Cystic fibrosis-related diabetes (CFRD) presents unique challenges that distinguish it from type 1 and type 2 diabetes. Individuals with CF experience progressive scarring and damage to the pancreas, which impairs both insulin production and the release of digestive enzymes. Over time, the insulin-producing beta cells become compromised, leading to a form of diabetes that combines elements of insulin deficiency and insulin resistance. Unlike typical diabetes, CFRD often develops gradually, and its symptoms—such as unexplained weight loss, fatigue, and frequent respiratory infections—can overlap with CF itself, making detection more difficult. Annual oral glucose tolerance tests are recommended for all CF patients over age 10, yet many families remain unprepared for the acute emergencies that can arise when blood glucose swings out of control.

During periods of illness, infection, or high-dose corticosteroid treatment, the body releases stress hormones that raise blood sugar levels dramatically. At the same time, decreased appetite or vomiting can cause rapid drops in glucose, especially if insulin doses are not adjusted. This volatility means that every person with CFRD and their care network must be ready to respond to both hypoglycemia and diabetic ketoacidosis (DKA). An emergency action plan transforms that readiness into a reliable, repeatable sequence of steps that anyone—from a parent to a substitute teacher—can follow under pressure.

Why a Dedicated Emergency Action Plan Matters

Standard diabetes emergency protocols often fail to account for the respiratory and nutritional complications unique to CF. For instance, a child with CFRD who develops hypoglycemia may also be battling a pulmonary exacerbation, meaning that administering glucose without addressing oxygen needs could worsen the overall crisis. Similarly, the signs of DKA—nausea, abdominal pain, rapid breathing—can be misinterpreted as a CF gastrointestinal issue or a lung infection flare, delaying life-saving insulin therapy. A CFRD-specific emergency action plan bridges this gap by integrating diabetes management with CF care, ensuring that responders consider the whole picture rather than treating each condition in isolation.

Beyond the medical rationale, these plans provide peace of mind. When teachers, coaches, babysitters, and extended family members carry a concise, laminated card or have instant digital access to the plan, the individual with CFRD can participate more freely in school, sports, and social activities. The plan reduces hesitation and guesswork, empowering non-medical caregivers to act with confidence during the critical first minutes of an emergency.

Core Components of the Emergency Action Plan

Every CFRD emergency action plan should be individualized, reviewed by the endocrinologist and CF care team, and distributed to everyone in the patient's support network. The following sections provide a framework for building a comprehensive plan.

Patient Identification and Medical Information

The plan must prominently state the patient’s full name, date of birth, emergency medical ID number (if applicable), and the specific diagnosis: "Cystic fibrosis-related diabetes (CFRD)." It should note any other significant CF complications, such as pancreatic insufficiency, liver disease, or a history of nontuberculous mycobacteria infection, that could influence treatment decisions. Encourage the use of a medical ID bracelet or necklace that reads "CFRD" or "CF-Related Diabetes" along with an emergency contact number.

Emergency Contact List

Include direct phone numbers for:

  • Primary CF care team (clinic nurse, dietitian, and physician).
  • Endocrinologist who manages the CFRD.
  • Local emergency medical services (EMS) and the nearest hospital emergency department.
  • Parents or legal guardians (list work, cell, and home numbers).
  • Backup contacts (relative, neighbor, or friend) if parents cannot be reached.

Recognizing Hypoglycemia (Low Blood Sugar)

Hypoglycemia is the most frequent acute complication in CFRD, especially during or after exercise, missed meals, or aggressive insulin dosing. The plan should list common symptoms, noting that some may be blunted in individuals with CF who have autonomic neuropathy. Key signs include:

  • Shaking or tremors.
  • Sweating or clammy skin.
  • Sudden hunger, nausea, or stomachache.
  • Irritability, confusion, or drowsiness.
  • Blurry vision or difficulty speaking.
  • Seizures or loss of consciousness (severe hypoglycemia).

Provide clear instructions for confirming low blood glucose with a meter or continuous glucose monitor (CGM) if the patient is conscious and able to cooperate. If a reading is not immediately available but symptoms are present, treat for hypoglycemia first.

Immediate Treatment Steps for Hypoglycemia

  1. Conscious and able to swallow: Administer 15 grams of fast-acting carbohydrate. Examples include 4 glucose tablets, 4 ounces of fruit juice or regular soda, 1 tablespoon of honey or sugar, or 8 ounces of milk. Wait 15 minutes, recheck blood glucose, and repeat if still low. Once the glucose is above 70 mg/dL, follow with a small snack containing protein and fat if the next meal is more than an hour away.
  2. Unconscious, seizing, or unable to swallow: Do NOT give anything by mouth. Place the person on their side to protect the airway. Administer glucagon via injection, auto-injector, or nasal powder per the prescribed dose. Call 911 immediately. Notify parents and the CF team after the emergency is under control.

Recognizing Hyperglycemia and Diabetic Ketoacidosis (DKA)

Hyperglycemia in CFRD often develops silently during illness. DKA is a medical emergency that can progress rapidly in the presence of infection, dehydration, or missed insulin doses. The plan should highlight these warning signs:

  • Excessive thirst and frequent urination.
  • Dry mouth, flushed skin, or warm skin that does not sweat.
  • Nausea, vomiting, or abdominal pain (may mimic CF bowel obstruction).
  • Rapid deep breathing (Kussmaul breathing) or shortness of breath.
  • Fruity, acetone-like odor on the breath.
  • Confusion, extreme fatigue, or unconsciousness.

Immediate Steps for Suspected DKA

  • Check blood glucose and urine ketones if a ketone meter is available. Blood ketone levels above 0.6 mmol/L with hyperglycemia require urgent care.
  • Do not exercise—physical activity can worsen ketosis.
  • Encourage drinking water or sugar-free fluids to combat dehydration, but do not force if vomiting is present.
  • Call the CF care team or endocrinologist immediately for guidance on insulin adjustment. In many cases, the patient will need an extra dose of rapid-acting insulin along with close monitoring.
  • If vomiting persists, breathing is labored, or consciousness is altered, call 911 and state that the person has cystic fibrosis-related diabetes and may be in DKA.

Medication and Supply Management

The emergency plan should include a detailed medication list with generic and brand names, doses, routes of administration, and timing. For insulin, specify the type (e.g., insulin lispro, insulin glargine) and the dosing schedule. Note any non-insulin medications such as metformin or GLP-1 receptor agonists if prescribed, and include CF-specific drugs like pancreatic enzymes, fat-soluble vitamins, and inhaled antibiotics.

Supply checklist that should travel with the patient at all times:

  • Blood glucose meter or CGM receiver/smartphone with testing supplies.
  • Urine or blood ketone test strips.
  • Fast-acting glucose source (glucose tablets, gel, or juice box).
  • Glucagon emergency kit (injectable or nasal spray).
  • Insulin pen or syringe with spare pen needles and a sharps container.
  • Cooler pack for insulin storage if temperatures exceed 86°F (30°C).
  • Written copy of the emergency action plan (laminated or sealed in a plastic sleeve).
  • Medical ID bracelet or necklace.

Training Caregivers and School Personnel

Creating the plan is only the first step. Without regular training and practice, even the best document will gather dust in a backpack. Schedule a session at the start of each school year, after any change in insulin regimen, and whenever a new caregiver joins the team. Ideally, the training should include:

  • A review of the symptoms and treatment steps for hypoglycemia and DKA.
  • Hands-on practice with the glucose meter, glucagon device, and insulin administration (using saline in a training pen).
  • A walk-through of the emergency plan itself, emphasizing where each supply is stored and how to contact the parents or CF team.
  • A question-and-answer period to address specific fears or misconceptions about CFRD.

Many CF centers offer a "CFRD School Toolkit" that includes a sample plan, video demonstrations, and letter templates for the school nurse. The CF Foundation also provides resources on managing CFRD at school and in the community.

Simulated Emergency Drills

Conducting a yearly drill can expose gaps in the plan before a real crisis occurs. For example, a parent might ask a teacher to simulate a hypoglycemic event while the school nurse is out of the building. Does the substitute know where the glucagon is kept? Can the front desk reach the parents within two minutes? The drill creates muscle memory and reduces panic. Afterward, debrief with everyone involved and update the plan as needed.

Special Considerations for CFRD Emergencies

Illness Management (Sick-Day Rules)

Illness—whether a common cold, influenza, or a CF pulmonary exacerbation—destabilizes blood glucose control. The plan should include a sick-day protocol that covers:

  • How often to monitor blood glucose and ketones (every 2–4 hours during illness).
  • Insulin dose adjustments based on blood glucose trends and ketone levels. Many patients need higher insulin doses during infection, but the plan must specify when to call the doctor rather than self-adjusting.
  • Hydration and calorie goals to prevent dehydration and weight loss. If the patient cannot tolerate solid food, suggest clear liquids with sugar (apple juice, Pedialyte) alternating with sugar-free options.
  • When to seek emergency care: vomiting more than twice in 4 hours, inability to keep down fluids, moderate or large urine ketones, or any sign of DKA.

The CF care team should provide written sick-day guidelines that align with the patient’s current insulin pump or multiple daily injection regimen. Post the guidelines next to the home phone and include them in the emergency plan binder.

Exercise and Physical Activity

Exercise is beneficial for lung function and overall health in CF, but it can cause both hypoglycemia (during or immediately after activity) and delayed hypoglycemia (4–12 hours later). The emergency plan should address exercise precautions:

  • Check blood glucose before, during (if activity lasts longer than 60 minutes), and after exercise.
  • If blood glucose is below 100 mg/dL before exercise, eat a 15–30 gram carbohydrate snack without insulin coverage.
  • Reduce rapid-acting insulin doses before and after exercise as advised by the endocrinologist.
  • Keep fast-acting carbohydrates and water readily available during sports and recess.
  • Be aware of symptoms of hypoglycemia that may mimic exercise exhaustion (trembling, weakness, confusion).

School and Childcare Settings

Under U.S. federal law (Section 504 of the Rehabilitation Act and the Americans with Disabilities Act), children with CFRD are entitled to accommodations that ensure their safety and equal access to education. The emergency action plan should be attached to the child’s individualized healthcare plan (IHP) or 504 plan. Specific accommodations may include:

  • Permission to carry diabetes supplies and snacks in the classroom.
  • Unrestricted access to water and bathroom breaks.
  • A designated staff member trained in glucagon administration during every school activity, including field trips, after-school programs, and bus rides.
  • Excused absences for medical appointments without penalty.

The school nurse or health aide should retain a signed copy of the physician-approved emergency plan and review it annually. Many school districts also require a "Diabetes Medical Management Plan" signed by the doctor, which can be combined with the CFRD emergency action plan.

Travel and Away-from-Home Events

Whether the patient is attending a CF education day camp, a family vacation, or an overnight college visit, the emergency plan must travel with them. Prepare a travel kit that includes:

  • Two weeks’ supply of insulin and glucagon (packed in carry-on luggage if flying).
  • Extra pump supplies, batteries, and backup syringes if using an insulin pump.
  • A travel letter from the doctor explaining the need for all medications, syringes, and glucose monitoring devices through airport security.
  • Emergency contacts in the destination city (nearest CF center and endocrinologist).
  • Copies of the emergency action plan in the local language if traveling abroad.

Check with the airline or travel company about refrigeration for insulin and the availability of medical assistance on board. For long-haul flights, plan for frequent blood glucose checks and adjustments for time zone changes. The CF Foundation’s international directory can help identify CF care centers in other countries.

Reviewing and Updating the Plan

A static emergency plan quickly becomes obsolete. Schedule a formal review every six months or after any of these events:

  • Change in insulin type, dose, or delivery system (e.g., starting a pump).
  • Hospitalization for DKA or severe hypoglycemia.
  • New CF complication (e.g., liver disease, lung transplant evaluation).
  • Change in school, caregiver, or residence.
  • Significant weight change or growth in children.

During the review, contact the CF care team and endocrinologist to confirm that the emergency instructions still match current best practices. Ask each caregiver whether they have any questions or if they feel confident using the glucagon device. Replace expired supplies—especially glucagon and test strips—and update phone numbers immediately.

Building a Culture of Preparedness

An emergency action plan is more than a document; it is a commitment to vigilance and communication. Families who talk openly about CFRD with neighbors, coaches, and extended family members reduce stigma and build a safety net. Consider hosting an informal "CFRD 101" session at the start of each school year, inviting teachers, bus drivers, and the parents of close friends. Hand out a simplified one-page version of the plan that fits in a wallet or phone case. Encourage everyone to ask questions now rather than in the middle of a crisis.

By integrating these strategies into a living, practiced emergency action plan, individuals with cystic fibrosis and diabetes gain the freedom to live fully while knowing that their community is ready to support them. For more detailed guidance on building a CFRD-specific plan, consult the Cystic Fibrosis Foundation’s CFRD resources and the American Diabetes Association emergency planning tools. These organizations offer downloadable templates, training videos, and provider directories that can help tailor the plan to each patient’s unique needs.
