Are treatment guides and rational drug use policies adequately exploited in combating respiratory system diseases?

National standard treatment guidelines: their impact on medicine use indicators in a resource-limited setting

Objectives

Standard treatment guidelines improve patient care outcomes. Few studies assess the impact of standard treatment guidelines on population-level medicine use indicators in resource limited settings in sub-Saharan Africa, where the burden of disease is greatest. The objective of this study was to determine the immediate and long-term impact of the national standard treatment guidelines on medicine use indicators at the population-level in Namibia.

Methods

An interrupted time-series modeling of the impact of national standard treatment guidelines implemented in Namibia in 2011, on population-level medicine use indicators. Antibiotic, generic and polypharmacy prescribing indicators were abstracted from the national Pharmaceutical Information System, over an eight-year period, 2007– 2015. This generated 15-quarterly time points. The impact was estimated by changes in trends of the indicators, immediately and after the intervention using R-software. The immediate impact was reflected by level change while long term impact was determined by trends/quarterly change after standard treatment guideline implementation.

Key findings

Data points from 522 Pharmaceutical Information System reports from 38 health facilities were included. The eight-year period estimates were, 2.9 ± 0.1 medicines prescribed per outpatient, 48.1 ± 2.5% of prescriptions had an antibiotic and 74.0 ± 4.2% of medicines were prescribed by generic name. Of the 13 regions, 61.3% and 53.8% had a decline in the average medicines per prescription and prescriptions with antibiotics respectively, as well as 53.8% of the regions had an increase in prescribing of generic medicines immediately after implementation of the standard treatment guidelines. Thereafter, quarterly trends in the three indicators did not significantly improve after the intervention at national and in all regions, except for generic prescribing in Oshikoto region, 4.5% (95% CI: 2.6 – 6.3%, P < 0.001).

Conclusion

Whilst national standard treatment guidelines immediately improved medicine use indicators, it is discouraging that the improvement over time was marginal across regions and was not sustained at the national level. Robust point of care interventions is needed for sustained and effective implementation of standard treatment guidelines.

How do hospital respiratory clinicians perceive antimicrobial stewardship (AMS)? A qualitative study highlighting barriers to AMS in respiratory medicine

BACKGROUND

Suboptimal antibiotic use in respiratory infections is widespread in hospital medicine and primary care. Antimicrobial stewardship (AMS) teams within hospitals, commonly led by infectious diseases physicians, are frequently charged with optimizing the use of respiratory antibiotics, but there is limited information on what drives antibiotic use in this area of clinical medicine, or on how AMS is perceived.

AIM

To explore the perceptions of hospital respiratory clinicians on AMS in respiratory medicine.

METHODS

In-depth interviews were conducted with 28 clinicians (13 doctors and 15 nurses) from two hospitals in Australia. Data were analysed thematically using the framework approach.

FINDINGS

Four key barriers to the integration of AMS processes within respiratory medicine, from the participants' perspectives, were identified: CONCLUSIONS: AMS processes are introduced in hospitals with established social structures and knowledge bases. This study found that AMS in respiratory medicine challenges and conflicts with many of these dynamics. If the influence of these dynamics is not considered, AMS processes may not be effective in containing antibiotic use in hospital respiratory medicine.

Are We Economically Efficient Enough to Increase the Potential of in Vitro Proliferation of Osteoblasts by Means of Pharmacochemical Agents?

Background:

The aim of this study was to test the necessity of using expensive and unaccesible pharmacological-chemical agents in the proliferation of bone tissue cultures and in the induction of mineralized matrix formation to increase the osteogenic effect.

Methods:

For this purpose, human primary cell cultures were prepared and then divided into two groups. Whereas the cells in group I were fed with an osteoblast stimulator medium containing Dulbecco’s Modified Eagle Medium (DMEM) and β-glycerophosphate, the cells in group II were fed with DMEM containing dexamethasone and 2-phospho-L-ascorbic acid trisodium salt. Both groups were evaluated in terms of viability, toxicity, and proliferation and then compared in terms of cell surface morphology through inverted light and environmental scanning electron microscopy. In addition to immunoflow cytometric analyses, the effects of alkaline phosphatase activities were evaluated using the spectrophotometric method to examine the osteoblastic activities. Costs were calculated in the currency of the European Union (Euros). The Tukey Honestly Significant Difference test was used to reach the statistical evaluation of the data after the analysis of variance.

Results:

It was reported that the level of the alkaline phosphates was higher in group I compared to group II. It was observed that the surface morphology quality, the number of living cells, and proliferation were higher in group II and that the results were deemed statistically significant.

Conclusion:

It was found that the 2-phospho-L-ascorbic acid trisodium salt and dexamethasone mixture was as effective as the expensive commercial kits on the osteogenic effect on human primary bone tissue.
