RESUMO
BACKGROUND: Occlusal splints and anterior repositioning splints (ARSs) are widely accepted treatments for temporomandibular disorders (TMDs). However, there is uncertainty with regard to the most suitable amount of mandibular repositioning. The aim of this study is to evaluate the clinical and functional effects of the therapeutic position (ThP) established based on the Controlled Mandibular Repositioning (CMR) method. METHODS: In this clinical trial, 20 subjects with 37 joints with disc displacement with reduction were recruited. The initial standard functional diagnostic protocol, MRI, and digital condylography were performed, and ThP was calculated with the CMR method. After a 6-month follow-up, the standard diagnostic protocol was repeated. The change in disc position was evaluated by means of MRI after 6 months of CMR therapy. RESULTS: The MRI findings in the parasagittal plane demonstrated that out of the 37 joints presenting disc displacement, 36 discs were successfully repositioned; thus, the condyle-disc-fossa relationship was re-established. Therefore, the success rate of this pilot study was 97.3%. The mean position of the displaced discs was at 10:30 o'clock of the TMJ joint and at 12:00 o'clock after CMR therapy. CONCLUSIONS: The ThP determined using the CMR approach reduced all of the anteriorly displaced discs (except one). The CMR method allowed to define an optimum ThP of the mandible thus supporting patients' effective adaptation to treatment position.
RESUMO
Background: Legislation and accountability frameworks are key components of high-performing deceased-donation systems. In 2021, Nova Scotia (NS), Canada, became the first jurisdiction in North America to enact deemed consent legislation and concurrently implemented mandatory referral legislation similar to that found in other Canadian provinces. Frontline financial resources were provided by the government to support the development of program infrastructure, including implementation of means to evaluate system performance. Methods: The Organ Donation Program (ODP), in collaboration with other stakeholders, developed a Potential Donor Audit (PDA) tool and database for referral intake and manual performance audits. Medical record reviews of deaths in the year before legislative change were conducted to pilot and revise the PDA and evaluate missed donation opportunities. Results: The NS PDA was piloted on 1028 patient deaths. Of 518 patients (50.4%) who met clinical triggers for referral to the ODP, 72 (13.9%) were referred (86.1% missed referral rate). One hundred sixty-three patients met the NS definition of a potential donor; 53 (32.5%) were referred (110 missed potential donors). Referral consent rates reached 71.7% (n = 38 of 53 approaches). The actualized donation rate reported by Canadian Blood Services was 29.9 donors per million population (n = 34 donors). Discussion: We documented high rates of missed referrals and missed potential donors before the enactment of mandatory referral and deemed consent legislation. Conclusions: The ODP has intentionally broadened clinical criteria for referral to shift the responsibility of identifying medically suitable potential donors from bedside clinicians to organ donation specialists. Lessons learned from our experience developing a PDA include the importance of early involvement of multiple stakeholders and ongoing modification of fields and workflow based on data availability and utility for clinical, educational, research, and reporting purposes.
RESUMO
In April 2019, the province of Nova Scotia became the first jurisdiction in North America to pass legislation that incorporated deemed consent for deceased organ donation. The reform included many other important updates, including the hierarchy for consent, enabled donor and recipient contact, and mandatory referral of potential deceased donors. Additionally, system reforms were implemented to improve the deceased donation system in Nova Scotia. A collection of national colleagues identified the magnitude of the opportunity to develop a comprehensive strategy to measure and evaluate the impact of the legislative and system reforms. This article describes the successful development of a consortium from both national and provincial jurisdictions that included experts from a variety of backgrounds and clinical and administrative disciplines. In describing the creation of this group, we hope to offer our case example as a model for the evaluation of other health system reforms from a multidisciplinary perspective.
