Are low and high utilization related to the way GPs manage their practices? An observational study.

BACKGROUND: General practice care plays a key role in keeping healthcare effective and cost-efficient. However, variation in the utilization rates of practices may reveal variation in practice performance. Our research goal is to investigate whether the socio-demographic profile of the patients' area of residence and practice organization characteristics influence the low or high utilization of general practice care. METHODS: Data on the utilization of general practice care were derived from the electronic health records of 232 general practices participating in the NIVEL Primary Care Database for the year 2013. Census data for the year 2013 were matched with the postal code of the patients. A small area estimation (SAE) technique was used to calculate the estimated utilization rate for general practice care per practice based on the socio-demographic profile of the patients' area of residence. Subsequently, the actual utilization rates were compared to the estimated rates per practice. Linear regression analysis was used to link the differences between the actual and estimated utilization rates to practice organization characteristics. RESULTS: The socio-demographic profile of the patients' area of residence accounted for 25.7% of the estimated utilization rates per practice. Practice organization characteristics accounted for 19.3% of the difference between the actual utilization rates and the estimated rates. Practices had higher utilization rates than estimated when a practice was a dual practice, when it employed female GPs, when it employed other healthcare providers and/or when it offered more services related to a disease management programme. CONCLUSION: We found that utilization rates of general practice care can be partially explained by the socio-demographic profile of the patients' area of residence, but also by practice organization characteristics. Insight into these factors provides both GPs and the other stakeholders involved in the organization of general practice care with information to help reflect on the utilization of care.

[Do mental health nurses take over care from general practitioners?] / Verlicht de POH-GGZ de werkdruk van de huisarts?

OBJECTIVE: The objective of this study was to examine mental health care provided by general practitioners and by mental health nurses working in general practices. DESIGN: Observational research. METHOD: We analysed how many consultations with patients with mental health problems were recorded in Dutch general practices in the period 2010-2014. General practices with and without a mental health nurse were compared, and we investigated which patients were mainly treated by mental health nurses. RESULTS: An increasing number of patients visited the GP for mental health problems in the period 2010-2014. GPs collaborating with a mental health nurse recorded a somewhat higher number of patients with mental health problems than GPs without a mental health nurse, but used as many consultations per patient. Mental health nurses mainly treat females, adult patients, and patients with common mental health problems. CONCLUSION: Mental health nurses do not take over care from GPs, but provide additional mental health care to patients with mental health problems. Collaborating with a mental health nurse might increase GPs' alertness to record mental health problems.

Collaboration of general practitioners and exercise providers in promotion of physical activity a written survey among general practitioners.

BACKGROUND: General practitioners have an ideal position to motivate inactive patients to increase their physical activity. Most patients are able to exercise in regular local facilities outside the health care setting. The purpose of this study was to get insight into general practitioners perceptions and current practices regarding referral of patients to local exercise facilities. Furthermore, collaboration with exercise providers in the community was investigated, and motivators and barriers for referral. METHODS: A written questionnaire sent to a representative random sample of 800 Dutch general practitioners. Descriptive statistics and Chi(2) tests were used. RESULTS: All responding general practitioners (340) recommend their patients to take more exercise when necessary and 87 % say to refer patients sometimes. Limited motivation of the patient (44 %) and reduced health status (34 %) are the most mentioned barriers for advising patients to increase physical activity. When referred, most patients are send to a physical therapist (69 %) but also local exercise facilities were mentioned (54 %). The most important barrier for referring patients to local exercise activities are patients limited financial possibilities (46 %). Restricted knowledge of local exercise- or sport facilities was an additional barrier (19 %). There is little structural collaboration between general practitioners and exercise providers, but when collaboration exists general practitioners refer more often. Positive experiences of patients (67 %), affordable offers (59 %) and information of local exercise facilities (46 %) are seen as important promoting factors for referral. Although 32 % of the general practitioners think that good collaboration would be stimulating, regular meetings with sports and exercise providers were considered the least important for increasing referral (3 %). CONCLUSIONS: Dutch physicians have a positive attitude towards stimulating physical activity but referral to local exercise facilities is low. Referral is partly hindered by restricted knowledge of local exercise facilities. Although general practitioners think that collaboration is important for physical activity promotion, it should not cost them much extra time. A coordinator with knowledge of the local situation can facilitate contacts between GP practices and sports providers.

Short- and long-term effects of real-time medication monitoring with short message service (SMS) reminders for missed doses on the refill adherence of people with Type 2 diabetes: evidence from a randomized controlled trial.

AIMS: To investigate short- and long-term effects of real-time monitoring medication use combined with short message service (SMS) reminders for missed doses on refill adherence to oral anti-diabetic medication. METHODS: A randomized controlled trial with two intervention groups and one control group involving 161 participants with Type 2 diabetes with suboptimal adherence. For 6 months, participants in the SMS group (n = 56) were monitored and received SMS reminders if they missed their medication. Participants in the non-SMS group (n = 48) were only monitored. The control group (n = 57) was not exposed to any intervention. Primary outcome measure was refill adherence to oral anti-diabetic medication. Multi-level regression analyses were performed to examine intervention effects on adherence between and within groups after 1 and 2 years of follow-up. RESULTS: At baseline, mean refill adherence was comparable between the groups. After 1 year, adherence in the SMS group was significantly higher than in the control group (79.5% vs. 64.5%; P < 0.001) and showed a significant improvement from baseline (+16.3%; P < 0.001). Mean adherence in the non-SMS group reached 73.1% (+7.3%; P < 0.05), but did not differ from the control group (P = 0.06). After 2 years, the improved adherence in the SMS group persisted and remained significantly higher than in the control group (80.4% vs. 68.4%; P < .01), contrary to the non-SMS group whose adherence approached baseline level again (65.5%). CONCLUSIONS: This study shows the long-term effectiveness of real-time medication monitoring combined with SMS reminders in improving refill adherence. This new reminder system can strengthen the self-management of people with diabetes.

Dietetic treatment lowers body mass index in overweight patients: an observational study in primary health care.

BACKGROUND: Greater insight into the effectiveness of usual dietetic care will contribute to the ongoing development of dietetic services. The present study examined the change in body mass index (BMI) in overweight patients after dietetic treatment in primary care, the sources of variability and factors associated with BMI change. METHODS: This population-based observational study was based on data from a Dutch registration network of dietitians in primary health care. Data were derived from electronic medical records concerning 3960 overweight adult patients (BMI ≥ 25 kg m⁻²) who received usual care from 32 registered dietitians between 2006 and 2012. Multilevel linear regression analyses were conducted. RESULTS: Patients' BMI significantly (P < 0.001) decreased by 0.94 kg m⁻² on average during treatment. An additional reduction of 0.8 kg m⁻² was observed in patients treated for longer than 6 months. BMI decreased by 0.06 kg m⁻² for each additional unit in initial BMI above 31.6. Most (97%) variability in BMI change was attributed to patients and 3% to dietitians. Part of the variance between patients (11%) and dietitians (30%) was explained by patient sociodemographic characteristics, nutrition-related health aspects, initial body weight and treatment duration. CONCLUSIONS: Dietetic treatment in primary care lowers BMI in overweight patients. Patients' change in BMI was rather similar between dietitians. Greater BMI reductions were observed in those with a high initial BMI and those treated for at least 6 months. Future research is necessary to study the long-term effects of weight loss after treatment by primary healthcare dietitians, especially because many patients drop out of treatment prematurely.

Lazy sunday afternoons: the negative impact of interruptions in patients' daily routine on adherence to oral antidiabetic medication. A multilevel analysis of electronic monitoring data.

PURPOSE: Considerable variability in adherence over time exists. The aim of this study was to investigate to what extent deviations from the prescribed regimen in type 2 diabetes patients can be explained by characteristics of the individual 'medication intake moments' and the patient. METHODS: Medication intake of 104 non-adherent type 2 diabetes patients from 37 community pharmacies was electronically monitored for 6 months. The primary outcome measures were: (1) whether or not the intake occurred and (2) whether or not the intake occurred within the agreed-upon time period (correct timing). Multilevel logistic regression analyses were performed to account for the nested structure of the data. RESULTS: Medication intakes in the evening and during weekends and holidays were more likely to be incorrectly timed and also more likely to be completely missed. Irrespective of timing, most intakes occurred in the mornings of Monday through Thursday (96 %), and least intakes occurred on Saturday evening (82 %). Correctly timed intakes most often occurred on Monday and Tuesday mornings (61 %) in contrast to Sunday evenings (33 %). A patient's medication regimen was significantly associated with adherence. CONCLUSION: Based on our results, among patients who already have difficulties in taking their oral antidiabetic medication, interruptions in the daily routine negatively influence the intake of their medication. Professionals need to be aware of this variation in adherence within patients. As regular medication intake is important to maintain glycaemic control, healthcare professionals and patients should work together to find strategies that prevent deviations from the prescribed regimen at these problematic dosing times.

Integrating care by implementation of bundled payments: results from a national survey on the experience of Dutch dietitians.

INTRODUCTION: In the Netherlands, bundled payments were introduced as part of a strategy to redesign chronic care delivery. Under this strategy new entities of health care providers in primary care are negotiating with health insurers about the price for a bundle of services for several chronic conditions. This study evaluates the level of involvement of primary health care dietitians in these entities and the experienced advantages and disadvantages. METHODS: In August 2011, a random sample of 800 Dutch dietitians were invited by email to complete an online questionnaire (net response rate 34%). RESULTS: Two-thirds participated in a diabetes disease management programme, mostly for diabetes care, financed by bundled payments (n=130). Positive experiences of working in these programmes were an increase in: multidisciplinary collaboration (68%), efficiency of health care (40%) and transparency of health care quality (25%). Negative aspects were an increase in administrative tasks (61%), absence of payment for patients with comorbidity (38%) and concerns about substitution of care (32%). DISCUSSION/CONCLUSION: Attention is needed for payment of patients with co- or multi-morbidity within the bundled fee. Substitution of dietary care by other disciplines needs to be further examined since it may negatively affect the quality of treatment. Task delegation and substitution of care may require other competencies from dietitians. Further development of coaching and negotiation skills may help dietitians prepare for the future.

SMS reminders improve adherence to oral medication in type 2 diabetes patients who are real time electronically monitored.

BACKGROUND: Poor adherence to oral antidiabetics has a negative influence on glycaemic control in type 2 diabetes patients. Real Time Medication Monitoring (RTMM) combines real time monitoring of patients' medication use with SMS reminders sent only if patients forget their medication, aiming to improve adherence. This study aimed to investigate the effect of these SMS reminders on adherence to oral antidiabetics in patients using RTMM and investigate patients' experiences with RTMM. METHODS: Data were collected in a RCT involving 104 type 2 diabetes patients with suboptimal adherence to oral antidiabetics. Fifty-six patients were randomised to receive SMS reminders if they forgot their medication, 48 patients received no reminders. Primary outcome measure was adherence to oral antidiabetics registered with RTMM, measured as: (1) days without dosing; (2) missed doses; (3) doses taken within predefined standardized time windows. Patients' experiences were assessed with written questionnaires. RESULTS: Over the six-month study period, patients receiving SMS reminders took significantly more doses within predefined time windows than patients receiving no reminders: 50% vs. 39% within a 1-h window (p=0.003) up to 81% vs. 70% within a 4-h window (p=0.007). Reminded patients tended to miss doses less frequently than patients not reminded (15% vs. 19%, p=0.065). Days without dosing were not significantly different between the groups. The majority of patients reported positive experiences with RTMM and SMS reminders. CONCLUSION: RTMM with SMS reminders improves adherence of type 2 diabetes patients, especially the precision with which patients follow their prescribed regimen, and is well accepted by patients.

Long-term effectiveness of exercise therapy in patients with osteoarthritis of the hip or knee: a randomized controlled trial comparing two different physical therapy interventions.

OBJECTIVE: To determine if behavioral graded activity (BGA) results in better long-term effectiveness (5 years after inclusion) than usual exercise therapy (UC; usual care) in patients with osteoarthritis (OA) of the hip or knee. METHOD: Long-term follow-up study of a single blind cluster randomized trial comparing BGA and UC. One hundred and forty-nine patients out of the 200 included were followed until 60 months' follow-up. Primary outcome measures were pain, physical function, and patient global assessment. Furthermore, patient-oriented physical function, physical performance, health care utilization and the number of joint replacement surgeries were assessed. Assessments took place at 3, 9, 15 and 60 months' follow-up. Data were analyzed according to intent-to-treat principle. RESULTS: Both treatments showed beneficial within-groups effects in the long-term. In patients with knee OA no differences between treatments were found on the short-, mid-long and long-term. In patients with hip OA significant differences in favor of BGA were found at 3 months' (pain and physical performance) and 9 months' follow-up (pain, physical function, patients global assessment and patient-oriented physical function). Furthermore, UC resulted in patients with hip OA in more joint replacement surgeries compared to BGA (hazard ratio [HR], 2.87; 95% confidence interval [CI], 1.1; 7.3). CONCLUSION: No differences between treatment groups were found in the long-term on the primary outcome measures. Although more research is needed to confirm the study findings, the results indicate that BGA reduces the risk for joint replacement surgeries compared to UC in patients with hip OA, which probably can be explained by better outcome in favor of BGA in the short- and mid-long-term.

Estimating morbidity rates from electronic medical records in general practice. Evaluation of a grouping system.

OBJECTIVES: In this study, we evaluated the internal validity of EPICON, an application for grouping ICPC-coded diagnoses from electronic medical records into episodes of care. These episodes are used to estimate morbidity rates in general practice. METHODS: Morbidity rates based on EPICON were compared to a gold standard; i.e. the rates from the second Dutch National Survey of General Practice. We calculated the deviation from the gold standard for 677 prevalence and 681 incidence rates, based on the full dataset. Additionally, we examined the effect of case-based reasoning within EPICON using a comparison to a simple, not case-based method (EPI-0). Finally, we used a split sample procedure to evaluate the performance of EPICON. RESULTS: Morbidity rates that are based on EPICON deviate only slightly from the gold standard and show no systematic bias. The effect of case-based reasoning within EPICON is evident. The addition of case-based reasoning to the grouping system reduced both systematic and random error. Although the morbidity rates that are based on the split sample procedure show no systematic bias, they do deviate more from the gold standard than morbidity rates for the full dataset. CONCLUSIONS: Results from this study indicate that the internal validity of EPICON is adequate. Assuming that the standard is gold, EPICON provides valid outcomes for this study population. EPICON seems useful for registries in general practice for the purpose of estimating morbidity rates.

Loss to follow-up of cervical smears without endocervical columnar cells is not disturbing.

OBJECTIVE: To investigate the six-month recommended follow-up after mass screening of Pap smears because of the absence of endocervical columnar cells (ECC-) or ECC+ smears with atypical squamous or glandular cells of undetermined origin (ASCUS/AGUS) or low-grade squamous or glandular intraepithelial lesions (LSIL/LGIL) in a Dutch mass screening cervical cancer programme. METHODS: Data were extracted from computerised medical records of national representative Dutch general practices. We have studied the attendance at and the outcome of the subsequent Pap smears after a 6-month recommendation. RESULTS: The six-month follow-up was linked to 8.7% of the Pap smears (n = 1,002); 77.6% were without endocervical columnar cells (ECC-). Clear differences were found between the follow-up of ECC+ and ECC- smears; after 36 weeks of follow-up of 43.5% the women had an ECC- smear and 66.9% had other conditions. For initial ECC- Pap smears, 84.1% had no abnormalities in the subsequent Pap smear; for initial ECC+ Pap smears, in about 64% of the cases no abnormalities were found (p < 0.0001). CONCLUSIONS: Repeating ECC- smears has a low follow-up rate but also lacks evidence-based necessity. However, for the other 6-month recommended Pap smears, one in five women had still not responded within one year, so improvement is necessary.

Monitoring health inequalities through general practice: the Second Dutch National Survey of General Practice.

BACKGROUND: For the second time a plan to monitor public health and health inequalities in the Netherlands through general practice was put into action: the Second National Survey of General Practice (DNSGP-2, 2001). The first aim of this paper is to describe the general design of DNSGP-2. Secondly, to describe self assessed health inequalities in the Netherlands. Thirdly, to present differences in prevalence of chronic conditions by educational attainment using both self-assessed health and medical records of GPs. Finally, inequalities in 1987 (DNSGP-1) and 2001 will be compared. METHODS: Data were collected from 96 (1987) and 104 (2001) general practices. The data include background information on patients collected via a census, approximately 12,000 health interview surveys per time point and more than one million recorded contacts of patients with their GPs in both years. The method of statistical analysis is logistic regression. RESULTS: The analyses shows that the lower educated have significantly higher odds of feeling unhealthy and having chronic conditions in 2001. Diabetes and myocardial infarction (GP data) showed the largest difference in prevalence between educational groups (OR 2.5 and 2.4, self-reported data). The way the data is collected (self-assessment versus GP registration) hardly affects the magnitude of the educational differences in the prevalence of chronic conditions. The pattern of health inequalities across chronic conditions in 1987 and 2001 hardly differs. Diabetes doubled in prevalence and health inequalities were not significant in 1987, but compared to the other conditions were largest in 2001 (OR 1.1 versus 2.5). CONCLUSION: Health inequalities were shown to be substantial in 2001 and persistent over time. Socio-economic differences were shown to be similar using self-assessed health data and GP data. Hence, a person's educational attainment did not appear to play a part in presenting health problems to the GP.

Shared help seeking behaviour within families: a retrospective cohort study.

OBJECTIVE: To examine the extent to which the family influences individual use of general practitioner care. DESIGN: Retrospective cohort study of all consultations in one calendar year. Multilevel modelling was used to analyse contact frequencies of individuals within families within practices. SETTING: General practice in the Netherlands. PARTICIPANTS: 42 262 families with children aged 2-21 years registered in 96 practices. MAIN OUTCOME MEASURES: Family influence on individual frequency of contact with general practice and correlation in frequency of contacts between parents and children. RESULTS: After correction for patients' age and sex, analysis of siblings indicates that 22% of the variance in frequencies of contact can be ascribed to influence of the family. This means that contact frequencies of family members within families resemble each other, whereas differences in contact frequencies exist between families. Almost 6% of the variance refers to differences between practices and 73% of the variance refers to individual differences. The strongest correlations were found between mothers and children and between children. CONCLUSIONS: The extent of shared help seeking behaviour within families has considerable implications in the context of the practice.

Vaccination of high-risk patients against influenza: impact on primary care contact rates during epidemics. Analysis of routinely collected data.

A general practice (GP) based retrospective cohort study was conducted to assess the effects of influenza vaccination on the primary care contact rate during influenza epidemics. Given the rising workload of family physicians, particularly due to ageing of the population, it is very relevant to know to whether influenza vaccination of high-risk patients reduces the contact rate during epidemics. No effect of vaccination was found on the contact rate of GP during a mild epidemic period. During a 'normal' influenza epidemic, the workload was reduced through fewer contacts by patients with cardiovascular or diabetic diseases. Epidemic periods severe enough to show contact rate reduction occurred approximately every other year.

The effectiveness of quality systems in nursing homes: a review.

BACKGROUND: The need for quality improvement and increasing concern about the costs and appropriateness of health care has led to the implementation of quality systems in healthcare organisations. In addition, nursing homes have made significant investments in their development. The effects of the implementation of quality systems on health related outcomes are not yet clear. OBJECTIVE: To examine evidence in the literature on whether quality systems have an impact on the care process and the satisfaction and health outcomes of long term care residents. METHODS: Review of the literature. RESULTS: The 21 empirical studies identified concerned quality system activities such as the implementation of guidelines; providing feedback on outcomes; assessment of the needs of residents by means of care planning, internal audits and tuition; and an ombudsman for residents. Only four articles described controlled studies. The selected articles were grouped according to five focal areas of quality. The opinion of residents was seldom used to evaluate the effectiveness of quality systems. The effects on care processes and the health outcomes of long term care residents were inconsistent, but there was some evidence from the controlled studies that specific training and guidelines can influence the outcomes at the patient level. CONCLUSIONS: The design of most of the studies meant that it was not possible to attribute the results entirely to the newly implemented quality system. As it is difficult in practice to design a randomised controlled study, future research into the effectiveness of quality systems should not only focus on selected correlates of quality, but should also include a qualitative and quantitative (multivariate and multilevel) approach. The methods used to measure quality need to be improved.

GP income in relation to workload in deprived urban areas in The Netherlands. Before and after the 1996 pay review.

BACKGROUND: General practitioner workload is higher in deprived urban areas and for the elderly. This led to the introduction of additional GP payments regarding these patients, in the UK and in the Netherlands. This study examines whether this has resulted in more equal payment for work done in the Netherlands. METHODS: GP workload and income have been assessed on the basis of a survey among 1154 GPs (response: 62%). RESULTS: Suggest that total GP income is still lower in deprived areas, but per hour and per patient contact the additional payments gave equity. CONCLUSION: It is thus concluded that Dutch deprivation payments effectively compensate GPs in deprived areas for their higher workload.

The impact of legislative versus non-legislative quality policy in health care: a comparison between two countries.

UNLABELLED: An important aim of the government's quality policy is to stimulate quality management (QM) in health care organizations. The relationship between the government's quality policy and QM in health care organizations is unknown. This article explores that relationship by comparing two countries with different quality policies, The Netherlands and Finland. In The Netherlands QM is required by law and health care is organized at national level. In Finland, QM is not required by law and the responsibilities for organizing health care are delegated to the municipalities. The question is whether or not these differences in national policy are reflected in the extent and effectiveness of QM in health care organizations in the two countries. A cross sectional survey was conducted in late 1999. Data about QM in both countries were gathered by questionnaire. The subsectors involved were hospitals, care for the disabled and care for the elderly. A total of 1172 health care organizations participated in the study (response rate 64%). The results show that-in keeping with our hypothesis-slightly more QM-activities and more patient participation were found in Dutch health care organizations compared with the Finnish ones. However, contrary to our expectations, the Finnish organizations reported more perceived effects of their QM-activities. Further analyses showed that some QM-activities are more closely related to the effectiveness of QM than others. In particular, cyclic quality improvement procedures, human resource management and the flexible attitude of employees showed the strongest relationship with the perceived effects of QM. The difference between the national approach in The Netherlands and the decentralized approach in Finland did not, as we had assumed, result in more regional variation in QM in Finland. CONCLUSIONS: a government's quality policy may have some influence on the extent of QM in health care organizations. However, more QM-activities do not necessarily imply more effects. RECOMMENDATIONS: since QM-activities differ in the degree to which they bring about changes and improvements in care, it is recommended that policy makers promote those QM-activities, which are the most potent, in order to improve the quality of care.

Environmental and organizational determinants of quality management.

The aim of the study was to obtain more insight into the organizational and environmental determinants of the implementation of quality management in health care organizations. Primary survey data were collected in 1995 in a large nationwide study within 15 fields of health care and health care-related social services in The Netherlands. In general, there are more differences between health care organizations than between fields of health care. Environmental influence was found to be less important than was expected. Care-oriented organizations have a greater opportunity to involve their patients. It seems that apart from patients, the perceived pressure from other third parties has little influence on the implementation of quality management in health care organizations.

The impact of area deprivation on differences in health: does the choice of the geographical classification matter?

OBJECTIVE: Many studies show the average health status in deprived areas to be poorer and the use of health care to be higher, but there is hardly any information on the impact of the geographical classification on the size of these differences. This study examines the impact of the geographical classification on the clustering of poor health per area and on the size of the differences in health by area deprivation. DESIGN: Data on self reported health regarding 5121 people were analysed using three classifications: neighbourhoods, postcode sectors and boroughs. Multilevel logistic models were used to determine the clustering of poor health per area and the size of the differences in health by area deprivation, without and subsequently with adjustment for individual socioeconomic status. SETTING: General population aged 16 years and over of Amsterdam, The Netherlands. MAIN OUTCOME MEASURES: Self rated health, mental symptoms (General Health Questionnaire, 12-item version), physical symptoms and long term functional limitations. MAIN RESULTS: The clustering of poor health is largest in neighbourhoods and smallest in postcode sectors. Health differences by area deprivation differ only slightly for the three geographical classifications, both with and without adjustment for individual socioeconomic status. CONCLUSIONS: In this study, the choice of the geographical classification affects the degree of clustering of poor health by area but it has hardly any impact on the size of health differences by area deprivation.
