Four conceptual themes emerged during the analysis of the healthcare workers’ individual interview transcripts: 1) Conceptions in relation to the prescriber, 2) Conceptions in relation to the mother and child, 3) Conceptions in relation to other healthcare actors, and 4) Conceptions in relation to outcome, with associated categories (Table 2). An overview of how the themes are interrelated is shown in Figure 1.
1. Theme: Conceptions in relation to the prescriber
The first theme contains conceptions related to the prescriber’s own internal process and how much room for manoeuvre there was when prescribing antibiotics for children under the age of five. The theme consists of the following three categories: Executing clinical investigation, Utilising structural support and Treating what is not known.
1.1 Category: Executing clinical investigation
This category covers conceptions related to the healthcare workers’ basis for deciding when they do or do not prescribe antibiotics for children. The participants emphasised that a thorough physical examination and medical history provided by the mother was often sufficient to determine the need for antibiotics.
“When I get a patient coughing, I examine. Maybe he/she has a common cold or upper respiratory tract infection that are caused by viral infection, I don’t treat with antibiotics. Indications like productive cough with yellowish sputum, chest tightness and nasal flaring indicate that the child has severe pneumonia so this leads me to a conclusion that the patient needs antibiotics.” (Healthcare Worker (HW) 20)
In some statements, healthcare workers indicated that they used laboratory tests such as complete blood count, rapid diagnostic tests for malaria and urine dip-stick based on availability at the clinic or external laboratories. However, the clinician tended to lean towards their previous, clinical experience when the results were conflicting. “(…) many times, bacterial infection does not depend on lab investigation. What I have taught myself is about the signs and the presentation of the mother.” (HW 16)
The healthcare workers thus agreed that the physical examination and medical history of the child were their most important tool for antibiotic decision-making. The extent to which they used laboratory investigation varied according to availability but this was of secondary importance.
1.2 Category: Utilising structural support
The second category comprises conceptions of the structural support the healthcare workers made use of that affected their prescribing habits. These include the use of guidelines, collegial support and continuous education. According to the participants, guidelines such as WHO’s Integrated Management of Childhood Illness (IMCI), are a trustworthy tool for deciding which antibiotics to choose for a certain condition or disease.
“Most of the times we use the WHO (…) Integrated Management of Childhood Illness in categorizing children diseases. So, from these guidelines we get the directives for prescribing antibiotics to children under 5 years.” (HW 1)
Statements from healthcare worker’s in larger facilities described a practice of consulting colleagues with higher education or discussing difficult cases at internal meetings. Continuous education and external seminars were valued by the participants for increasing knowledge and correcting malpractice, but also for creating a sense of belonging.
“Sometimes we prescribe underdoses as I mentioned in the first case(…) [therefore] we need to be people who read a lot/keep updated. For example, every Thursday there are meetings at [a referral hospital] where they invite people from different centres where they share/teach so you learn, you get exposure and feel you belong to each other, which is very useful.” (HW 8)
Some healthcare workers requested more training on antibiotic resistance and others stated that previous training has, in fact, affected prescribing practices. “Previously we used to give medicine to children without investigations. But after I went for further studies, I realized that not all children are to be given antibiotics.” (HW 15)
In summary, guidelines such as the IMCI are a trusted tool for antibiotic prescription for children and the healthcare workers had a positive view of collegial, continuous education as a means of gaining support and new knowledge.
1.3 Category: Treating what is not known
Statements in the third category revealed a variation in terms of how the healthcare workers have dealt with uncertainty when diagnosing and treating children. Some statements highlight that clinicians were comfortable with giving advice for symptomatic treatment after having ruled out severe disease or specific diagnoses requiring antimicrobial treatment. “One child presented with flu and high fever, but on examination for chest tightness or drowsiness I found no problem. I advised the mother to give black tea and lemon and the child recovered.” (HW 1) Other healthcare workers tended to prescribe antibiotics for children with fever without focus and/or negative laboratory results on the basis of their previous experience, as shown in the following statement:
“Other times I give antibiotics even if there are no positive results from the lab investigations, since the child had other signs/symptoms of other diseases. I treat in this way because I cannot send home a child who comes to me with high fever without giving any treatment.” (HW 10)
At times, the primary health clinicians have come across children who they perceived as being severely ill, requiring urgent management. In this case, statements show that children may be given antibiotic treatment before the diagnoses are being established, and some are subsequently admitted or referred to a higher-level facility.
“(…) for example, if the child comes with high fever and convulsions you cannot know if it is malaria or septicaemia, so here, I will give a combination of drugs or antibiotics while waiting for the test results for malaria.” (HW 16)
When dealing with uncertain cases of childhood infections, perceived severity of illness is an important factor when determining the need for antibiotics. However, for children without apparent need for antibiotics, statements indicate that the healthcare workers had different strategies depending on their self-confidence in giving advice for non-antibiotic treatment.
2. Theme: Conceptions in relation to the mother and child
The second theme comprises conceptions of the social and relational aspects of the mother and child. This theme consists of the following three categories, namely Antibiotic misuse is common practice, Use of local remedies are less of a concern and Low-income affects healthcare seeking behaviour and treatment.
2.1 Category: Antibiotic misuse is common practice
Statements in this category revealed that healthcare workers frequently come across misuse of antibiotics in children. Many healthcare workers are approached by mothers expecting a prescription for antibiotics for their child or have encountered children in whom antibiotic treatment had been initiated at home. Non-compliance to treatment, such as not finishing the course of treatment or not adhering to time intervals for administration, was said to be common.
“In fact, the main challenge is the children not completing the doses. The parent can be instructed to give the dose for 5 days but they only give it for 3 days when they see improvements to the child health, but after a certain period the child suffers the very same problem.” (HW 19)
The statements show how the healthcare workers have handled these challenges, which for some have been a cause of frustration.
“(…) there are challenges. For example, a mother can tell you that ‘my child is [not] cured without an injection’. Based on my experience, other times the child does not need medication. But when I try to explain it is a challenge! Others may think you don’t like them (Humpendi), or I am a stingy person (Mchoyo) in [not] giving the medication, but we prescribe medicine based on the guidelines!” (HW 3)
However, most clinicians emphasised the need for good consultation to promote appropriate antibiotic use, as the mothers may otherwise not adhere to the treatment, re-attend or buy antibiotics directly from the pharmacy.
“For instance, a parent can request you to prescribe Septrin as he/she believes it can cure the child. Mostly we prescribe medications after doing a thorough clinical assessment, investigations and proper counselling to the mother after establishing the diagnosis. Most parents tend to understand and are satisfied when they are counselled well.” (HW 19)
In conclusion, the statements show that misuse of antibiotics and expectations of antibiotic prescription for Tanzanian children constitute a common challenge to primary healthcare workers. Many expressed the need for educating the mothers on rational antibiotic use, meanwhile, some have tried to execute this time- and energy-consuming task in their daily, clinical practice.
2.2. Use of local remedies are less of a concern
While not present in all the interviews, statements reveal that the healthcare workers have sometimes come across mothers who had used local remedies, such as herbal medication or bicarbonate soda, in the children. This was generally less of a concern for them:
“If they [the mothers]have used traditional medicine (dawa) and they didn’t give the child infection or any reaction (…) I will give this child a dose of medication (…). Because traditional herbal medicines (mitishamba) are only leaves and I don’t think they affect the child negatively.” (HW 16)
Thus, some did not perceive any negative effects of traditional, herbal medicine, whilst others have been discouraging the use of these: “There are some who tell us they are using local herbal medications (mitishamba), and we discourage the use of these because they do not have any standards (hazina viwango vyovyote).” (HW 20)
2.3 Category: Low-income affects healthcare seeking behaviour and treatment
According to the statements in the third category, the social status of the mother and child affected healthcare seeking behaviour and, consequently, the use of antibiotics. Some healthcare workers at private facilities recognised that low-income families, due to financial constraints, were more likely to buy antibiotics for their children straight from the pharmacy, without first attending the health facility:
“(…) when a low-income family comes to the health facility (hospitali) there are charges like consultation fee, laboratory investigations fee. So, they skip that and go to the pharmacies and explain what is their problem and they buy [antibiotics].” (HW 8)
Further, according to the statements lack of money may also force families attending private healthcare to buy only a portion of the recommended course of antibiotics. It was obvious that few healthcare workers at public facilities had also taken the financial situation into account when managing a child in need of antibiotics. “For instance, in patients with financial constraints we normally prescribe on the basis of what is available in the facility.” (HW 6) Children from low-income families may thus more often have been treated with antibiotics chosen on the basis of availability or cost, rather than what was most eligible for the condition.
In some of the statements it was mentioned that financial constraints may also present a barrier to the use of laboratory tests, as these were often performed at external laboratories. “Sometimes there are complications and we ask them to have laboratory investigations done. Those who can afford to pay goes for that.” (HW 3) According to the data, social status is thus one of the determinants of antibiotic use in Tanzanian children due to occurrent costs or resource limitations at the health facility, laboratory or pharmacy.
3. Theme: Conceptions in relation to other healthcare actors
The third theme deals with conceptions in relation to other healthcare actors, namely, how they affect the quality, availability and use of antibiotics. The three categories are: Health ministries and drug companies are accountable, Pharmacies facilitate availability without prescription and Some healthcare providers are dubious.
3.1 Category: Health ministries and drug companies are accountable
This category covers conceptions of health ministries and drug companies’ responsibility in providing adequate antibiotics in terms of quality, range and quantity. At first, statements in this category revealed a concern about the quality of the available antibiotics:
“To the drugs manufacturing companies, I say that they have to consider the issue of humanity! They have to produce medicines that have qualities. Most of the medicine are of a very low quality/standard. They don’t treat as we expect.” (HW 12)
Thus, the quality of drugs was perceived as the liability of the manufacturing companies and this should be dealt with by the Tanzanian authorities, according to the following statement:
“The government should make a policy [of control]. One particular medicine that enters the country today and one that will be imported after one year look the same, but they have different qualities.” (HW 17)
Secondly, some healthcare workers in public facilities experienced problems with receiving an adequate range and quantity of antibiotics from the governmental Medical Stores Department. This limited their choices in terms of antibiotic prescription which, according to some participants, may lead to antibiotic resistance. “Another major problem that can cause antibiotic resistance is limited antibiotic stock. We need an adequate stock in our facility.” (HW 6)
In summary, some healthcare workers were concerned that certain antibiotics available in Tanzania were of poor quality and called for increased control by the health ministry. According to the statements, limited range of antibiotics may affect antibiotic resistance.
3.2 Category: Pharmacies facilitate availability without prescription
The second category contains conceptions of the relationship between the healthcare worker and the pharmacies. According to the statements, pharmacies frequently sell antibiotics without a prescription, which may lead to irrational use of the antibiotics.
“We have parents like this, they (…) went to pharmacy and were given medicine but there was no improvement to the child. I have a look at the medicine, I assess the child to rule out what the problem is, and we found that the child was receiving wrong treatment! (…) I advise them not to start in the pharmacies when the child is sick. They have to come to the hospital; I prescribe, then they can go and buy in the pharmacies.” (HW 20)
On the contrary, few statements recognized prescription by pharmacists as a positive means of decreasing the work load of the health facilities. “The stores [pharmacies] are so useful that we were not able to do all tasks alone in the health facilities. I advise if people that, if see the problem is big, they have to go to the health facility (hospitali).” (HW 8)
Nevertheless, most healthcare workers perceived the common practice of pharmacies in selling antibiotics without a prescription as problematic, leading to irrational use of antibiotics in Tanzanian children.
3.3 Category: Some healthcare providers are dubious
The third category covers statements relating to the healthcare workers’ concerns about the management and treatment of children at other clinics. Some less well-equipped or rural facilities are perceived to be lacking in diagnostic accuracy.
“(…) many times there is a problem in the dispensaries and rural hospitals and many times they do not get to the investigation. They rush to give antibiotics to the children trying to save them but the child guidelines [IMCI] will help to know if the child should be given antibiotics or should be tested further.” (HW 16)
Private facilities, on the other hand, may be driven by profit as shown in the following statement:
“I have worked in many private clinics where the patients come and buy half a dose, and I tell them that it can bring problems to them. For example, they want to buy only 15 amoxicillin tabs [half a dose], but because our boss wants income we have to give the medication.” (HW 3)
Notably, both these two examples of perceived dubious management may lead to the irrational use of antibiotics, according to the participants.
4. Theme: Conceptions in relation to outcome
The fourth conceptual theme involves conceptions of treatment outcome when prescribing or choosing not to prescribe antibiotics to children. The theme consists of three categories: Success is the norm, Challenges are complex and Antibiotic resistance is partly acknowledged.
4.1 Category: Success is the norm
Statements in this category revealed that, overall the healthcare workers had positive experiences when treating children with antibiotics. Some also had positive experiences of when they chose to not prescribe antibiotics in cases of perceived dehydration fever in neonates, teething or common colds.
“I have met many children with upper respiratory infection and I give antibiotics based on the guidelines, and I have never met a child coming back to me with the same problem. I have experience of not giving antibiotics to neonates for a long time. Most of the time neonates suffer dehydration fever and I encourage the mothers to breastfeed and they recover.” (HW 1)
Several statements showed that mothers were instructed to come back to the clinic if the child did not improve. If the mother did not return, the healthcare workers interpreted this as a sign of treatment success. “Once we prescribe medication, we tell them to come back if the condition worsens. Many don’t come back and this gives us a feedback of a positive effect of the medicine given.” (HW 3)
In general, children treated with or without antibiotics after assessment by the primary healthcare workers recovered well. If they visited the clinic again this was mainly due to a new condition or disease, according to the statements.
4.2 Category: Challenges are complex
Participants identified a wide variety of challenges perceived to have an adverse effect on treatment outcome. These statements included non-compliance to treatment, self-prescription, misdiagnosing, drug resistance and lack of resources. In response to this, the healthcare worker may perhaps have changed treatment or referred the child to a higher-level facility.
“This [treatment failure] happens in relation to [work] resources (…) As a doctor one has to fight in all ways possible to do the job because there are times drugs become resistant or there is a misdiagnosis and you have to look for an alternative or make a referral if the patient doesn’t get well; they will be required to go to a higher-level hospital; you cannot do everything right.” (HW 16)
A common challenge for the healthcare workers was the lack of adherence to antibiotic administration in children treated at home, which according to some was a reason for treatment failure in the children. Others attributed disease re-occurrence to the effects of the cold season. “At our centre there comes situations where the child comes with the same problem and this is mainly noted during dusty or cold seasons when children cough a lot.” (HW 10)
In summary, the challenges facing primary healthcare workers in Tanzania when prescribing antibiotics to children were complex according to the statements. There were multiple causes of adverse outcomes including non-compliance with treatment.
4.3 Category: Antibiotic resistance is partly acknowledged
This category comprises conceptions of antibiotic resistance, including statements relating to perceived mechanisms of antibiotic resistance and to whom this conveyed a challenge. Most healthcare workers were aware of the issue of antibiotic resistance, but few experienced it as a problem in daily practice. “I have never come across that [antibiotic resistance]. We are in the primary level [in the healthcare system] so it is very difficult to notice that.” (HW 1)
Whilst some statements showed no conception of the mechanism of antibiotic resistance, the remaining statements portrayed three main explanations for the development of resistance. The first was related to ‘the pathogen’: “This [antibiotic resistance] is when a pathogen or bacteria adapts to a certain medicine, when given in small amount that cannot kill it. When the pathogen/bacteria rise up again strongly and the medicine cannot help/treat anymore you have to do loading or change the medicine.” (HW 3)
The second conception was related to ‘the disease’: “Drug resistance is when a patient is given medicine and gets cured, and when he is ill again, he is treated with the same medicine and finally the disease becomes resistant to that medicine.” (HW 7)
The third conception concerned the mechanism of antibiotic resistance related to ‘the body’: “The way I understand [antibiotic resistance], is when a person uses many medicines to treat one condition. So, when a drug is used it can no longer treat because the body gets used to the drug.” (HW 4) However, a common thread between these three conceptions was that individual misuse of antibiotics could drive the development of resistance and consequent treatment failure in that same individual. Meanwhile, few healthcare workers reflected on how misinterpretation of the IMCI guidelines has affected prescription of amoxicillin and thus may contribute to resistance as shown in the following statement:
“This [antibiotic resistance] can come about when the medication is used irrationally or if the same drug is used for a long time (…) for example these drugs, amoxicillin, came in 1999 in the training of the IMCI. It was one of the recommended drugs and thus was used a lot [literally] every patient who came was given this drug to make them happy but right now this drug does not work well.” (HW 16)
In summary, most healthcare workers perceived antibiotic resistance as a problem for the individual who has been misusing antibiotics. However, few reflected on the issue in relation to its effect on public health.
