Should we beware of the Precautionary Principle?

ECONOMIC POLICY, Issue 33 2001
Christian Gollier
How should society deal with risks when there is scientific uncertainty about the size of these risks? There has been much recent discussion of the Precautionary Principle, which states that lack of full scientific knowledge should not be used as a reason to postpone cost,effective preventive measures. We show in this paper that the Precautionary Principle contradicts one important intuition about the right way to act in the face of risk, namely the principle of ,looking before you leap'. When we expect to learn more about the future, the effectiveness of our preventive measures will be greater if we learn before we act. However, a number of other ways of taking uncertainty into account are consistent with a reasonable interpretation of the Precautionary Principle. First, postponing preventive measures may increase our vulnerability to damage, which induces a precautionary motive for risk,prevention, similar to the precautionary savings motive. Secondly, stronger preventive actions often yield more flexibility for the future, so that acting early has an option value. Thirdly, when better information comes from a process of learning,by,doing, the risk associated with early events is amplified by the information they yield about the future. This plays a role analogous to that of an increase in risk aversion, making us more cautious. Fourthly, because imperfect knowledge of the risk makes it difficult to insure, the social cost of risk should include a risk premium. Finally, uncertainty about the economic environment enjoyed by future generations should be taken into account. This raises the benefit of acting early to prevent long,term risks. If the Precautionary Principle sometimes gives good and sometimes gives bad advice, there is no escape from the need to undertake a careful cost,benefit analysis. We show that standard cost,benefit analysis can be refined to take account of scientific uncertainty, in ways that balance the Precautionary Principle against the benefits of waiting to learn before we act. Furthermore, it is important that they be used to do so, for instinct is an unreliable guide in such circumstances. Abandoning cost,benefit analysis in favour of simple maxims can result in some seriously misleading conclusions. [source]


Pressure ulcers: validation of two risk assessment scales

JOURNAL OF CLINICAL NURSING, Issue 3 2005
Tom Defloor PhD
Aims and objectives., To compare the predictive value of two pressure ulcer risk assessment scales (Braden and Norton) and of clinical judgement. To evaluate the impact of effective preventive measures on the predictive validity of the two risk assessment scales. Methods., Of the 1772 participating older patients, 314 were randomly selected and assigned to the ,turning' group; 1458 patients were assigned to the ,non-turning' group. Using the Braden and the Norton scale the pressure ulcer risk was scored twice weekly during a four-week period. Clinical assessment was monitored daily. The patients at risk in the ,turning' group (Braden score <17 or Norton score <12) were randomly assigned to a two-hour turning schedule or to a four-hour turning schedule in combination with a pressure-reducing mattress. The ,non-turning' group received preventive care based on the clinical judgement of the nurses. Results., The diagnostic accuracy was similar for both scales. If nurses act according to risk assessment scales, 80% of the patients would unnecessarily receive preventive measures. The use of effective preventive measures decreased the predictive value of the risk assessment scales. Nurses predicted pressure ulcer development less well than the Braden and the Norton scale. Only activity, sensory perception, skin condition and existence of old pressure ulcers were significant predictors of pressure ulcer lesions. Relevance to clinical practice., The effectiveness of the Norton and Braden scales is very low. Much needless work is done and expensive material is wrongly allocated. The use of effective preventive measures decreases the predictive value of the risk assessment scales. Although the performance of the risk assessment scales is poor, using a risk assessment tool seems to be a better alternative than relying on the clinical judgement of the nurses. [source]


HYPERTENSION MANAGEMENT: LIFESTYLE INTERVENTIONS IN A TRANSCULTURAL CONTEXT

JOURNAL OF RENAL CARE, Issue 4 2009
Tai Mooi Ho
SUMMARY Hypertension is a risk factor for cardiovascular and kidney diseases. According to estimation, the prevalence of hypertension will increase unless extensive and effective preventive measures are implemented. The diversity of languages and cultures of the hypertensive patients requiring adequate blood pressure control make communications difficult in many instances. Nursing intervention for patients to adopt a healthy lifestyle requires effective communication. But the communication problems encountered in a culturally diverse context can result in undesirable outcomes for the patients and the health-care team. This paper describes the production of a document to assist staff address the difficulty in intercultural communication, which could be used anywhere in the world. This document can facilitate nursing intervention to achieve optimal hypertension management in a transcultural context, responding to the challenge regarding preventive measures to halt increase in hypertension prevalence.

Universal problems during residency: abuse and harassment

MEDICAL EDUCATION, Issue 7 2009
Shizuko Nagata-Kobayashi
Objectives, Perceived abuse or harassment during residency has a negative impact on residents' health and well-being. This issue pertains not only to Western countries, but also to those in Asia. In order to launch strong international preventive measures against this problem, it is necessary to establish the generality and cultural specificity of this problem in different countries. Therefore, we investigated mistreatment among resident doctors in Japan. Methods, In 2007, a multi-institutional, cross-sectional survey was conducted at 37 hospitals. A total of 619 residents (409 men, 210 women) were recruited. Prevalence of mistreatment in six categories was evaluated: verbal abuse; physical abuse; academic abuse; sexual harassment; gender discrimination, and alcohol-associated harassment. In addition, alleged abusers, the emotional effects of abusive experiences, and reluctance to report the abuse to superiors were investigated. Male and female responses were statistically compared using chi-square analysis. Results, A total of 355 respondents (228 men, 127 women) returned a completed questionnaire (response rate 57.4%). Mistreatment was reported by 84.8% of respondents (n = 301). Verbal abuse was the most frequently experienced form of mistreatment (n = 256, 72.1%), followed by alcohol-associated harassment (n = 184, 51.8%). Among women, sexual harassment was also often reported (n = 74, 58.3%). Doctors were most often reported as abusers (n = 124, 34.9%), followed by patients (n = 77, 21.7%) and nurses (n = 61, 17.2%). Abuse was reported to have occurred most frequently during surgical rotations (n = 98, 27.6%), followed by rotations in departments of internal medicine (n = 76, 21.4%), emergency medicine (n = 41, 11.5%) and anaesthesia (n = 40, 11.3%). Very few respondents reported their experiences of abuse to superiors (n = 36, 12.0%). The most frequent emotional response to experiences of abuse was anger (n = 84, 41.4%). Conclusions, Mistreatment during residency is a universal phenomenon. Deliberation on the occurrence of this universally wrong tradition in medical culture will lead to the establishment of strong preventive methods against it. Current results indicate that alcohol-associated harassment during residency is a Japanese culture-specific problem and effective preventive measures against this are also urgently required.

Prospective evaluation of acute and chronic renal function in children following matched related donor hematopoietic stem cell transplantation. Pediatr Transplantation 2010: 14: 138,144. © 2009 John Wiley & Sons A/S. Abstract:, Acute and chronic renal impairment are important complications after HSCT. A prospective study was conducted to investigate the glomerular renal function in children who received allogeneic HSCT from matched related donors. Non-radiation conditioning regimens were used in all but one patient. CrCl and serial measurements of serum creatinine were evaluated prior to HSCT, within the first 100 days and one yr after. AKI was defined as at least a 1.5-fold rise in pre-HSCT serum creatinine within the first 100 days and classified as grade 1 to 3 according to the new definition criteria proposed by "AKI Network." Fifty-seven patients were enrolled in the study and 24 patients (42%) had AKI. CsA, amphotericin B, and SOS were found as risk factors for AKI. One yr after HSCT five patients (10%) had CKD and none of them required dialysis. None of the parameters were found as a predictor for CKD. We conclude that AKI is an important complication of HSCT. Careful monitoring of renal function, minimizing the use of nephrotoxic medication, prophylaxis, and effective treatment of SOS might be effective preventive measures to decrease the incidence of AKI.
