- ItemDevelopment, implementation and preliminary study of a PDA-based tuberculosis result collection system.(2007-01-22) Blaya, Joaquin; Fraser, Hamish S FPartners In Health PIH and its sister organization in Lima Peru Socios En Salud SES treat a majority of multidrug resistant tuberculosis MDR TB patients in Peru in conjunction with the Peruvian National TB Program NTP Monthly bacteriology tests which must be collected from health establishments located across this major city are an integral part of this treatment Currently a SES employee visits each health establishment to collect this information by hand process it and type it into an electronic medical record system PIH EMR In this paper we describe the development and implementation of a personal digital assistant PDA based electronic system to collect verify and upload monthly bacteriology data into the PIH EMR After an initial implementation period we performed a pilot study to test the use of this system We completed a baseline assessment in two health districts and then implemented the electronic system in one of the districts while the control site continued to use the paper based system during the same period The PDA based system had a processing time of 6 2 days significantly lower than measurements for both the baseline 54 8 and control sites 64 4 both pUnder0 0001 It was also able to reduce the frequency of discrepancy from 10 1 to 2 8 pUnder0 0001 and receive positive feedback from the users Finally the system s cost would be recuperated in three months from time savings due to increased work efficiency This system will be the subject of a larger study to determine its impact on delays errors and costs
- ItemEvaluating the impact and costs of deploying an electronic medical record system to support TB treatment in Peru.(2007-01-22) Fraser, Hamish S F; Blaya, Joaquin; Choi, Sharon S; Bonilla, Cesar; Jazayeri, DariusThe PIH EMR is a Web based electronic medical record that has been in operation for over four years in Peru supporting the treatment of drug resistant TB We describe here the types of evaluations that have been performed on the EMR to assess its impact on patient care reporting logistics and observational research Formal studies have been performed on components for drug order entry drug requirements prediction tools and the use of PDAs to collect bacteriology data In addition less formal data on the use of the EMR for reporting and research are reviewed Experience and insights from porting the PIH EMR to the Philippines and modifying it to support HIV treatment in Haiti and Rwanda are discussed We propose that additional data of this sort is valuable in assessing medical information systems especially in resource poor areas
- ItemImplementing medical information systems in developing countries, what works and what doesn't.(2011-02-24) Fraser, Hamish Sf; Blaya, JoaquinGlobal Health Informatics is an emerging field as demonstrated by several substantial and widely used electronic medical record EMR systems along with the emergence of mobile based or mhealth systems We describe here many of the practical lessons we have learned from implementing systems in a wide range of challenging environments over the last decade Some requirements like data backups skilled staff and local leadership are universally important Others such as limited power poor network access and distributed populations require different designs and strategies in resource poor environments
