What You'll Learn
Patient care
The primary function of a hospital is to provide patient care, including diagnosis, treatment, and disease prevention. Hospitals offer both curative and preventive services to treat and prevent a range of medical conditions.
Inpatient and Outpatient Services
Hospitals provide inpatient services for patients who require overnight stays, as well as outpatient services for consultations, minor procedures, and follow-up care. Inpatient services cater to those who need more intensive treatment, monitoring, or surgery, while outpatients can return home after their appointment or procedure.
Emergency Department
A critical aspect of patient care is the hospital's emergency department, which handles accidents and medical emergencies. This department is equipped to deal with unexpected illnesses, injuries, and crises, providing immediate care to stabilize patients and address life-threatening conditions.
Nursing Services
Nursing services are a cornerstone of patient care in hospitals. Registered nurses and their teams provide continuous care, including administering medications, monitoring vital signs, assisting with activities of daily living, and offering emotional support to patients and their families.
Paramedical Departments
Paramedical departments play a crucial role in supporting patient care. These include:
- Radiology: This department provides radiological examinations and treatments while adhering to safety protocols to protect against radiological exposure.
- Dietary: The dietary department ensures patients' nutritional needs are met, with special diets prescribed by a dietician based on individual medical conditions.
- Pharmacy: Responsible for securely storing and dispensing medications and intravenous (IV) fluids, the pharmacy plays a vital role in patient care by supplying the necessary medications as prescribed by doctors.
Specialist Services
Hospitals often have departments catering to specific medical disciplines, such as obstetrics and gynecology, cardiology, oncology, ophthalmology, and psychiatry. These departments provide specialized patient care, treatments, and surgeries, ensuring that patients receive focused attention for their specific health needs.
In summary, the patient care function of hospitals encompasses a wide range of services, from emergency care to long-term treatment and support. Hospitals aim to provide holistic care by addressing the physical, nutritional, and medicinal needs of patients through the dedicated work of specialized staff and the utilization of advanced equipment.

Diagnosis and treatment
The paramedic departments include laboratories, radiology, dietary, and pharmacy. Radiology provides radiological examinations and treatment, and must have safety precautions to prevent radiological exposure to patients and staff. The dietary department meets the dietary requirements of patients, with special diets served according to patient conditions. The pharmacy department stores and dispenses medicines and IV fluids.
The emergency department treats accidents and medical emergencies. Hospitals provide diagnostic and therapeutic patient services for medical conditions and have organised physician and nursing staff. The World Health Organisation (WHO) considers an establishment to be a hospital if it is permanently staffed by at least one physician, can offer inpatient accommodation, and can provide active medical and nursing care.
Hospitals may provide rehabilitative services to athletes, including first aid, nutrition, and exercise prescription. They may also provide home and community nursing services, such as 'antibiotics at home' and specialist community nurse practitioners. These nurses can prescribe medication and work with GPs to help patients, keeping them informed of any changes to medication.

Inpatient and outpatient services
Hospitals are licensed institutions that primarily function to provide diagnostic and therapeutic patient services for various medical conditions. They are equipped with organised physician and nursing staff to provide continuous care and treatment to patients. Inpatient and outpatient services are two distinct categories of care provided by hospitals, differing primarily in the duration of hospital stay.
Inpatient care involves patients being admitted and staying in a hospital or specialised inpatient facility for at least one night. This type of care is typically required for severe ailments, treatments, surgeries, or trauma that necessitate constant monitoring, repeated or continuous treatment, and recovery time. Inpatient care is often associated with more serious medical conditions and can be planned, such as for knee replacement surgery or childbirth, or unplanned, like in the case of a traumatic injury. It provides patients with access to a comprehensive range of services and professionals within a single facility, such as nurses, doctors, and other healthcare specialists.
On the other hand, outpatient care does not require an overnight stay in a hospital. It encompasses a wide range of services that can be provided in a hospital, walk-in clinic, outpatient surgery centre, or a doctor's office. Outpatient services include diagnostic tests, treatments, consultations, exams, and some emergency care procedures. Examples of outpatient care include annual check-ups, blood tests, routine mammograms, colonoscopies, and certain same-day surgeries. Outpatient care is typically utilised for less critical or routine medical situations that do not necessitate an extended hospital stay.
The distinction between inpatient and outpatient care is essential for patients to understand, as it provides them with more control over their healthcare choices and allows them to anticipate costs and compare health plans accordingly. While inpatient care tends to be more expensive due to the overnight stay and extensive use of resources, outpatient care can often be covered by health plans as part of preventive care, giving patients financial relief.
It is worth noting that the type of care provided, whether inpatient or outpatient, largely depends on the patient's condition and the severity of their medical issue. In some cases, patients may have a choice between inpatient and outpatient care, while in other cases, the nature of the situation dictates the type of care. Additionally, certain specialties, such as mental health care, offer both inpatient and outpatient services, allowing patients to choose the level of support and therapy time that aligns with their needs.

Medical education and training
Hospitals are healthcare institutions that provide treatment to patients using specialised staff and equipment. They are designed to care for the sick, injured, and well, offering complete healthcare services that are both curative and preventive.
The medical education and training offered by hospitals can vary depending on the specific programmes and resources available. However, hospitals generally provide a combination of theoretical instruction and practical, hands-on training. This includes clinical rotations, where trainees work directly with patients under the supervision of experienced medical professionals.
During their training, medical professionals learn about various medical disciplines, such as general medicine, specialised medicine, general surgery, specialised surgery, obstetrics, orthopaedics, cardiology, and psychiatry. They develop skills in diagnosis, treatment, patient care, and medical research. Hospitals also provide opportunities for continuous professional development, allowing medical professionals to update their knowledge and skills throughout their careers.
In addition to training healthcare workers, hospitals may also offer educational programmes for patients and their families. These programmes can include health education, teaching patients about their specific medical conditions, providing instructions for taking medication, and offering guidance on lifestyle changes to improve health and prevent disease.
By investing in medical education and training, hospitals contribute to the development of a skilled healthcare workforce and empower patients to take an active role in their health, ultimately improving the overall quality of healthcare in the community.

Preventative healthcare
Hospitals are licensed institutions with at least six beds, providing diagnostic and therapeutic patient care for various medical conditions. They are staffed by physicians and nurses and offer inpatient accommodation. While hospitals primarily treat patients with existing conditions, preventative healthcare is also a key function.
For example, in the case of diabetes, effective interventions have included multidisciplinary teams, telephone-based follow-up, and self-management training, leading to reduced hospital admissions and healthcare costs. Similarly, for heart failure, collaborative care approaches have shown positive outcomes in improving depressive symptoms. These interventions not only improve patient health but also reduce the economic burden on the healthcare system by lowering hospital admissions and treatment costs.
Despite the proven benefits of preventative healthcare, its utilisation is often low. This is not due to a lack of awareness but rather an implementation gap, as financial incentives are typically aligned with treating diseases rather than preventing them. Payers and healthcare providers can address this gap by adopting value-based payment models that incentivise the utilisation of preventive services, thereby improving patient outcomes and reducing the overall cost burden on the healthcare system.
