Measurement of healthcare quality in atopic dermatitis - development and application of a set of quality indicators.

BACKGROUND: Quality indicators are essential tools for the assessment of health care, in particular for guideline-based procedures. OBJECTIVE: Development of a set of indicators for the evaluation of process and outcomes quality in atopic dermatitis (AD) care. Application of the indicators to a cross-sectional study and creation of a global process quality index. METHODS: An expert committee consisting of 10 members of the German guideline group on AD condensed potential quality indicators to a final set of 5 outcomes quality and 12 process quality indicators using a Delphi panel. The outcomes quality and 7 resp. 8 process quality indicators were retrospectively applied to a nationwide study on 1678 patients with atopic dermatitis (AtopicHealth). Each individual process quality indicator score was then summed up to a global index (ranges from 0 [no quality achieved] to 100 [full quality achieved]) displaying the quality of health care. RESULTS: In total, the global process quality index revealed a median value of 62.5 and did not or only slightly correlate to outcomes quality indicators like the median SCORing Atopic Dermatitis (SCORAD; rp = 0.08), Dermatology Life Quality Index (DLQI; rp = 0.256) and Patient Benefit Index (PBI; rp = -0.151). CONCLUSION: Process quality of AD care is moderate to good. The healthcare process quality index does not substantially correlate to the health status of AD patients measured by 5 different outcomes quality indicators. Further research should include the investigation of reliability, responsiveness and feasibility of the proposed quality indicators for AD.

Quality of health care of atopic eczema in Germany: results of the national health care study AtopicHealth.

BACKGROUND: The successful treatment of atopic eczema (AE) should result in the improvement of both physical symptoms and patient's quality of life (QoL). This study was conducted using a sample of dermatologists throughout Germany. This is due to dermatologists being the main health care providers of AE. OBJECTIVES: Obtaining reliable data on quality of care of AE from both the patient's and the physician's perspective. METHODS: This cross-sectional study assessed: the individual clinical history; dermatology-specific QoL (DLQI); state of health (EQ-5d-VAS); treatments; burden caused by disease and treatment; patient-defined treatment benefit (PBI). RESULTS: Data from 1678 adult patients (60.5% female, mean age: 38.4 ± 15.9) were analysed. The most frequently used treatments during the last five years were emollients (90.4%) and topical corticosteroids (85.5%). In this study, 75.8% of the patients felt only moderately or not at all impaired by their treatment. The mean DLQI (0 = minimum-30 = maximum QoL impairment) was 8.5 ± 6.5. The EQ-5d-VAS (100 = best possible) was 63.6 ± 22.0 on average. 26.6% reported suffering 'often' or 'every night' from sleeplessness due to severe itching. Mean PBI was 2.4 ± 1.1 (4 = maximum benefit). CONCLUSIONS: This study provides first data on the health care of adults with AE in Germany at a national level and reveals the need for a more effective care. Whereas most patients consider their treatment-related burden as low, the daily burden of the disease seems to be high: one third reports sleeplessness due to itching which indicates insufficient therapeutic regimes in these cases. A better implementation of the German national guideline for AE and a systematic analysis of the difficulties causing its limited effects is needed.

A new instrument for the assessment of patient-defined benefit in the treatment of allergic rhinitis.

BACKGROUND: Allergic rhinitis (AR) is a common disease that affects health-related quality of life (HRQoL). Current and future health policy demands the assessment of patient-relevant treatment benefit for evaluation of treatments. METHODS: We developed, validated and tested a standardized instrument for the assessment of patient-relevant needs and benefits in AR. In an open survey of patients with AR, 100 need and benefit items were generated. The items were condensed to a 25-item list by an expert panel. On this list, patient rates the personal importance of 25 treatment needs on a scale ranging from 'not at all' to 'very' before treatment (Patient Needs Questionnaire, PNQ). At the end of the treatment, patient rates the extent, to which these needs were achieved by treatment from 'did not help at all' to 'helped a lot' (Patient Benefit Questionnaire). The patient benefit index (PBI) is computed to provide a global weighted benefit parameter. This disease-specific instrument was validated in n = 104 patients with AR. RESULTS: The PBI-AR showed good acceptability and feasibility in clinical routine. Reduction in nose and eye symptoms was rated most important. The PBI amounted to 2.2 (PBI ranges from 0 = 'no benefit' to 4 = 'maximum benefit'). Reliability of the PNQ was high (Cronbach's alpha = 0.9).The PBI was significantly correlated with relevant external validation criteria, such as patient satisfaction (R = 0.54) and HRQoL (R = 0.26). CONCLUSION: The PBI-AR is a feasible, reliable and valid instrument for the standardized assessment of patient-relevant benefits in the treatment of AR.

Prevalence of skin lesions and need for treatment in a cohort of 90 880 workers.

BACKGROUND: Healthcare planning requires robust data on the prevalence and need for care of dermatological diseases. To date, no systematic data in population-based samples are available for Germany. OBJECTIVES: Determination of the prevalence of skin lesions and of the need for care based on dermatological examinations in working adults in Germany. METHODS: From 2004 to 2009, workers aged between 16 and 70years from different branches of industry throughout Germany underwent a single dermatological whole-body examination on the occasion of company screening for skin cancer. The data were recorded electronically and evaluated descriptively. In addition to the clinical findings, case history data on previous skin diseases were documented and the need for further clarification or treatment was determined on the basis of the dermatologist's assessment. RESULTS: Data from n=90 880 persons from a total of 312 companies were evaluated. Of the pigmented skin lesions, dermal naevi were found in 25·1% of the cohort, and 16·7% displayed more than 40 each. The most frequent inflammatory skin diseases were acne vulgaris (3·9%), psoriasis (2·0%), rosacea (2·3%) and atopic eczema (1·3%). Examination of the case histories showed that the most frequent condition was allergic sensitizations (41·1%); of these, pollen accounted for the biggest group (21·4%), followed by contact allergens (8·0%). In total, 26·8% of the cohort exhibited a dermatological finding in need of treatment or further clarification. CONCLUSIONS: Dermatological lesions and diseases requiring clarification are frequent and indicate a high demand for treatment in the adult population.

Quality of life and satisfaction of patients with leg ulcers--results of a community-based study.

BACKGROUND: Leg ulcers have a major socio-economic impact because of their frequency and societal costs. Patients with leg ulcers experience major Health related Quality of Life (HrQoL) impairments. The aim of the present study was to assess the disease-specific HrQoL and the influence of care on HrQoL with leg ulcer. PATIENTS AND METHODS: A cross-sectional study was conducted in the metropolitan area of Hamburg to assess the quality of care as well as HrQoL in an unrestricted sample of patients with leg ulcers by questionnaires and subsequent clinical examinations. RESULTS: A total of 530 patients were consecutively recruited across all wound care provider sections in the metropolitan area of Hamburg. 53 % of the patients were highly or very satisfied with the health services provided. Significant correlations were found between the disease-specific HrQoL, patient satisfaction and satisfaction with wound treatment. Furthermore, significant predictors of HrQoL were: inadequate pain therapy, insurance status, wound size, time required for dressing changes and wound etiology. Most relevant predictors for satisfaction with health services were: HrQoL, duration of wound, health insurance status and treatment by office-based physicians. In contrast, no statistically significant association with HrQoL and satisfaction was found for gender, living district, education, number of dressing changes per week and the number of comorbidities. CONCLUSIONS: The results show that chronic leg ulceration has a major impact on patients HrQoL. Clinical and treatment characteristics, but not socio-demographic data, were predictors of HrQoL and satisfaction with health services. The systematic assessment of HrQoL in patients with leg ulcers across all sectors of health-care is a novum and provides important insights into the reality and quality of care.

Assessment of benefits and quality of medical healthcare treatment is becoming more and more important. In order to accurately carry out this assessment and to assure a reliable planning of health care, valid data are needed. Health services research is an interdisciplinary field of research, which provides information on disease and health care and to uncover suboptimal and incorrect services. This information can be used to improve the quality of treatment and to increase efficiency. In order to obtain information on the health care for skin and allergic diseases the German Center for Health Services in Dermatology (CVderm) was founded in 2005. It is actively involved in the coordination and conducation of health care, collaborating with other university groups.

Internet-supported gathering of treatment data and patient benefits in psoriasis.

BACKGROUND: Studies about health care of psoriasis patients in Germany are predominantly carried out in dermatological centres, which results in a certain selection bias. To collect data from other sources of patients, the German Centre of Health Services Research in Dermatology conducted a series of web-based studies. The extent of how data on health care on psoriasis gathered online vary from paper and pencil data is yet to be explored. OBJECTIVE: 1 To collect reliable treatment and benefit online data from psoriasis patients in Germany. 2 To compare these with data gathered at dermatological centres. METHODS: On the 'psoriasis-hilfe.de' web portal, psoriasis patients were asked to complete the online version of a questionnaire, which has already been used as a paper and pencil version in the national psoriasis study 'PsoHealth'. Subsequently, difference analyses were conducted between the two data sets. RESULTS: The PsoWeb sample (n = 1071) varies to a high extent from the PsoHealth sample (n = 2009) regarding the achievement of treatment goals and treatment satisfaction. Irrespective of age, sex and duration of disease, the online sample showed lower treatment satisfaction and fewer patient-defined benefits. CONCLUSION: The findings suggest that patients in the online sample are less satisfied with their health care, which also could have been their motive for participating online. It is important to gather data online because it increases the data pool and permits inclusion of people who are not incorporated in clinical settings. However, online data cannot directly replace data collected in clinics because they are also subject to selections.
