Prevalence and Factors Associated With Patient-Clinician Discordance Among Patients With Rheumatoid Arthritis Initiating Advanced Therapy.

OBJECTIVE: To describe and identify associated factors for patient-clinician discordance of disease assessment at biologic or Janus kinase inhibitor (JAKi) initiation and over 12 months following initiation in patients with rheumatoid arthritis (RA) from a US RA registry. METHODS: Analyses included CorEvitas RA Registry patients who initiated their first biologic or JAKi on or after February 1, 2015, and had 6- and 12-month follow-up visits. Positive discordance was defined as patient global assessment (visual analog scale [VAS-100]) minus physician's global assessment (VAS-100) equal to 30 points or more. Persistent discordance was defined as positive discordance at all three visits. Mixed-effects logistic regression was used to determine risk factors for positive discordance at initiation and for persistent discordance. RESULTS: Among 2227 first-time biologic/JAKi-initiating patients, 613 had both follow-up visits available and were included in initiation visit analyses, and of these, 163 had positive discordance at initiation and were included in persistent discordance analyses. About 30% of all patients had positive discordance at any visit, and one third of these (10% total) were persistent at all three visits. Multivariable analyses revealed that worse scores on the Clinical Disease Activity Index, greater patient-reported pain and fatigue, and greater functional impairment were associated with positive discordance at the time of therapy initiation. Being disabled versus working full-time and being female were associated with higher odds and having Medicare versus no insurance was associated with lower odds of having persistent positive discordance. CONCLUSION: Results suggest positive discordance is common among real-world patients with RA initiating their first biologic or JAKi. The identified risk factors associated with patient-clinician discordance will help clinicians foster a more patient-centric discussion in treatment decisions.

Economic impact of applying the AASLD-IDSA simplified treatment algorithm on the real-world management of hepatitis C.

BACKGROUND: The American Association for the Study of Liver Diseases (AASLD) and the Infectious Diseases Society of America (IDSA) recommended in May 2019 that patients with hepatitis C virus (HCV) could be assessed for treatment initiation with a simplified treatment algorithm. This approach uses standard blood and fibrosis tests, rather than genotype testing, to guide the initiation of pan-genotypic direct-acting antiviral agents (DAAs) sofosbuvir/velpatasvir (SOF/VEL) or glecaprevir/pibrentasvir (GLE/PIB) treatment. OBJECTIVE: To compare health care resource utilization (HCRU) and costs for patients who initiated treatment via the simplified vs nonsimplified algorithm (genotype testing). METHODS: We identified adults with commercial and Medicare Advantage coverage who were diagnosed with HCV who initiated SOF/VEL or GLE/PIB from July 1, 2016, through August 31, 2019, in a nationally representative US administrative claims database. The index date was defined as the first pharmacy SOF/VEL or GLE/PIB fill date. Continuous enrollment 12 months before and ≥6 months after index date was required. Patients with claims for hepatitis B, HIV, decompensated liver, or prior DAAs were excluded. Patients were propensity score-matched (1:1) and grouped as "simplified" or "nonsimplified." HCV-related HCRU and costs were compared for the post-matched groups. RESULTS: 3,539 HCV patients were included, and 16.6% initiated SOF/VEL or GLE/PIB via the simplified algorithm. Pre-matched treatments were SOF/VEL (52.8%) and GLE/PIB (47.2%). More than half (55.7%) of SOF/VEL and 44.3% of GLE/PIB patients started treatment via the simplified algorithm. HCV patients initiating via the simplified algorithm were more likely to be male (65.1% vs 60.6%; P = 0.041), commercially insured (53.3% vs 46.5%; P = 0.003), and in the Midwest (25.7% vs 19.3%; P < 0.001) vs nonsimplified patients. The nonsimplified group had more liver disease (52.1% vs 46.9%; P = 0.019), metabolic disorders (45.8% vs 39.2%; P = 0.003), and dyslipidemia (39.9% vs 35.4%; P = 0.041) vs the simplified group. Of the index prescriptions, 58.9% were written by gastroenterology or infectious disease specialists, and 68.1% (simplified) vs 75.4% (nonsimplified) had a specialist visit within 90 days prior to index DAA fill (P < 0.001). Matching resulted in 584 well-matched patients in each group. At post-match baseline, the simplified treatment group had significantly lower median (interquartile range [IQR]) HCV-related medical health care costs vs the matched nonsimplified group: $373 ($201-$684) vs $727 ($456-$1,185; P < 0.001). Median noninpatient/emergency department health plan-paid costs were also significantly lower in the simplified cohort ($257 vs $504; P < 0.001). During follow-up, medical HCV-related health care costs were similar across the groups. CONCLUSIONS: This study compared economic outcomes of HCV treatment initiation via the simplified and nonsimplified algorithms. The simplified approach resulted in lower use of health care resources, greater cost savings, and greater ability of patients to access care from both specialist and nonspecialist providers. While additional studies are needed, these early findings suggest a feasible path for simplified HCV treatment in real-world managed care settings.

Characteristics and Healthcare Costs in the Aging Hepatitis B Population of Japan: A Nationwide Real-World Analysis.

INTRODUCTION: Advancing age, comorbidity, and financial burden have been observed in chronic hepatitis B (CHB) patients globally. As Japan is leading the world in aging demographics, similar real-world data are urgently needed for its CHB population to inform all stakeholders. METHODS: This cross-sectional study characterized the demographics, comorbidities, and healthcare costs of a large Japanese real-world adult (≥18 years) CHB patient (ICD-10: B18.1) population from the Medical Data Vision database from January 01, 2012, to December 31, 2016. Comorbidities were identified by ICD-10 codes, and the annual point prevalence and Charlson Comorbidity Index (CCI) score were calculated. Annual mean and median all-cause healthcare utilization and costs per patient were calculated. Comparison tests were conducted for CCI scores, prevalence of comorbidities, and healthcare resource utilization and costs. RESULTS: We identified 11,125 CHB patients. Between 2012 and 2016, the mean age increased from 62.0 to 65.2 years, and the percentage of those aged ≥65 years increased from 45.6% to 60.7%. The prevalence of cirrhosis remained similar (5.8% in 2012 and 5.6% in 2016, p = 0.69) while hepatocellular carcinoma decreased from 6.3% to 4.5% (p < 0.01). The prevalence of nonliver comorbidities increased (40.9-52.0% for cancer [p < 0.01], 12.1-17.7% for osteoporosis [p < 0.01], and 10.7-15.0% for renal impairment [p < 0.01]). Healthcare resource utilization and costs also increased, with a 119.3% increase in median total healthcare costs from JPY 229,143 in 2012 to 502,467 in 2016 (p < 0.01). CONCLUSIONS: The CHB population of Japan is predominantly elderly and carry a high nonliver comorbidity burden, while incurring increasing healthcare costs.

Remdesivir Versus Standard-of-Care for Severe Coronavirus Disease 2019 Infection: An Analysis of 28-Day Mortality.

BACKGROUND: Remdesivir is approved by the US Food and Drug Administration for the treatment of patients hospitalized with coronavirus disease 2019 (COVID-19) and has been shown to shorten time to recovery and improve clinical outcomes in randomized trials. METHODS: This was the final day 28 comparative analysis of data from a phase 3, randomized, open-label study comparing 2 remdesivir regimens (5 vs 10 days, combined for this analysis [remdesivir cohort]) and a real-world retrospective longitudinal cohort study of patients receiving standard-of-care treatment (nonremdesivir cohort). Eligible patients, aged ≥18 years, had confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), oxygen saturation ≤94% on room air or required supplemental oxygen, with pulmonary infiltrates. Propensity score matching (up to 1:10 ratio) was used to ensure comparable populations. We assessed day 14 clinical recovery (determined using a 7-point ordinal scale) and day 28 all-cause mortality (coprimary endpoints). RESULTS: A total of 368 (remdesivir) and 1399 (nonremdesivir) patients were included in the matched analysis. The day 14 clinical recovery rate was significantly higher among the remdesivir versus the nonremdesivir cohort (65.2% vs 57.1%; odds ratio [OR], 1.49; 95% confidence interval [CI], 1.16-1.90; P = 0.002). The day 28 mortality rate was significantly lower in the remdesivir cohort versus the nonremdesivir cohort (12.0% vs 16.2%; OR, 0.67; 95% CI, 0.47-.95; P = .03). CONCLUSIONS: Remdesivir was associated with significantly higher rates of day 14 clinical recovery, and lower day 28 mortality, compared with standard-of-care treatment in hospitalized patients with COVID-19. These data, taken together, support the use of remdesivir to improve clinical recovery and decrease mortality from SARS-CoV-2 infection.

Shifting demographics and comorbidity burden in adult Chinese urban patients with chronic hepatitis B, 2013 and 2016.

Chronic hepatitis B demographics and comorbidity data are limited in China. Materials & methods: The China Health Insurance Association claims database from 2013 and 2016 was used to augment the existing data: the proportion of patients aged >45 years increased significantly from 40.3% in 2013 to 49% in 2016 (p < 0.001). Results: Significant increases in multiple comorbidities were observed, including hypertension (9.4-14.5%), hyperlipidemia (4.7-7.0%) and cardiovascular disease (5.7-10%; p < 0.001 for all comparisons). Increases were observed in renal impairment (8.8-10.0%; p < 0.001) and osteoporosis and/or pathologic nontraumatic bone fracture (3.8-7.3%; p < 0.001). Conclusion: Careful selection of treatment options and comorbidity monitoring should be considered when managing adult Chinese patients with chronic hepatitis B.

Comorbidities and healthcare costs and resource use of patients with nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) in the Japan medical data vision database.

BACKGROUND: This study examined demographics, comorbidities and healthcare resource use (HCRU) and costs among Japanese patients with nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH). METHODS: We conducted a repeated cross-sectional analysis of the Medical Data Vision (MDV) claims database, from January 2011 to March 2018. Demographics were described at index date and by calendar year; a "NASH" subpopulation included patients with ≥ 1 claim for NASH at any time. Prevalence of pre-specified comorbidities of interest and data-emergent top comorbidities were estimated. All-cause HCRU and costs were quantified by calendar year. Outcomes were compared between 2011 and 2017 using partially overlapping t tests. RESULTS: 58,958 patients (mean age 61.6 years; 55.5% male) were included. 1139 patients (2%) were in the NASH subpopulation. At baseline, comorbid cardiovascular disease (69.4%), diabetes (62.1%) and hyperlipidaemia (54.4%) were most prevalent; comorbidity prevalence increased with age. Mean outpatient visits decreased from 9.36 per patient in 2011 to 7.80 in 2017; mean inpatient admissions increased (both p < 0.001 for 2011 vs 2017). Mean total all-cause healthcare costs ranged from ¥322,206 to ¥340,399 per patient per year between 2011 and 2017. Although total all-cause healthcare costs did not change significantly (p = 0.552), cost burden shifted from the outpatient to inpatient setting between 2011 and 2017. All-cause healthcare resource use/costs were generally higher for the NASH subgroup compared with the overall population. CONCLUSIONS: There is a high burden of disease among Japanese NAFLD/NASH patients, including a high prevalence of comorbidities which generally increase with age. Accordingly, substantial all-cause HCRU and costs were incurred.

Remdesivir for Severe Coronavirus Disease 2019 (COVID-19) Versus a Cohort Receiving Standard of Care.

BACKGROUND: We compared the efficacy of the antiviral agent, remdesivir, versus standard-of-care treatment in adults with severe coronavirus disease 2019 (COVID-19) using data from a phase 3 remdesivir trial and a retrospective cohort of patients with severe COVID-19 treated with standard of care. METHODS: GS-US-540-5773 is an ongoing phase 3, randomized, open-label trial comparing two courses of remdesivir (remdesivir-cohort). GS-US-540-5807 is an ongoing real-world, retrospective cohort study of clinical outcomes in patients receiving standard-of-care treatment (non-remdesivir-cohort). Inclusion criteria were similar between studies: patients had confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, were hospitalized, had oxygen saturation ≤94% on room air or required supplemental oxygen, and had pulmonary infiltrates. Stabilized inverse probability of treatment weighted multivariable logistic regression was used to estimate the treatment effect of remdesivir versus standard of care. The primary endpoint was the proportion of patients with recovery on day 14, dichotomized from a 7-point clinical status ordinal scale. A key secondary endpoint was mortality. RESULTS: After the inverse probability of treatment weighting procedure, 312 and 818 patients were counted in the remdesivir- and non-remdesivir-cohorts, respectively. At day 14, 74.4% of patients in the remdesivir-cohort had recovered versus 59.0% in the non-remdesivir-cohort (adjusted odds ratio [aOR] 2.03: 95% confidence interval [CI]: 1.34-3.08, P < .001). At day 14, 7.6% of patients in the remdesivir-cohort had died versus 12.5% in the non-remdesivir-cohort (aOR 0.38, 95% CI: .22-.68, P = .001). CONCLUSIONS: In this comparative analysis, by day 14, remdesivir was associated with significantly greater recovery and 62% reduced odds of death versus standard-of-care treatment in patients with severe COVID-19. CLINICAL TRIALS REGISTRATION: NCT04292899 and EUPAS34303.

Hepatocellular carcinoma and other complications of non-alcoholic fatty liver disease and non-alcoholic steatohepatitis in Japan: A structured review of published works.

AIMS: Hepatocellular carcinoma (HCC) is a significant cause of morbidity and mortality in Japan. As the treatment of viral hepatitis improves, non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) are rapidly becoming leading causes of HCC in Japan. This structured review aims to characterize the morbidity and mortality of HCC and other malignant and non-malignant complications among Japanese NAFLD and NASH patients. METHODS: An English and Japanese structured search of published works was undertaken in PubMed, Embase, and Ichushi Web databases, identifying 6553 studies, 34 of which met predefined inclusion criteria. RESULTS: Hepatocellular carcinoma was the most common incident malignancy among NAFLD/NASH patients, with higher incidence in patients with advanced/severe fibrosis (F3/F4) of 10.5%-20.0%. Although NASH results in a lower HCC cumulative incidence than hepatitis C virus (HCV) (11.3% vs. 30.5%), they have similar impacts on health outcomes, including overall mortality. Among Japanese NASH patients, HCC was found to be the main driver of mortality (40.0% in 2.7 years in NASH-HCC). With longer follow-up, higher mortality rates are observed in F3/4 patients: 25.0% in NASH F3/F4 versus 0.0% in NASH F0/2 over 7.7 years. The NASH-HCC patients also have a higher post-operative mortality than HCV-HCC patients. Additionally, NAFLD/NASH patients had higher rates of cardiovascular disease than non-NAFLD/NASH controls, and slightly higher rates of gastric cancer than HCV patients. CONCLUSION: Hepatocellular carcinoma is the most common malignancy and cause of death among NAFLD/NASH patients in Japan, with higher mortality observed among those with advanced disease and complications. Early identification and effective treatments are needed.

Increasing comorbidities in a South Korea insured population-based cohort of patients with chronic hepatitis B.

BACKGROUND: It is controversial whether chronic hepatitis B (CHB) patients have more non-liver comorbidities than non-CHB subjects. AIM: To characterise the demographics, comorbidity and health utilisation of CHB patients in South Korea and compare them to matched controls. METHODS: Using the Health Insurance Review & Assessment Service (HIRA) 2007-2016 database, adult patients with claims for CHB analysed. CHB cases and non-CHB controls matched in a 1:4 ratio using propensity score matching method. RESULTS: The age of CHB patients significantly increased from a mean 46.9 years in 2007 to 52.3 years in 2016. The proportions of persons having both liver-related and non-liver related comorbidities were higher in CHB patients compared to matched controls (dyslipidaemia [37.23% vs 23.77%, P < 0.0001], hypertension [29.39% vs 25.27%, P < 0.0001] chronic kidney disease (CKD) [3.02% vs 1.14%, P < 0.0001] and osteoporosis/fracture [OF] [4.09% vs 3.23%, P < 0.0001]). Approximately 50% of CHB patients had more than one comorbidity among CKD, diabetes, DLP, and OF. The odds of CKD in CHB patients were 1.42 times higher, and the odds of OF in CHB patients were 1.09 times higher than matched controls after adjustment for confounders (P < 0.0001). CONCLUSION: Prevalence of liver as well as non-liver comorbidities in patients with CHB was higher than matched controls and increased over time.

Hepatitis C virus cure with direct acting antivirals: Clinical, economic, societal and patient value for China.

About 10 million people in China are infected with hepatitis C virus (HCV), with the seroprevalence of anti-HCV in the general population estimated at 0.6%. Delaying effective treatment of chronic hepatitis C (CHC) is associated with liver disease progression, cirrhosis, hepatocellular carcinoma, and liver-related mortality. The extrahepatic manifestations of CHC further add to the disease burden of patients. Managing CHC-related advanced liver diseases and systemic manifestations are costly for both the healthcare system and society. Loss of work productivity due to reduced well-being and quality of life in CHC patients further compounds the economic burden of the disease. Traditionally, pegylated-interferon plus ribavirin (PR) was the standard of care. However, a substantial number of patients are ineligible for PR treatment, and only 40%-75% achieved sustained virologic response. Furthermore, PR is associated with impairment of patient-reported outcomes (PROs), high rates of adverse events, and poor adherence. With the advent of direct acting antivirals (DAAs), the treatment of CHC patients has been revolutionized. DAAs have broader eligible patient populations, higher efficacy, better PRO profiles, fewer adverse events, and better adherence rates, thereby making it possible to cure a large proportion of all CHC patients. This article aims to provide a comprehensive evaluation on the value of effective, curative hepatitis C treatment from the clinical, economic, societal, and patient experience perspectives, with a focus on recent data from China, supplemented with other Asian and international experiences where China data are not available.

Cost-Utility of a Two-Dose Human Papillomavirus Vaccination Programme Added to Cervical Cancer Screening Compared with Cervical Cancer Screening Alone in Korea

Background: Cervical cancer is caused by the human papillomavirus and is a leading cause of cancer death among young Korean women. Current screening programmes could benefit from the addition of HPV vaccination into their schedule to help reduce disease burden. Two-dose vaccination schedules targeting HPV types 16 and 18, which are responsible for most cervical cancer cases, have recently been approved. Of the two available vaccines, AS04-adjuvanted HPV16/18 vaccine (AS04-HPV16/18v) provides greater protection against non-vaccine oncogenic HPV, while HPV-6/11/16/18 vaccine (4vHPVv) provides protection against genital warts. Methods: The health and economic consequences of introducing a two-dose HPV vaccination programme in 12-year-old girls together with screening were assessed in the Korean healthcare setting using a previously-published Markov model. Results: Compared with screening alone, AS04-HPV16/18v was cost-effective (incremental cost-effectiveness ratio below and within the Korean Won [KRW] 20-30 million treshold). When comparing the two vaccines, at 3% discount rate, AS04-HPV16/18v dominated 4vHPVv (i.e., provided 174 more quality-adjusted life-years (QALYs), 304 more life-years (LYs) and cost-savings of KRW 980 million). At a 5% discount rate, AS04-HPV16/18v provided comparable QALYs (albeit 5 fewer), 105 more LYs and cost-savings of KRW 292 million compared with 4vHPVv. Results were particularly sensitive to the discount rate used, as the health benefits of preventing cervical cancer are observed much later than those of preventing genital warts. Conclusion: For the Korean setting, HPV vaccination with a two-dose schedule is a cost-effective option, and AS04-HPV16/18v is likely to offer better health outcomes at a cost-saving compared with 4vHPVv.

Comparative Cost-Effectiveness Analysis of Two Different Two-Dose Human Papillomavirus Vaccines in Malaysia

Purpose: To comparatively evaluate the results of a 2-dose human papillomavirus (HPV) vaccination programme with the AS04-adjuvanted HPV16/18 vaccine (AS04-HPV-16/18v) or HPV-6/11/16/18 vaccine (4vHPVv), in addition to cervical cancer (CC) screening, in Malaysia. Methods: A lifetime Markov model replicating the natural history of HPV in 13-year-old girls was adapted to Malaysia to assess the impact of vaccination on pre-cancerous lesions, genital warts and CC cases, CC deaths, quality-adjusted life years (QALYs), and costs from the perspective of the Malaysian Ministry of Health. Vaccine effectiveness was based on efficacy and HPV type distribution. Both vaccines were assumed to have equal efficacy against vaccine-type HPV but differed for protection against non-vaccine types. Vaccine price parity was used and health and cost outcomes were discounted at 3%/annum. Sensitivity analyses tested the robustness of the results. Results: The model predicted that AS04-HPV-16/18v would result in 361 fewer CC cases and 115 fewer CC deaths than 4vHPVv, whereas 4vHPVv averted 4,241 cases of genital warts over the cohort's lifetime. Discounted total costs showed savings of 18.50 million Malaysian Ringgits and 246 QALYs in favour of AS04-HPV-16/18v. In one-way sensitivity analyses, the discount rate was the most influential variable for costs and QALYs, but AS04-HPV- 16/18v remained dominant throughout. A two-way sensitivity analysis to assess the longevity of cross-protection for both vaccines confirmed the base-case. Conclusions: In Malaysia, the use of AS04-HPV-16/18v, in addition to screening, was modelled to be dominant over 4vHPVv, with greater estimated CC benefits and lower costs.

Cost-effectiveness of two-dose human papillomavirus vaccination in Singapore.

INTRODUCTION: Cervical cancer is the tenth most common cancer and the eighth most frequent cause of death among women in Singapore. As human papillomavirus (HPV) infection is the necessary cause of cervical cancer, the risk of cervical cancer can be substantially reduced through vaccination. This study was conducted to evaluate the cost-effectiveness of two-dose HPV vaccination as part of a national vaccination programme for 12-year-old girls in Singapore, from the perspective of the healthcare payer. METHODS: A lifetime Markov cohort model was used to evaluate the cost-effectiveness of introducing the AS04-adjuvanted HPV-16/18 vaccine (AS04-HPV-16/18v) to the current cervical screening programme in Singapore. Furthermore, the cost-effectiveness of the AS04-HPV-16/18v was compared with the HPV-6/11/16/18 vaccine (4vHPV). Model inputs were derived from local data, where possible, and validated by clinical experts in Singapore. RESULTS: Introduction of the AS04-HPV-16/18v in Singapore was shown to prevent 137 cervical cancer cases and 48 cervical cancer deaths when compared with screening alone. This resulted in an incremental cost-effectiveness ratio of SGD 12,645 per quality-adjusted life year (QALY) gained, which is cost-effective according to the World Health Organization threshold for Singapore. When discounted at 3%, AS04-HPV-16/18v was dominant over 4vHPV, with cost savings of SGD 80,559 and 28 additional QALYs gained. In the one-way sensitivity analysis, AS04-HPV-16/18v remained cost-effective compared with screening alone and dominant compared with 4vHPV. CONCLUSION: AS04-HPV-16/18v is the most cost-effective choice for reducing the burden of cervical cancer through universal mass vaccination for 12-year-old girls in Singapore.

Cost-effectiveness analysis of AS04-adjuvanted human papillomavirus 16/18 vaccine compared with human papillomavirus 6/11/16/18 vaccine in the Philippines, with the new 2-dose schedule.

Cervical cancer (CC) is the second leading cause of cancer death among Filipino women. Human papillomavirus (HPV) vaccination protects against CC. Two vaccines (AS04-HPV-16/18 and 4vHPV) are approved in the Philippines; they were originally developed for a 3-dose (3D) administration and have recently been approved in a 2-dose schedule (2D). This study aims to evaluate the cost-effectiveness of HPV vaccination of 13-year-old Filipino girls, in addition to current screening, in the new 2D schedule. An existing static lifetime, one-year cycle Markov cohort model was adapted to the Philippine settings to simulate the natural history of low-risk and oncogenic HPV infection, the effects of screening and vaccination of a 13-year-old girls cohort vaccinated with either the 2D-AS04-HPV-16/18 or 2D-4vHPV assuming a 100% vaccination coverage. Incremental cost, quality-adjusted life year (QALY) and cost-effectiveness were derived from these estimates. Input data were obtained from published sources and Delphi panel, using country-specific data where possible. Sensitivity analyses were performed to assess the robustness of the model. The model estimated that 2D-AS04-HPV-16/18 prevented 986 additional CC cases and 399 CC deaths (undiscounted), as well as 555 increased QALY (discounted), and save 228.1 million Philippine pesos (PHP) compared with the 2D-4vHPV. In conclusion, AS04-HPV-16/18 is shown to be dominant over 4vHPV in the Philippines, with greater estimated health benefits and lower costs.

Managing the double burden: pregnancy and labor-intensive time use in rural China, Mexico, and Tanzania.

Labor-intensive work is often a way of life for women living in rural areas of developing countries. The physical exertion involved in such work may result in poor health outcomes for mothers and infants when continued through pregnancy. Using longitudinal data from China, Mexico, and Tanzania, we examine the relationship between pregnancy and four time-use outcomes, measured as hours spent in the past week on: (1) housework, (2) caregiving, (3) agricultural work, and (4) self-employment or nonagricultural work outside the home. An individual fixed-effects approach is adopted to overcome the potential time-invariant woman-level endogeneity of pregnancy status. With few exceptions, we do not find significantly different time-use patterns between pregnant and nonpregnant women. The assumption that women decrease labor-intensive work in developing countries during pregnancy needs revisiting and may have implications for both women's livelihood programming and assistance during childbearing periods.

Child welfare agency ties to providers and schools and substance abuse treatment use by adolescents.

Policy makers and advocates are increasingly encouraging child-serving organizations to work together. This study examined how child welfare agency ties with substance abuse treatment providers and schools correlated with substance abuse treatment for adolescents receiving child protective services. A sample of adolescents with substance use risk was extracted from a national survey of families engaged with child welfare. Logistic regressions with adjustments for complex survey design used child welfare agency ties to substance abuse treatment providers and schools to predict treatment. As expected, adolescents were more likely to report treatment when child protective services and substance abuse treatment were in the same agency and when child welfare agency directors reported joint planning with schools. However, child welfare agency agreements with substance abuse treatment providers were negatively associated with treatment. This unexpected finding implies that agencies may sometimes cooperate to address problems and to improve service utilization.

Trends in behavioral health care service provision by community health centers, 1998-2007.

OBJECTIVE: The federal government boosted support for community health centers in medically underserved areas in 2002-2007. This investigation compared trends in behavioral health services provided by community health centers nationwide during the first several years of that initiative with immediately prior trends. METHODS: Data were extracted from the Health Resources and Services Administration's Uniform Data System on community health centers for 1998-2007 (2007, N=1,067). Regression analyses revealed trends in individual community health centers' likelihood of providing on-site specialty mental health care, crisis services, and substance abuse treatment. Aggregate data were used to show national trends in numbers of behavioral health encounters, patients, and encounters per patient. RESULTS: The number of federally funded community health centers increased 43% between 2001 and 2007, from 748 to 1,067, over twice the annual growth rate between 1998 and 2001. However, trends in individual community health centers' likelihood of providing different types of behavioral health care were generally consistent across the two time periods. In 2007, 77% of community health centers offered specialty mental health services, 20% offered 24-hour crisis intervention services, and 51% offered substance abuse treatment. The mean number of mental health encounters per mental health patient at community health centers in 2007 was 2.9. CONCLUSIONS: The behavioral health care safety net has widened through rapid recent growth in the number of community health centers as well as a continuing increase in the proportion offering specialty mental health services.

Factors Associated With Use of ASAM Criteria and Service Provision in a National Sample of Outpatient Substance Abuse Treatment Units.

Standardized patient placement criteria such as those developed by the American Society of Addiction Medicine are increasingly common in substance abuse treatment, but it is unclear what factors are associated with their use or with treatment units' provision of related services. This study examined these issues in the context of a national survey of outpatient substance abuse treatment units. Regressions using 2005 data revealed that both public and private managed care were associated with a greater likelihood of using American Society of Addiction Medicine criteria to develop client treatment plans. However, only public managed care was associated with a greater likelihood of offering more resource-intensive services. Associations between client population severity and resource-intensive service provision were sparse but positive.
