Secondary Data Analysis (Pros and Cons)

The databases serve the primary function of managing and implementing insurance coverage, processing, and payment. Medical chart abstraction—Medical charts primarily contain information collected as a part of routine medical care. The originators of the primary research are largely self-governed and controlled by the marketer. The ease with which this is accomplished depends on whether the information is in a relational database or exists as scanned documents. Likewise, birth certificates are available through State departments and may be useful in registries of children or births.

strengths of secondary data

In accessing data from one registry for the purposes of another, it is important to recognize that data may have changed during the course of the source registry, and this may or may not have been well documented by the providers of the data. Finally, in addition to reliability and suitability of the data, it should be declared adequate and accurate as far as practicable. A pilot collection is recommended for this labor-intensive method of data collection to explore the availability and reproducibility of the data of interest. Direct Personal Interview The researcher contacts the respondents personally and obtains all the relevant information for his study. Confidentiality can be enhanced by assigning a registry-specific identifier via a crosswalk algorithm, as discussed below.

May Show Difficulties in Conducting Primary Research In many cases, the originators of secondary research include details of how the information was collected. Data elements can be grouped into categories identifying the specific variable or construct they are intended to describe. For example, data collection for many federal data sets is often performed by staff members who specialize in certain tasks and have many years of experience in that particular area and with that particular survey. This information is called administrative data. Secondary data analysis involves a researcher using the information that someone else has gathered for his or her own purposes. Secondary Data Primary data is original data that researchers collect for a specific purpose.

The main cost in undertaking secondary analysis is that of obtaining the data. The findings revealed that although there was a number of Key Performance Indicators used to measure performance, not all of them had strong correlation with O level results. Information collected includes demographic, gender, age, education, economic, housing, and work data. It is a source of empirical data on attitudes covering a majority of the world´s population nearly 90% It is carried out by a worldwide network of social scientist who, since 1981, have conducted representative national surveys in almost 100 countries. A term may have different meaning for different people, example a term 'youth' used is ambiguous and one needs to find what is the assumed age taken by primary researcher.

Another advantage is that it might be considered to be more trustworthy, in that they have greater validity than secondary data. Researchers leverage secondary data analysis in an attempt to answer a new research question, or to examine an alternative perspective on the original question of a previous study. If they're collected objectively, with careful planning and sampling, controls in place and other features of methodology adhered to, then they're likely to be scientifically gathered for the stated aim of the study. When incorporating other data sources, consideration should also be given to the registry update schedule. If external, or linked, data sources may provide values for these confounder variables otherwise not in the registry, they may ultimately help reduce bias in the analysis and interpretation of patient outcomes.

Primary market research can be quantitative or qualitative in nature. It may be expensive too. In addition, observational studies can generate as many hypotheses as they test, and secondary sources of data can be merged with the primary data collection to allow for analyses of questions that were unanticipated when the registry was conceived. A second major advantage of using secondary data is the breadth of data available. Primary data sources incorporate data collected for direct purposes of the registry i. Introduction Identification and evaluation of suitable data sources should be completed within the context of the registry purpose and availability of the data of interest. Secondary data is a second-hand information.

An example of the need for regular communication is a situation that arose with the United States Renal Data System a few years ago. The most important and remarkable advantage here is that it requires less manpower and time and as a result less costly to complete the entire procedure. These surveys calculate estimates through statistical processing of the sampled data. Secondary data is different from primary data on the basis of the sources of their collection. Death and birth records—Death indexes are national databases tracking population death data e. It is time-saving and cost-efficient: the data was collected by someone other than the researcher. The intended use of the data elements will determine whether patient-level information is required.

Sometimes it is a matter of a few Google searches to find a credible source of information. Confounders such as comorbidities disease diagnoses and conditions can confuse analysis results and interpretation of causality. The best identifier is one that is not only unique but has no embedded personal identification, unless that information is scrambled and the key for unscrambling it is stored remotely and securely. Information when collec­ted directly from the desired field for the use of a predetermined purpose is called the primary data e. Secondary data can either be qualitative, such as diaries, newspapers or government reports, or quantitative, as with official statistics, such as league tables.

Indian Textile Bulletin monthly , pub­lished by the Textile Commissioner. Examples include the actual cost of the treatment e. In comparison with primary research where you have to design and conduct a whole primary study process from the beginning, secondary research allows you to gather data without having to put any money on the table. The information may not be same as we require. Secondary data refers to which is collected by someone who is someone other than the user.
