Therapeutic inertia in the management of type 2 diabetes mellitus is common, with causes at the patient, health-care professional and health-care system levels. The majority of recent strategies to address therapeutic inertia usually consisted of multiple interventions, but rarely targeted more than 1 level. Most strategies used educational interventions among patients or health-care professionals, but gaps were found in addressing determinants of behaviour change.
ObjectiveTo describe the direct and indirect cost estimates of dry eye disease (DED), stratified by disease severity, and the impact of DED on quality of life (QoL) in Canadian patients.Methods and analysisA prospective, multicentre, observational, cross-sectional study was conducted at six sites across Canada. Eligible patients completed a 20 min survey on demography, general health, disease severity, QoL and direct (resource utilisation and out-of-pocket expenses for the past 3–24 months) and indirect costs (absenteeism and presenteeism based on Work Productivity and Activity Impairment questionnaire responses). Subgroup analyses were performed according to DED severity and presence of Sjögren’s syndrome.ResultsResponses from 146 of 151 participants were included in the analysis. DED was rated as moderate or severe by 19.2% and 69.2% of patients, respectively. Total mean annual costs of DED were $C24 331 (Canadian dollars) per patient and increased with patient-reported disease severity. Mean (standard deviation [SD]) indirect costs for mild, moderate and severe disease were $C5961 ($C6275), $C16 525 ($C11 607), and $C25 485 ($C22,879), respectively. Mean (SD) direct costs were $C958 ($C1216), $C1303 ($C1574) and $C2766 ($C7161), respectively. QoL scores were lowest in patients with Sjögren’s syndrome (8.2% of cohort) and those with severe DED.ConclusionThis study provides important insights into the negative impact of DED in a Canadian setting. Severe DED was associated with higher direct and indirect costs and lower QoL compared with those with mild or moderate disease. Increased costs and poorer QoL were also evident for patients with DED plus Sjögren’s syndrome versus DED alone.
Aim
To better understand the healthcare burden of people with type 2 diabetes (T2D) and estimated glomerular filtration rate (eGFR) < 90 mL/min/1.73 m2 in Ontario, Canada.
Materials and Methods
We used administrative data to evaluate the prevalence of T2D, eGFR < 90 mL/min/1.73 m2 and adverse cardiovascular co‐morbidities in individuals aged ≥ 30 years living in Ontario, Canada. We also examined incremental healthcare costs and healthcare resource utilization (HCRU) for these patients with specific incident cardiovascular and renal outcomes, in comparison with controls without these outcomes.
Results
While the prevalence of T2D in the general population aged ≥ 30 years in Ontario increased by 1.8% over a 5‐year period (2011‐2012 to 2015‐2016), the prevalence of eGFR < 90 mL/min/1.73 m2 among people with T2D increased by 35%. In comparison with corresponding controls without these outcomes, the per patient average total costs (Canadian dollars) over a 2‐year analysis period were higher for patients with cardiovascular disease/chronic kidney disease related death ($69 827; n = 32 407), doubling of serum creatinine ($52 260; n = 22 825), those who started dialysis ($150 627; n = 3499) or received a kidney transplant ($50 664; n = 651). Similarly, HCRU was significantly greater for patients with these incident outcomes.
Conclusions
This real‐world retrospective study highlights an increasing prevalence of T2D, eGFR < 90 mL/min/1.73 m2, and the substantially higher healthcare costs and HCRU when these patients have adverse cardiovascular and renal outcomes. The existence of such a large economic burden underpins the importance of preventing these diabetes‐related complications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
