Future of an ageing population evidence review; Developing medical fitness and wellbeing environments to maintain health and wellbeing over the lifecourse.
Background and methods
This report is derived from a review of the research evidence on physical activity interventions
and initiatives, interventions to support self-management/ self-care of long-term conditions and
digitally enabled care services and technologies. The aim was to use existing evidence to
envision future services and associated infrastructure.
The Evidence Review involved scoping the literature for topics researched and to determine the
nature of that research. Rapid-scoping review methods were applied to trusted sources, and
searches for specific key texts were conducted. A separate search was conducted to identify
literature relevant to each domain. A narrative was then produced from the review findings.
Review findings
The evidence base for physical activity interventions is growing. There has been significant
recent investment in the development and evaluation of interventions to promote activity and
reduce sedentary behaviour at the individual, community and population levels. The evidence to
link higher levels of physical activity to positive health outcomes and disease prevention is
convincing, both in ‘well’ populations and in those with long-term health conditions.
Self-management interventions are heterogeneous in nature but common elements exist across
the majority of them. The consensus in the literature is that self-management will become
increasingly important due to unsustainable demands upon services. Evaluation of selfmanagement
interventions reveals a small but varying effect across a wide range of outcomes.
However, little is known about the mechanisms by which these interventions work and how
these might vary across differing conditions and populations.
Technology is being increasingly used to support service delivery in a wide range of contexts,
and for the delivery of a variety of interventions including fitness and self-management. There is
strong evidence supporting the use of technology for remote monitoring of people with longterm
conditions, but further research is required.
Implications
Digital applications are already altering established patterns of service delivery. The findings
presented here reveal varying results of efficacy which do not accord with the optimistic future
described in various envisaging reports. Research has yet to consider unwanted and
unforeseen effects of moving towards technology-enabled services. It is also important to
consider how to effectively harness new health data emerging from the use of eHealth systems,
technology-enabled services and health-tracking devices.
There is an ongoing requirement to evaluate new technologies and technology-enabled
services in ways that provide both timely and robust answers, particularly as technology
development is a continually moving target. These considerations are discussed in this report
BMI transitions in Australian women: amount and causes of weight change associated with progression from healthy to unhealthy BMI over 16 years
Introduction and Aims: Progression from healthy weight to overweight or obesity is associated with numerous health problems in young adult women. The aims were to track BMI over 16 years in women who had a healthy BMI in 1996 (when they were 18-23), to calculate rates of weight change associated with maintenance and/or change in BMI, and to examine the determinants of these changes
Telemonitoring after discharge from hospital with heart failure: cost-effectiveness modelling of alternative service designs.
Objectives To estimate the cost-effectiveness of remote monitoring strategies versus usual care for adults recently discharged after a heart failure (HF) exacerbation.
Design Decision analysis modelling of cost-effectiveness using secondary data sources.
Setting Acute hospitals in the UK.
Patients Patients recently discharged (within 28 days) after a HF exacerbation.
Interventions Structured telephone support (STS) via human to machine (STS HM) interface, (2) STS via human to human (STS HH) contact and (3) home telemonitoring (TM), compared with (4) usual care.
Main outcome measures The incremental cost per quality-adjusted life year (QALY) gained by each strategy compared to the next most effective alternative and the probability of each strategy being cost-effective at varying willingness to pay per QALY gained.
Results TM was the most cost-effective strategy in the scenario using these base case costs. Compared with usual care, TM had an estimated incremental cost effectiveness ratio (ICER) of £11 873/QALY, whereas STS HH had an ICER of £228 035/QALY against TM. STS HM was dominated by usual care. Threshold analysis suggested that the monthly cost of TM has to be higher than £390 to have an ICER greater than £20 000/QALY against STS HH. Scenario analyses performed using higher costs of usual care, higher costs of STS HH and lower costs of TM do not substantially change the conclusions.
Conclusions Cost-effectiveness analyses suggest that TM was an optimal strategy in most scenarios, but there is considerable uncertainty in relation to clear descriptions of the interventions and robust estimation of costs
Client and facility level determinants of quality of care in family planning services in Ethiopia: multilevel modelling
Over the last two decades, while contraceptive use has improved in Ethiopia, the contraceptive prevalence rate remains low. In addition to socio-demographic and cultural factors, the quality of care in Family Planning (FP) services is an important determining factor of FP utilization. However, little research exists on the determinants of quality of care in FP services in Ethiopia. This study aims to identify the client and facility level determinants of quality of care in FP services in Ethiopia.This study was based on the first Ethiopian Services Provision Assessment Plus (ESPA+) survey conducted in 2014. A total of 1247 clients nested in 374 health facilities were included in the analysis. Multilevel mixed-effects logistic regression modelling was conducted. The outcome variable, client satisfaction, was created using polychoric principal component analysis using eleven facets that reflect client satisfaction.The results showed that both client-level and facility-level factors were associated with quality of care in FP services in Ethiopia. At the client-level; provision of information on potential side effects of contraceptive method (AOR = 5.22, 95% CI: 2.13-12.80), and number of history and physical assessments (AOR = 1.19, 95% CI: 1.03-1.34) were positively associated with client satisfaction, whereas waiting times of 30 minutes to two hours (AOR = 0.11, 95% CI: 0.03-0.33) was negatively associated with client satisfaction. At the facility-level; urban location (AOR = 4.61, 95% CI: 1.04-20.58), and availability of FP guidelines/protocols for providers (AOR = 4.90, 95% CI: 1.19-20.19) had positive significant effect on client satisfaction.Quality improvement programs in FP services in Ethiopia should focus on shortening waiting times and provision of information about the potential side effects of contraceptive methods. It is also important to improve health providers' skills in thorough client history taking and physical assessment. Further distribution and implementation of best practice guidelines for providers working in the FP services must be a priority.Gizachew Assefa Tessema, Mohammad Afzal Mahmood, Judith Streak Gomersall, Yibeltal Assefa, Theodros Getachew Zemedu, Mengistu Kifle, Caroline O.

Australia and Other Nations are Failing to Meet Sedentary Behaviour Guidelines for Children: Implications and a Way Forward
BACKGROUND: Australia has joined a growing number of nations which have evaluated the physical activity and sedentary behaviour status of their children. Australia received a 'D minus' in the first Active Healthy Kids Australia Physical Activity Report Card. METHODS: An expert subgroup of the Australian Report Card Research Working Group iteratively reviewed available evidence to answer three questions: 1) What are the main sedentary behaviours of children?, 2) What are the potential mechanisms for sedentary behaviour to impact on child health and development? and, 3) What are the effects of different types of sedentary behaviours on child health and development? RESULTS: Neither sedentary time nor screen time are homogeneous activities likely to result in homogenous effects. There are several mechanisms by which various sedentary behaviours may positively or negatively affect cardiometabolic, neuro-musculoskeletal, and psycho-social health, though the strength of evidence varies. National surveillance systems, and mechanistic, longitudinal and experimental studies are needed for Australia and other nations to improve their grade. CONCLUSIONS: Despite limitations, available evidence is sufficiently convincing that the total exposure and pattern of exposure to sedentary behaviours are critical to the healthy growth, development and wellbeing of children. Nations therefore need strategies to address these common behaviours
Ten-Year Analysis of Bacterial Colonisation and Outcomes of Major Burn Patients with a Focus on Pseudomonas aeruginosa
A retrospective descriptive study included patients admitted with severe burns over the course of 10 years (2008–2018). Across all patients, there were 39 different species of bacteria, with 23 species being Gram-negative and 16 being Gram-positive bacteria, with also five different species of fungi cultured. Pseudomonas aeruginosa was the most commonly isolated organism, with 57.45% of patients having a positive culture. There was a significant difference in the number of P. aeruginosa isolated from patients that acquired their burns at work, in a garden, inside a vehicle, in a garage or in a public place. In patients that were positive for P. aeruginosa, the number of operations was higher (2.4) and the length of stay was significantly increased (80.1 days). Patients that suffered from substance abuse demonstrated significantly higher numbers of isolated P. aeruginosa (14.8%). Patients that suffered from both mental health illness and substance abuse demonstrated significantly higher numbers of P. aeruginosa isolated (18.5%). In the P. aeruginosa-negative group, there were significantly fewer patients that had been involved in a clothing fire. Furthermore, in the P. aeruginosa-negative patient cohort, the mortality rate was significantly higher (p = 0.002). Since the incidence of P. aeruginosa was also associated with a decreased mortality rate, it may be that patients admitted to hospital for shorter periods of time were less likely to be colonised with P. aeruginosa. This study demonstrates novel factors that may increase the incidence of P. aeruginosa isolated from burn patients
