Veteran Preference For Group Visits and Its Effect on Hypertension Outcomes
Veteran Preference For Group Visits and Its Effect on Hypertension Outcomes
To determine racial/ethnic differences in preference for group visits in veterans with poorly
 controlled hypertension (State 2 hypertension) and determine the effect of group visits on
 health outcomes among veterans with poorly controlled hypertension.
Research Design: Randomized clinical trial to assess veterans� preference for group visits
 and the effect of group visits on hypertension outcomes. Hypertension affects close to 50
 million persons in the U.S., with prevalence, severity, and impact being increased in
 non-white Americans 1.Despite recent clinical trials associating successful antihypertensive
 therapy with reductions in stroke incidence, myocardial infarction, and heart failure,
 control rates remain below the Healthy People 2010 goal of 50%. The importance of blood
 pressure control is recognized within the VA as two of the conditions selected for QUERI
 include ischemic heart disease and congestive heart disease, and blood pressure control is a
 performance measure for every VAMC 2. Clinical trials have shown that blood pressure control
 can be achieved in most patients with hypertension 3. When physicians fail to prescribe
 lifestyle modification, adequate doses of antihypertensive medications, or appropriate drugs,
 blood pressure control may not be achieved.1 In the course of a 15-30 minute visit with a
 primary care physician, lifestyle modifications may not be addressed and inertia may prevent
 rapid adjustments in medication dosages or changes in drug combinations. 4. The outpatient
 group visit model is an intervention developed by managed care organizations to capitalize on
 economy of scale. It has significant points of departure from the existing health care
 delivery system design, which focuses on acute care. The outpatient group visit model also
 fosters a more collaborative effort between the physician and patient, introduces nurses as
 knowledgeable team members who can be trusted to communicate important information to
 patients and between patients and physicians, and promotes peer support among the
 participating patients. Group visits have proven successful in high health services utilizing
 elderly patients with one or more chronic illnesses. A one-year study of monthly 2-hour group
 visits led by a physician and nurse showed significant improvements in care delivery as
 measured by decreases in emergency room visits, specialty care visits, and hospital
 readmissions though no change in self-reported health and functional status were realized. 5.
 Also, patients with type 2 diabetes attending group visits were shown to have increases in
 quality of life measures, knowledge of type 2 diabetes, and improved metabolic control as
 compared to patients in usual care. 6. Group visits offer providers more time per visit to
 address process-of-care indicators and provide patients more time per visit with their
 primary care physician. The monthly schedule allows for more frequent contacts between the
 patients and physicians. Providers caring for patients in groups can deliver consistent
 messages to multiple patients at once. Though monthly primary care visits (in groups) would
 be an increase from the 4 primary care visits per year presently realized by veterans with
 hypertension at the Ralph H. Johnson VAMC, the frequency is more consistent with JNC 7
 guidelines for monthly visits for follow-up and monitoring after the initiation of
 antihypertensive therapy. Presently, the average primary care physician at the Charleston VA
 is scheduled to see 2 patients per hour. Group visits would allow the physician to see 20
 patients over 2 hours. While demonstrated feasible and acceptable to elderly, chronically ill
 managed care populations, and uninsured and underinsured patients with type 2 diabetes, group
 visits have not been systematically tested in the Veteran�s Health Administration system.
 Additionally, previous studies have not evaluated patients� acceptance of group visits or
 their responses to groups according to race/ethnicity. This study seeks to inform whether
 group visits are acceptable to veterans as a method of health care delivery, regardless of
 race/ethnicity.

 Methods: The study will assess the effect of group visits on hypertension outcomes. Veterans
 with stage 2 hypertension (systolic blood pressure =160 mmHg or diastolic blood pressure =100
 mmHg) will be identified during routine office visits. The primary care physician will
 explain what group visits are using a standard script then patients will be asked if they are
 willing to be seen in a group setting. Patients who indicate a willingness to receive care in
 a group setting will be randomly assigned to either group visits or usual care. Randomization
 will occur in blocks to insure equal number of subjects by race/ethnicity in each of the two
 groups (group setting vs. usual care). We will recruit up to 8 VA primary care physicians to
 participate in this study. Several have already indicated an interest in conducting group
 visits.

 Patient Visit Protocol: Group visits will be co-led by the patients� primary care internal
 medicine physician and a clinic nurse. Each group visit session will be scheduled for two
 hours consisting of: 15 minutes for "warm-up" and socialization, 30 minutes for presentation
 of a health- related topic (facilitated by the physician or another team member with special
 expertise), 15 minutes for break, during which time the nurse and physician will circulate,
 attending to individual needs, immunizations, appointment scheduling, and other issues, 15
 minutes for questions and answers, 15 minutes for planning the next session, and 30 minutes
 for one-on-one consultations with the physician. Upon conclusion of the group portion of the
 visit, patients will have the opportunity to see the physician individually if required.
 While the group visits are intended to be the main source of medical care, patients who need
 care in between scheduled group visits, or who have specific medical needs that cannot be
 accommodated in the group visit (i.e. PAP smears, DRE), will be able to schedule a one-on-one
 visit with their primary care provider.
