The COVID-19 pandemic has caused a huge impact towards the teaching and learning activities in medical schools. Due to the outbreak, the curricular activities were shifted to a mainly digitised version of learning format. The purpose of this paper is to present the study design and methodology of a population-based survey on the impact of COVID-19 among medical students. The survey aims to investigate the level of knowledge, attitudes and practices (KAP) on the COVID-19 pandemic, the online learning readiness and psychological status among medical students in Universiti Sains Islam Malaysia (USIM). A universal sampling method will be used that involve 475 medical students from Year 1 to Year 6 in USIM. The data collection will be conducted through an online survey. The questionnaire consists of three components: the study of KAP on COVID-19, the online learning readiness and psychological impact of COVID-19 pandemic. Both of the KAP and online learning readiness questionnaire will be adopted, adapted and validated from previous research and will be based on a local study. As for the depression, anxiety and stress, the Depression, Anxiety and Stress Scale (DASS) questionnaire will be used. Duration of data collection is expected to be one month, and findings are expected to be ready by three months from the last data collection date. The exposure variables include sociodemographic factors and years of study, while the outcomes are the KAP scores, online learning readiness level, and DASS scores. Relationships between the outcomes and associated factors will be analysed once data collection is completed.

‘Klinik Pakar Mata Bergerak’ (KLiP Mobile), translated to specialised ophthalmology mobile clinic is a programme that provides ophthalmology care in the rural community of Negeri Sembilan. This study was conducted to determine the prevalence of cataracts and its associated factors among rural adults in Malaysia through an outreach programme of specialised ophthalmology services by KLiP Mobile. This is a cross-sectional study carried out from January 2016 until March 2018 and was conducted in rural areas of all seven districts in the state of Negeri Sembilanvisited by the KLiP Mobile. Universal sampling was applied to all adults attending the mobile clinic. The participants are those who were referred by the government community clinics and walk-in patients. The total number of participants in this study was 1480. The mean (SD) age for the study population was 56 (16.9), by which majority were Malay (n = 1220, 82.4%) and female (n = 809, 54.7%). Most of them received either primary (n = 604, 42.4%) or secondary education (n = 577, 40.5%). The majority of participants were categorized into the low-income group, with a monthly income of less than RM 3,000 (n = 1118, 92.4%). The prevalence of cataracts in the study population was 28.6%. In the multivariate analysis, factors significantly associated with cataracts were being male, having no formal education, race and suffering from hypertension. The prevalence of cataracts in rural areas is considerably high. This study highlights the need for baseline information for future study or as the main reference by the policymakers for policy development related to improving vision and eye care among the populations in Malaysia.
