Comparison of Adjustment or Adaptation to the Formation of a Temporary Versus a Permanent Ostomy: A Systematic Review.

PURPOSE: The aim of this systematic review was to review evidence on adjustment or adaptation to an ostomy in persons with a temporary versus permanent ostomy. METHOD: Systematic review. SEARCH STRATEGY: We comprehensively searched the following bibliographic databases: MEDLINE (Ovid SP), EMBASE (Ovid SP), PsycINFO, CINAHL, Joanna Briggs, Scopus, and EThOS and ProQuest dissertations from inception to July 21, 2021. We located 570 studies. Data were extracted into Covidence, and the risk of bias was assessed using the Newcastle-Ottawa Scale and the Joanna Briggs tool. FINDINGS: Thirty-one studies met inclusion criteria and were included; only 2 assessed adjustment using a validated adjustment tool (Ostomy Adjustment Inventory, OAI-23). One found better adjustment in those with a permanent ostomy at 6 months; the second did not formally test for statistically significant differences between groups. Other included studies assessed aspects of adjustment such as health-related quality of life and psychological symptoms. Findings differed between studies; the majority of studies were deemed at a high risk of bias. CONCLUSIONS: The quality of evidence among studies evaluating adjustment to an ostomy in permanent versus temporary stomas was poor; the majority did not measure adjustment using a validated adjustment instrument. Therefore, differences in the ways those with a temporary ostomy or permanent ostomy adjust or adapt remain largely unknown. IMPLICATIONS: Further high-quality studies are needed that compare adjustment to a temporary or permanent ostomy using a validated instrument. An understanding of differences in adjustment in those with a temporary and permanent ostomy is important for planning how health care services can be better tailored to meet the needs of ostomy patients beyond the initial postoperative period of recovery.

Joint predictability of physical frailty/pre-frailty and subjective memory complaints on mortality risk among cognitively unimpaired older adults.

The aim of the present study was to investigate how frailty/pre-frailty in combination with subjective memory complaints predicts all-cause mortality in community dwelling cognitively unimpaired older adults. There were 1904 community-dwelling cognitively unimpaired persons aged 65 years or older who participated in the 2013 Taiwan National Health Interview Survey with a 5-year follow-up. Frailty was determined based on the fatigue, resistance, ambulation, illness, and loss of weight (FRAIL) scale. Two questions ("Do you have difficulties with your memory or attention?" and "Do you have difficulties with your memory only or attention only or both?") were used to screen for subjective memory complaints (SMC). In this study, 11.9% of participants had both frailty/pre-frailty and SMC. A total of 239 deaths were recorded after 9009.5 person-years of follow-up. After adjustment for other factors, compared with participants who were physically robust with no SMC, participants who reported either SMC alone (HR = 0.88, 95% CI = 0.60-1.27) or were frail/pre-frail alone (HR = 1.32, 95% CI = 0.90-1.92) had no significantly increased mortality risk. However, coexisting frailty/pre-frailty and SMC was associated with a significantly increased hazard ratio for mortality of 1.48 (95% CI = [1.02-2.16]). Our results highlight the high prevalence of co-occurring frailty/pre-frailty and SMC and that this co-occurrence is associated with an increased risk of mortality among cognitively unimpaired older adults.

Rural-to-urban migration, socio-economic status and cardiovascular diseases risk factors among Bangladeshi adults: A nationwide population based survey.

Background: Rural-to-urban migration is one of the key drivers of urbanization in Bangladesh and may impact on cardiovascular diseases (CVD) risk due to lifestyle changes. This study examined whether CVD risk factors were associated with migration to and duration of urban life, considering socio-economic indicators. Methods: A total of 27,792 participants (18-59 years) from the 2006 Bangladesh cross-sectional Urban Health Survey were included in the analyses of whom 14,167 (M: 7,278; W: 6,889) were non-migrant urban residents and 13,625 (M: 6,413; W: 7,212) were rural-to-urban migrants. Gender-specific prevalence of CVD risk factors were estimated for urban and migrant groups. Multivariate logistic regression models were used to test the association between each CVD risk by education and wealth within each study group and their possible effect modification. An analysis on the rural-to-urban migrant subgroup only was conducted to examine the association between each CVD risk factor and length of urban stay adjusted for demographic and socio-economic indicators. Results: Compared to urban residents, migrants had significantly lower prevalence of overweight/obesity for both genders. Hypertension was higher among urban women while alcohol/illicit drug use was higher among urban men. Mental health disorders were higher among migrants than urban residents for both genders and no difference were noted for diabetes or cigarette smoking prevalence. In both study groups and genders, the risk of overweight/obesity, hypertension and diabetes increased with increasing education and wealth whereas for mental health disorders, alcohol/illicit drug use, cigarette and bidi smoking the reverse was found. Differences in BMI between migrant and urban women were attenuated with increased education levels (p = 0.014 for interaction). Consistent increasing pattern of risk was observed with longer duration of urban stay; in migrant men for obesity (OR = 1.67), smoking (OR = 1.67) and alcohol/illicit drug use (OR = 2.86), and for obesity and mental health disorder among migrant women. Conclusions: Migrants had high proportion of CVD risk factors which were influenced by education, wealth and duration of urban stay.

Prevalence of visual impairment in older people living with dementia and its impact: a scoping review.

BACKGROUND AND OBJECTIVES: Visual impairment (VI) and dementia both increase with age, and it is likely that many older people are living with both conditions. This scoping review aims to investigate the prevalence and types of VI among older people living with dementia, and the impact of VI on older people living with dementia and their caregivers. METHODS: This scoping review used Arksey and O'Malley's methodological framework. Studies in any setting involving people living with dementia and some assessment of either VI, eye diseases causing VI or the impact of VI were included. RESULTS: Thirty-six studies were included. Thirty-one studies reported the prevalence of VI in older people living with dementia, while ten studies reported on impacts of VI on people living with dementia. Only one study reported on impacts on caregivers. The prevalence of VI or specific eye diseases among older people living with dementia ranged from 0.2 to 74%. The impacts of VI on older people living with dementia included increased use of hospital services, increased disability and dependency, reduced social engagement, negative emotions, increased abnormal behaviours, loss of hobbies, difficulty in using visual aids or memory aids, and greater Neuropsychiatric Inventory symptoms. And the impacts on caregivers included increased conflict and physical exhaustion. CONCLUSION: VI is common in older people living with dementia and is associated with negative impacts on those with dementia and their caregivers. However, heterogeneity between studies in terms of setting and method for assessing and defining VI make it difficult to compare findings among studies. Further research is needed, particularly assessing the impact on caregivers.

Considering potential benefits, as well as harms, from the COVID-19 disruption to cancer screening and other healthcare services.

Since 2020, hundreds of thousands of more deaths than expected have been observed across the globe. Amid the coronavirus 2019 (COVID-19) pandemic, current research priorities are to control the spread of infection and minimise loss of life. However, there may be future opportunities to learn from the pandemic to build a better healthcare system that delivers maximum health benefits with minimum harm. So far, much research has focused on foregone benefits of healthcare services such as cancer screening during the pandemic. A more balanced approach is to recognise that all healthcare services have potential harms as well as benefits. In this way, we may be able to use pandemic 'natural experiments' to identify cases where a reduction in a healthcare service has not been harmful to the population and some instances where this may have even been beneficial.

Oral health-related quality of life of older Australian men.

OBJECTIVES: The aims of this study were to assess oral health-related quality of life (OHRQoL) in a cohort of older Australian men and explore the association between their general health conditions, socio-demographic factors and OHRQoL. METHODS: The Concord Health and Ageing in Men Project (CHAMP) is a cohort study of the health of a representative sample of Australian men, initiated in 2005-2006 with an initial sample of 1705 men 70 years or over. Participants completed a self-administered health and socio-demographic questionnaire and attended an interview and clinical assessment at baseline and each of three follow-up assessments. Information on oral health and responses to the Oral Health Impact Profile (OHIP-14) were collected in the 4th follow-up in which 778 men completed the OHIP-14 questionnaire and 614 men had a dental assessment. The prevalence of oral health impact was defined as a response of fairly often or very often to one or more of the OHIP-14 questions. Mean OHIP-14 scores were calculated for the 14 questions and used as the dependent variable in the regression analyses. Zero-inflated Poisson regression was used to estimate prevalence rate ratios (PRR). RESULTS: Only 10% of men presented oral health impacts. In multivariate regression modelling, being born in Italy/Greece (PRR: 2.16, 95% CI: 1.93-2.42) or in other countries (PRR: 2.12, 95% CI: 1.89-2.38), having poor self-rated general health (PRR: 1.38, 95% CI: 1.24-1.53), having poor mental wellbeing (PRR: 1.14, 95% CI: 1.04-1.24), having ≥6 depressive symptoms (PRR: 1.18, 95% CI: 1.05-1.32), being a current smoker (PRR: 1.34, 95% CI: 1.06-1.70) and having more decayed tooth surfaces (PRR:1.01, 95% CI: 1.00-1.02) were associated with higher impact scores. CONCLUSIONS: Overall, older Australian men exhibit good oral health-related quality of life. The inter-relationship between perceptions of general health and well-being, health and oral health variables and social background supports policy objectives of closer integration of general health and oral health services for older Australian men.

Diagnostic accuracy of linked administrative data for dementia diagnosis in community-dwelling older men in Australia.

BACKGROUND: Routinely collected health administrative data can be used to estimate the prevalence or incidence of dementia at a population level but can be inaccurate. This study aimed to examine the accuracy of hospital and death data for diagnosing dementia compared with a clinical diagnosis in community dwelling older men in Australia. METHODS: We performed a retrospective analysis of the Concord Health and Ageing in Men Project (CHAMP) in Sydney, Australia. Of the 1705 men aged ≥70 years in the CHAMP study, 1400 had available linked administrative data records from 1 year prior to 1 year post the date of clinical dementia diagnosis. The primary outcome was the accuracy of dementia diagnosis using linked administrative data records compared to clinical dementia diagnosis. The linked data diagnosis was based on hospital and death records for the 1 year pre and post the clinical diagnosis. Clinical dementia diagnosis was a two-stage process with initial screening, followed by clinical assessment for those meeting a validated cut-off. A final clinical diagnosis of dementia based on the Diagnostic and Statistical Manual of Mental Disorders (4th edition) criteria was reached by a consensus panel. RESULTS: Administrative data identified 28 participants as having dementia, compared to 88 identified through clinical assessment. Administrative data had a sensitivity of 20% (95% CI: 13-30%, 18/88), specificity of 99% (95% CI: 99-100%, 1301/1312), positive predictive value (PPV) of 62% (95% CI: 44-77%), negative predictive value of 95% (95% CI: 94-95%), positive likelihood ratio of 24.4 (95% CI: 11.9-50.0) and negative likelihood ratio of 0.80 (0.72-0.89). CONCLUSIONS: Administrative hospital and death data has limited accuracy for dementia diagnosis with poor sensitivity and PPV. The prevalence of dementia is likely underestimated using hospital and deaths data.

Does physical activity protect older persons with frailty and cognitive impairment from excess all-cause mortality?

OBJECTIVES: The main aim of this study was to examine how physical activity in combination with physical frailty and cognitive impairment affects risk of mortality in older adults. STUDY DESIGN: A national sample of community-dwelling Taiwanese aged 65 years or older (n=2678) was followed for 5 years. MAIN OUTCOME MEASURES: Frailty was determined based on the Fatigue, Resistance, Ambulation, Illness, and Loss of weight (FRAIL) scale. The Mini-Mental State Examination was used to assess cognitive impairment. Information on self-reported physical activity was collected at baseline. The study cohort was followed until the date of death or the end of the study period (31 December 2018). Deaths were confirmed by the computerized data files of the National Register of Deaths. RESULTS: A total of 417 deaths were recorded after 12415.2 person-years of follow-up. After adjustment for other factors, compared with active participants who were physically robust with normal cognition, inactive participants who were with either frail/pre-frail or cognitively impaired had hazard ratios for mortality of 2.65 (95% CI=[1.88-3.74]) and 3.09 (95% CI=[2.08-4.59]), respectively. Inactive participants with coexisting frailty/pre-frailty and cognitive impairment had the highest hazard ratio for mortality of 3.85 (95% CI=[2.73-5.45]). Being active was associated with a mortality reduction of 31%, 38%, and 42% in physically robust participants with normal cognition, those who were frail/pre-frail only, and those with cognitive impairment only, respectively. CONCLUSIONS: Having a physically active life style has beneficial effects on survival in older persons with either frailty/pre-frailty or cognitive impairment.

Representation of racial and ethnic minority groups in cohort studies evaluating risk factors for dementia: protocol for a scoping review.

INTRODUCTION: Available evidence suggests that some racial/ethnic minority populations may be disproportionately burdened by dementia. Cohort studies are an important tool for defining and understanding the causes behind these racial and ethnic inequalities. However, ethnic minority populations may be more likely to be excluded from such research. Therefore, the aim of this study is to systematically investigate and quantify racial and ethnic minority representation in dementia risk factor research. METHODS AND ANALYSIS: The elements of this protocol have been designed in accordance with the relevant sections of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols which are specifically applicable to scoping review protocols. We will include population-based cohort studies looking at risk factors for dementia incidence in our review and assess the representation of racial and ethnic minority populations in these studies. We will use multiple strategies to identify relevant studies, including a systematic search of the following electronic databases: MEDLINE (Ovid SP), Embase (Ovid SP) and Scopus. Two review authors will independently perform title and abstract screening, full-text screening and data extraction. Included cohort studies will be evaluated using a comprehensive framework to assess racial/ethnic minority representation. Logistic regression will also be performed to describe associations between cohort study characteristics and outcomes related to racial and ethnic minority representation. ETHICS AND DISSEMINATION: Formal ethical approval is not required to conduct this review as no primary data are to be collected. The final results of this scoping review will be disseminated through publication in peer-reviewed journals and conference presentations.

Diet quality in an ethnically diverse population of older men in Australia.

BACKGROUND/OBJECTIVES: To compare the Australian Dietary Guideline Index (DGI-2013) and the Pyramid-based Mediterranean Diet Score (pyrMDS) as measures of diet quality in an ethnically diverse group of older men. SUBJECTS/METHODS: Seven hundred and ninety-four older men aged ≥75 participated in wave 3 (2012-2013) of the Concord Health and Ageing in Men Project. Dietary intake was assessed using a validated diet history questionnaire. Ethnicity was based on self-reported country of birth and categorised as Australian-born (418 men), Italian or Greek migrants (188), and other migrants (188). Incident cardiovascular outcomes until March 2018 were measured using the composite of major adverse cardiovascular events (MACE), which comprises all-cause mortality, acute myocardial infarction, congestive cardiac failure, coronary revascularisation and/or ischaemic stroke. Ability to predict incident cardiovascular outcomes and all-cause mortality were compared between standardised DGI-2013 pyrMDS scores by comparison of hazard ratios, discrimination (Harrell's C-statistic) and calibration (calibration plots). RESULTS: Italian and Greek migrant men had significantly lower DGI-2013 scores (91.7 vs. 93.9; p = 0.01) but significantly higher pyrMDS scores (8.8 vs. 8.2; p < 0.0001) than Australian-born men. In the whole sample (794 men), the pyrMDS was a better predictor of both MACE (age-adjusted HR = 0.84; 95% CI = 0.75-0.94 vs. HR = 0.92; 95% CI = 0.82-1.03 for DGI-2013) and all-cause mortality (age-adjusted HR = 0.69; 95% CI = 0.60-0.80 vs. HR = 0.86; 95% CI = 0.74-0.99). The pyrMDS also demonstrated superior discrimination for predicting all-cause mortality and superior calibration for MACE and all-cause mortality. CONCLUSIONS: The DGI-2013 appears to underestimate diet quality in older Italian and Greek migrant men. The pyrMDS appears superior to the DGI-2013 for prediction of incident cardiovascular disease and mortality regardless of ethnic background.

Using Lean Six Sigma techniques to improve efficiency in outpatient ophthalmology clinics.

BACKGROUND: Increasing patient numbers, complexity of patient management, and healthcare resource limitations have resulted in prolonged patient wait times, decreased quality of service, and decreased patient satisfaction in many outpatient services worldwide. This study investigated the impact of Lean Six Sigma, a service improvement methodology originally from manufacturing, in reducing patient wait times and increasing service capacity in a publicly-funded, tertiary referral outpatient ophthalmology clinic. METHODS: This quality improvement study compared results from two five-months audits of operational data pre- and post-implementation of Lean Six Sigma. A baseline audit was conducted to determine duration and variability of patient in-clinic time and number of patients seen per clinic session. Staff interviews and a time-in-motion study were conducted to identify issues reducing clinic service efficiency. Solutions were developed to address these root causes including: clinic schedule amendments, creation of dedicated postoperative clinics, and clear documentation templates. A post-implementation audit was conducted, and the results compared with baseline audit data. Significant differences in patient in-clinic time pre- and post-solution implementation were assessed using Mann-Whitney test. Differences in variability of patient in-clinic times were assessed using Brown-Forsythe test. Differences in numbers of patients seen per clinic session were assessed using Student's t-test. RESULTS: During the baseline audit period, 19.4 patients were seen per 240-minute clinic session. Median patient in-clinic time was 131 minutes with an interquartile range of 133 minutes (84-217 minutes, quartile 1- quartile 3). Targeted low/negligible cost solutions were implemented to reduce in-clinic times. During the post-implementation audit period, the number of patients seen per session increased 9% to 21.1 (p = 0.016). There was significant reduction in duration (p < 0.001) and variability (p < 0.001) of patient in-clinic time (median 107 minutes, interquartile range 91 minutes [71-162 minutes]). CONCLUSIONS: Lean Six Sigma techniques may be used to reduce duration and variability of patient in-clinic time and increase service capacity in outpatient ophthalmology clinics without additional resource input.

Why clinicians overtest: development of a thematic framework.

BACKGROUND: Medical tests provide important information to guide clinical management. Overtesting, however, may cause harm to patients and the healthcare system, including through misdiagnosis, false positives, false negatives and overdiagnosis. Clinicians are ultimately responsible for test requests, and are therefore ideally positioned to prevent overtesting and its unintended consequences. Through this narrative literature review and workshop discussion with experts at the Preventing Overdiagnosis Conference (Sydney, 2019), we aimed to identify and establish a thematic framework of factors that influence clinicians to request non-recommended and unnecessary tests. METHODS: Articles exploring factors affecting clinician test ordering behaviour were identified through a systematic search of MedLine in April 2019, forward and backward citation searches and content experts. Two authors screened abstract titles and abstracts, and two authors screened full text for inclusion. Identified factors were categorised into a preliminary framework which was subsequently presented at the PODC for iterative development. RESULTS: The MedLine search yielded 542 articles; 55 were included. Another 10 articles identified by forward-backward citation and content experts were included, resulting in 65 articles in total. Following small group discussion with workshop participants, a revised thematic framework of factors was developed: "Intrapersonal" - fear of malpractice and litigation; clinician knowledge and understanding; intolerance of uncertainty and risk aversion; cognitive biases and experiences; sense of medical obligation "Interpersonal" - pressure from patients and doctor-patient relationship; pressure from colleagues and medical culture; "Environment/context" - guidelines, protocols and policies; financial incentives and ownership of tests; time constraints, physical vulnerabilities and language barriers; availability and ease of access to tests; pre-emptive testing to facilitate subsequent care; contemporary medical practice and new technology CONCLUSION: This thematic framework may raise awareness of overtesting and prompt clinicians to change their test request behaviour. The development of a scale to assess clinician knowledge, attitudes and practices is planned to allow evaluation of clinician-targeted interventions to reduce overtesting.

Associations between oral health and depressive symptoms: Findings from the Concord Health and Ageing in Men Project.

OBJECTIVE: To investigate whether poorer oral health, tooth loss and lower usage of dental services are associated with depressive symptoms in older Australian men. METHODS: Cross-sectional study of data collected from participants of the Concord Health and Ageing in Men Project. Depressive symptoms were evaluated by the Geriatric Depression Scale. Chewing capacity was estimated by ability to chew 11 food items. RESULTS: The prevalence of depressive symptoms was 17.5%. Self-evaluated oral health, chewing capacity and the number of natural and decayed teeth were associated with depressive symptoms. After adjusting for multiple confounders, chewing capacity (PR 1.93; 95% CI 1.34-2.79) and decayed teeth (PR 1.68; 95% CI 1.03-2.75) maintained a significant association with depressive symptoms. CONCLUSION: The direction of causality between oral health and depression is unclear; however, oral health may contribute to depression in older Australian men and depressive symptoms may limit chewing capacity and be aggravated by untreated dental decay.

Mortality Paradox of Older Italian-Born Men in Australia: The Concord Health and Ageing in Men Project.

Italian migrants are one of the largest groups of older migrants in Australia. Past research has found lower mortality rates in Italian migrants but it is unclear if this persists into older age. Data came from 334 Italian-born and 849 Australian-born men aged 70 years and over participating in a longitudinal study of men's ageing. Male Italian migrants were more likely to smoke, be overweight, and have lower socio-economic status (SES). They also had higher morbidity from diabetes, chronic pain, dementia and depressive symptoms but lower morbidity from heart disease and cancer. There was no age-adjusted mortality difference. However, adjusting for SES, lifestyle and morbidity differences revealed a 25% lower mortality rate (adjusted HR = 0.75; 95% CI 0.57, 0.98) in Italian-born men. Compared to their Australian-born counterparts, older Italian-born men have a lower mortality than expected considering their lower SES, higher smoking and higher morbidity.
