Utilization of radial artery access for percutaneous coronary intervention for ST-segment elevation myocardial infarction in New York.

Objectives: This study sought to determine the utilization and outcomes for radial access for percutaneous coronary intervention (PCI) for ST-segment elevation acute myocardial infarction (STEMI) in common practice.

Background: Radial access for PCI has been studied considerably, but mostly in clinical trials.

Methods: All patients undergoing PCI for STEMI in 2009 to 2010 in New York were studied to determine the frequency and the patient-level predictors of radial access.

The New York State risk score for predicting in-hospital/30-day mortality following percutaneous coronary intervention.

Objectives: This study sought to develop a percutaneous coronary intervention (PCI) risk score for in-hospital/30-day mortality.

Background: Risk scores are simplified linear scores that provide clinicians with quick estimates of patients' short-term mortality rates for informed consent and to determine the appropriate intervention. Earlier PCI risk scores were based on in-hospital mortality.

The New York risk score for in-hospital and 30-day mortality for coronary artery bypass graft surgery.

Background: Simplified risk scores for coronary artery bypass graft surgery are frequently in lieu of more complicated statistical models and are valuable for informed consent and choice of intervention. Previous risk scores have been based on in-hospital mortality, but a substantial number of patients die within 30 days of the procedure. These deaths should also be accounted for, so we have developed a risk score based on in-hospital and 30-day mortality.

Predicting trauma inpatient mortality in an administrative database: an investigation of survival risk ratios using New York data.

Background: A precise and unbiased measure of injury severity, calculable from administrative data sets, is needed for population-based studies.

Methods: The 2001 Nationwide Inpatient Sample was used to calculate independent and traditional survival risk ratios. Logistic regression models predicting survival for New York State's Statewide Planning and Research Cooperative System 2003 inpatients (117,630 records) were constructed for both types of survival risk ratios.

Physiologic trauma triage criteria in adult trauma patients: are they effective in saving lives by transporting patients to trauma centers?

Background: Trauma triage criteria have been in place for many years and were updated in 1999 by the American College of Surgeons. We are unaware of any studies that have directly examined the ability of these criteria to reduce short-term mortality by transporting patients to trauma centers rather than to noncenters.

Study Design: Retrospective observational cohort study of adult patients meeting physiologic triage criteria who were transported to 9 regional (Level I) trauma centers, 21 area (Level II) trauma centers, and 119 noncenters in New York in 1996 to 1998.

A comparison among the abilities of various injury severity measures to predict mortality with and without accompanying physiologic information.

Background: A few recent studies have compared the abilities of different injury severity measures to predict inpatient mortality. This study extended previous studies in that it used a registry with noncenters as well as centers, and examined the relative marginal abilities of competing severity measures to predict mortality when physiologic data also are available.

Methods: Several methods for assessing injury severity of trauma patients were compared in terms of their ability to predict mortality with and without the addition of additional demographic and physiologic information using logistic regression models.

Elderly trauma inpatients in New York state: 1994-1998.

Background: The aging of the population in the United States has led to an increase in geriatric trauma. This study aimed to examine the characteristics and outcomes of geriatric trauma patients in New York State.

Methods: Four groups of elderly trauma patients (ages 40-64, 65-74, 75-84, and 85+ years) were contrasted with younger adults ages 13 to 39 years with respect to mechanism of injury, discharge disposition, hospital length of stay, comorbidities, and type of hospital in which they were treated.

Severity of injury and mortality associated with pediatric blunt injuries: hospitals with pediatric intensive care units versus other hospitals.

Objective: To a) compare in-hospital mortality rates for pediatric (age <13 yrs) patients with blunt injuries in the New York State Trauma Registry based on hospital type (dedicated pediatric intensive care unit [PICU] and designated trauma centers and noncenters that do not have a dedicated PICU) for the purpose of determining whether there is a reduction in mortality at a specialty hospital and b) determine the extent to which high-risk patients are admitted to specialty hospitals.

Data Source: Inpatient data for the years 1994-1998 in the New York State Trauma Registry.

Study Selection: A total of 8,180 pediatric inpatients who suffered blunt injury were selected to examine where patients were treated (PICU, regional trauma center without PICU, area trauma center without PICU, or noncenter without PICU) as a function of injury severity.
