A patient has just arrived on a general medical ward. They are having difficulty breathing, refuse to eat, and have not slept for three nights. Where should you start with the data collection? Virginia Henderson’s model provides a framework for structuring observations across the physical, psychological, and social dimensions of the person receiving care.
Three sources of dependence to identify before completing the Henderson framework
It is easy to move straight to rating the needs without first asking: what is preventing this patient from meeting a particular need? Virginia Henderson identifies three sources of dependence: strength, will, and knowledge. An older person who no longer washes themselves may lack muscle strength, but they may also have lost motivation after a bereavement or be unaware of the assistive devices available.
This distinction changes the nature of the intervention. Compensating for a lack of strength (help with bathing) is very different from addressing a lack of knowledge (therapeutic education on how to use a bath board). Completing the framework without identifying the source of the difficulty results in a generic care plan. This reduces Virginia Henderson’s fundamental needs to a simple checklist, even though they are designed as a clinical reasoning tool.
In practice, noting “impaired need” in the “eliminate” box is not enough. You need to document whether the person is incontinent because of neurological impairment (strength), because they refuse to ask for a bedpan (will), or because they are unaware of pelvic floor rehabilitation exercises (knowledge).
Virginia Henderson’s physiological needs: assessment at the patient’s bedside
The first five needs cover vital functions. They are often assessed as soon as the patient is admitted, sometimes without even thinking about it. That is precisely where the risk lies: ticking boxes mechanically.
Breathing, eating and drinking, eliminating
Breathing is about more than oxygen saturation. Observe the rate and depth of breathing, and look for retractions or cyanosis. A patient receiving nebulizer treatment has an impaired need; a patient on assisted ventilation has a severely impaired need.
When assessing eating and drinking, the question goes beyond appetite. A patient who eats independently but refuses certain foods for religious reasons does not have an impaired need: they are exercising a choice. This distinction matters to avoid a biased assessment.
Elimination is assessed along two dimensions: continence and independence in getting to the toilet. A continent patient who cannot get up alone needs assistance from another person, not absorbent products.
Moving and sleeping
The need to move and maintain good posture covers both walking and the ability to reposition oneself in bed. A patient who walks with a rollator but stays seated all day for fear of falling has a need affected by a lack of will or confidence.
Sleep is assessed by its quality, not just its duration. A patient who sleeps eight hours with the help of a sleeping pill but wakes up tired does not have a met need. Frequent waking and insomnia should be documented along with their possible causes (pain, anxiety, ward noise).
Psychosocial needs: the part of the assessment that is often rushed
The remaining nine needs relate to identity, relationships, and decision-making autonomy. They are sometimes covered in a single line in the care record, even though they determine whether the patient engages with their support plan.
- Dressing and maintaining body temperature: a nursing home resident who always wears the same hospital gown despite having their own clothes may have an unmet need, often because of how the service is organized rather than an inability to dress
- Keeping clean and protecting the skin: assessment includes skin condition (pressure sores, dryness, lesions) and the person’s hygiene habits, not just their ability to wash
- Avoiding dangers: this need covers risk awareness, pain, fall prevention measures, and medication management
- Communicating: assess verbal and nonverbal expression, the ability to make oneself understood, and the ability to maintain social connections. A patient with post-stroke aphasia and a socially isolated patient both have an impaired need, but the interventions differ considerably
The final three needs (practicing one’s religion and acting according to one’s beliefs, working toward a sense of accomplishment, and recreation) are the ones caregivers document least often. Yet, under the HAS framework for ESSMS, personalizing the support plan requires that the person express their expectations and take part in developing their plan. Ignoring these needs reduces care to its technical dimension.
The need to learn completes the list. It is particularly important in therapeutic education: a patient with diabetes who does not understand how insulin works cannot manage their injections independently.
Clinical reasoning and the Henderson framework: complementary, not interchangeable
Working through all fourteen needs ensures a comprehensive assessment. It does not remove the need to prioritize. A patient experiencing respiratory distress and difficulty engaging in recreation at the same time does not need the same response for each need. The framework structures observation; clinical reasoning prioritizes interventions.
In nursing education, the focus is shifting beyond simply memorizing the fourteen headings toward developing clinical analysis skills. Knowing that the need to eliminate exists says nothing about what to do when faced with a distended bladder. Henderson’s model provides the framework, not the answer.
Experienced caregivers often use this framework without naming it, as a matter of professional instinct. For students and newly qualified nurses, systematically working through each need remains the best way to avoid missing anything, provided they identify the source of each impairment and link every observation to a specific intervention.
