Medical industry is increasingly adopting proton therapy in the oncology field

 


Proton Therapy (PT), a minimally invasive radiation therapy method for the treatment of patients diagnosed with cancer, is now one of the most common cancer treatments. It can be administered in a variety of ways to many different parts of the body depending on the location of the tumor and the extent of the disease. The main advantage of PT is that it is the only therapy that directly targets the tumor itself for the elimination of cancerous growth. In this respect, it is unlike surgery or radiotherapy, which depends on the location and thickness of the targeted tumor for the surgical or radiotherapy treatment.

Patients are normally admitted to a rehabilitation center or a Cancer Treatment Center (CTC), where they stay until the end of the procedure to allow them to recover completely. However, some patients opt to stay in a hospital or an outpatient clinic to undergo proton therapy under the care of a physician. There are certain advantages to this approach including the availability of more personalized care at a lower cost. There are two main methods of delivering the protons into the target area; sub-slab and external beam. The second method is more commonly used because it delivers the radiation waves with greater efficiency, resulting in less pain and minimization of side effects.

Sub-slab proton therapy utilizes smaller trays or containers to deliver the radiation directly into the desired area. The external beam can also be used in combination with a sub-slab to increase the effectiveness of the procedure. The external beam is delivered through a tube, while the internal radiation dose is delivered through plastic tubing. While many patients are able to adjust to the greater level of internal radiation, others may require hospitalization in order to safely adjust to the increased level of outside protons.

The entire process of therapy usually takes two to three hours, however, this does not include the time the trays are inside the patient. The entire procedure is monitored constantly by a team of specialists including oncologists as there is a high chance of patients may exhibit signs of having an increased level of discomfort such as impending pulmonary embolism.

Increasing Initiatives to Digitalize the Healthcare Sector Is Expected To Boost Demand for Electronic Medical Records

Image
  An electronic medical record (EMR) is essentially a systematized collation of individual patient and family health information in an electronic format. This information is then shared across several health care locations. This will save time, money and provide patients with more comprehensive care. Increasing initiatives to digitalize the healthcare sector is expected to boost demand for EMR. For instance, in November 2019, Germany introduced Digital Supply Act to digitalize healthcare. Under the new legislation, doctors will be able to prescribe digital health apps to patients, which can be reimbursed by the country’s statutory health insurance. There are several advantages to using EMR. The main advantage is that you do not need to wait for the paper records to go through the paper processing before you can use them. Another advantage to electronic medical records is that they allow for greater privacy. Electronic health records allow only the doctor to see these...

Ureteroscopes are highly preferred option over traditional ureteroscopy

Image
  Ureteroscopes are instruments that have been designed to allow doctors (including surgeons) to look inside the reproductive organs. This is done by passing a thin, lightweight tube through the cervix and up to the vagina. Once there, the tube makes a turn inside the uterus and exits via the fallopian tubes. The purpose of this excursion is to look for problems in the uterus or ovaries, which can cause infertility or hormonal imbalance in women. They are able to find many problems that other instruments might miss. One of the most common uses for such device is when doctors make the very first ultrasound images of pregnancy. The Ureteroscope is able to detect whether or not the fetus is progressing normally through the maternal birth canal and is able to help determine the health of the mother's uterus. Doctors also use these devices when they make the first "cavity" ultrasound images of a woman's abdominal cavity, looking for problems that could be c...

Pharmacy Benefit Management is an Integral Part of the Medicare System

Image
 Drug costs are rising and contribute altogether to add up to wellbeing consumption around the world. Since 2014, physician recommended drug costs have expanded by 33%. In 2020, worldwide spending on physician endorsed drugs is required to be US$ 1.3 trillion. Expanding drug costs and customer spending on physician endorsed drugs are expanding the interest for the pharmacy benefit management framework. The framework is worked by outsider heads who go about as a connection between drug makers, protection suppliers, and drug specialists. The framework helps with diminishing medication costs by haggling with drug producers and retail drug stores.    The individuals who are tried out different wellbeing plans and those without protection can get the benefit of the pharmacy benefit management framework. The framework gives prescriptions at a lower cost than those accessible at retail drug stores. To decrease rising wellbeing costs, Japan intended to begin evaluating drug cos...
