The web-based Pleasure&Pregnancy programme in the treatment of unexplained infertility: a randomized controlled trial

STUDY QUESTION

Does offering the Pleasure&Pregnancy (P&P) programme rather than expectant management improve naturally conceived ongoing pregnancy rates in couples diagnosed with unexplained infertility?

SUMMARY ANSWER

The P&P programme had no effect on the ongoing pregnancy rates of couples with unexplained infertility.

WHAT IS KNOWN ALREADY

Underpowered studies suggested that face-to-face interventions targeting sexual health may increase pregnancy rates. The impact of an eHealth sexual health programme had yet to be evaluated by a large randomized controlled trial.

STUDY DESIGN, SIZE, DURATION

This is a nationwide multi-centre, unblinded, randomized controlled superiority trial (web-based randomization programme, 1:1 allocation ratio). This RCT intended to recruit 1164 couples within 3 years but was put on hold after having included 700 couples over 5 years (2016-2021). The web-based P&P programme contains psychosexual information and couple communication, mindfulness and sensate focus exercises aiming to help maintain or improve sexual health, mainly pleasure, and hence increase pregnancy rates. The P&P programme additionally offers information on the biology of conception and enables couples to interact online with peers and via email with coaches.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Heterosexual couples with unexplained infertility and a Hunault-prognosis of at least 30% chance of naturally conceiving a live-born child within 12 months were included, after their diagnostic work-up in 41 Dutch secondary and tertiary fertility centres. The primary outcome was an ongoing pregnancy, defined as a viable intrauterine pregnancy of at least 12 weeks duration confirmed by an ultrasound scan, conceived naturally within 6 months after randomization. Secondary outcomes were time to pregnancy, live birth, sexual health, and personal and relational well-being at baseline and after 3 and 6 months. The primary analyses were according to intention-to-treat principles. We calculated relative risks (RRs, pregnancy rates) and a risk difference (RD, pregnancy rates), Kaplan-Meier survival curves (live birth over time), and time, group, and interactive effects with mixed models analyses (sexual health and well-being).

MAIN RESULTS AND THE ROLE OF CHANCE

Totals of 352 (one withdrawal) and 348 (three withdrawals) couples were allocated to, respectively the P&P group and the expectant management group. Web-based tracking of the intervention group showed a high attrition rate (57% of couples) and limited engagement (i.e. median of 16 visits and 33 min total visitation time per couple). Intention-to-treat analyses showed that 19.4% (n = 68/351) of the P&P group and 22.6% (n = 78/345) of the expectant management group achieved a naturally conceived ongoing pregnancy (RR = 0.86; 95% CI = 0.64-1.15, RD = -3.24%; 95% CI -9.28 to 2.81). The time to pregnancy did not differ between the groups (Log rank = 0.23). Live birth occurred in 18.8% (n = 66/351) of the couples of the P&P group and 22.3% (n = 77/345) of the couples of the expectant management group (RR = 0.84; 95% CI = 0.63-1.1). Intercourse frequency decreased equally over time in both groups. Sexual pleasure, orgasm, and satisfaction of women of the P&P group improved while these outcomes remained stable in the expectant management group. Male orgasm, intercourse satisfaction, and overall satisfaction decreased over time with no differences between groups. The intervention did not affect personal and relational well-being. Non-compliance by prematurely starting medically assisted reproduction, and clinical loss to follow-up were, respectively, 15.1% and 1.4% for the complete study population. Per protocol analysis for the primary outcome did not indicate a difference between the groups. Comparing the most engaged users with the expectant management group added that coital frequency decreased less, and that male sexual desire improved in the intervention group.

LIMITATIONS, REASONS FOR CAUTION

The intended sample size of 1164 was not reached because of a slow recruitment rate. The achieved sample size was, however, large enough to exclude an improvement of more than 8% of the P&P programme on our primary outcome.

WIDER IMPLICATIONS OF THE FINDINGS

The P&P programme should not be offered to increase natural pregnancy rates but may be considered to improve sexual health. The attrition from and limited engagement with the P&P programme is in line with research on other eHealth programmes and underlines the importance of a user experience study.

Group interventions for people with primary progressive aphasia and their care partners: Considerations for clinical practice

Primary progressive aphasia (PPA) describes a group of language-led dementias. Speech and language therapy is the main available intervention for people with PPA. Despite best practice recommendations for speech and language therapy to include access to group therapies (Volkmer et al, 2023a), research evidence to date has predominantly focused on delivery in individual sessions. The aim of this study was to gather the collective intelligence of expert speech and language therapists/pathologists delivering group therapy for people with PPA to synthesize guidance for clinicians. This paper describes a qualitative study using narrative synthesis methods. Data were collected using the Template for Intervention Description and Replication - TIDiER. Eight respondents described a total of 17 different groups. Respondents worked across healthcare, research clinics and third sector organizations in Australia, Canada, Spain, the USA and the UK. For the purposes of analysis, groups were divided into two main types: (1) groups delivering specific therapy interventions; and (2) groups providing broader opportunities for conversational practice and support. This initial synthesis of the current state of the art in PPA therapy groups highlights several important considerations around candidacy, content and ecological validity of delivering group intervention for people with PPA.

The Effectiveness and Characteristics of Communication Partner Training Programs for Families of People With Dementia: A Systematic Review

BACKGROUND AND OBJECTIVES

Communication partner training (CPT) is essential in dementia care. Despite families being the largest group of community carers, previous reviews primarily focused on formal carers. This study aimed to understand the characteristics and effectiveness of CPT for families of people with dementia.

RESEARCH DESIGN AND METHODS

The systematic review included intervention/protocol studies on dementia CPT for families, excluding formal carers and programs not focused on communication. CINAHL, PsycINFO, SpeechBITE, Medline, SCOPUS, and Embase were searched between November 30 and December 6, 2021. After deduplication, 3,172 records were screened. Quality assessment used JBI Critical Appraisal tools and the Mixed Methods Appraisal Tool. Data synthesis utilized three reporting tools, the International Classification of Functioning, Disability, and Health, and content analysis.

RESULTS

Of 30 studies (27 programs), there were 10 quasi-experimental, 5 RCTs, 4 mixed methods, 4 case studies, 4 qualitative, and 2 protocols. Studies were published between 1998 and 2021 and included 671 family members. Characteristics varied with 7/27 programs including consumers during creation and one program including telehealth. One study included all reporting tool criteria. Programs typically used 4 intervention functions, with 12/27 programs addressing 3 behavior change areas. 33/74 outcome measures targeted the "Environment" of the person with dementia. Studies showed positive improvements in communication skills and knowledge, with mixed results on behavior/psychosocial outcomes. Qualitative results identified improvements in conversation and attitudes.

DISCUSSION AND IMPLICATIONS

CPT for families improves communication outcomes, however, quality of studies varied significantly. Future research should address gaps in telehealth, consumer involvement, and intervention descriptions.

What contextual features affect the outcome and sustainability of therapeutic patient education interventions?

BACKGROUND

Therapeutic patient education interventions are influenced by contextual factors. Therefore, describing the context is crucial to understanding how it can affect therapeutic patient education interventions and contribute to outcomes. We aimed to identify the contextual features that may affect the outcome and sustainability of therapeutic patient education interventions from a healthcare professional perspective.

METHODS

Semi-structured individual interviews were conducted with healthcare professionals involved in 14 therapeutic patient education interventions covering different chronic conditions (e.g., kidney and cardiovascular diseases, chronic pain, diabetes, obesity). Interviews were recorded and fully transcribed. We followed a general inductive approach to identify themes from healthcare professionals' discourse to properly capture their perception.

RESULTS

Saturation was achieved with 28 interviews with 20 nurses, 6 dieticians, one physiotherapist and one psychologist. The average therapeutic patient education experience was 7 years. Identified contextual features clustered in 5 main themes: 1) conditions for the development of the intervention (genesis of the program: Who and what prompted it?; supports; content development; legislative framework); 2) integration of the program (in the healthcare pathway or the environment, relationship with the institution or local environment); 3) teamwork cohesion, interaction and integration with the environment (exchanges, cohesion of the team); 4) sustainability of the program; and 5) patient and healthcare professional contextual factors.

CONCLUSION

New insights into contextual features that may be involved in therapeutic patient education interventions are represented in a framework based on the Medical Research Council evaluation framework. These features need to be addressed in studies of therapeutic patient education interventions and could help healthcare professionals build more effective interventions within the context. However, describing a list of elements of the context is not enough; analyses should also focus on how the contextual elements might affect an intervention and how they interact.

Alliance of Randomized Trials of Medicine vs Metabolic Surgery in Type 2 Diabetes (ARMMS-T2D): Study rationale, design, and methods

AIMS

Long-term data from randomized clinical trials comparing metabolic (bariatric) surgery versus a medical/lifestyle intervention for treatment of patients with obesity/overweight and type 2 diabetes (T2D) are lacking. The Alliance of Randomized Trials of Medicine vs Metabolic Surgery in Type 2 Diabetes (ARMMS-T2D) is a consortium of four randomized trials designed to compare long-term efficacy and safety of surgery versus medical/lifestyle therapy on diabetes control and clinical outcomes.

MATERIALS AND METHODS

Patients with T2D and body mass index (BMI) of 27-45 kg/m² who were previously randomized to metabolic surgery (Roux-en-Y gastric bypass, adjustable gastric band, or sleeve gastrectomy) versus medical/lifestyle intervention in the STAMPEDE, SLIMM-T2D, TRIABETES, or CROSSROADS trials have been enrolled in ARMMS-T2D for observational follow-up. The primary outcome is change in glycated haemoglobin after a minimum 7 years of follow-up, with additional analyses to determine rates of diabetes remission and relapse, as well as cardiovascular and renal endpoints.

RESULTS

In total, 302 patients (192 surgical, 110 medical/lifestyle) previously randomized in the four parent studies were eligible for participation in the ARMMS-T2D observational study. Participant demographics were 71% white, 27% African-American and 68% female. At baseline: age, 50 ± 8 years; BMI, 36.5 ± 3.5 kg/m² ; duration of diabetes, 8.8 ± 5.6 years; glycated haemoglobin, 8.6% ± 1.6%; and fasting glucose, 168 ± 64 mg/dl. More than 35% of patients had a BMI <35 kg/m² .

CONCLUSIONS

ARMMS-T2D will provide the largest body of long-term, level 1 evidence to inform clinical decision-making regarding the comparative durability, efficacy and safety of metabolic surgery relative to a medical/lifestyle intervention among patients with T2D, including those with milder class I obesity or mere overweight.

Age-Appropriate Advance Care Planning in Children Diagnosed with a Life-Limiting Condition: A Systematic Review

Pediatric advance care planning (pACP) is an important strategy to support patient-centered care. It is known to be difficult, yet paramount, to involve the child in pACP while adjusting treatment to age and the corresponding stage of development. This systematic review was aimed to evaluate the age appropriateness of pACP interventions by assessing their characteristics, content, and evidence. CINAHL, Embase and MEDLINE were searched from 1 January 1998 to 31 August 2020 in order to identify peer-reviewed articles containing strategies and tools to facilitate pACP in both children (0–18 years) with life-limiting conditions and their families. An assessment of quality was performed using Cochrane tools and COREQ. The full protocol is available as PROSPERO CRD42020152243. Thirty-one articles describing 18 unique pACP tools were included. Most tools were developed for adolescents and young adults. In most cases, the interventions tried to assess the child’s and family’s preferences concerning their current and future hopes, wishes, and goals of the care. This was aimed to enhance communication about these preferences between children, their families, and health-care providers and to improve engagement in pACP. The relevance of an age-appropriate approach was mentioned in most articles, but this was mainly implicit. Seven articles implemented age-appropriate elements. Six factors influencing age appropriateness were identified. Tools to support pACP integrated age-appropriate elements to a very limited extent. They mainly focused on adolescents. The involvement of children of all ages may need a more comprehensive approach.

Effectiveness of a multifaceted intervention to improve interpersonal skills of physicians in medical consultations (EPECREM): protocol for a randomised controlled trial

INTRODUCTION

Interpersonal skills, encompassing communication and empathy, are key components of effective medical consultations. Although many organisations have implemented structured training programmes, limited evidence exists on their effectiveness in improving physician interpersonal skills. This study aims to evaluate the effectiveness of a standardised, multifaceted, interpersonal skills development programme for hospital physicians.

METHODS AND ANALYSIS

This study is a prospective, randomised (with a 1:1 allocation ratio), controlled, open-label, two parallel arm, superiority trial conducted at a single university hospital. Physicians will be randomised to receive either a multifaceted training programme or no intervention. The experimental intervention combines two 4-hour training sessions, dissemination of interactive educational materials, review of video-recorded consultations and individual feedback. The primary outcome measure is the overall 4-Habits Coding Scheme score assessed by two independent raters blinded to the study arm, based on video-recorded consultations, before and after intervention. The secondary outcomes include patient satisfaction, therapeutic alliance, physician self-actualisation and the length of medical consultation.

ETHICS AND DISSEMINATION

The study protocol was approved on 21 October 2020 by the CECIC Rhône-Alpes Auvergne, Clermont-Ferrand, France (IRB 5891). All participants will provide written informed consent. Efforts will be made to release the primary results within 6 to 9 months of study completion, regardless of whether they confirm or deny the research hypothesis.

Digital interventions in mental health: evidence syntheses and economic modelling

BACKGROUND

Economic evaluations provide evidence on whether or not digital interventions offer value for money, based on their costs and outcomes relative to the costs and outcomes of alternatives.

OBJECTIVES

(1) Evaluate and summarise published economic studies about digital interventions across different technologies, therapies, comparators and mental health conditions; (2) synthesise clinical evidence about digital interventions for an exemplar mental health condition; (3) construct an economic model for the same exemplar mental health condition using the previously synthesised clinical evidence; and (4) consult with stakeholders about how they understand and assess the value of digital interventions.

METHODS

We completed four work packages: (1) a systematic review and quality assessment of economic studies about digital interventions; (2) a systematic review and network meta-analysis of randomised controlled trials on digital interventions for generalised anxiety disorder; (3) an economic model and value-of-information analysis on digital interventions for generalised anxiety disorder; and (4) a series of knowledge exchange face-to-face and digital seminars with stakeholders.

RESULTS

In work package 1, we reviewed 76 economic evaluations: 11 economic models and 65 within-trial analyses. Although the results of the studies are not directly comparable because they used different methods, the overall picture suggests that digital interventions are likely to be cost-effective, compared with no intervention and non-therapeutic controls, whereas the value of digital interventions compared with face-to-face therapy or printed manuals is unclear. In work package 2, we carried out two network meta-analyses of 20 randomised controlled trials of digital interventions for generalised anxiety disorder with a total of 2350 participants. The results were used to inform our economic model, but when considered on their own they were inconclusive because of the very wide confidence intervals. In work package 3, our decision-analytic model found that digital interventions for generalised anxiety disorder were associated with lower net monetary benefit than medication and face-to-face therapy, but greater net monetary benefit than non-therapeutic controls and no intervention. Value for money was driven by clinical outcomes rather than by intervention costs, and a value-of-information analysis suggested that uncertainty in the treatment effect had the greatest value (£12.9B). In work package 4, stakeholders identified several areas of benefits and costs of digital interventions that are important to them, including safety, sustainability and reducing waiting times. Four factors may influence their decisions to use digital interventions, other than costs and outcomes: increasing patient choice, reaching underserved populations, enabling continuous care and accepting the 'inevitability of going digital'.

LIMITATIONS

There was substantial uncertainty around effect estimates of digital interventions compared with alternatives. This uncertainty was driven by the small number of studies informing most comparisons, the small samples in some of these studies and the studies' high risk of bias.

CONCLUSIONS

Digital interventions may offer good value for money as an alternative to 'doing nothing' or 'doing something non-therapeutic' (e.g. monitoring or having a general discussion), but their added value compared with medication, face-to-face therapy and printed manuals is uncertain. Clinical outcomes rather than intervention costs drive 'value for money'.

FUTURE WORK

There is a need to develop digital interventions that are more effective, rather than just cheaper, than their alternatives.

A systematic review of language and communication intervention research delivered in groups to older adults living in care homes

BACKGROUND

The communication skills of older adults living in care homes is an underexplored topic. Ageing can lead to reduced communication ability and activity; and in the care home environment there may also be fewer communication opportunities. This situation is likely to negatively impact well-being. Previous reviews have found evidence of the effectiveness of behavioural interventions in increasing well-being, but no systematic review to date has focused specifically on the evidence base for group language and communication interventions in this population.

AIMS

To identify and evaluate the evidence for behavioural interventions with older adults, delivered in groups in care homes, that specifically included a language or communication activity. To explore the impact of such intervention on the specific domains of language, communication and social interaction. To determine whether behavioural mechanisms of action can be identified.

METHODS & PROCEDURES

Embase, Medline, Ovid Nursing database, Psych info and CINAHL complete were searched and produced 158 records for screening, of which 22 remained for review. In order to identify and evaluate the quality of the evidence base presented the following research questions were posed: What research has been conducted in this area? What is the methodological quality of the studies identified? How complete is the intervention reporting? How was change measured in the domains of language, communication and social interaction? Is there evidence of efficacy, indicated by statistically significant improvement, in these domains? How did the interventions work? Synthesis tools employed included the PEDro-P Scale, the TIDieR checklist and the ITAX.

MAIN CONTRIBUTION

A total of 22 studies met the criteria for review. One study used solely language or communication interventions, but the remaining 21 studies used behavioural interventions which incorporated language and communication activities to varying degrees. Studies fell into four broad intervention types: reminiscence or life review; cognitive stimulation; narrative or storytelling; and multi-modality group communication. The majority of studies were of fair methodological quality, with a moderate level of detail provided in treatment reporting. Statistically significant improvement was reported by authors in all four intervention types and across language, communication and social domains. Social interaction, social support and behavioural skills were the most consistent mechanisms of action in the reviewed behavioural interventions.

CONCLUSIONS & IMPLICATIONS

Despite limitations in the evidence base, there are important positive signs for the beneficial effects of supporting language and communication in care homes. Blinding of assessors, and the accuracy and accessibility of statistical reporting are important areas to address in order to improve the quality of the evidence base.

WHAT THIS PAPER ADDS

Ageing can lead to reduced communication ability and activity, and in the care home setting there may also be fewer communication opportunities. This situation is likely to negatively impact well-being. Previous reviews have found evidence of the effectiveness of behavioural interventions in increasing well-being. The communication skills of older adults living in care homes is an underexplored topic. No systematic review to date has focused specifically on the evidence base for group language and communication interventions in this population. This review reveals important positive signs for the beneficial effects of supporting language and communication in care homes. Social interaction, social support, and behavioural skills were the most consistent mechanisms of action in the reviewed behavioural interventions.

Tailored patient therapeutic educational interventions: A patient-centred communication model

Background

Tailoring therapeutic education consists of adapting the intervention to patients' needs with the expectation that this individualization will improve the results of the intervention. Communication is the basis for any individualization process. To our knowledge, there is no guide or structured advice to help healthcare providers (HCPs) tailor patient education interventions.

Objectives

We used a data‐driven qualitative analysis to (1) investigate the reasons why HCPs tailor their educational interventions and (2) identify how this tailoring is effectively conducted. The perspective aimed to better understand how to individualize therapeutic patient education and to disentangle the different elements to set up studies to investigate the mechanisms and effects of individualization.

Design

Individual semistructured interviews with 28 HCPs involved in patient education were conducted. The present study complied with the COREQ criteria.

Results

Why individualization is necessary: participants outlined that the person must be thought of as unique and that therapeutic education should be adapted to the patient's personality and cognitive abilities. The first step in the individualization process was formalized by an initial patient assessment. Several informal practices were identified: if needed, giving an individual time or involving a specific professional; eliciting individual objectives; reinforcing the relationship by avoiding asymmetrical posture; focusing on patients' concerns; leading sessions in pairs; and making the patient the actor of decisions.

Conclusion

From our thematic data analysis, a model for tailoring patient education interventions based on the Haes and Bensing medical communication framework is proposed. The present work paves the way for evaluation, then generation of recommendations and finally implementation of training for individualization in educational interventions.

Short Informative

Tailoring in therapeutic education consists of an adaptation to patients' needs. Communication is the basis for any individualization process. There is no model of patient‐centred communication in educational interventions. From semistructured interviews with HCPs, we propose a patient‐centred communication model for tailoring patient education intervention.

Effectiveness of caregiver non-pharmacological interventions for behavioural and psychological symptoms of dementia: An updated meta-analysis

BACKGROUND

The behavioural and psychological symptoms of dementia (BPSD) have significant negative effects on the health of both patients with dementia and their caregivers. However, the reported effectiveness of non-pharmacological interventions targeting caregivers of patients with dementia for BPSD is inconsistent.

METHODS

We systematically searched the databases PubMed, PsycINFO, CINAHL, Embase, Cochrane Library and four Chinese databases from 2010 through April 2021. The Standardised mean difference (SMD) was calculated using random-effects models. Risk of bias in individual studies was assessed using Cochrane Collaboration's tool, and the certainty of evidence was assessed using the five GRADE criteria.

RESULTS

Thirty-one randomised controlled trials (RCTs) involving 3501 dyads were included. The meta-analysis indicated that non-pharmacological interventions showed small but significant effects on both BPSD in patients with dementia (SMD = -0.14; 95% CI, -0.22 to -0.06; P = 0.001) and caregiver reactions to BPSD (SMD = -0.16; 95% CI, -0.25 to -0.07; P = 0.001). The effect sizes of BPSD in patients at follow-up (SMD = -0.24; 95% CI, -0.38 to -0.09; P = 0.002) were larger than those at post-test. Tailored interventions were associated with more substantial reductions in BPSD in patients (SMD = -0.24; 95% CI, -0.37 to -0.11; P < 0.001) than standardised interventions (SMD = -0.07; 95% CI, -0.18 to 0.04; P = 0.218).

CONCLUSIONS

Non-pharmacological interventions targeting caregivers have the potential to reduce BPSD in patients with dementia and improve caregiver negative reactions to BPSD. Moreover, tailored interventions seemed to be more effective in reducing BPSD, and more significant improvements in BPSD may be observed in long-term follow-up.

Palliative care interventions in intensive care unit patients

PURPOSE

The integration of palliative care into intensive care units (ICUs) is advocated to mitigate physical and psychological burdens for patients and their families, and to improve end-of-life care. The most efficacious palliative care interventions, the optimal model of their delivery and the most appropriate outcome measures in ICU are not clear.

METHODS

We conducted a systematic review of randomised clinical trials and observational studies to evaluate the number and types of palliative care interventions implemented within the ICU setting, to assess their impact on ICU practice and to evaluate differences in palliative care approaches across different countries.

RESULTS

Fifty-eight full articles were identified, including 9 randomised trials and 49 cohort studies; all but 4 were conducted within North America. Interventions were categorised into five themes: communication (14, 24.6%), ethics consultations (5, 8.8%), educational (18, 31.6%), involvement of a palliative care team (28, 49.1%) and advance care planning or goals-of-care discussions (7, 12.3%). Thirty studies (51.7%) proposed an integrative model, whilst 28 (48.3%) reported a consultative one. The most frequently reported outcomes were ICU or hospital length of stay (33/55, 60%), limitation of life-sustaining treatment decisions (22/55, 40%) and mortality (15/55, 27.2%). Quantitative assessment of pooled data was not performed due to heterogeneity in interventions and outcomes between studies.

CONCLUSION

Beneficial effects on the most common outcomes were associated with strategies to enhance palliative care involvement, either with an integrative or a consultative approach. Few studies reported functional outcomes for ICU patients. Almost all studies were from North America, limiting the generalisability to other healthcare systems.

The stepwise development of an interactive web-based sex education programme for subfertile couples: the Pleasure & Pregnancy programme

STUDY QUESTION

Can we develop a web-based sex education programme (programme running in a web browser) that addresses the needs of subfertile couples who are advised expectant management for at least 6 months?

SUMMARY ANSWER

The 'Pleasure & Pregnancy' programme addresses couples' needs, is likely to improve couples' sexual functioning, and is subsequently hypothesised to improve the chance of natural pregnancy.

WHAT IS KNOWN ALREADY

According to professional guidelines (e.g. the Netherlands and UK) couples with unexplained subfertility and a good chance of natural pregnancy, should be advised at least 6 months of expectant management. Adherence to expectant management is challenging as couples and gynaecologist prefer a more active approach. Targeting sexuality may be useful as subfertility is a risk factor for decreased sexual functioning.

STUDY DESIGN, SIZE, DURATION

A novel programme was developed according to the three steps of the Medical Research Councils' (MRC) framework. First, relevant literature was explored. Second, an interdisciplinary expert panel developed a theory (based on a systematic literature review and patient interviews) on how the chance of natural conception can be improved. Third, the expected process and outcomes were modelled.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Two licenced clinical sexologists, two gynaecologists, a clinical embryologist and two midwife-researchers, all from Belgium and the Netherlands, proposed components for the sex education programme. PubMed was searched systematically for randomised controlled trials (RCTs) evaluating the proposed components in different patient populations. The needs of 12 heterosexual Dutch or Belgian couples who were advised expectant management were explored with in-depth interviews. The content and delivery characteristics of the novel programme were described in detail with the aid of 'Intervention Taxonomy'. To model the outcomes, a protocol for an RCT was designed, registered and submitted for publication.

MAIN RESULTS AND THE ROLE OF CHANCE

To help maintain or improve sexual functioning, mainly pleasure, and hence increase pregnancy rates, the web-based Pleasure & Pregnancy programme contains a combination of psychosexual education and couple communication, mindfulness and sensate focus exercises. Information on the biology of conception and interaction with fertility clinic staff and peers were added based on couples' needs to increase potential acceptability.

LIMITATIONS AND REASON FOR CAUTION

This paper outlines the development phase of a sex education programme according to the MRC-framework. Whether the Pleasure & Pregnancy programme actually is acceptable, improves sexual functioning, increases pregnancy rates and is cost-effective remains to be determined.

WIDER IMPLICATIONS OF THE FINDINGS

No previous interactive web-based sex education programme has aimed to increase the natural pregnancy rate of subfertile couples by targeting their sexual pleasure. The Pleasure & Pregnancy programme addresses couples' needs and its effect on sexual functioning and pregnancy rate is plausible but remains to be demonstrated by an RCT which is currently ongoing.

Effects of a health worker-led 3-month yoga intervention on blood pressure of hypertensive patients: a randomised controlled multicentre trial in the primary care setting

Background

Hypertension control remains a major challenge globally. A recent systematic review suggested that yoga has beneficial effects on reducing blood pressure. However, the role of yoga in hypertension management in primary health care has received little attention, and no studies have evaluated the impact of a yoga program fully delivered by health care staff on hypertension. This study, therefore, assessed the effects of a health worker-led yoga intervention on blood pressure reduction among hypertensives patients in the primary care setting.

Methods

This was a multicentric, two-arm, randomised trial conducted among hypertensive patients in seven Ayurveda Health Centres in Nepal between March 2017 and June 2018. One hundred and twenty-one participants who were on or without medications were randomised to intervention (n = 61) and wait-list control (n = 60) groups using stratified block randomisation. Participants in the intervention arm received an intervention consisting of an initial five-day structured yoga training at the centres and then a further home-based practice of yoga for five days a week for the following 90 days. Both intervention and control groups also participated in a 2-h health education session. The primary outcome of this trial was systolic blood pressure at 90-day follow-up. Data were analysed on an intention-to-treat basis using linear mixed-effects regression models.

Results

We included all 121 study participants (intervention/control = 61/60) in the primary analysis (52.1% males; mean ± SD age = 47.8 ± 10.8 years). The difference in systolic blood pressure between the intervention group and the control group was − 7.66 mmHg (95% CI: − 10.4, − 4.93). For diastolic blood pressure, the difference was − 3.86 mmHg (95% CI: − 6.65, − 1.06). No adverse events were reported by the participants.

Conclusions

A yoga program for hypertensive patients consisting of a five-day training in health centres and 90 days of practice at home is effective for reducing blood pressure. Significant benefits for hypertensive patients could be expected if such programmes would become a part of the standard treatment practice.

Trial registration

This trial was prospectively registered with the Clinical Trial Registry of India [CTRI/2017/02/007822] on 10/02/2017.

The International Classification of Health Interventions: an 'epistemic hub' for use in public health

The current lack of a common basis for collecting data on population-level prevention and health promotion interventions causes public health to be relatively invisible within broader health systems, making it vulnerable to funding cuts when there is pressure to reduce spending. Further, the inconsistent use of terms for describing interventions hinders knowledge translation and building an evidence base for public health practice and policy. The International Classification of Health Interventions (ICHI), being developed by the World Health Organization, is a standard statistical classification for interventions across the full scope of health systems. ICHI has potential to meet the need for a common language and structure for describing and capturing information about prevention and health promotion interventions. We report on a developmental appraisal conducted to examine the strengths and limitations of ICHI for coding interventions delivered for public health purposes. Our findings highlight classification challenges in relation to: consistently identifying separate components within multi-component interventions; operationalizing the ICHI concept of intervention target when there are intermediary targets as well as an ultimate target; coding an intervention component that involves more than one ICHI target or action; and standardising what is being counted. We propose that, alongside its purpose as a statistical classification, ICHI can play a valuable role as an 'epistemic hub', to be used flexibly by public health actors to meet a range of information needs, and as a basis for improved communication and exchange.

Psychosocial interventions to support the mental health of informal caregivers of persons living with dementia - a systematic literature review

Background

Informal caregivers of persons living with dementia have an increased risk of adverse mental health effects. It is therefore important to systematically summarize published literature in order to find out which mental health interventions generate effective support for informal caregivers of persons living with dementia. The objective of this study is to conduct a systematic review of intervention content, effectiveness and subgroup differentiation of mental health interventions for informal caregivers of persons with dementia living at home.

Method

We searched four electronic databases (PubMed, PsychINFO, Scopus and CINAHL) and included only methodically high-quality randomized controlled trials (RCTs), published in English or German language between 2009 and 2018. The intervention programmes focused on mental health of family caregivers. A narrative synthesis of the included studies is given.

Results

Forty-eight publications relating to 46 intervention programmes met the inclusion criteria. Burden, depression and quality of life (QoL) are the predominant parameters that were investigated. Twenty-five of forty-six interventions (54.3%) show positive effects on at least one of the outcomes examined. Most often, positive effects are reported for the outcome subjective burden (46.2%). Only six studies explicitly target on a certain subgroup of informal dementia caregivers (13%), whereas all other interventions (87%) target the group as a whole without differentiation.

Conclusion

The most beneficial results were found for cognitive behavioural approaches, especially concerning the reduction of depressive symptoms. Besides this, leisure and physical activity interventions show some good results in reducing subjective caregiver burden. In order to improve effectiveness, research and practice may focus on developing more targeted interventions for special dementia informal caregiver subgroups.

Small Improvements in an Urban Food Environment Resulted in No Changes in Diet Among Residents

Living in a low-income neighborhood with low access to healthy food retailers is associated with increased risk for chronic disease. The U.S. Healthy Food Financing Initiative (HFFI) provides resources to support the development of infrastructure to improve neighborhood food environments. This natural experiment examined a HFFI funded food hub that was designed to be implemented by a community development corporation in an urban neighborhood in Cleveland, Ohio. It was intended to increase access to affordable, local, and healthy foods; establish programs to increase social connections and support for healthy eating; and create job opportunities for residents. We used a quasi-experimental, longitudinal design to externally evaluate food hub implementation and its impact on changes to the built and social environment and dietary patterns among residents living in the intervention neighborhood (n = 179) versus those in a comparison (n = 150) neighborhood. Overall, many of the food hub components were not implemented fully, and dose and reach of the executed food hub components was low. There were statistically significant improvements in observed availability of healthy foods in the intervention neighborhood versus the comparison neighborhood. There were no changes over time in diet quality scores, total caloric intake, or fruit and vegetable intake in the intervention neighborhood. In conclusion, low dose implementation of a food hub led to small improvements in availability of healthy foods but not in dietary patterns. Findings highlight challenges to implementing a food hub in neighborhoods with low access to healthy food retailers.

Evaluation showed that stakeholders valued the support provided by the Implementing Pediatric Advance Care Planning Toolkit

AIM

This study described the development, and pilot evaluation, of the Implementing Pediatric Advance Care Planning Toolkit (IMPACT).

METHODS

Key elements of paediatric advance care planning (ACP) were defined using a systematic review, a survey of 168 paediatricians and qualitative studies of 13 children with life-limiting conditions, 20 parents and 18 paediatricians. Participants were purposively recruited from six Dutch university hospitals during September 2016 and November 2018. Key elements were translated into intervention components guided by theory. The acceptability of the content was evaluated by a qualitative pilot study during February and September 2019. This focused on 27 children with life-limiting conditions from hospitals, a hospice and home care, together with 41 parents, 11 physicians and seven nurses who cared for them.

RESULTS

IMPACT provided a holistic, caring approach to ACP, gave children a voice and cared for their parents. It provided information on ACP for families and clinicians, manuals to structure ACP conversations and training for clinicians in communication skills and supportive attitudes. The 53 pilot study participants felt that IMPACT was appropriate for paediatric ACP.

CONCLUSION

IMPACT was an appropriate intervention that supported a holistic approach towards paediatric ACP, focused on the child's perspective and provided care for their parents.

Family Caregiving for Older Adults

Family members are the primary source of support for older adults with chronic illness and disability. Thousands of published empirical studies and dozens of reviews have documented the psychological and physical health effects of caregiving, identified caregivers at risk for adverse outcomes, and evaluated a wide range of intervention strategies to support caregivers. Caregiving as chronic stress exposure is the conceptual driver for much of this research. We review and synthesize the literature on the impact of caregiving and intervention strategies for supporting caregivers. The impact of caregiving is highly variable, driven largely by the intensity of care provided and the suffering of the care recipient. The intervention literature is littered with many failures and some successes. Successful interventions address both the pragmatics of care and the emotional toll of caregiving. We conclude with both research and policy recommendations that address a national agenda for caregiving.

Effects of functional communication interventions for people with primary progressive aphasia and their caregivers: a systematic review

Objectives: Primary progressive aphasia (PPA) is a language led dementia characterised by progressive speech and language difficulties. Impairment focused PPA interventions that seek to remediate, alleviate or improve symptoms, dominate the research literature. Yet speech and language therapists (SLTs) report prioritising functional communication interventions (FCIs), which target engagement in an activity and participation in life situations. This systematic review investigates the research literature on FCIs for PPA to identify the key components of these interventions and their effectiveness.Method: A systematic search of databases identified 19 studies published between 1998 and 2018. Data were extracted from the articles using the Intervention Taxonomy adaptation (ITAX).Results: Results show that the two most common components of FCIs are to build on communication strategies people currently use, and to practise these strategies with a communication partner. There are variations in the interventions, such as location and dosage. All 19 studies report improvements, of which eight report statistically significant results. Forty-two different measures are used across the 19 studies.Conclusion: This study highlights that building on existing strategies and practising these with a CP, are key components of FCIs for people with PPA, yet there remains a lack of clarity around optimal dosage. Further rigorous research using a core set of outcome measures is a priority in this area.

Quality and extent of implementation of a nurse-led care management intervention: care coordination for health promotion and activities in Parkinson's disease (CHAPS)

BACKGROUND

A recent nurse-led, telephone-administered 18-month intervention, Care Coordination for Health Promotion and Activities in Parkinson's Disease (CHAPS), was tested in a randomized controlled trial and improved care quality. Therefore, intervention details on nurse care manager activity (types and frequencies) and participant actions are needed to support potential dissemination. Activities include nurse care manager use of a holistic organizing framework, identification of Parkinson's disease (PD)-related problems/topics, communication with PD specialists and care coordination, participant coaching, and participant self-care actions including use of a notebook self-care tool.

METHODS

This article reports descriptive data on the CHAPS intervention. The study setting was five sites in the Veterans Affairs Healthcare System. Sociodemographic data were gathered from surveys of study participants (community-dwelling veterans with PD). Nurse care manager intervention activities were abstracted from electronic medical records and logbooks. Statistical analysis software was used to provide summary statistics; closed card sorting was used to group some data.

RESULTS

Intervention participants (n = 140) were primarily men, mean age 69.4 years (standard deviation 10.3) and community-dwelling. All received the CHAPS Initial Assessment, which had algorithms designed to identify 31 unique CHAPS standard problems/topics. These were frequently documented (n = 4938), and 98.6% were grouped by assigned domain from the Organizing Framework (Siebens Domain Management Model™). Nurse care managers performed 27 unique activity types to address identified problems, collaborating with participants and PD specialists. The two most frequent unique activities were counseling/emotional support (n = 387) and medication management (n = 349). Both were among 2749 total performed activities in the category Implementing Interventions (coaching). Participants reported unique self-care action types (n = 23) including use of a new notebook self-care tool.

CONCLUSIONS

CHAPS nurse care managers implemented multiple activities including participant coaching and care coordination per the CHAPS protocol. Participants reported various self-care actions including use of a personalized notebook. These findings indicate good quality and extent of implementation, contribute to ensuring reproducibility, and support CHAPS dissemination as a real-world approach to improve care quality.

Effects of Technology Use on Ageing in Place: The iZi Pilots

In the iZi study in The Hague, use and acceptance of commercially available technology by home-dwelling older citizens was studied, by comparing self-efficacy and perceived physical and mental Quality of Life (QoL)-related parameters on an intervention location of 279 households and a control location of 301 households. Technology adoption was clinically significantly associated with increased perceived physical QoL, as compared with control group, depending on the number of technology interventions that were used. A higher number of adopted technologies was associated with a stronger effect on perceived QoL. We tried to establish a way to measure clinical significance by using mixed methods, combining quantitative and qualitative evaluation and feeding results and feedback of participants directly back into our intervention. In general, this research is promising, since it shows that successful and effective adoption of technology by older people is feasible with commercially available products amongst home-dwelling older citizens. We think this way of working provides a better integration of scientific methods and clinical usability but demands a lot of communication and patience of researchers, citizens, and policymakers. A change in policy on how to target people for this kind of intervention might be warranted.

Patient Engagement With an Automated Telephone Symptom Management Intervention: Predictors and Outcomes

BACKGROUND

Self-management of symptoms related to cancer and its treatment is important for maintaining treatment regimens and improving outcomes.

PURPOSE

To determine factors associated with engagement in a symptom self-management intervention among patients initiating oral anticancer treatment.

METHODS

This secondary analysis included 127 patients randomized to the medication adherence reminder and symptom management intervention in a recently completed trial. Patients were recruited from six Comprehensive Cancer Centers, interviewed at intake, and mailed a Symptom Management Toolkit (Toolkit) with self-care management strategies for 18 symptoms. During eight automated telephone weekly calls, patients were asked to use the Toolkit to manage elevated symptoms. Toolkit use and symptoms were tracked weekly, and generalized linear mixed-effects models were used to determine factors predictive of Toolkit use. General linear modeling was used to relate the Toolkit use during intervention to postintervention symptom severity.

RESULTS

Better cognitive function at intake into the trial and higher symptom burden were predictive of the patients' initial decision to try the Toolkit during Week 1. In subsequent weeks, Toolkit use in the previous week and worsening of symptoms were associated with greater odds of Toolkit use. The extent of Toolkit use modified the relationship between intake and 8 week symptom severity: among patients with higher levels of severity at intake, use of the Toolkit conferred greater benefit at 8 weeks.

CONCLUSIONS

Patients make realistic decisions regarding when to use a self-directed approach to self-management and are likely to use strategies when their symptoms are higher and to forego use once symptoms subside.

Which behaviour change techniques within interventions to prevent weight gain and/or initiate weight loss improve adiposity outcomes in young adults? A systematic review and meta-analysis of randomized controlled trials

Young adulthood is associated with the highest rate of weight gain compared with any other adult age group. This review evaluates the effectiveness of interventions with adiposity outcomes among young adults and identifies which behaviour change techniques (BCTs) are most effective. BCT utilization was assessed using Michie's 93-item BCT Taxonomy v1. Six electronic databases were searched for randomized controlled trials assessing change in adiposity in young adults (17-35 years) until December 2019; identifying 21,582 articles. Fifty-one studies were included. Meta-analyses for weight (n=19 studies), body mass index (BMI) (n=20 studies), and waist circumference (n=10 studies) demonstrated no significant between-group differences at ≤3 or >3 months. There were no differences between interventions focusing on weight loss or weight-gain prevention. Narrative synthesis showed significant between-group differences in weight change, favouring the intervention in 14/43 (33%) studies. In studies assessing BMI and waist circumference, this was 31% (11/36) and 25% (4/16). Two BCTs had a percentage effectiveness ratio >50% in weight loss interventions; social support (unspecified) and self-monitoring behaviour, and one in weight-gain prevention interventions; and goal-setting (outcome). Findings demonstrate initial potential for these types of BCTs and can help build cumulative evidence towards delivering effective, cost-efficient, and replicable interventions.

The ResidentialCare Transition Module: a single-blinded randomized controlled evaluation of a telehealth support intervention for family caregivers of persons with dementia living in residential long-term care

BACKGROUND

Families do not fully disengage from care responsibilities following relatives' admissions to residential long-term (RLTC) care settings such as nursing homes. Caregiver stress, depression, or other key outcomes remain stable or sometimes increase following a relative's RLTC entry. Some interventions have attempted to increase family involvement after institutionalization, but few rigorous studies have demonstrated whether these interventions are effective in helping families navigate the potential emotional and psychological upheaval presented by relatives' transitions to RLTC environments. The Residential Care Transition Module (RCTM) provides six formal sessions of consultation (one-to-one and family sessions) over a 4-month period to family caregivers who have admitted a relative to a RLTC setting.

METHODS

In this embedded mixed methods randomized controlled evaluation, family members who have admitted a cognitively impaired relative to a RLTC setting are randomly assigned to the RCTM (n = 120) or a usual care control condition (n = 120). Primary outcomes include reductions in family members' primary subjective stress and negative mental health outcomes; secondary role strains; and residential care stress. The mixed methods design will allow for an analysis of intervention action mechanisms by "embedding" qualitative components (up to 30 semi-structured interviews) at the conclusion of the 12-month evaluation.

DISCUSSION

This evaluation will fill an important clinical and research gap by evaluating a psychosocial intervention designed for families following RLTC admission that determines whether and how the RCTM can help families better navigate the emotional and psychological challenges of residential care transitions.

When a child dies: a systematic review of well-defined parent-focused bereavement interventions and their alignment with grief- and loss theories

BACKGROUND

The availability of interventions for bereaved parents have increased. However, most are practice based. To enhance the implementation of bereavement care for parents, an overview of interventions which are replicable and evidence-based are needed. The aim of this review is to provide an overview of well-defined bereavement interventions, focused on the parents, and delivered by regular health care professionals. Also, we explore the alignment between the interventions identified and the concepts contained in theories on grief in order to determine their theoretical evidence base.

METHOD

A systematic review was conducted using the methods PALETTE and PRISMA. The search was conducted in MEDLINE, Embase, and CINAHL. We included articles containing well-defined, replicable, paediatric bereavement interventions, focused on the parent, and performed by regular health care professionals. We excluded interventions on pathological grief, or interventions performed by healthcare professionals specialised in bereavement care. Quality appraisal was evaluated using the risk of bias, adapted risk of bias, or COREQ. In order to facilitate the evaluation of any theoretical foundation, a synthesis of ten theories about grief and loss was developed showing five key concepts: anticipatory grief, working models or plans, appraisal processes, coping, and continuing bonds.

RESULTS

Twenty-one articles were included, describing fifteen interventions. Five overarching components of intervention were identified covering the content of all interventions. These were: the acknowledgement of parenthood and the child's life; establishing keepsakes; follow-up contact; education and information, and; remembrance activities. The studies reported mainly on how to conduct, and experiences with, the interventions, but not on their effectiveness. Since most interventions lacked empirical evidence, they were evaluated against the key theoretical concepts which showed that all the components of intervention had a theoretical base.

CONCLUSIONS

In the absence of empirical evidence supporting the effectiveness of most interventions, their alignment with theoretical components shows support for most interventions on a conceptual level. Parents should be presented with a range of interventions, covered by a variety of theoretical components, and aimed at supporting different needs. Bereavement interventions should focus more on the continuous process of the transition parents experience in readjusting to a new reality.

Weight gain prevention content delivered to mothers: Lessons from an intervention embedded in a community organization

BACKGROUND

Transparent reporting of the intervention content study participants receive is particularly important for dissemination and implementation of evidence-based interventions to address obesity. This study explores intervention delivery and perceptions of content when an intervention is embedded within an organization's usual practice and associations with weight outcomes.

METHODS

This is a secondary analysis from the Healthy Eating and Active Living Taught at Home (HEALTH) randomized trial. HEALTH is a weight gain prevention intervention embedded within a national home visiting programme (Parents as Teachers, PAT). To be consistent with PAT practice, HEALTH has a suggested but also flexible home visit structure. Therefore, the number and frequency of home visits are determined by the family's needs and preferences based on the parent educator's professional judgement. The proportion of participants who received each curriculum core lesson was explored among the 105 families randomized to the HEALTH intervention group, as were mean parent educator perception ratings of the visits (5-point Likert-type scale). A chi-square test was used to examine the association between utilization (ie, low: 1-6, middle: 7-12, or high: 13-18 visits) category and weight maintenance.

RESULTS

Mothers received on average 13.3 (standard deviation 6.2) core visits. Mean parent educator perception of the mothers' response (out of 5) ranged from 3.99 to 4.27; educators' perception of their own experience with the lesson ranged from 4.13 to 4.34. Among mothers who maintained their weight, 13% were low, 22% were middle, and 65% were high utilizers, while among mothers who gained weight, 3%, 31%, and 67% were low, middle, and high utilizers, respectively; this difference was not statistically significant.

CONCLUSIONS

This study identified wide variation in the visits families received from the curriculum but minimal variation in visit perceptions. Future studies could explore whether there are optimal patterns for visit content, associated with successful outcomes.

Why is reporting quality improvement so hard? A qualitative study in perioperative care

OBJECTIVES

Quality improvement (QI) may help to avert or mitigate the risks of suboptimal care, but it is often poorly reported in the healthcare literature. We aimed to identify the influences on reporting QI in the area of perioperative care, with a view to informing improvements in reporting QI across healthcare.

DESIGN

Qualitative interview study.

SETTING

Healthcare and academic organisations in Australia, Europe and North America.

PARTICIPANTS

Stakeholders involved in or influencing the publication, writing or consumption of reports of QI studies in perioperative care.

RESULTS

Forty-two participants from six countries took part in the study. Participants included 15 authors (those who write QI reports), 12 consumers of QI reports (practitioners who apply QI research in practice), 11 journal editors and 4 authors of reporting guidelines. Participants identified three principal challenges in achieving high-quality QI reporting. First, the broad scope of QI reporting-ranging from small local projects to multisite research across different disciplines-causes uncertainty about where QI work should be published. Second, context is fundamental to the success of a QI intervention but is difficult to report in ways that support replication and development. Third, reporting is adversely affected by both proximal influences (such as lack of time to write up QI) and more distal, structural influences (such as norms about the format and content of biomedical research reporting), leading to incomplete reporting of QI findings.

CONCLUSIONS

Divergent terminology and understandings of QI, along with existing reporting norms and the challenges of capturing context adequately yet succinctly, make for challenges in reporting QI. We offer suggestions for improvement.

Deconstructing Weight Management Interventions for Young Adults: Looking Inside the Black Box of the EARLY Consortium Trials

OBJECTIVE

The goal of the present study was to deconstruct the 17 treatment arms used in the Early Adult Reduction of weight through LifestYle (EARLY) weight management trials.

METHODS

Intervention materials were coded to reflect behavioral domains and behavior change techniques (BCTs) within those domains planned for each treatment arm. The analytical hierarchy process was employed to determine an emphasis profile of domains in each intervention.

RESULTS

The intervention arms used BCTs from all of the 16 domains, with an average of 29.3 BCTs per intervention arm. All 12 of the interventions included BCTs from the six domains of Goals and Planning, Feedback and Monitoring, Social Support, Shaping Knowledge, Natural Consequences, and Comparison of Outcomes; 11 of the 12 interventions shared 15 BCTs in common across those six domains.

CONCLUSIONS

Weight management interventions are complex. The shared set of BCTs used in the EARLY trials may represent a core intervention that could be studied to determine the required emphases of BCTs and whether additional BCTs add to or detract from efficacy. Deconstructing interventions will aid in reproducibility and understanding of active ingredients.

Control Conditions That Are Neither Usual Care Nor No Treatment in Randomized Trials of Psychoeducational Palliative Care Interventions: A Systematic Review

BACKGROUND:

Determining intervention efficacy depends as much on the control group as on the intervention, but little attention has been given to the control condition in psychoeducational trials in palliative care.

OBJECTIVES:

To examine (1) research practice regarding control conditions that are neither usual care nor no-treatment controls in randomized trials of psychoeducational palliative care interventions and (2) the rationale and completeness of the descriptions of control conditions in trial reports.

METHODS:

PubMed, EMBASE, PsycINFO, and Web of Science were searched. After screening 1603 articles, 70 full-text articles were assessed for eligibility. The final sample included 9 trial reports. We used the Delphi list for quality assessment and the modified intervention taxonomy checklist to assess active intervention and control conditions.

RESULTS:

Four trials used an attention control designed to be equivalent to the structure of the active intervention. In another 4, the control condition included some aspects of attention control such that the mode of contact was similar to that in the active intervention, but either the amount or the intensity of attention was not similar. Only 3 trial reports explicitly stated the rationale for the choice of control condition. Although most reports contained delivery mode, materials, duration, frequency, and sequence, none described the qualifications or training required to deliver the control condition. Only 1 report mentioned the fidelity monitoring method, and none included fidelity data.

CONCLUSION:

Our review of psychoeducational trials in palliative care calls for researchers' attention to appropriate selection, design, conduct and report of control conditions.

Capturing the trend of mHealth research using text mining

BACKGROUND

With the increasing development and use of mobile technologies, an increasing amount of research on mobile health is being conducted. The purpose of the study was to capture the trends in mHealth research by mining terms related to medical conditions, interventions, study populations, and the relationships between these terms.

METHODS

This study analyzed 5,600 journal articles published in Web of Science from 2008 to 2018. Using text mining techniques, a total of 39,292 terms extracted from the titles and abstracts of the journal articles were independently reviewed to identify meaningful terms related to medical conditions, interventions, and study populations.

RESULTS

A total of 48 different types of medical conditions were identified in the dataset. Mood disorders appeared to be the most frequently identified medical condition in mHealth research. Thirty interventions were identified. Cell phone-, SMS-, and Internet-based interventions appeared to be the most prominent types, and "female" appeared to be the most frequently identified term related to the studied population. Females appeared to have been studied in the widest range of medical conditions, including pregnancy issues, overnutrition, neoplasms, and AIDS. Older adults were the least studied population in mHealth.

CONCLUSIONS

Knowledge gaps that have not been explored in previous studies in mHealth research were identified, which should be addressed by researchers.

The Tele.TAnDem Intervention: Telephone-based CBT for Family Caregivers of People With Dementia

Background and Objectives

This study evaluated the effectiveness of a telephone-based cognitive-behavioral therapy for family caregivers of people with dementia in existing health care provision structures.

Research Design and Methods

Two hundred seventy-three family caregivers of people with dementia were randomly assigned to receive the intervention or usual care. Usual care included unrestricted access to community resources. Intervention group participants received twelve 50-min sessions of individual cognitive-behavioral therapy by trained psychotherapists within 6 months. Symptoms of depression, emotional well-being, physical health symptoms, burden of care, coping with the care situation and challenging behavior were assessed after the intervention ended and at a 6-month follow-up. Intention-to-treat analyses using latent change models were applied.

Results

Intention-to-treat analyses showed improved emotional well-being (γ = 9.59, p = .001), fewer symptoms of depression (γ = -0.23, p = .043), fewer physical health symptoms (γ = -0.25, p = .019), improved coping with the care situation (γ = 0.25, p = .005) and the behavior of the care recipient (γ = 0.23, p = .034) compared with usual care. Effects for coping (γ = 0.28, p = .006 and γ = 0.39, p < .001, respectively) and emotional well-being (γ = 7.61, p = .007) were also found at follow-up.

Discussion and Implications

The CBT-based telephone intervention increased mental and physical health as well as coping abilities of family caregivers of people with dementia. The intervention can be delivered by qualified CBT therapists after an 8-h training session in existing health care provision structures.

Stroke communication partner training: a national survey of 122 clinicians on current practice patterns and perceived implementation barriers and facilitators

BACKGROUND

Communication partners (CPs) find it challenging to communicate with people with communication disorders post-stroke. Stroke communication partner training (CPT) can enhance CPs' ability to support the communication and participation of people post-stroke. While evidence for the efficacy of aphasia-based CPT is strong, implementation in healthcare settings is unclear.

AIMS

To investigate Australian speech pathologists' current stroke CPT practices, factors influencing the implementation of CPT and how reported practice compares with the research evidence.

METHODS & PROCEDURES

Speech pathologists in Australia who had worked with people post-stroke were invited to complete a 99-item online survey. The survey was informed by a comprehensive review of the literature review, the Template for Intervention Description and Replication (TIDieR) intervention taxonomy, and the theoretical domains framework. data were analyzed using descriptive statistics and content analysis.

OUTCOMES & RESULTS

A total of 122 clinicians were surveyed. Most participants reported providing CPT to treat a range of post-stroke communication disorders. While 98.3% reported training familiar CPs, only 66.1% reported training unfamiliar CPs. Current stroke CPT practice is characterized by one to two < 1 h sessions of informal face-to-face education and skills training. Only 13.3% and 10.0% of participants used evidence-based published programmes with unfamiliar and familiar CPs respectively. The main barriers included the perceived lack of behavioural regulation, skills, reinforcement, beliefs about consequences, positive social influences and resources. The main facilitators included clinicians' intentions to provide CPT, perception of CPT as part of their role and perceived compatibility of CPT with clinical practice.

CONCLUSION & IMPLICATIONS

A significant evidence-practice gap exists. Research exploring the implementation of stroke CPT in healthcare settings, expanding evidence to support CPT for the range of post-stroke communication disorders, developing freely accessible step-by-step CPT programmes that consider restrictions in current practice and providing explicit instructions of CPT best practice are warranted. A supportive workplace culture and freely accessible formal training opportunities are also needed.

Common and distinct components of communication partner training programmes in stroke, traumatic brain injury and dementia

BACKGROUND

Communication partner training (CPT) programmes for health and care staff working with people with the neurologically based communication disorders associated with stroke, traumatic brain injury (TBI) and dementia are efficacious in improving communication. However, current programmes are lengthy and disorder specific, and therefore may not be suitable as staff training tools in environments with people with multiple communication disorders, and services with a variety of neurological populations.

AIMS

To identify common and distinct components of CPT programmes for stroke, TBI and dementia in order to determine whether there are common delivery methods and content that can be consolidated to improve implementation of CPT in health and care services.

METHODS & PROCEDURES

A qualitative enquiry was used. Four CPT programmes targeting three disorders were identified from systematic reviews and literature searches. Programme data were recorded onto data sheets from manuals, study articles and supplementary materials, and were categorized using the Intervention Taxonomy (ITAX). Content analysis and elements of constant comparative analysis were employed to analyse the CPT programmes.

OUTCOMES & RESULTS

Delivery characteristics were similar across all four programmes. All were delivered face to face in either group or individual contexts. However, duration varied from 1 to 35 h. Six of the 12 categories of information provided were common across all programmes, including 'strategy' 'background to disorder', 'information about communication', 'information about program', 'negative behaviours to avoid' and 'purpose of program'. Programmes differed in the types of skill-building techniques used, with the most common being videos (3/4 programmes), discussions (2/4 programmes) and trainer demonstrations (2/4 programmes). While strategies provided to trained partners targeted similar domains of communication, only 3/96 individual strategies were common to all programmes.

CONCLUSIONS & IMPLICATIONS

There are both common and distinct components in content and delivery methods across CPT programmes. Further research is needed to evaluate the distinct components of the programmes, to determine which individual strategies are efficacious, and which approach to skill-building techniques is most effective. The present study has contributed a comprehensive list of programme components, which can form a basis for describing and refining CPT programmes in future.

Specifying sickle cell disease interventions: a study protocol of the Sickle Cell Disease Implementation Consortium (SCDIC)

BACKGROUND

Sickle cell disease (SCD) is an inherited blood disorder that results in a lifetime of anemia, severe pain, and end-organ damage that can lead to premature mortality. While the SCD field has made major medical advances, much needs to be done to improve the quality of care for people with SCD. This study capitalizes on the Sickle Cell Disease Implementation Consortium (SCDIC), a consortium of eight academic sites aiming to test implementation strategies that could lead to more accelerated application of the NHLBI guidelines for treating SCD. This report documents the process to support the consortium by specifying the interventions being developed.

METHODS

This study consists of three steps. The Principal Investigator of each site and two site representatives who are knowledgeable of the intervention (e.g., study coordinator or the person delivering the intervention) will answer an online survey aiming to capture components of the interventions. This survey will be completed by the site representatives three times during the study: during the development of the interventions, after one year of the interventions being implemented, and at the end of this study (after 2 years). A site visit and semi-structured interview (Step 2) in the first year of the process will capture the context of the sites. Step 3 comprises of the development of a framework with the details of the multi-component SCDIC interventions at the sites.

DISCUSSION

The outcome of this study, a framework of the SCDIC, will enable accurate replication and extension of published research, facilitating the translation of SCD studies to diverse populations and settings and allowing for theory testing of the effects of the intervention components across studies in different contexts and for different populations.

Design and development of a complex narrative intervention delivered by text messages to reduce binge drinking among socially disadvantaged men

Background

Socially disadvantaged men are at high risk of suffering from alcohol-related harm. Disadvantaged groups are less likely to engage with health promotion. There is a need for interventions that reach large numbers at low cost and which promote high levels of engagement with the behaviour change process. The aim of this study was to design a theoretically and empirically based text message intervention to reduce binge drinking by socially disadvantaged men.

Results

Following MRC guidance, the intervention was developed in four stages. Stage 1 developed a detailed behaviour change strategy based on existing literature and theory from several areas. These included the psychological theory that would underpin the intervention, alcohol brief interventions, text message interventions, effective behaviour change techniques, narratives in behaviour change interventions and communication theory. In addition, formative research was carried out. A logic model was developed to depict the pathways between intervention inputs, processes and outcomes for behaviour change. Stage 2 created a narrative which illustrated and modelled key steps in the strategy. Stage 3 rendered the intervention into a series of text messages and ensured that appropriate behavioural change techniques were incorporated. Stage 4 revised the messages to ensure comprehensive coverage of the behaviour change strategy and coherence of the narrative. It also piloted the intervention and made final revisions to it.

Conclusions

The structured, systematic approach to design created a narrative intervention which had a strong theoretical and empirical basis. The use of a narrative helped make the intervention realistic and allowed key behaviour change techniques to be modelled by characters. The narrative was intended to promote engagement with the intervention. The intervention was rendered into a series of short text messages, and subsequent piloting showed they were acceptable in the target group. Delivery of an intervention by text message offers a low-cost, low-demand method that can reach large numbers of people. This approach provides a framework for the design of behaviour change interventions which could be used for interventions to tackle other health behaviours.

Mental health supported accommodation services: a systematic review of mental health and psychosocial outcomes

BACKGROUND

Post-deinstitutionalisation, mental health supported accommodation services have been implemented widely. The available research evidence is heterogeneous in nature and resistant to synthesis attempts, leaving researchers and policy makers with no clear summary what works and for whom. In this context, we undertook a comprehensive systematic review of quantitative studies in order to synthesise the current evidence on mental health and psychosocial outcomes for individuals residing in mental health supported accommodation services.

METHODS

Using a combination of electronic database searches, hand searches, forward-backward snowballing and article recommendations from an expert panel, 115 papers were identified for review. Data extraction and quality assessments were conducted, and 33 articles were excluded due to low quality, leaving 82 papers in the final review. Variation in terminology and service characteristics made the comparison of service models unfeasible. As such, findings were presented according to the following sub-groups: 'Homeless', 'Deinstitutionalisation' and 'General Severe Mental Illness (SMI)'.

RESULTS

Results were mixed, reflecting the heterogeneity of the supported accommodation literature, in terms of research quality, experimental design, population, service types and outcomes assessed. There is some evidence that supported accommodation is effective across a range of psychosocial outcomes. The most robust evidence supports the effectiveness of the permanent supported accommodation model for homeless SMI in generating improvements in housing retention and stability, and appropriate use of clinical services over time, and for other forms of supported accommodation for deinstitutionalised populations in reducing hospitalisation rates and improving appropriate service use. The evidence base for general SMI populations is less developed, and requires further research.

CONCLUSIONS

A lack of high-quality experimental studies, definitional inconsistency and poor reporting continue to stymie our ability to identify effective supported accommodation models and practices. The authors recommend improved reporting standards and the prioritisation of experimental studies that compare outcomes across different service models.

Interventionist training and intervention fidelity monitoring and maintenance for CONNECT, a nurse-led primary palliative care in oncology trial

Context

Intervention fidelity is a critical component of behavioral research that has received inadequate attention in palliative care studies. With increasing focus on the need for palliative care models that can be widely disseminated and delivered by non-specialists, rigorous yet pragmatic strategies for training interventionists and maintaining intervention fidelity are needed.

Objectives

(1) Describe components of a plan for interventionist training and monitoring and maintaining intervention fidelity as part of a primary palliative care trial (CONNECT) and (2) present data about perceived training effectiveness and delivery of key intervention content.

Methods

Post-training evaluations, visit checklists, and visit audio-recordings.

Results

Data were collected from June, 2016 through April, 2017. We include procedures for (1) identification, training and certification of oncology nurses as CONNECT interventionists; (2) monitoring intervention delivery; and (3) maintaining intervention quality. All nurses (N = 14) felt prepared to deliver key competencies after a 3-day in-person training. As assessed via visit checklists, interventionists delivered an average of 94% (SD 13%) of key content for first intervention visits and 85% (SD 14%) for subsequent visits. As assessed via audio-recordings, interventionists delivered an average of 85% (SD 8%) of key content for initial visits and 85% (SD 12%) for subsequent visits.

Conclusion

We present a 3-part strategy for training interventionists and monitoring and maintaining intervention delivery in a primary palliative care trial. Training was effective in having nurses feel prepared to deliver primary palliative care skills. As assessed via nursing checklists and visit audio-recordings, intervention fidelity was high.

Classification schemes for knowledge translation interventions: a practical resource for researchers

BACKGROUND

As implementation science advances, the number of interventions to promote the translation of evidence into healthcare, health systems, or health policy is growing. Accordingly, classification schemes for these knowledge translation (KT) interventions have emerged. A recent scoping review identified 51 classification schemes of KT interventions to integrate evidence into healthcare practice; however, the review did not evaluate the quality of the classification schemes or provide detailed information to assist researchers in selecting a scheme for their context and purpose. This study aimed to further examine and assess the quality of these classification schemes of KT interventions, and provide information to aid researchers when selecting a classification scheme.

METHODS

We abstracted the following information from each of the original 51 classification scheme articles: authors' objectives; purpose of the scheme and field of application; socioecologic level (individual, organizational, community, system); adaptability (broad versus specific); target group (patients, providers, policy-makers), intent (policy, education, practice), and purpose (dissemination versus implementation). Two reviewers independently evaluated the methodological quality of the development of each classification scheme using an adapted version of the AGREE II tool. Based on these assessments, two independent reviewers reached consensus about whether to recommend each scheme for researcher use, or not.

RESULTS

Of the 51 original classification schemes, we excluded seven that were not specific classification schemes, not accessible or duplicates. Of the remaining 44 classification schemes, nine were not recommended. Of the 35 recommended classification schemes, ten focused on behaviour change and six focused on population health. Many schemes (n = 29) addressed practice considerations. Fewer schemes addressed educational or policy objectives. Twenty-five classification schemes had broad applicability, six were specific, and four had elements of both. Twenty-three schemes targeted health providers, nine targeted both patients and providers and one targeted policy-makers. Most classification schemes were intended for implementation rather than dissemination.

CONCLUSIONS

Thirty-five classification schemes of KT interventions were developed and reported with sufficient rigour to be recommended for use by researchers interested in KT in healthcare. Our additional categorization and quality analysis will aid in selecting suitable classification schemes for research initiatives in the field of implementation science.

Development and testing of a goals of care intervention in advanced heart failure

AIM

The purpose of this paper is to describe the conceptual framework for a goals of care (GoC) intervention, elements, and findings of intervention feasibility, acceptability, and benefits from both patients with heart failure (HF) and their providers.

BACKGROUND

Receiving care at a mechanical circulatory support center for advanced HF offers new opportunities for treatment, making the implementation of a GoC intervention timely and crucial in helping patients determine next steps in HF treatment.

METHODS

The GoC intervention was designed using a self-management framework, incorporating the concepts of self-efficacy, patient activation, and patient motivation. At the conclusion of the study, open-ended exit interviews were conducted with patients and providers. Content analysis was used to derive the feasibility, acceptability, and benefits of the intervention.

RESULTS

Forty-one patients with HF, with average age 58.2±11.3years, LVEF=30.3±9.7%, and New York Heart Association Functional Class (NYHA FC)=2.4±0.8, and nine HF providers participated in the study. Patient benefits from the intervention included enhanced communication with their provider and family members, increased confidence to have a conversation with the provider, and refreshed HF knowledge. Provider benefits from the intervention were facilitating a conversation with the patient and learning new information about the patient's goals and values.

CONCLUSION

The GoC intervention provides an avenue to align patient goals and values with treatment choices in the context of advanced heart failure, so that patient quality of life is enhanced and costs of care can be reduced.

Utilizing evidence-based assessment instruments to detect well-being and distress in English- and Spanish-speaking caregivers of individuals affected by dementia

Objective

The purpose of this study was to examine the most effective and available English and Spanish language caregiver assessments for providers and caregivers.

Methods

Assessments were included if they screened for caregiving-related concerns, including stress, depression, and caregiving burden and could be administered directly to caregivers in person or online.

Results

Eighteen assessments are designed to assess caregiver burden, distress, depression, and grief. Six did not have psychometric data to support efficacy but are widely used in clinical and research settings. Six were validated in Spanish, and one other is available in Spanish but not validated.

Conclusion

As many as 80% of care recipients are cared for in the home by family members who act as informal caregivers. Caregivers of persons with dementia may experience depression symptoms, high caregiver burden, and feelings of being constrained. Due to the lack of psychometric evidence available, the validity of some assessments is questionable.

Overview of the obesity intervention taxonomy and pooled analysis working group

The National Heart, Lung, and Blood Institute and the National Institutes of Health Office of Disease Prevention convened a meeting on August 29-30, 2013 entitled "Obesity Intervention Taxonomy and Pooled Analysis." The overarching goals of the meeting were to understand how to decompose interventions targeting behavior change, and in particular, those that focus on obesity and to combine data from groups of related intervention studies to supplement what can be learned from the individual studies. This paper summarizes the workshop recommendations and provides an overview of the two other papers that originated from the workshop and that address decomposition of behavioral change interventions and pooling of data across diverse studies within a consortium.

Statistical methodologies to pool across multiple intervention studies

Combining and analyzing data from heterogeneous randomized controlled trials of complex multiple-component intervention studies, or discussing them in a systematic review, is not straightforward. The present article describes certain issues to be considered when combining data across studies, based on discussions in an NIH-sponsored workshop on pooling issues across studies in consortia (see Belle et al. in Psychol Aging, 18(3):396-405, 2003). Several statistical methodologies are described and their advantages and limitations are explored. Whether weighting the different studies data differently, or via employing random effects, one must recognize that different pooling methodologies may yield different results. Pooling can be used for comprehensive exploratory analyses of data from RCTs and should not be viewed as replacing the standard analysis plan for each study. Pooling may help to identify intervention components that may be more effective especially for subsets of participants with certain behavioral characteristics. Pooling, when supported by statistical tests, can allow exploratory investigation of potential hypotheses and for the design of future interventions.

A SYSTEMATIC APPROACH FOR ASSESSING, IN THE ABSENCE OF FULL EVIDENCE, WHETHER MULTICOMPONENT INTERVENTIONS CAN BE MORE COST-EFFECTIVE THAN SINGLE COMPONENT INTERVENTIONS

OBJECTIVES

Multicomponent interventions (MCIs), consisting of at least two interventions, are common in rehabilitation and other healthcare fields. When the effectiveness of the MCI versus that of its single interventions is comparable or unknown, evidence of their expected incremental cost-effectiveness can be helpful in deciding which intervention to recommend. As such evidence often is unavailable this study proposes an approach to estimate what is more cost-effective; the MCI or the single intervention(s).

METHODS

We reviewed the literature for potential methods. Of those identified, headroom analysis was selected as the most suitable basis for developing the approach, based on the criteria of being able to estimate the cost-effectiveness of the single interventions versus that of the MCI (a) within a limited time frame, (b) in the absence of full data, and (c) taking into account carry-over and interaction effects. We illustrated the approach with an MCI for cancer survivors.

RESULTS

The approach starts with analyzing the costs of the MCI. Given a specific willingness-to-pay-value, it is analyzed how much effectiveness the MCI would need to generate to be considered cost-effective, and if this is likely to be attained. Finally, the cost-effectiveness of the single interventions relative to the potential of the MCI for being cost-effective can be compared.

CONCLUSIONS

A systematic approach using headroom analysis was developed for estimating whether an MCI is likely to be more cost effective than one (or more) of its single interventions.

Developing implementation science to improve the translation of research to address low back pain: A critical review

The evidence base regarding treatment for back pain does not align with clinical practice. Currently there is relatively little evidence to guide health decision-makers on how to improve the use, uptake or adoption of evidence-based recommended practice for low back pain. Improving the design, conduct and reporting of strategies to improve the implementation of back pain care will help address this important evidence-practice gap. In this paper, we.

Early Interventions Following the Death of a Parent: Protocol of a Mixed Methods Systematic Review

BACKGROUND

Previous meta-analyses examined the effectiveness of interventions for bereaved children showing small to moderate effect sizes. However, no mixed methods systematic review was conducted on bereavement interventions following the loss of a parent focusing on the time since death in regard to the prevention of grief complications.

OBJECTIVE

The overall purpose of the review is to provide a rigorous synthesis of early intervention after parental death in childhood. Specifically, the aims are twofold: (1) to determine the rationales, contents, timeframes, and outcomes of early bereavement care interventions for children and/or their parents and (2) to assess the quality of current early intervention studies.

METHODS

Quantitative, qualitative, and mixed methods intervention studies that start intervention with parentally bereaved children (and/or their parents) up to 6 months postloss will be included in the review. The search strategy was based on the Population, Interventions, Comparator, Outcomes, and Study Designs (PICOS) approach, and it was devised together with a university librarian. The literature searches will be carried out in the Medical Literature Analysis and Retrieval System Online (MEDLINE), PsycINFO, Excerpta Medica Database (EMBASE), and Cumulative Index to Nursing and Allied Health Literature (CINAHL). The Mixed Methods Appraisal Tool will be used to appraise the quality of eligible studies. All data will be narratively synthetized following the Guidance on the Conduct of Narrative Synthesis in Systematic Reviews.

RESULTS

The systematic review is ongoing and the data search has started. The review is expected to be completed by the end of 2017. Findings will be submitted to leading journals for publication.

CONCLUSIONS

In accordance with the current diagnostic criteria for prolonged grief as well as the users' perspectives literature, this systematic review outlines a possible sensitive period for early intervention following the death of a parent. The hereby presented protocol ensures the groundwork and transparency for the process of conducting the systematic review.
