Factors associated with cellulitis in lymphoedema of the arm - an international cross-sectional study (LIMPRINT).

BACKGROUND: Lymphoedema is a globally neglected health care problem and a common complication following breast cancer treatment. Lymphoedema is a well-known predisposing factor for cellulitis, but few have investigated the risk factors for cellulitis in this patient cohort on an international level. The aim of this study was to identify the frequency of cellulitis in patients with lymphoedema of the arm, including potential risk factors for cellulitis. METHODS: An international, multi-centre, cross-sectional study including patients with clinically assessed arm lymphoedema. The primary outcome was the incidence of cellulitis located to the arm with lymphoedema within the last 12 months, and its potential associated risk factors. The secondary outcome was life-time prevalence of cellulitis. Adults with clinically-assessed arm lymphoedema/chronic oedema (all causes) and able to give informed consent were included. End-of-life-patients or those judged as not in the patient's best interest were excluded. Both univariable and multivariable analysis were performed. RESULTS: A total of 2160 patients were included from Australia, Denmark, France, Ireland, Italy, Japan, Turkey and United Kingdom. Secondary lymphoedema was present in 98% of the patients; 95% of these were judged as related to cancer or its treatment. The lifetime prevalence of cellulitis was 22% and 1-year incidence 11%. Following multivariable analysis, factors associated with recent cellulitis were longer swelling duration and having poorly controlled lymphoedema. Compared to having lymphoedema less than 1 year, the risk increased with duration: 1-2 years (OR 2.15), 2-5 years (OR 2.86), 5-10 years (OR 3.15). Patients with well-controlled lymphoedema had a 46% lower risk of cellulitis (OR 0.54, 95% CI 0.39-0.73, p < 0.001). More advanced stages of lymphoedema were associated with cellulitis even after adjustment for swelling duration and control of swelling by logistic regression (stage II OR 5.44, stage III OR 9.13, p = 0.002), demonstrated in a subgroup analysis. CONCLUSION: Patients with advanced arm lymphoedema are at particular risk of developing cellulitis. Prevention of lymphoedema progression is crucial. The results lend towards a positive effect of having well-treated lymphoedema on the frequency of cellulitis.

Cytokines and Venous Leg Ulcer Healing-A Systematic Review.

Venous leg ulcers (VLUs) are the most common type of leg ulcers with a significant socioeconomic burden due to slow healing. Cytokines may be involved in the pathogenesis of VLUs. In this systematic review, our objective was to investigate the association between cytokine levels, including growth factors, with the healing of VLUs. PubMed, Embase, Web of Science and Cochrane Library were searched from their inception to August 2021. We retrieved 28 articles investigating 38 different cytokines in 790 patients. Cytokines were most commonly investigated in wound fluid and less frequently in biopsies and serum. The studies were judged as having a moderate to high risk of bias, and the results were often inconsistent and sometimes conflicting. A meta-analysis was not performed due to clinical and methodological heterogeneities. We found weak evidence for elevated IL-1α, IL-6, IL-8, TNF-α and VEGF levels in non-healing VLUs, an elevation that declined with healing. TGF-ß1 levels tended to increase with VLU healing. Other cytokines warranting further investigations include EGF, FGF-2, GM-CSF, IL-1ß, IL-1Ra and PDGF-AA/PDGF-BB. We conclude that non-healing VLUs may be associated with an elevation of a palette of pro-inflammatory cytokines, possibly reflecting activated innate immunity in these wounds. There is a paucity of reliable longitudinal studies monitoring the dynamic changes in cytokine levels during wound healing.

"I Cry. I Simply Cry." An Ethnography of a Lymphedema Summer Camp.

Background: The aim of this study was to explore how self-management is taught, learnt, and experienced during a 3-day educational Lymphedema Camp for parents of children with lymphedema. Methods: Participants (professionals, parents, and children) were observed during camp activities and interviewed informally and formally in focus groups. The embodied nature of the experience expressed by professionals, parents, and researchers became the analytical focus for understanding the felt tensions in the teaching and learning of self-management to families. Findings: The affective sensibilities associated with the uncertainties involved in teaching and learning self-management skills were palpable given that: young people are now expected to take up strict time-consuming self-management regimens (often via the support of a parent) where "evidence-based" outcomes are uncertain or may not match the outcomes wanted by a young person (varying in age and therefore ability or willingness to engage); or where there are tensions within the family; and the variety of different professionals involved means that techniques varied but where these professionals also lacked the necessary skills training to guide them in how to teach self-management. An analytical focus on the distress, doubt, fear, loneliness, guilt, and moralism felt by professionals, parents, and the researchers supports us to identify the character of the problems associated with performing best practice care guidance where there is a lack of practical support or resources for how self-management in this population should be achieved. Conclusion: To avoid these issues more training and research are needed on "how" to self-manage and stop victim-blaming that generates tensions and drives a wedge between the carer and the cared-for. When systemic problems get located with individuals (professionals, parents, or children), this directs our attention and understanding away from systems of care that lack coordination, may be under-resourced, and where effective training is absent.

Development of Self-Efficacy Tools for Parents and Professionals Caring for Children and Young People with Lymphedema (ILF Parent SE and ILF Professional SE).

Background: Self-management is a key aspect of lymphedema treatment and self-efficacy is a key factor linked to long-term adherence to treatment. The study aimed to generate self-efficacy scales to support the care of children and adolescents with lymphedema to support self-management. Methods and Results: Parents of children with lymphedema and the professionals caring for them were recruited during a lymphedema educational camp. Six individual semistructured focus groups were undertaken in Italian, French, and English (three for parents and three for professionals) with simultaneous translation. Scale item generation was developed using interpretative phenomenological analysis and adopted Bandura's self-efficacy concept. Two self-efficacy tools were developed from research with 26 parents and 14 professionals. The parental tool (ILF parent SE) has 6 domains and 44 items: school; home and leisure; understanding the condition and treatment, and managing child and parent emotions. The professional tool (ILF Professional SE) has 4 domains and 21 items. This scale has two parts; the first indicates the level of professional autonomy in decision making, and the second covers assessment and treatment, patient understanding, and managing emotional reactions. Both tools adopt a 0- to 100-point scale using a 10-unit interval with 0 (cannot do) through to 100 (high certainty of being able to do). Initial face validity has been undertaken. Conclusion: Self-efficacy has emerged as a complex issue faced by parents and professionals involved with children and young people with lymphedema. By being able to assess the challenges parents face in self-efficacy individualized programs can be developed that will assist families in managing this complex disease and lead to greater well-being. Increased professional self-awareness will help the development of mentorship programs to support professionals dealing daily with the stress of managing a rare disease in which the outcome may be uncertain.

Factors Predicting Limb Volume Reduction Using Compression Bandaging Within Decongestive Lymphatic Therapy in Lymphedema: A Multicountry Prospective Study.

Objectives: To identify predictive factors associated with limb volume reduction using different decongestive lymphatic therapy (DLT) systems in patients with lymphoedema, over a period of up to 28 days. Methods: A multicountry (Canada, France, Germany, the United Kingdom) prospective cohort study using (DLT): skin care, exercise, compression bandaging, and manual lymphatic drainage for up to 4 weeks. Reduction in limb volume comparing DLT with (1) standard multilayer bandaging with inelastic material, and with (2) multilayer bandaging with Coban2, together with the identification of factors associated with limb volume changes. Results: Out of 264 patients with upper or lower limb lymphedema, 133 used Coban2 and 131 used standard care. Following DLT, mean limb volume reduction was 941 mL using Coban2 compared with 814 mL using standard care. A difference of 127 mL was found (95% confidence interval -275 to 529 mL, p = 0.53). Of the 176 patients with leg swelling, 166 (94.3%) had a limb volume measurement after 28 days and were included in the risk factor analysis. Of these, 132 (79.5%) were female, with overall mean age of 60.1 years (standard deviation = 14.7), with secondary lymphedema in 102/163 (62.6%). Duration of lymphedema was >10 years in 75/161 (46.6%) and 99/166 (59.7%) were International Society of Lymphology late-stage II/III, indicating longstanding and/or a high frequency of patients with advanced stages of lymphedema. Ninety-one (54.8%) received Coban2 and 75 (45.2%) had standard care. Multivariable factors for a greater leg volume reduction were large initial leg volume (p < 0.001), DLT treatment duration of 4 weeks compared with 2 weeks (p = 0.01), and peripheral arterial disease (p = 0.015). Conclusion: Limb volume changes were found to be similar between groups. Lack of standardization of DLT makes interpretation of effectiveness problematic. There is an urgent need for randomized-controlled trials. Despite this, severe lymphedema with a large limb volume responded well to DLT in this study.

LIMPRINT in Italy.

Background: To define the profile of patients presenting with chronic edema (CE) in three centers in Italy (Lymphoedema IMpact and PRevalence INTernational). Methods and Results: Data were collected in patients referred for CE between September 2016 and July 2017. A total of 1637 were recruited, 86.7% (1419) outpatients and 13.3% (218) inpatients with 80.6% (1319) female and mean age 54 years. Primary lymphedema occurred in 28.2% (461). In the 71.8% (1176) with secondary CE cancer occurred in 72% (846) and 28% (330) due to other causes. Data showed that 84.2% (226) had full upper body mobility, 15.5% (41) had limited mobility and 0.2% (2) had lost all mobility. Lower limb mobility status: 90.4% (1205) complete mobility, 8.4% (112) reduced mobility and 1.2% (21) wheelchair bound. Concurrent leg ulceration occurred in 32.9% (322) with 3.1% (51) having antibiotics. Treatment patterns varied with only 32.4% (530) receiving instructions in skin care, 61.2% (1002) multilayer compression and a further 67.8% (1110) compression garment with 17.6% (288) having sequential pressure therapy. Only 1.4% (23) had received psychological support. Out of the total 481/1637 (29.4%) were not prescribed any treatment. Only 50.4% (825) had access to subsidized treatments within the National and Regional Health Care System, whereas 49.6% (81) had to pay themselves with only half (50.9%) having access to treatment centers that were near their home. Conclusion: Results from this study and active lobbying have led to changes in reimbursement of care for primary and secondary lymphedema in Italy; this has led to a much more optimistic picture for those affected.

Global Knowledge Gaps in Equitable Delivery of Chronic Edema Care: A Political Economy Case Study Analysis.

Background: Most existing research in chronic edema (CO) care takes place in high-income countries and is both clinically and medically focused, although often accorded low prestige and status. A myriad of challenges define the problems and important gaps in understanding and translating what we know into sustainable practice. Less considered, however, are the consequences and socioeconomic significance of this "knowledge gap" in an increasingly globalized world. This article seeks to address this lacuna by suggesting a political economy approach across three different income settings, the United Kingdom (high), Kerala in India (middle), and Uganda (low), to learn from international practice and understand the contribution of local (community-specific) health traditions. Methods and Result: We used a comparative case study approach. In the three case studies we demonstrate how particular thinking, sets of power relationships, and resource distributions influence and structure the provision of CO management more generally. We demonstrate how these intertwined and often invisible processes reflect a market-led biomedical hierarchization that focuses on high-interventionist, high-cost approaches that are then imposed on lower income settings. At the same time, low-cost but evidence-based local knowledge innovation in wound and CO care from low- or middle-income countries is neither recognized nor valued. Conclusion: We conclude that unpacking these dynamics is a necessary route to providing a more equitable health delivery accessible for the many rather than the few.

Prevalence and Impact of Chronic Edema in Bariatric Patients: A LIMPRINT Study.

Background: Chronic edema (CO) is a complex condition, arising from different factors, including immobility and obesity. Edema and obesity can have a significant impact on quality of life of patients and their families. Understanding how to manage edema in obese patients is an increasing challenge for both patients and clinicians. As effective treatment options are limited for this population, it is more cost-effective for patients to lose weight before starting treatment. When patients cannot maintain weight loss, one option is to have bariatric surgery. This study was part of LIMPRINT: Lymphedema IMpact and PRevalence INTernational, a study with the aim of identifying the prevalence and impact of CO in different countries and health care settings. Study Purpose: To evaluate the prevalence and impact of CO among patients in a United Kingdom bariatric surgical service. Methods and Results: The gold standard pitting test assessed the presence of edema. General (EuroQOL-5 Dimensions [EQ-5D], RAND 36-Item Short Form Health Survey, Version 1.0 [SF-36], Generalized Anxiety Disorder 7-Item Scale [GAD-7] and Patient Health Questionnaire-9 [PHQ-9]), and edema-specific (Lymphedema Quality of Life [LYMQOL]) quality-of-life questionnaires were used to evaluate impact of edema. The prevalence of edema was 52.1% (25 of 48 participants had edema), potentially linked to obesity, immobility, and medications. Most participants had International Society of Lymphology (ISL) Stage I edema. There were no statistically significant differences between the quality of life of participants with and without edema. However, comparing SF-36 results and normative population data indicated that quality of life was much lower than those in the normative population. Conclusions: This study highlights the high prevalence of edema and low quality of life of this bariatric population. ClinicalTrials.gov ID: NCT03154593.

Association Between Access to Specialists and History of Cellulitis Among Patients with Lymphedema: Secondary Analysis Using the National LIMPRINT Database.

Background: Cellulitis is frequently encountered in patients with lymphedema despite existing prevention protocols. To resolve this issue, social aspects surrounding patients, such as communication with patients and professionals, are necessary to consider new approaches. This study aimed to clarify the association between the history of cellulitis in patients with lymphedema and access to specialists after adjustment for relevant confounding factors. Methods and Results: This study was a secondary analysis of the Lymphoedema IMpact and PRevalence-INTernational (LIMPRINT) study using a national Japanese database of adult lymphedema compiled between 2014 and 2015 (n = 113). Descriptive data were collected for patient characteristics. Multivariate logistic regression analysis was conducted to explore possible risk factors for patients having experienced cellulitis. The duration of edema ranged from <6 months (16.2%) to 10 years or longer (25.2%), with varying severity. History of cellulitis was observed in 31.9% of patients. The prevalent treatment techniques within the context of complex decongestive therapy included skin care advice (52.2%), compression garments (55.8%), exercise advice (41.6%), multilayer bandages (38.1%), cellulitis advice (49.6%), and massage (61.1%). Overall, 57.1% of patients had access to lymphedema specialists. Longer duration of lymphedema (adjusted odds ratio [AOR] = 4.10, p = 0.005) and access to lymphedema specialists (AOR = 0.28, p = 0.009) were significantly associated with a history of cellulitis. Conclusions: A history of cellulitis in patients with lymphedema is associated with limited access to specialists. To support self-care in this patient population, reasonable consideration systems, including telehealth, should be developed to facilitate communication between specialists and patients and decrease the occurrence of cellulitis in lymphedema.

Quality of Life and Costs Within Decongestive Lymphatic Therapy in Patients with Leg Lymphedema: A Multicountry, Open-Label, Prospective Study.

Background: Little is known of the impact in terms of health-related quality of life (HRQoL) and cost-effectiveness with decongestive therapy. Objectives: To examine changes in limb volume, quality of life (QoL), and treatment cost of methods of decongestive lymphatic therapy (DLT). Methods: Patients with chronic edema/lymphedema of the leg were invited to participate in a study of DLT in four countries (United Kingdom, France, Germany, and Canada). In each country two sites were selected. One site used their standard method of DLT in their service, including compression with multilayer bandaging with inelastic material. The other site used a system that included 3M™ Coban 2™ as the bandage treatment alongside other standard components of DLT. Patients were followed for either 2 or 4 weeks depending on the local protocols. At entry, at 2 weeks, and at 4 weeks, patients were assessed by using a health index (EQ-5D), a disease-specific HRQoL tool (LYMQOL) and resource usage was recorded over the treatment period. Results: Of the 165 patients with cost data, 90 were treated with Coban 2 and 75 with standard care compression bandaging. There was good evidence of an improvement in EQ-5D of 0.077 (p < 0.001) in all patients. LYMQOL showed significant improvements (p < 0.001) with lower scores. There were no major differences between the two arms of the study with respect to HRQoL. The number of treatment episodes was higher in those treated with standard care (8.15 vs. 6.37), but the overall treatment cost was higher with Coban 2 (£890.7) compared with standard care (£723.0). Conclusion: QoL improved in the standard care and Coban 2 group bandages, and there was no demonstrable difference between the care systems. Further work is required to examine the role of the individual parts of DLT that provide the greatest benefit to patients and the health systems that support them.

Communication with patients using negative wound pressure therapy and their adherence to treatment.

OBJECTIVE: The purpose of this study was to explore the challenges of communication between patients and health professionals, and patient adherence to treatment for hard-to-heal wounds when using negative wound pressure therapy (NPWT). METHODS: Face-to-face, semi-structured interviews were conducted with patients undergoing NPWT. Specific features of the NPWT device were the priority for discussion although other factors central to communication and adherence were also explored. RESULTS: A total of 24 patients took part in the study. Data saturation was achieved during the analysis. Patients required ongoing support to understand complex and often protracted treatment and this was particularly important when specialist technology was used. A distinction was highlighted between those who decided not to adhere with therapy and those who did so unintentionally. Participants faced difficulties in their communications with health professionals and in ensuring their needs were listened to and addressed. CONCLUSION: Further research is needed to achieve a better understanding of this distinction and to evaluate interventions which can sustain adherence behaviours. Further exploration of how to establish concordant patient/health professional communications is warranted.

Prevalence and Risk Factors for Chronic Edema in U.K. Community Nursing Services.

Background and Study Design: Chronic edema (CO) is believed to be a major clinical problem within community nursing services in the United Kingdom. This study was undertaken as part of the LIMPRINT international study to determine the number of people with CO and its impact on health services. Methods and Results: Three urban-based community nursing services participated in the United Kingdom with prospective evaluation for 4 weeks of all patients receiving nursing care using a questionnaire-based interview and clinical assessment using the LIMPRINT tools. Of the total 2541 patients assessed, 1440 (56.7%) were considered to have CO, comprising Leicester City [768/1298 (59.2%)], Nottingham West [124/181 (68.5%)], and Nottingham City [548/1062 (51.6%)]. The mean age for women with CO was 78.6 (standard deviation [SD] 12.8) years and that for men with CO was 72.9 (SD 14.5). More patients with CO suffered from diabetes (32.1% vs. 27.9%, p = 0.027), heart failure/ischemic heart disease (27.3% vs. 14.0%, p < 0.001), and peripheral arterial occlusive disease (5.5% vs. 1.9%, p < 0.001). By far the greatest association was with the presence of a wound (73.6% vs. 37.9%, p < 0.001). Cellulitis affected 628 patients (24.7%) and 688 patients (47.8%) had a concurrent leg ulcer. Rates of reduced mobility (71.6% vs. 61.9%) and obesity were higher in those with CO. Six independent factors associated with CO were service location, age, ethnicity, obesity, heart failure, and the presence of a wound. Conclusion: CO is a major and growing health care problem within primary care that has been previously unrecognized and requires effective service provision.

Clinical and Ethical Challenges in Undertaking LIMPRINT in Vulnerable Populations.

Background and Study Objective: To estimate the prevalence of chronic edema (CO) and wounds within two vulnerable populations, a male high security prison in the East Midlands (United Kingdom) and residential and nursing homes in the United Kingdom and Australia. Methods and Results: Methods for screening for CO and wounds were adapted from the main LIMPRINT methodology. Prison Population: In total, 195 inmates were recruited with 22 (11%) having CO. While the majority were white Caucasian (156/83.4%) a further 20 (10.7%) were dark skinned with 11 (5.95%) from other minority populations. Comorbidities included 123 (63%) smokers, 22 (11%) alcohol dependant, 60 (31%) with mental health problems, and 35 (18%) a history of self-harm. Only three had a current wound with 30 (16%) having had a traumatic stab wound. Residential and Nursing Homes (United Kingdom and Australia): In the United Kingdom, the total population available for inclusion was 189 with only 137 (73%) recruited. Seventy-two of the 137 (52%) suffered from CO and a further 16 (23%) had a history of cellulitis. Results from the Australian residential care facilities have been published in full. In summary, of the 37 participants 20 (54%) experienced CO with 25 (68%) having comorbidities and 11 (30%) having a concurrent wound. Conclusion: Obtaining an accurate picture of the prevalence and impact of CO in vulnerable populations is extremely challenging due to issues of access and consent. Lack of reliable data for these populations will contribute to poor service provision.

LIMPRINT: Estimation of the Prevalence of Lymphoedema/Chronic Oedema in Acute Hospital in In-Patients.

Background: To estimate the prevalence of lymphedema/chronic edema (CO) and wounds in acute hospital inpatients in five different countries. Methods and Results: A point-prevalence study was carried out during working day periods in six general hospitals in four countries (Denmark, France, United Kingdom, and Australia) and one hospital oncology inpatient unit in one other country (Ireland). The study used validated clinical tools for the assessment and collection of data. Data were collected by expert clinicians through interviews and physical examination of the patients present in the wards. A total of 1905 patients could be included and investigated among the 3041 total bed occupancy in the seven hospitals. Lymphedema/CO was present in 723 of them (38%). Main risk factors associated with CO were age, morbid obesity, and heart failure, as well as chair bound immobility and neurological deficiency. History of cellulitis was frequent in patients with CO and wounds (24.8%) and CO alone (14.1%) compared to the 1.5% prevalence in patients without CO. Conclusion: Lymphedema/CO is very frequent in patients hospitalized in hospital acute wards. It is strongly associated with obesity, venous insufficiency, and heart failure. Our results strongly suggest a hidden health care burden and cost linked to CO independently of chronic wounds.

LIMPRINT: Prevalence of Chronic Edema in Health Services in Copenhagen, Denmark.

Background: The International Lymphedema Framework developed an international study, Lymphedema Impact and Prevalence International (LIMPRINT), to estimate the prevalence and impact of chronic edema (CO) in heterogeneous populations. Methods and Results: A validation study using the LIMPRINT methodology was undertaken in Denmark. Participants with CO were identified from inpatient services and compared with those identified within a specialist lymphedema service and three primary care settings. Of 452 inpatients available for screening, CO was present in 177 (39%) and absent in 275 (61%). In addition, 723 participants were found from specialist and primary care services (LPCSs). Inpatients were significantly older and more likely to be underweight or normal weight. They were more likely to suffer from heart failure/ischaemic heart disease (44.6% vs. 23.4%, p < 0.001) and have neurological problems (18.1% vs. 10.9% p = 0.009). Patients in the inpatient group were nearly all suffering from secondary lymphedema and were less likely to have a cancer or venous diagnosis, but more likely to have immobility as the cause of CO (44.0% vs. 17.7%, p < 0.001). No inpatients had midline CO compared with 30 within LPCSs. Fewer in the inpatient group had standard CO treatment (17.1% vs. 73.5%, p < 0.001) and subjective control of swelling was worse (19.9% vs. 66.7%, p < 0.001). While the inpatient group experienced fewer acute infections, when they did so, they were more likely to be admitted to hospital for this (78.6% vs. 51.0%, p = 0.049). Conclusion: The prevalence of CO in inpatient facilities is high and those with CO have multiple comorbidities that vary according to setting. The feasibility study showed that the methodology could be adapted for use in different health systems.

LIMPRINT: The UK Experience-Subjective Control of Swelling in Patients Attending Specialist Lymphedema Services.

Background and Study Design: This study was undertaken as part of the UK LIMPRINT international study to determine the number of people with chronic edema (CO) and its impact on health services. Overall 7436 with CO were recruited in the main UK study from a range of health settings. Methods and Results: Factors relating to subjective control of arm and leg CO were defined in the UK. A total of 1565 patients were included in the study with exclusions for: no limb swelling or not recorded (1669), having concurrent arm/leg CO (272), control of assessment missing (5) and professional being unsure of control status of CO (325). Arm swelling occurred in 953 (18.5%) with leg CO in 4212 (81.5%). Poor control was found in 1430 (27.2%) and good control in 3735 (72.3%). Control of arm swelling was worse in men and control increased overall in those aged over 45 years. In contrast control of CO worsened in those with leg CO with increasing age and multiple co-morbidities. Obesity and cellulitis, particularly an episode in the last year were associated with poor control. Independent risk factors for arm CO were : obesity, neurological disease and cellulitis in the last year and for leg CO, obesity, poor mobility, heart disease, presence of a wound, cellulitis in the last year and duration of swelling. Conclusion: Control of CO within specialized centers is complex due to sociodemographic and clinical comorbidities.

Community-Based Treatment for Chronic Edema: An Effective Service Model.

BACKGROUND: Chronic edema care is patchy and of variable quality internationally. This study was undertaken to develop and evaluate a system of care that would provide for patients within a geographical area of London (Wandsworth), United Kingdom. METHODS AND RESULTS: A prospective cohort design with intervention of a new service design following a 6-month baseline period. Patients were identified through health professionals. A stratified random sample was drawn from all patients and an implementation strategy developed. Clinical assessment combined with questionnaires evaluated clinical, patient, and health service outcomes at 6-month periods. In all, 312 patients were identified in community and acute services giving a crude ascertainment rate of 1.16 per 1000 population. The random sample of 107 was mostly female (82%) with mean (standard deviation) age of 72.9 (12.4) in men and 68.6 (15.0) years in women. Mean reductions in limb volume achieved statistical differences at 6-12 months after implementation (difference [d] = 115 mL, p = 0.0001). Incidence of cellulitis dropped from 41.5/100 patient years at baseline to zero at 6-12 months. Quality of life showed greatest improvements between baseline and 6 months postimplementation, the largest differences being in role physical (d = 32.7, p = 0.0001) and role emotion (d = 24.0, p < 0.0001). EuroQol increased following implementation by a mean score of 0.05 (p = 0.007). There was a reduction in 6 monthly healthcare costs from £50171 per 100 patients at baseline to £17618 between 6 and 12 months. CONCLUSIONS: This process of implementation improves health outcomes while reducing healthcare costs in patients with lymphedema.

Psychological Factors in Chronic Edema: A Case-Control Study.

BACKGROUND: To examine psychological health and perceived social support in patients with chronic edema (CE). METHODS AND RESULTS: A random sample of 107 patients with CE was group matched for age and gender with 102 community controls. The cases had swelling of the arm (38%) and leg (61%) and midline swelling (14%). Cases were more likely to be single or divorced/separated (p = 0.041) and have reduced mobility (p < 0.001). They had significantly poorer overall health related quality of life (HRQoL), in particular physical functioning (p = 0.003); role physical (p < 0.001); general health (p = 0.026); vitality (p = 0.015); social function (p = 0.007); and role emotional (p = 0.041). EQ5-D health index scores were significantly reduced in cases by 13 points (p = <0.001, 95% confidence interval 5.8, 21.6). Cases had similar sized social networks to the control group (5.8 vs. 6.6 p = 0.49), but had lower total perceived social support scores (67.8 vs. 76.1 p = 0.018). CE patients used significantly fewer coping strategies (COPE scale) than controls with regard to the following: active coping (p = 0.024); planning (p < 0.001); and use of instrumental support (p = 0.006). Significantly higher levels of coping were used in restraint (p = 0.031), positive reinterpretation and growth (p < 0.001); acceptance (<0.001); denial (p < 0.001); mental disengagement (p < 0.001); behavioral disengagement (<0.001); substance abuse (p = 0.010); and humor (p < 0.001). CONCLUSIONS: Patients with CE have poorer health and greater impact on many aspects of HRQoL. Perceived social support is reduced. Deficits in social function combined with perceived reduction in support, and reduced mental health and emotional scores indicate the risk of psychological issues. Systems of care should offer an environment to address these issues.

Chronic oedema: a prevalent health care problem for UK health services.

Chronic oedema (CO) is a major clinical problem worldwide, which has many important secondary consequences for health, activity and participation. Effective treatment planning and organisation of services is dependent on an understanding of the condition and its epidemiology. This cross-sectional study was designed to estimate the point prevalence of CO within the health services of one UK urban population and to determine the proportions that have concurrent leg ulceration. Patients with CO in all anatomic sites were ascertained by health care professionals in one acute and one community hospital, all relevant outpatient and community nursing services, general practices and all nursing/residential homes in one urban catchment area (Derby City). The presence and distribution of oedema was confirmed through a brief clinical examination. A battery of demographic and clinical details was recorded for each case. Within the study population of Derby City residents, 971 patients were identified with CO [estimated crude prevalence 3·93 per 1000, 95% confidence interval (CI) 3·69-4·19]. The prevalence was the highest among those aged 85 or above (28·75 per 1000) and was higher among women (5·37 per 1000) than men (2·48 per 1000). The prevalence among hospital inpatients was 28·5%. Only five (3%) patients in the community population had oedema related to cancer or cancer treatment. Of the 304 patients identified with oedema from the Derby hospitals or community health services, 121 (40%) had a concurrent leg ulcer. Prevalence statistics and current demographic trends indicate that CO is a major and growing health care problem.
