A locum is a person who temporarily fulfills the duties of another. For example, a locum tenens physician is a physician who works in the place of the regular physician when that physician is absent, or when a hospital/practice is short-staffed. These professionals are still governed by their respective regulatory bodies, despite the transient or freelance nature of their positions.

The word locum is short for the Latin phrase locum tenens, which means "place holder", akin to the French lieutenant. The abbreviated form "locum" is common in Australia, Canada, Ireland, Malaysia, Singapore, New Zealand, South Africa and the United Kingdom; unlike in Latin its plural is locums. In the United States, the full length "locum tenens" (plural: locum tenentes) is preferred, though for some particular roles, alternative expressions (e.g., "substitute teacher") may be more commonly used.

In healthcare

In the UK, the NHS on average has 3,500 locum doctors working in hospitals on any given day,[1] with another 17,000 locum general practitioners.[2] Many of these locum hospital doctors are supplied by private agencies through a national framework agreement that the NHS holds with 51 private agencies. NHS figures show that approximately 80% of hospital locum positions are filled by agencies on this framework. The remaining 20% are filled by agencies working outside this agreement. Locum agencies are common reference points for doctors wishing to work in this market. According to a report published by Royal College of Surgeons, the NHS spent approximately £467 million on locum doctors through agencies in the year 2009/2010.

On the other hand, GP locums (freelance general practitioners) mostly work independently (c. 75%) from locum agencies either as self-employed or via freelance GP chambers based on the NASGP's Sessional GP Support Team (SGPST) model. Some GPs in the UK have been employed by the Primary Care Trusts (PCTs) to provide locum cover. However, PCTs were abolished in 2013 and replaced by the CCGs (Clinical Commissioning Groups).[3] CCGs are now starting to employ salaried GPs with locum roles. Locum GPs are expected to be flexible, adaptable, resourceful, professional, quick to establish relationships, familiar with different IT systems, and able to independently manage risks.

Advantages and disadvantages

Locums provide a ready means for organizations to fill positions that are either only temporarily empty (during sickness, leave or for other reasons) or for which no long-term funding is available. Locumming also allows a professional to try (and get experienced in) a wide range of work environments or specialisation fields which a permanent employee may not encounter.[4][5]

Some locum recruitment agencies do now offer pre-employment training (PET) to Foreign Medical Graduates before the start of their first professional experience in the UK Primary Care System.[6]

However, the locum situation also has a number of disadvantages – the transient nature means extra stress and work for the locums whenever they have to fit into a new position,[5] and for the hiring organisation, this generally means that the required flexibility (and often, the lack of a guaranteed income) has to be rewarded with high salaries.[4] These may in the long term create higher costs for the hiring organisation than adding more full-time positions (especially in highly skilled, accredited professions, and unlike the situation in some professions where cheap temporary labour or significant use of interns actually undercuts wages and reduces total staff costs).

Also, and especially true in professions where knowing all procedures and past case histories is important (such as for doctors working on patients, who may dislike not being treated by their own doctor, or by constantly shifting doctors),[4] locums may provide lesser-quality work (or be seen as posing such a risk, fairly or not).[4] Further, locums often experience resentment from permanent staff, for example because they are paid more, or because they are considered to shoulder less responsibility.[4]
