Doctors' Use of Laboratory Tests in the Diagnosis and Treatment of Patients

The provincial health budgets in South Africa are under enormous pressure and; annually; budgets are exceeded by most hospitals and clinics. Laboratory tests requested by clinicians are contributing to the problem of over-expenditure. The aim of this study was to determine from patients' files whether doctors were using laboratory tests prudently during their treatment of patients in the outpatient department (OPD) of the National District Hospital in Bloemfontein. A descriptive study was carried out using all the files of patients who visited the OPD in a three-month period (1 July to 30 September 2005) for whom laboratory tests were requested by the attending physician. The majority (31.3) of patients for whom laboratory tests were requested presented to the OPD with cardiovascular complaints or diagnoses; followed by endocrine (27.8) and musculoskeletal (16.3) complaints or diagnoses. Between one and three tests were requested for most patients; i.e. 33and 15; respectively. The most frequently requested tests were erythrocyte sedimentation rate (8.1); urea and electrolytes (7.7); urine microscopy; culture and sensitivity (6.4); cholesterol (6.1); full blood count (5.7) and thyroid profile (TSH 4.6; T4 2.6and thyroid functions 2.3). In 70.4of cases; results were documented and; in 59.1; the physician's management plans indicated the incorporation of laboratory test results into the patient's treatment regimen. Our findings indicated inappropriate documentation and application of test results. Interventions to improve physician behaviour include education; guidelines; feedback; leadership and redesign of requisition forms

Occupational Exposure to Bloodborne Viruses amongst Medical Practitioners in Bloemfontein; South Africa

Background : The possibility of occupational exposure to bloodborne viruses such as HIV; hepatitis B virus (HBV) and hepatitis C virus (HCV) is an everyday reality to health care workers. This study reports on doctors' extent and outcome of exposure to bloodborne viruses in Bloemfontein. Methods : descriptive study was done. Doctors (n=441) actively involved in public and/or private medical practice were requested to anonymously complete a questionnaire regarding occupational exposure to bloodborne viruses (HIV; HBV; and HCV). Results : A response rate of 51.7 was obtained. More than half (54.2; 95 CI [ 47.7 ; 60.5 ]) of respondents were exposed to bloodborne viruses; 48.3 occurring with HIV positive patients and 4.3with known HBV positive patients; and no positive HCV patients. After exposure occurred; 68.9 of patients were tested for HIV; 10.9 for HBV and only 4.2 for HCV infection. The frequency of serological testing for doctors immediately after exposure was 65.3 for HIV; 21.7 for HBV and 8.2 for HCV. No seroconversion to HIV or HCV was reported; while two seroconversions to HBV were reported. Most exposures occurred as a result of needle stick injury (85) and occurred in the operating theatre during . The majority (59.8procedures 59.3)of exposed doctors did not take any prophylactic treatment and those who did; did not always complete the treatmentConclusion : The risk of seroconversion to HIV after occupational exposure was as expected; while seroconversion to HBV was less than expected. The lack of adequate follow up serological testing after occupational exposure is alarming. It is the responsibility of the occupationally exposed doctor to adequately comply with prophylactic measures and undergo serological testing to ensure the least possible risk of contracting infection from a bloodborne virus

Good Short-Term Outcome of Kangaroo Mother care in Low Birth Weight Infants in a Rural South African Hospital

Objective: The aim of the study was to determine the outcome of kangaroo mother care (KMC) in low birth weight infants at a community hospital. Methods : This descriptive study included 87 mothers and their low birth weight infants who were in a stable condition and eligible for KMC at Dr JS Moroka Hospital; Thaba Nchu. The infants were assessed four times: at birth; twice during hospitalisation; and a week after discharge. Infants received breast milk exclusively.Results : Regarding the mothers' obstetric history (n=87); gravidity ranged from 1 to 7 (median 3); with a 43 incidence of miscarriage. The median birth weight of the infants (n=87) was 1.5 kg (first assessment); the discharge weight (third assessment) was 1.8 kg; and a week after discharge (fourth assessment) it was 2.2 kg. Initially the infants lost weight significantly from birth to the second assessment (95 CI for median decrease [-0.02; -0.01]); but significantly gained weight from the second to the third (95 CI for median decrease [0.27; 0.33]) and from the third to the fourth assessment (95 CI for median decrease [0.32; 0.45]). Approximately half (49) of the infants had developed jaundice by the time of second assessment. These babies had a significantly lower birth weight [0.12;0.30]. Conclusion : Our findings confirm that infants with a low birth weight treated with KMC can have a good growth pattern; and exclusive breast milk is sufficient to guarantee such growth. Kangaroo mother care is a safe method for stable infants with a low birth weight in a community hospital

Scientific Letter : Knowledge of Sexually Transmitted Diseases and HIV/AIDS Symptoms of Women Receiving Termination of Pregnancy; Bloemfontein

In 2002; we conducted a cross-sectional study to determine the profile of women seeking termination of pregnancy (TOP) in the Free State and to find out whether TOP was being used as a family planning method. The participants' contraceptive use and termination of pregnancy profile have been described elsewhere. This letter describes the knowledge of STD and HIV/AIDS symptoms of women seeking TOP

Profile of registrars and reasons for specialisation

Introduction The shortage of general practitioners is a worldwide phenomenon and occurs in countries such as Canada; the United States of America and Saudi Arabia. Increasingly fewer students are interested in general practice as an occupation. Choosing a speciality is a complex process and is dependent on a wide range of intrinsic and extrinsic factors; including preference at the start of studies; experience during undergraduate training; and environmental factors such as cultural and socio-economic background. The aim of this study was to determine the profile of registrars at theFaculty of Health Sciences (University of the Free State); as well as their reasons for specialisation. Method All departments were contacted and the first author circulated questionnaires and informed consent forms during the academic afternoons. Questionnaires and informed consent forms were available in Afrikaans and eng. Results Of the 150 questionnaires handed out; 109 were used for analysis (122 were received; of which 13 were incomplete). Most of the respondents were Afrikaans speaking (81.7
