Evaluating the contributing factors is crucial to optimize the healthcare and target the intervention. In this study we evaluated the potential for preventing 30-day hospital readmission in a cohort of older patients and identified possible risk factors for readmission.Patients and methods: Diagnosis-Related Group (DRG) codes of patients consecutively hospitalized for acute disease in the Geriatrics Unit of the University Hospital of Pisa within a 1-year window were recorded. All the patients had received a comprehensive geriatric assessment. Crossing and elaboration of the DRG codes was performed by the Potentially Preventable Readmission Grouping software (3M™ Corporation). DRG codes were classified as stand-alone admissions (SA), index admissions (IA) and potentially preventable readmissions (PPR) within a time window of 30 days after discharge.Results: In total, 1263 SA and 171 IA were identified, with an overall PPR rate of 11.9%. Hospitalizations were significantly longer in IA and PPR than SA (p

Infectious diseases are a major public health concern. In recent decades, there has been a succession of bacterial and viral diseases, which when added to the endemic diseases found in certain areas of the world, can become a global health problem. In emergency medicine we talk a lot about Mass Casualty Incident (MCI) preparedness, but the main focus today is bio-preparedness. Therefore, especially after the Ebola experience, much investment has been made in the development of Biocontainment Units (BCUs). At present, in Italy there are no national realities that have experimented the construction of a completely new biocontainment units detached from the Emergency Department (ED) RNPP-funded. Given this, the project of the Azienda Ospedaliero-Universitaria Pisana (AOUP) is to make renovations on existing ED structure and build an entire new facility for biocontainment.

Improving the cleaning and disinfection of high-touch surfaces is one of the core components of reducing healthcare-associated infections. The effectiveness of an enhanced protocol applying UV-C irradiation for terminal room disinfection between two successive patients was evaluated. Twenty high-touch surfaces in different critical areas were sampled according to ISO 14698-1, both immediately pre- and post-cleaning and disinfection standard operating protocol (SOP) and after UV-C disinfection (160 sampling sites in each condition, 480 in total). Dosimeters were applied at the sites to assess the dose emitted. A total of 64.3% (103/160) of the sampling sites tested after SOP were positive, whereas only 17.5% (28/160) were positive after UV-C. According to the national hygienic standards for health-care setting, 9.3% (15/160) resulted in being non-compliant after SOP and only 1.2% (2/160) were non-compliant after UV-C disinfection. Operation theaters was the setting that resulted in being less compliant with the standard limit (≤15 colony-forming unit/24 cm 2 ) after SOP (12%, 14/120 sampling sites) and where the UV-C treatment showed the highest effectiveness (1.6%, 2/120). The addition of UV-C disinfection to the standard cleaning and disinfection procedure had effective results in reducing hygiene failures.

Background: In the past few decades, the inadequate reprocessing of bronchoscopes has been associated with several serious outbreaks caused by multidrug-resistant microorganisms. In this study we evaluated the improvement in the quality of reprocessing in a Bronchoscopy Unit (BU), after the introduction of a new procedure., Methods: In 2019, observational and clinical audits were conducted in the BU. After the introduction of an improved procedure in 2020, a microbiological surveillance plan was implemented in 2021., Results: In 2019, 13 of 22 bronchoscopes (59%) resulted as non-compliant, 18% as high concern organisms (HCO) and 36.4% as high microbial count (≥100 CFU/all channels) and HCO. The most frequent microorganisms were Staphylococcus aureus (38.5%) and NDM-producing Klebsiella pneumoniae (15.4%). The bronchoscopes were stored inside their transport cases, which in some cases were found to be contaminated by the same strains isolated on the bronchoscopes ( Enterobacter gergoviae and Vibrio alginolyticus ). In 2021, all 31 bronchoscopes were sampled at least three times and 13/99 (13.1%) resulted as non-compliant, mostly K. pneumoniae (4.04%). Contamination level increases weakly in bronchoscopes in use for more than 14 years (R = 0.32)., Conclusions: The adoption of an improved reprocessing procedure decreased the non-compliance of bronchoscopes, increasing the quality of the process and patient safety.

With the development of SARS-CoV-2 vaccines, many authors started evaluating the immunization efficacy of the available vaccines mainly through sero-positivity tests or by a quantitative assessment of the IgG against the spike protein of SARS-CoV-2 virus in vaccinated subjects. In this work, we compared the titers resulting from vaccination and tried to understand the potential factors affecting the immune response to the available SARS-CoV-2 vaccines. This study was conducted on 670 volunteers employed at the University of Pisa and undergoing a health surveillance program at the University Hospital of Pisa. For each participant, 10 mL of blood, information about contacts with confirmed cases of COVID-19, age, sex, SARS-CoV-2 vaccination status, previous SARS-CoV-2 infection and symptoms, type of vaccine and the date of administration were collected. In the multivariate analysis, the type of vaccine, the presence of symptoms in SARS-CoV-2 positive individuals, and the distance from the second dose significantly affected the antibody titer; the combined vaccination resulted in a faster decay over time compared with the other types of vaccination. No significant differences were observed between Spikevax and Comirnaty (p > 0.05), while the antibody levels remain more stable in subjects undergoing Vaxzevria vaccination (p < 0.01) compared with mRNA-based ones.

The initial phases of COVID-19 emergency in Italy highlighted the technical delay that the national health system has accumulated in health services digitalization. Italian hospitals rapidly applied a demand systems for virtual health services based on tele-triage, tele-consultation and tele-visits procedures. This led, in the following months, the integration of virtual healthcare services applicable to the Azienda Ospedaliero Universitaria Pisa (AOUP). In particular, BCure system represents an important technological investment for the remote management of care protocols and the analysis of the complete use of health services. This is a unique system for sharing information between specialists, general practitioners and patients.

According to a modern definition, the patient's medical record is a tool shared by health-care professionals whose purpose is to support the planning, providing and documenting of patient-centred care. The requirements and regulations of medical records, which date back to the sixties, need now be adapted to more recent organisational models based on different levels of care intensity and strongly integrated patient-oriented care approaches designed to create connectivity, alignment and collaboration within and between different professional fields. On this basis, the SS. Cosma and Damiano Hospital Chief Physician endorsed a multiprofessional project providing for the complete reorganisation of surgical activities according to the above-mentioned approach and, at the same time, for the elaboration of an "integrated" medical record, capable of overcoming the traditional separation between medical and nursing documents. This paper presents the results of a long period of complex teamwork consisting in revising and sharing a new medical record model based on principles of professional integration and patient-centredness in health-care provision.

A retrospective analysis of hospital medical records was performed jointly by the Medicolegal department of the Pistoia Local Health Unit N. 3 and by the management of the SS. Cosma and Damiano di Pescia Hospital. Evaluation was based on ANDEM criteria, JCAHO standards, and the 1992 discharge abstract guidelines of the Italian Health Ministry. In the first phase of the study, data were collected and processed for each hospital ward and then discussed with clinicians and audited. After auditing, appropriate actions were agreed upon for correcting identified problems. Approximately one year later a second smaller sample of medical records was evaluated and a higher compliance rate with the established corrective actions was found in all wards for all data categories. In this study the evaluation of medical records can be considered in the wider context of risk management, a multidisciplinary process directed towards identifying and monitoring risk through the use of appropriate quality indicators.

The poor vaccination coverage among health-care workers in a hospital, resulted from a self-administered questionnaire, showed the necessity to improve educational efforts and to promote vaccination campaign.

The diagnostic value of radioisotopic cerebral angioscintigraphy (R.A.) and of Doppler CW (D.C.W.) techniques to identify stenosis of the internal carotid artery in its extracranial course was studied in 97 patients with ischaemic lesions (50 T.I.A. and 47 Complete Stroke). The results of R.A. and D.C.W. were compared with those of contrast carotid-angiography (C.A.). C.A. revealed stenosis above 50% or complete occlusion in 22% of cases, whereas D.C.W. and R.A. showed flow reduction in 27% and 48% of the cases respectively. In T.I.A., C.A. positivity went down to 8%; D.C.W. to 16%; and R.A. to 34%. In "Complete Stroke" positivity was 36% for C.A.; 41% for D.C.W.; and 62% for R.A. There was a high number of false positive findings with D.C.W. (8) but even more with R.A. (27). False negative findings occurred only in two cases with R.A. These data confirm the diagnostic value of these two noninvasive techniques to identify haemodynamically carotid stenosis. The use of both methods can reduce error due to false negativity. The rather marked frequency of false positivity, particularly with reference to R.A. doesn't affect the diagnostic value of the two methods.

The Authors take into consideration some important forms of vascular and tumoral pathology of neurosurgical interest which can affect pregnant women. Some criteria of urgency or delay of the surgical treatment are proposed in the attempt of saving the mother's and the foetus' life.

The Authors have investigated the significance and the limits of the directional Doppler method in a group of subjects affected by internal carotid obstruction in various sites and degree. On the basis of the obtained results the Authors point out how this method represents a concrete progress in the field of non invasive diagnosis of the insufficiency of this artery.

Post-traumatic thrombosis of the middle cerebral artery (MCA) is uncommon: only 39 cases were found in the literature. In the present report, eight cases of post-traumatic MCA thrombosis are analyzed and compared with other reported cases. The symptoms can be easily confused with those of expanding intracranial hematoma. Although ancillary noninvasive diagnostic methods are helpful, cerebral angiography confirms the diagnosis. The morbidity and mortality rates are high, and treatment has been mainly supportive. The low mortality in the present study may be related to the absence of severe head or other trauma. Possible cerebral revascularization procedures are also discussed.

The authors report their experience in six cases of head surgery for the simultaneous reconstruction of skin, bone and dura mater. They recommend the use of teflon as a dural substitute and the autogenous bone opercolum, boiled to have it free from cancer cells or infection.
