A chart review study was conducted to determine the prevalence of syphilis and explore the associated risk factors among men who have sex with men (MSM) who attended a large HIV clinic in Trinidad during the period January–December 2019. Patients were routinely screened for syphilis annually, and demographic, clinical, and laboratory data were extracted from the medical records. Descriptive and bivariate analyses were performed, and factors significantly associated with a syphilis diagnosis were assessed using multivariate logistic regression. During the period, 218 MSM were seen, age range 19–67 years, and median age 34.0 years. The prevalence of syphilis was 41.3% (90/218), and 71.1% (64//90) of these infections were asymptomatic. Multivariate analysis using logistic regression showed that MSM living with HIV in the 30–34 years old-age group (OR, 4.32; 95% CI, 1.04–18.02), and those with a previous history of treated syphilis (OR, 10.18; 95% CI, 4.60–22.53) were more likely to be diagnosed with syphilis. The prevalence of syphilis is high among MSM attending the HIV clinic in Trinidad, and most of these infections were asymptomatic; hence, targeted and sustained interventions to reduce syphilis transmission are urgently required. Repeat episodes of syphilis may play a role in the transmission dynamics of syphilis in MSM.

Background Patients who default from HIV care are usually poorly adherent to antiretroviral treatment which results in suboptimal viral suppression. The study assessed the outcomes of retention in care and viral suppression by expansion of an intervention using two patient tracers to track patients lost to follow up at a large HIV clinic in Trinidad. Methods Two Social Workers were trained as patient tracers and hired for 15 months (April 2017–June 2018) to call patients who were lost to follow up for 30 days or more during the period July 2016–May 2018 at the HIV clinic Medical Research Foundation of Trinidad and Tobago. Results Over the 15-month period, of the of 2473 patients who missed their scheduled visits for 1 month or more, 261 (10.6%) patients were no longer in active care—89 patients dead, 65 migrated, 55 hospitalized, 33 transferred to another treatment clinic and 19 incarcerated. Of the remaining 2212 patients eligible for tracing, 1869 (84.5%) patients were returned to care, 1278 (68.6%) were virally unsuppressed (viral load > 200 copies/ml) and 1727 (92.4%) were re-initiated on ART. Twelve months after their return, 1341 (71.7%) of 1869 patients were retained in care and 1154 (86.1%) of these were virally suppressed. Multivariate analysis using logistic regression showed that persons were more likely to be virally suppressed if they were employed (OR, 1.39; 95% CI 1.07–1.80), if they had baseline CD4 counts < 200 cells/mm3 (OR, 1.71; 95% CI 1.26–2.32) and if they were retained in care at 12 months (OR, 2.48; 95% CI 1.90–3.24). Persons initiated on ART for 4–6 years (OR, 3.09; 95% CI 1.13–8.48,), 7–9 years (OR, 3.97; 95% CI 1.39–11.31), > 10 years (OR, 5.99; 95% CI 1.74–20.64 were more likely to be retained in care. Conclusions Patient Tracing is a feasible intervention to identify and resolve the status of patients who are loss to follow up and targeted interventions such as differentiated care models may be important to improve retention in care.

Background: Patients who default from HIV care are usually poorly adherent to antiretroviral treatment which results in suboptimal viral suppression. The study evaluated the effect and cost of expanding an intervention using two Patient Tracers to track and return to care patients lost to follow up at a large HIV Clinic in Trinidad.Methods: Two Social Workers were trained as Patient Tracers and hired initially for 6 months (April –September 2017), then extended to 15 months (April 2017 – June 2018) to call patients who were lost to follow up for 30 days or more during the period July 2016 – May 2018 at the HIV Clinic Medical Research Foundation of Trinidad and Tobago. Both the outcomes of the intervention, and costs were assessed over time. Results: Over the 15 month period, of the of 2,473 patients who missed their scheduled visits for one month or more, 261 (10.6%) patients were no longer in active care - 89 patients dead, 65 migrated, 55 hospitalized, 33 transferred to another treatment clinic and 19 incarcerated. Of the remaining 2,212 patients eligible for tracing, 1,794 (81.1%) patients were returned to care at an average cost of $38.09 USD per patient returned to care as compared to 589 of 866 (68%) patients returned to care over the 6 month period (p < 0.001) at an estimated cost of $47.72 USD per patient returned to care (p<0.001). Of the 1,794 patients returned to care, 1,686 (94%) were re-initiated/started on anti-retroviral therapy and 72.7% of these were virally suppressed (viral load <1,000 copies/ml) as of December 2018.Conclusions: Patient Tracing is a feasible and effective intervention to identify and resolve the status of patients who are loss to follow up to bring these patients back into care with the aim of achieving viral suppression on antiretroviral therapy. Over time the effect of costs of patients returned to care demonstrated greater yields making patient tracing a sustainable intervention for programmes to identify and return patients to care.
