Differences between population-based and service-based applications in public health organizations information systems

Information systems have risen as an essential tool in the development of the health sector. Public health groups do need efficient and well-designed systems of information to make the best use of the increasing supply of related medical data (Peppard & Ward, 2016). The organizations rely on these systems to make decisions, improve various operations in areas such as epidemiologic observation, assessment programs, analysis of policies and public health planning. Service-based applications for information systems are usually used to make accessible and store service information reflecting actions being performed by the health groups and other medical-related entities (Studnicki, Berndt & Fisher, 2008).

An example includes; the routine collection of blood screening results of kids under five years of age, recording tuberculosis-based visits by the clients, immunization statuses and other data such as that of sexually transmitted diseases (Studnicki et al., 2008). This data collected can be used to reflect individual contacts and can be used to monitor the performance of the program and also describe a set of users at a particular institution.

Population-based applications usually do offer data on defined population groups and communities of interest. The latter has to integrate this data from vast sources of communities including illness surveillance systems and crucial statistics archives. An example of such is the system monitoring the notifiable diseases which offer population-wide information for approximately fifty illnesses which call for timely and useful data for effective control and prevention. Such a database is crucial as it helps conduct comparisons and analysis of trends of disease occurrences among populations (Studnicki et al., 2008).

Despite the differences between the two applications in the health sector, they can relate and complement each other. For example, service-based data can be used to construct population-based information such as the recent implementation of the immunization archives by various local public health organizations and states (Wager, Lee & Glaser, 2017).
