“…to enable people and show respect for them, as is done in person-centered care [19]. Another important aspect is to adapt the instrument to those who can provide the requested information [31], in this case the staff. We found two instruments from sectors other than industry that we regarded as interesting candidates for further development in the present study: Roszell’s [29] and Malmbrandt and Åhlström’s [28] instruments.…”

BackgroundDuring the past decade, the concept of Lean has spread rapidly within the healthcare sector, but there is a lack of instruments that can measure staff’s perceptions of Lean adoption. Thus, the aim of the present study was to develop a questionnaire measuring Lean in healthcare, based on Liker’s description of Lean, by adapting an existing instrument developed for the service sector.MethodsA mixed-method design was used. Initially, items from the service sector instrument were categorized according to Liker’s 14 principles describing Lean within four domains: philosophy, processes, people and partners and problem-solving. Items were lacking for three of Liker’s principles and were therefore developed de novo. Think-aloud interviews were conducted with 12 healthcare staff from different professions to contextualize and examine the face validity of the questionnaire prototype. Thereafter, the adjusted questionnaire’s psychometric properties were assessed on the basis of a cross-sectional survey among 386 staff working in primary care.ResultsThe think-aloud interviews led to adjustments in the questionnaire to better suit a healthcare context, and the number of items was reduced. Confirmatory factor analysis of the adjusted questionnaire showed a generally acceptable correspondence with Liker’s description of Lean. Internal consistency, measured using Cronbach’s alpha, for the factors in Liker’s description of Lean was 0.60 for the factor people and partners, and over 0.70 for the three other factors. Test-retest reliability measured by the intra-class correlation coefficient ranged from 0.77 to 0.88 for the four factors.ConclusionsWe designed a questionnaire capturing staff’s perceptions of Lean adoption in healthcare on the basis of Liker’s description. This Lean in Healthcare Questionnaire (LiHcQ) showed generally acceptable psychometric properties, which supports its usability for measuring Lean adoption in healthcare. We suggest that further research focus on verifying the usability of LiHcQ in other healthcare settings, and on adjusting the instrument if needed.Electronic supplementary materialThe online version of this article (doi:10.1186/s12913-017-2163-x) contains supplementary material, which is available to authorized users.

“…Bearing in mind that Bauchi State has a total population of 6,056,519 people, 3 geopolitical zones, 20 Local Government Areas (LGAs), and 196 directly observed treatment, short-course (DOTS) treatment centers, a representative sample of these 53 caregivers of CTB cases were obtained using the multi-staged sampling technique. These were proportionally contributed by each of the 8 randomly selected DOTS centers through systematic random sampling technique [25].…”

Background: In Nigeria, childhood tuberculosis (TB), a debilitating and deadly disease, is highly prevalent and case reporting is poor due to weak health systems. Globally, children account for at least 10 percent of the TB burden, yet they remain neglected in TB prevention and control efforts. Research studies integrating family and community-centered strategies have been recommended by stakeholders to address the paucity of current local prevention and management strategies for childhood TB. Study Design: Observational study. Methods: This quantitative cross-sectional study explored the relationship between caregivers' quality of life (QOL) and the reporting of TB in their children aged 0 -14 years. Using the abbreviated version of World Health Organization's (WHO) QOL tool, the WHOQOL-BREF, data were collected individually in a face-to-face setting from caregivers (n = 47) whose children had been diagnosed with TB in Bauchi State, Northeastern Nigeria, over a 5-year period. Data were collected in the same manner from another set of caregivers of children without TB (n = 47) within the same period and setting. Results: Logistic regression indicated a statistically significant relationship (p < 0.001) between the caregivers' QOL and the reporting of childhood TB. Conclusion: This finding underscores the need to identify the factors that positively impact the QOL of caregivers of childhood TB cases. It also reflects the importance of integrating QOL interventions as part of TB control programs seeking to improve childhood TB reporting. This can mitigate the disease burden in vulnerable age-groups living in resource limited settings, thereby contributing to positive social change in the society.

“…Patient representatives and GPs were recruited using a snowball sampling method. 27 One of the coresearchers proposed nine patient representatives from local mental health service user organisations. These nine representatives were then contacted individually and invited to participate in this study by email and telephone; two of the nine representatives declined to participate.…”

BackgroundShared understanding between GPs and hospital specialists concerning when patients need specialised mental health care is important to ensure patients receive appropriate care. The large amount of rejected referrals often indicates a lack of such shared understanding.AimTo explore how patient representatives, GPs, and mental health specialists understand ‘need for specialised mental health care’, meaning that primary care is no longer sufficient.Design & settingThis qualitative study was conducted in western Norway. The study has a service user-involved research design in which GPs and patient representatives participated in all stages of the research process.MethodSix semi-structured focus group interviews were conducted. The groups were homogenous as they included only the perspectives of either GPs, mental health specialists, or patient representatives. Data were analysed using thematic analysis.ResultsThe need for specialised mental health care was assessed using two continuums: (a) the patient’s level of functioning and symptoms; and (b) characteristics of the healthcare system and the patient’s informal support networks. Assessment along these continuums were often overruled by the evaluation of expected usefulness of specialised mental health care. In addition, all participants reported they often adapted their definition of need to fit other stakeholders’ interpretations of need.ConclusionEvaluation of need for specialised mental health care is complex and depends on several factors. This may explain some of the current challenges that exist with regard to equity and timely access to appropriate healthcare interventions.
