Research Interest
Dr. Kristo previously first authored work on the Silent Upper Airways Resistance Syndrome (SUARS) which employed routine use of esophageal manometry, a gold standard but labor intense and seldom used diagnostic technique. The SUARS work stands as one of the most comprehensive assessments of incidence of SUARS within a patient population and helps explain sleepiness in the absence of obvious sleep disorders.
Dr. Kristo also first authored a paper validating the use of telemedicine in electronically transporting sleep study data by Internet thus expanding the access of sleep studies in remote areas with interpretation by trained physicians elsewhere. Internet transfer of sleep studies is now a routine part of daily sleep medicine clinical work within the field.
Dr. Kristo also co-authored efforts to assess home monitoring of patients on continuous positive airway pressure (CPAP) which proved that patients could be successfully followed on CPAP from remote locations with a home monitoring system. This finding is even relevant in metropolitan areas for those with transportation problems and difficulty in accessing the medical system in person.
Committee work in defining best patient care approaches in peri-operative care in sleep apneics, use of non-prescription remedies in sleep disorders, obstructive sleep apnea care, and prevalence of concomitant psychiatric disease in sleep clinic patients helps better define the sleep medicine field. Additionally this committee work directs care in areas without fully defined evidence based research to support medical actions required.
Clinical Interest
Dr. Kristo is most interested in providing high quality state-of-the-art medical care in Sleep Medicine for a broad and diverse patient population. This clinical interest manifests in credentialed laboratory operations and record patient accesses of overnight studies for years in succession. Additionally for example daily operational problems such as patients unable to sleep in a sleep laboratory are addressed with studies assessing effects of zolpidem on the quality of the sleep study while streamlining access with a team of providers lending to rapid release of results and meaningful quick clinical action on problems such as sleep apnea affecting patients’ safety and quality of life. Guideline papers and task force involvement lead to this same zeal for high quality care playing out on an international scale through committee work and guideline paper formulation.
Professional links formed through committee work promise additional efforts through teams of like minded physicians intent on providing the best possible diagnostic evaluation and treatment options for patients both locally and internationally.
Dr. Kristo serves as the Medical Director for the Montefiore and Monroeville Sleep Centers and as a Board of Directors Member for the American Academy of Sleep Medicine. Additionally, Dr. Kristo is involved in test question assessment for the American Board of Internal Medicine Pulmonary Disease exam.
