Risk prediction algorithms for prolonged postoperative ileus: A systematic review.

AIM: Prolonged postoperative ileus (PPOI) is common and is associated with a significant healthcare burden. Previous studies have attempted to predict PPOI clinically using risk prediction algorithms. The aim of this work was to systematically review and compare risk prediction algorithms for PPOI following colorectal surgery. METHOD: A systematic literature search was conducted using MEDLINE, Embase, Web of Science and CINAHL Plus. Studies that developed and/or validated a risk prediction algorithm for PPOI in adults following colorectal surgery were included. Data were collected on study design, population and operative characteristics, the definition of PPOI used and risk prediction algorithm design and performance. Quality appraisal was assessed using the PROBAST tool. RESULTS: Eleven studies with 87 549 participants were included in our review. Most were retrospective, single-centre analyses (6/11, 55%) and rates of PPOI varied from 10% to 28%. The most commonly used variables were sex (8/11, 73%), age (6/11, 55%) and surgical approach (5/11, 45%). Area under the curve ranged from 0.68-0.78, and only three models were validated. However, there was significant variation in the definition of PPOI used. No study reported sensitivity, specificity or positive/negative predictive values. CONCLUSION: Currently available risk prediction algorithms for PPOI appear to discriminate moderately well, although there is a lack of validation data. Future studies should aim to use a standardized definition of PPOI, comprehensively report model performance and validate their findings using internal and external methodologies.

Prescription medication use among patients with type 2 diabetes in the United States: 1999-2020.

AIMS: We aimed to examine trends in overall prescription medication use among patients with type 2 diabetes in the United States to provide insights for patient care. MATERIALS AND METHODS: We used nationally representative data from the National Health and Nutrition Examination Survey from 1999 to 2020 and included adult patients with type 2 diabetes. We examined the use of prescription drugs, overall and by drug class, polypharmacy (use of ≥5 medications), and number of medications attributed to specific classes. RESULTS: In the period 2015-2020, the mean patient age was 59.6 (51.0-70.0) years, with 46.8% (43.6-49.9) being female and 57.8% (52.8-62.8) being non-Hispanic White. Among 9489 adults with type 2 diabetes, the prevalence of polypharmacy was high and increased from 35.1% (31.6-38.6) in 1999-2002 to 47.2% (43.7-50.7) in 2003-2006, and further to 51.1% (48.3-53.9) in 2015-2020 (p for trend <0.001). Increasing trends of polypharmacy were found across all population subgroups and across the majority of therapeutic classes. Use of non-cardiometabolic medications was common. Among them, the most common were antidepressants (19.8%), proton pump inhibitors (19.0%) and analgesics (16.2%). Among patients with polypharmacy, approximately 40% of medication use was attributed to non-cardiometabolic medications. CONCLUSIONS: Prescription medication burden and complexity increased substantially among patients with type 2 diabetes, with more than 50% of patients with polypharmacy. Attention should be paid to this escalating medication use and regimen complexity, which requires multidisciplinary and coordinated care.

Trends in Number and Appropriateness of Prescription Medication Utilization among Community-Dwelling Older Adults in the US: 2011-2020.

BACKGROUND: Contemporary data on the quantity and quality of medication use among older adults are lacking. This study examined recent trends in number and appropriateness of prescription medication use among older adults in the US. METHOD: Data from the National Health and Nutrition Examination Survey (NHANES) between 2011 and March 2020 were used and 6336 adult participants aged 65 and older were included. We examined the number of prescription medication, prevalence of polypharmacy (≥5 prescription drugs), use of potentially inappropriate medication (PIM), and use of recommended medications (ACEI/ARBs plus beta-blockers among patients with heart failure and ACEI/ARBs among patients with albuminuria). RESULTS: There has been a slight increase in the prevalence of polypharmacy (39.3% in 2011-2012 to 43.8% in 2017-2020, p for trend= 0.32). Antihypertensive, antihyperlipidemic, antidiabetic medications, and antidepressants are the most commonly used medications. There was no substantial change in the use of PIM (17.0% to 14.7%). Less than 50% of older adults with heart failure received ACEI/ARBs plus beta-blockers (44.3% in 2017-2020) and approximately 50% patients with albuminuria received ACEI/ARBs (54.0 in 2017-2020), with no improvement over the study period. Polypharmacy, older age, female, and lower socioeconomic status generally were associated with greater use of PIM but lower use of recommended medications. CONCLUSIONS: The medication burden remained high among older adults in the US and the appropriate utilization of medications did not improve in the recent decade. Our results underscore the need for greater attentions and interventions to the quality of medication use among older adults.

Efficacy of personalised text message intervention in reducing smoking frequency and amount for non-abstinent smokers: A double-blind, randomised controlled trial.

Background: Emerging evidence supports the efficacy of mobile phone interventions for smoking cessation. However, behaviour changes of smokers who fail to reach abstinence and the related psychological mechanism are still understudied. We aimed to evaluate the efficacy of a behaviour change theory-based smoking cessation intervention delivered through personalised text messages from the perspective of smokers who fail to reach abstinence. Methods: We conducted a two-arm, double-blind, randomised controlled trial, with the intervention group receiving personalised text messages developed specifically for this study, and the control group receiving non-personalised ones related to smoking cessation. These messages were sent over a period of three months. We looked at three outcomes: changes in smoking frequency, in smoking amount, and in protection motivation theory (PMT) construct scores. Results: We obtained smoking cessation results for 722 participants who went through the randomisation process (intervention: 360, control: 362; block randomisation design). Overall, 32.3% of baseline daily smokers in the intervention group and 20.0% in the control group changed to weekly smokers during the follow-up period (P < 0.001), while 43.4% of consistent daily smokers in the intervention group and 32.8% in the control group continuously reduced their smoking amount (P < 0.001). We observed associations between the intrinsic rewards of smoking and changes from daily to weekly smoking, the perceived severity of smoking and reductions in smoking amount, as well as the self-efficacy of quitting and changes from daily to weekly smoking/reductions in smoking amount. Conclusions: We found that a personalised text message-based intervention was more likely to decrease the frequency and amount of smoking in smokers who failed to reach abstinence compared to a non-personalised one. We also explored the possible psychological mechanism of such positive effects. Here we provide evidence for countries to consider the promotion of smoking cessations using behaviour theory-driven personalised text messages, which may be more cost-effective than traditional approaches.

Ex-ante moral hazard and health insurance: Evidence from China's urban residence basic medical insurance scheme.

This study examines whether implementing Urban Residents Medical Insurance Scheme decreased an individual's risky lifestyle behavior before illness, termed ex-ante moral hazard. Ex-ante moral hazard is predicted by the classical economic theory suggesting that health insurance coverage reduces an individual's incentive to take preventive efforts to remain healthy. Studies have provided mixed evidence for this prediction. China's 2006 nationwide social experiment of implementing the Urban Residents Basic Medical Insurance Scheme offers an excellent opportunity for examining the effect of the transition from uninsured to insured on an individual's health behaviors. We exploit the longitudinal dimension of a representative survey data for 2007-2010 and employ the instrumental variable technique, thereby addressing the issue of self-selection into voluntary health insurance schemes. The results do not provide evidence for and contrast the prediction of the ex-ante moral hazard. Significant differences exist between insured and uninsured groups with respect to smoking, drinking habits, and being overweight. People with insurance care more about their health than people without insurance do. The main results still hold if we use alternative estimation methods and other robustness tests.

Perforated appendicitis: The solution to pollution is not dilution.

BACKGROUND: Surgical dogma states that the "solution to pollution is dilution." We hypothesized that withholding irrigation during pediatric Single Incision Laparoscopic Surgery (SILS) appendectomies for perforated appendicitis would decrease postoperative abscess rate. METHODS: From May 2011 to 5/2015, during SILS appendectomies, saline irrigation and suctioning was performed. From June 2015 to 8/2021, only suctioning was performed. The operations and peri-operative management were otherwise identical. We retrospectively reviewed 46 patients in the Irrigation (I) Group and 91 patients in the Non-Irrigation (NI) Group. RESULTS: Abscess rate decreased from 19.6% in Group I to 9.9% in Group NI, but this did not reach statistical significance (p = 0.12). Operative duration was significantly longer in patients who developed postoperative abscesses in Group NI (odds ratio 1.67, p = 0.002) and overall (odds ratio 1.45, p = 0.0002). CONCLUSIONS: Withholding irrigation during SILS appendectomies trended toward a decreased postoperative abscess rate. Increased operative times were associated with postoperative abscess formation.

Policy Updates on Access to and Affordability of Innovative Medicines in China.

INTRODUCTION: In China, efforts to qualify innovative medical products for reimbursement used to be subject to substantial delays after regulatory approval due to fiscal and bureaucratic barriers. In this review, we surveyed the Chinese government's most recent initiatives to improve access to innovative medicines from both the regulatory and the reimbursement aspects, which not only accelerated the launching of drugs in the Chinese market but also expanded the reimbursement coverage of such products. We also provided a discussion of the current challenges. AREAS COVERED: We provided a comprehensive review of the updates in China's national reimbursement listing policies of medicines. EXPERT OPINION: As the most recognized regulatory shortcuts, priority and conditional approvals have expedited the authorization of many innovative medicines. In addition, the national negotiation process was institutionalized to enable timely access to innovative medicines through the National Reimbursement Drug List, leading examples of which were new anticancer drugs. Other impactful reimbursement policies in recent years included dynamic updates of the National Reimbursement Drug List, manufacturer-initiated reimbursement coverage applications, and parallel fund robustness tests and pharmacoeconomic analyses for price estimation. Recent administrative efforts have substantially improved the access to and affordability of innovative medicines in China. Nevertheless, standardized and transparent evidence appraisal processes need to be established for informed decision making in the future.

Integrated Behavioral Health in Pediatric Subspecialty Clinics.

Millions of children and adolescents are living with a chronic condition. It is common for mental and behavioral health challenges to arise during their courses of illness. With the complexity of care needed, pediatric subspecialty providers have recognized the need to integrate behavioral health interventions into practice. Continued research in this area has allowed for focused behavioral interventions, particularly in diabetes and asthma. Adult congenital heart programs have adapted a similar model of care and have shown promising success in promotion of health. More established programs have been in existence for childhood cancer and cystic fibrosis.

The Development of Health Technology Assessment in Asia: Current Status and Future Trends.

Health technology assessment (HTA) has long been employed by many countries around the world, but its adoption in Asia has been slower. Only recently have a growing number of Asian countries started to implement HTA for pricing and reimbursement decisions. The objective of this article is to provide an overview of how HTA has been or is being implemented in Asia within the context of a country's existing-and often complex-coverage, reimbursement, and pricing schemes. Three countries at different stages of HTA implementation were selected as case studies: South Korea, where there is a young yet established HTA program; Japan, where a 3-year HTA pilot program has just concluded; and China, where HTA efforts are underway but have not been formally implemented. Not only do the experiences of these 3 countries well exemplify how the organization and scope of HTA can be customized to meet a country's unique healthcare needs, but they also provide the opportunity to outline some common key challenges that must be overcome to implement and develop HTA competencies and capabilities.

Characteristics and health burden of the undiagnosed population at risk of chronic obstructive pulmonary disease in China.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality in China. However, identifying patients has proved challenging, resulting in widespread under-diagnosis of the condition. We examined the prevalence of COPD diagnosis and COPD risk among adults in urban mainland China, the factors associated with having a COPD diagnosis or COPD risk, and the healthcare resource use and health outcomes of these groups compared with controls. METHODS: Respondents to the 2017 National Health and Wellness Survey in China (n = 19,994) were classified into three groups: 'COPD Diagnosed', 'COPD Risk (undiagnosed)', and Control (unaffected), based on their self-reported diagnosis and Lung Function Questionnaire (LFQ) score. The groups were characterised by sociodemographic, health-related quality of life (HRQoL), productivity impairment, and healthcare resource use. Pairwise comparisons (t tests and chi-squared tests) and multivariable regression analyses were used to investigate factors associated with being at risk of, or diagnosed with, COPD. RESULTS: 3320 (16.6%) respondents had a suspected risk of COPD but did not report receiving a diagnosis. This was projected to 105.3 million people, or 16.9% of adult urban Chinese. Of these respondents with an identified risk, only 554 (16.7%) were aware of COPD by name. Relative to those without COPD, those with a risk of COPD (undiagnosed) had significantly greater healthcare resource use, lower productivity and lower HRQoL not only compared to those without COPD, but also compared to people with a COPD diagnosis. Factors associated with increased odds of being at risk of COPD were older age, smoking, alcohol consumption, overweight BMI, occasional exercise, higher comorbidities, asthma diagnosis, being female, lower education, not being employed, and living in a high pollution province (p < 0.05). CONCLUSIONS: There is a substantial group of individuals, undiagnosed, but living with a risk of COPD, who have impaired HRQoL, lower productivity and elevated healthcare resource use patterns. Case-detection tools such as the LFQ may prove a quick and cost-effective approach for identifying these at-risk individuals for further definitive testing and appropriate treatment in China.

Cost-effectiveness of Osimertinib as a Second-line Treatment in Patients With EGFR-mutated Advanced Non-Small Cell Lung Cancer in China.

PURPOSE: To assess the cost-effectiveness of osimertinib used as a second-line treatment after failure of epidermal growth factor receptor tyrosine kinase inhibitor therapy for advanced non-small cell lung cancer (NSCLC) in China. METHODS: From the perspective of China's health care system, a Markov model was used for estimating the costs and health outcomes of osimertinib and 4 platinum-based chemotherapies, including pemetrexed + platinum (PP), gemcitabine + platinum (GP), docetaxel + platinum (DP), and paclitaxel + platinum (TP). Two scenarios were considered, one in all confirmed patients with T790M-positive disease (scenario 1) and the other in all patients whose disease progressed after epidermal growth factor receptor tyrosine kinase inhibitor therapy, which consisted of patients with T790M-positive or T790M-negative NSCLC (scenario 2). Clinical data for transition probabilities and treatment effects were obtained from published clinical trials. Health care resource utilization and costs were derived from local administrative databases and published literature. Deterministic and probabilistic sensitivity analyses were conducted to assess the uncertainty of the results. FINDINGS: In the base-case analysis, compared with the 4 platinum-based chemotherapies, osimertinib yielded an additional 0.671 to 0.846 quality-adjusted life-year (QALY), with incremental costs of 15,943 to 20,299 USD in scenario 1, and an additional 0.376 to 0.808 QALY with incremental costs of 9710 to 15,407 USD in scenario 2. In the probabilistic sensitivity analysis, the probabilities that osimertinib would be cost-effective were 57.7% in scenario 1 and 58.4% in scenario 2 if the willingness-to-pay threshold were 30,000 USD/QALY, and probabilities would be more than 75 % in both scenarios if the willingness-to-pay threshold were 50,000 USD/QALY. IMPLICATIONS: Osimertinib is likely to be cost-effective when used as a second-line treatment of advanced NSCLC in China based on the latest reimbursement price of osimertinib through National Reimbursement Drug List negotiation.

Disease and disparity in China: a view from stroke and MI disease.

BACKGROUND: The actual distribution of stroke and myocardial infarction (MI) associated with social economic status (SES) among the Chinese population is unclear. We aim to understand the development of disparity in stroke and myocardial infarction (MI) across different income groups in Chinese population. METHODS: Data about stroke and MI disease, income, gender, and areas were obtained from China Chronic Disease and Risk Factor (CCDRF) Survey in 2007, 2010, and 2013. Respondents were categorized into different income groups according to their income rank, disease rate was calculated in each group, and difference in disparities between genders, health behaviors, and areas were further identified. Association of disease prevalence rate and income was verified by logistic regression. Trends in stroke and MI disease prevalence rate across income gradients; trends in the correlation between stroke and MI disease prevalence rate and income over time; variation in stroke and MI disease levels and its disparity across income groups by gender, region, and health behavior. Disease prevalence rate is age-adjusted by using China census 2010 population structure as a standard. RESULTS: Three waves of survey were included, the sample size in each wave was 45,095 (year 2007), 84,117 (year 2010), and 134,962 (year 2013). Four major findings were delivered. First, the stroke and MI prevalence rate of Chinese population increased from 2007 to 2013. Second, for each survey wave, a negative correlation between stroke and MI risk with income was identified, and this correlation became weaker over time. The gap in stroke and MI prevalence rate between the richest people and the poorest people decreased from 2007 (gap = 2.5 percentage points) to 2013 (gap = 1.6 percentage points). Third, the identified health inequality varied across genders, regions, and health behaviors. For example, female population used to face a sharper decline in prevalence rate when income grew, this correlation, however, faded over time. The rural-urban difference in disease risk was found to be the largest in the bottom income group (in 2013, the prevalence rate in urban area was 5%, which was 1.8% higher than rural places), this rural-urban difference converged as income increased. Fourth, conditioning on the smoking behavior, the negative association of income and stroke and MI prevalence rate was identified, however, conditioning on the drinking behavior, the association of income and disease morbidity was inconclusive. CONCLUSION: During 2007 and 2013, the Chinese residents experienced a growth in stroke and MI prevalence rate, meanwhile, the increase in income was associated with a decrease in prevalence rate. However, this health disparity became weaker over time since the prevalence rate was more equally distributed across income gradients as time passed by. Although male population faced a systematically higher stroke and MI disease risk than female, the prevalence disparity in different income groups were similar in both sexes in 2013. In addition, there were also regional differences in inequality in terms of the association of disease and income.

Taking stock of cost-effectiveness analysis of healthcare in China.

INTRODUCTION: Cost-effectiveness analysis (CEA) is playing an increasingly important role in informing healthcare decision-making in China. This study aims to review the published literature on CEA in mainland China and describe its characteristics and evolution. We provide recommendations on the future direction of CEA as a methodology and as a tool to support healthcare decision-making in China. METHODS: English-language cost-per-quality-adjusted life-year (QALY) and cost-per-disability-adjusted life-year (DALY) publications relating to mainland China were reviewed using the Tufts Medical Center Cost-Effectiveness Analysis Registry and Global Health Cost-Effectiveness Analysis Registry through 2017. Study features were summarised using descriptive statistics. Changes in study methodology over time were analysed by trend test, and study characteristics influencing the incremental cost-effectiveness ratio (ICER) of cost-per-QALY studies were investigated using logistic regression. RESULTS: 170 studies were identified reporting CEA for mainland China (cost/QALY=125, cost/DALY=45) since 1998. The number and quality of studies has increased over the past two decades, with significantly more cost-per-QALY studies compared with cost-per-DALY studies (p<0.0001) and more studies with authors affiliated with Chinese institutions (p=0.0002). The average quality score was 5.04 out of 7 for cost-per-QALY and 4.70 for cost-per-DALY studies based on Registry reviewers' subjective assessment of overall quality (methods, assumptions and reporting practices). The median ICER reported for interventions for oncology patients was higher (US$26 694 per QALY) than the median ICER reported for all interventions (US$11 503 per QALY). Oncology interventions were associated with the likelihood of reporting higher ICERs than the median ICER (p=0.003). CONCLUSION: The number of English-language published CEA studies relating to China has grown rapidly over the past 20 years. In terms of quality, the China studies compare favourably with international studies, although they remain a small proportion of studies globally.

Dietary Habits and Cognitive Impairment Risk Among Oldest-Old Chinese.

OBJECTIVES: This study examined the longitudinal relationship between dietary habits and cognitive impairment among the oldest-old Chinese. METHOD: Cognitively intact adults aged 80 or older (N = 4,749) came from the Chinese Longitudinal Healthy Longevity Survey. Cognitive impairment was assessed by Mini-mental State Examination. Cox regressions were performed to examine the relationship between dietary habits and cognitive impairment onset during follow-up period of 1998-2012, adjusting for various time-variant and time-invariant individual characteristics. RESULTS: Compared with those who rarely/never consumed fruit, vegetables, meat, and soybean-derived products, participants consuming such products almost every day were 21%, 25%, 17%, and 20% less likely to develop cognitive impairment during follow-up, respectively. Compared with those who rarely/never consumed sugar, participants consuming sugar almost every day were 17% more likely to develop cognitive impairment during follow-up. Consumption of fish, egg, salt-preserved vegetable, tea, and garlic was not found to be associated with cognitive impairment. DISCUSSION: Dietary habits might profoundly impact cognitive functioning among the oldest-old Chinese. This work has limitations pertaining to study design and measure. Future work adopting experimental design and refined dietary measures is warranted to confirm these findings and inform public nutrition practices aiming at preventing cognitive decline among the oldest-old Chinese population.

Cancer diagnosis and care among rural-to-urban migrants in China.

INTRODUCTION: Cancer is a leading cause of death in China. Rural-to-urban migrants are a group of over 260 million people in China sometimes termed the 'floating' population. This study assessed the prevalence of cancer diagnosis and access to needed healthcare by residence and migration status in China. METHODS: We used data from the China Health and Retirement Longitudinal Survey, a nationally representative population-based random sample of adults age 45 years and older and their spouses in China. We used multivariable logistic regressions to compare outcomes among rural-to-urban migrants, local urban residents and local rural residents after adjusting for province of residence, socioeconomic status and demographic characteristics. RESULTS: The sample included 7335 urban residents, 9286 rural residents and 3255 rural-to-urban migrants. Prevalence of cancer diagnosis was 9.9 per 1000 population among rural-to-urban migrants (95% CI 6.5 to 15.1 per 1000 population). Rural-to-urban migrants had higher tobacco use (OR=2.01; 95% CI 1.59 to 2.56, p<0.001), lower use of a health check-up (OR=0.57; 95% CI 0.48 to 0.67, p<0.001) and lower prevalence of diagnosed cancer (OR=0.41; 95% CI 0.18 to 0.95, p=0.037) than urban residents. Among participants with diagnosed cancer, residence and migration status were not predictive of foregoing needed healthcare, but were predictive of diagnosis with a screen-detectable tumour (ie, breast, colon, prostate or cervical cancer) (OR=0.17; 95% CI 0.05 to 0.63, p=0.007 for rural residents; OR=0.34; 95% CI 0.09 to 1.22, p=0.098 for rural-to-urban migrants, compared with urban residents). CONCLUSION: Rapid and large migration is still a driving force transitioning China. Due to some remaining dual policy settings in favour of local residents, rural migrants tend to use lower primary care and preventive health check-ups in general, and diagnosis of screen-detectable tumours in particular, leading to potentially higher risk of missing early diagnosis of cancers. Closing gaps in diagnosis of screen-detectable tumours could increase treatment and improve cancer outcomes.

Long-Term Effects of Famine on Chronic Diseases: Evidence from China's Great Leap Forward Famine.

We evaluate the long-term effects of famine on chronic diseases using China's Great Leap Forward Famine as a natural experiment. Using a unique health survey, we explore the heterogeneity of famine intensity across regions and find strong evidence supporting both the adverse effect and the selection effect. The two offsetting effects co-exist and their magnitudes vary in different age cohorts at the onset of famine. The selection effect is dominant among the prenatal/infant famine-exposed cohort, while the adverse effect appears dominant among the childhood/puberty famine-exposed cohort. The net famine effects are more salient in rural residents and non-migrants subsamples. Gender differences are also found, and are sensitive to smoking and drinking behaviors. Our conclusion is robust to various specifications. Copyright © 2016 John Wiley & Sons, Ltd.

Health Insurance and Health Status: Exploring the Causal Effect from a Policy Intervention.

Whether health insurance matters for health has long been a central issue for debate when assessing the full value of health insurance coverage in both developed and developing countries. In 2007, the government-led Urban Resident Basic Medical Insurance (URBMI) program was piloted in China, followed by a nationwide implementation in 2009. Different premium subsidies by government across cities and groups provide a unique opportunity to employ the instrumental variables estimation approach to identify the causal effects of health insurance on health. Using a national panel survey of the URBMI, we find that URBMI beneficiaries experience statistically better health than the uninsured. Furthermore, the insurance health benefit appears to be stronger for groups with disadvantaged education and income than for their counterparts. In addition, the insured receive more and better inpatient care, without paying more for services. Copyright © 2015 John Wiley & Sons, Ltd.

The impact of the urban resident basic medical insurance on health services utilisation in China.

BACKGROUND: The Urban Resident Basic Medical Insurance (URBMI), launched in 2007 by the State Council, aims to cover around 420 million urban residents in China. OBJECTIVE: This study aimed to assess the impact of URBMI on health services access (especially inpatient utilisation) in urban China. METHODS: Data was drawn from the recent four-wave URBMI Survey (2008-2011). Probit and recursive bivariate probit models have been adopted to handle the possible endogeneity of medical insurance in the utilisation equations. RESULTS: Based on the preferred results from the unbalanced four-wave panel data, we found that the URBMI had significantly increased the likelihood of receiving inpatient treatment in the past year. However, the insurance effect on reducing the refused hospitalisation was insignificant. Finally, the URBMI had also increased the probability of using outpatient services in the past 2 weeks, although the insurance reimburses mainly against critical outpatient care. CONCLUSIONS: Given that it is still early days for the URBMI scheme, the positive effect on health services utilisation is appreciable.

The burden of illness for patients with viral hepatitis C: evidence from a national survey in Japan.

OBJECTIVE: Viral hepatitis C (HCV) affects 170 million patients worldwide and 2 million patients in Japan. The objective of the current study was to examine the burden of HCV in Japan from a patient's perspective. METHODS: Using data from the 2008 and 2009 Japan National Health and Wellness Surveys, patients who reported an HCV diagnosis (n = 306) were compared with a propensity-score-matched control group (n = 306) on measures of quality of life (using the Medical Outcomes Study 12-Item Short Form Survey Instrument version 2), work productivity (using the Work Productivity and Activity Impairment questionnaire), and health-care resource use. All analyses applied sampling weights to project to the population. RESULTS: Prior to matching, patients with HCV had higher rates of hepatocellular carcinoma (4.88% vs. 0.02%) and cirrhosis (12.20% vs. 0.11%) than did subjects without HCV. The propensity-matching process eliminated differences between the two groups on demographics and patient characteristics. The postmatching analysis found significantly lower levels of quality of life for patients with HCV as measured by bodily pain (72.07 vs. 76.28), general health (44.64 vs. 48.61), and mental health (66.50 vs. 70.32) (all Ps < 0.05). Furthermore, compared with the matched group, the HCV group had significantly higher workplace absenteeism (8.59% vs. 4.12%), overall work impairment (26.08% vs. 17.32%), and health-care provider visits in the past 6 months (14.80 vs. 9.74). CONCLUSIONS: The results of this study suggest that HCV can be a substantial burden on patients in terms of quality of life in both physical and mental health measures. In addition, HCV can be a significant cost driver in terms of health-care use and lost productivity.

Comorbid Conditions in Patients With Metastatic Colorectal Cancer.

BACKGROUND: Patients with metastatic colorectal cancer (mCRC) often have other medical conditions that may impact treatment decisions, prognoses and quality of care. We aimed to assess co-existing medical conditions in the mCRC patient population. This retrospective cohort study used linked medical and pharmacy claims data from two US-based Medstat MarketScan claims databases and identified patients with newly diagnosed mCRC between January 2005 and June 2008. METHODS: Patient data were analyzed for comorbid conditions and medication use in the year prior to diagnosis of mCRC. Univariate analyses were conducted to compare the comorbid conditions between patients aged ≥ 65 and < 65 years old. In total, 12 648 patients aged ≥ 18 years were identified. The study was evenly populated by gender and age above and below 65, and most patients had a primary diagnosis of colon cancer (70.1%). RESULTS: The most prevalent comorbidity was cardiovascular disease (CVD) (55.7% of patients) including hypertension (40.8%), cardiac dysrhythmia (14.2%), coronary artery disease (13.5%), congestive heart failure (7.2%) and arterial and venous thromboembolism (6.2% and 4.6%, respectively). Most comorbidities were significantly more prevalent in patients ≥ 65 years of age, particularly with respect to CVD (67.9% versus 42.5%, respectively; P < 0.0001). Additionally, nearly half (49.7%) of the patients received antihypertensive agents and many patients were prescribed more than one class of medications prior to mCRC diagnosis. CONCLUSIONS: Comorbid medical conditions, particularly CVDs, are common in patients with mCRC, which could increase the complexity of patient management. This should be a consideration integral to the selection of the most appropriate treatment for individual patients.
