BackgroundMulti-drug resistant tuberculosis patients in resource-poor settings experience large delays in starting appropriate treatment and may not be monitored appropriately due to an overburdened laboratory system, delays in communication of results, and missing or error-prone laboratory data. The objective of this paper is to describe an electronic laboratory information system implemented to alleviate these problems and its expanding use by the Peruvian public sector, as well as examine… 

Developing, implementing, and evaluating tuberculosis laboratory information systems for resource-poor settings

E-Chasqui, a web-based system developed to provide electronic communication and reporting of TB laboratory information to health care personnel within institutions with internet, resulted in significantly less time to receipt of test results and a 98% reduction of results that never arrived.


A web-based laboratory information system with specimen bar code labelling functionality has been deployed in KNH CCC and key lessons learnt for new system acceptability is that iterative discussions with all stakeholders followed by training sessions to all laboratory personnel are critical.

Reducing Communication Delays and Improving Quality of Care with a Tuberculosis Laboratory Information System in Resource Poor Environments: A Cluster Randomized Controlled Trial

The eChasqui system reduced the time to communicate results between laboratories and HCs and time to culture conversion, and is now used in over 259 HCs covering 4.1 million people.

Adaptation of a web-based, open source electronic medical record system platform to support a large study of tuberculosis epidemiology

The information system served the study objectives well despite requiring some significant adaptations mid-stream, and OpenMRS can be an effective research data system in resource poor environments.

Medical information systems: A foundation for healthcare technologies in developing countries

The systems described above illustrate the advantages of implementing healthcare technologies within larger collaborations that improve the overall public health infrastructure and the creation of long-term relationships to build infrastructure and solving systemic problems to provide health care can be beneficial to both the patients and the projects involved.

Impact of the Implementation of Laboratory Information System (WWDISA) on Timely Provision of HIV-1 Viral Load Results in a Rural Area, Inhambane, Mozambique

The WWDISA module has been shown to be effective in reducing the TAT, although a stable internet connection and accurate data entry are essential to make the system functional.

Full impact of laboratory information system requires direct use by clinical staff: cluster randomized controlled trial

Only point- of-care HCs with direct access to the e-Chasqui information system had reduced communication times and fewer results with delays of >2 months, suggesting that health establishments should have point-of-care access to reap the benefits of electronic laboratory reporting.

Improving the management and security of COVID 19 diagnostic test data with a digital platform in resource-limited settings: The case of PlaCARD in Cameroon

PlaCARD has demonstrated that it can be used as a LIMS for managing and securing test data during an outbreak, and has strengthened COVID 19 surveillance capabilities in Cameroon.

Report errors to the laboratory using e-Chasqui promoted continuous quality improvement and reduced the number of missing laboratory results at point-of-care health centers.


The purpose of this study was to analyse the tracking systems used to identify patients with tuberculosis who missed a clinic appointment at primary health care facilities in Waterberg District and found that nurses were unaware of the true defaulter rate in their facilities and did not implement relevant intervention strategies to recall patients.



Informatics tools to monitor progress and outcomes of patients with drug resistant tuberculosis in Peru

A web-based medical record system deployed in Peru to support the management of MDR-TB is argued to be an important component for successful implementation of complex health interventions in resource poor areas.

Evaluating the impact and costs of deploying an electronic medical record system to support TB treatment in Peru

The types of evaluations that have been performed on the PIH-EMR to assess its impact on patient care, reporting, logistics and observational research are described and it is proposed that additional data of this sort is valuable in assessing medical information systems especially in resource poor areas.

Experience in Implementing the OpenMRS Medical Record System to Support HIV Treatment in Rwanda

The design and implementation of a new medical record architecture to support an HIV treatment program in rural Rwanda is described and extensions to improve the support for the clinic are developed.

The total TAT, from initial sputum specimen to diagnosis and appropriate treatment, was 5 months, almost twice as long as the bacteriological procedures per se.

PHLIS: an electronic system for reporting public health data from remote sites.

The Public Health Laboratory Information System (PHLIS), a PC-based electronic reporting system for entering, editing, and analyzing data locally and for transmitting data electronically to other state or federal offices, is developed.

Electronic reporting improves timeliness and completeness of infectious disease notification, The Netherlands, 2003.

It is compared the timeliness of infectious diseases reported by the conventional paper-based system in 2001 with those reported by OSIRIS in 2003, and the significance of proportions of completed data fields in each system is determined.

Electronic reporting improves timeliness and completeness of infectious disease notification, The Netherlands, 2003.

The benefits of electronic reporting of infectious disease surveillance data in terms of improved timeliness and completeness are documents.

An information system and medical record to support HIV treatment in rural Haiti

The authors describe how they set up a web based medical record system linking remote areas in rural Haiti and how it is used to track clinical outcomes, laboratory tests, and drug supplies and to create reports for funding agencies.

The Lilongwe Central Hospital Patient Management Information System: A Success in Computer-Based Order Entry Where One Might Least Expect It

A pilot project in the pediatric department of the Lilongwe Central Hospital in Malawi, Africa has demonstrated that computer-based order entry has a greater potential to improve patient care in developing than in developed countries.

Reducing the Frequency of Errors in Medicine Using Information Technology

Appropriate increases in the use of information technology in health care— especially the introduction of clinical decision support and better linkages in and among systems, resulting in process simplification—could result in substantial improvement in patient safety.
