CASE STUDY 95-04: Operator Certification: A Case Study in Operator Self-Inspection

Operator certification is the process where production workers are trained, authorized, and given the necessary resources to inspect their own work. This case study evaluated operator certification systems in the manufacturing process at three major aerospace companies during the Spring of 1995. Within the manufacturing area, operator certification was observed in such operations as high volume machining operations, certain processing operations-such as leak testing, balancing, and painting-and production of high volume detail parts. This case study was initiated as a result of the data from the human resources focus group’s survey in 1994. Prof. Jan Klein found that the airframe sector had a significantly lower percentage of plants where production workers perform inspection tasks as compared to the engine and electronics sectors. While operator certification is not a new concept, it appeared to be a best practice within two of the three sectors of the aerospace industry. This case study was performed to investigate these high potential payoffs

Lean Implementation Considerations in Factory Operations of Low Volume/High Complexity Production Systems

The researchers of the Lean Aircraft Initiative developed a hypothesized lean implementation model seeking to provide its members guidance on implementing lean transitions in factory operations of low volume/high complexity production systems. The model features four phases: (1) building a lean infrastructure to support lean behavior, (2) redesigning the flow of products in the factory, (3) revamping the operations management and (4) fostering process improvement. An order of implementation is discussed and each phase has implementation steps as well. Following the development of the hypothesized lean implementation model, twelve case studies were used to test the model. This report details the model and analyzes the case studies using the model as a framework

Development and preliminary results of an Electronic Medical Record (EMR)-integrated smartphone telemedicine program to deliver asthma care remotely

Background: Technology-based interventions that can function within real-world practice and improve outcomes without increasing provider burden are needed, yet few successfully cross the research-to-practice divide. This paper describes the process of developing a clinically-integrated smartphone-telemedicine program for adults with asthma and results from proof-of-concept testing. Methods: To ensure integration with practice, we used a contextually-grounded intervention development approach and May\u27s implementation theory to design the intervention, with emphasis on systems capabilities and stakeholder needs. The intervention incorporated symptom monitoring by smart phone, smartphone telemedicine visits and self-management training with a nurse, and clinical decision support software, which provided automated calculations of asthma severity, control, and step-wise therapy. Seven adults (aged 18-40) engaged in a 3-month beta-test. Asthma outcomes (control, quality of life, FEV1) and healthcare utilization patterns were measured at baseline and end-of-study. Results: Each participant received an average of 4 telemedicine visits with 94% patient satisfaction. All participants had uncontrolled asthma at baseline; by end-of-study 5/7 classified as well controlled. Mean asthma control improved 1.55 points (CI=0.59-2.51); quality of life improved 1.91 points CI=0.50-3.31), and FEV1 percent predicted increased 14.86% (CI=-3.09-32.80) with effect sizes of d=1.16, 1.09, and 0.96, respectively. Preventive healthcare utilization increased significantly (1.86 visits/year vs. 0.28/year prior, CI 0.67-2.47) as did prescriptions for controller medications (9.29 refills/year vs. 1.57 refills/year, CI 4.85-10.58) Conclusion: Smartphone telemedicine may be an effective means to improve outcomes and deliver asthma care remotely. However, careful attention to systems capabilities and stakeholder acceptability is needed to ensure successful integration with practice

A mixed‐methods analysis of younger adults\u27 perceptions of asthma, self‐management, and preventive care: This isn\u27t helping me none

Background: Young adults (ages 18‐44) have increased emergency department use for asthma and poor adherence to medications. The objective of this mixed‐methods study was to understand experiences with and approaches to managing asthma, of which little is known in this age group. Methods: Surveys (Asthma Control Questionnaire, Asthma Quality of Life Questionnaire) and 1:1 semi‐structured interviews were used to explore experiences with asthma, symptoms, self‐management behaviors, and relationship to asthma control and quality of life. Qualitative data were analyzed using content analysis techniques. Descriptive statistics and bivariate correlations were used to examine distributive characteristics and associations between variables. Results: Forty urban adults participated (mean age 32.7 ± 6.2, 1σ). Coughing was reported nearly 46% more often than wheezing, with 42.5% (17/40) coughing until the point of vomiting most days. Most participants delayed using medication for symptoms due to misperceptions about inhalers. Higher symptom frequency and worse asthma control were associated with greater use of non‐pharmacologic symptom management strategies (r=0.645, p\u3c0.001; r=0.360, p=0.022, respectively). Five themes were identified regarding young adults experiences with asthma: (1) having asthma means being limited and missing out on life; (2) healthcare for asthma is burdensome and other things are more important; (3) there is not enough personal benefit in medical interactions to make preventive care worthwhile; (4) there is insufficient support and education about asthma for adults; and (5) people normalize chronic symptoms over time and find ways of coping that fit with their lifestyle. Conclusions & Clinical Relevance: Young adults may tolerate symptoms without using quick‐relief medication or seeking preventive care. Increasing engagement with preventive services will require decreasing perceived burdens and increasing the personal benefits of care. Evaluating for non‐pharmacologic approaches to managing symptoms and asthma‐related coughing may identify uncontrolled asthma. Enhanced training for clinicians in patient‐centric asthma care may be needed

Going Mobile with Primary Care: Smartphone-Telemedicine for Asthma Management in Young Urban Adults (TEAMS)

Background: The majority of adults with persistent asthma have chronically uncontrolled disease and interventions to improve outcomes are needed. We evaluated the efficacy, feasi- bility, and acceptability of a multi-component smartphone-telemedicine program (TEAMS) to deliver asthma care remotely, support provider adherence to asthma management guide- lines, and improve patient outcomes. Methods: TEAMS utilized: (1) remote symptom monitoring, (2) nurse-led smartphone-tele- medicine with self-management training for patients, and (3) Electronic medical record- based clinical decision support software. Adults aged 18-44 (N=33) and primary care providers (N=4) were recruited from a safety-net practice in Upstate New York. Asthma con- trol, quality of life, and FEV1 were measured at 0, 3 and 6 months. Acceptability was assessed via survey and end-of-study interviews. Paired t-test and mixed effects modeling were used to evaluate the effect of the intervention on asthma outcomes. Results: At baseline, 80% of participants had uncontrolled asthma. By 6-months, 80% classi- fied as well-controlled. Improvements in control and quality of life were large (d=1.955, d=1.579). FEV%pred increased 4.2% (d=1.687) with the greatest gain in males, smokers, and lower educational status. Provider adherence to national guidelines increased from 43.3% to 86.7% (CI = 22.11-64.55) and patient adherence to medication increased from 45.58% to 85.29% (CI = 14.79-64.62). Acceptability was 95.7%; In follow up interviews, 29/30 patients and all providers indicated TEAMS worked better than usual care, supported effective self- management, and reduced symptoms over time, which led to greater self-efficacy and motivation to manage asthma. Discussion: Based on these findings, we conclude that smartphone telemedicine could substantially improve clinical asthma management, adherence to guidelines, and patient outcomes

An audio personal health library of clinic visit recordings for patients and their caregivers (HealthPAL): User-centered design approach

Background: Providing digital recordings of clinic visits to patients has emerged as a strategy to promote patient and family engagement in care. With advances in natural language processing, an opportunity exists to maximize the value of visit recordings for patients by automatically tagging key visit information (eg, medications, tests, and imaging) and linkages to trustworthy web-based resources curated in an audio-based personal health library. Objective: This study aims to report on the user-centered development of HealthPAL, an audio personal health library. Methods: Our user-centered design and usability evaluation approach incorporated iterative rounds of video-recorded sessions from 2016 to 2019. We recruited participants from a range of community settings to represent older patient and caregiver perspectives. In the first round, we used paper prototypes and focused on feature envisionment. We moved to low-fidelity and high-fidelity versions of the HealthPAL in later rounds, which focused on functionality and use; all sessions included a debriefing interview. Participants listened to a deidentified, standardized primary care visit recording before completing a series of tasks (eg, finding where a medication was discussed in the recording). In the final round, we recorded the patients\u27 primary care clinic visits for use in the session. Findings from each round informed the agile software development process. Task completion and critical incidents were recorded in each round, and the System Usability Scale was completed by participants using the digital prototype in later rounds. Results: We completed 5 rounds of usability sessions with 40 participants, of whom 25 (63%) were women with a median age of 68 years (range 23-89). Feedback from sessions resulted in color-coding and highlighting of information tags, a more prominent play button, clearer structure to move between one\u27s own recordings and others\u27 recordings, the ability to filter recording content by the topic discussed and descriptions, 10-second forward and rewind controls, and a help link and search bar. Perceived usability increased over the rounds, with a median System Usability Scale of 78.2 (range 20-100) in the final round. Participants were overwhelmingly positive about the concept of accessing a curated audio recording of a clinic visit. Some participants reported concerns about privacy and the computer-based skills necessary to access recordings. Conclusions: To our knowledge, HealthPAL is the first patient-centered app designed to allow patients and their caregivers to access easy-to-navigate recordings of clinic visits, with key concepts tagged and hyperlinks to further information provided. The HealthPAL user interface has been rigorously co-designed with older adult patients and their caregivers and is now ready for further field testing. The successful development and use of HealthPAL may help improve the ability of patients to manage their own care, especially older adult patients who have to navigate complex treatment plans
