Mortality in patients with Dupuytren's disease in the first 5 years after diagnosis: a population-based survival analysis.

Previous studies suggest that Dupuytren's disease is associated with increased mortality, but most studies failed to account for important confounders. In this population-based cohort study, general practitioners' (GP) data were linked to Statistics Netherlands to register all-cause and disease-specific mortality. Patients with Dupuytren's disease were identified using the corresponding diagnosis code and assessing free-text fields from GP consultations. Multiple imputations were performed to estimate missing values of covariates, followed by 1:7 propensity score matching to balance cases with controls on confounding factors. A frailty proportional hazard model was used to compare mortality between both groups. Out of 209,966 individuals, 2561 patients with Dupuytren's disease were identified and matched to at least four controls. After a median follow-up of 5 years, mortality was found to be actually reduced in patients with Dupuytren's disease. There was no difference in mortality secondary to cancer or cardiovascular disease. Future studies with longer average follow-up using longitudinal data should clarify these associations in the longer term.Level of evidence: III.

Women with unwanted pregnancies, their psychosocial problems, and contraceptive use in primary care in Northern Netherlands: insights from a primary care registry database.

INTRODUCTION: Globally an estimated 1 in 16 women per year experience an unwanted pregnancy (UWP). In the Netherlands, general practitioners (GPs) play an important role in providing care for women with UWP; however, it is unknown how many of these women consult their GP about the pregnancy. UWPs are a major life experience with a possible influence on mental health. Data that GPs register about UWPs, psychosocial problems, and contraceptive use could give more insight into care needs. AIMS: To create an overview of (i) the prevalence of UWPs in general practice, (ii) the prevalence of psychosocial problems in women with UWP, and (iii) contraceptive use of women with UWP. METHODS: GP registration data were analysed from 58 general practices located in Northern Netherlands between 2015 and 2019. Patient files were checked for registration of ICPC and ATC codes concerning pregnancy, psychosocial health, and contraceptive use. Chi-square and Fisher's exact test were used to calculate differences between women with a UWP and women with a wanted pregnancy (WP). An analysis of registration dates was conducted to determine when the psychosocial problems were registered in relation to the pregnancy. RESULTS: Of female patients of reproductive age, 1.6% had a UWP and 11.8% had a WP. Women with a UWP reported statistically significantly more psychosocial problems. Furthermore, statistically significantly more contraceptive methods were prescribed to women with UWP compared with both women with WP and women without pregnancy. DISCUSSION AND CONCLUSION: The finding that women with UWP experience more psychosocial problems can be used to improve aftercare and can be incorporated into current guidelines for GPs.

Primary care diagnostic and treatment pathways in Dutch women with urinary incontinence.

OBJECTIVE: To investigate how GPs manage women with urinary incontinence (UI) in the Netherlands and to assess whether this is in line with the relevant Dutch GP guideline. Because UI has been an underreported and undertreated problem for decades despite appropriate guidelines being created for general practitioners (GPs). DESIGN: Retrospective cohort study. SETTING: Routine primary care data for 2017 in the Netherlands. SUBJECTS: We included the primary care records of women aged 18-75 years with at least one contact registered for UI, and then extracted information about baseline characteristics, diagnosis, treatment, and referral to pelvic physiotherapy or secondary care. RESULTS: In total, 374 records were included for women aged 50.3 ± 15.1 years. GPs diagnosed 31.0%, 15.2%, and 15.0% women with stress, urgency, or mixed UI, respectively; no diagnosis of type was recorded in 40.4% of women. Urinalysis was the most frequently used diagnostic test (42.5%). Education was the most common treatment, offered by 17.9% of GPs; however, no treatment or referral was reported in 15.8% of cases. As many as 28.7% and 21.7% of women were referred to pelvic physiotherapy and secondary care, respectively. CONCLUSION: Female UI is most probably not managed in line with the relevant Dutch GP guideline. It is also notable that Dutch GPs often fail to report the type of UI, to use available diagnostic approaches, and to provide appropriate education. Moreover, GPs referred to specialists too often, especially for the management of urgency UI.Key pointsUrinary incontinence (UI) has been an underreported and undertreated problem for decades. Despite various guidelines, UI often lies outside the GPs comfort zone.•According to this study: general practitioners do not treat urinary incontinence according to guidelines.•The type of incontinence is frequently not reported and diagnostic approaches are not fully used.•We believe that increased awareness will help improve treatment and avoidable suffering.

Continuity of care and referral rate: challenges for the future of health care.

BACKGROUND: Continuity of care could reduce health care consumption by patients and reduce the number of referrals to specialist care, but it is unknown if there is a difference in referral rates to specific medical specialties. AIM: We aimed to determine the relationship between continuity of care and both the referral rate (referrals per patient per year) and the medical specialties for which this relationship was strongest. DESIGN AND SETTING: A retrospective cohort study of 19333 patients in primary care in the north of the Netherlands. METHOD: Patients with at least two contacts with a general practitioner (GP) over a 2-year period (2013-2014) were included. The number of contacts with their own or other GPs were calculated, and referral rates were determined. Continuity of care was included as a dichotomous variable (absent or present). RESULTS: The odds of being referred were higher for older patients, females and patients with more practitioner contacts. However, the presence of continuity of care was associated with the highest odds of referral. The referral rate was significantly highest for patients with continuity of care when referred to paediatrics, as well as for patients without continuity of care who were referred to gastroenterology, ophthalmology and psychiatry. CONCLUSION: Increased continuity of care decreases referral to specialist care, most notably for referrals to paediatrics. Despite continued pressures on continuity of care, policy makers should invest in this cornerstone of primary care to temper health care expenditures.

Possible missed opportunities for diagnosing colorectal cancer in Dutch primary care: a multimethods approach.

BACKGROUND: Early detection of colorectal cancer (CRC) is important to achieve better survival. Discriminating symptoms suggestive of CRC from benign conditions is a challenge for GPs because most known 'alarm symptoms' have low predictive values. AIM: To further understand the diagnostic process of CRC in general practice in terms of healthcare use and by analysing factors related to diagnostic intervals. DESIGN AND SETTING: A multimethod approach comprising a historical, prospective registry study and qualitative content analysis. METHOD: Healthcare use in the year before referral for colonoscopy was compared between patients diagnosed with CRC and an age-, sex,- and GP-matched control population. Qualitative content analysis was performed on free texts in electronic patient records from a purposive sample of patients with CRC. RESULTS: Patients with CRC (n = 287) had 41% (25-59%) more face-to-face contacts and 21% (7-37%) more medication prescriptions than controls (n = 828). Forty-six per cent of patients with CRC had two or more contacts for digestive reasons, compared with 12.2% of controls, more often for symptoms than diagnoses. From qualitative analysis two themes emerged: 'possible missed diagnostic opportunities' and 'improvements in diagnostic process unlikely'. Possible missed diagnostic opportunities were related to patients waiting before presenting symptoms, doctors attributing symptoms to comorbid conditions or medication use, or doctors sticking to an initial diagnosis. CONCLUSION: Fewer missed diagnostic opportunities might occur if GPs are aware of pitfalls in diagnosing CRC: the assumption that symptoms are caused by comorbid conditions or medication, or relating complaints to pre-existing medical conditions. GPs also need to be aware that repeated digestive complaints warrant rethinking an earlier diagnosis.

Application of the STOPP/START criteria to a medical record database.

PURPOSE: The STOPP/START criteria are increasingly used to assess prescribing quality in elderly patients at practice level. Our aim was to test computerized algorithms for applying these criteria to a medical record database. METHODS: STOPP/START criteria-based computerized algorithms were defined using Anatomical-Therapeutic-Chemical (ATC) codes for medication and International Classification of Primary Care (ICPC) codes for diagnoses. The algorithms were applied to a Dutch primary care database, including patients aged ≥65 years using ≥5 chronic drugs. We tested for associations with patient characteristics that have previously shown a relationship with the original STOPP/START criteria, using multivariate logistic regression models. RESULTS: Included were 1187 patients with a median age of 75 years. In total, 39 of the 62 STOPP and 18 of the 26 START criteria could be converted to a computerized algorithm. The main reasons for inapplicability were lack of information on the severity of a condition and insufficient covering of ICPC-codes. We confirmed a positive association between the occurrence of both the STOPP and the START criteria and the number of chronic drugs (adjusted OR ranging from 1.37, 95% CI 1.04-1.82 to 3.19, 95% CI 2.33-4.36) as well as the patient's age (adjusted OR for STOPP 1.30, 95% CI 1.01-1.67; for START 1.73, 95% CI 1.35-2.21), and also between female gender and the occurrence of STOPP criteria (adjusted OR 1.41, 95% CI 1.09-1.82). CONCLUSION: Sixty-five percent of the STOPP/START criteria could be applied with computerized algorithms to a medical record database with ATC-coded medication and ICPC-coded diagnoses.

Incidence and treatment of heavy menstrual bleeding in general practice.

Background: Heavy menstrual bleeding (HMB) is a common problem in women of reproductive age. In 2008, the Dutch guideline for general practitioners (GPs) was revised to recommend the levonorgestrel intrauterine system (LNG-IUS) as a first-choice treatment for HMB. However, GP prescribing practices have not been studied in depth. Objectives: To investigate the incidence and initial treatment of HMB in general practice, and to identify if there were changes in prescribing practices after the revision of the national guideline in 2008. Methods: Retrospective analysis of data from the Registration Network Groningen, the Netherlands. We selected data for prescriptions and referrals related to women consulting their GP for HMB between 2004 and 2013. We calculated the incidence rates and investigated potential trends in prescribing over time, with particular attention to the prescribing of LNG-IUS. Results: Over 10 years, 881 women consulted their GP for HMB, with a mean annual incidence of 9.3 per 1000 person years (95% confidence interval: 8.5-10.2). Most women received hormonal treatment (406/881; 46%) within three months of diagnosis, but many (387/881; 44%) received no medication. The LNG-IUS was prescribed for 2.4%, but there was no significant increase in the number of prescriptions over time. Conclusion: In this cohort, most women with HMB were treated with oral hormone therapy, and few received the LNG-IUS. If patients are to benefit from the LNG-IUS, further research is needed into the reasons for this lack of change in prescribing practices.

Real-life data on antibiotic prescription and sputum culture diagnostics in acute exacerbations of COPD in primary care.

BACKGROUND: Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) are generally treated with optimization of bronchodilation therapy and a course of oral corticosteroids, mostly without antibiotics. The Dutch guidelines recommend prudent use of antibiotics, with amoxicillin or doxycycline as first choice. Here we evaluate adherence to these guidelines with regard to antibiotic prescription in AECOPD in primary care and the use of sputum cultures. METHODS: We retrospectively analyzed a longitudinal cohort of patients in three primary care practices in the north-eastern region of the Netherlands from 2009 to 2013 (n=36,172 subjects) participating in the Registration Network Groningen. Antibiotics prescribed for AECOPD -10/+28 days from the start date of corticosteroid courses were evaluated. In addition, we assessed regional data on the susceptibility of respiratory pathogens from COPD patients. RESULTS: We identified 1,297 patients with COPD. Of these, 616 experienced one or more exacerbations, resulting in a total of 1,558 exacerbations, for which 1,594 antibiotic courses were prescribed. The recommended antibiotics doxycycline and amoxicillin accounted for 56% of the prescribed antibiotics overall and for 35% in subsequent antibiotic courses. The alternative choices were not based on culture results because only in 67 AECOPD events (2.9%) sputum samples were taken. Regional data including 3,638 sputum samples showed that pathogens relevant in AECOPD were detected in 19% of cultures. CONCLUSION: Our study shows that guidelines regarding the prescription of antibiotics are poorly followed, particularly in recurrent exacerbations. Sputum cultures were performed in a small minority of cases. Performing sputum diagnostics in patients with early treatment failure or a repeated exacerbation when antibiotic treatment is started may further rationalize antibiotic treatment.

Towards a differentiated capitation system: relation between patient characteristics, contacts and costs.

BACKGROUND AND OBJECTIVE: A new payment system could curb primary health care costs. A differentiated capitation system based on patient characteristics could be the best mix for payment. To test the feasibility of such a system, we examined the number of contacts between patients and general practitioners (GPs), the related costs and the relationship with age, sex and comorbidity. METHODS: A retrospective observational study included 29304 primary care patients in the Netherlands. Age, sex and comorbidity were related to number of contacts per patients per year and costs using a negative binomial regression analysis. RESULTS: Males, younger patients and patients with no comorbidities visit their GP least often. Medically unexplained physical symptoms, diabetes and severe back complaints generate the most contacts; diabetes is specifically related to higher costs. CONCLUSION: Several patient characteristics are related to the number of contacts patients have with their GP and the consecutive remuneration. This study can be used as an input to create a differentiated capitation system.

Radiating low back pain in general practice: incidence, prevalence, diagnosis, and long-term clinical course of illness.

OBJECTIVE: The aim of this study was to calculate the incidence and prevalence of radiating low back pain, to explore the long-term clinical course of radiating low back pain including the influence of radiculopathy (in a subsample of the study population) and non-radiating low back pain thereon, and to describe general practitioners' (GPs') treatment strategies for radiating low back pain. DESIGN: A historic prospective cohort study. SETTING: Dutch general practice. SUBJECTS: Patients over 18 years of age with a first episode of radiating low back pain, registered by the ICPC code L86. MAIN OUTCOME MEASURES: Incidence and prevalence, clinical course of illness, initial diagnoses established by the GPs, and treatment strategies. RESULTS: Mean incidence was 9.4 and mean prevalence was 17.2 per 1000 person years. In total, 390 patients had 1193 contacts with their GPs; 50% had only one contact with their GP. Consultation rates were higher in patients with a history of non-radiating low back pain and in patients with a diagnosis of radiculopathy in the first five years. In this study's subsample of 103 patients, L86 episodes represented radiculopathy in 50% of cases. Medication was prescribed to 64% of patients, mostly NSAIDs. Some 53% of patients were referred, mainly to physiotherapists and neurologists; 9% of patients underwent surgery. CONCLUSION: Watchful waiting seems to be sufficient general practice care in most cases of radiating low back pain. Further research should be focused on clarifying the relationship between radicular radiating low back pain, non-radicular radiating low back pain, and non-radiating low back pain.

Increased primary health care use in the first year after colorectal cancer diagnosis.

OBJECTIVE: The view that the general practitioner (GP) should be more involved during the curative treatment of cancer is gaining support. This study aimed to assess the current role of the GP during treatment of patients with colorectal cancer (CRC). DESIGN: Historical prospective study, using primary care data from two cohorts. SETTING: Registration Network Groningen (RNG) consisting of 18 GPs in three group practices with a dynamic population of about 30,000 patients. SUBJECTS: Patients who underwent curative treatment for CRC (n = 124) and matched primary care patients without CRC (reference population; n = 358). MAIN OUTCOME MEASURES: Primary healthcare use in the period 1998-2009. FINDINGS: Patients with CRC had higher primary healthcare use in the year after diagnosis compared with the reference population. After correction for age, gender, and consultation behaviour, CRC patients had 54% (range 23-92%) more face-to-face contacts, 68% (range 36-108%) more drug prescriptions, and 35% (range -4-90%) more referrals compared with reference patients. Patients consulted their GP more often for reasons related to anaemia, abdominal pain, constipation, skin problems, and urinary infections. GPs also prescribed more acid reflux drugs, laxatives, anti-anaemic preparations, analgesics, and psycholeptics for CRC patients. CONCLUSIONS: The GP plays a significant role in the year after CRC diagnosis. This role may be associated with treatment-related side effects and psychological problems. Formal guidelines on the involvement of the GP during CRC treatment might ensure more effective allocation and communication of care between primary and secondary healthcare services.

Skin lesions suspected of malignancy: an increasing burden on general practice.

BACKGROUND: Skin cancer is believed to impose a heavy burden on healthcare services, but the burden of skin lesions suspected of malignancy on primary healthcare has never been evaluated. Therefore the aim of this study was to determine the demand for care in general practice due to these suspected skin lesions (i.e. lesions that are suspected of malignancy by either the patient or the GP). METHODS: Registry study based on data (2001-2010) from the Registration Network Groningen. This is a general practice registration network in the northern part of the Netherlands with an average annual population of approximately 30,000 patients. All patient contacts are coded according to the International Classification of Primary Care (ICPC). Consultations for skin lesions suspected of malignancy were selected according to the assigned ICPC codes. Subsequently, the number of consultations per year and the annual percent change in number of contacts (using the JoinPoint regression program) were calculated and analysed. Additionally, the percentage of patients referred to secondary care or receiving minor surgery within one year after the first contact were calculated. RESULTS: From 2001 onwards we found an annual increase in demand for care due to skin lesions suspected of malignancy of 7.3% (p < 0.01) and in 2010 the benign:malignant ratio was 10:1. In total 13.0% of the patients were referred and after 2006, minor surgery was performed on 31.2% of the patients. Most surgeries and referrals took place within 30 days. CONCLUSIONS: Suspected skin lesions impose an increasing burden on primary healthcare and most likely on healthcare costs as well. General practitioners should therefore be trained in diagnosing skin lesions suspected of malignancy, as a high diagnostic accuracy can save lives in the case of melanoma, and may also prevent unnecessary, costly, excisions and referrals to secondary healthcare.

Survival of stroke patients after introduction of the 'Dutch Transmural Protocol TIA/CVA'.

BACKGROUND: Earlier research showed that healthcare in stroke could be better organized, aiming for improved survival and less comorbidity. Therefore, in 2004 the Dutch College of General Practitioners (NHG) and the Dutch Association of Neurology (NVN) introduced the 'Dutch Transmural Protocol TIA/CVA' (the LTA) to improve survival, minimize the risk of stroke recurrence, and increase quality of life after stroke. This study examines whether survival improved after implementation of the new protocol, and whether there was an increase in contacts with the general practitioner (GP)/nurse practitioner, registration of comorbidity and prescription of medication. METHODS: From the primary care database of the Registration Network Groningen (RNG) two cohorts were composed: one cohort compiled before and one after introduction of the LTA. Cohort 1 (n = 131, first stroke 2001-2002) was compared with cohort 2 (n = 132, first stroke 2005-2006) with regard to survival and the secondary outcomes. RESULTS: Comparison of the two cohorts showed no significant improvement in survival. In cohort 2, the number of contacts with the GP was significantly lower and with the nurse practitioner significantly higher, compared with cohort 1. All risk factors for stroke were more prevalent in cohort 2, but were only significant for hypercholesterolemia. In both cohorts more medication was prescribed after stroke, whereas ACE inhibitors were prescribed more frequently only in cohort 2. CONCLUSION: No major changes in survival and secondary outcomes were apparent after introduction of the LTA. Although, there was a small improvement in secondary prevention, this study shows that optimal treatment after introduction of the LTA has not yet been achieved.

Increased primary healthcare utilisation among women with a history of breast cancer.

PURPOSE: Little is known about the current role of the general practitioner (GP) in breast cancer follow-up care. This study explores primary healthcare use in the period after completion of primary breast cancer treatment. METHODS: A total of 336 women with a history of early-stage breast cancer treated with curative intent were identified in the primary care database of the Registration Network Groningen (RNG) (1998-2007) and matched with a reference population of 983 women without breast cancer on birth year and GP. RESULTS: Over the entire follow-up period (starting 1 year post-diagnosis), the median numbers of face-to-face contacts, drug prescriptions, and referrals in the patient group were significantly higher than those in the reference group: 4.0 vs. 3.2/year, 12.3 vs. 8.4/year, and 0.4 vs. 0.3/year, Mann-Whitney (M-W) test p < 0.001 for all differences. At least one annual face-to-face contact was observed for 96.7 % of patients and 92.9 % of women from the reference population (Chi-square test p = 0.011). More patients than women from the reference population had face-to-face contacts for reasons related to breast cancer or were prescribed hormone antagonists and aromatase inhibitors to treat breast cancer. The main predictor of higher rates of face-to-face contacts and drug prescriptions was a higher age at diagnosis. CONCLUSIONS: This study shows increased primary healthcare utilisation among women with a history of breast cancer, especially among the elderly. When follow-up is transferred to the primary care setting, new responsibilities of GPs might be incorporated into existing primary healthcare delivery.

Discontinuation of reimbursement of benzodiazepines in the Netherlands: does it make a difference?

BACKGROUND: In an attempt to control chronic benzodiazepine use and its costs in the Netherlands, health care insurance reimbursement of this medication was stopped on January 1st 2009. This study investigates whether benzodiazepine prescriptions issued by general practitioners changed during the first two years following implementation of this regulation. METHODS: Registry study based on data from all benzodiazepine users derived from the Registration Network Groningen. This general practice-based research network collects longitudinal data on the primary care administered to about 30,000 patients. Based on the number of quarterly accumulated prescription days, a comparison was made of benzodiazepine prescriptions issued between 2007/2008 and 2009/2010. Also investigated was which type of user (i.e. short-term or long-term) showed the most change. RESULTS: Information on benzodiazepine prescriptions among 5,200 patients from 16 consecutive trimesters between 2007 and 2010 was available for analysis. A significant reduction in prescription days was observed between 2007/2008 and 2009/2010. Overall, an estimated 1.73 (CI:-1.94 to -1.53; p<0.001) days were less prescribed per trimester after the termination of reimbursement. In particular, short-term users experienced a reduction in prescription days in 2009 and 2010. The number of long-term users decreased by 2.3%, while the number of individuals that did not use increased by 4.2%. CONCLUSIONS: A total reduction of almost 14 prescription days was observed over eight trimesters after implementation of the regulation to terminate the reimbursement of benzodiazepines. Short-term users were mainly responsible for this reduction in prescription days in 2009 and 2010. Although long-term users did not alter their benzodiazepine use in 2009 and 2010, the number of long-term users decreased slightly.

Prescribing of asthma medication in primary care for children aged under 10.

OBJECTIVE: To evaluate prescriptions of asthma medication for children in primary care. METHODS: Data on prescriptions of asthma medication for children aged 0-9 years were collected from a general practice-based network in the north eastern part of the Netherlands. Prevalence, incidence, indications, continuation beyond the age of 6 years, and predictors of continuation, were determined. RESULTS: Prevalence of prescriptions was about 80 per 1000 person years. An asthma diagnosis was registered in 40% of the children with a first prescription and in 70% of the children with six or more prescriptions. Discontinuation of asthma medication was between 60 and 90%. Continuation was more likely in children with a first prescription at age 2 or 3 as compared to children starting treatment at age < or =1 year. Children with prescriptions for beta2-agonists and inhaled corticosteroids were more likely to continue treatment than children with beta2-agonist monotherapy prescriptions. CONCLUSION: Continuation of asthma medication in children is low. Age at first prescription and the type of asthma medication are predictors of continuation of asthma medication from preschool into school-age.
