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.

Background: Catastrophic life events are associated with the occurrence of cardiovascular incidents and worsening of the clinical course following such events.

Objectives: To evaluate the characteristics and long-term prognosis of Holocaust survivors presenting with acute myocardial infarction (AMI) compared to non-Holocaust survivors.

Methods: Israeli Jews who were born before 1941 and had been admitted to a tertiary medical center due to AMI during the period 2002–2012 were studied. Holocaust survivors were compared with non-Holocaust survivor controls using individual age matching.

Results: Overall 305 age-matched pairs were followed for up to 10 years after AMI. We found a higher prevalence of depression (5.9% vs. 3.3%, P = 0.045) yet a similar rate of cardiovascular risk factors, non-cardiovascular co-morbidity, severity of coronary artery disease, and in-hospital complications in survivors compared to controls. Throughout the follow-up period, similar mortality rates (62.95% vs. 63.9%, P = 0.801) and reduced cumulative mortality (0.9 vs. 0.96, HR = 0.780, 95%CI 0.636–0.956, P = 0.016) were found among survivors compared to age-matched controls, respectively. However, in a multivariate analysis survival was not found to be an independent predictor of mortality, although some tendency towards reduced mortality was seen (AdjHR = 0.84, 95%CI 0.68–1.03, P = 0.094). Depression disorder was associated with a 77.9% increase in the risk for mortality. 

Conclusions: Holocaust survivors presenting with AMI were older and had a higher prevalence of depression than controls. No excessive, and possibly even mildly improved, risk of mortality was observed in survivors compared with controls presenting with AMI. Possibly, specific traits that are associated with surviving catastrophic events counter the excess risk of such events following AMI.

 

Background: During military escalations emergency departments provide treatment both to victims of conflict-related injuries and to routine admissions. This requires special deployment by the hospitals to optimize utilization of resources.

Objectives: To evaluate “routine” visits to the ED[1] during Operation Cast Lead in Israel in 2008–2009.

Methods: We obtained data regarding routine visits to the ED at Soroka University Medical Center throughout OCL[2]. The visits one month before and after OCL and the corresponding periods one year previous served as controls.

Results: The mean number of daily visits throughout the study period (126 days) was 506 ± 80.9, which was significantly lower during OCL (443.5 ± 82) compared with the reference periods (P < 0.001). Compared to the reference periods, during OCL the relative rates were higher among Bedouins, visitors from the region closest to the Gaza Strip (< 30 km), patients transported to the ED by ambulance and patients of employment age; the rates were lower among children. No difference in the different periods was found in the rate of women patients, distance of residence from Beer Sheva, rate of patients referred to the ED by a community physician, and hour of arrival. The overall in-hospital admission rate increased during OCL, mainly in the internal medicine and the obstetric departments. There was no change in the number of in-hospital births during OCL; however, the rate of preterm labors (32–36 weeks) decreased by 41% (P = 0.013).

Conclusions: Throughout OCL the number of routine ED visits decreased significantly compared to the control periods. This finding could help to optimize the utilization of hospital resources during similar periods.
