Translation, adaptation, and reliability of the Stanford Integrated Psychosocial Assessment for Transplantation in the Spanish population

Assessing reliability and validity of SIPAT and opportunities for improvement: A single-center cohort study

Psychosocial assessment is a standard component of patient evaluations for transplant candidacy. The Stanford Integrated Psychosocial Assessment for Transplant (SIPAT) is a widely used measure to assess psychosocial risk for transplant. However, there are questions regarding the SIPAT's reliability and validity. We examined the SIPAT's psychometric performance and its impact on equitable access to transplant in a diverse cohort of 2825 patients seeking liver transplantation between 2014 and 2021 at an urban transplant center. The SIPAT demonstrated good internal consistency reliability at the overall score [Cronbach's α = 0.85, 95% CI (0.83, 0.86)] and domain levels (0.80 > α > 0.70). There was mixed support for structural validity, with poor overall model fit in confirmatory factor analysis and 50% of questions achieving the 0.70-factor loadings threshold. Adjusting for sociodemographic variables, the odds of not being waitlisted for psychosocial reasons were three times higher for patients with Medicaid insurance than patients with private insurance [OR 3.24, 95% CI (2.09, 4.99)] or Medicare [OR 2.89, 95% CI (1.84, 4.53)], mediated by higher SIPAT scores. Black patients had nearly twice the odds of White patients [OR 1.88, 95% CI (1.20, 2.91)], partially mediated by higher social support domain scores. Patients with Medicaid, non-White patients, and those without a college degree scored significantly higher on collinear questions, disproportionately contributing to higher SIPAT scores. The SIPAT did not perform equally across insurance type, race/ethnicity, and education groups, with the lowest subgroup validity associated with patient readiness and psychopathology domains. The SIPAT should be interpreted with caution, especially as a composite score. Future studies should examine validity in other populations.

Association of the Stanford Integrated Psychosocial Assessment for Transplant and 1-Year Outcome of Living Kidney Transplantation in Japan

BACKGROUND

Because most kidney transplantations in Japan are performed on the basis of living donors, after-transplant outcomes should achieve optimum results, overcoming participants' possible reduced adherence.

OBJECTIVE

To investigate the association between the Japanese version of the Stanford Integrated Psychosocial Assessment for Transplantation (SIPAT-J) and outcomes, 1 year after the patient's living kidney transplant (LKT).

METHODS

The prospective cohort study was undertaken at Tokyo Women's Medical University Hospital from January 2020 to July 2021, with a 1-year follow-up period. The SIPAT-J assesses 18 psychosocial risk factors: (1) Patient's Readiness Level and Illness Management (SIPAT A), (2) Social Support System Level of Readiness (SIPAT B), (3) Psychological Stability and Psychopathology (SIPAT C), and (4) Lifestyle and Effect of Substance Use (SIPAT D). The evaluators, a psychiatrist and 3 clinical psychologists, conducted an independent, blinded application of the SIPAT-J using participants' medical records. The study focused on physical composite outcomes, psychiatric outcomes, and nonadherent behaviors.

RESULTS

The participants were 173 LKT recipients (median age [interquartile range], 51 [38-59]); 67.1% were male and 67.1% were employed. The median (interquartile range) SIPAT scores were SIPAT A [7 (5-9)], SIPAT B [7 (5-9)], SIPAT C [2 (0-4)], SIPAT D [3 (3-4)], and SIPAT total [20 (16-23)]. The physical composite outcome was 25 (14.5%), psychiatric outcome 9 (5.2%), and nonadherent behavior 17 (9.8%). SIPAT C (odds ratio = 1.34, 95% confidence interval = 1.06-1.72, P = 0.02) was significantly associated with the psychiatric outcome. SIPAT B (odds ratio = 1.49, 95% confidence interval = 1.12-1.98, P = 0.01) and SIPAT total (odds ratio = 1.13, 95% confidence interval = 1.03-1.24, P = 0.01) were significantly associated with nonadherent behaviors. There was no significant association between the SIPAT and physical composite outcomes.

CONCLUSION

This study is the first to examine the association between SIPAT and physical and psychiatric outcomes 1 year after LKT, controlling for follow-up periods and factors other than SIPAT. Comprehensive psychosocial assessment before LKT and early identification of factors that may negatively affect transplant success can allow targeted interventions to be implemented and increase the likelihood of favorable recipient outcomes.

Characterization of the stanford integrated psychosocial assessment for transplant for heart, liver, and kidney transplant candidates in Japan

BACKGROUND

The Stanford Integrated Psychosocial Assessment for Transplantation (SIPAT) is a comprehensive psychosocial assessment proven useful for predicting the outcomes of organ transplantation that is expected to be useful in Japan. However, the characteristics of organ-specific SIPAT scores for organ transplant recipient candidates in Japan are unclear and, to date, the SIPAT has not been properly utilized in clinical practice. The purpose of this study was to present basic data that can be used to establish the relation between SIPAT scores and post-transplantation psychosocial outcomes as well as organ-specific outcomes.

METHODS

This study included 167 transplant recipient candidates (25 heart, 71 liver, and 71 kidney) who completed a semi-structured interview based on the Japanese version of SIPAT (SIPAT-J) prior to transplantation. The differences between organs in terms of SIPAT scores and differences in SIPAT scores based on demographic data were comparatively analyzed.

RESULTS

The total SIPAT scores were higher for liver recipient candidates than for heart recipient candidates (P = .019). Regarding the subscales, SIPAT B (social support system) scores were higher for liver and kidney recipient candidates than for heart recipient candidates (P = .021), whereas SIPAT C (psychological stability and psychopathology) scores were higher for liver recipient candidates than for kidney recipient candidates (P = .002). Recipient candidates with a history of psychiatric treatment and those who were unemployed had higher SIPAT scores, regardless of the transplant organ, than recipient candidates without a history of psychiatric treatment and those who were employed (P < .001, P = .016, respectively).

CONCLUSIONS

There were notable differences in the total SIPAT-J and subscale scores among the liver, heart, and kidney recipient candidates. Each organ was associated with specific psychosocial issues that should be addressed before transplantation. Interventions such as information provision and patient education based on SIPAT assessment results for each organ may improve recipient post-transplant outcomes.

Value of psychosocial evaluation for left ventricular assist device candidates

OBJECTIVE

Left ventricular assist devices require a psychosocial assessment to determine candidacy despite limited data correlating with outcome. Our objective is to determine whether the Stanford Integrated Psychosocial Assessment for Transplant, a tool validated for transplant and widely used by left ventricular assist device programs, predicts left ventricular assist device program hospital readmissions and death.

METHODS

We performed a retrospective analysis of adults at the Cleveland Clinic with Stanford Integrated Psychosocial Assessment for Transplant scores before primary left ventricular assist device program implantation from April 1, 2013, to December 31, 2018. The primary outcome was unplanned hospital readmissions censored at death, transplantation, and transfer of care. The secondary outcome was death.

RESULTS

There were 263 patients in the left ventricular assist device program with a median (Q1, Q3) Stanford Integrated Psychosocial Assessment for Transplant score of 16 (8, 28). During a median follow-up 1.2 years, 56 died, 65 underwent transplantation, and 21 had transferred care. There were 640 unplanned hospital readmissions among 250 patients with at least 1 outpatient visit at our center. In a multivariable analysis, Stanford Integrated Psychosocial Assessment for Transplant components but not total Stanford Integrated Psychosocial Assessment for Transplant score was associated with readmissions. Psychopathology (Stanford Integrated Psychosocial Assessment for Transplant C-IX) was associated with hemocompatibility (coefficient 0.21 ± standard error 0.11, P = .040) and cardiac (0.15 ± 0.065, P = .02) readmissions. Patient readiness was associated with noncardiac (Stanford Integrated Psychosocial Assessment for Transplant A-III, 0.24 ± 0.099, P = .016) and cardiac (Stanford Integrated Psychosocial Assessment for Transplant A-low total, 0.037 ± 0.014, P = .007) readmissions. Poor living environment (Stanford Integrated Psychosocial Assessment for Transplant B-VIII) was associated with device-related readmissions (0.83 ± 0.34, P = .014). Death was associated with organic psychopathology or neurocognitive impairment (Stanford Integrated Psychosocial Assessment for Transplant C-X, 0.59 ± 0.21, P = .006).

CONCLUSIONS

Total Stanford Integrated Psychosocial Assessment for Transplant score was not associated with left ventricular assist device program readmission or mortality. However, we identified certain Stanford Integrated Psychosocial Assessment for Transplant components that were associated with outcome and could be used to create a left ventricular assist device program specific psychosocial tool.

Psychosocial Assessment of Transplant Candidates: Inter-rater Reliability and Concurrent Validity of the Japanese Version of the Stanford Integrated Psychosocial Assessment for Transplantation

BACKGROUND

The Stanford Integrated Psychosocial Assessment for Transplantation (SIPAT) is a comprehensive instrument developed to provide a standardized, objective, and evidence-based psychosocial evaluation of the main pretransplant psychosocial risk factors that may influence transplant outcomes.

OBJECTIVE

Because established assessment procedures or standardized tools designed to perform pre-solid organ transplant psychosocial evaluation are currently unavailable in Japan, the present study aimed to develop and preliminarily validate the Japanese version of the SIPAT.

METHODS

First, the Japanese version of the SIPAT was developed using standard forward-back-translation procedures. Then, the Japanese versions of the SIPAT and the Japanese version of Psychosocial Assessment of Candidates for Transplant were retrospectively and blindly applied to 107 transplant cases by 4 independent raters.

RESULTS

The interrater reliability of the scores obtained with the Japanese version of the SIPAT was excellent (Pearson's correlation coefficient = 0.86). The concurrent validity of the SIPAT to the Psychosocial Assessment of Candidates for Transplant for each examiner was substantial (Spearman's rank correlation coefficient = -0.66).

CONCLUSION

These findings suggest that the Japanese version of the SIPAT is a promising and reliable instrument. Further research is required to test the predictive validity of the Japanese version of the SIPAT.

The Psychosocial Assessment of Transplant Candidates: Internal Consistency, Interrater Reliability, and Content Validity of the Thai Version of the Stanford Integrated Psychosocial Assessment for Transplantation (SIPAT-Thai Version)

BACKGROUND

Standardized pretransplant psychosocial assessment is critically needed in Thailand to optimize medical and psychosocial outcomes after transplantation. The Stanford Integrated Psychosocial Assessment for Transplantation (SIPAT) is a comprehensive and evidence-based tool that has demonstrated excellent reliability and predictive value in many psychosocial transplant studies. We translated the SIPAT into Thai and explored the validity and reliability of the SIPAT-Thai version among Thai transplant recipients.

METHODS

We translated the original SIPAT into Thai following the World Health Organization's standard forward-backward translation procedure and then cross-sectionally assessed its validity and reliability in 110 Thai solid organ transplant candidates. The correlation between background data, total, and sectional scoring results of SIPAT-Thai were also analyzed.

RESULTS

The SIPAT-Thai demonstrated moderate to good reliability, which was represented by internal consistency with a Cronbach α of .751 and interrater reliability with a κ value at 0.767. The index of item-objective congruence value was 0.94, indicating good the content validity.

CONCLUSIONS

The SIPAT-Thai was systematically translated and shown to have acceptable validity and a moderate to good reliability index. The use of the SIPAT-Thai would provide a standardized, evidence-based, and a more systematic pretransplant psychosocial evaluation process for transplant candidates in Thailand.

Factors Affecting Quality of Life in Liver Transplant Candidates: An Observational Study

Health-related quality of life (HRQOL) before and after liver transplant (LT) is an important outcome in LT candidates as, in these patients, HRQOL is commonly impaired. However, evidence regarding factors that influence HRQOL in patients with end-stage liver disease is inconclusive. The aim of the present study was to identify factors associated with poor HRQOL. An observational study was conducted over LT candidates. The 36-item Short Form Health Survey (widely used to assess HRQOL) and the Hospital Anxiety and Depression Scale were administered to 211 patients during the pre-transplant assessment. Baseline demographic and clinical data were also collected. Multiple regression analysis was performed to investigate risk factors for poor HRQOL. Female sex (lower B = 7.99 95%C = 0.07–15.92, higher B = 18.09 95%CI = 7.56–28.62), encephalopathy (lower B = −9.45, 95%CI = −14.59–−4.31, higher B = −6.69, 95%CI = −13.13 to −0.25), higher MELD scores (lower B = −1.14, 95%CI = −1.67 to −0.61, higher B = −0.33, 95%CI = −0.65 to −0.12), anxiety (lower B = −3.04 95%C = −4.71 to −1.36, higher B = −1.93 95%CI = −3.39 to −0.47)and depression (lower B = −3.27 95%C = −4.46 to −2.08, higher B = −1.02 95%CI = −1.90 to −0.13) symptoms were associated to poorer HRQOL. Psychosocial interventions should be addressed to liver transplant candidates, especially to women, patients with anxiety, depression or episodes of encephalopathy, in order to prevent the impact that these conditions can have on HRQOL.

Epistemic Authority and Trust in Shared Decision Making About Organ Transplantation

Patient epistemic authority acknowledges respect for a patient's knowledge claims, an important manifestation of patient autonomy that facilitates shared decision making in medicine. Given the scarcity of deceased donor organs, transplantation programs state that patient promises of compliance cannot be taken at face value and exclude candidates deemed untrustworthy. This article argues that transplant programs frequently lack the data to make this utilitarian calculation accurately, with the result that, in practice, the psychosocial evaluation of potential transplant candidates is discriminatory and unfair. Historically excluded candidates, such as patients suffering from alcohol use, have turned out to benefit highly from transplantation. Transplant programs should tend to trust patients when they claim to be good potential organ stewards, thereby respecting patient autonomy, advancing justice, and saving more lives.
