    Indigenous knowledge systems and traditional technologies have made and can continue to make a significant contribution to modern medicines with discovery of novel molecules in the treatment of various conditions. The traditional knowledge in our communities is passed on from generation to generation. Scientific evaluation of these compounds from traditional medicines can lead to discovery drugs with better efficacy and novel mechanism. The study aimed at determining the indigenous knowledge based preparations used for hypertension in Lusaka, Zambia. The specific objectives were: a). To determine the knowledge and practice of Traditional Health Practitioners in the management of HTN, b). To identify the parts of the plants utilized in the preparation of the IKS-based preparation used in the management of hypertension. c). To determine the procedure employed in preparing the IKS-based preparations used in the management of hypertension. d). To recommend for further elucidation of the possible active compounds in the indigenous based preparations and postulate possible pharmacological mechanisms of actions. The study adopted structured interviews complemented by non-participatory observations. Samples used by traditional healers were collected for identification and characterization A total of twelve (12) traditional healers registered with Traditional Health Practitioners of Zambia who manage hypertension were interviewed. The traditional healers interviewed had knowledge of causes of hypertension, only three (3) indicated bewitchment as one of the causes. spiritual method constituted an important method of diagnosis. The beliefs of Traditional Healers with regard to hypertension indicates their alignment to agreeing the scientific understanding of hypertension in terms of its causes, risk factors and complications. Traditional Healers in Zambia believe hypertension can be managed by some mode of action of the herbs. Common themes that emerged to determine the effectiveness of the herbs used included; patient feedback, physical appearance, confirmation at local clinic and increased urine output. Majority (5/12) felt that there herbs take atleast 7-14 before the effects are seen. All the traditional healers indicated using atleast two (2) types of herbal preparations to manage hypertension. Of the preparations mentioned three (3) were not of plant origin. These include; crocodile fat, pebble and honey. This study observed that the traditional healers of Zambia knowledge of causes and complications of hypertension are alligned to the scientific knowledge. Divination is however still the most important (50%) method used for diagnosis and witchcraft/ spiritual method forms an important method for some for diagnosis of hypertension. It is noteworthy that traditional healers in Zambia believe hypertension can be managed by some mode of action of the herbs a belief shared by the conventional management.

    A Preliminary Study of Knowledge, Attitude and Practice of Adverse Drug Reaction Reporting in a Teaching Hospital in Lusaka, Zambia
    (Zambian Medical Association, 2014-12) Prashar, Lavina; Musoke, Pamela
    Objectives of the Study: The study was aimed at examining ADR reporting practices and barriers among medical doctors, pharmacists, nurses, clinical officers, and medical residents at the University Teaching Hospital, Lusaka, Zambia. The specific objectives were: a) to assess the knowledge of ADR reporting among health professionals, b) to assess attitudes of health professionals towards ADR reporting, and c) to assess the practice of ADR reporting among health professionals. Materials and Methods: The study adopted a questionnaire-based cross-sectional method. One hundred and forty questionnaires were administered to health professionals working at the University Teaching Hospital, Lusaka. Statistical Analysis Used: The Statistical Package for the Social Sciences (SPSS) version 20 was used to run various descriptive statistics and to draw charts. Pearson's Chi-square test was used to observe the association of knowledge and attitude with experience and position, at significance level of 0.05. Results: One hundred and twenty-eight questionnaires were successfully filled in and returned, giving a response rate of 91.4%. Knowledge of ADR reporting among the professionals was extremely very low. Only one respondent obtained 50% of the total scores, i.e. 19 marks out of 34 marks; and no respondent got above 50%. The minimum score obtained was 0, the maximum score was 19, and the average score was 12.6 with a standard deviation of 3.555. There was no association between knowledge level of ADR reporting and age of the respondent (r=0.003 (n=123); p=0.973). Furthermore, there was no association between knowledge levels of ADR reporting and length of respondents' practice at UTH (r=0.013 [n=120]; p=0.886). Low knowledge levels of ADR reporting were attributed to lack of training. Only 17.7% of respondents had been trained in ADR reporting. The major factors that encouraged ADR reporting included: if the reaction was serious (84.7%); if the reaction was unusual (77.4%); if the reaction was to a new product (73.4%); if the reaction was well recognized for a particular drug (60.5%); and confidence in diagnosis of an ADR (46.0%). Factors that discouraged ADR reporting included: lack of feedback (73.5%); the level of clinical knowledge to decide whether an ADR had occurred (49.0%); lack of time to actively look for ADRs (46.9%); the information reported may be wrong (37.8%); lack of time to fill in a report (36.7%); and lack of need to report a recognized ADR because it will make little difference to knowledge (30.6%). Very few (12.7%) respondents had reported an ADR case. The major factors found to be responsible for under reporting of ADR include ignorant of reporting procedures (52.0%), lack of reporting forms (31.8%), and lack of appreciation of the importance of ADR reporting. Conclusion: This study observed that knowledge of ADR reporting was very low among health professionals at UTH. These deficiencies in knowledge and attitudes require urgent attention not only to improve the rate of ADR reporting, but also in order to improve the safety of the patients. Furthermore, the hospital management should improve awareness and training on ADR reporting
