Chronic Illness

Explore the available health information, treatment context, and integrative evidence for Chronic Illness.

Background
  • Illnesses are classified as either acute or chronic. An acute illness lasts for a short period of time and may go away without any intervention, the assistance of medications, and/or surgery. Chronic illness is classified as an illness that recurs or persists for a long period of time and may last for a person's entire life. According to the Centers for Disease Control and Prevention (CDC), chronic diseases are among the most common, costly, and preventable of all health problems. More than 1.7 million people die of a chronic disease each year in the United States. Additionally, approximately 80% of older adults have at least one chronic illness, and at least 50% have at least two. Unfortunately, chronic conditions may lead to pain and disability, which may result in a lower quality of life.
  • The list of chronic illnesses is extensive, but some examples include heart disease, diabetes, cancer, obesity, and AIDS. The healthcare costs of individuals with chronic diseases accounts for over 75 percent of the nation's medical care costs.
  • These illnesses may be improved through lifestyle modifications such as diet and exercise, in addition to medication. Additionally, patients suffering from chronic conditions may need hospice care if they are not expected to live beyond six months. The goal of hospice care is to improve the patient's quality of life by treating the person rather than the disease.
  • Quality of life is a term used to describe different parts of an individual's health and well-being, including physical, mental, psychological, and social components. The goal of health assessment for older adults is to promote well-being.
Risk Factors and Causes
  • Unhealthy diet, lack of exercise, and smoking are risk factors for many chronic diseases. Additionally, increased blood sugar, elevated blood pressure, and obesity may contribute to chronic illness. These are examples of modifiable risk factors, which individuals have the ability to change.
  • As individuals age, their risk of developing a chronic illness increases.
  • Individuals affected by poverty may be more likely to develop a chronic illness since access to healthcare services may be difficult.

  • Disabilities:
    According to the American Geriatrics Society, approximately half of all people who live in nursing homes are at least 85 years old. Additionally, the majority of individuals have some form of disability or impairment with activities of daily living (e.g. walking, bathing).
  • Terminal illness: Individuals who suffer from a terminal illness (an illness for which there is little or no chance of recovery and that will most likely cause death in the immediate future) may receive hospice care to manage pain (palliative care) rather than prolong life. According to the American Geriatrics Society, individuals are eligible for hospice care if they are expected to live six months or less.

Signs and Symptoms
  • Pain can occur in many locations throughout the body. Pain can be constant or intermittent (off and on). Intensity can vary from a dull ache to searing agony. The onset may be sudden and acute, or gradual and chronic (long term), both occurring with or without apparent reason.
  • Chronic pain persists for greater than three months. The term usually describes pain that persists for more than one month beyond the usual course of an illness or injury, pain that recurs off and on for months or years, or pain that is associated with a chronic disorder such as cancer. Usually, chronic pain does not affect the heartbeat, breathing rate, blood pressure, or pupils, but it may result in other problems, such as depression, disturbed sleep, decreased energy, loss of appetite, weight loss, and loss of interest in sexual activity.
  • Many individuals who are being treated for chronic pain may experience a brief, often severe flare-up of pain. This flare-up is called breakthrough pain because it breaks through the regularly scheduled pain medication therapy. Typically, breakthrough pain begins suddenly, lasts up to one hour, and feels much like the individual's chronic pain except it is more severe. Breakthrough pain may differ from one individual to another and is often unpredictable. Improper pain control is the main cause of breakthrough pain.

Diagnosis
  • General: Quality of life describes the overall health and well-being beyond the traditional measures of disease. Additionally, it includes the physical, mental, psychological, and social aspects of an individual's life. However, quality of life may have different meanings to people.
  • Physical function: Activities of daily living,
    such as bathing and eating, play an important part of an individual's quality of life. Unfortunately, patients with disabilities may have difficulties performing activities of daily living. Healthcare professionals may observe various tasks such as walking ability and balance. Patients should wear appropriate footwear (e.g. comfortable flat hard-soled shoes) during the assessment so the doctor may determine whether the problem is physical or related to the shoes.
  • Psychological function: Many older adults affected by a chronic illness may suffer from depression. Individuals suffering from depression are at an increased risk of developing physical disabilities. Doctors should ask patients if they feel sad or depressed so that they may receive appropriate treatment.
  • Social: Doctors should be aware of a patient's social needs. Different factors should be addressed including the availability of family and friends to provide personal support, the need for a caregiver, and the general financial situation of the person.

Complications
  • Daily activities: Chronic diseases may lead to physical and financial limitations. Family members may need to care for patients and help with daily activities, which may ease some of the burden.
  • Depression: Approximately one-third of individuals with a serious medical condition experience symptoms of depression. The illness may affect a person's way of life and ability to function. This may lead to feelings of sadness and helplessness.
  • Stress: Prolonged stress may lead to frustration, anger, hopelessness, and, at times, depression.
Treatment
  • General: It is important for individuals to understand the goals of treatment. The treatment can either be palliative, which helps control symptoms (such as pain), or curative, which may help cure the disease and decrease the chances of it returning. An additional goal of treatment is to increase the quality of life for the individual suffering from the chronic illness.
  • Coping: Support groups provide patients, family, and friends with support and ways of dealing with the emotional situations. Support groups for patients can be located by asking a healthcare provider, such as a doctor or social worker, or searching online.
  • Hospice: Palliative or hospice care is a comprehensive approach to treating the symptoms of illness when a cure is not possible and patients are not expected to live beyond six months. This type of care focuses on the physical, psychological, and spiritual needs of the patient and improving the patient's quality of life by relieving suffering and controlling pain. Healthcare professionals and volunteers provide care for hospice patients in the following settings: home, hospice center, hospital, or skilled nursing facility. Hospice care treats the person rather than the disease, focusing on quality instead of length of life. Additionally, the hospice care team works with family members to provide comfort and support during the grieving process. These services are typically provided for the family for at least thirteen months after the patient's death.
  • Pain medications: For moderate to severe pain, opioid (narcotic) medications may be given. These drugs include morphine (MS Contin®), fentanyl (Duragesic®), hydromorphone (Dilaudid®), and oxycodone (Percocet®, Oxycontin®). Individuals must have a prescription for these medications, and the medications are generally time-released, meaning their effects last more than a few hours. Non-opioids may be used along with opioids for moderate to severe pain. These may include but are not limited to medications used to treat seizures, non-steroidal anti-inflammatory drugs (Motrin®), depression medications, as well as additional drugs that can also work to help with chronic pain. Opioid medications may cause side effects such as drowsiness and constipation. Their use may also cause both physical and psychological dependence in a short length of time. Based on expert opinion, patients should not be afraid to take these medications due to the risk of dependence since untreated extreme pain may lead to many problems such as anxiety, depression, and lack of sleep. However, doctors should emphasize the risk of dependence. If a patient wants to stop taking these medications, the doctor should be involved so that it is done safely. For breakthrough pain (pain that breaks through the regularly scheduled medication therapy), immediate-release opioids may be given, such as oral morphine (Oramorph®) or oxycodone (Roxicodone®). A prescription is required for these medicines. A short-acting opioid, which relieves breakthrough pain quickly, needs to be used with a long-acting opioid for persistent pain. It is important for patients to tell a doctor or pharmacist if they are taking any over-the-counter (OTC) medications, as some OTC medicines may contain acetaminophen (Tylenol®). Some prescription pain medications, such as oxycodone/acetaminophen combination (Percocet®) or hydrocodone/acetaminophen (Lortab®, Vicodin®), may also contain acetaminophen, thereby increasing the potential for acetaminophen induced liver toxicity. Additionally, hydrocodone and oxycodone are not forms of codeine. Based on expert opinion, other non-narcotic drugs will likely be used to help manage the pain.
Prevention
  • Patients may decrease their risk of developing a chronic illness by adopting a healthy lifestyle, avoiding tobacco use, increasing physical activity, achieving optimal weight, improving nutrition, and avoiding sun exposure.
  • Being proactive about one's health and visiting the doctor for regular screenings is extremely important.
  • Regular physical activity reduces the risk for developing many conditions. Exercise has additional benefits including the following: weight control, healthy bones, reducing falls, and reducing anxiety and depression symptoms.
