Sismed increases efficiency and profitability of preventive and occupational medicine management at the Resnati hospital, part of the San Raffaele healthcare system in Milan

NSI, Nier Soluzioni Informatiche, is a company that specializes in providing software and infrastructure solutions. Since its founding in 2002, the company has collaborated with San Raffaele Srl and the healthcare system's various institutions. And it was for one of these institutions, the San Raffaele Resnati hospital, that in 2008 NSI entirely designed and created Sismed, an IT system for comprehensive management of occupational and preventive medicine services.

The goal was to develop a software solutioncapable of adapting to the needs of customers (including the Municipality of Milan, with over 17,000 employees), supporting all users in the performance of their work and making processes more fluid and efficient.

An analysis of the work processes and individual duties involved revealed numerous and varied needs on the part of the Resnati hospital:

  • Management of over 150,000 patient records for a total of almost 1500 enterprise clients registered in the system, with over 1500 medical treatments provided daily.
  • The need to manage over 700 workplace inspections in a centralized way, reducing the time it takes to coordinate them.

The need to optimize visit completion times and, above all, patient wait times between visits, especially in cases where a patient has to complete multiple visits in the same day.

The need for a software application readily accessible by over 500 users with different roles, simultaneously connected to the system from different locations. Administrators, work inspectors, healthcare professionals, and doctors are just some of the key users of the system.

To ensure the project's success, there were two factors of maximum importance that NSI had to consider and properly address. The first was a flexible working method that would allow for adapting parts of the project already developed to new insights that might arise during the operational analysis. The second was an advanced development environment that would allow concentrating the team's efforts on dynamic software modeling.

Instant Developer allowed us to manage the complexity of the project and shorten prototyping times. In fact, the first version of Sismed, with very early features, was delivered to the customer in just three weeks. Without InDe, we would never have been able to work using an agile methodology, which involves heavy interaction and collaboration with the customer and continuous redefinition of the project specifications.

Characteristics of the project

NSI started with simple observation of the inner workings of the hospital and a precise and accurate analysis of the status quo in terms of administrative, commercial, and healthcare management, interweaving the needs and problems encountered by users, even analyzing the paths taken by patients through the building, from admission to discharge. In just three weeks, NSI delivered the first functional prototype of the system, built as a web-based application. To date, Sismed has the following features:

  • It can manage the patient visit cycle, from admission to discharge, interweaving data from multiple sources and integrating complete management of all patient-related documents (certificates, tickets, etc.).
  • It allows managing patients with maximum levels of privacy, identifying patients with a number for some types of users (thus preserving their anonymity).
  • It is the first hospital management system that not only handles coordination between the various individuals in the hospital, but also has algorithms that track and optimize the path taken by patients inside the building.
  • It is integrated with external systems, such as the diagnostic laboratory system and the billing system, to automate outsourcing of lab work and receipt of reports, thus improving accuracy.

Sismed was a complex project that provided significant benefits to the San Raffaele healthcare system. Today, thanks to Sismed and NSI's analysis of logistical paths, occupational medicine doctors at the hospital perform an average five visits per hour versus the three allowed by the old system in the best cases, an increase of 40%. Also, the new system is able to organize 15 medical treatments in just four hours.
