Are ICD-10 codes appropriate for performance assessment in asthma and COPD in general practice? Results of a cross sectional observational study.

BACKGROUND: The increasing prevalence and impact of obstructive lung diseases and new insights, reflected in clinical guidelines, have led to concerns about the diagnosis and therapy of asthma and COPD in primary care. In Germany diagnoses written in medical records are used for reimbursement, which may influence physicians' documentation behaviour. For that reason it is unclear to what respect ICD-10 codes reflect the real problems of the patients in general practice. The aim of this study was to assess the appropriateness of the recorded diagnoses and to determine what diagnostic information is used to guide medical treatment. METHODS: All patients with lower airway symptoms (n = 857) who had attended six general practices between January and June 2003 were included into this cross sectional observational study. Patients were selected from the computerised medical record systems, focusing on ICD-10-codes concerning lower airway diseases (J20-J22, J40-J47, J98 and R05). The performed diagnostic procedures and actual medication for each identified patient were extracted manually. Then we examined the associations between recorded diagnoses, diagnostic procedures and prescribed treatment for asthma and COPD in general practice. RESULTS: Spirometry was used in 30% of the patients with a recorded diagnosis of asthma and in 58% of the patients with a recorded diagnosis of COPD. Logistic regression analysis showed an improved use of spirometry when inhaled corticosteroids were prescribed for asthma (OR = 5.2; CI 2.9-9.2) or COPD (OR = 4.7; CI 2.0-10.6). Spirometry was also used more often when sympathomimetics were prescribed (asthma: OR = 2.3; CI 1.2-4.2; COPD: OR = 4.1; CI 1.8-9.4). CONCLUSIONS: This study revealed that spirometry was used more often when corticosteroids or sympathomimetics were prescribed. The findings suggest that treatment was based on diagnostic test results rather than on recorded diagnoses. The documented ICD-10 codes may not always reflect the real status of the patients. Thus medical care for asthma and COPD in general practice may be better than initially found on the basis of recorded diagnoses, although further improvement of practice patterns in asthma and COPD is still necessary.

Initial nonresponders had an increased response rate after repeated questionnaire mailings.

BACKGROUND AND OBJECTIVE: There is a growing evidence base on methods to improve response rates in surveys among patients. This study aimed to determine the additional effect of two intensive follow-up procedures compared to a simple follow-up procedure. METHODS: Randomized controlled trial that compared repeated mailing of the questionnaire and a request to explain nonparticipation with a simple reminder card. The study population comprised 955 elderly adults registered with 26 general practitioners in The Netherlands. RESULTS: A total of 530 adults (56%) returned the questionnaire within 3 weeks and a total of 640 (67%) after follow-up. Repeated mailing of the questionnaire had additional effect compared to the simple reminder card in the group of initial nonresponders (relative risk=1.60, 95% confidence interval: 1.11-2.31), but not regarding the overall response rate. A request to explain nonparticipation did not have additional effect. CONCLUSION: Repeated mailing of the questionnaire increased the effectiveness of follow-up among initial nonresponders.

Guidelines on anaemia: effect on primary-care midwives in The Netherlands.

OBJECTIVE: To assess the adherence and perceived barriers for implementation of a clinical-practice guideline on anaemia, which was the first national guideline for primary-care midwifery in The Netherlands. DESIGN: Cross-sectional survey study. SETTING: Primary-care midwifery in The Netherlands. PARTICIPANTS: 160 midwives (60% response rate). MEASUREMENTS: Questionnaire on the knowledge of, and attitudes and self-reported adherence to, 14 key recommendations in the guideline; attitudes to guidelines in general; and perceived barriers to implementation. FINDINGS: The number of midwives agreeing with and adhering to specific recommendations varied between 29 and 90%. Most midwives had a positive attitude to the guidelines. The most relevant general barriers were related to the behaviour of general practitioners and obstetricians (32% of the midwives reported this). Larger numbers of midwives mentioned barriers to specific aspects of the guideline, particularly alternative iron supplementation or dietary supplements (59%), and not prescribing iron supplementation if haemoglobin was low but mean corpuscular volume was normal (49%). KEY CONCLUSIONS: The guideline on anaemia was well received by primary-care midwives in The Netherlands, but implementation of specific recommendations needs further attention. IMPLICATIONS FOR PRACTICE: The study provides evidence for the national organisation of midwives to continue with the development and implementation of clinical guidelines.

The OPTION scale: measuring the extent that clinicians involve patients in decision-making tasks.

OBJECTIVE: To examine the psychometric properties of a revised scale, named 'observing patient involvement in decision making' (OPTION), by analysing its reapplication to a sample of routine primary care consultations. The OPTION instrument assesses to what degree clinicians involve patients in decision making. DESIGN: Cross-sectional assessment of medical interaction by two calibrated raters. SETTING: Primary care. PARTICIPANTS: Twenty-one general practitioners provided 186 consultations for assessment. MEASUREMENTS: Observational score using the OPTION instrument. RESULTS: Compared with the first version of the OPTION scale, the revised scale that uses a magnitude instead of an attitude scale, when applied to the same data set, resulted in improvement in the scale's reliability and to lower scores for the levels of involvement achieved by the practitioners. Factor analysis confirms that it is acceptable to regard the scale as a single construct. Although there is moderate variability when raters are assessed on an item by item basis, the agreements between raters at the level of the overall OPTION score is high (the intraclass correlation coefficient scores for total OPTION score was 0.77), a level that is acceptable for the evaluation of a set of consultations per practitioner (e.g. between 5 and 10 consultations), where aggregate scores would be used for determining overall performance. CONCLUSIONS: We conclude that OPTION is sufficiently reliable to be used for formal assessment at the level of the whole instrument (all 12 items).

A consultation leaflet to improve an older patient's involvement in general practice care: a randomized trial.

OBJECTIVE: To evaluate the effects of a programme to enhance the involvement of older patients in their consultations in general practice. DESIGN: Cluster randomized trial, in which data was collected from different cohorts. SETTING AND PARTICIPANTS: Twenty-five general practices in the south-east part of the Netherlands and their patients aged 70 years and over. INTERVENTION: Patients in the intervention group received a leaflet to help them prepare for the consultation. General practitioners (GPs) received an outreach visit to optimize older patients' involvement when visiting their GP. Patients in the control group received usual care. MAIN OUTCOME MEASURES: Questionnaires measuring involvement (COMRADE), enablement (Patient Enablement Index) and satisfaction with their care (EUROPEP). RESULTS: Pre-intervention 315 patients and post-intervention 263 patients were included. Subjects were satisfied with their involvement and the GP's behaviour during the consultation. No differences in effect as a result of the leaflet on involvement, enablement or satisfaction were found between the intervention and the control group. Of 318 patients who received the leaflet and visited their GP in the intervention period, 47 patients used the leaflet. These users were more accustomed to prepare themselves for consultations. Users reported more psychological problems than non-users. CONCLUSIONS: No relevant effects of the implementation programme on involvement, enablement or satisfaction were found. Other strategies are needed to enhance involvement of older patients in their care. Alternatively, older patients may perceive themselves sufficiently involved.

Interventions to improve management of anxiety disorders in general practice: a systematic review.

BACKGROUND: Anxiety disorders are common in general practice and are associated with several problems regarding recognition and management. AIM: To systematically evaluate the effectiveness of interventions aimed at improving recognition, diagnosis, and management of patients with anxiety disorders. DESIGN OF STUDY: Systematic review. METHOD: MEDLINE, EMBASE, PsychINFO, and the Cochrane Clinical Trials' Register were searched up until 2003. Randomised controlled trials, controlled before/after trials, and interrupted time series for professional, organisational, financial, and regulatory interventions were eligible. Primary effect measures consisted of anxiety outcomes, diagnosis, prescription, and referral. Two reviewers independently made eligibility judgments: eight out of 563 articles were found to be eligible. Two reviewers participated independently in the quality assessment and data extraction process using a standardised form based on the Effective Practice and Organisation of Care checklist. Relative risks or standardised mean differences were calculated when possible. RESULTS: Four professional interventions and three organisational interventions were examined. In general, the professional interventions seemed to increase recognition, referral, and prescription as well as improving anxiety outcomes. Two out of three organisational interventions showed a positive effect on anxiety outcomes. The one study that took prescription into account showed no effect. CONCLUSIONS: The quality of care for patients with anxiety can be improved. A combination of professional and organisational interventions in which an external expert is introduced seems to be most promising. Additional research is nevertheless necessary to determine the exact effects of such interventions using patient effect measures, economic evaluations, and feasibility studies.

Effects of distance learning on clinical management of LUTS in primary care: a randomised trial.

AIM: To determine the effect of a distance learning programme on general practice management of men with lower urinary tract symptoms (LUTS). METHODS: A cluster randomised controlled trial was performed. General practitioners (GPs) were randomised to a distance learning programme accompanied with educational materials or to a control group only receiving mailed clinical guidelines on LUTS. Clinical management was considered as outcome. RESULTS: Sixty-three GPs registered care management of 187 patients older than 50 years attending the practice because of LUTS. The intervention group showed a lower referral rate to a urologist (OR: 0.08 (95% CI: 0.02-0.40)), but no effect on PSA testing or prescription of medication. PSA testing tended to be requested more frequently by intervention group GPs. Secondary analysis showed patients in the intervention group received more educational materials (OR: 75.6 (95% CI: 13.60-419.90)). CONCLUSIONS: The educational programme had impact on clinical management without changing PSA testing. Distance learning is an promising method for continuing education. PRACTICE IMPLICATIONS: Activating distance learning packages are a potentially effective method for improving professional performance. Emotional matters as PSA testing probably need a more complex approach.

What drives change? Barriers to and incentives for achieving evidence-based practice.

To bridge the gap between scientific evidence and patient care we need an in-depth understanding of the barriers and incentives to achieving change in practice. Various theories and models for change point to a multitude of factors that may affect the successful implementation of evidence. However, the evidence for their value in the field is still limited. When planning complex changes in practice, potential barriers at various levels need to be addressed. Planning needs to take into account the nature of the innovation; characteristics of the professionals and patients involved; and the social, organisational, economic and political context.

The effect of a distance-learning programme on patient self-management of Lower Urinary Tract Symptoms (LUTS) in general practice: a randomised controlled trial.

OBJECTIVE: To determine whether a distance-learning programme on LUTS provided to the general practitioner affected patient self-management. METHODS: A randomised trial was performed to examine the effects of the distance-learning programme (an educational package for the GP and a patient information leaflet) compared with written guidelines on LUTS mailed to the GP. In 63 general practices (32 intervention and 31 control) across the Netherlands all patients older than 50 years presenting LUTS for the first time were invited to participate. Main outcome measures were patient evaluation of quality of care received and perceptions of enablement. RESULTS: A total of 151 patients was included. The intervention increased patient enablement regarding maintenance of independence (OR = 3.14) and coping with illness (OR = 2.21). Overall enablement scores were not changed. Patients in the intervention group had more positive evaluations of general practice care received (OR = 2.28 to 3.95). An explorative analysis suggested that the effects of the intervention were mediated in particular by handing out of patient information leaflets. CONCLUSIONS: A distance-learning programme on LUTS for general practitioners had positive effects on patient self-management. Handing out leaflets appeared to be a crucial mediating factor.

Impact of national health care systems on patient evaluations of general practice in Europe.

OBJECTIVE: To examine associations between patient evaluations of general practice and characteristics of national health care systems. METHODS: International comparative study in 17 countries, using international patient survey data (n= 25052) and data-bases for health care system characteristics. Dependent variable was patients' evaluation of general practice care. Five independent factors were examined: GP density, physician density, fee for service reimbursement, gatekeeper role, and first-contact role. RESULTS: None of the associations were statistically significant. CONCLUSIONS: Patients were highly satisfied with general practice in different national health care systems. Descriptive tables on international variations may lead to misleading conclusions.

Health education on self-management and seeking health care in older adults: a randomised trial.

The aim of this randomised trial was to determine the effects of a health education strategy for older adults living at home on GP attendance. The health education comprised a written booklet on five frequently by GP unnoticed, highly prevalent and potentially treatable health problems: hearing impairment, visual impairment, urinary incontinence, depression and Lower Urinary Tract Symptoms (LUTS). The information comprised structured guidance to enhance decision-making on seeking health care by their GP and contained advice on self-management. The control group did not receive any intervention. Primary outcome was GP attendance of patients regarding the five health problems within 3 months. At this point we expected an increase of GP attendance. Six hundred and eighty-seven subjects completed the study. We can conclude that the health education strategy did not change the GP attendance of older adults. The results suggest that the health education was being appreciated as being useful and informative.

GPs' views on involvement of older patients: an European qualitative study.

Involvement of older patients in general practice care is regarded as important, but is not widespread. To determine specific barriers to the involvement of older patients in general practice care and to identify variations between countries, we performed an international comparative study based on qualitative interviews with 233 general practitioners (GPs) in 11 countries. Most GPs thought that involving older patients had positive outcomes. GPs saw patient involvement as a process taking place solely during consultations. The main barrier for GPs was lack of time. Barriers related to older patients were their feelings of respect for doctors, their lack of experience in being involved and possible mental and physical impairments. To conclude, increasing involvement of older patients is not easy and will only be effective when GPs have adopted a more developed concept of patient involvement and are supported with the different methods for achieving this. The range of appropriate interventions may be similar in all countries.

Use of prescribed and non-prescribed medication for dyspepsia.

OBJECTIVE: To explore patient factors related to the use of prescribed and non-prescribed drugs for dyspepsia in The Netherlands. DESIGN: Patient survey study. SETTING AND SUBJECTS: Questionnaires sent to patients who had a prescription for dyspepsia medication from their general practitioner. MAIN OUTCOME MEASURES: Patient factors related to the on-demand use of prescribed medication and the use of non-prescribed medication for dyspepsia. RESULTS: 74% of the (n=518) patients had been receiving prescribed medication for dyspepsia for more than one year. A quarter of the patients were using the prescribed medication "on demand" instead of adhering to the instructions on the prescription. PPI prescriptions reduced the probability of using the medication on demand, compared with other prescribed drugs (OR 0.39). Some 19% of the patients were using non-prescribed drugs for dyspepsia. More of the patients who had visited their general practitioner in the previous 12 months were using their drugs on demand (OR 2.27) and were using non-prescribed drugs (OR 2.40) than the patients who had not visited their GP. CONCLUSION: Clear information for patients on how to use their medication for dyspepsia may contribute to decreasing unnecessary drug use. Communication about (in)appropriate use of drugs "on demand", non-prescribed drugs, and health education should be addressed to all patient groups. Further studies on these topics should aim to improve medical care based on shared decision-making for patients with dyspepsia.

Quality circles to improve prescribing patterns in primary medical care: what is their actual impact?

RATIONALE, AIMS AND OBJECTIVES: Quality circles comprise small group sessions of doctors and written feedback on their individual practice patterns. Although 50% of German primary care doctors participate in quality circles, their effectiveness has hardly been evaluated in Germany. This study determined the impact of a large-scale programme of quality circles on quality and costs of prescribing. METHOD: A controlled before-after study was performed, in which primary care doctors were allocated to a quality circles group or a control group. Subjects were 100,000 patients in 1996 and in 1998, who had visited one of 177 doctors in the 3 month registration periods in one region in Germany. The intervention comprised a quality circles programme, comprising 11 sessions and repeated feedback on prescribing. Main outcome measures were proportion of patients who received a prescription, mean prescription costs per patient and proportion of generic prescriptions. RESULTS: The absolute numbers of prescriptions decreased in both groups, but the mean prescription costs per patient increased. The quality circles reduced the proportion of patients who received a prescription (OR = 0.86) and the mean prescription costs per patient (B = -3.99 euro), while it increased the proportion of generic drugs (OR = 1.10). The intervention had intended effects on four of the 15 secondary indicators. CONCLUSIONS: Large-scale application of quality circles had intended effects on prescribing decisions in primary care in Germany. The effects found in this study may reflect better what improvements can be achieved than randomized trials of similar interventions.

Shared care and the management of lower urinary tract symptoms.

OBJECTIVE: To investigate associations between the level of shared care and the clinical management of patients with uncomplicated lower urinary tract symptoms (LUTS). SUBJECTS AND METHODS: A cross-sectional survey study was conducted comprising all urologists and a random selection of general practitioners (GPs) in the Netherlands. Questionnaire responses were obtained from 182 urologists (70%) and 261 GPs (55%). The first part of the questionnaire established the physicians' characteristics and the second the level of familiarity with the national shared-care guidelines, arrangements between urologists and GPs, and the availability of a shared-care prostate clinic. The third part presented a written case of a 50-year-old man with clinical uncomplicated LUTS, and asked questions about diagnostic and therapeutic care. RESULTS: The clinical management of LUTS by GPs and urologists differed, particularly for diagnostic procedures. Only a minority of GPs (8%) and urologists (18%) had a shared-care clinic at their disposal. Such clinics were associated with an increase in tests ordered by the GP, e.g. creatinine levels (odds ratio, OR 3.83) and PSA levels (OR 5.93), and a decrease in choosing a watchful-waiting strategy for patients with mild symptoms (OR 0.24). Furthermore, urologists more often chose surgical intervention for moderate symptoms (OR 9.80). CONCLUSION: A shared-care clinic may lead to a shift in primary care towards the working style of urologists. This healthcare may not be as cost-effective as expected by policy makers. Prospective studies are needed to provide better insight in the health outcomes and efficiency of shared-care clinics.

Engaging general practitioners in the management of hazardous and harmful alcohol consumption: results of a meta-analysis.

OBJECTIVE: A systematic review was undertaken of studies that test the effectiveness of different strategies used to increase general practitioners' rates of screening for and giving advice about hazardous and harmful alcohol consumption. METHOD: Resources were MEDLINE, EMBASE, Cinahl and the Cochrane Library (1966-2001). Inclusion criteria were those of the Effective Practice and Organisation of Care Group of the Cochrane Collaboration. A meta-analysis was undertaken, using a random effects model, of 15 programs identified in 12 trials. Effect sizes, calculated using the logged odds ratio, were adjusted by inverse variance weights to control for the sample sizes of the studies. RESULTS: Analysis of the intervention groups resulted in screening and advice-giving rates of 45% (95% CI: 33%-56%) and analysis of the comparison groups resulted in rates of 32% (95% CI: 20%-43%). The weighted mean effect size (logged odds ratio = 0.73; 95% CI: 0.56-0.90) was heterogeneous. Regression analysis to explain the heterogeneity found a significant effect for alcohol-specific programs compared with general prevention programs in which alcohol was included, and for multicomponent programs compared with single component programs. No significant differences were found between educational-based or office-based interventions. CONCLUSIONS: Although the small numbers of programs studied suggest caution be used in interpreting the results, it seems it is possible to increase the engagement of general practitioners in screening and giving advice for hazardous and harmful alcohol consumption. Although considerably more research of high quality is needed, promising programs are those that have a specific focus on alcohol and those that are multicomponent.
