The foundation of an effective healthcare plan rests upon the accuracy and depth of a patient's health history. This critical process, primarily conducted during the Assessment phase of the nursing process, serves as the primary mechanism for gathering the subjective data necessary to promote health, address acute problems, and minimize chronic conditions. By synthesizing a patient's past medical experiences, family genetic risks, and current lifestyle factors, healthcare providers can collaboratively create a tailored care plan that maximizes a patient's overall functioning.
The Nature of Health History Data: Subjective vs. Objective
Understanding the distinction between subjective and objective data is paramount for accurate clinical documentation and patient safety.
Subjective Data: The Patient's Perspective
Subjective data consists of information obtained directly from the patient and, in some cases, their family members. This data is characterized as a symptom because it is reported by the individual rather than observed by the clinician. Subjective data provides essential cues regarding a patient's functioning and identifies unmet needs that require clinical assistance.
When documenting subjective data in a progress note, professional standards require the use of quotation marks to indicate the patient's own words. Documentation should begin with specific verbiage such as: - "The patient reports..." - "The patient's wife states..."
An example of subjective data is a patient stating, "I feel dizzy."
Objective Data: The Clinician's Observation
In contrast to subjective reports, objective data is information that the healthcare provider observes directly through the four primary senses: sight, hearing, smell, and touch. While subjective data tells the provider how the patient feels, objective data provides the clinical evidence of the patient's physical state.
Sources of Information in Health History
To build a complete clinical picture, nurses and providers must navigate various sources of information, identifying who provides the most reliable data for specific needs.
Primary Sources
The patient is always considered the primary source of subjective data. Their self-reporting of symptoms, perceptions of illness, and life processes is the gold standard for establishing the "Chief Complaint" and the history of the present illness.
Secondary Sources
When the patient is unable to provide a full history or requires supplementation, secondary sources are utilized. These include: - The patient's existing medical chart. - Family members. - Other members of the healthcare team.
The Role of Care Partners
Care partners are family members or friends actively involved in the patient's care. Common examples include parents for children, spouses for one another, or adult children caring for aging parents. Care partners often contribute vital information regarding the patient's health needs and daily functioning.
However, strict clinical boundaries must be maintained regarding the use of care partners: - Care partners should not interpret for the patient. - Patients may have health problems they wish to keep private from their care partners. - Care partners may lack knowledge of medical terminology, which can lead to dangerous miscommunications. - If information is gathered from anyone other than the patient, the nurse must explicitly document the source of that information.
Comprehensive Components of a Health History
A comprehensive health history is a specialized task performed by a registered nurse and cannot be delegated. It is typically conducted upon admission to a healthcare agency or during an initial visit to a provider. The following components form the core of an exhaustive health history.
Demographic and Biological Data
This initial section establishes the identity of the patient and basic biological markers. It provides the context for the patient's age, gender, and background, which can influence the risk factors associated with various diseases.
Reason for Seeking Healthcare (Chief Complaint)
The chief complaint is the primary reason the patient is seeking medical attention. To ensure an accurate diagnosis, this section must include: - The onset date of the symptoms. - A detailed description of the symptoms (e.g., pain level and frequency). - Notes on factors that improve or worsen the condition.
Current and Past Medical History (PMH)
The Past Medical History section is essential for identifying underlying health risks and chronic conditions. This includes: - Chronic illnesses (e.g., diabetes, hypertension). - Surgical history, including the types of surgeries and the dates they were performed. - History of hospitalizations. - Previous treatments received for past illnesses.
Medications, Supplements, and Allergies
This section is critical for avoiding drug interactions and prescribing conflicts. Documentation must be precise, covering: - Current medications: Name, dosage, and frequency. - Supplements: Any vitamins, herbs, or over-the-counter aids. - Discontinued medications: Which drugs were stopped and the specific reasons for stopping them. - Allergies: Drug, food, and environmental allergies, including the severity of the reaction.
Family Health History
Family history focuses on the immediate family to identify genetic risks and inform preventive measures. This involves documenting: - Major health conditions (e.g., heart disease, cancer, mental health issues). - Hereditary conditions (e.g., diabetes, genetic disorders).
Functional Health and Activities of Daily Living (ADL)
Nurses assess a patient's ability to function independently. A key component of this is the evaluation of Instrumental Activities of Daily Living (IADLs).
| IADL Category | Description of Complex Daily Tasks |
|---|---|
| Financial Management | Managing finances and paying bills |
| Nutrition | Purchasing and preparing meals |
| Household Maintenance | Managing one's household |
| Health Management | Taking medications correctly |
| Mobility | Facilitating transportation |
Review of Body Systems (ROS)
The Review of Systems is a systematic approach to checking for symptoms in different parts of the body. While a comprehensive ROS covers all systems, specialists may focus only on relevant systems, such as the cardiovascular or musculoskeletal systems, to avoid redundant testing.
Holistic Integration: Social, Mental, and Specialized Care
Modern nursing adopts a holistic approach, recognizing that physical health is inextricably linked to emotional, spiritual, and psychosocial factors.
Social History and Lifestyle Factors
The social history outlines factors that influence health outcomes and the effectiveness of treatment plans. Key areas of documentation include: - Lifestyle habits: Smoking, alcohol consumption, and recreational drug use. - Daily habits: Exercise routines and dietary patterns. - Environment: Occupational details and living conditions.
Mental Health History
Mental health must be integrated into overall care because conditions like depression and anxiety can weaken the immune system and hinder a patient's ability to adhere to a treatment plan. This section includes: - Psychiatric diagnoses. - History of therapy. - Current mental health medications. - Stress levels and coping mechanisms.
Specialist and Provider Coordination
To ensure a seamless continuum of care, the health history must list all other healthcare providers and specialists involved in the patient's treatment. This requires documenting: - The name of the provider/specialist. - The date of the last visit. - The specific reasons for follow-up care.
Tailoring Health History to Care Settings
The depth and focus of a health history vary depending on the clinical environment.
| Setting | Primary Goal | Key Focus Areas |
|---|---|---|
| Primary Care | Establish a baseline for ongoing care | Broad overview, chronic conditions, genetic risks, and lifestyle/social history |
| Specialist Care | Targeted assessment of specific conditions | Chief complaint, HPI, focused Review of Systems (ROS), and potential diagnostic tests |
| Emergency Care | Immediate, life-saving decision making | Rapid access to the most relevant, critical medical information |
Clinical Application and Documentation Standards
The process of obtaining a health history is more than a checklist; it is a clinical skill that combines interview techniques with a general survey of the patient.
Interview Techniques
Nurses use a combination of directed, focused interview questions and open-ended questions. Open-ended questions are particularly valuable for obtaining the patient's perceptions of their illness and life processes, allowing the patient to describe their experience in their own words.
Inclusive Care and Terminology
In providing a comprehensive health history, providers must be inclusive of all patient identities. This includes utilizing an understanding of the LGBTQ umbrella term, which refers to people diverse in gender identity and sexual orientation (lesbian, gay, bisexual, transgender, and queer). Recognizing these identities is essential for providing psychosocial support and ensuring that the patient's social history is captured accurately and respectfully.
Relationship to the Medical Record
While the nurse completes the health history, the "History and Physical" (H&P) documentation in the medical record is completed by a healthcare provider upon admission. These two documents are very similar. Reading the H&P is highly beneficial for the nursing staff to gain an overview of the provider's treatment plan and ensure the nursing care plan is aligned with the overarching medical goals.
Conclusion
The health history serves as the foundational map for all subsequent clinical interventions. By meticulously collecting subjective data from primary and secondary sources, focusing on both the physical and psychosocial dimensions of health, and tailoring the approach to the specific care setting, healthcare providers can ensure patient safety and optimize health outcomes. The transition from gathering a "Chief Complaint" to evaluating "Instrumental Activities of Daily Living" allows for a holistic understanding of the patient, moving beyond the immediate illness to understand the person within their family and community context.
