BACKGROUND: Little is known about whether repeated cycles of hospital accreditation are a robust method to improve quality of care continuously. OBJECTIVE: We aimed to examine the association between compliance with consecutive cycles of accreditation and quality of in-hospital care. METHODS: We conducted a Danish nationwide population-based study including patients aged 18 years treated for acute stroke, chronic obstructive pulmonary disease, diabetes, heart failure or hip fracture at public, non-psychiatric hospitals. From 2012 to 2015, two cycles of national hospital accreditation were completed, resulting in 12 high and 14 low compliant hospitals (Low = partially accredited in both cycles). Our outcome measure was quality of in-hospital care measured by 39 process performance measures (PPMs), reflecting recommendations from the national clinical guidelines by adherence to (i) individual PPMs and (ii) the full bundle of PPMs (all-or-none). We computed adjusted odds ratios (ORs) using logistic regression based on robust standard error estimation for cluster sampling of data at hospital level. RESULTS: In total, 78 387 patient pathways covering 508 816 processes were included, of which 47% had been delivered at high compliant hospitals and 53% at low compliant hospitals, respectively. Compliance with consecutive cycles was not associated with improved quality of in-hospital care (individual: OR = 0.92, 95% confidence interval (CI): 0.77-1.10; All-or-none: OR = 0.87, 95% CI: 0.66-1.15). However, in the second cycle alone, patients treated at partially accredited hospitals had a lower adherence than patients treated at fully accredited hospitals (Individual: OR = 0.84, 95% CI: 0.71-0.99; All-or-none: OR = 0.78, 95% CI: 0.59-1.03). The association was particularly strong among patients treated at partially accredited hospitals required to submit additional documentation. CONCLUSION: Compliance with consecutive cycles of hospital accreditation in Denmark was not associated with improved quality of in-hospital care. However, compliance with the second cycle alone was associated with improved quality of in-hospital care.
