Evaluation of a training intervention to improve cancer care in Zimbabwe: Strategies to Improve Kaposi Sarcoma Outcomes (SIKO), a prospective community-based stepped-wedge cluster randomized trial.

ABSTRACT:

Introduction

Most Zimbabweans access medical care through tiered health systems. In 2013, HIV care was decentralized to primary care clinics; while oncology care remained centralized. Most persons in Zimbabwe with Kaposi sarcoma (KS) are diagnosed late in their disease, and the prognosis is poor. Little is known about whether educational interventions could improve KS outcomes in these settings.

Methods

Interventions to improve KS detection and management were evaluated at eight Zimbabwe primary care sites (four rural/four urban) that provided HIV care. Interventions included a standardized KS clinical evaluation tool, palliative care integration, standardized treatment and improved consultative services. Interventions were implemented between February 2013 and January 2016 using a randomized stepped-wedge cluster design. Sites were monitored for KS diagnosis rates and KS outcomes, including early diagnosis (T0 vs. T1 tumour stage), participant retention and mortality. Analyses controlled for within-clinic correlations.

Results

A total of 1102 persons with suspected KS (96% HIV positive) were enrolled: 47% incident (new diagnosis), 20% prevalent (previous diagnosis) and 33% determined as not KS. Early (T0) diagnosis increased post-intervention, though not significant statistically (adjusted odds ratio [aOR] = 1.48 [95% confidence interval (95% CI): 0.66-3.79], p = 0.37). New KS diagnosis rates increased 103% (95% CI: 11-273%), p = 0.02) post-intervention; although paired with an increased odds of incorrectly diagnosing KS (aOR = 2.08 [95% CI: 0.33-3.24], p = 0.001). Post-intervention, non-significant decreases in 90-day return rates (adjusted hazard ratio [aHR] = 0.69 [95% CI: 0.38-1.45], p = 0.21) and survival (aHR = 1.36 [95% CI: 0.85-2.20], p = 0.20) were estimated.

Conclusions

KS training interventions at urban and rural Zimbabwe decentralized primary care clinics significantly increased overall and incorrect KS diagnosis rates, but not early KS diagnosis rates, 90-day return rates or survival.

Project description:Youth living with HIV (YLHIV) report that negative interactions with health care workers (HCWs) affects willingness to return to care. This stepped wedge randomized trial evaluated effectiveness of a standardized patient actor (SP) HCW training intervention on adolescent engagement in care in Kenya. HCWs caring for YLHIV at 24 clinics received training on adolescent care, values clarification, communication, and motivational interviewing, with 7 SP encounters followed by facilitated feedback of videotaped interactions. Facilities were randomized to timing of the intervention. The primary outcome was defined as return within 3 months after first visit (engagement) among YLHIV who were either newly enrolled or who returned to care after >3 months out of care. Visit data was abstracted from electronic medical records. Generalized linear mixed models adjusted for time, being newly enrolled, and clustering by facility. YLHIV were surveyed regarding satisfaction with care. Overall, 139 HCWs were trained, and medical records were abstracted for 4,595 YLHIV. Median YLHIV age was 21 (IQR 19-23); 82% were female, 77% were newly enrolled in care, and 75% returned within 3 months. Half (54%) of trained HCWs remained at their clinics 9 months post-training. YLHIV engagement improved over time (global Wald test, p = 0.10). In adjusted models, the intervention showed no significant effect on engagement [adjusted Prevalence Ratio (aPR) = 0.95, 95% Confidence Interval (CI): 0.88-1.02]. Newly enrolled YLHIV had significantly higher engagement than those with prior lapses in care (aPR = 1.18, 95%CI: 1.05-1.33). Continuous satisfaction with care scores were significantly higher by wave 3 compared to baseline (coefficient = 0.38, 95%CI: 0.19-0.58). Despite provider skill improvement, there was no effect of SP training on YLHIV engagement in care. This may be due to temporal improvements or turnover of trained HCWs. Strategies to retain SP-training benefits need to address HCW turnover. YLHIV with prior gaps in care may need more intensive support.

Project description:ObjectivesTo examine whether primary care outreach facilitation improves the quality of care for general practice patients from refugee backgrounds.DesignPragmatic, cluster randomised controlled trial, with stepped wedge allocation to early or late intervention groups.Setting, participants31 general practices in three metropolitan areas of Sydney and Melbourne with high levels of refugee resettlement, November 2017 - August 2019.InterventionTrained facilitators made three visits to practices over six months, using structured action plans to help practice teams optimise routines of refugee care.Major outcome measureChange in proportion of patients from refugee backgrounds with documented health assessments (Medicare billing). Secondary outcomes were refugee status recording, interpreter use, and clinician-perceived difficulty in referring patients to appropriate dental, social, settlement, and mental health services.ResultsOur sample comprised 14 633 patients. The intervention was associated with an increase in the proportion of patients with Medicare-billed health assessments during the preceding six months, from 19.1% (95% CI, 18.6-19.5%) to 27.3% (95% CI, 26.7-27.9%; odds ratio, 1.88; 95% CI, 1.42-2.50). The impact of the intervention was greater in smaller practices, practices with larger proportions of patients from refugee backgrounds, recent training in refugee health care, or higher baseline provision of health assessments for such patients. There was no impact on refugee status recording, interpreter use increased modestly, and reported difficulties in refugee-specific referrals to social, settlement and dental services were reduced.ConclusionsLow intensity practice facilitation may improve some aspects of primary care for people from refugee backgrounds. Facilitators employed by local health services could support integrated approaches to enhancing the quality of primary care for this vulnerable population.Trial registrationAustralian New Zealand Clinical Trials Registry, ACTRN12618001970235 (retrospective).

Project description:Background P2Y12 inhibitor medications are critical following percutaneous coronary intervention (PCI); however, adherence remains suboptimal. Our objective was to assess the effectiveness of a multifaceted intervention to improve P2Y12 inhibitor adherence following PCI. Methods and Results This was a modified stepped wedge trial of 52 eligible hospitals, of which 15 were randomly selected and agreed to participate (29 hospitals declined, and 8 eligible hospitals were not contacted). At each intervention hospital, patient recruitment occurred for 6 months and enrolled patients were followed up for 1 year after PCI. Three control groups were used: patients at intervention hospitals undergoing PCI (1) before the intervention period (preintervention); (2) after the intervention period (postintervention); or (3) at the 8 hospitals not contacted (concurrent controls). The intervention consisted of 4 components: (1) P2Y12 inhibitor delivered to patients' bedside after PCI; (2) education on importance of P2Y12 inhibitors; (3) automated reminder telephone calls to refill medication; and (4) outreach to patients if they delayed refilling P2Y12 inhibitor. The primary outcomes were as follows: (1) proportion of patients with delays filling P2Y12 inhibitor at hospital discharge and (2) proportion of patients who were adherent in the year after PCI using pharmacy refill data. Primary analysis compared intervention with preintervention control patients. There were 1377 (intent-to-treat) potentially eligible patients, of whom 803 (per protocol) were approached at intervention sites versus 5910 preintervention, 2807 postintervention, and 4736 concurrent control patients. In the intent-to-treat analysis, intervention patients were less likely to delay filling P2Y12 at hospital discharge (-3.4%; 98.3% CI, -1.2% to -5.6%) and more likely to be adherent to P2Y12 (4.1%; 98.3% CI, 1.0%-7.1%) at 1 year, but had more clinical events (3.2%; 98.3% CI, 2.3%-4.1%) driven by repeated PCI compared with preintervention patients. In post hoc analysis looking at myocardial infarction, stroke, and death, intervention patients had lower event rates compared with preintervention patients (-1.7%; 98.3% CI, -2.3% to -1.1%). Conclusions A 4-component intervention targeting P2Y12 inhibitor adherence was difficult to implement. The intervention produced mixed results. It improved P2Y12 adherence, but there was also an increase in repeat PCI. Registration URL: https://www.clinicaltrials.gov; Unique identifier: NCT01609842.

Project description:BACKGROUND:Newborn mortality in Cambodia remains high, with sepsis and complications of delayed care-seeking important contributing factors. Intervention study objectives were to improve infection control behavior by staff in health centers; improve referral of sick newborns; increase recognition of danger signs, and prompt care-seeking at an appropriate health facility; and appropriate referral for sick newborns by mothers and families of newborn infants. METHODS:The stepped-wedge cluster-randomized controlled trial took place in rural Cambodia from February 2015 to November 2016. Sixteen clusters consisted of public health center catchment areas serving the community. The intervention included health center staff training and home visits to mothers by community health volunteers within 24 hours of birth and on days 3 and 7 after delivery, including assessment of newborns for danger signs and counselling mothers. The trial participants included women who had recently delivered a newborn who were visited in their homes in the first week, as well as health center staff and community volunteers who were trained in newborn care. Women in their last trimester of pregnancy greater than 18 years of age were recruited and were blinded to their group assignment. Mothers and caregivers (2494) received counseling on handwashing practices, breastfeeding, newborn danger signs, and prompt, appropriate referral to facilities. RESULTS:Health center staff in the intervention group had increased likelihood of hand washing at recommended key moments when compared with the control group, increased knowledge of danger signs, and higher recall of at least three hygiene messages. Of mother/caregiver participants at 14 days after delivery, women in the intervention group were much more likely to know at least three danger signs and to have received messages on care-seeking compared with controls. CONCLUSIONS:The intervention improved factors understood to be associated with newborn survival and health. Well-designed training, followed by regular supervision, enhanced the knowledge and self-reported behavior of health staff and health volunteers, as well as mothers' own knowledge of newborn danger signs. However, further improvement in newborn care, including care-seeking for illness and handwashing among mothers and families, will require additional involvement from broader stakeholders in the community.

Project description:BackgroundPractice facilitation has been associated with meaningful improvements in disease prevention and quality of patient care. Using practice facilitation, the Improved Delivery of Cardiovascular Care (IDOCC) project aimed to improve the delivery of evidence-based cardiovascular care in primary care practices across a large health region. Our goal was to evaluate IDOCC's impact on adherence to processes of care delivery.MethodsA pragmatic stepped wedge cluster randomized trial recruiting primary care providers in practices located in Eastern Ontario, Canada (ClinicalTrials.gov: NCT00574808). Participants were randomly assigned by region to one of three steps. Practice facilitators were intended to visit practices every 3-4 (year 1-intensive) or 6-12 weeks (year 2-sustainability) to support changes in practice behavior. The primary outcome was mean adherence to indicators of evidence-based care measured at the patient level. Adherence was assessed by chart review of a randomly selected cohort of 66 patients per practice in each pre-intervention year, as well as in year 1 and year 2 post-intervention.ResultsEighty-four practices (182 physicians) participated. On average, facilitators had 6.6 (min: 2, max: 11) face-to-face visits with practices in year 1 and 2.5 (min: 0 max: 10) visits in year 2. We collected chart data from 5292 patients. After adjustment for patient and provider characteristics, there was a 1.9 % (95 % confidence interval (CI): -2.9 to -0.9 %) and 4.2 % (95 % CI: -5.7 to -2.6 %) absolute decrease in mean adherence from baseline to intensive and sustainability years, respectively.ConclusionsIDOCC did not improve adherence to best-practice guidelines. Our results showed a small statistically significant decrease in mean adherence of questionable clinical significance. Potential reasons for this result include implementation challenges, competing priorities in practices, a broad focus on multiple chronic disease indicators, and use of an overall index of adherence. These results contrast with findings from previously reported facilitation trials and highlight the complexities and challenges of translating research findings into clinical practice.Trial registrationClinicalTrials.gov NCT00574808.
