Background: Occupational therapy interventions in the community, a fast expanding practice setting, are central to an important social priority, the ability to live at home. These interventions generally involve only a small number of home visits, which aim at maximising the safety and autonomy of community‐dwelling clients. Knowing how community occupational therapists determine their interventions, i.e. their clinical reasoning, can improve intervention efficacy. However, occupational therapists are often uninformed about and neglect the importance of clinical reasoning, which could underoptimise their interventions. Aim: To synthesise current knowledge about community occupational therapists’ clinical reasoning. Method: A scoping study of the literature on community occupational therapists’ clinical reasoning was undertaken. Results: Fifteen textbooks and 25 articles, including six focussing on community occupational therapists’ clinical reasoning, were reviewed. Community occupational therapists’ clinical reasoning is influenced by internal and external factors. Internal factors include past experiences, expertise and perceived complexity of a problem. One of the external factors, practice context (e.g. organisational or cultural imperatives, physical location of intervention), particularly shapes community occupational therapists’ clinical reasoning, which is interactive, complex and multidimensional. However, the exact influence of many factors (personal context, organisational and legal aspects of health care, lack of resources and increased number of referrals) remains unclear. Conclusion: Further studies are needed to understand better the influence of internal and external factors. The extent to which these factors mould the way community occupational therapists think and act could have a direct influence on the services they provide to their clients. 相似文献

Background/aim: The aim of this paper is to describe the use of a structured interview methodology, the repertory grid technique, for investigating the clinical reasoning of an experienced occupational therapist in the domain of upper limb hypertonia as a result of brain injury.
Method: Repertory grid interviews were completed before and after exposure to a protocol designed to guide clinical reasoning and decision-making in relation to upper limb neurological rehabilitation. Data were subjected to both qualitative and quantitative analyses.
Results: Qualitative analysis focussed on clinical reasoning content. Common themes across the pre- and post-exposure interviews were the use of theoretical frameworks and practice models, the significance of clinical expertise, and discrimination of 'broad' and 'specific' aspects, as well as differentiation between 'therapist and client-related' aspects of the clinical situation. Quantitative analysis indicated that for both pre- and post-exposure repertory grids, clinical reasoning was structured in terms of two main concepts. In the pre-exposure grid, these were related to the therapist's role, and to the 'scope' of practice tasks (either broad or specific). In the post-exposure grid the two main concepts were upper limb performance, and client-centred aspects of the therapy process.
Conclusions: The repertory grid technique is proposed as an effective tool for exploring occupational therapy clinical reasoning, based on its capacity for accessing personal frames of reference, and elucidating both the meaning and the structure supporting clinical reasoning. 相似文献

Problem-based learning (PBL) in occupational therapy (OT) education has become increasingly important. However, the efficacy in identifying clinical reasoning skills has not been well researched. The purpose of this study was to evaluate the utilization of clinical reasoning by students in the USA and Scotland. Thirty OT students were videotaped during a PBL case. Responses were transcribed and compiled into 122 statements. The two primary investigators independently coded each of the responses into one of five categories: Procedural, Interactive, Conditional reasoning, N/A, or Other. Intraclass correlation coefficients reflected strong reliability between the two raters (ICC = 0.914). Results of this study indicated that the predominant form of clinical reasoning was procedural in nature (61%) followed by conditional reasoning (27%) and interactive reasoning (12%). Students in Scotland tended to use interactive reasoning more than the students in the USA. Further research is needed to explore educational models to foster clinical reasoning skills in occupational therapy students. 相似文献

BACKGROUND: To facilitate students' transition from basic, science-oriented, problem-based learning (PBL) to clinical reasoning-oriented PBL, the University of Geneva School of Medicine introduced a 12-week unit of Introduction to Clinical Reasoning (ICR) at the beginning of its fourth or clerkship year. PURPOSE: The aims of the present study were to determine, after 12 weeks in the ICR unit, to what extent students had: (1) identified the learning content set by the faculty while adapting to the hypothetico-deductive reasoning approach; (2) familiarised themselves with the clinical reasoning-oriented learning process, and (3) transferred and further developed this process during the clinical years. METHOD: Students' derived objectives from the problems were compared to the objectives preset by the faculty to determine acquisition of intended learning content. To assess their adaptation to the clinical reasoning-oriented PBL approach, students (n = 124) were asked to list and freely comment on aspects of the unit they felt most at ease with or had difficulty with, and to complete a questionnaire on the clinical reasoning process (CRP). The same questionnaire was administered 6 and 12 months later to assess the evolution of the students' self-perception during clerkships. RESULTS: On average, student objectives matched 62% of faculty objectives. Half of the missed (38%) objectives were in basic sciences. Students generated 16% additional objectives, also predominantly in the basic sciences category (41%). Free comments indicated that the difficulties perceived by students were very similar to those previously reported in studies on reasoning and errors, such as difficulty in gathering, interpreting and weighting relevant data, synthesising information, and organising it hierarchically. These results were confirmed with the CRP questionnaire administered at the end of the unit. For most of the competencies assessed on the CRP questionnaire, a gradual improvement was seen to have occurred by 6 and 12 months after the unit. CONCLUSIONS: To ease students' transition from the preclinical to clinical years, a learning unit should give them the opportunity to train their clinical reasoning processes on standardised and prototypical problems, before encountering real patients with more ill-structured problems during clerkships. Such a transitional structure should particularly emphasise a developed repertoire of problem representations, recognition of key findings and a hierarchical classification of working hypotheses. It should foster the creation of links between the acquired basic clinical knowledge and the diagnostic, management and therapy steps of problem solving. 相似文献

Summary Urine from sawmill workers exposed to -pinene, -pinene and -3-carene was collected and hydrolyzed with -glucuronidase at pH 5.0 for 24h at 37°C. After hydrolysis the urine was cleaned on a SEP-PAK C18 cartridge. The cartridge was eluted with n-heptane. The eluate was injected onto a gas chromatograph equipped with a 25-m (0.32-mm ID) SP-1000 capillary column. The major peak in the chromatogram was identified by GC-MS as trans-verbenol by electron impact at 70 eV. cis-Verbenol was also identified. These metabolites could not be detected in non-hydrolyzed urine from the exposed workers or in hydrolyzed urine from an unexposed individual. The recoveries of the verbenols from hydrolyzed urine were in the range of 85 to 94% and the metabolites were stable both in urine and in n-heptane after sample cleaning at –20°C for at least 12 weeks. We suggest that these metabolites are formed from -pinene by hydroxylation. 相似文献

Occupational exposure to lead (Pb) requires continuous surveillance to assure, as much as possible, safe and healthful working conditions. This study addresses the suitability of assessing Pb exposure in relevant workers using their exhaled breath condensate (EBC). This study enrolled workers of two different Pb processing industries characterized by moderate and high Pb exposure levels in the work environment, and a group of non-exposed individuals working in offices who served as baseline for Pb exposure. The EBC-Pb of workers reflected the Pb levels in the work environment of all three settings, although the relationship with B-Pb was not clear. The lack of correlation between EBC-Pb and B-Pb most probably indicates the time lag for Pb to enter in the two body pools. The EBC-Pb seems to reflect immediate exposure, providing a prompt signature of Pb in the environmental that may interact directly with the organ. By delivering short-term evaluation of exposure, EBC-Pb represents a clear advantage in biomonitoring and may become an interesting tool for estimating organ burden. 相似文献

Summary Hexahydrophthalic anhydride (HHPA) and methyltetrahydrophthalic anhydride (MTHPA) belong to the group of the acid anhydrides and, among other applications, are used in the production of epoxy resins. These substances are known as potent low-molecular allergens and induce predominantly type I allergies according to Coombs and Gell. We examined 110 employees exposed to HHPA and MTHPA. With all of them a RAST was carried out with the commercially available conjugates of phthalic anhydride (PA) and a skin prick test with 1% and 5% acetonic solutions of PA. In 109 of these sera a radio allergo sorbent test (RAST) was carried out with the not commercially available conjugates of HHPA and of MTHPA. With complaints connected with the workplace the working materials used (HHPA, MTHPA) were also checked by means of the skin prick test. With at least one positive immunological finding (in the RAST and/or skin prick test) in connection with complaints at the workplace, we performed a workplace-related inhalation test under experimental conditions. Specific IgE against acid anhydrides was detected in a total of 17 (15.4%) persons. In the challenge test, six (5.4%) sensitisations were shown to be clinically relevant. On inclusion of borderline positive findings with PA conjugates the RAST produced three false negative and one false positive finding compared with a RAST with HHPA and MTHPA conjugates. With the conjugates of trimellitic anhydride, in no case could specific IgE be detected. The skin prick test led, in comparison with the RAST, to three false positive and three false negative findings. With all clinically relevant sensitisations the skin prick test was regarded as positive. RASTs with conjugates of PA and skin prick tests with native acid anhydrides can, according to our investigations, validly ascertain workplace-related sensitisations to HHPA and MTHPA. 相似文献

目的 探讨田间作业中毒和口服有机磷农药中毒在临床表现及治疗上的差异.方法 回顾性分析我院2007年7月至2010年7月收治的85例中、重度急性有机磷农药中毒患者的临床资料,按中毒途径分为口服组(51例)和非口服组(34例),比较不同途径中毒后的临床表现、治疗特点及预后.结果 口服组中度中毒患者的肌颤肌痉挛和共济失调的发生率(86.4%、90.9%)均明显高于非口服组(50.0%、55.0%),差异有统计学意义(P<0.05,P<0.01);口服组重度中毒患者的肺水肿、肌颤肌痉挛及昏迷的发生率(100.0%、89.7%、93.1%)均明显高于非口服组(71.4%、64.3%、50.0%),差异有统计学意义(P<0.05 ).非口服组解毒时间[中度:(35.0±6.2)h、重度:(45.0±11.1)h]较口服组[中度:(49.0±7.7)h、重度:(77.0±10.3)h]明显缩短,差异有统计学意义(P<0.05).治疗后24、48、72 h,中、重度非口服组胆碱酯酶活力明显高于口服组,差异有统计学意义(P<0.05或P<0.01);中、重度非口服组的氯磷定用量、阿托品化用量及阿托品总量明显低于口服组,差异有统计学意义(P<0.05或P<0.01).结论 田间作业有机磷农药中毒在临床表现上与口服中毒不尽相同,且治疗的阿托品及氯磷定用量相对较少,胆碱酯酶活力恢复较快.Abstract: Objective To investigate the differences of clinical manifestation and therapy of organophosphorus pesticide poisoning (OPP) between oral exposure and occupational exposure in field work. Methods From July 2007 to July 2010, 85 patients with acute severe OPP were treated in a hospital, which were divided into oral poisoning group (51 cases) and non-oral poisoning group (34 cases). The differences of clinical manifestations, curative effects and prognosis between two groups were compared. Results The rates of myoclonus and ataxia in cases with moderate poisoning of oral poisoning group were 86.4% and 90.9%, which were significantly higher than those (50.0% and 55.0% ) of non-oral poisoning group (P<0.05 or P< 0.01). The rates of myoclonus, lung fluid and coma in cases with severe poisoning of oral poisoning group were 100.0%, 89.7% and 93.1%, respectively, which were significantly higher than those (71.4%, 64.3% and 50.0%) of non-oral poisoning group (P<0.05). The mean detoxification hours in cases with moderate poisoning and cases with severe poisoning of non-oral poisoning group were (35.0±6.2) and (45.0±11.1) hours which were significantly lower than those [(49.0±7.7) and (77.0±10.3) hours] in cases with moderate poisoning and cases with severe poisoning of oral poisoning group (P<0.05). In 24, 48 and 72 h after treatment, the cholinesterase (ChE) activities of non-oral poisoning group were higher than those of oral poisoning group (P< 0.05 or P<0.01). The used doses of pyraloxime methylchloride (PAM-Cl) or atropine and the used total dose of atropine in non-oral poisoning group were lower than those in oral poisoning group (P<0.05 or P<0.01). Conclusions The clinical manifestation of non-oral poisoning group is different from the clinical manifestation of oral poisoning group due to the high morbidity of OPP occurred at field site in summer. The used doses of atropine and PAM-Cl are less and the ChE activity recovers quickly for non-oral poisoning group. 相似文献
