Factors affecting the manual linking of clinical progress notes to problems in daily clinical practice: A retrospective quantitative analysis and cross sectional survey.

This cross sectional study examines how patient characteristics, doctor characteristics, and doctors' education and attitudes affect the extent to which doctors link progress notes to clinical problems. The independent effects of patient characteristics on the linking of notes was examined with a mixed model logistic regression. The effects of doctor characteristics and doctors' education and attitudes on the link ratio was analyzed with univariate analysis of variance. A survey was used to obtain arguments and attitudes on linking notes. For "patient characteristics", the odds of linking increased with an increase in the number of problems or hospital days, decreased, with an increase in the number of involved doctors, medical specialties or the number of notes. For "doctor characteristics", the link ratio increased with more work experience. For "doctors' education and attitudes", the link ratio increased with more familiarity in linking notes and belief in the added value of problem oriented charting. "Overview" was the most cited reason for linking; "I don't know how" the most cited reason for not linking. There is a huge variation within and between all disciplines. Important arguments, for and against, are found. Recommendations for policymakers and medical leadership are given to maximize the benefits.

Very frequent physical aggression and vocalizations in nursing home residents with dementia.

OBJECTIVES: We investigated the 2-week prevalence and correlates of very frequent physical aggression (PA) and vocalizations in nursing home (NH)-residents with dementia. METHOD/DESIGN: This cross-sectional study used combined data of 2074 NH-residents from four studies, collected from 119 dementia special care units in 26 Dutch NH. Very frequent PA was defined as scoring 6 or 7 on the items 'hitting', pushing', 'biting' and 'kicking' of the Cohen Mansfield Agitation Inventory; very frequent vocalizations as scoring 6 or 7 on 'screaming' and 'making strange noises'. We compared NH-residents with very frequent PA or vocalizations with residents with less frequent PA or vocalizations, assessing correlates using univariate and multivariate multilevel logistic regression analyses. RESULTS: We found a 2-week prevalence of 2.2% (95% confidence interval (CI): 1.63-2.89) of very frequent PA and 11.5% of very frequent vocalizations (95% CI: 10.23-12.98). Very frequent PA was only associated with apathy (odds ratio (OR)=1.93, 95% CI: 1.04-3.61). Correlates of very frequent vocalizations were age (OR = 0.97, 95% CI: 0.951-0.998), dementia severity (overall p-value 0.020), antipsychotic drug use (OR = 1.56, 95% CI: 1.08-2.26), antiepileptic drug use (OR = 2.75, 95% CI: 1.34-5.68) and euphoria (OR = 2.01, 95% CI: 1.22-3.31). CONCLUSION: Characteristics of NH-residents with very frequent PA or very frequent vocalizations differ from those of NH-residents with less frequent PA or vocalizations. Frontal lobe damage, boredom, pain and/or external factors may explain several of the found associations, but further research is necessary. Our findings may contribute to better care for these residents and thereby to improving their quality of life.

The course of neuropsychiatric symptoms in patients with dementia in primary care.

BACKGROUND: During the course of dementia, most people develop some type of neuropsychiatric symptoms (NPS), which result in lower quality of life, high caregiver burden, psychotropic drug use and a major risk of institutionalization. Studies on NPS in people with dementia have been mainly conducted in clinical centres or psychiatric services. OBJECTIVES: To investigate the course of NPS in people with dementia in primary care. METHODS: Analysis of (cumulative) prevalence and incidence, persistence and resolution based on data collected during an assessment at home of a prospective naturalistic cohort study in primary care in a sample of 117 people with dementia and their informal caregivers. Subsyndromes of NPS were assessed with the Neuropsychiatric Inventory (NPI) and Cohen-Mansfield Agitation Inventory. Multivariate analyses were used to detect determinants for the course of NPS. RESULTS: The mean age of the people with dementia was 78.6 years, and 52% were female. Mean Mini-Mental State Examination total score was 19.5, mean NPI total score 15.7. The most prevalent clinically relevant subsyndromes of the NPI were hyperactivity and mood/apathy, and the most prevalent individual NPS were aberrant motor behaviour (28%), agitation/aggression (24%) and apathy/indifference (22%). Of the people with dementia, 72.3% had one or more symptoms of the mood/apathy and 75.3% of the hyperactivity subsyndrome. CONCLUSIONS: GPs should be aware of NPS in people with dementia and should actively identify them when they visit these patients or when informal caregivers consult them. Timely diagnosing facilitates adequate professional care.

Training GPs to improve their management of work-related problems: results of a cluster randomized controlled trial.

BACKGROUND: Paying attention to their patients' work and recognizing work-related problems is challenging for many general practitioners (GPs). OBJECTIVES: To assess the effect of training designed to improve the care for patients with work-related problems in general practice. METHODS: A cluster randomized controlled trial among 32 Dutch GPs. GPs in the intervention group received five-hour training. GPs in the control group were not trained. Included patients (age 18-63, working ≥12 h per week) completed baseline questionnaires and follow-up questionnaires planned after one year. Primary outcome at patient level was patients' expectations about their ability to work, measured using the return-to-work self-efficacy scale (RTW-SE). Primary outcomes on GP level were their use of ICPC-code Z05 ('work-related problem') per 1000 working-age patients and percentage of the electronic medical files of working-age patients in which information about occupation had been recorded. RESULTS: A total of 640 patients completed the baseline questionnaire and 281 the follow-up questionnaire. We found no statistically significant differences in patients' RTW-SE scores: intervention 4.6 (95%CI: 4.2-5.0); control 4.5 (95%CI: 4.1-4.9). Twenty-nine GPs provided data about the GP-level outcomes, which showed no statistically significant differences: use of ICPC code Z05 11.6 (95%CI: 4.7-18.6) versus 6.0 (95%CI: -1.2 to 13.2) per 1000 working-age patients; recording of occupation 28.8% (95%CI: 25.8-31.7) versus 28.6% (95%CI: 25.6-31.6). CONCLUSION: Training GPs did not improve patients' work-related self-efficacy or GPs' registration of work-related problems and occupation.

The Progression of Dementia and Cognitive Decline in a Dutch 2-Year Cohort Study of People with Young-Onset Dementia.

BACKGROUND: The progression of dementia in people with young-onset dementia (YOD) is relatively unknown. OBJECTIVE: To investigate the progression of dementia and cognitive decline in the three most common subtypes in YOD and to explore which factors are associated with this course. METHODS: The course of dementia was examined in 198 people with YOD. The primary outcomes were cognitive function, as assessed by the Mini-Mental State Examination (MMSE) and dementia severity, as assessed by the Global Deterioration Scale (GDS). Mixed-model analyses were used to explore factors associated with the course of dementia of the diagnostic sub-types. RESULTS: The mean overall two-year progression of dementia severity was 0.9 GDS points, this was a statistically significant change (p = 0.012) and was not significant different for the three dementia subtypes. The mean overall two-year decline in cognitive function was 1.6 points on the MMSE. The differences in cognitive decline were statistically significant (p = 0.046) among the three diagnosis groups, AD participants showed the greatest decline, of 2.3 points. In addition to lower education (p = 0.010), higher scores on the Neuropsychiatric Inventory (NPI) sub-syndromes psychosis (p < 0.001) and hyperactivity (p = 0.002) were associated with higher rates of cognitive decline. In contrast, higher scores on the NPI affect cluster were associated with lower levels of cognitive decline (p < 0.001). CONCLUSION: Different YOD subtypes show different rates of decline in cognitive functioning, and this decline seems less progressive compared to those observed in studies in late-onset AD. Further research is needed to evaluate whether managing neuropsychiatric symptoms can positively influence the decline of cognitive function.

Change in frequency of patient requests for diagnostic screening and interventions during primary care encounters from 1985 to 2014.

Background: The reason why patients contact a care provider, the reason for encounter (RFE), reflects patients' personal needs and expectations regarding medical care. RFEs can be symptoms or complaints, but can also be requests for diagnostic or therapeutic interventions. Objectives: Over the past 30 years, we aim to analyse the frequency with which patients consult a GP to request an intervention, and to analyse the impact of these requests on the subsequent diagnostic process. Methods: We included all patients with a request for diagnostics, medication prescription or referral from 1985 to 2014. We analysed the number of requests, granted requests and interventions originating from a request. We compared the final diagnosis (symptom or disease diagnosis) between patients with and without a request. Design and Setting: This is a retrospective cohort study with data from Family Medicine Network, a Dutch primary healthcare registration network. Results: Over time, patients more often present to their GP with a request for intervention. GPs are increasingly compliant with these requests. Patients presenting with a request for intervention are more likely to be diagnosed with a symptom rather than a disease. Conclusion: This study provides insight into the changes in patients' and GPs' behaviour and patients' influence on the medical process, and confirms the clinical relevance of the RFE. This study could support GPs in daily practice when deciding whether or not to grant a request.

Two-Year Course of Quality of Life in Nursing Home Residents with Dementia.

OBJECTIVE: To assess the course of quality of life (QoL) in nursing home residents with dementia and to study its predictors. METHODS: This longitudinal, multicenter, observational cohort study with a 2-year follow-up looked at 290 residents with dementia, who lived in 14 dementia special care units in nine nursing homes in the Netherlands. QoL was assessed with the Qualidem, providing a total score and QoL profile with nine subscales. Residents were assessed at five assessments: every 6 months during 2 years. A linear mixed model was used for data analysis. RESULTS: No change was found in the Qualidem total score (range: 0-111) over 2 years. However, a significant increase of QoL over time was seen in the subscales "Care relationship," "Negative affect," "Restless tense behavior," "Positive self-image," "Social isolation," and "Feeling at home." A significant decrease of QoL was seen in the subscales "Positive affect," "Social relations," and "Having something to do." Most predictors of the course of Qol were found for the subscales "Positive self-image" (sex, Global Deterioration Scale, Severe Impairment Battery, Activities of Daily Living, and Neuropsychiatric Inventory) and "Having something to do" (Global Deterioration Scale, Severe Impairment Battery, and Activities of Daily Living). Sex and Neuropsychiatric Inventory at baseline were the predictors found most frequently. CONCLUSION: The total QoL score was stable over a 2-year period. However, QoL subscales showed multidirectional changes. The largest QoL decline in the subscale "Having something to do" suggests that more attention should be given to useful activities in nursing home care.

Prevalence of primary aldosteronism in primary care: a cross-sectional study.

BACKGROUND: Primary aldosteronism (PA) is the most frequent cause of secondary hypertension. Reported prevalences of PA vary considerably because of a large heterogeneity in study methodology. AIM: To examine the proportion of patients with PA among patients with newly diagnosed, never treated hypertension. DESIGN AND SETTING: A cross-sectional study set in primary care. METHOD: GPs measured aldosterone and renin in adult patients with newly diagnosed, never treated hypertension. Patients with elevated aldosterone-to-renin ratio and increased plasma aldosterone concentration underwent a saline infusion test to confirm or exclude PA. The source population was meticulously assessed to detect possible selection bias. RESULTS: Of 3748 patients with newly diagnosed hypertension, 343 patients were screened for PA. In nine out of 74 patients with an elevated aldosterone-to-renin ratio and increased plasma aldosterone concentration the diagnosis of PA was confirmed by a saline infusion test, resulting in a prevalence of 2.6% (95% confidence interval = 1.4 to 4.9). All patients with PA were normokalaemic and 8 out of 9 patients had sustained blood pressure >150/100 mmHg. Screened patients were younger (P<0.001) or showed higher blood pressure (P<0.001) than non-screened patients. CONCLUSION: In this study a prevalence of PA of 2.6% in a primary care setting was established, which is lower than estimates reported from other primary care studies so far. This study supports the screening strategy as recommended by the Endocrine Society Clinical Practice Guideline. The low proportion of screened patients (9.2%), of the large cohort of eligible patients, reflects the difficulty of conducting prevalence studies in primary care clinical practice.

Nursing Home Residents with Dementia and Very Frequent Agitation: A Particular Group.

OBJECTIVE: Although many nursing home residents with dementia show agitation, hardly any literature is published about very frequent agitation. The WAALBED-III study focuses on the 2-week prevalence and correlates of very frequent agitation in these residents. DESIGN: Cross-sectional study using combined data of four studies. SETTING: One hundred nineteen dementia special care units in twenty-six nursing homes in The Netherlands. PARTICIPANTS: Two thousand seventy-four residents with dementia. MEASUREMENTS: We operationally defined very frequent agitation as having a score of 6 (several times a day) or 7 (several times an hour) on at least five items of the Cohen Mansfield Agitation Inventory (CMAI) combined with a CMAI total score above the 90th percentile. To assess the association of demographic and behavioral characteristics with very frequent agitation, we performed a multivariate multilevel logistic regression analysis. RESULTS: The 2-week prevalence of very frequent agitation was 7.4% (95% CI: 6.374-8.634). Correlates for very frequent agitation were age (OR: 0.967, 95% CI: 0.942-0.992), dementia severity (GDS 6 = OR: 3.636, 95% CI: 1.929-6.875; GDS 7 = OR: 2.951, 95% CI: 1.321-6.588), delusions (OR: 2.480, 95% CI: 1.555-3.956), anxiety (OR: 1.904, 95% CI: 1.259-2.881), euphoria (OR: 3.712, 95% CI: 2.171-6.337) and irritability (OR: 4.411, 95% CI: 2.854-6.816). CONCLUSIONS: To our knowledge, this study is the first to report prevalence data and correlates about nursing home residents with very frequent agitation. We found several correlated factors for very frequent agitation. Still, further research is needed for a better understanding of the behavior of this group, and to identify good treatment options.

Is uncertain vulvovaginal candidiasis a marker of vulvodynia? A study in a Dutch general practice research database.

BACKGROUND: A recent Dutch study in general practice showed a clear relationship between the diagnosis of vulvovaginal candidiasis (VVC) and symptoms suggestive of provoked vulvodynia (PVD). PVD accounts for the largest group of vulvar pains, but is often not recognised by GPs. AIM: To investigate whether diagnostic uncertainty about VVC in general practice could also point to the diagnosis of PVD, and whether and how this diagnostic uncertainty affects management. DESIGN & SETTING: An observational study in 2014 in Dutch general practices of the NIVEL Primary Care Database. METHOD: Women with an uncertain diagnosis of VVC were distinguished from those with certain VVC based on the occurrence of recurrent episodes and persisting complaints, despite treatment. Factors known to be associated with PVD were hypothesised to be more prevalent in women with uncertain VVC. Data on symptom management by GPs were collected. RESULTS: In total 7066 women with VVC or uncertain VVC were included. Uncertain VVC was found to account for 28% of these patients. Compared to VVC, the group uncertain VVC included significantly more women with female genital symptoms, tiredness, irritable bowel syndrome (all P<0.001), feeling anxious, reduced sexual desire, depressive disorder, relationship problems, and micturition symptoms (all P<0.05). Compared to VVC, the group uncertain VVC included significantly higher mean numbers of telephone consultations (P<0.001), more referrals to gynaecology (P = 0.009), and higher mean numbers of prescriptions per patient (P<0.001). CONCLUSION: This study's findings indicate that uncertain VVC could be a marker of PVD. GPs might reconsider their diagnostics and management when women present recurrent and persistent vulvovaginal complaints, especially if accompanied by dyspareunia, functional syndromes, micturition symptoms, and psychological conditions.

Frailty is associated with delirium and mortality after transcatheter aortic valve implantation.

OBJECTIVE: We hypothesised that frailty assessment is of additional value to predict delirium and mortality after transcatheter aortic valve implantation (TAVI). METHODS: Observational study in 89 consecutive patients who underwent TAVI. Inclusion from November 2012 to February 2014, follow-up until April 2014. Measurement of the association of variables from frailty assessment and cardiological assessment with delirium and mortality after TAVI, respectively. RESULTS: Incidence of delirium after TAVI: 25/89 (28%). Variables from frailty assessment protectively associated with delirium were: Mini Mental State Examination, (OR 0.79; 95% CI 0.65 to 0.96; p=0.02), Instrumental Activities of Daily Living (OR 0.79; 95% CI 0.63 to 0.99; p=0.04) and gait speed (OR 0.05; 95% CI 0.01 to 0.50; p=0.01). Timed Up and Go was predictively associated with delirium (OR 1.14; 95% CI 1.03 to 1.26; p=0.01). From cardiological assessment, pulmonary hypertension was protectively associated with delirium (OR 0.34; 95% CI 0.12 to 0.98; p=0.05). Multivariate logistic analysis: Nagelkerke R2=0.359, Mini Mental State Examination was independently associated with delirium. Incidence of mortality: 11/89 (12%). Variables predictively associated with mortality were: the summary score Frailty Index (HR 1.66, 95% CI 1.06 to 2.60; p=0.03), European System for Cardiac Operative Risk Evaluation (EuroSCORE) II (HR 1.14, 95% CI 1.06 to 1.22; p<0.001) and complications (HR 4.81, 95% CI 1.03 to 22.38; p=0.05). Multivariate Cox proportional hazards analysis: Nagelkerke R2=0.271, Frailty Index and EuroSCORE II were independently associated with mortality. CONCLUSIONS: Delirium frequently occurs after TAVI. Variables from frailty assessment are associated with delirium and mortality, independent of cardiological assessment. Thus, frailty assessment may have additional value in the prediction of delirium and mortality after TAVI.

Gender differences in clusters of NPS in Dutch nursing homes - a factor analysis.

BACKGROUND: Neuropsychiatric symptoms (NPS) have a high prevalence among patients with dementia, up to 80%. NPS can be grouped by type and stage of dementia. However, NPS have not previously been grouped by gender. Our objective was to investigate whether NPS cluster differently in men or women in the nursing home patients. METHODS: Factor analysis to assess the clustering of items in the Cohen-Mansfield Agitation Inventory (CMAI) and Neuropsychiatric Inventory-Nursing home version (NPI-NH) into components, for both scales and for gender. Differences in symptom clustering between male and female patients were assessed using a three-step procedure: (1) identifying a gender specific distinctive item, (2) describe the correlation between the distinctive item with any other item in this cluster, (3) testing whether the correlation between a distinctive item and any other item in the cluster (which is present in both sexes) is different for males and females using a general linear model. RESULTS: Our database consisted of 1,609 patients. There were five male and three female clusters for NPI-NH and eight male and seven female clusters for CMAI. There were three distinctive items in the NPI-NH and ten in the CMAI. CONCLUSIONS: There are other clusters of NPS in males and females. Our analysis revealed more significant relations in female than male patients. This might have an implication on the clinical course.

Brief multimodal psychosomatic therapy in patients with medically unexplained symptoms: feasibility and treatment effects.

BACKGROUND: Patients repeatedly presenting with medically unexplained symptoms (MUS) to their GPs, suffer from their symptoms. Experts in the field suggest a multicomponent approach for these patients. Brief multimodal psychosomatic therapy (BMPT) is such an intervention. OBJECTIVES: To test the systematic identification of eligible patients, acceptability of BMPT and potential treatment effects of BMPT. METHODS: The participants in this randomized pilot trial, patients consulting their GPs more than once with MUS, were randomized to intervention [usual care (UC) and additional BMPT] or control condition (UC alone).We monitored the number of patients identified and recruited, trial recruitment and retention. Potential treatment effects were measured with perceived symptom severity [Visual Analogue Scale (VAS)]; patients' self-rated symptoms of distress, depression, anxiety and somatization [Four-Dimensional Symptom Questionnaire (4DSQ)]; symptoms of hyperventilation [Nijmegen Hyperventilation List (NHL)]; physical and mental health status and quality of life [Short-Form Health Survey-36 items (SF-36)]; and level of functioning (measure of general functioning). Follow-up was 1 year. RESULTS: A total of 42 patients could be included in the trial. Four patients withdrew after randomization and two patients were lost to follow-up, resulting in 36 patients (86%). During the 12-month follow-up after BMPT, there was an improvement in perceived symptom severity [adjusted mean difference -2.0, 95% confidence interval (CI) -3.6 to -0.3], in somatization (adjusted mean difference -4.4, 95% CI -7.5 to -1.4) and in symptoms of hyperventilation (adjusted mean difference -5.7, 95% CI -10.5 to -0.8). CONCLUSIONS: This randomized pilot study shows that a larger trial studying the effectiveness of BMPT in patients with MUS in primary care is feasible and useful.

Psychological distress in informal caregivers of patients with dementia in primary care: course and determinants.

BACKGROUND: The course of psychological distress in informal caregivers of patients with dementia has been investigated in longitudinal studies with conflicting outcomes. OBJECTIVES: We investigated the course and determinants of psychological distress in informal caregivers of patients with dementia in primary care. METHODS: In this prospective observational cohort study, data were collected at baseline, after 9 and 18 months. We assessed cognition and neuropsychiatric symptoms (NPS) of the patient (Mini-Mental State Examination and Neuropsychiatric Inventory) and psychological distress (Sense of Competence Questionnaire, Center for Epidemiological Studies Depression scale and General Health Questionnaire 12-tem version) of the informal caregivers. Determinants for the course of psychological distress were caregivers' age, gender and relationship with the patient, patients' cognition and NPS, participation in a care program and admission to long-term care facilities (LTCF). With linear mixed models, the course over time for psychological distress and its determinants were explored. RESULTS: We included 117 informal caregivers, of whom 23.1% had a high risk for depression and 41.0% were identified to be likely to have mental problems at baseline. We found a stable pattern of psychological distress over time. Higher frequency of NPS, informal caregivers' age between 50 and 70 years and being female or spouse were associated with higher psychological distress. For patients who were admitted to a LTCF during the study psychological distress of the informal caregivers improved. CONCLUSIONS: GPs should focus on NPS in patients with dementia and on caregivers' psychological distress and be aware of their risk for depression and mental problems, specifically to those who are spouse, female or between 50 and 70 years of age.

Changes in Prescribed Drugs Between Admission and the End of Life in Patients Admitted to Palliative Care Facilities.

BACKGROUND: The aim of prescribing medication in palliative end-of-life care should be symptom control. Data are lacking regarding the prescription of medication at the end of life. AIM: To investigate the prescription of medication in patients at the end of life in palliative care facilities. DESIGN, SETTING, AND PARTICIPANTS: An observational multicenter study in 7 inpatient palliative care facilities. Participants were adults with an estimated life expectancy of less than 3 months. The study was conducted from February 1, 2012, to January 1, 2013. RESULTS: A total of 155 patients were enrolled. On average, patients were prescribed 6.1 drugs at the moment of admission and 4.6 drugs on the day of death. The prescription of analgesics, psycholeptics, and drugs for functional gastrointestinal disorders increased from admission until death. In general, these are drug classes prescribed for symptom control. All other drug classes decreased between admission and the day of death, including different drug classes for the treatment of comorbid disease, such as anticoagulants, beta-blocking agents, drugs used in diabetes, and lipid-modifying agents. CONCLUSIONS AND RELEVANCE: A reduction in the total amount of medication is seen between admission and death in the palliative care facilities. Although there is an increase in prescribed symptom-specific medication and a reduction in medication prescribed for comorbid disease, there are still patients dying with medication not used for symptom control. This increases pill burden and indicates that physicians need to develop guidelines and educational programs for decreasing medication for comorbidities at the end of life.

Prevalence and Correlates of Neuropsychiatric Symptoms in Nursing Home Patients With Young-Onset Dementia: The BEYOnD Study.

OBJECTIVE: Young-onset dementia (YOD) is defined as dementia that develops before the age of 65. Neuropsychiatric symptoms (NPS) have important clinical consequences for patients and their family members. To date, knowledge about the prevalence and correlates of NPS in YOD is limited, but essential to establish specific tailored care for patients with YOD. The aim of this study was to explore the prevalence and correlates of NPS in nursing home residents with YOD. DESIGN/SETTING: Cross-sectional cohort study in Dutch long-term care facilities providing specialized care for YOD. PARTICIPANTS: Participants included 230 institutionalized patients with YOD. MEASUREMENTS: NPS were assessed using the Cohen-Mansfield Agitation Inventory (CMAI) and the Neuropsychiatric Inventory-Nursing Home version (NPI-NH). The influence of gender, dementia severity, type of dementia, and disease awareness on clusters of relevant NPS was investigated using multivariate logistic regression analysis and subsequently corrected for the possible confounders of age, duration of institutionalization, and psychoactive medication use. RESULTS: Ninety percent of the nursing home residents with YOD showed 1 or more neuropsychiatric symptoms, 88% showed significant agitation, and 56% showed relevant apathy. No gender differences were found. Although physically aggressive behavior, non-physically aggressive behavior, and apathy were more common in patients with (very) severe cognitive decline (Global Deterioration Scale [GDS] stage 6-7), verbally agitated behavior was common in patients in all except the most severe stages of dementia (GDS 2-6). Apathy was more prevalent in alcohol-related dementia. Low levels of awareness were associated with more physically aggressive behavior and aberrant motor behavior. CONCLUSION: The prevalence of NPS was high and was associated with the severity and type of dementia and disease awareness. Agitation and apathy are the most important symptoms to focus on in YOD. The high prevalence of NPS supports the idea of care delivery in special care units. Further research is needed on potentially influencing environmental correlates of NPS in YOD.

Are asthma patients at increased risk of clinical depression? A longitudinal cohort study.

OBJECTIVE: In this study, we assessed whether adult patients with asthma are more likely to be diagnosed with depression than diabetes patients or "healthy" controls during follow-up in primary care. METHODS: Data from the Nijmegen Continuous Morbidity Registration were used to assess the risk for a first depression. Patients with asthma were compared with patients with diabetes and with two healthy controls matched on age, gender, socioeconomic status and attending general practice. With Cox proportional hazard analysis, we compared the risk of depression between these groups. These analyses were corrected for relevant covariates including a time-depending variable for multimorbidity. Explorative subgroup analyses were done for age, gender, socioeconomic status and multimorbidity. RESULTS: Cumulative incidence of depression in asthma patients was 5.2%, in DM patients 4.1% and in control subjects 3.3%. The hazard ratios for a first episode of depression in the asthma patients (n = 795) compared to DM patients (n = 1033) and control subjects after correction for covariates were 1.11 (95% CI 0.60-2.04) and 1.18 (95% CI 0.78-1.79), respectively. Exploratory analyses showed that asthma patients without multimorbidity were at higher risk for a depression compared to reference groups, while asthma patients with multimorbidity were at lower risk for depression. CONCLUSION: Asthma patients were not more likely to be diagnosed with a first depression compared to "healthy" control subjects or diabetes patients. The influence of multimorbidity on depression risk in asthma patients warrants further study.

The Effect of Comorbidity on Glycemic Control and Systolic Blood Pressure in Type 2 Diabetes: A Cohort Study with 5 Year Follow-Up in Primary Care.

AIMS: To explore the longitudinal effect of chronic comorbid diseases on glycemic control (HbA1C) and systolic blood pressure (SBP) in type 2 diabetes patients. METHODS: In a representative primary care cohort of patients with newly diagnosed type 2 diabetes in The Netherlands (n = 610), we tested differences in the five year trend of HbA1C and SBP according to comorbidity profiles. In a mixed model analysis technique we corrected for relevant covariates. Influence of comorbidity (a chronic disease already present when diabetes was diagnosed) was tested as total number of comorbid diseases, and as presence of specific disease groups, i.e. cardiovascular, mental, and musculoskeletal disease, malignancies, and COPD. In subgroup effect analyses we tested if potential differences were modified by age, sex, socioeconomic status, and BMI. RESULTS: The number of comorbid diseases significantly influenced the SBP trend, with highest values after five years for diabetes patients without comorbidity (p = 0.005). The number of diseases did not influence the HbA1C trend (p = 0.075). Comorbid musculoskeletal disease resulted in lower HbA1C at the time of diabetes diagnosis, but in higher values after five years (p = 0.044). Patients with cardiovascular diseases had sustained elevated levels of SBP (p = 0.014). Effect modification by socioeconomic status was observed in some comorbidity subgroups. CONCLUSIONS: Presence of comorbidity in type 2 diabetes patients affected the long-term course of HbA1C and SBP in this primary care cohort. Numbers and types of comorbidity showed differential effects: not the simple sum of diseases, but specific types of comorbid disease had a negative influence on long-term diabetes control parameters. The complex interactions between comorbidity, diabetes control and effect modifiers require further investigation and may help to personalize treatment goals.

Rhinosinusitis in morbidity registrations in Dutch General Practice: a retro-spective case-control study.

BACKGROUND: There is only limited accurate data on the epidemiology of rhinosinusitis in primary care. This study was conducted to assess the incidence of acute and chronic rhinosinusitis by analysing data from two Dutch general practice registration projects. Several patient characteristics and diseases are related to the diagnosis rhinosinusitis. METHODS: The Continuous Morbidity Registration (CMR) and the Transitionproject (TP) are used to analyse the data on rhinosinusitis in primary practice. Both registries use codes to register diagnoses. RESULTS: In the CMR 3244 patients are registered with rhinosinusitis and in the TP 5424 CMR: The absolute incidence of (acute) rhinosinusitis is 5191 (18.8 per 1000 patient years). Regarding an odds ratio of 5.58, having nasal polyps is strongest related to rhinosinusitis compared to the other evaluated comorbidities. A separate code for chronic rhinosinusitis exists, but is not in use. TP: Acute and chronic rhinosinusitis are coded as one diagnosis. The incidence of rhinosinusitis is 5574 or 28.7 per 1000 patient years. Patients who visit their general practitioner with "symptoms/complaints of sinus", allergic rhinitis and "other diseases of the respiratory system" have the highest chances to be diagnosed with rhinosinusitis. Medication is prescribed in 90.6 % of the cases. CONCLUSIONS: Rhinosinusitis is a common diagnosis in primary practice. In the used registries no difference could be made between acute and chronic rhinosinusitis, but they give insight in comorbidity and interventions taken by the GP in case of rhinosinusitis.
