Osteoarthritis and risk of hospitalization for ambulatory care sensitive conditions: A general population-based cohort study [link]Paper  doi  abstract   bibtex   
To determine the association between osteoarthritis (OA) and risk of hospitalization for ambulatory care sensitive conditions (HACSCs).We included all individuals aged 40–85 years who resided in Skåne, Sweden on 31st December 2005 with at least one healthcare consultation during 1998–2005 (n = 515 256). We identified those with a main diagnosis of OA between January 1, 1998 and December 31, 2016. People were followed from January 1st 2006 until an HACSC, death, relocation outside Skåne, or December 31st 2016 (whichever occurred first). OA status was treated as a time-varying covariate (those diagnosed before January 1, 2006 considered as exposed for whole study period). We assessed relative (hazard ratios (HRs) using Cox proportional hazard model) and absolute (hazard difference using additive hazard model) effects of OA on HACSCs adjusted for potential confounders.Crude incidence rates of HACSCs were 239 (95% CI 235, 242) and 151 (150, 152) per 10 000 person-years among OA and non-OA persons, respectively. The OA persons had an increased risk of HACSCs (HR [95% CI] 1.11 [1.09, 1.13]) and its subcategories of medical conditions except chronic obstructive pulmonary disease (HR [95% CI] 0.86 [0.81, 0.90]). There were 20 (95% CI 16, 24) more HACSCs per 10 000 person-years in OA compared with non-OA persons. While HRs for knee and hip OA were generally comparable, only knee OA was associated with increased risk of hospitalization for diabetes.OA is associated with an increased risk of HACSCs, highlighting the urgent need to improve outpatient care for OA patients.
