RESUMEN
AIM: To evaluate the effectiveness, feasibility and acceptability of a multicomponent intervention for improving personal continuity for older patients in general practice. DESIGN: A cluster randomised three-wedged, pragmatic trial during 18 months. SETTING: 32 general practices in the Netherlands. PARTICIPANTS: 221 general practitioners (GPs), practice assistants and other practice staff were included. Practices were instructed to include a random sample of 1050 patients aged 65 or older at baseline and 12-month follow-up. INTERVENTION: The intervention took place at practice level and included opTimise persOnal cOntinuity for oLder (TOOL)-kit: a toolbox containing 34 strategies to improve personal continuity. OUTCOMES: Data were collected at baseline and at six 3-monthly follow-up measurements. Primary outcome measure was experienced continuity of care at the patient level measured by the Nijmegen Continuity Questionnaire (NCQ) with subscales for personal continuity (GP knows me and GP shows commitment) and team/cross-boundary continuity at 12-month follow-up. Secondary outcomes were measured in GPs, practice assistants and other practice staff and included work stress and satisfaction and perceived level of personal continuity. In addition, a process evaluation was undertaken among GPs, practice assistants and other practice staff to assess the acceptability and feasibility of the intervention. RESULTS: No significant effect of the intervention was observed on NCQ subscales GP knows me (adjusted mean difference: 0.05 (95% CI -0.05 to 0.15), p=0.383), GP shows commitment (0.03 (95% CI -0.08 to 0.14), p=0.668) and team/cross-boundary (0.01 (95% CI -0.06 to 0.08), p=0.911). All secondary outcomes did not change significantly during follow-up. Process evaluation among GPs, practice assistants and other practice staff showed adequate acceptability of the intervention and partial implementation due to the COVID-19 pandemic and a high perceived workload. CONCLUSION: Although participants viewed TOOL-kit as a practical and accessible toolbox, it did not improve personal continuity as measured with the NCQ. The absence of an effect may be explained by the incomplete implementation of TOOL-kit into practice and the choice of general outcome measures instead of outcomes more specific for the intervention. TRIAL REGISTRATION NUMBER: International Clinical Trials registry Platform (ICTRP), trial NL8132 (URL: ICTRP Search Portal (who.int).

Polypharmacy is increasing with age. With increasing numbers of medication, the risk of the use of potential inappropriate medication is also increasing. In this article we suggest using the WHO-6-step for rational prescribing. We also describe methods and instruments (amongst others: the systemic tool to reduce inappropriate prescribing)physicians can use in assessing the appropriateness of the medication already used by their patients. Finally we describe how, based on recent Dutch guidelines, deprescribing can be done.

Oral and general health are inextricable. In primary care, the fields of care by general practioners, youth healthcare, healthcare for older people and oral care are all distinctly separated. Healthcare professionals are increasingly confronted with the complexity and increase in Noncommunicable diseases (NCD's) and an aging population. The aetiology of NCD's in primary care concern the professional fields of all healthcare professionals mentioned, meaning that lifestyle-related risks might be prevented more effectively through collaboration. In primary care, the number of medically compromised people is on the rise and healthcare professionals encounter each other's patients, whose risks remain invisible to them. Through collaboration such problems could be faced more effectively. Better integration of oral care into primary care can also contribute to the quality of care and safety of care receivers, and reduce further inequality. In order to better design this integration with the help of innovation, more practicebased research and implementation is needed.

When formulating recommendations, guideline developers have opportunities to use systematic reviews (SRs), which are widely considered to be the best available evidence. However, in practice the use of SRs by guideline developers is limited. Recent research has shown that only 22% (60/279) of the recommendations on screening of newborns for rare diseases were based on SRs. Moreover, the non-use of SRs was correlated with positive recommendations. This commentary discusses the reasons for limited SR use and the influence of wishful thinking on decision making. Although standards for guideline development are evolving, differing methods can still be used without compromising quality. Expert opinion is always needed to weigh the benefits and harms of the available management options. As long as potential conflicts of interest and considerations as well as choices made during the process are explicitly described, guidelines and policy decisions can be considered to be trustworthy.

The Health Council of the Netherlands has issued a report on the importance of extramural medical research. More attention is needed for diseases with high prevalence or a high disease burden, and results from intramural research cannot always be extrapolated to the primary care setting. Scientific research is crucial for developing and evaluating primary health care, so all general practitioners (GPs) should at least open their practices to data collection for scientific research purposes. Additionally, researchers from departments of general practice, together with healthcare professionals, should develop research questions that are in line with observed knowledge gaps in general practice. It is also important that university medical centres actively support research in primary care. A national primary care research agenda could contribute to the promotion of GP participation in scientific research in daily practice.

Research studies into the implementation of clinical practice guidelines often reveal only modest effects. These studies could have greater relevance if the following pitfalls were to be considered in advance. Firstly, there is a lack of awareness of the fact that physicians are overloaded with guidelines and need time for implementation, particularly when the guideline involves additional effort. Secondly, there is a lack of ownership of guidelines that were developed with involvement of many stakeholders. Thirdly, there is a lack of tailored implementation strategies focusing on specific recommendations rather than the whole guideline. Fourthly, guideline adherence is used as an outcome measure while there may be legitimate reasons to deviate from the guideline in individual cases. The future challenge for research into guideline implementation is to study how guidelines really could assist physicians in delivering personalised care.

BACKGROUND: Developing and updating high-quality guidelines requires substantial time and resources. To reduce duplication of effort and enhance efficiency, we developed a process for guideline adaptation and assessed initial perceptions of its feasibility and usefulness. METHODS: Based on preliminary developments and empirical studies, a series of meetings with guideline experts were organised to define a process for guideline adaptation (ADAPTE) and to develop a manual and a toolkit made available on a website (http://www.adapte.org). Potential users, guideline developers and implementers, were invited to register and to complete a questionnaire evaluating their perception about the proposed process. RESULTS: The ADAPTE process consists of three phases (set-up, adaptation, finalisation), 9 modules and 24 steps. The adaptation phase involves identifying specific clinical questions, searching for, retrieving and assessing available guidelines, and preparing the draft adapted guideline. Among 330 registered individuals (46 countries), 144 completed the questionnaire. A majority found the ADAPTE process clear (78%), comprehensive (69%) and feasible (60%), and the manual useful (79%). However, 21% found the ADAPTE process complex. 44% feared that they will not find appropriate and high-quality source guidelines. DISCUSSION: A comprehensive framework for guideline adaptation has been developed to meet the challenges of timely guideline development and implementation. The ADAPTE process generated important interest among guideline developers and implementers. The majority perceived the ADAPTE process to be feasible, useful and leading to improved methodological rigour and guideline quality. However, some de novo development might be needed if no high quality guideline exists for a given topic.

BACKGROUND: Evidence-based clinical guidelines aim to improve the quality of care. In The Netherlands, considerable time and effort have been invested in the development and implementation of evidence-based guidelines since the 1990s. Thus far, no reviews are available on their effectiveness. The primary aim of this article was to assess the evidence for the effectiveness of Dutch evidence-based clinical guidelines in improving the quality of care. METHODS: A systematic review of studies evaluating the effects of Dutch evidence-based guidelines on both the process and structure of care and patient outcomes was conducted. The electronic databases Medline and Embase (1990-2007) and relevant scientific journals were searched. Studies were only selected if they included a controlled trial, an interrupted time series design or a before and after design. RESULTS: A total of 20 studies were included. In 17 of 19 studies that measured the effects on the process or structure of care, significant improvements were reported. Thirteen of these studies reported improvement with respect to some of the recommendations studied. In addition, the size of the observed effects varied largely across the recommendations within guidelines. Six of nine studies that measured patient health outcomes showed significant but small improvements as a result of the use of clinical guidelines. CONCLUSIONS: This review demonstrates that Dutch evidence-based clinical guidelines can be effective in improving the process and structure of care. The effects of guidelines on patient health outcomes were studied far less and data are less convincing. The high level of variation in effects across recommendations suggests that implementation strategies tailored to individual recommendations within the guideline are needed to establish relevant improvements in healthcare. Moreover, the results highlight the need for well-designed studies focusing on the level of the recommendations to determine which factors influence guideline utilisation and improved patient outcomes.

BACKGROUND: Clinical practice guidelines are often evidence-based. However, it is inevitable that there are value judgements in the practical recommendations contained in the guidelines. In order to see if patients are ultimately being supplied with sufficient information to help them make treatment decision, we determined 1) which value judgements influence the process of developing guidelines for palliative chemotherapy, and 2) whether these value judgements were made explicit in the final guideline report. METHODS: We studied the development process of six Dutch oncology guidelines in which palliative chemotherapy plays a substantial role. We observed the guideline development groups (GDGs), conducted semi-structured interviews with individual GDG members (including the chairs), and analysed the minutes of GDG meetings and subsequent versions of the guidelines. A value judgement was defined as a statement about the value of a patient outcome with regard to palliative chemotherapy. RESULTS: We identified the following value judgements in the process of guideline development: 1) consensus on what should be considered as valuable minimum patient outcomes, 2) preference for tailored treatment in situations where there is no evidence of treatment effect, 3) preference for 'doing something' even when there is sufficient evidence of no effect, and 4) the patient outcome of 'prolonging life'. These value judgements, however, were not reported in the final guideline. CONCLUSION: At least the last two value judgements mentioned are relevant for patients with incurable metastatic cancer in making decisions whether to undergo chemotherapy and what kind. Value judgements should be made explicit in guidelines, so that clinicians can transparently discuss treatment options with individual patients.

--A national, multidisciplinary practice guideline was developed concerning diagnosis and treatment of patients with prostate cancer. Because of the lack of sufficient scientific evidence at this moment no practice guideline on screening is included. --The diagnosis of prostate cancer is made by transrectal ultrasound-guided prostate biopsies. The Gleason score is used for histological grading. --In localized prostate cancer and comorbidity 'active surveillance' is advised if the life expectancy is < 10 years. In healthy patients radical prostatectomy, external and internal radiotherapy are equivalent treatment options. The final decision is made after the patient has received adequate counselling. --In locally advanced prostate cancer in a patient with a life expectancy > or = 10 years external beam radiotherapy is the preferred treatment whether or not in combination with hormonal therapy. --In locally recurring prostate cancer following radical prostatectomy and prostate-specific antigen (PSA) < 1.0 ng/ml salvage radiotherapy can be advised. Recurrence following external beam radiotherapy may be treated by salvage radical prostatectomy or brachytherapy in selected cases. --In metastatic prostate cancer androgen deprivation therapy is advised, i.e. surgical castration, luteinizing hormone-releasing hormone (LH-RH) analogues, or parenteral estrogens. --In hormone resistant prostate cancer palliative treatment of painful metastases is advised, e.g. painkillers, local radiotherapy, or radionuclides. The role of docetaxel-based chemotherapy should be discussed. --During follow-up PSA is determined; digital rectal examination and imaging are performed whenever indicated.

The aim of the present study was to evaluate the implementation of the 2003 Dutch guideline on the diagnosis and treatment of malignant pleural effusions, and the potential effect of the implementation on the clinical outcome of pleurodesis. All patients with malignant pleural effusion who had a pleural drain placed with the intention of performing pleurodesis were registered prospectively in four centres. Details of the procedure and fluid recurrence and survival data were noted. Patients with a proven malignancy (n = 100) were entered into the registration database. Diagnostic guideline recommendations were followed in 60-70% of the patients. Surprisingly, pleurodesis was performed in only 75% of the patients, mainly due to the presence of a trapped lung. All pleurodeses were performed using talc, according to the guideline. Follow-up revealed fluid recurrence in 27 (36%) patients after a mean follow-up of 17 days (range 2-285 days); 14 patients with successful pleurodesis died with a median survival of 61 days (range 13-174 days). Systemic treatment following pleurodesis and good apposition of the pleural surfaces during drainage were good prognostic factors. Despite reasonable-to-good adherence to the guideline, the number of successful pleurodeses was low. Better predictors of a good pleurodesis outcome are needed.

BACKGROUND: The influence of a guideline on clinical practice depends on the extent to which the recommendations in the guideline are acted upon (degree of adherence). AIM: To assess the degree of adherence to recommendations in evidence-based guidelines and to discuss factors that influence adherence. METHOD: Review of the literature. results In several studies the average degree of adherence to recommendations in guidelines was no higher than 60 to 70%, but the percentage differed markedly, depending on the particular guidelines and the individual professionals involved. The degree of adherence was influenced by a large number of factors; these were connected with the guideline itself, the efforts made by the professional organisations, the organisation of care and institutional management, the individual professional, and the patient. The implementation of a guideline actually begins before and during the formulation of the guideline. Mistakes made in the preparatory phase can have a negative effect on adherence and often it may no longer be possible to correct these mistakes at a later stage. CONCLUSION: If the implementation is to be successful, numerous strategies have to be adopted along the way; for instance, the target-group has to be made aware of the guideline and be encouraged to accept it. Guideline development is not an aim in itself, but should be seen as part of a quality circle in which implementation and evaluation also play an important role.

OBJECTIVE: To examine the relationship between the number of procedures performed per hospital or per surgeon and health care outcomes. DESIGN: Literature review. METHOD: Relevant literature was identified using recent systematic reviews from Germany, England, France and the United States. The Cochrane Library, Medline and Embase were also searched for recent studies (2000-2005) published in German, English, French, or Dutch using the combined search terms 'surgery' and 'volume'; included studies reported mortality or morbidity as measures of health care quality. RESULTS: 5 systematic reviews were found, which described the results of a total of 41 relevant articles. 8 original articles of sufficient quality published since 2000 were also identified. Most of these articles were also included in the reviews. Relationships between volume per hospital and per surgeon and case fatality (or survival) and morbidity were found for a number of surgical procedures. The strongest associations between volume and case fatality were found for pancreatic and oesophageal resection and, to a lesser degree, elective repair ofabdominal aortic aneurysm. For other procedures the relationship was relatively weak, absent, or not studied. CONCLUSION: Volume appears to be related to quality for some surgical procedures. The magnitude of the relationship differs depending on the procedure. For technically less complex procedures, organisation within the hospital appears to have a greater influence on the differences between hospitals than the performing surgeon.

The aim of the clinical practice guideline 'Cardiovascular risk management' is an integral approach to all relevant risk factors for cardiovascular disease (CVD) caused by atherothrombosis. Patients with CVD, diabetes mellitus type 2 (DM2), elevated blood pressure or cholesterol, men of 50 years or older who smoke and women of 55 years or older who smoke are eligible for assessment of relevant risk factors for CVD. All high-risk patients should receive lifestyle counselling. In patients with CVD the use of acetylsalicylic acid and often, depending on the specific disease, a beta-blocker or an angiotensin converting enzyme (ACE) inhibitor are recommended. The use of a statin is recommended if the LDL-cholesterol concentration is > or = 2.5 mmol/l. In patients with DM2, the use of statins is recommended if LDL-cholesterol is > or = 2.5 mmol/l and use of a blood pressure lowering drug with a systolic blood pressure > or = 140 mmHg, as well as glucose lowering drugs. In patients without CVD and DM2, the need for drug treatment will be determined by estimation of the absolute 10-year mortality risk of CVD. Treatment is recommended if this risk exceeds 10%. The treatment and follow-up plan will be determined individually, depending on the risk profile, morbidity, comorbidity and patient's preferences.

A national, evidence-based guideline on the staging and treatment of patients with non-small cell lung carcinoma (NSCLC) has been compiled by the various disciplines involved. The initial diagnostic measures in patients with suspected lung cancer include history taking, physical examination and chest x-ray. Additional examinations include CT scan of the chest and upper abdomen, bronchoscopy, and 18F-fluorodeoxyglucose-positron-emission-tomography(FDG-PET)-scintigraphy, if curative therapy is planned. Cervical mediastinoscopy or endoscopic echography with fine needle aspiration can be performed for mediastinal tissue staging. The preferred treatment in stage I, II or limited III is radical resection. Postoperative radiotherapy is recommended in cases of incomplete resection and can be considered in patients in whom mediastinal lymph-node metastases are unexpectedly encountered. Chemoradiotherapy is recommended in locally advanced NSCLC. In patients with NSCLC stage I-III and poor performance status, palliative radiotherapy may be the only feasible treatment. Some patients with NSCLC stage III and stage IV can be offered palliative chemotherapy and supportive care. In cases of doubt about operability, resectability, significant pulmonary or cardiac comorbidity or combined treatment, a specialist centre should be consulted. Diagnostics should be completed within 3-5 weeks. Ensuing surgery or radiotherapy should be carried out within 2 weeks. Follow-up of patients with NSCLC includes history taking, physical examination and an optional chest x-ray. In the first year after treatment patient visits are planned quarterly, in the second year half-yearly and then yearly for at least five years.

In the Netherlands many institutes, associations and professional organisations are active in the development of guidelines for clinical practice. In 1997, the Dutch Cochrane Centre and the Dutch Institute for Healthcare Improvement (CBO) took the initiative and set up a national platform of guideline organisations (currently 28 in number) with the aim of harmonising methodology and promoting evidence-based guideline development. In 2003 the Guidelines International Network (G-I-N) was founded with similar goals but at international level. The Dutch platform (EBRO) offers the opportunity to establish a network that will plan and execute guideline development and updating. This will prevent duplication of efforts and controversy between stakeholders. Another task will be the promotion and transfer of knowledge on evidence-based guideline development by organising conferences and educational programmes. The ultimate goal is to support health-care providers in improving quality of patient care.

PURPOSE: To describe the quality of oncology guidelines developed in different countries. METHODS: The Appraisal of Guidelines and Research and Evaluation (AGREE) Instrument was used to assess the quality of 100 guidelines (including 32 oncology guidelines) from 13 countries. The criteria of the instrument are grouped into six quality domains: scope and purpose, stakeholder involvement, rigor of development, clarity and presentation, applicability, and editorial independence. RESULTS: Oncology guidelines had significantly higher scores on rigor of development than nononcology guidelines (42.2% v 29.4%; P =.02). In particular, systematic methods to search for evidence were more often used (P =.01); the methods for formulating the recommendations were more clearly described (P =.02); and health benefits, risks, and side effects were more often considered in formulating the recommendations (P =.03). Although the standardized scores for the other domains were not significantly different, the oncology guidelines had significantly higher scores for items measuring inclusion of all relevant professional groups (P =.05), consideration of patient views (P =.04), and presentation of different options (P =.05). Only three organizations producing oncology guidelines had standardized scores more than 60% for more than three domains. CONCLUSION: The quality of clinical practice guidelines (CPGs) is modest in general, but for certain domains, oncology guidelines seem to be of better quality than others. The experience of the organization may explain higher scores for some items. Research projects and training aimed at improving the quality of guidelines should be developed. The AGREE instrument could provide a basis for defining steps in a shared development approach to produce high-quality CPGs.
