Nosocomial COVID-19 infection in the era of vaccination and antiviral therapy.

BACKGROUND AND AIMS: Coronavirus disease 2019 (COVID-19) vaccination and antiviral therapies have altered the course of the COVID-19 pandemic through mitigating severe illness and death. However, immunocompromised, elderly and multimorbid patients remain at risk of poor outcomes and are overrepresented in hospital populations. The aim of this study was to describe the characteristics and outcomes of patients with nosocomial COVID-19 infection. METHODS: This was a retrospective, observational study of patients who acquired COVID-19 after 7 days of hospital admission within the Southern Adelaide Local Health Network (SALHN) in South Australia between 1 June 2022 and 30 November 2022. Data were ascertained from the electronic medical record and the South Australian registry of births, deaths and marriages. RESULTS: Of 1084 COVID-19 inpatient cases managed in SALHN, 295 (27%) were nosocomial, with 215 included in the study. The median age of patients was 80 years (interquartile range [IQR], 68-88 years), the median Charlson Comorbidity Index score was 5 (IQR, 4-7) and 6% were immunocompromised. Most nosocomial COVID-19 infections were of mild severity (81%). The 30-day all-cause mortality rate following COVID-19 infection was 6%, and, in most cases, a cause of death other than COVID-19 was recorded on the death certificate. CONCLUSION: The majority of cases of nosocomial COVID-19 infection were mild, with a lower mortality rate than in earlier studies. This finding is likely attributable to immunity through vaccination and prior infection, early antiviral therapy and attenuated severity of the Omicron variant. The high proportion of nosocomial infections supports ongoing infection control measures.

Sexual lives and reproductive health outcomes among persons with disabilities: a mixed-methods study in two districts of Ghana.

INTRODUCTION: People with disabilities (PwDs) constitute a large and diverse group within the global population, however, their sexual and reproductive health (SRH) needs are often neglected, particularly in low-and middle-income countries. This may result in adverse outcomes, such as sexually transmitted infections (STIs), unintended pregnancies, and experience of interpersonal violence (IV). This study aimed to assess the factors that influence the sexual lives of PwDs in two districts of Ghana. METHODS: A sequential explanatory mixed-methods study design was used to collect data from PwDs. Quantitative data were obtained from 402 respondents using a pretested questionnaire, and qualitative data gathered from 37 participants using in-depth interviews. The quantitative data were analysed using descriptive and inferential statistics, while the qualitative data were analysed using inductive thematic analysis. RESULTS: Most PwDs (91%) reported that they have ever had sex, which was associated with age, disability severity, and household size. The prevalence of poor SRH status, STIs, unintended pregnancy, pregnancy termination, and unsafe abortion were 10.5%, 5.7%, 6.4%, 21.6%, and 36.9% respectively. These outcomes were influenced by education, income, health insurance subscription, and proximity to a health facility. The prevalence of IV was 65%, which was related to disability type and severity. The qualitative data revealed five main themes: curiosity to engage in sexual activities, feelings of despair and insecurity with abled partners, preference for sexual relationships with other PwDs, IV and its perpetrators, and adverse SRH outcomes. CONCLUSION: The study findings indicate that most adult PwDs have ever had sex and they face various challenges in their sexual lives. They experience multiple forms of abuse and neglect from different perpetrators at different levels of society, which have negative impacts on their well-being. There is a need for comprehensive and inclusive interventions that address the SRH needs of PwDs, as well as the underlying social and structural factors that contribute to their vulnerability. Further research is recommended to explore the perspectives of stakeholders on how to improve the SRH outcomes of PwDs.

People with disabilities make up 16 percent of the world population, but their sexual and reproductive health (SRH) needs are often unmet, especially in poorer countries, contributing to adverse outcomes. This study assessed factors influencing the sex lives of PwDs in two districts of Ghana. Quantitative data were collected from 402 respondents, while qualitative data were collected from 37 participants. The results showed that age, severity of disability, and household size influence sexual activity. Many respondents also reported adverse SRH issues including STIs and unintended pregnancies. Sixty-five percent reported experiencing violence or abuse, which is related to their disability type and severity. The study also found that PwDs encounter many challenges in their sexual lives, including abuse and neglect. The findings suggest the need to pay attention to the sexual health needs and the social issues that make PwDs vulnerable to various abuses.

Descriptive feedback with targeted education to improve telephonic escalation of care: a simulation-based study.

BACKGROUND: Awareness of communication failures in healthcare has necessitated the implementation of standardized, validated handover tools such as Identification, Situation, Background, Assessment, Recommendation (ISBAR). Although educational sessions improve communication, the effectiveness of individualized care escalation communication training is unknown. The primary aim was to conduct a simulation-based study to assess individualized one-on-one communication training for junior medical doctors for improving care escalation in pediatric emergencies. The secondary aim was to assess the evaluation of the training. METHODS: The prospective observational study assessed participants pre- and post-intervention. In Session One, participants presented a written case scenario telephonically to two senior pediatricians. Fifty participants were scored using an 18-item checklist based on the ISBAR tool and "free text" responses. Immediately following case presentations, participants completed individualized one-on-one 30-minute educational sessions regarding self-reflection, didactic teaching, and constructive feedback based on the ISBAR. Session Two included a second case presentation and reassessment. We conducted qualitative analysis of supervisor's feedback on performance and trainee doctor's evaluation of the training. RESULTS: There was significant improvement in 8 of the 18 components of the ISBAR checklist. All elements of care escalation were significantly improved, and overall communication was higher post-intervention (P < 0.001); however, no improvement was noted in participants' explorations of differential diagnoses (P = 0.263). The qualitative analysis identified themes of improved urgency in seeking senior support and conversational clarity from supervisors, and improved intervention quality and self-confidence from participants. CONCLUSIONS: Individualized communication training may improve pediatric emergency care escalation and communication among junior doctors.

Prevalence of hepatitis B virus amongst refugees, asylum seekers and internally displaced persons in low- and middle-income countries: A systematic review.

Hepatitis B, caused by the hepatitis B virus (HBV), is a global public health issue that affects 290 million people worldwide. Most people with hepatitis B are in low- and middle-income countries (LMIC), where health systems and resources are often constrained. Refugees, asylum seekers and internally displaced persons (IDPs) often face barriers in seeking health care and are a priority population at risk of hepatitis B. No systematic review to date has evaluated the prevalence of hepatitis B amongst refugees in in LMIC. We undertook a systematic review of the literature identifying 28 studies addressing this topic. Though few studies on this topic exist, the available evidence suggests a high prevalence amongst refugees in LMIC, with wide variation between and within countries. Possible risk factors contributing to hepatitis B include unsafe injections, low immunization coverage, low awareness, mother-to-child transmission, and limited health services. Further study is needed to better understand the prevalence and risk factors for hepatitis B amongst refugees in LMIC, to inform public health responses. Vulnerable populations such as refugees are an important group to consider in national and global efforts to eliminate hepatitis B.

Burden of infectious disease studies in Europe and the United Kingdom: a review of methodological design choices.

This systematic literature review aimed to provide an overview of the characteristics and methods used in studies applying the disability-adjusted life years (DALY) concept for infectious diseases within European Union (EU)/European Economic Area (EEA)/European Free Trade Association (EFTA) countries and the United Kingdom. Electronic databases and grey literature were searched for articles reporting the assessment of DALY and its components. We considered studies in which researchers performed DALY calculations using primary epidemiological data input sources. We screened 3053 studies of which 2948 were excluded and 105 studies met our inclusion criteria. Of these studies, 22 were multi-country and 83 were single-country studies, of which 46 were from the Netherlands. Food- and water-borne diseases were the most frequently studied infectious diseases. Between 2015 and 2022, the number of burden of infectious disease studies was 1.6 times higher compared to that published between 2000 and 2014. Almost all studies (97%) estimated DALYs based on the incidence- and pathogen-based approach and without social weighting functions; however, there was less methodological consensus with regards to the disability weights and life tables that were applied. The number of burden of infectious disease studies undertaken across Europe has increased over time. Development and use of guidelines will promote performing burden of infectious disease studies and facilitate comparability of the results.

A comprehensive study of the epidemiology of haematological malignancies in North Queensland.

BACKGROUND: There is an absence of clinically relevant epidemiological data in regional Australia pertaining to haematological malignancies. AIM: To determine the incidence and geographical variation of haematological malignancies in North Queensland using a clinically appropriate disease classification. METHODS: Retrospective, observational study of individual patient data records of all adults diagnosed with a haematological malignancy between 2005 and 2014 and residing within The Townsville Hospital Haematology catchment region. We report descriptive summaries, incidence rates and incidence-rate ratios of haematological malignancies by geographic regions. RESULTS: One thousand, five hundred and eighty-one haematological malignancies (69% lymphoid, 31% myeloid) were diagnosed over the 10-year study period. Descriptive data are presented for 58 major subtypes, as per the WHO diagnostic classification of tumours of haemopoietic and lymphoid tissues. The overall median age at diagnosis was 66 years with a male predominance (60%). We demonstrate a temporal increase in the incidence of haematological malignancies over the study period. We observed geographical variations in the age-standardised incidence rates per 100 000 ranging from 0.5 to 233.5. Our data suggest an increased incidence rate ratio for haematological malignancies in some postcodes within the Mackay area compared with other regions. CONCLUSION: The present study successfully reports on the incidence of haematological malignancies in regional Queensland using a clinically meaningful diagnostic classification system and identifies potential geographic hotspots. We advocate for such contemporary, comprehensive and clinically meaningful epidemiological data reporting of blood cancer diagnoses in wider Australia. Such an approach will have significant implications towards developing appropriate data-driven management strategies and public health responses for haematological malignancies.

A mixed-methods study of the awareness and functionality of sexual and reproductive health services among persons with disability in Ghana.

BACKGROUND: Persons with disabilities (PwDs) face barriers in accessing sexual and reproductive health (SRH) services due to lack of knowledge and awareness, stigma and discrimination, and inadequate service provision. This study aimed to examine the determinants of SRH knowledge and awareness among PwDs in Ghana, and to explore their perceptions of the functionality of SRH services. METHODS: A sequential explanatory mixed-methods study design was used to collect and analyse quantitative (n = 402) and qualitative (n = 37) data from PwDs in two districts in Ghana. Quantitative data were analysed using descriptive and inferential statistics, while qualitative data was analysed thematically. RESULTS: Most of the participants had high awareness of SRH (94.3%), sexually transmitted infections (STIs) (92.5%) and HIV/AIDS (97.0%). Employment status was positively associated with SRH awareness [aOR = 1.62; 95% CI = 1.02, 2.59]. Disability type was a significant predictor of STI [aOR = 2.02; 95% CI = 1.39, 2.94] and HIV/AIDS [aOR = 2.32; 95% CI = 1.21, 4.44] awareness, with the visually impaired having higher odds than the physically disabled. Age group was also a significant predictor of STI awareness, with older respondents having higher odds than younger ones [aOR = 1.76; CI = 1.01,3.05 for 30-39 years; aOR = 2.48; CI = 1.22, 5.05 for 40-49 years]. The qualitative findings revealed four main themes: conceptualisation of SRH, active engagement in SRH information seeking, tensions between knowledge and religious beliefs and perceived utility of SRH services. CONCLUSION: Despite the high levels of SRH knowledge and awareness among PwDs, there are significant gaps and challenges related to disability type, age group, misconceptions, beliefs, and service non-functionality that limit the utility of SRH services. The findings call for tailored education to reduce misconceptions and put in pragmatic steps to deliver quality SRH services and information to PwDs. Further research is needed to assess the sexual lives of PwDs and explore the perspectives of all relevant stakeholders, including service providers and policymakers on how to enhance SRH outcomes for PwDs in Ghana.

People with disability often encounter barriers in access sexual and reproductive health (SRH) services. These challenges arise from a lack of understanding and awareness about these services, stigma, and discrimination as well as unavailability of these services. This study sought to assess the extent of SRH knowledge and awareness among persons with disabilities (PwDs) in Ghana and to investigate their perceptions of the functionality of SRH services. To accomplish this, a study design that combined both quantitative and qualitative research methods was employed. The study collected and analysed data from 402 PwDs in two districts of Ghana. The quantitative data were subjected to descriptive and inferential statistical analyses, whereas the qualitative data, were thematically analysed. The findings indicated that a substantial number of participants demonstrated high awareness of SRH, including sexually transmitted infections (STIs) and HIV/AIDS. The participants' employment status was positively associated with their level of SRH awareness. Additionally, the type of disability played a significant role in predicting awareness of STIs and HIV/AIDS. Visually impaired individuals exhibited a greater likelihood of awareness compared to those with physical disabilities. Age also influenced STI awareness, with older respondents showing higher levels of awareness than their younger counterparts. Qualitative analyses unveiled four main themes: how SRH is conceptualised, the active seeking of SRH information, the tension between knowledge and religious beliefs, and the perceived usefulness of SRH services. The study concluded that PwDs have a high level of SRH knowledge and awareness. However, it identified gaps and challenges that stem from differences in disability type, age group, misconceptions, religious beliefs, and the effectiveness of the services provided. To address these issues, the study recommends tailored educational interventions to meet the unique needs and concerns of PwDs in relation to SRH. Furthermore, enhancing the quality and accessibility of SRH services for this population is suggested. The study underscores the need for further research on the sexual lives of PwDs and the views of stakeholders on how to enhance their SRH outcomes are needed.

Use of telemedicine for rheumatology practice in Queensland, Australia: experiences before and during the COVID-19 pandemic.

BACKGROUND: In Australia there is a shortage of rheumatologists potentially translating to poorer outcomes. A possible solution in this setting is telemedicine (TM). AIMS: To examine the utilisation and provider perceptions of TM in rheumatology in Queensland and explore the challenges faced when using TM before and during COVID-19. METHODS: A sequential mixed-methods study design was used. Rheumatologists completed a questionnaire on demographics, clinical practice, TM uptake, models of care and clinician perceptions of TM. The qualitative phase utilised purposeful sampling of active users of TM through in-depth semi-structured interviews. RESULTS: Thirty rheumatologists participated, with 76.7% identifying as active TM users. Use of TM was limited prior to COVID-19 with 80.9% examining less than five patients per week. Patient populations served by TM included capital city (53.3%), regional (63.3%) and rural/remote (23.3%). Most rheumatologists prescribed conventional or biological disease modifying agents (90% and 55%) through TM consultations. Barriers to TM use included low confidence in joint assessments, limited distribution of technology, access to administrative and peripheral clinical staff and lack of financial incentives. During the COVID-19 pandemic, a significant expansion of TM via telephone calls occurred and rheumatologists reported low confidence and satisfaction with this model. CONCLUSIONS: Familiarity with TM exists in this rheumatologist cohort; however, its use in routine practice is limited due to multiple barriers. The COVID-19 pandemic highlighted low confidence in telephone calls as a form of TM underlining the need for appropriate TM models of care for rheumatology practice.

Group B streptococcal bacteraemia: changing trends in a tropical region of Australia.

BACKGROUND: Group B streptococcus (GBS) is a recognised perinatal and neonatal pathogen. There are reports of increasing GBS sepsis globally outside this demographic. North Queensland is part of tropical Australia, with a relatively high proportion of Indigenous Australians. AIMS: To analyse the epidemiology of GBS bacteraemia and explore associated risk factors. METHODS: This was a 10-year retrospective review of GBS bacteraemia in a tertiary facility in North Queensland, between 2010 and February 2020. Data variables collected included: demographics, risk factors, clinical source and outcomes. Multivariable logistic regression was performed to examine the association of indigenous status and other relevant clinical factors with mortality from GBS bacteraemia at 3 months. RESULTS: Of the 164 total cases, 123 were not pregnancy related. The annual rate of GBS bacteraemia for the indigenous population was 12.48 per 100 000 and 4.84 per 100 000 for the non-indigenous population. Indigenous patients were more likely to have diabetes and chronic kidney disease compared with the non-indigenous patients. Males (adjusted odds ratio (AOR) = 4.34; 95% CI 1.14-16.56; P = 0.031) and immunosuppressed patients (AOR = 11.49; 95% CI 2.73-48.42; P < 0.001) were more likely to experience mortality at 3 months from GBS bacteraemia even after adjusting for other risk factors respectively. CONCLUSION: GBS bacteraemia is deviating from being primarily a neonatal disease. While the indigenous population of North Queensland are disproportionately affected, the demographics affected differ. GBS appears to target the older non-indigenous patients with greater comorbidities. In the non-indigenous population, invasive GBS disease is an emerging issue. Three-month mortality appears to be increased in males and the immunosuppressed.

The practice of integrated healthcare and the experiences of people in Ghana's Ashanti region.

BACKGROUND: The Ghanaian government has implemented interventions that integrate traditional medicine (TM) into its national health system in response to the high prevalence of TM use. However, empirical evidence of the experiences of service users and the practice of integrated health in Ghana is scanty. Therefore, this study explored the experiences of people with TM integration into the formal health system in Ashanti region using an adapted TM integration framework. METHODS: A sequential explanatory mixed methods study design comprising survey administration and in-depth interviews for data collection was utilised to address the research objective. Framework analysis was used in analysing the qualitative data and for triangulation of results. RESULTS: Participants were aware of licensing and training of TM practitioners in a science-based university in Ghana. However, knowledge of the existence of TM units in selected hospitals in the region was minimal. Integration knowledge was largely influenced by sex, marital status, household size and residential status, where males and urban dwellers were more familiar with the process than females and rural dwellers. Low patronage of integrated health services in the region was attributable to weak cross referrals. However, service users who had engaged with the integrated system recounted a satisfactory outcome. CONCLUSION: Service users' unfamiliarity with the presence of integrated facilities in Ghana could be an impediment to the practice of integrated healthcare. Sensitisation of the public about the practice of an integrated system could refine the Ghanaian integrated system. Regular evaluation of patient satisfaction and outcome measures might also serve as an effective strategy for improving health services delivery since evaluation is becoming an important component of health service design and implementation. There is the need for future studies to focus on exploring the perceptions and experiences of health practitioners and hospital administrators regarding the practice of integrated health in Ghana.

A Comparison of Clinical Characteristics and Outcomes Between Indigenous and Non-Indigenous Patients Presenting to Townsville Hospital Emergency Department With Chest Pain.

BACKGROUND: Indigenous Australians have a high rate of ischaemic heart disease (IHD). There is a paucity of local data for North Queensland regarding the clinical characteristics of Indigenous people who present to the emergency department (ED) with chest pain. The aim of the study is to compare the cardiovascular risk factors, social characteristics, and the clinical outcomes between Indigenous and non-Indigenous patients who presented with cardiac-related chest pain. METHODS: This is a retrospective single-centre audit. The data was collected through chart reviews of chest pain presentations to the Townsville University Hospital Emergency Department, Queensland, Australia, from January to December 2017. We categorised the patients into Indigenous and non-Indigenous groups and compared their cardiac risk factors and social characteristics. We further classified the patients into three diagnosis groups and we measured the clinical outcomes in the patients with a diagnosis of cardiac-related chest pain. We used a data linkage to the Registry of Births, Deaths and Marriages for the death outcomes. A multivariable analysis was done to determine the risk of major adverse cardiac event (MACE) for Indigenous vs non-Indigenous patients. RESULTS: Indigenous patients were over-represented making up 19.1% of the total cohort (compared with 11.1% of the North Queensland Indigenous population) and presented at a younger age (median age: 45 vs 52, p<0.005). Traditional cardiovascular risk factors were significantly higher in Indigenous patients. The incidence of discharge against medical advice was also higher (6.5% vs 2.7%, p<0.005). There was an underutilisation of the local chest pain pathway amongst the Indigenous group (35.8% vs 44.7%, p<0.005). In patients with a diagnosis of cardiac-related chest pain, the rate of receiving invasive coronary angiogram procedures was similar in both cohorts (44.5% vs 43.7%, p=0.836). With regards to outcomes, Indigenous patients suffered from acute coronary syndrome (ACS) at a younger median age (51 vs 64, p<0.005) and were more likely to have severe three vessel disease (17% vs 6%, p<0.005) leading to coronary bypass graft surgery (CABG) (19% vs 6%, p<0.005). When adjusted for age, gender, and comorbidities, Indigenous patients were more likely to have MACE within 1 year of their chest pain presentation, compared with non-Indigenous patients with the same diagnosis (adjusted odds ration [AOR]=2.0, 95% CI [1.1, 3.8], p=0.03). CONCLUSION: In our study, Indigenous patients carried a heavier burden of cardiovascular risk factors, presented at a younger age, with more severe coronary disease and had a higher rate of CABG. We found an underutilisation of the local chest pain protocol amongst the Indigenous cohort, which suggests a need to improve support structures in the ED. In our multivariable analysis, Indigenous patients suffered from a significantly higher MACE compared to non-Indigenous patients which indicates that more collaborative efforts are needed to improve the cardiovascular health of local Aboriginal and Torres Strait Islander people.

Association Between Indigenous Status and Severity of Coronary Artery Disease: A Comparison of Coronary Angiogram Findings in Patients With Chest Pain Presenting to a Regional Hospital Emergency Department.

BACKGROUND: Coronary artery disease (CAD) remains the leading cause of death amongst Indigenous Australians accounting for 12.1% of all deaths in this population. However, there is little evidence to suggest that Indigenous status is an independent risk factor for the development of coronary artery disease. This study assessed the association between Indigenous status and the severity of CAD in patients presenting with chest pain at a regional hospital emergency department. METHODS: This was a retrospective single-centre audit over 12 months from January to December 2017. Charts were reviewed for both Indigenous and non-Indigenous patients 18 years and older who presented with chest pain and subsequently underwent an invasive coronary angiogram. Multivariable logistic regression was performed to examine the association of Indigenous status with the severity of CAD. RESULTS: Indigenous patients are 2.7 times more likely to experience significant CAD compared to non-Indigenous patients (Adjusted odds ratio [AOR]=2.73, 95% CI [1.38, 5.39], p≤0.001) even after adjusting for other risk factors. Those aged 65 years and older are more prone to significant CAD (AOR=2.96, 95% CI [1.12, 7.78], p=0.03), while women were less likely to have significant CAD compared to men, (AOR=0.46, 95% CI [0.27, 0.78], p<0.01). CONCLUSION: In this study cohort, our analysis indicates that there is a strong association between Indigenous status and significant coronary artery disease, independent of the increased burden of traditional cardiovascular risk factors among Indigenous Australians.

Antimicrobial stewardship in diabetic ketoacidosis: a single-centre experience.

BACKGROUND: Diabetic ketoacidosis (DKA) is a common and serious complication arising predominantly in patients with type 1 diabetes mellitus. International data demonstrate that infection is one of the most common precipitating causes of DKA. Currently there are limited data regarding the role of antimicrobial stewardship (AMS) in this setting. AIM: To provide epidemiologic data regarding infections precipitating DKA, microbiological aetiology and antimicrobial prescribing practices in order to inform AMS interventions. METHODS: Retrospective chart review of all type 1 diabetes mellitus DKA presentations from May 2015 to June 2018. RESULTS: In total, 249 DKA presentations occurred in 111 patients. Suspected infection accounted for 100/249 (40%) presentations, and only 36/249 (14.5%) were proven or probable infections. Skin and soft tissue infection was the most common (9/36, 25%), followed by urinary tract infection (8/36, 22%) and respiratory tract infection (7/36, 19%). A pathogen was identified in 24/100 presumed infections and included Staphylococcus aureus (24, 46%), Klebsiella pneumoniae (4/24, 17%) and Escherichia coli (3/24, 13%). No viral pathogens were identified. Of 80 empirical antimicrobial prescriptions, 75% were inappropriate based on guideline management of the documented suspected infection. Single agent ceftriaxone was appropriately prescribed in 7/23 (30%) cases, and was most frequently prescribed overall 23/80 (29%). CONCLUSION: This study demonstrates a lower incidence of infection compared to most previous publications, and suggests that infection-precipitated DKA may be over reported. Furthermore, our findings provide support for the role of AMS in the management of DKA.

Effectiveness of Integrated Health Systems in Africa: A Systematic Review.

Background and objective: Traditional medicine (TM) was integrated into health systems in Africa due to its importance within the health delivery setup in fostering increased health care accessibility through safe practices. However, the quality of integrated health systems in Africa has not been assessed since its implementation. The objective of this paper was to extensively and systematically review the effectiveness of integrated health systems in Africa. Materials and Methods: A systematic literature search was conducted from October, 2019 to March, 2020 using Ovid Medline, Scopus, Emcare, Web of Science, Cumulative Index to Nursing and Allied Health (CINAHL), and Google Scholar, in order to retrieve original articles evaluating the integration of TM into health systems in Africa. A quality assessment of relevant articles was also carried out using the Quality Assessment Tool for Studies with Diverse Designs (QATDSS) critical appraisal tool. Results: The results indicated that the formulation and execution of health policies were the main measures taken to integrate TM into health systems in Africa. The review also highlighted relatively low levels of awareness, usage, satisfaction, and acceptance of integrated health systems among the populace. Knowledge about the existence of an integrated system varied among study participants, while satisfaction and acceptance were low among orthodox medicine practitioners. Health service users' satisfaction and acceptance of the practice of an integrated health system were high in the countries assessed. Conclusion: The review concluded that existing health policies in Africa are not working, so the integration of TM has not been successful. It is critical to uncover the barriers in the health system by exploring the perceptions and experiences of stakeholders, in order to develop solutions for better integration of the two health systems.

Non-urgent paediatric emergency department presentation: A systematic review.

There has been an increase in the use of the emergency department (ED) for non-urgent presentations. The aim of this systematic review was to identify the proportion, criteria and predictors of non-urgent ED presentations in paediatric populations. A search of multiple databases was conducted for articles published from inception of the databases to 20 August 2018, which reported the proportion, criteria and predictors of non-urgent ED presentation in paediatric populations. Thirty-one articles met the inclusion criteria. The mean proportion of non-urgent paediatric ED presentations was 41.06 ± 15.16%. There appears to be a weak association between predisposing, enabling and needs factors and non-urgent ED use in paediatric populations. The findings of this review suggest that non-urgent ED use in paediatric populations is high. However, non-urgent ED use and the reasons for the visits in paediatric populations remain understudied.

The role of anticholinergic medication in the prevention of bradycardia during laparoscopic gynaecological surgery.

Bradycardia and cardiac arrest are recognised complications of laparoscopic gynaecological surgery. Anticholinergic agents are indicated in the treatment of perioperative bradyarrhythmia; however, their role in the prevention of bradycardia as a result of insufflation of the peritoneum is less well defined. This article systematically reviewed the literature with respect to the role of anticholinergic agents in the prevention of clinically significant bradyarrhythmia during laparoscopic gynaecological surgery. Eight studies were included for review following an extensive database search. This review highlights the paucity of evidence supporting the prophylactic use of anticholinergic agents in preventing clinically significant bradycardia in women undergoing laparoscopic gynaecological surgery.

Epidemiology, Risk Factors and Measures for Preventing Drowning in Africa: A Systematic Review.

: Background: Drowning is a leading cause of unintentional injury related mortality worldwide, and accounts for roughly 320,000 deaths yearly. Over 90% of these deaths occur in low- and middle-income countries with inadequate prevention measures. The highest rates of drowning are observed in Africa. The aim of this review is to describe the epidemiology of drowning and identify the risk factors and strategies for prevention of drowning in Africa. Methods: A review of multiple databases (MEDLINE, CINAHL, PsycINFO, Scopus and Emcare) was conducted from inception of the databases to the 1st of April 2019 to identify studies investigating drowning in Africa. The preferred reporting items for systematic review and meta-analysis (PRISMA) was utilised. Results: Forty-two articles from 15 countries were included. Twelve articles explored drowning, while in 30 articles, drowning was reported as part of a wider study. The data sources were coronial, central registry, hospital record, sea rescue and self-generated data. Measures used to describe drowning were proportions and rates. There was a huge variation in the proportion and incidence rate of drowning reported by the studies included in the review. The potential risk factors for drowning included young age, male gender, ethnicity, alcohol, access to bodies of water, age and carrying capacity of the boat, weather and summer season. No study evaluated prevention strategies, however, strategies proposed were education, increased supervision and community awareness. Conclusions: There is a need to address the high rate of drowning in Africa. Good epidemiological studies across all African countries are needed to describe the patterns of drowning and understand risk factors. Further research is needed to investigate the risk factors and to evaluate prevention strategies.

Predicting the Outcomes of New Short-Course Regimens for Multidrug-Resistant Tuberculosis Using Intrahost and Pharmacokinetic-Pharmacodynamic Modeling.

Short-course regimens for multidrug-resistant tuberculosis (MDR-TB) are urgently needed. Limited data suggest that the new drug bedaquiline (BDQ) may have the potential to shorten MDR-TB treatment to less than 6 months when used in conjunction with standard anti-TB drugs. However, the feasibility of BDQ in shortening MDR-TB treatment duration remains to be established. Mathematical modeling provides a platform to investigate different treatment regimens and predict their efficacy. We developed a mathematical model to capture the immune response to TB inside a human host environment. This model was then combined with a pharmacokinetic-pharmacodynamic model to simulate various short-course BDQ-containing regimens. Our modeling suggests that BDQ could reduce MDR-TB treatment duration to just 18 weeks (4 months) while still maintaining a very high treatment success rate (100% for daily BDQ for 2 weeks, or 95% for daily BDQ for 1 week during the intensive phase). The estimated time to bacterial clearance of these regimens ranges from 27 to 33 days. Our findings provide the justification for empirical evaluation of short-course BDQ-containing regimens. If short-course BDQ-containing regimens are found to improve outcomes, then we anticipate clear cost savings and a subsequent improvement in the efficiency of national TB programs.

Cryptococcal infections over a 15 year period at a tertiary facility & impact of guideline management.

Cryptococcosis is an invasive fungal infection caused primarily by Cryptococcus neoformans and Cryptococcus gattii species, presenting predominantly as meningoencephalitis. The aim of this study is to assess all cryptococcal infections managed at our facility from 2001 to 2015 to determine incidence, risk factors, and comparison of outcomes prior to and following introduction of the 2010 Infectious Disease Society of America (IDSA) guidelines. Retrospective analysis of all patients diagnosed and treated for cryptococcal infection occurring between January 2001 and December 2015. Of 102 patients diagnosed with cryptococcal infection, 97 were eligible for study inclusion. There appears to be an overall increased incidence of cryptococcosis in both transplant and non-transplant cohorts with a peak in 2015 of 6 transplant and 13 non-transplant cases. In the meningitis cohort, 38/52 (73%) of identified isolates were C. neoformans, and 14/52 (27%) were C. gattii. Notably, 14/14 (100%) of C. gattii isolates were associated with meningitis, as compared to only 38/64 (59%) C. neoformans associated with meningitis (P: .003). It appears that patients presenting with cough are less likely to have meningitis, 17/27 (63%), (P: .005). When stratifying for culture positive meningitis lumbar puncture opening pressure, the median in the culture positive cohort was 31.5 cm H2 O compared with 15.5 cm H2 O (P: .036).Multiple admissions were required prior to diagnosis in the majority of cases with only 18/72 (25%) diagnosed on 1st presentation. Postguideline mortality has improved from 15% to 6.1% (P: .046). Cryptococcal infection remains relatively uncommon, but there appears to be an increasing trend in incidence. Overall mortality is relatively low and has improved since introduction of the 2010 IDSA guidelines.

Socio-economic composition of low-acuity paediatric presentation at a regional hospital emergency department.

AIM: Despite increasing rates of emergency department (ED) utilisation, little is known about low-acuity presentations in children ≤5 years. The aims of the study were to estimate the proportion and cost of low-acuity presentations in children ≤5 years presenting to the ED and to determine the relative effect of socio-economic status (SES) on paediatric low-acuity presentations at the ED. METHODS: This is a retrospective observational study of children ≤5 years presenting to the Cairns Hospital ED over 4 years. A multivariate logistic regression model was used to assess the association between SES and low-acuity presentations. Cost of low-acuity presentations was calculated based on triage score and admission status, using costs obtained from the National Hospital Cost Data Collection. RESULTS: A total of 23 086 children were included in the study, of whom 56.7% were male (mean age = 1.85 ± 1.63 years). Approximately one-third of ED visits were low-acuity presentations (32.4%), and low-acuity presentations increased progressively with SES. In multivariate analysis, children from families with very high SES were twice as likely to have a low-acuity presentation (odds ratio 2.17; 95% confidence interval, 1.66-2.85). Low-acuity ED presentations cost the health-care system in excess of A$895 000-A$1 110 000 per year. CONCLUSIONS: These findings demonstrate that a significant proportion of paediatric ED visits are of low acuity and that these visits yield a substantial cost to the health system. Further research is required regarding care givers' rationale and potentially other reasons underlying these low-acuity ED presentations.
