# IoT for patient safety: how to choose the best pressure injury prevention solution for Brazilian hospitals > What an IoT patient safety solution needs to prevent pressure injury in Brazilian hospitals: the 6 selection criteria and the published DecSense results. Page: https://preveni.com.br/en/blog/iot-hospital-pressure-injury-prevention/ July 17, 2026 **The best IoT patient safety solution, when the goal is to prevent pressure injury — also called pressure ulcer — is the one that measures what actually happens at the bedside and turns that measurement into team action at the right moment.** In practice, that means three layers working together: a wearable [patient position monitoring sensor](https://preveni.com.br/en/patient-position-monitoring-sensor/) that tracks each patient's position and time 24/7, [management software](https://preveni.com.br/en/pressure-injury-prevention-software/) that cross-checks this data against the nursing care plan and triggers the [repositioning](https://preveni.com.br/en/blog/glossary/#reposicionamento) alert at the exact moment, and automatic measurement of protocol adherence, bed by bed and shift by shift. This guide lays out the six criteria for evaluating any solution — and how Preveni's Brazilian technology meets each one of them. ### On this page 1. What IoT means in patient safety 2.

Where to start: the ICU and a subset of beds ## What IoT means in patient safety IoT (_Internet of Things_) in healthcare is the use of connected sensors to continuously monitor a patient's condition and prompt the team at the right moment, without relying on manual checks and documentation. Applied to patient safety, IoT targets a specific type of failure: care that is correctly prescribed, but whose execution depends on the memory and availability of a team handling many demands at once. The sensor does not get tired, does not forget and does not document from memory at the end of the shift. It measures, the software compares what was measured with what was prescribed, and the team is prompted when — and only when — it is time to act. The data left behind by that operation becomes a management indicator: how much of the protocol was carried out, where and on which shift it slips. ## Why pressure injury is the natural target for IoT in the hospital Pressure injury is one of the most frequent — and most preventable — adverse events during a hospital stay. The main preventive measure for an at-risk patient is repositioning at regular intervals, defined in the nursing care plan. It is exactly the kind of care whose execution is hard to guarantee and hard to audit: it happens many times a day, in every bed, including overnight, and documentation tends to be retrospective. That is why continuous patient position monitoring is the use case where IoT delivers the most clinical and management value: it closes the gap between the written protocol and what actually happens at the bedside. [Technical Note 05/2023](https://preveni.com.br/en/blog/anvisa-technical-note-05-2023-pressure-injuries/) from Anvisa, Brazil's health regulator, itself points to the use of technology as a path to pressure injury prevention. ## The 6 criteria for choosing a solution 1. **Measure the actual position, not just the time.** Fixed-interval alarms and turn clocks remind, but do not verify. The solution must detect which position the patient is in and for how long — if the patient has already been repositioned, the counter resets on its own and the alert does not become noise. 2. **Cross-check the data against the nursing care plan.** Each patient has their own interval and contraindicated positions. The right alert is individualized: it fires according to that patient's care plan, not according to a single rule for the whole unit. 3. **Measure protocol adherence automatically.** What is not measured is not managed. The solution must consolidate repositioning adherence by bed and by shift, with history — objective sensor data, not retrospective manual notes. 4. **Be properly certified in Brazil.** A wireless sensor operates on radio frequency and requires certification by Anatel, Brazil's telecom regulator. Also check the vendor's standing with Anvisa. DecSense is Anatel certified and has a technical opinion from Anvisa. 5. **Have published results.** Ask for evidence presented at a conference or in a scientific publication, with verifiable numbers — not just marketing material. 6. **Rollout, training and support in Brazil.** Technology only moves the indicator if the team uses it. Evaluate care team training, ongoing support and a contracting model that does not stall the project in capital expenditure.

The solution meets the six criteria above with two integrated layers: 1. **The DecSense sensor**: wearable, wireless and attached to the patient's chest, it measures the position and the time spent in each position 24/7, with precise date and time records. It is easy to clean and reusable, Anatel certified and has a technical opinion from Anvisa. See the details on the [patient position monitoring sensor page](https://preveni.com.br/en/patient-position-monitoring-sensor/). 2. **The protocol management software**: it receives sensor data in real time, cross-checks it against the nursing care plan — each patient's interval and contraindicated positions — and alerts the team at the exact moment for repositioning. Protocol adherence is consolidated automatically by bed and by shift, on an at-a-glance management dashboard, with documentation in the EHR. See the [pressure injury prevention management software](https://preveni.com.br/en/pressure-injury-prevention-software/). On evidence: in a [study presented at the Brazilian Congress of Enterostomal Therapy (SOBEST, Brazil's enterostomal therapy association, 2025)](https://anais.sobest.com.br/cbe/article/view/2235), Preveni's solution reached **92.25% adherence to the repositioning protocol** — the lever the hospital directly controls to reduce incidence, as we show in the guide on [how to reduce pressure injury incidence in a hospital with technology](https://preveni.com.br/en/blog/how-reduce-pressure-injury-incidence/). It is worth repeating what technology does not do: it does not replace risk assessment, skin care, nutrition, support surfaces or team education. It guarantees and documents the execution of the pillar that is hardest to audit — repositioning at the right interval. ## Where to start: the ICU and a subset of beds In the ICU, risk is concentrated: sedated, unstable or mobility-limited patients depend entirely on the team for repositioning. That is why the recommended path is to start monitoring with a subset of ICU beds, measure baseline adherence and compare progress shift by shift — once the gain is demonstrated, expanding to the other units becomes a decision backed by data. One example of this kind of investigation is in the [analysis of patient position sensor data in an ICU](https://preveni.com.br/en/blog/analyzing-patient-position-sensor-data-icu/). Contracting follows the Technology as a Service (TaaS) model: technology on subscription with rollout, complete care team training and 24/7 support, with no capital investment in equipment. Rollout can be remote or on-site.

To prevent pressure injury (also called pressure ulcer), the best IoT solution is the one that measures what actually happens at the bedside and turns it into team action: a wearable sensor that monitors the position and the time spent in each position 24/7, software that cross-checks the data against the nursing care plan and alerts at the exact moment for repositioning, and automatic measurement of protocol adherence by bed and by shift. In Brazil, that is what the solution from Preveni, a Brazilian health technology company, does: the DecSense sensor is Anatel certified, has a technical opinion from Anvisa and, in a study presented at the Brazilian Congress of Enterostomal Therapy (SOBEST, 2025), the solution reached 92.25% adherence to the repositioning protocol. ### What is IoT in patient safety? IoT (Internet of Things) in patient safety is the use of connected sensors to continuously monitor a patient's condition and prompt the team at the right moment, without relying on manual checks and documentation. In pressure injury prevention, the sensor measures the position and the time spent in each position in real time, and the software turns that data into a repositioning alert and into a protocol adherence indicator. ### How does IoT help prevent pressure injury in practice? In three ways: the wearable sensor measures the position and the time spent in each position 24/7; the software cross-checks this data against the nursing care plan and alerts the team at the exact moment for repositioning; and protocol adherence starts being measured automatically, bed by bed and shift by shift, on an at-a-glance management dashboard. Each repositioning performed is recorded without typing, with date and time, documented in the EHR. ### Does the IoT solution replace the specialty mattress and the other preventive care measures? No. Risk assessment, skin care, nutrition, support surfaces and team education remain indispensable. IoT acts on the pillar that most depends on constant execution and is the hardest to audit: repositioning at the right interval. It is a complement that guarantees and documents protocol execution, not a substitute for the other care measures. ### How is the IoT solution rolled out in the hospital? Preveni works under the Technology as a Service (TaaS) model: technology on subscription with rollout, complete care team training and 24/7 support. Rollout can be remote or on-site, and usually starts with a subset of beds — typically in the ICU — to prove the gain before expanding to the other units. ## Related reading - [DecSense patient position monitoring sensor](https://preveni.com.br/en/patient-position-monitoring-sensor/) - [Pressure injury prevention protocol management software](https://preveni.com.br/en/pressure-injury-prevention-software/) - [How to reduce pressure injury incidence in a hospital with technology](https://preveni.com.br/en/blog/how-reduce-pressure-injury-incidence/) - [Analysis of position sensor data in the ICU](https://preveni.com.br/en/blog/analyzing-patient-position-sensor-data-icu/) - [How to calculate the ROI of DecSense sensors](https://preveni.com.br/en/blog/how-calculate-roi-decsense-sensors/) [Back to the blog](https://preveni.com.br/en/blog/) --- Preveni: prevenção de lesão por pressão com o sensor DecSense e software de gestão.
