Barriers to HIV-associated lymphoma diagnosis in Soweto, South Africa: A nurse's perspective.

Abstract

e18727 Background: Delayed diagnosis of aggressive lymphoma in people living with HIV (PLWH) in South Africa is an emerging public health crisis due in part to PLWH living longer on antiretroviral therapy. The main driver of this delay has been shown to occur during the healthcare-practitioner interval that represents the time from presentation to the healthcare center until a diagnosis is confirmed. We set out to explore the barriers contributing to the prolonged healthcare-practitioner interval during the diagnosis of aggressive B-cell lymphoma in PLWH. We provide a nurse perspective, often the first contact a patient will have within the public healthcare sector in Soweto, South Africa. Methods: We conducted a total of nine qualitative in-depth interviews (IDIs) between May-August 2022 with nurses at four public healthcare clinics in Soweto, South Africa. Eligible participants were purposively sampled provided that they had at least 5 years’ experience working with PLWH. All IDI’s were conducted by an experienced, multi-lingual qualitative researcher in a private room at the respective clinic. A semi-structured interview guide was developed to explore the following topics: provider experience in the healthcare system, experience with taking care of PLWH and experience in distinguishing lymphoma from tuberculosis (TB). The interviews lasted on average 67 minutes and were conducted in the participants preferred local language and/or English. IDIs were audio-recorded, transcribed verbatim, and entered into NVIVO for framework data analysis mapped onto a socio-ecological model exploring barriers at the institutional level. Results: Majority of participants were female (7/9; 78%) with a median age of 39 years. Two nurses held enrolled nurse qualifications (entry level) and 7 nurses held professional qualifications with a median of 10 years’ experience in healthcare. Participants report fundamental barriers that occur at the health system level including limited knowledge about lymphoma by providers; structural limitations at the clinic including staffing shortages and limited resources; poor referral/triage process for lymphoma; and lack of continuity in patient care. In contrast, a clear referral process for TB diagnosis and treatment was noted by the nurses. Nurses perceived that patient level barriers that result in advanced stage cancer presentations include use of alternative and traditional medicine. Conclusions: A clear distinction between referral and triage of suspected TB vs lymphoma diagnoses emerged. Nurses perceive that utilization of traditional medicine by patients results in advanced stage cancer diagnoses. Interviews with lymphoma patients are ongoing and interviews with providers at the TB clinics and with traditional healers in the region are planned to better understand the role that these barriers play in delayed lymphoma diagnosis in South Africa.
