Knowledge, attitudes and beliefs regarding HIV among medical students in Zagreb, Croatia

BACKGROUND

Medical students, as future health-care providers (HCPs) play a significant role in shaping attitudes towards people living with HIV/AIDS (PLWHA) and should possess adequate knowledge of this infection. The study aim was to assess knowledge about HIV among medical students of the University of Zagreb School of Medicine, and to determine the level of discriminatory attitudes towards PLWHA.

METHODS

We assessed knowledge about epidemiology, treatment, and prevention of HIV by using closed-ended and multiple-choice questions. Likert-scale questions were employed to determine attitudes towards PLWHA. Bivariate and multivariate ordinal logistic regression was used to assess correlates of certain discriminatory attitudes.

RESULTS

561 medical students participated, with 46.7% attending preclinical courses. Overall, 42.1% of students think they received sufficient information on HIV/AIDS during elementary and high school education. Among clinical students, 42.6%, 20.8% and 11.8% estimated accurately transmission risk after a needle injury, unprotected vaginal, and anal intercourse, respectively. 66.8% of clinical students were aware that treatment can prevent AIDS, while 58.7% and 69.8% were familiar with the rationale of using pre-exposure (PrEP) and post-exposure prophylaxis (PEP). In the multivariate analysis, individuals lacking infectology course attendance (aOR = 1.45; CI: 1.00-2.09) and those unaware of transmission routes (aOR = 1.49; CI: 1.06-2.09) showed higher odds of advocating HIV status disclosure compared to those who did not yet attend an infectology course. Students supporting extra protection for handling PLWHA bodily fluids were more likely to support refusal to treat PLWHA (aOR = 1.80; CI: 1.22-2.69) compared to those who did not support that opinion. Males were more inclined to state that they would refuse to treat PLWHA (aOR = 1.66; CI: 1.11-2.50) and disclose their HIV status (aOR = 1.62; CI: 1.17-2.27) than females. Overestimating needle injury transmission risk raised treatment refusal likelihood (aOR = 2.22; CI = 1.29-3.92) compared to those accurately informed of this risk.

CONCLUSION

Results indicate lack of knowledge of HIV transmission risks after specific exposures and about PrEP, PEP and treatment effectiveness. Gender and knowledge about HIV transmission risks influence students' attitudes towards PLWHA. Medical education should be focused on fostering correct attitudes and addressing stigma, which undermines prevention and treatment outcomes of PLWHA.

Using the Theory of Planned Behaviour to assess nursing and allied health students' knowledge and intention to care for patients with COVID-19

AIMS AND OBJECTIVES

To assess nursing and allied health students' demographics, knowledge and intentions to care for patients with an infectious disease, COVID-19.

BACKGROUND

COVID-19 has caused a public health crisis and worldwide panic. Little is known about students' knowledge levels and intentions to care for infected patients during pandemics.

DESIGN

A quantitative, cross-sectional study.

METHOD

A cross-sectional study with a convenience sample (N = 480) of nursing and allied health students was analysed using the Mann-Whitney and Spearman's correlation tests.

RESULTS

At least 60% of the participants attained high scores for 16 of the 22 items on the knowledge scale. Knowledge was positively associated with attitude (rs  = .19, p < .01) and perceived behavioural control (rs  = .38, p < .01) and negatively associated with subjective norms (rs  = -.11, p < .05). Senior students had higher scores (p = .024) in knowledge. Intention was negatively correlated with knowledge (rs  = -.24, p < .01) and perceived behavioural control (rs  = -.16, p < .01). Male students (p = .031) and younger students had higher scores in intention (p = .040). Males had higher scores in subjective norms (p < .001), and older and senior students had higher scores in perceived behavioural control (p < .001).

CONCLUSIONS

Despite the current knowledge on COVID-19 available through multimedia-communication channels, students had negative perceived behavioural controls and intentions to care for COVID-19 patients. Formal education and training are required to enhance students' intentions to care for patients with infectious diseases. Additionally, demographics and belief variables influence students' intentions to care, and further in-depth analysis is required. Relevance to Clinical Practice This study suggests the importance of updating and contextualizing nursing and allied health curricula to meet global infectious disease guidelines and, ultimately, to support the healthcare system with efficient practitioners in future pandemics.

Willingness of dentists in the United Arab Emirates to perform restorative and surgical treatments for patients infected with hepatitis C

BACKGROUND

Dentists' refusal to treat patients infected with hepatitis C (HCV) continues to raise ethical concerns, particularly in countries where HCV is prevalent. The aim of this cross-sectional study was to assess dentists' willingness to treat patients infected with HCV and the socio-demographic variables that influence their decision.

METHODS

An online questionnaire was disseminated to dentists practicing in the United Arab Emirates (UAE) and enquired about their willingness to perform two dental treatments: restorative and surgical, to patients infected with HCV, while hypothetically being equipped with optimal personal protective equipment. Binary logistic regression test was used to assess socio-demographic factors that predict dentists' unwillingness decision.

RESULTS

Two-hundred and forty-five dentists participated in this survey. Among those, 25.6 and 19.3% were unwilling to perform dental extractions and aerosol-generating restorative dental treatments for patients infected with HCV, respectively. Dentists' clinical experience was a significant predictor of their unwillingness decision, with those of shorter clinical experience expressing greater reluctance than their counterparts (OR:1.61; 95% CI: 1.02-2.54; p = 0.042).

CONCLUSION

Patients infected with HCV who need dental care could face rejection by early career dentists, particularly if that treatment is a surgical one. Fresh dental graduates should be made aware of their ethical and legal responsibilities towards patients with infectious diseases, particularly HCV.

NLRP3 Inflammasome Expression in Gingival Crevicular Fluid of Patients with Periodontitis and Chronic Hepatitis C

The study is aimed at assessing the impact that periodontal disease and chronic hepatitis C could have on gingival crevicular fluid levels of the NLRP3 inflammasome, caspase-1 (CASP-1), and interleukin-18 (IL-18) and at evaluating whether the increased local inflammatory reaction with clinical periodontal consequences is correlated to their upregulation. Patients were divided into four groups, according to their periodontal status and previously diagnosed hepatitis C, as follows: (i) CHC group, chronic hepatitis C patients; (ii) P group, periodontal disease patients, systemically healthy; (iii) CHC + P group, patients suffering from both conditions; and (iv) H group, systemically and periodontally healthy controls. Gingival crevicular samples were collected for quantitative analysis of the NLRP3 inflammasome, CASP-1, and IL-18. CHC + P patients expressed the worse periodontal status and the highest NLRP3, CASP-1, and IL-18 levels, the difference being statistically significant (p < 0.05). The P group patients also expressed significantly more elevated NLRP3, CASP-1, and IL-18 levels, as compared to nonperiodontal patients (CHC and H groups). Chronic hepatitis C and periodontal disease could have a significant influence on the upregulation of NLRP3 inflammasome and its components, possibly contributing to an increased local inflammatory reaction and clinical periodontal consequences.

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.

Knowledge, attitude and behaviour regarding hepatitis C virus infection amongst Brazilian dental students

AIM

Dental health professionals, including dental students, are at high risk of exposure to infection with the hepatitis C virus (HCV) through occupational percutaneous injuries and eye exposure. Further, fear of HCV infection is associated with discriminatory attitudes. The current study aimed to evaluate the knowledge about HCV infection amongst dental students and their attitudes towards patients infected with HCV.

METHODS

A cross-sectional survey was conducted amongst 340 Brazilian dental students from two public universities using an instrument containing information regarding demographic characteristics, knowledge of HCV and attitudes towards patients with HCV infection. Descriptive statistics, Fisher's exact test, Student's t-tests, Mann-Whitney U-test and multiple logistic regression (MLR) were carried out (P < 0.05 was considered significant).

RESULTS

Response rate was 90% (n = 306), and more than half (54%, n = 165) of participants had high knowledge level (above the mean); 97.7% (n = 299) demonstrated positive attitudes. MLR showed that high knowledge of dental students regarding HCV was substantially influenced by advancement in year of study (last year; P < 0.001) and type of university (federal; P = 0.049). Positive attitude towards HCV-infected patients was mainly influenced by age (P = 0.004) and male gender (P = 0.022).

CONCLUSIONS

These results demonstrated a satisfactory knowledge about HCV infection amongst dental students, but some gaps were observed, suggesting the importance of continuous education about HCV in this population to prevent HCV infection as well as discrimination and prejudice towards patients with hepatitis C.

Arab dentists' refusal to treat HIV positive patients: a survey of recently graduated dentists from three Arab dental schools

OBJECTIVE

To assess intended refusal of recent graduates from three Arab dental schools to treat HIV + patients and factors associated with this intention.

MATERIALS AND METHODS

In 2015, convenience samples of recent dental graduates were included from Libya, Egypt and the United Arab Emirates. Participants responded to a questionnaire assessing personal background, knowledge of oral manifestations and fluids transmitting HIV, perceived adequacy of training and self-efficacy to manage blood exposures, attitude to risk of infection, moral beliefs and willingness to treat HIV + patients. Logistic regression assessed factors associated with intended refusal to treat HIV + patients.

RESULTS

The overall response rate was 552/710 (77.8%), mean age = 23.7 years with 41.8% males. The mean (SD) scores for knowledge of oral manifestations and fluids transmitting HIV were 5.5 (1.3)/8 and 4.2 (1.7)/7. The mean (SD) scores for attitude to risk of infection and moral beliefs were 2.9 (1.0)/4 and 2 (0.9)/3, respectively. One-third of respondents indicated intention to refuse treating HIV + patients. Knowledge of body fluids transmitting HIV and moral beliefs were associated with lower odds of refusing to treat HIV + patients (OR = 0.86 and 0.38) whereas attitude indicating greater concern for risk of infection was associated with higher odds (OR = 1.54).

CONCLUSIONS

One third of dentists from three Arab dental schools indicated they would refuse to treat HIV + patients. Adequate knowledge and moral beliefs reflecting professional ethics were associated with lower odds of refusal counterbalancing the association with attitude indicating increased concern for risk of infection with implications for dentist education and training.

Nursing Students' Willingness to Care for Human Immunodeficiency Virus-Infected Patients in the Future

Recent studies in various countries have shown controversy regarding students' willingness to care for human immunodeficiency virus (HIV)-infected patients as well as factors associated with students' decisions about this issue. This survey, based on the Theory of Planned Behavior, explored factors associated with Israeli nursing students' willingness to care for HIV-infected patients in the future. The results suggest that appropriate education and experience in caring for HIV-infected patients are critical for improving students' willingness to care for these patients.

Chinese dental students' knowledge and attitudes toward HIV/AIDS

Background/purpose

Oral care is vital to human immunodeficiency virus (HIV)-positive individuals. As future dentists, it is pertinent that dental students have sufficient knowledge and a positive approach toward this disease. The purpose of this study was to assess HIV/AIDS-related knowledge and attitudes among clinical dental students in central China.

Materials and methods

This survey was conducted on 103 dental students in the final year of a 5-year program. A structured questionnaire with 50 questions examining their knowledge under various categories and 17 questions examining their attitudes toward the disease was employed.

Results

The survey was completed by 92.2% (95/103) of the students. The results revealed that more than half of the respondents demonstrated a good level of knowledge, although few exhibited an excellent level. The mean scores on knowledge was 79.41 ± 6.3 out of a maximum possible score of 100, and there was no significant difference regarding sex. Despite their good level of knowledge, the majority (93.68%) displayed a negative attitude (nonprofessional attitude) toward HIV/AIDS.

Conclusion

These findings might help to define strategies to improve the quality of education among Chinese dental students and suggests that there is a need to address student misconceptions and attitudes toward the disease.

Herpes labialis and Nigerian dental health care providers: knowledge, attitudes, behaviors, and refusal to treat

Background

The few existing studies on herpes labialis among health care workers have been predominantly among non-dental health care workers. The purpose of this study was to determine Nigerian dental health care providers’ knowledge of, attitudes toward, preventive behaviors for, and refusal to treat patients with herpes labialis.

Methods

This cross-sectional study was conducted among final-year dental students at the University of Benin, dental house officers, and residents at the University of Benin Teaching Hospital, Benin City, Nigeria. Data collection was via a self-administered questionnaire. Bivariate statistics and logistic regression were used to relate the dependent and independent variables.

Results

Of the 120 questionnaires distributed, 110 were completed and returned, giving a 91.7 % retrieval rate. However, 15 of the returned questionnaires were discarded because they were improperly completed, leaving a total of 95 questionnaires for final analysis in this study. The majority of participants were over 28 years old (54.7 %), male (67.4 %), unmarried (66.3 %), and postgraduate dental health care providers (51.6 %). Less than half (43.2 %) of participants demonstrated adequate overall knowledge of herpes labialis. About one-tenth (10.5 %) and more than three-quarters (87.4 %) of participants reported a positive attitude and performance of adequate preventive behaviors, respectively. A total of 16.8 % of participants reported a high tendency to refuse treatment to patients with herpes labialis. Although not statistically significant, young, unmarried, male undergraduate participants reported a greater likelihood to refuse treatment to herpes labialis patients. We found a statistically significant positive correlation between attitude and refusal to treat patients with herpes labialis. However, marital status and the attitude of participants toward these patients emerged as the determinants for refusal to treat patients with herpes labialis.

Conclusions

Data from this study revealed a high level of inadequate knowledge, negative attitudes, and reasonably adequate preventive behaviors with respect to herpes labialis. One out of every six dental health care workers studied reported having refused to treat patients with herpes labialis. Unmarried dental health care providers and those with negative attitudes toward herpes labialis patients were more prone to refuse treatment to these patients.

Hepatitis B: knowledge, vaccine situation and seroconversion of dentistry students of a public university

BACKGROUND

Viral hepatitis B (VHB) is an occupational risk for dentists. It is necessary that dental students start clinical practice immunized with the vaccine, response monitored and informed about the means of transmission of the disease. Rarely, there are studies, which evaluate concomitantly knowledge of these academics and their vaccine situation.

OBJECTIVES

To evaluate the knowledge about Hepatitis B, the vaccine situation and the immunization status of dental students and to investigate the probable correlation between the status of immunization, vaccination membership and adherence to the test of seroconversion and associated factors.

PATIENTS AND METHODS

189 students from the dentistry course at the Federal University of Piaui (UFPI) who attended from the 3rd to 9th period were invited to participate in the research. Their knowledge about HBV, attitude regarding protection and their vaccine situation were assessed through a self-administered form. Antibodies against surface antigens of Hepatitis B virus (Anti-HBs) and against the antigens of the virus nucleous of Hepatitis B (Anti-HBc total) were measured qualitatively using the enzyme-linked immunosorbent assay (ELISA).

RESULTS

Of the 179 students surveyed, 58.1% knew about the degree of virulence of the Hepatitis B virus (HBV). As to the means of transmission, 98.3% considered blood transmission, 82.6% plates and cutlery, 15.6% cough and 12.3% vertical transmission. Most students (87.4%) knew that they should take 3 doses of the vaccine and 62.2% completed the immunization schedule. A minority of students (48.6%) knew the about the Anti-HBs test and 5.6% took the test. Among the students who reported having taken three doses of the vaccine, 12.5% were not seroconverted. There was no significant correlation between the variables.

CONCLUSIONS

Dental academics were unsure about the means of infection and prevention against HBV. Many of them had not completed the immunization scheme and did not have the test of seroconversion. The serological analysis revealed unprotection, even after students completed the vaccination schedule.
