Previous Research
Anticipation of Monetary Gain but Not Loss in Healthy Older Adults in Nature Neuroscience (2007)
Citation: Samanez-Larkin, G. R., Gibbs, S. E., Khanna, K., Nielsen, L., Carstensen, L. L., & Knutson, B. (2007). Anticipation of monetary gain but not loss in healthy older adults. Nature Neuroscience, 10(6), 787-791.
Abstract: Although global declines in structure have been documented in the aging human brain, little is known about the functional integrity of the striatum and prefrontal cortex in older adults during incentive processing. We used event-related functional magnetic resonance imaging to determine whether younger and older adults differed in both self-reported and neural responsiveness to anticipated monetary gains and losses. The present study provides evidence for intact striatal and insular activation during gain anticipation with age, but shows a relative reduction in activation during loss anticipation. These findings suggest that there is an asymmetry in the processing of gains and losses in older adults that may have implications for decision-making.
Exploring Relationships Between Hospital Patient Safety Culture and Adverse Events (2010)
Citation: Mardon, R. E., Khanna, K., Sorra, J., Dyer, N., & Famolaro, T. (2010). Exploring relationships between hospital patient safety culture and adverse events. Journal of Patient Safety, 6(4), 226-232.
Summary: This exploratory study examined relationships between the Agency for Healthcare Research and Quality's (AHRQ) Hospital Survey of Patient Safety Culture and rates of in-hospital complications and adverse events as measured by AHRQ Patient Safety Indicators (PSIs). We found that hospitals with a more positive patient safety culture scores had lower rates of in-hospital complications or adverse events as measured by PSIs, controlling for hospital bed size and ownership.
Exploring Relationships Between Patient Safety Culture and Patients’ Assessments of Hospital Care (2012)
Citation: Sorra, J., Khanna, K., Dyer, N., Mardon, R., & Famolaro, T. (2012). Exploring relationships between patient safety culture and patients’ assessments of hospital care. Journal of Patient Safety, 8(3), 131-139.
Summary: This study’s purpose was to examine relationships among two Agency for Healthcare Research and Quality measures of hospital patient safety and quality, which reflect different perspectives on hospital performance: the Hospital Survey on Patient Safety Culture — a survey of hospital employees — and the Consumer Assessment of Healthcare Providers and Systems (CAHPS) Hospital Survey — a survey of the experiences of adult inpatients with hospital care and services. Using regression analysis, we found that 12 of 15 safety culture measures were positively related to the CAHPS composite average score after controlling for bed size and ownership, indicating that hospitals where staff have more positive perceptions of patient safety culture tend to have more positive assessments of care from patients.
