Compliance with accreditation and recommended hospital care-a Danish nationwide population-based study.

OBJECTIVE

To examine the association between compliance with accreditation and recommended hospital care.

DESIGN

A Danish nationwide population-based follow-up study based on data from six national, clinical quality registries between November 2009 and December 2012.

SETTING

Public, non-psychiatric Danish hospitals.

PARTICIPANTS

Patients with acute stroke, chronic obstructive pulmonary disease, diabetes, heart failure, hip fracture and bleeding/perforated ulcers.

INTERVENTIONS

All hospitals were accredited by the first version of The Danish Healthcare Quality Programme. Compliance with accreditation was defined by level of accreditation awarded the hospital after an announced onsite survey; hence, hospitals were either fully (n = 11) or partially accredited (n = 20).

MAIN OUTCOME MEASURES

Recommended hospital care included 48 process performance measures reflecting recommendations from clinical guidelines. We assessed recommended hospital care as fulfilment of the measures individually and as an all-or-none composite score.

RESULTS

In total 449 248 processes of care were included corresponding to 68 780 patient pathways. Patients at fully accredited hospitals had a significantly higher probability of receiving care according to clinical guideline recommendations than patients at partially accredited hospitals across conditions (individual measure: adjusted odds ratio (OR) = 1.20, 95% CI: 1.01-1.43, all-or-none: adjusted OR = 1.27, 95% CI: 1.02-1.58). For five of the six included conditions there were an association; the pattern appeared particular strong among patients with acute stroke and hip fracture (all-or-none; acute stroke: adjusted OR = 1.39, 95% CI: 1.05-1.83, hip fracture: adjusted OR = 1.57, 95% CI: 1.00-2.49).

CONCLUSION

High compliance with accreditation standards was associated with a higher level of evidence-based hospital care in Danish hospitals.
