Diagnosis and counselling of patients with acute HIV infection in South Africa.

OBJECTIVES: To identify, diagnose and counsel patients with acute HIV infection (AHI) during routine HIV testing in South Africa. METHODS: Patients with sexually transmitted infection and clients undergoing voluntary counselling and testing who were negative on rapid HIV antibody tests at a public youth clinic were recruited to the study and tested using HIV-1 PCR and third-generation ELISA. Results were made available at 1 week. Text message reminders and phone calls were employed to encourage patients to return for results. Patients with AHI were additionally visited at home. RESULTS: 902 participants were enrolled over the course of 1 year, reporting high levels of sexual risk behaviour, including 66.7% who did not use a condom at last sex. Six (0.67%) were diagnosed with AHI. Results and counselling were delivered to 62.3% of participants and all six patients with AHI. CONCLUSIONS: It is possible to perform routine diagnosis and counselling for acute HIV infection in a limited-resource setting. Provider outreach to patients may help in delivering results to a high proportion of patients, but will probably add to the already substantial cost of testing.

Creating a Framework to Integrate Residency Program and Medical Center Approaches to Quality Improvement and Patient Safety Training.

Quality improvement and patient safety (QIPS) are core components of graduate medical education (GME). Training programs and affiliated medical centers must partner to create an environment in which trainees can learn while meaningfully contributing to QIPS efforts, to further the shared goal of improving patient care. Numerous challenges have been identified in the literature, including lack of resources, lack of faculty expertise, and siloed QIPS programs. In this article, the authors describe a framework for integrated QIPS training for residents in the University of Washington Internal Medicine Residency Program, beginning in 2014 with the creation of a dedicated QIPS chief resident position and assistant program director for health systems position, the building of a formal curriculum, and integration with medical center QIPS efforts. The postgraduate year (PGY) 1 curriculum focused on the culture of patient safety and entering traditional patient safety event (PSE) reports. The PGY-2 curriculum highlighted QIPS methodology and how to conduct mentored PSE reviews of cases that were of educational value to trainees and a clinical priority to the medical center. Additional PGY-2/PGY-3 training focused on the active report, presentation, and evaluation of cases during morbidity and mortality conferences while on clinical services, as well as how to lead longitudinal QIPS work. Select residents led mentored QI projects as part of an additional elective. The hallmark feature of this framework was the depth of integration with medical center priorities, which maximized educational and operational value. Evaluation of the program demonstrated improved attitudes, knowledge, and behavior changes in trainees, and significant contributions to medical center QIPS work. This specialty-agnostic framework allowed for training program and medical center integration, as well as horizontal integration across GME specialties, and can be a model for other institutions.

The failure of routine rapid HIV testing: a case study of improving low sensitivity in the field.

BACKGROUND: The rapid HIV antibody test is the diagnostic tool of choice in low and middle-income countries. Previous evidence suggests that rapid HIV diagnostic tests may underperform in the field, failing to detect a substantial number of infections. A research study inadvertently discovered that a clinic rapid HIV testing process was failing to detect cases of established (high antibody titer) infection, exhibiting an estimated 68.7% sensitivity (95% CI [41.3%-89.0%]) over the course of the first three weeks of observation. The setting is a public service clinic that provides STI diagnosis and treatment in an impoverished, peri-urban community outside of Cape Town, South Africa. METHODS: The researchers and local health administrators collaborated to investigate the cause of the poor test performance and make necessary corrections. The clinic changed the brand of rapid test being used and later introduced quality improvement measures. Observations were made of the clinic staff as they administered rapid HIV tests to real patients. Estimated testing sensitivity was calculated as the number of rapid HIV test positive individuals detected by the clinic divided by this number plus the number of PCR positive, highly reactive 3rd generation ELISA patients identified among those who were rapid test negative at the clinic. RESULTS: In the period of five months after the clinic made the switch of rapid HIV tests, estimated sensitivity improved to 93.5% (95% CI [86.5%-97.6%]), during which time observations of counselors administering tests at the clinic found poor adherence to the recommended testing protocol. Quality improvement measures were implemented and estimated sensitivity rose to 95.1% (95% CI [83.5%-99.4%]) during the final two months of full observation. CONCLUSIONS: Poor testing procedure in the field can lead to exceedingly low levels of rapid HIV test sensitivity, making it imperative that stringent quality control measures are implemented where they do not already exist. Certain brands of rapid-testing kits may perform better than others when faced with sub-optimal use.

Patient experiences following acute HIV infection diagnosis and counseling in South Africa.

Individuals in the acute stage of HIV infection (AHI) have an elevated potential to transmit HIV and play a critical role in the growth of the epidemic. Routine identification and counseling of individuals during AHI could decrease transmission behavior during this key period. However, diagnosis of AHI may present challenges distinct from those experienced through diagnosis of established HIV infection. A study was conducted in a public youth clinic outside of Cape Town, South Africa, to identify and counsel individuals with acute stage HIV infection. In-depth interviews were conducted with patients following diagnosis. After counseling, patients were accepting of the testing regimen used to diagnose AHI. They used the knowledge of having been recently infected to identify the source of their infection, but did not retain or place importance on information regarding the increased ability to transmit HIV during the acute stage. Future interventions directed at the reduction of HIV transmission following diagnosis with AHI will need to find ways of making this information more salient, possibly through more culturally meaningful educational approaches.
