Pneumococcal Conjugate Vaccines Turning the Tide on Inequity: A Retrospective Cohort Study of New Zealand Children Born 2006-2015.

BACKGROUND: Hospitalization rates for infectious diseases in New Zealand (NZ) children have increased since 1989. The highest burden is among Maori and Pacific children, and the most socioeconomically deprived. New Zealand introduced pneumococcal conjugate vaccine (PCV)7 in June 2008, PCV10 in 2011, and PCV13 in 2014. METHODS: A retrospective cohort study of NZ children aged <6 years between 2006 and 2015 was performed using administrative databases. Demographics and hospitalizations were linked to evaluate the impact of the PCV vaccination program on cases of invasive pneumococcal disease (IPD), all-cause pneumonia (ACP), and otitis media (OM), defined by ICD-10-AM codes, and to explore the effect by ethnicity and deprivation. RESULTS: Between 2006 and 2015, there were 640 children hospitalized with IPD, 26589 for ACP, and 44545 for OM. IPD hospitalizations declined by 73% between 2005 and 2015 for children <6 years of age, whereas ACP and OM declined by 8% and 25%, respectively. The highest rates for all diseases were among Maori and Pacific children and those from high deprivation. However, the declines were highest among Maori and Pacific children and those from socioeconomically deprived areas. IPD hospitalizations declined by 79% and 67% for Maori and Pacific children, respectively, between 2006 and 2015. ACP declined by 12% in Maori and 21% in Pacific children. OM declined by 51% in Maori children. CONCLUSION: In contrast to the increasing trend of hospitalization rates for infectious disease in New Zealand, the use of PCV appears associated with reductions in ethnic and socioeconomic disparities in hospitalization for IPD, ACP, and OM.

Comparative effectiveness of metformin versus insulin for gestational diabetes in New Zealand.

PURPOSE: To measure the comparative effectiveness of metformin versus insulin for initial pharmacological management of gestational diabetes mellitus (GDM). METHODS: We conducted a population-based retrospective cohort study using administrative claims, maternity care, and laboratory result data from New Zealand. We followed pregnant women aged 15 to 45 from GDM diagnosis through delivery and assessed outcomes using maternity care and hospitalization data. We adjusted for covariates using inverse probability of treatment weights and multiple imputation for missing covariate information. We estimated unadjusted and adjusted risk ratios (RRs), risk differences (RDs) per 100, and 95% confidence intervals (CIs). Linear regression was used to estimate the association of treatment with birthweight. We stratified analyses by ethnicity and infant sex in prespecified sensitivity analyses. RESULTS: We compared 3818 metformin-treated pregnancies with 3450 insulin-treated pregnancies. We observed differences in treatment initiation by ethnicity, socioeconomic status, region, and calendar year. Treatment groups were similar in age, body mass index (BMI), and timing of diagnosis/treatment initiation. After adjustment, metformin was associated with reduced absolute risk of planned elective c-section (RD = -2.3, 95% CI, -4.3 to -0.3), large for gestational age (RD = -3.7, 95% CI, -5.5 to -1.8), and neonatal hypoglycemia (RD = -5.0, 95% CI, -6.9 to -3.2) compared with insulin. There were no clinically meaningful differences in average birthweight between metformin- and insulin-treated pregnancies. We observed variation in estimates by ethnicity and infant sex for some neonatal outcomes. CONCLUSION: Metformin appears to be an effective treatment for women with GDM and may reduce risk of some adverse neonatal outcomes when compared with insulin.

Cardiorespiratory fitness is positively associated with a healthy dietary pattern in New Zealand adolescents.

OBJECTIVE: To examine the association between cardiorespiratory fitness and dietary patterns in adolescents. DESIGN: Food choice was assessed using the validated New Zealand Adolescent FFQ. Principal components analysis was used to determine dietary patterns. Trained research assistants measured participants' height and body mass. Cardiorespiratory fitness was assessed in a subset of participants using the multistage 20 m shuttle run. The level and stage were recorded, and the corresponding VO2max was calculated. Differences in mean VO2max according to sex and BMI were assessed using t tests, while associations between cardiorespiratory fitness and dietary patterns were examined using linear regression analyses adjusted for age, sex, school attended, socio-economic deprivation and BMI. SETTING: Secondary schools in Otago, New Zealand. SUBJECTS: Students (n 279) aged 14-18 years who completed an online lifestyle survey during a class period. RESULTS: Principal components analysis produced three dietary patterns: 'Treat Foods', 'Fruits and Vegetables' and 'Basic Foods'. The 279 participants who provided questionnaire data and completed cardiorespiratory fitness testing had a mean age of 15·7 (sd 0·9) years. Mean VO2max was 45·8 (sd 6·9) ml/kg per min. The 'Fruits and Vegetables' pattern was positively associated with VO2max in the total sample (ß=0·04; 95%CI 0·02, 0·07), girls (ß=0·06; 95% CI 0·03, 0·10) and boys (ß=0·03; 95% CI 0·01, 0·05). CONCLUSIONS: These results indicate that increase in cardiorespiratory fitness was associated with a healthier dietary pattern, suggesting both should be targeted as part of a global lifestyle approach. Longitudinal studies are needed to confirm this association in relation to health outcomes in New Zealand adolescents.

Diet quality is associated with measures of body fat in adolescents from Otago, New Zealand.

OBJECTIVE: To examine the potential associations between diet quality and multiple measures of body composition in a sample of New Zealand adolescents aged 14-18 years. DESIGN: Cross-sectional survey of eleven high schools in Otago, New Zealand. Each participant completed an online FFQ and a New Zealand Diet Quality Index for Adolescents (NZDQI-A) score was calculated based on variety and adequacy of intake for five major food groups. Besides height and waist circumference measurements, body composition was assessed using segmental bio-impedance analysis. Generalized estimating equations were used to examine associations between diet quality and body composition in models adjusted for sex, age, ethnicity and socio-economic status. SETTING: High schools in Otago, New Zealand. SUBJECTS: High-school students (n 681, 56 % male, mean age 16·1 (sd 1·5) years) participating in the Otago School Students Lifestyle Survey Two. RESULTS: Higher NZDQI-A scores were significantly associated with lower body fat percentage (ß=-0·19; 95 % CI -0·35, -0·04; P=0·014), fat-to-lean mass ratio (ß=-0·26; 95 % CI -0·46, -0·05; P=0·016) and lower fat mass index (ß=-0·23; 95 % CI -0·45, -0·004; P=0·046) after multivariate adjustment. No association was found between NZDQI-A and BMI, waist circumference or waist-to-height ratio. CONCLUSIONS: Diet quality, as measured by NZDQI-A, was associated only with measures of body fat, not measures of overall body size. Measures specific to body fat should be used for more accurate ascertainment of body composition in examining the diet-body composition associations in this age group.

Fluid and electrolyte balance during two different preseason training sessions in elite rugby union players.

The purpose of this study was to compare fluid balance between a resistance and an aerobic training sessions, in elite rugby players. It is hypothesized that resistance exercise will result in a higher prevalence of overdrinking, whereas during the aerobic session, underdrinking will be more prevalent. As with previous fluid balance studies, this was an observational study. Twenty-six players completed the resistance training session, and 20 players completed the aerobic training session. All players were members of an elite rugby union squad competing in the southern hemisphere's premier competition. For both sessions, players provided a preexercise urine sample to determine hydration status, pre- and postexercise measures of body mass, and blood sodium concentration were taken, and the weight of drink bottles were recorded to calculate sweat rates and fluid intake rates. Sweat patches were positioned on the shoulder of the players, and these remained in place throughout each training session and were later analyzed for sodium concentration. The percentage of sweat loss replaced was higher in the resistance (196 ± 130%) than the aerobic training session (56 ± 17%; p = 0.002). Despite this, no cases of hyponatremia were detected. The results also indicated that more than 80% of players started training in a hypohydrated state. Fluid intake seems to differ depending on the nature of the exercise session. In this group of athletes, players did not match their fluid intakes with their sweat loss, resulting in overdrinking during resistance training and underdrinking in aerobic training. Therefore, hydration strategies and education need to be tailored to the exercise session. Furthermore, given the large number of players arriving at training hypohydrated, improved hydration strategies away from the training venue are required.

Dieting status influences associations between dietary patterns and body composition in adolescents: a cross-sectional study.

BACKGROUND: Associations between food choice and body composition in previous studies of adolescents have been inconsistent. This may be due to the body composition measures used, or these associations may be affected by the dieting status of adolescents. The objective of this study was to investigate the association between dietary patterns and body composition in adolescents, and determine if these associations are moderated by dieting status. METHODS: Information on food consumption and current dieting status was collected, using a web-based survey, in 681 adolescents (mean age 15.8 (SD 0.9) years) from schools in Otago, New Zealand. Non-dieters were defined as those reporting not being on a diet as they were "happy with their weight". Principal components analysis (PCA) was used to determine dietary patterns. Body mass index (BMI), waist circumference (WC), waist-to-height ratio (WHtR), fat mass index (FMI), and fat-free mass index (FFMI) were examined as outcomes. Generalized estimating equations were used to examine associations between dietary patterns and body composition. RESULTS: PCA produced three dietary patterns: 'Treat Foods', 'Fruits and Vegetables', and 'Basic Foods'. A standard deviation increase in 'Basic Foods' was associated with a 3.58% decrease in FMI (95%CI -6.14, -0.94) in the total sample. When separate sex analysis was undertaken significant negative associations were found in boys only, between the 'Basic Food' score and WC, WHtR, FMI, and FFMI, while the 'Fruits and Vegetables' pattern was negatively associated with FMI. Associations between 'Treat Foods' and BMI, WC, and WHtR in non-dieters were positive, while these associations were negative for all other participants. CONCLUSIONS: Significant associations were found between dietary patterns and indices of both central and total adiposity, but not BMI. Therefore using only BMI measures may not be useful in this age group. Since our results were significant for boys and not girls, nutrition messages designed to prevent obesity may be particularly important for adolescent boys. As an interaction between dieting status and 'Treat Foods' existed, future studies should also explore the role of dieting when investigating food choice and body composition.

Sleep duration and adiposity in older adolescents from Otago, New Zealand: relationships differ between boys and girls and are independent of food choice.

BACKGROUND: While relationships between sleep and BMI have been extensively studied in younger children the effect of sleep duration on adiposity in adolescents, who are undergoing rapid growth periods, is less well known. There is also a lack of consistent evidence on the role of sleep on other measures of adolescent body composition which may be more reflective of health than BMI in this age group. Previous research investigating whether these relationships differ between sexes is also inconsistent. Therefore the objective of this study was to investigate relationships between sleep duration and multiple body composition measures in older adolescents and to investigate if these relationships differ between boys and girls. METHODS: A web-based cross-sectional survey and anthropometric measurement of 685 adolescents (mean age 15.8 years) from 11 schools in Otago, New Zealand. Height and weight were measured by trained researchers and fat mass and fat-free mass were estimated using bio-impedance. Generalised estimating equations were used to examine associations between sleep duration and the following body composition measures: BMI, waist circumference (WC), waist-to-height ratio (WHtR), fat mass index (FMI), and fat-free mass index (FFMI). Analyses were adjusted for ethnicity, deprivation, the number of screens in the bedroom and fruit and vegetable consumption. RESULTS: When data from all participants were analysed together, no significant relationships were seen between sleep duration and any body composition measure but significant sex interactions were seen. An hour increase in average nightly sleep duration in boys only was associated with decreases of 1.2% for WC, 0.9% for WHtR, 4.5% for FMI and 1.4% for FFMI in multivariate models. Similar results were seen for weekday and weekend night sleep duration. CONCLUSIONS: Sex specific factors may play a role in relationships between sleep and body composition in older adolescents. The results in boys were most pronounced for FMI, a measure of total adiposity, which suggests that insufficient sleep in adolescent boys may affect fat mass more than lean mass and that the use of measures such as BMI may result in an under-estimation of relationships.

Attitudes to food differ between adolescent dieters and non-dieters from Otago, New Zealand, but overall food intake does not.

OBJECTIVE: There is increasing pressure for adolescents to be thin and this may not always be acted upon in healthy ways; for example, certain foods or food groups may be restricted or meals skipped. As foods are not eaten in isolation it is useful to examine dietary patterns and associated psychosocial factors to better understand eating behaviour. The aim of the present study was to identify correlates of 'dieting' in adolescents from Otago, New Zealand. DESIGN: A web-based survey was conducted in 2009, collecting information on food consumption and factors potentially associated with food consumption. Principal components analysis was used to investigate dietary patterns. Correlates were examined in 1329 students using multiple logistic regression analysis. SETTING: Nineteen secondary schools in the province of Otago, New Zealand. SUBJECTS: Students from school years 9 and 10 (mean age 14.1 (SD 0.7) years). RESULTS: There was no relationship between dieting and dietary patterns. Those not dieting were 17 % (95 % CI 7, 26 %) more likely to eat lunch and 22 % (95 % CI 3, 37 %) more likely to eat an evening meal on one more weekday than those who were dieting. Those who reported dieting were more likely to report healthiness (OR = 2.18, 95 % CI 1.11, 4.26) as an important factor when choosing food and that eating fruit and vegetables makes you better looking. No sex by dieting interaction was found. CONCLUSIONS: In this cohort, while there was no difference in actual food consumption between dieters and non-dieters, there were significant differences in attitudes to food.

Development and validation of a food-based diet quality index for New Zealand adolescents.

BACKGROUND: As there is no population-specific, simple food-based diet index suitable for examination of diet quality in New Zealand (NZ) adolescents, there is a need to develop such a tool. Therefore, this study aimed to develop an adolescent-specific diet quality index based on dietary information sourced from a Food Questionnaire (FQ) and examine its validity relative to a four-day estimated food record (4DFR) obtained from a group of adolescents aged 14 to 18 years. METHODS: A diet quality index for NZ adolescents (NZDQI-A) was developed based on 'Adequacy' and 'Variety' of five food groups reflecting the New Zealand Food and Nutrition Guidelines for Healthy Adolescents. The NZDQI-A was scored from zero to 100, with a higher score reflecting a better diet quality. Forty-one adolescents (16 males, 25 females, aged 14-18 years) each completed the FQ and a 4DFR. The test-retest reliability of the FQ-derived NZDQI-A scores over a two-week period and the relative validity of the scores compared to the 4DFR were estimated using Pearson's correlations. Construct validity was examined by comparing NZDQI-A scores against nutrient intakes obtained from the 4DFR. RESULTS: The NZDQI-A derived from the FQ showed good reliability (r = 0.65) and reasonable agreement with 4DFR in ranking participants by scores (r = 0.39). More than half of the participants were classified into the same thirds of scores while 10% were misclassified into the opposite thirds by the two methods. Higher NZDQI-A scores were also associated with lower total fat and saturated fat intakes and higher iron intakes. CONCLUSIONS: Higher NZDQI-A scores were associated with more desirable fat and iron intakes. The scores derived from either FQ or 4DFR were comparable and reproducible when repeated within two weeks. The NZDQI-A is relatively valid and reliable in ranking diet quality in adolescents at a group level even in a small sample size. Further studies are required to test the predictive validity of this food-based diet index in larger samples.

Work satisfaction and intention to leave among direct care workers in community and residential aged care in Australia.

Turnover in the Australian aged-care workforce is lower than in the United States but is still of concern. This research examined the effects of worker satisfaction, worker characteristics, work conditions, and workplace environment on intention to leave, using data from a 2007 national census of the aged-care workforce. A probit model was used to estimate the probability of care workers leaving their jobs in the next 12 months. While workers were satisfied, overall, with their work, improving some components of satisfaction and converting casual contracts to permanent work would reduce intention to leave. To these ends, a shift in focus is required away from worker characteristics and the nature of care work to job conditions and organizational matters amenable to management and policy action.

Multi-decade national cohort identifies adverse pregnancy and birth outcomes associated with acute respiratory illness hospitalisations during the influenza season.

BACKGROUND: Despite the World Health Organization (WHO) recommendation that pregnant women be prioritised for seasonal influenza vaccination, coverage in the Western Pacific Region remains low. Our goal was to provide additional data for the Western Pacific Region about the value of maternal influenza vaccination to pregnant women and their families. METHODS: We conducted a 16-year retrospective cohort to evaluate risks associated with influenza-associated maternal acute respiratory infection (ARI) in New Zealand. ARI hospitalisations during the May to September influenza season were identified using select ICD-10-AM primary and secondary discharge codes from chapter J00-J99 (diseases of the respiratory system). Cox proportional hazards models were used to calculate crude and adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs). RESULTS: We identified 822,391 pregnancies among New Zealand residents between 2003 and 2018; 5095 (0.6%) had ≥1 associated ARI hospitalisation during the influenza season; these pregnancies were at greater risk of preterm birth (aHR 1.50, 95% CI 1.39-1.61) and low birthweight (aHR 1.64, 95% CI 1.51-1.79) than pregnancies without such hospitalisations. We did not find an association between maternal ARI hospitalisation and fetal death (aHR 0.96, 95% CI 0.69-1.34) during the influenza season. Maternal influenza vaccination was associated with reduced risk of preterm birth (aHR 0.79, 95% CI 0.77-0.82), low birthweight (aHR 0.87, 95% CI 0.83-0.90) and fetal death (aHR 0.50%, 95% CI 0.44-0.57). CONCLUSION: In this population-based cohort, being hospitalised for an ARI during the influenza season while pregnant was a risk factor for delivering a preterm or a low birthweight infant and vaccination reduced this risk.

A retrospective cohort study investigating the comparative effectiveness of pneumococcal vaccines against hospitalisation with otitis media and pneumonia in New Zealand.

BACKGROUND: Since 2008 New Zealand has used three different formulations of pneumococcal vaccines on the national infant schedule, PCV7, PCV10 and PCV13, switching between PCV10 and PCV13 twice in 10 years. We have used New Zealand's linkable, administrative health data to examine the comparative risk of otitis media (OM) and pneumonia hospitalisations among children receiving three different pneumococcal conjugate vaccines (PCV). METHODS: This was a retrospective cohort study using linked administrative data. Outcomes were otitis media, all cause pneumonia and bacterial pneumonia related hospitalisation for children in three cohorts representing periods where PCVs transitioned between PCV7, PCV10, PCV13 and back to PCV10 between 2011 and 2017. Cox's proportional hazard regression was used to provide hazard ratio estimates to compare outcomes for children vaccinated with different vaccine formulations and to adjust for different sub population characteristics. RESULTS: Each observation period, where different vaccine formulations coincided, and therefore comparable with respect to age and the environment, included over fifty-thousand infants and children. PCV10 was associated with a reduced risk for OM compared with PCV7 (Adjusted HR 0.89, 95 %CI 0.82-0.97). There were no significant differences between PCV10 and PCV13 in risk of hospitalisation with either otitis media or all-cause pneumonia amongst the transition 2 cohort. In the 18 -month follow-up, after transition 3, PCV13 was associated with a marginally higher risk of all-cause pneumonia and otitis media compared to PCV10. CONCLUSION: These results should offer reassurance about the equivalence of these pneumococcal vaccines against the broader pneumococcal disease outcomes OM and pneumonia.

Interventions to improve vaccine coverage of pregnant women in Aotearoa New Zealand.

Introduction Maternal vaccination against influenza and pertussis protects mothers and babies from severe disease and is recommended and funded in Aotearoa New Zealand. Despite this, maternal vaccination uptake is low, varies by region and is inequitable, with Maori and Pacific mama (mothers) less likely to receive vaccination. Aim To determine what interventions currently exist to support and encourage maternal vaccination against influenza and pertussis and what changes and interventions could be implemented to improve coverage, with a focus on Maori and Pacific hapu mama (pregnant mothers). Methods Interviews with six participants with diverse roles in the vaccination workforce were conducted. Participants were involved in education, certification and supporting vaccinators, high-level strategising, and vaccination. Interviews aimed to determine what interventions currently exist for hapu mama, what changes need to be made to improve coverage and how Maori and Pacific people have been specifically engaged. Qualitative data analysis was used to determine themes. Results Participants identified that interventions must focus on prioritising and emphasising the importance of maternal vaccination, promoting collaboration and innovation, making interventions accessible, and empowering Maori- and Pacific-driven avenues to vaccination. To create positive foundations, participants identified the importance of building and maintaining trust and affording mothers' time and autonomy in vaccination. Discussion Healthcare professionals need to proactively engage hapu mama about vaccination and collaborate in service delivery. Interventions must be suitably accessible and allow for the autonomy of hapu mama over vaccination decisions. Equity should be considered at the foundation of vaccine interventions to improve the accessibility of vaccines to all communities.

Stabilising the aged care workforce: an analysis of worker retention and intention.

Concerns about the capacity of the aged care industry to attract and retain a workforce with the skills required to deliver high quality care are widespread, but poor conceptualisation of the problem can result in strategies to address turnover being poorly targeted. A census of residential and community aged care services conducted by the National Institute of Labour Studies (NILS) in 2007 provided a comprehensive empirical account of the workforce, and estimated turnover on the basis of retention: that is, the proportion of the workforce who had been in their job for 1 year or less. This paper adds the dimension of intention: that is, workers' expectations as to whether in 1 year's time, they would still be working in the same aged care service. The dual driver model that takes both retention and intention into account was applied in further analysis of the 2007 NILS data. Investigation of relationships between workforce instability and 13 variables covering worker attributes, organisational attributes and structural attributes of the industry demonstrated the usefulness of the dual driver model for reconceptualising and analysing stability and, in turn, refining strategies to address turnover.

Evidence of suboptimal maternal vaccination coverage in pregnant New Zealand women and increasing inequity over time: A nationwide retrospective cohort study.

BACKGROUND: Adequate maternal vaccination coverage is critical for the prevention and control of infectious disease outbreaks such as pertussis, influenza, and more recently COVID-19. To guide efforts to increase vaccination coverage this study examined the extent of vaccination coverage in pregnant New Zealand women over time by area-level deprivation and ethnicity. METHODS: A retrospective cohort study was used consisting of all pregnant women who delivered between 01 January 2013 and 31 December 2018, using administrative health datasets. Outcomes were defined as receipt of influenza or pertussis vaccination in any one of the relevant data sources (National Immunisation Register, Proclaims, or Pharmaceutical collection) during their eligible pregnancy. Ethnicity was prioritised as Maori (NZ indigenous), Pacific, Asian, and Other or NZ European and deprivation was defined using New Zealand Index of Multiple Deprivation (IMD). RESULTS: Between 2013 and 2018, Asian women had the highest maternal vaccination coverage (36%) for pertussis, while Maori and Pacific women had the lowest, 13% and 15% respectively. Coverage of pertussis vaccination during pregnancy in low deprivation Maori women was 24% and 28% in Pacific women. This is in comparison to 30% and 25% in high deprivation Asian and European/Other women, respectively. Similar trends were seen for influenza. CONCLUSION: Between 2013 and 2018 maternal vaccination coverage increased for pertussis and influenza. Despite this coverage remains suboptimal, and existing ethnic and deprivation inequities increased. There is an urgent need to focus on equity, to engage and support ethic communities by creating genuinely accessible, culturally appropriate health services.

Increasing Uptake of Maternal Pertussis Vaccinations through Funded Administration in Community Pharmacies.

Although maternal pertussis vaccination is recommended, uptake is suboptimal in New Zealand (NZ), despite full funding in general practice and hospitals. We determined whether funding maternal pertussis vaccination in community pharmacy increases its uptake. Pertussis vaccination during pregnancy was compared between non-contiguous, demographically similar regions of NZ. The pertussis vaccine was funded at pharmacies from Nov 2016 in one NZ region (Waikato), but not in comparator regions (Northland, Hawkes Bay). Vaccinations during pregnancy were determined from the National Immunisation Register, general practice and pharmacy claims data, and a maternity database. Comparisons were made using adjusted odds ratios (OR) and 95% confidence intervals (CI) for Nov 2015 to Oct 2016 versus Nov 2016 to Oct 2019. The odds of pregnancy pertussis vaccination increased in the post-intervention versus pre-intervention period with this increase being larger (p = 0.0014) in the intervention (35% versus 21%, OR = 2.07, 95% CI 1.89-2.27) versus the control regions (38% versus 26%, OR = 1.67, 95% CI 1.52-1.84). Coverage was lower for Maori versus non-Maori, but increased more for Maori in the intervention versus control regions (117% versus 38% increase). It was found that funding maternal pertussis vaccination in pharmacy increases uptake, particularly for Maori women. Measures to increase coverage should include reducing barriers to vaccines being offered by non-traditional providers, including pharmacies.

The new dynamics of residential aged care in Australia: continuity and change.

ObjectiveThis paper tests the hypothesis that increases in recorded dependency levels of permanent residential aged care clients are associated with reduced length of stay and higher turnover. A secondary objective is to compare the Aged Care Funding Instrument with its predecessor, the Resident Classification Scale, on a common schema.MethodsAdministrative data for all Commonwealth-subsidised residential aged care services in Australia from 2008-09 to 2018-19 were obtained from the National Aged Care Data Clearinghouse. More than 750000 episodes of permanent residential aged care were analysed. The categories from the two rating systems were mapped to a six-level schema, primarily based on the dollar value of the categories at the time of transition.ResultsThere was a strong trend towards higher dependency ratings across admissions, residents, and separations. However, contrary to expectation, measures of system activity showed a slowing of the system: length of stay increased and turnover decreased.ConclusionsThe mapping of dependency rating schemes to a common rating enables the analysis of long-term trends in residential care dynamics. There is no evidence that the marked increases in reported dependency ratings led to accelerated system activity, consistent with an earlier study. This analysis forms a solid base for ongoing analysis of care appraisals in the context of a possible new rating scheme. It highlights the interplay between policy changes and provider behaviour, and the need for robust data to monitor care appraisals and system dynamics.What is known about the topic?Residential aged care subsidies are determined by care needs in relation to assessed dependency levels, using the Aged Care Funding Instrument since 2008, and before that, the Resident Classification Scale. Between 2008-09 and 2018-19, there was considerable growth in residents classified at more dependent levels, and this would be expected to result in greater turnover in the system.What does this paper add?This paper maps the rating schemes to a simplified, common rating that enables the analysis of long-term trends in residential care dynamics. It shows that the system is slowing, contrary to the trends expected if residents were more frail as the reported ratings imply. The paper examines possible explanations of these trends, and addresses policy implications.What are the implications for practitioners?In the context of a potential new client-dependency classification, this study shows the importance of robust measures of the dynamics of the system-and the underlying data-vis-à-vis the means by which client dependency is assessed.

Does the National Immunisation Register stack up? Quantifying accuracy when compared to parent-held health record books.

AIM: The National Immunisation Register (NIR), which is derived from general practice management systems, is an important tool for the provision of clinical services, national immunisation programme evaluation and immunisation research in New Zealand. However, the accuracy of the NIR data has not yet been quantified. This study aimed to examine, describe and quantify the extent of discrepancy in the NIR compared to Well Child Tamariki Ora parent-held health record books (Health Books). METHOD: Immunisation data for vaccinations given between birth and four years old for children born between 2006 and 2019 were compared between the Health Books and the NIR. Health Book records were used as the reference standard to calculate performance measures: sensitivity, specificity, positive and negative predictive values for the NIR. RESULTS: Overall, NIR performance was high: sensitivity ranged from 90% to 93%, specificity from 78% to 85%, the positive predictive value from 91% to 94% and the negative predictive value from 77% to 84%. NIR performance was higher for National Immunisation Schedule (NIS) vaccines compared with non-NIS vaccines. CONCLUSION: This study indicates the NIR data accuracy generally performs well compared with international equivalents, especially for NIS vaccine records. Further work is required to ascertain why discrepancies between the Health Books and NIR continue to occur, with particular attention to important subgroups and translating records across from migrant populations. Also, future work is required to understand the accuracy of vaccination records for groups who experience lower-quality healthcare and a higher burden of infectious diseases.

The role of sanctions in Australia's residential aged care quality assurance system.

OBJECTIVE: To assess the role of sanctions as the highest level of enforcement in Australia's residential aged care quality assurance (QA) system. ANALYSIS: of secondary data on accreditation activities and outcomes from 1999-2000 to 2007-08, extracted from the Annual Report on the Aged Care Act 1997. SETTING: A total of 138 sanctioned homes among all aged care homes in Australia (n = 2830 in 2007-08). MAIN OUTCOME MEASURES: Chi-square test of differences between sanctioned and non-sanctioned homes, and z scores to identify variables underlying differences. RESULTS: Sanctions are a rare event as more frequent enforcement actions at lower levels of regulatory action mean that a diminishing number of homes are subject to higher levels of action. Relationships between the risk of sanctions and characteristics of homes (state, size, sector and level of care) were evident. Sanctions provide only limited signals on quality to potential users and do not reflect the full scope of the QA process and the range of quality of care found. CONCLUSIONS: The effectiveness of sanctions in contributing to quality improvement has to be seen within the wider regulatory framework, which in turn has to be set in the context of other factors driving quality of care. Quality improvement in Australia and elsewhere will depend on further development of QA systems but will also require attention to wider contextual factors that contribute to quality outcomes, including quality of the aged care workforce.

How strong is the housing assets pillar of funding for residential aged care?

OBJECTIVE: To explore reasons for the gap between the perception that high home ownership provides a strong pillar of funding for aged care accommodation and the actuality of half of those in residential care having this cost met by the Accommodation Supplement. METHODS: Review of data from Australian Bureau of Statistics and administrative sources, and recent research studies. RESULTS: Trends in payment methods show continuing reliance on the Accommodation Supplement. Reasons are found in patterns of home ownership at older ages, changes in tenure and living arrangements over the age range, and increasing use of the exchange value of housing assets. Policy tensions arise between protecting access for low means residents and requiring those who are able to pay to do so. CONCLUSIONS: The housing assets pillar at advanced ages is not as strong as early in retirement and makes it increasingly unreliable as a source of funding.
