Improved hypertension control using a surveillance system in a neighborhood health center
Insights
A simple hypertension surveillance system improved patient blood pressure control by 50% in two years. This cost-effective McBee card method is easily adaptable for ambulatory care settings.
Area of Science:
- Public Health
- Health Management
- Cardiovascular Disease Management
Background:
- Hypertension management requires effective patient tracking systems.
- The Dr. Martin Luther King, Jr., Health Center serves approximately 2,000 patients with hypertension.
- Existing systems may lack simplicity or cost-effectiveness.
Purpose of the Study:
- To evaluate a simple, inexpensive McBee Card Surveillance System for hypertension management.
- To assess the system's impact on patient blood pressure control rates.
- To determine the system's applicability in ambulatory care settings.
Main Methods:
- Implementation of a McBee Card Surveillance System across three health teams.
- Quarterly reporting on patient blood pressure control (defined by age-specific thresholds).
- Identification of patients due for follow-up (not seen in 4 months).
Main Results:
- A 50% increase in the percentage of hypertensive patients with controlled blood pressure over two years.
- Controlled blood pressure increased from 411 to 617 out of 929 patients.
- The system facilitated proactive patient follow-up.
Conclusions:
- The McBee Card Surveillance System is a simple, inexpensive, and effective tool for hypertension management.
- The system significantly improved blood pressure control rates in an ambulatory care setting.
- This surveillance model is readily applicable to diverse healthcare environments.
Abstract:
The Dr. Martin Luther King, Jr., Health Center has developed a simple inexpensive McBee Card Surveillance System for following approximately 2,000 registered patients with hypertension. The system has been in use for the past two years by three health teams. On a quarterly basis teams and physicians are given reports on the percentage of their hypertensive patients with controlled blood pressure (bp) (bp less than or equal to 140/90 for patients younger than 50; bp less than or equal to 160/95 for 50 or older). In addition, patients not seen in the past 4 months are identified for follow-up by family health workers. During the 2-year period that the system has been in operation, the three teams have increased their percentage of patients under control by 50%. Of 929 patients with hypertension, 411 were controlled at the inception of the study and 617 were controlled 2 years later. Such a simple surveillance and self-evaluaton system is readily applicable to all ambulatory care settings.
