Strengthening and utilizing response groups for emergencies flagship: a narrative review of the roll out process and lessons from the first year of implementation.

The World Health Organization Regional Office for Africa (WHO/AFRO) faces members who encounter annual disease epidemics and natural disasters that necessitate immediate deployment and a trained health workforce to respond. The gaps in this regard, further exposed by the COVID-19 pandemic, led to conceptualizing the Strengthening and Utilizing Response Group for Emergencies (SURGE) flagship in 2021. This study aimed to present the experience of the WHO/AFRO in the stepwise roll-out process and the outcome, as well as to elucidate the lessons learned across the pilot countries throughout the first year of implementation. The details of the roll-out process and outcome were obtained through information and data extraction from planning and operational documents, while further anonymized feedback on various thematic areas was received from stakeholders through key informant interviews with 60 core actors using open-ended questionnaires. In total, 15 out of the 47 countries in WHO/AFRO are currently implementing the initiative, with a total of 1,278 trained and validated African Volunteers Health Corps-Strengthening and Utilizing Response Groups for Emergencies (AVoHC-SURGE) members in the first year. The Democratic Republic of Congo (DRC) has the highest number (214) of trained AVoHC-SURGE members. The high level of advocacy, the multi-sectoral-disciplinary approach in the selection process, the adoption of the one-health approach, and the uniqueness of the training methodology are among the best practices applauded by the respondents. At the same time, financial constraints were the most reported challenge, with ongoing strategies to resolve them as required. Six countries, namely Botswana, Mauritania, Niger, Rwanda, Tanzania, and Togo, have started benefiting from their trained AVoHC-SURGE members locally, while responders from Botswana and Rwanda were deployed internationally to curtail the recent outbreaks of cholera in Malawi and Kenya.

Factors associated with loss to clinic among HIV patients not yet known to be eligible for antiretroviral therapy (ART) in Mozambique.

INTRODUCTION: Retention in HIV care prior to ART initiation is generally felt to be suboptimal, but has not been well-characterized. METHODS: We examined data on 37,352 adult pre-ART patients (ART ineligible or unknown eligibility) who enrolled in care during 2005-2008 with >1 clinical visit at 23 clinics in Mozambique. We defined loss to clinic (LTC) as >12 months since the last visit among those not known to have died/transferred. Cox proportional-hazards models were used to examine factors associated with LTC, accounting for clustering within sites. RESULTS: Of 37,352 pre-ART patients, 61% had a CD4 count within three months of enrolment (median CD4: 452, IQR: 345-611). 17,598 (47.1%) were ART ineligible and 19,754 (52.9%) were of unknown eligibility status at enrolment because of missing information on CD4 count and/or WHO stage. Kaplan-Meier estimates for LTC at 12 months were 41% (95% CI: 40.2-41.8) and 48% (95% CI: 47.2-48.8), respectively. Factors associated with LTC among ART ineligible patients included male sex (AHR(men_vs_non-pregnant women): 1.5; 95% CI: 1.4-1.6) and being pregnant at enrolment (AHR(pregnant_vs_non-pregnant women): 1.3; 95% CI: 1.1-1.5). Older age, more education, higher weight and more advanced WHO stage at enrolment were independently associated with lower risks of LTC. Similar findings were observed among patients whose ART eligibility status was unknown at enrolment. CONCLUSIONS: Substantial LTC occurred prior to ART initiation among patients not yet known to be eligible for ART, including nearly half of patients without documented ART eligibility assessment. Interventions are needed to target pre-ART patients who may be at higher risk for LTC, including pregnant women and patients with less advanced HIV disease.

Factors associated with late antiretroviral therapy initiation among adults in Mozambique.

BACKGROUND: Despite recent changes to expand the ART eligibility criteria in sub-Saharan Africa, many patients still initiate ART in the advanced stages of HIV infection, which contributes to increased early mortality rates, poor patient outcomes, and onward transmission. METHODS: To evaluate individual and clinic-level factors associated with late ART initiation in Mozambique, we conducted a retrospective sex-specific analysis of data from 36,411 adult patients who started ART between January 2005 and June 2009 at 25 HIV clinics in Mozambique. Late ART initiation was defined as CD4 count<100 cells/µL or WHO stage IV. Mixed effects models were used to identify patient- and clinic-level factors associated with late ART initiation. RESULTS: The proportion of patients initiating ART late decreased from 46% to 37% during 2005-2007, but remained constant (between 37-33%) from 2007-2009. Of those who initiated ART late (median CD4 = 57 cells/µL), 5% were known to have died and 54% were lost to clinic within 6 months of ART initiation (compared with 2% and 47% among other patients starting ART [median CD4 = 192 cells/µL]). In multivariate analysis, female sex and pregnancy at ART initiation (AOR(female_not_pregnant_vs._male) = 0.66, 95%CI [0.62-0.69]; AOR(pregnant_vs._non_pregnant) = 0.60, 95%CI [0.49-0.73]), younger and older age (AOR(15-25_vs.26-30) = 0.86, 95%CI [0.79-0.94], AOR(>45_vs.26-30) = 0.72, 95%CI [0.67-0.77]), entry into care via PMTCT (AOR(entry_through_PMTCT_vs.VCT) = 0.42, 95%CI [0.35-0.50]), marital status (AOR(married/in union_vs.single) = 0.87, 95%CI [0.83-0.92]), education (AOR(secondary_or_higher_vs.primary) = 0.87, 95%CI [0.83-0.93]) and year of ART initiation were associated with a lower likelihood of late ART initiation. Clinic-level factors independently associated with a lower likelihood of late ART initiation included CD4 machine on-site (AOR(CD4_machine_onsite_vs.offsite) = 0.83, 95%CI [0.74-0.94]) and presence of PMTCT services onsite (AOR = 0.85, 95%CI [0.77-0.93]). CONCLUSION: The risk of starting ART late remained persistently high. Efforts are needed to ensure identification and enrollment of patients at earlier stages of HIV disease. Individual and clinic level factors identified may provide clues for upstream structural interventions.

Factors Associated with Late Antiretroviral Therapy Initiation among Adults in Mozambique

Despite recent changes to expand the ART eligibility criteria in sub-Saharan Africa, many patients still initiate ART in the advanced stages of HIV infection, which contributes to increased early mortality rates, poor patient outcomes, and onward transmission. To evaluate individual and clinic-level factors associated with late ART initiation in Mozambique, we conducted a retrospective sex-specific analysis of data from 36,411 adult patients who started ART between January 2005 and June 2009 at 25 HIV clinics in Mozambique. Late ART initiation was defined as CD4 count<100 cells/µL or WHO stage IV. Mixed effects models were used to identify patient- and clinic-level factors associated with late ART initiation. The proportion of patients initiating ART late decreased from 46% to 37% during 2005­2007, but remained constant (between 37­33%) from 2007­2009. Of those who initiated ART late (median CD4 = 57 cells/µL), 5% were known to have died and 54% were lost to clinic within 6 months of ART initiation (compared with 2% and 47% among other patients starting ART [median CD4 = 192 cells/µL]). In multivariate analysis, female sex and pregnancy at ART initiation (AORfemale_not_pregnant_vs._male = 0.66, 95%CI [0.62­0.69]; AORpregnant_vs._non_pregnant = 0.60, 95%CI [0.49­0.73]), younger and older age (AOR15­25_vs.26­30 = 0.86, 95%CI [0.79­0.94], AOR>45_vs.26­30 = 0.72, 95%CI [0.67­0.77]), entry into care via PMTCT (AORentry_through_PMTCT_vs.VCT = 0.42, 95%CI [0.35­0.50]), marital status (AORmarried/in union_vs.single = 0.87, 95%CI [0.83­0.92]), education (AORsecondary_or_higher_vs.primary = 0.87, 95%CI [0.83­0.93]) and year of ART initiation were associated with a lower likelihood of late ART initiation.

Patients enrolled in HIV care in Mozambique: baseline characteristics and follow-up outcomes.

OBJECTIVE: To utilize routinely collected service delivery data from HIV care and treatment clinics in Mozambique to describe the patient population and programmatic outcomes from 2003 to 2009. METHODS: Data from patient charts were entered into an electronic database at 28 clinics in 5 Mozambican provinces. Patients' characteristics at enrollment in HIV care and at antiretroviral therapy (ART) initiation were examined. We calculated a corrected 12-month mortality estimate using a recently developed nomogram for sub-Saharan African ART patients. RESULTS: A total of 154,188 HIV-infected individuals (10,164 children <15 years old) were enrolled in HIV care services between 2003 and 2009. Of the 51,269 (36%) adults who started ART, 35% initiated ART with CD4 count <100 cells per microliter and 14.4% with World Health Organization stage IV. Just more than 10% (10.5%) of women were documented to be pregnant at enrollment. One-third of the 3,745 (37%) children who initiated ART were <2 years old, and 53% of those <5 years initiated ART severely immunosuppressed (CD4% <15%). Thirty-five percent of all children and 30% of those initiating ART met the definition of severe malnourishment (weight-for-age Z score <-3). Among those who initiated ART, the median estimated 12-month mortality rate across sites was 13.1% (interquartile range: 11.5%-16.0%) and 13.5% (interquartile range: 11.4%-17.4%) for adults and children, respectively. CONCLUSIONS: A substantial number of HIV-infected patients have been enrolled in HIV care and initiated on ART, with many patients having advanced HIV disease. With the release of new guidelines for ART use for adults, pregnant women, and children, extensive efforts are needed to ensure more timely initiation of ART.
