Introduction


INTRODUCTION/OBJECTIVES

According to the EVM improvement plan 2014; E2 specifies the need to

conduct temperature mapping in all cold and

freezer rooms to support evidence-based

arrangement of vaccines

Identification of temperature deviations

affecting the chosen storage areas during the time of study, so that remedial

action can be taken

Mapping temperature

variations within the selected storage area

Documenting high and low temperature fluctuations caused

by the environmental control systems

operating at the time of the study

Identifying potential airflow

issues that may be the cause of temperature

variations

Measuring temperature

variations at each location within the chosen area, by day

of the week, and time of the day


Recommending safe location for the storage of vaccines in the WICRs

Identifying the best places to locate temperature sensors, for routine monitoring

Making recommendations for any remedial actions needed to overcome the problems identified in the study

EXPECTED OUTPUTS OF

THE MAPPING STUDY


No mapping done!Vaccine exposed to air stream and at risk of freezing

Mapping Protocol


Protocol

• Selection of Electronic data logging monitor (EDLMs); • Designation of Mapping team • Site Survey • Setting acceptance Criteria • Allocating EDLMs to respective locations • Record EDLM, monitoring sensors and thermostat locations • Labelling and programming of the EDLMs • Fixing EDLMS to positions • Conduct the Mapping exercise • Download and Consolidate the data


STEP 1: Selection of Electronic data logging monitor (EDLMs)

• Multiple number of readings• Can be programmed to meet desired criteria• Data can be downloaded from the device into excel page• Accompanied soft ware for analysis

• No display• Sensor can be damaged when handled poorly

• Availability of display • Data can be downloaded from the device

• Already programmed to read daily maximum and minimum values• Limited lifespan• 30 days reading


STEP 2: DESIGNATION OF TEAM MEMBERS

Role Responsibility

Team Lead Coordination

Team Member Programming of loggers

Team Member Labeling and recording of loggers

Team member Placement/removal of loggers

Team Member Monitoring of activity log

Technical lead Downloading / recording of loggers

• Train / orientate team on mapping process

• Share responsibilities to each members

• Record their signatures and initials to track

activities


STEP 3: Site Survey

• Length, width & height dimensions

• Drawing of each area

• Identify locations for the placement of each

EDLMs

• Identify location of cooling components

• Identify location of existing temperature

recording sensors and temperature controlling

sensors


Step 4: Setting acceptance Criteria

• Programme devices to read for 48hours

• Minimum temperature ; 2C Maximum temperature ; 8C

• No of hours to switch between cooling unitStep 5: Designation of EDLMs

Width & Length;• EDLMs should be arranged in a grid fashion along the width & length,

EDLMs locations in every 5-10 meters• Chosen placement area should coincide with locations where vaccines

are actually stored or planned to be stored.

Height;• If the ceiling height is 3.6meters or less; EDLM should be placed

• Floor level, 1.2 meters, 3.0 meters• If the ceiling height is greater than 3.6meters, EDLMs can be arranged

• 0.3m, 1.8m, 3.6m, 5.4m


Step 6; Record EDLM, monitoring sensors and thermostat locations

Step 7; Labelling and programming of the EDLMs


Conduct the Mapping exercise

• Assign members to cold rooms with the required no of EDLMs

• Place all EDLMs in there respective locations (ensure it is placed on the shelves)

• Allow at least 15min for the loggers to adapt to the internal temperature before starting the loggers

• Put an activity log at the door entrance to monitor movement and other associated activities

• After 24hours, switch the cooling unit to the other unit

• After 48hours, remove all data loggers and download the readings.


Conclusion on the overall temperature stability of the area being monitored and the range in fluctuations recorded over the period of study

Location of cold and hot spots in the WICRs

Factors associated to observed temperature variations

Recommendation on the optimum storage location for variant types of sensitive vaccines

Recommendation on optimum location of routine temperature logger placement in the WICRs

EXPECTATIONS AT THE END OF THE STUDY

Insufficient time not allowed for the EDLMs to be conditioned to the ambient temperature before the mapping exercise begins.

Source of potential Errors

An access log was not kept during the study so that any temperature excursions caused by personnel movement can easily be identified. As such Power outages were recorded.

WFCR

Cold spots; 8 Hot spots; 13 Within range: 12Y /10N Analysis: The storage area is not safe for storage of freeze sensitive as we have more of hot

spots. The cold spots reading are also recording higher values Recommendation: There is need to recalibrate the temperature range for the CR (long term). Spacing of vaccines in the hot spots, continuous monitoring of VVMs (short terms) WICR 009; Penta


• Implementation of recommendation • Adoption of protocol• Mapping cascading to zones• Sustaining for the next three years / Routine temperature

review(daily, weekly, monthly, quarterly, yearly).• Results publishing as part of DLHCs operations (end of year)
