In 2008 and 2014, Ghana implemented DHS surveys that also collected data on the primary household-level malaria indicators. The 2019 GMIS used a nationally representative sample of 200 clusters and about 6,000 selected households. The survey was designed to provide information on key malaria control indicators such as the proportion of households with at least one mosquito bed net and at least one insecticide-treated net (ITN), the proportion of children under age 5 who slept under a net the previous night and the proportion who slept under an ITN, the proportion of pregnant women who slept under a bed net the previous night and the proportion who received intermittent preventive treatment (IPT) for malaria during their most recent pregnancy in the last 2 years, and the prevalence of anaemia and malaria parasitemia among children under age 5."},"version_statement":{"version_notes":"The data dictionary was generated from hierarchical data that was downloaded from the The DHS Program website (http:\/\/dhsprogram.com)."},"study_info":{"abstract":"The primary objective of the survey is to provide current estimates of key malaria indicators.

In 2019, Ghana created six new regions, resulting in a total of 16 regions and 260 administrative districts; however, during survey design, the new administrative boundaries were not available. The 2019 GMIS sampling frame is therefore based on the 10 regional boundaries defined according to the 2010 PHC. The frame is a complete list of all census enumeration areas (EAs) created for the PHC. An EA is the smallest geographic area that can be easily canvassed by an enumerator during an enumeration exercise. The sampling frame contains information about EA location, type of residence (urban or rural), the estimated number of residential households, and the estimated population.\n\nThe 2019 GMIS sample was stratified and selected from the sampling frame in two stages. In the first stage, 200 EAs (97 in urban areas and 103 in rural areas) were selected with probability proportional to EA size and with independent selection in each sampling stratum. In the second stage of selection, a fixed number of 30 households was selected from each cluster to make up a total sample size of 6,000 households.\n\nFor further details on sample design, see Appendix A of the final report.","coll_mode":"Computer Assisted Personal Interview [capi]","research_instrument":"Four types of questionnaires were used for the 2019 GMIS: the Household Questionnaire, the Woman\u2019s Questionnaire, the Biomarker Questionnaire, and the Fieldworker Questionnaire. The questionnaires were adapted to reflect issues relevant to Ghana. Modifications were determined after a series of meetings with various stakeholders from the NMCP and other government ministries and agencies, nongovernmental organisations, and international partners. The Household and Woman\u2019s Questionnaires in English and four local Ghanaian languages (Akan, Dagbani, Ewe, and Ga) were programmed into tablet computers, which enabled the use of computer-assisted personal interviewing for the survey. The Biomarker Questionnaire, also translated into four local languages, was filled out on hard copy and entered into the CAPI system when complete.","coll_situation":"Field data collection was conducted during an 8-week period from 25 September to 24 November 2019. Twelve teams were formed, with each including a supervisor, three interviewers, a health technician, and a driver. Each team was allocated specific clusters according to local language competency. The team spent an average of 3 days working in a cluster. Information on selected clusters and sampled households was directly uploaded into supervisors\u2019 tablets. When eligible respondents were absent from their homes, two or more call backs were made to offer respondents the opportunity to participate in the survey.\n\nIn addition to the field supervisors, there were national and regional monitors who supervised field activities and ensured the collection and transfer of blood slides to the laboratory. GSS, NMCP, and NPHRL field monitoring staff were responsible for data collection quality control and timely collection and transfer of slides from the field teams to the NPHRL. Periodically during fieldwork, a set of field check tables was run from the computerised data at GSS. Problems that appeared from reviews of these tables were discussed with the appropriate teams (during supervisory visits or briefing sessions), and attempts were made to ensure that they did not persist. In addition, GSS data processing staff provided teams with CAPI-related troubleshooting support during data collection.","weight":"Due to the non-proportional allocation of the sample to different divisions and their urban and rural areas and the possible differences in response rates, sampling weights is required for any analysis using the 2019 GMIS data to ensure the actual representativeness of the survey results at the national level as well as the domain levels.\n\nThe design weights were adjusted for household non-response and individual non-response to obtain the sampling weights for households and for women, respectively. Non-response was adjusted at the sampling stratum level. For the household sampling weight, the household design weight was multiplied by the inverse of the household response rate by stratum. For women\u2019s individual sampling weight, the household sampling weight was multiplied by the inverse of women\u2019s individual response rate by stratum. After adjusting for non-response, the sampling weights were normalized to obtain the final standard weights that appear in the data files. The normalization process was done to obtain a total number of unweighted cases equal to the total number of weighted cases at the national level for the total number of households and women. Normalization was done by multiplying the sampling weight by the estimated sampling fraction obtained from the survey for the household weight and the individual women\u2019s weights. The normalized weights are relative weights that are valid for estimating means, proportions, ratios, and rates but are not valid for estimating population totals or for pooled data.\n\nFor further details on sampling weights, see Appendix A.4 of the final report.","cleaning_operations":"Data for the 2019 GMIS were collected through questionnaires programmed into the CAPI application. The CAPI application was programmed by The DHS Program and loaded into the computers along with the Household, Biomarker, and Woman\u2019s Questionnaires. Using the Internet File Streaming System (IFSS) developed by The DHS Program, the field supervisors transferred data on a daily basis to a central location for data processing in the GSS office located in Accra. To facilitate communication and monitoring, each fieldworker was assigned a unique identification number.\n\nThe Census and Survey Processing (CSPro) program was used for data editing, cleaning, weighting, and tabulation. Data received from the field teams\u2019 CAPI applications were registered and checked for any inconsistencies and outliers at the GSS Head Office. Data editing and cleaning included an extensive range of structural and internal consistency checks. All anomalies were communicated to field teams, which resolved data discrepancies. The corrected results were maintained in master CSPro data files and then used in producing tables for the final report."},"analysis_info":{"sampling_error_estimates":"The estimates from a sample survey are affected by two types of errors: non-sampling errors and sampling errors. Non-sampling errors are the results of mistakes made in implementing data collection and data processing, such as failure to locate and interview the correct household, misunderstanding of the questions on the part of either the interviewer or the respondent, and data entry errors. Although numerous efforts were made during the implementation of the 2019 Ghana Malaria Indicator Survey (GMIS) to minimize this type of error, non-sampling errors are impossible to avoid and difficult to evaluate statistically.\n\nSampling errors, on the other hand, can be evaluated statistically. The sample of respondents selected in the 2019 GMIS is only one of many samples that could have been selected from the same population, using the same design and expected size. Each of these samples would yield results that differ somewhat from the results of the actual sample selected. Sampling errors are a measure of the variability between all possible samples. Although the degree of variability is not known exactly, it can be estimated from the survey results.\n\nSampling error is usually measured in terms of the standard error for a particular statistic (mean, percentage, etc.), which is the square root of the variance. The standard error can be used to calculate confidence intervals within which the true value for the population can reasonably be assumed to fall. For example, for any given statistic calculated from a sample survey, the value of that statistic will fall within a range of plus or minus two times the standard error of that statistic in 95% of all possible samples of identical size and design.\n\nIf the sample of respondents had been selected as a simple random sample, it would have been possible to use straightforward formulas for calculating sampling errors. However, the 2019 GMIS sample is the result of a multi-stage stratified design, and, consequently, it was necessary to use more complex formulas. Sampling errors are computed in SAS, using programs developed by ICF. These programs use the Taylor linearization method of variance estimation for survey estimates that are means, proportions, or ratios.\n\nA more detailed description of estimates of sampling errors are presented in Appendix B of the survey report.","data_appraisal":"Data Quality Tables\n- Household age distribution\n- Age distribution of eligible and interviewed women\n- Completeness of reporting\n- Births by calendar years\n- Number of enumeration areas completed by month, according to region, Ghana MIS 2019\n- Percentage of children age 6-59 months classified as having malaria according to rapid diagnostic test (RDT), by month and region, Ghana MIS 2019\n- Number of children age 6-59 months measured for malaria via rapid diagnostic test (RDT), by month and region (unweighted), Ghana MIS 2019\n\nSee details of the data quality tables in Appendix C of the final report."}},"data_access":{"dataset_use":{"contact":[{"name":"The DHS Program","affiliation":"","email":"archive@dhsprogram.com","uri":"http:\/\/www.DHSprogram.com"}],"cit_req":"Use of the dataset must be acknowledged using a citation which would include:\n- the Identification of the Primary Investigator\n- the title of the survey (including country, acronym and year of implementation)\n- the survey reference number\n- the source and date of download","conditions":"Request Dataset Access\nThe following applies to DHS, MIS, AIS and SPA survey datasets (Surveys, GPS, and HIV). \nTo request dataset access, you must first be a registered user of the website.
