An analysis of the pattern of detection of leprosy patients by institutions in the general health services in Sri Lanka after the integration of leprosy services into general health services.

Integration of leprosy services into the General Health Services was initiated in 2001 in Sri Lanka, and by the end of 2003 all services related to leprosy care were fully integrated. Against this background, routinely collected data available at the Anti-Leprosy Campaign for a 3-year period from 2000-2003 were analyzed to identify the pattern of the detection of cases by hierarchical institutions in the General Health Services. The analysis showed that more than 75% of leprosy patients had been detected at base, general and teaching hospitals and this trend was increasing proportionally during the period of concern (P < 0.001). Teaching hospitals had detected more than 50% of patients and this trend was also proportionally increasing. Nearly one-third of patients detected at teaching hospitals had been detected at the Central Leprosy Clinic (CLC) at the National Hospital. The trend for case detection at the CLC was decreasing proportionally and in absolute terms during the 3-year period after integration. More than 60% of leprosy patients had been detected at institutions where consultant dermatologists were available. The analysis concluded that centralized leprosy diagnostic and treatment services have been taken over by the institutions in the General Health Services but within districts these activities are predominantly concentrated on higher level institutions with consultant dermatological services. This suggests that similar to the existing general trend of by passing of lower level institutions by patients to seek treatment at higher-level institutions, which are perceived to provide a service of better quality, leprosy patients too prefer to seek treatment at these institutions.

Processes and challenges: how the Sri Lankan health system managed the integration of leprosy services.

At the end of 1999, the Ministry of Health in Sri Lanka took the bold decision to integrate its Leprosy Services within the country's general health system. The integration was completed in February 2001 and is already starting to bear fruit, but implementing the necessary changes has been a challenging task. Many new procedures had to be established, logistics improved, attitudes changed and health workers trained. A broad bridge between curative and preventative health services needed to be built. Integration efforts were supported by an advertising campaign to inform people that leprosy, like any other illness, can be treated at all health facilities. Contrary to the expectation that quality of service would drop following integration, more cases are now detected and an extensive network of government doctors is able to diagnose, treat and manage leprosy patients more efficiently. Prevalence has increased by 36% and the new case load by 41%. A few areas still need more attention, such as integrating MDT supplies within existing systems and improving the flow of information, but nonetheless the ownership of leprosy is shifting rapidly to local health services.

Social marketing to eliminate leprosy in Sri Lanka.

PIP: Leprosy is a chronic infectious disease which, if untreated, can lead to permanent and progressive nerve damage and thus to deformities of the limbs, eyes, and face. People with leprosy have long been ostracized by society. The clinical signs of leprosy include insensitive skin lesions and thickened peripheral nerves. Untreated infectious leprosy cases are the main source of infection, transmitting the disease through nasal secretions. People with low cell-mediated immunity are at risk of developing clinically active leprosy irrespective of gender, age, or social class. The World Health Organization (WHO) has, since 1982, recommended multiple drug therapy (MDT) against leprosy, an approach capable of curing the disease within 1 year and interrupting its transmission. According to WHO, leprosy is currently a public health problem in 55 countries and more than 20% of the estimated 1.15 million cases of leprosy worldwide remain undetected. Although Sri Lanka was the first country in South Asia to provide MDT to all registered leprosy patients, first making it available in 1984, the disease continues to be transmitted due to the large number of undetected cases in the country. An ongoing social marketing program was therefore launched in 1990 by the local health ministry and the Novartis Foundation for Sustainable Development to eliminate leprosy from Sri Lanka. The program encourages people with suspicious skin lesions to seek diagnosis and care, teaches health care providers to recognize leprosy and refer cases for treatment, and helps the general public to understand that leprosy is just a normal disease. The socially marketed product is MDT, provided free-of-charge by the Novartis Foundation to all leprosy patients.^ieng
