Future of health care system tops agenda as CMA Board of Directors meets

The first part of the CMA''s efforts to spark a public debate on the future of Canada''s health care system is a “visioning exercise” in which the Board of Directors will attempt to spell out the association''s views on how the system should develop. The board also discussed CMA initiatives concerning two major public-health issues — smoking and blood transfusions.     

Drinking and Driving

Alcohol misuse generates many health and social problems at a cost that society is increasingly unwilling to sustain. One of the most tragic consequences of alcohol misuse is the result of drinking and driving. Each week, impaired drivers kill 40 Canadian men, women and children and injure 1250 others. The Canadian Medical Association (CMA), in its campaign against drinking and driving, has recommended that a condition of obtaining or renewing a driver''s licence include the individual''s written consent to allow the taking of blood samples by qualified medical personnel when deemed necessary by law enforcement agencies. CMA has recommended to the provinces that the legal age for the purchase and public possession of alcohol be raised to 21. CMA also supports the ban of all alcohol advertising in the electronic media and emphasizes that since alcohol is a drug, all containers should be visibly labelled “Misuse of this Product can be Injurious to Health”. CMA continues to support and encourage the federal and provincial governments in their battle to prevent alcohol-related deaths and injuries through education, control of advertising, use of breathalyzer devices, mandatory blood alcohol testing and legislation enacting stiffer penalties for drinking and driving.     

Resuscitation of the terminally ill

The CMA believes that there are conditions of ill health and inevitable death for which a “no resuscitation” order, signed by the attending physician, is appropriate and ethically acceptable. The association encourages physicians who are faced with the decision of writing a “no resuscitation” or “do not resuscitate” order to consider the clinical criteria and procedural guidelines in the Joint Statement on Terminal Illness. This protocol is intended as a basic, national guideline for those involved in the care of the terminally ill. Individual institutions may wish to develop their own directives as an adjunct to the national statement.     

The Clinical Impact of Chromosomal Microarray on Paediatric Care in Hong Kong

Objective

To evaluate the clinical impact of chromosomal microarray (CMA) on the management of paediatric patients in Hong Kong.

Methods

We performed NimbleGen 135k oligonucleotide array on 327 children with intellectual disability (ID)/developmental delay (DD), autism spectrum disorders (ASD), and/or multiple congenital anomalies (MCAs) in a university-affiliated paediatric unit from January 2011 to May 2013. The medical records of patients were reviewed in September 2013, focusing on the pathogenic/likely pathogenic CMA findings and their “clinical actionability” based on established criteria.

Results

Thirty-seven patients were reported to have pathogenic/likely pathogenic results, while 40 had findings of unknown significance. This gives a detection rate of 11% for clinically significant (pathogenic/likely pathogenic) findings. The significant findings have prompted clinical actions in 28 out of 37 patients (75.7%), while the findings with unknown significance have led to further management recommendation in only 1 patient (p<0.001). Nineteen out of the 28 management recommendations are “evidence-based” on either practice guidelines endorsed by a professional society (n = 9, Level 1) or peer-reviewed publications making medical management recommendation (n = 10, Level 2). CMA results impact medical management by precipitating referral to a specialist (n = 24); diagnostic testing (n = 25), surveillance of complications (n = 19), interventional procedure (n = 7), medication (n = 15) or lifestyle modification (n = 12).

Conclusion

The application of CMA in children with ID/DD, ASD, and/or MCAs in Hong Kong results in a diagnostic yield of ∼11% for pathogenic/likely pathogenic results. Importantly the yield for clinically actionable results is 8.6%. We advocate using diagnostic yield of clinically actionable results to evaluate CMA as it provides information of both clinical validity and clinical utility. Furthermore, it incorporates evidence-based medicine into the practice of genomic medicine. The same framework can be applied to other genomic testing strategies enabled by next-generation sequencing.     

Practitioner attitudes in the United States and United Kingdom toward decisions at the end of life: are medical ethicists out of touch?

Objective To assess whether UK and US health care professionals share the views of medical ethicists about medical futility, withdrawing or withholding treatment, ordinary or extraordinary interventions, and the doctrine of double effect. Design, subjects, and setting Answers to a 138-item attitudinal questionnaire completed by 469 UK nurses studying the Open University course on “Death and Dying” were compared with those of a similar questionnaire administered to 759 US nurses and 687 US physicians taking the Hastings Center course on “Decisions Near the End of Life.” Results Practitioners accept the relevance of concepts widely disparaged by bioethicists: double effect, medical futility, and the distinctions between heroic and ordinary interventions and withholding and withdrawing treatment. Within the UK nurses'' group, the responses of a “rationalist” axis of respondents who describe themselves as having “no religion” are closer to the bioethics consensus on withholding and withdrawing treatment. Conclusions Professionals'' beliefs differ substantially from the recommendations of their professional bodies and from majority opinion in bioethics. Bioethicists should be cautious about assuming that their opinions will be readily accepted by practitioners.     

Buffeted by harsh economic winds,medical schools turn a wary eye to the future

All parts of Canada''s health care system are facing fiscal pressures these days, but they are particularly great at Canada''s medical schools. However, Dr. David Hawkins of the Association of Canadian Medical Colleges is optimistic that all 16 of Canada''s medical schools will remain open, mainly because of the huge impact they have on health care in their local communities. “We don''t just turn out students — we raise the standard of health care in a whole community,” he says.     

Doctor,you're in tobacco sales!

The director of British Columbia''s Doctors'' Stop-Smoking Project says that, whether they recognize it or not, doctors have the best and most competitive position within the tobacco industry because they have the best product line. Dr. Frederic Bass says physicians'' products—health and freedom from addiction—will win against the competition, which can offer only smoke, addiction to nicotine and ill health. “We offer the better deal,” he says, “but are we selling like we could? That''s the issue.”     

Clinical Decision Support: Effectiveness in Improving Quality Processes and Clinical Outcomes and Factors That May Influence Success

The use of electronic health records has skyrocketed following the 2009 HITECH Act, which provides financial incentives to health care providers for the “meaningful use” of electronic medical record systems. An important component of the “Meaningful Use” legislation is the integration of Clinical Decision Support Systems (CDSS) into the computerized record, providing up-to-date medical knowledge and evidence-based guidance to the physician at the point of care. As reimbursement is increasingly tied to process and clinical outcomes, CDSS will be integral to future medical practice. Studies of CDSS indicate improvement in preventive services, appropriate care, and clinical and cost outcomes with strong evidence for CDSS effectiveness in process measures. Increasing provider adherence to CDSS recommendations is essential in improving CDSS effectiveness, and factors that influence adherence are currently under study.     

What can experience add to early medical education? Consensus survey

Objective To provide a rationale for integrating experience into early medical education (“early experience”).Design Small group discussions to obtain stakeholders'' views. Grounded theory analysis with respondent, internal, and external validation.Setting Problem based, undergraduate medical curriculum that is not vertically integrated.Participants A purposive sample of 64 students, staff, and curriculum leaders from three university medical schools in the United Kingdom.Results Without early experience, the curriculum was socially isolating and divorced from clinical practice. The abruptness of students'' transition to the clinical environment in year 3 generated positive and negative emotions. The rationale for early experience would be to ease the transition; orientate the curriculum towards the social context of practice; make students more confident to approach patients; motivate them; increase their awareness of themselves and others; strengthen, deepen, and contextualise their theoretical knowledge; teach intellectual skills; strengthen learning of behavioural and social sciences; and teach them about the role of health professionals.Conclusion A rationale for early experience would be to strengthen and deepen cognitively, broaden affectively, contextualise, and integrate medical education. This is partly a process of professional socialisation that should start earlier to avoid an abrupt transition. “Experience” can be defined as “authentic human contact in a social or clinical context that enhances learning of health, illness or disease, and the role of the health professional.”     

Public versus private care: philosophy,not economics,is shaping the debate

A debate is brewing on the future of private health care within Canada''s medicare system, and even though the federal government professes its intention to defend the existing public system, the growing rightward trend of Canadian voters may mean they are willing to consider more private care. Citizens may continue to express undying support for medicare as an “untouchable” public good, says Charlotte Gray, but they are less and less willing to pay for it through taxes.     

Victoria conference highlights differences in federal,provincial stands on health care issues

When Canada''s health ministers met in Victoria recently, the number of issues debated were yet another sign of the many problems facing Canada''s health care system. There were dis-agreements about the use of facility fees by private clinics, and concern about the huge impact federal cuts to transfer payments are going to have on provincial governments. British Columbia, for instance, faces 1996 federal cuts totalling $375 million — 5.8% of the province''s health care budget. As well, ministers debated the merits of a report discussing alternatives to the fee-for-service method of paying physicians. Dr. Jack Armstrong, the president, said the CMA does not favour one particular remuneration system over another, but feels strongly that doctors should have the right to choose the system they want.     

Patients Are Paying Too Much for Tuberculosis: A Direct Cost-Burden Evaluation in Burkina Faso

Background

Paying for health care may exclude poor people. Burkina Faso adopted the DOTS strategy implementing “free care” for Tuberculosis (TB) diagnosis and treatment. This should increase universal health coverage and help to overcome social and economic barriers to health access.

Methods

Straddling 2007 and 2008, in-depth interviews were conducted over a year among smear-positive pulmonary tuberculosis patients in six rural districts of Burkina Faso. Out-of-pocket expenses (direct costs) associated with TB were collected according to the different stages of their healthcare pathway.

Results

Median direct cost associated with TB was US$101 (n = 229) (i.e. 2.8 months of household income). Respectively 72% of patients incurred direct costs during the pre-diagnosis stage (i.e. self-medication, travel, traditional healers'' services), 95% during the diagnosis process (i.e. user fees, travel costs to various providers, extra sputum smears microscopy and chest radiology), 68% during the intensive treatment (i.e. medical and travel costs) and 50% during the continuation treatment (i.e. medical and travel costs). For the diagnosis stage, median direct costs already amounted to 35% of overall direct costs.

Conclusions

The patient care pathway analysis in rural Burkina Faso showed substantial direct costs and healthcare system delay within a “free care” policy for TB diagnosis and treatment. Whether in terms of redefining the free TB package or rationalizing the care pathway, serious efforts must be undertaken to make “free” health care more affordable for the patients. Locally relevant for TB, this case-study in Burkina Faso has a real potential to document how health programs'' weaknesses can be identified and solved.     

Health Hazard Appraisal Counseling—Continuing Evaluation

A program of annual health examinations was expanded to include counseling based on a computerized appraisal of individual patients'' specific health risk factors. Data obtained from a specially designed questionnaire, laboratory tests and a physical examination yielded a health hazard appraisal showing a number of weighted risk factors and their relation to ten leading causes of death as determined for that patient. From all of this information, a “risk age” was developed which could then be compared with the patient''s “true age.” The results were reviewed with each patient, and methods of correcting health hazards were stressed. The first annual retesting of a group of 107 examinees showed a net risk age reduction of 1.4 years (formerly reported in this journal). The longer term follow-up reported in this paper showed a net risk reduction of 2.38 years in a group of 26 examinees. The net risk age reduction in the two groups represented 32 and 40 percent, respectively, of the achievable risk age reduction when patients comply with suggestions made during risk reduction counseling. These findings indicate that health hazard appraisal counseling is an effective method of altering priorities of health practices.     

Traditional Health Beliefs and Practices Among Lower Class Black Americans

The medical belief system of lower class black Americans reflects their social, political and economic marginality in the larger society. A moderate life-style is regarded as the basis for good health with special emphasis on protecting one''s body from cold, keeping it clean inside and out and maintaining a proper diet. Illnesses and other life events are classified as “natural” or “unnatural.” Natural illnesses result from the effects of cold, dirt and improper diet on the body causing changes in the blood. A number of beliefs about blood and its functions have important clinical implications for the treatment of hypertension and venereal disease and for family planning. Natural illnesses also result from divine punishment and serve as an instrument of social control. Unnatural illnesses are the result of witchcraft and reflect conflict in the social network. It is believed that physicians do not understand and cannot effectively treat such illnesses, but a variety of traditional healers offer help to the victims. Physicians must elicit such beliefs if they are to interact effectively and sensitively with black patients. Social change is required, however, to eliminate the feelings of powerlessness at the root of many of the health problems of poor black Americans.     

Quality along the Continuum: A Health Facility Assessment of Intrapartum and Postnatal Care in Ghana

Objective

To evaluate quality of routine and emergency intrapartum and postnatal care using a health facility assessment, and to estimate “effective coverage” of skilled attendance in Brong Ahafo, Ghana.

Methods

We conducted an assessment of all 86 health facilities in seven districts in Brong Ahafo. Using performance of key signal functions and the availability of relevant drugs, equipment and trained health professionals, we created composite quality categories in four dimensions: routine delivery care, emergency obstetric care (EmOC), emergency newborn care (EmNC) and non-medical quality. Linking the health facility assessment to surveillance data we estimated “effective coverage” of skilled attendance as the proportion of births in facilities of high quality.

Findings

Delivery care was offered in 64/86 facilities; only 3-13% fulfilled our requirements for the highest quality category in any dimension. Quality was lowest in the emergency care dimensions, with 63% and 58% of facilities categorized as “low” or “substandard” for EmOC and EmNC, respectively. This implies performing less than four EmOC or three EmNC signal functions, and/or employing less than two skilled health professionals, and/or that no health professionals were present during our visit. Routine delivery care was “low” or “substandard” in 39% of facilities, meaning 25/64 facilities performed less than six routine signal functions and/or had less than two skilled health professionals and/or less than one midwife. While 68% of births were in health facilities, only 18% were in facilities with “high” or “highest” quality in all dimensions.

Conclusion

Our comprehensive facility assessment showed that quality of routine and emergency intrapartum and postnatal care was generally low in the study region. While coverage with facility delivery was 68%, we estimated “effective coverage” of skilled attendance at 18%, thus revealing a large “quality gap.” Effective coverage could be a meaningful indicator of progress towards reducing maternal and newborn mortality.     

Computer-Assisted Diagnosis of Abdominal Pain using “Estimates” Provided by Clinicians

This paper reports a comparison between two modes of computer-aided diagnosis in a real-time prospective trial involving 472 patients with acute abdominal pain. In the first mode the computer-aided system analysed each of the 472 patients by referring to data previously collated from a large series of 600 real-life patients. In the second mode the system used as a basis for its analysis “estimates” of probability provided by a group of six clinicians. The accuracy and reliability of both modes were compared with the performance of unaided clinicians.Using “real-life” data the computer system was significantly more effective than the unaided clinician. By contrast, when using the clinicians'' own estimates the computer-aided system was often less effective than the unaided clinician—especially when diagnosing less common disorders. It seems, firstly, that future systems for computer-aided diagnosis should employ data from real-life and not clinicians'' estimates, and, secondly, that clinicians themselves cannot analyse cases in a probabilistic fashion, since often they have little idea of what the “true” probabilities are.     

Challenges for Routine Health System Data Management in a Large Public Programme to Prevent Mother-to-Child HIV Transmission in South Africa

Background

Recent changes to South Africa''s prevention of mother-to-child transmission of HIV (PMTCT) guidelines have raised hope that the national goal of reducing perinatal HIV transmission rates to less than 5% can be attained. While programmatic efforts to reach this target are underway, obtaining complete and accurate data from clinical sites to track progress presents a major challenge. We assessed the completeness and accuracy of routine PMTCT data submitted to the district health information system (DHIS) in three districts of Kwazulu-Natal province, South Africa.

Methodology/Principal Findings

We surveyed the completeness and accuracy of data reported for six key PMTCT data elements between January and December 2007 from all 316 clinics and hospitals in three districts. Through visits to randomly selected sites, we reconstructed reports for the same six PMTCT data elements from clinic registers and assessed accuracy of the monthly reports previously submitted to the DHIS. Data elements were reported only 50.3% of the time and were “accurate” (i.e. within 10% of reconstructed values) 12.8% of the time. The data element “Antenatal Clients Tested for HIV” was the most accurate data element (i.e. consistent with the reconstructed value) 19.8% of the time, while “HIV PCR testing of baby born to HIV positive mother” was the least accurate with only 5.3% of clinics meeting the definition of accuracy.

Conclusions/Significance

Data collected and reported in the public health system across three large, high HIV-prevalence Districts was neither complete nor accurate enough to track process performance or outcomes for PMTCT care. Systematic data evaluation can determine the magnitude of the data reporting failure and guide site-specific improvements in data management. Solutions are currently being developed and tested to improve data quality.     

Issues in Health Care of Middle Eastern Patients

Relationships between Middle Eastern patients and Western health care professionals are often troubled by mutual misunderstanding of culturally influenced values and communication styles. Although Middle Easterners vary ethnically, they do share a core of common values and behavior that include the importance of affiliation and family, time and space orientations, interactional style and attitudes toward health and illness. Problems in providing health care involve obtaining adequate information, “demanding behavior” by a patient''s family, conflicting beliefs about planning ahead and differing patterns of communicating grave diagnoses or “bad news.” There are guidelines that will provide an understanding of the cultural characteristics of Middle Easterners and, therefore, will improve rather than impede their health care. A personal approach and continuity of care by the same health care professional help to bridge the gap between Middle Eastern cultures and Western medical culture. In addition, periodic use of cultural interpreters helps ameliorate the intensity of some cultural issues.
