Work impairment, osteoarthritis, and health-related quality of life among employees in Japan.

BACKGROUND: Osteoarthritis (OA) is one of the most common causes of health and work impairment; however, this relationship, especially in Japan, is not well characterized. This study examined work impairment and OA in Japanese workers, specifically the relationship with health-related quality of life (HRQoL) and health status. METHODS: This retrospective, cross-sectional observational study included the data of employed adults with a self-reported OA diagnosis from the 2014 Japan National Health and Wellness Survey. Presenteeism and absenteeism were classified using the Work Productivity and Activity Impairment (WPAI) questionnaire for impairment at work in the past week. Outcome variables included health-related quality of life, which was measured with the revised Medical Outcomes Study 36-Item Short Form Survey Instrument Health Survey (SF-36v2), and depression symptom severity, which was assessed using the Patient Health Questionnaire-9 (PHQ-9). RESULTS: The majority (71.2%) of respondents with OA reported presenteeism, and 11.1% reported absenteeism. Presenteeism and absenteeism were both associated with younger age; a lower proportion of respondents with than without presenteeism were married or living with a partner, and a greater proportion of those with absenteeism had comorbid conditions (for all, p < 0.05). Respondents with than without presenteeism reported greater use of medications to relieve OA symptoms (37.3% versus 20.9%, p < 0.05), and those with than without absenteeism reported more frequent arthritis-related problems (p = 0.032). Among those with presenteeism, depression severity was higher (5.8 ± 6.0) than for those with no presenteeism (2.9 ± 4.3; p < 0.001). Presenteeism was associated with impairments in HRQoL on all metrics for patients with OA, with lower mental (6.4 points) and physical (4.8 points) component scores on the SF-36v2 (for all, p < 0.001). CONCLUSIONS: Seven out of every 10 patients with OA experienced presenteeism, whereas one out of 10 reported absenteeism. OA respondents with presenteeism also showed greater medication use, lower HRQoL across both mental and physical components, and higher depression severity. Workplace interventions and effective treatment options are necessary strategies for improving the health of workers with OA in Japan.

Impaired Quality of Life, Work, and Activities Among Adults with Clostridium difficile Infection: A Multinational Survey.

BACKGROUND: Evidence of humanistic detriments of Clostridium difficile infection (CDI) remains limited. AIMS: To assess humanistic burden associated with CDI. METHODS: Self-reported National Health and Wellness Survey data between 2013 and 2016 were analyzed for the USA, five European countries, China, and Brazil. Outcome measures included SF-36v2® for health-related quality of life (HRQoL) and Work Productivity and Activity Impairment questionnaire. Respondents (≥ 18 years old) were classified as (1) currently treated doctor-diagnosed CDI (C-CDI), (2) doctor-diagnosed prior CDI (P-CDI), or (3) never experienced CDI (NO-CDI). Regression modeling assessed the association between CDI status and outcomes, adjusting for potential confounders. RESULTS: Of 352,780 respondents, 299, 2111, and 350,370 met the criteria for C-CDI, P-CDI, and NO-CDI, respectively, with 45% of the total from the USA. C-CDI and P-CDI respondents were older, were less often employed and had more comorbidities than those with NO-CDI. After adjustment for covariates, C-CDI and P-CDI had significantly lower HRQoL relative to NO-CDI for mental (MCS 39, 43 vs. 46) and physical (PCS 39, 41 vs. 46) component summary scores, and health utility (SF-6D 0.58, 0.64 vs. 0.71) (all p < 0.05), meeting common thresholds for minimally important differences. Those with C-CDI and P-CDI reported missing more work (21, 16 vs. 8%), greater impairment while working (43, 34 vs. 22%), and more activity impairment (61, 49 vs. 34%) than those with NO-CDI (all p < 0.05), respectively. CONCLUSIONS: CDI is associated with meaningfully worse HRQoL and greater impairment to work and activities compared with NO-CDI. The impairment directly attributable to CDI requires further evaluation.

The impact of depression among chronic low back pain patients in Japan.

BACKGROUND: Chronic low back pain (CLBP) is associated with significant disability and reductions in health related quality of life (HRQoL), which can negatively impact overall function and productivity. Depression is also associated with painful physical symptoms, and is often present in patients with chronic pain. However, the incremental burden associated with depression or symptoms of depression among CLBP patients is not well understood. The objective of this study was to investigate the impact of depression on HRQoL in CLBP and to assess the relationship between depression and work impairment and healthcare use among CLBP patients in Japan. METHODS: Data were extracted from the 2014 Japan National Health and Wellness Survey (N = 30,000). CLBP was defined by report of diagnosed low back pain ≥3 months duration. Depression was assessed using the Patient Health Questionnaire (PHQ-9). Measurements assessed included pain, HRQoL, labor force participation, work productivity and healthcare utilization. Patients with depression (PHQ-9 ≥ 10) were compared to patients without depression (PHQ-9 < 10) using t-tests for continuous and count variables and chi-square for categorical variables, which were followed by generalized linear models adjusted for covariates. The association between presenteeism and other patient outcomes and characteristics was analysed using nonparametric correlations (Spearman's rho). RESULTS: Depressed CLBP patients had significantly more severe pain and higher levels of pain compared with patients without depression (P < 0.001). Depression was associated with worse HRQoL in CLBP patients. Presenteeism, overall work impairment and activity impairment were 1.8, 1.9 and 1.7 times as high, respectively, among those with depression relative to those without depression. CLBP patients with depression had almost twice as many healthcare provider visits in 6 months than those without depression. The pattern of results remained consistent after adjustment for sociodemographic and general health characteristics. Analysis also indicated presenteeism was closely related to overall work impairment (rho = 0.99). CONCLUSIONS: Depression among CLBP patients in Japan was associated with higher pain scores and lower HRQoL scores, as well as lower labor productivity and increased healthcare use. Screening for depression in CLBP patients should be an essential part of CLBP patient care.

Effect of chronic urticaria on US patients: analysis of the National Health and Wellness Survey.

BACKGROUND: Chronic idiopathic (also called spontaneous) urticaria (CIU/CSU) is the most common form of chronic urticaria and has been associated with impairment to health outcomes, although the effect has never been assessed using a nationally representative sample in the United States. OBJECTIVES: To assess the burden of CIU/CSU from the patients' perspective in terms of health related quality of life, impairment to work and nonwork activities, and health care resource use. METHODS: Data were obtained from the US National Health and Wellness Survey. Current use of a prescription for the treatment of chronic hives was used as a proxy for CIU/CSU. Patients with CIU/CSU in the proxy group were matched 1:4 to respondents without chronic hives using survey year, sex, age, and race. Generalized linear models were adjusted for comorbidities, smoking, body mass index, and health insurance status. Outcome measures included the Medical Outcomes Study 12-Item and 36-Item Short Form Health Surveys; self-reported depression, anxiety, and sleep difficulties; the Work Productivity and Activity Impairment questionnaire, and health care resource use. RESULTS: After matching and adjustment for covariates, those currently using a prescription for chronic hives had mental component summary scores 5.7 points lower, physical component summary scores 6.5 points lower, and health utility scores 0.11 points lower than controls, as well as higher adjusted odds of reporting depression, anxiety, and sleep difficulties. Mean adjusted work impairment was approximately double in prescription-treated chronic hives relative to controls, as was frequency of health care visits. CONCLUSION: Chronic hives substantially affects quality of life, nonwork activities, capacity to work, and health care use, providing further evidence of a high burden of CIU/CSU across multiple health outcomes and unmet need for effective treatment.

The incremental burden of pain in patients with depression: results of a Japanese survey.

BACKGROUND: Major depressive disorder (MDD) is a chronic mental illness which affects an estimated 3% of the Japanese population. Many patients with MDD report painful physical symptoms, and research outside of Japan suggests such patients may represent a subtype of depression which is more severe and difficult to treat. There is no evidence available about the characteristics or incremental burden of these patients in Japan. The objective of this study was to quantify the incremental burden of physical pain among individuals in Japan diagnosed with depression. METHODS: Data for individuals age 18 and older who reported a physician diagnosis of depression were obtained from the Japan National Health and Wellness Survey (NHWS). Respondents who also reported physical pain were matched to respondents who did not report pain using propensity scores and compared using bivariate statistics. Measures included Patient Health Questionnaire (PHQ-9) for depression severity, Medical Outcomes Study 12-Item Short Form Survey Instrument (SF-12v2) for health-related quality of life, the Work Productivity and Activity Impairment (WPAI) for work and activity impairment, and 6-month report of health care use. RESULTS: Individuals with depression who reported physical pain had higher PHQ-9 depression scores (14.3 vs. 11.1, p<0.001), lower health-related quality of life (Mental Component Summary score [MCS] 29.1 vs. 32.0, p<0.01; Physical Component Summary score [PCS] 43.0 vs. 47.2, p<0.001; health utility [SF-6D] 0.567 vs. 0.613, p<0.001), more presenteeism (46.3% vs. 36.8%, p<0.01), more overall work impairment (51.4% vs. 42.3%, p<0.01), more activity impairment (55.4% vs. 43.9%, p<0.001), and reported using more health care provider visits in the prior 6 months (17.7 vs. 12.8, p<0.01) as well as hospitalizations (1.7 vs. 0.8, p<0.05) relative to propensity-score matched controls without pain. Absenteeism (13.1% vs. 11.4%, p=0.51) and emergency room visits (0.31 vs. 0.35, p=0.76) were not significantly different between the two matched groups. CONCLUSIONS: Individuals whose depression is accompanied by physical pain have a higher burden of illness than those whose depression does not include physical pain. Clinicians should take the presence of pain into account and consider treating both the physical and emotional symptoms of these patients.

Burden of benign prostatic hyperplasia among men in Japan: Patient-reported outcomes among those diagnosed and experiencing symptoms.

OBJECTIVES: To quantify the burden of benign prostatic hyperplasia among Japanese men according to patient-reported outcomes. A secondary aim was to quantify the incremental burden of nocturia among these men. METHODS: Survey data representative of the Japanese population by age and sex were analyzed (total n = 59 997). All measures were self-reported, including the revised Medical Outcomes Study 12-Item Short Form Health Survey or the revised Medical Outcomes Study 36-Item Short Form Health Survey, Work Productivity and Activity Impairment questionnaire, and 6-month healthcare use. Men aged ≥50 years were organized into three analysis groups according to diagnosis of benign prostatic hyperplasia and International Prostate Symptom Score total: diagnosed benign prostatic hyperplasia (n = 1183); undiagnosed benign prostatic hyperplasia with moderate to severe symptoms (International Prostate Symptom Score total ≥8; n = 3141); and controls (no benign prostatic hyperplasia diagnosis and International Prostate Symptom Score total <8; n = 9468). Subgroup analyses were carried out according to frequency of nocturia. Generalized linear models adjusted for potential confounders. RESULTS: Relative to controls, diagnosed and undiagnosed benign prostatic hyperplasia respondents had reduced health-related quality of life, with mean decrements of ≥3.1 points for mental component summary scores, ≥2.0 for physical component summary scores and ≥0.05 for health utility scores (all P < 0.001). Mean absenteeism, impairment at work and non-work activity impairment among the diagnosed and undiagnosed groups were ≥1.4-fold those of the control group (P < 0.01). Both diagnosed and undiagnosed groups used significantly more healthcare than controls. The outcomes of undiagnosed men were worse than diagnosed patients on many measures. Frequent nocturia (≥3 voids per night) was associated with worse health-related quality of life. CONCLUSIONS: Benign prostatic hyperplasia impacts health-related quality of life, work productivity and healthcare use of Japanese men, with more impact among undiagnosed men experiencing lower urinary tract symptoms and frequent nocturia.

Prescription opioid abuse and tampering in the United States: results of a self-report survey.

OBJECTIVE: The objective of this study is to estimate the prevalence and impact of prescription opioid abuse and tampering among US adults. METHODS: Participants from the US National Health and Wellness Survey were invited to complete an online survey assessing use, misuse, and abuse of prescription opioid medications in the preceding 3 months. A total of 25,864 adults were screened for self-reported opioid abuse. Prevalence was calculated using weights based on age, gender, race, and education. Respondents reporting abuse or medical use of prescription opioid medication in the prior 3 months (N = 1,242) completed a questionnaire assessing health care resource use and the Work Productivity and Activity Impairment questionnaire. RESULTS: The prevalence of prescription opioid abuse in the 3 months prior to the survey was estimated at 1.31% of US adults, with approximately half (0.67%) tampering during that time. Opioid abuse increased with younger age, male sex, minority race, psychiatric illness, alcoholism, cigarette smoking, being employed, and higher household income. Respondents abusing opioid medications reported greater impairment in work and nonwork activities and more health care use than nonusers. Tampering with opioid medication was associated with greater productivity loss and increased use of health care (all P < 0.05). CONCLUSIONS: Tampering with opioid medications to get high is associated with substantial loss of productivity and health care use. Technologies that reduce users' ability to tamper may reduce the burden of opioid abuse on the health care system.

Health-related quality of life in patients with hepatitis C virus infection in Brazil.

OBJECTIVE: To quantify the health-related quality of life (HRQoL) burden of hepatitis C virus (HCV) infection among a broad sample of adults in Brazil, particularly among those 40 years of age and older. METHODS: This was a retrospective observational study of data from the 2011 Brazil National Health and Wellness Survey, a large (n = 12 000) cross-sectional survey that includes information on medical conditions and health outcomes, including the Medical Outcomes Study Short-form 12 health questionnaire, version 2 (SF-12v2). Respondents who reported a physician diagnosis of HCV infection were compared with those who reported never experiencing HCV on the Mental (MCS) and Physical (PCS) Component Summary scores and SF-6D health utility scores. Unadjusted comparisons were conducted with chi-square tests for categorical variables and t-tests for continuous variables. Regression was used to adjust outcomes for potential confounds. Subgroup analyses were conducted on those 40 years of age and older. RESULTS: Unadjusted comparisons between respondents infected with HCV (n = 100) and controls (n = 11 694) revealed similar MCS and PCS scores, but HCV patients had lower SF-6D utility scores (0.70 vs. 0.73, P < 0.05). Regressions adjusting for demographic and health characteristics provided similar results to unadjusted comparisons. Subgroup analyses of respondents 40 years of age and older revealed decrements in both MCS (45.95 vs. 49.72, P < 0.05) and SF-6D (0.71 vs. 0.76, P < 0.05). PCS scores were comparable in HCV patients and controls. CONCLUSIONS: HCV infection in Brazil causes significant HRQoL burden, especially among the older population. Prevention measures to curtail the spread of the virus in Brazil should provide societal benefits in terms of quality of life, in addition to preventing morbidity and mortality from chronic infection.

Estimating the Population Newly Eligible for the Pneumococcal Conjugate Vaccine.

INTRODUCTION: Recommendations for adult pneumococcal vaccination in the U.S. were revised in 2022 after the introduction of 15- and 20-valent pneumococcal conjugate vaccines (PCV15 and PCV20) to call for routine PCV use among immunocompetent adults with risk conditions aged 19-64 years. The present study estimated the size of this newly recommended population. METHODS: A retrospective cohort study was conducted using the Optum de-identified electronic health record (EHR) dataset. Patients who were active in the EHR between January 2016 and June 2021 and had ≥1 condition included in the current pneumococcal recommendation without an immunocompromising condition were included. Data were weighted to account for potential differences between the EHR and U.S. POPULATION: Data analyses were conducted in 2022. RESULTS: Of 45.6 million adults aged 19-64 years in the database, 12.5 million met inclusion criteria and had ≥1 qualifying condition, primarily smoking, with chronic lung disease/asthma and/or diabetes also common. After weighting, the U.S. population aged 19-64 years newly eligible for PCVs was approximately 56 million. CONCLUSIONS: Approximately one in four U.S. adults aged <65 years is now recommended to receive PCV15 or PCV20, which highlights the need for providers to assess vaccination status, administer the vaccine, or refer patients as appropriate, as well as the need for tools to facilitate patient identification and vaccination.

Best Practices for Identifying Hospitalized Lower Respiratory Tract Infections Using Administrative Data: A Systematic Literature Review of Validation Studies.

INTRODUCTION: Estimating the burden of lower respiratory tract infections (LRTIs) increasingly relies on administrative databases using International Classification of Diseases (ICD) codes, but no standard methodology exists. We defined best practices for ICD-based algorithms that estimate LRTI incidence in adults. METHODS: We conducted a systematic review of validation studies assessing the use of ICD code-based algorithms to identify hospitalized LRTIs in adults, published in Medline, EMBASE, and LILACS between January 1996 and January 2022, according to PRISMA guidelines. We assessed sensitivity, specificity, and other accuracy measures of different algorithms. RESULTS: We included 26 publications that used a variety of ICD code-based algorithms and gold standard criteria, and 18 reported sensitivity and/or specificity. Sensitivity was below 80% in 72% (38/53) of algorithms and specificity exceeded 90% in 77% (37/48). Algorithms for all-cause LRTI (n = 18) that included only pneumonia codes in primary position (n = 3) had specificity greater than 90% but low sensitivity (55-72%). Sensitivity increased by 5-15%, with minimal loss in specificity, with the addition of primary codes for severe pneumonia (e.g. sepsis) while pneumonia codes were in secondary position, and by 13% with codes from LRTI-related infections (e.g. viral) or other respiratory diseases (e.g. empyema). Sensitivity increased by 8% when pneumonia codes were in any position, but specificity was not reported. In hospital-acquired pneumonia and pneumococcal-specific pneumonia, algorithms containing only nosocomial- or pathogen-specific ICD codes had poor sensitivity, which improved when broader pneumonia codes were added, in particular codes for unspecified organisms. CONCLUSION: Our systematic review highlights that most ICD code-based algorithms are relatively specific, but miss a substantial number of hospitalized LRTI adult cases. Best practices to estimate LRTI incidence in this population include the use of all pneumonia ICD codes for any LRTI outcome and, to a lesser extent, those for other LRTI-related infections or respiratory diseases.

Cost-effectiveness analysis of adult pneumococcal conjugate vaccines for pneumococcal disease in Japan.

BACKGROUND: The 23-valent pneumococcal polysaccharide vaccine (PPSV23) is used in the Japanese National Immunization Program for older adults and adults with increased risk for pneumococcal disease, however, disease incidence and associated burden remain high. We evaluated the cost-effectiveness of pneumococcal conjugate vaccines (PCVs) for adults aged 65 years and high-risk adults aged 60-64 years in Japan. RESEARCH DESIGN AND METHODS: Using a Markov model, we evaluated lifetime costs using societal and healthcare payer perspectives and estimated quality-adjusted life-years (QALYs), and number of prevented cases and deaths caused by invasive pneumococcal disease (IPD) and non-IPD. The base case analysis used a societal perspective. RESULTS: In comparison with PPSV23, the 20-valent PCV (PCV20) prevented 127 IPD cases 10,813 non-IPD cases (inpatients: 2,461, outpatients: 8,352) and 226 deaths, and gained more QALYs (+0.0015 per person) with less cost (-JPY22,513 per person). All sensitivity and scenario analyses including a payer perspective analysis indicated that the incremental cost-effectiveness ratios (ICERs) were below the cost-effectiveness threshold value in Japan (JPY5 million/QALY). CONCLUSIONS: PCV20 is both cost saving and more effective than PPSV23 for adults aged 65 years and high-risk adults aged 60-64 years in Japan.

A latent class analysis of factors influencing preferences for infant respiratory syncytial virus (RSV) preventives among pregnant people in the United States.

A maternal vaccine and long-acting monoclonal antibody (mAb) were recently approved to protect infants against respiratory syncytial virus (RSV). We identified subgroups of pregnant people with different preferences for RSV preventives and respondent characteristics associated with subgroup membership. An online survey, including a discrete choice experiment (DCE), was conducted among US pregnant people. RSV preventive attributes included effectiveness, duration of protection during RSV season, injection recipient/timing, preventive type (vaccine or mAb), and type of visit required to receive injection. In DCE choice tasks, pregnant people selected between two hypothetical preventive profiles with varying attribute-levels and a no-preventive option. Logistic regression, including latent class analysis (LCA), was used to analyze the data. Of 992 pregnant people (mean age: 30.0 years), 60.3% were expecting their second/later birth. LCA identified three preference subgroups: 'Effectiveness' (preventive choice mostly driven by increases in effectiveness; 51.4% class membership probability), 'Season' (preventive choice mostly driven by improvement in duration of protection during the RSV season; 39.2% class membership probability), and 'No Preventive' (frequently chose no-preventive option; 9.4% class membership probability). 'Effectiveness' and 'Season' preferred maternal vaccine over mAb; mAb was preferred by 'No Preventive.' Perceiving RSV as serious for infants, higher health literacy, and lower household income were associated with 'Effectiveness.' Perceiving RSV as serious for pregnant people was associated with 'Season.' Perceiving RSV to not be serious for pregnant people and not being employed were associated with 'No Preventive.' Subgroups of pregnant people vary in preferences for RSV preventives. Most pregnant people preferred a maternal vaccine, although some may be more willing to accept alternative preventive options.

Healthcare Providers' and Pregnant People's Preferences for a Preventive to Protect Infants from Serious Illness Due to Respiratory Syncytial Virus.

We assessed the impact of respiratory syncytial virus (RSV) preventive characteristics on the intentions of pregnant people and healthcare providers (HCPs) to protect infants with a maternal vaccine or monoclonal antibodies (mAbs). Pregnant people and HCPs who treated pregnant people and/or infants were recruited via convenience sample from a general research panel to complete a cross-sectional, web-based survey, including a discrete choice experiment (DCE) wherein respondents chose between hypothetical RSV preventive profiles varying on five attributes (effectiveness, preventive type [maternal vaccine vs. mAb], injection recipient/timing, type of medical visit required to receive the injection, and duration of protection during RSV season) and a no-preventive option. A best-worst scaling (BWS) exercise was included to explore the impact of additional attributes on preventive preferences. Data were collected between October and November 2022. Attribute-level preference weights and relative importance (RI) were estimated. Overall, 992 pregnant people and 310 HCPs participated. A preventive (vs. none) was chosen 89.2% (pregnant people) and 96.0% (HCPs) of the time (DCE). Effectiveness was most important to preventive choice for pregnant people (RI = 48.0%) and HCPs (RI = 41.7%); all else equal, pregnant people (RI = 5.5%) and HCPs (RI = 7.2%) preferred the maternal vaccine over mAbs, although preventive type had limited influence on choice. Longer protection, protection starting at birth or the beginning of RSV season, and use for both pre-term and full-term babies were ranked highest in importance (BWS). Pregnant people and HCPs strongly preferred a preventive to protect infants against RSV (vs. none), underscoring the need to incorporate RSV preventives into routine care.

The burden of hepatitis C in Europe from the patients' perspective: a survey in 5 countries.

BACKGROUND: Few studies have examined the impact of Hepatitis C virus (HCV) infection on patient reported outcomes in Europe. This study was conducted to assess the burden of HCV infection in terms of work productivity loss, activity impairment, health-related quality of life, healthcare resource utilization, and associated costs. METHODS: The 2010 European National Health and Wellness Survey (n = 57,805) provided data. Patients reporting HCV infection in France, Germany, the UK, Italy, and Spain were matched to respondents without HCV using propensity scores. Outcome measures included the Work Productivity and Activity Impairment (WPAI) questionnaire and the Medical Outcomes Study Short Form-12 (SF-12v2) questionnaire. Subgroup analyses focused on treatment-naïve patients. RESULTS: HCV Patients (n = 286) had more work impairment (30% vs. 18%, p < .001), more impairment in non-work activities (34% vs. 28%, p < .05), and more annual physician visits per patient (19.8 vs. 13.3, p < .001). Estimated indirect and direct costs were €2,956 (p < .01) and €495 (p < .001) higher than in matched controls, respectively. Health-related quality of life was also lower among HCV patients. Treatment-naïve HCV patients (n = 139) also reported higher work impairment (29% vs. 15%, p < .01), as well as more frequent physician visits (19.5 vs. 12.1, p < .01) than matched controls. Each treatment-naïve HCV infected patient incurred €934 in direct costs vs. €508 (p < .01 in matched controls. Employed treatment-naïve patients reported higher productivity loss per year compared to matched controls (€6,414 vs. €3,642, p < .05). CONCLUSION: HCV infection in Europe is associated with considerable economic and humanistic burden. This is also true of diagnosed patients who have never been treated for HCV.

Hypoglycaemic events in patients with type 2 diabetes in the United Kingdom: associations with patient-reported outcomes and self-reported HbA1c.

BACKGROUND: One possible barrier to effective diabetes self-management is hypoglycaemia associated with diabetes medication. The current study was conducted to characterize hypoglycaemic events among UK patients with type 2 diabetes (T2D) treated with antihyperglycaemic medications, and assess the relationship between experience of hypoglycaemic events and health outcomes, including glycaemic control, health-related quality of life, impairment to work and non-work activities, treatment satisfaction, adherence to treatment, fear of hypoglycaemia, and healthcare resource use. METHODS: An online survey of 1,329 T2D patients in UK drawn from an opt-in survey panel was conducted in February of 2012 with monthly follow-up questionnaires for five months. Measures included self-reported HbA1c, EQ-5D, Work Productivity and Activity Impairment questionnaire, Diabetes Medication Satisfaction Tool, Morisky medication adherence scale, the Hypoglycaemia Fear Survey (revised), and self-reported healthcare resource use. Comparisons were conducted using t-tests and chi-square tests for continuous and categorical variables, respectively. RESULTS: Baseline comparisons showed that worse HbA1c, greater diabetes-related healthcare resource use, greater fear of hypoglycaemia, and impaired health outcomes were associated with experience of hypoglycaemia in the four weeks prior to baseline. Longitudinal results were similar in direction but differences on few measures were significant. CONCLUSIONS: In real-world UK T2D patients, hypoglycaemia is associated with worse self-reported glycaemic control, behaviours that contribute to worse glycaemic control, and impairment in patient-reported outcomes.

Cost-utility of 20-valent pneumococcal conjugate vaccine compared to no vaccination and recommended alternative vaccines among Belgian adults.

BACKGROUND: The Belgian Superior Health Council (SHC) preferentially recommended the 20-valent pneumococcal conjugate vaccine (PCV20) for adults aged ≥65 years, immunocompromised patients, and patients aged ≥50 years suffering from conditions that increase their risk for pneumococcal infections. The objective of this paper is to present the cost-utility of PCV20 compared to no vaccination and the alternative sequence of PCV15 followed by the 23-valent pneumococcal polysaccharide vaccine (PPV23) in this population. RESEARCH DESIGN AND METHODS: The analysis employed a static Markov model capturing lifetime risk of pneumococcal infections, associated disutility, mortality, and costs from different healthcare payer perspectives. RESULTS: Results indicated use of PCV20 among Belgian older and at-risk adults is highly cost-effective compared to no vaccination, with an incremental cost per quality-adjusted life-year (QALY) of €4,164. Compared to the sequential regimen (PCV15+PPV23), PCV20 vaccination is a cost-saving strategy. Subgroup analysis indicated PCV20 vaccination of at-risk adults aged 65-84 years would also be cost-saving from the national healthcare perspective. CONCLUSION: Based on current knowledge, this analysis suggests that access to PCV20 should be proposed in all adults recommended for vaccination by the SHC as PCV20 prevents additional hospitalizations and deaths caused by pneumococcal infection at an affordable cost.

Pneumococcal infections cause a high burden on infected patients and society. Vaccination of patients at risk of severe infection has been recommended for decades, but uptake of pneumococcal vaccines in adults has historically been low in Belgium, where patients have borne the vaccine costs and the recommended vaccination schedule required the sequential administration of two vaccines. A single PCV20 dose is recommended as the preferred vaccine for adults at risk due to age or other factors in Belgium as it is expected to provide lasting protection against more types of disease-causing pneumococcal bacteria as well as being simpler to administer than alternatives requiring multiple injections. Uptake is expected to improve with the recent reimbursement of the new PCV20 vaccine, though reimbursement covers only a portion of the recommended population. This paper presents a detailed analysis of the PCV20 cost-effectiveness in all adults at increased risk of severe pneumococcal disease, including immunocompromised adults younger than 65 years. Our analysis captures and compares the lifetime risk of pneumococcal disease and associated healthcare costs in an unvaccinated cohort, a cohort vaccinated with the alternative recommendation of PCV15 and PPV23 vaccines and a cohort vaccinated with PCV20. This cost-effectiveness analysis indicates that use of PCV20 will help decrease the number of pneumococcal disease cases, hospitalizations, and premature deaths at an affordable healthcare cost: PCV20 is a cost-effective option compared to no vaccination and a cost-saving option compared to the sequential regimen PCV15 followed by PPV23 in the Belgian adult population recommended for pneumococcal vaccination.

Health and economic outcomes of 20-valent pneumococcal conjugate vaccine compared to 15-valent pneumococcal conjugate vaccine strategies for adults in Greece.

Objective: Higher valency pneumococcal conjugate vaccines (PCVs) are expected to improve protection against pneumococcal disease through coverage of additional serotypes. The aim of the present study was to evaluate the cost-effectiveness of 20-valent pneumococcal conjugate vaccine (PCV20) compared to 15-valent pneumococcal conjugate vaccine (PCV15) alone or followed by 23-valent polysaccharide vaccine (PPV23) for adults in Greece. Methods: A published Markov model was adapted to simulate lifetime risk of clinical and economic outcomes from the public payer's perspective. The model population was stratified based on age and risk profile (i.e., low, moderate, or high-risk of developing pneumococcal disease). Epidemiologic parameters, serotype coverage and vaccines' effectiveness were based on published literature, while direct medical costs (prices €, 2022) were obtained from official sources. Main model outcomes were projected number of invasive pneumococcal disease (IPD) and all-cause non-bacteremic pneumonia (NBP) cases and attributable deaths, costs and quality-adjusted life-years (QALY) for each vaccination strategy. Sensitivity analyses were performed to ascertain the robustness of model results. Results: Over the modeled time horizon, vaccination with PCV20 compared to PCV15 alone or PCV15 followed by PPV23 prevents an additional 747 and 646 cases of IPD, 10,334 and 10,342 cases of NBP and 468 and 455 deaths respectively, resulting in incremental gain of 1,594 and 1,536 QALYs and cost savings of €11,183 and €48,858, respectively. PSA revealed that the probability of PCV20 being cost-effective at the predetermined threshold of €34,000 per QALY gained was 100% compared to either PCV15 alone or the combination of PCV15 followed by PPV23. Conclusion: PCV20 is estimated to improve public health by averting additional pneumococcal disease cases and deaths relative to PCV15 alone or followed by PPV23, and therefore translates to cost-savings for the public payer. Overall results showed that vaccination with PCV20 was estimated to be a dominant vaccination strategy (improved health outcomes with reduced costs) over PCV15 alone or followed by PPV23 for prevention of pneumococcal disease in adults in Greece.

Pneumococcal vaccine uptake among Medicare Beneficiaries aged ≥65 years following the shared clinical decision-making recommendation for 13-valent pneumococcal conjugate vaccine in 2019.

BACKGROUND: In November 2019, the US Advisory Committee on Immunization Practices recommended shared clinical decision-making (SCDM) for use of 13-valent pneumococcal conjugate vaccine (PCV13) among immunocompetent elderly adults. The impact of SCDM on PCV13 use in this population, immunocompromised persons, and vulnerable subgroups has not been well documented. METHODS: Using Medicare Research Identifiable Files (01/2018 - 09/2020), monthly uptake of pneumococcal vaccine (PCV13, 23-valent pneumococcal polysaccharide vaccine [PPSV23]) was identified among fee-for-service beneficiaries aged ≥ 65 years with Part B coverage and no evidence of prior PCV13. Uptake was stratified by vaccine, risk profile, and demographics. RESULTS: Among the > 12 M beneficiaries included each month, PCV13 uptake declined from > 70% of pneumococcal vaccinations before SCDM to < 60% after SCDM (02/2020). Reductions in PCV13 uptake were consistent across vulnerable subgroups as well as immunocompromised persons. CONCLUSIONS: PCV13 use decreased among immunocompetent and immunocompromised persons alike, despite continued routine PCV13 recommendation for the latter group.

Incidence and clinical outcomes of pneumonia in persons with down syndrome in the United States.

BACKGROUND: Persons with Down syndrome (DS) experience an increased risk of pneumonia. We determined the incidence and outcomes of pneumonia and relationship to underlying comorbidities in persons with and without DS in the United States. METHODS: This retrospective matched cohort study used de-identified administrative claims data from Optum. Persons with DS were matched 1:4 to persons without DS on age, sex, and race/ethnicity. Pneumonia episodes were analyzed for incidence, rate ratios and 95 % confidence intervals, clinical outcomes, and comorbidities. RESULTS: During 1-year follow-up among 33796 persons with and 135184 without DS, the incidence of all-cause pneumonia (pneumonia) was substantially higher among people with DS than those without DS (12427 vs. 2531 episodes/100000 person-years; 4.7-5.7 fold increase). Persons with DS and pneumonia were more likely to be hospitalized (39.4 % vs. 13.9 %) or admitted to the ICU (16.8 % vs. 4.8 %). Mortality was higher 1 year after first pneumonia (5.7 % vs. 2.4 %; P < 0.0001). Results were similar for episodes of pneumococcal pneumonia. Specific comorbidities were associated with pneumonia, particularly heart disease in children and neurologic disease in adults, which only partially mediated the effect of DS on pneumonia. CONCLUSIONS: Among persons with DS, incidence of pneumonia and associated hospitalizations were increased; mortality among those with pneumonia was comparable at 30 days, but higher at 1 year. DS should be considered an independent risk condition for pneumonia.

Cost-effectiveness of use of 20-valent pneumococcal conjugate vaccine among adults in Germany.

OBJECTIVES: Despite national recommendations for use of pneumococcal vaccines, rates of community-acquired pneumonia (CAP) and invasive pneumococcal disease (IPD) remain high in Germany. New pneumococcal conjugate vaccines (PCVs) with expanded coverage have the potential to reduce the pneumococcal disease burden among adults. METHODS: Using a Markov model, we evaluated the lifetime outcomes/costs comparing 20-valent PCV (PCV20) with standard of care (SC) vaccinations for prevention of CAP and IPD among adults aged ≥60 years and at-risk adults aged 18-59 years in Germany. PCV20 also was compared with sequential vaccination with 15-valent PCV (PCV15) followed by PPSV23 in a scenario analysis. RESULTS: Over the course of a lifetime (82 years), use of PCV20vs. SC would prevent 54,333 hospitalizations, 26368 outpatient CAP cases, 10946 disease-related deaths yield 74,694 additional life-years (LYs), while lowering total medical costs by 363.2 M €. PCV20 remained cost saving (i.e. dominant) versus SC even in numerous sensitivity analyses, including a sensitivity analysis assuming moderate effectiveness of the SC pneumococcal polysaccharide vaccine against noninvasive pneumococcal CAP. In several scenario analyses and a probabilistic sensitivity analysis, PCV20 was also cost-saving compared toPCV15 PPSV23 vaccination. CONCLUSIONS: One dose of PCV20 among adults aged ≥60 years and adults aged 18-59 years with moderate- and high-risk conditions wouldsubstantially reduce pneumococcal disease, save lives, and be cost saving compared with SC.
