In Ireland, the herd prevalence of bovine tuberculosis has remained stable for several decades, and in common with several other countries, progress towards eradication has stalled. There is evidence in support of the potential role of infected badgers (Meles meles, a protected species) in bovine tuberculosis in Ireland and Britain. However, this evidence(More)
Design: Chart review was performed on a stratified random subset of all allergy alerts occurring during a 3-month period (August through October 2002) at a large academic hospital. Measurements: Factors that were measured were drug/allergy combinations that triggered alerts, frequency of specific override reasons, characteristics of ADEs, and completeness(More)
Design: Mailed survey to a stratified random sample of all medical practices in Massachusetts in 2005, with one physician per practice randomly selected for survey. Measurements: EHR adoption rates. Results: The response rate was 71% (1345/1884). Overall, while 45% of physicians were using an EHR, EHRs were present in only 23% of practices. In multivariate(More)
OBJECTIVE We sought to assess the epidemiology of medication errors (MEs) and adverse drug events (ADEs) in a psychiatric hospital. METHODS We conducted a 6-month prospective observational study in a 172-bed academic psychiatric hospital. Errors and ADEs were found by way of chart review, staff reports and pharmacy intervention reports. Physicians rated(More)
IMPORTANCE Because effective interventions to reduce hospital readmissions are often expensive to implement, a score to predict potentially avoidable readmissions may help target the patients most likely to benefit. OBJECTIVE To derive and internally validate a prediction model for potentially avoidable 30-day hospital readmissions in medical patients(More)
BACKGROUND Web-based personal health records (PHRs) have been advocated as a means to improve type 2 diabetes mellitus (DM) care. However, few Web-based systems are linked directly to the electronic medical record (EMR) used by physicians. METHODS We randomized 11 primary care practices. Intervention practices received access to a DM-specific PHR that(More)
During the period March 1996-July 1997, 417 heads of Awassi sheep slaughtered at the Irbid Abattoir (northern Jordan) were examined for the three larval instars (L1, L2 and L3) of Oestrus ovis. Of the 417 heads, 242 (58%) were infested with O. ovis larvae. Larval numbers were highly aggregated. The lowest number of larvae and the lower quartile were both(More)
BACKGROUND Personal health records (PHRs) have emerged as an important tool with which patients can electronically communicate with their doctors and doctor's offices. However, there is a lack of theoretical and empirical research on how patients perceive the PHR and the differences in perceptions between users and non-users of the PHR. OBJECTIVE To apply(More)
We examined the effect of varying levels of badger population control on the prevalence of Mycobacterium bovis infection in badgers in four counties of Ireland. In the 'Removal' and 'Buffer' areas, proactive culling was conducted to substantially reduce and subsequently maintain badger populations at a low level for five years. In the 'Reference' areas,(More)
BACKGROUND Personal health records (PHRs) offer the potential to improve the patient experience and the quality of patient care. However, the "digital divide," the population-level gap in Internet and computer access, may prevent certain groups from accessing the PHR. METHODS We conducted a cross-sectional analysis of a PHR within a northeastern health(More)
