    Study Notes

    Sources of Morbidity and Mortality Data

    • Students should be able to identify various sources of morbidity and mortality data used in public health studies and epidemiological investigations.
    • Students should be able to complete pertinent public documents related to civil registries of vital events.
    • Students should be able to identify important community health indices of public health significance.

    Sources of Data

    • Primary Data: Collected directly by the investigator for the specific study's objectives. Examples include survey data, interviews, tests, and examinations. These are crucial for answering specific research questions.

    • Secondary Data: Data collected by other researchers for different purposes, but may be helpful in the current study. Investigators have no control over data collection methods, objectives, or variable classifications. Quality may be affected.

    Reports of Occurrence of Notifiable Diseases

    • Certain diseases are legally required to be reported to health authorities.
    • Reporting is generally done weekly to monitor communicable diseases.
    • Data comes from rural health units, city health offices, provincial health offices, and municipal health offices.

    Reporting of Notifiable Diseases - Objectives

    • Reporting of notifiable diseases provides information about community morbidity.

    Epidemiologic-Prone Diseases

    • Includes a list of diseases categorized as epidemic prone (e.g., Acute Bloody Diarrhea, Acute Encephalitis Syndrome, Acute Viral Hepatitis, Anthrax, Cholera, etc.)

    Diseases Targeted for Eradication or Elimination

    • Includes a list of diseases targeted for eradication (e.g., Poliomyelitis, Measles, Neonatal Tetanus).

    Other Diseases or Conditions of Public Health Importance

    • Includes conditions of public health importance (e.g., adverse events following immunization, diphtheria, non-neonatal tetanus, pertussis, rabies).

    Elimination and Eradication

    • Elimination: Reduction to zero of a specified disease incidence in a defined geographical area due to deliberate efforts. Continued intervention is required.

    • Eradication: Permanent reduction to zero of the worldwide incidence of infection caused by a specific agent, as a result of deliberate efforts. Intervention measures are no longer needed.

    Quality of Diagnosis in Notifiable Diseases Reports

    • Diagnosis accuracy may be limited by a lack of laboratory testing facilities, especially in rural areas.

    Republic Act 11332

    • Disease control refers to reducing disease incidence, prevalence, morbidity, or mortality to acceptable levels through deliberate efforts and continuous intervention.

    • Disease response refers to actions to control the spread of infection, outbreaks, or epidemics and prevent re-occurrences. This includes, but isn't limited to, movement restrictions, partial or complete closure of schools and businesses, travel restrictions, and emergency preparation.

    Quarantine versus Isolation

    • Quarantine separates and restricts the movement of individuals that may have been exposed to a communicable disease to see if they become ill.
    • Isolation separates ill individuals from those who are healthy to prevent spread of disease.

    Disease Surveillance

    • Refers to a process of ongoing systematic collection, analysis, interpretation, and dissemination of data for planning, implementation, and evaluation of public health practice.
    • A system for data analysis and dissemination for prevention and control.

    Emerging and Re-Emerging Infectious Diseases

    • Diseases that have not occurred before in humans, or those that have occurred rarely but now have a wider impact.

    Notifiable Diseases (Category I and II)

    • Presents a categorization of notifiable diseases into immediately notifiable (Category I) and weekly notifiable (Category II) groups.

    Civil Registries of Vital Events

    • Continuous and permanent recording of vital events (births, deaths, marriages).
    • Primary use for legal documents and statistics.

    Certificate of Death

    • Legal record containing an individual's death information, and details surrounding the event.
    • Provides data for claims, inheritance, insurance benefits.
    • Provides information to family for arrangements.
    • Includes the cause of death certified by a licensed doctor
    • The physician diagnoses the cause of death.
    • Information is coded according to the International Classification of Diseases Version 11 (ICD-11) and entered into a database.
    • The consolidated mortality statistics form the basis for health policies and programs

    Uses of Death Statistics

    • Provides indicators for infectious diseases and outbreaks that need control.
    • Serves as a basis for programs to promote public safety, accident prevention and crime eradication.
    • Part of mortality surveillance, health, epidemiological research, health policy, and program planning.
    • Used in analyzing mortality rate differentials.

    Certificate of Death - Parts

    • Immediate cause: The recent condition that led directly to death.
    • Antecedent cause: The condition between the underlying and immediate cause
    • Underlying cause: The disease or injury that initiated a chain of events leading the death.

    Certificate of Death – Additional Information

    • Time interval between the onset of the cause to the death
    • Acceptable intervals for time (e.g., approximately, unknown)

    Infant Death

    • Provides data entry guidelines for infant deaths.

    Ill-Defined and Non-Specific Causes of Death

    • Vague causes of death lacking detailed information for public health.
    • A rule: Not typically used as underlying causes, unless nothing else is known

    Modes of Dying

    • Presents different modes of dying that cannot be specific causes of death. Examples include Asphyxia, Cardiac Arrest, and Coma

    Death Involving External Injuries

    • The external cause or event (e.g., a trauma) is considered the underlying cause of death.
    • The bodily trauma is the antecedent cause.
    • The fatal derangement from the bodily trauma is the immediate cause.
    • Report to the Philippine National Police (PNP) or the National Bureau of Investigation (NBI) if suspecting violence or crime.
    • Identifies violent or criminal causes of death.

    Dead on Arrival (ER)

    • Deaths occurring in the emergency room.
    • ER officer will complete certificate and provide a definite diagnosis - otherwise it goes to the medico-legal officer.

    Certificate of Live Birth

    • Information on a recorded birth
    • Gravidity and parity data

    Issues on Paternity - Illegitimate Children
