• Simplifying Access

• Enhancing Control

• Facilitating Updates

• Improving Communication

Role of Function of HIS:

Simplifying Access

Role of Function of HIS:

• HIS eliminates the need for cumbersome paper files, making patient information readily accessible.

Enhancing Control

Role of Function of HIS:

• Access is controlled through authorizations, ensuring that only authorized personnel can view, update, or modify patient data. This strengthens data security and privacy.

Facilitating Updates

Role of Function of HIS:

• Electronic medical records (EMRs) allow for easy updating and review of patient information. Copies can be readily provided to patients upon request.

Improving communication

Role of Function of HIS:

• HIS facilitate communication between healthcare providers and institutions, although strict confidentiality protocols are crucial to protect patient privacy and security.

• Health Information System Resources

• Indicators

• Data Sources

• Data Management

• Information Products

• Dissemination & Use

Components of HIS:

Health Information System Resources

Components of HIS:

• This includes the legislative, regulatory, and planning frameworks, along with essential resources like personnel, financing, logistics, ICT, and coordinating mechanisms.

Indicators

Components of HIS:

• A core set of indicators and targets across health determinants, system inputs/outputs/outcomes, and health status forms the basis for HIS planning.

Data Sources

Components of HIS:

• These can be population-based (censuses, civil registration, surveys) or institution-based (individual/service/resource records). Other sources like health surveys, research, and community-based information also contribute.

Data Management

Components of HIS:

• Encompasses all aspects of data handling, from collection and storage to quality assurance, flow, processing, compilation, and analysis. This includes defining requirements for periodicity and timeliness.

Information Products

Components of HIS:

• Raw data is transformed into meaningful information, forming the basis for evidence-based health action.

Dissemination & Use

Components of HIS:

• Information value is maximized by ensuring accessibility to decision-makers, addressing behavioral/organizational constraints, and incentivizing information use.

Demographic Data

Different Data Sources for HIS:

• Basic facts about individuals, such as age, gender, race/ethnicity, marital status, address, family information, employment, and education

Administrative Data

Different Data Sources for HIS:

• Information related to healthcare services provided, including diagnostic tests, procedures, charges, payments, provider type/specialty, and institution type (hospital, clinic, etc.).

Health Risk Information

Different Data Sources for HIS:

• Data on lifestyle and behavior (e.g., tobacco use, exercise), family history, and genetic factors that may influence disease risk.

health status

Different Data Sources for HIS:

• Self-reported information on physical, mental, emotional, cognitive, and social functioning, as well as perceptions of current and future health.

Patient Medical History

Different Data Sources for HIS:

• Data on past medical encounters, including hospitalizations, surgeries, pregnancies, previous medical problems, and family history.

Current Medical Management

Different Data Sources for HIS:

• Information from encounter forms and patient records, including health screenings, current health problems, diagnoses, allergies, procedures, lab tests, medications, and counseling.

Outcomes Data

Different Data Sources for HIS:

• Measures of the effects of healthcare and the consequences of health problems. This can include readmissions, complications, side effects, and patient satisfaction. Ideally, outcomes are assessed over time through patient reports (Donaldson and Lohr, 1994).
