Épilepsie au Laos : le difficile parcours d’un antiépileptique de première ligne contribue à la forte carence de traitement

Management of epilepsy in Laos: Perceptions of healthcare professionals from Vientiane Capital province and traditional healers in Southern Laos

Background and aim

Traditional practices are deeply rooted in Lao people's perceptions and beliefs about health and illness.The objective of the study was to understand the perceptions of healthcare professionals and traditional healers regarding the management of epilepsy in Laos, and their reciprocal views.

Experimental procedure

An observational study was carried out in two areas of Laos from February to May 2017. Semi directive questionnaires were used to collect quantitative and qualitative data. Semiotic square was carried out to highlight relationships between attitudes of traditional healers and healthcare professionals. For quantitative approach, the proportions were reported, and the test used was Fisher's test for nominal variables. The mean and standard deviation expressed the continuous variables and the Student's t-test was used.

Results and conclusion

Epilepsy was cited by 90.9% of traditional healers as a convulsive disease with saliva or urine, and herbal medicines were predominantly used (86.4%) to treat it. Few healthcare professionals (26.5%) pointed out that they knew remedies to treat epilepsy other than antiepileptic drugs (AEDs), and 76.5% of healthcare professionals mentioned that epilepsy was a disease which only AEDs could treat. On the other hand, 54.5% of traditional healers confirmed a traditional remedy could cure completely epilepsy through long-term use. Ninety percent of traditional healers said the collaboration with healthcare professionals was a good idea and 44.1% of the healthcare professionals group said was complicated.The combination of these medicines for the management of epilepsy needs to be adapted to Lao's medical context.

Availability, affordability, and quality of essential antiepileptic drugs in Lao PDR

OBJECTIVE

Epilepsy is a chronic condition treatable by cost-effective antiepileptic drugs (AEDs), but limited access to treatment was documented. The availability and affordability of good quality of AEDs play a significant role in access to good health care. This study aimed to assess the availability, affordability, and quality of long-term AEDs in Lao PDR.

METHOD

A cross-sectional study was performed in both public and private drug supply chains in urban and rural areas in Lao PDR. Data on AEDs availability and price were obtained through drug suppliers. Affordability was estimated as the number of day wages the lowest-paid government employee must work to purchase a monthly treatment. Samples of AEDs were collected, and the quality of AEDs was assessed through Medicine Quality Assessment Reporting Guidelines.

RESULTS

Out of 237 outlets visited, only 50 outlets (21.1% [95% CI 16.1-26.8]) had at least one AED available. The availability was significantly different between urban (24.9%) and rural areas (10.0%), P = .017. Phenobarbital 100 mg was the most available (14.3%); followed by sodium valproate 200 mg (9.7%), phenytoin 100 mg (9.7%), and carbamazepine 200 mg (8.9%). In provincial/district hospitals and health centers, AEDs were provided free of charge. In other healthcare facilities, phenytoin 100 mg and phenobarbital 100 mg showed the best affordability (1.0 and 1.2 day wages, respectively) compared to carbamazepine 200 mg (2.3 days) and other AEDs. No sample was identified as counterfeit, but 15.0% [95% CI 7.1-26.6] of samples were classified as of poor quality.

SIGNIFICANCE

We quantified and qualified the various factors contributing to the high treatment gap in Lao PDR, adding to diagnostic issues (not assessed here). Availability remains very low and phenobarbital which is the most available and affordable AED was the worst in terms of quality. A drug policy addressing epilepsy treatment gap would reduce these barriers.

Access to Controlled Medicines in Low-Income Countries: Listening to Stakeholders in the Field

Little is known on current practices and challenges associated with the legal trade of medicines controlled under international conventions in low-income countries. This qualitative survey involved semi-structured interviews of stakeholders engaged in the trade of controlled medicines at a global level or at a country level in 3 African countries (Uganda, Kenya, Democratic Republic of the Congo). Nine interviews were conducted, including 3 international wholesalers, 2 relief organizations, 2 procurement officers, and 2 regulatory officers. Additionally, 4 other participants provided written information. All participants consistently reported that the current process of procuring controlled medicines in compliance with international conventions was long and complex given the number of administrative steps required for obtaining export and import authorizations, which are mandatory for both narcotic and psychotropic medicines. It may be difficult or impossible to obtain import authorizations from some health authorities in low-income countries because of long delays, mistakes in forms, absence or shortage of staff, or when annual national estimates are exceeded. The complexities of the trade of controlled medicines directly contribute to the lack of access to essential controlled medicines, both narcotics and psychotropics, in low-income countries.

Differences in knowledge about epilepsy and antiepileptic drugs among pharmacy-dispensing workers in Cambodia and in Lao PDR

Epilepsy is the most common neurological disorder encountered in primary care in Southeast Asia. People with epilepsy require long-term therapy management. Nonadherence to antiepileptic drugs (AEDs) has been identified as a major factor in suboptimal control of epilepsy. Pharmacies offer patients a first-line point of contact with the healthcare system. Many pharmacies operate with limited or nonqualified human resources that can lead to insufficient knowledge, inappropriate supply of medicines, and insufficient counseling.

OBJECTIVE

The aim of this study was to evaluate the qualification and knowledge concerning epilepsy and AEDs among pharmacy-dispensing workers who sell drugs to people with epilepsy.

METHOD

A cross-sectional qualitative study was conducted in public and private pharmacies, in both urban and rural areas of Cambodia and Lao People's Democratic Republic (Lao PDR). The knowledge was collected through a questionnaire.

RESULTS

A total of 180 respondents from 123 outlets in the two countries were included in this study. A proportion of 40.8% (31) of respondents in Cambodia and 38.5% (40) in Lao PDR were pharmacists, followed by sellers who did not received any healthcare training with a proportion of 18.4% (14) in Cambodia compared to 20.2% (21) in Lao PDR. Head trauma was cited as the main cause of epilepsy by 72.4% (55) in Cambodia and 27.2% (28) in Lao PDR (p < 0.001). Epilepsy was considered as a contagious disease by 6.6% (5) of respondents in Cambodia compared to 18.4% (19) in Lao PDR (p = 0.03). Eighty-seven percent (66) of respondents in Cambodia knew at least one long-term AED versus 67.3% (70) in Lao PDR (p = 0.003). Phenobarbital was mentioned in more than 90.0% of cases in both countries. In overall, 15.4% (21) thought that if seizures are controlled for some months, people with epilepsy could stop taking their AEDs. Only one respondent from Lao PDR was aware of drug-drug interaction between AEDs and oral contraception.

CONCLUSION

An educational intervention should be implemented to improve the knowledge of epilepsy and AEDs for pharmacy-dispensing workers. This could include advice for all pharmacy-dispensing workers in order to improve AED management and follow-up of therapeutic adherence.

Explanatory factors of adherence to community-based management of epilepsy in Lao PDR

RELEVANCE

A low level of knowledge about epilepsy among health workers, a context of stigmatizing sociocultural beliefs, and a low availability of antiepileptic drugs in Lao People's Democratic Republic (PDR) are major gaps in the medical management of people with epilepsy in this country.

OBJECTIVES

The principal objective of the study was to identify the associated factors of adherence to community healthcare structures in Lao PDR. Specific objectives were to evaluate patients' adherence status, practices and knowledge about epilepsy and its care, and factors influencing decision-making on therapeutic interventions.

MATERIALS AND METHODS

The study was an observational cross-sectional survey about knowledge, attitudes, and practices, handled from February to May 2016. Eighty-seven people with epilepsy were identified in two areas in the periphery of Vientiane Capital through an active screening in villages and homes. Semidirective questionnaires were conducted to collect quantitative and qualitative data. Quantitative analysis included a comparison of adherent vs. nonadherent people with epilepsy, using Chi-square or Fisher's test. Advanced qualitative lexical analysis was carried out on the open-ended questions.

RESULTS

Sixty-two people with epilepsy were included and the adherence rate to community care was 67.7%. The only sociodemographic variable that differed significantly between adherent and nonadherent members was the income level (p = 0.015): the wealthiest class of people with epilepsy did not adhere to community healthcare. Eleven percent of people with epilepsy thought that epilepsy was contagious, 80.6% that medication may reduce epilepsy seizure rates, and 33.9% that it was possible to cure epilepsy permanently. Physicians informed about the disease in 69.0% of adherent people with epilepsy and in 40.0% of nonadherent ones (p = 0.029), whereas villagers were involved in 29.0% and 50.0% of cases, respectively. There was a significant difference between the two groups for the prescribed antiepileptic drugs (p = 0.012): phenobarbital covered 73.8% of adherent people with epilepsy but only 40% of nonadherent ones. Half of nonadherent people with epilepsy went regularly to a central hospital in the Vientiane Capital, 15.0% went to Thailand, and 10.0% practiced self-medication in occasional mobilities.

CONCLUSION

A wider range of antiepileptic drugs at a reduced cost and the promotion of adherence to community healthcare would allow a better management of people with epilepsy in Lao PDR.

Is insufficient knowledge of epilepsy the reason for low levels of healthcare in the Lao PDR?

Background

The treatment gap for epilepsy is considerable in low and middle-income countries. In the Lao PDR it is estimated at over 90%. Health workers play a significant role in bridging the gap between people with epilepsy (PWE) and access to epilepsy care. In a national survey we assessed: 1) the knowledge and practices of health workers in the Lao PDR towards the disease, and, 2) patient attendance at health facilities.

Methods

We conducted a random three-stage sampling of health workers at the provincial, district and health center levels in 2009.

Results

Overall, 284 health workers were enrolled in 50 health facilities of 11 provinces: health centers 24.7%; district hospitals 23.2%; and province hospitals 52.1%. Only a minority of these (2.5%) recalled ever having received training or seeking information on epilepsy. Our survey showed a lack of knowledge in diagnosing and prescribing drugs for epilepsy, including phenobarbital, the first-line of treatment. The majority of respondents (59.9%) was unaware of the availability of antiepileptic drugs in health facilities. Only 10 (20%) health facilities, and no health centres, received people with epilepsy. It was estimated that one PWE per month receives medical attention. Traditional beliefs about PWE were common; such as the idea that epilepsy could be transmitted through saliva (63.2%). A higher attendance of PWE was observed in province hospitals where the knowledge of epilepsy care was higher. Global acceptance of people with epilepsy was low.

Conclusions

The low level of knowledge of epilepsy on the part of health workers may be contributing to the wide treatment gap in the Lao PDR. Improving knowledge of this disease and increasing the availability of antiepileptic drugs will reduce misconceptions about epilepsy, thus encouraging more PWE to seek treatment. Community-based educational programs and extensive advocacy for people with epilepsy only began in 2009.

Associated factors with adherence to antiepileptic drug in the capital city of Lao PDR

Available medical care for epilepsy and antiepileptic drugs (AED) are provided in Vientiane Municipality by district hospitals supported by a non-governmental organization, which is referred to as a community-based intervention (CB), and reference hospital which is referred to as hospital-based interventions (HB). Identifying underlying factors of AED adherence is of public health interest. A community-based cross-sectional survey among randomly selected patients with epilepsy (PWE) who were being cared in Vientiane Municipality was undertaken in 2010. The Morisky scale was used to assess the level of adherence. Univariate and multivariate logistic regression analyses were performed to address predictive factors. Overall, 99 PWE were included in the study. Overall adherence was estimated at 57.6%, 57.1% and 58.0% for the HB and CB group, respectively. High level of adherence was related to illiteracy, being on monotherapy and experiencing fewer seizures. Implementing closer medical care at primary level to PWE improves the likelihood of reducing primary and secondary treatment gap which is related to PWEs' adherence. An active intervention through a downstream channel of training of medical health staff from reference level to community level enhances the prescription of adequate AED, the improvement of the quality of relation between PWE and medical staff.
