1. Introduction
Epidemiology for Adolescent Scoliosis
Scoliosis is defined as an abnormal vertebral rotation or curvature forming conditions including lateral curvature
and vertebral rotation. The curve is usually "S"- or "C"-shaped over three dimensions. Idiopathic scoliosis is
most commonly found in adolescents of 10 to 17 years of age, being known as adolescent idiopathic scoliosis
(AIS). In 80% of cases with idiopathic scoliosis the cause is largely unknown. Those possible causes include
hormone causes, asymmetric growth, muscular imbalance and genetic factors (Menger & Sin, 2021). Several
common appearance characters are found in patients with AIS, including: 1. Uneven height of bilateral shoulders.
2. One shoulder blade is more prominent than the other. 3. Uneven length of bilateral arms. 4. Asymmetric
waistline, with uneven height of bilateral hips. 5. More prominent ribs (Burton, 2013; Mesiti, 2021).
In the US (Thomas et al., 2021), the age- and sex-standardized total annual incidence rate of AIS reaches
522.5/100,000 person-year [95% confidence interval (CI): 498.2, 546.8], with female incidence rate doubles that
in males (p < 0.05). The incidence rate for newly diagnosed cases with a Cobb angle of > 10° in X-ray shows
181.7/100,000 person-year (95% CI: 167.5, 196.0). In studies (Dunn et al., 2018; Grossman et al., 2018), it is
found that the prevalence rate for a Cobb angle of 10° among idiopathic scoliosis patients aged 10 to 16 years
http://ijsn.julypress.com International Journal of Studies in Nursing Vol. 9, No. 3; 2024
2
is 1% to 3%, ranging from 0.15% to 0.66% in boys and from 0.24% to 3.10% in girls, indicating higher
prevalence in females than in males. Cumulative incidence estimates are 1.0% for a Cobb angle 20° and 0.4%
for a Cobb angle 40°. In the study conducted by Bondar et al. (Bondar, Nguyen, Vatani, & Kessler, 2021) for
the adolescent group in Southern California, the incidence rate was 28.6/100,000, with females had a
significantly greater initial curve magnitude than boys (18.1° vs. 16.7°). In China (Qiu, 2017), the incidence rate
of scoliosis varied from 0.6% to 2.0%, with idiopathic scoliosis sharing roughly 90%.
Care Journey Map for Patients with Adolescent Idiopathic Scoliosis
Treatment for patients with AIS may involve interventions such as brace, plaster cast, traction and surgery.
Aspects of care include physiological, spiritual and social facets. Patient’s healthcare journey consists of
outpatient clinic visit, hospitalization and returning home. During seeking medical attention, maintaining the
consistency and completeness of care contents from clinical nursing personnel to ensure the care contents patient
received is a very important issue.
The expert consensus for surgical treatment of AIS collected by Arima (Arima et al., 2021) in Japan has shown a
roughly 70% of consistency in aspect of postoperative nursing, indicating the variations for AIS management
among institutions. Nevertheless, using a unified care tool for identifying variations to develop consensus can
enhance care consistency. Ly et al. (Ly, Runacres, & Poon, 2021) suggest that journey map longitudinally
describes patient’s healthcare process in various settings and time periods. The identified consistent and overall
structure enables medical personnel to better understand the disease course patient experienced, facilitating the
interaction between patient and healthcare service to identify the model for illness progression, further realizing
patient’s care needs and experience, which helps nursing providers positively and properly solve these problems.
Benson (Benson et al., 2022) developed a cervical dystonia patient journey map (CDPJM) that describes
patient’s experience from diagnosis through to treatment. It compares medical interventions with the contents
that patients want and need, enabling healthcare providers to improve their services, providing services that meet
patient’s requirement. Flood et al. (Flood et al., 2021) indicate that a journey map presents patient’s complete and
specific experience from both practical and emotional aspects, which can be used in creating service models,
facilitating to enhance the development of new intervention measures for healthcare service, meeting the needs
of patients and healthcare professionals. Sundar (Sundar et al., 2022) analyzed the effects on patient care by
providing standardized nursing pathway in AIS patients receiving treatment of posterior spinal fusion and found
the improved patient mobility (before: 16.7%, after: 53.3%, P < 0.00001), a shortened hospital stay (before: 4.14
days, after: 3.36 days, P = 0.00006), reduced postoperative infection (before: 5.1%, after: 0.48%, P = 0.00547),
reduced readmission (before: 6.0%, after: 0.48%, P = 0.0021) and reduced re-surgery (before: 5.1%, after: 0.96%,
P = 0.0195), indicating that nursing care journey enables healthcare personnel to provide comprehensive care,
achieving the benefit in enhancing the quality of patient care.
Measures of treatment and care
Patients with different Cobb angles undergo different treatment measures, those with a Cobb angle of 10°to
25°receive X-ray follow-ups at 3, 6, or 12 month intervals; patients with a Cobb angle greater than 25°but less
than 40°- 45°or with a curve increase of 5 degrees or more during follow-up period are recommended to wear
the brace, undergoing a surgery is primarily required for those who are with more than 40°- 45°, in which spinal
fusion is the most common surgery (Dunn et al., 2018; Menger & Sin, 2021).
2. Aim of the Study
This article aims to create the Care Journey Map for Scoliosis Patients to provide standardized care contents,
investigating
(1) The reliability and validity of the “Care Journey Map for Scoliosis Patients”
(2) The completeness rate for clinical use of the “Care Journey Map for Scoliosis Patients” among nursing
personnel
(3) The quality of patient care after use of the “Care Journey Map for Scoliosis Patients”
(4) The degree of agreement in clinical use of the “Care Journey Map for Scoliosis Patients” among nursing
personnel
Operation Definitions
AIS: AIS patients aged 10 to 17 years old with a Cobb angle of greater than 10˚ may undergo hospitalization
treatment or spinal surgery treatment.
The completeness rate for clinical use of the “Care Journey Map for Scoliosis Patients” among nursing personnel:
http://ijsn.julypress.com International Journal of Studies in Nursing Vol. 9, No. 3; 2024
3
With the measure of medical chart review by 2 senior orthopedic nursing experts, the consistency of
implementation for care items that clinical nurses are required to conduct is checked. The formula for the
completeness rate: The item number nursing personnel implemented/the item number required to be
implemented specified by experts x 100%.
3. Methods and Subject
3.1 Research Design
Cross-sectional study.
3.2 Setting
Venues for data collection include 4 orthopedic wards at a medical center in northern Taiwan.
3.3 Participants
The enrollment period was between September 1 and December 31, 2021, including patients diagnosed as AIS
requiring hospitalization treatment or a surgery.
3.4 Methods and Phase of Data Collection
3.4.1 Study Tools
(1) In the “Care Journey Map for Scoliosis Patients”, care contents for patients in the period before
hospitalization to discharge returning home were created by the senior head nurse with 30-years clinical
experience based on relevant AIS literature. The continuous care contents were completed according to the
process involving illness treatment and care. It was organized based on the 3 major fundamentals including
outpatient clinic visit, hospitalization and returning home with a total of 71 items of care contents. The
measure contents provided include 5 items for outpatient clinic visit (1 week before surgery), 12 items for
examination (1 day prior to surgery), 14 items for treatment (the day undergoing surgery), 19 items for the
postoperative care during the first 3 days after surgery, 11 items for the postoperative care during the 7 to 14
days after surgery, and 10 items for returning home (discharge preparation and home health care).
(2) Measuring the degree of agreement among nursing personnel: The contents of self-completed structured
questionnaire include 2 parts, with the first part involving basic information such as job tenure, orthopedic
seniority, and nursing clinical ladder. The second part consists of 7 questions involving the clarity,
completeness, significance, feasibility, willingness, capability and overall satisfaction. The 5-point Likert
scale was used, scoring from 5 points for “strongly agree” to 1 point for “strongly disagree”.
(3) The consistency in use among nursing personnel: The contents and instructions of this tool were introduced
through ward morning meetings by the head nurse who organized and developed the tool. Moreover,
discussions were conducted to ensure nursing staff understand the procedure and methods in implementation.
3.4.2 Administrative Approach
During the interrogation in outpatient clinic, the orthopedists confirmed the patients who were qualified for
enrollment. Nursing personnel then provided scoliosis patients with care contents according to the “Care Journey
Map for Scoliosis Patients”.
3.4.3 Statistics and Data Analysis
The Excel software was used to calculate the expert validity (content validity index, CVI) in percentage,
completeness in use among nursing personnel, the degree of agreement in use among nursing personnel
presented in frequency and percentage.
3.4.4 Ethical Considerations
The study complies with research ethics and acquired approval from the institutional review board (IRB, No.
2019-02-006AC). The study commenced with information that was purposed to be impaired by the completion
of the study.
4. Results
4.1 Expert Validity for the “Care Journey Map for Scoliosis Patients”
The contents of the “Care Journey Map for Scoliosis Patients” were reviewed based on the opinions from 7
experts, with 5 females (71.4%) among them. In the fields of experts, there were 1 orthopedic specialist, 1
pediatric occupational therapist, 1 orthopedic nurse specialist, 1 assistant professor for the fields of internal
medicine and surgery in school, 1 nursing director from long-term care institution, 1 orthopedic head nurse and 1

senior nurse from orthopedic ward. Their job tenure varies from 15 to 35 years, with the orthopedic seniority
from 10 to 30 years. For the academic background, masters degree achieves 57.1%, and 28.6% with doctorate
degrees. The “clarity”, “correlation” and “significance” for each item of the contents were scored by these 7
experts, using a 4-point Likert scale in which 1 point indicates very insignificant, inappropriate and unclear that
become unnecessary to be included. Two points indicates insignificant, inappropriate and unclear that requires a
major reversion. Three points indicates significant, appropriate and clear that requires a minor reversion. Four
points indicates very significant, appropriate and clear that requires to be included. After compiling statistics, the
overall expert validity was 0.98, with 0.97 for “clarity”, 0.99 for “correlation”, and 0.99 for “significance”,
indicating a good validity. Nevertheless, there were 11 items regarded as with insufficient clarity by experts
which required more clear description, respectively including: “Evaluation – 1 week prior to surgery: arranging
preparation for surgical treatment”, “Treatment – The day undergoing surgery – arriving operation room for
confirmation while undergoing surgery”, “Care – within the first 3 days after surgery – physiologically-
continuous rehabilitation exercises – upper and lower limbs exercise (augmented reality, AR) training”, “Care –
within the first 3 days after surgery – psychologically – correcting the body image disturbance”, “Care – within
the first 3 days after surgery – psychologically – increasing the cognition for surgical prognosis”, “Care – within
the first 3 days after surgery – psychologically – reducing peer isolation (introducing patient groups)”, “Care –
within the 4-7 days to the 14 days after surgery – continuing relevant care – brace”, “Care – within the 4-7 days
to the 14 days after surgery– continuing relevant care – wearing the brace for 1 to 3 months”, “OPD follow-up –
discharge preparation and transportation service – phone calling follow-up”, “OPD follow-up – applying a pad
using bath towels after returning home – for protection of the back and neck”, and “Health promotion/home
health care – allowing shopping or visiting, playing games”.
4.2 Completeness of Care Map Project Selection
Two clinical experts jointly reviewed 22 care maps to check whether the care content of the patient checked by
the nursing staff was complete. If the checked items were completely consistent with the patient's needs, it was
defined as completeness 100%."Scoliosis Patient Care Journey Map" has 71 care items, of which 54 care items
are completely checked by the nursing staff (completeness rate 100%), but 6 of them are often left unchecked,
namely "Checkup" - 1 day before surgery - Introduction to postoperative pipeline images (complete rate 36.4%)",
"Examination - 1 day before surgery - Introduction to comprehensive care guidance smart link map link
(complete rate 36.4%)", "1 day before surgery Care: Rehabilitation exercises - Breathing trainer exercises -
Cardiopulmonary movements, upper and lower limb movements (with AR training) (Complete rate 45.4%)",
"Treatment - Day of surgery - Infection prevention: Continuous rehabilitation exercises - Breathing trainer
exercises - Cardiopulmonary exercises (with AR training) (complete rate 45.4%)", "Care-within 3 days after
surgery-continuous rehabilitation exercises-respiratory trainer exercises-cardiopulmonary exercises (with AR
training) (complete rate 45.4%)", "Care - 4-7~14 days after surgery: Continuous rehabilitation exercises - upper
and lower limb movements (AR training) (complete rate 45.4%)". It shows that rehabilitation exercises are often
ignored in the care content.
4.3 The Quality of Patient Care
The analysis for care quality indicators in 22 patients using the “Care Journey Map for Scoliosis Patients”
showed the incidence of nerve injury was 0%, incidence of wound infection was 0%, incidence of fall was 0%,
incidence of complications was 0%, the rate for 60-day readmission was 0%, incidence of pressure injury was
0.36%, and hospital stay of 3-29 days, with an average hospital stay of 11 days, indicating good care quality.
4.4 The Degree of Agreement in Clinical Use of the “Care Journey Map for Scoliosis Patients” Among Nursing
Personnel
In the survey on the degree of agreement in clinical use of the “Care Journey Map for Scoliosis Patients” among
18 nursing personnel, 3 to 10 years of job tenure and orthopedic seniority was in the majority, sharing 44.4%. For
nursing clinical ladder, both N3 and N4 achieved 44.4% (Table 1). The range of the degree above agreement was
55.6%-100%, with 2 items achieved 100% for the degree above agreement, which respectively were “You
consider this care map is complete”, “You consider this care map is significant”. There were 3 items achieved
89.9% for the degree above agreement, including “You consider this care map feasible”, “You like to use this care
map”, and “You are satisfied with using this care map”. The item with a relatively lower degree above agreement
was “You consider this care map clear”, sharing 55.6% (Table 2).

4.5 Result for the Reversion of Care Journey Map
The “Care Journey Map for Scoliosis Patients” was revised based on the opinions from nursing expert review
and suggestion from nursing staff, providing more detailed description about wording according to expert
opinions: (1) Revised “OPD-Evaluation-One week before surgery-Integrated OPD guidance-Occupational
therapist” by adding physical therapist, thus the reversion was “OPD-Evaluation-One week before
surgery-Integrated OPD guidance-Occupational/Physical therapist”. (2) “1 day prior to surgery – briefing on
smart link and map link of holistic nursing guidance” was deleted due to the unclear content. (3) “One day prior
to surgery – examination item - monitoring spinal cord function” was added. (4) “Bone Health” was added,
“Within the first three days after surgery – Nutritional care fish, meat, protein, vitamin C” was revised as
“Within the first three days after surgery – Nutritional care – fish, meat, protein, vitamin C, and Bone Health”. (5)
Reversion for descriptive content, “Continuous rehabilitation exercise – upper and lower limbs exercise (AR
training)” was revised as “Continuous rehabilitation exercise – upper and lower limbs exercise”. (6) “Returning
home – Discharge preparation/Rehabilitation – Wound care – Freshening up (hair and body). (7) The 71 items of
care content were revised as 72 items, the measure contents provided including 5 items for OPD visit (1 week
prior to surgery), 11 items for examination (1 day prior to surgery), 15 items for treatment (the day undergoing
surgery), 19 items for care within the first 3 days after surgery, 11 items for care within the 7 to 14 days after
surgery, and 11 items for returning home (discharge preparation and home health care) (originally 10 items).

indicate the benefits of journey map to enhance care capability for nursing personnel.
6. Limitation of the Study
The “Care Journey Map for Scoliosis Patients” provides nursing personnel with a basis for care contents. At this
time, the study investigates only for the development of contents. In the future, the comparison can be conducted
on patients’ prognosis quality and care satisfaction after receiving such a care criterion, ensuring the benefits in
clinical application.
7. Conclusion
Past studies on care journey mapping for adolescents with idiopathic scoliosis have the following shortcomings:
(1) Insufficient Assessment of Patient Needs: Many studies focus on clinical treatment outcomes but fail to
systematically evaluate the psychological and emotional needs of patients throughout the treatment process.
(2)Lack of Multilevel Participant Perspectives: Most studies primarily rely on the viewpoint of the medical team
or the patient alone, lacking input from a variety of stakeholders such as family members, caregivers, and
other related healthcare professionals, which limits the comprehensiveness of the care journey map.
(3) Absence of a Dynamic Adjustment Mechanism: Existing care journey maps are often static, failing to
accommodate the evolving needs of patients as the disease progresses or as their mental state changes. This
limits the ability to optimize the timing and approach of care interventions.
Advantages of This Study Based on Previous Insufficiencies:
(1)Comprehensive, Patient-Centered Needs Assessment: In designing the care journey map, we conducted an
in-depth assessment of patient needs, integrating psychological, social, and emotional dimensions to enhance
the overall care experience.
(2) Inclusion of Multiple Stakeholder Perspectives: This study engaged participants from various levels,
including the medical team, patients, family members, and caregivers, to gather diverse perspectives and
design a care process that better aligns with real-world needs.
(3)Dynamic Adjustment and Personalization: We developed a dynamic care journey map that allows for timely
adjustments based on individual patient needs and changes throughout the treatment process, ensuring the
most suitable and effective care interventions.
The “Care Journey Map for Scoliosis Patients” is a care criterion developed based on literature review by
nursing experts with years of clinical experience, considering transverse and longitudinal time axes as main parts
for the overall process in patient care. The map content was further reviewed by experts, with further reversion
based on the suggestion provided by nursing personnel after actually used in clinical patients. This tool is proved
to possess reliability and validity, can be a care criterion provided for clinical nurses’ compliance, meriting
clinical promotion.
8. Recommendation
(1) Expert validity for the “Care Journey Map for Scoliosis Patients” is 0.98, indicating great validity, which
can be used by clinical nursing personnel.
(2) The items 100% completely used in the “Care Journey Map for Scoliosis Patients” achieve 54 items, sharing
76.2%. The contents explanation is required to be strengthened, enhancing the implementation consensus
among nursing personnel to increase completeness rate.
(3) The overall satisfaction among nursing personnel for the “Care Journey Map for Scoliosis Patients” achieves
89.9%, moreover, 100% agree that the care map is complete and significant. This tool can be provided as a
care criterion for nursing personnel to comply with.

Background Patient journey maps are increasingly used as a tool that enables healthcare providers to refine their service provision to best meet patient needs. We developed a cervical dystonia patient journey map (CDPJM) that describes the holistic patient experience from pre-diagnosis through to long-term treatment. Methods The CDPJM was developed in 2 stages; a patient survey (open questions and multichoice) of 15 patients with CD was conducted to inform the design of the CDPJM, which was then refined and validated by an expert-patient focus group. Results Qualitative analysis of the patient survey supported five key stages of the patient journey: symptom onset, diagnosis and therapeutic relationship with healthcare professionals, initiation of care for CD, start of CD treatment, and living with treated CD. Following symptom onset, survey respondents described having multiple visits to their family doctor who prescribed strong pain killers and muscle relaxants and referred their patient to up to 10 different specialists for diagnosis. Over half (53.3%) of respondents had received ≥ 1 misdiagnosis. Respondents reported relief at having a diagnosis but a lack of understanding of the prognosis and treatment options; 46.7% said their neurologist did not spend enough time addressing their concerns. Survey respondents reported using a variety of alternative sources of information, including the internet (86.7%), self-help groups (66.7%) and information leaflets provided by health care professionals (60.0%). While botulinum toxin (BoNT) was consistently discussed as the main treatment option, some neurologists also mentioned physiotherapy, counselling, and other complementary approaches. However, patients were often left to seek complementary services themselves. Patients reported a ‘rollercoaster’ of relief with BoNT treatment with symptoms (and subsequent impact on daily life) returning towards the end of an injection cycle. “When BoNT works well I can return to an almost normal life … when the injections stop working so well, I have to rest more and avoid going to work and experience life restrictions.” Conclusions We present the first patient journey map for CD that can be used to guide local service mapping and to compare current provision with what patients say they want and need.

Background Journey mapping involves the creation of visual narrative timelines depicting the multidimensional relationship between a consumer and a service. The use of journey maps in medical research is a novel and innovative approach to understanding patient healthcare encounters. Objectives To determine possible applications of journey mapping in medical research and the clinical setting. Specialist palliative care services were selected as the model to evaluate this paradigm, as there are numerous evidence gaps and inconsistencies in the delivery of care that may be addressed using this tool. Methods A purposive convenience sample of specialist palliative care providers from the Supportive and Palliative Care unit of a major Australian tertiary health service were invited to evaluate journey maps illustrating the final year of life of inpatient palliative care patients. Sixteen maps were purposively selected from a sample of 104 consecutive patients. This study utilised a qualitative mixed-methods approach, incorporating a modified Delphi technique and thematic analysis in an online questionnaire. Results Our thematic and Delphi analyses were congruent, with consensus findings consistent with emerging themes. Journey maps provided a holistic patient-centred perspective of care that characterised healthcare interactions within a longitudinal trajectory. Through these journey maps, participants were able to identify barriers to effective palliative care and opportunities to improve care delivery by observing patterns of patient function and healthcare encounters over multiple settings. Conclusions This unique qualitative study noted many promising applications of the journey mapping suitable for extrapolation outside of the palliative care setting as a review and audit tool, or a mechanism for providing proactive patient-centred care. This is particularly significant as machine learning and big data is increasingly applied to healthcare.

Importance Adolescent idiopathic scoliosis, a lateral curvature of the spine of unknown cause with a Cobb angle of at least 10°, occurs in children and adolescents aged 10 to 18 years. Idiopathic scoliosis is the most common form and usually worsens during adolescence before skeletal maturity. Severe spinal curvature may be associated with adverse long-term health outcomes (eg, pulmonary disorders, disability, back pain, psychological effects, cosmetic issues, and reduced quality of life). Early identification and effective treatment of mild scoliosis could slow or stop curvature progression before skeletal maturity, thereby improving long-term outcomes in adulthood. Objective To update the 2004 US Preventive Services Task Force (USPSTF) recommendation on screening for idiopathic scoliosis in asymptomatic adolescents. Evidence Review The USPSTF reviewed the evidence on the benefits and harms of screening for and treatment of adolescent idiopathic scoliosis. Findings The USPSTF found no direct evidence on screening for adolescent idiopathic scoliosis and health outcomes and no evidence on the harms of screening. The USPSTF found inadequate evidence on treatment with exercise and surgery. It found adequate evidence that treatment with bracing may slow curvature progression in adolescents with mild or moderate curvature severity (Cobb angle <40° to 50°); however, evidence on the association between reduction in spinal curvature in adolescence and long-term health outcomes in adulthood is inadequate. The USPSTF found inadequate evidence on the harms of treatment. Therefore, the USPSTF concludes that the current evidence is insufficient and that the balance of benefits and harms of screening for adolescent idiopathic scoliosis cannot be determined. Conclusions and Recommendation The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of screening for adolescent idiopathic scoliosis in children and adolescents aged 10 to 18 years.

Study design: Retrospective review of patients ages 10-18 who underwent posterior fusion for adolescent idiopathic scoliosis (AIS) at a single institution from 2014 to 2019. Objective: The aim was to evaluate a standardized Care Path to determine its effects on perioperative outcomes in patients undergoing spinal fusion for AIS. Summary of background data: AIS is the most common pediatric spinal deformity and thousands of posterior fusions are performed annually. Surgery presents several postoperative challenges, such as pain control, delayed mobilization, and opioid-related morbidity. Optimizing perioperative care of AIS is a high priority to reduce morbidity and improving health care efficiency. Materials and methods: A total of 336 patients ages 10-18 were included in this study; 117 in the pre-Care Path cohort (2014-2015) and 219 in the post-Care Path cohort (2016-2019). Data compared included intraoperative details, length of stay, timing of mobilization, inpatient complications, emergency room (ER) visits, readmissions after discharge, postoperative complications, and reoperations. Results: The post-Care Path cohort had improved mobilization on postoperative day 0 (pre 16.7%, post 53.3%, P<0.00001), reduced length of stay (pre 4.14 days, post 3.36 days, P=0.00006), fewer total inpatient complications (pre 17.1%, post 8.1%, P=0.0469), and fewer instances of postoperative ileus (pre 8.5%, post 1.9%, P=0.0102). Within 60 days of surgery, the post-Care Path cohort had fewer ER visits (pre 12.8%, post 7.2%, P=0.0413), decreased postoperative infections (pre 5.1%, post 0.48%, P=0.00547), decreased readmissions (pre 6.0%, post 0.48%, P=0.0021), and decreased reoperations (pre 5.1%, post 0.96%, P=0.0195). There was a decrease in inpatient oral morphine equivalents in the Care Path cohort (pre 118.7, post 84.7, P=0.0003). Conclusions: Our Care Path for AIS patients demonstrated significant improvements in postoperative mobilization and decreases in length of stay, complications, infections, ER visits, readmissions, and reoperations.

Challenges faced by health systems have become increasingly complex, and expanding the range of methodological options available via interdisciplinary collaboration is important to enable researchers to address them. As complexity increases, it can be more difficult to ensure solutions remain patient-centered. Human-centered design is an approach that focuses on engaging with and understanding the needs of all services users while retaining a systems perspective. Therefore, design professionals skilled in these approaches are increasingly collaborating within health systems in pharmacy and health research teams. This methodological paper considers the potential contribution of human-centered design approaches to optimising development, implementation, and sustainability of patient-centered interventions in pharmacy and health services research. It provides an overview of human-centered design principles and their application, and outlines the emerging roles of design professionals in pharmacy and health services research. It focuses on three key human-centered design methods that can most readily be used by pharmacy and health services researchers. Journey mapping, prototyping, and user testing are discussed in detail. Journey mapping enables holistic visualisation of patient experience from practical and emotional perspectives. It may be used to visualize current practice or model potential future services, and can be informed by quantitative and qualitative data derived from both primary and secondary research. Prototyping facilitates exploration of interventions such as new services quickly and at low-cost. Health services researchers can utilize prototypes for services, processes, experiences, physical objects, environments, spaces, or digital tools for example. Formative evaluation and user testing supports rapid iteration of prototypes to ensure that they meet patient and healthcare professional needs. Finally, challenges with interdisciplinary collaboration and strategies to maximize the potential of using human-centered design approaches in pharmacy and health services research to address complex challenges, enhance practice and deliver benefits for service users, patients, and health systems are discussed.

Background: A successful disease screening strategy requires a high incidence of the condition, efficacy of early treatment, and efficient detection. There is limited population-based data describing trends in incidence of adolescent idiopathic scoliosis (AIS) in the United States and potential role of school screening programs on the incidence of AIS. Thus, we sought to evaluate the incidence of AIS over a 20-year period between 1994 and 2013 using a population-based cohort. Methods: The study population comprised 1782 adolescents (aged 10 to 18 y) with AIS first diagnosed between January 1, 1994 and December 31, 2013. The complete medical records and radiographs were reviewed to confirm diagnosis and coronal Cobb angles at first diagnosis. Age-specific and sex-specific incidence rates were calculated and adjusted to the 2010 United States population. Poisson regression analyses were performed to examine incidence trends by age, sex, and calendar period. Results: The overall age-adjusted and sex-adjusted annual incidence of AIS was 522.5 [95% confidence interval (CI): 498.2, 546.8] per 100,000 person-years. Incidence was about 2-fold higher in females than in males (732.3 vs. 338.8/100,000, P<0.05). The incidence of newly diagnosed AIS cases with radiographs showing a Cobb angle >10 degrees was 181.7 (95% CI: 167.5, 196.0) per 100,000 person-years. The overall incidence of AIS decreased significantly after discontinuation of school screening in 2004 (P<0.001). The incidence of bracing and surgery at initial diagnosis was 16.6 (95% CI: 12.3, 20.9) and 2.0 (95% CI: 0.5, 3.4) per 100,000 person-years, respectively. Conclusions: Overall population-based incidence of AIS decreased after school screening was discontinued. However, incidence of patients with a Cobb angle >10 degrees, initiation of bracing and surgery did not change significantly over time. This provides further data to help determine the role of scoliosis screening. Level of evidence: Level III.

Study design: Prognostic study, Level III. Objectives: The aim of this study was to determine the incidence and demographics of idiopathic scoliosis (IS) in a large cohort of children in a Southern California integrated healthcare system, and to identify the demographic or clinical factors associated with the greatest risk of IS. Summary of background data: Although many authors have reported on the incidence and prevalence of IS in children, there have been few incidence studies in the United States on large, self-contained populations. Methods: A retrospective chart analysis was done on diagnosed cases of IS within our integrated health care system in patients under age 18 years during the entire 2013 calendar year. Patient demographics were recorded and the incidence of IS was determined. Odds ratios (ORs) for having IS and for having more severe initial curve magnitudes based on demographics were determined using logistic regression models. Results: IS Incidence was 3.9, 28.6, and 393 per 100,000, respectively, for the infantile, juvenile, and adolescent group. The female incidence was more than twice that of males in all age groups. Multivariate logistic regression analysis showed Asians and non-Hispanic Whites had the highest OR of IS (OR 1.54 and 1.32 with 95% confidence interval [CI] 1.33-1.79 and 1.19-1.47). Whites, Blacks, and mixed-race patients had a significantly higher initial curve magnitude than Hispanics; females also had a significantly greater initial curve magnitude than boys (18.1° vs. 16.7°). Underweight patients had a 50% increased OR of IS versus normal weight (95% CI 1.16-1.94) with a progressively decreased OR of IS as weight increased. Conclusion: Our study of a large integrated healthcare system sheds light on the incidence of IS and the ORs based on weight, sex, and ethnicity/race. The overall incidence was lower overall than previously thought.Level of Evidence: 3.

Background: Surgical treatment for adolescent idiopathic scoliosis (AIS) has changed significantly with the advent of new medical devices and surgical procedures. Today, pre- and postoperative management differs widely between institutions. The purpose of this study is to establish consensus regarding the surgical management of AIS in Japan through the use of a questionnaire survey of experienced spine deformity surgeons. Methods: From February to March 2020, experienced spine deformity surgeons who perform more than 25 cases of AIS surgery annually were asked to respond to a questionnaire request regarding AIS surgical management formulated by the International Affairs Committee of the Japanese Scoliosis Society. For each of the questions, consensus was achieved upon a 70% agreement among respondents. Results: Responses were received from 25 of the 32 (78%) experienced spine deformity surgeons. The average age of the responding surgeons was 52 years with an average practice experience of 28 year. Consensus was achieved on 74 (76%) of the 97 aspects of care presented in the questionnaire and is broken down as follows: 12 of 17 items for preoperative management, all 5 items for perioperative management, 11 of 14 items for surgical technique, 9 of 15 items for implant selection, 6 of 8 items for bone grafting, 7 of 10 items for blood conservation, 5 of 7 items for postoperative management, all 17 items for postoperative evaluation, and 2 of 4 items for aftercare. Conclusions: Expert consensus was achieved on 74 aspects of the surgical management of AIS in Japan. In implant selection and aftercare, consensus was obtained in less than 70% of the aspects, revealing differences in AIS management between institutions. These findings on AIS surgery in Japan, informed by expert opinion, will conceivably help spine deformity surgeons determine appropriate surgical management of AIS.
Article
Importance Adolescent idiopathic scoliosis (AIS), a spinal curvature of 10° or more, is the most common form of scoliosis, with a prevalence of 1% to 3%. Curves progress in approximately two-thirds of patients with AIS before skeletal maturity, and large curves (>50°) may be associated with adverse health outcomes. Objective To systematically review evidence on benefits and harms of AIS screening for the US Preventive Services Task Force (USPSTF). Data Sources Cochrane Central Register of Controlled Trials, MEDLINE, ERIC, PubMed, CINAHL, and relevant systematic reviews were searched for studies published from January 1966 to October 20, 2016; studies included in a previous USPSTF report were also reviewed. Surveillance was conducted through July 24, 2017. Study Selection Fair- and good-quality studies that evaluated the accuracy of screening children and adolescents aged 10 to 18 years for AIS, the benefits of AIS treatment, the harms of AIS screening or treatment, or long-term health outcomes. Data Extraction and Synthesis Two investigators independently reviewed abstracts and full-text articles and extracted data into evidence tables. Results were qualitatively summarized. Main Outcomes and Measures Health outcomes and spinal curvature in adolescence and adulthood, accuracy of screening for AIS, any harm of AIS screening or treatment. Results Fourteen studies (N = 448 276) in 26 articles were included. Accuracy of AIS screening was highest (93.8% sensitivity; 99.2% specificity) in a cohort study of a clinic-based program using forward bend test, scoliometer, and Moiré topography screening (n = 306 082); accuracy was lower in cohort studies of 6 programs using fewer modalities (n = 141 161). Four controlled studies (n = 587) found evidence for benefit of bracing on curve progression compared with controls. A randomized clinical trial and a nonrandomized trial of exercise treatment (N = 184) found favorable reductions in Cobb angle of 0.67° to 4.9° in the intervention group compared with increases of 1.38° to 2.8° in the control group. Two cohort studies (n = 339) on long-term outcomes found that braced participants reported more negative treatment experience and body appearance compared with surgically treated or untreated participants. A study that combined a randomized clinical trial and cohort design (n = 242) reported harms of bracing, which included skin problems on the trunk and nonback body pains. There was no evidence on the effect of AIS screening on adult health outcomes. Conclusions and Relevance Screening can detect AIS. Bracing and possibly exercise treatment can interrupt or slow progression of curvature in adolescence. However, there is little or no evidence on long-term outcomes for AIS treated in adolescence, the association between curvature at skeletal maturity and adult health outcomes, the harms of AIS screening or treatment, or the effect of AIS screening on adult health outcomes.
