The knowledge, attitudes and practices of doctors, pharmacists and nurses on antimicrobials, antimicrobial resistance and antimicrobial stewardship in South Africa.

BACKGROUND: Sustained injudicious and indiscriminate use of antimicrobials has exerted selection pressure for developing antimicrobial resistance (AMR), requiring behaviour change from healthcare professionals (HCPs) based on their knowledge, attitudes and practices (KAP) on antimicrobials, AMR and antimicrobial stewardship (AMS).
METHODS: A cross-sectional online questionnaire-based survey was conducted nationally amongst doctors, pharmacists and nurses from November 2017 to January 2018. The questionnaire comprised demographic information and KAP questions.
RESULTS: Respondents comprised of 1120 doctors, 744 pharmacists and 659 nurses. Antimicrobial resistance was considered a severe problem globally and nationally by majority of HCPs. Self-assessment of knowledge revealed gaps in understanding of antimicrobials, AMR and AMS. Confidence scores in prescribing by doctors, pharmacists and nurses were 57.82%, 32.88% and 45.28%, respectively. Doctors, 441 (45.2%) indicated no confidence in using combination therapy. Prescribing correctly showed a confidence level of 33.99% from 436 doctors, 41.88% from nine pharmacists and 35.23% from 107 nurses. Healthcare professionals (1600 [91.22%]) stated educational campaigns would combat AMR. Only 842 (40.13%) HCPs attended training on these topics and 1712 (81.60%) requesting more education and training.
CONCLUSION: This is the first comparative survey on KAP of practising doctors, pharmacists and nurses in South Africa. Doctors had the highest knowledge score followed by nurses and pharmacists. Practice scores did not corroborate knowledge and the higher attitude scores. Gaps in KAP were evident. Healthcare professionals indicated the need for more education and training, thus requiring a review of pre-service and in-service education and training in addition to continued professional development programmes for practising HCPs.

Introduction

The injudicious and irrational use of antimicrobials, vis-à-vis, incorrect clinical indication, dosing and administration, and, non-complaince of patients have been implicated in the development of antimicrobial resistance (AMR).[1] Antimicrobial resistance, an escalating threat globally, is of concern in human and animal health, the food industry and agriculture.[2] It adversely affects treatment, increases morbidity and mortality, results in extended hospital stays and necessitates more expensive, and often more toxic, treatment options.[3] According to best available data, an estimated 700 000 people worldwide die of resistant bacterial infections a year, and it is estimated that this may increase to 10 million people dying a year at a cost of 100 trillion USD by 2050.[4] Change lies in the hands of healthcare professionals (HCPs) responsible for the prescription, dispensing and administration of antimicrobial medicines to patients, namely doctors, pharmacists and nurses, respectively.

The Global Action Plan (GAP) on AMR addresses AMR through five strategic objectives. Of these, strategic objective 1 is increased awareness of AMR through effective communication, education and training.

This would be achieved by each member state implementing interventions to: (1) increase national awareness of AMR via programmes that target the different audiences in human health, animal health and the environment, (2) incorporate AMR as a core component in professional education, training and certification, (3) incorporate antimicrobial use and resistance into the school syllabus to improve understanding and further awareness with all information being accurate and relevant, (4) prioritise AMR as an important health issue requiring urgent action from all governmental departments and (5) create a multisectoral committee to address AMR from a One Health perspective.[2] Education for all HCPs on antimicrobial prescribing needs to begin at undergraduate levels, and should continue in post-graduation with specific training in using treatment guidelines.[5] The range of antimicrobial prescribers has been changing, with legislation allowing nurses, pharmacists and emergency care personnel to prescribe antimicrobials under certain conditions in South Africa (SA).[6,7,8] Healthcare professionals are responsible for managing antimicrobials, namely prescribing, dispensing and administering antimicrobials to patients. They must be knowledgeable and up-to-date on issues related to antimicrobials, AMR and antimicrobial stewardship (AMS). This study therefore ascertained the knowledge, attitudes and practices (KAP) of doctors, pharmacists and nurses in order to identify gaps for educational intervention.

Methods

Study design and population

A descriptive cross-sectional online survey was conducted nationally. Study sample included 15 111 (40.77%) pharmacists, including community-service pharmacists registered with the South African Pharmacy Council (SAPC). There were also 16 260 (43.87%) doctors and 5695 (15.36%) nurses, comprising of 5630 registered nurses and 65 enrolled nurses, who subscribed to Medpages, an SA database with contact information of HCPs in SA. The SAPC provided contact information of pharmacists and community-service pharmacists to the principal investigator, which was used to email the survey questionnaires. Medpages distributed the survey questionnaire to all doctors and nurses on their database. The study was undertaken from November 2017 to January 2018.

Survey instrument

The data were collected using a self-administered, web-based questionnaire with voluntary informed consent.

Questionnaire (Appendix 1) was adapted and piloted from a combination of questionnaires already available in literature.[9,10,11,12] Responses were anonymous. Questionnaire was divided into four sections and consisted of open-ended, closed-ended (yes or no) and Likert style questions (one of the following options: strongly agree, agree, neutral, disagree, strongly disagree).

The first section collected demographic, academic and professional data of the participants.

Second section consisted of questions that assessed the participants’ knowledge on antimicrobials, AMR and stewardship, contributing factors to AMR, sources of information and confidence in prescribing antimicrobials. Third section evaluated the participants’ attitudes and beliefs on antimicrobials, AMR and their contribution to AMR. Final section was practice-related and involved antimicrobial sensitivity-testing, empiric-prescribing, use of standard treatment guidelines (STGs), advice imparted to patients and prescribing for diagnosed medical conditions.

Statistical analysis

Dataset was analysed using IBM Statistical Package for the Social Sciences (IBM SPSS) version 25 (IBM Corp. Released 2018. IBM SPSS Statistics for Windows, Version 25.0. Armonk, NY: IBM Corp) using simple descriptive statistics to create frequencies and percentages. Continuous variables, such as ages, were described as mean ± standard deviation or median and compared using the Student’s t-test or Wilcoxon test as appropriate. Categorical variables, such as groups, were described as proportions and compared using Chi-square test or Fisher’s exact test as appropriate. The analysis of variance (ANOVA) statistical test was used to compare the KAP scores between the three professions, and the Bonferroni post-hoc test further described the pairwise statistically significant difference between the professions. For each factual question, a mark was allocated when the answer was correct. Other questions were assessed and given a mark for the most appropriate correct response. Responses for ‘strongly agree’ and ‘agree’ were combined as well as for ‘disagree’ and ‘strongly disagree’. The study population had declined from Section 1–4 of the questionnaire, thus completed sections were analysed separately. Partially completed questionnaires were also considered, hence the different ‘n’ values per section. The South African STGs were used to assess doctors and nurses’ choices of antimicrobial treatment for given medical conditions and the primary care drug treatment (PCDT) list was used to assess pharmacists’ choice of antimicrobial treatment in Section 4 of the questionnaire.

Ethical considerations

Ethical approval was obtained from the Humanities and Social Sciences Research Ethics Committee of University of KwaZulu-Natal (HSS/0868/017M) prior to the study.

Results

Total number of respondents in this study was 2523 (6.81%) HCPs, consisting of 1120 doctors, 744 pharmacists and 659 nurses with response rates of 6.89%, 4.92% and 11.57%, respectively. There were 1520 (60.25%) females and 1003 (39.75%) males. The modal-age groups were 31–40 years (30.71%) for doctors, 21–30 years (30.24%) for pharmacists and 51–60 years (36.87%) for nurses. Amongst nurses, 392 (59.48%) possessed a diploma qualification. A greater proportion of HCPs, that is 1843 (73.05%), occupied jobs in urban areas whilst the number for those in rural areas was 306 (12.13%). Most HCPs, 1205 (47.76%), worked in private practice and 792 (31.39%) worked in public (Appendix 1).

Knowledge

Awareness of antimicrobial resistance

The majority of HCPs (93.37%) perceived AMR to be a serious problem globally (Table 1). Using a one-way ANOVA, there were statistically significant differences in the appreciation of the problem of AMR between the different professions (p = 0.002) with nurses being least aware. Similar numbers of HCPs agreed it was a national problem. However, much lower number of HCPs (73.77%) agreed AMR was a serious problem in their hospital or practice and there was a statistically significant difference between them (p = 0.011).

Assessment of knowledge on antimicrobials, antimicrobial resistance and antimicrobial stewardship

The self-assessment of knowledge indicated that 791 (37.70%) HCPs were 75% confident of their knowledge on all three topics with 349 (16.6%) HCPs showing 100% confidence (Figure 1). Notably, a greater percentage of nurses (52.40%; 261) had ≤ 50% confidence levels on knowledge of all three topics as compared to pharmacists (45.3%; 283) and doctors (39.3%; 383). Using the ANOVA test, there were statistically significant differences in confidence levels of knowledge on antimicrobials, AMR and AMS between doctors, pharmacists and nurses (p = 0.0001, 0.00001 and 0.009, respectively). A Bonferroni post-hoc test indicated that doctors were different from nurses and pharmacists were different from nurses, however doctors and pharmacists were not statistically different.

Varying numbers of HCPs correctly stated antimicrobials were not effective in treating acute viral infections (p = 0.000), and a majority of HCPs correctly stated common colds are caused by viruses (Table 1).

Contributory factors towards antimicrobial resistance

Healthcare professionals identified the overuse of antimicrobials by prescriptions (1922; 91.61%), patient pressure for antimicrobial prescriptions (1579; 75.26%) and non-adherence of patients to prescribed treatment (1537; 73.26%) as most contributory towards AMR, as depicted in Figure 2. The least contributory was the lack of immunisation campaigns (262; 12.49%). Statistically significant differences (p < 0.05) were noted between the three groups of HCPs in seven of the nine contributing factors.

Selection of contributory factors resulting in antimicrobial resistance.

Confidence in prescribing antimicrobials

Self-assessment on confidence in 10 aspects of prescribing antimicrobials showed 587 (60.21%) doctors were confident in 7 (70%) aspects. No confidence was reported by 433 (44.40%) doctors about using combination therapy when necessary, about when to stop or streamline therapy according to clinical evaluations and investigations and about making decision not to prescribe antimicrobials when there’s fever with no serious criteria (Table 2). A total of 244 (48.93%) nurses stated confidence in six (60%) aspects, and overall 117 (23.50%) nurses stated no confidence in prescribing antimicrobials. Only 206 (33.88%) pharmacists were confident in all aspects of prescribing with 156 (25%) stating no confidence when prescribing antimicrobials. The confidence level of pharmacists and nurses can be gauged from the fact that 221 (35.38%) pharmacists and 116 (23.44%) nurses selected ‘not applicable’ to prescribing antimicrobials. Statistically significant differences (p < 0.05) were noted between the three groups of HCPs in eight aspects of prescribing.

, Prescribing antimicrobials represented as a percentage.

ANNOVA, analysis of variance.

The most preferred sources of information on appropriate use of antimicrobials for doctors were STGs (706; 72.5%) followed by South African Medicines Formulary (SAMF) (579; 59.4%). The pharmacists preferred the SAMF (453; 72.5%) and STGs (426; 68.2%), whilst nurses used STGs (343; 68.9%) and indicated equal usage of the SAMF and WHO guidelines (277; 55.6%).

A majority (1972; 93.99%) of HCPs agreed that there were risks associated with the irrational use of antimicrobials, most noted risks being AMR (1729; 82.41%), side effects (675; 32.17%) and adverse drug reactions (486; 23.16%). Only 842 (40.13%) HCPs had attended any workshops or training on antimicrobials and AMS.

A total of 1712 (81.60%) HCPs requested more education and training on antimicrobial use, AMR and AMS.

There was a statistically significant difference in total knowledge of antimicrobials, AMR and AMS between the three groups of HCPs. Using the Bonferroni post-hoc tests, it was observed that doctors scored significantly higher than both the pharmacists and nurses (p < 0.05), with the knowledge scores being 65.74%, 60.07% and 60.14%, respectively.

Attitudes

Doctors (551; 64.1%), pharmacists (354; 68.7%) and nurses (249; 65.5%) disagreed that antimicrobials were safe drugs that could be commonly prescribed. Majority (1689; 96.29%) agreed that prescribing antimicrobials to patients who did not really need them, would ultimately have a negative impact on their health.

Strategies to combat antimicrobial resistance

The most important strategies the HCPs believed would aid in combatting AMR were educational campaigns (1600; 91.22%), use of therapeutic guidelines (1486; 84.72%) and improved infection control (1163; 66.31%). Vaccination campaigns (543; 30.96%) were surprisingly reported to be least important. Statistically significant differences (p < 0.05) were observed for two strategies (Figure 3).

FIGURE 3

Attitudes on strategies that would combat antimicrobial resistance.

Varying numbers of HCPs – 600 (69.8%) doctors, 414 (80.4%) pharmacists and 323 (85.0%) nurses – believed skipping or missing a dose or two of antimicrobials contributed to the development of AMR and this difference was statistically significant (p = 0.000). A total of 545 (63.4%) doctors, 221 (42.9%) pharmacists and 126 (33.2%) nurses believed they personally contributed towards AMR in some form (p = 0.000).

With respect to attitude towards antimicrobials, AMR and AMS, using a one-way ANOVA, there was a statistically significant difference between doctors, pharmacists and nurses with attitude scores of 68.71%, 68.59% and 65.94%, respectively (p = 0.013). Using the Bonferroni post-hoc analysis, doctors and pharmacists scored statistically higher than nurses (p = 0.014).

Practices

Prescribing antimicrobials

Only 22 (4.43%) pharmacists possessed Section 22A (15) permit, which allowed them to prescribe for PCDT, of which only 16 (3.22%) pharmacists prescribed antimicrobial drugs. Almost a third of nurses (126; 34.00%) possessed the concession permit in terms of Section 22A (12) of the Medicines and Substances Control Act of 1965 and Section 38A of the Nursing Act of 1978, which allowed nurses to prescribe medicines. However, only 75 (20.22%) prescribed antimicrobial drugs. In this study, 82 (16.50%) pharmacists and 33 (8.89%) nurses prescribed antimicrobials without a licence. Majority of antimicrobials were prescribed by doctors.

Antimicrobial stewardship

Six hundred and seventy-eight (80.52%) doctors, 19 (3.82%) pharmacists and 61 (16.44%) nurses prescribed antimicrobials empirically (p = 0.000). Four hundred and forty-one (52.38%) doctors, seven (1.41%) pharmacists and 83 (22.37%) nurses sent samples for microbiology testing before initiating antimicrobials. Only 496 (58.90%) doctors, 349 (70.22%) pharmacists and 185 (49.87%) nurses possessed the latest South African STGs (p = 0.000). However, only 197 (23.40%) doctors, 42 (8.45%) pharmacists and 66 (17.79%) nurses always used the STGs (p = 0.000).

Advice imparted to patients on antimicrobial use is reported in Figure 4. On the safe use of antimicrobials, 309 (83.29%) nurses gave the most correct advice, followed by 404 (81.29%) pharmacists and 630 (74.82%) doctors (p < 0.00).

FIGURE 4

Advice imparted by healthcare professionals to patients on antimicrobial use.

Based on a range of practice scores, between 0 (poor) and 100 (best practice), average scores for doctors, pharmacists and nurses were 57.68% ± 16.42%, 43.14% ± 16.53% and 54% ± 14.34%, respectively. Using an ANOVA test, practice scores for the three groups of HCPs were statistically significantly different (p < 0.05).

Selection of appropriate antimicrobial treatment

There was a higher percentage of appropriate treatment (41.88%) provided by nine pharmacists compared to 33.99% from 436 doctors and 35.23% from 107 nurses. However, there were fewer pharmacists who were eligible to provide treatment for the given conditions. It must be noted only 1.87% of nurses provided the correct strength, interval and duration for treatment.

Discussion

To our knowledge, this is the largest national study ascertaining KAP on antimicrobials, AMR and AMS amongst prescribers, dispensers and administrators of antimicrobial medicines to patients. This is the first KAP study amongst doctors, pharmacists and nurses in SA using the same tool and it provides valuable insights and information on strengths and weaknesses of KAP amongst HCPs and indicates areas where interventions are required.

Antimicrobial resistance is an increasingly serious public health threat.[13] Awareness of AMR is the first step in addressing and reducing this global problem.[2] We found that majority of HCPs in SA have been sensitised to AMR as a national and global concern, with doctors having most awareness followed by pharmacists and then nurses who had the least conceptual awareness. However, as a group, HCPs’ awareness of AMR was comparable to a study by Burger et al. (2016), in which final year pharmacy students in SA reported 97.7% awareness to AMR as a global problem.[14] Our HCPs’ national awareness of AMR was similar to the studies by Vaillant et al. (2019), where French HCPs reported 93% national awareness of AMR, and Farley et al. (2018), where 95.8% of primary care prescribers in SA stated AMR was a national problem.[15,16]

The appreciation of the problem of AMR in context of their own work showed there was a much lower awareness of AMR in their hospitals or practices. This being stated, our findings showed higher awareness at practice level compared to the study by Vaillant et al. (2019), who reported 51.5% of French HCPs had awareness of AMR at practice level.[15] Our research findings with respect to AMR awareness amongst HCPs are similar to Wasserman et al. (2017), who reported that 87% of final year medical students in SA agreed AMR was a global problem and only 61% saw it as a problem in their practice.[17] Similar results were reported in other studies by Pulcini et al. (2010), where there was 95% national awareness with 63% local awareness for AMR by junior doctors, and Garcia et al. (2011), who reported 97% global and national awareness with 73% local awareness by prescribing doctors.[9,18] However, our local awareness results contrasted with the study by Salsgiver et al. (2018) where it was reported that majority (89%) of prescribers in the United States agreed AMR was a problem at their hospitals and prescribers actively supported AMS programmes at all hospitals.[19]

Based on their self-assessment, only 16.6% of HCPs were 100% confident in their knowledge of antimicrobials, AMR and AMS. The percentage of HCPs that had 75% confidence in their knowledge of antimicrobials and AMR, respectively, was 43% and 37%. This is in contrast to the report by Dall (2019) whereby 80% of HCPs from 30 European countries stated they possessed sufficient knowledge on correct antimicrobial use and 96% stated having knowledge of AMR.[20] Several aspects must be comprehensively considered when prescribing antimicrobials and complete confidence in each aspect is essential in achieving positive patient outcomes. In this study, diminished levels of confidence in the 10 aspects of prescribing antimicrobials were observed, with 587 (60.21%) doctors confident in only seven aspects. A third of pharmacists stated confidence in all aspects whilst almost a quarter of the nurses were not confident in prescribing. Wasserman et al. (2017) reported that only a third of the students were confident in prescribing.[17] Our results are also similar to findings by Pulcini et al. (2010), where it was found junior doctors in France and Scotland shared similar overall confidence (57.61%) in prescribing antimicrobials to that of our doctors (57.82%).[9]

Forty per cent of HCPs had attended or received training on antimicrobials and AMS with majority (81.61%) indicating a need for more education and training. Our research findings are similar to those reported by Burger et al. (2016) whereby only 37.75% of pharmacy students had training on AMS and 90% needed more training.[14] This was confirmed by Farley et al. (2018) where numerous prescribers requested more education on appropriate antimicrobial use and in Wasserman et al. (2017) where medical students wanted more education to aid in antibiotic prescribing.[16,17] On the safe use of antimicrobials, close to two-thirds of HCPs indicated an awareness that in general antimicrobials are safe, however continuous use without due regard can have undesired effects. Majority of HCPs indicated that there could be negative effects on patients if antimicrobials were unnecessarily prescribed. The latter finding was supported by Burger et al. (2016).[14]

Numerous contributing factors result in AMR. In this study, the leading causes identified by majority of HCPs were: over-prescription of antimicrobials, patients’ non-adherence to treatment and patient pressure for antimicrobial treatment. Burger et al. (2016) similarly reported widespread and overuse of antimicrobials (94.2%) and poor patient adherence to medication (89.5%) as contributing to AMR.[14] A similar observation was made by Wasserman et al. (2017), who reported inappropriate use of antimicrobials (> 95%) as the primary cause of AMR.[17]. Similar findings were also reported in other studies by Pulcini et al. (2010) in France and Scotland, where > 90% of the junior doctors selected over-prescription of antimicrobials as being causative; Abera et al. (2014) in Ethiopia, where the nurse prescribers and doctors stated poor patient adherence (86%) and overuse of antimicrobials (80.5%) were responsible for AMR; and Dyar et al. (2014) in Europe, where final year medical students reported over-prescription of antimicrobials (> 95%) resulted in AMR.[9,10,21]

According to our research, the most appropriate resources for antimicrobial selections were STGs, SAMF and international guidelines, respectively. This is in contrast to Wasserman et al. (2017) who reported that medical textbooks (87%), registrars (85%) and consultants (83%) were most common learning resources.[17] The important strategies chosen for combatting AMR by majority of HCPs were educational campaigns (91.22%) and usage of therapeutic guidelines (84.72%). This finding was similar to Burger et al. (2016) who reported that education on antimicrobial therapy (92.3%), antimicrobial usage policies (86.9%) and development of treatment guidelines (86.2%) would combat AMR.[14] Interestingly only 60.2% of HCPs were in possession of the latest South African STGs and only 17.8% always used it.

Attitude scores amongst all professions were slightly higher than knowledge scores and practice scores were the lowest. The doctors and pharmacists indicated higher attitude scores than nurses. Doctors obtained the highest knowledge scores. Practice scores did not corroborate the self-proclaimed knowledge and attitude scores.

Limitations

Gatekeeper permission to contact the HCPs proved problematic. The Protection of Personal Information Act (POPI) precluded access to the databases of the Health Professions Council of SA. The SA Nursing Council and Forum of University Nursing Deans of SA could not assist. The survey was conducted from November 2017 to January 2018, which is a festive period in SA, resulted in reduced participation from professionals.

Participation was voluntary, and, combined with the above constraints; the response rate was relatively poor.

The results should thus be extrapolated to the wider HCP community with caution. Not all the questionnaires were fully completed resulting in different ‘n’ values for different sections.

Conclusion

This is the first comparative survey on KAP of practising doctors, pharmacists and nurses in SA. Doctors had the highest knowledge score followed by nurses and pharmacists, respectively. Practice scores did not corroborate knowledge and the higher attitude scores.

Self-assessment of knowledge showed that marginally more than half (< 55%) of HCPs were ≥ 75% confident in their knowledge on these topics. Confidence on prescribing antimicrobials showed that < 60% of doctors were confident in prescribing antimicrobials, with the confidence level even further reduced for pharmacists and nurses. Confidence in prescribing the correct treatment for given conditions ranged between 34% and 42% for the HCPs. Gaps in KAP were thus evident. Healthcare professionals indicated the need for more education and training, thus requiring a review of pre-service and in-service education and training in addition to CPD programmes for practising HCPs. It is recommended that both higher education institutions offering medical, pharmacy and nursing degrees as well as professional bodies regulating this education should map and update their existing curricula and scopes of practice, respectively, against the World Health Organization’s competency framework and associated curriculum for healthcare workers’ education and training on AMR.[22]
