Logic of distribution into health groups
The classification material is based on the principle of a sequential increase in the severity of the patient's condition. The pediatrician evaluates the presence of chronic pathology in the child, as well as how effectively the body copes with existing disorders. The distribution logic is strictly structured from absolute norm (Group I) to severe conditions accompanied by pronounced functional decompensation and disability (Group V). Thus, the gradations allow for a clear distinction between healthy patients and those requiring dynamic follow-up, drug support, or continuous treatment.
| Group | Presence of chronic disease | Degree of functional compensation | Features |
|---|---|---|---|
| I | Absent | Absolute norm | No defects or deviations |
| II | Absent | Functions preserved | Reversible shifts, frequent ARVI |
| III | Present | Compensation | Stable remission |
| IV | Present | Subcompensation | Unstable remission, therapy required |
| V | Present | Decompensation | Complications, disability |
Characteristics of health groups I and II (Norm and risk)
These two groups unite children who have a complete absence of chronic diseases.
Group I (Absolutely healthy children) This category includes patients with no pathological deviations. Their physical development and neuropsychiatric status fully correspond to the established age norm. An important and mandatory condition for inclusion in the first group is the absolute absence of any anatomical defects, as well as any functional or morphofunctional deviations.
Group II (Risk group / Children with functional deviations) Chronic pathology is also absent in this group, but there are certain risk factors or reversible changes:
- Reversible functional or morphofunctional shifts are present.
- The group includes convalescents after infectious diseases (moderate and severe forms).
- Patients with identified nutritional status disorders (marked weight deficit or, conversely, excess body weight).
- Children with signs of delayed physical development, under the strict condition that this delay is not associated with endocrine system pathology.
- Children who are prone to frequent and prolonged acute respiratory viral infections (ARVI).
- Patients with the consequences of past injuries or surgical interventions, but exclusively under the condition of complete preservation of all body functions.
Characteristics of groups III, IV, and V (Chronic pathology)
These groups include patients with already established chronic diseases. The division occurs depending on the phase of the disease and the degree of functional impairment.
Group III (Chronic pathology in the compensation stage) This includes patients with chronic diseases who are in a stage of stable clinical remission. The functions of the affected organs and systems are either fully preserved or adequately compensated by the body itself. This group also includes children with diagnosed physical defects or the consequences of injuries and surgeries, in whom body functions remain fully compensated.
Group IV (Chronic pathology in the subcompensation stage) Characterized by the active phase of chronic diseases or a stage of unstable remission. Organ functions are preserved only partially (subcompensation state). This same category includes diseases in remission, but which are accompanied by marked functional impairment, requiring the mandatory prescription of maintenance pharmacotherapy. This also includes the consequences of injuries, surgical results, and physical defects with incomplete compensation of lost functions.
Group V (Chronic pathology in the decompensation stage) The group with the most severe clinical prognosis. It includes patients with an extremely severe course of chronic pathology: remissions in such children are rare, exacerbations occur frequently, and the disease itself is continuously relapsing. Pronounced functional decompensation is observed, severe complications develop that require constant and continuous treatment. Physical defects or the consequences of injuries in this case lead to significant limitations in the child's capabilities. All disabled children automatically fall into this group.
The groups can be easily remembered by their key state: I — absolutely healthy, II — risk and reversible deviations, III — pathology is present but compensated (remission), IV — subcompensation (unstable remission and therapy needed), V — complete decompensation (complications, disability).
Class and exam questions
What is the main difference between Group III and Group IV?
In Group III, the chronic disease is in stable remission, and functions are fully compensated. In Group IV, remission is unstable (or in an active phase), functions are subcompensated (only partially preserved), and maintenance therapy is often required.
Which group do disabled children belong to?
All disabled children belong exclusively to health group V, since their condition is characterized by severe functional decompensation and significant limitations of capabilities.
Can a child be assigned to Group I if they frequently suffer from ARVI?
No, children prone to frequent and prolonged acute respiratory viral infections belong to health group II (risk group) because they have functional deviations.
