Improving Antibiotic Resistant Infection Transmission Situational Awareness in Enclosed Facilities with a Novel Interface Design for Tactical Biosurveillance
The implementation of the Electronic Health Record to substantially improve the practice of medicine has not fully reached its projected potential partly due to many barriers to its adoption. There is growing evidence that one of the reasons for the delay in the adoption of EHR has been due to the negative impact of current EHRs on the clinician-patient interaction, clinician workflow and communications. This research studies the usability of the Electronic Health Record for clinicians involved in cardiac care by evaluating various clinician-patient interaction workflows. The aim of the study is to identify inefficiencies by examining the similarities and differences among various clinician-patient interaction workflows. This research is presented as “work in progress”
Patient Preferences for Authentication and Security: A Comparison Study of Younger and Older Patients
We examine authentication and security preferences of younger versus older patients in the healthcare domain. Previous research has investigated users\u27 perception of the acceptability of various forms of authentication in nonhealthcare domains, but not patients’ preferences. First, we developed an interactive prototype to test three authentication methods: passwords, pattern, and voice. Our results indicate that younger patients prefer passwords by a significant margin. Older patients indicated more mixed preferences. In addition, we evaluated the level of security patients desired for protection of health information compared to financial information. We found no difference based on age: both groups felt financial security is more important than health data security. The findings of this research can be used to improve and enhance usability of future PHRs and overall PHR usage by patients. While this study is specific to cardiology patients we believe the results are generalizable to all patients with chronic conditions
Amoebic liver abscess in northern Sri Lanka: first report of immunological and molecular confirmation of aetiology
Randomized Clinical Trial of High-Dose Rifampicin With or Without Levofloxacin Versus Standard of Care for Pediatric Tuberculous Meningitis: The TBM-KIDS Trial
Background. Pediatric tuberculous meningitis (TBM) commonly causes death or disability. In adults, high-dose rifampicin may reduce mortality. The role of fluoroquinolones remains unclear. There have been no antimicrobial treatment trials for pediatric TBM.
Methods. TBM-KIDS was a phase 2 open-label randomized trial among children with TBM in India and Malawi. Participants received isoniazid and pyrazinamide plus: (i) high-dose rifampicin (30Â mg/kg) and ethambutol (R30HZE, arm 1); (ii) high-dose rifampicin
and levofloxacin (R30HZL, arm 2); or (iii) standard-dose rifampicin and ethambutol (R15HZE, arm 3) for 8 weeks, followed by 10 months of standard treatment. Functional and neurocognitive outcomes were measured longitudinally using Modified Rankin Scale (MRS) and Mullen Scales of Early Learning (MSEL).
Results. Of 2487 children prescreened, 79 were screened and 37 enrolled. Median age was 72 months; 49%, 43%, and 8% had stage I, II, and III disease, respectively. Grade 3 or higher adverse events occurred in 58%, 55%, and 36% of children in arms 1, 2, and 3, with 1 death (arm 1) and 6 early treatment discontinuations (4 in arm 1, 1 each in arms 2 and 3). By week 8, all children recovered to MRS score of 0 or 1. Average MSEL scores were significantly better in arm 1 than arm 3 in fine motor, receptive language, and expressive language domains (P < .01).
Conclusions. In a pediatric TBM trial, functional outcomes were excellent overall. The trend toward higher frequency of adverse events but better neurocognitive outcomes in children receiving high-dose rifampicin requires confirmation in a larger trial.

COMPARISON AND ANALYSIS OF THE CLINICIAN-EHR INTERACTION WORKFLOWS

Combined drug medium with isoniazid and rifampicin for identification of multi-drug resistant Mycobacterium tuberculosis
A low-cost method of detecting multi-drug resistant Mycobacterium tuberculosis (MDR-TB) with the possibility
of quick adoption in a resource limited setting is urgently required. We conducted a study combining isoniazid and
rifampicin in a single LJ medium, to detect MDR-TB strains. Combined and individual drug media showed 100%
concordance for the detection of MDR-TB and susceptible strains by proportion method. Considering the results,
combined isoniazid and rifampicin containing medium could be considered for use in settings where the sole detection
of MDR-TB strains is justified
Fast track method for the identification of multi-drug resistant tuberculosis on direct clinical specimen using combined drug media
Objective
To combine isoniazid (INH) and rifampicin (RIF) in a single media to detect and evaluate multi-drug resistant Mycobacterium tuberculosis (MDR-TB) strains using clinical specimens by direct and indirect drug susceptibility testing (DST).
Methods
Drug susceptibility testing for INH and RIF using individual and combined drug media was performed by minimum inhibitory concentration (MIC) method on direct clinical specimens.
Results
The combined drug media showed complete concordance with individual drug media in the detection of MDR-TB by direct DST method and 89% efficiency with indirect DST method. Susceptibility results were available by 3 weeks after the receipt of clinical specimen using direct DST on combined drug media.
Conclusions
Combined drug media can be used as a fast track method in large scale studies warranting detection of MDR-TB
