[PMID: 39023686 DOI: 10.1007/s13300-024-01606-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2024] [Accepted: 05/31/2024] [Indexed: 07/20/2024] Open
Abstract
Type 2 diabetes (T2D) and lower-extremity peripheral artery disease (PAD) are growing global health problems associated with considerable cardiovascular (CV) and limb-related morbidity and mortality, poor quality of life and high healthcare resource use and costs. Diabetes is a well-known risk factor for PAD, and the occurrence of PAD in people with T2D further increases the risk of long-term complications. As the available evidence is primarily focused on the overall PAD population, we undertook a systematic review to describe the burden of comorbid PAD in people with T2D. The MEDLINE, Embase and Cochrane Library databases were searched for studies including people with T2D and comorbid PAD published from 2012 to November 2021, with no restriction on PAD definition, study design or country. Hand searching of conference proceedings, reference lists of included publications and relevant identified reviews and global burden of disease reports complemented the searches. We identified 86 eligible studies, mostly observational and conducted in Asia and Europe, presenting data on the epidemiology (n = 62) and on the clinical (n = 29), humanistic (n = 12) and economic burden (n = 12) of PAD in people with T2D. The most common definition of PAD relied on ankle-brachial index values ≤ 0.9 (alone or with other parameters). Incidence and prevalence varied substantially across studies; nonetheless, four large multinational randomised controlled trials found that 12.5%-22% of people with T2D had comorbid PAD. The presence of PAD in people with T2D was a major cause of lower-limb and CV complications and of all-cause and CV mortality. Overall, PAD was associated with poor quality of life, and with substantial healthcare resource use and costs. To our knowledge, this systematic review provides the most comprehensive overview of the evidence on the burden of PAD in people with T2D to date. In this population, there is an urgent unmet need for disease-modifying agents to improve outcomes.

Abstract
OBJECTIVES Foot ulceration associated with diabetic foot disease (DFD) and chronic limb-threatening ischaemia (CLTI) presents a complex clinical challenge and failure to heal the wound imposes a significant risk of major limb amputation (MLA). In attempt to accelerate wound healing rates and decrease MLA, tissue engineering research into bio-engineered scaffolds and skin substitutes has become a growing area of interest. Advanced wound therapies such as fetal bovine acellular dermal matrix (FBADM) may have success in the treatment of difficult to heal chronic foot ulcers. The FBADM traps and binds the patients' own epithelial cells to rebuild the dermis layer of the skin. Previous studies have suggested that wounds treated with FBADM had a faster healing rate than wounds managed with conventional dressings. However, these studies excluded foot wounds with chronic exposed bone or tendon, active infection, gangrene, or osteomyelitis and patients with uncontrolled blood glucose levels were excluded. The aim of this study was to assess the efficacy of FBADM for patients admitted to hospital acutely with severe foot ulceration secondary to DFD and CLTI. METHODS Between February 2020 and December 2021, inpatients admitted acutely at a single tertiary centre with a severe non-healing foot ulcer and had a wound suitable for application of a FBADM after primary debridement were included in the study. A severe non-healing foot wound was defined as a Society for Vascular Surgery Wound, Ischaemia, and foot Infection (WIfI) stage of 3 or 4. Participants were prospectively followed up at regular intervals at a multidisciplinary high-risk diabetic foot clinic until June 2022. The primary endpoint was time to wound closure. The secondary endpoints were number of applications of FBADM, readmission rate and amputation-free survival. RESULTS There were 22 patients included in the study with a median age of 71 (50-87) years and 15 were male. Five patients had a WIfI stage of 3 and 17 had a WIfI score of 4. Overall, 14 patients required revascularisation procedures (6 open surgery,8 endovascular intervention). A total of 18 patients achieved complete wound healing with a median time to wound healing of 178 (28-397) days. Two patients underwent a MLA and two patients died prior to complete wound healing. The median length of stay was 16.5 (5-115) days, and 4 patients were readmitted to hospital within 12 months. CONCLUSION FBADM may be a useful adjunct in the acute setting of complex DFD and CLTI ulceration to assist with wound healing. Future comparative prospective studies are required to further validate these preliminary findings.

Avoiding double counting: the effect of bundling hospital events in administrative datasets for the interpretation of rural-urban differences in Aotearoa New Zealand. J Clin Epidemiol 2024; 172:111400. [PMID: 38821135 DOI: 10.1016/j.jclinepi.2024.111400] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2023] [Revised: 05/12/2024] [Accepted: 05/21/2024] [Indexed: 06/02/2024]
Abstract
BACKGROUND AND OBJECTIVES All publicly funded hospital discharges in Aotearoa New Zealand are recorded in the National Minimum Dataset (NMDS). Movement of patients between hospitals (and occasionally within the same hospital) results in separate records (discharge events) within the NMDS and if these consecutive health records are not accounted for hospitalization (encounters) rates might be overestimated. The aim of this study was to determine the impact of four different methods to bundle multiple discharge events in the NMDS into encounters on the relative comparison of rural and urban Ambulatory Sensitive Hospitalization (ASH) rates. METHODS NMDS discharge events with an admission date between July 1, 2015, and December 31, 2019, were bundled into encounters using either using a) no method, b) an "admission flag", c) a "discharge flag", or d) a date-based method. ASH incidence rate ratios (IRRs), the mean total length of stay and the percentage of interhospital transfers were estimated for each bundling method. These outcomes were compared across 4 categories of the Geographic Classification for Health. RESULTS Compared with no bundling, using the date-based method resulted in an 8.3% reduction (150 less hospitalizations per 100,000 person years) in the estimated incidence rate for ASH in the most rural (R2-3) regions. There was no difference in the interpretation of the rural-urban IRR for any bundling methodology. Length of stay was longer for all bundling methods used. For patients that live in the most rural regions, using a date-based method identified up to twice as many interhospital transfers (5.7% vs 12.4%) compared to using admission flags. CONCLUSION Consecutive events within hospital discharge datasets should be bundled into encounters to estimate incidence. This reduces the overestimation of incidence rates and the undercounting of interhospital transfers and total length of stay.

Abstract
OBJECTIVE Preventing untimely death in patients with peripheral artery disease (PAD) requires a detailed understanding of the predominant causes of death (COD). This literature review aims to describe how short- and long-term COD are reported in patients who had surgery for PAD. METHODS A literature review was conducted according to Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines for articles reporting specific causes of mortality in patients who had surgery for all stages of PAD. Articles were included if they reported COD after open surgical or endovascular revascularisation, or major or minor amputation for PAD. Critical appraisals were conducted according to included study types, using the Joanna Briggs Institute tools. RESULTS Cause of death was reported in 21 publications. Twenty were observational and one was a randomised control trial. Study size ranged from 25 to 10,505 patients. Cardiovascular disease was the most prevalent COD in perioperative periods (42.5% from 13 studies). Long-term follow-up ranged from 1 month and 7 years with 15 studies reporting cardiac related mortality as the most frequent cause of death. However, mortality from neoplasia, respiratory disease (including pneumonia and pulmonary emboli), stroke and sepsis were prevalent. Many studies were low-average quality, with few population-based observational studies. CONCLUSION Whilst cardiovascular COD are the most prevalent reasons for mortality in patients with PAD, the proportion of patients dying from neoplasia and respiratory disease is high. Improved reporting standards for COD in studies examining PAD are needed.

Rehabilitation contributes to lower readmission rates for individuals with peripheral arterial disease: A retrospective observational study. Ann Phys Rehabil Med 2023; 66:101768. [PMID: 37883830 DOI: 10.1016/j.rehab.2023.101768] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Revised: 04/23/2023] [Accepted: 04/29/2023] [Indexed: 10/28/2023]
Abstract
BACKGROUND Non-pharmacological interventions, such as rehabilitation, are crucial for the treatment of people with peripheral arterial disease (PAD). Although several studies have shown rehabilitation is effective in improving the functional prognosis of PAD, there is currently insufficient evidence regarding its effect on readmission rates. OBJECTIVES To examine the impact of rehabilitation on readmission rates for people with PAD. METHODS A retrospective analysis of the JMDC hospital database was performed on data from two groups of people aged ≥20 years who were hospitalized between 2014 and 2020 with PAD, as based on a previous diagnosis. Participants were divided according to whether they did, or did not, receive any form of rehabilitation as part of their treatment in hospital. The primary outcome was readmission rates at 30, 60, 90, and 180 days after initial admission. A one-to-one propensity score matching was used to compare readmission rates between rehabilitation and non-rehabilitation groups. RESULTS We included 13,453 people with PAD, of whom 2701 pairs (5402 subjects) were selected after being matched in the rehabilitation and non-rehabilitation groups. The rehabilitation group participants had significantly lower mortality and readmission rates at 30, 60, 90, and 180 days. The odds ratios (95% confidence interval) for both groups were 0.79 (0.69-0.91; 30 days), 0.81 (0.71-0.91; 60 days), 0.78 (0.69-0.88; 90 days), and 0.79 (0.71-0.88; 180 days). CONCLUSIONS This large, nationwide study found that rehabilitation treatment during hospitalization was associated with lower readmission rates and mortality for people following hospitalization with PAD and supports its inclusion as a standard PAD treatment.

Abstract
Background Unplanned readmission to the hospital after discharge is a costly issue for healthcare systems and patients. It is a delicate balance between the resolution of the surgical problem and the length of hospital stay. Most studies have focused on readmissions within 28 or 30 days after discharge, despite data showing that many occur early in this period. This study examined the reasons for unplanned readmission within the first day after discharge. Methods A retrospective cohort analysis of readmissions between 1st May 2016 and 1st May 2021 was undertaken by chart review. Readmissions on the "day of" and the "day after" discharge and their respective index admissions were identified via the hospital's patient administration database, webPAS (DXC Technology, USA). Results There were 126 readmissions (0.5%) across 25,119 admissions. Common reasons for readmission were pain (28%, n=35), readmission for the same diagnosis (21%, n=26), surgical site infection (SSI) (11%, n=14), bleeding (11%, n=14) and ileus (6%, n=7). Analysis of index admissions showed that 18/35 readmissions for pain had inadequate pain management based on pain scores, analgesic use and discharge medications and 7/14 readmissions for SSI did not have appropriate treatment of a recognised SSI or did not have antibiotic prophylaxis guidelines adhered to. Fourteen of 26 readmissions for the same diagnosis received just continuation of treatment initiated at index admission. Conclusion Pain is the most common reason for readmission within the first day after discharge in surgical patients. Better pain management, following antibiotic prophylaxis guidelines, and involving patients in discharge planning could prevent many readmissions.

Abstract
The epidemiology of severe PAD, as characterized by short-distance intermittent claudication (IC) and chronic limb-threatening ischemia (CLTI), remains undefined in New Zealand (NZ). This was a retrospective observational cohort study of the Midland region in NZ, including all lower limb PAD-related surgical and percutaneous interventions between the 1st of January 2010 and the 31st of December 2021. Overall, 2541 patients were included. The mean annual incidence of short-distance IC was 15.8 per 100,000, and of CLTI was 36.2 per 100,000 population. The annual incidence of both conditions was greater in men. Women presented 3 years older with PAD (p < 0.001). Patients with short-distance IC had lower ipsilateral major limb amputation at 30 days compared to CLTI (IC 2, 0.3% vs. CLTI 298, 16.7%, p < 0.001). The 30-day mortality was greater in elderly patients (<65 years 2.7% vs. ≥65 years 4.4%, p = 0.049), but did not differ depending on sex (females 36, 3.7% vs. males 64, 4.1%, p = 0.787). Elderly age was associated with a worse survival for both short-distance IC and CLTI. There was a worse survival for females with CLTI. In conclusion, PAD imposes a significant burden in NZ, and further research is required in order to reduce this disparity.
