- To estimate the effect of a 3-year commitment to remain tobacco free on tobacco uptake among high school students in Sweden. The commitment is developed in the form of a contract between a child and a significant adult, constituting the core component of Tobacco-free Duo (T-Duo), a Swedish school-based tobacco prevention program. Secondary analysis of data from a cluster randomized controlled trial. Participants were 586 students in high schools assigned to the intervention arm of T-Duo. At inception, participants attended grade 7 (i.e., age 12–13). Only students who were tobacco naïve at baseline for the respective outcome and participated in all follow-ups were included. The exposure was defined as signing a 3-year contract with a significant adult, categorized as “stable contract” (3 years contract with the same contract partner), “unstable” (signed a contract sometime during follow-up but this was not sustained over time and/or with the same partner), and “no contract” at all during the intervention period. The primary outcome was having never tried cigarette smoking at the end of grade 9. Exposure and outcomes were self-reported in yearly questionnaires. Of 586 students, 321 (55%) held a stable contract, 204 (35%) an unstable contract, and 61 (10%) did not sign a contract at all. At the end of grade 9 (age 15–16), the relative risk (RR) to remain cigarette free was 1.11 (95% CI 1.00–1.22) (Number Needed to Treat = 10) among students in any type of contract compared to students that did not write a contract at all. The RRs for remaining tobacco free (secondary outcomes) ranged from 1.07 (0.98–1.16) for regular snus use to 1.16 (1.00–1.35) for any type of tobacco use. A commitment to remain tobacco free through a child–adult contract seems to exert a preventive effect on the uptake of tobacco use among Swedish adolescents over 3 school years. The current findings apply to a selected sample of both schools and students.Registration: Current Controlled Trials ISRCTN52858080 Date: January 4, 2019, retrospectively registered.

- BACKGROUND: Universal tobacco-prevention programs targeting youths usually involve significant adults, who are assumed to be important social influences. Commitment not to use tobacco, or to quit use, as a formal contract between an adolescent and a significant adult is a preventive model that has not been widely practiced or explored and has been formally evaluated even less. In this paper, we present the rationale and protocol for the evaluation of the Swedish Tobacco-free Duo program, a multicomponent school-based program the core of which rests on a formal agreement between an adolescent and an adult. The adolescent's commitment mainly concerns avoiding the onset of any tobacco use while the adult commits to support the adolescent in staying tobacco free, being a role model by not using tobacco themselves.OBJECTIVE: To assess (1) whether Tobacco-free Duo is superior to an education-only program in preventing smoking onset among adolescents and promoting cessation among their parents, (2) whether exposure to core components (adult-child agreement) entails more positive effects than exposure to other components, (3) the impact of the program on whole school tobacco use, (4) potential negative side effects, and (5) school-level factors related to fidelity of the program's implementation.METHODS: A mixed-design approach was developed. First, a cluster randomized controlled trial was designed with schools randomly assigned to either the comprehensive multicomponent program or its educational component only. Primary outcome at the adolescent level was identified as not having tried tobacco during the 3-year junior high school compulsory grades (12-15 years of age). An intention-to-treat cohort-wise approach and an as-treated approach complemented with a whole school repeated cross-sectional approach was devised as analytical methods of the trial data. Second, an observational study was added in order to compare smoking incidence in the schools participating in the experiment with that of a convenience sample of schools that were not part of the experimental study. Diverse secondary outcomes at both adolescent and adult levels were also included.RESULTS: The study was approved by the Umeå Regional Ethics Review Board (registration number 2017/255-31) in 2017. Recruitment of schools started in fall 2017 and continued until June 2018. In total, 43 schools were recruited to the experimental study, and 16 schools were recruited to the observational study. Data collection started in the fall 2018, is ongoing, and is planned to be finished in spring 2021.CONCLUSIONS: Methodological, ethical, and practical implications of the evaluation protocol were discussed, especially the advantage of combining several sources of data, to triangulate the study questions. The results of these studies will help revise the agenda of this program as well as those of similar programs.TRIAL REGISTRATION: International Standard Randomized Controlled Trial Number (ISRCTN) 52858080; https://doi.org/10.1186/ISRCTN52858080.INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): DERR1-10.2196/21100.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: Despite a long-term downward trend in smoking prevalence, tobacco remains the number one risk factor for death and disability in Sweden. Globally, tobacco use generates a substantial economic burden for health systems and is also a major driver of socioeconomic inequalities in health. This article describes the planned cost-effectiveness and health equity impact evaluation of a multicomponent school-based programme to prevent the onset of tobacco use in adolescents.Methods and analysis: Cost-effectiveness of the multicomponent Tobacco-Free Duo programme will be evaluated against the educational component of the same programme only. An incremental cost-effectiveness ratio (ICER) will be calculated in terms of the cost per case prevented using the trial primary outcome and within-trial payer costs. If the ICER is negative, an incremental net benefit ratio will be calculated. Robustness of the results will be assessed through one-way sensitivity analyses. The slope index of inequality will be computed to assess the potential impact of the Tobacco-free Duo programme on education-related inequalities in the onset of smoking and in adult smoking cessation, comparing the two trial arms.Ethics and dissemination: Ethical approval was obtained from the Regional Ethics Review Board, Umeå (registration number 2017/255-31). The Public Health Agency of Sweden commissioned the study. The findings will be disseminated internationally within academia and to national and local policy-makers.Trial registration number: ISRCTN52858080; Pre-results.

- Friends' and parents' tobacco use are strong predictors of tobacco uptake among adolescents, however the effectiveness of interventions based on public commitments and agreements to remain tobacco-free are not established. Here, we evaluated the effectiveness of the school-based Swedish program Tobacco-Free Duo (T-Duo) in preventing adolescents from initiating tobacco use (TOPAS study). T-Duo is a multi-component intervention witha formal agreement between a student and an adult partner to remain tobacco-free during the entire 3-year study period as core component. The standardized educational component of the same program was used as comparator (control). Primary outcome was the probability to “remain a non-user” of i) cigarettes and secondary outcomes ii) other types of tobacco at second (21-month) follow-up. Analysis was conducted according to Intention To Treat. In total 1776 adolescents (51% female) aged 12–13 in grade 7 from 34 participating high schools in Sweden were included at baseline in 2018, of which 1489 were retained after 21 months. The Risk Ratio (RR) of not having tried cigarettes 21-months after initiation of the intervention was 1.03(CI 0.98–1.08), Bayes Factor(BF) = 0.93, Absolute Risk Difference(ARD) = 3.1%. Similar associations were found for never smoked a whole cigarette and never use of other tobacco/nicotine products. There was a minimal reduction of tobacco use initiation among Swedish adolescents assigned to a multi-component intervention (T-Duo) compared to those assigned to standardized classroom education after 2 schoolyears. However, for most outcomes' findings were inconclusive and not reliably different from zero.

Topas - tobakspreventivt arbete i skolan. Slutrapport : en utvärdering av det ANDT-förebyggande programmet Tobaksfri duo
- 2022
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- I Sverige har tobaksförebyggande program med ungdomar som målgrupp under många år initierats, utvecklats och drivits av kommuner, regioner, och den ideella sektorn. Antalet vetenskapliga studier om tobaksförebyggande arbete i landet som publicerats i vetenskapliga tidskrifter är mycket få och har främst genomförts med en kvasiexperimentell design. Tobaksfri duo (T-Duo) har spridits i landet och önskemål har uttryckts om en utvärdering med metodik som ger högre evidensgrad jämfört med de studier som genomförts tidigare. Genom Topasprojektet har en sådan utvärdering av användningen av programmets kärnkomponenter möjliggjorts. Studien har genomförts av Umeå universitet och Karolinska Institutet på uppdrag av Folkhälsomyndigheten. Den hade en blandad design: 1) en klusterrandomiserad kontrollerad studie (CRCT) där skolor tilldelades programmet T-Duos sex kärnkomponenter eller en minimal komponent i form av Strukturerad undervisning, 2) en observationsstudie där programskolor jämfördes med skolor i en extern referensgrupp samt 3) en hälsoekonomisk utvärdering av programmets kostnadseffekt.Studiens övergripande syfte var att utvärdera effekterna och kostnaderna av programmet T-Duos sex kärnkomponenter genom att besvara följande specifika frågeställningar:Påverkas ungas tobaksdebut och tobaksanvändning av programmet? - d.v.s. är den förebyggande effekten större om man arbetar med programmet jämfört med en minimal komponent, alternativt ordinarie ANDT-undervisning i skolan?Påverkar deltagande i programmet vårdnadshavares tobaksbruk?Har graden av implementering av programmet betydelse för effekten?Är effekterna sådana att programkostnaderna är motiverade?Resultaten från studien visar att det fullständiga programmet T-Duo förknippas med en måttlig förebyggande effekt på högstadieelevers tobaksdebut (cirka 8 % större sannolikhet att förbli rökfria efter tre år), jämfört med om man enbart bedrev undervisning om tobak enligt programmet som ingick i Topas kontrollgrupp Undervisningsskolor (U-skolor). Resultaten kan dock ha påverkats av vissa systematiska fel, dels bortfall, dels beroende på självrapportering.Kontraktet som skrevs mellan ett barn och en vuxen 18 år eller äldre som barnet själv valde som vuxenpartner i T-Duo visade sig vara en effektiv komponent om kontraktet kunde upprätthållas under samtliga år. Komponenten innehåller tre delar kopplat till kontraktet, i) dels en möjlighet till stöd från en vuxen som barnet själv valt, att barnet ii) vid kontraktsskrivning gör ett åtagande inför andra om att man inte ska använda tobak under de kommande tre åren och slutligen iii) möjligheten för barnet att delta i utlottning av mindre priser och till rabatter (på till exempel skolfiket).Resultaten indikerade också att T-Duo kan påverka tobaksbruk på gruppnivå, det vill säga på skolnivå, på ett positivt sätt över tid. Med andra ord att alla elever på en skola som jobbade med T-Duo påverkades av programmet och inte bara de som deltog.Vad gällde vårdnadshavare (VH) i T-skolor sågs en möjlig effekt avseende tobaksstopp, det vill säga att de få deltagare som använde tobak i början av studien och som var kvar i slutet slutade använda tobak i större utsträckning än föräldrar i skolor lottade till enbart undervisningskomponenten. Dock måste resultaten tolkas med stor försiktighet på grund av det låga antalet VH som svarade på enkäten. Av denna anledning är det inte möjligt att säga om VH som tecknade kontrakt med sina barn hade större sannolikhet att förbli tobaksfria eller inte, eftersom andelen tobaksbrukare i gruppen som tecknade kontraktet med sina barn redan från början var mycket låg och betydligt lägre än bland resterande VH.Mycket få skolor hade implementerat programmet T-Duo helt enligt manualen för studien. Implementeringen var oftast måttlig, dvs att man hade genomfört mer än två kärnkomponenter enligt manualen, dock inte alla. Graden av implementering påverkade dock inte resultaten.I beräkningen av kostnadseffektivitet relaterades skillnaden i kostnader mellan T-skolor och U-skolor till den beräknade effekten i termer av hur många fler barn som förblev rökfria på grund av programmet. Det treåriga programmet kostade 785 kr per exponerat barn på T-skolorna och endast strukturerad undervisning kostade 491 kr per barn på U-skolorna. T-Duo kostade därmed 294 kr mer per barn jämfört med endast Strukturerad undervisning och kostnadseffektiviteten uppskattades till 5 066 kr för varje ytterligare barn som var rökfri i slutet på årskurs nio. Om effekten kvarstår fram till vuxen ålder representerar T-duo en mycket bra användning av resurserna i förhållande till framtida konsekvenser på hälsan som vuxen. Osäkerheten rörande programeffekten och om effekten kommer att bestå är avgörande för denna slutsats.

Tidskriftsartikel (refereegranskat)abstract
- Motivation: Despite signature of the 2005 Paris Declaration on Aid Effectiveness and subsequent adoption of the effective development cooperation (EDC) principles for better health cooperation, there is a gap in documenting the challenges to implement these commitments at country level. Sudan represents an interesting case study: the country adopted a local health compact in 2014, but for much of the time since the regime was under sanction. Sudan witnessed a revolution in 2018, followed by a counter-coup in 2021.Purpose: We aim to explore the evolution of Sudan health sector partners’ relationships, perspectives, and adherence to EDC principles of ownership, alignment, and harmonization, while accounting for underlying processes and context changes between 2015 and 2022.Methods and approach: We collected data through two rounds of interviews, in 2015 (16) and 2022 (8), with stakeholders within the Sudan Health Sector Partnership. We used the framework method for data analysis where responses are coded then sorted into themes.Findings: Prior to the 2019 revolution cooperation was progressive but restricted, with civil society marginalized and a dominating government. The principles, especially ownership, were misused and misaligned with national priorities driven by donors’ interests and conditions.The transitional (post-revolution) period witnessed partners’ openness and influx, but unstable leadership and subsequent changes in priorities led to wasted opportunities.Following the coup, donors adopted a no-contact policy towards the de facto government. Instead, the expectation was that civil society organizations would replace the government as the main implementers. Overall, limited coordination capacity and no sustainability measures were present throughout.Policy implications: Much of what was observed was down to the often complicated and difficult context of the governance of Sudan. That said, general issues arose including the government's ability to coordinate policy and implementation; the need for stable, legitimate arrangements; and the need to define the role of civil society and to empower civil society organizations. Within a complex and volatile context, revisiting partners’ commitments through joint compact reviews and transparent EDC progress monitoring is crucial.

Tidskriftsartikel (refereegranskat)abstract
- Sample selectivity is a recurrent problem in public health programmes and poses serious challenges to their evaluation. Traditional approaches to handle sample selection tend to rely on restrictive assumptions. The aim of this paper is to illustrate a copula-based selection model to handle sample selection in the evaluation of public health programmes. Motivated by a public health programme to promote physical activity in Leeds (England), we describe the assumptions underlying the copula selection, and its relative advantages compared with commonly used approaches to handle sample selection, such as inverse probability weighting and Heckman’s selection model. We illustrate the methods in the Leeds Let’s Get Active programme and show the implications of method choice for estimating the effect on individual’s physical activity. The programme was associated with increased physical activity overall, but the magnitude of its effect differed according to adjustment method. The copula selection model led to a similar effect to the Heckman’s approach but with relatively narrower 95% confidence intervals. These results remained relatively similar when different model specifications and alternative distributional assumptions were considered. The copula selection model can address important limitations of traditional approaches to address sample selection, such as the Heckman model, and should be considered in the evaluation of public health programmes, where sample selection is likely to be present.

Cost-effectiveness of Radiofrequency Denervation for Zygapophyseal Joint Pain
- 2021

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Chronic pain is a leading cause of disability. Radiofrequency denervation (RFD) is effective when performed according to guidelines for patients with correctly diagnosed zygapophyseal joint pain (ZJP). However, the cost-effectiveness of this method has not been fully explored.OBJECTIVE: The aim of this study was to analyze whether RFD is cost-effective for ZJP from a societal perspective.STUDY DESIGN: Cost effectiveness study based on an observational study.SETTING: An interventional pain management clinic in central Sweden.METHODS: Patients - This cost-effectiveness study was performed for all patients (n = 873) assessed between 2010 and 2016 at a specialized interventional pain clinic in Sweden. Those diagnosed with ZJP (n = 331, 37.9%) were treated with RFD and followed up for 1 year after the RFD. Using data collected from national registers, we determined the health care costs, medication costs, the patients' time and travel costs, and the patients' ability to work. The effects of RFD on quality-adjusted life years (QALY) and cost/QALY gained were calculated.RESULTS: On average, patients reported very low health-related quality of life (HRQoL; EQ-5D index: 0.212). After RFD, HRQoL increased significantly to 0.530 (P < 0.0001). Drug consumption and specialized health care consumption were reduced by 54% and 81%, respectively, and the cost/QALY gained from a societal perspective was 221,324 Swedish krona (USD ~26,008). The sensitivity analysis showed that the treatment was cost-effective in all scenarios evaluated, using the patients as their own controls. The cost/QALY gained from a health care perspective was 72,749 Swedish krona (USD ~8,548).LIMITATIONS: The results are based on data collected at one center. The results need to be compared with those from pain rehabilitation programs and should be confirmed using data from other centers.CONCLUSIONS: Patients referred for RFD in Sweden report extremely low HRQoL. HRQoL significantly increased following RFD in patients with ZJP. Medications and health care consumption decreased after RFD. RFD was cost-effective, and the sensitivity analysis yielded stable results in different scenarios. Therefore, RFD is a cost-effective treatment that meets the Swedish National Board of Health and Welfare criteria for a high priority treatment.TRIAL REGISTRATION: The study was registered at ClinicalTrials.gov (NCT01835704) with Protocol ID SE-Dnr-2012-446-31M-1. https://clinicaltrials.gov/ct2/show/NCT01835704.

Interventional pain management focused on zygapophysial joint pain : a health-economic evaluation
- 2023
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The pain-system is a central mechanism in our life. Chronic pain is one of the major causes of impaired health-related quality of life according to the World Health Organization’s “Global Burden of Disease”-studies. Zygapophysial joint pain has been shown to account for the pain in 30% - 50% of patients with chronic pain. There are several well-established, evidence-based methods to treat zygapophysial joint pain in the cervical and lumbar regions.This thesis originates from this and starts by exploring whether the treatment of zygapophysial joint pain can improve health-related quality of life. This thesis describes methods for the diagnosis and treatment of zygapophysial joint pain in the thoracic region that can be applied to the treatment of all pain-foci localized to the zygapophysial joints. I show that the health-related quality of life was significantly improved after treatment, and that the clinical methods used for treating thoracic pain were similar to the methods that have been established previously for cervical and lumbar pain.In order to better understand the patients’ experiences we performed qualitative interviews with patients who underwent diagnostic tests and treatments. The overall theme revealed by these interviews was that of empowerment, in which the patients were empowered by the process of diagnostic tests and treatments.The next question was whether the method was cost-effective or not. In the first cost-effectiveness analysis, the patients served as their own controls and we evaluated the results against the limits set by the Swedish national board of health and welfare. The results showed that it was cost-effective in the moderate to low range.Finally, we compared the treatment to the “gold standard” for pain management in Sweden; i.e.pain rehabilitation. We mimicked a randomized controlled trial by using propensity score weighting to compare 254 patients agains 15,357 patients registered in the Swedish National Register of Pain Rehabilitation. The results showed that interventional pain management was cost-effective in the moderate (12 months after treatment) to low (≥24 months after) range whereas pain rehabilitation was in the very high range (after 12 months) and became cost-effective in the high range after 24 months of treatment. Currently, interventional pain management accounts for just 2% of all specialized pain management procedures in Sweden. If this could be increased to 25%, it may be possible to save 106 million SEK annually, while simultaneously gain 14 quality adjusted life years of health. If an interventional pain assessment is performed early in the process, treatable patients could be directed toward interventional treatment and away from interdisciplinary pain management programs, with the potential for further reductions in costs.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: Diabetes mellitus (DM) is a serious public health issue that places a heavy financial, social, and health-related burden on individuals, families, and healthcare systems. Self-reported health-related quality of life (HRQoL) is extensively used for monitoring the general population's health conditions and measuring the effectiveness of interventions. Therefore, this study investigated HRQoL and associated factors among patients with type 2 DM at a primary healthcare center in Indonesia.Methods: A cross-sectional study was conducted in Klaten District, Central Java, Indonesia, from May 2019 to July 2019. In total, 260 patients with DM registered with National Health Insurance were interviewed. HRQoL was measured with the EuroQol Group's validated Bahasa Indonesia version of the EuroQoL 5-Dimension 5-Level (EQ-5D-5L) with the Indonesian value set. Multivariate regression models were used to identify factors influencing HRQoL.Results: Data from 24 patients were excluded due to incomplete information. Most participants were men (60.6%), were aged above 50 years (91.5%), had less than a senior high school education (75.0%), and were unemployed (85.6%). The most frequent health problems were reported for the pain/discomfort dimension (64.0%) followed by anxiety (28.4%), mobility (17.8%), usual activities (10.6%), and self-care (6.8%). The average EuroQoL 5-Dimension (EQ-5D) index score was 0.86 (95% confidence interval [CI], 0.83 to 0.88). In the multivariate ordinal regression model, a higher education level (coefficient, 0.08; 95% CI, 0.02 to 0.14) was a significant predictor of the EQ-5D-5L utility score.Conclusions: Patients with diabetes had poorer EQ-5D-5L utility values than the general population. DM patients experienced pain/discomfort and anxiety. There was a substantial positive relationship between education level and HRQoL.
