Tuberculosis is still a rampant problem in the developing world. Doctors are looking for even more advanced ways to test for TB beyond the GeneXpert tests.

Washing hands in between contact with patients is one of the most important things a healthcare worker can do to prevent the spread of disease and reduce the rise of superbugs like MRSA. A new technology is increasing rates of hand washing by displaying, via a sensor in an employee's badge, whether the healthcare provider has washed their hands recently.

A overview of 2014's Fixes columns - connecting the dots between 60 or so ways that people are trying to change the world.

The highest hospital costs come from preventable emergency room visits. A doctor in Camden developed a home visit program which gives better and cheaper care.

A nutrient powder can save anemic children, but the people who could benefit are distrustful. Having local mothers distribute the supplement was successful in Bangladesh.

While critics argue that Naloxone isn't safe for over-the-counter use, some cities have found success distributing Naloxone to community members to help save lives of addicts who overdose. Naloxone can be administered to help those overdosing survive and jump-start the withdrawal process.

Slow test results make it difficult to stop the spread of tuberculosis. Using faster diagnostic technology and driving vans to rural areas in Tanzania, GeneXpert is making progress in treating this curable disease.

Although patients go to hospitals to receive medical care, many Americans will acquire infections that did not already have them. The United States as a whole has made modest progress at reducing the rates of hospital-acquired infections. Spearheading the efforts, the Veterans Affairs Medical Centers have devised anti-MRSA strategies to keep patients safe.

For decades, AIDS has taken the lives of millions of people and infected millions more worldwide. The key to reducing the effect of AIDS, and even potentially curing it, involves treating patients as early as possible after being diagnosed with HIV, before the disease damages organs. San Francisco General Hospital developed the RAPID program for this purpose, with the goal of “Getting to Zero” the number of new infections and deaths.

The health problems of millions of Americans are directly related to patients' failure to follow doctors’ orders. Community health workers are increasingly successful in New York and other American cities – not to substitute for doctors, but to help patients stick to their treatment plans.
