Emergency Department crowding and hospital bed shortage: is Lean a smart answer? A systematic review.

OBJECTIVE: Emergency Departments (EDs) worldwide face the challenges of crowding, waiting times, and cost containment. This review aims to provide a synthesis of the current literature focused on how Lean Thinking Principles and tools can be applied in an ED to address overcrowding and hospital admissions. MATERIALS AND METHODS: Primary studies showing Lean interventions and implementation in ED visits, not requiring additional resources measuring specific outcomes (i.e. length of stay, patient volume, patient satisfaction, waiting times for the first visit, waiting times for diagnostic results, left without being seen) were selected. PubMed, Scopus, CINAHL, EconLit, NHS Economic Evaluation Database, Business Sources Complete, and Health Technology Assessment were used to conduct searches. Full-text articles of all potentially relevant publications were reviewed for eligibility. Discrepancies were resolved through discussion by all reviewers. Quality assessment and critical appraisal of selected studies were also evaluated by applying the Quality Improvement Minimum Quality Criteria Set. RESULTS: Nine before-and-after studies met these eligibility criteria. Management of patient flow was the main intervention. Almost all studies showed EDs performance improvement: increased patient volume, decreased length of stay and number of patients left without being seen, reduced costs, and increased patient satisfaction. Only one case reported worse results after Lean intervention implementation. CONCLUSIONS: Though Lean Principals have been used in healthcare for many years conclusion of their effects could still not be drawn. Surely, human-centered approach, top management support, work standardization, resources allocation and adaptation to the local context seem to be crucial for success. Furthermore, higher quality studies are needed: specific research design, appropriate statistical tests and outcome measures are needed. Before large-scale implementation, further studies are needed to evaluate the true ability of Lean interventions to improve healthcare delivery.

Protective role of the Mediterranean diet on several cardiovascular risk factors: evidence from Sicily, southern Italy.

BACKGROUND AND AIMS: Epidemiological studies conducted in European countries demonstrated that the adoption of a Mediterranean diet protect against clustered risk factors but those evaluating such benefits specifically in southern Italy are scarce. Thus, the aim of this study was to assess the association between the adherence to the Mediterranean diet and cardiovascular risk factors obesity, diabetes, and hypertension. METHODS AND RESULTS: A cross-sectional population-based survey including 3090 subjects was conducted in Sicily, southern Italy. Food intake was evaluated through a validated food frequency questionnaire and adherence to the dietary pattern was assessed using the MedDietScore. Linear and logistic regression models were performed to estimate odds ratios (ORs) and respective confidence intervals (CIs). After adjusting for confounding factors such as age and gender, participants in the highest tertile of the MedDietScore were less likely to be obese (OR 0.35, 95% CI: 0.24-0.51), hypertensive (OR 0.73, 95% CI: 0.55-0.97), and diabetic (OR 0.43, 95% CI: 0.24-0.77). Linear inverse relation between the MedDietScore and BMI (r(2) = 0.34, P < 0.001), waist circumference (r(2) = 0.17, P < 0.001), and waist-to-hip ratio (r(2) = 0.06, P < 0.001) was found. CONCLUSION: Despite the prevalence rates of nutrition-related diseases are high in Sicily, greater adherence to the Mediterranean dietary pattern is still associated with a better health status.

Pattern of antibiotic use in the community: νon-adherence and self-prescription rates in an Italian urban population.

The aim of the present study was to assess the pattern of antibiotic use in a community setting of an urban area of Italy and identify factors that affect adherence to their use. By using a questionnaire-based survey, we collected 1,269 interviews and performed analysis on those patients who had their last course of antibiotic within the past 12 months (956 subjects). Among the subjects reporting that they had not followed their last antibiotic course as prescribed, 14.7% stopped therapy early, 5.4% modified the dosage, and 5% changed the prescribed antibiotic. Approximately 23% of the subjects declared that they self-prescribed antibiotics. After adjusting for all covariates, major predictors for the self-prescription of antibiotics were younger age, female gender and higher socioeconomic and educational status. Conversely, both low educational and socioeconomic status were associated with a higher risk of non-adherence to physician indications. The findings of this study assessed the widespread pattern of poor antibiotic-taking behavior and provides important implications for understanding the targets of future educational campaigns to control the use and misuse of antibiotics.

[Adherence to antihypertensive and lipid-lowering medications: a problem of public health, not yet resolved]. / Aderenza alla terapia con farmaci antipertensivi e ipolipemizzanti: un problema di sanità pubblica ancora irrisolto.

Assessment of compliance in patients with relevant comorbidity condition, above all those at high cardiovascular risk, is especially relevant because their clinical condition can be considerably mitigated by treatment with concomitant antihypertensive (AH) and lipid-lowering (LL) medications. The aim of the study was to evaluate patterns and predictors of adherence and persistence with concomitant AH and LL therapy. This retrospective cohort study included 363 enrolled from database of 3 physicians who initiated treatment with AH and LL therapy between January 2007 and January 2010. Adherence was measured as the proportion of days covered in 3-month intervals and patients were considered adherent if they had filled prescriptions for at least 80% of the period. Persistence was measured as absence of discontinuation define as > 30 days between a filled prescription and the subsequent claim. A multivariate analysis with a Cox regression model was performed to evaluate potential predictors of adherence and persistence. Finally, patients outcome was evaluated to assess potential association with adherence and persistence with AH and LL therapy. The mean percentage of patients adherent with both AH and LL medications was 39%, declining from 47% to 31%. The mean percentage of persistence was 43%. After adjustment for variables of interest, major predictors of adherence and persistence were the number of concomitant prescriptions, age of patients, gender time between start of AH and LL therapy, and gravity of coronary disease. Finally, adherent and persistent patients had significant lower blood pressure compared to other subjects. Adherence and persistence with concomitant AH and LL therapy was poor and declined over time. Interventions to improve these attitudes and to contain costs affecting a limited health budget are needed.
