Understanding the economic,daily functioning,and diabetes management burden of non-severe nocturnal hypoglycemic events in Canada: differences between type 1 and type 2

Objective:

To examine the daily functioning, diabetes management, and economic burden of non-severe nocturnal hypoglycemic events (NSNHEs) in Canada and differences in impacts by diabetes type.

Research design and methods:

A 20-min web-based survey, with items derived from the literature, expert and patient interviews, assessing the impact of NSNHEs, was administered to patients with self-reported diabetes aged ≥18 having an NSNHE in the past month.

Results:

Two thousand, two hundred and seventy-nine Canadian persons with diabetes were screened with 200 respondents meeting criteria and included in the analysis sample. Out of 87 working respondents, 15 reported on average 3.5?h of lost work (absenteeism). The reduction in work productivity (presenteeism) reported was comparable to the impact of arthritis. Other functional impacts included sleep and daily activities. Additionally, respondents’ increased their usual blood sugar monitoring practice, on average, 4.2 (SD?=?7.5) extra tests were conducted in the week following the event and reduced their insulin over the following 4.8 days. Increased healthcare utilization was also reported. Increased costs as a result of NSNHE for lost work productivity, increased diabetes management, and resource utilization was CAD 70.67 per person per year in this sample. Limitations of the study include the biases which are associated with a web-based survey and self-reported data.

Conclusions:

NSNHEs have serious consequences for patients and diabetes management practices. Greater attention to treatments which reduce NSNHEs can have a major impact on improving functioning while reducing the economic burden of diabetes.     

The impact of non-severe hypoglycemic events on daytime function and diabetes management among adults with type 1 and type 2 diabetes

Abstract

Objectives:

To describe daytime non-severe hypoglycemic events (NSHEs), assess their impact on patient functioning and diabetes self-management, and examine if these impacts differ by diabetes type or country.

Methods:

Internet survey to adults with diabetes in the US, UK, Germany, and France.

Results:

Of 6756 screened respondents, 2439 reported a daytime NSHE in the past month. NSHEs occurred while active (e.g., running errands) (45.1%), 29.6% while not active (e.g., watching TV), and 23.8% at work. On average, it took half a day to respond and recover from NSHE. Respondents monitored their glucose 5.7 extra times on average over the following week. On the day of event, type 1 respondents tested significantly more often than type 2 (p?<?0.05). Type 2 were less likely to confirm NSHE with glucose test (p?<?0.001). Following NSHE, 12.6% of respondents reduced total insulin by an average of 7.6 units (SD?=?8.3). Total units and days with reduced dosing was significantly less, whilst number of additional glucose tests and time to recover was significantly longer if NSHE occurred at work (p?<?0.001). Type 1 decreased insulin doses more often (p?<?0.001); however, type 2 decreased a greater number of units (p?<?0.01). Compared with other countries, US respondents were more likely to eat a light or full meal and respondents in France took significantly longer than all other countries to recognize (p?<?0.05), respond to (p?<?0.001), and recover from (p?<?0.001) NSHE, used significantly more monitoring tests the day of (p?<?0.05) and over the subsequent week (p?<?0.001), and decreased their normal insulin dose more (p?<?0.001). Limitations of the study include potential recall bias and selection bias.

Conclusions:

NSHEs are associated with a significant impact on patient functioning and diabetes management.     

Effects of patient-reported non-severe hypoglycemia on healthcare resource use,work-time loss,and wellbeing in insulin-treated patients with diabetes in seven European countries

Abstract

Purpose:

Hypoglycemia is a frequent side effect induced by insulin treatment of type 1 (T1DM) and type 2 diabetes (T2DM). Limited data exist on the associated healthcare resource use and patient impact of hypoglycemia, particularly at a country-specific level. This study investigated the effects of self-reported non-severe hypoglycemic events (NSHE) on use of healthcare resources and patient wellbeing.

Methods:

Patients with T1DM or insulin-treated T2DM diabetes from seven European countries were invited to complete four weekly questionnaires. Data were collected on patient demographics, NSHE occurrence in the last 7 days, hypoglycemia-related resource use, and patient impact. NSHE were defined as events with hypoglycemia symptoms, with or without blood glucose measurement, or low blood glucose measurement without symptoms, which the patient could manage without third-party assistance.

Results:

Three thousand, nine hundred and fifty-nine respondents completed at least one wave of the survey, with 57% completing all four questionnaires; 3827 respondents were used for data analyses. Overall, 2.3% and 8.9% of NSHE in patients with T1DM and T2DM, respectively, resulted in healthcare professional contact. Across countries, there was a mean increase in blood glucose test use of 3.0 tests in the week following a NSHE. Among respondents who were employed (48%), loss of work-time after the last hypoglycemic event was reported for 9.7% of NSHE. Overall, 10.2% (daytime) and 8.0% (nocturnal) NSHE led to work-time loss, with a mean loss of 84.3 (daytime) and 169.6 (nocturnal) minutes among patients reporting work-time loss. Additionally, patients reported feeling tired, irritable, and having negative feelings following hypoglycemia.

Limitations:

Direct comparisons between studies must be interpreted with caution because of different definitions of hypoglycemia severity, duration of the studies, and methods of data collection.

Conclusions:

NSHE were associated with use of extra healthcare resources and work-time loss in all countries studied, suggesting that NSHE have considerable impact on patients/society.     

Hypoglycemia: An overview of fear of hypoglycemia,quality-of-life,and impact on costs

Abstract

Background:

The clinical goal in the treatment of diabetes is to achieve good glycemic control. Tight glycemic control achieved with intensive glucose lowering treatment reduces the risk of long-term micro- and macro-vascular complications of diabetes, resulting in an improvement in quality-of-life for the patient and decreased healthcare costs. The positive impact of good glycemic control is, however, counterbalanced by the negative impact of an increased incidence of hypoglycemia.

Methods:

A search of PubMed was conducted to identify published literature on the impact of hypoglycemia, both on patient quality-of-life and associated costs to the healthcare system and society.

Results:

In people with type 1 or type 2 diabetes, hypoglycemia is associated with a reduction in quality-of-life, increased fear and anxiety, reduced productivity, and increased healthcare costs. Fear of hypoglycemia may promote compensatory behaviors in order to avoid hypoglycemia, such as decreased insulin doses, resulting in poor glycemic control and an increased risk of serious health consequences. Every non-severe event may be associated with a utility loss in the range of 0.0033–0.0052 over 1 year, further contributing to the negative impact.

Limitations:

This review is intended to provide an overview of hypoglycemia in diabetes and its impact on patients and society, and consequently it is not a comprehensive evaluation of all studies reporting hypoglycemic episodes.

Conclusion:

To provide the best possible care for patients and a cost-effective treatment strategy for healthcare decision-makers, a treatment that provides good glycemic control with a limited risk of hypoglycemia would be a welcome addition to diabetes management options.     

Impact of nocturnal hypoglycemic events on diabetes management,sleep quality,and next-day function: results from a four-country survey

Abstract

Objectives:

Non-severe nocturnal hypoglycemic events (NSNHEs) may have a major impact on patients. The objective was to determine how NSNHEs affect diabetes management, sleep quality, functioning, and to assess if these impacts differ by diabetes type or country.

Methods:

An internet survey to adults with diabetes in the US, UK, Germany, and France.

Results:

Of 6756 screened respondents, 1086 reported an NSNHE in the past month. For this last event, respondents with type 2 required significantly more time than type 1 to recognize and respond to the event (1.5 vs 1.1 hours), 25.7% (T1) and 18.5% (T2) decreased their normal insulin dose due to their most recent NSNHE. All respondents were likely to take 1–2 additional self-monitored blood glucose measurements on the day following. NSNHEs were associated with a high proportion of respondents contacting a healthcare professional (18.6% T1, 27.8% T2) reporting they could not return to sleep at night (13.3% T1, 13.4% T2), and tiredness on the day following the event (71.2% for both). Of the respondents working for pay, 18.4% T1 and 28.1% T2 reported being absent from work due to the NSNHE, and a substantial proportion of respondents (8.7% T1, 14.4% T2) also reported missing a meeting or work appointment or not finishing a task on time. Compared with other countries, respondents from France may experience a more substantial impact on diabetes management and daily functioning following an NSNHE. Potential limitations in this study include recall and selection bias; however, these biases are not believed to have impacted findings in any meaningful way.

Conclusions:

NSNHEs are associated with a substantial impact on diabetes management, sleep quality, and next-day functioning.     

Evaluating the length of stay and value of time in a pediatric emergency department with two models by comparing two different albuterol delivery systems

Abstract

Objective:

Asthma is one of the most common childhood illnesses and accounts for a substantial amount of pediatric emergency department visits. Historically, acute exacerbations are treated with a beta agonist via nebulizer therapy (NEB). However, with the advent of the spacer, the medication can be delivered via a metered dose inhaler (MDI?+?S) with the same efficacy for mild-to-moderate asthma exacerbations. To date, no study has been done to evaluate emergency department (ED) length of stay (LOS) and opportunity cost between nebulized vs MDI?+?S. The objective of this study was to compare ED LOS and associated opportunity cost among children who present with a mild asthma exacerbation according to the delivery mode of albuterol: MDI?+?S vs NEB.

Methods:

A structured, retrospective cross-sectional study was conducted. Medical records were reviewed from children aged 1–18 years treated at an urban pediatric ED from July 2007 to June 2008 with a discharge diagnosis International Classification of Disease-9 of asthma. Length of stay was defined: time from initial triage until the time of the guardian signature on the discharge instructions. An operational definition was used to define a mild asthma exacerbation; those patients requiring only one standard weight based albuterol treatment. Emergency department throughput time points, demographic data, treatment course, and delivery method of albuterol were recorded.

Results:

Three hundred and four patients were analyzed: 94 in the MDI?+?S group and 209 in the NEB group. Mean age in years for the MDI?+?S group was 9.57 vs 5.07 for the NEB group (p?<?0.001). The percentage of patients that received oral corticosteroids was 39.4% in the MDI?+?S group vs 61.7% in the NEB group (p?<?0.001). There was no difference between groups in: race, insurance status, gender, or chest radiographs. The mean ED LOS for patients in the MDI?+?S group was 170 minutes compared to 205 minutes in the NEB group. On average, there was a 25.1 minute time savings per patient in ED treatment time (p?<?0.001; 95% CI?=?3.8–31.7). Significant predictors of outcome for treatment time were chest radiograph, steroids, and treatment mode. Opportunity cost analysis estimated a potential cost savings of $213,532 annually using MDI?+?S vs NEB.

Conclusion:

In mild asthma exacerbations, administering albuterol via MDI?+?S decreases ED treatment time when compared to administering nebulized albuterol. A metered dose inhaler with spacer utilization may enhance opportunity cost savings and decrease the left without being seen population with improved throughput.

Limitations:

The key limitations of this study include its retrospective design, the proxy non-standard definition of mild asthma exacerbation, and the opportunity cost calculation, which may over-estimate the value of ED time saved based on ED volume.     

The impact of formal financial inclusion on informal financial intermediation and cash preference: evidence from Africa

This paper examines the effect of formal financial intermediation (inclusion) on informal financial intermediation and the use of cash for economic activities. Using data from the Global Findex 2014, we examine whether the use of formal financial intermediaries reduces cash preference and the use of informal financial intermediaries. Our empirical results show that informal financial intermediation is positively associated with formal financial inclusion. This indicates that the relationship between informal and formal financial intermediation is complementary rather than a trade-off, which demonstrates the importance of informal finance plays in the financial system of Africa. Moreover, the use of formal financial intermediaries significantly reduces the preference for holding cash, implying that a robust financial system infrastructure has the potential of mobilizing excess liquidity in the informal economy of Africa for growth and development.     

The impact of increasing neurological disability of multiple sclerosis on health utilities: a systematic review of the literature

Abstract

Background: Multiple sclerosis (MS) is a debilitating disease, accompanied by neurological symptoms of varying severity. Utilities are a key summary index measure used in assessing health-related quality of life in individuals with MS.

Objectives: To provide a systematic review of the literature on utilities of relapsing-remitting MS (RRMS) and secondary progressive MS (SPMS) patients and to review changes in utilities associated with the increasing neurological disability of different stages of MS, as measured by the Expanded Disability Status Scale (EDSS).

Methods: Employing pre-defined search terms and inclusion/exclusion criteria, systematic searches of the literature were conducted in EMBASE, MEDLINE, PsycINFO, the Health Economic Evaluation Database (HEED), and the NHS Economic Evaluations Database (NHS/EED). Proceedings for the International Society for Pharmacoeconomics and Outcomes Research (ISPOR), the European Society for Treatment and Research in MS (ECTRIMS), the American Society for Treatment and Research in MS (ACTRIMS), and the Latin American Society for Treatment and Research in MS (LACTRIMS) were reviewed in addition to the UK National Institute for Health and Clinical Excellence website and the table of contents of PharmacoEconomics and Value in Health.

Results: This review identified 18 studies reporting utilities associated with health states of MS. Utilities ranged from 0.80 to 0.92 for patients with an EDSS score of 1, from 0.49 to 0.71 for patients with an EDSS score of 3, from 0.39 to 0.54 for patients with an EDSS score of 6.5, and from –0.19 to 0.1 for patients with an EDSS score of 9.

Limitations: Several of the studies reviewed relied on data from patient organizations, which may not be fully representative of the general patient populations. Additionally, the majority of the studies relied on retrospective data collection.

Conclusions: Utilities decrease substantially with increasing neurological disability. Cross-country differences are minimal with utility scores following a similar pattern across countries for patients at similar disease severity levels. This consistency in findings is noteworthy, as there is a reliable evidence base for selecting utility values for economic evaluation analyses. However, more research is needed to explore potential differences in utilities between RRMS and SPMS patients.

The societal impact of pain in the European Union: health-related quality of life and healthcare resource utilization

Abstract

Objectives:

This paper reports on the results of a series of quantitative assessments of the association of severe and frequent pain with health-related quality of life and healthcare resource utilization in five European countries.

Methods:

The analysis contrasts the contribution of the increasing severity and frequency of pain reported against respondents reporting no pain in the previous month. The data are taken from the 2008 National Health and Wellness Survey. Single-equation generalized linear regression models are used to evaluate the association of pain with the physical and mental component scores of the SF-12 questionnaire as well as health utilities generated from the SF-6D. In addition, the role of pain is assessed in its association with healthcare provider visits, emergency room visits and hospitalizations.

Results:

The results indicate that the experience of pain, notably severe and frequent pain, is substantial and is significantly associated with the SF-12 physical component scores, health utilities and all aspects of healthcare resource utilization, which far outweighs the role of demographic and socioeconomic variables, health risk factors (in particular body mass index) and the presence of comorbidities. In the case of severe daily pain, the marginal contribution of the SF-12 physical component score is a deficit of ?17.86 compared to those reporting no pain (population average score 46.49), while persons who are morbidly obese report a deficit of only ?6.63 compared to those who are normal weight. The corresponding association with health utilities is equally dramatic with a severe daily pain deficit of ?0.19 compared to those reporting no pain (average population utility 0.71).

Conclusions:

For the five largest EU countries, the societal burden of pain is considerable. The experience of pain far outweighs the contribution of more traditional explanations of HRQoL deficits as well as being the primary factor associated with increased provider visits, emergency room visits and hospitalizations.     

The impact of economic sanctions on international trade: How do threatened sanctions compare with imposed sanctions?

We draw on established theoretical works in international political economy to compare the empirical effect of threatened and imposed economic sanctions on international trade. To deepen the analysis, we analyze whether there are any differential effects when different instruments of sanctions are employed, as well as whether the effect of sanctions is product specific. To do this, we use the gravity model and recent detailed disaggregated data on sanctions spanning the period 1960–2009. Our results show that the impact of threatened sanctions differs qualitatively and quantitatively from imposed sanctions. Whereas imposed sanctions lead to a decrease in the trade flow between the sender and its target, a threat of sanctions leads to an increase. The positive impact of the threat may be due to economic agents in both the sender and its target resorting to stockpiling prior to the actual imposition of sanctions to minimize any adverse consequences of the sanctions. These differential effects of threatened and imposed sanctions also extend to food and medicinal products, as well as when different instruments of sanctions are employed.     

果胶铋联合三联疗法对消化性溃疡患者血清炎症介质及生命质量的影响

目的探讨果胶铋联合三联疗法对消化性溃疡患者血清炎症介质及生命质量的影响。方法选取2019年8月至2020年2月于大石桥市第三人民医院治疗的90例消化性溃疡患者作为研究对象,按随机数字表法分为对照组与观察组,每组45例。对照组患者予以呋喃唑酮片+奥美拉唑肠溶胶囊+阿莫西林治疗,观察组患者在对照组治疗基础上采用胶体果胶铋胶囊治疗。比较两组患者治疗后幽门螺杆菌(Hp)根除率,以及治疗前后血清一氧化氮(NO)、一氧化氮合酶(NOS)、炎症介质、消化病生命质量指数(GLQI)评分。结果治疗后,观察组Hp根除率为97.78%,明显高于对照组的77.78%,差异有统计学意义(P<0.05)。治疗前,两组患者血清NO、NOS、白细胞介素-6(IL-6)、白细胞介素-8(IL-8)水平及GLQI评分差异无统计学意义(P>0.05);治疗后,两组患者血清NO、NOS、IL-6、IL-8水平及GLQI评分较治疗前有所改善,且观察组明显优于对照组,差异有统计学意义(P<0.05)。结论果胶铋联合三联疗法可通过降低胃溃疡患者血清IL-6、IL-8水平,提高NO、NOS水平,发挥改善胃黏膜微循环、提高黏膜血容量、减轻炎症反应、抑制胃酸形成、保护胃黏膜、提高患者生命质量的作用。     

Effects of a holiday trip on health and quality of life: evidence from a natural experiment in South Korea

We examine whether having a holiday trip affects an individual’s well-being, namely quality of life, health status, stress level and health behaviours. We use the two-stage estimation method to control for endogeneity of a travel experience, exploiting a natural experiment of distributing Travel Vouchers at random among qualified applicants in South Korea in 2012. We find that, for applicants whose decision to travel is influenced by receiving a voucher, a travel experience has no significant effects on the traveller’s well-being measured 3–12 months later. We also find that the OLS estimates overstate benefits of a travel.     

盐酸普拉克索联合多巴丝肼片对帕金森病患者治疗效果、不良反应及生命质量的影响

The impact of different scenarios for intermittent bladder catheterization on health state utilities: results from an internet-based time trade-off survey

Aims: Intermittent catheterization (IC) is the gold standard for bladder management in patients with chronic urinary retention. Despite its medical benefits, IC users experience a negative impact on their quality of life (QoL). For health economics based decision making, this impact is normally measured using generic QoL measures (such as EQ-5D) that estimate a single utility score which can be used to calculate quality-adjusted life years (QALYs). But these generic measures may not be sensitive to all relevant aspects of QoL affected by intermittent catheters. This study used alternative methods to estimate the health state utilities associated with different scenarios: using a multiple-use catheter, one-time-use catheter, pre-lubricated one-time-use catheter and pre-lubricated one-time-use catheter with one less urinary tract infection (UTI) per year.

Methods: Health state utilities were elicited through an internet-based time trade-off (TTO) survey in adult volunteers representing the general population in Canada and the UK. Health states were developed to represent the catheters based on the following four attributes: steps and time needed for IC process, pain and the frequency of UTIs.

Results: The survey was completed by 956 respondents. One-time-use catheters, pre-lubricated one-time-use catheters and ready-to-use catheters were preferred to multiple-use catheters. The utility gains were associated with the following features: one time use (Canada: +0.013, UK: +0.021), ready to use (all: +0.017) and one less UTI/year (all: +0.011).

Limitations: Internet-based survey responders may have valued health states differently from the rest of the population: this might be a source of bias.

Conclusion: Steps and time needed for the IC process, pain related to IC and the frequency of UTIs have a significant impact on IC related utilities. These values could be incorporated into a cost utility analysis.     

The impact of frailty on the economic evaluation of geriatric surgery: hospital costs and opportunity costs based on meta-analysis

Abstract

Objectives: We used a systematic review and meta-analysis to analyze the difference in costs between surgery for frail and non-frail elderly patients. The opportunity cost of frailty in geriatric surgery is estimated using the results.

Methodology: Two literature reviews were carried out between 2000 and 2019: (1) studies comparing total hospital costs of frail and non-frail surgical patients; (2) studies evaluating the length of hospital stay and cost for surgical geriatric patients. We performed a meta-analysis of the items selected in the first review. We subsequently calculated the opportunity cost of frail patients, based on the design of a cost/time variable.

Results: Twelve articles in the first review were selected (272,717 non-frail and 16,461 frail). Fourteen articles were selected from the second review. Frail patients had higher hospital costs than non-frail patients (22,282.541 € and 16,388.844, p?<?.001) and a longer hospital stay (10.16 days and 8.4 (p?<?.001)). The estimated opportunity cost in frail patients is 1,019.56 € (cost/time unit factor of 579.30 €/day).

Conclusions: Frail surgical geriatric patients generate a higher total hospital cost, and an opportunity cost arising from not operating in the best possible state of health. Preoperatively treating the frailty of elderly patients will improve the use of health resources     

The economic impact of acute coronary syndrome on length of stay: an analysis using the Healthcare Cost and Utilization Project (HCUP) databases

Objective:

To assess the economic impact of initial and repeat hospitalizations associated with acute coronary syndrome (ACS) over 1 year (2009).

Design and methods:

National- and state-level data on length of stay (LOS) and related charges for ACS-associated hospital admissions were assessed using two Healthcare Utilization Project databases. The first, the Nationwide Inpatient Sample (NIS), provided clinical and resource use information from ～8 million hospital stays, representing a 20% stratified sample of ～40 million annual hospital stays in the US in 2009. The second, the State Inpatient Databases, provided 100% of inpatient data from nine states that included both patient age and linked information on multiple patient admissions within the same calendar year. For patients with repeat admissions, the LOS, primary diagnosis, and total charges between the first and subsequent admissions were evaluated. All patients ≥18 years of age with at least one diagnosis of ACS, defined using the International Classification of Diseases, 9th Revision, were included (code 410.xx [except 410.x2], 411.1x and 411.8x). Variables evaluated for each discharge included demographics, cardiovascular events and procedures, LOS, discharge status, and total charges.

Results:

The NIS reported 1,437,735 discharges for ACS in 2009. In this dataset, mean LOS for an initial ACS event was 5.56 days. Patients >65 years of age had the highest numbers of admissions; this group also had the most comorbidities. Approximately 40% of ACS patients with data on repeat visits had more than one admission, >70% of these within 2 months of the primary discharge. Mean charges were $71,336 for the first admission and $53,290 for the second admission.

Conclusion:

Despite a variety of new therapies to prevent ACS, it remains a common condition. Better therapies are called for if the clinical and cost burden of ACS is to be alleviated.
