Person-Centered Models for Cardiovascular Care: A Review of the Evidence: A Scientific Statement From the American Heart Association

Cardiovascular disease remains the leading cause of death and disability in the United States and globally. Disease burden continues to escalate despite technological advances associated with improved life expectancy and quality of life. As a result, longer life is associated with multiple chronic cardiovascular conditions. Clinical guidelines provide recommendations without considering prevalent scenarios of multimorbidity and health system complexities that affect practical adoption. The diversity of personal preferences, cultures, and lifestyles that make up one's social and environmental context is often overlooked in ongoing care planning for symptom management and health behavior support, hindering adoption and compromising patient outcomes, particularly in groups at high risk. The purpose of this scientific statement was to describe the characteristics and reported outcomes in existing person-centered care delivery models for selected cardiovascular conditions. We conducted a scoping review using Ovid MEDLINE, Embase.com, Web of Science, CINAHL Complete, Cochrane Central Register of Controlled Trials through Ovid, and ClinicalTrials.gov from 2010 to 2022. A range of study designs with a defined aim to systematically evaluate care delivery models for selected cardiovascular conditions were included. Models were selected on the basis of their stated use of evidence-based guidelines, clinical decision support tools, systematic evaluation processes, and inclusion of the patient's perspective in defining the plan of care. Findings reflected variation in methodological approach, outcome measures, and care processes used across models. Evidence to support optimal care delivery models remains limited by inconsistencies in approach, variation in reimbursement, and inability of health systems to meet the needs of patients with chronic, complex cardiovascular conditions.

Pharmacist Interventions for Medication Adherence: Community Guide Economic Reviews for Cardiovascular Disease

INTRODUCTION

Adherence to medications for cardiovascular disease and its risk factors is less than optimal, although greater adherence to medication has been shown to reduce the risk factors for cardiovascular disease. This paper examines the economics of tailored pharmacy interventions to improve medication adherence for cardiovascular disease prevention and management.

METHODS

Literature from inception of databases to May 2019 was searched, yielding 29 studies for cardiovascular disease prevention and 9 studies for cardiovascular disease management. Analyses were done from June 2019 through May 2020. All monetary values are in 2019 U.S. dollars.

RESULTS

The median intervention cost per patient per year was $246 for cardiovascular disease prevention and $292 for cardiovascular disease management. The median change in healthcare cost per person per year due to the intervention was -$355 for cardiovascular disease prevention and -$2,430 for cardiovascular disease management. The median total cost per person per year was -$89 for cardiovascular disease prevention, with a median return on investment of 0.01. The median total cost per person per year for cardiovascular disease management was -$1,080, with a median return on investment of 7.52, and 6 of 7 estimates indicating reduced healthcare cost averted exceeded intervention cost. For cardiovascular disease prevention, the median cost per quality-adjusted life year gained was $11,298. There were no cost effectiveness studies for cardiovascular disease management.

DISCUSSION

The evidence shows that tailored pharmacy-based interventions to improve medication adherence are cost effective for cardiovascular disease prevention. For cardiovascular disease management, healthcare cost averted exceeds the cost of implementation for a favorable return on investment from a healthcare systems perspective.

Using pharmacy technicians and electronic health record capabilities to improve outcomes for patients with cardiovascular disease

OBJECTIVE

This study aimed to compare lipid and blood pressure (BP) control before and after implementing a certified pharmacy technician (CPhT) protocol that optimized electronic health record (EHR) capabilities and shifted work from clinical pharmacy specialists (CPSs) to CPhT.

SETTING

Kaiser Permanente Colorado's pharmacist-managed cardiac risk reduction service (which manages dyslipidemia, hypertension, and diabetes for all patients with atherosclerotic cardiovascular disease).

PRACTICE DESCRIPTION

In 2019, a protocol that optimized EHR capabilities and allowed work to be offloaded from CPS to CPhT was implemented. Filtered views within the EHR were created that bucketed patients with specific lipid results criteria. The CPhT protocol provided guidance to CPhT on determining whether patients were at low-density lipoprotein cholesterol (LDL-C) and non-high-density lipoprotein (non-HDL) goals, on appropriate statin intensity, adherent to medications, and whether the most recent BP was controlled. The CPhT notified CPS of uncontrolled patients who would assess and manage these patients, as necessary. The CPhT notified controlled patients of their results.

PRACTICE INNOVATION

Data on the outcomes of incorporating pharmacy technicians to support CPS clinical activities in ambulatory clinical pharmacy are limited.

EVALUATION METHODS

This retrospective study compared a "Pharmacist-Driven" (index date: January 1, 2016) with a "Tech-Enhanced" (index date: January 1, 2019) group. The primary outcome was the proportion of patients at all goals defined as LDL-C < 70 mg/dL, non-HDL < 100 mg/dL, and BP < 140/90 mm Hg at 1 year after the index dates.

RESULTS

There were 6813 patients included (mean age: 70.2 ± 11.1 years, 71.4% male): 3130 and 3683 in the "Pharmacist-Driven" and "Tech-Enhanced" groups, respectively. The proportion of patients who attained LDL-C, non-HDL, and BP goals was higher in the "Tech-Enhanced" group (51.1% vs. 39.7%, P < 0.001) than the "Pharmacist-Driven" group.

CONCLUSION

A protocol integrating EHR decision support and CPhTs enabled work to shift to from CPS to CPhT and improved clinical outcomes.

Coronary Artery Disease in Patients Older than 35 and Eligible for Cardiovascular Secondary Prevention: An Italian Retrospective Observational Analysis of Healthcare Administrative Databases

Background: This study describes patients with coronary artery disease (CAD) who are eligible for secondary prevention and assesses their healthcare consumption and costs from the perspective of the Italian National Health Service (INHS). Methods: From the Fondazione Ricerca e Salute’s database, which collects Italian healthcare administrative data, all patients aged ≥ 35, with ≥1 primary in-hospital CAD diagnosis and/or procedure on the coronary arteries, or with the specific disease exemption code, and who are suitable for long-term secondary prevention treatments, were identified in 2018 and analyzed. Demographics, comorbidities, one-year supplied drugs, hospitalizations, and costs were analyzed. Results: From >3 million inhabitants aged ≥ 35, 46,063 (1.3%) were identified (72.1% males, mean age 70 ± 12; approximately 50% with ≥3 comorbidities). During a one-year follow-up, 96.4% were treated with ≥1 drug for secondary prevention (mainly antiplatelets and lipid lowering agents), 69.4% with ≥1 concomitant cardiovascular drug, and 95.8% with ≥1 concomitant non-cardiovascular therapy. Within one year, 30.6% of patients were hospitalized at least once, mostly due to non-cardiovascular events. Calculated by mean, the INHS paid EUR 6078 per patient. Conclusions: This analysis confirms the relevant burden of CAD for patients with many comorbidities and who are frequently hospitalized, and the burden on the INHS. A multidisciplinary healthcare approach is encouraged to improve patients’ outcomes and reduce costs for the INHS.

Innovative Managed Care May Be Related to Improved Prognosis for Acute Myocardial Infarction Survivors

BACKGROUND

Mortality following discharge in myocardial infarction survivors remains high. Therefore, we compared outcomes in myocardial infarction survivors participating and not participating in a novel, nationwide managed care program for myocardial infarction survivors in Poland.

METHODS

We used public databases. We included all patients hospitalized due to acute myocardial infarction in Poland between October 1, 2017 and December 31, 2018. We excluded from the analysis all patients aged <18 years as well as those who died during hospitalization or within 10 days following discharge from hospital. All patients were prospectively followed. The primary end point was defined as death from any cause.

RESULTS

The mean follow-up was 324.8±140.5 days (78 034.1 patient-years; 340.0±131.7 days in those who did not die during the observation). Participation in the managed care program was related to higher odds ratio of participating in cardiac rehabilitation (4.67 [95% CI, 4.44-4.88]), consultation with a cardiologist (7.32 [6.83-7.84]), implantable cardioverter-defibrillator (1.40 [1.22-1.61]), and cardiac resynchronization therapy with cardioverter-defibrillator implantation (1.57 [1.22-2.03]) but lower odds of emergency (0.88 [0.79-0.98]) and nonemergency percutaneous coronary intervention (0.88 [0.83-0.93]) and coronary artery bypass grafting (0.82 [0.71-0.94]) during the follow-up. One-year all-cause mortality was 4.4% among the program participants and 6.0% in matched nonparticipants. The end point consisting of all-cause death, myocardial infarction, or stroke occurred in 10.6% and 12.0% (P<0.01) of participants and nonparticipants respectively, whereas all-cause death or hospitalization for cardiovascular reasons in 42.2% and 47.9% (P<0.001) among participants and nonparticipants, respectively. The difference in outcomes between patients participating and not participating in the managed care program could be explained by improved access to cardiac rehabilitation, cardiac care, and cardiac procedures.

CONCLUSIONS

Managed care following myocardial infarction may be related to improved prognosis as it may facilitate access to cardiac rehabilitation and may provide a higher standard of outpatient cardiac care.

The Role of the Clinical Pharmacist in a Preventive Cardiology Practice

Background: Cardiovascular disease (CVD) remains the leading cause of morbidity and mortality worldwide. In response, a multidisciplinary team approach, which includes clinical pharmacists, is recommended to improve patient outcomes. The purpose of the study was to describe interventions associated with integration of a clinical pharmacist, with an emphasis on pharmacist-generated patient cost avoidance. Methods: This is a prospective observational study detailing pharmacist-initiated interventions within an academic preventive cardiology service. Interventions targeting pharmacotherapy optimization, side effect management, patient education, medication adherence, and cost avoidance were implemented during shared office visits with providers and/or on provider consultation for remote follow-up. Tabulation of cost avoidance was arranged into 2 formats: clinical interventions implemented by the pharmacist and direct patient out-of-pocket expense reduction. Money saved per clinical intervention was extrapolated from data previously published. Patient out-of-pocket expense prior to and after pharmacist involvement was calculated to assess aggregate yearly patient cost savings. Results: Over 12 months the pharmacist intervened on 974 patients, totaling 3725 interventions. Cost avoidance strategies resulted in yearly savings of $830 748 in aggregate—$149 566 from clinical interventions and $681 182 from patient out-of-pocket expense reduction. Monthly patient out-of-pocket expense was reduced from a median (interquartile range) of $217 ($83.5-$347) before to $5 ($0-$18) after pharmacist intervention. Conclusions: Addition of a clinical pharmacist within an academic preventive cardiology clinic generated substantial pharmacotherapy interventions, resulting in significant cost avoidance for patients. The resulting cost avoidance may result in improved medication adherence and clinical outcomes.

Pharmacist prescribing practices in a clinical pharmacy cardiac risk service

PURPOSE

Prescribing practices within a clinical pharmacy cardiac risk service (CPCRS) and their impact on treatment outcomes in patients with atherosclerotic cardiovascular disease (ASCVD) are described.

SUMMARY

National healthcare reforms have increased the population of insured patients and placed increased demands on physicians and other providers. Pharmacists are well trained and positioned to aid in patient care by providing expertise in medication management and patient safety that can result in pharmacotherapy optimization and cost savings. Kaiser Permanente Colorado (KPCO), a group-model health maintenance organization with about 675,000 members served by 30 medical offices throughout Colorado, has adopted a collaborative drug therapy management (CDTM) model that enables pharmacist prescribing to improve patient access, patient care, and healthcare cost-effectiveness. Within the CPCRS established by KPCO, qualified pharmacists are permitted to prescribe initial therapy, modify drug regimens, order laboratory tests, and perform follow-up activities within their professional scope of practice. The CPCRS focuses on the long-term management of patients with ASCVD. The primary goals of the CPCRS are to optimize secondary-prevention pharmacotherapy, monitor and ensure medication adherence, assist in the management of risk factors for ASCVD, provide patient education and counseling, and serve as a resource for physicians and other healthcare providers. Working under a CDTM agreement, pharmacists are authorized to prescribe therapies to minimize the risk of future ASCVD events.

CONCLUSION

The CPCRS at KPCO has demonstrated successful maintenance of a clinical pharmacy service including pharmacist prescribing under a CDTM model to manage patients with ASCVD.

The excess health care costs of KardioPro, an integrated care program for coronary heart disease prevention

Coronary heart disease (CHD) is a major cause of death and important driver of health care costs. Recent German health care reforms have promoted integrated care contracts allowing statutory health insurance providers more room to organize health care provision. One provider offers KardioPro, an integrated primary care-based CHD prevention program. As insurance providers should be aware of the financial consequences when developing optional programs, this study aims to analyze the costs associated with KardioPro participation. 13,264 KardioPro participants were compared with a propensity score-matched control group. Post-enrollment health care costs were calculated based on routine data over a follow-up period of up to 4 years. For those people who incurred costs, KardioPro participation was significantly associated with increased physician costs (by 33%), reduced hospital costs (by 19%), and reduced pharmaceutical costs (by 16%). Overall costs were increased by 4%, but this was not significant. Total excess costs per observation year were €131 per person (95% confidence interval: [€-36.5; €296]). Overall, KardioPro likely affected treatment as the program increased costs of physician services and reduced costs of hospital services. Further effects of substituting potential inpatient care with increased outpatient care might become fully apparent only over a longer time horizon.

Comparative health systems research among Kaiser Permanente and other integrated delivery systems: a systematic literature review

CONTEXT

Because of rising health care costs, wide variations in quality, and increased patient complexity, the US health care system is undergoing rapid changes that include payment reform and movement toward integrated delivery systems. Well-established integrated delivery systems, such as Kaiser Permanente (KP), should work to identify the specific system-level factors that result in superior patient outcomes in response to policymakers' concerns. Comparative health systems research can provide insights into which particular aspects of the integrated delivery system result in improved care delivery.

OBJECTIVE

To provide a baseline understanding of comparative health systems research related to integrated delivery systems and KP.

DESIGN

Systematic literature review.

METHODS

We conducted a literature search on PubMed and the KP Publications Library. Studies that compared KP as a system or organization with other health care systems or across KP facilities internally were included. The literature search identified 1605 articles, of which 65 met the study inclusion criteria and were examined by 3 reviewers.

RESULTS

Most comparative health systems studies focused on intra-KP comparisons (n = 42). Fewer studies compared KP with other US (n = 15) or international (n = 12) health care systems. Several themes emerged from the literature as possible factors that may contribute to improved care delivery in integrated delivery systems.

CONCLUSIONS

Of all studies published by or about KP, only a small proportion of articles (4%) was identified as being comparative health systems research. Additional empirical studies that compare the specific factors of the integrated delivery system model with other systems of care are needed to better understand the "system-level" factors that result in improved and/or diminished care delivery.
