Racial Disparities in Blood Pressure Control and Treatment Differences in a Medicaid Population, North Carolina, 2005-2006
Introduction: Racial disparities in prevalence and control of high blood pressure are well-documented. We studied blood pressure control and interventions received during the course of a year in a sample of black and white Medicaid recipients with high blood pressure and examined patient, provider, and treatment characteristics as potential explanatory factors for racial disparities in blood pressure control. Methods: We retrospectively reviewed the charts of 2,078 black and 1,436 white North Carolina Medicaid recipients who had high blood pressure managed in primary care practices from July 2005 through June 2006. Documented provider responses to high blood pressure during office visits during the prior year were reviewed. Results: Blacks were less likely than whites to have blood pressure at goal (43.6% compared with 50.9%, P = .001). Blacks above goal were more likely than whites above goal to have been prescribed 4 or more antihypertensive drug classes (24.7% compared with 13.4%, P < .001); to have had medication adjusted during the prior year (46.7% compared with 40.4%, P = .02); and to have a documented provider response to high blood pressure during office visits (35.7% compared with 30.0% of visits, P = .02). Many blacks (28.0%) and whites (34.3%) with blood pressure above goal had fewer than 2 antihypertensive drug classes prescribed. Conclusion: In this population with Medicaid coverage and access to primary care, blacks were less likely than whites to have their blood pressure controlled. Blacks received more frequent intervention and had greater use of combination antihypertensive therapy. Care patterns observed in the usual management of high blood pressure were not sufficient to achieve treatment goals or eliminate disparities
Level of blood pressure above goal and clinical inertia in a Medicaid population
Failure to adjust hypertension therapy despite elevated blood pressure (BP) levels is an important contributor to lack of BP control. One possible explanation is that small elevations above goal BP are not concerning to clinicians. BP levels farther above goal, however, should be more likely to prompt clinical action. We reviewed one year’s worth of primary care records of 3,742 North Carolina Medicaid recipients 21 years and older with hypertension (a total of 15,516 office visits) to examine variations in hypertension management stratified by level of BP above goal and the association of BP level above goal with documented anti-hypertensive medication change. Among the 53% of patients not at goal BP, 42% were within 10/5 mm Hg of goal; 11% had a BP ≥40/20 mm Hg above goal. Higher level of BP above goal was independently associated with anti-hypertensive medication change. Compared to visits at which BP was <10/5 mm Hg above goal, the adjusted odds of medication change were 7.9 (95% CI 6.2-10.2) times greater at visits when patients’ BP was ≥ 40/20 mm Hg above goal. However, even when BP was above goal at this level, treatment change occurred only 46% (95% CI 40.2-51.8) of the time
Prevention and Treatment of Childhood Obesity: Care Received by a State Medicaid Population
Based on chart review for a representative cluster sample of North Carolina Medicaid enrollees aged 3 to 5 years (n = 1951) and 13 to 16 years (n = 1922) years, this study describes prevalence, practice patterns, and comorbidities related to overweight/obese immediately prior to 2007 Expert Recommendations. In total, 16% of children in both age groups were overweight, and 20% (ages 3–5 years) and 25% (ages 13–16 years) were obese. For 3- to 5-year-olds, body mass index percentile was infrequently recorded (22%) or plotted on growth charts (24%), and weight status category was rarely documented (10%). Results were similar for adolescents (21%, 20%, and 12%, respectively). In both groups, documentation of counseling in nutrition or physical activity was rare (16% for ages 3–5 years; 7% for ages 13–16 years). In adolescents, approximately 20% received recommended laboratory screening and overweight/obesity was significantly associated with chart-documented asthma, back pain, prediabetes, gastroesophageal reflux disease, hypertension, and sleep apnea. Whether improvements in documentation of care followed these new guidelines deserves further research
