Medications and medical allergies The medical record may contain a summary of the patient's current and previous medications as well as any medical allergies. Family history The family history lists the health status of immediate family members as well as their causes of death (if known). It may also list diseases common in the family or found only in one sex or the other. It may also include a pedigree chart. It is a valuable asset in predicting some outcomes for the patient. Social history The social history is a chronicle of human interactions. It tells of the relationships of the patient, his/her careers and trainings, and religious training. It is helpful for the physician to know what sorts of community support the patient might expect during a major illness. It may explain the behavior of the patient in relation to illness or loss. It may also give clues as to the cause of an illness (e.g. occupational exposure to asbestos). Habits Various habits which impact health, such as tobacco use, alcohol intake, exercise, and diet are chronicled, often as part of the social history. This section may also include more intimate details such as sexual habits and sexual orientation. Immunization history The history of vaccination is included. Any blood tests proving immunity will also be included in this section. Growth chart and developmental history For children and teenagers, charts documenting growth as it compares to other children of the same age is included, so that health-care providers can follow the child's growth over time. Many diseases and social stresses can affect growth, and longitudinal charting can thus provide a clue to underlying illness. Additionally, a child's behavior (such as timing of talking, walking, etc.) as it compares to other children of the same age is documented within the medical record for much the same reasons as growth. Medical encounters Within the medical record, individual medical encounters are marked by discrete summations of a patient's medical history by a physician, nurse practitioner, or physician assistant and can take several forms. Hospital admission documentation (i.e., when a patient requires hospitalization) or consultation by a specialist often take an exhaustive form, detailing the entirety of prior health and health care. Routine visits by a provider familiar to the patient, however, may take a shorter form such as the problem-oriented medical record (POMR), which includes a problem list of diagnoses or a "SOAP"
