Compliance (or adherence, or concordance) is a medical term that means the degree to which a patient correctly follows medical advice. Most commonly, it refers to medication, or drug compliance, but may also mean use of medical appliances such as compression stockings, chronic wound A chronic wound is a wound that does not heal in an orderly set of stages and in a predictable amount of time the way most wounds do; wounds that do not heal within three months are often considered chronic. Chronic wounds seem to be detained in one or more of the phases of wound healing. For example, chronic wounds often remain in the care, self-directed physiotherapy exercises, or attending counseling or other courses of therapy. The most effective way for a doctor to improve patient compliance is through a positive physician-patient relationship.
Patient compliance is also increase by:[1]
- Patient feeling ill
- Limitations of patients activities due to disease state
- Written instructions for taking medication
- Acute illness
- Simple treatment schedule
- Short time spent in waiting room
- Physician recommending one change at a time
- Benefits of care outweigh costs
- Peer support
Patients may not accurately report back to health care workers because fear of possible embarrassment, being chastised, or seeming to be ungrateful for a doctor's care. Other causes of poor compliance include:[2][1]
- Forgetfulness
- Poor rapport with physician
- Few symptoms
- Chronic illness
- Prescription not collected or not dispensed
- Purpose of treatment not clear
- Perceived lack of effect
- Real or perceived side-effects
- Instructions for administration not clear
- Physical difficulty in complying (e.g. opening medicine containers, handling small tablets, swallowing difficulties, travel to place of treatment)
- Unattractive medicine, size, shape, or taste
- Complicated regimen
- Cost of drugs
- Low health literacy [3]
- Choosing to reserve prescription drugs for recreational use or to sell for profit (prescription drug misuse and abuse Substance abuse, also known as drug abuse, refers to a maladaptive pattern of use of a substance that is not considered dependent. The term "drug abuse" does not exclude dependency, but is otherwise used in a similar manner in nonmedical contexts. The terms have a huge range of definitions related to taking a psychoactive drug or)[4][5]

Terminology
An estimated half of those for whom treatment regimens are prescribed do not follow them as directed.[1] Until recently, this was termed "non-compliance", which was sometimes regarded as meaning that not following the directions for treatment was due to irrational behavior or willful ignoring of instructions. Today, health care professionals more commonly use the terms "adherence" to or "concordance" with a regimen rather than "compliance", because these terms are thought to more accurately reflect the diverse reasons for patients not following treatment directions in part of in full. [6],[3] However, the preferred terminology remains a matter of debate. [7][8] In some cases, concordance is used to refer specifically to paitent adherence to a treatment regimen that is designed collaboratively by the patient and physician, to differentiate it from adherence to a physician only prescribed treatment regimen. [9][10] Despite the ongoing debate, adherence is the preferred term for the World Health Organization [1], The American Pharmacists Association [11], and the U.S. National Institutes of Health Adherence Research Network. [12]
Concordance also refers to a current UK NHS The National Health Service is the name commonly used to refer to the four single-payer publicly funded healthcare systems in the United Kingdom, collectively or individually, although only the health service in England uses the name 'National Health Service' without further qualification. The publicly-funded healthcare organisation in Northern initiative to involve the patient in the treatment process to improve compliance.[13] In this context, the patient is informed about their condition and treatment options. They are involved with the treatment team in the decision as to which course of action to take, and partially responsible for monitoring and reporting back to the team. Compliance with treatment is improved by:
- Only recommending treatments that are effective in circumstances when they are required
- Selecting treatments with lower levels of side effect or fewer concerns for long-term use
- Prescribing the minimum number of different medications, e.g., prescribing a single antibiotic that addresses two concurrent infections (though risking contributing to antibiotic resistant species Antibiotic resistance is a specific type of drug resistance when a microorganism has the ability of withstanding the effects of antibiotics. Antibiotic resistance evolves via natural selection acting upon random mutation, but it can also be engineered by applying an evolutionary stress on a population. Once such a gene is generated, bacteria can development)
- Simplifying dosage regimen by selecting a different drug or using a sustained release Time Release Technology also known as Sustained-release , extended-release (ER, XR, or XL), time-release or timed-release, controlled-release (CR), or continuous-release (CR or Contin) pills are tablets or capsules formulated to dissolve slowly and release a drug over time. The advantages of sustained-release tablets or capsules are that they can preparation that needs fewer doses during the day[14]
- Discussing possible side effects, and whether it is important to continue medication regardless of those effects
- Advice on minimising or coping with side effects, e.g., whether to take a particular drug on an empty stomach or with food
- Developing trust so patients don't fear embarrassment or anger if unable to take a particular drug, allowing the doctor to try a better tolerated alternative
Societal impact
A WHO The World Health Organization is a specialized agency of the United Nations (UN) that acts as a coordinating authority on international public health. Established on April 7, 1948, with headquarters in Geneva, Switzerland, the agency inherited the mandate and resources of its predecessor, the Health Organization, which had been an agency of the study estimates that only 50% of patients suffering from chronic diseases in developed countries follow treatment recommendations.[1] This may affect patient health, and affect the wider society when it causes complications from chronic diseases, formation of resistant infections, or untreated psychiatric illness. Compliance rates during closely monitored studies are usually far higher than in later real-world situations. For example, one study reported a 97% compliance rate at the beginning of treatment with statins Statins are a class of drug used to lower cholesterol levels by inhibiting the enzyme HMG-CoA reductase, which plays a central role in the production of cholesterol in the liver. Increased cholesterol levels have been associated with cardiovascular diseases (CVD), and statins are therefore used in the prevention of these diseases. Randomized, but only about 50% of patients were still compliant after six months.[15]
Compliance issues
Prescription fill rates
While a health care provider visit with a patient may result in a the patient leaving with a prescription for medication, not all patients will fill the prescription at a pharmacy. In the U.S., 20-30% of prescriptions are never filled at the pharmacy.[16][17] There are many reasons patients do not fill prescriptions including the cost of the medication[11][18], doubting the need for medication, or perference for self-care measures other than medication.[19][20] Cost is the most significant barrier to prescription drug adherence. A US nationwide survery of 1,010 adults in 2001 found that 22% chose not to fill prescriptions because of the price, which is similar to the 20-30% overall rate of unfilled presscriptions. [18]
Course completion
Once started, patients seldom follow treatment regimens as directed, and seldom complete the course of treatment.[11][3] Cost and poor understanding of the directions for the treatment (referred to as 'health literacy') are major barriers to completing treatments.[11][3][21] As mentioend previously, the World Health Organization (WHO) has estimates that only 50% of people complete long-term therapy for chronic illnesses as they were prescribed, which puts patient health at risk.[1]
A wide variety of packaging approaches have been proposed to help patients complete prescribed treatments. These approaches include formats that increase the ease of remembering the dosage regimen as well as different labels for increasing patient understanding of directions. [22][23] For example, medications are sometimes packed with reminder systems for the day and/or time of the week to take the medicine.[22] With the objective to support patient adherence to medicinal therapy, a not-for-profit organization (Healthcare Compliance Packaging Council of Europe/HCPC-Europe) [6] was set up between the pharmaceutical industry, the packaging industry and representatives, of European patients organizations. The mission of HCPC-Europe is to assist and to educate the healthcare sector in the improvement of patient compliance through the use of packaging solutions. A variety of packaging solutions have been developed by this collaboration to aid in patient compliance.
The failure to complete treatment regimens as prescribed has significant negative health impacts worldwide.[1] Examples of the rate and consequences of non-compliance for selected medical disorders is as follows:
- Diabetes non-compliance (98% in US) is the principal cause of complications related to diabetes including nerve damage and kidney failure
- Hypertension non-compliance (93% in US, 70% in UK) is the main cause of uncontrolled hypertension-associated heart attack and stroke
- Asthma non-compliance (28-70% worldwide) increase the risk of severe asthma attacks requiring hospitalization
