Knowledge, attitudes and practices of oral health care workers in Lesotho regarding the management of patients with oral manifestations of HIV/AIDS

Abstract

Lesotho has the third highest prevalence of HIV in the world with an estimated 23% of the adult population infected. At least 70% of people living with HIV/AIDS (PLWHA) have presented with oral manifestation of HIV as the first sign of the disease. Oral health workers regularly encounter patients presenting with oral lesions associated with HIV disease and therefore need to have adequate knowledge of these conditions for diagnosis and management. The aim of the present study was to determine the knowledge, attitudes and practices of oral health care workers (OHCW) of Lesotho regarding the management of oral manifestations of HIV/AIDS. A descriptive cross-sectional survey was conducted on all 46 OHCW in 26 public and private care facilities in all ten districts of Lesotho. A self - administered questionnaire was used to gather information. The response rate was 100%. Nearly all (94.7%) agreed that oral lesions are common in people living with HIV and/or AIDS. The majority (91.3%) named oral candidiasis (OC) as the most common lesion found in PLWHA while Kaposi's Sarcoma (KS) (34.7%) and Oral Hairy Leukoplakia (OHL) (32.6%) were mentioned as the least common oral lesions of HIV. Most correctly identified the images of oral candidiasis (97.8%), angular cheilitis (86.9%) and herpes zoster (80.4%). Only 16.7% felt they had comprehensive knowledge of oral HIV lesions, although 84.8% reported having previously received training. Almost three quarters (71%) reported that there was no need to treat HIV positive patients differently from HIV negative patients. OHCW in Lesotho demonstrated high confidence levels in their competence in managing dental patients with oral lesions associated with HIV, however, they lacked an in-depth knowledge in this regard. Amongst this group there is a need for comprehensive training with regards to diagnosis and management of oral lesions of HIV including the training of other cadres of health care workers together with nurses and community health workers.
