Public health

Heart shaped bowl of pomegranate seeds

 

Public health is all about improving the health of the general population. This can be by preventing disease, prolonging life, and promoting ways to keep healthy. The remit of public health ranges from supporting individuals to dealing with wider issues that impact local communities and whole populations.

Charles-Edward Amory Winslow, an early twentieth century public health expert, called public health both a "science and art". His comment reflects the multidisciplinary nature of the field, which needs a range of specialists ranging from biostatisticians to economists, and from microbiologists to sociologists.

With the advent of the COVID-19 pandemic, Public Health has ever been more important in people’s lives. The launch of the new UK Health Security Agency - UKHSA - in October 2021 is now an integral part of the public health system and plays crucial role in protecting the public, and in planning and responding to health threats in the future.

 

What is public health?

Public health includes all aspects of physical, mental, and social wellbeing and covers a wide range of issues. There are many public health initiatives in the UK and elsewhere in the world. These include encouraging people to breastfeed, have their vaccinations, eat fruit and vegetables, exercise frequently, and wash their hands regularly. 

In many cases, public health is about stopping health problems before they begin. For example, providing free condoms can prevent sexually transmitted diseases, and vaccinations can prevent certain illnesses from spreading. 

Health Education England refer to four main domains of public health:

  • Health protection – helping people to keep safe from risk for example, viruses, environmental or biological threats, food poisoning or radiation
  • Health improvement – improving people’s health by encouraging them to quit smoking or lose weight or by having health and wellbeing initiatives offered and accessible within local communities
  • Healthcare public health – ensuring health services are run efficiently and are accessible to all 
  • Academic Public Health – aims to build the evidence base on which all public health activities is based

You can view an overview of all 4 domains of public health in these short 1 minute videos produced by Health Education England.

What are the benefits of working in public health?

The main benefit is knowing that you’re making a difference to people’s health, whether on an individual level, with a particular group of people, or to a wider population. You will develop knowledge in an area of health and wellbeing and play a key role in preventing ill health and/or promoting ways to stay healthy.

Roles in this area could allow you to gain a range of skills, which will differ depending on the exact role. Skills could range from effective communication and leadership to analytical skills from interpreting data and existing research. The skills for health career framework describe the different levels of skills and knowledge across the public health workforce.

What are the entry requirements for roles in public health?

For some roles such as specialist midwives and nurse roles, you would require additional training in addition to a nursing or midwifery qualifying degree. On the other hand, for a role such as a public health practitioner (which may cover a wide range of job titles from support worker and coordinator roles, through to advanced practitioner positions), there may be differing entry requirements depending on the level of the role.

For more analytical roles, such as statisticians and public health intelligence analysts, a relevant degree is an advantage; analytical courses such as maths, statistics, some social sciences courses, and geography are good examples of these. The NHS Graduate Management Training Scheme has a health informatics strand, which is useful for those wanting to work with data.

If you’re more interested in a role in public health management, you will need to gain experience in management or consider a masters qualification in public health. The NHS Graduate Management Training Scheme has a general management specialty, although this could take you in many different

managerial directions for example, managing primary care or mental health services or managing a service area within an acute NHS hospital or community trust or ambulance service.

The Graduates into Health programme seeks to recruit hard to fill digital, data and technology roles such as information management professionals, cyber and security analysts, software development, IT and project management roles. Since the scheme is very broad, you may be able to focus your training around an aspect of public health.

The Department of Health’s Health Policy Fast Track Scheme is as an opportunity to gain hands on experience of how health policy is developed and delivered by government and gain skills in health care policy and leadership. The scheme also integrates a postgraduate qualification in Health Policy as part of the training.

You may also consider specialty training in public health. Applicants for specialty training in public health come from a wide variety of backgrounds (eg nursing, research, teaching, environmental health, and medicine). Successful completion of training leads to being able to apply for roles as a Public Health Consultant
