Health Assessment, Part One: Health History Assessment

Jessica Best and Amy McCrystal

Learning Outcomes

In this chapter you will learn how to:

  • Identify the key components of a health history
  • Demonstrate effective techniques for conducting a health history.

The Health History

The complete subjective health assessment is commonly referred to as a health history. It provides an overview of the patient’s current and past health and state of illness. You conduct it by interviewing the patient, asking them questions, and listening to their narrative.

This information is often shared verbally with you or in a way that the patient can best communicate. It is also sometimes collected through a standardised form that the patient completes. In some cases, it also includes information shared by a family member, friend, or another health professional when the patient is unable to communicate.

The complete subjective health assessment is part of the assessment step and first component of the Care Planning Process (assessment, problem identification, planning interventions, implementing interventions and evaluating outcomes).

A circular model of a nursing process containing five steps: Assessment, problem identification, planning interventions, implementing interventions, and evaluating outcomes. Each step is displayed as an equal portion in a donut shape with arrows that lead in a clockwise direction. The top ‘assessment’ step is raised and clearer than the other faded steps. A smaller subjective and objective portion is connected to this assessment step.
Figure 1. The subjective and objective assessment types as part of the care planning process

As illustrated in Figure 1, the assessment phase of the Care Planning Process involves collecting subjective data (information that the patient shares) and objective data (information that you collect when performing a physical exam).

Subjective and Objective Data

As the word “subjective” suggests, this type of data refers to information that the patient voluntarily shares with you, either spontaneously or in response to your questions. Subjective data can include information about both symptoms and signs. In the context of subjective data, symptoms are experiences that the patient feels and you would only know about them if the patient discloses them to you. Signs, on the other hand, observable by the nurse, such as a rash, bruising, or perspiration. Although signs can be observed, they fall under subjective data when the patient provides additional context. For example, the nurse may observe a rash and the patient may state that the rash is itchy, this would be considered subjective data. In this case, the rash is a sign, but the itching is a symptom as it is something the patient feels and cannot be directly observed by the nurse.

Categories

Categories of the complete subjective health assessment (as illustrated in Figure 2) vary depending on the framework you follow but generally include:

Two rows of coloured circles containing icons representing the subjective assessment categories. On the top row from left to right, the categories are: Demographic and biographic data, main health needs, current and past health, and mental health. On the bottom row from left to right, the categories are functional health, preventative treatments and examinations, family health, and cultural health.
Figure 2. Subjective assessment categories

The assessment begins with an introduction, followed by the collection of demographic and biographic data, as well as the patient’s primary health needs. After this initial stage, there is no fixed order in which other categories must be assessed. The sequence often depends on the patient’s main health concerns or reasons for seeking care and may also be influenced by the natural flow of conversation. Sensitive topics and culturally relevant health questions are generally addressed later in the assessment once a level of trust has been established with the patient.

When introducing yourself, always state your full name, designation, and pronouns, and then ask the patient which name and pronouns they prefer you to use. It’s important to note that the term “preference” should not be used when referring to pronouns and gender, as these are not simply preferences.

In addition to the general categories, you may include subjective questions related to each body system in a phase known as the Review of Systems. These questions provide valuable insight into the function and condition of various systems (e.g., skin, eyes, cardiovascular, musculoskeletal). Depending on the patient’s responses and any cues that raise concerns, you may need to ask follow-up questions for further clarification.

Demographic and Biographic Data

Introductory information refers to the demographic and biographic data that you collect from the patient. This data provides you with basic characteristics about the patient, such as their name, contact information, birthdate and age, gender, gender pronouns, allergies, languages spoken and preferred language, relationship status, occupation, and resuscitation status. While this data is concise, the intent of collecting it is meant as a brief overview of the patient. This data provides you with basic characteristics about the patient, such as their name, contact information (including next of kin in an emergency) and any allergies to be aware of.

 

Contact information and emergency information

  • What is your full name? What name do you prefer to be called by?
  • What is your address?
  • What is your phone number?
  • Who can we contact in an emergency? What is their relationship to you? What number can we reach them at?
 

Birthdate and age

  • What is your birthdate?
  • What is your age?
 

Gender

  • Tell me what gender you identify with.
  • Not everyone uses a gender pronoun, but if you do, what gender pronouns do you use? (If the person asks you to use a pronoun that you are not familiar with, it is okay for you to respectfully respond, “I am not familiar with that pronoun. Can you tell me more about it?”)
 

Allergies

  • Do you have any allergies?
  • If so, what are you allergic to?
  • How do you react to the allergy?
  • What do you do to prevent or treat the allergy?

Note. You may need to prompt for information on medications, foods, insects, etc.

 

Languages spoken and preferred language

  • What languages do you speak?
  • What language do you prefer to communicate in (verbally and written)?

Note. You may need to inquire and document if the patient requires an interpreter.

 

Relationship status

  • Tell me about your relationship status.

Note. Avoid questions such as “Are you married?” or “Do you have a boyfriend?” or “Do you have a wife?” as they assume normative behaviour and heterosexuality.

 

Occupation/school status

  • What is your occupation? Where do you work?
  • Do you go to school?

Note. Reassure the patient that this information provides insight into the nature of their work (e.g., the physical or psychological impact) and environmental exposures and that the question is not intended to evaluate the patient.

 

Resuscitation status

We ask all patients about their resuscitation status, which refers to medical interventions that are used or not used in the case of an emergency (such as if your heart or breathing stops). Reassure the patient that it is okay to take more time to think about this, and that they may want to speak with someone they trust like a family member or friend. You should also make it clear that they can change their mind. A discussion might include questions such as: “At this point, if any of this happens, would you like us to intervene?”

Note. Depending on the patient’s answer, you will need to collaborate with the broader healthcare team, explore the details of the patient’s wishes further, and have them complete a requisite resuscitation form, depending on your organisational policy.

 

Main Health Needs (Reason for Seeking Healthcare)

The patient’s main health needs are referred to in a variety of ways depending on the environment or institution that you work in. At the first point of contact, “main health needs” are often referred to as “reasons for seeking care” or “main concerns or issues.” In an institution where the patient is already admitted, “main health needs” is more commonly used. Whichever term is used, it recognises that patients are complex beings, with potentially multiple co-existing health needs, and often there is a pressing issue that requires most immediate care. This is not to suggest that other issues be ignored, but rather it allows providers, patients, and care partners to stay focused. See below for an example of how you might ask a patient about their main health needs.

   

Patient is presenting to a clinic or a hospital emergency or urgent care (first point of contact)

  • Tell me about what brought you here today.
    • Tell me more.
    • How is that affecting you?

 

Patient is already admitted, and you are starting your shift

  • Tell me about your main health concerns today.
    • Tell me more.
    • How is that affecting you?

Current and Past Health

Understanding the patient’s current and past health is important and may provide an explanation or rationale for the patient’s current health status. Furthermore, these data can provide insight into health promotion needs and co-morbidities. It is helpful to understand the current and past health profiles before assessing other aspects of health, as the information will inform subsequent questions. The order of the questions about current and past health, and the detail elicited, often depends on the patient’s main health needs and developmental status. Not all questions apply to every patient; their use and phrasing are contingent on the individual patient and their situation. As you develop your clinical judgment, which comes with practice, you will become more astute about which questions are appropriate and how to frame these questions. Sample questions are provided below for assessing current and past health, but other questions may arise that you may need to ask depending on the patient’s main health needs and their responses.

 

Current health

Issues other than their previously noted main health needs/reasons for seeking care.

  • Are there any other issues affecting your current health?
    • Tell me more.
    • How is that affecting you?

Note. Although the patient may not have made the connection, other health issues are sometimes related to their main health need. For example, they may report a fever in addition to an earache.

 

Childhood illnesses

Type, timing, treatment, hospitalisations, complications, disability

  • Tell me about any significant childhood illnesses that you had.
  • When did it occur?
  • How did it affect you?
  • How did it affect your day-to-day life?
  • Were you hospitalised? Where? How was it treated?
  • Who was the treating practitioner?
  • Did you experience any complications?
  • Did it result in a disability?

Note. The probing questions may be more important to ask when the illnesses may impact the patient later in life, for example, Rheumatic Heart Disease (RHD).

 

Chronic illnesses

Type, timing, impact, treatment, hospitalisations, complications, disability

  • Tell me about any chronic illnesses you currently have or have had (e.g., cancer, cardiac, hypertension, diabetes, respiratory, arthritis.

Note. Chronic illnesses can significantly impact a patient’s life both physically and psychosocially.

 

Acute illnesses, accidents, or injuries

Type, timing, treatment, hospitalisations, complications, disability

  • Tell me about any acute illnesses that you have had.
  • Tell me about any accidents or injuries you currently have or have had.

Note. Acute and Chronic illnesses can significantly impact a patient’s life both physically and psychosocial.

Obstetrical health

Number of pregnancies, full-term deliveries, pre-term deliveries, number of living children, fertility treatments, miscarriages, termination of pregnancy, and other data related to current or past pregnancy

  • Have you ever been pregnant?
  • Do you have plans to get pregnant in the future?
  • Tell me about your pregnancies.
  • Have you ever had difficulty conceiving?
  • How was your labour and delivery?
  • Tell me about your postpartum experience.
  • Were there any issues or complications?

Note. These questions do not apply to all patients. Additionally, you should be aware that the feelings about pregnancy can be complex and may not always be happy.

 

Mental Health and Well-Being

A patient’s mental health refers to their emotional and psychological well-being that affects their day-to-day functioning. Mental health is often under-screened, which reveals a significant gap, considering that stress is pervasive in society. Mental illness includes conditions such as depression, anxiety, addiction, schizophrenia, and post-traumatic stress disorder, among others. Mental illness is a disruption in everyday function, which means a person’s employment, relationships, and civil participation can all be impaired by mental illness. It is important to assess a patient’s mental health, and if present, mental illnesses. You want to begin this component of the assessment with a statement such as, “Mental health is an important part of our lives and so I ask all patients about their mental health and any concerns or illnesses they may have.”

See below for a selection of questions and statements that you may ask patients to elicit data about their mental health. Note also that there are many other factors that influence mental health, such as violence and trauma, which are addressed under the next section, Functional Health.

 

Tell me about your mental health

This question broadly focuses on health and invites a dialogue. The statement should not be asked in isolation or as a one-off question, as societally and culturally there are different meanings of what constitutes mental health, and a patient may not identify themselves as having mental health issues. If a patient responds “Good,” consider probing a bit further with “Tell me about how so,” or “What do you mean by good?” which allows them to respond in more depth.

Tell me about the stress in your life

Stress, by and large, is a relatable term that many patients have experienced and that is something they are likely more comfortable talking about than more difficult health issues because it is so ubiquitous. It’s important to be attentive to the patient’s language and consider terms they may use, such as “extreme stress,” “severe stress,” “unmanaged stressed,” or “debilitating stress,” as these may indicate an underlying mental health issue or stress that requires intervention.

How does stress affect you?

Understanding how stress affects the patient provides insight into the mental, physical, and social impact on them. You may need to probe about how stress affects the patient physically, mentally, and socially.

How do you cope with this stress?

This question invites discussion about coping strategies. It is important to be attentive to any self-harm coping strategies such as substance abuse, isolation/disengagement, food restriction, purging, cutting, compulsions, and phobias as these could indicate a mental health issue.

 

Functional Health

Functional health involves the assessment of the patient’s physical and mental capacity to participate in day-to-day activities. It includes assessment of:

  • Activities of Daily Living (ADL) are basic tasks fundamental to everyday functioning (e.g., hygiene, elimination, dressing, eating, ambulating/moving).
  • Instrumental Activities of Daily Living (iADL) are more complex daily tasks that allow patients to function independently (e.g., managing finances, paying bills, purchasing and preparing meals, managing one’s household, taking medications, facilitating transportation). Assessment of iADL may be particularly important to inquire about with adolescents or young adults who have just moved into their first place and patients who are older and/or have disabilities.

It is important to assess functional health because the data collected could expose an opportunity for preventive action and health promotion, palliation, or assistance. Because health extends beyond the absence of disease, it is important to consider broader dimensions of health as a holistic and complete assessment. You may start this section of the interview by saying, “Next, I would like to ask you some questions related to your day-to-day life and factors that affect your ability to function in your day-to-day life.” Different questions and considerations on functional health are presented below.

 

Nutrition

Refers to food and fluid intake, financial ability to purchase food, time and knowledge to prepare and make meals, and appetite or change in appetite. You also want to elicit data related to a patient’s usual diet and goals related to their nutrition. Additionally, you need to probe so that an adequate amount of detail is obtained.

 

 

 

Elimination

Refers to the removal of waste products through the urine and stool. Healthcare providers refer to urinating as “voiding.” A stool is referred to as a “bowel movement.” You want to assess urine concentration, frequency, and odour. For stool, you want to assess frequency, colour, and consistency. You want to use terminology that patients understand. Thus, you may find yourself using less medicalised terms, such as “pee” and “poo” when speaking with some patients.

 

 

 

Sleep and rest

Refer to a patient’s pattern of rest and sleep and any associated routines or aids. Although it varies for everyone, it is suggested that people should get approximately eight hours of sleep per night.

 

 

 

Mobility, activity, exercise

Mobility refers to a patient’s ability to move around (e.g., sit up, sit down, stand up, walk).
Activity and exercise refer to informal and/or formal activity (e.g., walking, swimming, yoga, strength training).

Note: In addition to exercise, it is important to assess activity because some people may not engage in exercise but still have an active lifestyle (e.g., walking to school, working in a physically demanding job).

 

 

 

Violence and trauma

There are many types of violence, including abuse and neglect, physical, sexual, psychological, and financial. Trauma can be a result of violence or other distressing events in a life.

 

 

 

Relationships and resources

Refer to influential relationships in the patient’s life, whether positive or negative.

 

 

 

Intimate and sexual relationships

Refer to sexual feelings, attractions, and preferences toward other people. It involves a combination of emotional connection and, physical companionship (holding hands, hugging, kissing) and sexual activity. It is also linked with a person’s identity and part of their physical and mental health.

 

 

 

Substance use

Refers to the intake of alcohol, tobacco products (e.g., smoking, chewing tobacco), cannabis, or any illegal drugs (e.g., cocaine, heroin, meth, inhalants, fentanyl). Assess the type, frequency, quantity, and patterns while making a distinction between use and abuse. Substance misuse typically constitutes a disruption in everyday function because of a dependence on a substance (e.g., loss of employment, deterioration of relationships, loss of home or precarious living circumstances).

 

 

 

Environmental health and home/occupational/school health

Environmental health refers to the safety of a patient’s physical environment, which is a determinant of health. Examples include exposure to community violence, air pollution, and insect infestations. This may include health and safety in the school and workplace (e.g., hazardous materials, noise, body mechanics).

 

 

 

Self-concept and self-esteem

Self-concept refers to all the knowledge a person has about themselves that makes up who they are (i.e., their identity). Self-esteem refers to a person’s self-evaluation of these items as being worthy or unworthy. It is best to assess these items toward the end of the interview because you will already have collected data that potentially contributes to an understanding of the patient’s self-concept and self-esteem.

 

 

 

Other iADL

Refers to more complex daily tasks that allow patients to function independently.

 

Preventative Treatments and Examinations

Assessing other preventative treatments and examinations includes gathering data on medications, examination and diagnostic tests, and vaccinations.  You might begin this section by asking the patient, “What are the ways that are most important for you to optimise your health?” (you may have already discussed this as part of the functional health section).

It is important to ask the patient about their current, past, and known future medication regime, examinations, and vaccinations to form a profile of the treatment that the patient has received and plans to receive. This information will tell you a lot about the patient’s current health status based on the care they have and will receive.

 

Medications

Name, dose, frequency, reason for taking it, when they first started taking it, and whether they take it as prescribed. This applies to both prescribed and over-the-counter medications, such as vitamins, pain relievers, homeopathic medicines, and cannabis.

 

 

 

Examination and diagnostic dates

Primary care provider (physician or nurse practitioner), specialists, blood pressure, blood tests, chest radiographic, electrocardiogram, dental, vision, or hearing.

 

 

 

Vaccinations

Type, date received, and any significant reactions.

 

Family Health

Assessing the current and past health of a patient’s family is important because diseases sometimes have a genetic component. This data provides you with a risk profile for inherited conditions. While it is important to understand the risk and likelihood of illness based on family health, these factors do not determine health and wellness. You want to ask questions that elicit information about the health status, age, and if applicable, cause of death and age at the time of death of blood relatives (parents, grandparents, siblings, children, nieces, nephews). Questions to ask include:

 
  • Tell me about the health of your blood relatives.
    • Do they have any chronic or acute diseases (e.g., cardiac, cancer, mental health issues)?
    • Of any blood relatives who have passed away, do you know the cause of death?
    • And at what age did they pass?

 

You also want to assess the health status of non-blood relatives and individuals that patients have had close encounters with or live with; this can be an important part of the assessment, particularly in terms of communicable diseases (i.e., diseases spread through air, food, physical contact, contaminated surfaces, and insect and animal bites). Questions to ask include:

 
  • Tell me about the health status of those you live with.
    • Has anyone been sick recently?
    • If so, do you know the cause?
    • What symptoms have they had?
  • Have you been around anyone else who was sick recently (e.g., at work, at school, in a location that involved a close encounter such as a plane or an office)?

 

Cultural Health

Assessing cultural health involves gathering data on factors related to a person’s cultural background that may influence their health and illness status. An open-ended question allows the patient to share what they believe to be most important.

 

An example

You may ask, “I am interested in your cultural background as it relates to your health. Can you share with me what is important about your cultural background that will help me care for you?”

Note. It is best to let patients spontaneously answer this question. Give them time to think. You should explore any factors that they choose to share (e.g., “Tell me more.” “How does that affect your health and illnesses?” “Is there anything else you want to share about how these factors act as resources in your life?”.

 

Assessing cultural health once meant having a checklist about different cultural groups. This approach is antiquated because it assumes culture is static and measurable. It is important to encourage each patient to speak about what is important to them. You may find that patients speak about information related to how they grew up and their way of life, their values and beliefs, traditions related to food, and their spirituality or religion, among many other things.

Key Takeaways

  • A subjective health assessment (health history) is the first step in the Nursing Care Planning Process, gathered through patient interviews and active listening.
  • It includes demographic and biographic data, main health needs, current and past health history, mental health, functional health, preventative treatments and examinations, and family and cultural health.
  • Demographic and biographic data provides essential details like name, age, gender, contact information, pronouns, allergies, languages, and resuscitation status.
  • Main health needs focus on the patient’s primary reasons for seeking care or their main concerns.
  • Understanding a patient’s current and past health helps explain their present health status and guide care planning.
  • Mental health reflects the patient’s emotional and psychological well-being, impacting daily functioning.
  • Functional health evaluates the patient’s ability to perform activities of daily living (ADLs) and instrumental ADLs (iADLs).
  • Preventative treatments and examinations involve assessing medications, screenings, diagnostic tests, and vaccinations.
  • Family health history helps identify genetic risks and inherited conditions, shaping the patient’s health profile.
  • Cultural health includes factors from the patient’s cultural background that may influence their health and care preferences.
