Reducing the frequency of hand hygiene to maintain skin integrity among nurses in the growing care unit: A pilot study

Hand Hygiene Practices and Risk and Prevention of Hand Eczema during the COVID-19 Pandemic.

To observe the effect of acupuncture and moxibustion on the water content of stratum corneum (WCSC), expression of serum inflammatory factors and aquaporin 3 (AQP3) in skin, lung and rectum in guinea pigs with eczema of skin damp-heat accumulation, and to explore the possible mechanism of acupuncture and moxibustion for regulating skin barrier function. A total of 24 male albino guinea pigs were randomly divided into a blank group (n=6) and a modeling group (n=18). The guinea pigs in the modeling group were induced by 2,4-dinitrochlorobenzene (DNCB) to establish the eczema model of skin damp-heat accumulation. The guinea pigs with successful modeling were further randomly divided into a model group, a medication group and an acupuncture-moxibustion group, 6 guinea pigs in each group. The guinea pigs in the medication group were treated with loratadine tablets (0.8 mg/kg) by gavage, once a day for 7 days; the guinea pigs in the acupuncture-moxibustion group were treated with acupuncture at "Feishu" (BL 13), "Pishu" (BL 20), "Quchi" (LI 11), "Zusanli" (ST 36) and "Xuehai" (SP 10); at the same time, moxibustion was applied at "Feishu" (BL 13) and "Zusanli" (ST 36), moxibustion intervention for 10 min and needle retaining for 15 min at each acupoint, once a day for 7 days. The eczema area and severity index (EASI) score was evaluated before and After intervention, and WCSC and trans-epidermal water loss (TEWL) were measured by skin tester. After intervention, The HE staining was used to observe the changes of skin histomorphology in each group; ELISA was used to measure the contents of serum immunoglobulin E (IgE), interleukin (IL)-4 and IL-17; Western blot was used to measure the protein expression of AQP3 in skin, lung and rectum. Before the intervention, compared with the blank group, the EASI scores and TEWL were increased in the remaining groups (P<0.01), and the WCSC was decreased (P<0.01). After the intervention, compared with the model group, the EASI scores and TEWL were decreased (P<0.05, P<0.01), and WCSC was increased (P<0.01) in the medication group and the acupuncture-moxibustion group. The epidermal structure in the blank group was complete and the fibers in the dermis were arranged orderly; in the model group, epidermal hyperkeratosis, proliferation of granular layer, spinous cell layer and basal layer, and disordered arrangement of dermal fibers and infiltration of inflammatory cells were observed. The morphological performance in the medication group and the acupuncture-moxibustion group was better than that in the model group. Compared with the blank group, the contents of serum IgE and IL-17 were increased (P<0.01), and the content of serum IL-4 and the protein expression of AQP3 in skin, lung and rectum were decreased in the model group (P<0.01, P<0.05). Compared with the model group, the contents of serum IgE and IL-17 were decreased and the contents of serum IL-4 were increased in the medication group and the acupuncture-moxibustion group (P<0.01), and the protein expression of AQP3 in skin, lung and rectum in the acupuncture- moxibustion group were increased (P<0.05). Compared with the medication group, the contents of serum IgE and IL-17 were increased (P<0.01), and the content of serum IL-4 was decreased (P<0.01) in the acupuncture-moxibustion group. Acupuncture and moxibustion could improve the epidermal water metabolism and skin tissue morphology in guinea pigs with eczema of skin damp-heat accumulation. Its mechanism may be related to regulating inflammatory factors, up-regulating the expression of AQP3, and then repairing the skin barrier function.

To study the impact of a quality improvement (QI) initiative using care bundle approach on Central-line associated bloodstream infections (CLABSI) rates. A QI team for infection control in NICU was formed in a tertiary-care neonatal intensive care unit (NICU) from June 2015 to August 2016. Baseline data were collected over first 3 months followed by the intervention period of 1 year. Measures with respect to strengthening hand hygiene and central line bundle care were implemented during the intervention period. Audits assessing the compliance to hand hygiene and CLABSI bundle protocols were used as process indicators. Multiple PDSA cycles were used to strengthen the practices of proposed interventions, documentation of data and audits of the processes during the study period. The QI initiative achieved a 89% reduction in CLABSI from the baseline rate of 31.7 to 3.5 per 1000 line-days. The blood stream Infections reduced from 7.3 to 2.3 per 1000 patient-days. The overall mortality showed a reduction from 2.9% to 1.7% during the intervention period. There was a significant improvement in compliance with hand hygiene protocol and compliance with CLABSI protocols. This study demonstrated that simple measures involving hand hygiene and strengthening of the care bundle approach through quality improvement could significantly reduce the blood stream Infections and CLABSI rates.

BackgroundGood hand hygiene compliance is essential to prevent nosocomial infections in healthcare settings. Direct observation of hand hygiene compliance is the gold standard but is time consuming. An electronic dispenser with built-in wireless recording equipment allows continuous monitoring of its usage. The purpose of this study was to monitor the use of alcohol-based hand rub dispensers with a built-in electronic counter in a neonatal intensive care unit (NICU) setting and to determine compliance with hand hygiene protocols by direct observation.MethodsA one-year observational study was conducted at a 27 bed level III NICU at a university hospital. All healthcare workers employed at the NICU participated in the study. The use of bedside dispensers was continuously monitored and compliance with hand hygiene was determined by random direct observations.ResultsA total of 258,436 hand disinfection events were recorded; i.e. a median (interquartile range) of 697 (559–840) per day. The median (interquartile range) number of hand disinfection events performed per healthcare worker during the day, evening, and night shifts was 13.5 (10.8 - 16.7), 19.8 (16.3 - 24.1), and 16.6 (14.2 - 19.3), respectively. In 65.8% of the 1,168 observations of patient contacts requiring hand hygiene, healthcare workers fully complied with the protocol.ConclusionsWe conclude that the electronic devices provide useful information on frequency, time, and location of its use, and also reveal trends in hand disinfection events over time. Direct observations offer essential data on compliance with the hand hygiene protocol. In future research, data generated by the electronic devices can be supplementary used to evaluate the effectiveness of hand hygiene promotion campaigns.

This study was purposed to determine the effects of newly formulated topical skin-care cream (w/o emulsion) of Hippophae rhmanoides versus its vehicle (Base) as control on stratum corneum (SC) water content and transepidermal water loss (TEWL). Concentrated H. rhamnoids (sea Buckthorn) fruit extract was entrapped in the inner aqueous phase w/o emulsion. Newly formulated and previously evaluated base (containing no active material) and a formulation (containing 1% concentrated extarct of H. rhmanoides) were applied. Both the base and formulation were applied to the cheeks of 21 healthy human volunteers for a period of 8 weeks. SC water content and TEWL were monitored every week to measure any effect produced by these topical creams. The vehicle (base) showed insignificant (p≥ 0.05) effects whereas the formulation showed statistically significant (p≤0.05) decrease in TEWL. SC water content was significantly (p≤0.05) increased by the formulation. The newly formulated cream of H. rhmanoides fruit extract, applied is suitable for improvement and quantitative monitoring of skin hydration level (SC water content/ moisturising effects) and reducing TEWL in people with dry skin. Key words: Sea Buckthorn, skin, Stratum corneum (SC), water content and transepidermal water loss (TEWL).

Hand eczema and its severity in nonmedical personnel: A study of the use of hand sanitizer on transepidermal water loss and skin capacitance

Our goal for this study was to quantify healthcare provider compliance with hand hygiene protocols and develop a conceptual framework for increasing hand hygiene compliance in a low-resource neonatal intensive care unit. We developed a 3-phase intervention that involved departmental discussion, audit, and follow-up action. A 4-month unobtrusive audit during night and day shifts was performed. The audit results were presented, and a conceptual framework of barriers to and solutions for increasing hand hygiene compliance was developed collectively. A total of 1308 hand hygiene opportunities were observed. Among 1227 planned patient contacts, hand-washing events (707 [58.6%]), hand rub events (442 [36%]), and missed hand hygiene (78 [6.4%]) events were observed. The missed hand hygiene rate was 20% during resuscitation. Missed hand hygiene opportunities occurred 3.2 times (95% confidence interval, 1.9-5.3 times) more often during resuscitation procedures than during planned contact and 6.14 times (95% confidence interval, 2.36-16.01 times) more often when providers moved between patients. Structural and process determinants of hand hygiene noncompliance were identified through a root-cause analysis in which all members of the neonatal intensive care unit team participated. The mean hand-washing duration was 40 seconds. In 83% of cases, drying hands after washing was neglected. Hand recontamination after hand-washing was seen in 77% of the cases. Washing up to elbow level was observed in 27% of hand-wash events. After departmental review of the study results, hand rubs were placed at each bassinet to address these missed opportunities. Hand hygiene was suboptimal during resuscitation procedures and between patient contacts. We developed a conceptual framework for improving hand hygiene through a root-cause analysis.

BackgroundTo determine hand hygiene compliance before and after an intervention campaign in critical care units, this study was carried out in the Intensive care unit (ICU), Neonatal intensive care unit (NICU), Burns unit (BU) and the Kidney unit of the King Abdul Aziz Specialist Hospital, Taif, Saudi Arabia. The observation using the WHO hand hygiene protocol took place in four phases with phase I, between April 24-May 06 2010 and phase II from May 29-June 09 2010. An educational intervention took place between the Phases I and II. Follow-up Phases III and IV were from 01–15 October 2010 and 15–30 March 2011 respectively.Findings1,975 hand hygiene opportunities comprising of 409 in Phase I, 406 in Phase II, 620 in Phase III and 540 Phase IV were observed. Compliance rate was 67% pre-intervention, 81% in phase II, declining to 59% and 65% in phases III and IV. Increased compliance in the ICU from 39% in Phase I to 81% in Phase IV (p < 0.05) was sustained throughout the study. Highest compliance rates were recorded among nurses in all phases. The improved compliance for physicians observed in the post-intervention phase was lost in follow-up phases. Missed opportunities for hand hygiene were before patient contact, after touching patient’s surrounding and before aseptic techniques. Team-work and leadership were identified as enhancing factors for compliance.ConclusionThe WHO hand hygiene strategy combined with health education, continuous evaluation and team approach resulted in increased compliance but this was not sustained in certain critical care areas.

Objective To evaluate the safety of a hyaluronic acid-containing dressing for wound healing of facial skin in patients with freckles after intensive pulsed light (IPL) therapy.Methods A multicenter,randomized,open,controlled clinical trial was conducted.A total of 298 IPL-treated patients with freckles were recruited into this study.After IPL therapy,all the patients were randomly divided into two groups to be topically treated with a hyaluronic acid-containing dressing (experiment group) or a sodium chloride physiological solutioncontaining face mask (control group).Skin physiological parameters,including sebum content,water content in stratum corneum,and transepidermal water loss,were invasively measured at the baseline,on day 3,7 and 14 after the start of topical treatment.The formation and desquamation of irradiation-induced crusts were observed,the degree of patient satisfaction was evaluated,and adverse reactions were recorded.Results The water content in stratum corneum and transepidermal water loss were (25.32 ± 4.14) ％ and (14.08 ± 3.32) g·cm-2·h-1,respectively,in the experimental group on day 14,significantly different from those before treatment (both P＜0.01) and those in the control group on day 14 (both P ＜ 0.01).Skin sebum content in the experiment group showed no significant changes during the 14-day treatment (P ＞ 0.05),and was similar to that in the control group on day 14 (P ＞ 0.05).The percentage of patients experiencing the initial desquamation of crusts within three days and that experiencing complete desquamation of crusts within seven days were significantly different between the experiment group and control group (x2 =7.774,P ＜ 0.01; x2 =4.692,P ＜ 0.05).Statistical differences were observed in the degree of patient satisfaction between the two groups (P ＜ 0.05).No adverse reactions were reported during the trial.Conclusion The hyaluronic acid-containing dressing can restore skin barrier function with a good safety profile,and may serve as an adjuvant therapy for wound healing of facial skin after IPL irradiation.

Background: A Quality Improvement (QI) initiative to reduce invasive Staphylococcus aureus (SA) infections in a level IV neonatal intensive care unit (NICU) successfully eliminated Methicillin-resistant (MRSA) but not Methicillin-susceptible (MSSA) infections. A combination of SA whole genome sequencing (WGS) and environmental culturing helped to better understand the epidemiology of MSSA colonization and infection in the NICU and drive new infection prevention interventions. Methods: Environmental surveillance of high-touchpoint surfaces for SA was performed using Dey and Engley neutralizing agar. Selected isolates were confirmed as SA using Columbia Sheep’s Blood agar and Staphaurex testing. Statistical analyses examined correlations between monthly effective cleaning, hand hygiene compliance, and colonization rates. To better understand MSSA spread in the NICU, WGS was performed on a convenience sample of 42 MSSA isolates, sampled one month before and after an invasive MSSA infection. Data extracted from electronic health records were used for retrospective room tracing of colonized patients with related isolates to determine modes of transmission. Results: WGS analysis MSSA isolates revealed four MSSA strains from 29 patients suggesting within unit transmission, while 13 patients were colonized with unique MSSA isolates suggesting external sources. Retrospective room tracing of colonized patients identified three transmission patterns: subsequent room occupant transmission, intra-pod spread, and inter-pod transmission without patient transfer, with evidence that these strains were endemic within the unit for at least 3-12 months. Statistical analyses showed no significant correlation between environmental cleaning or hand hygiene compliance and colonization rates. Conclusions: Persistent MSSA colonization and invasive infections in the NICU result from both within-unit transmission and the introduction of unique isolates. These findings are being used to inform the development of new interventions, including updated below-the-elbow hand hygiene protocols, revised environmental cleaning plans, nurse-parent communication training, and a virtual reality hand hygiene training program for parents and staff. WGS of pathogenic organisms is a useful tool to drive QI initiatives aimed at reducing hospital-acquired infections.

Background: Hand hygiene (HH) is a cornerstone of programmes to prevent healthcare associated infections (HAI) globally, but HH interventions are seldom reported from African neonatal units. Methods: We conducted a quasi-experimental study evaluating the impact of a multi-modal intervention (SafeHANDS) on HH compliance rates, alcohol-based handrub (ABHR) usage, the Hand Hygiene Self-Assessment Framework (HHSAF) score, and healthcare-associated bloodstream infection (HA-BSI) rates at a 132-bed South African neonatal unit (4 wards and 1 neonatal intensive care unit [NICU]). The intervention included a campaign logo, HH training, maternal education leaflets, ABHR bottles for staff, and the setting of HH performance targets with feedback. Three 5-month study phases were completed in July 2020 (baseline), December 2020 (early) and May 2021 (intensive). Results: A total of 2430 HH opportunities were observed: 1002 (41.3%) at baseline, 630 (25.9%) at early and 798 (32.8%) at intensive study phases. At baseline, the overall neonatal unit HH compliance rate was 61.6%, ABHR use was 70 mL/patient day, and the baseline HHSAF score was ‘basic’ (165). The overall neonatal unit HH compliance rate was unchanged from baseline to intensive phases (617/1002 [61.6%] vs. 497/798 [62.3%]; p = 0.797). The ABHR use remained similar between phases (70 versus 73 mL/patient day). The HHSAF score improved to ‘intermediate’ level (262). There was no change in the neonatal unit HA-BSI rate. Conclusion: Despite improvement in the HHSAF score, no improvement in overall HH compliance rates, ABHR usage, or HA-BSI rates was observed. Future HH interventions in resource-limited neonatal units should incorporate implementation science and behaviour modification strategies to better understand the barriers and facilitators of HH best practice.

The pH of the skin is tightly regulated by endogenous buffering systems. We examined the influence of buffers of different pH and composition on skin barrier repair, pH, inflammation, and epidermal thickness/proliferation/differentiation. After tape-stripping in hairless mice buffers with pH 4–7 were applied in patch test chambers. After removal of the chambers, skin pH and transepidermal water loss (TEWL) were monitored for 24 h, and biopsies were taken for histology/immunohistology. Hairless mice showed a basal skin pH of about 5.8. Following barrier disruption and application of water, the pH increased by 0.6 units; increase in pH was reduced by the pH 4 glycolate buffer, unchanged by pH 4 citrate and pH 5.5 buffers, and even increased by the pH 7 buffer. pH 5.5, pH 4 citrate, and pH 4 glycolate buffers led to a slight, while the pH 7 buffer led to a significant increase in TEWL after barrier disruption compared to water. The pH 7 buffers led to a significant increase in epidermal thickness/proliferation/differentiation and inflammation after barrier disruption, whereas buffers with pH 4 and 5.5 caused a slight increase. In conclusion, only the pH 4 glycolate buffer significantly reduced the skin barrier disruption-related increase in skin pH. This was accompanied by only slight increase in epidermal thickness and inflammation compared to water. Application of the pH 7 buffer led to a significant increase in the skin pH, TEWL, epidermal thickness, and inflammation. The results are important for the formulation of topical products for effective acidification in pathological skin conditions.

Surgical site infection (SSI) remains a persistent and morbid problem in colorectal surgery. Key to its pathogenesis is the degree of intraoperative bacterial contamination at the surgical site. The purpose of this study was to evaluate a novel wound retractor at reducing bacterial contamination. A prospective multicenter pilot study utilizing a novel wound retractor combining continuous irrigation and barrier protection was conducted in patients undergoing elective colorectal resections. Culture swabs were collected from the incision edge prior to device placement and from the exposed and protected incision edge prior to device removal. The primary and secondary endpoints were the rate of enteric and overall bacterial contamination on the exposed incision edge as compared to the protected incision edge, respectively. The safety endpoint was the absence of serious device-related adverse events. A total of 86 patients were eligible for analysis. The novel wound retractor was associated with a 66% reduction in overall bacterial contamination at the protected incision edge compared to the exposed incision edge (11.9 vs. 34.5%, P < 0.001), and 71% reduction in enteric bacterial contamination (9.5% vs. 33.3%, P < 0.001). The incisional SSI rate was 2.3% in the primary analysis and 1.2% in those that completed the protocol. There were no adverse events attributed to device use. A novel wound retractor combining continuous irrigation and barrier protection was associated with a significant reduction in bacterial contamination. Improved methods to counteract wound contamination represent a promising strategy for SSI prevention (NCT 02413879).

Introduction: The most effective way to break the chain of transmission of infection in healthcare facility is Hand Hygiene (HH). However, the HH adherence rate/compliance is varying worldwide. Healthcare facilities should follow comprehensive, systematic approach for assessment of HH adherence rate. Periodic monitoring and necessary feedback is critical to improve HH adherence rate/compliance. Aim: To know the impact of the HH training of Healthcare Workers (HCW) on HH adherence rate. Materials and Methods: This prospective study was conducted at SMS Multispecialty Hospital, Ahmedabad, Gujarat, India. The study was conducted for the duration of six months (October 2019-March 2020). Total 416 opportunities were accessed in two sessions {203 pretraining and 213 post-training} among different HCWs of ICU and NICU. HH adherence rate was measured by direct observation methods by trained, non participating neutral person as per World Health Organisation (WHO) HH guidelines. HH training was given to HCWs (doctors, nursing staff and attendant) of Intensive Care Unit (ICU) and Neonatal Intensive Care Unit (NICU). Pre and post-training HH adherence rate was calculated among HCWs of ICU and NICU in respect to WHO’s five movement of HH. Chi-square test was used to do statistical analysis. Results: Pre and post-training HH adherence rate of HCWs of ICU is 41% and 69% respectively. However, pre and post- training HH adherence rate of HCWs of NICU was 52% and 75%, respectively. Both ICU and NICU post-training HH adherence rate of HCWs was improved which was statistically significant (p-value &lt;0.00001). Both pre and post-training, compared to doctors, nursing staff had better HH adherence rate (45%, 67% in ICU and 58% and 78% in NICU). Hand rub was preferred method of HH (93%). Conclusion: The HH training improved the HH adherence rate of HCWs of ICU and NICU. Induction and periodic training of HCWs improves HH adherence rate of HCWs.
