Summary: | Abstract Background The aim of accreditation is to improve quality of care and patient safety. However, studies on the effectiveness of accreditation on clinical outcomes are limited and inconsistent. Comparative studies have contrasted accredited with non-accredited hospitals or hospitals without a benchmark, but assessments of clinical outcomes of patients treated at hospitals undergoing accreditation are sparse. The Faroe Islands hospitals were accredited for the first time in 2017, making them an ideal place to study the impact of accreditation. Objective We aimed to investigate the association between first-time hospital accreditation and length of stay (LOS), acute readmission (AR) and 30-day mortality in the unique situation of the Faroe Islands. Methods We conducted a before and after study based on medical record reviews in relation to first-time accreditation. All three Faroese hospitals were voluntarily accredited using a modified second version of the Danish Healthcare Quality Programme encompassing 76 standards. We included inpatients 18 years or older treated at a Faroese hospital with one of six clinical conditions (stroke/transient ischemic attack (TIA), bleeding gastic ulcer, chronic obstructive pulmonary disease (COPD), childbirth, heart failure and hip fracture) in 2012–2013 designated ‘before accreditation‘or 2017–2018‘ after accreditation’. The main outcome measures were LOS, all-cause AR and all-cause 30-day mortality. We computed adjusted cause-specific hazard rate (HR) ratios using Cox Proportional Hazard regression with before accreditation as reference. The analyses were controlled for age, sex, cohabitant status, in-hospital rehabilitation, type of admission, diagnosis and cluster effect at patient and hospital levels. Results The mean LOS was 13.4 days [95% confidence interval (95% CI): 10.8, 15.9] before accreditation and 7.5 days (95% CI: 6.10, 8.89) after accreditation. LOS of patients hospitalized after accreditation was significantly shorter [overall, adjusted HR = 1.23 (95% CI: ... |
