fifty-six percent of patients were of Polynesian descent. The success rate was 94% with only one patient experiencing recurrence and requiring re-excision of remnant sublingual gland tissue. Three patients (17%) developed complications related to post-operative bleeding. There was a slight predominance for right-sided disease (56%) compared with left and one case of bilateral plunging ranulas in this series. CONCLUSION: This study demonstrates that excision of the sublingual gland is an effective and safe treatment for plunging ranula. The majority of plunging ranulas occur in patients aged <30 years with a higher incidence in patients of Polynesian heritage, which is consistent with previous studies suggesting a possible underlying genetic predisposition for this condition.

ABSTRACT

BACKGROUND: Hearing loss is the most common sensory deficit in elderly patients, and is often under-recognised and poorly managed. It is essential for all clinicians to have awareness and knowledge in this field to enable the institution of early and appropriate care. OBJECTIVE: The goal of this article is to review the causes, diagnosis and management of hearing loss as it applies to elderly patients. The review describes a useful approach that clinicians can apply to daily practice. DISCUSSION: For elderly patients presenting with hearing loss, the basic assessment should include history, physical examination and pure tone audiometry. Management depends on the cause and type of hearing loss, and options include medical therapy, surgery and amplification. In the absence of a simple and correctable cause, consider referring patients to an otolaryngologist for further assessment.
