For all persons, OBTOTVIS captures the total number of office-based medical provider visits during the year. These are encounters that took place primarily in office-based settings and clinics, and include visits to both physician (OBPHVIS) and non-physician (OBNPHVIS) providers. For a small proportion of sample persons, the sum of the physician and non-physician visit variables is less than the total number of office-based visits because OBTOTVIS contains reported visits where the respondent did not know the type of provider.
Summary variables related to the total number of office-based medical encounters are also available broken down by the type of medical provider seen, including physicians (OBPHVIS), non-physicians (OBNPHVIS), chiropractors (OBCHIVIS), nurse practitioners (OBNPVIS), optometrists (OBOPTVIS), physician assistants (OBPAVIS), and physical or occupational therapists (OBTHVIS).
OBTOTVIS is a 3-digit numeric variable.
