Reinforcing a continuum of care: in-hospital initiation of long-term secondary prevention following acute coronary syndromes

Nurse-led, telephone-based follow-up after acute coronary syndrome yields improved risk factors after 36 months: the randomized controlled NAILED-ACS trial

We investigated whether a nurse-led, telephone-based follow-up including medical titration was superior to usual care in improving blood pressure (BP) and low-density lipoprotein cholesterol (LDL-C) values 36 months after acute coronary syndrome (ACS). We screened all patients admitted with ACS at Östersund hospital, Sweden, between January 1, 2010, and December 31, 2014, for inclusion based on ability to participate in a telephone-based follow-up. Participants were randomly allocated to usual care or an intervention group that received counselling and medical titration to target BP < 140/< 90 mmHg and LDL-C < 2.5/< 1.8 mmol/L. The primary outcome was LDL-C at 36 months. Of 962 patients, 797 (83%) were available for analysis after 36 months. Compared to controls, the intervention group had a mean systolic BP (SBP) 4.1 mmHg lower (95% confidence interval [CI] 1.9–6.5), mean diastolic BP (DBP) 2.9 mmHg lower (95% CI 1.5–4.5), and mean LDL-C 0.28 mmol/L lower (95% CI 0.135–0.42). All P < 0.001. A significantly greater proportion of patients reached treatment targets with the intervention. After 36 months of follow-up, compared to usual care, the nurse-led, telephone-based intervention led to significantly lower SBP, DBP, and LDL-C and to a larger proportion of patients meeting target values.

Implementation of a telephone-based secondary preventive intervention after acute coronary syndrome (ACS): participation rate, reasons for non-participation and 1-year survival

Background

Acute coronary syndrome (ACS) is a major cause of death from a non-communicable disease. Secondary prevention is effective for reducing morbidity and mortality, but evidence-based targets are seldom reached and new interventional methods are needed. The present study is a feasibility study of a telephone-based secondary preventive programme in an unselected ACS cohort.

Methods

The NAILED (Nurse-based Age-independent Intervention to Limit Evolution of Disease) ACS trial is a prospective randomized controlled trial. All eligible patients admitted for ACS were randomized to usual follow-up by a general practitioner or telephone follow-up by study nurses. The intervention was made by continuous telephone contact, with counseling on healthy living and titration of medicines to reach target values for blood pressure and blood lipids. Exclusion criteria were limited to physical inability to follow the study design or participation in another study.

Results

A total of 907 patients were assessed for inclusion. Of these, 661 (72.9 %) were included and randomized, 100 (11 %) declined participation, and 146 (16.1 %) were excluded. The main reasons for exclusion were participation in another trial, dementia, and advanced disease. “Excluded” and “declining” patients were significantly older with more co-morbidity, decreased functional status, and had more seldom received education above compulsory school level than “included” patients. Non-participants had a higher 1-year mortality than participants.

Conclusions

Nurse-led telephone-based follow-up after ACS can be applied to a large proportion in an unselected clinical setting. Reasons for non-participation, which were associated with increased mortality, include older age, multiple co-morbidities, decreased functional status and low level of education.

Adherence to evidence-based secondary prevention pharmacotherapy in patients after an acute coronary syndrome: A systematic review

OBJECTIVE

To synthesize current evidence on medication adherence rates and associated risk factors in patients after an acute coronary syndrome (ACS).

METHODS

A systematic review was conducted. Five electronic databases and article bibliographies were searched for publications from 1990 to 2013 which assessed adherence to secondary prevention pharmacotherapy in adults after hospital discharge for an ACS. Identified studies were screened using pre-defined criteria for eligibility. A standardized form was used for data abstraction. Methodological quality was assessed using modified criteria for quantitative studies.

RESULTS

Sixteen studies met our inclusion criteria. Post-discharge medication adherence rates at 1-year ranged between 54% and 86%. There were no consistent predictors of non-adherence across all cardiac medication classes examined.

CONCLUSIONS

Adherence to secondary prevention pharmacotherapy was suboptimal in patients after hospital discharge for an ACS. Risk factors associated with non-adherence were examined in a limited number of studies, and the associations varied between these investigations.

Coronary Artery RIsk MAnagement Programme (CARIMAP) delivered by a rehabilitation day-hospital: impact on patients with coronary artery disease

PURPOSE

Previous studies have shown that correct management of different coronary risk factors can reduce coronary event rates. However, significant undertreatment of hyperlipidemia, diabetes, and hypertension is still found during clinical practice. The purpose of this study was to evaluate the effectiveness of an individualized management program to modify coronary disease risk profile.

METHODS

One hundred sixty-eight patients discharged from a cardiac rehabilitation department after acute coronary events were prospectively randomized into 2 management strategies: 84 started usual community care and 84 entered a Coronary Artery RIsk MAnagement Programme (CARIMAP) delivered by the rehabilitation day-hospital. Coronary risk profile, optimized therapy, and management were evaluated after the acute event and again after a followup of 9 ± 4 months in both groups.

RESULTS

Patients accessed the day-hospital an average of 4 ± 1 months (range, 1-13 months) after the acute event. The duration of the CARIMAP was 5 ± 2 months and the individual number of accesses to the day-hospital was 4 ± 3.8. After the CARIMAP, patients received better-optimized therapy (β-blockers 57% vs 85%, P < .0001; angiotensin-converting enzyme inhibitors 54% vs 84%, P < .00001; statins 38% vs 78%, P < .0001; and amlodipine 22% vs 51%, P < .0001) and had a better risk profile (low-density lipoprotein-cholesterol < 100 mg/dL 30% vs 42%, P < .0001; blood pressure < 140/90 mmHg 63% vs 88%, P < .00001).

CONCLUSION

The CARIMAP of secondary prevention delivered by a rehabilitation day-hospital to patients who had undergone an acute coronary event, enabled individually titrated therapy and better control of coronary artery risk factors.

Regular primary care plays a significant role in secondary prevention of ischemic heart disease in a Western Australian cohort

BACKGROUND

Secondary prevention for established ischaemic heart disease (IHD) involves medication therapy and a healthier lifestyle, but adherence is suboptimal. Simply having scheduled regular appointments with a primary care physician could confer a benefit for IHD patients possibly through increased motivation and awareness, but this has not previously been investigated in the literature.

OBJECTIVE

To estimate the association between regular general practitioner (GP) visitation and rates of all-cause death, IHD death or repeat hospitalisation for IHD in older patients in Western Australia (WA).

DESIGN

A retrospective cohort design.

PARTICIPANTS

Patients aged  ≥  65 years (n  = 31,841) with a history of hospitalisation for IHD from 1992-2006 were ascertained through routine health data collected on the entire WA population and included in the analysis.

MAIN MEASURES

Frequency and regularity of GP visits was determined during a three-year exposure period at commencement of follow-up. A regularity score (range 0-1) measured the regularity of intervals between the GP visits and was divided into quartiles. Patients were then followed for a maximum of 11.5 years for outcome determination. Hazard ratios and 95% confidence intervals were calculated using Cox proportional hazards models.

KEY RESULTS

Compared with the least regular quartile, patients with greater GP visit regularity had significantly decreased risks of all-cause death (2(nd) least, 2(nd) most and most regular: HR = 0.76, 0.71 and 0.71); and IHD death (2(nd) least, 2(nd) most and most regular: HR = 0.70, 0.68 and 0.65). Patients in the 2(nd) least regular quartile also appeared to experience decreased risk of any repeat IHD hospitalisation (HR =  0.83, 95%CI 0.71-0.96) as well as emergency hospitalisation (HR = 0.81, 95%CI 0.67-0.98), compared with the least regular quartile.

CONCLUSIONS

Some degree of regular GP visitation offers a small but significant protection against morbidity and mortality in older people with established IHD. The findings indicate the importance of scheduled, regular GP visits for the secondary prevention of IHD.

Transitioning the patient with acute coronary syndrome from inpatient to primary care

Patients with acute coronary syndrome (ACS) undergo several transitions in care throughout the hospital stay, from prehospitalization to the postdischarge period when patients return to primary care. Hospitalist core competencies promote safe transitions in care for patients with ACS, including hospital discharge. These competencies also highlight the central role of the hospitalist in facilitating the continuity of care and as a key link between the patient and the primary care provider (PCP). Core competencies address key decision points and processes that occur during hospitalization for ACS including the initial evaluation and risk stratification, medication reconciliation, and discharge planning. Discharge is a crucial transition and one where hospitalists can both facilitate the transition to primary care and improve adherence to quality measures established for ACS. Poor communication during discharge reportedly results in postdischarge adverse events, most often related to medications and lack of follow-up related to pending test results. Standards for a safe discharge such as Project RED (Re-Engineered Discharge), initiatives to improve outcomes after discharge like Project BOOST (Better Outcomes for Older Adults Through Safe Transitions), and adaptive tools including the ACS Transitions Tool support timely and accurate communication of complex information between the hospitalist, the PCP, and the patient. While the role of hospitalists is evolving, it is clear that they have a central role in ensuring safe transitions in care for ACS.

Appropriate secondary prevention of acute atherothrombotic events and strategies to improve guideline adherence

The use of guideline-recommended secondary prevention measures is essential for reducing the risk of subsequent events and mortality in patients who have survived an acute atherothrombotic event or have peripheral arterial disease. Although initial hospitalization provides an ideal environment to initiate such therapies, implementation of effective longterm prevention strategies is hindered by the absence of a systematic approach. In general, evidence-based clinical practice guidelines recommend antiplatelet therapy as a cornerstone of post-discharge secondary prevention, in addition to preventive measures targeting risk factors such as hypertension, dyslipidemia, cigarette smoking, and physical inactivity. Observational data indicate that, although there has been improvement over time, current utilization of guideline-recommended post-discharge treatment remains suboptimal. Recognizing the importance of a systematic approach to discharge planning, numerous hospital-based initiatives have been established. In conjunction with effective lines of communication between hospital and primary care teams, initiation of the most effective secondary prevention strategy at the time of hospital discharge will help to ensure optimal long-term management of patients after an atherothrombotic event.
