Accurate and accessible diagnosis of sleep disorders remains a clinical challenge, often limited by the resource intensity and patient burden of in-laboratory polysomnography. Emerging technologies, including artificial intelligence, wearable devices, and advanced sensors, are poised to decentralise and streamline sleep diagnostics, offering continuous monitoring and earlier intervention across the care continuum.
- The Pivot Sleep diagnostics are shifting from episodic, in-lab testing to continuous, home-based monitoring using AI and sensor technology.
- The Data While specific comparative data is nascent, these technologies aim to improve diagnostic yield and patient adherence by reducing logistical barriers.
- The Action Clinicians should prepare for an increased integration of remote monitoring data into diagnostic algorithms and treatment pathways for sleep disorders.
Traditional sleep disorder diagnosis relies heavily on polysomnography (PSG), a multi-channel recording conducted in a sleep laboratory.1 This method provides comprehensive data on sleep stages, respiratory effort, cardiac activity, and limb movements.1 However, PSG is resource-intensive, requiring specialised equipment, trained technicians, and an overnight stay, which can be inconvenient and costly for patients.2 The logistical barriers associated with PSG often lead to diagnostic delays and underdiagnosis of prevalent conditions such as obstructive sleep apnoea (OSA) and insomnia.3
Next-Generation Technologies in Sleep Diagnostics
The ATS 2026 conference will highlight advancements in next-generation sleep diagnostics, focusing on technologies that aim to overcome the limitations of conventional PSG. These innovations include the integration of artificial intelligence (AI), wearable devices, and advanced sensor technologies.4
Wearable Devices and Sensors: Consumer-grade wearables, such as smartwatches and rings, are increasingly incorporating sensors capable of collecting physiological data relevant to sleep. These include photoplethysmography (PPG) for heart rate and oxygen saturation, accelerometers for actigraphy, and sometimes electrodermal activity sensors.5 Medical-grade wearable sensors are also under development, offering enhanced accuracy and validation for clinical use. These devices enable continuous, unobtrusive monitoring in the patient's natural sleep environment, potentially capturing sleep patterns over multiple nights, which can provide a more representative picture than a single night in a lab.6
Artificial Intelligence and Machine Learning: AI algorithms are being developed to process the vast amounts of data generated by wearables and other sensors. These algorithms can identify sleep stages, detect respiratory events, and characterise sleep architecture with increasing accuracy.7 For example, AI models trained on large PSG datasets can analyse single-channel electroencephalography (EEG) or even non-EEG signals (like heart rate variability and actigraphy) to infer sleep stages, potentially simplifying the diagnostic process.8 AI also holds promise for predicting treatment response and personalising interventions based on individual sleep phenotypes.9
Transformative Technologies Across the Care Continuum: The integration of these technologies is expected to transform the entire sleep care continuum. In primary care, simplified screening tools incorporating wearable data and AI analysis could facilitate earlier identification of individuals at risk for sleep disorders.10 For specialists, these tools could provide longitudinal data, allowing for more nuanced diagnosis and monitoring of treatment efficacy.11 Remote patient monitoring platforms, leveraging these technologies, could also support virtual consultations and reduce the need for in-person visits, improving access to care, particularly in underserved areas.12
While the potential benefits are substantial, several challenges remain. Standardisation of data collection and interpretation across different devices is critical.13 Regulatory pathways for medical-grade wearables and AI algorithms are still evolving.14 Furthermore, ensuring data privacy and security, as well as addressing potential biases in AI algorithms, are essential considerations for widespread clinical adoption.15 Validation studies comparing the diagnostic accuracy and clinical utility of these next-generation tools against established PSG are ongoing and will be crucial for their integration into clinical guidelines.16
The shift towards AI-driven, wearable-based sleep diagnostics represents a significant departure from the current paradigm, which has long been bottlenecked by the logistical demands of in-laboratory polysomnography. Clinicians, particularly those in primary care, will increasingly encounter patients presenting with data from consumer wearables, necessitating a new skillset for interpreting these metrics and discerning their clinical relevance. The challenge will be to integrate these novel data streams into existing diagnostic algorithms without over-diagnosing or mismanaging conditions based on unvalidated information. Guideline bodies like the American Academy of Sleep Medicine will need to rapidly develop frameworks for the appropriate use and interpretation of these technologies, ensuring that diagnostic accuracy is not sacrificed for convenience.
For patients, the promise of easier access to diagnosis and continuous monitoring is compelling. The ability to track sleep patterns in their natural environment, without the disruption of a sleep lab, could significantly improve adherence to diagnostic pathways and treatment regimens. However, the proliferation of consumer devices also raises concerns about data literacy and the potential for patients to self-diagnose or misinterpret their own sleep data, leading to unnecessary anxiety or inappropriate self-treatment. Industry players, from device manufacturers to AI developers, must prioritise rigorous clinical validation and transparent reporting of performance metrics to build trust within the medical community and ensure these tools genuinely enhance patient care, rather than merely adding noise to an already complex diagnostic landscape.
The economic implications are also considerable. Decentralised diagnostics could reduce healthcare costs associated with in-lab PSG, but this must be balanced against the cost of new devices, software subscriptions, and the infrastructure required to manage and interpret the influx of data. Payers will need to establish clear reimbursement policies for these emerging technologies, which will likely hinge on robust evidence demonstrating improved patient outcomes and cost-effectiveness. The ATS 2026 discussion underscores that while the technological capability is rapidly advancing, the clinical and economic integration will require careful, evidence-based navigation to realise the full transformative potential of next-generation sleep diagnostics.
