Bridge study protocol: an international, observational cohort study on the transition of healthcare for adolescents with chronic conditions

Anxiety and care experiences in adolescents with chronic health conditions: an international, longitudinal study across the transfer of care

OBJECTIVES

To evaluate changes in anxiety, care experiences and condition impact among adolescents with chronic health conditions in two countries as they transfer to adult healthcare and to assess factors influencing anxiety levels.

DESIGN

A longitudinal international study. Data was collected by questionnaires before (2017-2021) and a year after (2018-2022) transfer of care.

SETTING

Two specialist hospitals in Finland and Australia.

PARTICIPANTS

440 adolescents with chronic health conditions were recruited from Finland (FIN n=237; mean age 17.2) and Australia (AUS n=203; mean age 18.3) with the answering percentage FIN 68.8% and AUS 55.2% of the first time point.

MAIN OUTCOME MEASURES

The validated State-Trait Anxiety Inventory short form (STAI) was used to measure care-related anxiety. Care experiences were measured using eight questions from the Adolescent-Friendly Hospital Survey. Self-reported condition impact was measured by a Visual Analogue Scale. Care experiences, condition impact, country and age were included in regression analyses as predictors of care-related anxiety.

RESULTS

At baseline, there were few clinically meaningful differences between participants at the two sites. Adolescents reported positive care experiences both before and after the transfer of care. In regression analyses after the transfer of care, adolescents with lower condition impact experienced lower anxiety levels than adolescents with higher condition impact (beta -9.00, 95% CI -13.85 to 4.16, p<0.001). After the transfer of care, adolescents who reported negative care experiences also reported higher anxiety (median STAI score 40.0 (IQR 30.0-50.0) versus 33.3 (IQR 23.3-41.6), p<0.001).

CONCLUSION

Across two different healthcare systems, most adolescents with chronic health conditions reported low anxiety and positive care experiences before and after transfer to adult healthcare. Beyond efforts to generally enhance positive care experiences, focusing on adolescents with higher-impact chronic conditions may reduce disease-related anxiety.

Changes in health-related quality of life during transition to adult healthcare: an international prospective cohort study

OBJECTIVE

To study changes in health-related quality of life (HRQoL) in adolescents and young adults (AYAs) with chronic medical conditions across the transfer to adult healthcare and associations of HRQoL with transition readiness and experience of care.

METHODS

Participants in this international (Finland, Australia) prospective cohort study were recruited in the year prior to transfer to adult health services and studied 12 months later. In addition to two HRQoL scales (Pediatric Quality of Life inventory (PedsQL), 16D), the Am I ON TRAC for Adult Care Questionnaire and Adolescent Friendly Hospital Survey measured transition readiness and experience of care and categorised by quartile. Data were compared before and after transfer to adult healthcare.

RESULTS

In total, 512 AYAs completed the first survey (0-12 months before transfer of care) and 336 AYAs completed it 1 year later (retention rate 66%, mean ages 17.8 and 18.9 years, respectively). Mean total PedsQL scores (76.5 vs 78.3) showed no significant change, although the social and educational subdomains improved after transfer of care. The mean single-index 16D score remained the same, but in Finland, distress increased and the ability to interact with friends decreased after transfer. AYAs within the best quartiles of experience of care and transition readiness had better HRQoL than AYAs within the worst quartiles.

CONCLUSIONS

Overall HRQoL of AYAs remained unchanged across the transfer to adult healthcare. Recognising and supporting AYAs with unsatisfactory experience of care and poor transition readiness could improve overall HRQoL during the transition process.

Health-related quality of life and self-reported health status in adolescents with chronic health conditions before transfer of care to adult health care: an international cohort study

BACKGROUND

Heath-related quality of life (HRQoL) is lower in adolescents with chronic health conditions compared to healthy peers. While there is evidence of some differences according to the underlying condition and gender, differences by measure and country are poorly understood. In this study we focus on the differences in HRQoL in adolescents with various chronic medical conditions in the year before transfer of care to adult health services. We also study the associations of two different HRQoL measurements to each other and to self-reported health.

METHODS

We recruited 538 adolescents from New Children`s Hospital, Helsinki, Finland, and the Royal Children`s Hospital, Melbourne, Australia in 2017-2020. We used two validated HRQoL measurement instruments, Pediatric Quality of Life Inventory (PedsQL) and 16D, and a visual analog scale (VAS) for self-reported health status.

RESULTS

In total, 512 adolescents (50.4% female, mean age 17.8 [SD 1.2] years), completed the survey measures. Higher HRQoL was reported in males than females in both countries (PedsQL 79.4 vs. 74.1; 16D 0.888 vs. 0.846), and in adolescents from Finland than Australia (80.6 vs. 72.2 and 0.905 vs. 0.825, p < 0.001 for all). Adolescents with diabetes, rheumatological, nephrological conditions and/or organ transplants had higher HRQoL than adolescents with neurological conditions or other disease syndromes (p < 0.001). PedsQL and 16D scores showed a strong correlation to each other (Spearman correlation coefficient r = 0.81). Using the 7-point VAS (1-7), 52% (248 of 479) considered their health status to be good (6-7) and 10% (48 of 479) rated it poor (1-2). Better self-reported health was associated with higher HRQoL.

CONCLUSIONS

The HRQoL of transition aged adolescents varies between genders, diagnostic groups, and countries of residence. The association between self-reported health and HRQoL suggests that brief assessment using the VAS could identify adolescents who may benefit from in-depth HRQoL evaluation.

Transition readiness among finnish adolescents with juvenile idiopathic arthritis

BACKGROUND

With chronic diseases, the responsibility for care transfers to adult clinics at some point. Juvenile idiopathic arthritis (JIA) is the most common persistent rheumatic condition in children. A successful transition requires sufficient self-management skills to manage one´s chronic condition and all the tasks involved. In this study, we evaluated transition readiness in Finnish patients with JIA. We aimed to find practical tools to support a successful transition and to study the possible consequences of an unsuccessful transition.

METHODS

The usefulness of a specific questionnaire, which was administered to 83 JIA patients, was evaluated in this study. We also gathered information from their first adult clinic visit to assess the success of their transition and its relation to disease activity.

RESULTS

In 55 (71%) patients, the transition was estimated to be successful. We were able to determine a cut-off score in the questionnaire for a successful transition: the best estimate for a successful transition is when the score is 24 or more. At the first adult clinic visit, an unsuccessful transition was evident in its effect on disease outcome. If the transition was defined as successful, the DAS28 was better.

CONCLUSION

We found the questionnaire to be a useful tool for evaluating transition readiness. Determination of a successful transition helped us identify those adolescents who needed more profound support to improve their self-management skills and thus enhance their transition process. An unsuccessful transition was shown to negatively impact on disease outcomes.

Disease control and psychiatric comorbidity among adolescents with chronic medical conditions: a single-centre retrospective study

BACKGROUND

To investigate disease control, psychiatric comorbidity, substance use and their possible associations in adolescents with chronic medical conditions before transfer to adult healthcare.

METHODS

We collected clinical data from the year preceding transfer of care and psychiatric data from the records of the paediatric hospital in Helsinki, Finland (population base 1.7 million). Participants were grouped into three disease and/or adherence control categories (good, some evidence of concern, poor) based on clinical data from the medical records of the year preceding the transfer of care. Participants completed the Adolescent's Substance Use Measurement Questionnaire before transfer of care and were divided into four risk subgroups accordingly.

RESULTS

In total, 253 adolescents (mean age 17.3 years, SD 1.2) from six paediatric subspecialties participated in this study. Disease control and/or adherence were rated as good in 28% (n=70), moderate in 42% (n=105) and poor in 30% (n=76) in the year before participants transferred to adult health services. A quarter of participants had at least one psychiatric diagnosis during adolescence. Adolescents with concomitant psychiatric diagnoses more often had poor disease control of their chronic medical condition than adolescents with only a medical condition (44% vs 26%; n=25 of 59 vs 51 of 194, respectively). More than half of adolescents (56%) were abstinent or used substances infrequently; 10% (n=26) reported hazardous substance use.

CONCLUSIONS

Psychiatric comorbidity in adolescents with chronic medical conditions is common. Its negative association with disease control and possible substance use should be considered in the transition process to adult health services.
