Aiken (2007) [58] Review of US nurse supply and demand, trends in nurse immigration Does not specifically examine dual practice      
Alameddin et al. (2009a) [59] Examines impact of ‘just in time’ staffing policy in Ontario, Canada-and SARS outbreak; interviews with 13 nurse administrators. Examines impact of ‘just in time’ staffing policy in Ontario, Canada- fewer full time staff, more part time and casual staff and agency staff.    Reports higher costs, reduced surge capacity Fewer staff meant more overtime, stress related absenteeism increased.  
Alameddin et al. (2009b) [48] Tracking of 201,463 nurses registered with College of Ontario, 1993–2004 Focus is on all types of job, career move. Limited examination of casualisation      
Batch and Windsor (2009) [60] (a) Nursing has a higher rate of casualization than other professional and highly skilled workforces; (b) In Australia in 2011 in 2011, 47.5% of nurses were employed in non-standard work. Casualisation of work Australian hospitals The casualisation movement aims at creating a more flexible and cheaper nurse workforce   Part-time and casual nurses are marginalised and excluded - called hole-pluggers; Marginalisation is accepted and normalised as a trade-off for the flexibility of this modality  
Batch et al. (2015) [44] In 2007 the percentage of part-time and casual nurses, that is those nurses working less than 35 h per week, is 49.8% or almost half the nursing population    Inflexible rosters and unreasonable and unreasonable workloads, unavailability of full-time work in the area of choice. Lack of opportunities for professional development. Casual and part-time workers seen as peripheral workforce; Marginalisation of casual workers with consequences in career advancement; Implications in the quality of care due to lack of continuity of care and poor match of nurses’ skills to a workplace.   
Baumann et al. (2006) [30]   ‘Casualisation’ of the health workforce in Ontario following the SARS epidemic. Canada (Ontario).   Employing an unbalanced proportion of full time and casual nurses reduces flexibility of a hospital management, as these latter would be less available to cover for unforeseen needs   
Bhengu (2001) [19] 24 CC nurses, four focus groups, two hospitals in Durban, South Africa Second jobs via agency working Agency working in by public sector nurses in ICU, private sector hospitals (a) Demand for CC nurses in the private hospitals; (b) Salaries failing to keep pace with inflation; (c) Testing the experience of working in private sector Reported that ICU s in private sector hospitals totally dependent on agency moonlighters-so staffed by ‘strangers’ (a) Reported tiredness, more likely to go off work sick; (b) Risk of ‘habitual moonlighting’; (c) Psychosocial problems- different mix of ethnicity and language in private hospitals Private sector hospitals should develop clinical guidelines to ensure safety in hands of ‘strangers’
Brown (1999) [47] In 1996, female registered nurses (RNs) were moonlighting at the rate of about 12%; female advanced practice nurses (APNs) were moonlighting at the rate of about 24%. Second jobs held concurrently to the primary one; But also, second job not held continuously, i.e. irregularly.   On average, both RNs and APNs earn more on their second job then they do in their primary jobs. - The reason for the high rates of second-job holding among nurses relative to females in the general workforce appears to be a function of the nursing profession itself. Those with second jobs tend, on average, to work fewer hours per week on their primary jobs than those who only hold one job.   
Creegan et al. (2003) [36] 51.7% of nurses in Australia worked part-time in 1997 Casualisation and non-standard (part-time) forms of nursing profession Australia and references to the UK (a) Women are more likely to work on a part-time basis in Australia. Nursing is a predominantly female profession; (b) Casualization is particularly common among Licenced Practical Nurses (16.5%) (c) Casualization is more common for rural States (20%) (a) The hiring hospital has little control on quality and qualifications of agency nurses, used to top-up existing staff; (b) The savings associated with casualization of nursing are potentially large Casual nurses do not enjoy the same protection and support systems as permanent ones, nor opportunities for professional development (a) Need to understand better the shifting workforce patterns to improve management and planning of the nursing workforce; (b) To date, efforts have been directed towards recruiting more nurses in permanent positions. Better management of the casual workforce segment could represent an alternative policy.

Hipple (2010) [46] (a) Report on data from US Labor stats; (b) 6.3% of nurses had multiple jobs- higher for male nurses (9.5%, but small sample) Second jobs were in or out of health sector    Discusses possible impact of nurses working 12 h shifts- meaning they would have more free days for second jobs   
Knauth (2007) [32] 64% of nurses on 12 h nightshift and 45% of those on dayshift had a secondary job Extended periods of work across different professions (Moonlighting and secondary jobs) Nurses in 12 h night and day shifts   Increased sleepiness, difficulty of communicating with managers, increased risk of accidents driving home, increased absenteeism, reduced alertness   
Lane et al. (2009) [50] A broad based global review of nursing labour market, health systems and macroeconomic policy Has a brief section on dual practice as a ‘coping mechanism’ ‘Dual practices range from legitimate private practice to moonlighting and informal charges for patients.’   Dual practice ‘often results in conflict of interest, idleness and absenteeism. However, not all dual practices can be considered as corrupt or leading to predatorial behaviour, but the impact of these practices can significantly undermine health services provision and public trust’. ‘Abusive multi-employment can result in negative consequences for health workers as well as patients’.

(2009) [49]    Rural and community hospitals in the Hamilton Niagara area (Canada and US) It was reported by nurses that part-time and casual nurses often seek employment in other hospitals and long-term care homes to supplement their income Employment in multiple organisations contributes to scheduling issues because casual nurses are unavailable to fill vacant shifts   
Paina et al. (2014) [63] Five public sector ‘facility case studies’ in Kampala Uganda ‘Additional jobs’ (Focus was on all workers, not just nurses)    ‘Distinct challenges’ for local management in trying to manage internal dual practice opportunities, linked to opportunities to be involved in externally funded research projects within the hospital.   Variation between national – formal policy and local- invormal policy on allowing workers to have second jobs.
Portela et al. (2004) [39] 41.5% of public hospital nurses were moonlighters MJH was more common among nurses during 12 h night or day shifts Public hospitals in Brazil    Long (12 h) night shifts found to have a less taxing effect on nurses health than day ones.  
Ribeiro-Silva et al.(2006) [51] 33% Second job in another hospital or clinic (a) Public hospitals Brazil; (b) Registered nurses and nursing assistants (N = 144)   Those who had two jobs devoted more time to sleep/rest on the job (a) The less time devoted to leisure and personal needs among those who work more associated with quality of daily life; (b) Sleep on the job related to working on a second job.
