ECONOMIC EVALUATION STUDIES OF SELF-MANAGEMENT INTERVENTIONS IN CHRONIC DISEASES: A SYSTEMATIC REVIEW

Cost-Effectiveness of an Individualised Management Program after Stroke: A Trial-Based Economic Evaluation

INTRODUCTION

Evidence on the cost-effectiveness of comprehensive post-stroke programs is limited. We assessed the cost-effectiveness of an individualised management program (IMP) for stroke or transient ischaemic attack (TIA).

METHODS

A cost-utility analysis alongside a randomised controlled trial with a 24-month follow-up, from both societal and health system perspectives, was conducted. Adults with stroke/TIA discharged from hospitals were randomised by primary care practice to receive either usual care (UC) or an IMP in addition to UC (intervention). An IMP included stroke-specific nurse-led education and a specialist review of care plans at baseline, 3 months, and 12 months, and telephone reviews by nurses at 6 months and 18 months. Costs were expressed in 2021 Australian dollars (AUD). Costs and quality-adjusted life years (QALYs) beyond 12 months were discounted by 5%. The probability of cost-effectiveness of the intervention was determined by quantifying 10,000 bootstrapped iterations of incremental costs and QALYs below the threshold of AUD 50,000/QALY.

RESULTS

Among the 502 participants (65% male, median age 69 years), 251 (50%) were in the intervention group. From a health system perspective, the incremental cost per QALY gained was AUD 53,175 in the intervention compared to the UC group, and the intervention was cost-effective in 46.7% of iterations. From a societal perspective, the intervention was dominant in 52.7% of iterations, with mean per-person costs of AUD 49,045 and 1.352 QALYs compared to mean per-person costs of AUD 51,394 and 1.324 QALYs in the UC group. The probability of the cost-effectiveness of the intervention, from a societal perspective, was 60.5%.

CONCLUSIONS

Care for people with stroke/TIA using an IMP was cost-effective from a societal perspective over 24 months. Economic evaluations of prevention programs need sufficient time horizons and consideration of costs beyond direct healthcare utilisation to demonstrate their value to society.

Cost-Effectiveness of a Government Policy to Incentivise Chronic Disease Management following Stroke: A Modelling Study

INTRODUCTION

Little is known about the cost-effectiveness of government policies that support primary care physicians to provide comprehensive chronic disease management (CDM). This paper aimed to estimate the potential cost-effectiveness of CDM policies over a lifetime for long-time survivors of stroke.

METHODS

A Markov model, using three health states (stable, hospitalised, dead), was developed to simulate the costs and benefits of CDM policies over 30 years (with 1-year cycles). Transition probabilities and costs from a health system perspective were obtained from the linkage of data between the Australian Stroke Clinical Registry (cohort n = 12,368, 42% female, median age 70 years, 45% had CDM claims) and government-held hospital, Medicare, and pharmaceutical claims datasets. Quality-adjusted life years (QALYs) were obtained from a comparable cohort (n = 512, 34% female, median age 69.6 years, 52% had CDM claims) linked with Medicare claims and death data. A 3% discount rate was applied to costs in Australian dollars (AUD, 2016) and QALYs beyond 12 months. Probabilistic sensitivity analyses were used to understand uncertainty.

RESULTS

Per-person average total lifetime costs were AUD 142,939 and 8.97 QALYs for those with a claim, and AUD 103,889 and 8.98 QALYs for those without a claim. This indicates that these CDM policies were costlier without improving QALYs. The probability of cost-effectiveness of CDM policies was 26.1%, at a willingness-to-pay threshold of AUD 50,000/QALY.

CONCLUSION

CDM policies, designed to encourage comprehensive care, are unlikely to be cost-effective for stroke compared to care without CDM. Further research to understand how to deliver such care cost-effectively is needed.

Chronic pain self-management interventions in primary care - does it make any difference? A qualitative study

BACKGROUND

Total recovery from chronic pain is difficult. It is therefore important for those who are suffering from chronic pain to find ways to self-manage their pain in daily life. Several chronic pain self-management interventions have been established, but more knowledge is needed to find out what and how it works. This study aimed to explore how the participants in two chronic pain self-management interventions in primary health care experienced the different components of the interventions, and whether the interventions induced any positive changes in the participants' everyday lives.

METHODS

A qualitative study nested within a randomized controlled study using semi-structured individual face-to-face interviews with 17 informants were conducted three months after the interventions. The data were analysed thematically using Systematic Text Condensation.

RESULTS

The main finding was that the informants, from both interventions, self-managed their chronic pain differently in a positive way after they had participated in the self-management interventions. The participants gained new insight from lectures, learning from peers by sharing experiences and belonging to a group, and by recognizing the importance of being physically active.

CONCLUSION

This study shows that chronic pain self-management interventions consisting of components that learn the participants about chronic pain and include physical activity in a socially supportive environment, may contribute to a positive change in the lives of people living with chronic pain.

Using the WHO-INTEGRATE evidence-to-decision framework to develop recommendations for induction of labour

BACKGROUND

In 2019, WHO prioritized updating recommendations relating to three labour induction topics: labour induction at or beyond term, mechanical methods for labour induction, and outpatient labour induction. As part of this process, we aimed to review the evidence addressing factors beyond clinical effectiveness (values, human rights and sociocultural acceptability, health equity, and economic and feasibility considerations) to inform WHO Guideline Development Group decision-making using the WHO-INTEGRATE evidence-to-decision framework, and to reflect on how methods for identifying, synthesizing and integrating this evidence could be improved.

METHODS

We adapted the framework to consider the key criteria and sub-criteria relevant to our intervention. We searched for qualitative and other evidence across a variety of sources and mapped the eligible evidence to country income setting and perspective. Eligibility assessment and quality appraisal of qualitative evidence syntheses was undertaken using a two-step process informed by the ENTREQ statement. We adopted an iterative approach to interpret the evidence and provided both summary and detailed findings to the decision-makers. We also undertook a review to reflect on opportunities to improve the process of applying the framework and identifying the evidence.

RESULTS

Using the WHO-INTEGRATE framework allowed us to explore health rights and equity in a systematic and transparent way. We identified a lack of qualitative and other evidence from low- and middle-income settings and in populations that are most impacted by structural inequities or traditionally excluded from research. Our process review highlighted opportunities for future improvement, including adopting more systematic evidence mapping methods and working with social science researchers to strengthen theoretical understanding, methods and interpretation of the evidence.

CONCLUSIONS

Using the WHO-INTEGRATE evidence-to-decision framework to inform decision-making in a global guideline for induction of labour, we identified both challenges and opportunities relating to the lack of evidence in populations and settings of need and interest; the theoretical approach informing the development and application of WHO-INTEGRATE; and interpretation of the evidence. We hope these insights will be useful for primary researchers as well as the evidence synthesis and health decision-making communities, and ultimately contribute to a reduction in health inequities.

Patient engagement strategies for adults with chronic conditions: an evidence map

BACKGROUND

Patient and family engagement (PFE) has been defined as a partnership between patients, families, and health care providers to achieve positive health care outcomes. There is evidence that PFE is critical to improving outcomes. We sought to systematically identify and map the evidence on PFE strategies for adults with chronic conditions and identify areas needing more research.

METHODS

We searched PubMed, CINAHL, EMBASE, and Cochrane, January 2015 to September 2021 for systematic reviews on strategies for engaging patients with chronic conditions and their caregivers. From each review, we abstracted search dates, number and type of studies, populations, interventions, and outcomes. PFE strategies were categorized into direct patient care, health system, and community-policy level strategies. We found few systematic reviews on strategies at the health system, and none at the community-policy level. In view of this, we also searched for original studies that focused on PFE strategies at those two levels and reviewed the PFE strategies used and study findings.

RESULTS

We found 131 reviews of direct patient care strategies, 5 reviews of health system strategies, and no reviews of community-policy strategies. Four original studies addressed PFE at the health system or community-policy levels. Most direct patient care reviews focused on self-management support (SMS) (n = 85) and shared decision-making (SDM) (n = 43). Forty-nine reviews reported positive effects, 35 reported potential benefits, 37 reported unclear benefits, and 4 reported no benefits. Health system level strategies mainly involved patients and caregivers serving on advisory councils. PFE strategies with the strongest evidence focused on SMS particularly for patients with diabetes. Many SDM reviews reported potential benefits especially for patients with cancer.

DISCUSSION

Much more evidence exists on the effects of direct patient care strategies on PFE than on the effects of health system or community-policy strategies. Most reviews indicated that direct patient care strategies had positive effects or potential benefits. A limitation of this evidence map is that due to its focus on reviews, which were plentiful, it did not capture details of individual interventions. Nevertheless, this evidence map should help to focus attention on gaps that require more research in efforts to improve PFE.

The cost-effectiveness of tranexamic acid for treatment of postpartum hemorrhage: A systematic review

BACKGROUND

Postpartum hemorrhage (PPH) is responsible for nearly one quarter of maternal deaths. A 2017 multicountry trial found that incorporating tranexamic acid (TXA) into the PPH management package was effective in reducing maternal death due to bleeding.

OBJECTIVE

To systematically review studies assessing the cost-effectiveness of tranexamic acid for PPH treatment.

SEARCH STRATEGY

Nine databases were searched using variations of keywords 'tranexamic acid', 'postpartum hemorrhage' and 'cost effectiveness'.

SELECTION CRITERIA

Eligible studies were any type of economic or effectiveness evaluation studies on tranexamic acid for treating women with PPH.

DATA COLLECTION AND ANALYSIS

Two reviewers independently screened citations and extracted data on cost effectiveness measures. Quality was assessed using the Consensus on Health Economic Criteria list.

MAIN RESULTS

Four studies were included, of which two were abstracts. Three studies concluded that early administration of TXA was cost-saving or cost-effective. One abstract reported TXA was not cost-effective in the USA unless the probability of death due to hemorrhage is higher.

CONCLUSION

Available evidence (four studies in three countries) suggests that this life-saving intervention may be below willingness to pay thresholds (cost-effective) or cost saving. Further studies conducted in different populations and settings are needed to inform health policy decision-making to reduce PPH-associated morbidity and mortality.

Cochrane reviews of educational and self-management interventions to guide nursing practice: A review

BACKGROUND

The burden of chronic disease on healthcare services worldwide continues to grow, and the increased development of educational interventions which help patients to better manage their own condition is evident internationally.

OBJECTIVES

This paper reports on findings of an updated review of Cochrane systematic reviews of interventions designed to improve patients' knowledge and skills to manage chronic disease, with particular reference to nursing contribution and practice.

METHODS

A broad search strategy was used to search the Cochrane Database of Systematic Reviews to identify reviews of patient education, self-management, and self-care studies. Two reviewers independently assessed eligibility for inclusion and extracted data from the reviews.

FINDINGS

From a total of 882 reviews, 63 met the inclusion criteria, and 900 studies were identified. Most (68%, n = 43) of the 63 reviews were judged by Cochrane reviewers to provide inadequate evidence of the effectiveness of the interventions reviewed. Information on the profession of the person delivering the intervention was often not available, although 78% (n = 49) of reviews mentioned that nurses were involved in a proportion of studies delivering interventions either independently or as part of a multi-professional team.

CONCLUSION

Educational programmes have definite benefits for patients suffering from asthma, chronic obstructive pulmonary disorder and stroke, and are promising in areas such as diabetes, epilepsy, cancer care, and mental health. However, it still is not clear what the active ingredients of many successful interventions are. Further research is needed to establish the impact of technology on programme delivery, and to develop programmes tailored for patients with multiple health problems.

A trial-based economic evaluation of the Restore4Stroke self-management intervention compared to an education-based intervention for stroke patients and their partners

BACKGROUND

Since stroke survivors are increasingly responsible for managing stroke-related changes in their own health and lifestyle, self-management skills are required. In a recent randomised controlled trial a self-management intervention based on proactive coping action planning (SMI) in comparison with an education-based intervention (EDU) in stroke patients was investigated. However, no relevant treatment effects on the Utrecht Proactive Coping Competence scale (UPCC) and the Utrecht Scale for Evaluation of Rehabilitation Participation (USER-Participation) were found. The current study is a trial-based economic evaluation from a societal perspective comparing the same interventions (SMI versus EDU).

METHODS

UPCC, USER-Participation and EuroQol (EQ-5D-3 L) and costs were measured at baseline, three, six and twelve months after treatment. For the cost-effectiveness analyses, incremental cost effectiveness ratios (ICERs) were calculated for UPCC and USER-Participation. For the cost-utility analyses the incremental cost utility ratio (ICUR) was expressed in cost per Quality Adjusted Life Years (QALYs). Outcomes were tested by means of AN(C)OVA analyses and costs differences by means of bootstrapping. Bootstrapping, sensitivity analyses and a subgroup analysis were performed to test the robustness of the findings.

RESULTS

One hundred thirteen stroke patients were included in this study. The mean differences in USER-Participation scores (95%CI:-13.08,-1.61, p-value = .013) were significant different between the two groups, this does not account for UPCC scores (95%CI:-.267, .113, p-value = not significant) and QALYs (p-value = not significant) at 12 months. The average total societal costs were not significantly different (95%CI:€-3380,€7099) for SMI (€17,333) in comparison with EDU (€15,520). Cost-effectiveness analyses showed a mean ICER of 26,514 for the UPCC and 346 for the USER-Participation. Cost-utility analysis resulted in an ICUR of €44,688 per QALY. Assuming a willingness to pay (WTP) threshold of €50,000 per QALY, the probability that SMI will be cost-effective is 52%. Sensitivity analyses and subgroup analysis showed the robustness of the results.

CONCLUSIONS

SMI is probably not a cost-effective alternative in comparison with EDU. Based on the current results, the value of implementing SMI for a stroke population is debatable. We recommend further exploration of the potential cost-effectiveness of stroke-specific self-management interventions focusing on different underlying mechanisms and using different control treatments.

COST-EFFECTIVENESS OF INTERVENTIONS BASED ON PHYSICAL ACTIVITY IN THE TREATMENT OF CHRONIC CONDITIONS: A SYSTEMATIC LITERATURE REVIEW

Objectives:

The aim of this study is to review evidence on the cost-effectiveness of exercise-based interventions in the treatment of chronic conditions a decade after the publication of Roine et al. in 2009 (Roine E, Roine RP, Räsänen P, et al. Int J Technol Assess Health Care. 2009;25:427–454).

Methods:

We carried out a review of published articles in PUBMED and JSTOR between January 1, 2008, and December 31, 2016. Full economic evaluations of exercise programs targeting patients with a chronic condition were eligible for inclusion. Data on program, design, and economic characteristics were extracted using a predefined extraction form. The quality of the economic evaluations was appraised using the adjusted Consensus Health Economic Criteria List.

Results:

A total of 426 articles were identified and thirty-seven studies were selected. Eleven studies dealt with musculoskeletal and rheumatologic disorders, ten with cardiovascular diseases, six with neurological disorders, three with mental illnesses, three with cancers, and four with diabetes, respiratory diseases, or pelvic organ prolapse. In total, 60 percent of exercise programs were dominant or cost-effective. For musculoskeletal and rheumatologic disorders, 72 percent of programs were dominant or cost-effective while this was the case for 57 percent of programs for cardiovascular diseases using a nonsurgical comparator.

Conclusions:

There is clear evidence in favor of exercise-based programs for the treatment of musculoskeletal and rheumatologic disorders and, to a lesser extent, for the treatment of cardiovascular diseases. More research is needed to evaluate the cost-effectiveness of physical activity in the treatment of neurological disorders, mental illnesses, cancers, respiratory diseases, and diabetes/obesity.
