Patient Centered Assessment Method


The Patient Centered Assessment Method (PCAM) is a tool medical practitioners can use to assess patient complexity using the social determinants of health that often explain why some patients engage and respond well in managing their health while others with the same or similar health conditions do not experience the same outcomes.

Understanding the patient’s health and wellbeing (lifestyle behaviors, impact of their physical health on their mental health, their ability to enjoy daily activities), their social environment (status of employment, housing, transportation, social networks), and their health literacy and communication skills (understanding of their symptoms and risk factors, language and cultural differences, learning difficulties) may indicate other factors that are affecting the person’s ability to manage their health.

Patient complexity may be due to multiple chronic medical conditions or to due social and environmental factors. It is very likely a combination of both. Factors that interfere with a patient’s usual care and decision-making can make providing health care more difficult and complex and can impact the patient’s health and recovery. As a provider, learning these factors and addressing them as part of the patient’s medical care holds promise for improving patient health and improving patient-provider relationships.

The PCAM is a systematic tool to identify these factors and their impact on patients. It offers providers a method to better understand their patient’s needs beyond their medical condition(s). It is action-oriented with the final section focused on the actions that can be taken to address the needs and issues identified in the assessment as well as the level of service coordination needed to ensure referrals can be practically accessed by the patient.

Our Goal

A program of work on the implementation, impact on health outcomes and validation work is ongoing. This website is under ongoing development and will be periodically updated with key links to peer-review articles, research reports and materials to support training.

How to Use PCAM

PCAM is copyrighted, and the developer team is committed to it being freely available for use.  PCAM is best implemented with the support of training for clinicians, and consideration of how systems support the integration of the tool.

Our Training & Resources section contains a number of resources and training tools you can download and use for your training and implementation. We are available to consult with you as you consider your implementation of the PCAM tool in your practice.

Current Research

PCAM (then called MECAM) was tested in the context of a preventative screening program in Scotland. This mixed methods prospective cohort study undertook face validation testing, conducted preliminary external validity testing, piloted implementation, and conducted a case study in a population of known complexity.  Three primary care sites in areas of high deprivation in Scotland participated.  The research found PCAM offered much promise as an assessment of complexity that identifies biopsychosocial complexity, and supports clinician decision making to address those needs. With training and practice it can be easily integrated into nurse led health checks. PCAM appeared to offer good potential to support collaborative and integrated consultations, and may increase the referral of patients to a wider range of resources. The full report of this research (including methods) can be found below.

Subsequent research studies have explored the feasibility of implementing PCAM in primary care settings with patients who have long term care needs, the incorporation of PCAM in health information exchanges to prevent hospital re-admissions with patients served in multiple care settings, and a study assessing patient complexity with hospitalized patients and their length of stay in the hospital.
