At some point or other, you may have heard health professionals talk about primary, secondary or tertiary health care. These terms, which are used throughout the world, refer to levels of care, for cases ranging from mild to serious.

Primary Care

The primary care level is the “gatekeeper”, the first point of medical consultation. As a patient you are usually seen by a primary care physician, also called a general practitioner or family physician. Primary care is provided at a doctor’s office, health center or Urgent Care center. The Emergency Room is also often a source of primary care for the un- or under-insured.

According to the New England Healthcare Institute, demand for primary care continues to grow as patients become older and sicker. At the same time, there’s an increasing shortage of general practitioners. To meet the demand, physicians are starting to utilize nurse practitioners and physician assistants.

Secondary Care

Medical specialists and other health professionals, who typically don’t have initial contact with patients, provide secondary care. For example, a primary care physician might refer a patient to a cardiologist, rheumatologist, or a urologist or other specialty physician. Some secondary care physicians do not require a patient to have a referral from a primary care practitioner.

Another category of secondary care is hospital care, or acute care. The term covers care as an admitted patient in a hospital, a visit to a hospital ER, attendance in childbirth, medical imaging (radiology) services and care within an intensive care unit.

Physical therapists, respiratory therapists, speech therapists, occupational therapists and other allied health professionals often work in secondary care.

Tertiary Care

Patients being treated requiring a higher level of care in a hospital may be considered to be in tertiary care. Physicians and equipment at this level are highly specialized. Tertiary care services include such areas as cardiac surgery, cancer treatment and management, burn treatment, plastic surgery, neurosurgery and other complicated treatments or procedures.

A fourth level of care, quaternary care, is a more complex level of tertiary care. Uncommon, highly specialized and experimental treatments and procedures are considered to be at the quaternary care level.

List of Services Offered by Hospitals

Hospital Services may be defined as facilities and utilities offered by hospitals in the form of medical and surgical assistance, laboratory and pharmaceutical provisions, staff and specialists, advanced equipment etc.

In short, hospital services include anything and everything that hospitals offer to their recipients. Most of these depend on the hospital’s motto, customer requirements and expectations.

Depending on the type of hospitals, the services they offer vary. However, every hospital needs to provide some core and mandatory services.

Listed below are some common and most required hospital services offered by every healthcare institute.

Ward Facilities:

 One of the distinguishing factors that marks hospitals unique, with respect to other health facilities; such as, clinics and care centers is that they provide both inpatient and outpatient care provisions.

Every hospital needs to have ward allotment for patients suffering from severe illness and injuries. This enables care givers to monitor health conditions continuously and thereby, accurate treatment procedures can be opted for.

In India, hospitals provide different types of wards for patients. Some of these are; general wards, private wards, semi private wards etc. Depending on choice and costs, patients can opt for any type of ward. Modern hospitals are sufficiently equipped to provide huge comfort to patients and are no less, or sometimes better than homes.


Nurses employed by hospitals function as connecting bridges between doctors and the patients they treat. Nurses look after the overall well being of patients. They ensure that all health related instructions given by doctors are implemented and followed by patients.

Nurses are employed in different departments within hospitals. Specialized hospitals hire trained nurses who are technically sound to perform advanced tasks relevant to diagnosis, treatment and care of sick ones.

Every hospital therefore has a separate nursing department which forms a core segment of hospitalization.

 Out patient Department( OPD): 

Every hospital needs to have an OPD (Outpatient Department) as one of the core services rendered. A set of skilled doctors along with technicians must be available, who can assist patients in preliminary diagnosis and related treatments.

Doctors prescribe medicines or diagnostic tests to evaluate a patient’s health condition. They are also required to be available for follow up visits to monitor conditions and treatment procedures. Depending on the response, patients are either asked for admission or specialized services such as surgeries.

Intensive Care Unit(ICU):

 Almost every hospital in India provides ICU facilities for patients suffering from adverse health conditions. ICUs need to be equipped with modern technical apparatus and skilled professionals who can render best services. Depending on the type of hospital and services they focus on, there can be different types of ICUs. Some of them are, Neuro ICU, Coronary Care Unit, Neonatal ICU, Psychiatric ICU etc.

Pharmacy and Diagnosis:

 Most hospitals in India do maintain a pharmacy and diagnostic department of their own. This is a very important segment as easy and quick availability of medicines and other equipment required for treatment procedure is vital to render best healing services.

 However, many times, hospitals do not guarantee the availability of all medicines that are being prescribed and therefore independent pharmacies are equally important. Further, 9 out of 10 hospitals maintain a separate laboratory and diagnostic section where related tests can be carried out. Again, similar to pharmacies, these diagnostic departments do not offer a wide variety of tests and analysis for patients.

These were the five most common services related to hospitalization. The more advanced a hospital is in rendering services, the more popular and desirable it becomes. Indian hospitals are aiming at becoming more advanced in providing best and upgraded amenities to patients that can ultimately enhance their treatment procedures. Thus, with upgraded hospital features, the health care system in India will be at the top of providing best medical solutions to the entire population.
