Sorting Through Alphabet Soup: How to Choose Assessment Tools in Palliative Care

Medicine loves its abbreviations, which are intended to streamline care but often create confusion. Early in my training, I remember wondering whether ‘OD’ meant right eye or once daily.” I later discovered palliative care found itself in a similar quandary with assessment tools. Which tools should I use? When are they helpful versus a burden? When do we over assess patients and caregivers in our efforts to leave no stone unturned?

I can easily recall a clinic visit with a caregiver and her spouse, who was living with dementia. The caregiver was experiencing significant burnout and presented to the palliative care clinic, hoping to receive support. Upon arrival, she was inundated with a variety of assessment tools in the waiting room, which stood as a barrier between her and their team of clinicians. The two arrived at the exam room, appearing frustrated and overwhelmed.

Central to delivering high-quality palliative care is the use of various assessment tools to evaluate symptoms, needs, and goals of care. These tools not only help in making informed and objective clinical decisions but also ensure that care is tailored to each individual patient’s preferences and circumstances. However, their use comes with inherent challenges, including the need for clinical judgment, cultural sensitivity, and careful consideration of the patient's circumstances. To reduce health disparities, it is essential for health care professionals to be aware of the diverse cultural, social, and economic factors that may impact the use and interpretation of these tools.

This blog explores some of the most commonly used assessment tools in palliative care, to help clinicians decide which to use and when. We will examine their advantages, limitations, and important health equity considerations to support informed and equitable clinical use—as well as obstacles.

The PHQ-2 offers a quick check-in, asking patients if they've recently experienced feeling down or lost interest in things that matter to them. It’s a gentle first step—a brief screen that helps decide if a deeper dive is needed. When more detail is helpful, the PHQ-9 builds on this by exploring a wider range of symptoms like sleep, appetite, energy, and even thoughts of self-harm. It’s a trusted way to assist in diagnosis and track depression over time.

The PHQ-4 combines the latter depression screen with two questions about anxiety, giving a rapid understanding of emotional distress in just four questions.

What’s great about these tools? They’re short and simple, easy to fit into busy clinical practices, and can be completed by patients, caregivers, or clinicians. And scoring is straightforward, making it clear when more support is needed.

But watch out for limitations. The brief versions (PHQ-2 and PHQ-4) only scratch the surface, so they’re a starting point rather than a full picture. The PHQ-9, while more thorough, takes more time, which isn’t always feasible in fast-paced settings. Patient responses can also be shaped by factors like cognitive challenges, stigma around mental health, or language and cultural differences. Without interpreting the results of these tools thoughtfully, there’s a risk of missing or misunderstanding symptoms.

Like the PHQ tools for depression, the GAD-2 offers a quick screen for anxiety using two questions to catch if anxiety might be an issue. If the patient screens in for anxiety on the GAD-2, the GAD-7 digs deeper, measuring how intense symptoms are and helping track them over time.

Why use these? The GAD-2 is fast and easy for an initial check, and the GAD-7 is well-validated for understanding severity and progress. Both have simple scoring and are widely trusted.

Limitations to keep in mind: These tools focus mostly on generalized anxiety disorder, so they might miss other forms of anxiety. They rely on self-reporting, which can be tough if patients have trouble recognizing or describing their feelings. Cultural differences can also change how symptoms show up or are reported. And like the PHQ-9, the GAD-7 requires more time, which may not always be available.

Challenges and Considerations
For patients with cognitive impairments, such as advanced dementia, self-reporting on tools like the PHQ-9 or GAD-7 can be difficult or impossible. In these cases, caregivers often step in to share observations, offering valuable insights into mood or anxiety changes. For example, a caregiver might notice behaviors like irritability or withdrawal that suggest distress.

Sometimes, non-verbal signs like body language, facial expressions, or physical symptoms (e.g., restlessness, tears) become important clues, especially when patients are near the end of life and can no longer communicate clearly. These observations help round out the picture and ensure emotional needs don’t go unnoticed.

The Charlson Comorbidity Index assigns scores to different diagnoses to estimate a patient’s risk of mortality within a year. This helps clinicians get a clearer sense of prognosis, which can guide important conversations, including advance care planning.

Imagine a patient whose goal is to walk independently again, but their prognosis suggests limited time. Knowing this gap helps the care team offer a focus shift toward achievable goals that align with the patient’s reality and desires. Being able to offer options not only helps align what’s most important but also supports patient autonomy. Following education about the likelihood of walking independently and prognosis, the patient may move forward, understanding the potential risks, or may choose to align their care with an alternate goal.

What works well here? The CCI is objective, validated across many illnesses, and useful to identify patients who might benefit from palliative care. It’s also helpful in research and population health.

But it’s not perfect: It doesn’t capture day-to-day function, symptom burden, or the social factors that hugely affect health. In underserved populations, comorbidities might be underdiagnosed, and the tool offers population-level estimates that don’t always fit every individual.

Knowing how well a patient functions day to day is crucial. These tools help track abilities and guide care decisions:

● FAST is designed for Alzheimer’s disease, helping stage cognitive and functional decline.

● Karnofsky Performance Status (KPS) scores physical function from normal (100) to deceased (0), widely used in oncology and palliative care.

● ECOG Performance Status offers a quick 0-to-5 scale for functional activity, designed with cancer populations in mind.

● Palliative Performance Scale (PPS) focuses on palliative populations, covering daily activities, mobility, intake, and consciousness; trends over time are more important than single data points

Using these tools consistently over time creates a story of how a patient’s function changes, helping the care team and family understand progression and make decisions about treatments or hospice.

Advantages: They simplify complex observations, support communication across teams, and help identify when extra support or hospice might be needed.

Limitations: Scoring can vary between clinicians, and the tools often miss cognitive or psychosocial challenges. Cultural and social factors also influence function but aren’t fully captured. PPS only offers snapshots, so it’s important to look at trends, not just one score.

Spiritual care is an essential part of holistic palliative care, yet many clinicians feel unsure how to start the conversation. The FICA tool provides a framework for a guided conversation around Faith, Importance, Community, and how spiritual needs should be addressed.

Strengths: It’s respectful, patient-centered, and quick enough for busy clinical sites. Anyone on the care team can use it to open doors to deeper conversations about what gives the patient meaning and comfort.

Challenges: Many providers lack formal training or may feel awkward discussing spirituality. Spirituality is deeply personal—some patients don’t connect with organized religion, so it takes sensitivity and openness.

Assessment tools are only as good as their fit for the people using them. Language barriers, health literacy, cultural beliefs, and stigma can all shape how symptoms are reported or understood. Social factors like poverty, racism, and housing instability affect health but often slip under the radar in traditional tools.

Clinicians can improve equity by adapting tools for diverse populations, working closely with patients and their support systems, and being mindful of their own biases. Proxy reporting and attention to non-verbal cues also help when patients can’t communicate directly.

Assessment tools are vital but come with shared challenges. Patients with cognitive impairment may struggle with self-report tools, and stigma around mental health can lead to underreporting symptoms. Tools may not always capture cultural differences or social realities affecting patients’ experiences.

To address this, clinicians can include caregivers in reporting when needed and observe non-verbal cues like body language or facial expressions to better understand distress, especially for patients nearing end of life.

Balancing thorough assessment with compassion means choosing tools thoughtfully and adapting to each patient’s context. Here are some tips:

• Use multiple, complementary tools for a comprehensive assessment.
• Consider using consistent tools over a longitudinal relationship with a patient for comparisons over time.
• Select culturally validated and linguistically appropriate versions.
• Incorporate social determinants of health screenings alongside clinical tools.
• Train staff on cultural humility and implicit bias.
• Fast-paced environments, where time is limited, can impact use of time-consuming assessment tools. Choose tools that are most relevant to the patient’s current needs. For example, if a patient is at the end stages of life, tools assessing functional decline (e.g., Palliative Performance Scale (PPS)) may be more appropriate than comprehensive symptom inventories.
• Ensure that assessment results are not only documented but lead to actionable decisions. Tools like PPS can be used to trigger conversations about hospice care eligibility.
• Combine Tools: For example, the PHQ-9 and GAD-7 can be combined into a single emotional health screening that is quicker to administer, allowing for a broad but efficient evaluation of mood and anxiety without adding unnecessary time to the visit.
• Engage and educate patients and caregivers to understand context and preferences.
• Advocate for ongoing research and tool adaptation to enhance equity.

Assessment tools like the PHQ series, GAD scales, Charlson Comorbidity Index, functional status assessments, and spiritual history guides each play an important role in palliative care. When used thoughtfully, with an eye toward equity and patient-centeredness, they help clinicians provide compassionate, tailored care.

Remember the caregiver and spouse overwhelmed by multiple assessments — their experience reminds us to choose tools wisely, explain their purpose clearly, and integrate them seamlessly into care. When patients and clinicians partner around assessment, they can better align treatment with what matters most, ultimately enhancing quality of life.
