RESUMEN

OBJECTIVES: Examine family safety-reporting after implementing a parent-nurse-physician-leader coproduced, health literacy-informed, family safety-reporting intervention for hospitalized families of children with medical complexity. METHODS: We implemented an English and Spanish mobile family-safety-reporting tool, staff and family education, and process for sharing comments with unit leaders on a dedicated inpatient complex care service at a pediatric hospital. Families shared safety concerns via predischarge surveys (baseline and intervention) and mobile tool (intervention). Three physicians with patient safety expertise classified events. We compared safety-reporting baseline (via survey) versus intervention (via survey and/or mobile tool) with generalized estimating equations and sub-analyzed data by COVID-19-era and educational attainment. We also compared mobile tool-detected event rates with hospital voluntary incident reporting. RESULTS: 232 baseline and 208 intervention parents participated (78.2% consented); 29.5% of baseline families versus 38.2% of intervention families reported safety concerns (P = .09). Adjusted odds ratio (95% CI) of families reporting safety concerns intervention versus baseline was 1.6 (1.0-2.6) overall, 2.6 (1.3-5.4) for those with < college education, and 3.1 (1.3-7.3) in the COVID-19-era subgroup. Safety concerns reported via mobile tool (34.6% of enrolled parents) included 42 medical errors, 43 nonsafety-related quality issues, 11 hazards, and 4 other. 15% of mobile tool concerns were also detected with voluntary incident reporting. CONCLUSIONS: Family safety-reporting was unchanged overall after implementing a mobile reporting tool, though reporting increased among families with lower educational attainment and during the COVID-19 pandemic. The tool identified many events not otherwise captured by staff-only voluntary incident reporting. Hospitals should proactively engage families in reporting to improve safety, quality, and equity.

RESUMEN

Many social cognitive assessments that were developed specifically for use in clinical populations are now being widely used in undergraduate populations, either to provide a comparison for clinical groups or to explore performance across the continuum from healthy to subclinical populations. However, the appropriateness of using these assessments in the general population is unclear. The current study, therefore, seeks to determine whether the Social Cognition Psychometric Evaluation (SCOPE) battery retains its psychometric properties when used in an undergraduate sample.The initial SCOPE battery was administered to 265 undergraduate participants, and the utility of the tasks was measured by assessing floor and ceiling effects. Internal consistency, discriminant and convergent validity are reported for each task, and the relationship between task performance and neurocognition and social functioning were assessed.Several of the tasks demonstrated limited utility, with the Hinting Task specifically demonstrating a pronounced ceiling effect. Only two measures of social cognitive biases achieved satisfactory internal consistency. Select tasks demonstrated small, but significant relationships with social functioning outcomes and significantly predicted 2-3% of variance above neurocognition alone.Despite the association with social functioning, results indicate that the psychometric properties demonstrated in the initial SCOPE study with a clinical sample do not fully extend to a healthy undergraduate population and highlight the need for social cognitive tasks that validly assess ability across the continuum.

RESUMEN

BACKGROUND AND HYPOTHESIS: Social cognitive impairments are central to psychosis, including lower severity psychosis-like experiences (PLEs). Nonetheless, progress has been hindered by social cognition's poorly defined factor structure, as well as limited work examining the specificity of social cognitive impairment to psychosis. The present study examined how PLEs relate to social cognition in the context of other psychopathology dimensions, using a hierarchical factors approach to social cognition. STUDY DESIGN: Online community participants (N = 1026) completed psychosis, autism, and personality disorder questionnaires, as well as 3 social cognitive tasks that varied in methodology (vignette vs video) and construct (higher- vs lower-level social cognition). Exploratory (EFA) and confirmatory factor analyses (CFA) were used to model social cognition, with the best models being examined in association with PLEs and psychopathology dimensions. STUDY RESULTS: EFA and CFA supported a hierarchical model of social cognition, with 2 higher-order factors emerging: verbal/vignette task methodology and a multimethod general social cognition factor. These higher-order factors accounted for task-level associations to psychopathology, with relations to positive symptoms (r = .23) and antagonism (r = .28). After controlling for other psychopathology, positive symptoms were most clearly related to tasks with verbal methodology (ß = -0.34). CONCLUSIONS: These results suggest that broad social cognitive processes and method effects may account for many previous findings in psychosis and psychopathology research. Additionally, accounting for broad social cognitive impairment may yield insights into more specific social cognitive processes as well.

RESUMEN

Background: Paranoia is a spectrum of fear-related experiences that spans diagnostic categories and is influenced by social and cognitive factors. The extent to which social media and other types of media use are associated with paranoia remains unclear. Objective: We aimed to examine associations between media use and paranoia at the within- and between-person levels. Methods: Participants were 409 individuals diagnosed with schizophrenia spectrum or bipolar disorder. Measures included sociodemographic and clinical characteristics at baseline, followed by ecological momentary assessments (EMAs) collected 3 times daily over 30 days. EMA evaluated paranoia and 5 types of media use: social media, television, music, reading or writing, and other internet or computer use. Generalized linear mixed models were used to examine paranoia as a function of each type of media use and vice versa at the within- and between-person levels. Results: Of the 409 participants, the following subgroups reported at least 1 instance of media use: 261 (63.8%) for using social media, 385 (94.1%) for watching TV, 292 (71.4%) for listening to music, 191 (46.7%) for reading or writing, and 280 (68.5%) for other internet or computer use. Gender, ethnoracial groups, educational attainment, and diagnosis of schizophrenia versus bipolar disorder were differentially associated with the likelihood of media use. There was a within-person association between social media use and paranoia: using social media was associated with a subsequent decrease of 5.5% (fold-change 0.945, 95% CI 0.904-0.987) in paranoia. The reverse association, from paranoia to subsequent changes in social media use, was not statistically significant. Other types of media use were not significantly associated with paranoia. Conclusions: This study shows that social media use was associated with a modest decrease in paranoia, perhaps reflecting the clinical benefits of social connection. However, structural disadvantage and individual factors may hamper the accessibility of media activities, and the mental health correlates of media use may further vary as a function of contents and contexts of use.

RESUMEN

Negative symptoms are a source of disability in schizophrenia, but criteria for identifying patients for clinical trials are in flux. Minimum severity for negative symptoms is paired with a definition of minimal psychosis to identify predominant negative symptoms. Two previous successful negative symptoms treatment studies used very different severity and selection criteria. We compared the prevalence of participants meeting those two criteria in a large outpatient sample of participants with schizophrenia. Data from 867 outpatients with schizophrenia who participated in one of four NIMH-funded studies were analyzed. Common data elements included diagnoses, the PANSS, and an assessment of everyday functioning. We compared previous criterion for premoninant negative symptoms based on low levels of agitation and psychosis and different cut-offs for negative symptoms severity. 57 % of the participants met the agitation-based criteria for low scores and 33 % met the psychosis-based criteria. 18 % met total PANSS score ≥ 20 and 8 % met ≥24 prominent negative symptoms criteria. 14 % met low agitation and PANSS≥20 and 2 % met the low psychosis and negative symptoms ≥24 criteria. Participants who met all predominant criteria had more impairments in social functioning (all p < .001, all d > 0.37). Criteria for predominant negative symptoms from previous clinical trials identify widely different numbers of cases, with criteria for negative symptom severity and low symptoms both impacting. All criteria yield the expected profile of relatively specific social deficits. Even in unselected populations who participated in complex research protocols, 14 % meet low- agitation based criteria for predominant negative symptoms and many more participants would be expected to meet criteria with enrichment for the presence of negative symptoms.

RESUMEN

BACKGROUND AND HYPOTHESIS: Psychotic-like experiences (PLEs) are prevalent in the general population and, because they represent a lower end of the psychosis vulnerability spectrum, may be useful in informing mechanistic understanding. Although it is well-understood that motor signs characterize formal psychotic disorders, the developmental trajectory of these features and their relationships with PLEs are less well-understood. STUDY DESIGN: Data from 7559 adolescents and young adults (age 11-21) in the Philadelphia Neurodevelopmental Cohort were used to investigate whether early-life milestone-attainment delays relate to current adolescent sensorimotor functioning and positive and negative PLEs. Current sensorimotor functioning was assessed using the Computerized Finger Tapping task (assessing motor slowing) and Mouse Practice task (assessing sensorimotor planning). STUDY RESULTS: Early developmental abnormalities were related to current adolescent-aged motor slowing (t(7415.3) = -7.74, corrected-P < .001) and impaired sensorimotor planning (t(7502.5) = 5.57, corrected-P < .001). There was a significant interaction between developmental delays and current sensorimotor functioning on positive and negative PLEs (t = 1.67-4.51), such that individuals with early developmental delays had a stronger positive relationship between sensorimotor dysfunction and PLEs. Importantly, interaction models were significantly better at explaining current PLEs than those treating early and current sensorimotor dysfunction independently (χ2 = 4.89-20.34). CONCLUSIONS: These findings suggest a relationship between early developmental delays and current sensorimotor functioning in psychosis proneness and inform an understanding of heterotypic continuity as well as a neurodevelopmental perspective of motor circuits. Furthermore, results indicate that motor signs are a clear factor in the psychosis continuum, suggesting that they may represent a core feature of psychosis vulnerability.

RESUMEN

BACKGROUND: Despite high rates of suicide among people with psychosis, relatively little is known about the mechanisms underlying the transition from suicidal ideation to behavior in this population. The Interpersonal Psychological Theory of Suicide (IPTS) proposes that fearlessness about death (FAD) may play a role in this relationship. The present study tested whether constructs of the IPTS [thwarted belongingness (TB), perceived burdensomeness (PB), and FAD] were associated with the severity of suicidal ideation in a sample of adults with histories of psychosis. METHOD: 261 adults with histories of psychosis completed measures of IPTS constructs, current severity of suicidal ideation, and history of suicidal attempts. We examined differences between those with past suicide attempts and those without and conducted regression analyses to evaluate the associations among TB, PB, FAD and severity of current suicidal ideation. RESULTS: Contrary to expectations, a history of suicidal behavior was not uniquely associated with FAD. Regression analyses revealed TB × PB and FAD × PB interactions emerged as significant correlates of the severity of suicidal ideation, with the relationship between PB and suicidal ideation more pronounced at higher levels of FAD and TB. Interestingly, positive symptoms of psychosis were positively associated with PB. IMPLICATIONS: This study provides support for broadening the investigation of FAD as a contributor to suicidal ideation in individuals with psychotic symptoms. Future research investigating the role of other contributors that may influence capability for suicide (e.g., impulsivity) may add additional understanding of suicide in this population.

RESUMEN

Background and Hypothesis: People with serious mental illness (SMI; psychotic and affective disorders with psychosis) are at an increased risk of suicide, yet there is limited research on the correlates of suicide in SMI. Social cognitive impairments are common among people with SMI and several studies have examined social cognition and suicidal ideation (SI) and behavior. This systematic review aims to evaluate the links between various domains of social cognition, SI, and suicidal behavior in SMI. Study Design: Electronic databases (PubMed and PsycInfo) were searched through June 2023. Records obtained through this search (N = 618) were screened by 2 independent reviewers according to inclusion criteria. Relevant data were extracted, and study quality was assessed. Study Results: Studies (N = 16) from 12 independent samples were included in the systematic review (N = 2631, sample sizes ranged from N = 20 to N = 593). Assessments of social cognition and SI and behavior varied widely between studies. Broadly, effects were mixed. Better emotion recognition of negative affect was linked to SI and a history of suicide attempts, though there is little consistent evidence for the relationship of emotion recognition and SI or behavior. On the other hand, better theory of mind ability was linked to SI and a history of suicide attempts. Furthermore, negative attributional bias was linked to current SI, but not a history of SI or attempt. Conclusions: This review suggests mixed associations between social cognition, SI, and behavior in SMI. Future research should evaluate additional mediators and moderators of social cognition and suicide, employing prospective designs.

RESUMEN

Neurosciences clinical trials continue to have notoriously high failure rates. Appropriate outcomes selection in early clinical trials is key to maximizing the likelihood of identifying new treatments in psychiatry and neurology. The field lacks good standards for designing outcome strategies, therefore The Outcomes Research Group was formed to develop and promote good practices in outcome selection. This article describes the first published guidance on the standardization of the process for clinical outcomes in neuroscience. A minimal step process is defined starting as early as possible, covering key activities for evidence generation in support of content validity, patient-centricity, validity requirements and considerations for regulatory acceptance. Feedback from expert members is provided, regarding the risks of shortening the process and examples supporting the recommended process are summarized. This methodology is now available to researchers in industry, academia or clinics aiming to implement consensus-based standard practices for clinical outcome selection, contributing to maximizing the efficiency of clinical research.

RESUMEN

Response times (RTs) to ecological momentary assessment (EMA) items often decrease after repeated EMA administration, but whether this is accompanied by lower response quality requires investigation. We examined the relationship between EMA item RTs and EMA response quality. In one data set, declining response quality was operationalized as decreasing correspondence over time between subjective and objective measures of blood glucose taken at the same time. In a second EMA study data set, declining response quality was operationalized as decreasing correspondence between subjective ratings of memory test performance and objective memory test scores. We assumed that measurement error in the objective measures did not increase across time, meaning that decreasing correspondence across days within a person could be attributed to lower response quality. RTs to EMA items decreased across study days, while no decrements in the mean response quality were observed. Decreasing EMA item RTs across study days did not appear problematic overall.

RESUMEN

There is a general consensus that personality disorders (PDs) share a general factor (g-PD) overlapping with the general factor of psychopathology (p-factor). The general psychopathology factor is related to many social dysfunctions, but its nature still remains to some extent ambiguous. We posit that hostile attributions may be explanatory for the factor common for all PDs, i.e., interpersonal problems and difficulty in building long-lasting and satisfying relationships of all kinds. Thus, the main objective of the current project was to expand the existing knowledge about underlying factors of g-PD with regard to hostile attributions. We performed a cross-sectional study on a representative, community sample of Poles (N = 1031). Our hypotheses were primarily confirmed as hostile attributions predicted p-factor. However, the relation was positive only for hostile attributions related to ambiguous situations involving relational harm and physical harm done by female authorities and negative in case of hostile attributions in situations involving physical harm done by peers. Additionally, paranoia-like thoughts strongly related to hostile attributions and independently predicted g-PD. The results contribute to the current discussion on the nature of the g-PD, confirm that hostile attributions and paranoia are a crucial aspect of personality pathology, and indicate the importance of working on these cognitions in the course of therapeutic work.

RESUMEN

People with serious mental illness have challenged self-awareness, including momentary monitoring of performance. A core feature of this challenge is in the domain of using external information to guide behavior, an ability that is measured very well by certain problem-solving tasks such as the Wisconsin Card Sorting Test (WCST) . We used a modified WCST to examine correct sorts and accuracy decisions regarding the correctness of sort. Participants with schizophrenia (n = 99) or bipolar disorder (n = 76) sorted 64 cards and then made judgments regarding correctness of each sort prior to feedback. Time series analyses examined the course of correct sorts and correct accuracy decisions by examining the momentary correlation and lagged correlation on the next sort. People with schizophrenia had fewer correct sorts, fewer categories, and fewer correct accuracy decisions (all p<.001). Positive response biases were seen in both groups. After an incorrect sort or accuracy decision, the groups were equally likely to be incorrect on the next sort or accuracy decision. Following correct accuracy decisions, participants with bipolar disorder were significantly (p=.003) more likely to produce a correct sort or accuracy decision. These data are consistent with previous studies implicating failures to consider external feedback for decision making. Interventions aimed at increasing consideration of external information during decision making have been developed and interventions targeting use of feedback during cognitive test performance are in development.

RESUMEN

Deficits in facial identity recognition and its association with poor social functioning are well documented in schizophrenia, but none of these studies have assessed the role of the body in these processes. Recent research in healthy populations shows that the body is also an important source of information in identity recognition, and the current study aimed to thoroughly examine identity recognition from both faces and bodies in schizophrenia. Sixty-five individuals with schizophrenia and forty-nine healthy controls completed three conditions of an identity matching task in which they attempted to match unidentified persons in unedited photos of faces and bodies, edited photos showing faces only, or edited photos showing bodies only. Results revealed global deficits in identity recognition in individuals with schizophrenia (ηp2 = 0.068), but both groups showed better recognition from bodies alone as compared to faces alone (ηp2 = 0.573), suggesting that the ability to extract useful information from bodies when identifying persons may remain partially preserved in schizophrenia. Further research is necessary to understand the relationship between face/body processing, identity recognition, and functional outcomes in individuals with schizophrenia-spectrum disorders.

RESUMEN

People with schizophrenia-spectrum and bipolar disorders have difficulty accurately estimating their abilities and skills (impaired introspective accuracy [IA]) and tend to over- or underestimate their performance. This discrepancy between self-reported and objective task performance has been identified as a significant predictor of functional impairment. Yet, the factors driving this discrepancy are currently unclear. To date, the relationships between sleep quality and IA have not been examined. The current study aimed to explore the relationships between sleep quality and IA in participants diagnosed with schizophrenia (SCZ; n = 36), schizoaffective disorder (SCZ-A; n = 55), and bipolar disorder with psychotic features (BP; n = 87). Participants completed tasks of emotion recognition, estimated their performance on the tasks (used to calculate IA), and provided confidence ratings for their accuracy judgments. Participants also self-reported their sleep quality. These results suggest significantly greater discrepancies between self-reported and actual task scores for those with SCZ and SCZ-A compared to participants with BP. For those with SCZ, lower confidence on the tasks and underestimation of abilities were associated with lower sleep quality, while for those with SCZ-A, lower sleep quality was associated with higher confidence and overestimation of performance. Results suggest differential relationships between diagnostic groups. Future research is needed to further explore the factors driving these differing relationships, particularly the contrasting relationships between SCZ and SCZ-A.

RESUMEN

INTRODUCTION: People with serious mental illness (SMI; schizophrenia, schizoaffective disorder, bipolar disorder) are at increased risk of suicidal ideation (SI). Over-attribution of social threat, or attributing threatening emotions to neutral faces, may contribute to social isolation through increased social avoidance and decreased social approach motivation. These factors are related to suicide, as well as perceived burdensomeness (PB) and thwarted belongingness (TB). This study examined how over-attribution of threat relates to PB, TB, and social motivations. METHOD: N = 273 participants with SMI were assessed for current SI and behavior, and were stratified into SI (N = 130) vs. non-SI (N = 143) groups. Participants completed smartphone surveys (via ecological momentary assessments [EMA]) 3×/day for 10 days. They also completed the Mobile Ecological Test of Emotion Recognition (METER) 1×/day. Linear mixed models and multi-level mediation tested the relationships between over-attribution of threat, METER performance, PB/TB, and social motivations. RESULTS: Participants with and without SI did not significantly differ in over-attribution of threat or METER performance. In separate models, there was a relationship of over-attribution of threat with increased PB (B = 1.00, SE = 0.21, t = 4.72, p < .001), reduced social approach motivation (B = -0.74, SE = 0.22, t = -3.33, p < .001), and increased social avoidance (B = 0.90, SE = 0.24, t = 3.70, p < .001), all significant when adjusting for facial affect recognition ability. A model examining social motivations as a mediator between over-attribution of threat and PB/TB was not significant. CONCLUSION: These results suggest that over-attribution of threat relates to interpersonal constructs related to SI irrespective of facial affect abilities. This study may inform understanding of social cognitive processes related to suicide in SMI.

RESUMEN

Little is known about central nervous system (CNS) responses to emotional stimuli in asthma. Nitric oxide in exhaled breath (FENO) is elevated in asthma due to allergic immune processes, but endogenous nitric oxide is also known to modulate CNS activity. We measured fMRI blood oxygen-dependent (BOLD) brain activation to negative (blood-injection-injury themes) and neutral films in 31 participants (15 with asthma). Regions-of-interest analysis was performed on key areas relevant to central adaptive control, threat processing, or salience networks, with dorsolateral prefrontal cortex (PFC), anterior insula, dorsal anterior cingulate cortex (dACC), amygdala, ventral striatum, ventral tegmentum, and periaqueductal gray, as well as top-down modulation of emotion, with ventrolateral and ventromedial PFC. Both groups showed less BOLD deactivation from fixation cross-baseline in the left anterior insula and bilateral ventromedial PFC for negative than neutral films, and for an additional number of areas, including the fusiform gyrus, for film versus recovery phases. Less deactivation during films followed by less recovery from deactivation was found in asthma compared to healthy controls. Changes in PCO2 did not explain these findings. FENO was positively related to BOLD activation in general, but more pronounced in healthy controls and more likely in neutral film processing. Thus, asthma is associated with altered processing of film stimuli across brain regions not limited to central adaptive control, threat processing, or salience networks. Higher levels of NO appear to facilitate CNS activity, but only in healthy controls, possibly due to allergy's masking effects on FENO.

RESUMEN

BACKGROUND: Autism and psychosis co-occur at elevated rates, with implications for clinical outcomes, functioning, and suicidality. The PANSS-Autism-Severity-Score (PAUSS) is a measure of autism trait severity which has not yet been validated externally or longitudinally. STUDY DESIGN: Participants were derived from the GROUP and SCOPE datasets. Participants included 1448 adults with schizophrenia spectrum disorder (SSD), 800 SSD-siblings, 103 adults diagnosed with an autistic spectrum condition (ASC), and 409 typically-developing controls (TC). Analyses from the original validation study were conducted with SSD participants, and extended into ASC, SSD-sibling, and TC participants. Test-retest reliability of the PAUSS at 2-weeks and long-term stability 3 and 6-years was also examined. STUDY RESULTS: Results differed in important ways from the original validation. SSD participants reported higher PAUSS scores than other groups, with only a fraction of ASC participants scoring as "PAUSS-Autistic." Cronbach's alpha was acceptable for the SSD cohort only. Two-week stability of the PAUSS was fair to good for all PAUSS scores. Long-term stability was poor for most PAUSS items but fair for total PAUSS score. CONCLUSIONS: Results suggest that the PAUSS does not appear appropriate for assessing autism, with the low rate of PAUSS-Autistic in the ASC population suggesting the PAUSS may not accurately reflect characteristics of autism. The relative lack of long-term stability is cause for concern and suggestive that the PAUSS is capturing features of psychosis rather than autism traits.

RESUMEN

INTRODUCTION: The study explored associations between the accuracy of post assessment judgements of cognitive performance with global self-assessments of psychosocial functioning compared to evaluations generated by observers in schizophrenia and bipolar disorder. METHODS: An abbreviated cognitive assessment based on the MATRICS Consensus Cognitive Battery was administered to 122 individuals with schizophrenia and 113 with bipolar disorder. They provided self-estimates of their performance after each subtest. In addition, self-reports on cognition, social cognition, and everyday functioning were collected and compared to observer ratings. RESULTS: Both groups overestimated their cognitive function, but in bipolar disorder, there was 30% shared variance between task performance and self-rated task performance (vs. 5% in schizophrenia). Significant correlations were found between self-reported everyday outcomes and both actual and self-assessed performance. In schizophrenia, immediate judgements were only related to self-rated functioning, not to observer rated functioning. In bipolar disorder, impairments in self-assessment of performance correlated with observer ratings of cognitive ability, which was not observed in schizophrenia. CONCLUSIONS: While both groups showed correlations between cognitive performance and introspective accuracy, individuals with bipolar disorder showed higher accuracy in assessing their cognitive performance and other outcomes. Notably, impairments in introspective accuracy were associated with observer-rated functioning exclusively in bipolar disorder.

RESUMEN

BACKGROUND: Some research suggests that schizotypal and autistic traits can produce opposing effects on the mentalizing domain of social cognition. Although such findings support a diametrical model proposing that psychotic and autistic traits represent opposite extremes of the social brain continuum, results from recent studies have been more inconsistent, and the applicability of this model to other social cognition domains remains unclear. To test the diametrical model more broadly, this study examined the interactions between schizotypal and autistic traits on emotion recognition and social functioning. METHOD: A total of 791 participants recruited from the general population self-reported schizotypal traits using the Schizotypal Personality Questionnaire-Brief Revised (SPQ-BR) and autistic traits using the Broad Autism Phenotype Questionnaire (BAPQ). Participants also completed the Emotion Recognition 40 task and the Specific Levels of Functioning (SLOF) scale. RESULTS: The SPQ subscales of interpersonal relationships and disorganized symptoms interacted significantly with social BAP on overall emotion recognition performance and the accuracy of identifying neutral faces. Supporting the diametrical model, elevated levels of both schizotypal and autistic traits contributed to higher emotion recognition accuracy compared to elevations on only one trait. For social functioning, however, the diametrical model was not supported. A main effect was found such that higher interpersonal relationship difficulties on SPQ predicted lower work skills on SLOF, and higher levels of both schizotypal and autistic traits combined to produce even lower social functioning. CONCLUSIONS: These findings suggest that the diametrical model may be more relevant to social cognition than to social functioning.

RESUMEN

OBJECTIVES: Prior research suggests that errors occur frequently for patients with medical complexity during the hospital-to-home transition. Less is known about effective postdischarge communication strategies for this population. We aimed to assess rates of 30-day (1) postdischarge incidents and (2) readmissions and emergency department (ED) visits before and after implementing a hospital-to-home intervention. METHODS: We conducted a prospective intervention study of children with medical complexity discharged at a children's hospital from April 2018 to March 2020. A multistakeholder team developed a bundled intervention incorporating the I-PASS handoff framework including a postdischarge telephone call, restructured discharge summary, and handoff communication to outpatient providers. The primary outcome measure was rate of postdischarge incidents collected via electronic medical record review and family surveys. Secondary outcomes were 30-day readmissions and ED visits. RESULTS: There were 199 total incidents and the most common were medication related (60%), equipment issues (15%), and delays in scheduling/provision of services (11%). The I-PASS intervention was associated with a 36.4% decrease in the rate of incidents per discharge (1.51 versus 0.95, P = 0.003). There were fewer nonharmful errors and quality issues after intervention (1.27 versus 0.85 per discharge, P = 0.02). The 30-day ED visit rate was significantly lower after intervention (12.6% versus 3.4%, per 100 discharges, P = 0.05). Thirty-day readmissions were 15.8% versus 10.2% postintervention (P = 0.32). CONCLUSIONS: A postdischarge communication intervention for patients with medical complexity was associated with fewer postdischarge incidents and reduced 30-day ED visits. Standardized postdischarge communication may play an important role in improving quality and safety in the transition from hospital-to-home for vulnerable populations.
