Obstructive Sleep Apnea Screener

Diastolic Robotics Inc.
[ This app is no longer available for download ]

(V2.0.1 IS A RE-WRITE FOR iOS6+)

Obstructive Sleep Apnea Screener provides access to screening tools that identify patients suffering from obstructive sleep apnea.

Surgical patients with Obstructive Sleep Apnea (OSA) are more likely than non-OSA surgical patients to suffer post-operative complications. (See: Gupta et al. "Postoperative Complications in Patients With Obstructive Sleep Apnea Syndrome Undergoing Hip or Knee Replacement: A Case-Control Study" Mayo Clin Proc. 2001;76:897-905, and Liao et al. "Postoperative complications in patients with obstructive sleep apnea: a retrospective matched cohort study" Can J Anesth/J Can Anesth (2009) 56:819–828)

The Obstructive Sleep Apnea Screener (OSAS) provides four OSA screening tools including:
•The American Society of Anesthesiologists’ Checklist
•The Berlin questionnaire
•The STOP Questionnaire: Snoring, Tired, Observed breathing disruption, high blood Pressure
•The STOP-BANG questionnaire: comprised of the STOP Questionnaire with further questions for BMI, Age, Neck circumference and Gender.

The OSAS software eliminates the need for memorization of these tests and referral to textbooks or journals to administer the screens correctly. Users have access to these screens at their fingertips.

Using these screens, physicians can determine the general likelihood (low or high) of a patient suffering from OSA. This application will be particularly useful for anesthesiologists/anesthetists, surgeons and other care providers obtaining patient history prior to surgery, so that they may be better prepared to deal with complications if they arise.

Once data is input, the likelihood of OSA is recalculated for each category and questionnaire and the results are displayed at the bottom of the screen. Statements for categories within each test and for the overall result of the test are shown with highlighting according to the result:
•Category results will have either no background to indicate a normal, non-positive result, or they will have a yellow background to indicate that the patient is positive for that category.
•Overall results are color coded blue to indicate a low probability of OSA, or red to indicate that OSA is likely to be present in the patient according to the particular questionnaire.

WARNING: This software does not provide a diagnosis nor medical advice, but only a general likelihood (low or high) of Obstructive Sleep Apnea. The software is intended to be a convenience tool providing the screening tests in an accessible and portable format. The software is not intended to replace a physician's clinical judgement.

This software implements publically available screening tests from peer reviewed medical and scientific literature. The results echo the tests presented in the literature (see References below for the journal article citations noting the exact tests, their accuracy and details of the clinical testing). Diastolic Robotics Inc. can guarantee neither the accuracy of the tests nor the applicability of the tests to an individual patient. It is assumed that the user of the software is a physician who will use their clinical judgement, and knowledge of these screens to interpret the software's output.

What's new in version 2.0.1
Version 2.0.1 is a re-write of the App to function in iOS6 and beyond. Thank you to those who pointed out the App was not working on the newer OS. Thank you to everyone for your patience and our apologies to everyone for repairing it having taken so long. Version 1.0.1 should be downloaded for devices using operating systems pre-dating iOS6.

ADDED: email functionality: User may email data entered, test results and summaries.

UPDATED: User interface.

Screenshots for the new version 2.0.1 are shown for the 4.7", 5.5", 4" and iPad Pro. Screenshots for the original version 1.0.1 (to work with operating systems predating iOS6) are shown for the 3.5" and iPad.
Our verdict: Meh!
  • Obstructive Sleep Apnea Screener is a poorly rated app (1-star).
  • + It is currently 50% off its regular price.
  • + The app is also at the lowest price we've seen.
