About this study
Aim 1 The main aim is to compare the effects of intensive BP intervention between the intervention and usual care arm on the rate of change in TICS-m per year. The investigators will recruit 4,000 patients over 70 years of age with BP \>130/80 mmHg from 2 diverse health systems and randomize patients within each health system to usual care or to a combination of care with clinical decision support, practice facilitators and Pharm Ds to lower home BP to \< 130/80 mmHg. The primary outcome of this trial will be development cognitive decline as determined by a decrease in TICS-m scores from baseline. As a secondary outcome, the investigators will also measure the development of mild cognitive impairment or dementia in a subset of patients who show a decline of ≥3 points through adjudication.
Aim 2a Determine the potential harms of intensive lowering BP. The investigators aim to recruit 4,000 study participants and compare the effects of lowering home BP below 130/80 mmHg with usual care on hospitalizations, emergency department visits, cardiovascular events, deaths, syncope, falls, fractures, hypotension, electrolyte abnormalities and acute kidney injury. The investigators will capture measures of adherence and health care resource utilization. The investigators will assess QOL in 4,000 patients. The investigators will capture possible harms of lowering BP below 130/80 mmHg. The investigators have chosen clinical outcomes of relevance to all the stakeholders based on prior experience on pragmatic clinical trials and our prior experience in ICD-Pieces. Outcomes will be captured from the telephone assessment by study personnel and electronic health records and/or claims data and reflecting possible harms from all participants will include hospitalizations, emergency department visits, cardiovascular events, deaths, syncope, hypotension, falls, fractures, electrolyte disturbances and acute kidney injury. There will also be capture of adherence by pharmacy refill data. The investigators will capture BP readings from each visit. The investigators will also capture number of encounters with the health system as a measure of health care utilization.
Aim 2b Determine the impact of intensive BP management on QOL. Determine the impact of intensive BP management on QOL. Quality of life (QOL) scores will be obtained using the PROMIS Scale v1.2 - Global Health instrument annually after the administration of the TICS-m.
