Follow the intervals recommended by your doctor for follow‑up visits, and record every measurement in the same notebook.

Chronic conditions require trends over time, rather than a single reading. Home blood-pressure measurement alone did not clearly lower pressure in the cited analysis; greater reductions occurred when readings informed medication adjustment and support. When changing hospitals, qualifying test results marked for mutual recognition should generally be accepted without unnecessary repetition.

Each checkup costs anywhere from a few dozen to several hundred yuan. A trip to the hospital and waiting for results also takes some time. The main difficulty is that you must go regularly, which can easily be put off.

An individual-participant meta-analysis combined 7,138 participants in 15 hypertension randomized trials. At 12 months, home monitoring was associated with a clinic systolic-pressure difference of -3.2 mmHg (95% CI -4.9 to -1.6) versus usual care. Monitoring alone had no clear effect: -1.0 mmHg (-3.3 to 1.2). With the most intensive support the reduction was 6.1 mmHg (3.2 to 9.0). Support included clinician-, pharmacist- or patient-led medication adjustment, education and lifestyle guidance. These were blood-pressure outcomes, not mortality. China's hospital-test mutual-recognition rules prohibit repeating existing results that meet recognition conditions and clinical needs; qualifying reports carry an HR recognition mark, such as nationwide HR.

The author assigns B because the direct evidence concerns hypertension and blood pressure, not mortality across chronic diseases. No health-outcome study of keeping one notebook itself was found. Record at least the date, value, medicines and doses; photographs of reports are useful if kept together. Mutual recognition has exceptions, including a changed condition, rapidly changing results, surgery or transfusion preparation and emergencies. See section 24, item 5 for retaining records and images.
