The hospital liaison process: identifying risk factors in postnatal multiparas.

Postnatal home visiting has been a routine part of the public health nurse's role in Canada for decades. Resource limitations in recent years have required Health Units to justify programming choices and in some cases have dictated a shift toward more intensive service provision to high risk clients. This study examined the screening accuracy of a tool developed for use by hospital liaison nurses to identify multiparas in need of home visiting. Results showed poor agreement between client information collected by the hospital liaison nurse and the assessment done by the PHN in the clients' home, even when explicit referral criteria were used. Changes are required in the referral process to effectively screen postnatal clients in need of further services.

Important considerations in the use of ethnicity as a study variable.

Ethnicity is widely used as a study variable by community health researchers. However, there is little consistency in the definition of ethnicity and the process by which ethnicity is assigned. Potential problems in the use of ethnicity as a study variable are discussed as well as suggestions for improvements.

Routine chest radiography after permanent pacemaker implantation: is it necessary?

BACKGROUND AND AIMS: Chest radiographs (CXRs) are performed routinely after permanent pacemaker implantation to identify pacemaker lead position and exclude pneumothorax. We assessed the clinical value and need for this procedure. DESIGN: Retrospective analysis of pacemaker data and CXRs following permanent pacemaker insertion between December 2002 and February 2004. MATERIALS AND METHODS: Post-procedural CXRs were available in 125/126 consecutive patients after either first endocardial pacemaker implantation or insertion of at least one new lead. Subclavian vein puncture was used for venous access in all cases. CXRs were examined to establish the incidence of pneumothorax and assess pacing lead positions. The clinical records were examined in all patients who had subsequent CXRs or a further pacemaker procedure to identify the indication for these and to establish whether CXR had influenced patient management. RESULTS: In total, 192 post-procedural CXRs were performed, either postero-anterior (PA) and/or lateral views. Ventricular and/or atrial pacing lead contour and electrode position was considered radiographically appropriate in 86% CXRs. Fourteen per cent of post-procedural radiographs were considered to have radiologically sub-optimal pacemaker lead positioning. None of the patients with these "abnormal" radiographs experienced subsequent pacemaker complications or had further radiographs recorded at a later date. Later repeat CXRs were performed in 16 patients (13%) but only 3 patients (2%) had pacing abnormalities as the primary indication. All three had satisfactory pacing lead position on initial post-implantation and later radiographs, but required further procedures for lead re-positioning. Iatrogenic pneumothorax occurred in one patient (incidence 0.8%) in our series. CXR confirmed the clinical diagnosis and allowed an assessment of size to guide treatment. CONCLUSION: Routine CXR after permanent pacemaker insertion is not necessary in uncomplicated cases with adequate pacing characteristics.

Tobacco use and ethnicity: the existing data gap.

Tobacco use contributes substantially to the burden of illness throughout the world. Significant efforts have been made to design health promotion programs for the prevention and cessation of tobacco use in North America. However, most of these programs have been planned and implemented on the basis of needs assessments conducted among the dominant cultural group. Evidence exists that lifestyle modification and tobacco cessation programs must be culturally relevant to ensure successful outcomes. A review of the literature from nursing, anthropological and epidemiological perspectives suggests that there is a paucity of data available on the largely culture-dependent values which influence the decision to use tobacco in those groups which comprise the Canadian multicultural mosaic. The interpretation of results from existing studies is limited by a number of recurrent methodological flaws. The implications of this review for future research and public health planning are discussed. The development of culturally appropriate programs directed at the prevention and cessation of tobacco use remains a significant challenge for health professionals.

Translating written material for community health research and service delivery: guidelines to enhance the process.

Translating health promotion and research material for cross-cultural use is costly and time-consuming. Methods to enhance the translation process are reviewed. The concept of equivalence and non-statistical approaches to achieve equivalence are presented. Utilization of these approaches may help strengthen the development of health promotion material and community health research instruments for use with ethnically diverse populations.

A randomized controlled trial of alternative approaches to community follow-up for postpartum women.

This three-group randomized controlled trial assessed the effectiveness of a postpartum public health nurse telephone visit on infant-care behaviours of primiparous women in Ottawa-Carleton. The impact of a clerk call on recruiting mothers to parent-baby groups was also described. Low risk primiparas were randomized into telephone visit, clerk call and control groups. At three months postpartum, there were no significant differences in infant-care behaviour scores among the study groups. Women who received the telephone visit had the highest parent-baby group attendance rates and among attenders, the highest rates of smoking during pregnancy, the least education, and lowest incomes. Analysis of variance revealed a significant interaction term between attendance at parent-baby groups and assigned study group. This effect disappeared after adjusting for age and education. The telephone visit was no more effective in producing the desired infant-care behaviour changes than a mailed out information package with or without a clerk phone call. However, the intervention did increase the utilization of parent-baby support groups by women who were more socioeconomically disadvantaged.
