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.

Longer-term changes in quality of life in chronic leg ulceration.

Studies that have examined patients' health-related quality of life have consistently shown improvements following intensive and effective treatments over relatively short follow-ups. However, little is known of the longer-term effects of treatment on patients. As part of a study in southwest London, United Kingdom, all patients having a current leg ulcer were examined (n = 113) and those who were able completed the Nottingham Health Profile (n = 95) and were then followed up at 24 and 48 weeks. The patients had a mean age of 76 +/- 13 (SD) years, with 60 (63.2%) being women. Before the study, the ulcer had been present for a median of 8 months (range 0.5-144), and a median area of ulceration of 4.0 cm2 (range 0.5-171.5 cm2). After 24 weeks, there was a significant improvement in pain (mean difference [d] = 9.6, p = 0.002), which was true for both the 41 patients with ulcers present (d=10.07, p = 0.013) and the 43 patients whose ulcers had healed (d = 11.46, p = 0.047). However, after 48 weeks, these improvements had been reduced in both groups (healed ulceration d = 5.76, unhealed patients d = 6.41). Energy, which had improved after 24 weeks in the patients whose ulcers, had healed (d = 11.46), deteriorated in both patient groups after 48 weeks (healed = -5.67, unhealed = -13.43). Mobility status was maintained with healed ulceration (d = 1.05) but deteriorated with unhealed ulceration (d = -13.19). The positive effects of treatment on health-related quality of life may not be sustained over time. This may be a consequence of the general deterioration in the health status of these elderly patients as they age.

Assessment of health-related quality of life in patients with lymphedema of the lower limb.

The purpose of this study was to examine the use of a number of tools in the evaluation of health-related quality of life in patients with lower limb lymphedema, and to determine the consequences of cancer history and concurrent leg ulceration. Patients in one health trust having lower limb lymphedema were identified and interviewed at entry and after 24 weeks. The short form-36 (SF-36), modified Barthel scale, McGill short form pain questionnaire, and Euroqol were administered at both time points. Of the 164 (median age=76.9 years, 70.7% women) patients who comprised the study population, 15.2% had a history of cancer and 30.4% had coexisting current leg ulceration. Internal consistencies were high for all scales (Cronbach's alpha >0.80). There were high ceiling effects for a number of SF-36 scores, and high floor effects in these and the McGill short form pain questionnaire, scales. Despite these limitations, there was strong evidence that treatment led to significant improvements in six of eight scores of the SF-36, three of three scores of the McGill short form pain questionnaire and the modified Barthel scale (all p<0.05). The improvement in physical functioning was significantly greater for patients who entered the study with a leg ulcer (mean different=9.1, 95% confidence interval 2.1-16.1, p=0.011). Patients treated with compression bandaging had significantly greater improvements for physical functioning (10.2) than those treated with compression hosiery (-1.5) or no treatment (-2.0), p=0.001. Of the tools assessed, the SF-36, appears to be the most appropriate for use in this patient group.

Illness behavior and social support in patients with chronic venous ulcers.

Venous ulcers are a chronic and costly condition for providers and payors, as well as for patients, particularly the elderly. To examine the association between chronic venous ulceration, illness behavior, and levels of social support, patients drawn from a separate clinical trial (N = 74) were interviewed using the Illness Behaviour Questionnaire and the Social Support Questionnaire. Results indicate that women had higher hypochondriasis (1.70 versus 1.03, P = 0.19), affective disturbance (2.70 versus 1.42, P = 0.08), and number of supports (Social Support Questionnaire, 2.41 versus 1.81, P = 0.056) than men, although no score achieved a standard level of statistical significance. Patients under 70 years of age had significantly higher hypochondriasis (1.96 versus 1.17, P = 0.021) and irritability (1.38 versus 0.90, P = 0.026) scores than those older than 70 years, although denial was significantly higher in those older than 70 years (3.97 versus 3.46, P = 0.045). The level of satisfaction with social support was significantly higher in those under 70 years of age (5.13 versus 4.97, P = 0.042). These results underscore the psychological and social cost imposed by chronic venous ulceration on older women. They also support previous studies implying a greater psychological burden on younger patients. The association between illness behavior and social support remains unclear, but examining the association between illness behavior and social support among patients with venous ulceration provides an opportunity to increase understanding of the psychological, physical, and social dynamics of this chronic condition.

Randomized trial of four-layer and two-layer bandage systems in the management of chronic venous ulceration.

To compare a four-layer bandage system with a two-layer system in the management of chronic venous leg ulceration, a prospective randomized open parallel groups trial was undertaken. In total, 112 patients newly presenting to leg ulcer services with chronic leg ulceration, screened to exclude the presence of arterial disease (ankle brachial pressure index <0.8) and causes of ulceration other than venous disease, were entered into the trial. Patients were randomized to receive either four-layer (Profore) or two-layer (Surepress) high-compression elastic bandage systems. In all, 109 out of 112 patients had at least one follow-up. After 24 weeks, 50 out of 57 (88%) patients randomized to the four-layer bandage system with follow-up had ulcer closure (full epithelialization) compared with 40 out of 52 (77%) on the two-layer bandage, hazard ratio = 1.18 (95% confidence interval 0.69-2.02), p = 0.55. After 12 weeks, 40 out of 57 (70%) patients randomized to the four-layer bandage system with follow-up had ulcer closure compared with 30 out of 52 (58%) on the two-layer bandage, odds ratio = 4.23 (95% confidence interval 1.29-13.86), p = 0.02. Withdrawal rates were significantly greater on the two-layer bandage (30 out of 54; 56%) compared with the four-layer bandage system (8 out of 58; 14%), p < 0.001, and the number of patients with at least one device-related adverse incident was significantly greater on the two-layer bandaging system (15 out of 54; 28%) compared with four-layer bandaging (5 out of 54; 9%), p = 0.01. The higher mean cost of treatment in the two-layer bandaging system arm over 24 weeks ($1374 [ pound 916] vs. $1314 [ pound 876]) was explained by the increased mean number of bandage changes (1.5 vs. 1.1 per week) with the two-layer system. In conclusion, the four-layer bandage offers advantages over the two-layer bandage in terms of reduced withdrawal from treatment, fewer adverse incidents, and lower treatment cost.
