Epidemiology and health care situation of chronic wounds in Germany

Chronic wounds are of great socioeconomic importance. Usually they are associated with a long, complicated and burdensome course of disease and require high nursing and medical expenses. The quality of life of patients with chronic wounds is substantially impaired. This article provides a systematic overview of current studies on the morbidity and the health care situation of patients with chronic wounds, especially in patients with leg ulcers in Germany.

Analyses based on routine data of statutory health insurances show higher incidence and prevalence rates, for example of patients with leg ulcers, compared with previously regional surveys. The quality of care is inadequate, particularly in diagnostics and therapy of patients with leg ulcers. To date, there is undersupply and a lack of execution and deficient knowledge about the compression treatment in patients with venous leg ulcers.

Thus, there is need for further action in order to establish better implementation of guidelines in the management of patients with chronic wounds.

Demonstrating a Conceptual Framework to Provide Efficient Wound Management Service for a Wound Care Center in a Tertiary Hospital

Although the benefits of wound care services and multidisciplinary team care have been well elaborated on in the literature, there is a gap in the actual practice of wound care and the establishment of an efficient referral system. The conceptual framework for establishing efficient wound management services requires elucidation.A wound care center was established in a tertiary hospital in 2010, staffed by an integrated multidisciplinary team including plastic surgeons, a full-time coordinator, a physical therapist, occupational therapists, and other physician specialists. Referral patients were efficiently managed following a conceptual framework for wound care. This efficient wound management service consists of 3 steps: patient entry and onsite immediate wound debridement, wound re-evaluation, and individual wound bed preparation plan. Wound conditions were documented annually over 4 consecutive years.From January 2011 to December 2014, 1103 patients were recruited from outpatient clinics or inpatient consultations for the 3-step wound management service. Of these, 62% of patients achieved healing or improvement in wounds, 13% of patients experienced no change, and 25% of patients failed to follow-up. The outcome of wound treatment varied by wound type. Sixty-nine percent of diabetic foot ulcer patients were significantly healed or improved. In contrast, pressure ulcers were the most poorly healed wound type, with only 55% of patients achieving significantly healed or improved wounds.The 3-step wound management service in the wound care center efficiently provided onsite screening, timely debridement, and multidisciplinary team care. Patients could schedule appointments instead of waiting indefinitely for care. Further wound condition follow-up, education, and prevention were also continually provided.

[Wound networks in Germany: structure, functions and objectives 2014]

BACKGROUND

Wound networks are structured collaborations between various professions and medical disciplines in the field of treatment of patients with chronic wounds. In view of the complex chronic courses of such wounds with many relevant underlying diseases, comorbidities and a multitude of possible therapy options, the evidence-based structured treatment of patients with wound problems is of particular importance. However, this treatment is very heterogeneous and often uncoordinated.

OBJECTIVE

This article describes a stocktaking of the active regional wound networks in Germany with characterization of their structures, activities and objectives.

METHODS

A nationwide survey was carried out targeting wound specialists and wound societies as well as already established wound networks for which an updating was carried out. All identified networks were issued with a standardized questionnaire about the size of the network, extent of regional coverage, participating medical disciplines and professional groups and activities. In addition to the preformulated questions, free text information was also encouraged.

RESULTS

A total of 35 wound networks could be identified. The majority of networks consisted of representatives of hospitals as well as physicians in private practice and nursing personnel. The most frequently represented medical disciplines were vascular surgeons (74%), general physicians (63%), diabetologists (60%), general surgeons (60%) and dermatologists (57%). The most frequent activities were informal meetings on further education (77%), exchange of experiences and second opinions (both 71%) and consultation on patient treatment (69%). Selective contracts were only implemented in very few cases.

CONCLUSION

The wound networks established in Germany on self-initiatives represent strong interdisciplinary and interprofessional-oriented specialist platforms with a high potential for structured and efficient treatment. Incentives for systematic utilization of these structures in the course of improvements in quality and remuneration of treatment of patients with chronic wounds would be desirable.

Organization of wound healing services: The impact on lowering the diabetes foot amputation rate in a ten-year review and the importance of early debridement

Diabetes foot ulceration (DFU) has a negative impact on the quality of life and leads to disabling morbidity, such as lower extremity amputation (LEA). This study aimed to evaluate the LEA trend before and after the establishment of the diabetes foot team, an on-time debridement, on-site screening, and multidisciplinary integration with standardizing care, in Chang Gung Memorial Hospital, Chia Yi, Taiwan, starting in 2010. The study retrospectively investigated the non-traumatic LEA rate in diabetes foot (identified by using ICD-9-Clinical Modification (CM) codes, 250.70-250.83) and whole patients with diabetes (ICD-9 250.XX) yearly from 2004 to 2013. Patients were enrolled from hospitalization, emergency room (ER), or outpatient departments, respectively. Despite the overall incidence of diabetes foot in patients with diabetes remaining constant, from 3.47% in 2004 to 3.58% in 2013, the incidence of hospitalized diabetes foot from diabetes reduced, from 2.83% in 2004 to 1.51% in 2013. Introduction of integrated wound care also led to a reduction of the average LEA rate in hospitalized patients, from 15.27% (2004-2009) to 6.08% (2010-2013) (P<0.001). A similar decline of the LEA rate was observed for patients from hospitalization, ER and outpatient departments together with an average LEA rate from 7.99% (2004-2009) down to 3.02% (2010-2013) (P<0.001). In trend analysis, the curve estimation revealed a quadratic trend in the relationship between LEA rate and time (R-square=0.869, P=0.001) for hospitalized patients as well as a linear (R-square=0.819, P<0.001) and quadratic (R-square=0.845, P=0.001) trend in the relationship between LEA rate and time for hospitalization, ER, and outpatient departments together. The LEA rate for DM patients declined from 372.72/100,000 in 2004 to 61.74/100,000 in 2013. With establishment of an organizing, standardized wound care protocol and integrated multidisciplinary team, we demonstrated a significant decline in the LEA rate both in diabetes foot patients and all patients with diabetes. These improvements can be attributed to introducing an efficient pathway with on-time debridement and early intervention of diabetes foot ulcers.

Ulcer healing time and antibiotic treatment before and after the introduction of the Registry of Ulcer Treatment: an improvement project in a national quality registry in Sweden

OBJECTIVES

To investigate changes in ulcer healing time and antibiotic treatment in Sweden following the introduction of the Registry of Ulcer Treatment (RUT), a national quality registry, in 2009.

DESIGN

A statistical analysis of RUT data concerning the healing time and antibiotic treatment for patients with hard-to-heal ulcers in Sweden between 2009 and 2012.

SETTING

RUT is a national web-based quality registry used to capture areas of improvement in ulcer care and to structure wound management by registering patients with hard-to-heal leg, foot and pressure ulcers. Registration includes variables such as gender, age, diagnosis, healing time, antibiotic treatment, and ulcer duration and size.

POPULATION

Every patient with a hard-to-heal ulcer registered with RUT between 2009 and 2012 (n=1417) was included.

MAIN OUTCOME MEASURES

Statistical analyses were performed using Stata V.12.1. Healing time was assessed with the Kaplan-Meier analysis and adjustment was made for ulcer size. A log-rank test was used for equality of survivor functions.

RESULTS

According to the adjusted registry in December 2012, patients' median age was 80 years (mean 77.5 years, range 11-103 years). The median healing time for all ulcers, adjusted for ulcer size, was 146 days (21 weeks) in 2009 and 63 days (9 weeks) in 2012 (p=0.001). Considering all years between 2009 and 2012, antibiotic treatment for patients with hard-to-heal ulcers was reduced from 71% before registration to 29% after registration of ulcer healing (p=0.001).

CONCLUSIONS

Healing time and antibiotic treatment decreased significantly during 3 years after launch of RUT.

Quality of care in chronic leg ulcer in the community: introduction of quality indicators and a scoring system

BACKGROUND

Treatment of chronic wounds is complex, particularly as a standard for the assessment and evaluation of quality of care is missing.

OBJECTIVES

To develop indicators for quality of care in chronic wounds in general, and to evaluate the quality of care in leg ulcers in Hamburg, Germany, in particular.

METHODS

Twenty indicators were derived from a national Delphi expert consensus to compute a single index of quality of care. This index was applied in a cross-sectional study involving a large spectrum of care providers and leg ulcer patients in the community. Trained wound experts interviewed and examined the patients, who had to complete standardized questionnaires.

RESULTS

On average, 64% of the quality criteria were met in the consecutive sample of 502 patients with chronic leg ulcers of any origin; 75% of the patients were satisfied with their wound care. Predictors of quality of care are presented.

CONCLUSIONS

This instrument is feasible, valid and ready for comparisons of patient groups, regions and care systems, and for optimization processes in wound care.

In silico design of treatment strategies in wound healing and bone fracture healing

Wound and bone fracture healing are natural repair processes initiated by trauma. Over the last decade, many mathematical models have been established to investigate the healing processes in silico, in addition to ongoing experimental work. In recent days, the focus of the mathematical models has shifted from simulation of the healing process towards simulation of the impaired healing process and the in silico design of treatment strategies. This review describes the most important causes of failure of the wound and bone fracture healing processes and the experimental models and methods used to investigate and treat these impaired healing cases. Furthermore, the mathematical models that are described address these impaired healing cases and investigate various therapeutic scenarios in silico. Examples are provided to illustrate the potential of these in silico experiments. Finally, limitations of the models and the need for and ability of these models to capture patient specificity and variability are discussed.

Trends in surgical wound healing

The understanding of acute and chronic wound pathophysiology has progressed considerably over the past decades. Unfortunately, improvement in clinical practice has not followed suit, although new trends and developments have improved the outcome of wound treatment in many ways. This review focuses on promising clinical development in major wound problems in general and on postoperative infections in particular.

The Specialized Wound Care Center

Multidisciplinary wound care centers have proliferated as a result of an increasing need for care of nonhealing wounds. Information regarding types of wounds treated, length of treatment, compliance with treatment, and rates of healing was collected from a tertiary care hospital-based wound center over a 7-year period. Venous stasis ulcers were the most common type of wound treated (21%) and were also the most likely to heal. Pressure ulcers (20%), diabetic neuropathic ulcers (14%), ischemic ulcers (6%), and postsurgical wounds (6%) comprised the remainder of wounds treated. The success of treating wounds varied greatly with the wound's etiology. Despite the chronic nature of these wounds, most patients did not become long-term patients of the wound center. This study provides baseline outcome measures, which can serve as the basis for the comparison of treatment protocols and the development of prospective clinical trials.

Accurate diagnosis and effective treatment of leg ulcers reduce prevalence, care time and costs

OBJECTIVE

This long-term follow-up recorded the prevalence, aetiology and treatment of hard-to-heal leg and foot ulcers, and an estimated nurses' time spent providing care, for the years 1994-2005.

METHOD

A questionnaire was sent to all district and community nurses in the county of Blekinge, Sweden, during one week in 1994, 1998, 2004 and 2005. Calculating the costs of hard-to-heal leg and foot ulcer care was not a primary aim, but the reduction in prevalence and time spent on wound management suggested it was important to illustrate the economic consequences of these changes over time.

RESULTS

Estimated prevalence of hard-to-heal leg and foot ulcers reduced from 0.22% in 1994 to 0.15% in 2005. Treatment time decreased from 1.7 hours per patient per week in 1994 to 1.3 hours in 2005. Annual costs of leg and foot ulcer care reduced by SEK 6.96 million in the study area from 1994 to 2005.

CONCLUSION

Improved wound management was demonstrated; leg and foot ulcer prevalence and treatment time were reduced. The results could be attributed to an increased interest in leg and foot ulcer care among staff, which was maintained by repeated questionnaires, continuous education, establishment of a wound healing centre in primary care and wound management recommendations from a multidisciplinary group. The improved ulcer care reduced considerably the annual costs of wound management in the area.

Does the use of low-level laser influence wound healing in chronic venous leg ulcers?

OBJECTIVE

Venous leg ulcer treatment often requires months or years of regular wound care by trained staff. It has been suggested that low-level laser irradiation has a biostimulative and wound healing effect, but this has not been clinically verified by controlled studies. This study aimed to compare the effectiveness of low-level laser irradiation with that of a placebo 'light source'.

METHOD

Forty-four patients were assigned to two treatment groups (laser and placebo) or a third group (standardised treatment only) to quantify the effect of the laser therapy. Patients in all three groups received standardised wound care (disinfection, a hydrofibre dressing and compression bandaging). Ulcer size was measured at baseline (day 1), at the end of therapy (day 28) and then two months later (day 90). The relative difference in wound size was evaluated.

RESULTS

The difference in the reduction in wound size was not statistically significant in all three groups. A positive effect of using the non-laser device (placebo effect) was demonstrated in some patients.

CONCLUSION

These study results suggest that low-level laser does not stimulate wound healing in venous leg ulcers. Further controlled studies are needed to clarify the efficacy of low-level laser treatment as a wound-healing stimulant.
