Misha Amoils, Kay W. Chang, Olga Saynina, Paul H. Wise, Anita Honkanen
Journal of the American Medical Association (JAMA) Otolaryngology -- Head and Neck Surgery, 2016 April 1, 2016

Importance

A large-scale review is needed to characterize the rates of airway, respiratory, and cardiovascular complications after pediatric tonsillectomy and adenoidectomy (T&A) for inpatient and ambulatory cohorts.

Objective

To identify risk factors for postoperative complications stratified by age and operative facility type among children undergoing T&A.

Impact of Including Readmissions for Qualifying Events in the Patient Safety Indicators

Sheryl M. Davies, Olga Saynina, Laurence C. Baker, Kathryn M. McDonald
American Journal of Medical Quality, 2014 January 1, 2014

Abstract:  The Agency for Healthcare Research and Quality Patient Safety Indicators (PSIs) do not capture complications arising after discharge. This study sought to quantify the bias related to omission of readmissions for PSI-qualifying conditions. Using 2000-2009 California Office of Statewide Health Planning and Development Patient Discharge Data, the study team examined the change in PSI rates when including readmissions in the numerator, hospitals performing in the extreme deciles, and longitudinal performance.

Health Services Research, 2013 June 6, 2013

Objective. To quantify the differential impact on hospital performance of three readmission metrics: all-cause readmission (ACR), 3M Potential Preventable Readmission (PPR), and Centers for Medicare and Medicaid 30-day readmission (CMS).

Disparities in Trauma Center Access Despite Increasing Utilization: Data From California, 1999 to 2006

Hsia RY, Wang E, Torres H, Olga Saynina, Paul Wise
Journal of Trauma, 2009 December 1, 2009

Background: Although efforts have been made to address disparities in access to trauma care in the past decade, there is little evidence to show if utilization has changed. We use patient-level data to describe the changes in utilization of trauma centers (TCs) in an 8-year period in California.

Methods: We analyzed all statewide trauma admissions (n = 752,706) using the California Office of Statewide Health Planning and Discharge Patient Discharge Database from the period of 1999 to 2006, and determined the trends in admissions and place of care.

Inequality in Treatment Use Among Elderly Patients with Acute Myocardial Infarction: USA, Belgium and Quebec

Perelman J, Amir Shmueli, Kathryn M. McDonald, Louise Pilote, Olga Saynina, Closon MC, Investigators TT
BMC Health Services Research, 2009 July 30, 2009

BACKGROUND: Previous research has provided evidence that socioeconomic status has an impact on invasive treatments use after acute myocardial infarction. In this paper, we compare the socioeconomic inequality in the use of high-technology diagnosis and treatment after acute myocardial infarction between the US, Quebec and Belgium paying special attention to financial incentives and regulations as explanatory factors.

Systematic Review: The Effects of Growth Hormone on Athletic Performance

Hau Liu, Dena M. Bravata, Ingram Olkin, Roberts B, Eran Bendavid, Olga Saynina, Salpeter SR, Alan Garber, Hoffman AR
Annals of Internal Medicine, 2008 March 17, 2008

BACKGROUND: Human growth hormone is reportedly used to enhance athletic performance, although its safety and efficacy for this purpose are poorly understood. PURPOSE: To evaluate evidence about the effects of growth hormone on athletic performance in physically fit, young individuals.

DATA SOURCES: MEDLINE, EMBASE, SPORTDiscus, and Cochrane Collaboration databases were searched for English-language studies published between January 1966 and October 2007.
