The think tank has been investigating how PROMs (patient-reported outcome measures) can be used to influence decision making in the NHS.
The resulting report Getting the Most Out of PROMs suggests a points system could be used to prioritise patients for treatment and reduce variation in GP referring.
PROMs are an assessment of a person's health and quality of life, completed by the patient often following treatment but sometimes ahead of it.
The tools are currently used to assess the outcomes of hospital operations but are being developed for use in patients with anxiety and depression.
The King's Fund report cites examples from the New Zealand and Canadian health systems, where patients complete a PROM-type questionnaire before treatment to assess how their condition affects their quality of life.
Patients receive a ‘score' in points, based on their needs and the likelihood treatment will improve their quality of life.
‘Those who do not have enough points to merit surgery are not offered surgery,' the report says. ‘This is, in effect, an explicit form of "rationing".'
The reports' authors assess whether PROMs data can ‘guide referral practices, to ensure that the people who receive healthcare are those that will benefit from it the most'.
Dr Ray Naden and Alison Barber, from New Zealand's ministry of health, write that ‘the use of points systems marks a departure from a reliance on paternalistic, potentially idiosyncratic, decisions by individual clinicians'.
The Conservatives last year pledged to link GP funding to the local population's health and to base QOF payments on PROMs and outcomes.
