IntroductionType 2 diabetes (T2D) is a common condition that, if left untreated or poorly managed, can lead to adverse microvascular and macrovascular complications. We estimated the prevalence and incidence of microvascular and macrovascular complications among patients newly diagnosed with T2D within a US integrated healthcare system.Research design and methodsWe conducted a retrospective cohort study among patients newly diagnosed with T2D between 2003 and 2014. We evaluated 13 complications, including chronic kidney disease (CKD), cardiovascular disease (CVD), and all-cause mortality through 2018. Multivariable Cox proportional hazards models were used to study factors associated with complications.ResultsWe identified 135 199 patients with incident T2D. The mean age was 58 years, and 48% were women. The prevalence of CKD was the highest of the complications at the time of T2D diagnosis (prevalence=12.3%, 95% CI 12.2% to 12.5%), while the prevalence of CVD was among the lowest at 3.3% (95% CI 3.2% to 3.3%). The median time to incidence of a T2D complication ranged from 3.0 to 5.2 years. High incidence rates (95% CI) of T2D complications included peripheral neuropathy (26.9, 95% CI 26.5 to 27.3 per 1000 person-years (PY)), CKD (21.2, 95% CI 20.9 to 21.6 per 1000 PY), and CVD (11.9, 95% CI 11.7 to 12.2 per 1000 PY). The trend of 5-year incidence rates of T2D complications by diagnosis year decreased over time (p value<0.001). Older age, non-Hispanic white race/ethnicity, sex, higher A1C, smoking, and hypertension were associated with increased CKD and CVD incidence.ConclusionThough incidence rates of T2D complications were lower in more recent years (2010–2014), a significant proportion of patients had complications at T2D diagnosis. Earlier preventive therapies as well as managing modifiable factors may help delay the development and progression of T2D complications.

Patients with type 2 diabetes mellitus (T2D) are at risk of various comorbidities. We investigated the timing of incident T2D complications over the course of 15 years and clinical characteristics associated with those complications in a large U.S. integrated healthcare system. We identified incident T2D between 2003-2014 with a validated algorithm using electronic health records. T2D complications included micro- and macro-vascular diseases, depression, and all-cause mortality. We calculated incidence rates per 1000 person-years and median time to developing each complication through 2018. Multivariable Poisson regression models were used to investigate factors associated with early T2D complications defined as shorter than the median time to incidence. We identified 135,199 patients with newly diagnosed T2D and followed them for a median six years [mean age 58 years, 48% female, 36% White, 35% Hispanic, 12% Black, 13% Asian]. Median times to incidence of depression, peripheral vascular disease, stable angina, and chronic kidney disease (CKD) were shorter than median times to incidence of lower extremity amputation, stroke, and heart failure (Table). Having hypertension and lower eGFR were associated with shorter time to CKD whereas male was associated with shorter time to composite cardiovascular events. Older age and a higher comorbidity score were associated with shorter time to both. Disclosure J. An: Research Support; Self; Merck & Co., Inc., Novartis AG. G.A.

Transgender and gender diverse individuals face health disparities such as higher HIV prevalence, but limited studies have found low PrEP uptake among these populations. To understand both patient and provider perspectives regarding PrEP care for transgender and gender diverse individuals, we conducted a mixed-methods study at Kaiser Permanente Southern California from September 2020 to October 2021. Transgender and gender diverse adults (N = 396) participated in a web-based survey, and qualitative interviews were subsequently conducted with a subset of survey respondents (N = 32) and healthcare providers (N = 8). Among survey respondents, > 75% were familiar with PrEP, and > 40% reported at least one HIV risk factor, but < 5% had taken PrEP. Interview themes included increasing providers’ inclusivity in primary care for transgender and gender diverse patients, and reducing logistical barriers and costs associated with PrEP-related visits. To improve PrEP uptake among transgender and gender diverse individuals, barriers across patient, provider, and health system levels must be addressed.
