Simple prognostic tool for GPs could more accurately predict disease outcomes in musculoskeletal conditions

June 12, 2013

GPs could more accurately predict the likely progression of disease in patients with musculoskeletal conditions by asking them a simple set of generic questions during their very first consultation, new research funded by Arthritis Research UK has shown.

Asking patients about how long their pain lasts; whether it affects their daily activities; and if more than one joint is affected, was found to be more effective in predicting disease outcome than a GP relying on their prognostic alone, according to lead author Professor Christian Mallen from the Arthritis Research UK Primary Care Centre at Keele University in the UK.

Although some GPs would ask these questions without such a prompt, the aim is to encourage GPs to take a more of a systematic and structured approach to ensure that key prognostic information is gathered.

The improvement in prognostic accuracy was attributable to correcting the GPs' tendency to have an over-optimistic expectation of the outcome of disease.

A total of 194 of 403 participants were classified as having an unfavourable outcome at six months. Adding three simple questions (duration of their present episode of pain; whether pain interfered with their daily activities; and whether the pain was in one of more ) into their initial consultation improved the ability of GPs to predict the outcome of their condition in 69% of cases. When GPs relied on their own prognostic judgement it was only 62%.

The research is published in the online Journal of the American Medical Association (JAMA).

The primary care centre is spearheading research to increasingly 'stratify' patients according to their need so that higher risk patents who are likely to do badly and have a poor long-term prognosis can be offered care specifically tailored to their needs.

Professor Mallen carried out a prospective observational of patients aged 50 or over presenting with non- in one of five participating .

Professor Mallen commented:" Estimating the likely future course of musculoskeletal conditions is an important consideration on primary care consultation for both patients and health professionals, as it enables them to plan and manage the condition.

An accompanying commentary in JAMA said: "In order to tailor care by impact and prognostic risk, we need brief assessment tools which are suitable for routine use in clinics. Simple generic questions could make routine prognostic evaluation of diverse patients with musculoskeletal pain more practical and efficient."
