An exploratory study of pressure ulcers after spinal cord injury: relationship to protective behaviors and risk factors.

OBJECTIVES: To identify protective behaviors and risk factors associated with the development of pressure ulcers (PUs) after spinal cord injury (SCI). DESIGN: A cross-sectional study to evaluate the relationship between protective behaviors and risk factors and 3 PU outcomes: a current PU, PUs within the past year, and ever hospitalized for a PU. Logistic regression was then used to identify the variables most strongly associated with PU outcomes. SETTING: Data were collected by case managers employed by the Arkansas Spinal Cord Commission, an agency that provides services to persons with SCI. PARTICIPANTS: A total of 650 of 991 eligible individuals with SCI from a statewide population-based SCI registry participated. All ambulatory participants were eliminated, leaving 560 patients. Average age of the respondents was 27.2 years at injury (median age, 25yr) and 43.6 years at the time of the survey (median age, 42yr). MAIN OUTCOME MEASURES: A 200-item interview was developed to measure a broad range of outcomes associated with SCI (including secondary conditions such as PUs), as well as risk and protective behaviors related to these outcomes. RESULTS: Several characteristics and behaviors were related to PU outcomes. Being underweight (odds ratio [OR] = 2.18), having used medications to treat pain (OR = 1.33) or spasticity (OR = 1.31), having smoked at least 100 cigarettes over a lifetime (OR = 1.31), and being a current smoker (OR = 1.21) were associated with having a PU in the past year. Having completed a college degree (OR = 0.23), being married (OR = 0.49), and being currently employed (OR = 0.54) were associated with a lower risk of having a PU in the past year. Being underweight (OR = 1.94), having a history of incarceration (OR = 1.78), having attempted suicide (OR = 1.71), and reporting alcohol or drug treatment (OR = 1.65) were associated with having been hospitalized for a PU since injury. This study was unable to evaluate the efficacy of traditional health maintenance or protective behaviors for PUs, such as weight shifts or skin checks. CONCLUSIONS: PUs are least likely to occur among individuals who maintain normal weight, return to a work and family role, and who do not have a history of tobacco use, suicidal behaviors, or self-reported incarcerations, or alcohol or drug abuse. Additional research is needed to identify better the risk factors for the occurrence of PUs.

Spinal cord injury in Mississippi. Findings and evaluation, 1992-1994.

STUDY DESIGN: The Mississippi spinal cord injury surveillance system is both active and passive, designed to capture all cases of spinal cord injury through mandated reporting by multiple sources. Each case is confirmed by medical record review. OBJECTIVES: To describe the development of a state-wide spinal cord injury surveillance system, discuss findings from the system, and evaluate sensitivity. SUMMARY OF BACKGROUND DATA: In the United States, the annual incidence rate of spinal cord injury requiring hospital admission has been estimated at 32-50 per million. With prehospital fatalities included, the estimated incidence rate ranges from 43 to 55 per million population annually. METHODS: In the current study all cases identified during the first 2 years of operation of the spinal cord injury (SCI) system were included. To evaluate the sensitivity of the system, International Classification of Disease, Ninth Revision, Clinical Modification (ICD-9-CM) codes from each hospital's discharge database were used. RESULTS: The incidence rate among patients in hospitals and prehospital fatal cases was 77 per million. The rate for patients in hospitals was 59 per million. The incidence rate of spinal cord injury among males was 4.4 times higher than among females. Rates of spinal cord injury were highest among persons 20-24 years of age. Rates were similar for whites and blacks. The most frequent causes of spinal cord injury were motor vehicle collisions, violence, and falls. Additional cases were identified during the evaluation, resulting in a 94% sensitivity. CONCLUSIONS: Mississippi's spinal cord injury incidence rates are substantially higher than rates reported for other states except Alaska. The surveillance system was found to be very complete. Prevention efforts should focus on increasing safety belt usage, increasing alcohol awareness, and reducing violence.

Risk factors for mortality in the Bangladesh cyclone of 1991.

Cyclones continue to pose a dangerous threat to the coastal populations of Bangladesh, despite improvements in disaster control procedures. After 138,000 persons died in the April 1991 cyclone, we carried out a rapid epidemiological assessment to determine factors associated with cyclone-related mortality and to identify prevention strategies. A nonrandom survey of 45 housing clusters comprising 1123 persons showed that mortality was greatest among under-10-year-olds (26%) and women older than 40 years (31%). Nearly 22% of persons who did not reach a concrete or brick structure died, whereas all persons who sought refuge in such structures survived. Future cyclone-associated mortality in Bangladesh could be prevented by more effective warnings leading to an earlier response, better access to designated cyclone shelters, and improved preparedness in high-risk communities. In particular, deaths among women and under-10-year-olds could be reduced by ensuring that they are given special attention by families, neighbours, local authorities, and especially those in charge of early warnings and emergency evacuation.

Renal cell cancer among paperboard printing workers.

A physician's alert prompted us to investigate workers' cancer risk at a paperboard printing manufacturer. We conducted a retrospective cohort mortality study of all 2,050 persons who had worked at the facility for more than 1 day, calculated standardized incidence ratios (SIRs) for bladder and renal cell cancer, and conducted a nested case-control study for renal cell cancer. Standardized mortality ratios (SMRs) from all causes [SMR = 1.0, 95% confidence interval (CI) = 0.9-1.2] and all cancers (SMR = 0.6, 95% CI = 0.3-1.0) were not greater than expected. One bladder cancer and one renal cell cancer were included in the mortality analysis. Six incident renal cell cancers were observed, however, compared with less than two renal cell cancers expected (SIR = 3.7, 95% CI = 1.4-8.1). Based on a nested case-control analysis, the risk of renal cell cancer was associated with overall length of employment but was not limited to any single department or work process. Although pigments containing congeners of dichlorobenzidine and o-toluidine had been used at the plant, environmental sampling could not confirm any current exposure. Several limitations and a potential selection bias limit the inferences that can be drawn.
