iCGM certified — suitable for pump dosing decisions
Libre 3
7.9%
Excellent accuracy; real-time 1-min readings
Libre 2
9.3%
Good; sufficient for most clinical decisions
Guardian 4
8.8%
Reliable within 780G system
MARD = Mean Absolute Relative Difference. Lower = more accurate. <10% is clinically acceptable for non-adjunctive use. In critical care, always confirm CGM readings with fingerprick before insulin dosing.
Factors Reducing CGM Accuracy
Rapidly changing glucose (lag up to 5–15 min between blood and interstitial)
Acetaminophen/paracetamol — can falsely elevate Libre readings
Hydroxyurea (haematological treatments) — affects some sensors
Compression (lying on sensor at night)
Extreme temperature (GCC: sensor in direct sunlight or prolonged heat)
Each 5% increase in TIR (70–180) corresponds to approximately 0.2% decrease in HbA1c. TIR is now endorsed as a primary endpoint alongside HbA1c in clinical trials.
📊 Ambulatory Glucose Profile (AGP) Interpretation
Median line (50th percentile): Typical day glucose pattern — look for post-meal spikes and overnight patterns
High Alert 250–300 mg/dL — individualise based on HbA1c target
Rise/Fall Rate 2–3 mg/dL/min alerts — useful for active patients
Alarm Fatigue Management
Start with conservative thresholds, tighten over 4–6 weeks
Nighttime: lower high alarm to reduce sleep disruption initially
Do NOT silence urgent low alarm
Review alarm frequency at every clinic visit
Coach patients on "snooze" vs "dismiss" distinction
📱 Libre: Scanning Frequency Education
Libre 1 stores only 8 hours of data. If scanned less frequently, data is lost permanently. Educate patients to scan at least every 8 hours — ideally before meals and at bedtime.
Libre 2/3 (real-time): continuous Bluetooth transmission — scanning still encouraged to see trend arrows
Scan before meals, before driving, before exercise, before sleep
Each scan shows current glucose + 8-hour history + trend arrow
Trend arrow interpretation: ↑↑ rising fast (>2 mg/dL/min); ↓↓ falling fast
🧮 Interactive Time-in-Range Analyser
Enter percentage values from your patient's CGM report to generate a colour-coded TIR breakdown with clinical interpretation.
Rule of 1800: ISF (mg/dL) = 1800 ÷ TDD. Rule of 500: ICR = 500 ÷ TDD. These are starting estimates only — always individualise based on CGM data over 1–2 weeks.
🩹 Infusion Site Care
Rotation Protocol
Rotate in a structured grid pattern — divide abdomen into quadrants, use each site 1 week apart minimum
Upper buttock, lateral thigh, upper arm (pod pumps) acceptable alternatives
Tubed pumps (Medtronic, Tandem): every 2–3 days; change reservoir and infusion set together
Omnipod: pod lasts 72 hours (3 days) — auto-deactivation alarm after 80 hours
Never exceed 3 days — site degrades, insulin absorption unpredictable
Signs of Site Problem (Educate Patient)
Unexplained hyperglycaemia despite boluses (most common sign of occlusion)
Pain or burning at infusion site
Insulin leakage around cannula
Blood in cannula or tubing
Pump occlusion alarm
If unexplained hyperglycaemia >14 mmol/L (250 mg/dL) persists >2 hours with no CGM upward trend, assume occlusion. Give correction by injection (NOT pump bolus). Change entire infusion set AND site. Check for ketones.
⚠️ Pump Cessation: MRI and Surgery
MRI: ALL pumps must be removed before MRI — magnet will damage pump electronics
CT/X-ray: Pump can remain on but document pump presence for image interpretation
Surgery: Discuss with anaesthetic team — general preference is to remove pump in major surgery; continue in minor procedures with surgical team agreement
If pump removed: calculate equivalent MDI doses (50% TDD as glargine; 50% as bolus doses)
Pump off >1 hour: risk of ketoacidosis in T1DM — insulin depot absent
DKA risk is significantly higher with pump users vs MDI in the event of pump failure, occlusion or discontinuation without insulin supplementation. Pumps use rapid-acting insulin only — no depot.

Hybrid Closed Loop (HCL) Systems
Artificial pancreas technology available in GCC — auto-mode operation and nursing education
HCL systems automate basal insulin delivery based on CGM readings — but they are HYBRID: meal boluses must still be announced manually. This is the most important patient education point.

⚡ Auto-Mode Function
How Auto-Mode Works
CGM reading transmitted every 5 minutes to pump
Algorithm predicts glucose 30 min ahead
Adjusts basal rate up (microbolus) or down (reduce/suspend)
Target glucose maintained within defined range
Adapts to individual patterns over days–weeks
What Auto-Mode CANNOT Do
Deliver full meal bolus automatically
Compensate for uncounted carbohydrates
Work without a functioning CGM sensor
Prevent all hypoglycaemia (exercise is challenging)
Self-diagnose occlusion without alarms
🛡️ Safety Features: Suspend Functions
Suspend Before Low (Predictive LGS)
Suspends insulin delivery when algorithm predicts glucose will fall below threshold (typically 70 mg/dL) within 30 minutes. Resumes automatically when glucose stabilises.
Suspend on Low (LGS)
Suspends insulin immediately when CGM falls below threshold (typically 60–70 mg/dL). Two-hour maximum suspend. Must treat hypoglycaemia actively — do not rely on suspend alone.
🍽️ Meal Announcement and Manual Bolus
Bolus BEFORE meals — not after. Post-meal bolusing significantly worsens post-meal TIR
Enter carbohydrate count or use "easy bolus" (pre-set meal sizes) depending on system
Bolus wizard calculates dose based on ICR, ISF, IOB and current CGM
System will auto-correct residual hyperglycaemia over subsequent hours — but this should not replace meal bolus
Activity Mode
Most HCL systems offer an activity/exercise mode: raises target glucose (e.g. to 150 mg/dL) to reduce hypo risk during exercise
Activate 60–90 minutes BEFORE exercise (predictive lag)
Infusion site occlusion (pump suspends, exits auto)
Patient manually overrides settings too frequently
Algorithm has insufficient data (<24 hr on new sensor)
Troubleshooting Steps for Nurses
Confirm CGM sensor status — active, transmitting, no errors
Check pump screen for specific alarm code
Verify infusion site — change if >2 days old or glucose unexpectedly elevated
Check insulin reservoir volume — refill if <20 units remaining
Review auto-mode exit reason in pump history log
If repeated dropouts: consider reset to manual mode temporarily, review with diabetes technology team
Patients must have a "sick day" plan for auto-mode dropout. They need to know their manual basal rate and how to calculate correction boluses — do NOT initiate HCL without this education complete.
📋 HCL Initiation Nursing Education Checklist
Hospital Management of Diabetes Technology
Policies for inpatient CGM and pump use, transitions to IV insulin, MRI safety
Never assume a patient's pump or CGM is functioning correctly in hospital. Equipment may have been damaged, sensors may have expired, and stress hyperglycaemia alters glycaemic patterns significantly.
🏥 Insulin Pump Continuation in Hospital
Pump MAY Continue if:
Patient is alert and able to self-manage (able to calculate and deliver boluses)
Pump and CGM are functioning normally
Not going for MRI or surgery requiring general anaesthesia
Not in DKA
Endocrinology/diabetes team has assessed and documented
"Pump-aware" nursing staff are caring for patient or patient is self-managing under supervision
Pump MUST be Discontinued if:
Patient is unconscious, confused or nil by mouth (nil orally)
DKA — transition to IV insulin
Pump malfunction or inaccessible programming
MRI procedure (remove ALL diabetes devices)
Major surgery with general anaesthesia
Patient unable or unwilling to manage self
ICU admission — standardise to IV insulin protocol
👩⚕️ Pump-Aware vs Pump-Naive Nursing Staff
Competency Level
Definition
Actions Permitted
Pump-Naive
No formal pump training
Can observe pump; call pump-aware colleague or diabetes team for any pump decision; document pump in place
Pump-Aware
Completed basic pump training
Can assess pump site, read pump screen, respond to alarms, discontinue pump safely if needed
Pump-Competent
Full diabetes technology training
Can programme pump, adjust rates under protocol, initiate/discontinue pump, troubleshoot alarms
Document pump model, current settings and who is responsible for pump management at every ward handover. Add to nursing care plan.
💊 Transition from Pump to IV Insulin
Indications for Transition
DKA (pump failure or suspected occlusion as trigger)
Major surgery / ICU admission
Peri-operative fasting
Pump unavailability
Transition Protocol (General)
Record pump TDD from pump history
Remove infusion set and disconnect pump
Calculate IV insulin rate: TDD ÷ 24 = hourly units (starting estimate for DKA protocol)
Initiate DKA protocol if pH <7.3 or bicarbonate <15
Hourly fingerprick (NOT CGM) for IV insulin titration — CGM less accurate in critical care
Ensure separate IV dextrose if glucose falling too fast
When recommencing pump post-DKA: ensure trigger (occlusion / ketones / sick day) is resolved. Restart pump only when patient is eating, fully alert, ketones <0.6 mmol/L, and IV insulin has been discontinued 30–60 minutes AFTER first subcutaneous bolus.
📡 CGM Accuracy Limitations in Hospital
CGM is NOT approved for IV insulin dosing decisions in critical care
Paracetamol/acetaminophen IV → falsely elevated Libre readings
CGM trend data may still be clinically useful (is glucose rising or falling?) but absolute values must be confirmed with fingerprick
Policy: Confirm all CGM values with fingerprick capillary blood glucose BEFORE making ANY insulin dosing decision in a hospitalised patient. Document both values.
🧲 MRI/CT Considerations
MRI — Remove ALL:
Insulin pump (tubed and patch)
CGM sensor and transmitter
Libre sensor
Flash / real-time CGM readers
Note: Do NOT re-insert removed sensor after MRI — replace with new sensor
CT / X-ray — Consider:
Pump can remain on during CT (non-magnetic)
Metal artefact may appear on imaging — document device location
CGM sensor can remain during CT/X-ray
Remove for interventional radiology if high-dose X-ray exposure to sensor area
🔄 Post-Operative Pump Restart Protocol
Confirm patient is alert, eating and tolerating oral intake
Ketones <0.6 mmol/L and blood glucose <15 mmol/L (270 mg/dL)
Discontinue IV insulin (if running) — wait 30–60 minutes after disconnecting IV
Prime a new infusion set with fresh insulin and new site
Restart at pre-operative pump settings (document source of settings)
Restart CGM sensor — new sensor if old sensor >9 days (Dexcom) or >13 days (Libre)
Initial fingerprick BG every 2 hours for first 6 hours after pump restart
Endocrine team review before discharge

SQUH active in diabetes technology research
Libre 2 is one of the most cost-effective CGM options in GCC (~$60–80 USD per sensor). For patients who cannot afford continuous CGM, encourage scanning frequency optimisation and professional CGM review every 3–6 months.
🌙 Ramadan and Diabetes Technology
Approximately 50–80% of Muslims with T1DM and T2DM fast during Ramadan despite medical advice. Diabetes technology significantly improves safety and glucose management during fasting.
CGM in Ramadan
Libre/Dexcom: transformative for Ramadan — continuous glucose visibility during long fasting hours (16–18 hr in GCC summer)
Low alarms protect against hypoglycaemia during non-eating hours
High alarms detect post-Iftar hyperglycaemia spikes
Pre-Suhoor scan guides pre-dawn dose adjustments
Remove sensor for Wudu? — No. CGM sensors are waterproof; Wudu does not require removal. Fatwa guidance: medical device does not invalidate fast
Insulin Pump in Ramadan
Pump advantage: basal rate can be reduced 20–30% during fasting hours
ICR adjustments: Iftar meals often large and high-carb — dual wave bolus ideal
Suhoor: small bolus with standard or extended wave for slow digestion
Apply adhesive to skin, not sensor — avoid blocking sensor membrane
Patch pump (Omnipod) pods: heat + sweat = higher pod failure rate; use medical tape overpatch
Shower after exercise before new sensor application — clean dry skin essential
CGM transmitters: waterproof rated but prolonged saltwater (sea/pool) exposure may affect seal
🕌 Prayer Positions and Device Placement
Sujood (prostration): Pressure on abdomen — Libre arm placement may be preferable for comfortable prayer
CGM on upper outer arm: least affected by prayer positions
Tubed pump: tuck pump in pocket, waistband pouch, or under clothing during prayer
Omnipod: no tubing — minimal prayer impact; abdominal placement well tolerated
Medically unnecessary removal of CGM/pump for prayer is not required; religious scholars have confirmed medical devices do not invalidate prayer or fast
Advise checking glucose before Fajr (pre-dawn) and before/after long prayer sessions in Ramadan
