The review, led by Mana Alshahrani of King Fahd Medical City, Alfaisal University College of Medicine, and the Ministry of Health, documents a system expanding at remarkable speed from a very low base. Active Ministry of Health sleep centers grew from five to eight over the study period. Polysomnography bed capacity—the number of beds available for overnight, attended sleep studies—rose from 8 to 20, a compound annual growth rate of 35.7 percent. Annual sleep-study output climbed from 2,290 to 5,851 studies, growing at 36.7 percent per year. Adjusted for population, output rose from 7.1 to 16.6 studies per 100,000 people, a 134 percent increase.

Those efficiency gains are real, the authors argue, because output grew faster than infrastructure alone would predict. Their statistical analysis found that the number of polysomnography beds correlated strongly with in-lab study output (Spearman rho of 0.86), and home sleep apnea testing device counts correlated with home-study output (rho of 0.83), indicating that installed capacity is being used rather than left idle. But the absolute throughput of 16.6 studies per 100,000 remains an order of magnitude below the several hundred per 100,000 per year typical of mature programs in high-income countries, so growth from a low base should not be mistaken for adequacy.

The disease burden driving this expansion is substantial. Saudi population-based studies place adult obstructive sleep apnea prevalence between 8.8 and 12.8 percent, with rates above 30 percent among middle-aged men and among adults with obesity, type 2 diabetes, or resistant hypertension. Untreated obstructive sleep apnea carries roughly a two- to threefold higher risk of stroke, heart failure, atrial fibrillation, resistant hypertension, and motor-vehicle crashes. Saudi data attribute roughly 11 to 12 percent of road traffic accidents to driver sleepiness, with up to 30 percent of near-miss events similarly attributable. Yet public awareness has not kept pace: in the largest Saudi survey to date, only 12.9 percent of 16,662 adults demonstrated good knowledge of the condition.

To estimate how far current capacity falls short, the team built a capacity-to-demand model. Under the base case—assuming 12 percent adult obstructive sleep apnea prevalence, an adult population fraction of 65 percent, and an annual diagnostic-capture target of 5 percent of the prevalent pool—the estimated Ministry of Health demand is approximately 137,670 studies per year. Actual 2025 output of 5,851 studies represents just 4.2 percent of that estimate. Sensitivity analyses, spanning a conservative scenario with lower prevalence and capture rates to an expansive one with higher values, produced a coverage range of roughly 3 to 11 percent, but the order of magnitude of the gap remained unchanged across all scenarios. Even when non-Ministry facilities are included, all-sector coverage is unlikely to exceed roughly 18 to 22 percent of estimated need, leaving a structural shortfall on the order of 100,000 studies per year.

The workforce emerges as the binding constraint rather than physical infrastructure. The Ministry network employed 15 sleep physicians in 2025—12 adult and three pediatric—serving an attributed population of about 35.3 million, which corresponds to 0.42 sleep physicians per million. Workforce growth, at a compound annual rate of 14.9 percent, lagged well behind the expansion of beds and equipment. The estimated all-sector Saudi ratio of approximately 0.10 sleep physicians per 100,000 people sits far below reported figures for the United States (1.7), Germany (1.9), Canada (1.3), and Japan (0.42). Several clusters operate with a single sleep physician, a continuity risk for the service. The fellowship pipeline, now six Saudi Commission for Health Specialties-accredited programs producing about 15 graduates every two years, remains below the estimated need of 50 to 70 net new sleep physicians by 2030 to reach a density of two per million.

Access is also strikingly uneven. In 2025, polysomnography waiting times across the eight Ministry centers ranged from 7 days in Hail to 479 days in the Eastern Province—a 68-fold spread that the authors attribute to geography rather than clinical acuity. No national triage tool currently exists to expedite high-risk patients such as commercial drivers, patients with severe nocturnal hypoxemia, or children with obstructive sleep apnea and growth failure. Meanwhile, the CPAP backlog tells a story of diagnosis decoupled from treatment: in 2025, 326 CPAP devices were prescribed against a documented waiting list of 2,393 patients, a backlog-to-fulfillment ratio of roughly 7 to 1. Because untreated obstructive sleep apnea carries measurable cardiovascular, metabolic, and road-safety harms, the authors describe this backlog as deferred clinical harm rather than a purely administrative queue.

The service model itself remains narrow. The Ministry network is functionally an obstructive sleep apnea service: cognitive behavioral therapy for insomnia, the guideline-endorsed first-line treatment for chronic insomnia, is not represented in operational reporting, and no behavioral sleep-medicine providers are recorded in the workforce. Restless legs syndrome, parasomnias, circadian rhythm disorders, and obesity hypoventilation syndrome are similarly underdeveloped. Pediatric sleep medicine, by contrast, emerged as a defined service line in 2025, with 557 pediatric in-lab polysomnography studies accounting for 17 percent of in-lab activity—within the 10 to 20 percent range reported internationally. The dataset also captures a rising national narcolepsy caseload, with 141 cases under follow-up in 2025.

Against these gaps, the Ministry’s National Sleep Medicine Program, launched in 2024, has delivered a coordinated set of milestones organized around eight pillars. These include a national master plan anchored to the Health Sector Transformation Program; a readiness manual distributed to all clusters; formal instructions to establish sleep centers in five previously under-served regions (Jeddah, Al-Jouf, Jazan, Asir, and Tabuk); a specialized sleep clinic within the Virtual Health Hospital for remote consultations; and the first Saudi-specific accreditation framework for sleep medicine, under which eight centers received formal classification certificates in 2025—two at Tier A and six at Tier B. The program also produced public- and private-sector regulatory frameworks, bilingual public-awareness campaigns, official World Sleep Day recognition from the World Sleep Society in March 2024, a traffic-safety proposal recommending systematic screening of commercial drivers, and a national training workshop in Riyadh in December 2024.

The authors’ prescription for the next phase is a shift from infrastructure expansion alone to a learning health-system model. Their ten recommendations include a mandatory national sleep registry capturing coded diagnoses, apnea-hypopnea index severity, comorbidities, and 30-day and 90-day CPAP adherence; a unified national referral and triage pathway routing uncomplicated cases to home testing while reserving in-lab polysomnography for complex presentations; an explicit workforce target of at least two sleep physicians per million population by 2030; centralized positive airway pressure procurement and adherence support commissioned as a treatment program rather than isolated device purchasing; and integration of sleep medicine with chronic-disease, occupational-health, and road-safety programs. Emerging technologies—artificial intelligence for automated polysomnography scoring, consumer wearables, digital biomarkers, and cloud-based CPAP telemonitoring—could relieve the physician-scoring bottleneck and extend screening into primary care, though the authors caution that models require local validation and that digital equity must be safeguarded so technology narrows rather than widens regional disparities. If those pieces come together, the review concludes, sleep medicine could mature from an emerging, capacity-constrained service into a practical contributor to Vision 2030 goals for access, prevention, value, and population health.
