Retention of En Route Cricothyroidotomy Skills in Novice Providers Following a Simulation-Based Mastery Learning Curriculum.

INTRODUCTION: Surgical cricothyroidotomy (SC) is a vital skill that combat first responders must master as airway obstruction is the third most preventable cause of death on the battlefield. Degradation of skills over time is a known problem, and there is inadequate knowledge regarding the rate of SC skill retention. Our prior study showed that simulation-based mastery learning was effective in training 89 novices how to reliably perform an en route SC to mastery performance standards. This study aims to assess the durability of this skill by bringing participants back in 3 separate cohorts at 6, 12, or 24 months following the initial training to perform SC in the same test environment. MATERIALS AND METHODS: This was a randomized prospective trial. Random cohorts of equal subjects who previously underwent SC simulation-based mastery learning training were selected to return at 6, 12, and 24 months to retest in the same en route medical evacuation (MEDEVAC) helicopter scenario. A total of 22, 14, and 10 subjects returned at 6, 12, and 24 months, respectively, due to Coronavirus-19 impacts and travel limitations. Participants in the 24-month cohort received a refresher training prior to retesting. All attempts were recorded and blindly graded using the same 10 item standardized SC checklist used in initial training. Our previous work found that mastery criteria for performing a SC were ≤40 seconds and completion of 9/10 items on the checklist. Outcome measures in this study were time to complete the procedure and percent of subjects who completed at least 9/10 items on the SC checklist. RESULTS: There was an increase in time required to complete the procedure compared to initial training in all three retesting cohorts (initial: median 27.50, interquartile range 25.38-31.07 seconds; 6 months: median 36.33, interquartile range 31.59-55.22 seconds; 12 months: median 49.50, interquartile range 41.75-60.75 seconds; 24 months: median 38.79, interquartile range 30.20-53.08 seconds; P < .0001, P < .0001, P = .0039). There was a decline in median value checklist scores compared to initial training in the 6- and 12-month retesting cohorts (initial: median 10.00/10, interquartile range 9.50-10.00; 6 months: median 8.00/10, interquartile range 6.75-9.00; 12 months: median 8.00/10, interquartile range 6.75-9.25; P < .0001, P < .001). There was no difference in median checklist scores between the initial and 24-month retesting scenario (initial: median 10.00/10, interquartile range 9.50-10.00; 24 months: 10.00/10, interquartile range 9.00-10.00; P= .125). There was a decrease in retention of skills as only 31.82% of subjects at 6 months and 14.29% at 12 months met the defined passing criteria of time to completion of ≤40 seconds and checklist score of ≥9/10. A brief refresher course several months prior to the 24-month cohort retesting greatly increased the retention of SC procedural skills, with 60% of subjects meeting the time and checklist criteria. CONCLUSIONS: This study showed that the skill required to perform a SC after initial mastery training does decay significantly. A brief refresher course can help increase retention of skills. Based on our findings SC skills should be refreshed at a minimum of every 6 months to assure optimal proficiency.

Development of a Simulation Surgical Cricothyroidotomy Curriculum for Novice Providers: A Learning Curve Study.

INTRODUCTION: Airway obstruction is the third most common cause of preventable death on the battlefield, accounting for 1%-2% of total combat fatalities. No previous surgical cricothyroidotomy (SC) studies have analyzed the learning curve required to obtain proficiency despite being studied in numerous other surgical technique training experiments. The aims of this study were to establish expert SC performance criteria, develop a novel standardized SC curriculum, and determine the necessary number of practice iterations required by a novice to reach this pre-determined performance goal. MATERIALS AND METHODS: A standardized checklist and SC performance standards were established based on the performance of 12 board certified Military Health System surgeons with prior experience on performing a SC using a simulated trauma mannequin. Expert-level criteria were defined as a SC time to completion of 40 s or less and checklist score of at least 9/10, including all critical steps. Study subjects included 89 novice providers (54 active-duty first- and second-year medical students and 35 Navy corpsmen). Subjects received instruction on performing a SC using the principles of mastery learning and performed a final test of SC proficiency on a trauma mannequin within a realistic simulated MEDEVAC helicopter. The total number of subject practice attempts, checklist scores, and time to completion were measured and/or blindly scored. Learning curve and exponential plateau equations were used to characterize their improvement in mean time to SC completion and checklist scores. RESULTS: Mean pre-test knowledge scores for the entire group were 11.8 ± 3.1 out of 24 points. Total mean practice learning plateaued at checklist scores of 9.9/10 after 7 iterations and at a mean completion time of 30.4 s after 10 iterations. During the final test performance in the helicopter, 67.4% of subjects achieved expert-level performance on the first attempt. All subjects achieved expert-level performance by the end of two additional attempts. While a significantly larger proportion of medical students (79.9%) successfully completed the helicopter test on the first attempt compared to corpsmen (54.3%), there were no statistically significant differences in mean SC completion times and checklist scores between both groups (P > 0.05). Medical students performed a SC only 1.3 s faster and scored only 0.16 points higher than corpsmen. The effect size for differences were small to negligible (Cohen's d range 0.18-0.33 for SC completion time; Cohen's d range 0.45-0.46 for checklist scores). CONCLUSION: This study successfully defined SC checklist scores and completion times based on the performance of experienced surgeons on a simulator. Using these criteria and the principles of mastery learning, novices with little knowledge and experience in SC were successfully trained to the level of experienced providers. All subjects met performance targets after training and overall performance plateaued after approximately seven iterations. Over two-thirds of subjects achieved the performance target on the first testing attempt in a simulated helicopter environment. Performance was comparable between medical student and corpsmen subgroups. Further research will assess the durability of maintaining SC skills and the timing for introducing refresher courses after initial skill acquisition.

"Pull yourself up by your bootstraps": a response to depression in older adults.

Although depression is one of the most common problems among adults in primary care settings, many do not seek or adhere to the treatment regimens suggested by their providers. Understanding the cultural model surrounding depression and its treatment in older adults might provide insight into the development of more effective strategies for addressing the problem in the clinical setting. In this study, the authors conducted semi-structured interviews with adults over age 65. Personal responsibility for the management of depression emerged as a pervasive approach to dealing with depression. Older adults used orientational and movement metaphors to describe the process of moving out of depression. They viewed initiation and follow-through of this process as the sole responsibility of the depressed individual. This attitude might be rooted in the cultural experiences of this particular cohort of older adults and has implications for their use of physical and mental health services for depression.

Clinic-based treatment for opioid dependence: a qualitative inquiry.

OBJECTIVES: To identify barriers and facilitators to treatment of opioid dependence in primary care clinics. METHODS: In-depth interviews with 27 New York State clinic directors. RESULTS: Stigmatizing attitudes emerged as a major barrier. Respondents often viewed opioid-dependent persons as manipulative, demanding, and disruptive. Commonly cited facilitators were physician training, increased office staffing, and greater mental health, social services, and addictions support. CONCLUSIONS: Our study reveals attitudinal barriers to address and supportive factors to promote in order to increase the limited availability of office-based treatment of opioid dependence in the United States compared with other countries.

'Breaking it down': patient-clinician communication and prenatal care among African American women of low and higher literacy.

PURPOSE: Low literacy has been associated with poor medical adherence, but its role in maternal care utilization has not been explored. METHODS: We undertook a concurrent mixed methods study among 202 African American women of low (< or = 6th grade) and higher literacy receiving Medicaid. Poor use of prenatal care was defined by (1) starting care after the first trimester and (2) inadequate care utilization according to the Adequacy of Prenatal Care Utilization Index (APNCU). Participant-derived themes regarding prenatal care and care utilization were identified and explored through individual interviews (free listing and cultural consensus analysis; n = 40), and 4 confirmatory focus groups stratified by literacy. RESULTS: Thirty-three women (16%) had low-literacy levels, 120 (61%) women started prenatal care after the first trimester, and 101 (50%) had inadequate utilization of prenatal care. Neither measure varied by literacy (P >.05). Cultural consensus analysis identified a single prenatal care factor that was comprised of 9 items, shared by women of low and higher literacy (eigenvalue 0.881, SD 0.058). Focus groups confirmed these items among participants from both literacy groups. Communication with clinicians was a central theme linking all of the factor items. Effective communication, exemplified by "breaking it down," was described as encouraging, whereas ineffective communication discouraged use of care. CONCLUSION: Women who had both low- and higher-literacy skills had high rates of poor prenatal care utilization and reported that communication with clinicians influenced their use of prenatal care. Improving the clarity of communication by breaking down information into simple parts should be a priority for prenatal clinicians.
