“…In 2005, a Spanish article stated “in addition to reducing testing costs, polygraphy has decentralized diagnosis from reference units by facilitating diagnosis at smaller centers that work with the reference units in a coordinated manner.” [14] The same article commented on the growing optimism regarding technological progress and the development of “equipment traditionally used by experts, which is now used by non-experts.” It has also been described in the literature that strategies developed within basic healthcare levels (general practitioners, nursing, low-complexity medical centers) are useful to enhance the diagnostic capacity of healthcare centers. [2], [3], [4], [5], [6], [7], [8], [9], [10], [11], [12], [13], [14], [15] It is worth mentioning that this type of coordination is not formally established in Argentina, though a pilot experience has been reported by two centers [16].…”

IntroductionObstructive sleep apnea syndrome (OSA) is diagnosed through polysomnography (PSG) or respiratory polygraphy (RP). Self-administered home-based RP using devices with data transmission could facilitate diagnosis in distant populations. The purpose of this work was to describe a telemedicine initiative using RP in four satellite outpatient care clinics (OCC) of Buenos Aires Hospital Británico Central (HBC).Materials and methodsOCC technicians were trained both in the use of RP. Raw signals were sent to HBC via intranet software for scoring and final report.ResultsDuring a 24-month 499 RP were performed in 499 patients: 303 men (60.7%) with the following characteristics (mean and standard deviation): valid time for manual analysis: 392.8 min (±100.1), AHI: 17.05 (±16.49 and percentile 25–75 [Pt]: 5–23) ev/hour, ODI (criterion 3%): 18.05 (±16.48 and Pt 25–75: 6–25) ev/hour, and time below 90% (T<90): 17.9% (±23.4 and Pt 25–75: 1–23). The distribution of diagnoses (absolute value and percentage) was: normal (66/13%), snoring (70/14%), mild (167/33.5%), moderate (110/22%), and severe (86/17.2%). Continuous positive airway pressure (CPAP) was indicated for 191 patients (38.6%). Twenty recordings (4%) were considered invalid and the RP had to be repeated.PSG at HBC was indicated in 60 (12.1%) cases (mild OSA or normal AHI with high ESS or cardiovascular disease).ConclusionsPhysicians were able to diagnosis OSA by doing portable respiratory polygraphy at distance. The remote diagnosis strategy presented short delays, safe data transmission, and low rate of missing data.

“…Various procedures already exist for screening patients with OSAHS, such as self‐ and interviewer‐administered questionnaires and electric devices that try to predict the presence of the syndrome based on monitoring one or a few physiological parameters 12,13 . Recently, with developments in technology, sleep medicine has shown great interest in single‐channel screening devices 14 . Among these, the pulse oximeter (PO) is a routinely used sleep apnea screener in Japan, and reportedly detects patients with high sensitivity and high specificity 13 .…”

In order to assess the usefulness of the SleepStrip (SS) in screening for obstructive sleep apneahypopnea syndrome (OSAHS) in Japanese settings, we measured its sensitivity and specificity against the reference standard diagnostic full-night polysomnography (FN-PSG) using a real-life timeline, and compared them to that of the simultaneously applied pulse oximeter (PO), a routinely used OSAHS screener in Japan. A total of 110 consecutive subjects with the symptoms of OSAHS underwent simultaneous SS and PO screening tests followed by a diagnostic FN-PSG within 7 weeks, a common time frame for accessing PSG in Japan. Data for 83 subjects were available for the final analysis. We analyzed both SS and PO output data as a standalone screening parameter, without combining it with other predictors for OSAHS. We obtained 71.9%, 68.3%, 57.1% and 63.2%, 61.0%, 39.3% sensitivities for SS and PO respectively, in order of mild, moderate, and severe cut-off points. The specificity values were 73.1%, 81.0%, and 87.3% for SS, while they were 92.3%, 100.0%, and 98.2% for PO in order of rising cut-off points. The SS demonstrated better screening performance with high compliance compared to the routinely used PO in our real-life timeline study; however, this performance is still lower than required to fully recommend SS as a large-scale standalone screener in the diagnostic pathway of OSAHS in Japan.
