This narrative review was based on a structured literature search of PubMed/MEDLINE, Web of Science Core Collection, CINAHL, China National Knowledge Infrastructure (CNKI), and Wanfang Data from database inception to August 31, 2026. Searches addressed four concepts: hematopoietic stem cell transplantation (HSCT), protective isolation or laminar airflow clean rooms, emotional or psychological states, and nursing or psychosocial interventions. Representative English terms included “hematopoietic stem cell transplantation,” “HSCT,” “protective isolation,” “laminar airflow ward,” “laminar airflow clean room,” “anxiety,” “depression,” “psychological distress,” “emotional state,” “psychological assessment,” “distress screening,” “assessment instrument,” “nursing intervention,” “psychological intervention,” and “social support.” Corresponding Chinese terms were used in Chinese databases, and reference lists of relevant publications were screened for additional studies.
English- or Chinese-language publications were considered if they involved HSCT patients and addressed emotional or psychological states, temporal emotional changes, factors associated with psychological distress, assessment instruments, or nursing and psychosocial interventions relevant to HSCT or protective isolation. Studies that did not involve HSCT patients or did not address relevant psychological or emotional outcomes were excluded. Titles and abstracts were screened first, followed by full-text assessment.
For the conceptual framework, recurrent factors were grouped into environmental isolation, physical symptoms, biological mechanisms, information deficits, and social and family support; demographic and clinical characteristics were considered contextual modifiers. Evidence was synthesized narratively by emotional state evolution, contributing factors, and nursing adjustment measures, rather than quantitatively pooled.
Evolution of emotional states across the HSCT trajectory
Psychological distress is common during HSCT, although its manifestations and intensity vary across treatment phases. Martynowicz et al3 reported depression in 15%–40%, anxiety in 20%–52%, and post-traumatic stress disorder (PTSD) in 19%–28% of HSCT patients. Differences in populations, transplantation types, assessment instruments, and time points limit direct comparison. Consequently, the following patterns represent commonly reported phase-related tendencies rather than a uniform trajectory.
Pre-transplantation and entry into protective isolation
The pre-transplantation period and entry into protective isolation are frequently associated with anticipatory anxiety and uncertainty concerning conditioning, complications, transplantation outcomes, prolonged hospitalization, and separation from usual social networks. Amonoo et al5 identified anxiety and uncertainty as important concerns during early HSCT, particularly in relation to treatment toxicities and uncertain outcomes.
In a longitudinal study of 82 HSCT patients, Qin et al6 found that anxiety was highest around the time of entry into the laminar airflow room and subsequently decreased. Information-related problems may intensify this distress. Chen et al7 identified difficulties obtaining reliable information and managing diverse or overwhelming online information among patients in laminar airflow rooms.
Negative and positive emotions can coexist. Mohamadifard et al8 described both fears concerning transplantation and hope for recovery or cure. Thus, this phase may involve anxiety, uncertainty, high information needs, fear, and hope.
Conditioning and early post-transplant period
During conditioning and early post-transplantation, psychological distress becomes closely associated with treatment-related symptoms. Nausea, vomiting, mucositis, fatigue, pain, loss of appetite, sleep disturbance, and other adverse effects may reduce perceived control and increase concerns about treatment tolerance and outcomes.
Amonoo et al5 described early HSCT hospitalization as involving treatment uncertainty, physical symptoms, and psychological stress. Martynowicz et al3 similarly emphasized interactions between physical and mental health and noted that severe symptoms may restrict participation in conventional psychological interventions. Increasing dependence on healthcare professionals for monitoring, medication, information, personal care, and reassurance may further affect emotional well-being.
Aplasia/Myelosuppression and prolonged isolation
Aplasia or myelosuppression may be particularly challenging. Qin et al6 found that depressive symptoms increased and subsequently decreased, reaching their highest levels during post-chemotherapy myelosuppression. Fatigue, nausea, impaired functioning, infection risk, and prolonged separation from family may occur simultaneously.
Liu et al9 synthesized 18 qualitative studies and identified negative psychological experiences, positive psychological experiences, supportive needs, and post-transplant adjustment as major domains of the HSCT experience. Lee and Halliday2 reported social disconnection, loss of control, and negative emotions during protective isolation, while Amonoo et al10 identified fear, discouragement, powerlessness, and feeling trapped. This phase may therefore involve depression, anxiety, loneliness, helplessness, emotional fluctuation, and reduced motivation, although individual experiences vary.
Engraftment and early recovery
Psychological distress may persist despite hematologic recovery because fatigue, weakness, uncertainty, and concerns about complications can continue. Nevertheless, improvement in acute symptoms may be accompanied by increasing relief and optimism.
Amonoo et al11 examined positive psychological experiences during hospitalization and approximately 100 days after allogeneic HSCT. Patients reported gratitude, determination, optimism, hope for a cure, and a desire to regain previous functioning. Family relationships, social support, and meaningful activities were also important. Thus, engraftment may involve increasing hope and independence, although positive and negative emotions can coexist, and psychological recovery may not parallel hematologic recovery.
Discharge and early post-transplant transition
Discharge transfers greater responsibility for symptom monitoring, medication, infection prevention, nutrition, and self-care to patients. Although it signals recovery and independence, leaving continuous professional monitoring may also generate uncertainty.
Amonoo et al5 noted continuing psychological challenges during early post-transplantation, especially with complications, prolonged recovery, or readmission. Parisek et al12 identified burdens related to self-management, graft-versus-host disease (GVHD), infection prevention, and restricted social participation among allogeneic HSCT survivors. Lee and Halliday2 also reported that psychological effects associated with protective isolation may persist after discharge. Relief may therefore coexist with concerns about relapse, infection, GVHD, complications, and readmission.
Heterogeneity across patient populations
Emotional trajectories differ across populations. Zhou et al13 studied 148 pediatric HSCT patients and reported PTSD incidences of 12.8% before transplantation, 69.6% at 2–3 weeks, and 10.1% at 3 months. Age was associated with PTSD before transplantation and at 3 months, while the caregiver-child relationship was associated with PTSD at 2–3 weeks.
Qin et al6 identified associations between anxiety or depression and age, gender, marital status, household income, and religious beliefs. Transplantation type, complications, symptom burden, isolation, and social support may also contribute to heterogeneity3,5. Accordingly, phase-related patterns can inform clinical observation but should not replace individualized assessment.
Assessment of emotional states in HSCT patients
Psychological assessment should extend beyond a single pre-transplant evaluation. Wiener et al14 found that 96% of surveyed HSCT programs routinely performed pre-transplant psychosocial assessment, whereas only 27% routinely conducted follow-up assessments.
Validated patient-reported instruments can complement interviews and clinical observation. Instrument selection should reflect the psychological domain, physical condition, and purpose of assessment. Representative HSCT assessment instruments15,16,17,18 are summarized in Table 1. These tools are intended for screening or symptom assessment and do not replace formal psychiatric diagnosis when clinically significant disorders are suspected.
Factors associated with psychological distress in HSCT patients in laminar airflow wards
Psychological distress during HSCT reflects the interaction of environmental, physical, biological, informational, and social factors whose relative importance may change with treatment phase and individual circumstances.
Environmental isolation factors
Protective isolation restricts contact with family, friends, and usual social networks and disrupts normal activities, potentially contributing to loneliness, anxiety, and loss of control2. In 168 HSCT patients in laminar airflow wards, Wen et al19 found psychological distress associated with sleep disturbance, post-transplant physical symptoms, duration of isolation, absence of family accompaniment, and sociodemographic and financial factors. Thus, isolation should be considered together with physical and social circumstances.
Physical symptom factors
Conditioning and transplantation-related complications can cause nausea, vomiting, mucositis, fatigue, pain, appetite loss, sleep disturbance, and functional impairment. Persistent symptoms may increase concerns about treatment and recovery. Martynowicz et al3 emphasized interactions between physical and mental health and noted that severe symptoms may limit participation in psychological interventions. Symptom and emotional assessment should therefore be complementary components of supportive care.
Biological mechanism factors
Transplantation-related biological processes may contribute to psychological symptoms. Nakamura et al20 noted that corticosteroids and other transplant-related medications should be considered when assessing insomnia, mood changes, anxiety, depression, and delirium.
Nelson et al21 investigated inflammatory cytokines and depressive symptoms following autologous or allogeneic hematopoietic cell transplantation. Higher IL-6 and IL-10 concentrations were associated with more severe depressive symptoms, and within-person cytokine changes corresponded with changes in depression severity. These findings suggest a possible inflammatory contribution, although psychological distress remains multidimensional.
Information deficits and uncertainty
HSCT requires patients to process complex information about conditioning, procedures, infection prevention, complications, symptom management, self-care, and prognosis. Chen et al7 identified difficulty obtaining reliable information and managing diverse information sources among patients in laminar airflow rooms. Because needs change across transplantation stages, repeated, individualized, and understandable communication may be preferable to delivering large amounts of information at once.
Social and family support factors
Social support is associated with psychological well-being. Among 250 autologous and allogeneic HSCT recipients, Amonoo et al22 found that greater pre-transplant social well-being was associated with better quality of life and lower psychological distress and PTSD symptoms six months later.
Wen et al19 identified absence of family accompaniment as associated with psychological distress in laminar airflow wards. Caregivers may also experience substantial burden: Yang et al23 reported anxiety, depression, distress, uncertainty, caregiving burden, and unmet needs among informal caregivers before HSCT. These associations demonstrate the relevance of social support but do not establish the effectiveness of specific family-support interventions.
Based on this narrative synthesis, a conceptual framework was developed incorporating environmental isolation, physical symptoms, biological mechanisms, information deficits and uncertainty, and insufficient social and family support, with demographic and clinical characteristics as contextual modifiers (Figure 1). The framework represents associations identified in the reviewed literature rather than established causal pathways.
Role of nurses and nursing interventions for emotional well-being in laminar airflow wards
Nurses maintain contact with patients during HSCT and can identify emotional changes, provide information and support, reinforce symptom management and coping strategies, facilitate family communication, and refer patients for specialized psychological or psychiatric care. However, the supporting evidence differs among interventions: some have been directly evaluated clinically or in randomized trials, whereas others remain practice-oriented strategies supported by observational, qualitative, or review evidence.
Integration of symptom management and emotional care
Because physical and psychological symptoms interact, effective management of nausea, vomiting, fatigue, pain, and sleep disturbance may also support emotional adjustment.
Su et al17 evaluated a non-vomiting management model for patients in laminar airflow isolation units. The clinical application included 100 patients, with 50 each in the intervention and control groups. The intervention group had lower nausea and vomiting burden, better Functional Living Index-Emesis scores at several post-transplant time points, and lower anxiety and depression scores at selected transplantation and pre-discharge assessments. These findings provide preliminary empirical support for integrating symptom and emotional care, although multicenter confirmation is required.
Continuous psychological support, communication, and psychoeducation
Psychological support should respond to changing needs throughout the transplantation process. Before transplantation and during entry into isolation, nurses can explain the environment, treatment stages, expected symptoms, infection-prevention measures, and methods of obtaining assistance. Information should be manageable, individualized, and reinforced as needed.
Nakano et al24 evaluated a pre-transplant nursing intervention that combined informational support, confirmation of understanding, and emotional support in 18 patients undergoing allogeneic HSCT. Illness-related uncertainty decreased significantly, although anxiety and depression did not. Cioce et al25 reported that therapeutic patient education improved knowledge of transplantation-related risks and complications and contributed to the management of psychological distress.
During isolation, brief regular communication can identify concerns and allow patients to express fear, uncertainty, or frustration. Persistent or severe psychological symptoms should prompt referral for specialized care. Support should also be phase-specific: anxiety and uncertainty may require greater attention at entry into isolation, symptom burden and low mood during myelosuppression, and self-management and independence during recovery and discharge.
Integration of palliative care
Palliative care represents an intervention supported by randomized evidence. El-Jawahri et al26 conducted a multisite randomized trial in autologous and allogeneic HSCT patients. The intervention involved twice-weekly inpatient palliative-care visits during transplantation hospitalization. Compared with usual care, it was associated with better quality of life and improvements in psychological outcomes, including lower depressive and post-traumatic stress symptoms at relevant follow-up assessments. Implementation, however, depends on specialist availability and institutional resources.
Family and social support
Reduced family contact and lower social support are associated with psychological distress19,22, while caregivers may themselves experience distress and unmet needs23. Where infection-control requirements permit, nurses can facilitate telephone or video contact with family and friends and provide families with guidance about supportive communication and emotional responses.
Because direct evidence for specific family-support interventions remains limited, these approaches should be regarded as individualized supportive strategies rather than interventions with firmly established psychological efficacy.
Daily routine, sleep, relaxation, and digital or recreational support
A structured daily routine incorporating treatment, rest, light activity, social communication, and meaningful leisure may help preserve a sense of normality during isolation. Sleep also warrants attention because sleep disturbance has been associated with psychological distress in HSCT patients in laminar airflow wards19.
Xia et al27 evaluated relaxation training combined with a music-based intervention in 62 HSCT patients. Depression decreased significantly compared with conventional care, whereas anxiety did not significantly improve. The small quasi-experimental design means these findings should be considered promising rather than definitive.
Amonoo et al28 evaluated a six-module virtual-reality psychosocial intervention incorporating psychoeducation, coping skills, acceptance strategies, and supportive content. The pilot randomized trial demonstrated feasibility and preliminary potential benefits for quality of life and psychological outcomes, but larger confirmatory trials are needed.
Dantanus Hickey et al29 reviewed 16 studies of art- and music-based interventions during stem cell transplantation. Reported benefits included creative expression, recreation and distraction, relationship building, social connection, and a sense of normality, although study quality and treatment effects varied. Drawing, painting, music, reading, and patient-preferred crafts may therefore be offered as low-burden supportive activities without implying uniformly established efficacy.
The principal nursing and supportive interventions and the strength of their evidence are summarized in Table 2.
Current status and challenges of intervention research
The intervention literature remains heterogeneous. Inpatient palliative care has randomized clinical evidence, whereas other approaches rely on smaller clinical studies, feasibility trials, observational associations, or reviews. Differences in transplantation type, populations, intervention content, outcome measures, and follow-up further restrict comparison.
Physical symptoms, fatigue, mucositis, and prolonged isolation may reduce patients' ability to participate in psychological interventions3. Financial burden is another concern. Schaefer et al30 found in a prospective longitudinal analysis of allogeneic HSCT recipients that greater financial toxicity was associated with greater anxiety, depression, and post-traumatic stress symptoms and poorer quality of life.
Current evidence therefore does not support one psychological nursing protocol for all HSCT patients. Future studies should use adequately powered prospective or randomized designs where feasible, clearly report transplantation characteristics, employ standardized psychological outcomes, and distinguish established intervention effects from promising but insufficiently tested supportive strategies.
Limitations of existing research and future directions
Several limitations characterize the current evidence. First, many investigations are single-center studies with relatively small samples, while patient characteristics, transplantation types, assessment instruments, and evaluation time points differ substantially. These differences limit direct comparison and prevent establishment of a uniform emotional trajectory3,6,13.
Second, biological mechanisms remain incompletely understood. Transplant-related medications and inflammatory activity may contribute to emotional symptoms20,21, but interactions among biological changes, physical symptoms, isolation, and psychosocial stress require further investigation. Studies integrating psychological assessments with biological indicators may clarify these relationships.
Third, intervention research remains methodologically heterogeneous. Palliative care, relaxation-based approaches, education, and digital psychosocial support have shown encouraging findings24,25,26,27,28,29, but variation in interventions, samples, study designs, and outcomes limits generalizability. Adequately powered, multicenter, prospective, and randomized studies are needed to identify effective approaches and appropriate treatment stages.
Family-centered care also warrants further study. Social support is associated with patient psychological outcomes22, whereas caregivers may experience distress, uncertainty, and unmet needs23. Research should determine whether structured family education, communication support, or caregiver-focused interventions improve outcomes for patients and caregivers.
Patient heterogeneity is equally important. Emotional responses may differ by age, transplantation type, complications, symptom burden, socioeconomic circumstances, and social support6,13,19,30. Future studies should therefore investigate phase- and subgroup-specific needs rather than assume that a single intervention is appropriate for all patients.
Finally, psychological assessment requires greater standardization. Repeated, validated assessments at clearly defined peri-transplant time points may improve the characterization of emotional changes and the identification of patients requiring additional support14,15,16,17,18. Combining quantitative measures with qualitative approaches may further clarify changing experiences and needs. Future research should therefore prioritize longitudinal and multicenter designs, clarification of biological and psychosocial mechanisms, standardized assessment, family-centered care, and rigorous evaluation of individualized, stage-specific interventions.
