Risk of psoriatic arthritis depending on age: analysis of data from 65 million people on statutory insurance in Germany

ObjectivesThis study aims to provide a comprehensive analysis of the age-dependent risk of psoriatic arthritis (PsA). For this purpose, it focuses on the varying incidences within the different age groups.MethodsThe data were collected as part of the morbidity-based risk adjustment of the statutory health insurance companies in Germany. This survey recorded the International Statistical Classification of Diseases and Related Health Problems (ICD)-coded diagnoses of 65 million German citizens. Our population-based study used these raw data to calculate the prevalence of PsA in the first step. Subsequently, we employed a new approach for the estimation of the age-specific and sex-specific incidence of PsA.ResultsThe age-specific and sex-specific incidence of PsA showed a continuous increase with rising age until it peaked slightly before the age of 60 and declined thereafter. The maximum value was higher in women (40 per 100 000 py) than in men (30 per 100 000 py). Furthermore, the incidence rate tends to climb over the survey period.ConclusionsThe data sets identified an unexpected high incidence. A meta-analysis by Scotti et al and other recent population-based studies served as a reference for the comparison. The pattern of the age-specific incidence illustrated that the risk for PsA disease shows considerable variations depending on age.

ABSTRACTObjectiveThe aim of this study was to analyze retrospectively the earthquake-induced injuries caused by the October 2015 Hindu Kush earthquake in Pakistan. This is the first population-based study to assess epidemiologically earthquake-induced injuries in the Hindu Kush region, one of the world’s most mountainous and seismically active regions. Unfortunately, only limited studies have investigated the earthquake-induced injuries and deaths in the region epidemiologically.MethodsThe 5 worst affected districts were selected according to the highest number of deaths and injuries recorded. A total of 1,790 injuries and 232 deaths were reported after the 2015 earthquake. In our study area, 391 persons were recorded and verified to have been injured as a result of the earthquake. We attempted to investigate all of the 391 injured people, but the final study looked at 346 subjects because the remaining 45 subjects could not be traced because of the non-availability of their complete records and their refusal to participate in the study.ResultsUsing the International Statistical Classification of Diseases and Related Health Problems, 10th revision (ICD 10), we found that the highest number – 20.23% (70 of 346) – of injuries in the earthquake fall in the class of “Injuries to an unspecified part of trunk, limb, or body region (T08-T14).” The class of “Injuries to knee and lower leg (S80-S89),” which count 15.61% (54 out of 346), followed it, and “Injuries involving multiple body regions (T00-T07)” were making 14.74% of total injuries (51 out of 346).ConclusionIn times of natural disasters like earthquakes, collecting and analyzing real-time data can be challenging. Therefore, a retrospective data analysis of deaths and injuries induced by the earthquake is of high importance. Studies in these emerging domains will be crucial to initiate health policy debates and to prevent and mitigate future injuries and deaths.

Years Lived With Disability

ObjectiveBack pain is the leading cause for years lived with disability globally and among the main reasons for sickness absence (SA) and disability pension (DP). The objective of this study was to explore the occurrence of SA and DP and to estimate productivity losses among individuals with back pain compared with among matched population-based references.DesignExplorative prospective cohort study using register microdata.Participants and settingA total of 23 176 people, aged 19–60 years, with a first visit to inpatient or specialised outpatient healthcare for back pain (International Statistical Classification of Diseases and Related Health Problems code M54) in 2010 in Sweden and a matched population-based reference group (n=115 880).OutcomesLong-term SA (in SA spells >14 days) and DP and productivity losses, measured in € (2018 prices) by multiplying the SA and DP net days by the societal cost of each such day.ResultsIn the back-pain group, 42% had SA or DP days; in the reference group, the corresponding proportion was 15%. Productivity loss per patient with back pain was €8928 during the 12-month follow-up period; in the reference group, it was €3499 (p<0.0001).ConclusionsSA and DP, leading to excess productivity losses among people with back pain, reflect the challenges these patients are facing to maintain their work capacity. Interventions to promote that individuals with back pain remain in paid work should be a priority in order to address the high costs.

Objectives: Invasive treatment of infrainguinal intermittent claudication is controversial, and long-term outcomes are scarce. The study aim was to evaluate 8 years results regarding new vascular interventions on index and contralateral limb, hospitalization, mortality, and amputation in 775 patients revascularized for infrainguinal intermittent claudication in 2009. Methods: Data on new vascular interventions retrieved from the Swedish vascular register (Swedvasc) were linked to the Inpatient Register and Cause of Death Register with information on hospitalizations, primary discharge diagnoses according to the 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-10), deaths, causes of death, and amputations. Results: During 8 years of follow-up, 486 new vascular interventions were performed. Patients were admitted for a total of 4662 hospitalizations and spent 25,970 days in hospital. Between 79% and 99% of surviving subjects were hospitalized each year. During follow-up, 311 (40.1%) patients died. The most common causes of hospitalization and death were cerebrovascular disease, ischemic heart disease, or other diseases of the circulatory system, causing 47.5% of hospitalizations and 42.4% of deaths. Seventy-seven major lower limb amputations were performed in 52 patients. Conclusion: As patients undergoing invasive treatment of infrainguinal intermittent claudication have high morbidity and mortality, during 8 years of follow-up, the indication for invasive treatment should be carefully weighed against concomitant comorbidities and the timing of this treatment optimized with regard to the patient’s possibilities to enjoy positive treatment effects on quality of life.

Objective.To estimate incremental costs for patients with psoriasis/psoriatic arthritis (PsO/PsA) compared to population-based referents free from PsO/PsA and estimate costs attributable specifically to PsO/PsA.Methods.Patients were identified by International Classification of Diseases, 10th ed., codes for PsO/PsA using information from 1998 to 2007 in the Skåne Healthcare Register, covering healthcare use for the population of the Skåne region of Sweden. For each patient, 3 population-based referents were selected. Data were retrieved from Swedish registers on healthcare, drugs, and productivity loss. The human capital method was used to value productivity losses. Mean annual costs for 2008 to 2011 were assessed from a societal perspective.Results.We identified 15,283 patients fulfilling the inclusion criteria for PsO [n = 12,562, 50% women, mean age (SD) 52 (21) yrs] or PsA [n = 2721, 56% women, mean age 54 (16) yrs] and included 45,849 referents. Mean annual cost per patient with PsO/PsA was 55% higher compared to referents: €10,500 vs €6700. The cost was 97% higher for PsA compared to PsO. Costs due to productivity losses represented the largest share of total costs, ranging from 52% for PsO to 60% for PsA. Biological drug costs represented 10% of the costs for PsA and 1.6% for PsO. The proportion of cost identified as attributable to PsO/PsA problems was greatest among the patients with PsA (drug costs 71% and healthcare costs 31%).Conclusion.Annual mean incremental societal cost per patient was highest for PsA, mainly because of productivity losses and biological treatment. A minor fraction of the costs were identified as attributable to PsO/PsA specifically, indicating an increased morbidity in these patients that needs to be further investigated.

AbstractInfection is a common cause for an outpatient visit for young children. Pivalate-conjugated antibiotics (PCAs) are often used for these patients in Japan. However, a few case reports have shown that PCAs can provoke hypoglycemia in children, but no larger study has shown that PCAs increase the risk of hypoglycemia. The current study was performed as a retrospective review of children aged 1 month to 5 years old with at least once prescription of PCAs or other beta-lactam antibiotics from January 2011 to December 2013, using a medical and pharmacy claims database. Hypoglycemia was defined based on the International Statistical Classification of Diseases and Related Health Problems 10th Revision code or prescription of 10% or 20% glucose injection, and the incidence of hypoglycemic events was investigated. Logistic regression analysis was performed to examine the risk of hypoglycemia with PCAs compared with control antibiotics. The study cohort contained 179,594 eligible patients (male: 52.2%, mean age: 3.2 years). The numbers of prescriptions were 454,153 and 417,287 for PCAs and control antibiotics, respectively. Multivariate analysis showed that PCAs were associated with hypoglycemia (adjusted OR 1.18, 95% CI 1.12 to 1.24, P < 0.01), and the risk of hypoglycemia was also significantly increased with use of PCAs for ≤7 days (adjusted OR 1.17, 95% CI 1.11 to 1.24, P < 0.01). These results suggest that prescription of PCAs to young children should be avoided, even for a short time period.

BACKGROUNDHigh-quality cost estimates for hospital-acquired Clostridium difficile infection (CDI) are vital evidence for healthcare policy and decision-making.OBJECTIVETo evaluate the costs attributable to hospital-acquired CDI from the healthcare payer perspective.METHODSWe conducted a population-based propensity-score matched cohort study of incident hospitalized subjects diagnosed with CDI (those with the International Statistical Classification of Diseases and Related Health Problems, 10th Revision, Canada code A04.7) from January 1, 2003, through December 31, 2010, in Ontario, Canada. Infected subjects were matched to uninfected subjects (those without the code A04.7) on age, sex, comorbidities, geography, and other variables, and followed up through December 31, 2011. We stratified results by elective and nonelective admissions. The main study outcomes were up-to-3-year costs, which were evaluated in 2014 Canadian dollars.RESULTSWe identified 28,308 infected subjects (mean annual incidence, 27.9 per 100,000 population, 3.3 per 1,000 admissions), with a mean age of 71.5 years (range, 0–107 years), 54.0% female, and 8.0% elective admissions. For elective admission subjects, cumulative mean attributable 1-, 2-, and 3-year costs adjusted for survival (undiscounted) were $32,151 (95% CI, $28,192–$36,005), $34,843 ($29,298–$40,027), and $37,171 ($30,364–$43,415), respectively. For nonelective admission subjects, the corresponding costs were $21,909 ($21,221–$22,609), $26,074 ($25,180–$27,014), and $29,944 ($28,873–$31,086), respectively.CONCLUSIONSHospital-acquired CDI is associated with substantial healthcare costs. To the best of our knowledge, this study is the first CDI costing study to present longitudinal costs. New strategies may be warranted to mitigate this costly infectious disease.Infect Control Hosp Epidemiol 2016;37:1068–1078

Background: There is variation in the risk of malignancy in dermatomyositis (DM) and polymyositis (PM) in the existing literature. Objective: To conduct a meta-analysis to estimate the risk of malignancy in DM and PM as compared with the general population. Methods: Medline and Embase Database abstracts were searched through August 2014 using the search terms myositis, neoplasms, and paraneoplastic syndromes. Population-based, observational studies in English were included. Meta-analyses were conducted using random-effects models. Results: A total of 5 studies with 4538 DM or PM patients were included in the analysis. The overall relative risk was 4.66 for DM and 1.75 for PM. By gender, the standardized incidence ratio (SIR) of malignancy among DM patients was 5.29 for males and 4.56 for females; the SIR of malignancy among PM patients was 1.62 for males and 2.02 for females. By time since diagnosis, the SIR of malignancy among DM patients was 17.29 in the first year, 2.7 between 1 and 5 years, and 1.37 after 5 years. By age group, the SIR among DM patients was 2.79 for patients between 15 and 44 years and 3.13 beyond 45 years. Conclusions: Both DM and PM are associated with increased risk of malignancy, but the risk is higher in DM. The risk of malignancy is present in both genders and all age groups and is highest in the first year after diagnosis but persists beyond the fifth year in DM. Adults should be evaluated for malignancy at diagnosis, followed by long-term surveillance.

OBJECTIVE: To measure the frequency of diseases related to latent tuberculosis infection (LTBI) and tuberculosis (TB), we assessed the agreement between diagnosis codes for TB or LTBI in electronic health records (EHRs) and insurance claims for the same person.METHODS: In a US population-based, retrospective cohort study, we matched TB-related Systematized Nomenclature of Medicine–Clinical Terms (SNOMED CT) EHR codes and International Statistical Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) claims codes. Furthermore, LTBI was identified using a published ICD-based algorithm and all LTBI- and TB-related SNOMED CT codes.RESULTS: Of people with the 10 most frequent TB-related claim codes, 50% did not have an exact-matched EHR code. Positive tuberculin skin test was the most frequent unmatched EHR code and people with the 10 most frequent TB EHR codes, 40% did not have an exact-matched claim code. The most frequent unmatched claim code was TB screening encounter. EHR codes for LTBI matched to claims codes for TB testing; pulmonary TB; and nonspecific, positive or adverse tuberculin reaction.CONCLUSION: TB-related EHR codes and claims diagnostic codes often disagree, and people with claims codes for LTBI have unexpected EHR codes, indicating the need to reconcile these coding systems.

BackgroundPrevious studies have suggested that socio-environmental factors interact with genetic risk in the genesis of schizophrenia. This study aimed to investigate the relationship between income, income inequality and schizophrenia and its heterogeneity among different geographic scales and subgroups.MethodsWe used data from the Second China National Sample Survey on Disability (2006). The sample consisted of 1 909 205 participants aged 18 years or older. Individuals who were suspected to be psychiatrically disabled were administered the WHO Disability Assessment Schedule, Version II and the International Statistical Classification of Diseases, Tenth Revision Symptom Checklist for Mental Disorders by trained clinical psychiatrists to diagnose schizophrenia. Gross household income per capita was used to calculate the Gini coefficient to measure income inequality. Multilevel logistic regression with cross-level interaction was applied to examine the association of income, income inequality and schizophrenia.ResultsA total of 7 628 persons (0.40%) were identified as having schizophrenia. Income was independently associated with schizophrenia. At the province level, greater income inequality was significantly associated with a higher risk of schizophrenia (OR, 1.03; 95% CI 1.00 to 1.06), and no significant association was observed at the county level. The analysis with cross-level interaction showed that the association at the province level was most pronounced in the highest income quartile (OR, 1.02; 95% CI 1.00 to 1.03).ConclusionThe significant association between income and schizophrenia was consistent with the absolute income hypothesis. The adverse effect of income inequality on the risk of schizophrenia starts to operate at a larger area level, and it is more pronounced for the affluent population in China. This finding further supports the relative income hypothesis and social causation pathway for schizophrenia and calls attention to the vulnerability of high-income groups.

The Impact

Introduction: Waist-to-heightratio (WHtR) has been shown to be useful global screening tool forcardiovascular disease (CVD) in the recent meta-analysis. The impact of WHtR on the risks of CVD by age is not well known. Hypothesis: We assessed whether the association between WHtR and the risks of CVD was different by age categories. Methods: This study is a population-based cohort study in an urban area of Japan. Study participants comprised 5,488 Japanese urban residents (2,600 men and 2,888 women) aged 30-83 years with no history of CVD. At baseline (1989–1994), waist circumference was measured at the umbilical level and height with bare feet was measured. WHtR was calculated as waist circumference (cm) divided by height (cm). The criteria of myocardial infarction were based on the WHO Monitoring of Trends and Determinants in Cardiovascular Disease Projects. In addition to myocardial infarction, we also evaluated coronary angioplasty, coronary artery bypass grafting and sudden cardiac death, all of which were defined as coronary heart disease (CHD). A stroke was defined according to criteria from the US National Survey of Stroke and confirmed by computed tomography. We stratified participants by sex and age groups (30–49, 50–69 and 70–83 years). The Cox proportional hazard ratios (HRs) and 95% confidence intervals (95% CIs) for CVD according to the quartiles of WHtR were calculated after adjustment for age, smoking and drinking status. Results: During the follow-up period (13.0 years in average), 428 CVD events (184 CHD and 244 strokes) were observed. Men with the highest quartile of WHtR aged 50–69 years had significantly increased the risks of CVD and CHD, compared with the lowest quartile; the HRs (95% CIs) were 1.81 (1.13–2.90) and 2.47 (1.17–5.20), respectively. There were statistically significant linear increases in the HRs of CVD ( p for trend =0.01), CHD ( p for trend =0.02) and cerebral infarction ( p for trend =0.03) in this group. Women with the highest quartile of WHtR aged 50–69 years had significantly increased the risks of stroke; the HRs (95% CIs) was 2.43 (1.01–5.84). There were statistically significant linear increases in the HRs of CVD ( p for trend =0.04) and stroke ( p for trend =0.04) in this group. However, the similar results were not observed in the other age groups in both sexes. We observed a significant interaction between age groups and WHtR categories for the risks of CVD in men ( p for interaction=0.02). Conclusions: The association between WHtR and CVD was different among age groups. WHtR could be useful to predict the risks of CVD in middle aged men and women.
