Self-management Slides current until 2008
The impact of diabetes • Think of someone you know in your personal or social life who has diabetes • What is your understanding of how they are managing their diabetes? • How do you know? • Do you know… really? • What do they tell you? • What don’t they tell you, if anything? Slides current until 2008
The impact of diabetes • What do you feel is supportive behaviour from close family, friends, or the healthcare professional? • What is not supportive? • If you had diabetes, what would you expect from the people listed above? Slides current until 2008
Why is self-care important? • Not enough healthcare providers for day-to-day management • 24-hours-a-day management is necessary • Better long-term outcomes Bergenstal 1996 Slides current until 2008
Barriers to self-care • Consider barriers to self-care in your culture • Examples: • financial resources • discrimination Slides current until 2008
Barriers to self-care • Lack of knowledge and skills • Lack of support • Lack of resources: • experienced, knowledgeable people • testing equipment, urine tests, meters, access to laboratories • money for medication • Attitude(s) of healthcare professionals • Knowledge of healthcare professionals Slides current until 2008
Self-management abilities The ability to self-manage is enhanced by: • Considering the individual’s need(s) • Teaching skills to carry out medical regimens • Guiding behavioural change • Providing emotional support Von Kroff 1997 Slides current until 2008
Self-care “Medical care for chronic illness is rarely effective in the absence of adequate self-care.” “Self-care and medical care are both enhanced by effective collaboration among chronically ill patients and their families and healthcare providers.” Von Kroff 1997 Slides current until 2008
Self-care • Shared goals • Sustainable working relationships • Mutual understanding of roles and responsibilities • Requisite skills for carrying out their roles Slides current until 2008
Importance of monitoring • Only way to know how diabetes is managed on day-to-day basis • Results in glucose levels closer to target • Teaches how to interpret and act on results • Helps make changes to meals, medication or activities on a daily basis Karter 2001, Jones 2003 Slides current until 2008
Urine glucose testing • Less reliable than blood glucose testing • renal threshold • time delay • colour-dependant • “Better than nothing” • Sometimes more acceptable than pricking finger • Result should always be negative! Slides current until 2008
Urine ketone testing • To determine diabetic ketoacidosis (DKA) primarily in type 1 diabetes: • blood glucose over 14mmol/L (252mg/dl) • during illness • For people with type 2 diabetes that are very sick Slides current until 2008
Blood ketone testing • Blood ketone testing is available in some areas • Especially important in type 1 diabetes • Identifies increases in ketones very early: • DKA prevention • early treatment Slides current until 2008
Blood glucose testing Using meters • Advantages: • reliable • fast • portable • more acceptable and convenient • Disadvantages: • more expensive for some • pricking finger sometimes painful Slides current until 2008
Blood glucose testing Self-monitoring • Best way to learn how nutrition, activity, medical therapy and blood glucose are linked • When regular, it can help adjust doses of oral agents or insulin in relation to food or exercise anticipated in next meal period Slides current until 2008
Blood glucose testing When to monitor • There is no absolute recommendation • Testing times may depend on: • medication regimen • age • stability of blood glucose • personal preference • finances Slides current until 2008
Blood glucose testing Keeping a diary • Explain how to keep a blood glucose diary • Give reasons for keeping a diary • Emphasize importance of entering ALL results • Encourage comments when daily activity is different than usual • Most meters have memories and can be downloaded to computers either at home or in the pharmacy, doctor’s office or diabetes clinic Slides current until 2008
Blood glucose testing Keeping a diary Slides current until 2008
Blood glucose testing Details to be learned • How well did the last medication work? • When did each insulin dose or tablet have the most or least effect? • How did the food eaten affect levels? • What was the benefit of physical activity? Slides current until 2008
Post-meal glucose testing When to test? • Suspected post-meal hyperglycaemia • Monitoring treatment specifically aimed at lowering post-meal glucose • Hypoglycaemia in post-meal state • For information on glycaemic effect of meal Post-meal hyperglycaemia may be associated with increased risk of cardiovascular disease in type 2 diabetes. Ceriello 2004 Slides current until 2008
Common problems • Blood glucose levels do not coincide with how one feels • Not enough blood on strip • Finger prick may be painful • Results do not reflect HbA1c Slides current until 2008
HbA1c • Average reading for last three months, weighted to last four to six weeks • Reliable • No fasting or other preparation needed • Percentage reading • Normal for people without diabetes: <6% (0.06) Slides current until 2008
HbA1c • Target for people with diabetes: <7% (0.07), or lower if achievable without too much hypoglycaemia • If target HbA1c is not met, intensification of the treatment must be considered: • improving lifestyle factors • increasing or adding oral medication • adding insulin to oral medication • intensifying insulin regimens Slides current until 2008
HbA1c Frequency • Every three months or more if treatment changes • Result weighted towards most recent month: • 50% reflects blood glucose in past month • 25% from previous month • 25% from month before that Slides current until 2008
HbA1c Causes of inaccurate results • Haemolytic diseases, such as sickle cell anaemia • High levels of haemoglobin F, S or C • Possible anaemia or recent large blood loss http://www.HbA1cnow.com (18 May 2004) Slides current until 2008
HbA1c Comparison with blood glucose • Mean plasma glucose increase of 2 mmol/L (36 mg/dl) results in 1% HbA1c increase • HbA1c of 5%: mean plasma glucose 5.5 mmol/L (100 mg/dl) • HbA1c of 6%: mean plasma glucose 7.5 mmol/L (135 mg/dl) • Etc Rohlfing 2002 Slides current until 2008
Blood glucose targets 1CDA 2003, 2ADA 2004, 3IDF 2005 Slides current until 2008
Other target values IDF 2005, CDA 2006, ADA 2004 Slides current until 2008
Other target values Slides current until 2008
Summary • Self monitoring of blood glucose improves HbA1c • Regular testing improves self-management • Final goal: delay or prevent complications • Monitoring leads to a positive outcome Slides current until 2008
Review question • Encouraging people with diabetes to perform self-management activities means: • Following their diet, exercising regularly and taking their medications as prescribed • Making informed decisions about their own diabetes care • Allowing us to empower them • Managing their diabetes independently of the healthcare team Slides current until 2008
Review question 2.Which of the following is NOT needed for self-management? • Monitor and respond to symptoms • Adapt decisions and actions to different circumstances and conditions • Know when and how to access help and social support when needed • Study and understand anatomy and physiology of diabetes Slides current until 2008
Review question • How would you help people build their self-efficacy? • Allow them to practice one step at a time • Offer lectures and group discussions in diabetes education classes • Provide demonstrations by experts • Elicit a physiologic response, such as sweaty palms from being nervous Slides current until 2008
Review question • Developing working personal targets for treatment for people with diabetes results in: • Increased stress for healthcare professionals because it is time consuming • Increased chance that the therapeutic strategies developed are implemented • People setting unrealistic goals for their health • Frustration that the healthcare professional is not looking after the person with diabetes Slides current until 2008
Review question • What is the most useful aspect of self blood glucose monitoring? • It helps obtain the information for healthcare professionals to determine treatment • It provides feedback about daily care and self-management activities • It helps individuals correlate symptoms with their blood glucose levels in order to interpret them • It reminds people to watch what they eat Slides current until 2008
