RESUMEN

OBJECTIVE: To assess the quality of antibiotics sampled from authorised sales outlets (ATs) (i.e. hospitals/health centres, pharmacies and licensed chemical shops) and unauthorised sales outlets (UATs) (mainly street vendors) in Ghana and to explore the health-seeking behaviour of medicine consumers. METHODS: The contents of 14 active pharmaceutical ingredients (APIs) in 348 sampled products were determined using a validated liquid chromatography-tandem mass spectrometry (LC-MS/MS) method. Data on health-seeking practices were collected through entry and exit interviews and field observations from ATs and UATs. RESULTS: It was observed that 66.38% of all sampled antibiotic products were substandard; they either contained less (<90%) or more API (>110%) than the label claim. Medicines from UATs recorded substantially less API contents than those from ATs (F(2,419)  = 43.01, P < 0.0001). For example, 90.54% of street vendor samples contained < 90% of the APIs. 75.93% of consumers often sought self-treatment with drugs without a prescription from UATs, as they perceived UATs as easily accessible, trustworthy and knowledgeable, and their medicines as inexpensive. These consumers rather thought of the formal healthcare providers as alternative sources. CONCLUSIONS: Consumers who purchase from UATs are at high risk of receiving substandard medicines. The quality of medicines in the national healthcare system, in the supply chain and in the distribution system needs to be monitored regularly to reduce the incidence of substandard medicines and their impact on antimicrobial resistance. The fight against substandard medicines needs to incorporate a full understanding of socioeconomic factors that drive consumer decisions regarding their health and choice of healthcare providers.


OBJECTIF: Evaluer la qualité des antibiotiques prélevés auprès des vendeurs autorisés (VA) (c'est-à-dire les hôpitaux/centres de santé, les pharmacies et les magasins de produits chimiques agréés) et des vendeurs non autorisés (VNA) (principalement les vendeurs de rue) au Ghana et étudier le comportement des utilisateurs de médicaments en quête de santé. MÉTHODES: Le contenu de 14 principes actifs (PA) pharmaceutiques dans 348 produits échantillonnés a été déterminé à l'aide d'une méthode validée de chromatographie liquide et de spectrométrie de masse en tandem (LC-MS/MS). Les données sur les pratiques de recherche de santé ont été collectées par le biais d'entretiens d'entrée et de sortie, et d'observations sur le terrain des VA et des VNA. RÉSULTATS: Il a été observé que 66,38% de tous les produits antibiotiques échantillonnés étaient inférieurs aux normes; ils contenaient soit moins (<90%), soit plus de PA (>110%) que ce qui était indiqué sur la notice. Les médicaments provenant des VNA ont enregistré une quantité de PA sensiblement inférieure à celle des VA (F(2,419)  = 43.01, P < 0,0001). Par exemple, 90,54% des échantillons de vendeurs de rue contenaient <90% de PA. 75,93% des utilisateurs ont souvent cherché à se soigner eux-mêmes avec des médicaments sans ordonnance des VNA, car ils ont perçu les VNA comme étant facilement accessibles, fiables et bien informés, et leurs médicaments comme étant peu coûteux. Ces utilisateurs considéraient également les prestataires de soins de santé officiels comme des sources alternatives. CONCLUSIONS: Les utilisateurs qui s'approvisionnent auprès des VNA courent un risque élevé de recevoir des médicaments de qualité inférieure. La qualité des médicaments dans le système national de santé, dans la chaîne d'approvisionnement et dans le système de distribution doit être contrôlée régulièrement pour réduire l'incidence des médicaments de qualité inférieure et leur impact sur la résistance aux antimicrobiens. La lutte contre les médicaments de qualité inférieure doit intégrer une compréhension complète des facteurs socioéconomiques qui déterminent les décisions des utilisateurs concernant leur santé et le choix des prestataires de soins de santé.

RESUMEN

Purpose Within human services, client satisfaction is highly prioritised and considered a mark of responsiveness in service delivery. A large body of research has examined the concept of satisfaction from the perspective of service users. However, not much is known about how service providers construct client satisfaction. The purpose of this paper is to throw light on healthcare professionals' perspectives on patient satisfaction, using tuberculosis (TB) clinics as a case study. Design/methodology/approach In-depth interviews were conducted with 35 TB clinic supervisors purposively sampled from six out of the ten regions of Ghana. An unstructured interview guide was employed. The recorded IDIs were transcribed, edited and entered into QSR NVivo 10.0 and analysed inductively. Findings Respondents defined service satisfaction as involving education/counselling (on drugs, nature of condition, sputum production, caregivers and contacts of patients), patient follow-up, assignment of reliable treatment supporters as well as being attentive and receptive to patients, service availability (e.g. punctuality at work, availability of commodities), positive assurances about disease prognosis and respect for patients. Practical implications Complementing opinions of health service users with those of providers can offer key performance improvement areas for health managers. Originality/value To the best of the authors' knowledge, this is a first study that has examined healthcare providers' views on what makes their clients satisfied with the services they provide.

RESUMEN

INTRODUCTION: Antibiotic resistance, associated with inappropriate drug use, is a global public health threat. The pharmaceutical sectors in developing countries are poorly regulated leading to antibiotic sales and use without a prescription. The study documents the treatment of acute illnesses in households and the antibiotic dispensing practices of medicine sales outlets in Eastern region, Ghana. METHOD: Twice-weekly illness recall visits were made to 12 households in three rural communities over eight consecutive weeks. Detailed fieldnotes were taken and analysed using a thematic approach. Quantitative counts of health events and treatment were also conducted. Dispensing practices were systematically observed and documented in three rural and three urban medicine outlets for analysis. RESULT: Fever, abdominal, and respiratory symptoms were the most common causes of ill-health in the 12 households. Most (65%) medicine-use events involved self-treatment with pharmaceuticals; 40% of medicine-use events involved antibiotics, often without a prescription. Although the number of antibiotic transactions without prescription in rural medicine outlets (n = 139, 27.4%) was statistically significantly more than in urban pharmacies (n = 140, 13.5%); z = 6.7, p < .0001), the volume of antibiotics sold in pharmacies was higher. Penicillins were the most commonly dispensed antibiotics constituting 30% of antibiotic sales in urban medicine outlets and 46% in rural ones. The lack of controls in the dispensing of antibiotics, community knowledge and use of antibiotics in ways inconsistent with biomedical recommendations, poverty and perceived barriers to formal healthcare were factors that influenced the inappropriate use of antibiotics. CONCLUSION: Self-medication, including antibiotic self-prescription, constitutes an integral part of healthcare in the study settings and the qualitative data provides a contextual understanding of over-the-counter antibiotic acquisition and use. Inappropriate antibiotic use is apparent in the study settings. Stricter regulation of the pharmaceutical sector, training of dispensers and evidence-based treatment guidelines, and public education are potential interventions.

RESUMEN

Resistance to antibiotics is increasing globally and is a threat to public health. Research has demonstrated a correlation between antibiotic use and resistance development. Developing countries are the most affected by resistance because of high infectious disease burden, limited access to quality assured antibiotics and more optimal drugs and poor antibiotic use practices. The appropriate use of antibiotics to slow the pace of resistance development is crucial. The study retrospectively assessed antibiotic prescription practices in four public and private primary health-care facilities in Eastern Region, Ghana using the WHO/International Network for the Rational Use of Drugs rational drug use indicators. Using a systematic sampling procedure, 400 prescriptions were selected per facility for the period April 2010 to March 2011. Rational drug use indicators were assessed in the descriptive analysis and logistic regression was used to explore for predictors of antibiotic prescription. Average number of medicines prescribed per encounter was 4.01, and 59.9% of prescriptions had antibiotics whilst 24.2% had injections. In total, 79.2% and 88.1% of prescribed medicines were generics and from the national essential medicine list, respectively. In the multivariate analysis, health facility type (odds ratio [OR] = 2.05; 95% confidence interval [CI]: 1.42, 2.95), patient age (OR = 0.97; 95% CI: 0.97, 0.98), number of medicines on a prescription (OR = 1.85; 95% CI: 1.63, 2.10) and 'no malaria drug' on prescription (OR = 5.05; 95% CI: 2.08, 12.25) were associated with an antibiotic prescription. A diagnosis of upper respiratory tract infection was positively associated with antibiotic use. The level of antibiotic use varied depending on the health facility type and was generally high compared with the national average estimated in 2008. Interventions that reduce diagnostic uncertainty in illness management should be considered. The National Health Insurance Scheme, as the main purchaser of health services in Ghana, offers an opportunity that should be exploited to introduce policies in support of rational drug use.

RESUMEN

Development of antimicrobial resistance has been assigned to excess and misuse of antimicrobial agents. Staphylococci are part of the normal flora but are also potential pathogens that have become essentially resistant to many known antibiotics. Resistances in coagulase negative staphylococci (CoNS) are suggested to evolve due to positive selective pressure following antibiotic treatment. This study investigated the presence of the nine most commonly used antimicrobial agents in human urine from outpatients in two hospitals in Ghana in relation to CoNS resistance. Urine and CoNS were sampled (n = 246 and n = 96 respectively) from patients in two hospitals in Ghana. CoNS were identified using Gram staining, coagulase test, and MALDI-TOF/MS, and the antimicrobial susceptibility to 12 commonly used antimicrobials was determined by disk diffusion. Moreover an analytical method was developed for the determination of the nine most commonly used antimicrobial agents in Ghana by using solid-phase extraction in combination with HPLC-MS/MS using electron spray ionization. The highest frequency of resistance to CoNS was observed for penicillin V (98%), trimethoprim (67%), and tetracycline (63%). S. haemolyticus was the most common isolate (75%), followed by S. epidermidis (13%) and S. hominis (6%). S. haemolyticus was also the species displaying the highest resistance prevalence (82%). 69% of the isolated CoNS were multiple drug resistant (≧ 4 antibiotics) and 45% of the CoNS were methicillin resistant. Antimicrobial agents were detected in 64% of the analysed urine samples (n = 121) where the most frequently detected antimicrobials were ciprofloxacin (30%), trimethoprim (27%), and metronidazole (17%). The major findings of this study was that the prevalence of detected antimicrobials in urine was more frequent than the use reported by the patients and the prevalence of resistant S. haemolyticus was more frequent than other resistant CoNS species when antimicrobial agents were detected in the urine.
