The aim of this study was to investigate whether clinicians in Malawi could use clinical judgement alone to administer blood transfusions in accordance with guidelines. Clinicians at a district hospital did not use the Lovibond Comparator haemoglobin results provided by their laboratory as they felt them to be unreliable, preferring instead to rely on their(More)
SETTING Ntcheu District, Central Region of Malawi. OBJECTIVES To assess 1) the feasibility of introducing simple internal quality control procedures for acid-fast bacilli (AFB) microscopy, and 2) the quality of the district sputum smear microscopy service. DESIGN A simple internal quality control system was piloted in which district laboratory staff(More)
SETTING Ntcheu District, rural Malawi. OBJECTIVES 1) To locate smear-positive pulmonary tuberculosis patients who were identified during the first 6 months of 2000 but did not start treatment ('lost cases'); 2) to describe these patients' pathways to diagnosis, health status and socio-demographic characteristics; and 3) to explore why these patients did(More)
BACKGROUND To quantify the likely impact of recent WHO policy recommendations regarding smear microscopy and the introduction of appropriate low-cost fluorescence microscopy on a) case detection and b) laboratory workload. METHODOLOGY/PRINCIPAL FINDINGS An audit of the laboratory register in an urban hospital, Lilongwe, Malawi, and the application of a(More)
AIMS To evaluate the characteristics of manual haemoglobin methods in use in Malawi and provide evidence for the Ministry of Health in Malawi to enable them to choose a suitable method for district hospitals. METHODS Criteria on accuracy, clinical usefulness, user friendliness, speed, training time, and economic costs were determined by local health(More)
Laboratory services are run down in many low-income countries, severely constraining their input to patient care and disease surveillance. There are few data about the quality and cost of individual components of the laboratory service in poorer countries, yet this information is essential if optimal use is to be made of scarce resources. Staff time, range(More)
The prevalence of antibodies to human immunodeficiency virus type 1 (HIV-1), hepatitis C virus (HCV), human T lymphotropic virus I (HTLV-I), and hepatitis B (HBV) surface antigen (HBsAg) was determined in blood donors from Ntcheu, Malawi. Each donation was also screened for HIV-1 RNA and HCV RNA. Among 159 blood donations, the prevalence of HIV-1 infection(More)
SETTING Ntcheu district hospital, Malawi. OBJECTIVE To assess a screening strategy for tuberculosis (TB) suspects using two sputum smears. DESIGN A strategy of screening all TB suspects with two sputum smears for 6 months (1 July-31 December 1998) was compared with the period 1 January to 30 June 1998 during which the strategy of screening TB suspects(More)
Laboratory conditions and procedures for sputum smear microscopy (acid-fast bacilli) were assessed in 38 hospitals throughout Malawi. Of these, 17 (45%) had an area of less than 25 m2, eight (21%) had a separate room for tuberculosis work, and five (13%) had a safety cabinet. All laboratory personnel wore gloves, but in several hospitals there was no white(More)
