Infection Control Procedures in Commercial Dental Laboratories in Jordan

Infection control awareness level among dental laboratory technicians, Riyadh, Saudi Arabia

Aims and objectives:

Infection control is an essential part in dental practices. Potential disease transmission in the dental lab is well documented. Dental technicians should strictly adhere to the standard precautions in order to prevent potential risks of cross-contamination, thereby producing a safe environment for patients and staff. The aim of this study was to evaluate the knowledge, attitude, and practice among dental lab technicians toward infection control protocols at the dental laboratories of Riyadh.

Materials and methods:

A self-administered questionnaire will be distributed to dental lab technicians working at both private and governmental laboratories in Riyadh, Saudi Arabia. Data were collected from one hundred and twenty-one dental laboratory technicians.

Results:

According to the findings, only 42.9% had an infection control manual display in the dental lab, 43.8% had received infection control training courses as part of their orientation, 40.4% of the technicians had a valid hepatitis B vaccination. Dental technicians are exposed to high risk of injuries, 72.7% of respondents answered Yes, when they were asked about reporting sharp injuries to laboratory administration.

Conclusion:

There was poor compliance to infection control procedures, dental techniques are at increased risk of cross-contamination and infection, they have limited orientation and knowledge on the infection control guideline and policy.

Practices of Infection Control Among Dental Care Providers: A Cross Sectional Study

BACKGROUND

A wide range of microorganisms poses a threat to patients and dental care teams. Implementation of safety guidelines is thus essential to prevent infection in dental clinics.

AIM

To investigate the level of infection-control practices among dental health-care providers in Jordan.

METHODS

A self-administered questionnaire was distributed to dental care providers from hospitals, academic institutions, and dental centres. The questionnaire covered sociodemographic variables, professional characteristics, and recommended guidelines of infection control.

RESULTS

A total of 190 questionnaires were obtained out of 500 distributed questionnnaires (response rate: 38%). Females accounted for 62.6% of the sample and 64.7% were dentists. The majority was vaccinated against hepatitis B (82.1%) and wash their hands as usual behavior before (66.3%) and after (83.2%) treatment. Approximately 87.9% wear gloves and 78.9% wear masks while performing dental procedures. Autoclave sterilization and puncture-resistant containers for sharp instruments were used by 90.5% and 88.4%, respectively. The majority (81.0%) had protocols for emergency treatment of needle stick or other sharps accidents. High volume evacuation was used in 28.6% of public hospitals compared to 19.4% in academic institutions (P<0.01). In addition, surface barriers for dental unit surfaces were used by 70.2% of private dental clinics, 50% of public hospitals, and 36.1% of academic institutions (P<0.001). Finally, compared to dentists, dental support staff showed low compliance with infection-control guidelines.

CONCLUSION

The overall practice of infection-control measures among the participants is very good. Educational programs and training strategies should be implemented to maximize and enhance the compliance of the dental care providers with infection-control guidelines.

Knowledge and practices about sterilization and disinfection

Aims

The aim of the present study was to evaluate the knowledge and practices employed for infection control in dental laboratories.

Materials and Methods

A preformed questionnaire comprised of 16 questions related to infection control measures was prepared. This questionnaire based survey was then conducted among dental technicians of 60 dental colleges in East India. Data were then recorded and analyzed.

Results

Majority of impressions/prosthesis were carried in plastic bags (93.8%) by laboratory attendants to the laboratory. The responses revealed that majority of impressions were received after wearing gloves (54.6%) from dental attendant. Majority of dental technicians (78.1%) admitted in their responses that they are not aware of infection control measures taken in dental laboratory. Only 32.8% technicians were found to practice disinfection procedure after receiving impression/prosthesis in laboratory from dental operatory. Among protective wears, 70.3%, 95.3%, 32.8%, and 92.2% technicians were found to use gloves, Apron, eye shield, and face mask, respectively. Among all respondents, 59.3% were found to be vaccinated for hepatitis B vaccine.

Conclusion

There is lack of knowledge and motivation among dental technician to practice infection control measures in dental laboratories of dental institutes in North India.

Addressing gaps in transversal educational contents in undergraduate dental education. The audio-visual 'pill of knowledge' approach

INTRODUCTION

Training on impression disinfection is often limited to brief explanations in the clinic. This investigation assessed knowledge on this topic amongst clinical students in our university, produced a pill of knowledge to suit their needs, and evaluated its impact and acceptance.

MATERIAL AND METHODS

A pre-post study was designed to identify knowledge gaps using an anonymous, voluntary self-applied questionnaire before and after watching an audio-visual clip (pill of knowledge). All 136 students in the school were invited to enter the study (estimated sample size: 116).

RESULTS

Participants: 109 (26.6% in 3rd year; 37.6% in 4th year and 39.4% in 5th year). Participation dropped 10.29% (n = 95) in the post-intervention survey. Knowledge improvement was higher for those impression materials included in the pill. Most students (68.4%) reported to know more about impression disinfection after the pill and 70.5% felt more able to achieve correct disinfection. The pill was particularly well received (86.3%). All students would recommend it to their peers, and 93.5% are willing to receive pills on other topics.

DISCUSSION

Our results disclosed an important gap in knowledge, which can be filled by a single, brief and concise pill adapted to the intended audience. Once made readily available through digital repositories, it may help solve this problem, given the ubiquitous presence of mobile devices.

CONCLUSIONS

Our results found pills of knowledge as a useful approach to facilitating undergraduates' learning process. This method, using suitable information and communication technologies, has the potential to improve the performance on certain clinical tasks.

Dentists' knowledge, attitudes and practices regarding Hepatitis B and C and HIV/AIDS in Sanandaj, Iran

BACKGROUND

Healthcare workers including physicians, dentists, nurses and laboratory workers are considered to be among the groups at the risk of blood-borne pathogen transmission. Thus, it is necessary to evaluate the Knowledge, Attitude, and Practices (KAP) of dentists regarding infection control and basic principles.

METHODS

This cross-sectional study recruited 106 dentists in Sanandaj, Iran. The dentists' KAP regarding hepatitis B virus (HBV), hepatitis C virus (HCV), and HIV/AIDS were evaluated. Chi-square test, student's t-test, and one-way ANOVA were used to assess differences between the groups. Data were analyzed in Stata 12.

RESULTS

The results showed that the majority of the subjects in the study population (53.8%) were female. The mean ± standard deviation (SD) for age and work experience was 39.6 ± 9.80 and 10.6 ± 8.7 years, respectively. The mean ± SD for knowledge, attitude and practices of participants was 37.3 ± 3.01, 22.9 ± 4.80 and 24.07 ± 5.06, respectively. The results also indicated that dentists' higher level of knowledge about HBV, HCV and HIV/AIDS was significantly influenced by work experience (≥10 years; P < 0.001) and graduation year (after 2006: P < 0.001). Positive attitude towards HBV, HCV and HIV/AIDS was considerably influenced by age group (< 30 years: P = 0.021), work experience (≥10 years: P < 0.001), and workplace (dental office: P = 0.016).

CONCLUSIONS

The results of this study demonstrated a satisfactory level of knowledge and attitude of dentists about HBV, HCV and HIV/AIDS infections, but some gaps were observed, suggesting that higher knowledge level of dentists plays a very important role in forming the attitudes and practices regarding patients with HBV, HCV and HIV/AIDS.

Quality of cross-infection control in dental laboratories. A critical systematic review

Purpose

To identify reported practices for cross-infection control in dental laboratories and to quantify the importance of the flaws encountered.

Data sources

Systematic search (cross-infection AND dental laboratory) at EMBASE, PubMed, SciELO and Scopus databases.

Study selection

Papers reporting on cross-sectional studies providing original data about cross-infection knowledge, practices and attitudes of dental technicians. Papers reporting on a single laboratory or institution were excluded.

Data extraction

Data extraction was undertaken independently by three reviewers using a purpose made form. The outcome of this study was analyzed in five aspects, namely process organization, disinfection, working environment, use of individual protective equipment and vaccination policy.

Results of data synthesis

The systematic search output was 1651 references and 11 papers were finally selected. Flaws were more frequently identified in terms of vaccination policy, biological safety of the working environment and use of individual protective equipment (100%). Slightly better results were found in terms of organization of the cross-infection control process (89.47%) and disinfection practices (85.71%). The application of the formula for disclosing the relative importance of the flaws identified in the literature prioritizes the need for interventions aimed at improving the organization of the cross-infection control procedures, followed by training in item disinfection. The control of the working environment together with the use of individual protective equipments rank closely in importance, followed by the existence of a vaccination policy.

Conclusions

Sub-standard cross-contamination practices seem to be a common finding in dental laboratories, which may well compromise the quality of certain dental treatments.

Compliance with infection control practices when taking dental x-rays: Survey of a Japanese dental school

The aim of this study was to assess knowledge, attitude, behavior, and compliance concerning infection control among dental practitioners in a dental university hospital in Japan. A 12-item questionnaire about infection control during radiographic procedures was distributed to 686 dental personnel working at Osaka Dental University. The questionnaire collected information on occupation and the use of gloves, holders, door handles, control panels, dental chairs, protectors, tube head, tube arms, tube cones, and keyboards for personal computers. To identify misunderstandings about, and thus noncompliance with, current infection control practices, the percentage of correct answers (PCA) was calculated. Understanding and compliance with the current practices was considered low when <75% and high when ≥75%. In addition, contaminated objects in the clinical setting were examined using black light. PCA was low for one question on using gloves in film positioning and high for three questions on using protective film barriers, regardless of the respondents' occupation. PCA was generally high for three questions on practicing hand hygiene before putting on gloves, methods to protect film holders, and methods to protect radiographic equipment, but was low among some subjects. PCA was generally low for four questions on using film protective barriers, developing images from unprotected films, practicing hand hygiene after removing gloves, and awareness of a procedures manual for taking intraoral x-rays, but was high among some subjects. Saliva contamination of radiographic equipment was confirmed by direct visualization using black light. Awareness was low of infection control measures to be used during intraoral projection. This study indicates the need for additional education and training to improve infection control practices, through, for example, using a standard procedures manual for all dental practitioners and visual evidence (visualization) of contamination.

A concealed observational study of infection control and safe injection practices in Jordanian governmental hospitals

BACKGROUND

The recognized international organizations on infection prevention recommend using an observational method as the gold standard procedure for assessing health care professional's compliance with standard infection control practices. However, observational studies are rarely used in Jordanian infection control studies. This study aimed to evaluate injection practices among nurses working in Jordanian governmental hospitals.

METHODS

A cross-sectional concealed observational design is used for this study. A convenience sampling technique was used to recruit a sample of nurses working in governmental hospitals in Jordan. Participants were unaware of the time and observer during the observation episode.

RESULTS

A total of 384 nurses from 9 different hospitals participated in the study. A total of 835 injections events were observed, of which 73.9% were performed without handwashing, 64.5% without gloving, and 27.5% were followed by needle recapping. Handwashing rate was the lowest (18.9%) when injections were performed by beginner nurses. Subcutaneous injections were associated with the lowest rate (26.7%) of postinjection handwashing compared with other routes.

CONCLUSIONS

This study demonstrates the need for focused and effective infection control educational programs in Jordanian hospitals. Future studies should consider exploring the whole infection control practices related to waste disposal and the roles of the infection control nurse in this process in Jordanian hospitals.

Nursing students' knowledge and practices of standard precautions: A Jordanian web-based survey

BACKGROUND

The main purpose of this web-based survey was to evaluate Jordanian nursing students' knowledge and practice of standard precautions.

METHODS

A cross-sectional, descriptive design was used. Six public and four private Jordanian universities were invited to participate in the study. Approximately, seventeen hundred nursing students in the participating universities were invited via the students' portal on the university electronic system. For schools without an electronic system, students received invitations sent to their personal commercial email.

RESULTS

The final sample size was 594 students; 65.3% were female with mean age of 21.2 years (SD=2.6). The majority of the sample was 3rd year students (42.8%) who had no previous experience working as nurses (66.8%). The mean total knowledge score was 13.8 (SD=3.3) out of 18. On average, 79.9% of the knowledge questions were answered correctly. The mean total practice score was 67.4 (SD=9.9) out of 80. There was no significant statistical relationship between students' total knowledge and total practice scores (r=0.09, p=0.032).

CONCLUSION

Jordanian nursing educators are challenged to introduce different teaching modalities to effectively translate theoretical infection control knowledge into safe practices.

Infection control practices among intensive care unit registered nurses: a Jordanian national study

AIMS

This study aimed to evaluate infection control (IC) practices among Jordanian registered nurses (RNs) working in intensive care unit (ICU) settings.

BACKGROUND

The Centers for Disease Control and Prevention (CDC) recommends periodic assessment of IC practices for health care workers as an effective strategy to control infections.

DESIGN

Cross-sectional descriptive design.

METHODS

A stratified, cluster random sampling technique was used. The sample consisted of ICU RNs from all major health care service providers and from all geographical areas in Jordan. The IC-Practices Tool (Cronbach α = 0·88) a self-report instrument was used.

RESULTS

A total of 21 hospitals participated in the study, of which, 8 were governmental, 7 military, 4 private and 2 university-affiliated. The final sample consisted of 247 RNs from 56 critical care units. Of the total sample, 36% of RNs were from governmental hospitals. Of the total sample, 51% were female with a mean age of 28·5 years (SD = 5·2), and 54·7% worked in general ICUs. The mean overall IC practice score was 122·6 (SD = 13·2). Nurses who reported that they had been trained about IC procedures in their hospital scored higher on the IC practice scale (M = 124·3, SD = 12·3) than nurses who never received any IC training in the hospital (M = 117·3, SD = 14·6, p < 0·001).

CONCLUSION

This study demonstrated the importance of conducting IC educational programmes as an effective strategy to increase staff compliance with standard IC practices.

RELEVANCE TO CLINICAL PRACTICE

Educational role of IC nurse is important to enhance RNs compliance with standard IC practices.

Hepatitis B virus infection in dentistry: a forgotten topic

More than two billion people have been infected with hepatitis B virus (HBV). Globally, 350-400 million suffer from chronic HBV infection. It is postulated that dentists and dental staff are infected and transmit the virus to their patients more than any other occupation. The aim of this article is to review the HBV incidence in dental society, the points of view of dentists and their patients regarding transmission of the virus during dental procedures, the occurrence of HBV outbreaks in dental clinics and the importance of methods of preventing HBV infection in dentistry.

A case-control study of risk factors for hepatitis B virus infection in North Jordan

Jordan is a country with intermediate endemicity for hepatitis B virus (HBV) infection where risk factors for viral transmission and their relative contributions are not well known. A case-control study of 100 hepatitis B virus seropositive patients and another 100 seronegative controls was conducted. Univariate analysis and logistic regression model were performed to examine probable risk factors for acquisition of hepatitis B virus infections. Logistic-regression analysis showed that significant risk factors for acquisition of hepatitis B virus infection were sharing toothbrushes (odds ratio = 10.167; 95% confidence interval, 1.181-87.509), unhygienic dental care (odds ratio = 2.455; 95% confidence interval, 1.294-4.658), and living abroad for at least 1 year (odds ratio = 20.018; 95% confidence interval, 2.268-176.685). The presence of these risk factors emphasizes the need for both increasing the use of hepatitis B vaccines and risk-targeted public health education. Development and enforcement of appropriate infection control guidelines for dental care services are also necessary to curtail HBV transmission. Further research that controls for confounding factors is needed to assess the relative contribution of the identified risk factors in the Jordanian community.
