Development of a web based monitoring system for safety and activity analysis in operating theatres.

BACKGROUND: The management and the monitoring of the operating rooms on the part of the general management have the objective of optimizing their use and maximizing the internal safety. The expenses owed to their safe use represent, besides reimbursements coming from the surgical activity, important factors for the analysis of the medical facility. OBJECTIVE: Given that it is not possible to reduce the safety, it is necessary to develop supporting systems with the aim to enhance and optimize the use of the rooms. METHODS: The developed analysis model of the operating rooms in this study is based on the specific performance indicators and allows the effective monitoring of both the parameters that influence the safety (environmental, microbiological parameters) and those that influence the efficiency of the usage (employment rate, delays, necessary formalities, etc.). This allows you to have a systematic dashboard on hand for all of the OTs and, thus, organize the intervention schedules and more appropriate improvements. RESULTS: A monitoring dashboard has been achieved, accessible from any platform and any device, capable of aggregating hospital information. The undertaken organizational modifications, through the use of the dashboard, have allowed for an average annual savings of 29.52 minutes per intervention and increase the use of the ORs of 5%. The increment of the employment rate and the optimization of the operating room have allowed for savings of around $299,88 for every intervention carried out in 2013, corresponding to an annual savings of $343,362,60. CONCLUSIONS: Integration dashboards, as the one proposed in this study as a prototype, represent a governance model of economically sustainable healthcare systems capable of guiding the hospital management in the choices and in the implementation of the most efficient organizational modifications.

Development of sustainable models for technology evaluation in hospital.

BACKGROUND: This paper reports the development of standard techniques for technology evaluation in hospital carried out at the Florence Teaching Hospital Careggi (AOUC), where, as a complex system, the technological evaluation is a strategic and essential element for the maintenance of high-quality clinical activity and maximization of available resources. OBJECTIVE: The aim of this paper has been the development of a system of economically sustainable models for the implementation of HTA and HS analyses in the hospital environment as well as presenting, in addition to a valid scientific resilience, the methodological and temporary flexibility to satisfy needs of hospital decision-makers. METHODS: The evaluation models call for 3 main phases: an initial analysis of the in-hospital request, a collection of data, and finally a draft of a specific, easily usable set of reports. RESULTS: Three standardized and tested models of evaluation were developed, which, in relation to the objective of the request and schedule of the assignment, provide for the production of a speedy report (1-week), an intermediate report (1-month), or a extensive report typical of classical studies of hospital based HTA (1-year). It is then related to the evaluation model of the IORT (Intra-Operative Radiation Therapy) technology. DISCUSSIONS AND CONCLUSION: The developed models have permitted the construction, using personnel and laboratories within the hospital, of an evaluation system reliable and responsive to the HOSPITAL's temporary needs based on the HS and HTA analyses in the hospital environment. Regarding the applicable case of IORT, this has shown how in-hospital requests have been satisfied in the preset time: although it establishes expected improvements on the social effect and weight of the illness and reveals a high territorial strategic relevance, the introduction of IORT in the hospital presents some criticalities on the impact on the healthcare organization and the necessity of specific training of medical technologist personnel.

Hospital-based health technology assessment on the use of mitral clips in the treatment of mitral regurgitation.

BACKGROUND: This study, carried out at the Florence Teaching Hospital Careggi (AOUC), reports the technological evaluation, through the use of Health Technology Assessment (HTA), on the application of mitral clips in the treatment of mitral insufficiency. OBJECTIVE: The assessment, carried out by analyzing the clinical, technological, social, procedural, safety and economic elements, sought to answer the following research questions: Evaluation of the general technological status of the mitral clips in the treatment process of mitral regurgitation, with particular reference to traditional methods; and contextualisation of the analyses within the hospital structure, by identifying criticality issues and improvements. METHODS: The methodology was based on the following steps: technological description; areas of evaluation and the selection of Key Performance Indicators; research of scientific facts and the collection of expert opinions; evaluation and reporting of findings. RESULTS: The results are based on an analysis which included a total of 50 indicators, effectively evaluating 86.5% of them, from the least from the clinical sector (80%) to the most in the areas of procedure, safety and social (100%). Traditional surgery (repair or valve replacement) still represents the gold standard for the treatment of mitral regurgitation due to its maturity both on a technological and clinical level. The minimally invasive procedures which use the mitral clips present interesting opportunities both on a social level (minimum stay in hospital and no post-operative rehabilitation) and clinical level, especially as an alternative to medication, even if they are still at an emergent level (the long-term results are unknown) and complex to use. From the clinical point of view they show some interesting findings related to immediate and post-operative mortality (none during the operation and a minor and equal amount 30 days and 12 months later in comparison to traditional methods) whilst economically, despite the fact that the cost of the device is greater than those used in traditional interventions, the cost-refund relationship does not show significant differences compared to the traditional types of treatment. CONCLUSION: The HTA evaluation of minimally invasive technologies that use clips for the treatment of mitral regurgitation shows, in the hospital setting, very interesting results, particularly for inoperable patients, where the clinical and social improvements are significant compared to pharmacological treatments, whilst for 'operable' patients, the traditional techniques are still the most appropriate.

HTA decision support system for sustainable business continuity management in hospitals. The case of surgical activity at the University Hospital in Florence.

BACKGROUND: A fundamental element of the social and safety function of a health structure is the need to guarantee continuity of clinical activity through the continuity of technology. OBJECTIVE: This paper aims to design a Decision Support System (DSS) for medical technology evaluations based on the use of Key Performance Indicators (KPI) in order to provide a multi-disciplinary valuation of a technology in a health structure. METHODS: The methodology used in planning the DSS followed the following key steps: the definition of relevant KPIs, the development of a database to calculate the KPIs, the calculation of the defined KPIs and the resulting study report. Finally, the clinical and economic validation of the system was conducted though a case study of Business Continuity applied in the operating department of the Florence University Hospital AOU Careggi in Italy. RESULTS: A web-based support system was designed for HTA in health structures. The case study enabled Business Continuity Management (BCM) to be implemented in a hospital department in relation to aspects of a single technology and the specific clinical process. Finally, an economic analysis of the procedure was carried out. CONCLUSIONS: The system is useful for decision makers in that it precisely defines which equipment to include in the BCM procedure, using a scale analysis of the specific clinical process in which the equipment is used. In addition, the economic analysis shows how the cost of the procedure is completely covered by the indirect costs which would result from the expenses incurred from a broken device, hence showing the complete auto-sustainability of the methodology.

A robust tool to compare pre- and post-surgical voice quality.

Assessing voice quality by means of objective parameters is of great relevance for clinicians. A large number of indexes have been proposed in literature and in commercially available software tools. However, clinicians commonly resort to a small subset of such indexes, due to difficulties in managing set up options and understanding their meaning. In this paper, the analysis has been limited to few but effective indexes, devoting great effort to their robust and automatic evaluation. Specifically, fundamental frequency (F0), along with its irregularity (Jitter (J) and Relative Average Perturbation (RAP)), noise and formant frequencies, are tracked on voiced parts of the signal only. Mean and std values are also displayed. The underlying high-resolution estimation procedure is further strengthened by an adaptive estimation of the optimal length of signal frames for analysis, linked to varying signal characteristics. Moreover, the new tool allows for automatic analysis of any kind of signal, both as far as F0 range and sampling frequency are concerned, no manual setting being required to the user. This makes the tool feasible for application by non-expert users, also thanks to its simple interface. The proposed approach is applied here to patients suffering from cysts and polyps that underwent micro-laryngoscopic direct exeresis (MLSD).
