Background: Pneumocystis jirovecii pneumonia (PJP) is an opportunistic infection in immunocompromised patients. Clusters of PJP, especially among organ transplant recipients in clinic settings were described. Data regarding nosocomial PJP infection among inpatients are limited.

Objectives: To assess the magnitude and characteristics of inpatient healthcare-associated PJP infection (HCA-PJP) in HIV-negative patients.

Methods: A retrospective chart review of hospitalized PJP patients was performed to identify HCA-PJP. The study was performed at six medical centers in Israel from 2006 to 2016. HCA-PJP was defined as cases of hospital-onset or those with documented contact with a PJP patient. We reviewed and cross-matched temporal and spatial co-locations of patients. Clinical laboratory characteristics and outcomes were compared.

Results: Seventy-six cases of PJP were identified. Median age was 63.7 years; 64% men; 44% hematological malignancies; 18% inflammatory diseases; and 61% steroid usage. Thirty-two patients (42%) were defined as HCA-PJP: 18/32 (23.6%) were hospitalized at onset and 14/32 (18.4%) had a previous encounter with a PJP patient. Time from onset of symptoms to diagnosis was shorter in HCA-PJP vs. community-PJP (3.25 vs. 11.23 days, P = 0.009). In multivariate analysis, dyspnea at presentation (odds ratio [OR] 16.79, 95% confidence interval [95%CI] 1.78–157.95) and a tendency toward higher rate of ventilator support (72% vs. 52%, P = 0.07, OR 5.18, 95%CI 0.7–30.3) were independently associated with HCA-PJP, implying abrupt disease progression in HCA-PJP.

Conclusion: HCA-PJP was common. A high level of suspicion for PJP among selected patients with nosocomial respiratory infection is warranted. Isolation of PJP patients should be considered

Background: Although indwelling catheters are increasingly used in modern medicine, they can be a source of microbial contamination and hard-to-treat biofilms, which jeopardize patient lives. At times 70% ethanol is used as a catheter-lock solution due to its bactericidal properties. However, high concentrations of ethanol can result in adverse effects and in malfunction of the catheters.

Objective: To determine whether low concentrations of ethanol can prevent and treat biofilms of Pseudomonas aeruginosa.

Methods: Ethanol was tested at a concentration range of 0.625–80% against laboratory and clinical isolates of P. aeruginosa for various time periods (2–48 hours). The following parameters were evaluated following ethanol exposure: prevention of biofilm formation, reduction of biofilm metabolic activity, and inhibition of biofilm regrowth.

Results: Exposing P. aeruginosa to twofold ethanol gradients demonstrated a significant biofilm inhibition at concentrations as low as 2.5%. Treating pre-formed biofilms of P. aeruginosa with 20% ethanol for 4 hours caused a sharp decay in the metabolic activity of both the laboratory and clinical P. aeruginosa isolates. In addition, treating mature biofilms with 20% ethanol prevented the regrowth of bacteria encased within it.

Conclusions: Low ethanol concentrations (2.5%) can prevent in vitro biofilm formation of P. aeruginosa. Treatment of previously formed biofilms can be achieved using 20% ethanol, thereby keeping the catheters intact and avoiding complications that can result from high ethanol concentrations.

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.

Global trends, such as the population aging, the increase of chronic morbidity, soaring costs of healthcare services, and work overload in hospitals raise the need to find innovative solutions for providing quality medical services. One solution adopted by healthcare systems around the world is "home hospitalization," that is, providing an array of necessary health services in the patient's home, instead of in the hospital department. The aim of this focus article is to explore the spread of home hospitalization worldwide and examine the challenges and pathways for its adoption and implementation. Many countries, including the United States, Canada, the United Kingdom, and Australia, operate home-based hospitalization programs. In Israel, the service is in its infancy, but in view of the extreme workload and the high mortality rate from infections in acute care hospitals, home hospitalization has recently gained public interest and political support, which may encourage its further development.

Background: In Israel, coronary heart disease mortality rates are significantly higher among the Arab population than the Jewish population. Dyslipidemia prevention should begin in childhood.

Objectives: To identify sociodemographic disparities in the preventive health measurement of lipid profile testing and lipoprotein levels among Israeli children and adolescents.

Methods: A cross-sectional analysis of 1.2 million children and adolescents insured by Clalit Health Services between 2007 and 2011 was conducted using sociodemographic data and serum lipid concentrations.

Results: Overall, 10.1% individuals had undergone lipid testing. Those with male sex (odds ratio [OR] = 0.813, 95% confidence interval [95%CI] 0.809–0.816), Arab ethnicity (OR = 0.952, 95%CI 0.941–0.963), and low socioeconomic status (SES) (OR = 0.740, 95%CI 0.728–0.752) were less likely to be tested. By 2010, differences among economic sectors narrowed and Arab children were more likely to be tested (OR = 1.039, 95%CI 1.035–1.044). Girls had higher total cholesterol, triglyceride, low-density lipoprotein-cholesterol, and non-high-density lipoprotein-cholesterol levels compared to boys (P < 0.001). Jewish children had higher cholesterol and low-density and high-density lipoprotein-cholesterol, as well as lower triglyceride levels than Arabs (P < 0.001). Children with low SES had lower cholesterol, low-density and high-density lipoprotein-cholesterol, and non-high-density lipoprotein-cholesterol levels (P < 0.001).

Conclusions: We found that boys, Arab children, and those with low SES were less likely to be tested. Over time there was a gradual reduction in these disparities. Publicly sponsored healthcare services can diminish disparities in the provision of preventive health among diverse socioeconomic groups that comprise the national population.

Background: Lower extremities ulcers (LEU) are associated with considerable morbidity and mortality. With longer life expectancy, the prevalence of LEU in developed countries is assumed to grow, necessitating an increased demand for treatment by specialists. 

Objectives: To compare the effectiveness of a telemedicine video conferencing modality with the conventional face-to-face treatment of LEU. 

Methods: The study was conducted in conjunction with a two-million member healthcare organization in Israel (Maccabi Healthcare Services). Consecutive visits of patients to wound care specialists during a 12-month observation period reviewed in 2015 were valuated. A nurse-assisted setting was implemented during all treatment sessions. The same specialist supervised patients in both modalities. 

Results: A sample of 111 patients (n=55 in the telemedicine group; n=56 in the face-to-face group) with 593 visits was analyzed. No significant difference in healing of LEU (78.2% in telemedicine vs. 75.0% in face-to-face) was detected, P = 0.823. A reduced number of visits in telemedicine (4.36 ± 2.36) compared to the face-to-face care (6.32 ± 4.17) was shown, P = 0.003. Non-inferiority of telemedicine demonstrated within the Δ = 15% range limits and 80% statistical power was demonstrated. 

Conclusions: Compared to the usual face-to-face method, synchronous video conferencing-based telemedicine may be a feasible and efficient method for LEU management. 

 

Background: The number of cancer survivors has been increasing worldwide and is now approximately 32.6 million and growing. Cancer survivors present a challenge to health care providers because of their higher susceptibility to long-term health outcomes related to their primary disease and treatment.

Objective: To report on the number of cancer survivors and incident cancer cases in the period 1960–2009 in Israel, in order to provide data on the scope of the challenge Israel’s health care funds face.

Methods: The Israel National Cancer Registry (INCR) database was used to identify new cancer cases diagnosed during the period 1960–2009. Lifetable analysis was used to assess changes in cumulative survival and population prevalence of cancer survivors throughout the 50 year study period.

Results: Almost 600,000 invasive cancer cases were diagnosed during the period 1960–2009 (overall absolute survival rate 54%). Within this time period, the number of new patients diagnosed with cancer increased fivefold and that of cancer survivors ninefold. The absolute survival of cancer patients and the prevalence of cancer survivors in the general population significantly increased with time from 34% and 0.5%, respectively (1960–1969), to 62% and 1.9%, respectively (2000–2009). Cumulative absolute survival for 5, 10 and 15 years following diagnosis increased with time as well.

Conclusions: The INCR database is useful to assess progress in the war against cancer. The growing numbers of cancer survivors in Israel present a challenge to the national health and social services system.

Background: Healthcare behavior occurs within the context of the family unit. Little research has investigated the influences among adult family members regarding their use of medical care services.

Objectives: To investigate the effects of maternal attendance patterns and maternal self-assessed health status on those of adult children.

Methods: This study was a retrospective cohort, analyzing both patient records for physician visits and mailed self-administered questionnaires regarding subjective health assessment. We evaluated a unique study group of multi-generational families with free and equal access to medical services at a primary care kibbutz clinic in Israel. This enabled an exclusive focus on the association between the use of healthcare by mothers and their grown children.

Results: Controlling for the subjects' age, gender and number of chronic diagnoses, a significant association exists between the family physician visit rates of a mother and those of her grown offspring (P = 0.03). Low self-health assessment is associated with higher levels of physician utilization (P = 0.003). Maternal self-health evaluation is associated with her adult children's own self-health evaluation (odds ratio 5.9, P = 0.04) and their rates of physician utilization (one additional offspring visit per year for low maternal self-health, P = 0.02).

Conclusions: A mother’s behavior patterns measured via self-rated health status and physician visit rates serve as a proxy for maternal attitudes regarding healthcare, and these attitudes are possibly imparted to her children for life. This study provides unique evidence for a maternal health behavior effect on grown children, and enables a more complete understanding of families attending the primary care clinic.
 

Background: Anesthesiology is a vital specialty that permits the safe and humane performance of painful procedures. Most Israeli anesthesiologist are immigrants, while only a minimal number of Israeli medical school graduates enter the specialty. Unfortunately, the supply of immigrant physicians is declining due to falling immigration rates.

Objectives: To examine the current Israeli anesthesiology workforce and project future needs.

Methods: Demographic and professional information about Israeli hospital anesthesiologists was solicited from anesthesiology department heads. Data were also gathered about the past, present and projected future growth, age distribution and birth rate of the Israeli population. Needs and demand-based analyses were used to project future anesthesiology workforce requirements.

Results: Data about 711 anesthesiologists were obtained from 30 hospital anesthesiology department heads. Eighty-seven anesthesiologists (12.2%) graduated from Israeli medical schools and 459 (64.6%) graduated from medical schools in the former Soviet Union. Among the 154 anesthesiology residents were ≤ 40 years old, and only 13 (8.4%) graduated from Israeli medical schools There are approximately 10.8 anesthesiologists per 100,000 population. Projections for 2005–2015 revealed a need for 250–300 new anesthesiologists.
Conclusions: The anesthesiology workforce is predominantly composed of immigrants. This has vast implications for the future viability of the specialty because of the continuing reduction in immigration, the lack of interest in the specialty by Israeli medical school graduates, and the projected need for many new anesthesiologists to replace retirees and to provide care to a growing and aging population
