Impact of organizational factors on adherence to laboratory testing protocols in adult HIV care in Lusaka, Zambia.

Background: Previous operational research studies have demonstrated the feasibility of large-scale public sector ART programs in resource-limited settings. However, organizational and structural determinants of quality of care have not been studied.

Methods: We estimate multivariate regression models using data from 13 urban HIV treatment facilities in Zambia to assess the impact of structural determinants on health workers' adherence to national guidelines for conducting laboratory tests such as CD4, hemoglobin and liver function and WHO staging during initial and follow-up visits as part of Zambian HIV care and treatment program.

Modeling the impact of integrating HIV and outpatient health services on patient waiting times in an urban health clinic in Zambia.

Background: Rapid scale up of HIV treatment programs in sub-Saharan Africa has refueled the long-standing health policy debate regarding the merits and drawbacks of vertical and integrated system. Recent pilots of integrating outpatient and HIV services have shown an improvement in some patient outcomes but deterioration in waiting times, which can lead to worse health outcomes in the long run.

Methods: A pilot intervention involving integration of outpatient and HIV services in an urban primary care facility in Lusaka, Zambia was studied.

The joint effects of personality and workplace social exchange relationships in predicting task performance and citizenship performance.

This field study examines the joint effects of social exchange relationships at work (leader-member exchange and team-member exchange) and employee personality (conscientiousness and agreeableness) in predicting task performance and citizenship performance. Consistent with trait activation theory, matched data on 230 employees, their coworkers, and their supervisors demonstrated interactions in which high quality social exchange relationships weakened the positive relationships between personality and performance. Results demonstrate the benefits of consonant predictions in which predictors and outcomes are matched on the basis of specific targets.

"All in a day's work": how follower individual differences and justice perceptions predict OCB role definitions and behavior.

The authors draw on theories of social exchange and prosocial behavior to explain how employee perceptions of procedural justice and individual differences in reciprocation wariness, empathic concern, and perspective taking function jointly as determinants of organizational citizenship behavior (OCB) role definitions and behavior. As hypothesized, empirical findings from a field study show both direct and interactive effects of procedural justice perceptions and individual differences on OCB role definition. In turn, OCB role definitions not only predict OCB directly but also moderate the effects of procedural justice perceptions on OCB.
