Abstract

BACKGROUND: General health checks are common elements of health care in some countries. They aim to detect disease and risk factors for disease with the purpose of reducing morbidity and mortality. Most of the commonly used individual screening tests offered in general health checks have been incompletely studied. Also, screening leads to increased use of diagnostic and therapeutic interventions, which can be harmful as well as beneficial. It is therefore important to assess whether general health checks do more good than harm. This is the first update of the review published in 2012.

OBJECTIVES: To quantify the benefits and harms of general health checks.

SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, two other databases and two trials registers on 31 January 2018. Two review authors independently screened titles and abstracts, assessed papers for eligibility and read reference lists. One review author used citation tracking (Web of Knowledge) and asked trial authors about additional studies.

SELECTION CRITERIA: We included randomised trials comparing health checks with no health checks in adults unselected for disease or risk factors. We did not include geriatric trials. We defined health checks as screening for more than one disease or risk factor in more than one organ system.

DATA COLLECTION AND ANALYSIS: Two review authors independently extracted data and assessed the risk of bias in the trials. We contacted trial authors for additional outcomes or trial details when necessary. When possible, we analysed the results with a random-effects model meta-analysis; otherwise, we did a narrative synthesis.

MAIN RESULTS: We included 17 trials, 15 of which reported outcome data (251,891 participants). Risk of bias was generally low for our primary outcomes. Health checks have little or no effect on total mortality (risk ratio (RR) 1.00, 95% confidence interval (CI) 0.97 to 1.03; 11 trials; 233,298 participants and 21,535 deaths; high-certainty evidence, I2 = 0%), or cancer mortality (RR 1.01, 95% CI 0.92 to 1.12; 8 trials; 139,290 participants and 3663 deaths; high-certainty evidence, I2 = 33%), and probably have little or no effect on cardiovascular mortality (RR 1.05, 95% CI 0.94 to 1.16; 9 trials; 170,227 participants and 6237 deaths; moderate-certainty evidence; I2 = 65%). Health checks have little or no effect on fatal and non-fatal ischaemic heart disease (RR 0.98, 95% CI 0.94 to 1.03; 4 trials; 164,881 persons, 10,325 events; high-certainty evidence; I2 = 11%), and probably have little or no effect on fatal and non-fatal stroke (RR 1.05 95% CI 0.95 to 1.17; 3 trials; 107,421 persons, 4543 events; moderate-certainty evidence, I2 = 53%).

AUTHORS' CONCLUSIONS: General health checks are unlikely to be beneficial.


Clinical Comments

Family Medicine (FM)/General Practice (GP)

This area common for general practitioners. If not planned well, it may lead to overuse/abuse of health care facilities.

General Internal Medicine-Primary Care(US)

Health checks do not save lives but they may help build up a relationship with the patient and clinician which may help them later on. I know our current health care system does not really care about that.

General Internal Medicine-Primary Care(US)

I suspect internists who follow this literature closely will not be surprised by these findings. Without a stronger push in the general press, I'm not sure major payors or the government will consider stopping reimbursements for annual check-ups. Although the information challenges a fundamental assumption of American health care, I'm not sure it will change existing clinical practice without a broader educational campaign accompanied by changes in reimbursement for these low-value services.

Public Health

As a clinical pathologist and hospitalist, I would have expected these results. The benefit of this article to me is that it provides updated evidence when I am asked to give an opinion or advice to my colleagues.

Public Health

Interesting review. We need to determine whether interventions for better preventive care have been included and followed. If this is the case and no improvement in health resulted, we need to rethink our education to primary care providers in preventive health.

Public Health

A fairly straightforward meta-analysis of an important question done with the rigour of the Cochrane process with an important conclusion.
