Reducing Time to Diagnosis of Autism Spectrum Disorder Using an Integrated Community Specialty Care Model: A Retrospective Study.

OBJECTIVE: To evaluate a fast-track triage model in an integrated community specialty clinic to reduce the age of diagnosis for patients with autism spectrum disorder (ASD). STUDY DESIGN: A retrospective chart review was performed for patients seen in an integrated community specialty pediatric practice using a fast-track screening and triage model. The percentage of ASD diagnoses, age at diagnosis, and time from referral to diagnosis were evaluated. The fast-track triage model was compared with national and statewide estimates of median age of first evaluation and diagnosis. RESULTS: From January 1, 2020, through December 31, 2021, 189 children with a mean (SD) age of 32.2 (12.4) months were screened in the integrated community specialty. Of these, 82 (43.4%) children were referred through the fast-track triage for further evaluation in the developmental and behavioral pediatrics (DBP) department, where 62 (75.6%) were given a primary diagnosis of ASD. Average wait time from referral to diagnosis using the fast-track triage model was 6 months. Mean (SD) age at diagnosis was 37.7 (13.5) months. The median age of diagnosis by the fast-track triage model was 33 months compared with the national and state median ages of diagnosis at 49 and 59 months, respectively. CONCLUSIONS: With the known workforce shortage in fellowship-trained developmental behavioral pediatricians, the fast-track triage model is feasible and maintains quality of care while resulting in more timely diagnosis, and reducing burden on DBP by screening out cases who did not require further multidisciplinary DBP evaluation as they were appropriately managed by other areas.

Prevalence and Consequences of a Delayed Diagnosis in Multiple Myeloma: A Single Institution Experience.

BACKGROUND: Multiple myeloma (MM) is a disease with unspecific initial symptoms which may lead into a delay in the diagnosis, seemingly increasing the risk of complications and in turn reducing the overall survival (OS). OBJECTIVE: To analyze the consequences of a delayed diagnosis of MM in both the OS and the progression-free survival (PFS) of the patients in a single center in México. METHODS: The study included patients with MM who were diagnosed at Clínica Ruiz, Puebla, México, between 1983 and 2022. According to the time elapsed between the onset of symptoms to the establishment of the definite diagnosis of MM, 4 groups were constructed: 1) Less than 3 months, 2) 3-6 months, 3) 6-12 months, and 4) More than 12 months. RESULTS: About 136 patients had a complete clinical record and at least a 3-month follow up period. A delay in the diagnosis of MM (more than 3 months from the onset of symptoms) was recorded in 92/136 persons (68%). The median follow-up for the whole group was 24.7 months, median OS was 131.4 months, whereas median PFS was 85.4 months. There was a significant trend for being in earlier stages of the disease and being diagnosed within 3 months from the onset of symptoms (P = .049). Both OS and PFS were similar in the patients diagnosed before or after 3 months from the symptoms onset (P = .772). The 6-12 months group was the group with the better median both OS (197.4 months) and DFS (197.4) from the diagnosis. The median OS for the other groups were similar among them. CONCLUSION: A delay in the diagnosis of MM is very frequent in México (68% of cases); despite the fact that there was a significant trend for being in earlier stages of the disease and being diagnosed within 3 months from the onset of symptoms, we did not find a relationship between a delay on the diagnosis of the disease and a higher risk of complications and/or poor prognosis. Possible explanations to these findings are discussed.

Importancia del "diagnóstico temprano" en los niños con cáncer para mejorar el pronóstico: concepto con poco sustento científico.

La mortalidad por cáncer en niños mexicanos no ha disminuido a los niveles informados en países desarrollados. Una explicación frecuentemente declarada es el alto porcentaje (57.3 %) de pacientes diagnosticados en estadios avanzados (III/IV), atribuible a errores en la sospecha o en la metodología empleada, consideración dudosa si se toma en cuenta que el tiempo de diagnóstico y la proporción de estadios avanzados en México son semejantes a los de países desarrollados. En la mayoría de los niños con cáncer, los días transcurridos desde el primer síntoma a momento del diagnóstico oncológico no correlacionan con el estadio clínico y tampoco con la probabilidad de supervivencia. El éxito en la supervivencia depende en gran medida del tratamiento integral (específico y de la atención a las complicaciones). Esta visión obliga a estrategias dirigidas principalmente a invertir más recursos en opciones terapéuticas eficaces y eficientes, capacitación oncológica integral del equipo de salud (médicos, enfermeras, técnicos), tecnologías diagnósticas, fomento a la colaboración interinstitucional e internacional y apoyo socioeconómico a las familias durante el proceso terapéutico.Cancer mortality in Mexican children has not decreased to the levels reported in developed countries. A commonly proposed explanation is the high percentage (53.7%) of patients diagnosed at advanced stages (III/IV), which is attributed to erroneous assumptions or mistakes in the diagnostic approach ­a questionable consideration taking into account that both time to diagnosis and the proportion of advanced stage cases in Mexico are similar to those in developed countries. In most cancer cases in children, the number of days elapsed from the moment of the first symptom to the cancer diagnosis is not correlated with clinical stage, and neither with the probability of survival. Survival success largely depends on comprehensive treatment (specific and for the care of complications). This view calls for strategies mainly aimed at spending more resources on efficacious and efficient therapeutic strategies, comprehensive oncology training of healthcare personnel (physicians, nurses and technicians), diagnostic technologies, promotion of interinstitutional and international collaboration and socioeconomic support to families during the therapeutic process.
