In the past 5 yr, an increased incidence of tuberculosis has been noted in the United States. Simultaneously, the population infected with human immunodeficiency virus-type I (HIV-I) and the number of cases of acquired immunodeficiency syndrome (AIDS) have increased. Selected areas of the United States have also reported increases in the frequency of(More)
Informal caregivers, such as close friends and family, play an important role in a hospital patient’s care. Although CSCW researchers have shown the potential for social computing technologies to help patients and their caregivers manage chronic conditions and support health behavior change, few studies focus on caregivers’ role during a(More)
Patients going home after a hospitalization face many challenges. This transition period exposes patients to unnecessary risks related to inadequate preparation prior to leaving the hospital, potentially leading to errors and patient harm. Although patients engaging in self-management have better health outcomes and increased self-efficacy, little is known(More)
Patient engagement leads to better health outcomes and experiences of health care. However, existing patient engagement systems in the hospital environment focus on the passive receipt of information by patients rather than the active contribution of the patient or caregiver as a partner in their care. Through interviews with hospitalized patients and their(More)
BACKGROUND This study was designed to determine whether an automated hospital-based influenza vaccination screening program leveraging the electronic medical record (EMR) increases vaccination rates. METHODS We performed a retrospective cohort study of all children ≥6 months old admitted to medical, surgical, rehabilitation, or psychiatry services during(More)
Information seeking and synthesis are time consuming processes for physicians. Although systems have the potential to simplify these tasks, future improvements must be based on an understanding of how physicians perform these tasks during clinical prioritization. We enrolled 23 physicians in semi-structured focus groups discussing simulated inpatient(More)
Despite growing use of patient-facing technologies such as patient portals to address information needs for outpatients, we understand little about how patients manage information and use information technologies in an inpatient context. Based on hospital observations and responses to an online questionnaire from previously hospitalized patients and(More)
Involving patients in healthcare safety practices has long been an area of priority and importance. However, we still need to understand how patients perceive undesirable events during their hospital stay, and what role patients play in the prevention of these events. To address this gap, we surveyed pediatric inpatients and caregivers to understand their(More)
Although research has demonstrated improved outcomes for outpatients who receive peer support-such as through online health communities, support groups, and mentoring systems-hospitalized patients have few mechanisms to receive such valuable support. To explore the opportunities for a hospital-based peer support system, we administered a survey to 146(More)
One of the keys to any successful CPOE implementation is the development, deployment, and maintenance of well designed order sets that promote evidence based best practice. At Seattle Children's we implemented ambulatory CPOE in multiple subspecialty pediatric clinics. Using our previous experience with inpatient CPOE, we translated our order set process to(More)
