Outcome assessment of orthodontic clear aligner vs fixed appliance treatment in adolescents with moderate to severe malocclusions.

OBJECTIVE: To compare the efficacy and efficiency of treatment with clear aligners (CAT) vs fixed appliances (FAT) in adolescents with Class I and II moderate to severe malocclusions. MATERIALS AND METHODS: One operator's (Garfinkle) cases from 2014 to 2019, started at age 12-18 years, with pre- and posttreatment records were identified and used according to an institutional review board-approved protocol. Records were measured by two calibrated, blinded investigators, aided by software (OrthoCAD [Cadent, Fairview, N.J.], Dolphin Imaging & Management Solutions [Chatsworth, Calif]). Discrepancy index (DI) and cast radiograph evaluation (CRE) scores, treatment duration, number of scheduled and emergency visits, and reported appliance and interarch elastic wear compliance were compared between groups using Wilcoxon rank sum and Fisher's exact tests. Cephalometric superimpositions were completed to evaluate craniofacial growth and dental changes. RESULTS: Records from 72 cases met the criteria and were included. For the 47 CAT and 25 FAT cases, mean DI (21 ± 5 and 24 ± 8, respectively; P = .20) and CRE (35 ± 10 and 34 ± 9, respectively; P = .90) scores were not significantly different. Other case attributes and reported appliance and interarch elastic wear compliance were also not significantly different. CAT vs FAT cases had significantly smaller treatment durations (24 ± 6 vs 27 ± 5 months; P = .01) and visit numbers (16 ± 5 vs 24 ± 4; P < .01), but emergency visit numbers were not significantly different (2 ± 2 vs 3 ± 2; P = .08). CONCLUSIONS: In adolescents with Class I and II malocclusions and moderate to severe DI scores, on average, CAT vs FAT cases were completed 3 months faster with eight fewer visits, but treatment efficacy was not significantly different.

Toward equity-oriented cancer care: a Strategy for Patient-Oriented Research (SPOR) protocol to promote equitable access to lung cancer screening.

BACKGROUND: Screening for lung cancer with low dose CT can facilitate the detection of early-stage lung cancers that are amenable to treatment, reducing mortality related to lung cancer. Individuals are considered eligible for lung cancer screening if they meet specific high-risk criteria, such as age and smoking history. Population groups that are at highest risk of lung cancer, and therefore, the target of lung cancer screening interventions, are also the least likely to participate in lung cancer screening. This can lead to a widening of health inequities. Deliberate effort is needed to both reduce lung cancer risk (through upstream interventions that promote smoking cessation) as well as midstream interventions that promote equitable access to lung cancer screening. METHODS: This protocol paper describes an equity-informed patient-oriented research study. Our study aims to promote equitable access to lung cancer screening by partnering with patients to co-design an e-learning module for healthcare providers. The learning module will describe the social context of lung cancer risk and promote access to lung cancer screening by increasing equity at the point of care. We have applied the Generative Co-Design Framework for Healthcare Innovation and detail our study processes in three phases and six steps: Pre-design (establishing a study governance structure); Co-design (identifying research priorities, gathering and interpreting data, co-developing module content); and Post-design (pilot testing the module and developing an implementation plan). DISCUSSION: Patient engagement in research can promote the design and delivery of healthcare services that are accessible and acceptable to patients. This is particularly important for lung cancer screening as those at highest risk of developing lung cancer are also those who are least likely to participate in lung cancer screening. By detailing the steps of our participatory co-design journey, we are making visible the processes of our work so that they can be linked to future outcomes and related impact, and inform a wide range of patient co-led processes.

Lung cancer is the most commonly diagnosed cancer in Canada and is responsible for a quarter of all cancer-related deaths in the country. Screening for lung cancer using tools such as a CT scan can allow us to find lung cancers when they are still small and curable. People can receive a lung CT scan depending on how old they are and for how long they have smoked cigarettes. Certain groups of people, particularly those who have fewer resources such as time and money, and those who experience injustice because of who they are and how they look are less likely to participate in lung cancer screening. We can increase participation in lung cancer screening by educating healthcare providers on appropriate and timely ways to talk to patients about lung cancer screening. In this paper, we outline the steps of a patient-partnered study in which many different stakeholders such as patients, providers and policy-makers have come together with a goal to improve equity in access to lung cancer screening. We will do this by jointly creating an online learning module that will educate healthcare providers on how life experiences shape smoking behaviour and lung cancer risk. The module will also impart key skills on how to deliver care which is timely, appropriate and safe. Once the module is ready it will be freely available to all healthcare providers to support the fair and just delivery of lung cancer screening in the province of Ontario and elsewhere.

Amblyopia Elimination Project: Pediatric Medical Home-Based Community Vision Screening.

PURPOSE: To examine whether facilitating access to instrument-based screening equipment will increase the total number of high-quality, age-appropriate vision screenings provided to the preschool aged population. METHODS: The goal of the Naples Lions Amblyopia Elimination Project was to place a SPOT Vision Screener (Welch Allyn, Skaneateles Falls, NY) in every pediatric medical home using philanthropic dollars. Participating medical homes agreed to provide data on the number of children screened, number of referrals made, criteria for referral, and follow-up notes regarding examination outcomes. RESULTS: In 2012, only 4 of the 23 pediatric medical homes in Collier County were using instrument-based vision screening equipment. By 2017, 19 of the 25 pediatric medical homes (76%) used SPOT Vision Screeners. In 2017, 6,052 preschool children were screened in these 19 pediatric medial homes. CONCLUSIONS: The concept for this community-based philanthropic effort is original in its design and implementation and is a significant step forward in the goal to eliminate preventable permanent vision loss in children.
