Standard Operating Procedure for Device Accountability, Calibration and Maintenance

Purpose

The purpose of this SOP is to define standardized procedures for the accountability, calibration, and maintenance of devices used in clinical trials. Proper management of devices ensures reliability of data, subject safety, regulatory compliance, and inspection readiness.

Scope

This SOP applies to all investigational devices and equipment used in clinical trials, including diagnostic instruments, monitoring devices, laboratory equipment, and therapeutic devices. It covers device receipt, storage, accountability, calibration, preventive and corrective maintenance, documentation, and disposal.

Responsibilities

• Sponsor: Ensures overall compliance with device accountability and calibration requirements.
• Investigator/Site Staff: Maintain device logs, perform accountability, and ensure timely calibration and maintenance.
• CRA: Verifies device accountability during monitoring visits.
• QA: Reviews calibration and maintenance records for compliance.
• Vendors: Provide calibration certificates and maintenance support.

Accountability

The Principal Investigator is accountable for site-level device accountability, calibration, and maintenance. Sponsor QA is accountable for ensuring oversight and compliance across sites and vendors.

Procedure

1. Device Receipt and Accountability
1.1 Record device receipt in Device Accountability Log (Annexure-1).
1.2 Verify device identification, serial numbers, and condition upon receipt.
1.3 Store devices securely with restricted access.

2. Device Calibration
2.1 Calibrate devices prior to study initiation and at defined intervals.
2.2 Use qualified vendors or accredited laboratories.
2.3 Retain calibration certificates in Calibration Certificate File (Annexure-2).

3. Device Maintenance
3.1 Perform preventive maintenance as per manufacturer’s guidelines.
3.2 Record all maintenance activities in Maintenance Log (Annexure-3).
3.3 Address corrective maintenance promptly when malfunctions occur.

4. Device Use Tracking
4.1 Record device use in Device Use Log (Annexure-4).
4.2 Reconcile device usage with study records.

5. Device Disposal/Return
5.1 At study completion, return or dispose of devices per sponsor/vendor instructions.
5.2 Document in Device Disposal Log (Annexure-5).

Standard Operating Procedure for Laboratory Equipment Calibration and Maintenance

Purpose

The purpose of this SOP is to define processes for calibration and maintenance of laboratory equipment used in clinical trial sample analysis, ensuring that results are accurate, reliable, and reproducible. Proper equipment management is critical for compliance with ICH GCP, GLP, FDA, EMA, CDSCO, and WHO requirements.

Scope

This SOP applies to all laboratory staff, QA personnel, equipment vendors, and service engineers involved in the calibration, preventive maintenance, repair, and verification of laboratory instruments used in clinical trials. It covers balances, pipettes, centrifuges, pH meters, refrigerators, freezers, LC-MS/MS systems, incubators, and other validated instruments.

Responsibilities

• Laboratory Manager: Ensures calibration and maintenance schedules are implemented and followed.
• Analysts/Technicians: Perform daily checks, document readings, and report malfunctions.
• QA: Audits calibration and maintenance records for compliance.
• Vendors/Service Engineers: Perform external calibration and preventive maintenance.
• Sponsor: Ensures laboratory has qualified and compliant equipment for clinical trial testing.

Accountability

The Laboratory Manager is accountable for ensuring that calibration and maintenance activities are performed and documented according to this SOP. QA is accountable for oversight and compliance verification.

Procedure

1. Equipment Qualification
1.1 Perform IQ (Installation Qualification), OQ (Operational Qualification), and PQ (Performance Qualification) before use.
1.2 Maintain qualification certificates in Equipment File.

2. Calibration Schedule
2.1 Prepare and maintain an Equipment Calibration Schedule (Annexure-1).
2.2 Calibrate balances, pipettes, and pH meters quarterly; LC-MS/MS and HPLC systems as per vendor guidance.
2.3 Record calibration details in Calibration Log (Annexure-2).

3. Daily Equipment Checks
3.1 Verify balances with standard weights daily.
3.2 Record refrigerator/freezer temperatures twice daily.
3.3 Document findings in Daily Equipment Check Log (Annexure-3).

4. Preventive Maintenance
4.1 Perform preventive maintenance annually or as per vendor specifications.
4.2 Maintain Maintenance Log (Annexure-4).

5. Calibration and Maintenance Records
5.1 File calibration certificates issued by external vendors.
5.2 Retain records in the Trial Master File (TMF).

6. Out-of-Tolerance Equipment
6.1 If equipment fails calibration, quarantine immediately.
6.2 Record in Out-of-Tolerance Log (Annexure-5).
6.3 Investigate impact on data and initiate CAPA.

7. Vendor Qualification
7.1 Vendors must be qualified through audits and maintain ISO/GLP certifications.
7.2 Document vendor qualification in Vendor Qualification Log (Annexure-6).
