The effect of communication skills training on patient outcomes in cancer care: a systematic review of the literature.

The objective of this review was to determine whether communication training for healthcare professionals (HCP), including nurses and medical doctors, in cancer care improves patient outcomes. Eligible studies with a focus on patient outcomes and a controlled or single group pretest-posttest design were identified according to Cochrane Collaboration Guidelines. Seven studies, encompassing 10 papers and involving five randomised controlled trials, were included. Studies involved 411 HCP, including a total of 1677 encounters with adult cancer patients. Forty-nine papers were excluded, primarily because no patient outcomes were reported. Regarding patient satisfaction outcomes, estimated effects in favour of communication training ranged from 0.07 (95% CI: -0.30 to 0.44) for satisfaction with information and support to 0.70 (95% CI: 0.16 to 1.24) for satisfaction with assessment of concerns. No evidence was found for the effectiveness of communication training on patient distress outcomes. We concluded that the current review reveals inconclusive evidence to prove the effectiveness of communication training on patient satisfaction and patient distress. More high-quality studies are needed.

The effectiveness of commonly used mouthwashes for the prevention of chemotherapy-induced oral mucositis: a systematic review.

Daily chlorhexidine mouthwash is often recommended for preventing chemotherapy-induced oral mucositis. Povidone-iodine, NaCl 0.9%, water salt soda solution and chamomile mouthwash are also recommended. However, the effectiveness of these mouthwashes is unclear. Therefore, we performed a systematic review to assess the effectiveness of mouthwashes in preventing and ameliorating chemotherapy-induced oral mucositis. Based on study quality, three out of five randomized controlled trials were included in a meta-analysis. The results failed to detect any beneficial effects of chlorhexidine as compared with sterile water, or NaCl 0.9%. Patients complained about negative side-effects of chlorhexidine, including teeth discoloration and alteration of taste in two of the five studies on chlorhexidine. The severity of oral mucositis was shown to be reduced by 30% using a povidone-iodine mouthwash as compared with sterile water in a single randomized controlled trial. These results do not support the use of chlorhexidine mouthwash to prevent oral mucositis.

Psychosocial interventions for patients with advanced cancer - a systematic review of the literature.

Advanced cancer is associated with emotional distress, especially depression and feelings of sadness. To date, it is unclear which is the most effective way to address these problems. This review focuses on the effects of psychosocial interventions on the quality of life (QoL) of patients with advanced cancer. It was hypothesised that patients will benefit from psychosocial interventions by improving QoL, especially in the domain of emotional functioning. The review was conducted using systematic review methodology involving a systematic search of the literature published between 1990 and 2002, quality assessment of included studies, systematic data extraction and narrative data synthesis. In all, 10 randomised controlled studies involving 13 trials were included. Overall interventions and outcome measures across studies were heterogeneous. Outcome measures, pertaining to the QoL dimension of emotional functioning, were most frequently measured. A total of 12 trials evaluating behaviour therapy found positive effects on one or more indicators of QoL, for example, depression. The results of the review support recommendation of behaviour therapy in the care of patients with advanced cancer.

Postulating a dermal pathway for exposure to anti-neoplastic drugs among hospital workers. Applying a conceptual model to the results of three workplace surveys.

Dermal exposure to anti-neoplastic drugs has been suggested as a potentially important route of exposure of hospital workers. Three small-scale workplace surveys were carried out in several hospitals focusing on contamination by leakage from IV infusion systems; contamination by spilled urine of patients treated with anti-neoplastic drugs and particulate phase anti-neoplastic drugs in the air of outpatient and nursing clinics. A new visual scoring technique using a fluorescent tracer was developed. The method showed a very low limit of detection (0.02 microl of contamination) and a very high inter-observer agreement (ICC=0.99). Evaluation of IV systems and connectors showed distinct differences between the systems. It was estimated that 0.5-250 microg of a drug can become available for contamination during each infusion. Differences in average contamination between nurses were negligible in the experimental set-up. Widespread and frequent contamination due to spillage of contaminated urine was revealed and appeared not to be restricted to the patient's room. Airborne particulate concentrations went undetected for 80% of the measurements. However, in a few cases concentrations up to 2 ng/m(3) of cyclophosphamide were measured predominantly in a room of a patient treated with this anti-neoplastic drug. Based on these results and a recently proposed conceptual model for dermal exposure a most likely exposure scenario was postulated both for nurses involved in administering drugs and nurses caring for treated patients. Estimation of all relevant mass transport rates will be a challenge for the near future.
