Human Factors Contributing to Infection Prevention in Outpatient Hemodialysis Centers: A Mixed Methods Study.

RATIONALE & OBJECTIVE: Infection prevention efforts in dialysis centers can avert patient morbidity and mortality but are challenging to implement. The objective of this study was to better understand how the design of the work system might contribute to infection prevention in outpatient dialysis centers. STUDY DESIGN: Mixed methods, observational study. SETTING & PARTICIPANTS: Six dialysis facilities across the United States visited by a multidisciplinary team over 8 months. ANALYTICAL APPROACH: At each facility, structured macroergonomic observations were undertaken by a multidisciplinary team using the SEIPS 1.0 model. Ethnographic observations were collected about staff encounters with dialysis patients including the content of staff conversations. Selective and axial coding were used for qualitative analysis and quantitative data were reported using descriptive statistics. RESULTS: Organizational and sociotechnical barriers and facilitators to infection prevention in the outpatient dialysis setting were identified. Features related to human performance, (eg, alarms, interruptions, and task stacking), work system design (eg, physical space, scheduling, leadership, and culture), and extrinsic factors (eg, patient-related characteristics) were identified. LIMITATIONS: This was an exploratory evaluation with a small sample size. CONCLUSIONS: This study used a systematic macroergonomic approach in multiple outpatient dialysis facilities to identify infection prevention barriers and facilitators related to human performance. Several features common across facilities were identified that may influence infection prevention in outpatient care and warrant further exploration.

Implementing Root Cause Analysis and Action: Integrating Human Factors to Create Strong Interventions and Reduce Risk of Patient Harm.

OBJECTIVES: The goal of this study was to develop a systems approach for root cause analysis and action to achieve strong, sustainable interventions. The team integrated human factors principles into the design of interventions to ensure solutions maintain compatibility with human capabilities and limitations resulting in stronger solutions to prevent reoccurrence. METHODS: This study was conducted at a 7-hospital health system located in southwestern Virginia. Including human factors in a new root cause analysis and action process allowed the team to design strong interventions. To assess the results of this process, a team evaluated all interventions over a 4-year period (2.75-y preimplementation and 1.4-y postimplementation). Interventions were initially blind coded and then consensus coding was executed to finalize the strength of each intervention according to the VA National Center for Patient Safety evaluation tool. RESULTS: The new process resulted in an efficient method to address adverse events with increased staff satisfaction and interventions more resilient to human error. The number of events with strong interventions increased from 43% to 69% after implementation of the new process. CONCLUSIONS: Tailoring an event investigation process to an organizational culture is critical to implementation success. Adding human factors into the design of interventions helped facilitate intervention implementation and sustainability. Blinded ratings showed that with the integration of human factors, there was improved strength of interventions. This indicates that a focus on strong system improvement (rather than weaker individual human-based solutions) will lead to improved staff satisfaction and patient safety.

Risk of RBC alloimmunization in multiple myeloma patients treated by Daratumumab.

BACKGROUND: Daratumumab (DARA) is a human monoclonal antibody for the treatment of multiple myeloma (MM). DARA binds to CD38 on RBCs and interferes with detection of RBC alloantibodies. The objective of this study was to evaluate the risk of RBC alloimmunization in MM patients treated with DARA. MATERIALS AND METHODS: A retrospective study of the complete serological profile and transfusion history of 45 MM patients received transfusion and treated with DARA from July 2015 to December 2018 was undertaken. All cases with positive Ab screens were treated with DTT to identify RBC alloantibodies. RBC transfusion history was monitored between the first DARA dose to the last or extending to the first negative Ab screen after the last DARA dose if the Ab screen was ever positive. Forty-six MM patients received transfusion but not DARA were studied as control group. RESULTS: Totally 184 Ab screens were done on 45 patients transfused with ABO-Rh compatible RBCs, phenotypically matched units or both. None of them showed detectable alloantibodies after DTT treatment. The duration of Ab screening positivity varied markedly, ranging from 25 days to 5 months after the last dose. Two of 46 patients in the control group had preexisting alloantibodies but no new alloantibodies were detected during study period. CONCLUSIONS: Our results indicate that the risk of forming new RBC alloantibodies after transfusion in MM patients treated with current regimens is very low and no DARA-associated difference in the alloimmunization risk. No significant difference in alloimmunization is detected between ABO-Rh compatible and phenotypically matched transfusion.

Correction to: Patient perceptions of acute pain and activity disruption following inguinal hernia repair: a propensity-matched comparison of robotic-assisted, laparoscopic, and open approaches.

Unfortunately, the online published article has errors in Table 2. The number "118.0" found under the column "L-IHR" and row "Time from IHR to resume activities" should be corrected to 18.0.

Patient perceptions of acute pain and activity disruption following inguinal hernia repair: a propensity-matched comparison of robotic-assisted, laparoscopic, and open approaches.

Few publications describe the potential benefit of robotic-assisted inguinal hernia repair on acute postoperative groin pain (APGP). This study compared patients' perceptions of APGP, activity limitation, and overall satisfaction after robotic-assisted- (R), laparoscopic (L), or open (O) inguinal hernia repair (IHR). Random samples of patients from two web-based research panels and surgical practices were screened for patients who underwent IHR between October 28, 2015 and November 1, 2016. Qualified patients were surveyed to assess perceived APGP at 1 week postoperatively, activity disruption, and overall satisfaction. Three cohorts based on operative approach were compared after propensity matching. Propensity scoring resulted in 83 R-IHR matched to 83 L-IHR respondents, while 85 R-IHR matched with 85 O-IHR respondents. R-IHR respondents recalled less APGP compared to respondents who had O-IHR (4.1 ± 0.3 vs 5.6 ± 0.3, p < 0.01) but similar APGP compared to L-IHR (4.0 ± 0.3 vs 4.4 ± 0.3, p = 0.37). Respondents recalled less activity disruption 1 week postoperatively after R-IHR versus O-IHR (6.1 ± 0.3 vs. 7.3 ± 0.2, p < 0.01) but similar levels of activity disruption after R-IHR and L-IHR (6.0 ± 0.3 vs. 6.6 ± 0.27, p = 0.32). At the time of the survey, respondents perceived less physical activity disruption after R-IHR compared to O-IHR (1.4 ± 0.2 vs. 2.8 ± 0.4, p < 0.01) but similar between R-IHR and L-IHR (1.3 ± 0.2 vs 1.2 ± 0.2, p = 0.94). Most respondents felt satisfied with their outcome regardless of operative approach. Patient perceptions of pain and activity disruption differ by approach, suggesting a potential advantage of a minimally invasive technique over open for IHR. Further studies are warranted to determine long-term outcomes regarding pain and quality of life after IHR.

Evaluation of Sensor Technology to Detect Fall Risk and Prevent Falls in Acute Care.

BACKGROUND: Sensor technology that dynamically identifies hospitalized patients' fall risk and detects and alerts nurses of high-risk patients' early exits out of bed has potential for reducing fall rates and preventing patient harm. During Phase 1 (August 2014-January 2015) of a previously reported performance improvement project, an innovative depth sensor was evaluated on two inpatient medical units to study fall characteristics. In Phase 2 (April 2015-January 2016), a combined depth and bed sensor system designed to assign patient fall probability, detect patient bed exits, and subsequently prevent falls was evaluated. METHODS: Fall detection depth sensors remained in place on two medicine units; bed sensors used to detect patient bed exits were added on only one of the medicine units. Fall rates and fall with injury rates were evaluated on both units. RESULTS: During Phase 2, the designated evaluation unit had 14 falls, for a fall rate of 2.22 per 1,000 patient-days-a 54.1% reduction compared with the Phase 1 fall rate. The difference in rates from Phase 1 to Phase 2 was statistically significant (z = 2.20; p = 0.0297). The comparison medicine unit had 30 falls-a fall rate of 4.69 per 1,000 patient-days, representing a 57.9% increase as compared with Phase 1. CONCLUSION: A fall detection sensor system affords a level of surveillance that standard fall alert systems do not have. Fall prevention remains a complex issue, but sensor technology is a viable fall prevention option.

Human factors engineering approaches to patient identification armband design.

The task of patient identification is performed many times each day by nurses and other members of the care team. Armbands are used for both direct verification and barcode scanning during patient identification. Armbands and information layout are critical to reducing patient identification errors and dangerous workarounds. We report the effort at two large, integrated healthcare systems that employed human factors engineering approaches to the information layout design of new patient identification armbands. The different methods used illustrate potential pathways to obtain standardized armbands across healthcare systems that incorporate human factors principles. By extension, how the designs have been adopted provides examples of how to incorporate human factors engineering into key clinical processes.

Firefighting to Innovation: Using Human Factors and Ergonomics to Tackle Slip, Trip, and Fall Risks in Hospitals.

OBJECTIVE: The aim of this study was to use a theoretical model (bench) for human factors and ergonomics (HFE) and a comparison with occupational slips, trips, and falls (STFs) risk management to discuss patient STF interventions (bedside). BACKGROUND: Risk factors for patient STFs have been identified and reported since the 1950s and are mostly unchanged in the 2010s. The prevailing clinical view has been that STF events indicate underlying frailty or illness, and so many of the interventions over the past 60 years have focused on assessing and treating physiological factors (dizziness, illness, vision/hearing, medicines) rather than designing interventions to reduce risk factors at the time of the STF. METHOD: Three case studies are used to discuss how HFE has been, or could be, applied to STF risk management as (a) a design-based (building) approach to embed safety into the built environment, (b) a staff- (and organization-) based approach, and (c) a patient behavior-based approach to explore and understand patient perspectives of STF events. RESULTS AND CONCLUSION: The results from the case studies suggest taking a similar HFE integration approach to other industries, that is, a sustainable design intervention for the person who experiences the STF event-the patient. APPLICATION: This paper offers a proactive problem-solving approach to reduce STFs by patients in acute hospitals. Authors of the three case studies use HFE principles (bench/book) to understand the complex systems for facility and equipment design and include the perspective of all stakeholders (bedside).

Crisis Counselors' Perceptions and Assessment of Suicidal Behavior Among Hurricane Survivors Receiving Crisis Counseling Services.

OBJECTIVE: The aims of this study were to assess the awareness of risk for suicidal behaviors and perspectives of Project Recovery counselors who provided crisis counseling services to hurricane survivors. METHODS: The Short Posttraumatic Stress Disorder Rating Interview-Extended, a quantitative disaster mental health measure, was used to assess distress and dysfunction to the recent hurricanes. Project Recovery counselor data were collected through a 22-item qualitative interview. RESULTS: Seven out of 207 clients (3.4%) endorsed the quantitative item measuring suicidal ideation. Clients who reported suicidal ideation had significantly higher scores on items indicating a loss of enjoyment, feelings of depression, feeling less able to handle stress, and other mental health items. Counselor responses fell into 5 major themes: Assessment and Action, Client Characteristics, Services, Counselor Training and Preparedness, and Future Directions. CONCLUSIONS: Suicidal behavior is a serious mental health emergency, yet it remains a challenging issue as suicidal behaviors are complex and disaster survivors with suicidal ideation may experience intense psychological reactions to the event. In order to provide competent care to survivors experiencing suicidal thoughts or behaviors, the need for counselors to receive adequate training in suicide assessment and management is essential.

The within-day relation between lonely episodes and subsequent clinical pain in individuals with fibromyalgia: Mediating role of pain cognitions.

OBJECTIVE: This daily diary study of individuals with fibromyalgia (FM) examined whether morning increases in loneliness relate to worsened evening bodily pain through afternoon negative pain cognitions. METHODS: 220 participants with FM completed electronic diaries 4 times a day for 21days to assess loneliness, negative pain cognitions, bodily pain, and social enjoyment. Multilevel structural equation modeling was used to examine within-person relations of morning increases in loneliness, afternoon negative pain cognitions, and evening pain, controlling for morning pain. RESULTS: On mornings when individuals experienced higher than their usual levels of loneliness, they experienced higher levels of afternoon maladaptive pain cognitions, which in turn predicted increases in evening pain above the level of morning pain. Afternoon maladaptive pain cognitions fully mediated the relations between morning loneliness and evening pain. CONCLUSIONS: Lonely episodes are associated with subsequent increases in negative patterns of thinking about pain, which in turn predict subsequent increases in bodily pain within a day. Because pain cognitions mediate the loneliness-pain link, FM interventions may benefit from addressing individuals' vulnerability to maladaptive cognitions following lonely episodes.

Quality of life in psychogenic nonepileptic seizures and epilepsy: the role of somatization and alexithymia.

It is clear that many individuals with psychogenic nonepileptic seizures (PNESs) often present with poorer quality of life compared with those with epileptic seizures (ESs). However, the mechanisms linking seizure diagnosis to quality-of-life outcomes are much less clear. Alexithymia and somatization are emotional markers of psychological functioning that may explain these differences in quality of life. In the current study, patients from an epilepsy monitoring unit with vEEG-confirmed diagnosis of PNESs or ESs were compared on measures of alexithymia, somatization, quality of life, and a variety of demographic and medical variables. Two models using alexithymia and somatization individually as mediators of the relations between diagnosis and quality of life were tested. Results indicated that patients with PNESs had significantly poorer quality of life compared with those with ESs. Alexithymia was associated with poor quality of life in both groups but did not differentiate between diagnostic groups. Further, alexithymia did not mediate the relationship between diagnosis and quality of life. Somatization was associated with poor quality of life, and patients with PNESs reported greater somatization compared with patients with ESs. Somatization also significantly mediated the relationship between diagnosis and quality of life. In conclusion, somatization may be one mechanism affecting poor quality of life among patients with PNESs compared with ESs and should be a target of comprehensive treatments for PNESs. Alexithymia proved to be an important factor impacting quality of life in both groups and should also be targeted in treatment for patients with PNESs and patients with ESs.

Mindfulness and cognitive-behavioral interventions for chronic pain: differential effects on daily pain reactivity and stress reactivity.

OBJECTIVE: This study compared the impact of cognitive-behavioral therapy for pain (CBT-P), mindful awareness and acceptance treatment (M), and arthritis education (E) on day-to-day pain- and stress-related changes in cognitions, symptoms, and affect among adults with rheumatoid arthritis (RA). METHOD: One hundred forty-three RA patients were randomized to 1 of the 3 treatment conditions. CBT-P targeted pain-coping skills; M targeted awareness and acceptance of current experience to enhance coping with a range of aversive experiences; E provided information regarding RA pain and its management. At pre- and posttreatment, participants completed 30 consecutive evening diaries assessing that day's pain, fatigue, pain-related catastrophizing and perceived control, morning disability, and serene and anxious affects. RESULTS: Multilevel models compared groups in the magnitude of within-person change in daily pain and stress reactivity from pre- to posttreatment. M yielded greater reductions than did CBT-P and E in daily pain-related catastrophizing, morning disability, and fatigue and greater reductions in daily stress-related anxious affect. CBT-P yielded less pronounced declines in daily pain-related perceived control than did M and E. CONCLUSIONS: For individuals with RA, M produces the broadest improvements in daily pain and stress reactivity relative to CBT-P and E. These findings also highlight the utility of a diary-based approach to evaluating the treatment-related changes in responses to daily life.

Loneliness, daily pain, and perceptions of interpersonal events in adults with fibromyalgia.

OBJECTIVE: This study examined whether individual differences in loneliness and/or daily exacerbations in loneliness relate to daily pain and frequency and perception of interpersonal events among individuals with fibromyalgia (FM). METHOD: In total, 118 participants with FM completed electronic diaries each evening for 21 days to assess the occurrence of positive and negative interpersonal events, event appraisals, and pain. Multilevel modeling was used to examine relations of chronic and transitory loneliness to daily life outcomes, controlling for daily depressive symptoms. RESULTS: Chronic and transitory loneliness were associated with more frequent reports of negative and less frequent reports of positive interpersonal daily events, higher daily stress ratings and lower daily enjoyment ratings, and higher daily pain levels. Neither chronic nor transitory loneliness moderated the relations between daily negative events and either stress appraisals or pain. However, both chronic and transitory loneliness moderated the relation between daily positive events and enjoyment appraisals. Specifically, on days of greater numbers of positive events than usual, lonely people had larger boosts in enjoyment than did nonlonely people. Similarly, days with greater than usual numbers of positive events were related to larger boosts in enjoyment if an individual was also experiencing higher than usual loneliness levels. CONCLUSIONS: Chronic and transient episodes of loneliness are associated with more negative daily social relations and pain. However, boosts in positive events yield greater boosts in day-to-day enjoyment of social relations for lonely versus nonlonely individuals, and during loneliness episodes, a finding that can inform future interventions for individuals with chronic pain.

Slip, trip, and fall injuries among nursing care facility workers.

The objective of this research was to describe the slip, trip, and fall injury experience and trends in a population of nursing home workers, identify risk factors for slip, trip, and fall injuries, and develop prevention strategies for slip, trip, and fall hazards. Workers' compensation injury claims data and payroll data from 1996 through 2003 were obtained from six nursing homes and used to calculate injury incidence rates. Narrative information was used to describe details of slip, trip, and fall events. A total of 86 slip, trip, and fall-related workers' compensation claims were filed during the 8-year period. Slip, trip, and fall claim rates showed a nonsignificant increase during the 8-year period. Most slips, trips, and falls were attributed to hazards that can be mitigated (e.g., water on the floor or loose cords in a walkway). Nursing home workers experience more slip, trip, and fall-related injury claims than workers in other industries. Preventive programs should be implemented and evaluated in this industry.

Fall prevention for inpatient oncology using lean and rapid improvement event techniques.

OBJECTIVE: The objective of this project was to reduce patient falls and falls with injury on three oncology divisions at a large urban teaching hospital. By standardizing assessment, intervention, and post-fall investigation processes the goal was to decrease patient falls and falls with injury rate by 50% and 30%, respectively. BACKGROUND: Preventing patients from being injured due to a fall during their hospitalization has been a concern in healthcare for many years. Organizations around the world such as Institute of Medicine, The Joint Commission, National Institute for Health and Clinical Excellence, National Australian Patient Safety Foundation, and the World Health Organization have been conducting research and publishing guidelines to identify evidence based interventions for fall prevention (Ulrich et al., 2008, Di Pilla, 2010). Falls are the most common cause of non-fatal injury and hospital admission for trauma. Death rates due to falls have risen sharply over the past decade due to aging of the population. METHODS: A Rapid Improvement Event (RIE) technique was selected to implement the fall prevention initiative because it aligned with the hospital's lean transformation initiative. There was coordination with other departmental staff (physical and occupational therapy, pharmacy, physicians, information systems, low bed equipment vendor, and clinical operations) to achieve multidisciplinary input. RESULTS: A 22% decrease in total fall rate and a 37% decrease in falls with injury rate were achieved in the 16-month post-intervention period. Although a 22% decrease in total falls did not meet the goal of 50% decrease, the total falls with injury decrease of 37% did exceed the goal of 30%. CONCLUSIONS: Falls are a multi-faceted, complex problem that needs constant vigilance and continuous improvement to sustain patient safety. Anticipating physiologic changes in patients' conditions and implementing interventions before the fall is critical to fall prevention. While well-validated screening tools performed thoroughly and accurately can help hospital staff identify patient specific fall risk factors, risk assessment alone does not prevent falls. If the prevention of patient falls is identified as important by leadership and staff at the division level and all are invested in achieving established goals, success can be achieved and sustained. KEYWORDS: Case study, falls, hospital, human factors, organizational transformation, patients.

Evaluation of a comprehensive slip, trip and fall prevention programme for hospital employees.

In 2007, the Bureau of Labor Statistics reported that the incidence rate of lost workday injuries from slips, trips and falls (STFs) on the same level in hospitals was 35.2 per 10,000 full-time equivalents (FTE), which was 75% greater than the average rate for all other private industries combined (20.2 per 10,000 FTEs). The objectives of this 10-year (1996-2005) longitudinal study were to: 1) describe occupational STF injury events in hospitals; 2) evaluate the effectiveness of a comprehensive programme for reducing STF incidents among hospital employees. The comprehensive prevention programme included analysis of injury records to identify common causes of STFs, on-site hazard assessments, changes to housekeeping procedures and products, introduction of STF preventive products and procedures, general awareness campaigns, programmes for external ice and snow removal, flooring changes and slip-resistant footwear for certain employee subgroups. The hospitals' total STF workers' compensation claims rate declined by 58% from the pre-intervention (1996-1999) rate of 1.66 claims per 100 FTE to the post-intervention (2003-2005) time period rate of 0.76 claims per 100 FTE (adjusted rate ratio = 0.42, 95% CI: 0.33-0.54). STFs due to liquid contamination (water, fluid, slippery, greasy and slick spots) were the most common cause (24%) of STF claims for the entire study period 1996-2005. Food services, transport/emergency medical service and housekeeping staff were at highest risk of a STF claim in the hospital environment. Nursing and office administrative staff generated the largest numbers of STF claims. STF injury events in hospitals have a myriad of causes and the work conditions in hospitals are diverse. This research provides evidence that implementation of a broad-scale prevention programme can significantly reduce STF injury claims.

Describing nurses' work: combining quantitative and qualitative analysis.

OBJECTIVE: To better understand nursing activities and working conditions. BACKGROUND: Nursing practice involves astute clinical decision making and the competent delivery of nursing care procedures. To complete nursing procedures, nurses must simultaneously organize and reorganize priorities and manage changing clinical information for multiple patients. Few researchers have examined the specific nature of nurses' activities and the effect of the environment on their work. METHODS: Quantitative and qualitative methods were used to collect data on 7 nurses engaged in nursing activities. Examples of methods include link analysis, subject matter expert, task analysis, cognitive pathway, and "stacking." Data collection focused on how nurses managed priorities, changing clinical information, and interruptions. RESULTS: The "cognitive pathway" graphically depicts the nature of nurses' work. Specifically, it reveals the shifting of the nurse's attention from patient to patient and the occurrence of interruptions. "Stacking" shows the number of tasks a nurse must balance at any one time. On average, nurses had 10 or more activities waiting to be performed and experienced 3.4 interruptions/hr. CONCLUSION: These methods provide unique insight into the dynamic nature of patient care and nursing work. APPLICATION: Extension of the methods demonstrated here may be useful in guiding efforts to change the work of nursing to better provide quality care and less stressful work environments.
