In the first year of the COVID-19 pandemic, health systems implemented programmes to manage outpatients with COVID-19. The goal was to expedite patients’ referral to acute care and prevent overcrowding of medical centres. We sought to evaluate the impact of such a programme, the COVID-19 Home Care Team (CHCT) programme.

Retrospective cohort.

Kaiser Permanente Northern California.

Adult members before COVID-19 vaccine availability (1 February 2020–31 January 2021) with positive SARS-CoV-2 tests.

Virtual programme to track and treat patients with ‘CHCT programme’.

The outcomes were (1) COVID-19-related emergency department visit, (2) COVID-19-related hospitalisation and (3) inpatient mortality or 30-day hospice referral.

We estimated the average effect comparing patients who were and were not treated by CHCT. We estimated propensity scores using an ensemble super learner (random forest, XGBoost, generalised additive model and multivariate adaptive regression splines) and augmented inverse probability weighting.

There were 98 585 patients with COVID-19. The majority were followed by CHCT (n=80 067, 81.2%). Patients followed by CHCT were older (mean age 43.9 vs 41.6 years, p

Despite CHCT following older patients with higher comorbidity burden, there appeared to be a protective effect. Patients followed by CHCT were more likely to present to acute care and less likely to die inpatient.

We aim to explore spatial variations in socioeconomic inequalities in HIV testing uptake in sub-Saharan Africa (SSA) at different geographical scales to identify potential geographical hotspots of inequalities. Additionally, to evaluate the potential benefits of HIV testing programmes, we assess whether local levels of HIV testing match the local levels of HIV prevalence.

A multi-country analysis of population-based cross-sectional surveys in SSA.

We analysed data from 25 SSA countries with Demographic and Health Surveys between 2011 and 2019.

Country-level analysis included 473 775 participants (312 104 women and 161 671 men) and cluster-level analysis included 328 283 individuals (241 084 women and 87 199 men). Women aged 15–49 years and men aged 15–54/59 years in selected households who were tested for HIV in the last 12 months were eligible. We quantified inequalities in self-reported recent HIV testing with the Slope Index of Inequality (SII) and the Relative Index of Inequality (RII) across geographical scales to capture sex-specific within-country spatial variations. We also conducted local Getis-Ord Gi* statistics to consider the autocorrelation in fine-scale SII and RII across countries. To assess the efficiency of HIV testing programmes, we measured the correlation between recent HIV testing and HIV prevalence through Spearman correlation across geographical scales.

We observed varying inequalities in recent HIV testing in magnitude and spatial distribution on both absolute and relative scales in many countries for both sexes at national and subnational levels. Hotspots of absolute and relative inequalities were mostly observed in Western and Central Africa with a few regions in Eastern and Southern Africa. Despite significant sex-specific correlations between testing and prevalence in all countries when assessed at the national level, we report an absence of such a correlation at fine scale in 17 of 50 sex-country combinations.

We highlight the importance of investigating the spatial variability of various HIV indicators and related inequalities across different geographical levels. Results may help inform an equitable distribution of HIV testing services.

Cerebral palsy (CP) is one of the leading causes of childhood disability globally with a high burden in low-income and middle-income countries (LMICs). Preliminary findings from the global LMIC CP Register (GLM CPR) suggest that the majority of CP in LMICs are due to potentially preventable causes. Such data are lacking in the Latin American region. Generating comparable epidemiological data on CP from this region could enable translational research and services towards early diagnosis and early intervention. We aim to establish a Latin American multicountry network and online data repository of CP called Latin American Cerebral Palsy Register (LATAM-CPR).

The LATAM-CPR will be modelled after the GLM CPR and will support new and emerging Latin American CP registers following a harmonised protocol adapted from the GLM CPR and piloted in Argentina (ie, Argentine Register of Cerebral Palsy). Both population-based and institution-based surveillance mechanisms will be adopted for registration of children with CP aged less than 18 years to the participating CP registers. The data collection form of the LATAM-CPR will include risk factors, clinical profile, rehabilitation, socioeconomical status of children with CP. Descriptive data on the epidemiology of CP from each participating country will be reported, country-specific and regional data will be compared.

Individual CP registers have applied ethics approval from respective national human research ethics committees (HREC) and/or institutional review boards prior to the establishment and inclusion into the LATAM-CPR. Ethical approval for LATAM-CPR has already been obtained from the HREC in the two countries that started (Argentina and Mexico). Findings will be disseminated and will be made publicly available through peer-reviewed publications, conference presentations and social media communications.
