Healthcare Resources Utilization throughout the Last Year of Life after Acute Myocardial Infarction.

Healthcare resource utilization (HRU) peaks in the last year-of-life, and accounts for a substantial share of healthcare expenditure. We evaluated changes in HRU and costs throughout the last year-of-life among AMI survivors and investigated whether such changes can predict imminent mortality. This retrospective analysis included patients who survived at least one year following an AMI. Mortality and HRU data during the 10-year follow-up period were collected. Analyses were performed according to follow-up years that were classified into mortality years (one year prior to death) and survival years. Overall, 10,992 patients (44,099 patients-years) were investigated. Throughout the follow-up period, 2,885 (26.3%) patients died. The HRU parameters and total costs were strong independent predictors of mortality during a subsequent year. While a direct association between mortality and hospital services (length of in-hospital stay and emergency department visits) was observed, the association with ambulatory services utilization was reversed. The discriminative ability (c-statistics) of a multivariable model including the HRU parameters for predicting the mortality in the subsequent year, was 0.88. In conclusion, throughout the last year of life, hospital-centered HRU and costs of AMI survivors increase while utilization of ambulatory services decrease. HRUs are strong and independent predictors of an imminent mortality year among these patients.

Norton Scale Score and long-term healthcare services utilization after acute myocardial infarction.

AIMS: Many patients admitted with acute myocardial infarction (AMI) have considerable multimorbidity, sometimes associated with functional limitations. The Norton Scale Score (NSS) evaluates clinical aspects of well-being and predicts numerous clinical outcomes. We evaluated the association between NSS and long-term healthcare utilization (HU) following a non-fatal AMI. METHODS AND RESULTS: A retrospective observational study including AMI survivors during 1 January 2004 to 31 December 2015 with a filled NSS report. Data were recouped from the electronic medical records of the hospital and two Health Maintenance Organizations. Norton Scale Score ≤16 or >16 was defined as low or high respectively. The outcome was annual HU, encompassing length of hospital stay (LOS), emergency department (ED) visits, primary care, and other ambulatory service utilization during up to 10 years of follow-up. HU costs were compared between groups. Two-level models were built: unadjusted and adjusted for patients' baseline characteristics. The study included 4613 patients, 784 (17%) had low NSS. Patients with low NSS compared with patients with high NSS were older, had a higher rate of multimorbidity, and had significantly lower coronary angiography and revascularization rates. In addition, low NSS patients presented higher annual HU costs (4879 vs. 3634 Euro, P <0.001), primarily due to LOS, ED visits, and less frequent ambulatory services usage. CONCLUSION: In patients after non-fatal AMI, low NSS is a signal for higher long-term costs reflecting the presence of expensive comorbidities. Management disparity and impaired mobility may offset the real need of these patients. Therefore, the specific proactive nursing intervention in that population is recommended.

Register-based information on thyroid diseases in Europe: lessons and results from the EUthyroid collaboration.

Objective: Registers of diagnoses and treatments exist in different forms in the European countries and are potential sources to answer important research questions. Prevalence and incidence of thyroid diseases are highly dependent on iodine intake and, thus, iodine deficiency disease prevention programs. We aimed to collect European register data on thyroid outcomes to compare the rates between countries/regions with different iodine status and prevention programs. Design: Register-based cross-sectional study. Methods: National register data on thyroid diagnoses and treatments were requested from 23 European countries/regions. The provided data were critically assessed for suitability for comparison between countries/regions. Sex- and age-standardized rates were calculated. Results: Register data on ≥1 thyroid diagnoses or treatments were available from 22 countries/regions. After critical assessment, data on medication, surgery, and cancer were found suitable for comparison between 9, 10, and 13 countries/regions, respectively. Higher rates of antithyroid medication and thyroid surgery for benign disease and lower rates of thyroid hormone therapy were found for countries with iodine insufficiency before approx. 2001, and no relationship was observed with recent iodine intake or prevention programs. Conclusions: The collation of register data on thyroid outcomes from European countries is impeded by a high degree of heterogeneity in the availability and quality of data between countries. Nevertheless, a relationship between historic iodine intake and rates of treatments for hyper- and hypothyroid disorders is indicated. This study illustrates both the challenges and the potential for the application of register data of thyroid outcomes across Europe.

Associations between Subsequent Hospitalizations and Primary Ambulatory Services Utilization within the First Year after Acute Myocardial Infarction and Long-Term Mortality.

Healthcare resource utilization peaks throughout the first year following acute myocardial infarction (AMI). Data linking the former and outcomes are sparse. We evaluated the associations between subsequent length of in-hospital stay (SLOS) and primary ambulatory visits (PAV) within the first year after AMI and long-term mortality. This retrospective analysis included patients who were discharged following an AMI. Study groups: low (0-1 days), intermediate (2-7) and high (≥8 days) SLOS; low (<10) and high (≥10 visits) PAV, throughout the first post-AMI year. All-cause mortality was set as the primary outcome. Overall, 8112 patients were included: 55.2%, 23.4% and 21.4% in low, intermediate and high SLOS groups respectively; 26.0% and 74.0% in low and high-PAV groups. Throughout the follow-up period (up to 18 years), 49.6% patients died. Multivariable analysis showed that an increased SLOS (Hazard ratio (HR) = 1.313 and HR = 1.714 for intermediate and high vs. low groups respectively) and a reduced number of PAV (HR = 1.24 for low vs. high groups) were independently associated with an increased risk for mortality (p < 0.001 for each). Long-term mortality following AMI is associated with high hospital and low primary ambulatory services utilization throughout the first-year post-discharge. Measures focusing on patients with increased SLOS and reduced PAV should be considered to improve patient outcomes.

Mortality and healthcare resource utilization following acute myocardial infarction according to adherence to recommended medical therapy guidelines.

Guideline recommended medical therapy (GRMT) plays a pivotal role in improving long-term outcomes and healthcare burden of acute myocardial infarction (AMI) patients. We evaluated patients' adherence to GRMT following AMI and the association with long-term (up-to 10 years) mortality, healthcare resource utilization and costs. METHODS: AMI patients hospitalized in a tertiary medical center in Israel that survived at least a year following post-discharge and enrolled in the two largest health plans were analyzed. Data were obtained from computerized medical records. Patients were defined as adherent when ≥80 % of the GRMT prescriptions were issue during the first post-discharge year. Hospitalizations, emergency department (ED) visits, primary care utilization and outpatient consulting clinic and other ambulatory services expenditure were calculated annually. RESULTS: Overall 8287 patients qualified for the study (mean age 65.0 ± 13.6 years, 69.7 % males). Adherent patients (n = 1767, 21.3 %) were more likely to be younger, women and increased prevalence of most traditional cardiovascular risk factors. Throughout the follow-up, 2620 patients (31.6 %) died, 22.0 % versus 34.2 %, in the adherent vs. the non-adherent group (adjHR = 0.816, 95 % CI:0.730-0.913, p < 0.001). Reduced hospitalizations (adjOR = 0.783, p < 0.001), ED visits (adjOR = 0.895, p = 0.033), and costs (adjOR = 0.744, p < 0.001), yet increased primary clinics (adjOR = 2.173, p < 0.001) ambulatory (adjOR = 1.072, p = 0.018) and consultant (adjOR = 1.162, p < 0.001) visits, were observed. CONCLUSIONS: Adherence to GRMT following AMI is associated with decreased mortality, hospitalizations and costs.

Sex and Ethnic Disparities in Health-Related Outcomes Following Acute Myocardial Infarction in Israel.

BACKGROUND: Survivors of acute myocardial infarction (AMI) are at increased risk for recurrent cardiac events and tend to use excessive healthcare services, thus resulting in increased costs. OBJECTIVES: To evaluate the disparities in healthcare resource utilization and costs throughout a decade following a non-fatal AMI according to sex and ethnicity groups in Israel. METHODS: A retrospective study included AMI patients hospitalized at Soroka University Medical Center during 2002-2012. Data were obtained from electronic medical records. Post-AMI annual length of hospital stay (LOS); number of visits to the emergency department (ED), primary care facilities, and outpatient consulting clinics; and costs were evaluated and compared according sex and ethnicity groups. RESULTS: A total of 7685 patients (mean age 65.3 ± 13.6 years) were analyzed: 56.8% Jewish males (JM), 26.6% Jewish females (JF), 12.4% Bedouin males (BM), and 4.2% Bedouin females (BF). During the up-to 10-years follow-up (median 5.8 years), adjusted odds ratios [AdjOR] for utilizations of hospital-associated services were highest among BF (1.628 for LOS; 1.629 for ED visits), whereas AdjOR for utilization of community services was lowest in BF (0.722 for primary clinic, 0.782 for ambulatory, and 0.827 for consultant visits), compared with JM. The total cost of BF was highest among the study groups (AdjOR = 1.589, P < 0.01). CONCLUSIONS: Long-term use of hospital-associated healthcare services and total costs were higher among Bedouins (especially BF), whereas utilization of ambulatory services was lower in these groups. Culturally and economically sensitive programs optimizing healthcare resources utilization and costs is warranted.

Temporal trends in healthcare resource utilization and costs following acute myocardial infarction.

BACKGROUND: Acute myocardial infarction (AMI) is associated with greater utilization of healthcare resources and financial expenditure. OBJECTIVES: To evaluate temporal trends in healthcare resource utilization and costs following AMI throughout 2003-2015. METHODS: AMI patients who survived the first year following hospitalization in a tertiary medical center (Soroka University Medical Center) throughout 2002-2012 were included and followed until 2015. Length of the in-hospital stay (LOS), emergency department (ED), primary care, outpatient consulting clinic visits and other ambulatory services, and their costs, were evaluated and compared annually over time. RESULTS: Overall 8047 patients qualified for the current study; mean age 65.0 (SD = 13.6) years, 30.3% women. During follow-up, LOS and the number of primary care visits has decreased significantly. However, ED and consultant visits as well as ambulatory-services utilization has increased. Total costs have decreased throughout this period. Multivariate analysis, adjusted for potential confounders, showed as significant trend of decrease in LOS and ambulatory-services utilization, yet an increase in ED visits with no change in total costs. CONCLUSIONS: Despite a decline in utilization of most healthcare services throughout the investigated decade, healthcare expenditure has not changed. Further evaluation of the cost-effectiveness of long-term resource allocation following AMI is warranted. Nevertheless, we believe more intense ambulatory follow-up focusing on secondary prevention and early detection, as well as high-quality outpatient chest pain unit are warranted.

Healthcare-service utilization and direct costs throughout ten years following acute myocardial infarction: Soroka Acute Myocardial Infarction II (SAMI II) project.

Objective: Acute myocardial infarction (AMI) is associated with significant risk for long-term morbidity and healthcare expenditure. We investigated healthcare utilization and direct costs throughout 10 years following AMI. Methods: A retrospective study included AMI patients hospitalized in a tertiary medical center throughout 2002-2012. Data was obtained from computerized medical records. Hospitalizations, emergency department (ED), primary care and outpatient consulting clinic visits and other ambulatory services, following the AMI and their costs, were compared with the year preceding the AMI. Results: Overall 9548 patients were analyzed (age 66.6 ± 13.9 years, 67.8% men, 48.1% ST-elevation AMI). A significant increase in the utilization of all the evaluated services was observed in the first year following the AMI compared with the preceding year (p < .001 for each) and followed by a decline thereafter (p-for trend < .001 for each) except increased number of ED visits (p-for trend = .014). Annual per-patient costs throughout the first year following AMI (5592€) were significantly greater compared with the preceding year (3120€) and declined subsequently to 3216€ and 2760€ for years 2-5 and 6-10, respectively. Multivariate analysis showed that throughout the first half of the follow-up total costs were slightly higher and in the second half similar to the year preceding the AMI. Analysis of the relative costs showed that ambulatory services make up most of the expenditure. Conclusions: Healthcare utilization and economic expenditure peak throughout the first year and decline afterwards. For several services it remains higher for up to 10 years compared with the year preceding the AMI.

Statin Therapy: Diabetes Mellitus Risk and Cardiovascular Benefit in Primary Prevention.

BACKGROUND: The salutary effects of statin therapy in patients with cardiovascular disease (CVD) are well established. Although generally considered safe, statin therapy has been reported to contribute to induction of diabetes mellitus (DM). OBJECTIVES: To assess the risk-benefit of statin therapy, prescribed for the prevention of CVD, in the development of DM. METHODS: In a population-based real-life study, the incidence of DM and CVD were assessed retrospectively among 265,414 subjects aged 40-70 years, 17.9% of whom were treated with statins. Outcomes were evaluated according to retrospectively determined baseline 10 year cardiovascular (CV) mortality risks as defined by the European Systematic COronary Risk Evaluation, statin dose-intensity regimen, and level of drug adherence. RESULTS: From 2010 to 2014, 5157 (1.9%) new cases of CVD and 11,637 (4.4%) of DM were observed. Low-intensity statin therapy with over 50% adherence was associated with increased DM incidence in patients at low or intermediate baseline CV risk, but not in patients at high CV risk. In patients at low CV risk, no CV protective benefit was obtained. The number needed to harm (NNH; incident DM) for low-intensity dose regimens with above 50% adherence was 40. In patients at intermediate and high CV risk, the number needed to treat was 125 and 29; NNH was 50 and 200, respectively. CONCLUSIONS: Prescribing low-dose statins for primary prevention of CVD is beneficial in patients at high risk and may be detrimental in patients at low CV risk. In patients with intermediate CV risk, our data support current recommendations of individualizing treatment decisions.
