Hand Hygiene Practices and Microbial Investigation of Hand Contact Swab among Physiotherapists in an Ebola Endemic Region: Implications for Public Health

Application of the behaviour-centred design to understand facilitators and deterrents of hand hygiene among healthcare providers: findings from a formative phase of a cluster randomised trial in the Kampala Metropolitan area

BACKGROUND

Hand hygiene is known to reduce healthcare-associated infections. However, it remains suboptimal among healthcare providers. In this study, we used the Behaviour-centered Design approach to explore the facilitators and deterrents to hand hygiene among healthcare providers in the Kampala Metropolitan area, Uganda.

METHODS

We conducted a formative qualitative study as part of a cluster randomised trial in 19 healthcare facilities (HCFs). The study used 19 semi-structured and 18 key informant interviews to collect data on hand hygiene status and facilitators and deterrents of hand hygiene. Research assistants transcribed verbatim and used a thematic framework aided by Nvivo 14.0. to undertake analysis. We used thick descriptions and illustrative quotes to enhance the credibility and trustworthiness of our findings.

RESULTS

About 47.4% of the HCFs had sufficient hand hygiene infrastructure, and 57.9% did not report total compliance with hand hygiene during patient care. The physical facilitator for hand hygiene was the presence of constant reminders such as nudges, while the biological included the frequency of patient contact and the nature of clinical work. The only biological deterrent was the heavy workload in HCFs. The executive brain facilitators included knowledge of workplace health risks, infection prevention and control (IPC) guidelines, and a positive attitude. A negative attitude was the executive brain deterrent to hand hygiene. Recognition, rewards, and fear of infections were the only motivated brain facilitators. Behavioural setting facilitators included proximity to functional hand hygiene infrastructure, the existence of active IPC committees, good leadership, and the availability of a budget for hand hygiene supplies. Behavioural setting deterrents included the non-functionality and non-proximity to hand hygiene infrastructure and inadequate supplies.

CONCLUSIONS

The study revealed low compliance with hand hygiene during the critical moments of patient care and inadequacy of hand hygiene infrastructure. The deterrents to hand hygiene included a heavy workload, negative attitude, inadequate supplies, non-functionality, and long distance to hand washing stations. Facilitators included constant reminders, fear of infections, frequency of patient contact and nature of clinical work, positive attitude, knowledge of IPC guidelines, recognition and reward, good leadership, availability of budgets for hand hygiene supplies, availability and proximity to hand hygiene supplies and infrastructure and active IPC committees.

The barriers and facilitators to hand hygiene practices in Nigeria: A qualitative study: "There are so many barriers ... the barriers are limitless."

BACKGROUND

Health care associated infections (HCAIs) are a global challenge and hand hygiene is the primary measure to reduce these. In developing countries, patients are between 2 and 20 times more likely to acquire an HCAI compared with developed countries. Estimates of hand hygiene in Sub-Saharan Africa suggests 21% concordance. There are few studies investigating barriers and facilitators and those published tend to be surveys. This study aimed to understand barriers and facilitators to hand hygiene in a hospital in Nigeria.

METHODS

A theoretically underpinned in-depth qualitative interview study with thematic analysis of nurses and doctors working in surgical wards.

RESULTS

There were individual and institutional factors constituting barriers or facilitators: (1) knowledge, skills, and education, (2) perceived risks of infection to self and others, (3) memory, (4) the influence of others and (5) skin irritation. Institutional factors were (1) environment and resources and (2) workload and staffing levels.

CONCLUSIONS

Our study presents barriers and facilitators not previously reported and offers nuances and detail to those already reported in the literature. Although the primary recommendation is adequate resources, however small local changes such as gentle soap, simple skills and reminder posters and mentorship or support could address many of the barriers listed.

Effective Handwashing Practice in Dilla University Referral Hospital; Duration of Hand Rubbing and the Amount of Water as Key Enablers

Background

Ineffective hand hygiene in healthcare settings is a global challenge that is associated with a high rate of nosocomial infections. The study aimed to measure the effectiveness of handwashing at Dilla University referral hospital.

Method

This study consisted of 2 parts; the survey work and laboratory analysis. A total of 63 participants were selected to take surveys using an interviewer-administered questionnaire to collect the data regarding the socio-demographic and hand hygiene-related practices. A laboratory tests (swab test) was used to assess handwashing effectiveness from 63 participants by taking 126 swab test (63 before and after hand washing sessions). A swab test was collected from the palms of each participant before and after hand washing using a sterile technique. The cultures were then incubated aerobically overnight at 37°C, and examined for microbial growth. The bacterial load was reported as the number of colony-forming units (CFU).

Result

The proportion of effective hand washing in Dilla University Referral Hospital was 82.5%. The mean colony-forming unit before and after handwashing were 55 and 2 CFU/ml, respectively with an average reduction of 94.6% in terms of CFU/ml. The mean amount of water used for effective handwashing was 336.03 (±219.46) ml. There was a significant mean difference in the amount of water used and duration of hand rubbing between effective and non-effective handwashing among the participants (P < 0.01). The bacterial load before and after handwashing indicated that there was a significant (53.3 mean CFU) reduction in bacterial load after handwashing practice which indicated that the handwashing intervention in the Referral hospital was effective (P < 0.01).

Conclusion

The proportion of effective Hand washing in Dilla University referral Hospital was 82.5% with a 94.6% reduction in terms of (CFU/ml). The amount of water use and the duration of hand rubbing showed a significant difference in the reduction of the microbial load.

Cumplimiento de una estrategia de higiene de las manos en ambientes asistenciales

Introducción: Si bien la higiene de las manos es la medida más importante en la mitigación del riesgo biológico en ambientes hospitalarios, evidencia científica muestra un escaso cumplimiento de las recomendaciones entre los trabajadores asistenciales. Objetivo: Evaluar el cumplimiento de cinco dimensiones que fortalecen la estrategia de higiene de las manos para la prevención del riesgo biológico en ambientes asistenciales. Método: Estudio observacional, de corte transversal, en cinco instituciones prestadoras de servicios de salud. Se aplicó estadística descriptiva. Con el Test de Medianas se evaluó si había diferencias significativas entre el grupo de profesionales por institución de salud, considerando significante una p ≤ 0,05. El análisis finalizó con un análisis discriminante. Resultados: La representatividad estuvo en las instituciones hospitalarias de primer nivel en las cuales el personal de enfermería, seguido por los médicos, tuvo un mejor cumplimiento del protocolo de lavado de manos. Este porcentaje se vio impactado por el menor cumplimiento de suministro de insumos e infraestructura. Hay una perfecta diferenciación entre los resultados del municipio de Cali con relación al de Caicedonia, en contraste con los de Popayán, Buga y Buenaventura. Conclusión: Se encontró un incumplimiento del protocolo de higiene de las manos, con una calificación inaceptable para los factores de insumos/infraestructura y técnica de higiene de las manos, respectivamente.  

Barriers to hand hygiene practices among health care workers in sub-Saharan African countries: A narrative review

BACKGROUND

Hand hygiene (HH) is the primary measure in the prevention of health care-associated infections; however, from published studies, compliance of health care workers (HCWs) to HH guidelines is low. There is currently no review on HH compliance rates in developing countries, specifically sub-Saharan Africa (SSA), or the barriers to compliance. We therefore, through a narrative review, sought to identify the compliance with and the barriers to HH in SSA.

METHODS

From 3 databases, we performed a search of peer-reviewed studies from SSA, conducted among HCWs, published in the English language between 2005 and 2017. Only studies that reported HH compliance and/or barriers were included.

RESULTS

A total of 278 articles were identified, and the final sample of 27 articles was analyzed in full length. Overall, the HH compliance rate was estimated to be 21.1%, and doctors had better compliance irrespective of the type of patient contact. The main barriers identified were heavy workload, infrastructural deficit (eg, lack of water, soap, hand sanitizers, and blocked/leaking sinks), and poorly positioned facilities.

CONCLUSIONS

HH compliance is poor among SSA HCWs. There is a need for more reports of HH compliance in SSA, and emphasis needs to be placed on surgical wards in which surgical site infections-the most common form of health care-associated infections in SSA-are most likely to occur. Barriers identified in this review are consistent with the findings of studies conducted elsewhere; however, it appears that heavy workload, infrastructural deficit, and poorly positioned facilities are more likely in developing countries.
