Kidney Patient Care in Disasters: Lessons from the Hurricanes and Earthquake of 2005

The active 2005 hurricane season alerted Americans to the pressing need for a more effective response to mass casualty incidents. The kidney patient community was particularly affected. Ninety-four dialysis facilities in the Gulf Coast states closed for at least 1 wk in the aftermath of Hurricane Katrina, and additional units were affected by evacuation of dialysis patients. Dialysis units along the Gulf Coast were also affected by Hurricanes Rita and Wilma. Existing emergency response plans were inadequate in providing continuity of care for kidney patients. The Kashmir, South Asia, earthquake of October 2005 killed 97,000 individuals. Building collapse was associated with widespread crush injury, and many patients required temporary hemodialysis. Several regions of the United States have the potential for catastrophic earthquakes. The Kidney Community Emergency Response Coalition has recently issued recommendations for patients, dialysis facilities, and providers, with a goal to improve care of kidney patients in future domestic disasters. With suitable planning, the nephrology community can do much to ensure the continuity of medical care for kidney patients in the face of a wide range of possible natural and human-made disasters.

Missed dialysis sessions and hospitalization in hemodialysis patients after Hurricane Katrina

In order to evaluate the factors that contributed to missed dialysis sessions and increased hospitalizations of hemodialysis patients after Hurricane Katrina, we contacted 386 patients from 9 New Orleans hemodialysis units. Data were collected through structured telephone interviews on socio-demographics, dialysis factors, and evacuation characteristics. Overall, 44% of patients reported missing at least one and almost 17% reported missing 3 or more dialysis sessions. The likelihood of missing 3 or more sessions was greater for those whose dialysis vintage was less than 2 years compared to those for whom it was 5 or more years, who had 38 or fewer billed dialysis sessions compared to those who had 39 or more in the 3 months before the storm, who lived alone before the storm, who were unaware of their dialysis facilitys emergency plans, who did not evacuate prior to hurricane landfall, and who were placed in a shelter. The adjusted odds ratio of hospitalization among patients who missed 3 or more compared to those who did not miss any dialysis sessions was 2.16 (95% CI: 1.05-4.43). These findings suggest that when preparing for future disasters more emphasis needs to be placed on patient awareness and early execution of emergency plans.

Kidney Patient Care in Disasters: Emergency Planning for Patients and Dialysis Facilities

The catastrophic 2005 hurricane season alerted Americans to the need for a more effective response to mass casualty incidents. To address the needs of the nephrology community, the Kidney Community Emergency Response Coalition (KCERC) was formed, with representatives from more than 50 governmental agencies and private organizations. After completing phase 1 of its work, the KCERC issued recommendations for patients, dialysis units, and providers. During phase 2, the KCERC will promote implementation of those recommendations. During a disaster, the KCERC will host a daily conference call on which dialysis facilities, the End-Stage Renal Disease Networks, and emergency response officials will coordinate disaster response. Predisaster preparation for kidney patients should stress identification of alternative dialysis facilities, education about the renal emergency diet, and plans for early evacuation from the disaster area and for evacuating with medical documents and medications. Dialysis facilities are required to have a disaster plan; regular revision and rehearsal are essential. Critical issues for dialysis facilities include identification of partner facilities, a robust communications plan that takes into account the limitations of telephones and broadband access, staff shortages in the face of a possible influx of new patients, the delivery of service in the face of compromised utilities (water, power), and the recovery of a dialysis facility that experiences flooding or structural damage. A timeline to safety for dialysis patients can be visualized; if specific tasks are accomplished at each disaster stage, then it is likely that the health of these vulnerable patients can be protected.

Psychosocial Status of Hemodialysis Patients One Year After Hurricane Katrina

Background:Hemodialysis patients experience a high degree of psychosocial impairment. Methods:The psychosocial status of hemodialysis patients after Hurricane Katrina was evaluated using the Hurricane Coping Self-Efficacy (HCSE) measure, the Short Form-12 Health Survey (physical component summary [PCS] and mental component summary [MCS]), and the Center for Epidemiologic Studies Short Depression Scale (CES-D). These scales were administered to 391 hemodialysis patients (86% participation rate), 7 to 14 months after Hurricane Katrina. Results:The mean score (standard deviation) was 36.2 (9.6) for the HCSE scale, 37.1 (10.9) and 46.7 (12.7) for the PCS and MCS, respectively, and 10.0 (6.5) on the CES-D. Symptoms of depression (CES-D scores ≥10) were present in 45.5% of patients. After age, race, and gender adjustment, evacuating less than 2 days before Hurricane Katrina making landfall and more fear of dying were associated with less favorable scores on the HCSE, MCS, and CES-D scales. Patients placed in a shelter and with a longer displacement had significantly lower MCS scores and more depressive symptoms. More depressive symptoms were observed among patients hospitalized in the month after the storm. Those who evacuated to a hotel, with more fear of dying and who were hospitalized in the month after Hurricane Katrina had lower scores on the PCS. Conclusions:Impaired psychosocial status was common among dialysis patients surviving Hurricane Katrina and associated with reduced coping. These data demonstrate the need for screening and management of psychosocial issues in hemodialysis patients after disasters.

Association of Posttraumatic Stress Disorder and Depression With All-Cause and Cardiovascular Disease Mortality and Hospitalization Among Hurricane Katrina Survivors With End-Stage Renal Disease

OBJECTIVES We determined the association of psychiatric symptoms in the year after Hurricane Katrina with subsequent hospitalization and mortality in end-stage renal disease (ESRD) patients. METHODS A prospective cohort of ESRD patients (n = 391) treated at 9 hemodialysis centers in the New Orleans, Louisiana, area in the weeks before Hurricane Katrina were assessed for posttraumatic stress disorder (PTSD) and depression symptoms via telephone interview 9 to 15 months later. Two combined outcomes through August 2009 (maximum 3.5-year follow-up) were analyzed: (1) all-cause and (2) cardiovascular-related hospitalization and mortality. RESULTS Twenty-four percent of participants screened positive for PTSD and 46% for depression; 158 participants died (79 cardiovascular deaths), and 280 participants were hospitalized (167 for cardiovascular-related causes). Positive depression screening was associated with 33% higher risk of all-cause (hazard ratio [HR] = 1.33; 95% confidence interval [CI] = 1.06, 1.66) and cardiovascular-related hospitalization and mortality (HR = 1.33; 95% CI = 1.01, 1.76). PTSD was not significantly associated with either outcome. CONCLUSIONS Depression in the year after Hurricane Katrina was associated with increased risk of hospitalization and mortality in ESRD patients, underscoring the long-term consequences of natural disasters for vulnerable populations.
