The Preimplantation Psychosocial Evaluation and Prediction of Clinical Outcomes During Mechanical Circulatory Support: What Information Is Most Prognostic?

Association between psychosocial factors and left ventricular assist device implant outcomes: A systematic review

BACKGROUND

Psychosocial assessment is a core component of the multidisciplinary evaluation for left ventricular assist device (LVAD) implantation. The degree to which psychosocial conditions are considered a contraindication to LVAD implantation continues to be debated. This systematic review examines modifiable psychosocial factors as predictors of outcomes in patients undergoing LVAD implantation.

METHODS

We conducted a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline. The search resulted in 2509 articles. After deduplication, abstract and full-text review, 20 relevant articles were identified.

RESULTS

Included studies evaluated socioeconomic status (n = 6), caregiver characteristics (n = 6), non-adherence (n = 6), substance use (n = 13), and psychiatric disorder (n = 8). The most commonly measured outcomes were all-cause death, readmission rate, and adverse events. Studies varied widely in definition of each psychosocial factor and selected outcomes. No psychosocial factor was consistently associated with a specific outcome in all studies. Socioeconomic status was generally not associated with outcomes. Non-adherence, psychiatric disorder, and substance use were associated with higher risks of mortality, adverse events, and/or readmission. Findings on caregiver characteristics were mixed.

CONCLUSION

Of the psychosocial factors studied, non-adherence, psychiatric disorder, and substance use were the most consistently associated with an increased risk of mortality, readmission, and/or adverse events. Heterogeneity in research methodology and study quality across studies precludes firm conclusions regarding the impact of psychosocial factors on long-term patient outcomes. The results of this review reveal a need for adequately powered studies that use uniform definitions of psychosocial factors to clarify relationships between these factors and outcomes after LVAD implantation.

Palliative Care in Adult Congenital Heart Disease-Associated Advanced Heart Disease

The practice of palliative care (PC) strives to mitigate patient suffering through aligning patient priorities and values with care planning and via improved understanding of complex physical, psychosocial, and spiritual stressors and dynamics that contribute to patient-centered outcomes. Through representative 'case examples' and supportive data, the role and value of a PC consultant, within the framework of a comprehensive adult congenital heart disease (ACHD) team caring for ACHD with advanced heart disease, are reviewed.

Adverse events after left ventricular assist device implantation linked to psychosocial risk in women and men

BACKGROUND

Reasons for women's increased probability to experience adverse events (AEs) after left ventricular assist device (LVAD) implantation compared with men's remain uncertain. We explored the role of psychosocial risk in the experience of AEs in women and men.

METHODS

INTERMACS patients receiving a primary continuous-flow LVAD between July 2006 and December 2017, median follow-up 13.6 months, were included (n = 20,123, 21.3% women). Time-to-event was calculated with cumulative incidence functions for 10 types of AEs separately (e.g., infection, device malfunction), each time accounting for the competing outcomes death, heart transplant, and device explant due to recovery. Event-specific Cox proportional hazard models were run with a binary psychosocial risk variable (including substance abuse, psychiatric diagnosis, limited social support, limited cognition, repeated noncompliance), controlled for covariates.

RESULTS

Psychosocial risk was more prevalent in men than in women (21.4% vs 17.5%, p < 0.001). Seven out of 10 AEs were more likely in women than in men (e.g., infection 44.5% vs 39.2%, p < 0.001). The association of psychosocial risk with each AE was either stronger in women than in men (e.g., device malfunction HRadj 1.29, 95% confidence interval (CI) (1.06-1.56) vs HRadj 1.10, 95% CI (0.97-1.25); rehospitalization HRadj 1.15, 95% CI (1.02-1.29) vs HRadj 1.03, 95% CI (0.97-1.10) or similar between sexes.

CONCLUSIONS

Independent of clinical parameters, the presence of psychosocial risk is associated with increases in AEs. This suggests that early modification of psychosocial risk factors may have the potential to lower the risk for AEs in this patient population.

Variation in Left Ventricular Assist Device Postdischarge Caregiver Requirements: Results From a Mixed-Methods Study With Equity Implications

BACKGROUND

Left ventricular assist device (LVAD) evaluation includes a psychosocial assessment, conducted by social workers (SWs) on the advanced heart failure multidisciplinary team. Postdischarge caregiving plans are central to psychosocial evaluation. Caregiving's relationship with LVAD outcomes is mixed, and testing patients' social resources may disadvantage those from historically undertreated groups. We describe variation in policies defining adequate caregiving plans post-LVAD implant and possible impacts on patients from marginalized groups.

METHODS

This was a 2-phase sequential mixed-methods study: (1) phase 1, survey of US-based LVAD SWs, describing assessment structure and policies guiding candidacy outcomes; and (2) phase 2, individual interviews with SWs to further describe how caregiving plan adequacy impacts LVAD candidacy.

RESULTS

Sixty-seven SWs returned surveys (rr=47%) from unique programs. Caregiving plan inadequacy (n=30) was the most common psychosocial dealbreaker. When asked what duration of caregiving is required, 23% indicated ≥3 months, 27% 4 to 12 weeks, and 30% <4 weeks. Two reported no duration requirement, 6 stated an indefinite 24/7 commitment was necessary. Across 22 interviews, SWs mirrored that caregiving plans were the most common psychosocial contraindication. How caregiving is operationalized varied. Participants voiced a tension between extended caregiving improving outcomes and the sense that some people of color, women, or low socioeconomic status patients struggle to meet stringent requirements.

CONCLUSIONS

Policies regarding adequate duration of 24/7 caregiving vary, but inadequate caregiving plans are the most common psychosocial contraindication. Participants worry about patients' ability to meet restrictive requirements, particularly from historically undertreated groups. This highlights a need to operationalize quality caregiving, standardize assessment, and support medically appropriate patients with strained social resources.

Sex Differences in Recovery and Device Replacement After Left Ventricular Assist Device Implantation as Destination Therapy

Background The relevance of sex and preimplant factors for clinical outcomes among patients with left ventricular assist devices intended for destination therapy is unclear. Methods and Results INTERMACS (Interagency Registry for Mechanically Assisted Circulatory Support) data (2006-2017) from 6771 men and 1690 women with left ventricular assist devices as destination therapy were analyzed to evaluate the contribution of preimplant clinical, demographic, and clinically judged psychosocial characteristics to time until death, heart transplant, device explant due to recovery, or complication-related device replacement. Associations of sex with time until each competing outcome were evaluated using cumulative incidence functions and event-specific Cox proportional hazards models. Women were younger, more likely to have nonischemic diagnoses, and reported less substance abuse but were more likely to be unmarried, not working for an income, overweight, and depressed than men. After 2 years, women had higher probabilities for recovery (3.7% versus 1.6%, P<0.001) and device replacement (12.1% versus 10%, P=0.019) than men but not for death and transplant (P>0.12). The sex differences remained after controlling for covariates (adjusted hazard ratio [HR_adj] recovery, 1.85; 95% CI, 1.30-2.70; P<0.001; HR_adj device replacement, 1.22; 95% CI, 1.04-1.33; P=0.015). Female-specific diagnoses (eg, postpartum heart failure) contributed to women's enhanced rate of recovery. Demographic and psychosocial factors were unrelated to women's increased event rates. Conclusions In destination therapy, women have higher rates of device replacement and recovery than men. The latter was partly explained by female-specific diagnoses. Standardized assessments of psychosocial characteristics are needed to elucidate their association with sex differences in outcomes.

Recommendations for Psychosocial Evaluation of VAD candidates: Adoption, completion, and barriers to implementation

BACKGROUND

Recommendations exist to guide clinicians on a comprehensive psychosocial (PS) evaluation prior to Mechanical Circulatory Support (MCS) implantation.

OBJECTIVES

Assess adoption, beliefs, methodologies, and barriers to completion of the 2018 ISHLT/APM/AST/ICCAC/STSW Recommendations for Psychosocial evaluation of adult cardiothoracic transplant and long term mechanical circulatory support.

METHODS

Cross-sectional survey distributed to all 183 implanting LVAD centers in North America via mail and email.

RESULTS

Total of 58 Programs (35.6% response rate) representing 29 states and all regions of the United States responded. Respondents reported implanting 1,183 adults (range 0 - 85; mean = 21.5, SD = 18) in 2018. A majority (n = 55, 94.8%) reported that the 2018 Recommendations were consistent with their clinical practice and most (n = 51, 87.9%) had adopted the recommendations. The Stanford Integrated Psychosocial Assessment for Transplant (SIPAT) (n = 25, 47.1%) was the most commonly cited assessment tool in the use, although 15 centers reported utilizing more than one tool during the assessment process. Most common barriers influencing completion of the PS evaluation include patient too ill (total responses = 104), lack of time (total responses = 89), patient poor candidate (total responses = 44), and lack of Insurance coverage/reimbursement (total responses = 41).

CONCLUSION

The 2018 ISHLT Recommendations for PS evaluation of LVAD Candidates are widely adopted by respondents in clinical practice, although barriers are still reported to their implementation. Additional research is needed to understand strategies to reduce barriers to implementation and maintenance of the recommendations in clinical practice.

Gender differences in psychosocial and clinical characteristics in the European Registry for Patients with Mechanical Circulatory Support

BACKGROUND

Not much is known about psychosocial characteristics of men and women receiving continuous flow left ventricular assist devices (CF LVAD).

OBJECTIVE

To investigate gender differences in clinical and psychosocial (demographic, behavioral, psychological) characteristics in CF LVAD recipients.

METHODS

We analyzed European Registry for Patients with Mechanical Circulatory Support (EUROMACS) data (N=2395, 16.8% women; 2011 to 2017) and compared pre-implant characteristics in men and women intended for bridge-to-transplant (BTT) or destination therapy (DT).

RESULTS

Women were underrepresented [DT (n=61): 13.4%; BTT (n=341): 17.6%]. They were more likely to be divorced/separated, widowed, in unstable clinical condition, and non-working (DT only), but less likely to be smokers, to have ischemic cardiomyopathy or diabetes, and younger (BTT only) than men. Missing data were abundant, especially those that reflect psychological characteristics (>87%).

CONCLUSION

Gender differences were noted, some specific to device strategy. Improved collection of psychosocial characteristics is warranted to elucidate their relationship to future prognosis.
