As I mentioned in my post last week, Disruptive Women in Health Care is tackling the issue of drug adherence, often referred to as America’s other drug problem. From a health policy standpoint, the issues cross financial, clinical, behavioral, and cultural boundaries.
Over the next two weeks, Disruptive Women and guest bloggers, all experts in their respective field–each representing a different perspective — patient, physician, nurse, pharmacist, researcher, behaviorist, policy analyst, distributor, to name a few–will share their analyses, opinions, and solutions.
At the completion of this series, we will compile an e-book as we did when we tackled the issue of Comparative Effectiveness Research.
THE SCOPE OF THE PROBLEM
A new report, Thinking Outside the Pillbox: A System-wide Approach to Improving Patient Medication Adherence for Chronic Disease, issued by the New England Healthcare Institute (NEHI) found that patients who do not take their medications as prescribed pay a price in poorer health, more frequent hospitalizations and a higher risk of death.
Collectively, noncompliant patients incur up to $290 billion annually in increased medical costs–that’s $290 billion in avoidable medical spending every year, according to the NEHI report.
This is not a new problem, nor is it unique to the US. In 2003, the World Health Organization (WHO) issued a landmark report entitled Adherence to Long-Term Therapies in which it noted:
Adherence to therapies is a primary determinant of treatment success. Poor adherence attenuates optimum clinical benefits and therefore reduces the overall effectiveness of health systems.
“Medicines will not work if you do not take them.” Medicines will not be effective if patients do not follow prescribed treatment, yet in developed countries only 50% of patients who suffer from chronic diseases adhere to treatment recommendations. In developing countries, when taken together with poor access to health care, lack of appropriate diagnosis and limited access to medicines, poor adherence is threatening to render futile any effort to tackle chronic conditions, such as diabetes, depression and HIV/AIDS.
This report is based on an exhaustive review of the published literature on the definitions, measurements, epidemiology, economics and interventions applied to nine chronic conditions and their risk factors. These are asthma, cancer (palliative care), depression, diabetes, epilepsy, HIV/AIDS, hypertension, tobacco smoking and tuberculosis.
In the intervening years since the WHO issued its report, adherence has become more problematic. Numerous reports highlight the ongoing challenges, which are especially critical in the mental health arena.
A study in the American Journal of Psychiatry found that close to 60% of schizophrenics who were prescribed anti-psychotic drugs did not take the medication as prescribed by their physicians. “We looked at adherence to anti-psychotic medication because they form the backbone of treatment for schizophrenics,” said Dr. Dilip Jesete, co-author of the study. “These medications are good, but only work when taken properly.”
The study found that psychiatric hospitalizations were higher for people who did not take their medication as prescribed.
When schizophrenics, a disease which affects over 2 million Americans, do not take their medication, they are at risk for dying by suicide. Four out of ten people who suffer from schizophrenia attempt suicide and one in ten die by suicide.
SOLUTIONS
Despite the complexity of adherence related challenges, a number of promising solutions, innovative responses and well-researched efforts are underway. Many of these will be described in greater detail in our Drug Adherence series.
Some of these include:
- Text message alerts to remind patients
- Greater use of health care teams
- Integration of health information technology
- Creation of online and offline medication management systems, reminders
- Health e-games
- Insurance reforms
- Public awareness campaigns
- Patient education
- Mobile phone applications
- Research in gender-based barriers
We look forward to your comments and input as we shed light on this critical policy issue.
