LLIN monitoring data - Dominican Republic 2023|疟疾防控数据集|公共卫生监测数据集

Description of the studyThis data corresponds to a survey conducted in 2023 to monitor LLIN post distribution in the two main malaria foci of the Dominican Republic: Azua and San Juan. In Azua, the survey was conducted between 4 and 6 months post-distribution. In San Juan one year post-distribution.The survey was conducted in a random sample of households of each focus. The sample size per focus was calculated using the software Epi Info following simple random probability sampling, aiming to obtain a 95% confidence level and a ±6% error in the percentage of houses with enough nets to cover all sleeping spaces and considering that Azua and San Juan had a finite number of households. The number of houses visited in each locality was calculated based on the proportion of the households in each locality out of the total number of households in localities that received LLINs. In the absence of an updated population census, the total number of households in each locality was obtained from reports made during the LLIN installation and IRS campaigns. To define the households to be visited, the total number of households was divided by the number of households to be visited in the locality to obtain the interval for selecting households in the field (e.g. if the locality had 150 households and 15 had to be visited, field teams would interview 1 out of every 10 households they encountered). Fieldworkers started at a random corner of the locality and chose households based on the selection interval (e.g. 1 every 10 households).Each household received a survey in Spanish (Additional file 1). The survey included questions addressed to the head of the household, questions addressed to a random member of the household, and questions about a randomly selected LLIN in the household. Due to the absence of an updated census of the population, the random member was selected by the surveyor in situ, and so was the random LLIN (considering both installed and uninstalled nets present in the household). Several of the questions were verified by the surveyors inside the house by visual inspection of sleeping spaces, nets or net drying places. The physical integrity of the LLINs was verified in situ by extending the net and counting the holes of four different sizes as per WHO guidelinesDescription of the data collection tool and data storageThe data was collected in Survey CTO and stored in a cloud Survey CTO server v2.81.1.File structureThere are two csv files. One contains the raw data from the surveys conducted in Azua and San Juan. Each line in the data set represents one questionnaire in one household. All household identifiers (i.e. coordinates, address and name of the household owner) were removed to anonymize the data. The other one contains the data dictionary explaining the meaning of each variable in Spanish and English.
