NOVEL TARGETED HEALTH PSYCHOLOGY CLINIC REFERRAL IMPROVES BLOOD PRESSURE: PRELIMINARY RESULTS OF A RETROSPECTIVE STUDY

Abstract

Objective: Despite hypertension medications being widely available, many patients do not have adequately controlled blood pressure. Consequently, alternative interventions are required to support patients. Recently, we have established a novel health psychology clinic to provide additional support to help patients improve blood pressure control. This retrospective study compared outcomes before and after referral to a targeted health psychology clinic. Our aim was to determine the effectiveness of this novel clinic on patient outcomes with a view to improving the service and support rollout in other departments. Design and method: Patient notes referred to the Health Psychology clinic were reviewed from October 2020 to December 2022 (audit number: 11703). Patient data was linked anonymised and details reflecting key outcomes, demographics and specific psychology interventions were extracted. Results: In the preliminary findings, 11 patients were included for analysis. Patient age ranged from 28-79 years, 18% were female and 45% were White. Patients were prescribed a mean of 3.1 hypertension medications. The mean time between the first blood pressure reading and final reading was 44.1±27.8 weeks, with a mean number of 6.6±6 visits to the clinic. Interventions were tailored to each patient's need. Four patients were supported with anxiety management, three used biofeedback and three used breathing techniques. Two patients were supported with weight management, with one patient losing 31.7kg in 6 months. The mean systolic blood pressure (SBP) change was -11.55±17.78 mmHg (P = 0.0568), and diastolic blood pressure (DBP) was -5.80±13.15 mmHg (P = 0.1965). Two patients had increased blood pressure for unknown reasons. When these two cases were removed from analysis, the overall mean changes for SBP were -18.11±11.30 mmHg (P = 0.0013) and -9.88± 11.03mmHg for DBP (P = 0.0690). Of these blood pressure readings, 7 were conducted in the office, 2 at home, and 1 with 24hour ABPM. Conclusions: Our preliminary findings show that targeted psychological support for hypertensive patients experiencing difficulties with anxiety or depression may improve blood pressure. Health psychology interventions may be suitable to support patients where medication alone does not support optimum hypertension management. Further large prospective studies are needed to confirm these findings.
