RESUMEN

The diagnosis of lung cancer in ambulatory settings is often challenging due to non-specific clinical presentation, but there are currently no clinical quality measures (CQMs) in the United States used to identify areas for practice improvement in diagnosis. We describe the pre-diagnostic time intervals among a retrospective cohort of 711 patients identified with primary lung cancer from 2012-2019 from ambulatory care clinics in Seattle, Washington USA. Electronic health record data were extracted for two years prior to diagnosis, and Natural Language Processing (NLP) applied to identify symptoms/signs from free text clinical fields. Time points were defined for initial symptomatic presentation, chest imaging, specialist consultation, diagnostic confirmation, and treatment initiation. Median and interquartile ranges (IQR) were calculated for intervals spanning these time points. The mean age of the cohort was 67.3 years, 54.1% had Stage III or IV disease and the majority were diagnosed after clinical presentation (94.5%) rather than screening (5.5%). Median intervals from first recorded symptoms/signs to diagnosis was 570 days (IQR 273-691), from chest CT or chest X-ray imaging to diagnosis 43 days (IQR 11-240), specialist consultation to diagnosis 72 days (IQR 13-456), and from diagnosis to treatment initiation 7 days (IQR 0-36). Symptoms/signs associated with lung cancer can be identified over a year prior to diagnosis using NLP, highlighting the need for CQMs to improve timeliness of diagnosis.

RESUMEN

Background: Usability - the extent to which an intervention can be used by specified users to achieve specified goals with effectiveness, efficiency, and satisfaction - may be a key determinant of implementation success. However, few instruments have been developed to measure the design quality of complex health interventions (i.e., those with several interacting components). This study evaluated the structural validity of the Intervention Usability Scale (IUS), an adapted version of the well-established System Usability Scale (SUS) for digital technologies, to measure the usability of a leading complex psychosocial intervention, Motivational Interviewing (MI), for behavioral health service delivery in primary care. Prior SUS studies have found both one- and two-factor solutions, both of which were examined in the current study of the IUS. Method: A survey administered to 136 medical professionals from 11 primary care sites collected demographic information and IUS ratings for MI, the evidence-based psychosocial intervention that primary care providers reported using most often for behavioral health service delivery. Factor analyses replicated procedures used in prior research on the SUS. Results: Analyses indicated that a two-factor solution (with "usable" and "learnable" subscales) best fit the data, accounting for 54.1% of the variance. Inter-item reliabilities for the total score, usable subscale, and learnable subscale were α = .83, α = .84, and α = .67, respectively. Conclusions: This study provides evidence for a two-factor IUS structure consistent with some prior research, as well as acceptable reliability. Implications for implementation research evaluating the usability of complex health interventions are discussed, including the potential for future comparisons across multiple interventions and provider types, as well as the use of the IUS to evaluate the relationship between usability and implementation outcomes such as feasibility.

RESUMEN

BACKGROUND AND OBJECTIVES: Interest in global health (GH) has increased significantly among medical trainees in the past 3 decades. Despite the potential for family medicine to be a major contributor to GH, there are no recent, large-scale studies of GH education and experiences in family medicine training. This study was designed to assess current opportunities, educational activities, resident interest, perceived program benefits, and barriers to international and domestic GH training in US family medicine residencies. METHODS: Data for this study were elicited as part of a 2015 survey conducted by the Council of Academic Family Medicine (CAFM) Educational Research Alliance (CERA). The nationwide, web-based survey was sent to 452 family medicine residency program directors. RESULTS: A total of 257 program directors completed the GH portion of the survey. A total of 74.3% of programs offered international or domestic GH experiences. Program directors identified preparing physicians to practice underserved medicine and teaching community medicine or public health as primary goals for GH training. Program directors also reported that GH opportunities were important for attracting future residents. Programs offered a variety of preparatory activities to their residents. Funding and time constraints were identified as the primary barriers to GH training in residency. CONCLUSIONS: Global health continues to be a focus of interest in the training of family medicine residents while attracting the passion of student applicants and residents.

RESUMEN

BACKGROUND: Bacteria in the Pantoea genus are plant and soil associated Gram-negative rods described as nosocomial pathogens and as rare causes of community-acquired infections. The latter have been classically associated with gardening and plant thorn injuries and immunocompromised states are additional risk factors. We report a patient with pica and geophagia, Pantoea sepsis, and sickle cell crisis, associations not previously described. CASE REPORT: A 23-year-old pregnant female presented to the emergency department with sickle cell pain crisis. On the third day of hospitalization the patient developed fever subsequently determined to be caused by Pantoea bacteremia and sepsis. She was successfully treated with a two-week course of ceftriaxone. The patient admitted to a habit of frequently eating large amounts of soil and this geophagia had increased since she became pregnant. She had marked clinical improvement with treatment and she was counseled to stop eating soil. CONCLUSIONS: This is the first reported case of Pantoea infection possibly associated with geophagia and the first reported case of Pantoea bacteremia and sepsis related to an episode of sickle cell crisis.
