Lessons from the field: challenges in accruing hospice heart failure patients to intervention research

Advanced heart failure: parenteral diuretics for breathlessness and peripheral oedema - systematic review

BACKGROUND

Advanced heart failure patients suffer with breathlessness and peripheral oedema, which are frequently treated with parenteral diuretics despite limited evidence.

AIM

To analyse the effectiveness of parenteral diuretics on breathlessness and peripheral oedema in advanced heart failure patients.

METHODS

We searched Embase, MEDLINE(R), PsycINFO, CINAHL and CENTRAL from their respective inceptions to 2021, and performed handsearching, citation searching and grey literature search; limited to English publications. Selection criteria included parenteral (intravenous/subcutaneous) diuretic administration in advanced heart failure patients (New York Heart Association class III-IV). Two authors independently assessed articles for inclusion; one author extracted data. Data were synthesised through narrative synthesis or meta-analysed as appropriate.

RESULTS

4646 records were screened; 6 trials (384 participants) were included. All were randomised controlled trials (RCTs) comparing intravenous continuous furosemide infusion (CFI) versus intravenous bolus furosemide infusion (BFI). Improvement in breathlessness and peripheral oedema (two studies, n=161, OR 2.80, 95% CI 1.45 to 5.40; I2=0%), and increase in urine output (four studies, n=234, mean difference, MD 344.76, 95% CI 132.87 to 556.64; I2=44%), were statistically significant in favour of CFI. Significantly lower serum potassium was found in BFI compared with CFI (three studies, n=194, MD -0.20, 95% CI -0.38 to -0.01; I2=0%). There was no difference between CFI and BFI on reduction in weight, renal function or length of hospital stay.

CONCLUSIONS

CFI appears to improve congestion in advanced heart failure patients in the short term. Available data came from small trials. Larger, prospective RCTs are recommended to address the evidence gap.

The Effect of Digital Literacy on Participation in Social Media Clinical Trials in Cancer: Tailoring an Informed Consent Process

Introduction: This study asked: (1) How does digital literacy influence one's decision to consent to a social media intervention study? (2) What is a brief way to assess individual digital literacy before an individual's decision to participate in a trial? and (3) How can a consent process be tailored around an individual's digital literacy level? Methods: We used an assessment tool to investigate digital literacy of those who chose to consent to a clinical trial and those who did not consent to the clinical trial but agreed to participate in a digital literacy study. Results A total of 161 hospice caregivers completed the digital literacy assessment. Older individuals and those who rated themselves as more proficient in the use of technology and social media were more likely to consent to the social media clinical trial. Conclusions: We found that asking participants to rate their technology skills and social media skills allows researchers to tailor a consent process. For those who are comfortable with technology and social media the traditional process is appropriate. For individuals that rate themselves with weaker technology and social media skills it is important that the consent process includes assurance they will receive adequate support in the use of the technology and the media. The next step is to test the assessment and tailoring of consent processes for a social media clinical trial. Clinical Trial # NCT02929108.

Using the 'Social Marketing Mix Framework' to explore recruitment barriers and facilitators in palliative care randomised controlled trials? A narrative synthesis review

BACKGROUND

Effective recruitment to randomised controlled trials is critically important for a robust, trustworthy evidence base in palliative care. Many trials fail to achieve recruitment targets, but the reasons for this are poorly understood. Understanding barriers and facilitators is a critical step in designing optimal recruitment strategies.

AIM

To identify, explore and synthesise knowledge about recruitment barriers and facilitators in palliative care trials using the '6 Ps' of the 'Social Marketing Mix Framework'.

DESIGN

A systematic review with narrative synthesis.

DATA SOURCES

Medline, CINAHL, PsycINFO and Embase databases (from January 1990 to early October 2016) were searched. Papers included the following: interventional and qualitative studies addressing recruitment, palliative care randomised controlled trial papers or reports containing narrative observations about the barriers, facilitators or strategies to increase recruitment.

RESULTS

A total of 48 papers met the inclusion criteria. Uninterested participants (Product), burden of illness (Price) and 'identifying eligible participants' were barriers. Careful messaging and the use of scripts/role play (Promotion) were recommended. The need for intensive resources and gatekeeping by professionals were barriers while having research staff on-site and lead clinician support (Working with Partners) was advocated. Most evidence is based on researchers' own reports of experiences of recruiting to trials rather than independent evaluation.

CONCLUSION

The 'Social Marketing Mix Framework' can help guide researchers when planning and implementing their recruitment strategy but suggested strategies need to be tested within embedded clinical trials. The findings of this review are applicable to all palliative care research and not just randomised controlled trials.

Strategies to address the shortcomings of commonly used advanced chronic heart failure descriptors to improve recruitment in palliative care research: A parallel mixed-methods feasibility study

BACKGROUND

Recruitment challenges contribute to the paucity of palliative care research with advanced chronic heart failure patients.

AIM

To describe the challenges and outline strategies of recruiting advanced chronic heart failure patients.

DESIGN

A feasibility study using a pre-post uncontrolled design.

SETTING

Advanced chronic heart failure patients were recruited at two nurse-led chronic heart failure disease management clinics in Ireland Results: Of 372 patients screened, 81 were approached, 38 were recruited (46.9% conversion to consent) and 25 completed the intervention. To identify the desired population, a modified version of the European Society of Cardiology definition was used together with modified New York Heart Association inclusion criteria to address inter-study site New York Heart Association classification subjectivity. These modifications substantially increased median monthly numbers of eligible patients approached (from 8 to 20) and median monthly numbers recruited (from 4 to 9). Analysis using a mortality risk calculator demonstrated that recruited patients had a median 1-year mortality risk of 22.7 and confirmed that the modified eligibility criteria successfully identified the population of interest. A statistically significant difference in New York Heart Association classification was found in recruited patients between study sites, but no statistically significant difference was found in selected clinical parameters between these patients.

CONCLUSION

Clinically relevant modifications to the European Society of Cardiology definition and strategies to address New York Heart Association subjectivity may help to improve advanced chronic heart failure patient recruitment in clinical settings, thereby helping to address the paucity of palliative care research this population.

Patient participation in patients with heart failure receiving structured home care--a prospective longitudinal study

BACKGROUND

Patient participation is important for improving outcomes, respect for self-determination and legal aspects in care. However, how patients with heart failure view participation and which factors may be associated with participation is not known. The aim of this study was therefore to describe the influence of structured home care on patient participation over time in patients diagnosed with heart failure, and to explore factors associated with participation in care.

METHODS

The study had a prospective pre-post longitudinal design evaluating the influence of structured home care on participation in patients at four different home care units. Patient participation was measured using 3 scales and 1 single item. Self-care behavior, knowledge, symptoms of depression, socio- demographic and clinical characteristics were measured to explore factors associated with patient participation. Repeated measure ANOVA was used to describe change over time, and stepwise regression analyses were used to explore factors associated with patient participation.

RESULTS

One hundred patients receiving structured heart failure home care were included. Mean age was 82 years, 38 were women and 80 were in New York Heart Association functional class III. One aspect of participation, received information, showed a significant change over time and had increased at both six and twelve months. Better self-care behavior was associated with all four scales measuring different aspects of participation. Experiencing lower degree of symptoms of depression, having better knowledge, being of male sex, being of lower age, cohabiting and having home help services were associated with one or two of the four scales measuring different aspects of participation.

CONCLUSION

Patients experienced a fairly high level of satisfaction with participation in care at baseline, and there was a significant improvement over time for participation with regard to received information after being admitted to structured home care. Higher level of patient participation was consistently associated with better self-care behavior. This study shows that patient participation may need to be further focused upon, and that the association with self-care may be interesting to target in future interventions.
