ABSTRACT

BACKGROUND. Diarrhoeal disease (DD) is a major cause of childhood mortality in developing countries. In South Africa (SA), it ranks as one of the top five causes of under-5 mortality. Local and global guidelines on the management of acute DD are readily available. The Standard Treatment Guidelines (STGs) and Essential Drugs List for Hospital Level Paediatrics are a recognised standard of care for children in SA hospitals. However, children still die from this preventable disease.
OBJECTIVE. To determine whether doctors adhered to standard treatment guidelines when treating children under 5 years of age presenting to Edendale Hospital in Pietermaritzburg, KwaZulu-Natal Province, with acute DD.
METHODS. The study was a retrospective clinical audit of individual patient records.
RESULTS. One hundred and thirty-five patient records were reviewed. Forty-seven percent had a correct nutritional assessment, 41% were correctly assessed for shock and 27% for dehydration. Appropriate investigations were undertaken in 12%. Ninety-seven percent of patients had appropriate fluid plans prescribed. Zinc was prescribed in only 39% of patients, whereas 84% were appropriately not prescribed antibiotics and no patients received anti-diarrhoeal medication. In 90% of patients, the correct post-care patient referral was made, and 47% of caregivers were adequately advised about ongoing care of their children.
CONCLUSION. This study identifies substantial non-adherence to the SA STGs for the management of young children with acute DD.


 

 

The fourth Millennium Development Goal (MDG 4) committed participating countries to reduce the under-5 mortality rate (U5 MR) by two-thirds between 1990 and 2015.[1] South Africa (SA) made insufficient progress of achieving the MDG 4 U5 MR target of 21 per 1 000 live births by 2015.[2] From 1990 to 2005, SA's rate of progress was lower than conflict-ridden countries such as Somalia, Iraq and the Democratic Republic of Congo. However, from the middle of the last decade, SA's U5 MR has declined significantly, and between 2006 and 2011, the annual rate of decline was the fourth fastest globally.[2] Causes of death in children vary according to age. Globally, in 2011, the top five causes were preterm birth complications, diarrhoeal disease (DD), birth asphyxia, malaria and 'other' causes.[1] In SA, during the neonatal period, preterm birth, birth asphyxia and infections contributed to the majority of early deaths. Outside the neonatal period, HIV/AIDS and childhood infections (especially diarrhoea and pneumonia) are the major causes of death and are also responsible for the majority of childhood morbidity in SA.[3] According to the SA Child Healthcare Problem Identification Programme (PIP), for the period 2005 - 2009, DD was the second most important direct cause of death after acute respiratory infections.[4] In SA, the incidence of DD decreased in the under-5 age group from 286.4 cases per 1 000 population in 1998 to 95.9 cases per 1 000 population in 2011.[5] There was a decrease in DD incidence in all provinces. However, KwaZulu-Natal (KZN) has shown a much smaller decrease when compared with other provinces. KZN's DD incidence was above the national average with 139.1 cases per 1 000 population in 2011.[5] Child PIP statistics from Edendale Hospital (EDH), a regional hospital in KZN, between 2005 and 2013 showed that DD was the third most frequent cause of death in children under 5 years, but a decrease was noted in the overall under-5 in-hospital mortality rate (U5 IHMR). From January 2005 to July 2013, the U5 IHMR decreased from 8.4 to 2.5 deaths per 100 admissions.

In the 1978 declaration of Alma Ata, the availability of essential medicines was listed as one of the eight minimum requirements of primary healthcare.[6] The concept of essential medicines is that the availability of a limited and select range of medicines would lead to better healthcare, better drug management, better use of financial resources, and therefore improved healthcare. Twenty-five years after the declaration, over 100 countries had national drug policies, 156 countries had national or provincial essential medicines lists and over 130 countries had developed national treatment guidelines to provide objective and unbiased guidance on rational use of medicines.[7] National STGs were introduced in SA during 1996.[8] At EDH, an orientation programme is provided for all new doctors working in the paediatric department, irrespective of rank. This 2-week comprehensive training programme includes the assessment and management of DD and emphasises the overall importance of using guidelines in paediatrics. The objective of this study was to determine whether doctors in the EDH Paediatric Outpatient Department (POPD) followed the 2006 Standard Treatment Guidelines (STGs) and Essential Drugs List (EDL) for HospitalLevel Paediatrics when managing children with DD - the STGs and EDL for Hospital-Level Paediatrics 2006 were in use at the time of the study. A secondary objective was to assess differences in STG adherence between different ranks of attending doctor.

 

Methods

This was a descriptive cross-sectional study, using a retrospective review of patient records to perform a clinical audit. The setting was the POPD at EDH in Pietermaritzburg, KZN, during two summer (January, February) and two winter (June, July) months in 2013. Patients aged 2 months to 5 years attending the Edendale POPD with acute DD were included in the study. Patients were identified using the POPD register for the respective study months. Relevant patient records were then obtained from the hospital's records department. The following were excluded: children with chronic DD, children with another coincident serious illness and children with dysentery. It was postulated that a review of 150 - 200 patient records would provide sufficient data to describe doctors' adherence to the STGs. The first 100 patient records over the summer months and the first 100 patient records over the winter months were evaluated.

Two hundred patient records were retrieved, and 135 records met inclusion criteria. Sixty-five were excluded (Fig. 1). Ten key actions in the management of children with DD were evaluated by the principal investigator. Apart from the nutritional assessment (which included the evaluation of moderate and severe malnutrition as current best practice according to the National Department of Health), all the actions were based on the 2006 STGs and EDL for Hospital-Level Paediatrics, namely:

1. Correct nutritional assessment

2. Correct assessment for shock

3. Correct assessment for dehydration

4. Appropriate investigations

5. Appropriate fluid management plans according to the child's dehydration severity assessment

6. Appropriate prescriptions, specifically:

   a) prescription of zinc

   b) non-prescription of antibiotics

   c) non-prescription of anti-diarrhoeal mediation

7. Appropriate referral to the next place of care (home, oral rehydration corner or ward admission)

8. Adequate advice to caregivers regarding the diagnosis, severity of illness and ongoing care of their children.

For each of the ten actions, a compliance score was given, whereby compliant = 2, partially compliant =1 or non-compliant = 0.

A data collection tool was developed using a compliance scale (Appendix A). The tool also included demographic data (age, nutritional status, HIV status and rotavirus immunisation), the assessment of the child's fluid deficit (shock and dehydration) and the rank of attending doctor (intern, medical officer, registrar and paediatric specialist).

Data were analysed in Microsoft Excel (Microsoft Corp., USA). Simple descriptive statistics were used to assess adherence to STGs.

 

Results

Patient demographics

The median age ofpatients was 22 (range 2 - 60) months. The nutritional status was unknown in 53%. Retrospective analysis of nutritional status in the unknown group showed that 89% had no acute malnutrition, 9% were classified as having moderate acute malnutrition and 3% were classified as having severe acute malnutrition. Seventy-eight percent were HIV uninfected, and in 13% the HIV status was unknown. In 70% rotavirus vaccine had been given but in 22% this information was unknown. Over 40% of children were assessed as dehydrated and only 3% were assessed as shocked. Sixty-two percent of the patients were seen by interns and in 8% the doctor's rank was unknown (Table 1).

 

 

Adherence to STGs

Forty-seven percent of patients had a correct nutritional assessment. Forty-one percent of patients had a correct assessment for shock and 27% of patients had a correct assessment for dehydration. Twelve per cent had appropriate investigations undertaken. The most commonly omitted investigations were urine dipsticks and blood sugar finger prick. Ninety-seven percent of patients had fluid plans appropriate to their dehydration severity assessment. Thirty-nine percent of patients had zinc correctly prescribed. The correct non-prescription of antibiotics occurred in 84% of patients and no patients were prescribed anti-diarrhoeal medication, as outlined in the STGs. Ninety percent ofpatients received appropriate post-care referral. Patient records indicated that almost half of caregivers (47%) were adequately advised on the diagnosis, severity of the illness and ongoing care of their children (Table 2).

 

Discussion

DD is a major cause of childhood mortality in developing countries. The annual mortality report released by Statistics SA for deaths occurring in 2013 listed intestinal infectious diseases as the leading cause of death in children under 5 years of age.[9] At EDH, where DD is ranked as the third most frequent cause of death in children under 5 years, this study found significant non-adherence to STGs for the management of DD by doctors in a setting of high DD prevalence.

There was poor adherence in six of ten key actions for managing children with DD, which is cause for concern. For these six steps, the average compliance by rank of doctor was 38% for interns, 36% for medical officers and 24% for registrars. It appears that the more senior the doctor, the lower the adherence.

Nutrition

Of the 135 patients, only 47% had a correct nutritional assessment, with low adherence rates by all ranks of doctor (Table 2). All children accessing healthcare should have a correct nutritional assessment, both because of the high prevalence of malnutrition in the population served, and because a child's nutrition status informs correct fluid management in DD.

Shock and dehydration

Only 41% of children had a correct assessment for shock and only 27% were correctly assessed for dehydration. This could reflect poor quality of care, poor quality of guidelines or poor documentation, or a combination of all three. Proper assessment of shock and dehydration is an important part of providing proper emergency care for children.

Investigations

Adherence to requesting appropriate investigations was low (12%) for all ranks of doctor, mostly due to inadequate investigation.

Fluid management

Ninety-seven percent of patients appeared to have correct fluid management plans. However, this may have been an overestimate as doctors showed poor STG adherence for the assessment of shock and dehydration, making it difficult to match fluid plans with the actual clinical condition of the patient.

Prescribing Zinc

While it is accepted that the use of zinc is beneficial in DD,[10] only 39% of patients received zinc. In contrast to the overall trend by rank, registrars (53%) prescribed zinc more often than interns (36%).

Antibiotics

Sixteen percent of children had antibiotics prescribed, with no clear indication documented in the patient records, i.e. a condition other than DD. Antibiotic use is advocated in certain diarrhoeal conditions, e.g. dysentery, and also in some common medical conditions that may co-exist at the time of the diarrhoeal presentation. However, these patient records were specifically excluded from the study.

Anti-diarrhoeal medication

It was encouraging to find that no children were prescribed anti-diarrhoeal medication. This may be because the use of anti-diarrhoeal medication is generally strongly discouraged in the management of DD, by medical schools, in the clinical setting and in clinical guidelines.

Place of further care

Ninety percent of children were assigned to the correct place of further care. There was greater adherence among the medical officers (100%) and interns (93%), compared with the registrars (79%).

Caregiver advice/education

Forty-seven percent of caregivers were adequately counselled. A possible reason for this low adherence is that attending doctors may not have recorded their counselling of the caregivers in the patient record. Nevertheless it cannot be assumed that the caregivers were counselled about danger signs on discharge or the use of ORS in DD if this was not documented.

Rank of attending doctor

The results showed non-adherence to treatment guidelines irrespective of the rank of attending doctor. Registrar adherence to STGs was lower than interns for six of the ten actions, i.e. nutritional classification, shock assessment, dehydration assessment, use of investigations, further place of care and counselling of caregivers. Furthermore, registrars also scored lower than medical officers for five of the ten actions. This is a major concern as registrars are specialists-in-training and have an important role to play in supervising and teaching their junior colleagues, and in role modelling.

The study showed that guidelines were not being properly followed by doctors at EDH POPD. This may adversely affect the quality of care received by patients, the utilisation of resources, costs to the hospital and income for parents who may have to stay in hospital with their children.

It is not known from this study whether or not substantial non-adherence to DD guidelines directly impacts mortality. However, this possibility is also a cause for concern.

The study findings are surprising for a number of reasons. At medical schools, the pathophysiology and management of DD is taught in great detail through lectures and the use of prescribed texts. But focus on the management of DD according to the STGs in particular is often not included. Instead the focus is more on the use of Integrated Management of Childhood Illness (IMCI) guidelines for management of DD and other common conditions. In the IMCI guidelines, assessment of dehydration and fluid management is similar to that described in the STGs. In the authors' experience, the use of the STGs was first emphasised during internship and subsequent training years.

EDH is a typical KZN regional hospital providing primary and regional levels of care. It is possible that studies in other KZN hospitals may reveal similar findings of non-adherence to STGs.

Reasons given for non-adherence include lack of time due to high patient load, staff shortages, lack of supervision of junior doctors, increased pressure on senior doctors, poor documentation of findings in patient records and/or poor interpretation of clinical signs, all of which may have serious implications for the patient. Staff indifference to the use of guidelines is another possible factor. The actual reasons for non-adherence to the STGs need to be further elucidated.

Recommendations

The findings of this study suggest a few easily implementable actions:

1. Teaching on the importance of standard guideline usage (as opposed to teaching guideline content) during orientation training for staff, to ensure that all doctors irrespective of rank receive training in the use of STGs and understand the importance of STGs in disease management and prevention in children.

2. The introduction of a standardised clerking sheet to be used by doctors for patients presenting with DD, where all the information required for a successful consultation, as described in the STGs, is presented.

3. Regular record and clinical audit of patients presenting with DD to assess if guidelines are being adhered to and, if not, to assess the impact of this on morbidity and mortality.

4. Action plans based on audit results can lead to further strategies for improving quality of care for children with DD. The global target set for MDG 4 was to reduce U5 MR by two-thirds between 1990 and 2015. According to the MDG Report 2015, the global U5 MR has declined by more than half, with the rate of reduction of U5 MR more than tripling since the early 1990s.[10] In sub-Saharan Africa, the annual rate of reduction of U5 MR was over five times faster during 2005 - 2013 than during 1990 - 1995. Despite impressive improvements in most regions, current trends are not yet sufficient to meet the MDG 4 target. At today's rate of progress, it would take about 10 more years to reach the target.[11]

DD is a significant cause of childhood mortality in SA and more work needs to be done to limit unnecessary loss of life caused by this preventable illness. This study focused on one aspect of care by assessing if doctors adhered to STGs for the management of DD.

 

Conclusion

This study has identified that the majority of doctors at EDH POPD did not follow STGs in the management of children with acute DD. Solutions to the problem are broader than simply issuing instructions on guideline usage to junior doctors. As described in a recent article in The Lancet if a health system is weak, guidelines cannot compensate for it. Addressing issues in quality of care and supporting health systems is necessary to tackle the challenges of paediatric care in resource limited settings.[11]
