OBJECTIVE -There is a lack of continuous longitudinal population-based data on lower extremity amputation (LEA) in the U.K. We present here accurate data on trends in diabetesrelated (DR) LEAs and non-DRLEAs in the South Tees area over a continuous 5-year period.RESEARCH DESIGN AND METHODS -All cases of LEA from 1 July 1995 to 30 June 2000 within the area were identified. Estimated ascertainment using capture-recapture analysis approached 100% for LEAs in the area. Data were collected longitudinally using the standard method of the Global Lower Extremity Amputation Study protocol.RESULTS -Over 5 years there were 454 LEAs (66.3% men) in the South Tees area, of which 223 were diabetes related (49.1%). Among individuals with diabetes, LEA rates went from 564.3 in the first year to 176.0 of 100,000 persons with diabetes in the fifth year. Over the same period, non-DRLEAs increased from 12.3 to 22.8 of 100,000 persons without diabetes. The relative risk of a person with diabetes undergoing an LEA went from being 46 times that of a person without diabetes to 7.7 at the end of the 5 years. The biggest improvement in LEA incidence was seen in the reduction of repeat major DRLEAs.CONCLUSIONS -Our data show that in the South Tees area at a time when major non-DRLEA rates increased, major DRLEA rates have fallen. These diverging trends mark a significant improvement in care for patients with diabetic foot disease as a result of better organized diabetes care.

AimsTo describe trends in the incidence of non-traumatic amputations among people with and without diabetes and estimate the relative risk of an individual with diabetes undergoing a lower extremity amputation compared to an individual without diabetes in the Republic of Ireland.MethodsAll adults who underwent a nontraumatic amputation during 2005 to 2009 were identified using HIPE (Hospital In-patient Enquiry) data. Participants were classified as having diabetes or not having diabetes. Incidence rates were calculated using the number of discharges for diabetes and non-diabetes related lower extremity amputations as the numerator and estimates of the resident population with and without diabetes as the denominator. Age-adjusted incidence rates were used for trend analysis.ResultsTotal diabetes-related amputation rates increased non-significantly during the study period; 144.2 in 2005 to 175.7 in 2009 per 100,000 people with diabetes (p = 0.11). Total non-diabetes related amputation rates dropped non-significantly from 12.0 in 2005 to 9.2 in 2009 per 100,000 people without diabetes (p = 0.16). An individual with diabetes was 22.3 (95% CI 19.1–26.1) times more likely to undergo a nontraumatic amputation than an individual without diabetes in 2005 and this did not change significantly by 2009.DiscussionThis study provides the first national estimate of lower extremity amputation rates in the Republic of Ireland. Diabetes-related amputation rates have remained steady despite an increase in people with diabetes. These estimates provide a base-line and will allow follow-up over time.

BackgroundAccurate estimates of the burden of diabetes are essential for future planning and evaluation of services. In Ireland, there is no diabetes register and prevalence estimates vary. The aim of this review was to systematically identify and review studies reporting the prevalence of diabetes and complications among adults in Ireland between 1998 and 2015 and to examine trends in prevalence over time.MethodsA systematic literature search was carried out using PubMed and Embase. Diabetes prevalence estimates were pooled by random-effects meta-analysis. Poisson regression was carried out using data from four nationally representative studies to calculate prevalence rates of doctor diagnosed diabetes between 1998 and 2015 and was also used to assess whether the rate of doctor diagnosed diabetes changed over time.ResultsFifteen studies (eight diabetes prevalence and seven complication prevalence) were eligible for inclusion. In adults aged 18 years and over, the national prevalence of doctor diagnosed diabetes significantly increased from 2.2 % in 1998 to 5.2 % in 2015 (p trend ≤ 0.001). The prevalence of diabetes complications ranged widely depending on study population and methodology used (6.5–25.2 % retinopathy; 3.2–32.0 % neuropathy; 2.5-5.2 % nephropathy).ConclusionsBetween 1998 and 2015, there was a significant increase in the prevalence of doctor diagnosed diabetes among adults in Ireland. Trends in microvascular and macrovascular complications prevalence could not be examined due to heterogeneity between studies and the limited availability of data. Reliable baseline data are needed to monitor improvements in care over time at a national level. A comprehensive national diabetes register is urgently needed in Ireland.Electronic supplementary materialThe online version of this article (doi:10.1186/s12889-016-2818-2) contains supplementary material, which is available to authorized users.

In the absence of a national diabetes register, these findings provide a robust estimate of the national prevalence of diagnosed Type 2 diabetes and level of complications among adults aged 50 years and over in Ireland.

This is the first prevalence estimate of DCN in Ireland. These data suggest diagnosis of DCN is missed in the acute phase. There exists a significant risk of diabetic foot ulceration and amputation with DCN.
