Hospitalization is associated with a change in pharmacotherapy, which often includes antihypertensive medications, although blood pressure is often not the cause of hospitalization. The aim of this study is to investigate the changes and possible simplifications of antihypertensive pharmacotherapy in medical patients at and after discharge from the University Clinic Golnik.
The observational study included adult patients who had been prescribed antihypertensive medications before hospital admission or at discharge. Comprehensive medication history was obtained by interviewing patients, discharge therapy was obtained from the hospital medical records, and information on medication therapy 30 days after discharge was obtained by interviewing patients by telephone.
Antihypertensive drugs were taken by 76% of admitted patients (299/394), who used a median of two medications. In most cases, the antihypertensives prescribed were angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, beta blockers, calcium channel blockers and thiazides or thiazide-like diuretics. A total of 62% of patients (184/299) had their antihypertensives changed at discharge, with an average of 1,5 changes per patient. The proposed changes resulted in a change in blood pressure of at least 5 mmHg and 10 mmHg in only 36% (107/299) and 17% (50/299) of patients, respectively. After discharge, antihypertensive pharmacotherapy was changed in 37% of patients (88/239), and the vast majority of patients (9 of 10) already had changes at discharge, with proposed changes often opposite to those at discharge (53%, 67/126). Dizziness and vertigo were reported by 28% of patients (43/153) in the first month after discharge whereas 4,5% of patients (6/133) reported falls. Antihypertensive pharmacotherapy could be simplified for at least 1 in 10 patients by introducing a fixed-dose combination at discharge.
Most hospitalized patients were taking antihypertensive medications and a change in antihypertensive treatment was suggested in more than half of these patients at hospital discharge but this was not expected to result in a change in blood pressure in most patients. Interestingly, of half of the changes in antihypertensive medication suggested at discharge, an opposite change was made within 30 days of discharge, possibly due to inadequate communication with the patient and primary medical staff.
