Prevalence, recovery and phenotype of dysphagia in patients with ischaemic cerebellar stroke.

BACKGROUND AND PURPOSE: Swallowing is a complex task, moderated by a sophisticated bilateral network including multiple supratentorial regions, the brainstem and the cerebellum. To date, conflicting data exist about whether focal lesions to the cerebellum are associated with dysphagia. Therefore, the aim of the study was to evaluate dysphagia prevalence, recovery and dysphagia pattern in patients with ischaemic cerebellar stroke. METHODS: A retrospective analysis of patients consecutively admitted to an academic stroke centre with ischaemic stroke found only in the cerebellum was performed. The presence of dysphagia was the primary end-point and was assessed by a speech-language pathologist, according to defined criteria. Dysphagia pattern was evaluated by analysing the videos of the flexible endoscopic evaluation of swallowing. Brain imaging was used to identify lesion size and location associated with dysphagia. RESULTS: Between January 2016 and December 2021, 102 patients (35.3% female) with a mean age of 52.8 ± 17.3 years were included. Thirteen (12.7%) patients presented with dysphagia. The most frequently observed flexible endoscopic evaluation of swallowing phenotype was premature spillage (n = 7; 58.3%), whilst significant residues or aspiration did not occur. One patient died (7.7%); the other patients showed improvement of dysphagia and one patient (7.7%) was discharged with dietary restrictions. CONCLUSIONS: Although the involvement of the cerebellum in deglutition has become increasingly evident, isolated lesions to the cerebellum are less likely to cause clinically relevant and persisting dysphagia compared to other brain regions. The observed dysphagia pattern shows a lack of coordination and control, resulting in premature spillage or fragmented bolus transfer in some patients.

Impact of smoking on cost-effectiveness of 10-48 years of periodontal care.

The study aims were (1) to explore whether "periodontal treatment" consisting of surgical therapy (flap, resective, or regenerative) or scaling and root planing treatment with long-term periodontal maintenance treatment, is cost-effective in terms of preventing periodontitis-attributable tooth extraction and replacement by implant-supported crowns ("extraction/replacement"); (2) to assess the effect of cigarette smoking on this cost-effectiveness. Data for this observational retrospective study were collected from dental charts of patients who had received periodontal therapy and at least annual follow-up visits for >10 years were analyzed by linear regression generalized estimating equations and generalized linear models. Among 399 adults (199 males, 200 females), those with the least mean annual treatment cost experienced the greatest mean annual costs for extraction/replacement, indicating general cost-effectiveness. Cigarette smoking adversely impacted this cost-effectiveness, with current heavy smokers experiencing no cost-effectiveness. Former smokers with Grade C periodontitis benefitted most, whereas smoking did not influence cost-effectiveness for Grade B periodontitis. Assessed by mean annual costs of "extraction/replacement," periodontal treatment was cost-effective, which decreased in a dose-response manner by former and current smoking intensity. Cigarette smoking should be factored into treatment planning and cost-effective analyses of periodontal treatment. Smoking cessation should be encouraged.

Physician responses to insurance benefit restrictions: The case of ophthalmology.

This study examines the impact of social insurance benefit restrictions on physician behaviour, using ophthalmologists as a case study. We examine whether ophthalmologists use their market power to alter their fees and rebates across services to compensate for potential policy-induced income losses. The results show that ophthalmologists substantially reduced their fees and rebates for services directly targeted by the benefit restriction compared to other medical specialists' fees and rebates. There is also some evidence that they increased their fees for services that were not targeted. High-fee charging ophthalmologists exhibited larger fee and rebate responses while the low-fee charging group raise their rebates to match the reference price provided by the policy environment.

Cost and availability of selected medicines after implementation of increased import verification fees.

BACKGROUND: Uganda imports approximately 90% of its medicines, with about 60% being distributed by the private sector. To discourage importation and promote local production of 37 selected locally manufactured medicines, the Ugandan government through the Ministry of Health in 2017 increased the import verification fees from 2 to 12%. The increase in verification fees ultimately affects cost and availability of these medicines. This study aimed to assess the cost and availability of the selected essential medicines after the 12% increase in verification fees in Uganda. METHODS: A cross sectional study among 328 wholesale and retail pharmacies and seven key informant interviews was conducted using a pretested data collection checklist and in-depth interview guide from February to September 2021 in Uganda. Data on the availability and prices of the medicines before (2017) and after (2020) the increase in verification fees was collected. Paired sample T-Test was used to test if there is a significant difference in prices before and after the 12% increase in verification fees. RESULTS: Mean availability of imported medicines was higher (54.8%, CI: 49.3-60.4) than the locally produced medicines (37.1%, CI: 31.9-42.7) except for locally manufactured parenteral preparations (54.6.%, CI: 49.1-60.1). Availability of locally produced medicines was mainly low (45%) while the imported medicines were fairly high (74%). Most commonly available locally manufactured medicines were Surgical spirit (89.9%), ORS (86%), Dextrose 5% solution (74.4%), Paracetamol 500 mg Tablets (73.8%) and Sodium Chloride 0.9% solution (72.9%). Most commonly available imported medicines were; Omeprazole 20 mg (94.2%), Amoxicillin Trihydrate 125 mg/5 ml (92.4%), Ciprofloxacin 500 mg (91.4%), Paracetamol Suspension 120 mg/5 ml (91.5%) and Metronidazole 200 mg Tablets (88.1%). Increase in lowest-priced local and imported medicines was significant for 10 (23.8%) and 7 (15.9%) of the medicines respectively. The median prices of imported medicines were generally higher than locally produced medicines. The median unit prices of 12 (28.6%) locally produced medicines and 20 (47.6%) imported medicines were higher than the international median unit prices. CONCLUSIONS: The overall availability of imported medicines was still higher than the local medicines. The median prices of local and imported medicines generally increased or remained the same after the introduction of import verification fees. There is a need for price controls and transparency in the private sector.

A Modified Fiberoptic Endoscopic Evaluation of Swallowing Evaluating Esophageal Dysphagia by a Capsule: A Pilot Study.

While functional endoscopic evaluation of swallowing (FEES) is the most useful diagnostic test for the evaluation of dysphagia, it cannot evaluate the esophageal phase of swallowing. To evaluate if a modification for the FEES exam by swallowing an empty capsule and screening of the upper esophagus could be used for early detection of esophageal dysphagia. A prospective, single-center, pilot study. At the end of a standard FEES exam, the patients were asked to swallow an empty capsule. Fifteen seconds later, the endoscope was inserted into the upper esophagus. A pathological capsule test was defined when the capsule was seen in the esophagus. In such cases, the patient was advised to undergo a gastroscopy, MBS, or esophageal manometry, which were compared to the results of the capsule test. The capsule test was utilized in 109 patients. A pathological capsule test was found in 55 patients (57.8%). In 48 patients (87.3%), an isolated or combined esophageal dysphagia was seen. The accuracy value of the capsule test compared to gastroenterology tests was 83.3%, sensitivity 88.46%, specificity 75%, PPV 85%, and NPV 80%. A modification of the standard FEES exam by including an empty capsule swallow test with an upper esophagus examination may provide a useful screening tool for esophageal dysphagia.

A Tool for the Assessment of Swallowing Safety and Efficiency in Adults: Turkish Adaptation of Boston Residue and Clearance Scale.

The objective of this study was to create a Turkish language adaptation of the Boston Residue and Clearance Scale (BRACS), a validated and reliable tool. The BRACS scale was first translated into Turkish and a Turkish version was subsequently developed. Fiberoptic endoscopic examination of swallowing (FEES) was administered to collect data from 25 dysphagic patients who were hospitalized after a stroke. The recorded films were subjected to editing procedures to ensure their appropriateness for the assessment of swallowing disorders and were then dispatched to a panel of five speech and language therapists for evaluation using the adaptation of the BRACS instrument. The scoring by the experts was evaluated using both explanatory factor analysis (EFA) and confirmatory factor analysis (CFA). Convergent validity, item reliability, and construct (composite) reliability were measured by calculating the average variance extracted (AVE) values. For the 12 location items, EFA revealed 3 main latent factors: the laryngeal vestibule and the oropharynx and hypopharynx. The Turkish BRACS had excellent inter-rater reliability (Krippendorff's alpha coefficient values ranged from 0.93 to 0.95) and high internal consistency (Cronbach's alpha values ranged from 0.88 to 0.93). Inter-rater ICCs for the first and second sessions were 0.83 and 0.85, respectively. CFA showed that all fitted criteria reached acceptable or perfect fit levels. The findings indicated that the proposed factor structure was validated. The AVE values are between 0.61 and 0.73 which was taken as evidence of convergent validity. The Turkish adaptation of the BRACS tool demonstrates both reliablity and validity, rendering it a useful and credible tool for assessing residual severity, particularly in clinical settings.

Analysis of Patients' Dietary Status/Restrictions Following Instrumental Swallow Evaluations in Skilled Nursing Facilities.

Many residents in Skilled Nursing Facilities (SNFs) present with dysphagia and receive altered diets or liquids to minimize the risk of complications. Limited access to timely instrumental evaluations of swallow may impede the best management of these dysphagic residents. De-identified FEES reports completed by a mobile FEES company during a single month, January 2019, were reviewed. Descriptive statistics were used to summarize the pre-study diet/liquid levels and the post-study diet/liquid recommendations. FEES reports (n = 952) were reviewed. Before the FEES evaluation, 209 residents were receiving only non-oral nutrition. After the FEES evaluation, 76% of these residents were recommended to receive oral nutrition. Before the FEES evaluation, 442 (46%) residents were receiving thickened liquids, after the FEES evaluation, 244 (26%) were recommended to have a less restrictive liquid level. Before the FEES evaluation, 576 (60%) residents were receiving altered food texture, after the FEES evaluation, 413 (43%) were recommended to have a less restrictive food texture. The percentage of residents recommended to receive thin liquids increased from 32 to 68% and those recommended to receive a regular diet increased from 18 to 34%. These data indicate that access to instrumental swallow evaluations in the SNF setting generally resulted in lifting liquid and diet restrictions for many residents in the cohort reviewed and potentially improved their quality of life.

Evaluation of the Whiteout During Fiberoptic Endoscopic Evaluation of Swallowing and Examination of Its Correlation with Pharyngeal Residue and Aspiration.

To evaluate the whiteout duration (WOd) and intensity (WOi) during Fiberoptic Endoscopic Evaluation of Swallowing (FEES) and examine their correlation with each other and age, gender, bolus consistencies, residue, and aspiration. Retrospective review of 75 videorecorded FEES. The first swallow of each of the following were scored: "Empty" swallow, semisolids, solids, and liquids (International dysphagia diet standardization initiative (IDDSI) 4, 7, 0, respectively). Data scored for each swallow included WOd, WOi, Penetration and aspiration scale (PAS), Pharyngeal residue (Yale Pharyngeal Residue Severity Rating Scale, YPR-SRS), and saliva pooling (Murray Secretion scale, MSS). The highest PAS and YPR-SRS for each consistency during the entire examination were also collected. WOd was significantly longer for stronger WOi in IDDSI4 swallows (p = 0.019). WOi was weaker for IDDSI0 swallows compared to IDDSI7, IDDSI4, and empty swallows (p < 0.05). Patients with saliva pooling had significantly shorter WOd (0.81 ± 0.3 s for MSS = 0 vs. 0.62 ± 0.24 for MSS = 3, p = 0.04). Lower WOi was associated with higher mean age for IDDSI0 (mean ages of 73 ± 12, 64 ± 14, 73 ± 7, 59 ± 16 years for intensity levels 1-4 respectively, p = 0.019). Swallows with weaker WOi and longer WOd had significantly more aspirations in IDDSI7 (28.8% of PAS ≥ 6 for intensity 2 vs 0% for intensity 4, p = 0.003 and 0.77 ± 0.4 s for PAS 1-2 vs. 1.02 ± 0.08 for PAS 6-8, p = 0.049). WOi and WOd are significantly associated with each other. WOi may vary for different bolus consistencies and decreases with age. Longer WOd and weaker WOi are associated with penetration-aspiration. Shorter WOd is associated with saliva pooling.

Swallowing Characteristics and Water Swallow Capacity in Patients with Parkinsonism.

Prevalence and characteristics of dysphagia (including aspiration) in patients with parkinsonism is variable, depending on type of assessment, diagnosis, disease stage and duration. The aim of this study was to further evaluate dysphagia characteristics in patients with different types of parkinsonism with both instrumental (Flexible Endoscopic Evaluation of Swallowing, FEES) and non-instrumental (Timed Water Swallow Test, TWST) assessments. Swallowing characteristics in 74 patients with parkinsonism were prospectively assessed using FEES and TWST. Statistics employed were (a) Spearman rank correlation to measure correlation between dysphagia results and Parkinson subtypes, disease severity and duration and (b) the non-parametric tests Mann Whitney U and Kruskal Wallis to measure difference between groups. Dysphagia was common, with 50 (67.6%) of the patients demonstrating a mild-severe Dysphagia Outcome Severity Scale (DOSS, level 1-5). During FEES, 42% aspirated and 68% of these had silent aspiration. Aspiration was seen more frequently with increased disease severity as per Hoehn and Yahr (H&Y) (r = .459, p = < 0.001) and disease duration (r = .269, p = .021). Thin liquid (IDDSI level 0) was the most common consistency to aspirate, and the frequency of aspiration decreased with thicker liquids. Dysphagia and aspiration are common in all subgroups of parkinsonism and seen in early stages of H&Y and within the first year of disease duration. Hence, it is recommended that these patients are evaluated early for optimal management and to avoid aspiration-related complications.

Fiberoptic Endoscopy Evaluation of Swallowing (FEES) Findings Associated with High Pneumonia Risk in a Cohort of Patients at Risk of Dysphagia.

Aspiration detected in the fiberoptic endoscopy evaluation of swallowing (FEES) has been inconsistently associated with pneumonia, with no evidence of the risk of pneumonia from other alterations in swallowing safety detected in FEES. We conducted a dynamic, ambidirectional cohort study involving 148 subjects at risk of dysphagia in a tertiary university hospital. Our aim was to determine the risk of pneumonia attributed to alterations in swallowing safety detected during FEES. We used multivariate negative binomial regression models to adjust for potential confounders. The incidence density rate (IR) of pneumonia in patients with tracheal aspiration of any consistency was 26.6/100 people-years (RR 7.25; 95% CI: 3.50-14.98; P < 0.001). The IR was 19.7/100 people-years (RR 7.85; 95% CI: 3.34-18.47; P < 0.001) in those with laryngeal penetration of any consistency and 18.1/100 people-years (RR 6.24; 95% CI: 2.58-15.09; P < 0.001) in those with pharyngeal residue of any consistency. When adjusted for aspiration, the association of residue and penetration with pneumonia disappeared, suggesting that their risk of pneumonia is dependent on the presence of aspiration and that only aspiration is independently associated with pneumonia. This increased risk of pneumonia was significant in uni- and multivariate negative binomial regression models. We found an independently increased risk of pneumonia among patients with dysphagia and aspiration detected during FEES. Alterations in the oral and pharyngeal phases of swallowing, without aspiration, did not increase the risk of pneumonia.

An Unusual Case of Contralateral Hypoglossal and Recurrent Laryngeal Nerve Palsies Following Endotracheal Intubation.

We present an unusual case of a 62-year-old male presenting with contralateral hypoglossal and recurrent laryngeal nerve palsies following endotracheal intubation for emergency cardiac surgery. Postoperative, the patient was referred to Speech and Language Therapy due to concerns regarding the safety of his swallow. Oromotor assessment revealed left-sided tongue weakness and aphonia. Flexible endoscopic evaluation of swallowing (FEES) revealed a right vocal cord palsy and severe oropharyngeal dysphagia. There were no other focal neurological signs. An MRI head did not demonstrate a medial medullary stroke or other intracranial lesion. CT neck showed no abnormality identified in relation to the course of the right vagus nerve or recurrent laryngeal nerve at the skull base or through the neck respectively. The patient required a gastrostomy for nutrition and hydration. He continued to be assessed at several month intervals over the course of a year using FEES to obtain a range of voice, secretion and swallowing outcome measures. The patient commenced intensive dysphagia therapy targeting pharyngeal drive, hyolaryngeal excursion and laryngeal sensation. Swallow manoeuvres were trialled during FEES and a head-turn to the side of the vocal cord palsy during deglutition reduced aspiration risk which expedited return to oral intake. The patient had partial recovery over twelve months. Hypoglossal nerve palsy completely resolved. The right vocal cord remained paralysed however the left vocal cord compensated enabling the patient to produce a normal voice. The patient was able to take thin fluids and regular diet and the gastrostomy was removed.

Fitostimoline® in fibro-endoscopic and trans-nasal trans-speculum septoplasty as a beneficial tool to improve post-surgical outcome: Preliminary results of a case-control study.

OBJECTIVES: Topic treatment can be useful to improve short and long-term nasal outcomes after nasal surgery, reducing discomfort and risk of synechia. This study aimed at evaluating the effect on clinical outcomes of nasal packaging using Fitostimoline® gauze in FESS and septoplasty. METHODS: A case-control study on hospitalized patients was performed in a tertiary referral center. The control group included 20 patients treated with the standard surgical protocol for septoplasty and standard nasal packaging; treatment group included 21 patients underwent same surgical procedure but in whom the nasal tampon was wrapped with a gauze containing Fitostimoline® before being placed into the nose. RESULTS: Patients in treatment group had better outcomes than control; nasal mucosa showed better healing - recovery of normal color- in those patients in whom we applied the Fitostimoline® gauze around tampons. Moreover, 100 % patients in the treatment group did not refer discomfort during at tampon removal versus 60 % subjects in the control group who referred pain, tension or tearing during the same action. CONCLUSION: Our results, although preliminary because of the small cohort of subjects included, suggest that the apposition of a gauze with Fitostimoline® after nasal surgery might improve the mucosal healing with consequent reduction of patients discomfort during the post-surgical period.

Normal values for swallow events during endoscopic evaluation of swallowing: a preliminary study.

PURPOSE: The current investigation aimed to establish preliminary normative data for endoscopic swallow studies (FEES). The investigators collected data for three timing measures (time to whiteout, duration of whiteout, and total swallow time), three swallowing outcomes (safety, efficiency, and number of swallows per bolus), and one physiologic event (glottal response), for both healthy young and older adults using two liquid volumes, one pureed bolus and a solid bolus. METHODS: Blinded raters retrospectively analyzed 65 randomly selected, deidentified videos of endoscopic swallowing examinations from a pool of 163 young and older adults with typical swallowing abilities. Timing measures and analysis of airway invasion, amount of residue, number of swallows, and glottal response were obtained. RESULTS: Preliminary means and quartiles were established for healthy adults in two age groups (young and old), for time to whiteout (WO), number of swallows per bolus, glottal response, Yale Residue Rating Scale Scores, Penetration-Aspiration Scale scores, duration of WO, and total swallow duration. Differences were found between the older and younger groups. CONCLUSION: The current study represents a preliminary attempt to provide quantitative and normative values for FEES. These data represent reference values to which other bolus presentations and populations can be compared. The data represents proof of concept and merits additional investigation. IRB ID: 1756246-2: Approved 2022/06/06. CLINICAL TRIAL REGISTRATION: Study does not meet criteria. DATA REPOSITORY: https://doi.org/10.6084/m9.figshare.25800025 .

Fiberoptic endoscopic evaluation of swallowing (FEES) in children with spinal muscular atrophy type 1: feasibility, swallowing safety and efficacy, and dysphagia phenotype.

PURPOSE: Although dysphagia is a common symptom among patients with Spinal Muscular Atrophy Type 1 (SMA1), scant data exist on the application of Fiberoptic Endoscopic Evaluation of Swallowing (FEES) in this population. The aim was to analyze FEES feasibility, swallow safety and efficacy, dysphagia phenotype, and agreement with VideoFluoroscopic Swallow Study (VFSS) in children with symptomatic, medication-treated SMA1 and oral feeding. METHODS: 10 children with SMA1 underwent FEES. Six patients had also a VFSS. Two clinicians independently rated FEES and VFSS videos. Swallowing safety was assessed using the Penetration-Aspiration scale (PAS). Dysphagia phenotypes were defined according to the classification defined by Warnecke et al. Swallowing efficacy was evaluated with the Yale Pharyngeal Residue Severity Rating Scale (YPRSRS) in FEES, whereas pharyngeal residue was rated as present or absent in VFSS. RESULTS: FEES was performed in all children without complications. Four children tolerated bolus trials during FEES, in 4 children swallowing characteristics were inferred based on post-swallow residues, while 2 children refused to eat and only saliva management was assessed. The dysphagia phenotype of predominance of residue in the piriform sinuses was documented in 7/8 children. The PAS score was < 3 in 3 children and > 5 in one child. Swallowing efficacy was impaired in 8/8 children. VFSS showed complete agreement with FEES. CONCLUSIONS: FEES is a feasible examination in children with SMA1. Swallowing safety and efficacy are impaired in nearly all patients with strong agreement between FEES and VFSS. Dysphagia is characterized by the predominance of residue in the piriform sinus.

The risk factors for silent aspiration: A retrospective case series and literature review.

AIM: Evidence shows that 20%-30% of patients who aspirate do so silently. Research to date has not demonstrated clear evidence to indicate which patients are at higher risk of silent aspiration. Our aim was to use univariate logistic regression analysis of retrospective case review to determine potential patterns of silent aspiration. MATERIALS AND METHODS: We conducted a retrospective analysis of 455 fiberoptic endoscopic evaluation of swallowing (FEES) reports. The patients were divided into four groups: G1 - neurological diseases (n = 93), G2 - head and neck surgery (n = 200), G3 - gastroenterological diseases (n = 94) and G4 - other patients (n = 68). Data included the occurrence or absence of saliva penetration or aspiration, of silent fluid/solid food penetration or aspiration, type of penetration or aspiration, occurrence of cranial nerve paresis, radiotherapy and tracheostomy. Univariate logistic regression was used to evaluate independent risk factors of silent aspiration in the study population. Three models with different independent variables were considered. RESULTS: There is a statistically significant difference in the frequency of occurrence of silent penetration and aspiration within the groups (p < 0.001), with intraglutative being most frequent. Fluid and food penetration and aspiration correlated with saliva penetration and aspiration in all groups (p < 0.001). Cranial nerve paresis (IX and X), radiotherapy and tracheostomy correlate with saliva penetration and aspiration (p = 0.020 for cranial nerve paresis; p = 0.004 for radiotherapy; p < 0.001 for tracheostomy). One hundred and fifteen patients (45.81%) in the subgroup of patients with intraglutative aspiration had cranial nerve paresis (IX, X or IX-X). CONCLUSIONS: Patients who should be prioritised or considered to be at a higher need of instrumental swallowing evaluation are those with IX and X cranial nerve paresis, tracheostomy and those who have had radiotherapy, with saliva swallowing problems, especially after paraganglioma, thyroid and parathyroid glands and middle and posterior fossa tumour surgery. WHAT THIS PAPER ADDS: What is already known on the subject Clinical signs of penetration or aspiration include coughing, throat clearing and voice changes, while silent penetration or aspiration patients aspirate without demonstrating any clinical symptoms. The most common consequences of silent aspiration include aspiration pneumonia, recurrent lower respiratory tract infections and respiratory failure. Additionally, malnutrition and dehydration can be indicators of silent aspiration. Patients may unknowingly reduce their oral intake and lose weight. Retrospective studies have shown that 20%-30% of patients aspirate silently (e.g. patients after stroke, acquired brain injury, head and neck cancer treatment, prolonged intubation). Clinical examination of swallowing can miss up to 50% of cases of silent aspiration. What this paper adds to existing knowledge Currently, silent aspiration is often discussed in neurological literature, but its applications to head and neck surgery are limited. In this study, we identify head and neck surgery patients who should be prioritised or considered to be in higher need of instrumental swallowing evaluation due to a higher risk of silent aspiration. What are the potential or actual clinical implications of this work? Post-treatment structural changes can result in lower cranial nerve paresis (IX, X, XII) and face injury, in which vagus and glossopharyngeal nerves are injured. After tracheostomy and radiotherapy, patients with problems swallowing saliva need careful clinical examination, particularly cranial nerve examination.

Long-term trends in international medical electives fees: a database mining study.

BACKGROUND: Abroad medical electives are recognized as high-impact practice and considered a necessity to provide global health training. As of recently, the COVID-19 pandemic and its related travel restrictions prohibited most international elective activities. Another important barrier to abroad electives that received comparably little attention is elective and application fees, which - combined - may be as high as $5000 per month, and may prevent students with limited financial resources from applying for an international elective. Elective fees have never been systematically analyzed and trends in teaching and application fees have rarely been subject to dedicated scientific investigations. METHODS: Using data from two large elective reports databases, the authors addressed this gap in the literature. The authors analyzed trends in abroad elective fees within the last 15 years in some of the most popular Anglo-American elective destinations among students from Germany, including the United States of America, Australia, New Zealand, the Republic of South Africa, Ireland and the United Kingdom. RESULTS: The authors identified n = 726 overseas elective reports that were uploaded between 2006 and 2020, of which n = 438 testimonies met the inclusion criteria. The United Kingdom and Australia were the most popular elective destinations (n = 123 and n = 113, respectively), followed by the Republic of South Africa (n = 104) and the United States of America (n = 44). Elective fees differed substantially-depending on the elective destinations and time point. Median elective fees were highest in the United States of America (€ 1875 for a 4-week elective between 2018-2020), followed by the Republic of South Africa (€ 400) and Australia (€ 378). The data also suggests an increasing trend for elective fees, particularly in the United States. CONCLUSIONS: Rising fees warrant consideration and a discussion about the feasibility of reciprocity and the bidirectional flow of students in bidirectional exchange programs.

Trends in Medicare Costs of Hyperbaric Oxygen Therapy, 2013 through 2022.

Objective: To analyze Hyperbaric Oxygen Therapy Registry (HBOTR) data to estimate the Medicare costs of hyperbaric oxygen therapy (HBO2) based on standard treatment protocols and the annual mean number of treatments per patient reported by the registry. Methods: We performed a secondary analysis of deidentified data for all payers from 53 centers registered in the HBOTR from 2013 to 2022. We estimated the mean annual per-patient costs of HBO2 based on Medicare (outpatient facility + physician) reimbursement fees adjusted to 2022 inflation using the Medicare Economic Index. Costs were calculated for the annual average number of treatments patients received each year and for a standard 40-treatment series. We estimated the 2022 costs of standard treatment protocols for HBO2 indications treated in the outpatient setting. Results: Generally, all costs decreased from 2013 to 2022. The facility cost per patient per 40 HBO2 treatments decreased by 10.7% from $21,568.58 in 2013 to $19,488.00 in 2022. The physician cost per patient per 40 treatments substantially decreased by -37.8%, from $5,993.16 to $4,346.40. The total cost per patient per 40 treatments decreased by 15.6% from $27,561.74 to $23,834.40. In 2022, a single HBO2 session cost $595.86. For different indications, estimated costs ranged from $2,383.4-$8,342.04 for crush injuries to $17,875.80-$35,751.60 for diabetic foot ulcers and delayed radiation injuries. Conclusions: This real-world analysis of registry data demonstrates that the actual cost of HBO2 is not nearly as costly as the literature has insinuated, and the per-patient cost to Medicare is decreasing, largely due to decreased physician costs.

Characterizing the Validity of Using VASES to Derive DIGEST-FEES Grades.

INTRODUCTION: Visual Analysis of Swallowing Efficiency and Safety (VASES) and Dynamic Imaging Grade of Swallowing Toxicity for Flexible Endoscopic Evaluation of Swallowing (DIGEST-FEES) are two complimentary methods for assessing swallowing during FEES. Whereas VASES is intended to facilitate trial-level ratings of pharyngeal residue, penetration, and aspiration, DIGEST-FEES is intended to facilitate protocol-level impairment grades of swallowing safety and efficiency. The aim of this study was to assess the validity of using VASES to derive DIGEST-FEES impairment grades. METHODS: DIGEST-FEES grades were blindly analyzed from 50 FEES - first using the original DIGEST-FEES grading method (n = 50) and then again using a VASES-derived DIGEST-FEES grading method (n = 50). Weighted Kappa (κw) and absolute agreement (%) were used to assess the relationship between the original DIGEST-FEES grades and VASES-derived DIGEST-FEES grades. Spearman's correlations assessed the relationship between VASES-derived DIGEST-FEES grades with measures of construct validity. RESULTS: Substantial agreement (κw = 0.76-0.83) was observed between the original and VASES-derived grading methods, with 60-62% of all DIGEST-FEES grades matching exactly, and 92-100% of DIGEST-FEES grades within one grade of each other. Furthermore, the strength of the relationships between VASES-derived DIGEST-FEES grades and measures of construct validity (r = 0.34-0.78) were similar to the strength of the relationships between original DIGEST-FEES grades and the same measures of construct validity (r = 0.34-0.83). CONCLUSION: Findings from this study demonstrate substantial agreement between original and VASES-derived DIGEST-FEES grades. Using VASES to derive DIGEST-FEES also appears to maintain the same level of construct validity established with the original DIGEST-FEES. Therefore, clinicians and researchers may consider using VASES to increase the transparency and standardization of DIGEST-FEES ratings. Future research should seek to replicate these findings and explore the simultaneous use of VASES and DIGEST-FEES in a greater sampling of raters and across other patient populations.

How a supply-side intervention can help to increase caesarean section rates in Burkina Faso facilities-Evidence from an interrupted time-series analysis using routine health data.

OBJECTIVES: In Burkina Faso, only 2.1% of women give birth by caesarean section (CS). To improve the use of maternal health services during pregnancy and childbirth, many interventions were implemented during the 2010s including performance-based financing (PBF) and a free maternal health care policy (the gratuité). The objective of this study is to evaluate the impact of a supply-side intervention (PBF) combined with a demand-side intervention (gratuité) on institutional CS rates in Burkina Faso. METHODS: We used routine health data from all the public health facilities in 21 districts (10 that implemented PBF and 11 that did not) from January 2013 to September 2017. We analysed CS rates as the proportion of CS performed out of all facility-based deliveries (FBD) that occurred in the district. We performed an interrupted time series (ITS) analysis to evaluate the impact of PBF alone and then in conjunction with the gratuité on institutional CS rates. RESULTS: CS rates in Burkina Faso increased slightly between January 2013 and September 2017 in all districts. After the introduction of PBF, the increase of CS rates was higher in intervention than in non-intervention districts. However, after the introduction of the gratuité, CS rates decreased in all districts, independently of the PBF intervention. CONCLUSION: In 2017, despite high FBD rates in Burkina Faso as well as the PBF intervention and the gratuité, less than 3% of women who gave birth in a health facility did so by CS. Our study shows that the positive PBF effects were not sustained in a context of user fee exemption.

Financial barriers to primary health care in Aotearoa New Zealand.

BACKGROUND: In Aotearoa New Zealand, co-payments to see a general practitioner (GP, family doctor) or collect a prescription are payable by virtually all adults. OBJECTIVE: To examine the extent to which these user co-payments are a barrier to accessing health care, focussing on inequities for indigenous Maori. METHODS: Pooled data from sequential waves (years) of the New Zealand Health Survey, 2011/12 to 2018/19 were analysed. Outcomes were self-reported cost barriers to seeing a GP or collecting a prescription in the previous year. Logistic regression was used to estimate odds ratios (ORs) of barriers to care for Maori compared with non-Maori, sequentially adjusting for additional explanatory variables. RESULTS: Pooled data included 107,231 people, 22,292 (21%) were Maori. Across all years, 22% of Maori (13% non-Maori) experienced a cost barrier to seeing a GP, and 14% of Maori (5% non-Maori) reported a cost barrier to collecting a prescription. The age- and wave-adjusted OR comparing Maori/non-Maori was 1.71 (95% confidence interval [CI]: 1.61, 1.81) for the cost barrier to primary care and 2.97 (95% CI: 2.75, 3.20) for the cost barrier to collecting prescriptions. Sociodemographics accounted for about half the inequity for both outcomes; in a fully adjusted model, age, sex, low income, and poorer underlying health were determinants of both outcomes, and deprivation was additionally associated with the cost barrier to collecting a prescription but not to seeing a GP. CONCLUSIONS: Maori experience considerable inequity in access to primary health care; evidence supports an urgent need for change to system funding to eliminate financial barriers to care.
