The influence of the COVID-19 pandemic on physical activity in Stockholm County - Evidence from time series models of smartphone measured daily steps data spanning over 3 years

BACKGROUND

It has been reported that physical activity levels decreased during the COVID-19 pandemic. Previous studies often relied on self-reported physical activity, which has low accuracy. Studies based on objectively measured physical activity have had short data collection periods, thereby not allowing the consideration of pre-pandemic levels of physical activity or the influence over the different waves of the pandemic.

METHODS

In this study, we utilize smartphone-measured step data from a nonprobability sample in Stockholm County, Sweden, where measures to limit the spread of COVID-19 differed from those in many other countries. The results are based on 522 individuals and 532,739 person-days with step data spanning from 2019 to 2021. Generalized additive models were fitted for each individual, and meta-regression was used to combine the results from individual models.

RESULTS

Daily steps decreased during the first wave but increased during the third wave compared to individual pre-pandemic levels. The decrease in daily steps occurred primarily in young individuals and those with occupations allowing remote work. Individuals of retirement age on the contrary increased their daily steps during the same period.

CONCLUSIONS

This study reveal that the influence of the COVID-19 pandemic was temporary and that younger age and the possibility of working from home were associated with a decreasing trend in physical activity.

Observational study of selective screening for prediabetes and diabetes in a real-world setting: an interprofessional collaboration method between public dental services and primary health care in Sweden

OBJECTIVE

Describe a method in a real-world setting to identify persons with undiagnosed prediabetes and type 2 diabetes through an interprofessional collaboration between Public Dental Services and Primary Health Care in Regions Stockholm.

DESIGN

A descriptive observational study.

SETTING

The study was conducted at seven sites in the region of Stockholm, Sweden. Each collaborating site consisted of a primary health clinic and dental clinic.

SUBJECTS

Study participants included adults over 18 years of age who visited the Public Dental Services and did not have a medical history of prediabetes or type 2 diabetes.

MAIN OUTCOME MEASURES

Selective screening is conducted in accordance with a risk assessment protocol at the Public Dental Services. In the investigated method, DentDi (Dental and Diabetes), adults diagnosed with caries and/or periodontitis over a cut-off value are referred to the Primary Health Care clinic for screening of prediabetes and type 2 diabetes.

RESULTS

DentDi, introduced at seven sites, between the years 2017 and 2020, all of which continue to use the method today. A total of 863 participants from the Public Dental Services were referred to the Primary Health Care. Of those 396 accepted the invitation to undergo screening at the primary health care centre. Twenty-four individuals did not meet the inclusion criteria, resulting in a total of 372 persons being included in the study. Among the 372 participants, 27% (101) had elevated glucose levels, of which 12 were diagnosed with type 2 diabetes and 89 with prediabetes according to the study classification.

CONCLUSIONS

DentDi is a feasible method of interprofessional collaboration where each profession contributes with the competence included in everyday clinical practice for early identification of persons with prediabetes and type 2 diabetes with a complete chain of care. The goal is to disseminate this method throughout Stockholm County and even other regions in Sweden.

Should Nicotine Replacement Therapy be Provided Free of Charge? A Cost-Utility Analysis in Sweden

INTRODUCTION

Treatment with nicotine replacement therapy (NRT) during an attempt to quit smoking increases the likelihood of success by about 55%. However, out-of-pocket payment for NRT can hinder its use.

AIMS AND METHODS

This study aims therefore to assess the cost-effectiveness of subsidizing NRT in Sweden. A homogeneous cohort-based Markov model was used to assess the lifetime costs and effects of subsidized NRT from a payer and societal perspective. Data to populate the model were retrieved from the literature, and selected parameters were varied in deterministic and probabilistic sensitivity analyses to assess robustness of model outputs. Costs are presented in USD, year 2021.

RESULTS

A 12-week treatment with NRT was estimated to cost USD 632 (474-790) per person. From a societal perspective, subsidized NRT was a cost-saving alternative in 98.5% of the simulations. NRT is cost-saving across all ages, but the health and economic gains are somewhat larger among younger smokers from a societal perspective. When a payer perspective was used, the incremental cost-effectiveness ratio was estimated at 14 480 (11 721-18 515) USD per QALY which was cost-effective at a willingness to pay of 50 000 USD per QALY in 100 % of the simulations. Results were robust with realistic changes in the inputs during scenario and sensitivity analyses.

CONCLUSIONS

Subsidizing NRT is potentially a cost-saving smoking cessation strategy from a societal perspective and cost-effective from a payer perspective.

IMPLICATIONS

This study found that subsidizing NRT is potentially a cost-saving smoking cessation policy alternative compared to current practice from a societal perspective. From a healthcare payer perspective, subsidizing NRT is estimated to cost USD 14 480 to gain an extra QALY. NRT is cost-saving across all ages, but the health and economic gains are somewhat larger among younger smokers from a societal perspective. Moreover, subsidizing NRT removes the financial barriers that are mostly faced by socioeconomically disadvantaged smokers which might reduce health inequalities. Thus, future economic evaluations should further investigate the health inequality impacts with methods that are more suitable for this.

Cost-effectiveness of superabsorbent wound dressing versus standard of care in patients with moderate-to-highly exuding leg ulcers

OBJECTIVE

To determine the cost-effectiveness/utility of a superabsorbent wound dressing (Zetuvit Plus Silicone) versus the current standard of care (SoC) dressings, from the NHS perspective in England, in patients with moderate-to-high exudating leg ulcers.

METHOD

A model-based economic evaluation was conducted to analyse the cost-effectiveness/utility of a new intervention. We used a microsimulation state-transition model with a time horizon of six months and a cycle length of one week. The model uses a combination of incidence base and risk prediction approach to inform transition probabilities. All clinical efficiency, health-related quality of life (HRQoL), cost and resource use inputs were informed by conducting a systematic review of UK specific literature.

RESULTS

Treatment with the superabsorbent dressing leads to a total expected cost per patient for a six month period of £2887, associated with 15.933 expected quality adjusted life weeks and 10.9% healing rate. When treated with SoC, the total expected cost per patient for a six month period is £3109, 15.852 expected quality adjusted life weeks and 8% healing rate. Therefore, the superabsorbent dressing leads to an increase in quality-adjusted life weeks, an increase in healing rate by 2.9% and a cost-saving of £222 per single average patient over six months. Results of several scenario analyses, one-way deterministic sensitivity analysis, and probabilistic sensitivity analysis confirmed the robustness of base-case results. The probabilistic analysis confirmed that, in any combination of variable values, the superabsorbent dressing leads to cost saving results.

CONCLUSION

According to the model prediction, the superabsorbent dressing leads to an increase in health benefits and a decrease in associated costs of treatment.

A systematic review of economic evaluations of public health interventions targeting alcohol, tobacco, illicit drug use and problematic gambling: Using a case study to assess transferability

AIMS

To identify and assess the cost-effectiveness of public health interventions targeting the use of alcohol, illicit drugs and tobacco, as well as problematic gambling behavior (ANDTS), and consider whether the results from these evaluations are transferable to the Swedish setting.

METHODS

A systematic review of economic evaluations within the area of ANDTS was conducted including studies published between January 2000 and November 2018, identified through Medline, PsychINFO, Web of Science, the National Health Service Economic Evaluation Database and Health Technology Assessment. The quality of relevant studies and the possibilities of transferring results were assessed using criteria set out by the Swedish Agency for Health Technology Assessment.

RESULTS

Out of 54 relevant studies, 39 were of moderate to high quality and included in the review, however none for problematic gambling. Eighty-one out of a total of 91 interventions were cost-effective. The interventions largely focusing on taxed-based policies or screening and brief interventions. Thirteen of these studies were deemed to have high potential for transferability, with effect estimates considered relevant, and with good feasibility for implementation in Sweden.

CONCLUSIONS

Interventions targeting alcohol- and illicit-drug use and tobacco use are cost-effective approaches, and results may be transferred to the Swedish setting. Caution must be taken regarding cost estimates and the quality of the evidence which the studies are based upon.

Economic evaluations of public health interventions for physical activity and diet: systematic review

Background

Physical inactivity and unhealthy dietary habits are associated with an increased disease and economic burden. Despite the prevalence of different public health programs, decision-makers encounter a multitude of challenges in prioritizing interventions for optimal resource allocation. The aim of this systematic review, therefore, was to identify economic evaluations of public health interventions targeting physical activity and healthy diet, and assess the quality and transferability of the findings to the Swedish context.

Methods

A search of published economic evaluations was conducted through electronic databases including PubMed, Web of Science, PsycINFO, National Health Service Economic Evaluation Databases (NHS EED) and the Health Technology Assessment Database (HTA). An additional search was done using references of relevant systematic reviews and, websites of relevant organizations were checked to find grey literature. Quality and transferability of the economic evaluations were appraised using a quality assessment tool developed by the Swedish Agency for Health Technology Assessment.

Preliminary Results

Thirty-two economic evaluations of 178 interventions were included; thirteen studies targeting physical activity, thirteen targeting healthy diet and six targeting both. The interventions varied in terms of their content, setting, mode of delivery and target populations. A majority of the economic evaluations reported that the interventions were likely to be cost-effective; however, considerable variations in the methodological and reporting qualities were observed. Only half of the economic evaluations were rated to have a high probability of transferring to the Swedish context.

Conclusions

Most of the interventions were reported to be cost-effective. However, a variation in quality and transferability of the available evidence to the Swedish context were observed.

Key messages

Public health interventions targeting physical activity and dietary habits have a high potential to be cost-effective. Decision makers should consider transferability and suitability of findings of economic evaluation from a different context to a decision problem at hand.

Economic evaluations of public health interventions for mental health: A systematic literature review

Background

To review the literature on economic evaluations of public health interventions targeting prevention of mental health problems and suicide, to support evidence based societal resource allocation.

Methods

A systematic review of economic evaluations within mental health and suicide prevention was conducted including studies published between 2000 and 2018. The studies were identified through Medline, PsychINFO, Web of Science. The quality of relevant studies and the transferability of their results were assessed using a criterion set out by the Swedish Agency for Health Technology Assessment.

Results

Nineteen studies of moderate to high quality were included in this review, which evaluated 18 interventions in mental health and 4 interventions in suicide prevention. Fourteen (63%) of all interventions were cost-effective. None of the studies that evaluated suicide prevention was of high quality. The interventions largely focused on psychological interventions at school, the workplace and within elderly care as well as screening and brief interventions in primary care. Nine studies (around 50% of included articles) had a high potential for transferability to the Swedish context.

Conclusions

Public health interventions aiming to improve mental health have a high potential to be economically beneficial to society, but high-quality evidence on the cost-effectiveness of suicide prevention is limited.

Key messages

Public health interventions aiming to improve mental health have a high potential to be economically beneficial to society. Evidence on the cost-effectiveness of suicide prevention is limited.

Narrative review of interventions suitable for well-baby clinics to promote infant attachment security and parents' sensitivity

AIM

The aim of this narrative review was to evaluate the evidence for interventions for children's secure attachment relationships and parents' caregiving sensitivity that could potentially be implemented in the context of a well-baby clinic.

METHODS

Literature search on programmes for parental caregiving sensitivity and secure attachment for infants aged 0-24 months. Randomised controlled trials (RCTs) published 1995-2018 with interventions starting from one week postpartum, and with a maximum of 12 sessions (plus potential booster session) were included.

RESULTS

We identified 25 studies, of which 22 studied effects of home-based programmes using video feedback techniques. Positive effects of these interventions in families at risk were found on parental caregiving sensitivity and to a lesser extent also on children's secure or disorganised attachment. The effects of two of these programmes were supported by several RCTs. Three intervention studies based on group and individual psychotherapy showed no significant positive effects. Most of the interventions targeted mothers only.

CONCLUSION

The review found some evidence for positive effects of selective interventions with video feedback techniques for children's secure attachment and strong evidence for positive effects on parental caregiving sensitivity. Important knowledge gaps were identified for universal interventions and interventions for fathers and parents with a non-Western background.
