Human factors for capacity building: lessons learned from the OpenMRS implementers network.

OBJECTIVES: The overall objective of this project was to investigate ways to strengthen the OpenMRS community by (i) developing capacity and implementing a network focusing specifically on the needs of OpenMRS implementers, (ii) strengthening community-driven aspects of OpenMRS and providing a dedicated forum for implementation-specific issues, and; (iii) providing regional support for OpenMRS implementations as well as mentorship and training. METHODS: The methods used included (i) face-to-face networking using meetings and workshops; (ii) online collaboration tools, peer support and mentorship programmes; (iii) capacity and community development programmes, and; (iv) community outreach programmes. RESULTS: The community-driven approach, combined with a few simple interventions, has been a key factor in the growth and success of the OpenMRS Implementers Network. It has contributed to implementations in at least twenty-three different countries using basic online tools; and provided mentorship and peer support through an annual meeting, workshops and an internship program. The OpenMRS Implementers Network has formed collaborations with several other open source networks and is evolving regional OpenMRS Centres of Excellence to provide localized support for OpenMRS development and implementation. These initiatives are increasing the range of functionality and sustainability of open source software in the health domain, resulting in improved adoption and enterprise-readiness. CONCLUSIONS: Social organization and capacity development activities are important in growing a successful community-driven open source software model.

Ganglioneuromatous polyposis: a premalignant condition. Report of a case and review of the literature.

A 40-year-old man with ganglioneuromatous polyposis and an aggressive coexisting colorectal cancer is described. Contrary to previous reports, we believe that ganglioneuromatous polyposis should be considered a premalignant condition.

Development of an HIV clinical and research database for South Africa.

Health service restructuring in South Africa provides an opportunity to introduce appropriate Health Information System (HIS) technology. This is particularly relevant given the emerging HIV epidemic and the need to capture, translate and disseminate new experiences in HIV/AIDS care, support and clinical research. In 1994, a number of clinicians and health-care providers working in South Africa had begun to establish basic computerized databases to assist in research on HIV, but no standardized nomenclature or framework for collaboration was created. This paper describes a clinical and research database that could be used as an example for a standardized system by clinicians working in South Africa. The authors, with assistance from the National AIDS Research Programme of the Medical Research Council, created a prototype relational database using Microsoft Access. To test the prototype, 1057 HIV-positive patients from the infectious Disease Clinic at Johannesburg General Hospital were entered.

PIP: The restructuring of health services in South Africa presents an opportunity to introduce appropriate Health Information System technology to assist in research on HIV and AIDS. In 1994, a group of clinicians and health care providers, with assistance from the National AIDS Research Program of the Medical Research Council, initiated collaboration to establish basic computerized databases. The group proposed that data entered into the database should be captured as close to the point of care as possible, with connectivity to laboratory computers and assurance of confidentiality. The prototype relational database was designed using Microsoft Access. It includes tables on demographics, medical history, primary and secondary HIV indicators, medications, performance indicators, radiology results, laboratory findings, and vital statistics. To test the prototype, data on 1057 HIV-positive patients from the Infectious Disease Clinic at Johannesburg General Hospital were entered into the system. Among the data generated were a listing of the top 10 opportunistic infections, the average absolute CD4 count within a given time of the diagnosis of such an infection, and patient referral sources. If further field testing is successful, translation into a full database system, integration of restricted vocabulary coding, and distribution onto a client-server network are planned.

Bartonella (Rochalimaea) species as a cause of apparent "culture-negative" endocarditis.

Bartonella quintana (formerly Rochalimaea quintana) is a recently recognized cause of apparent "culture-negative" endocarditis. We describe a 39-year-old, homeless man who developed aortic valve endocarditis caused by B. quintana. He had a history of alcoholism and was seronegative for the human immunodeficiency virus. We established that B. quintana was the cause of the endocarditis on the basis of the isolation of B. quintana from blood cultures, the compatibility of histochemical stains of cardiac valve tissue, the reactivity of the polymerase chain reaction specific for B. quintana on cardiac valve tissue, and the failure to isolate an alternative causative organism despite extensive efforts. This is the second report of endocarditis caused by B. quintana and the fourth report of endocarditis caused by a Bartonella species. On the basis of the findings of this report and those of other recent reports, further study is warranted to determine the overall role of Bartonella species in apparent culture-negative endocarditis.

Bartonella (Rochalimaea) quintana bacteremia in inner-city patients with chronic alcoholism.

BACKGROUND: Bartonella (Rochalimaea) quintana is a fastidious gram-negative bacterium known to cause trench fever, cutaneous bacillary angiomatosis, and endocarditis. Between January and June 1993 in Seattle, we isolated B. quintana from 34 blood cultures obtained from 10 patients not known to be infected with the human immunodeficiency virus (HIV). METHODS: After identifying the isolates as B. quintana by direct immunofluorescence and DNA-hybridization studies, we determined strain hybridization with studies of restriction-fragment-length polymorphisms (RFLPs) of the intergenic spacer (noncoding) region of ribosomal DNA amplified by the polymerase chain reaction (PCR). To characterize the epidemiologic and clinical features of bartonella infections in these patients, we performed a retrospective case-control study using as controls 20 patients with blood cultures obtained at approximately the same time as those obtained from the index patients. RESULTS: B. quintana isolates from the 10 patients were indistinguishable by PCR-RFLP typing. All 10 patients had chronic alcoholism, and 8 were homeless (P = 0.001 for both comparisons with controls). The six patients who underwent HIV testing were seronegative. At the time of their initial presentation, seven patients had temperatures of at least 38.5 degrees C. Six patients had three or more blood cultures that were positive for B. quintana, and in four of these patients B. quintana was isolated from blood cultures obtained 10 or more days apart. Subacute endocarditis developed in two patients and required surgical removal of the infected aortic valve in one of them. Nine patients recovered; one died of sepsis from Streptococcus pneumoniae infection. CONCLUSIONS: B. quintana is a cause of fever, bacteremia, and endocarditis in HIV-seronegative, homeless, inner-city patients with chronic alcoholism.

Bone mineral changes in primary hyperparathyroidism.

We studied 34 patients with primary hyperparathyroidism in order to assess their bone mineral status, to determine its relationship to biochemical parameters (serum calcium and parathyroid hormone) and surgical status, and to determine the relationship between peripheral cortical bone and spinal trabecular bone in this disease. These patients were studied with radiogrammetry of the metacarpals, Norland-Cameron photon absorptiometry of the radius, quantitative computed tomography (QCT) of the spine, industrial radiography of the hands, and conventional radiography of the thoracolumbar spine. We also calculated a spinal fracture index from thoracolumbar spine films. We found that the appendicular measurements correlated well together, but less well with spinal QCT. The spinal fracture index correlated best with QCT (r = -0.55), although significant dispersion was noted. We found that, in general, these hyperparathyroid patients had statistically significant decrements in bone mineral content in both the appendicular and the axial portions of the skeleton. However, the decrement in the appendicular skeleton did not correlate well with that in the axial skeleton. Therefore we conclude that it is necessary to measure both peripheral and central bone mineral content in order to reliably assess the skeletal demineralizing effects of primary hyperparathyroidism in an individual patient.
