The provincial metrology weekly inspection meeting for the medical and health system was held. The whole - chain collaboration strengthens the defense line for the accurate measurement of medical equipment
From September 26th to 28th, the provincial metrological weekly inspection meeting for the medical and health system was held at the provincial institute of metrology. As the annual key coordination mechanism in the field of medical metrology, the meeting focused on the core goal of "accurate measurement values of medical equipment", addressed practical problems in verification through industry-wide communication, and laid a solid technical foundation for medical quality and safety.
A participation pattern covering the entire chain
This meeting attracted 95 representatives, covering key roles in the entire process of medical measurement: medical institutions (from provincial top - tier hospitals such as the provincial general hospital and the provincial maternal and child health hospital to grass - roots hospitals in various cities and counties), disease control systems (disease control centers at both provincial and municipal levels), and metrological technical institutions (heads of medical professional departments in municipal metrology institutes). This combination of "users - regulators - technical experts" achieves full - chain coverage from equipment use to metrological supervision, ensuring that the meeting topics meet actual needs.
Weekly inspection situation in 2011: Dual notification of problems and current situations
At the meeting, the results of the annual mandatory verification of medical measuring instruments across the province in 2011 were first reported. A total of 12 types of commonly used instruments, including non-invasive automatic blood pressure monitors, thermometers, biochemical analyzers, and infusion pumps, were verified throughout the year, covering 86 medical institutions. The overall qualification rate was 92.3%. However, there are still common problems at the grass - roots level. Some county and city hospitals failed to send their aging equipment for verification in a timely manner, and the measurement management ledgers of a few institutions were not well - established, resulting in some instruments being "over - used" (for example, a blood pressure monitor that had been used for 5 years in a county hospital had a measurement error of up to 8 mmHg due to non - verification), which directly affected the accuracy of diagnosis. These problems have defined the direction for subsequent rectification work.
2012 Annual Plan: Implement Precise Policies and Strengthen Supervision
In response to the problems exposed in 2011, the weekly inspection plan for 2012 focuses on three key areas:I. Expand coverage: Launch the "mobile metrology vehicle on - site service" for hospitals in remote areas to solve the inconvenience of sending equipment for inspection at the grass - roots level.II. Strengthen key points: Include high - risk instruments such as surgical monitoring equipment and radiotherapy equipment in the "annual mandatory inspection list", and require medical institutions to conduct self - inspections once every six months.III. Optimize processes: Open the "online reservation platform for medical metrology" to enable online handling of the entire process of sending equipment for inspection, paying fees, and picking up items. It is expected to shorten the verification cycle by 30%.The plan aims to promote the improvement of grass - roots metrology management through "targeted efforts".
Regulation learning: Focus on the practical application of common instruments
The meeting focused on organizing the study of the national metrological verification regulation "JJG692 - 2010 Non - invasive Automatic Blood Pressure Monitors". As the most widely used instrument in hospitals and directly related to patient diagnosis, the 2010 version of this regulation has made three major updates compared with the old version: stricter accuracy requirements (the measurement error is tightened from ±5mmHg to ±3mmHg), more detailed calibration methods (new metrological requirements for "ambulatory blood pressure measurement" are added), and a wider scope of application (verification rules for "matching the cuff size with the patient's arm circumference" are clarified). The study adopted the mode of "expert interpretation + case analysis". Combining with the common case in grass - roots units of "measurement errors caused by improper use of cuffs", it enabled the participants to intuitively understand how to implement the regulation. For example, "obese patients need to use large - sized cuffs" and "child patients need to use special pediatric cuffs", so as to avoid measurement errors caused by improper operation.
Three-party communication: Closed-loop connection between technology and demand
The conference builds an interactive platform for "manufacturers - service institutions - users" to promote the direct connection between technology and demand.
Manufacturer: Introduce new products such as intelligent blood pressure monitors and portable multi-parameter calibrators. Emphasize how the "built-in calibration module of the device" reduces the difficulty of daily verification (for example, a certain brand of blood pressure monitor can complete self-check through a mobile phone APP).
Service institution: Share off - site calibration experience of complex equipment (such as MRI and radiotherapy equipment). In response to the problem of the lack of professional personnel at the grass - roots level, propose a "quarterly on - site inspection + remote calibration guidance" plan.
User: Representatives from the hospital put forward requirements based on actual scenarios - "Hope that the metrology institute can add a nighttime inspection and submission channel" and "Require the manufacturer to provide a metrology maintenance manual for the equipment".
During the interaction, the latest technologies (such as the "Laser Doppler Blood Flowmeter Calibration System") and practical skills (such as the "Daily Self - inspection Method for Infusion Pump Flow Calibration") were fully exchanged, achieving a closed - loop of "downward transmission of technical requirements and upward feedback of actual needs".
Core objective: Ensure the "Three Guarantees" throughout the entire process
The ultimate goal of this meeting is to build a closed-loop medical metrology management system through full-chain collaboration.
- The metrology technical institution clarifies the supervision requirements through the "notification + plan".
- Medical institutions improve their equipment management capabilities through learning + communication.
- Manufacturers and service providers connect with actual needs through "interaction".
Ultimately, the "Three Ensurances" will be achieved: ensure accurate measurement values (for example, the error of blood pressure monitors is controlled within ±3 mmHg), ensure effective use (for example, the dose error of radiotherapy equipment does not exceed ±2%), and ensure patient safety (for example, the flow rate error of infusion pumps is less than ±5%). This model of "multi - party linkage and mutual service" will build a "measurement defense line" for medical quality and safety throughout the entire process from equipment production, use to verification. After all, the accuracy of medical equipment is the foundation of diagnosis, the guarantee of treatment, and the bottom - line for patients.
This meeting is not only a work arrangement but also a practice of "collaborative governance" in the field of medical metrology. Through full - chain connection, metrology technology can truly serve medical needs, and accurate measurement values can become the "invisible guardians" of patients' safety.
