OSA Screening Questionnaire for Sleep Disorder Diagnosis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for diagnosing and treating Obstructive Sleep Apnea (OSA) are cumbersome, expensive, and often ineffective, with a high rate of underdiagnosis and inadequate pharmacological solutions, leading to significant health issues and poor quality of life for affected individuals.
Innovation Solution
A practical and simple screening method that identifies symptoms such as daytime sleepiness, hypercaloric intake, and fragmented sleep, allowing for the co-administration of benzodiazepines and non-benzodiazepines with APAP treatment to alleviate adverse effects, and providing therapeutic indications for CPAP/APAP, BiPAP, and surgery, without the need for complex devices or chemical analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If complex diagnostic devices and chemical analysis are used for OSA diagnosis, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent uses a questionnaire that copies and translates clinical diagnostic criteria into patient-reportable symptoms. Instead of requiring complex polysomnography equipment, the invention creates a simplified copy of the diagnostic process that can be administered in any clinical setting, maintaining diagnostic utility while eliminating complex device requirements
Solution Approach 2:
The patent replaces mechanical and electronic diagnostic systems (polysomnography equipment, chemical analysis) with a paper-based or digital questionnaire system. The mechanical complexity of breath detection devices, oxygen saturation monitors, and EEG equipment is substituted with a straightforward symptom assessment tool that asks patients about their sleep patterns, breathing events, and daytime symptoms
2Adaptability or versatility
If current pharmacological treatments are used for OSA, then treatment coverage is improved, but harmful effects increase due to inadequate solutions
Solution Approach 1:
The patent enables patients to self-assess their OSA risk through the questionnaire and self-identify their need for further diagnostic evaluation or treatment. The screening tool empowers patients to take an active role in recognizing their own symptoms and seeking appropriate care, reducing reliance on pharmacological interventions for mild cases while ensuring timely referral for severe cases
Solution Approach 2:
The questionnaire provides immediate feedback to both patients and clinicians about the likelihood of OSA based on reported symptoms. This feedback mechanism allows for stratified treatment approaches where patients can be directed to appropriate levels of care (lifestyle modifications, CPAP therapy, or surgical evaluation) based on their screening results, avoiding unnecessary pharmacological treatment for those who would benefit from non-pharmacological interventions
3Ease of operation
If simple screening methods are used, then ease of operation is improved, but measurement precision deteriorates
Solution Approach 1:
The patent segments the OSA diagnostic process into distinct components: a preliminary screening questionnaire that identifies high-risk patients, followed by selective referral for polysomnography or home sleep apnea testing. This segmentation allows the simple questionnaire to be used universally while reserving complex testing for cases where it is most needed, maintaining both ease of operation and diagnostic precision
Solution Approach 2:
The patent creates a dynamic diagnostic pathway where the simplicity of the screening tool is matched with the complexity of subsequent diagnostic steps. The questionnaire serves as a dynamic filter that adapts the diagnostic process to each patient's needs - simple for low-risk patients and more comprehensive for high-risk patients - thereby maintaining overall system precision while preserving ease of initial operation

AI summary
A method for etiologic screening of Sleep Breathing Disorders, the most common, Obstructive Sleep Apnea, that includes 6 steps, as following: (1) identifying patients cognitive capabilities, irritability and level of tiredness/fatigue at awakening, (2) day hypersomnia, (3) repetitive hypercaloric food-intake during the day and/or night, (4) extreme fatigue/tiredness in the afternoon-night, (5) snoring (OSA), (6) sleep fragmentation, poor sleep quality, night anxiety, night sweating, insomnia, etc. . . . In case of OSA, the sole responsible for such disturbance is the intermittent hypoxia, in which case, performing all the necessary adherence plans for the APAP is indicated.
