- Background. Chronic kidney disease (CKD) is common, but the frequency of albuminuria testing and referral to nephrology care has been difficult to measure. We here characterize CKD prevalence and recognition in a complete healthcare utilization cohort of the Stockholm region, in Sweden. Methods. We included all adult individuals (n = 1 128 058) with at least one outpatient measurement of IDMS-calibrated serum creatinine during 2006-11. Estimated glomerular filtration rate (eGFR) was calculated via the CKD-EPI equation and CKD was solely defined as eGFR <60 mL/min/1.73 m(2). We also assessed the performance of diagnostic testing (albuminuria), nephrology consultations, and utilization of ICD-10 diagnoses. Results. A total of 68 894 individuals had CKD, with a crude CKD prevalence of 6.11% [95% confidence interval (CI): 6.07-6.16%] and a prevalence standardized to the European population of 5.38% (5.33-5.42%). CKD was more prevalent among the elderly (28% prevalence >75 years old), women (6.85 versus 5.24% in men), and individuals with diabetes (17%), hypertension (17%) or cardiovascular disease (31%). The frequency of albuminuria monitoring was low, with 38% of diabetics and 27% of CKD individuals undergoing albuminuria testing over 2 years. Twenty-three per cent of the 16 383 individuals satisfying selected KDIGO criteria for nephrology referral visited a nephrologist. Twelve per cent of CKD patients carried an ICD-10 diagnostic code of CKD. Conclusions. An estimated 6% of the adult Stockholm population accessing healthcare has CKD, but the frequency of albuminuria testing, nephrology consultations and registration of CKD diagnoses was suboptimal despite universal care. Improving provider awareness and treatment of CKD could have a significant public health impact.

- Background: Primary intracranial tumors are relatively uncommon and heterogeneous, which make them challenging to study. We coupled data from unique Swedish population-based registries in order to deeper analyze the most common intracranical tumor types. Patient characteristics (e.g. comorbidities), care process measures like adherence to national guidelines, healthcare resource use and clinical outcome was evaluated.Materials and methods: A register-based study including several population-based registries for all patients living in Stockholm-Gotland, diagnosed with primary intracranial tumor between 2001 and 2013 was performed. Patient characteristics were captured and investigated in relation to survival, healthcare resource use (inpatient-, outpatient- and primary care) and treatment process.Results: High-grade glioma and meningioma were the most common tumor types and most patients (76%) were above the age of 40 in the patient population (n = 3664). Older age, comorbidity (Elixhauser comorbidity index) and type of tumor (high-grade glioma) were associated with lower survival rate and increased use of healthcare resources, analyzed for patients living in Stockholm (n = 3031). The analyses of healthcare use and survival showed no differences between males and females, when stratifying by tumor types. Healthcare processes were not always consistent with existing national treatment recommendations for patients with high-grade gliomas (n = 474) with regard to specified lead times, analyzed in the Swedish Brain Tumor Registry, as also observed at the national level.Conclusions: Age, comorbidity and high-grade gliomas, but not sex, were associated with decreased survival and increased use of healthcare resources. Fewer patients than aimed for in national guidelines received care according to specified lead times. The analysis of comprehensive population-based register data can be used to improve future care processes and outcomes.

- Concerns have been raised about the abuse potential of pregabalin. Therefore, the aim of our study was to characterize patients dispensed pregabalin at higher than the maximum allowed dose in a cohort study based on data extracted from Swedish national registers. All patients dispensed at least three prescriptions of pregabalin between July 2006 and December 2009 were included (n = 48,550). The daily dose was defined as the amount of pregabalin dispensed divided by the number of days between the second and third dispensings. Associations between sociodemographic and clinical variables and dispensing pregabalin at a dose exceeding the maximum daily allowed dose (600 mg) were investigated in multivariate regression models. Of the patients dispensed pregabalin during the study period, 8.5 % were dispensed a dose that exceeded the maximum daily allowed dose. A previous addictive disorder drug treatment or diagnosis was present in 20 and 31 % of patients dispensed pregabalin within and exceeding the recommended dose range, respectively. Our analysis revealed that those patients at increased risk of being dispensed pregabalin at higher than the maximum allowed dose were male [adjusted odds ratio (aOR) 1.40, 95 % confidence interval (CI) 1.31-1.49], were between 18 and 29 years of age compared with those aged a parts per thousand yen65 years (aOR 1.62, 95 % CI 1.45-1.82), had a low income (aOR 1.24, 95 % CI 1.10-1.40), had epilepsy compared with no diagnosis (aOR 1.41, 95 % CI 1.10-1.81), had a previous substance use disorder treatment or diagnosis (aOR 1.41, 95 % CI 1.31-1.52) or had previously been dispensed high doses of drugs with abuse potential (aOR 1.77, 95 % CI 1.62-1.94). Based on our results we conclude that patients at a high risk of addiction and patients with epilepsy are more likely to be dispensed pregabalin at higher than the maximum approved daily dose.

Tidskriftsartikel (refereegranskat)abstract
- Background: There is limited knowledge on the prevalence of disease in total populations. Such studies have historically been difficult to conduct but the development of health data registers has facilitated large-scale studies on recorded diagnoses in entire regions. The aim of this study was to analyze the prevalence of diagnosis of six common diseases in the Swedish capital region. Methods: The study population included all living persons who resided in Stockholm County, Sweden, on December 31st 2011 (N = 2 093 717). Information on all consultations between 2007 and 2011 was obtained from primary health care, specialist outpatient care and inpatient care. Prevalence was defined as the proportion of individuals with a recorded diagnosis of diabetes, depression, anxiety disorders, hypertension, asthma and chronic obstructive pulmonary disease during the five year period, respectively. Analyses were done by age and gender. Results: Hypertension had the highest five-year prevalence (12.2%), followed by depression (6.6%), diabetes mellitus (6.2%), asthma (5.9%), anxiety disorders/phobia (4.8%), and COPD (1.8%). Diabetes was more common in men (5.3% of women and 7.1% of men) while depression (8.7% in women and 4.4% in men) and anxiety (6.3% in women and 3.4% in men) were considerably more common in women. Smaller gender differences were also found for hypertension (13.0% in women and 11.4% in men), asthma (6.4% in women and 5.4% in men) and COPD (2.1% in women and 1.6% in men). Diabetes, hypertension and COPD increased markedly with age, whereas anxiety, depression and asthma were fairly constant in individuals above 18 years. During one year of observation, more than half of all patients had only been diagnosed in primary health care, with hypertension being the diagnosis with the largest proportion of patients only identified in primary health care (70.6%). Conclusion: The prevalence of common diseases in the population can be estimated by combining data gathered during consecutive years from primary care, specialist outpatient care and inpatient care. However, accuracy of disease prevalence is highly dependent on the quality of the data. The high prevalence of the six diagnoses analysed in this study calls for preventive action to minimize suffering and costs to society.

- There is limited experience and methods for extractions of drug therapy data from electronic health records (EHR) in the hospital setting. We have therefore developed and evaluated completeness and consistency of an automatic versus a semi-automatic extraction procedure applied on prescribing and administration of the TNF inhibitor infliximab using a hospital EHR system in Karolinska University Hospital, Sweden. Using two different extraction methods (automatic and semi-automatic), all administered infusions of infliximab between 2007 and 2010 were extracted from a database linked to the EHR system. Extracted data included encrypted personal identity number (PIN), date of birth, sex, time of prescription/administration, healthcare units, prescribed/administered dose and time of admission/discharge. The primary diagnosis (ICD-10) for the treatment with infliximab was extracted by linking infliximab infusions to their corresponding treatment episode. A total of 13,590 infusions of infliximab were administered during the period of 2007 to 2010. Of those were 13,531 (99.6%) possible to link to a corresponding treatment episode, and a primary diagnosis was extracted for 13,530 infusions. Information on encrypted PIN, date of birth, time of prescription/administration, time of admission/discharge and healthcare unit was complete. Information about sex was missing in one patient only. Calculable information about dosage was extracted for 13,300 (98.3%) of all linked infusions. This methodological study showed the potential to extract drug therapy data in a hospital setting. The semi-automatic procedure produced an almost complete pattern of demographics, diagnoses and dosages for the treatment with infliximab.

- Crohn's disease [CD] and ulcerative colitis [UC] are chronic diseases associated with a substantial utilisation of healthcare resources. We aimed to estimate the prevalence of inflammatory bowel disease [IBD], CD, and UC and to describe and compare healthcare utilisation and drug treatment in CD and UC patients. This was a cross-sectional study of all patients with a recorded IBD diagnosis in Stockholm County, Sweden. Data on outpatient visits, hospitalisations, surgeries, and drug treatment during 2013 were analysed. A total of 13 916 patients with IBD were identified, corresponding to an overall IBD prevalence of 0.65% [CD 0.27%, UC 0.35%, inflammatory bowel disease unclassified 0.04%]; 49% of all IBD patients were treated with IBD-related drugs. Only 3.6% of the patients received high-dose corticosteroids, whereas 32.4% were treated with aminosalicylates [CD 21.2%, UC 41.0%, p < 0.0001]. More CD patients were treated with biologicals compared with UC patients [CD 9.6%, UC 2.9%, p < 0.0001] and surgery was significantly more common among CD patients [CD 3.0%, UC 0.8%, p < 0.0001]. This study indicates that patients with CD are the group with the highest medical needs. Patients with CD utilised significantly more healthcare resources [including outpatient visits, hospitalisations, and surgeries] than UC patients. Twice as many CD patients received immunomodulators compared with UC patients and CD patients were treated with biologicals three times more often. These results highlight that CD remains a challenge and further efforts are needed to improve care in these patients.

- Purpose Validated measures of asthma and eczema at the population level remain a challenge. Our aim was to ascertain if register-based information on asthma/eczema medication can function as a proxy for an asthma/eczema diagnosis and to validate register-based asthma diagnoses. Methods Information was requested on all 0-45-year-old individuals with reported asthma/eczema medication and/or diagnoses in the Swedish Prescribed Drug Register and National Patient Register, between July 2005 and December 2009 (N = 250 691). Medical records for 1952 randomly selected individuals were reviewed to estimate the proportion of individuals with the following: (1) asthma/eczema medication that fulfilled predefined criteria of asthma/eczema (positive predictive value (PPV)) and (2) a register-based asthma diagnosis verified as asthma by predefined criteria. Results Positive predictive value for asthma by predefined criteria ranged between 0.75 (95% CI: 0.70-0.78) to 0.94 (95% CI: 0.91-0.96), depending on age group. In pre-school children, PPV for asthma in combination with obstructive bronchitis was 0.87 (95% CI: 0.83-0.90), and PPV for eczema was estimated to 0.45 (95% CI: 0.38-0.51). Eighty percent of children 0-4.5 years and 99% of children >4.5-17 years with a register-based diagnosis of asthma were verified as asthmatics. Conclusion Asthma medication is a suitable proxy for asthma in older children and adults; the same approach is insufficient for eczema. This validation study of two Swedish registers opens for future large nation-wide register-based studies on asthma. Copyright (C) 2013 John Wiley & Sons, Ltd.
