Antenatal screening for HIV remains low in Nepal. Identifying factors associated with the uptake of antenatal screening is essential to increase uptake and prevent mother-to-child transmission (MTCT). This study investigated the effects of individual-level and district-level characteristics on the utilisation of antenatal screening for HIV in Nepal and how these effects changed between 2016 and 2022.

We used publicly available cross-sectional data from 2016 to 2022 Nepal Demographic and Health Surveys.

Stratified, multistage, random sampling was used to collect nationally representative data.

1978 and 2007 women aged 15–49 years who gave birth in the 2 years preceding the surveys.

We used multilevel models to estimate associations between antenatal screening and potential factors influencing it in 2016 and 2022. We used districts as a random effect and looked at the intraclass correlation coefficients to disentangle the geographical effects. To distinguish barriers to HIV screening from barriers to accessing antenatal care (ANC) services, we performed similar analyses with whether the woman attended at least one ANC visit as the dependent variable.

Factors associated with antenatal screening have not changed significantly between 2016 and 2022. Higher uptake of HIV screening was found among women with higher education, the pregnancy being desired later and women who had four or more ANC visits. Being from a poorer family and having low knowledge of MTCT and the medicines to prevent transmission were associated with lower uptake. From the supply side, no factors had a significant effect on antenatal screening. Factors associated with antenatal screening and those associated with any ANC were different. Our results also showed a partial importance of geographical factors on screening uptake.

Our results supported that antenatal screening could be improved by enhancing access to information and improving the availability of free screening.

Delirium is a syndrome characterised by a disturbance in attention, awareness and cognition as a result of another physical condition. It occurs in up to 50% of patients after cardiac surgery and is associated with increased mortality, prolonged intensive care and hospital stay and long-term cognitive dysfunction. Identifying effective preventive interventions is important. We will therefore conduct a systematic review to identify all randomised controlled studies that have tested a pharmacological or non-pharmacological intervention to prevent delirium.

We will search electronic databases (CDSR (Reviews), CENTRAL (Trials), MEDLINE Ovid, Embase Ovid, PsycINFO Ovid) as well as trial registers (clinicaltrials.gov and ISCRTN) for randomised controlled trials of both pharmacological and non-pharmacological interventions designed to prevent delirium after cardiac surgery in adults. Screening of search results and data extraction from included articles will be performed by two independent reviewers using Rayyan. The primary outcome will be the incidence of delirium. Secondary outcomes include: duration of postoperative delirium, all-cause mortality, length of postoperative hospital and intensive care stay, postoperative neurological complications other than delirium, health-related quality of life and intervention-specific adverse events. Studies will be assessed for risk of bias using the Cochrane RoB2 tool. A narrative synthesis of all included studies will be presented and meta-analysis (if appropriate network meta-analysis) will be undertaken where there are sufficient studies (three or more) for pooling results. Results will be reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement.

No ethical approval is required. This review will be disseminated via peer-reviewed manuscript and conferences.
