A literature review exploring the perceived impact, challenges and barriers of advanced and consultant practice in therapeutic radiography

OBJECTIVES

This review seeks to explore the perceived impact, challenges and barriers of advanced and consultant radiographer roles on staff, patients and healthcare. A systematic approach was used to search for and identify suitable literature for review. All appropriate literature was critically appraised and analysed qualitatively by thematic analysis. The results were integrated to give an overall evaluation of the impact of advanced and consultant practice within Therapeutic Radiography.

KEY FINDINGS

The literature found eleven studies that met the inclusion criteria and after critical appraisal, all were included in the analysis. Five key themes emerged from the analysis which is in keeping with the literature: education, quality of working life, patient care, benefit to healthcare and implementation obstacles.

CONCLUSION

Most advanced and consultant radiographers felt unprepared for these roles and the education requirements were varied and misunderstood. It was well documented that the advanced and consultant radiographer found great satisfaction from these roles and felt that it benefitted the patients as well as themselves and their career. Advanced and consultant roles benefitted patients by streamlining pathways and increasing satisfaction and there was a clear benefit to healthcare due to time and cost savings. The implementation obstacles focused around a lack of understanding and support from colleagues. There is a positive impact from advanced and consultant roles in therapeutic radiography to patients, staff and the healthcare system.

IMPLICATIONS FOR PRACTICE

There are challenges with respect to educational requirements, implementation obstacles and understanding of these roles which need to be addressed. There needs to be more education about the benefits of these roles so that they are encouraged and the staff are supported.

Exclusive breastfeeding reduces acute respiratory infection and diarrhea deaths among infants in Dhaka slums

OBJECTIVES

To describe breastfeeding practices and investigate the influence of exclusive breastfeeding in early infancy on the risk of infant deaths, especially those attributable to respiratory infections (ARI) and diarrhea.

METHODS

A prospective observational study was conducted on a birth cohort of 1677 infants who were born in slum areas of Dhaka in Bangladesh and followed from birth to 12 months of age. After enrollment at birth, the infants were visited 5 more times by 12 months of age. Verbal autopsy, based on a structured questionnaire, was used to assign a cause to the 180 reported deaths. Proportional hazards regression models were used to estimate the effect of breastfeeding practices, introduced as a time-varying variable, after accounting for other variables, including birth weight. Overall neonatal, postneonatal and infant mortality, and mortality attributable to ARI and diarrhea were measured.

RESULTS

The proportion of infants who were breastfed exclusively was only 6% at enrollment, increasing to 53% at 1 month and then gradually declining to 5% at 6 months of age. Predominant breastfeeding declined from 66% at enrollment to 4% at 12 months of age. Very few infants were not breastfed, whereas the proportion of partially breastfed infants increased with age. Breastfeeding practices did not differ between low and normal birth weight infants at any age. The overall infant mortality rate was 114 deaths per 1000 live births. Compared with exclusive breastfeeding in the first few months of life, partial or no breastfeeding was associated with a 2.23-fold higher risk of infant deaths resulting from all causes and 2.40- and 3.94-fold higher risk of deaths attributable to ARI and diarrhea, respectively.

CONCLUSION

The important role of appropriate breastfeeding practices in the survival of infants is clear from this analysis. The reduction of ARI deaths underscores the broad-based beneficial effect of exclusive breastfeeding in prevention of infectious diseases beyond its role in reducing exposure to contaminated food, which may have contributed to the strong protection against diarrhea deaths.

Early introduction of solid foods among urban African-American participants in WIC

OBJECTIVE

To compare infant feeding practices among low-income, urban, African-American women enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) with current recommendations for infant feeding.

DESIGN

Longitudinal follow-up of women and their infants who participated in a WIC-based breast-feeding promotion project. Women enrolled prenatally at or before 24 weeks of gestation were followed up until 16 weeks postpartum.

SUBJECTS/SETTING

Two hundred seventeen African-American WIC participants in an urban area.

METHODS

Data related to infant feeding practices were collected by interviewers who used a structured questionnaire to determine when nonmilk liquids or solids were introduced to the infant. Reported practices were compared with current recommendations.

STATISTICAL ANALYSIS PERFORMED

Contingency table analysis, including chi 2 tests, and multivariate analysis using logistic regression.

RESULTS

By 7 to 10 days postpartum, approximately a third of infants were receiving some nonmilk liquids or solids; this escalated to 77% by 8 weeks and 93% by 16 weeks postpartum. Women breast-feeding exclusively (i.e., not adding nonmilk liquids or solids) were least likely, and women providing mixed feeding (breast milk and formula) were more likely, than women feeding formula exclusively to introduce nonmilk liquids and solids at each data collection time period.

APPLICATIONS/CONCLUSIONS

WIC participants who receive instruction about infant feeding nutrition are no more likely than mothers who do not participate in WIC to follow infant feeding guidelines recommended by the American Academy of Pediatrics in regard to the time when solids should be introduced to infants' diet. Our findings suggest the need for WIC to implement more powerful and innovative educational and motivational strategies to help mothers delay the introduction of nonmilk liquids and solid foods until their infants are 4 to 6 months old, as recommended.

Neighbourhood differences in diet: the Atherosclerosis Risk in Communities (ARIC) Study

STUDY OBJECTIVE

To investigate whether neighbourhood characteristics are related to dietary patterns independently of individual level variables.

DESIGN

A cross sectional analysis of the relation between neighbourhood median household income and food and nutrient intakes, before and after adjustment for individual level variables.

SETTING

Four United States communities (Washington Co, MD; Suburban Minneapolis, MN; Forsyth Co, NC, and Jackson, MS).

PARTICIPANTS

13,095 adults aged 45 to 64 years participating in the baseline examination of the Atherosclerosis Risk in Communities (ARIC) Study, a prospective study of atherosclerosis.

MEASUREMENTS AND MAIN RESULTS

Information on diet and individual level income was obtained from the baseline examination of the ARIC Study. Diet was assessed using a semi-quantitative food frequency questionnaire. Information on neighbourhood (census defined block groups) median household income was obtained from the 1990 US Census. Multilevel models were used to account for the multilevel structure of the data. Living in lower income neighbourhoods was generally associated with decreased energy adjusted intake of fruits, vegetables, fish, and increased intake of meat. Patterns generally persisted after adjustment for individual level income, but were often not statistically significant. Inconsistent associations were recorded for the intake of saturated fat, polyunsaturated fat, and cholesterol. Overall, individual level income was a more consistent predictor of diet than neighbourhood income.

CONCLUSION

Despite limitations in the definition and characterisation of neighbourhoods, this study found consistent (albeit small) differences across neighbourhoods in food intake, suggesting that more in depth research into potential neighbourhood level determinants of diet is warranted.

Variation in early neonatal mortality for different types of fetal growth retardation

Birth and first-48-hr death records were analyzed for 10,024 liveborn infants in Mexico City and 12,786 liveborn infants in Santa Cruz, Bolivia. The objective of the analysis was to characterize the early postnatal mortality rates for different types of fetal growth retardation and prematurity. Infants who were delivered prior to 37 weeks of gestation had 23-100 times the mortality risk of infants born at full term and normal weight. Light-for-gestational-age infants (birth weight less than 2,900 g) were further divided into proportionately growth-retarded with normal Rohrer's index (weight/height) and disproportionately growth-retarded with low Rohrer's index. The proportionately growth-retarded infant had nearly twice the mortality of the full-term, appropriate-weight infants, whereas the disproportionately growth-retarded infants had 2.9-5.7 times the mortality rate of the full-term, appropriate-weight infants. There were some differences between samples in mortality rates and prevalence of the different classes of small infants, but the pattern of mortality within samples was consistent between samples.
