Pathways of healthcare utilisation in patients with suspected adolescent idiopathic scoliosis: a cross-sectional study

Inter-Establishment Complex Musculoskeletal Care Pathways in Montreal: Timeline of a Collaboration Involving a Research Team Within a Continuous Quality Improvement Initiative

Children and adolescents with complex musculoskeletal conditions may receive health care that requires at least 1 transfer between 4 specialized pediatric establishments in the Montreal region (Québec, Canada). This may result in challenges in navigating the system. A collaborative approach, aiming to make the inter-establishment care pathways seamless and to improve the integration of musculoskeletal health services, brought together key stakeholders including a research team. The aim of this paper is to describe the timeline of the collaborative approach's key milestones and activities and, more specifically, to describe the context, process, and outputs of the involvement of researchers in support of a continuous quality improvement project based on an integrated approach. The descriptive timeline was constructed from a qualitative document analysis of the project-related gray literature (n = 80 documents) and was validated and interpreted with key stakeholders. The results showed how the collaborative project was set up and operated, as well as what solutions were developed and implemented. The strategies on how the research team was involved in the integrated approach in addition to its research activities were also described. Conclusions suggest practice recommendations for creating change processes by integrating research, service evaluation and clinical audit into quality improvement projects.

Parents can reliably and accurately detect trunk asymmetry using an inclinometer smartphone app

PURPOSE

An inclinometer smartphone application has been developed to enable the measurement of the angle of trunk inclination (ATI) to detect trunk surface asymmetry. The objective was to determine the reliability and validity of the smartphone app in the hands of non-professionals.

METHODS

Three non-professional observers and one expert surgeon measured maximum ATI twice in a study involving 69 patients seen in the spine clinics to rule out scoliosis or for regular follow-up (10-18 y.o., Cobb [0°-58°]). Observers were parents not familiar with scoliosis screening nor use of an inclinometer. They received training from a 4-minute video. Intra and inter-observer reliability was determined using the generalizability theory and validity was assessed from intraclass correlation coefficients (ICC), agreement with the expert on ATI measurements using Bland-Altman analysis, and correct identification of the threshold for consultation (set to ≥6° ATI).

RESULTS

Intra-observer and inter-observer reliability coefficients were excellent ϕ = 0.92. The standard error of measurement was 1.5° (intra-observer, 2 measurements) meaning that a parent may detect a change of 4° between examinations 95% of the time. Comparison of measurements between non-professionals and the expert resulted in ICC varying from 0.82 [0.71-0.88] to 0.84 [0.74-0.90] and agreement on the decision to consult occurred in 83 to 90% of cases.

CONCLUSION

The use of a smartphone app resulted in excellent reliability, sufficiently low standard error of measurement (SEM) and good validity in the hands of non-professionals. The device and the instructional video are adequate means to allow detection and regular examination of trunk asymmetries by non-professionals.

Definition and conceptualization of the patient-centered care pathway, a proposed integrative framework for consensus: a Concept analysis and systematic review

BACKGROUND

Confusion exists over the definition of the care pathway concept and existing conceptual frameworks contain various inadequacies which have led to implementation difficulties. In the current global context of rapidly changing health care systems, there is great need for a standardized definition and integrative framework that can guide implementation. This study aims to propose an accurate and up-to-date definition of care pathway and an integrative conceptual framework.

METHODS

An innovative hybrid method combining systematic review, concept analysis and bibliometric analysis was undertaken to summarize qualitative, quantitative, and mixed-method studies. Databases searched were PubMed, Embase and ABI/Inform. Methodological quality of included studies was then assessed.

RESULTS

Forty-four studies met the inclusion criteria. Using concept analysis, we developed a fine-grained understanding, an integrative conceptual framework, and an up-to-date definition of patient-centered care pathway by proposing 28 subcategories grouped into seven attributes. This conceptual framework considers both operational and social realities and supports the improvement and sustainable transformation of clinical, administrative, and organizational practices for the benefit of patients and caregivers, while considering professional experience, organizational constraints, and social dynamics. The proposed attributes of a fluid and effective pathway are (i) the centricity of patients and caregivers, (ii) the positioning of professional actors involved in the care pathway, (iii) the operation management through the care delivery process, (iv) the particularities of coordination structures, (v) the structural context of the system and organizations, (vi) the role of the information system and data management and (vii) the advent of the learning system. Antecedents are presented as key success factors of pathway implementation. By using the consequences and empirical referents, such as outcomes and evidence of care pathway interventions, we went beyond the single theoretical aim, proposing the application of the conceptual framework to healthcare management.

CONCLUSIONS

This study has developed an up-to-date definition of patient-centered care pathway and an integrative conceptual framework. Our framework encompasses 28 subcategories grouped into seven attributes that should be considered in complex care pathway intervention. The formulation of these attributes, antecedents as success factors and consequences as potential outcomes, allows the operationalization of this model for any pathway in any context.

Educating Parents Improves Their Ability to Recognize Adolescent Idiopathic Scoliosis: A Diagnostic Accuracy Study

(1) In countries where scoliosis screening programs ended, the responsibility for detection shifted from healthcare professionals to parents. Since recognizing scoliosis is difficult for parents, more patients are presenting late. Increased awareness of scoliosis may favor earlier detection. This study examines the effect of educating parents to recognize scoliosis. (2) In this cross-sectional study a consecutive group of parents completed a digital assessment. They had to complete two identical series of fourteen cases (eight with scoliosis and six without). Each case displayed two photographs of the child’s back; one in standing position and one during forward-bending. Based on visual inspection, parents had to indicate if the child had to be referred to a physician. After assessing the first series, information was given on how to detect scoliosis. Subsequently, parents assessed the second series of cases. Sensitivity and specificity were calculated before and after education. (3) A total of 100 parents completed the assessment. The sensitivity to detect scoliosis was slightly but significantly higher after education (68.8% versus 74.0%; p = 0.002), while specificity was not (74.0% versus 74.8%; p = 0.457). (4) This study showed that educating parents improved their ability to recognize scoliosis without increasing the false positive referral rate. Although written instructions can bridge the gap with professional screening programs, the overall sensitivity in this study remained low. Therefore, education can improve the awareness and ability to detect scoliosis, but will not replace screening by professionals.

Screening for adolescent idiopathic scoliosis is more accurate when performed by healthcare professionals compared to untrained parents: a diagnostic accuracy study

BACKGROUND

Many countries ended their professional scoliosis screening due to ongoing controversies. Discontinuation resulted in a shift of screening responsibility from trained healthcare professionals to untrained parents.

PURPOSE

To compare the diagnostic accuracy of picture-based scoliosis screening between parents and healthcare professionals.

METHODS

In this cross-sectional diagnostic accuracy study, parents and healthcare professionals assessed pictures of 28 children (20 AIS & 8 non-scoliosis). Each child had two photographs (standing position & full-flexion during forward-bending test) that were presented simultaneously. Lumbar and thoracic curves were represented with a range in severity (10 to > 40°). The assessors had to answer whether they detected an abnormality that ought to be referred to a specialist. Measures of accuracy were calculated for both groups and various curve severities.

RESULTS

All pictures were assessed by 101 parents and 122 healthcare professionals. The sensitivity for detecting scoliosis was significantly lower in untrained parents (63.8%, [95% CI: 61.7-65.9%]) compared to healthcare professionals (73.4%, [95% CI: 71.6-75.2%]; p < 0.001), while the specificity was not significantly different (63.6%, [95% CI: 60.2-66.9%] vs. 65.3%, [95% CI: 62.2-68.3%]; p = 0.49). Healthcare professionals consistently recognized the gibbus as a warning sign when referring patients, while untrained parents highlighted various regions, including the spine, gibbus and scapula regions.

CONCLUSION

The sensitivity of screening for scoliosis was significantly lower when it was performed by parents, while the false-positive rate was similar to healthcare professionals. The window of opportunity for conservative treatment may be missed when parents rather than professionals are responsible for screening.

Inappropriate use of clinical practices in Canada: a systematic review

Background:

Inappropriate health care leads to negative patient experiences, poor health outcomes and inefficient use of resources. We aimed to conduct a systematic review of inappropriately used clinical practices in Canada.

Methods:

We searched multiple bibliometric databases and grey literature to identify inappropriately used clinical practices in Canada between 2007 and 2021. Two team members independently screened citations, extracted data and assessed methodological quality. Findings were synthesized in 2 categories: diagnostics and therapeutics. We reported ranges of proportions of inappropriate use for all practices. Medians and interquartile ranges (IQRs), based on the percentage of patients not receiving recommended practices (underuse) or receiving practices not recommended (overuse), were calculated. All statistics are at the study summary level.

Results:

We included 174 studies, representing 228 clinical practices and 28 900 762 patients. The median proportion of inappropriate care, as assessed in the studies, was 30.0% (IQR 12.0%–56.6%). Underuse (median 43.9%, IQR 23.8%–66.3%) was more frequent than overuse (median 13.6%, IQR 3.2%–30.7%). The most frequently investigated diagnostics were glycated hemoglobin (underused, range 18.0%–85.7%, n = 9) and thyroid-stimulating hormone (overused, range 3.0%–35.1%, n = 5). The most frequently investigated therapeutics were statin medications (underused, range 18.5%–71.0%, n = 6) and potentially inappropriate medications (overused, range 13.5%–97.3%, n = 9).

Interpretation:

We have provided a summary of inappropriately used clinical practices in Canadian health care systems. Our findings can be used to support health care professionals and quality agencies to improve patient care and safety in Canada.

Trends in Incidence of Adolescent Idiopathic Scoliosis: A Modern US Population-based Study

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.

Scoliosis Screening

The national recommendations for school screening programs for scoliosis in the United States have undergone a shift in perspective over the past two decades. In 2004, the United States Preventive Services Task Force recommended against screening programs but changed its recommendation to be inconclusive in 2018. Early diagnosis of scoliosis can allow for close monitoring of the deformity and early initiation of bracing treatment when appropriate, with the goal of preventing costly and invasive surgical intervention. Several different diagnostic tools are available, including Adam's forward bending test alone, Adam's forward bending test with scoliometry, the humpometer, and Moiré topography, each with varying degrees of sensitivity and specificity. Controversy prevails over the cost efficacy of screening programs and possible unnecessary exposure of adolescents to radiation for confirmatory radiographs after a positive screening test. However, the recent definitive evidence of bracing treatment efficacy in slowing the progression of scoliotic curves and preventing the need for surgery indicates that school screening programs may still have a role in allowing early diagnosis.

Healthcare disparities in adolescent idiopathic scoliosis: the impact of socioeconomic factors on Cobb angle

STUDY DESIGN

Retrospective chart review.

OBJECTIVES

The aim of this study is to assess the role of insurance type, geographic socioeconomic status, and ethnicity in AIS disease severity in a state with mandated scoliosis screenings. Early detection of adolescent idiopathic scoliosis (AIS) is associated with reduced curve progression, surgical treatment, and long-term sequelae. Type of insurance, ethnicity, and socioeconomic status are important determinants in healthcare access.

METHODS

Data were obtained for 561 AIS patients aged 10-18 years, living within a single county, and presenting to a single healthcare system for initial evaluation of AIS between 2010 and 2016 that met inclusion criteria. Demographic data including gender, age, self-reported ethnicity, insurance, and zip code were collected. Outcome measures included Cobb angle, curve severity, and referral delay. A single fellowship-trained pediatric orthopedic surgeon calculated presenting Cobb angle for each case. Zip code was used as a proxy for household income level. Independent sample t tests, analysis of variance and covariance, and χ² analysis were used to determine the significant differences and correlations.

RESULTS

Female patients (n = 326, CA = 22.4°) had significantly greater Cobb angle measurements compared with male patients (n = 117, CA = 18.1°). Patients with government-supported insurance had significantly higher Cobb angles (CA = 22.1°) than privately insured patients (CA = 19.2°) but were both classified within the "mild" range clinically, and are likely not clinically significant. There was no correlation between income level and Cobb angle. Referral delay and Cobb angle severity did not vary by age, income, or insurance. A χ² analysis showed no association between Cobb angle and race.

CONCLUSIONS

Cobb angle severity was not influenced by SES factors, including ethnicity and household income.

Association between lay perception of morbidity and appropriateness of specialized health care use in adolescent idiopathic scoliosis

In absence of school scoliosis screening programs (SSSP) in Canada, this study examined the relationships between the lay person's perception of morbidity and the appropriateness of referral in orthopedics. A cross-sectional study was conducted with all children consecutively referred in orthopedics for suspected scoliosis. The 831 participants were classified as Appropriate, Late, or Inappropriate referrals for the orthopedic setting. Perceived morbidity was operationalized by: the scoliosis detection originator, the perceptions of the seriousness of the condition and urgency to consult a physician, the perception of the general health, as well as Visible Back Deformity, Self-image, and Pain. Direct associations between the perceived morbidity and the appropriateness of referral were found in all scoliosis-specific measures; the most discriminant variable was Visible Back Deformity. Lay perceived morbidity is a good indicator of the objective morbidity, and thus reflects in the appropriateness of referral status. The important role of the lay persons in symptoms appraisal does not however insure appropriate referral. Searching for alternatives to SSSP would wisely include a health promotion and medical management program. Statement of Clinical Significance: Perceived morbidity by the lay persons is strongly associated with the objectively evaluated severity of scoliosis deformity. Therefore, in absence of SSSP, lay person awareness plays an important role in symptom recognition and search for care. © 2019 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.

Low hospital referral rates of school scoliosis screening positives in an urban district of mainland China

Significant prevalence rates of adolescent scoliosis in China were suggested in previous studies. However, school screenings for adolescent scoliosis have been suspended due to low rates of positive detection under the past screening system in China. The present study was undertaken to screen for adolescent scoliosis in middle school students under a modern assessment system in a district of Shanghai. We performed a population-based, cross-sectional study of a middle school scoliosis screening program in the Jingan district. In 2015, schoolchildren were initially screened by visual inspection of clinical signs and the forward-bending test. Suspected cases were referred for radiography in hospital for scoliosis diagnosis. A total of 5327 middle school students (grades 6-8) were screened with 520 (9.76%) positives (the positive rates of girls and boys at 15.28% and 4.59%, respectively) and no statistically significant difference among grades. Only 301 positives (57.9%) followed the referral for hospital radiography. There were 102 cases (33.9%) that were diagnosed with scoliosis by radiography criteria (Cobb angle ≥10°) including mild scoliosis (Cobb 10-25) for 94 cases and moderate scoliosis (Cobb 25-40) for 8 cases, and false-positives (Cobb 0) for 39 cases. The putative prevalence rate was estimated as 1.9% from the referred students. Under an accurate and modern assessment system, school screenings can detect scoliosis at a significant rate, but awareness of scoliosis risks is needed for residents in China to take up referrals for hospital diagnosis after school screenings.
