Chapter 4: The Complete Health History

The Complete Health History outlines the standard adult interviewing sequence, beginning with the collection of biographic data, verifying informant reliability, and documenting the patient's primary reason for seeking care by correctly distinguishing between subjective symptoms and objective signs. Clinicians are instructed on how to thoroughly investigate the history of present illness utilizing the eight critical characteristics and the PQRSTU mnemonic, ensuring a precise evaluation of symptom provocation, quality, anatomical region, severity, timing, and the patient's personal understanding of the illness. The text highlights the critical nature of past medical history, emphasizing medication reconciliation, obstetric history, and immunization tracking, while incorporating modern genomic risk factors through the clinical use of multigenerational pedigrees or genograms and evaluating the limitations of direct-to-consumer DNA testing. A structured, head-to-toe review of systems is detailed to strictly capture the subjective health status and preventative health promotion behaviors associated with each major body system. Additionally, the chapter explores functional assessments and activities of daily living to contextualize the patient's lifestyle, employing specific screening instruments such as the CAGE questionnaire for substance abuse and the FICA tool for spiritual resources, alongside evaluations for intimate partner violence and occupational environmental hazards. Finally, the text adapts these fundamental assessment techniques for developmental competence across the lifespan, addressing specialized pediatric requirements like prenatal histories, immunizations strategies, and developmental milestones, as well as introducing the targeted HEEADSSS psychosocial interview framework to effectively screen adolescents for high-risk behaviors encompassing mental health, substance use, and sexuality.
