Knowledge, attitude and practices about leprosy among medical officers of Hyderabad urban district of Andhra Pradesh.

In India, MDT was implemented through vertical programme staff of the National Leprosy Eradication Programme till the year 2001, when it was integrated into general health services (GHS). Human resource development of GHS is a vital, preparatory action for successful integration of leprosy into GHS. District Technical Support Teams (DTST) have been formed with responsibility for building the capacity of medical and paramedical staff of urban health posts (UHPs). In this context, it is necessary to know the current levels of Knowledge, Attitude and Practices (KAP) about leprosy prevailing among health staff at a given point in time, so that required knowledge and skills can be imparted, if need be. The present study is an attempt in this direction for assessing the KAP status of health staff working in Hyderabad city. 402 staff members (352 females and 50 males) working in urban health posts, the Employees State Insurance Corporation and the Central Government Health Services dispensaries in Hyderabad urban district in Andhra Pradesh were included in the study carried out in 2004 in order to assess KAP, and some operational parameters. A questionnaire was used to elicit responses of 110 medical officers in urban Hyderabad and the data were analysed and discussed. Medical officers have shown consistent higher knowledge on leprosy, followed by nursing staff as compared to other paramedical workers Only 40% of the medical officers had the opportunity of seeing at least 1 case of leprosy in their practice. Medical Officers who received training in leprosy and possessed reference material on leprosy have shown higher knowledge and practice. More than half of the study subjects did not have specific training in leprosy. Two major operational problems expressed by the medical officers were managing big crowds in OPD and time lost in meetings. 96 (87.3%) of 110 medical officers felt integration of leprosy services into general health services can be effectively implemented. 78 (71%) expressed that a leprosy patient with severe reaction needed priority attention at the out-patient department indicating good understanding of reactions in leprosy and a positive attitude towards such patients. There is a need to organize training at regular intervals to cover new persons as well as reinforcing and updating the knowledge of those already trained.

Observations on reactions of leprosy in the field.

In order to assess the incidence of reaction in leprosy, it would be necessary to examine the data from a field control unit. In this study, it was found, at a fully monitored control unit, that Type I reaction occurred in 3.9% of borderline cases and Type II in 23.7% of LL and BL cases. Even so, the load of reaction is not high since reaction of Type I and Type II together are seen only in 3.7% of all types of cases. A majority of them are of mild or moderate degree and could be treated as out-patients. Of the borderline cases, the BB type showed maximum rate of reaction. The BL type can present with both Type I and Type II reactions with a total incidence of 12.8%. While the BT type constituted 74% of total cases, reaction of Type I occurred in 3.1% of cases. Reaction also occurred in 0.8% of RFT cases.

Clinical diagnosis of leprosy cases.

The principle of leprosy control is based on secondary prevention with early detection of all cases and treatment with multidrug therapy. Eradication of leprosy warrants detection of all cases. Hence diagnosis of leprosy is of paramount importance to eradicate the cases. History taking gives all important information about the patient. Presenting complaint and contacts in family give useful guidelines to clinicians to arrive at the diagnosis. The objective of clinical examination is to elicit cardinal signs of leprosy through a systemic examination. Sensory testing, examination of nerves and examination of hands, feet and eyes are helpful in establishing diagnosis. Laboratory examination is not essential. Slit-skin smear examination for acid-fast bacilli shows positive results in a few cases. Diagnosis is complete once the clinical signs are established through clinical examination.
