Given the high hospital costs, the increasing clinical complexity and the overcrowding of emergency departments, it is crucial to improve the efficiency of medical admissions. We aimed at isolating organizational drivers potentially targetable through a widespread improvement action. We studied all medical admissions in a large tertiary referral hospital from January 1st to December 31st, 2018. Data were retrieved from the administrative database. Available information included age, sex, type (urgent or elective) and Unit of admission, number of internal transfers, main ICD-9 diagnosis, presence of cancer among diagnoses, surgical or medical code, type of discharge, month, day and hour of admission and discharge. National Ministry of Health database was used for comparisons. 8099 admissions were analyzed. Urgent admissions (80.5% of the total) were responsible for longer stays and were the object of the multivariate analysis. The variables most influencing length-of-stay (LOS) were internal transfers and assisted discharge: they contributed, respectively, to 62% and 40% prolongation of LOS. Also, the daily and weekly kinetics of admission accounted for a significant amount of variation in LOS. Long admissions (≥ 30 days) accounted for the 15.5% of total bed availability. Type of discharge and internal transfers were again among the major determinants. A few factors involved in LOS strictly depend on the organizational environment and are potentially modifiable. Re-engineering should be focused on making more efficient internal and external transitions and at ensuring continuity of the clinical process throughout the day and the week.

To investigate percutaneous exposures to HIV in the highly active antiretroviral therapy (HAART) era, we performed an analysis of all percutaneous exposures reported from January 1994 to December 1998 in 18 Italian acute-care hospitals. Frequency and rate per 100 prevalent AIDS cases of HIV exposures decreased by 40% (from 4.3% to 2.6%, and from 1.0% to 0.6%, respectively; p<0.001), which were mainly those related to the insertion/manipulation of peripheral vascular access devices (from 7.2% to 4.8%; p=0.05). We conclude that the benefits of HAART have changed the complexity of care required and therefore, the number and type of procedures performed on HIV patients that place the HCW at risk of injury.

Pharmacological tests are often indispensable in non-invasive polycardiographic diagnosis. Their advantages include easy execution, repeatability, and the absence of significant side-effects. Amyl nitrate, angiotensin and isoproterenol are most commonly employed for this purpose. Cases in which such tests enabled a correct evaluation of valve disease, congenital heart disease, and malfunction of a valve prosthesis to be made are presented.

The purpose of this study was to examine the clinical course of dilated (congestive) cardiomyopathy (DCM) and to identify the factors of prognostic significance. Between January 1969 and April 1982, 137 patients with a diagnosis of dilated cardiomyopathy were followed-up for a mean period of 48,7 +/- 40 months. Mean duration of illness before the first study was 15,5 months. A history of excessive alcohol intake was present in 22% of the patients and an influenza like syndrome in 9%. At diagnosis most of the patients were in NYHA functional class IV (43,5%) and III (35%). The 5-year survival rate was 45%, the mean annual mortality rate 10,2% and the highest mortality rate 14% in the second and third year. One hundred and seven patients (78%) progressed to major complications (worsening heart failure and death), while thirty patients (22%) showed stable or even improved conditions. Systemic or pulmonary emboli occurred in 18% of the patients, with a significant prevalence in patients with atrial fibrillation (p less than 0,05). Prognosis was unfavorably affected by the following factors: bi-ventricular heart failure as first clinical manifestation (p less than 0,01), intraventricular conduction delay (LBBB, LAHB) (p less than 0,05), significant cardiomegaly (cardiothoracic ratio greater than 0,53, p less than 0,001), left ventricular dysfunction (left ventricular fractional shortening less than 14%, p less than 0,005, left ventricular end-diastolic pressure greater than 17 mmHg, p less than 0,05, left ventricular end diastolic volume greater than 185 ml/m2, p less than 0,001, cardiac index less than 2,2/min/m2, p less than 0,001).
