Monitoring blood pressure

Monitoring at home

Various types of self monitors are available on the market for the growing number of people who want to check their own blood pressure at home.

Benefits of self monitoring mentioned by patients included gaining reassurance and understanding more about how blood pressure fluctuates.

Another advantage was that monitoring allowed the patient to take responsibility for their condition and to check if stress is having effect.

One person explained how having a 24 hour monitor made it much easier to cope with their high blood pressure (hypertension), which could be very stressful precisely because it causes no symptoms. Another was encouraged by the experience of a colleague who had managed to bring his blood pressure down by using a monitor.

Monitoring could also convince the patient that their high blood pressure was real and that medication was necessary. This may be particularly important for patients who suspect that they may only have ‘white coat hypertension’ – where the blood pressure is normal away from the doctor’s surgery.

People who said that they did not want to have their own blood pressure monitor at home included those who were concerned about obsessive use, and some had been discouraged by doctors or nurses who had suggested that self monitors were unreliable. There was also a concern that the equipment is too expensive.

Monitoring at the GPs or outpatients

Blood pressure checks are common in general practice and most people remembered having theirs checked on several occasions before their hypertension was diagnosed.

When talking about their blood pressure results, some of those interviewed referred to the numerical readings (often if they had their own monitors) while others described their reading in terms of what was thought to be high or normal. Some did not know or recall their numerical readings, or preferred not to think about them between visits to the surgery or hospital.

While some people said they ask for the results when having their blood pressure taken, others ask for comment on the result or find less direct ways to ask, such as when they should come for their next appointment. Appointments varied from one week, when a new medication was being monitored, to once every six months. For those who attended hospital outpatients the check-ups were six-monthly or annual, with interim checks by the GP.

While one patient felt that the care with which his blood pressure was checked at the hospital was better than at the GPs, others thought that hospital appointments were a waste of time or suggested that once the blood pressure was settled there was little to be gained from regular check-ups. A long wait at the GPs could be frustrating. Some thought that there might be other reasons for high readings at the GPs, including white coat syndrome.
