Income and mental health
RESUMO: A enorme carga e o sofrimento provocado pelas doenças mentais no mundo tornam imperioso conhecer melhor os seus determinantes. Combater as desigualdades em saude
tornou-‐se uma prioridadade de saúde publica, mas e necessário estabelecer as suas vias
causais para ser possível implementar intervenções e politicas efetivas. A literatura cientifica tem sugerido a importância dos determinantes sociais na etiologia e evolucao
das principais doenças mentais e do suicidio, com especial enfase no papel da desvantagem social. Ainda assim, o papel dos factores psicossociais na saúde mental,
e especificamente o papel do rendimento e da sua distribuição não tem sido investigado
no meu pais, Portugal. No meu projecto de investigação proponho‐me a estudar se em
Portugal existe uma associação entre as doenças mentais e o rendimento absoluto e
relativo. Pretendo usar os dados do primeiro inquérito epidemiológico sobre saude
mental realizado em Portugal,um inquérito nacional transversal no domicilio que
foi conduzido em 2009, integrado no WHO World Mental Health Survey Consortium.
Nesta tese de mestrado apresento os resultados da minha revisão da literatura
Sobre a relação entre oestatuto socio-economico e a saúde mental e esboço uma
proposta de pesquisa para continuar a investigar estetema. A evidencia que apresento
mostra que a exposição aum vasto leque de riscos psicossociais, como o baixo rendimento,
a educação limitada e o estatuto ocupacionalbaixo,aumenta a probabilidade de desenvolver problemas de saúde mental.. As diferencas em saúde seguem um gradiente
social, com piores resultados de saúde a medida que a posição na hierarquia social
diminui. Tambem sumarizo a literatura sobre o papel do contexto na produção de
desigualdades em saúde para alem das características individuais. Tem especial interesse
o potencial efeito na saúde do rendimento relativo e a importância da distribuição dos
rendimentos como determinante de saude.
Finalmente, delineio os possíveis mecanismos através dos quais o estatuto socio-economico contribui para as disparidades em saúde.-------------------ABSTRACT: The enormous burden and suffering from mental disorders worldwide
makes it imperative to better understand its determinants. Tackling nhealth inequalities
has become a public health priority, but it is necessary to establish their causalpathways
in order to implement effective interventions and policies. Scientific literature has suggested the importance of social determinants in the aetiology and course of major
mental disorders and suicide, with special emphasis on the role of social disadvantage.
Nevertheless, the role of psychosocial factors on mental health, and specifically the role
of income and its distribution, has not been researched in my home country, Portugal. In
my research project I propose to study whether in Portugal there is an association between mental disorders and absolute and relative income. I intend to use data from the
first Portuguese Mental Health Survey, a national cross-sectional household survey that
was conducted in 2009, integrated in the WHO World Mental Health Survey Consortium.
In this masters thesis I present the results of my literature review on the relation between
Socioeconomic status and mental health and outline a research proposal to further nvestigate this topic. The body of evidence that I present shows that exposure to a wide range of psychosocial risks, such as low income, limited education, and low occupational
status, increases the likelihood of mental health problems. Differences in health follow a social gradient, with worsening health as the position in the social ladder decreases.
I also summarize the literature on the role of context in producing health inequalities beyond individual characteristics. Of special interest is the potential health effect of relative income and the importance of income distribution as a health determinant.
Finally, I outline the various possible mechanisms for health disparities associated
with socioeconomic status
Patterns of use of mental health care in Portugal, before and during an economic crisis
RESUMO: Enquadramento: Eliminar a lacuna de cuidados de saúde mental deve ser uma prioridade de
saúde pública em todo o mundo, porque o baixo acesso a cuidados de qualidade é uma
negação de direitos humanos fundamentais e traduz-se em sofrimento, incapacidade e custos
económicos substanciais. Os períodos de crise económica podem aumentar ainda mais a
lacuna de tratamento, particularmente em grupos da população já vulneráveis. Organizada
em três fases de investigação, esta tese de doutoramento pretende contribuir para um
conhecimento mais sistematizado sobre a utilização dos cuidados de saúde mental em
Portugal e para uma melhor compreensão do impacto das crises económicas na utilização
dos cuidados de saúde mental. Na 1ª fase, foi feita uma revisão sistemática da evidência sobre
a associação entre períodos de crise económica e o uso de cuidados de saúde mental. Na 2ª
fase, foram avaliados o uso, os padrões e as barreiras à utilização de cuidados de saúde
mental em adultos com doença mental em Portugal e o impacto da Grande Recessão no
consumo de psicofármacos. Na 3ª fase foram explorados os fatores individuais e contextuais
que influenciam os padrões de internamento de doentes agudos, especificamente a demora
média, a readmissão e o internamento compulsivo, antes e durante uma crise económica.
Métodos: Na 1ª fase da investigação, foi realizada uma revisão sistemática da literatura
seguindo o PRISMA Statement. Na segunda fase, foram usados dados do Estudo
Epidemiológico Nacional de Saúde Mental (2008/09), um estudo transversal representativo
da população portuguesa (n=3849) parte da World Mental Health Survey Initiative, e dados
do Follow-up do Estudo Epidemiológico Nacional de Saúde Mental (2015/16) (n=911). Foram
efetuados quatro modelos de regressão logística múltipla para avaliar a associação entre
variáveis sociodemográficas e clínicas e ter recebido tratamento (sim/não) ou barreiras ao
tratamento (baixa necessidade percebida, barreiras atitudinais, barreiras estruturais) nos
participantes com doença mental em 2008/09, ajustando por idade, género e presença de
doença física. Foram efetuados modelos de equações de estimativas generalizadas múltiplas
para estimar a probabilidade na população de consumo de psicofármacos em 2008/2009 (T0)
e em 2015/2016 (T1), ajustando por educação. Foram estimados e interpretados odds ratios
em níveis específicos dos efeitos principais e dos termos de interação considerando as diferenças de consumo de psicofármacos em T0 e T1, de acordo com o género e a idade. A
3ª fase de investigação usou dados do projeto SMAILE, que estudou utentes das áreas de
influência de cinco serviços de Psiquiatria públicos com pelo menos um internamento em
2002, 2007 e 2012. Foram efetuados modelos de regressão logística múltipla para estimar a
associação entre demora média mais longa (≥ 17 dias) e readmissão (> 1 admissão) e os
fatores sociodemográficos, clínicos e contextuais em estudo. Além disso, foi utilizado um
modelo linear generalizado de Poisson para modelar o número esperado de internamentos
compulsivos em função das seguintes covariáveis: género, grupo etário, estado civil,
educação, situação profissional, presença de tentativa de suicídio, diagnóstico psiquiátrico,
ano de avaliação e serviço de Psiquiatria.
Resultados: Na 1ª fase foi encontrado que 1) os períodos de crise económica estão associados
a aumento da procura de cuidados gerais para problemas de saúde mental, com evidência
contraditória quanto à utilização de cuidados especializados psiquiátricos; 2) esses períodos
estão associados a maior consumo de psicofármacos e a aumento de internamentos por
doença mental, com resultados contraditórios na utilizaçãos de cuidados de saúde mental
por comportamento suicidário. Na 2ª fase foi encontrado que 1) a maioria dos participantes
(65,4%) com doença mental não recebeu tratamento; 2) o determinante mais importante da
utilização de serviços de saúde foi a presença de perturbação do humor, seguido da
incapacidade, sendo os participantes solteiros e os que têm ensino básico e secundário os
que menos acederam aos serviços de saúde; 3) as barreiras atitudinais foram as mais
frequentemente reportadas, seguidas da baixa necessidade percebida e das barreiras
estruturais; 4) a probabilidade de reportar barreiras atitudinais foi maior nos participantes com
níveis mais baixos de educação e menor nos participantes com perturbação por utilização de
substâncias; 5) a baixa necessidade percebida foi mais reportada por solteiros e menos
reportada por participantes com perturbação da ansiedade e do humor; 6) a probabilidade
de reportar barreiras estruturais foi maior nos participantes desempregados; 7) ajustando
para idade, género e educação, foi estimado que a probabilidade na população de consumir
qualquer psicofármaco em 2015/16 foi 1,5 vezes maior do que em 2008/09 (OR = 1,50; IC 95%:
1,13–2,01), particularmente para hipnóticos / sedativos (OR = 1,60; IC 95%: 1,14–2,25); 8) as
mulheres e os idosos apresentaram maior probabilidade de consumir qualquer psicofármaco,
mas a crise económica teve um impacto desproporcional nos homens e nos jovens. Na 3ª fase
da investigação, os principais resultados foram: 1) a demora média mais longa foi associada
a idade superior, diagnóstico de psicose e internamento compulsivo; 2) a demora média mais
curta foi associada a ser casado, ter ensino secundário, ter feito uma tentativa de suicídio, ter
o diagnóstico de perturbação de utilização de substâncias e “outras doenças mentais”, ter
sido internado em 2012 e pertencer à área de influência de dois dos serviços de Psiquiatria
avaliados (Hospital de Magalhães Lemos EPE e Centro Hospitalar Psiquiátrico de Lisboa); 3)
a maior probabilidade de readmissão foi associada a ser reformado, ter o diagnóstico de
psicose, ter internamento compulsivo e pertencer à área de influência de quatro dos serviços
de Psiquiatria avaliados (Hospital de Magalhães Lemos EPE, Centro Hospitalar Psiquiátrico
de Lisboa, Hospital Professor Doutor Fernando Fonseca EPE e Unidade Local de Saúde do
Baixo Alentejo EPE); 4) a menor probabilidade de readmissão foi associada a ter idade
superior e ter ensino secundário ou superior; 5) o aumento de internamento compulsivo foi
associado a sexo masculino, ensino secundário ou superior, diagnóstico psiquiátrico de
psicose e internamento em 2007 e em 2012; 6) a diminuição de internamento compulsivo foi
associada a ser casado ou coabitar, ter feito uma tentativa de suicídio e pertencer à área de
influência de três dos serviços de Psiquiatria avaliados (Hospital de Magalhães Lemos EPE,
Centro Hospitalar Psiquiátrico de Lisboa e Unidade Local de Saúde do Baixo Alentejo EPE).
Conclusões: Os resultados desta tese de doutoramento confirmam as elevadas necessidades
não satisfeitas de saúde mental em Portugal, sugerem quais são as principais barreiras aos
cuidados e identificam os subgrupos mais vulneráveis a essas barreiras e a padrões de
hospitalização mais graves. Esta evidência pode ajudar a estabelecer prioridades de ação
quando estamos a viver uma grave crise económica e há uma necessidade urgente de reduzir
a lacuna nos cuidados de saúde mental. O atual momento de interesse pela saúde mental
deve ser uma oportunidade para investir e melhorar a utilização dos recursos e a organização
dos serviços. As estratégias para melhorar a capacidade do setor da saúde mental para
responder às necessidades de saúde mental incluem modelos de cuidados mais próximos da
população, que facilitam a identificação precoce de problemas de saúde mental e a
implementação de intervenções integradas e psicossociais. Este objetivo poderá ser
alcançado com o desenvolvimento de uma rede mais robusta e ampla de equipas e de
serviços de saúde mental baseados na comunidade, a solução mais efetiva para melhorar a
continuidade de cuidados, reforçar a adesão ao tratamento, melhorar o apoio e a colaboração com as famílias e aprofundar a coordenação com os cuidados de saúde
primários e os serviços sociais. É também essencial melhorar a procura de ajuda,
implementando intervenções de literacia em saúde mental, usando tecnologias digitais e
incentivando o contacto interpessoal com pessoas com doença mental. Por último, mas não
menos importante, as pessoas com doença mental devem ser envolvidas em todos os aspetos
dos cuidados de saúde mental, com pleno reconhecimento de seus desejos e das suas
preferências e respeito pelos seus direitos humanos.ABSTRACT: I would like to thank my supervisor, Professor Benedetto Saraceno, for his warm support and

And to João, for all his support, understanding, and endless encouragement Background: Closing the mental health care gap should be at the top of the public health
agenda worldwide, because low access to quality care is a denial of fundamental human rights
and leads to substantial suffering, disability, and economic costs. Periods of economic crisis
might further increase the treatment gap, particularly in already vulnerable population groups.
Organised in three research phases, this doctoral thesis aims to contribute to a more
systematised knowledge about the use of mental health care in Portugal, and to a better
understanding of the impact of economic crises on the use of mental health care. A systematic
review of the current evidence on the association between periods of economic crisis and the
use of mental health care was conducted in the 1st phase. In the 2nd phase the use, patterns
and barriers to mental health care among adults with mental disorders in Portugal, and the
impact of the Great Recession on the use of psychotropic drugs were evaluated. The
individual and contextual factors that influence patterns of use of acute psychiatric inpatient
services, specifically length of hospital stay (LOS), readmission and involuntary hospitalisation,
before and during an economic crisis, were explored in the 3rd phase.
Methods: In the 1st research phase, a systematic literature review was carried out following the
PRISMA guidelines. In the 2nd phase research was conducted using data from the National
Mental Health Survey (2008/09), a nationally representative cross-sectional survey (n=3849)
part of the World Mental Health Survey Initiative, and from the National Mental Health Survey
Follow-up (2015/16) (n=911). Four multiple logistic regression models were performed to
evaluate the association between sociodemographic and clinical variables and having
received treatment (yes/no) or barriers to treatment (low perceived need, attitudinal barriers,
structural barriers) among the participants with any 12-month mental disorder in 2008/09,
adjusting for age, gender and presence of any physical disorder. Multiple generalised
estimating equations models were performed to estimate the population odds of consuming
psychotropic drugs in 2008/2009 (T0) and in 2015/2016 (T1), adjusting for education. Odds
ratios were estimated and interpreted at specific levels of the main effects and of interaction
terms considering differences in psychotropic drugs use in T0 and T1, according to gender
and age. The 3rd research phase used data from the SMAILE project which studied patients from the catchment areas of five public psychiatric services who had at least one admission
during 2002, 2007 and 2012. Multiple logistic regression models were used to estimate the
association between longer LOS (≥17 days) and readmission (>1 admission) with the
sociodemographic, clinical, and contextual factors under study. Additionally, a Poisson
generalised linear model was employed for modelling the expected number of involuntary
hospitalisations as a function of the following covariates: gender, age group, marital status,
education, employment status, suicide attempt, psychiatric diagnosis, year of evaluation and
psychiatric service.
Results: In the 1st phase the main findings were that 1) periods of economic crisis are linked to
an increase in seeking general help for mental health problems, with conflicting results
regarding the changes in the use of specialised psychiatric care; 2) these periods are
associated with a higher use of psychotropic drugs and an increase in hospital admissions for
mental disorders, with mixed evidence on the use of mental health care specifically due to
suicide behaviour. In the 2nd phase the main findings were that 1) the majority of participants
(65.4%) with a mental disorder did not receive treatment; 2) the most important determinant
of the use of health services was the presence of a mood disorder, followed by disability, while
single participants and those with basic or secondary education were the ones who least
accessed mental health care; 3) attitudinal barriers were the most commonly reported barrier
to treatment, followed by low perceived need and structural barriers; 4) attitudinal barriers
were more likely among participants with lower levels of education, and less likely among
participants with substance use disorders; 5) low perceived need was higher among single
people, and lower among those with anxiety and mood disorders; 6) structural barriers were
more likely among unemployed participants; 7) after adjusting for age, gender and education,
population odds of consuming any psychotropic drugs in 2015/16 were estimated to be 1.5
times higher than in 2008/09 (OR = 1.50; 95% CI: 1.13–2.01), particularly for
hypnotics/sedatives (OR = 1.60; 95% CI: 1.14–2.25); 8) women and older individuals presented
higher odds of consuming any psychotropic drugs, but the economic crisis had a
disproportionate impact on men and younger individuals. In the 3rd research phase the main
findings were that: 1) longer LOS was associated with older age, a diagnosis of psychosis, and
compulsory admission; 2) shorter LOS was associated with being married, having a secondary
education, having experienced a suicide attempt, having been diagnosed with a substance use disorder and “other mental disorders”, being admitted in 2012, and belonging to the
catchment area of two of the psychiatric services evaluated (Hospital de Magalhães Lemos
EPE and Centro Hospitalar Psiquiátrico de Lisboa); 3) higher odds of readmission were
associated with being retired, a diagnosis of psychosis, compulsory admission, and belonging
to the catchment area of four of the psychiatric services evaluated (Hospital de Magalhães
Lemos EPE, Centro Hospitalar Psiquiátrico de Lisboa, Hospital Professor Doutor Fernando
Fonseca EPE, and Unidade Local de Saúde do Baixo Alentejo EPE); 4) lower odds of
readmission were associated with older age and with having secondary or higher education;
5) an increase of involuntary hospitalisations was associated with male gender, secondary or
higher education, a psychiatric diagnosis of psychosis, and admission in 2007 and in 2012; 6)
a decrease in involuntary hospitalisations was associated with being married or cohabitating,
having experienced a suicide attempt, and belonging to the catchment area of three of the
psychiatric services evaluated (Hospital de Magalhães Lemos EPE, Centro Hospitalar
Psiquiátrico de Lisboa and Unidade Local de Saúde do Baixo Alentejo EPE).
Conclusions: The results of this doctoral thesis confirm the high unmet mental health needs
in Portugal, suggest what are the main barriers to care, and identify the subgroups most
vulnerable to these barriers and to more severe hospitalisation patterns. This evidence might
help to establish priorities for action when we are experiencing a serious economic crisis and
there is an urgent need to reduce the mental health care gap. The current momentum of
interest in mental health should be an opportunity to invest and improve the use of resources
and the organisation of services. Strategies to improve the capacity of the mental health
sector to respond to the mental health demands include models of care that are closer to the
population, facilitating the early identification of mental health problems and the
implementation of integrated and psychosocial interventions. This could be achieved by
developing a more robust and widespread network of community-based mental health teams
and services, the best solution to enhance continuity of care, to reinforce treatment
compliance, to improve support for and collaboration with families, and to improve
coordination with primary care and social services. It is also essential to improve help-seeking
attitudes by implementing mental health literacy interventions, using digital technologies, and
encouraging interpersonal contact with people with mental disorders. Last but not least,people with mental disorders should be engaged in all aspects of mental health care, with the
full recognition of their desires and preferences and respect for their human right
Uso da cimicifuga racemosa para tratamento dos sintomas no climatério: Use of racemosa cimicifuga to treat climate symptoms
Introdução: O climatério é uma fase de transição na vida das mulheres, com manifestações clínicas como irritabilidade, fogachos e a diminuição da libido. A partir dos 40 anos, há o início das alterações físicas e psicossociais nas mulheres, e, tal faixa etária aliada ao padrão menstrual alterado indicam muitas vezes o diagnóstico do climatério. Sendo assim, há demandas de estratégias que melhorem a qualidade de vida, como as terapias adjuvantes. A fitoterapia é uma terapia adjuvante histórica e promissora, nesse âmbito, a Cimicifuga Racemosa (CR) se destaca pelas possíveis propriedades sobre os sintomas climatéricos durante essa fase. Objetivo: O presente artigo tem por objetivo avaliar os benefícios do uso da CR em mulheres climatéricas avaliando os resultados obtidos desse fitoterápico de acordo com a literatura. Metodologia: Trata-se de uma revisão bibliográfica integrativa, qualitativa e retrospectiva de estudos nacionais e internacionais das bases de dados: Biblioteca Virtual em Saúde, Scientific Electronic Library Online e Medical Literature Analysis and Retrieval System Online. A fórmula de busca foi composta pelos descritores: “Cimicifuga”, “Fitoterapia”, “Climatério” e “Saúde da Mulher” dos Descritores em Ciências da Saúde (DeCS) aliado aos operadores booleanos “OR” e “AND”, resultando em 5989 artigos, após o uso de critérios de inclusão e exclusão, 10 artigos dos últimos 6 anos foram selecionados para compor essa revisão. Resultados e Discussão: Dos artigos selecionados para compor essa revisão, 37,5% abordaram o uso do extrato da CR no controle dos sintomas da menopausa. Outros 25% retrataram sobre o uso da CR em relação a parâmetros metabólicos, bem como, suas consequências em relação à perda ponderal. Além disso, 12,5% relataram sobre um ensaio clínico randomizado que analisou os efeitos dos ativos botânicos na pele e antioxidante nas mulheres pós menopausa. Outrossim, 12,5% analisaram sobre o uso da CR na síndrome menopausa causada por LHRH-a no câncer de mama, e 12,5% dos estudos realizaram uma revisão do desenvolvimento ao longo dos 60 anos de medicamentos a partir do extrato da CR. Desta forma, a CR é destacada como relevante no alívio das ondas de calor, sudorese, comprometimento do sono e irritabilidade, nos distúrbios ginecológicos, bem como pode contribuir com a modulação de receptores cerebrais de áreas relacionadas ao sono e ao humor, tais como, os receptores de dopamina e serotonina. Conclusão: A CR demonstra ser eficaz nos sintomas do climatério, todavia, configura-se necessário mais estudos para consolidar as propriedades e benefícios do fitoterápico

NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the Neotropics
Xenarthrans—anteaters, sloths, and armadillos—have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, 10 anteaters, and 6 sloths. Our data set includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae (3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data on Dasypus pilosus (Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized, but new genetic studies have revealed that the group is represented by seven species. In this data paper, we compiled a total of 42,528 records of 31 species, represented by occurrence and quantitative data, totaling 24,847 unique georeferenced records. The geographic range is from the southern United States, Mexico, and Caribbean countries at the northern portion of the Neotropics, to the austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n = 5,941), and Cyclopes sp. have the fewest (n = 240). The armadillo species with the most data is Dasypus novemcinctus (n = 11,588), and the fewest data are recorded for Calyptophractus retusus (n = 33). With regard to sloth species, Bradypus variegatus has the most records (n = 962), and Bradypus pygmaeus has the fewest (n = 12). Our main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if we integrate the xenarthran data with other data sets of Neotropical Series that will become available very soon (i.e., Neotropical Carnivores, Neotropical Invasive Mammals, and Neotropical Hunters and Dogs). Therefore, studies on trophic cascades, hunting pressure, habitat loss, fragmentation effects, species invasion, and climate change effects will be possible with the Neotropical Xenarthrans data set. Please cite this data paper when using its data in publications. We also request that researchers and teachers inform us of how they are using these data
Characterisation of microbial attack on archaeological bone
As part of an EU funded project to investigate the factors influencing bone preservation in the archaeological record, more than 250 bones from 41 archaeological sites in five countries spanning four climatic regions were studied for diagenetic alteration. Sites were selected to cover a range of environmental conditions and archaeological contexts. Microscopic and physical (mercury intrusion porosimetry) analyses of these bones revealed that the majority (68%) had suffered microbial attack. Furthermore, significant differences were found between animal and human bone in both the state of preservation and the type of microbial attack present. These differences in preservation might result from differences in early taphonomy of the bones. © 2003 Elsevier Science Ltd. All rights reserved

Anastomotic leak affects 8 per cent of patients after right colectomy with a 10-fold increased risk of postoperative death. The EAGLE study aimed to develop and test whether an international, standardized quality improvement intervention could reduce anastomotic leaks.
Methods
The internationally intended protocol, iteratively co-developed by a multistage Delphi process, comprised an online educational module introducing risk stratification, an intraoperative checklist, and harmonized surgical techniques. Clusters (hospital teams) were randomized to one of three arms with varied sequences of intervention/data collection by a derived stepped-wedge batch design (at least 18 hospital teams per batch). Patients were blinded to the study allocation. Low- and middle-income country enrolment was encouraged. The primary outcome (assessed by intention to treat) was anastomotic leak rate, and subgroup analyses by module completion (at least 80 per cent of surgeons, high engagement; less than 50 per cent, low engagement) were preplanned.
Results
A total 355 hospital teams registered, with 332 from 64 countries (39.2 per cent low and middle income) included in the final analysis. The online modules were completed by half of the surgeons (2143 of 4411). The primary analysis included 3039 of the 3268 patients recruited (206 patients had no anastomosis and 23 were lost to follow-up), with anastomotic leaks arising before and after the intervention in 10.1 and 9.6 per cent respectively (adjusted OR 0.87, 95 per cent c.i. 0.59 to 1.30; P = 0.498). The proportion of surgeons completing the educational modules was an influence: the leak rate decreased from 12.2 per cent (61 of 500) before intervention to 5.1 per cent (24 of 473) after intervention in high-engagement centres (adjusted OR 0.36, 0.20 to 0.64; P < 0.001), but this was not observed in low-engagement hospitals (8.3 per cent (59 of 714) and 13.8 per cent (61 of 443) respectively; adjusted OR 2.09, 1.31 to 3.31).
Conclusion
Completion of globally available digital training by engaged teams can alter anastomotic leak rates. Registration number: NCT04270721 (http://www.clinicaltrials.gov)
Global variation in postoperative mortality and complications after cancer surgery: a multicentre, prospective cohort study in 82 countries
© 2021 The Author(s). Published by Elsevier Ltd. This is an Open Access article under the CC BY-NC-ND 4.0 licenseBackground: 80% of individuals with cancer will require a surgical procedure, yet little comparative data exist on early outcomes in low-income and middle-income countries (LMICs). We compared postoperative outcomes in breast, colorectal, and gastric cancer surgery in hospitals worldwide, focusing on the effect of disease stage and complications on postoperative mortality. Methods: This was a multicentre, international prospective cohort study of consecutive adult patients undergoing surgery for primary breast, colorectal, or gastric cancer requiring a skin incision done under general or neuraxial anaesthesia. The primary outcome was death or major complication within 30 days of surgery. Multilevel logistic regression determined relationships within three-level nested models of patients within hospitals and countries. Hospital-level infrastructure effects were explored with three-way mediation analyses. This study was registered with ClinicalTrials.gov, NCT03471494. Findings: Between April 1, 2018, and Jan 31, 2019, we enrolled 15 958 patients from 428 hospitals in 82 countries (high income 9106 patients, 31 countries; upper-middle income 2721 patients, 23 countries; or lower-middle income 4131 patients, 28 countries). Patients in LMICs presented with more advanced disease compared with patients in high-income countries. 30-day mortality was higher for gastric cancer in low-income or lower-middle-income countries (adjusted odds ratio 3·72, 95% CI 1·70–8·16) and for colorectal cancer in low-income or lower-middle-income countries (4·59, 2·39–8·80) and upper-middle-income countries (2·06, 1·11–3·83). No difference in 30-day mortality was seen in breast cancer. The proportion of patients who died after a major complication was greatest in low-income or lower-middle-income countries (6·15, 3·26–11·59) and upper-middle-income countries (3·89, 2·08–7·29). Postoperative death after complications was partly explained by patient factors (60%) and partly by hospital or country (40%). The absence of consistently available postoperative care facilities was associated with seven to 10 more deaths per 100 major complications in LMICs. Cancer stage alone explained little of the early variation in mortality or postoperative complications. Interpretation: Higher levels of mortality after cancer surgery in LMICs was not fully explained by later presentation of disease. The capacity to rescue patients from surgical complications is a tangible opportunity for meaningful intervention. Early death after cancer surgery might be reduced by policies focusing on strengthening perioperative care systems to detect and intervene in common complications.

Effects of hospital facilities on patient outcomes after cancer surgery: an international, prospective, observational study
© 2022 The Author(s). Published by Elsevier Ltd. This is an Open Access article under the CC BY 4.0 licenseBackground: Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide. Methods: A multimethods analysis was performed as part of the GlobalSurg 3 study—a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital. Findings: Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3·85 [95% CI 2·58–5·75]; p<0·0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63·0% vs 82·7%; OR 0·35 [0·23–0·53]; p<0·0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer. Interpretation: Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised.
