Trends of public health research output from India during 2001-2008.

ABSTRACT:

Background

An understanding of how public health research output from India is changing in relation to the disease burden and public health priorities is required in order to inform relevant research development. We therefore studied the trends in the public health research output from India during 2001-2008 that was readily available in the public domain.

Methods

The scope and type of the published research from India in 2007 that was included in the PubMed database was assessed and compared with a previous similar assessment for 2002. Papers were classified based on the review of abstracts and original public health research papers were assessed in detail. Impact factors for the journals were used to compute quality-adjusted research output. The websites of governmental organizations, academic and research institutions and international organizations were searched in order to identify and review reports on original public health research produced in India from 2001 to 2008. The reports were classified based on the topics covered and quality and their trends over time were assessed.

Results

The number of original health research papers from India in PubMed doubled from 4494 in 2002 to 9066 in 2007. This included a 3.1-fold increase in public health research papers, but these comprised only 5% of the total papers in 2007. Within public health, the increase was lowest for the health system and policy category. Several major causes of disease burden in India continued to be underrepresented in the quality-adjusted public health research output in 2007. The number of papers evaluating population health interventions increased from 2002 to 2007, but there were none on the leading non-communicable causes of disease burden or on road traffic injuries. The number of identified original public health research reports increased by 64.7% from 204 in 2001-2004 to 336 in 2005-2008. The proportion of reports on reproductive and child health was very high but decreased slightly from 38.7% of the total in 2001-2004 to 31.5% in 2005-2008 (P = 0.09); those on the leading chronic non-communicable conditions and injuries increased from 6.4% to 13.4% (P = 0.01) but this was still much lower than their contribution to the disease burden. Health system/policy issues were the topic in 27.4% reports but health information issues were covered in a miniscule 0.6% reports. The proportion of reports that were evaluations increased slightly from 26% in 2001-2004 to 31.5% in 2005-2008, with this proportion being higher among the reports commissioned by international organizations (P < 0.001). The proportion of reports commissioned by Indian governmental organizations alone, or in collaboration with international organizations, doubled from 2001-2004 to 2005-2008 (P < 0.001). Only 25% of the total 540 reports had a quality score of adequate or better. The quality of reports produced by collaborations between Indian and international organizations was higher than those produced by Indian or international organizations alone (P < 0.001).

Conclusion

This is the first analysis from India that includes research reports in addition to published papers. It provides the most up-to-date understanding of public health research output from India. The increase in available public health research output and the increase in commissioning of this research by Indian governmental organizations are encouraging. However, the distribution of research topics and the quality of research reports continue to be unsatisfactory. It is necessary for health policy to address these continuing deficits in public health research in order to reduce the very large disease burden in India.

Project description:Coronary revascularization is among the most common hospital-based major interventional procedures performed in the United States. It is uncertain how new revascularization technologies, new clinical evidence from trials, and updated clinical guidelines have influenced the volume and distribution of coronary revascularizations over the past decade.To examine national time trends in the rates and types of coronary revascularizations.A serial cross-sectional study with time trends of patients undergoing coronary artery bypass graft (CABG) surgery or percutaneous coronary interventions (PCIs) between 2001 and 2008 at US hospitals in the Healthcare Cost and Utilization Project's Nationwide Inpatient Sample, which reports inpatient coronary revascularizations. These data were supplemented by Medicare outpatient hospital claims.Annual procedure rates of coronary revascularizations, CABG surgery, and PCI.A 15% decrease (P < .001) in the annual rate of coronary revascularizations was observed from 2001-2002 to 2007-2008. The annual CABG surgery rate decreased steadily from 1742 (95% confidence interval [CI], 1663-1825) CABG surgeries per million adults per year in 2001-2002 to 1081 (95% CI, 1032-1133) CABG surgeries per million adults per year in 2007-2008 (P < .001), but PCI rates did not significantly change (3827 [95% CI, 3578-4092] PCI per million adults per year in 2001-2002 vs 3667 [95% CI, 3429-3922] PCI per million adults per year in 2007-2008, P = .74). Between 2001 and 2008, the number of hospitals in the Nationwide Inpatient Sample providing CABG surgery increased by 12% (212 in 2001 vs 241 in 2008, P = .03), and the number of PCI hospitals increased by 26% (246 in 2001 vs 331 in 2008, P < .001). The median CABG surgery caseload per hospital decreased by 28% (median [interquartile range], 253 [161-458] in 2001 vs 183 [98-292] in 2008; P < .001) and the number of CABG surgery hospitals providing fewer than 100 CABG surgeries per year increased from 23 (11%) in 2001 to 62 (26%) in 2008 (P < .001).In US hospitals between 2001 and 2008, a substantial decrease in CABG surgery utilization rates was observed, but PCI utilization rates remained unchanged.

Project description:IntroductionHealth research is one mechanism to improve population-level health and should generally match the health needs of populations. However, there have been limited data to assess the trends in national-level cardiovascular research output, even as cardiovascular disease [CVD] has become the leading cause of morbidity and mortality worldwide.Materials and methodsWe performed a time trends analysis of cardiovascular research publications (1999-2008) downloaded from Web of Knowledge using a iteratively-tested cardiovascular bibliometric filter with >90% precision and recall. We evaluated cardiovascular research publications, five-year running actual citation indices [ACIs], and degree of international collaboration measured through the ratio of the fractional count of addresses from one country against all addresses for each publication.Results and discussionGlobal cardiovascular publication volume increased from 40 661 publications in 1999 to 55 284 publications in 2008, which represents a 36% increase. The proportion of cardiovascular publications from high-income, Organization for Economic Cooperation and Development [OECD] countries declined from 93% to 84% of the total share over the study period. High-income, OECD countries generally had higher fractional counts, which suggest less international collaboration, than lower income countries from 1999-2008. There was an inverse relationship between cardiovascular publications and age-standardized CVD morbidity and mortality rates, but a direct, curvilinear relationship between cardiovascular publications and Human Development Index from 1999-2008.ConclusionsCardiovascular health research output has increased substantially in the past decade, with a greater share of citations being published from low- and middle-income countries. However, low- and middle-income countries with the higher burdens of cardiovascular disease continue to have lower research output than high-income countries, and thus require targeted research investments to improve cardiovascular health.

Project description:In many Western countries, including Australia, construction workers have been identified as being at elevated risk of suicide compared to other workers. A variety of suicide prevention initiatives have been implemented and expanded to reduce suicide in this occupational group; however, the net effect of these is unknown. Using 19 years of national suicide data, this study examined the suicide mortality of Australian male construction workers relative to all other working males, and compared suicide rates over time between the two groups. Age-standardized suicide rates were calculated for construction workers and those employed in other occupations. 2001–2019 trends in age-standardized rates of suicide mortality were analyzed by joinpoint regression analysis. The annual average percentage change (AAPC) measure was calculated for both groups to quantify change over time within each group, complemented by a pair-wise AAPC comparison of changes in trends between the two groups over the 2001–2019 period. Australian male construction workers' overall age-standardized suicide rate was 26.6 per 100,000 persons compared to 13.2 per 100,000 for male workers employed in other occupations (pooled over the entire 2001–2019 period). Over time, the suicide mortality rate declined in both construction workers and those working in other occupations; however, the decline in suicide mortality was greater in construction workers (AAPC: −3.0; 95%CI −4.0, −2.0) compared to other workers (AAPC: 1.5; 95%CI −2.1, −1.0). The AAPC pair-wise comparison showed a significant difference between the rate of decline among construction versus other workers over the 19-year study period (AAPC: −1.4; 95%CI 0.4, 2.5), confirming a rapid decline among construction versus other male workers. This study provides evidence of a decline in suicide rates among Australian construction workers over the last two decades. This decline may be attributable to the combined effects of population-wide, male-specific, and sector-specific suicide prevention efforts over this same period, suggesting that the continuation or expansion of such efforts may lead to further declines.
