20Q: Hearing Aid Fitting and Big Data - Put Yourself in Context

---

1.  Sweden uses quality registries for: inspecting the quality of medical devices to ensure they pass regulatory standards storing information about medical interventions, outcomes and procedures on an individual level awarding healthcare workers with the best outcomes determining reimbursement rates for healthcare procedures

2.  Which of the following statements is true when comparing traditional hearing research to the use of big data to examine an issue? Hearing research generally uses a small number of subjects but the results are highly generalizable By using a small number of subjects in traditional hearing research it is easy to avoid selection bias Collecting data from clinics on a national level ensures there are a high number of subjects, but it may be harder to control certain variables as compared to laboratory studies used in traditional research Both approaches use the same means to answer research questions

3.  Sweden implemented a national quality register within hearing aid fitting in order to: increase competition among clinics and providers compare outcomes with other countries in Scandinavia to determine if audiology education in Sweden was adequate to help clinics to improve quality of service by providing a context where they could compare their outcomes

4.  An individual clinic that participates in the Swedish national registry for hearing aid fitting: can see how their performance ranks compared to other clinics can track progress over time can learn from other clinics who may have higher performance all of the above

5.  What variables are collected in the Swedish national registry within hearing aid fitting? Only objective data from the client's medical record (audiogram, hearing aid model, etc.) Only subjective information (patient survey) Both objective data (audiogram, hearing aid model, age, etc.) and subjective information (self-reported outcome survey) Hearing aid verification measures (probe mic) only

6.  The register looks at these 3 indicators: cost, soundfield threshold improvement, satisfaction of communication partners satisfaction/benefit, contact/information, function cost, soundfield threshold improvement, satisfaction satisfaction of communication partners, satisfaction of patient, cognitive function

7.  When looking at data between clinics, the author reports: there are little differences in performance between clinics there are large differences in performance between clinics only group data was collected so data between clinics could not be compared there are some differences in performance between clinics but they are not significant

8.  The data from the national registry show that clinics that are more focused on the information process: have lower revenue due to time spent that cannot be billed have lower patient satisfaction have higher values for patient satisfaction/benefit have higher in-the-drawer rates

9.  To look at hearing aid function, the register collects information about which four dimensions? uncomfortable loud sounds, feedback problems, sound quality, and communication in noise communication in quiet, audibility of soft sounds, hands-free operation, telecoil use daily wear time, use of volume control, use of multiple programs, Bluetooth compatibility ease of handling, daily wear time, audibility of soft sounds, satisfaction with own voice

10.  Which of the following statements is true based on the authors opinion/reflection? It is important to measure how hearing aids are used in daily life by clients if we are to continue to make improvements in benefit and technology While governments can benefit from the use of big data to look at healthcare trends, there is a lot of burden on individual practitioners to collect data and little benefit for them The use of big data violates clients' privacy with little benefits for the general public all of the above
