How Does the US Health System Work?
Healthcare in the United States is organized in a complex bureaucracy. While in the rest of the world healthcare facilities are owned mostly by governments or by private sector businesses, in the US a large share of hospitals and clinics are owned by private non-profit organizations.
Yet, the United States is the country that has the highest healthcare expenditures in the world. While these expenditures are covered in a large share by public payers as by Federal institutions, or State and local governments, they can also be covered by private insurance and individual payments.
At the same time, unlike most developed nations, the US health system does not provide health care to its entire population. As there is no single nationwide system of health insurance, the United States primarily relies on employers who voluntarily provide health insurance coverage to their employees and dependents.
In addition, the government has programs that tend to cover healthcare expenses for the fragile parts of the society as the elderly, disabled and the poor. These programs differ from one another, and all have a specific kind of people that are subject to.
Getting health insurance in the US is not an easy thing. Someone may think that once you have money everything is easy peasy, but in fact things are a bit more complicated. One must be very careful and look out to pick the right insurance.
Health Insurance in the United States for non-Citizens
The United States government does not provide health insurance for all its people, and health insurance is not obligatory for those living in the US. It is optional, but highly recommended and necessary since health services are very costly, more than in any other country anywhere across the globe.
There are two types of health insurances in the US, private and public. Most people use a combination of both. The US public health insurances are: Medicare, Medicaid, and Children’s Health Insurance Program.

The US has the most expensive healthcare in the world. That’s why getting adequate health insurance coverage comes highly recommended.
Medicare
Medicare is a national health insurance program that dates back to 1966. It provides health insurance for US nationals older than 65 years old, but also for younger people with end stage renal disease, ALS, and some other disabilities.
Data shows that in 2018, Medicare provided almost 60 million individuals with healthcare in the US, over 51 million of which were older than 65.
The Medicare program is divided into four parts:
Part A – which covers hospitals, skilled nursing and hospice services.
Part B – covers outpatient services, including some providers’ services while inpatient at a hospital, outpatient hospital charges
Part C – is an alternative called Managed Medicare, which permits patients to select health plans with at least the same service coverage as Part A and B, often the benefits of Part D, and an annual out of pocket spend limit which A and B lack. To sign in this part, one must sign in Part A and B fist.
Part D – covers mostly self-administered prescription drugs.
Medicaid
Medicaid is a federal and state program that helps people with limited income and resources to cover medical costs, while covering benefits normally not covered by Medicare, as nursing home care and personal care services.
It is the largest source of funding for medical and health-related services for people with low income in the United States. Data shows that the US provided health insurance to 71 million people with low income or disabilities, which is 23% of the total of the US’ population.
Children’s Health Insurance Program
Formerly known as the State Children’s Health Insurance Program (SCHIP), this is a program that covers with health insurance children of families with modest income, that are not low enough to qualify for Medicaid.
The West African Society of Parenteral & Enteral Nutrition (WASPEN) has called on President Bola Ahmed Tinubu to make clinical malnutrition a national healthcare priority, warning that the crisis is growing but remains largely overlooked in Nigeria’s healthcare system.
WASPEN’s Founder and President, Dr. Teresa Pounds, made this appeal on Monday during a press conference ahead of the 2025 WASPEN Clinical Nutrition Conference, scheduled for June 17–19 in collaboration with the National Hospital Abuja.
Themed “Bridging the Gap: Integrating Hospital and Community Malnutrition Care in Developing Countries,” the event aims to foster solutions for hospital and community malnutrition.
Describing malnutrition as “the skeleton in the hospital’s closet,” Dr. Pounds emphasised the need for urgent awareness, policy reform, and collaboration among healthcare stakeholders to ensure effective hospital nutrition programs.
“Many patients in Nigerian hospitals suffer from inadequate nutritional support, leading to prolonged hospital stays, increased complications, and higher mortality rates. This issue must be addressed at the highest level,” she stated.
The press conference was attended by the management of Genrith Pharmaceuticals Limited, a major partner, led by its CEO, Chief Emmanuel Umenwa.
Call for National Clinical Nutrition Policy
Dr. Pounds, a U.S.-based specialist in critical care nutrition and a board-certified nutrition support pharmacist, urged the government to implement a national policy framework to support specialised clinical nutrition interventions. She stressed the importance of integrating mandatory nutrition screening and intervention into all healthcare facilities.
She also called on the Federal and State Ministries of Health to expand and enforce standardised clinical nutrition policies, ensure hospitals conduct structured nutrition screening for all patients, makes medical nutrition therapy accessible and affordable, and support research and local production of specialised nutritional products.
She further encouraged NAFDAC, NIPRD, pharmaceutical companies, and NGOs to collaborate on research, funding, and product development to improve hospital and community-based nutritional care.

“We need a national framework that ensures no patient suffers due to a lack of proper nutrition,” the expert stressed.
Conference to Attract Top Medical and Policy Experts
Speaking on the upcoming conference, Dr. Pounds noted that it will bring together leading medical experts, policymakers, and healthcare stakeholders to develop strategies for addressing malnutrition.
Prominent figures expected at the event include Prof. Ali Pate, Coordinating Minister of Health (Special Guest of Honour), Nyesom Wike, Minister of the FCT (Chief Host), Prof. Muhammad Raji Mahmud, Chief Medical Director, National Hospital Abuja (Host), Prof. Audu Bala, President, Nigerian Medical Association (Keynote Speaker), Pharm. Ibrahim Tanko Ayuba, President, Pharmaceutical Society of Nigeria (Guest of Honour), and Prof. Salisu Maiwada Abubaka, President, Nutrition Society of Nigeria (Guest of Honour) admiration.
Pre-Conference Activities
Prof. Raji Mahmud, Chief Medical Director of the National Hospital Abuja, represented by the Chairperson of the Local Organising Committee (LOC), Pharm. Adesola Clara assured that the hospital has the necessary facilities and expertise to host a successful conference. He emphasised that the hospital is fully prepared for the programme.
Also, the WASPEN Central Planning Committee, led by Mrs. Ghinsel Blessing, revealed that pre-conference activities will include a hands-on training workshop on nutritional kits in hospitals, scheduled for June 16, a health walk to raise awareness about hospital malnutrition, expected to be led by First Lady Sen. Oluremi Tinubu.
With malnutrition posing a silent but deadly threat to healthcare outcomes, WASPEN hopes that the Tinubu administration will take decisive action to integrate nutrition-focused interventions into Nigeria’s health policies.
The 2025 WASPEN Clinical Nutrition Conference is expected to be a game-changer in shaping the future of clinical nutrition in Nigeria and West Africa.
Two US biotech companies say the Food and Drug Administration has cleared them to conduct clinical trials of their gene-edited pig kidneys for human transplants.
United Therapeutics along with another company, eGenesis, have been working since 2021 on experiments implanting pig kidneys into humans: initially brain-dead patients and more recently living recipients.
Advocates hope the approach will help address the severe organ shortage. More than 100,000 people in the United States are awaiting transplants, including over 90,000 in need of kidneys.
United Therapeutics’s approval, announced Monday, allows the company to advance its technology toward a licensed product if the trial succeeds.
The study authorization was hailed as a “significant step forward in our relentless mission to expand the availability of transplantable organs,” by Leigh Peterson, the company’s executive vice president.
The trial will initially enroll six patients with the end-stage renal disease before expanding to as many as 50, United Therapeutics said in a statement. The first transplant is expected in mid-2025.
Meanwhile, rival eGenesis said it had received FDA approval in December for a separate three-patient kidney study.
“The study will evaluate patients with kidney failure who are listed for a transplant but who face a low probability of receiving a deceased donor offer within a five-year timeframe,” the company said.
Xenotransplantation — transplanting organs from one species to another — has been a tantalizing yet elusive goal for science.
Early experiments in primates faltered, but advances in gene editing and immune system management have brought the field closer to reality.
Pigs have emerged as ideal donors: they grow quickly, produce large litters, and are already part of the human food supply.
United Therapeutics said trial patients would be monitored for life, assessing survival rates, kidney function, and the risk of zoonotic infections — diseases that jump from animals to humans.
Currently, there is only one living human recipient of a pig organ: Towana Looney, a 53-year-old from Alabama who received a United Therapeutics kidney on November 25, 2024.
She is also the longest-surviving recipient, having lived with a pig kidney for 71 days as of Tuesday. David Bennett of Maryland received a pig heart in 2022 and survived 60 days.
The Swiss government said Thursday it aimed to overhaul its law on medically-assisted reproduction to legalise egg donations and give broader access to sperm donations.
Currently egg donations are not allowed and only married couples can access sperm donations.
The Swiss parliament has long said it wants to change that, and has asked the government with coming up with a proposal to provide broader access.
A government statement said it had “decided to completely revise the law on medically assisted reproduction in order to adapt it to the current context” and had asked the interior ministry to draft a proposed law by the end of next year.
The government said it wants to legalise egg donations in cases where a woman in a couple is infertile, as a parallel to the already legal use of sperm donations in cases of male sterility.
Bern said its priority was “the protection of donors and the welfare of the child”, stressing that “this protection cannot be guaranteed if parents resort to egg donation abroad”.
The government also said it wanted to expand access to both egg and sperm donation to unmarried couples.
After Switzerland legalised same-sex marriage in 2022, married lesbian couples have also had access to sperm donations.
But the government said the current law barring unmarried couples from access to such medically assisted reproduction was “outdated and no longer corresponds to social reality”.
