A starting point in the evaluation of the outcome of care: an example using cancer registry information

Many health services worldwide are paying increasing attention to the evaluation of care. However, most studies in the past have concentrated on structure and process instead of outcome. The objective of this paper is to show how a fairly simple technique can provide a possible feedback loop to a health service system. A study on patients with lung cancer in East Anglia, UK is used as an example. Using information which was more or less routinely collected in cancer registration, the study showed that there was no significant difference between the survival of patients seen in the eight districts in East Anglia. Adjustment by the use proportional hazard modelling for prognostic factors including age, sex, histological type, stage and whether active treatment was given did not alter the outcome. This finding was slightly unexpected in view of the presumed (yet not documented) variation in enthusiasm and expertise among the districts. Such a result should be seen as a starting point for studies designed to examine the effects of the level of care provided and resource use on the length and quality of survival. While the methodology requires refinement and substantial local difficulties may arise, development of similar researches on the outcome of care should be encouraged in Hong Kong.published_or_final_versio

Differential Proteomic Analysis of Human Saliva using Tandem Mass Tags Quantification for Gastric Cancer Detection.

Novel biomarkers and non-invasive diagnostic methods are urgently needed for the screening of gastric cancer to reduce its high mortality. We employed quantitative proteomics approach to develop discriminatory biomarker signatures from human saliva for the detection of gastric cancer. Salivary proteins were analyzed and compared between gastric cancer patients and matched control subjects by using tandem mass tags (TMT) technology. More than 500 proteins were identified with quantification, and 48 of them showed significant difference expression (p < 0.05) between normal controls and gastric cancer patients, including 7 up-regulated proteins and 41 down-regulated proteins. Five proteins were selected for initial verification by ELISA and three were successfully verified, namely cystatin B (CSTB), triosephosphate isomerase (TPI1), and deleted in malignant brain tumors 1 protein (DMBT1). All three proteins could differentiate gastric cancer patients from normal control subjects, dramatically (p < 0.05). The combination of these three biomarkers could reach 85% sensitivity and 80% specificity for the detection of gastric cancer with accuracy of 0.93. This study provides the proof of concept of salivary biomarkers for the non-invasive detection of gastric cancer. It is highly encouraging to turn these biomarkers into an applicable clinical test after large scale validation

Can short-term residential care for stroke rehabilitation help to reduce the institutionalization of stroke survivors?

Background: Stroke survivors may not be receiving optimal rehabilitation as a result of a shortage of hospital resources, and many of them are institutionalized. A rehabilitation program provided in a short-term residential care setting may help to fill the service gap. Objectives: The primary objectives of this study were, first, to examine whether there were significant differences in terms of rehabilitation outcomes at 1 year after admission to the rehabilitation program (defined as baseline) between those using short-term residential care (intervention group) and those using usual geriatric day hospital care (control group), and, second, to investigate whether lower 1-year institutionalization rates were observed in the intervention group than in the control group. Participants: 155 stroke survivors who completed at least the first follow-up at 4 months after baseline. Intervention: The intervention group was stroke survivors using self-financed short-term residential care for stroke rehabilitation. The control group was stroke survivors using the usual care at a public geriatric day hospital. Measurements: Assessments were conducted by trained research assistants using structured questionnaires at baseline, 4 months, and 1 year after baseline. The primary outcome measures included Modified Barthel Index score, Mini-Mental Status Examination score, and the institutionalization rate. Results: Cognitive status (as measured by Mini-Mental Status Examination score) of patients in both groups could be maintained from 4 months to 1 year, whereas functional status (as measured by Modified Barthel Index score) of the patients could be further improved after 4 months up to 1 year. Meanwhile, insignificant between-group difference in rehabilitation outcomes was observed. The intervention participants had a significantly lower 1-year institutionalization rate (15.8%) than the control group (25.8%). Conclusion: Short-term residential care for stroke rehabilitation promoted improvements in rehabilitation outcomes comparable with, if not better than, the usual care at geriatric day hospital. Furthermore, it had a significantly lower 1-year institutionalization rate. This type of service could be promoted to prevent institutionalization.published_or_final_versio

Counterfeit drugs and the online pharmaceutical trade, a threat to public safety

Counterfeit pharmaceuticals are a serious and ever-growing threat to public safety. Monitoring the trade is difficult, resulting in the precise scale of the problem being unknown, however evidence shows that it is not just lifestyle drugs that are targeted nowadays. Adverse health problems, including fatalities, have resulted from consumers self-medicating with counterfeit products. Without efforts to enhance the public's knowledge, the problem will continue to persist. The internet is facilitating the trade by providing counterfeiters with a large consumer base and limited risks. The dark net within it allows for anonymous transactions between manufacturer, distributer and consumer. While some online pharmacies are legitimate, there are a growing number of those that are unverified which sell dangerous counterfeit products. Both the packaging and medication are becoming increasingly sophisticated, making it difficult for consumers and law enforcement to identify them without chemical analysis. Counterfeit batches have also been detected in established legal trade routes whereby they are able to, if undetected, end up in high street pharmacies and hospitals. Multiple organisations have set up worldwide operations to dismantle the trade however this is a complex and evolving problem that without significant changes to legislation may never be fully
