RESUMEN

We present an unusual etiology of primary renal allograft dysfunction attributed to myeloma cast nephropathy in a patient with no history of multiple myeloma before kidney transplant. The patient, a 54-year-old woman, had been on hemodialysis for 6 months before transplant for presumed diabetic nephropathy; she developed graft dysfunction immediately after transplant. Graft biopsy specimens were consistent with myeloma cast nephropathy, and she was treated with bortezomib, cyclophosphamide, and dexamethasone. She achieved a complete hematological response and regained excellent graft function 3 months after transplant. The patient then received autologous stem cell transplant 8 months after kidney transplant. To our knowledge, this is the second report of a successful graft outcome after chemotherapy and the first report treated with autologous stem cell transplantation after remission of monoclonal disease.

RESUMEN

A previously healthy man developed pulmonary symptoms 2 weeks after starting treatment with a tumour necrosis factor (TNF) inhibitor. A negative interferon-gamma release assay (IGRA) test was obtained prior to TNF inhibitor exposure, without consideration of the fact that the patient was already immunosuppressed and had a previous positive IGRA test 17 months earlier. The patient was treated for pneumonia twice but did not achieve remission. His physical health progressively deteriorated over the following months. Malignancy was suspected but not found. Eight months after the onset of symptoms, Mycobacterium tuberculosis was found in samples from mediastinal lymph nodes, and the patient was diagnosed with multidrug-resistant tuberculosis (MDR-TB).This case illustrates the diagnostic challenge of TB, the need to raise awareness of the increased risk of TB in patients treated with TNF inhibitors and the need to increase knowledge regarding the effect of immunosuppressive agents on IGRA tests.

RESUMEN

BACKGROUND: To investigate the effect of different working periods on missed diagnoses in patients with colorectal polyps in colonoscopy. METHODS: We conducted a retrospective analysis of patients who were diagnosed with colorectal polyps during colonoscopy in an outpatient department between July and December 2022. These patients were subsequently hospitalized for resection during this period. Patients with missed diagnoses were those who had newly discovered polyps in a second colonoscopy. The working periods were categorized as work, near the end of work, and delayed work, respectively, in the morning and afternoon. RESULTS: A total of 482 patients were included, and the miss rate of diagnosis was 48.1% (232/482), mainly in the transverse colon (25%), and the ascending colon (23%). Patient age was a risk factor for the miss rate of diagnosis (OR = 1.025, 95%CI: 1.009-1.042, P = 0.003) and was also associated with the number of polyps detected for the first colonoscopy (χ2 = 18.196, P = 0.001). The different working periods had no statistical effect on the missed rate of diagnosis (χ2 = 1.998, P = 0.849). However, there was an increasing trend in miss rates towards the end of work and delayed work periods, both in the morning and afternoon. The highest miss rate (60.0%) was observed during delayed work in the afternoon. Additionally, poor bowel preparation was significantly more common during delayed work in the afternoon. CONCLUSIONS: The increasing trend in miss rates towards the end of work and delayed work periods deserves clinical attention. Endoscopists cannot always stay in good condition under heavy workloads.

RESUMEN

OBJECTIVES: Radiotherapy is the primary treatment for nasopharyngeal carcinoma, but it frequently leads to radiotherapy-induced temporal lobe injury (RTLI). Magnetic resonance imaging (MRI) is the main diagnostic method for RTLI after radiotherapy for nasopharyngeal carcinoma, but it is prone to missed diagnoses. This study aims to investigate the causes of missed diagnoses of RTLI in nasopharyngeal carcinoma patients undergoing MRI after radiotherapy. METHODS: Clinical and MRI data from nasopharyngeal carcinoma patients diagnosed and treated with radiotherapy at Xiangya Hospital of Central South University, from January 2010 to April 2021, were collected. Two radiologists reviewed all head and neck MRIs (including nasopharyngeal and brain MRIs) before and after radiotherapy of identify cases of late delayed response-type RTLI for the first time. If the original diagnosis of the initial RTLI in nasopharyngeal carcinoma patients did not report temporal lobe lesions, it was defined as a missed diagnosis. The first diagnosis of RTLI cases was divided into a missed diagnosis group and a non-missed diagnosis group. Clinical and imaging data were compared between the 2 groups, and multivariate logistic regression analysis was used to identify independent risk factors for MRI missed diagnoses of initial RTLI. RESULTS: A total of 187 nasopharyngeal carcinoma with post-radiotherapy RTLI were included. The original diagnostic reports missed 120 cases and accurately diagnosed 67 cases, with an initial RTLI diagnosis accuracy rate of 35.8% and a missed diagnosis rate of 64.2%. There were statistically significant differences between the missed diagnosis group and the non-missed diagnosis group in terms of lesion size, location, presence of contralateral temporal lobe lesions, white matter high signal, cystic degeneration, hemorrhage, fluid attenuated inversion recovery (FLAIR), and examination site (all P<0.05). Multivariate logistic regression analysis showed that lesions ≤25 mm, non-enhancing lesions, lesions without cystic degeneration or hemorrhage, lesions located only in the medial temporal lobe, and MRI examination only of the nasopharynx were independent risk factors for missed MRI diagnosis of initial RTLI (all P<0.05). CONCLUSIONS: The missed diagnosis of initial RTLI on MRI is mainly related to lesion size and location, imaging characteristics, and MRI examination site.

RESUMEN

OBJECTIVE: To retrospectively analyze the causes of missed diagnosis of clinically significant PCa (csPCa) by targeted biopsy (TB). METHODS: This retrospective study included 652 males aged (71.32 ± 16.53) years with elevated PSA and abnormal MRI signals detected in our hospital from June 2018 to December 2020. We further examined the patients by transperineal prostatic TB and systematic biopsy (SB), analyzed the detection rates of PCa and csPCa by TB and SB, and investigated the causes of missed diagnosis of csPCa in TB using the fishbone diagram. RESULTS: The total detection rate of PCa and csPCa by TB combined with SB was 45.7% (298/652), and that of csPCa was 37.4% (244/652), with 38 cases of csPCa missed in TB, including 23 cases of negative TB and 15 cases of low ISUP grade. The causes of missed diagnosis of csPCa by TB included low MRI image quality, PSA density ≤0.15 ng/ml/cm3, target area <10 mm, and PI-RADS 2 score ≤3. The detection rate of csPCa by TB alone was 31.6%, which was increased by 5.8% (P = 0.027) when TB combined with SB. CONCLUSION: TB combined with SB yields a higher detection rate of csPCa than either used alone. Missed diagnosis of csPCa by TB is closely related to the characteristics of tumor and MR image of the target area.

RESUMEN

INTRODUCTION: The incidence of esophageal cancers is increasing in many Western countries and the rate of missed esophageal cancers (MEC) at upper endoscopy is of concern. We aimed to calculate the MEC rate and identify factors associated with MEC. METHODS: This was a retrospective population-based cohort study including 613 patients diagnosed with esophageal cancer in Central Norway 2004-2021. MEC was defined as esophageal cancer diagnosed 6-36 months after a non-diagnostic upper endoscopy. Patient characteristics, tumor localization, histological type and cTNM stage were recorded. Symptoms, endoscopic findings, use of sedation and endoscopists experience at the endoscopy prior to esophageal cancer diagnosis and at the time of diagnosis were recorded. The association between these factors and MEC was assessed. RESULTS: Forty-nine (8.0%) of 613 cancers were MEC. There was a significant increase in annual numbers of esophageal cancer (p < 0.001) as well as of MEC (p = 0.009), but MEC rate did not change significantly (p = 0.382). The median time from prior upper endoscopy to MEC diagnosis was 22.9 (12.1-28.6) months. MEC patients were older and were diagnosed with disease with a lower cTNM stage and cT category than non-missed cancers, whereas tumor localization and histological type were similar between the groups. The use of sedation or endoscopist experience did not differ between the endoscopy prior to esophageal cancer diagnosis and at the time of diagnosis. High proportions of MEC patients had Barrett's esophagus (n = 25, 51.0%), hiatus hernia (n = 26, 53.1%), esophagitis (n = 10, 20.4%) or ulceration (n = 4, 8.2%). Significant proportions of MECs were diagnosed after inappropriate follow-up of endoscopic Barrett's esophagus, histological dysplasia or ulcerations. CONCLUSIONS: The annual number of MEC increased during the study period, while the MEC rate remained unchanged. Endoscopic findings related to gastroesophageal reflux disease such as esophagitis and Barrett's esophagus were identified in a high proportion of patients with subsequent MECs. Cautious follow-up of these patients could potentially reduce MEC-rate.

RESUMEN

BACKGROUND: The WHO presented the initiative: "Global elimination of congenital syphilis (CS): rationale and strategies for action". It establishes that CS is a preventable disease that can be eliminated. OBJECTIVE: To estimate the proportion of missed opportunities for prevention (MOP) of (CS). MATERIAL AND METHODS: Cross-sectional study. We studied women with children with confirmed diagnosis of CS (NOM-039-SSA2-2002) in the Mexican Social Security Institute in Jalisco from 01/01/2016 to 08/01/2022. The clinical records of the mother, the newborn and the epidemiological study (ES) were reviewed. Each case was classified into one of the MOP categories. RESULTS: 52 cases were reported: 46.2 % (n = 24) were ruled out, 34.6 % (n = 18) confirmed, 15.4 % (n = 8) unknown and 3.8 % (n = 2) probable cases. The HIV test was performed in 61.1 % (n = 11) and syphilis in 72.2 % (n = 13) of the mothers. The MOP in 27.8 % (n = 5) was inadequate treatment or omission of maternal treatment despite a timely diagnosis of syphilis. Treatment was inadequate in 63.6 % (n = 7) of the women who received it. CONCLUSION: The classification of MOP identifies gaps in CS prevention and can guide stakeholders, policy makers and public health prevention programs to reduce the incidence of CS.


ANTECEDENTES: La Organización Mundial de la Salud estableció que la sífilis congénita es una enfermedad prevenible que puede eliminarse. OBJETIVO: Estimar la proporción de oportunidades perdidas en la prevención (OPP) de la sífilis congénita. MATERIAL Y MÉTODOS: Estudio transversal descriptivo. Se eligieron mujeres en cuyos hijos recién nacidos se identificó sífilis congénita entre 2016 y 2022. Se revisaron los expedientes clínicos de la madre, el recién nacido y el estudio epidemiológico. Cada caso se clasificó en una de las categorías de las OPP. RESULTADOS: Se notificaron 52 casos: 46.2 % (n = 24) fue descartado, 34.6 % (n = 18) confirmado, 15.4 % (n = 8) desconocido y 3.8 % (n = 2) probable. Las pruebas para identificar infección por VIH y sífilis se realizaron en 61.1 % (n = 11) y 72.2 % de las madres (n = 13). La OPP en 27.8 % (n = 5) consistió en el tratamiento inadecuado u omisión de tratamiento materno a pesar de diagnóstico oportuno de la sífilis. De quienes recibieron tratamiento, en 63.6 % fue inadecuado (n = 7). CONCLUSIÓN: La clasificación de OPP de sífilis congénita permite identificar brechas en la prevención y dirigir intervenciones de salud pública hacia las principales causas para reducir la incidencia.

RESUMEN

The ENDOANGEL (EN) computer-assisted detection technique has emerged as a promising tool for enhancing the detection rate of colorectal adenomas during colonoscopies. However, its efficacy in identifying missed adenomas during subsequent colonoscopies remains unclear. Thus, we herein aimed to compare the adenoma miss rate (AMR) between EN-assisted and standard colonoscopies. Data from patients who underwent a second colonoscopy (EN-assisted or standard) within 6 months between September 2022 and May 2023 were analyzed. The EN-assisted group exhibited a significantly higher AMR (24.3% vs 11.9%, P = .005) than the standard group. After adjusting for potential confounders, multivariable analysis revealed that the EN-assisted group had a better ability to detect missed adenomas than the standard group (odds ratio = 2.89; 95% confidence interval = 1.14-7.80, P = .029). These findings suggest that EN-assisted colonoscopy represents a valuable advancement in improving AMR compared with standard colonoscopy. The integration of EN-assisted colonoscopy into routine clinical practice may offer significant benefits to patients requiring hospital resection of lesions following adenoma detection during their first colonoscopy.

RESUMEN

BACKGROUND Inferior vena cava (IVC) injury is a potentially fatal injury with a high mortality rate of 34-70%. In cases in which the patient's condition is stable, diagnosis by computed tomography (CT) is the criterion standard. Findings on CT include retroperitoneal hematoma around the IVC, extravasation of contrast medium, and abnormal morphology of the IVC. We report a case of an IVC injury that could not be diagnosed by preoperative CT examination and could not be immediately detected during laparotomy. CASE REPORT A 73-year-old woman had stabbed herself in the neck and abdomen at home using a knife. When she arrived at our hospital, we found a stab wound several centimeters long on her abdomen and a cut approximately 15 cm long on her neck. We activated the massive transfusion protocol because she was in a condition of hemorrhagic shock. After blood transfusion and blood pressure stabilization, contrast-enhanced computed tomography (CT) revealed a small amount of fluid in the abdominal cavity. An otorhinolaryngologist performed successful drainage and hemostasis, and a laparotomy was performed. Gastric injury and mesentery injury of the transverse colon were identified and repaired with sutures. Subsequent search of the retroperitoneum revealed massive bleeding from an injury to the inferior vena cava (IVC). The IVC was repaired. Postoperative progress was good, and she was discharged from the hospital 65 days after her injuries. CONCLUSIONS We experienced a case of penetrating IVC injury, which is a rare trauma. Occult IVC injury may escape detection by preoperative CT examination or during laparotomy.

RESUMEN

INTRODUCTION: There is limited evidence about factors related to the timeliness of dementia diagnosis in healthcare settings. METHODS: In five prospective cohorts at Rush Alzheimer's Disease Center, we identified participants with incident dementia based on annual assessments and examined the timing of healthcare diagnoses in Medicare claims. We assessed sociodemographic, health, and psychosocial correlates of timely diagnosis. RESULTS: Of 710 participants, 385 (or 54%) received a timely claims diagnosis within 3 years prior to or 1 year following dementia onset. In logistic regressions accounting for demographics, we found Black participants (odds ratio [OR] = 2.15, 95% confidence interval [CI]: 1.21 to 3.82) and those with better cognition at dementia onset (OR = 1.48, 95% CI: 1.10 to 1.98) were at higher odds of experiencing a diagnostic delay, whereas participants with higher income (OR = 0.89, 95% CI: 0.81 to 0.97) and more comorbidities (OR = 0.94, 95% CI: 0.89 to 0.98) had lower odds. DISCUSSION: We identified characteristics of individuals who may miss the optimal window for dementia treatment and support. HIGHLIGHTS: We compared the timing of healthcare diagnosis relative to the timing of incident dementia based on rigorous annual evaluation. Older Black adults with lower income, higher cognitive function, and fewer comorbidities were less likely to be diagnosed in a timely manner by the healthcare system.

RESUMEN

Poppers maculopathy is a complication of alkyl nitrate (poppers) inhalation. It presents with non-specific symptoms and variable signs, which can make it difficult to diagnose. We present a case of coexisting cataract and poppers maculopathy in a patient. He had vague visual symptoms that were attributed entirely to his cataract and he went on to have cataract surgery. Suboptimal postoperative visual acuity and normal clinical examination triggered further investigation with spectral-domain optical coherence tomography (SD-OCT), after which poppers maculopathy was diagnosed. We highlight the importance of performing OCT in the preoperative assessment of a cataract patient, especially where the cataract is mild and may not fully account for symptoms. The patient showed complete visual recovery on drug cessation despite ongoing maculopathy on OCT scans.

RESUMEN

BACKGROUND: Missed early gastric cancer (MEGC) is prevalent during esophagogastroduodenoscopy (EGD), which is the first-line recommended strategy for detecting early gastric cancer (EGC). Hence, we explored the risk factors for MEGC and different types of MEGC, based on the endoscopic resected population. METHODS: This retrospective, case-control study was conducted at Nanjing Drum Tower Hospital (NJDTH). We included patients who were diagnosed with EGC during screening EGD, underwent endoscopic resection, and were confirmed by postoperative pathology at the NJDTH from January 2014 to December 2021, and classified them into different types according to the different root causes of misses. Univariable, multivariable, subgroup and propensity score analyses were used to explore the risk factors for MEGC and different types of MEGC. RESULTS: A total of 447 patients, comprising 345 with initially detected early gastric cancer (IDEGC) and 102 with MEGC, were included in this study. Larger size (≥ 1 cm) (OR 0.45, 95% CI 0.27-0.74, P = 0.002) and invasion depth of submucosa (OR 0.26, 95% CI 0.10-0.69, P = 0.007) were negatively associated with MEGC. Use of sedation (OR 0.32, 95% CI 0.20-0.52, P < 0.001) and longer observation time (OR 0.60, 95% CI 0.37-0.96, P = 0.034) exhibited protective effect on MEGC. CONCLUSIONS: Smaller and more superficial EGC lesions are more susceptible to misdiagnosis. The use of sedation and prolonged observation time during EGD could help reduce the occurrence of MEGC.

RESUMEN

Tuberculosis (TB) is the leading infectious cause of mortality in sub-Saharan Africa (SSA); the high prevalence of TB in this region is due to human immunodeficiency virus (HIV)-coinfection. Despite the advent of modalities to diagnose TB, undiagnosed TB-related deaths among HIV-infected patients remain significantly high. This systematic review aims at characterizing missed TB cases from postmortem studies. This review informs on the burden of TB missed diagnosis and highlights the need of improving TB case-finding strategies, especially among the high-risk groups and early TB therapy initiation to keeping in with the World Health Organization's end TB strategy. We searched PubMed, Cochrane, Web of Science, and African journals online for studies that looked into missed TB cases following postmortem using the following key terms: postmortem, TB diagnosis, and HIV; we included cross-sectional and cohorts from 1980 in the English language that were carried out in SSA among adults' population. Authors used the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines for reporting, the quality of the included studies was assessed using the Newcastle-Ottawa Scale for observational studies, and STATA 17.0 software was used for analysis. This study was registered in the International Prospective Register of Systematic Reviews with registration number CRD42024507515. The combined prevalence of postmortem missed TB diagnosis among the 6025 participants was 27.13% (95% confidence interval [CI] =14.52-41.89), with a high level of heterogeneity at 98.65% (P < 0.001). The prevalence varied significantly across the included studies, ranging from 1.21% (95% CI = 0.93-1.59) in the general population to 66.67% (95% CI = 50.98-79.37) in people living with HIV (PLWHIV). This current literature suggests that SSA is a region with a high prevalence of missed TB cases but with significant variations between countries. In addition, this study confirms a high number of missed TB infections within the PLWHIV. These results highlight the immediate need for targeted screening and diagnosis strategies and relevant policies.

RESUMEN

Pancreatic ductal adenocarcinoma (PDAC) has poor prognosis mostly due to the advanced stage at which disease is diagnosed. Early detection of disease at a resectable stage is, therefore, critical for improving outcomes of patients. Prior studies have demonstrated that pancreatic abnormalities may be detected on CT in up to 38% of CT studies 5 years before clinical diagnosis of PDAC. In this review, we highlight commonly missed signs of early PDAC on CT. Broadly, these commonly missed signs consist of small isoattenuating PDAC without contour deformity, isolated pancreatic duct dilatation and cutoff, focal pancreatic enhancement and focal parenchymal atrophy, pancreatitis with underlying PDAC, and vascular encasement. Through providing commentary on demonstrative examples of these signs, we demonstrate how to reduce the risk of missing or misinterpreting radiological features of early PDAC.

RESUMEN

Improved cancer screening and treatment programs have led to an increased survivorship of patients with cancer, but consequently also to the rise in number of individuals with multiple primary tumors (MPT). Germline testing is the first approach investigating the cause of MPT, as a positive result provides a diagnosis and proper clinical management to the affected individual and their family. Negative or inconclusive genetic results could suggest non-genetic causes, but are negative genetic results truly negative? Herein, we discuss the potential sources of missed genetic causes and highlight the trove of knowledge MPT can provide. See related article by Borja et al., p. 209.

BACKGROUND/OBJECTIVE: Neurosurgery emphasizes the criticality of accurate differential diagnoses, with diagnostic delays posing significant health and economic challenges. As large language models (LLMs) emerge as transformative tools in healthcare, this study seeks to elucidate their role in assisting neurosurgeons with the differential diagnosis process, especially during preliminary consultations. METHODS: This study employed 3 chat-based LLMs, ChatGPT (versions 3.5 and 4.0), Perplexity AI, and Bard AI, to evaluate their diagnostic accuracy. Each LLM was prompted using clinical vignettes, and their responses were recorded to generate differential diagnoses for 20 common and uncommon neurosurgical disorders. Disease-specific prompts were crafted using Dynamed, a clinical reference tool. The accuracy of the LLMs was determined based on their ability to identify the target disease within their top differential diagnoses correctly. RESULTS: For the initial differential, ChatGPT 3.5 achieved an accuracy of 52.63%, while ChatGPT 4.0 performed slightly better at 53.68%. Perplexity AI and Bard AI demonstrated 40.00% and 29.47% accuracy, respectively. As the number of considered differentials increased from 2 to 5, ChatGPT 3.5 reached its peak accuracy of 77.89% for the top 5 differentials. Bard AI and Perplexity AI had varied performances, with Bard AI improving in the top 5 differentials at 62.11%. On a disease-specific note, the LLMs excelled in diagnosing conditions like epilepsy and cervical spine stenosis but faced challenges with more complex diseases such as Moyamoya disease and amyotrophic lateral sclerosis. CONCLUSIONS: LLMs showcase the potential to enhance diagnostic accuracy and decrease the incidence of missed diagnoses in neurosurgery.

RESUMEN

BACKGROUND: We aimed to retrospectively measure the incidence of missed orbital blowout fracture diagnosis in primary examinations of patients with surgically treated fractures, to identify the causes of the diagnostic oversight, and to describe the clinical manifestations of the fractures. MATERIAL AND METHODS: A retrospective cohort of all patients with unilateral orbital blowout fractures who underwent subsequent surgical fracture reduction at the Department of Oral and Maxillofacial Diseases, Helsinki University Hospital, from January 2011 to July 2021, was gathered. Demographics, fracture type, associated injuries, clinical manifestations, reconstruction indication, diagnostic delay, and causes of fractures were analysed. For statistical analysis, Fisher's exact test, unpaired t-test, and the Wilcoxon Rank Sum were used. Significance was set at P˂0.05. RESULTS: Fracture diagnosis was missed in 26 (13%) of 207 patients: in 40% of patients aged under 18 years and in 10% of patients aged 18 years or over (P=0.005). Suboptimal eye examination was found in 62% of patients with missed fracture and in 13% of those with timely diagnosis (P<0.001). Adjusted odds ratios for missed diagnosis in patients aged under 18 years versus patients aged 18 years and over was 9.3 (95% CI 2.4-35) and in patients with suboptimal versus sufficient eye examination 13.6 (95% CI 5.1-37). More common clinical manifestations in patients aged under 18 years were diplopia or restricted eye movements (P=0.005), pain in eye movements (P=0.010), nausea and/or vomiting (P<0.001), and bradycardia (P=0.014); periorbital haematoma was rarer (P<0.001). Suboptimal eye examination was involved in 62% and misinterpretation of computed tomography images in 50% of missed fractures, together explaining 85% of cases. CONCLUSIONS: Orbital blowout fractures are often missed in primary examination, especially in children and adolescents, who also present with subtler clinical manifestations. While the diagnosis can be difficult, appropriate clinical and radiological examination will reveal most cases.

RESUMEN

OBJECTIVE: To investigate whether individuals with an elevated BMI measurement, for whom a diagnosis of overweight or obesity (OW/OB) is not recorded, are less likely to be offered clinical care for obesity compared to those with a recorded diagnosis. SUBJECTS: A retrospective cohort study using the electronic medical record database of Maccabi Healthcare Services (MHS) in Israel. Included were 200,000 adults with BMI ≥ 25 kg/m2 measurement recorded during a primary care visit between 2014 and 2020, and no prior diagnosis of OW/OB or related co-morbidities. METHODS: The relationships between a recorded diagnosis of OW/OB and two composite outcomes: 1. A composite of referrals to screening tests for metabolic complications; 2. A composite of weight loss intervention and follow up, were analyzed using multivariate logistic regression models. RESULTS: In only 18% of individuals, a diagnosis of OW/OB was recorded. After adjusting for multiple potential confounding factors, individuals who received a recorded diagnosis were 18% more likely to be offered an evaluation for obesity-related metabolic complication, (OR 1.18, 95% CI 1.15-1.21, p < 0.001), and almost twice as likely to be offered intervention and follow up for their excess body weight (OR 1.84, 95% CI 1.76-1.94, p < 0.001) compared to individuals with missed diagnosis. These results persisted after adjusting for inter-physician variability. In addition, male sex, older age, and Arab sector were all associated with lower rates of weight loss intervention and follow up, while young individuals were less likely to be screened for metabolic complications. CONCLUSION: Beyond BMI measurement, a recorded diagnosis of OW/OB is associated with statistically and clinically significant higher rates of performance of obesity care and intervention. Undiagnosed OW/OB presents a significant clinical opportunity, as recording a diagnosis of OW/OB would predict improved patient access to obesity healthcare and improved clinical outcomes.
