Summary
Brazilian health databases like CNES, SIH, and CIH have data quality issues. Improvements are needed for better hospital planning and healthcare network decisions.
Area of Science:
- Health Services Research
- Health Informatics
- Public Health Data Analysis
Background:
- Secondary data offers advantages in speed, cost, and scope for health service research.
- Assessing the quality of health information systems is crucial for reliable research and policy-making.
Purpose of the Study:
- To identify and describe data quality problems in Brazilian hospital information systems.
- To evaluate the coverage, completeness, consistency, and validity of key health databases.
Main Methods:
- Analysis of the National Database on Health Units (CNES), Public Hospital Information System (SIH), and Private Hospital Information System (CIH).
- Exploration of data quality dimensions: coverage, completeness, consistency, and validity.
Main Results:
- Basic hospital registration data show good coverage and consistency.
- Hospitalization data completeness varies, with CIH covering 55% and SIH exceeding 100% of admissions.
- Inadequate filling of procedure and diagnosis fields is a significant issue, particularly in CIH.
Conclusions:
- Significant improvements are needed in Brazilian health databases to enhance analytical potential.
- Addressing data quality issues is essential for supporting strategic studies and informed decision-making in healthcare planning.

Hospitals offer medical and surgical care to the sick and injured, along with accommodation while they recover. At the same time, they also provide outpatient, emergency, psychiatric, and rehabilitation services to meet various community needs. In addition to providing medical care, hospitals also act as hubs for medical research and training. Hospitals use clinical procedures and evidence-based practice standards to deliver patient care. To deliver safe and efficient care, a nurse must stay up...

Hospitals provide inpatient and outpatient services. Inpatient services provide care to patients that stay in the hospital for an extended period, ranging from days to months. Examples of inpatient services include intensive care units, hospital wards, or surgeries. Outpatient services provide care to patients who come to a hospital for a diagnostic or treatment but do not stay overnight —for example, diagnostic tests, surgical procedures, or health education.

Secondary healthcare is offered by a specialist, generally in hospitals or clinics for patients referred by primary healthcare providers. It occurs when a person has an illness or injury that requires specific medical care. Secondary care is often referred to as acute care. Secondary care can range from uncomplicated care to repair a minor laceration or treat a strep throat infection to more complicated emergent care, such as treating a head injury sustained in an automobile accident.
