Patient Safety Culture and the Ability to Improve: A Proof of Concept Study on Hand Hygiene

OBJECTIVE: To investigate whether the safety culture of a hospital unit is associated with the ability to improve. DESIGN: Qualitative investigation of safety culture on hospital units following a before-and-after trial on hand hygiene. SETTING: VU University Medical Center, a tertiary-care hospital in the Netherlands. METHODS: With support from hospital management, we implemented a hospital-wide program to improve compliance. Over 2 years, compliance was measured through direct observation, twice before, and 4 times after interventions. We analyzed changes in compliance from baseline, and selected units to evaluate safety culture using a positive deviance approach: the hospital unit with the highest hand hygiene compliance and 2 units that showed significant improvement (21% and 16%, respectively) were selected as high performing. Another 2 units showed no improvement and were selected as low performing. A blinded, independent observer conducted interviews with unit management, physicians, and nurses, based on the Hospital Survey on Patient Safety Culture. Safety culture was categorized as pathological (lowest level), reactive, bureaucratic, proactive, or generative (highest level). RESULTS: Overall, 3 units showed a proactive or generative safety culture and 2 units had bureaucratic or pathological safety cultures. When comparing compliance and interview results, high-performing units showed high levels of safety culture, while low-performing units showed low levels of safety culture. CONCLUSIONS: Safety culture is associated with the ability to improve hand hygiene. Interventions may not be effective when applied in units with low levels of safety culture. Although additional research is needed to corroborate our findings, the safety culture on a unit can benefit from enhancement strategies such as team-building exercises. Strengthening the safety culture before implementing interventions could aid improvement and prevent nonproductive interventions. Infect Control Hosp Epidemiol 2017:1–

Evaluation of an infection control link nurse program: an analysis using the RE-AIM framework

BACKGROUND: Important elements of programs that train and support infection control link nurses (ICLN) are the engagement of stakeholders, support from hospital and ward management and a structure for iterative improvement. The effects of programs, that combine all these elements, are unknown. We evaluated such a comprehensive program to explore its impact on link nurses and infection prevention practices and routines. METHODS: We used the RE-AIM framework, a robust, evidence-based framework within the field of Implementation Science, to evaluate the impact of our ICLN training and support program. We used a mixed methods approach and organized the outcomes along its five dimensions: Reach, Effectiveness, Adoption, Implementation and Maintenance. RESULTS: Between 2014 and 2018, on average 91% of the inpatient wards and 58% of the outpatient clinics participated in the program (Reach) and impacted guideline adherence in inpatient wards. Link nurses felt engaged and empowered, and perceived their contribution to these results as pivotal. Ward managers confirmed the value of ICLN to help with implementing IPC practices (Effectiveness). The program was adopted both at the hospital and at the ward level (Adoption). Based on ongoing evaluations, the program was adapted by refining education, training and support strategies with emphasis on ward specific aspects (Implementation). The ICLN program was described as a key component of the infection prevention policy to sustain its effects (Maintenance). CONCLUSIONS: Our infection control link nurse program helped ICLN to improve infection prevention practices, especially in inpatient wards. The key to these improvements lay within the adaptability of our link nurse program. The adjustments to the program led to a shift of focus from hospital goals to goals tailored to the ward level. It allowed us to tailor activities to align them with the needs specific to each ward

Effectiveness of a Behavioral Approach to Improve Healthcare Worker Compliance With Hospital Dress Code

BACKGROUND The VU University Medical Center, a tertiary-care hospital in the Netherlands, has adopted a dress code based on national guidelines. It includes uniforms provided by the hospital and a bare-below-the-elbow' policy for all healthcare workers (HCWs) in direct patient care. Because compliance was poor, we sought to improve adherence by interventions targeted at the main causes of noncompliance. OBJECTIVE To measure compliance with the dress code, to assess causes of noncompliance and to assess whether a behavioral approach (combing a nominal group technique with participatory action) is effective in improving compliance METHODS Between March 2014 and June 2016, a total of 1,920 HCWs were observed in hospital hallways for adherence to the policy, at baseline, and at follow-up measurements. Based on the outcome of the baseline measurement, a nominal group technique was applied to assess causes of noncompliance. The causes revealed served as input for interventions that were developed, prioritized, and tailored to specific groups of HCWs and specific departments through participatory action. RESULTS We identified lack of knowledge, lack of facilities, and negative attitudes as the main causes of noncompliance. The importance of each cause varied for different groups of HCWs. Tailored interventions targeted at these causes increased overall compliance by 39.6% (95% CI, 31.7-47.5). CONCLUSION The combination of a nominal group technique and participatory action approach is an effective method to increase and sustain compliance with hospital dress code. This combined approach may also be useful to improve adherence to other guidelines. Infect Control Hosp Epidemiol 2017;38:1435-144

Nitrous oxide abuse leading to extreme homocysteine levels and thrombosis in young adults: a case series

BACKGROUND: Neurologic complications from recreational use of nitrous oxide (N2O), which are attributed to vitamin B12 deficiency, have been well documented. With increasing dosages and frequency of N2O use, an additional association with thromboembolisms is becoming apparent. OBJECTIVES: To assess thrombotic complications of recreational N2O use. METHODS: All medical charts at the largest hospital in Amsterdam were searched for N2O use and subsequent neurologic and/or thrombotic events. For patients with thrombotic events, we extracted data on the risk factors for arterial and venous thrombosis as well as serum vitamin B12 and homocysteine concentrations. RESULTS: Between January 2015 and May 2021, 326 patients who reported recreational use of N2O were identified; of these, 17 (5%) patients presented with severe thrombotic events associated with N2O (71% men; median age, 26 years [range, 18-53 years]), 5 patients presented with arterial thrombosis (3 with acute coronary syndrome, 1 with femoral artery thrombosis, and 1 with middle cerebral artery thrombus), and 12 patients presented with venous thromboembolisms (10 with pulmonary embolisms, 1 with portal vein thrombosis and 1 with cerebral vein thrombosis). Additionally, homocysteine were concentrations severely increased (median, 125 μmol/L [range, 22-253 μmol/L]; reference, <15 μmol/L). Patients reported use of 400 to 6000 g (ie, 50-750 balloons) of N2O in 1 day. Fifty percent of these patients had experienced neurologic symptoms before the thrombotic event. CONCLUSION: We describe an alarming incidence of serious thrombotic events among young adults after excessive recreational use of N2O, accompanied by extremely high homocysteine concentrations. The upward trend in the recreational use of N2O warrants more awareness of its dangers among both users and medical professionals. Furthermore, these findings could reopen the discussion on possible associations between hyperhomocysteinemia and thrombosis mediated through N2O

Practices in prescribing protein substitutes for PKU in Europe: No uniformity of approach

Background: There appears little consensus concerning protein requirements in phenylketonuria (PKU). Methods: A questionnaire completed by 63 European and Turkish IMD centres from 18 countries collected data on prescribed total protein intake (natural/intact protein and phenylalanine-free protein substitute [PS]) by age, administration frequency and method, monitoring, and type of protein substitute. Data were analysed by European region using descriptive statistics. Results: The amount of total protein (from PS and natural/intact protein) varied according to the European region. Higher median amounts of total protein were prescribed in infants and children in Northern Europe (n. =. 24 centres) (infants &lt;. 1. year, >. 2-3. g/kg/day; 1-3. years of age, >. 2-3. g/kg/day; 4-10. years of age, >. 1.5-2.5. g/kg/day) and Southern Europe (n. =. 10 centres) (infants &lt;. 1. year, 2.5. g/kg/day, 1-3. years of age, 2. g/kg/day; 4-10. years of age, 1.5-2. g/kg/day), than by Eastern Europe (n. =. 4 centres) (infants &lt;. 1. year, 2.5. g/kg/day, 1-3. years of age, >. 2-2.5. g/kg/day; 4-10. years of age, >. 1.5-2. g/kg/day) and with Western Europe (n. =. 25 centres) giving the least (infants &lt;. 1. year, >. 2-2.5. g/kg/day, 1-3. years of age, 1.5-2. g/kg/day; 4-10. years of age, 1-1.5. g/kg/day). Total protein prescription was similar in patients aged >. 10. years (1-1.5. g/kg/day) and maternal patients (1-1.5. g/kg/day). Conclusions: The amounts of total protein prescribed varied between European countries and appeared to be influenced by geographical region. In PKU, all gave higher than the recommended 2007 WHO/FAO/UNU safe levels of protein intake for the general population
